HYPOTHESIS
That factors affecting outcomes of surgical resection in the treatment of gastric cancer can be identified using a large US database.
DESIGN
Retrospective observational study.
SETTING
The Nationwide Inpatient Sample from January 1, 1998, through December 31, 2003.
PATIENTS
We included 13 354 patient discharges (approximately 66 096 nationally by weighted analysis) who underwent gastric resection for neoplasm.
MAIN OUTCOME MEASURE
In-hospital mortality. Univariate analyses were performed by means of chi(2) tests. A multivariate logistic regression was performed to determine which variables were independently predictive of in-hospital mortality.
RESULTS
During the study period, 50 738 patients (approximately 250 420 nationally) were discharged with the diagnosis of gastric neoplasm. Of those, 13 354 (26.3%) underwent gastric resection during their hospitalization. In-hospital mortality for patients undergoing surgery was 6.0%, without significant change from 1998 through 2003. Factors predictive of significantly increased in-hospital mortality included low annual hospital surgical volume (lowest [<or= 4 gastrectomies per year] vs highest [>or= 11 gastrectomies per year], 6.8% vs 4.9%; adjusted odds ratio [OR], 1.5; 95% confidence interval [CI], 1.2-1.8]), older patient age (50-69 vs <50 years, 4.0% vs 2.1%; adjusted OR, 1.5; 95% CI, 1.1-2.2) (>or =70 vs <50 years, 8.6% vs 2.1%; adjusted OR, 2.9; 95% CI, 2.0-4.3), male sex (male vs female, 6.7% vs 5.0%; adjusted OR, 1.3; 95% CI, 1.1-1.5), and procedure type (total gastrectomy vs all other resections, 8.0% vs 5.3%; adjusted OR, 1.4; 95% CI, 1.2-1.7).
CONCLUSIONS
Higher annual surgical volume is predictive of lower in-hospital mortality for patients undergoing gastric resection for neoplasm. Other factors significantly associated with superior outcomes after gastric resection included diagnosis type, procedure type, younger age, female sex, and fewer comorbid conditions.

The goal of this article is to discuss whether the Sustainable Development Goals address the cooperation necessary to facilitate a system of transboundary water governance. For the purpose of this analysis, a Good Transboundary Water Governance Matrix has been developed. We find that transboundary water governance requires a holistic interpretation and implementation of the Sustainable Development Goals understood as a whole. In particular, good governance and, ultimately, sustainable development require stakeholders to focus not only on water (Goal 6) but also on Goal 16, which focuses on international cooperation.

Kegiatan ini bertujuan untuk pengaplikasian ilmu mahasiswa yang telah didapatkan saat kuliah dan menggali potensi diri dalam bermasyarakat serta memecahkan suatu masalah yang terjadi di dalam masyarakat, terutama dibidang kesehatan. Metoda yang digunakan adalah survey dan observasi langsung kelapangan. Berdasarkan survey yang telah dilaksanakan terlebih dahulu, nagari Koto Tangah terdiri dari 6 jorong dengan potensi yang bermacam-macam. Di Jorong Koto Tangah, tambun ijuak dan seberang parit, dan batu tanyuah masyarakatnya lebih banyak bertani dan bekerja disawah, hal ini juga tergambar dari pemandangan daerahnya yang dipenuhi dengan pematang sawah. Jorong Piladang termasuk jorong yang sangat maju dan terluas dibandingkan jorong lainnya, masyarakat di jorong ini banyak yang mempunyai usaha perternakan ayam dan juga sebagai pedagang. Jorong Sungai Cubadak merupakan jorong yang menjadi pusat perhatian saya, karena setiap rumah di jorong ini, mempunyai aktifitas yang sama yakni mempunyai usaha membuat kerupuk dan menjadi pemasok kerupuk ke berbagai daerah, seperti ke Bukittinggi, Payakumbuh dan sekitarnya. Namun, disamping itu masyarakat seringkali tidak menyadari pentingnya kesehatan dan kebersihan. Masyarakat sangat terlena oleh pekerjaan atau kesibukkannya sehari-hari. Sehingga, saya sebagai mahasiswa dari jurusan farmasi yang bergerak dibidang kesehatan merasa bertanggung jawab untuk menyampaikan dan memberitahu informasi kesehatan kepada masyarakat. Dari kegiatan yang telah dilaksanakan di nagari Koto Tangah, terlihat adanya warna-warna mencolok pada kerupuk hasil industri rumah tangga yang terkadang hanya dibiarkan saja tergeletak dijemur dijalanan yang penuh polusi. Oleh karena itu saya mempunyai program pengenalan zat tambahan berbahaya pada makanan (zat adiktif). Selanjutnya memberikan pengetahuan mengenai “Dagusibu” (Dapatkan, Gunakan, Simpan, Buang), agar masyarakat paham mengenai cara pengelolaan obat yang baik dan benar.

Several fully tert-butyldimethylsilyl protected mono- saccharides reacted with boron trichloride in tetrahydrofuran to effect a regioselective cleavage at the sites of primary alcohols. An application of this methodology was illustrated in an efficient approach to the synthesis of L-gulose from D-gluconolactone. Selective protection and deprotection of polyfunctional molecules present a critical challenge in organic synthe- sis. Particularly in carbohydrate chemistry, many prob- lems result from how to distinguish multiple hydroxyl groups of similar reactivity. A variety of trialkylsilyl groups have been developed for the protection of free hy- droxyl groups due to their easy preparation and selective attachment. 1-3 In order to remove the silyl protection of a primary alcohol selectively in the presence of secondary and tertiary ones, most methods require distinguishable si- lyl groups for different hydroxyl functionalities. 4 This process often increases the difficulty of preparation and the number of synthetic steps. 4 It would be desirable that one can use only one silyl group for protection of several hydroxyl groups in a molecule, and the subsequent depro- tection can be conducted in a regioselective manner. Al- though effective procedures have been used in some specific examples, 5 there are only a few reports on such selective deprotection of carbohydrate molecules. 6 In the course of L-gulose synthesis, we found that BCl 3 was effective to cleave primary tert-butyldimethylsilyl (TBDMS) ether without affecting the same groups at secondary positions.

ABSTRACT The prejudices and stereotypes associated with Alzheimer’s disease (AD) are based on contents that highlight the most negative and dramatic aspects of the symptoms of this disease. This is reinforced by the preponderance of negative representations related to AD. In this paper, these representations have been analyzed as frames. The most dominant frame used to represent dementia is “body-mind dualism,” and its alternative is the “body-mind unity” counter-frame. This study aims to define the impact of different messages inspired by the Dualism frame and the Unity counter-frame in the collective representation and meaning given to AD. Posters of simulated health campaigns about AD were designed, combining contents related to the Dualism frame and the Unity counter-frame, and were shown to 85 participants. To analyze the impact of both types of frameworks, a pre-post record of the attitudes of the participants toward AD was conducted using the Attitudes toward Dementia Scale. The assessment of the campaign and the self-report emotions were also registered. Participants’ eye movements were measured during exposure to the posters. Attitudes toward dementia were found to be significantly more positive following exposure to discourses characteristic of the Unity counter-frame. Likewise, the dualism discourse evoked more sadness and anger. Moreover, the posters that used the discourse of the Unity counter-frame were considered more useful. We concluded that attitudes toward dementia are influenced by framing. Designing suitable health campaigns using these frames could help mitigate the attitudes and stigma associated with AD.

We propose a novel end-to-end curriculum learning approach that leverages large volumes of unlabelled great ape camera trap footage to improve supervised species detector construction in challenging real-world jungle environments. In contrast to previ-ous semi-supervised methods, our approach gradually improves detection quality by steering training towards virtuous self-reinforcement. To achieve this, we propose integrating pseudo-labelling with dynamic curriculum learning policies. We show that such dynamics and controls can avoid learning collapse and gradually tie detector adjustments to higher model quality. We provide theoretical arguments and ablations, and confirm signif-icant performance improvements against various state-of-the-art systems when evaluating on the Extended PanAfrican Dataset holding several thousand camera trap videos of great apes. We note that system performance is strongest for smaller labelled ratios, which are common in ecological applications. Our approach, although designed with wildlife data in mind, also shows competitive benchmarks for generic object detection in the MS-COCO dataset, indicating wider applicability of introduced concepts. We publish all relevant source code, network weights, and data access details for full reproducibility.

The effect of ethanol extract of whole plant of Cynoglossum zeylanicum on Oral Glucose Tolerance was determined. Ethanol extract of Cynoglossum zeylanicum were evaluated for Oral Glucose Tolerance Test (OGTT) in normal and alloxan induced diabetic rats. Oral administration of ethanol extract at doses of 100 &150mg/kg body weight shows that the extract promote glucose uptake. These results suggest that the ethanol extract of Cynoglossum zeylanicum whole plant will be useful in the treatment of impaired oral glucose tolerance.

Background: To examine the effect of early menarche (EM) on adolescent body composition and fat distribution, and to explore the possible contribution of birth weight (BW) to this relationship. Methods: From the cross-sectional AVENA study, 788 girls (aged 13–18.5 years) were selected. Post-menarcheal body composition was estimated by anthropometric methods. Results: BW Z-score was associated with age at menarche (β = 0.496, p < 0.001). EM (age of menarche <12 years) adolescents were shorter, had a higher body mass index (BMI), fat free mass index (FFMI), fat mass index (FMI) and waist circumference (all p < 0.01). BW was associated with height (p < 0.001), BMI Z-score (p < 0.01), FFMI (p < 0.01) and FMI (p < 0.05). These relationships did not change when the analysis was controlled for age of menarche. Height and FFM were lower in EM (p < 0.01), but these effects seem to be due to the BW (p < 0.01). Conclusion: EM was strongly associated with unhealthy body composition in female adolescents, but these relationships seem to be due to the programming effect of BW.

Punctate inner choroidopathy (PIC) is a rare inflammatory chorioretinopathy that predominantly affects young myopic women. Visual prognosis is generally good, but occurrence of choroidal neovascularization (CNV) is common and may be vision threatening. Case reports and short case series support the effectiveness of intravitreal anti-vascular endothelial growth factor (VEGF) agents (ranibizumab and bevacizumab) for CNV associated with PIC given their anti-angiogenic and anti-inflammatory effects. Evidence concerning aflibercept, a more recent intravitreal anti-VEGF, is limited to a single case report. In this case report, we illustrate the case of a 43-year-old myopic woman presenting with visual acuity loss and distortion in the right eye over the last 5 days in whom CNV associated with PIC was diagnosed. Treatment with 1 injection per month of intravitreal aflibercept for 2 months and full-dose oral prednisone for 1 week, being tapered afterwards, improved visual acuity and resolved CNV, with benefits lasting up to 24 months.

Wnt/β-catenin signaling plays a major role in the development of the nervous system and contributes to neuronal plasticity. However, its role in myelination remains unclear. Here, we identify the Wnt/β-catenin pathway as an essential driver of myelin gene expression. The selective inhibition of Wnt components by small interfering RNA or dominant-negative forms blocks the expression of myelin protein zero (MPZ) and peripheral myelin protein 22 (PMP22) in mouse Schwann cells and proteolipid protein in mouse oligodendrocytes. Moreover, the activation of Wnt signaling by recombinant Wnt1 ligand increases by threefold the transcription of myelin genes and enhances the binding of β-catenin to T-cell factor/lymphoid-enhancer factor transcription factors present in the vicinity of the MPZ and PMP22 promoters. Most important, loss-of-function analyses in zebrafish embryos show, in vivo, a key role for Wnt/β-catenin signaling in the expression of myelin genes and in myelin sheath compaction, both in the peripheral and central nervous systems. Inhibition of Wnt/β-catenin signaling resulted in hypomyelination, without affecting Schwann cell and oligodendrocyte generation or axonal integrity. The present findings attribute to Wnt/β-catenin pathway components an essential role in myelin gene expression and myelinogenesis.

AMAC: Bugune kadar migrenin patofizyolojisini anlamaya yonelik bircok klinik ve deneysel calisma yapilmistir. Bu calismalarin sonucunda noronal bir cikis noktasina ragmen migrende intrakranial damarlardaki degisikliklerin de patofizyolojide onemli bir basamak olduguna inanilmaktadir. Biz, transkraniyal Doppler ultrasonografi kullanarak, aurali ve aurasiz migrenlilerde, atak ve atak sonrasinda gorsel uyari ile posterior serebral arterde olusan norovaskuler reaktivite ve nefes tutma ile posterior serebral arterde olusan vaskuler reaktiviteyi degerlendirmeyi amacladik. GEREC ve YONTEM: Calismaya aurasiz migren tanisi almis 18, aurali migren tanisi almis 9 hasta ve 26 kontrol kisisi alindi. Tum hastalara agri ataginda ve bas agrisi tamamen gectikten en az 5 gun sonra toplam iki kez olmak uzere transkraniyal Doppler ile basit gorsel uyari ve ardindan nefes tutma testi yapildi. BULGULAR: Hem aurasiz hem de aurali migren hastalarinda atak sirasinda ve atak disinda elde edilen gorsel reaktiviteler arasinda farklilik saptanmamistir. Aurasiz migren hastalarinda nefes tutma reaktivitesi de benzer bulunmustur. Buna karsin aurali migren hastalarinda atakta (%36.7) ve atak disinda (%60.6) elde edilen nefes tutma reaktiviteleri arasinda anlamli farklilik elde edilmistir (p<0,001). Aurasiz migren hastalarinda hem atak doneminde (%33.8) hemde atak disinda (%33.1) gorsel reaktivite kontrol grubuna (%39.4) gore anlamli derecede dusuk bulunmustur (p<0,05). Atak sirasinda nefes tutma reaktivitesi aurali migrende (%36.7) kontrol grubuna (%53.9) gore anlamli derecede dusuk bulunmustur (p<0.02). YORUM: Calismamiz, hem gorsel reaktivite hem de nefes tutma reaktivitesinin arka serebral arterde yapilan ilk calismasidir. Aurali migren hastalarinda atakta veya atak disinda kontrol grubuna gore farkli gorsel uyari cevabi olusmazken, aurasiz migren hastalarinda atakta ve atak disinda gorsel uyari cevabi azalmis olarak bulunmustur. Bu sonuclar; a) Aurasiz migren hastalarinda noronal enerji rezervinin, bas agrisi atagina bagli olmaksizin, aurali migren hastalarina gore daha az oldugunu dusundurebilir; b) Aurali migren hastalarinda aura fazina eslik eden yayilan depresyonun aurali migren hastalarinin noronal enerji rezervi uzerine olumsuz etki etmedigini, hatta koruyucu etkisi oldugunu dusundurebilir; c) Bundan baska, aurali migren hastalarinda noronal hiperaktivitenin aurasiz migren hastalarina gore daha fazla oldugu da dusunulebilir. Buna karsin nefes tutma ile olusan vaskuler reaktivite atakta aurali migren grubunda azalmis, ancak atak sonrasinda normale donmustur. Bu sonuc ise aurali migren hastalarinda vaskuler yatagin daha fazla etkilendigine isaret edebilir. Anahtar Sozcukler: Bas agrisi, migren, nefes tutma, ultrasonografi, vazoreaktivite.

Tissue engineering is a field in progressive expansion and requires constant updates in methods and devices. One of the central fields is the development of biocompatible, biodegradable, and injectable scaffolds, such as collagen microcarriers. To enhance cell attachment and produce a cost-effective cell culture solution with local stimulation of cells, basic fibroblast growth factor (bFGF) or transforming growth factor-β1 (TGF-β1) was covalently immobilized on microcarriers either by 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/N-hydroxysuccinimide (EDC/NHS) or riboflavin/UV (RB/UV) light-mediated cross-linking. Collagen microcarriers cross-linked with bFGF or TGF-β1 were used for expansion and chondrogenic differentiation of human mesenchymal stem cells (MSCs). Evaluation methods included cell viability test, chondrogenic marker expression (aggrecan and collagen type I and type II), histological detection of proteoglycans, and immunohistochemical analysis. Cross-linking strengthened the collagen structure of the microcarriers and reduced collagenase-mediated degradation. MSCs effectively proliferated on microcarriers cross-linked with bFGF, especially by EDC/NHS cross-linking. Chondrogenic differentiation of MSCs was induced by TGF-β1 cross-linked on microcarriers, promoting gene expression and protein accumulation of aggrecan and collagen type I and type II, as well as proteoglycans. Cross-linking by RB/UV enhanced chondrogenesis more than any other group. In addition, cross-linking reduced scaffold shrinkage exerted by MSCs during chondrogenesis, a desirable feature for microcarriers if used as tissue defect filler. In conclusion, cross-linking of bFGF or TGF-β1 to collagen microcarriers supported in vitro proliferation and chondrogenesis, respectively. If translated in vivo and in clinical practice, such approach might lead a step closer to development of a cost-effective and locally acting device for cell-based therapy.

A general model based on electronegativity equalization method (EEM) is proposed for a quantitative formulation of barrier formation at reactive metal/organic interfaces. The present model predicts for molecular bonding formation a linear dependence of barrier heights on the degree of partial charge transfer, which is determined by the electronegativity difference between metals and molecules. Also, the calculated barrier heights show good agreement with the empirical values. It suggests that the EEM-based electronegativity model has captured the essence of barrier formation at reactive metal/organic interfaces, and that electronegativity is a fundamental factor in characterizing the chemical trend of barrier heights.

aged ≥50 years to assess the likelihood of meeting the CDC’s recommended 150-minutes of moderate physical activity per week. Walkability was measured via Walk ScoreTM which is used to categorize areas that are walkable (Walk ScoreTM ≥50) versus car-dependent (Walk ScoreTM <50). Neighborhood cohesion/safety was measured via a summary score using multiple survey items (e.g., many people walk/bike in my neighborhood). We used multivariate logistic regression to predict walking ≥150 minutes/week versus <150 minutes, while adjusting for age, sex, race/ethnicity, marital status, income, difficulty with walking, having someone to walk with, perceived neighborhood cohesion/safety, and walkability. Results: Factors associated with a greater likelihood of walking ≥150 minutes/week included being age ≥65 versus 50-64 (OR=1.76, 95% CI=1.02-3.04), having high perceived neighborhood cohesion/safety versus low (OR=2.4, 95% CI=1.15-5.09), and living in a walkable versus car-dependent neighborhood (OR=2.69, 95% CI=1.15-6.30). Factors associated with a lower likelihood of walking ≥150 minutes/ week included having some difficulty in walking versus none (OR=0.24, 95% CI=0.10-0.61). Conclusions: Identifying neighborhood factors associated with promoting walking among older adults can enable stakeholders at several levels (e.g., policy makers, researchers, urban planners) to plan interventions focusing on the built environment.

Abstract We consider a problem whether Kodaira’s -Lemma holds on weakly 1-complete Kähler manifolds or not. This problem was proposed by S. Nakano. We prove that the Lemma holds for some class of complex quasi-tori ℂ n /Γ, and it does not hold for the other class of them. Every complex quasi-tori is weakly 1-complete and complete Kähler. Then we get a negative answer for the above problem.

Introduction There is increasing evidence that pre-eclampsia, a principal cause of maternal morbidity, may also be a risk factor for future cardiovascular and cerebrovascular events. This review aimed to assess the current evidence and quantify the risks of cardiovascular and cerebrovascular events that may follow a diagnosis of pre-eclampsia. Methods MEDLINE and EMBASE were searched with no language restrictions, as were core journals and reference lists from reviews. Case control and cohort studies which reported cardiovascular and cerebrovascular diseases diagnosed more than 6 weeks postpartum, in women who had history of pre-eclampsia relative to women who had unaffected pregnancies, were included. Results 24 articles were included in the systematic review and 19 in the meta-analysis. Women with a history of pre-eclampsia or eclampsia were at significantly increased odds of fatal or non-fatal cardiovascular disease (OR 2.27, 95% CI 1.83 to 2.82) and cerebrovascular disease (OR 2.46, 95% CI 1.57 to 3.85). Among pre-eclamptic women, pre-term delivery was not associated with an increased risk of a future cardiovascular event (RR 1.28, 95% CI 0.82 to 1.99). Conclusion Women diagnosed with pre-eclampsia are at increased risk of future cardiovascular or cerebrovascular events, with an estimated doubling of risk compared to unaffected women. This has implications for the follow-up of all women who experience pre-eclampsia, not just those who deliver pre-term. This association may reflect shared common risk factors for both pre-eclampsia and cardiovascular and cerebrovascular disease.

Purpose : To evaluate patients’ perception regarding ovarian cyst as well as their awareness of the symptoms and health management of the disease. Methods : A quantitative research approach was used to conduct this study. Patients were selected from the Gynecology wards, Hayatabad Medical Complex, Peshawar and a questionnaire was designed to evaluate the patients’ knowledge and awareness. Results : When women were asked if they had prior knowledge about the ovarian cyst, 37 (58.7 %) responded that they were first told by the physician during their visit to the clinic or hospital while the patients responded, “Still don’t know” are 22 (34.9 %). With respect to educational level of the patients, they seemed to be less aware of the disease. Their perception regarding the disease is that they had a “water filled” balloon or tumor. Conclusion : Prior to discharge of an ovarian cyst patient from the hospital, she should be counseled on the disease and successful treatment outcomes. Counseling of the patients may result in compliance with therapy, good quality of life and lower economic burden. Keywords : Ovarian cyst, Menstrual cycle, Awareness, Perception, Treatment outcomes

Introduction Health organisations should support healthcare workers who are physically and psychologically affected by patient safety incidents (second victims). There is a growing body of evidence which focuses on second victim support interventions. However, there is still limited research on the elements necessary to effectively implement and ensure the sustainability of these types of interventions. In this study, we propose to map and frame the key factors which underlie an effective implementation of healthcare worker support interventions in healthcare organisations when healthcare workers are physically and/or emotionally affected by patient safety incidents. Methods and analysis This scoping review will be guided by the established methodological Arksey and O’Malley framework, Levac and Joanna Briggs Institute (JBI) recommendations. We will follow the JBI three-step process: (1) a preliminary search conducted on two databases; (2) the definition of clear inclusion criteria and the creation of a list of search terms to be used in the subsequent running of the search on a larger number of databases; and (3) additional searches (cross-checking/cross-referencing of reference lists of eligible studies, hand-searching in target journals relevant to the topic, conference proceedings, institutional/organisational websites and networks repositories). We will undertake a comprehensive search strategy in relevant bibliographic databases (PubMed/MEDLINE, Embase, CINHAL, Web of Science, Scopus, PsycInfo, Epistemonikos, Scielo, Cochrane Library and Open Grey). We will use the Mixed Methods Appraisal Tool V.2018 for quality assessment of the eligible studies. Our scoping review will be guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews. Ethics and dissemination This study will not require ethical approval. Results of the scoping review will be published in a peer-review journal, and findings will be presented in scientific conferences as well as in international forums and other relevant dissemination channels.

Microfocus X-ray diffraction has been used to analyze interfacial stress transfer in two-phase polymer systems consisting of a highly oriented polymer fiber in an isotropic resin matrix. Synchrotron radiation has been used to obtain high-quality X-ray diffraction patterns from single poly(p-phenylene benzobisoxazole) (PBO) and poly(p-phenylene terephthalamide) (PPTA) fibers in these model two-phase systems. Two different specimen geometries were studied: a fully embedded fiber composite and a microdroplet specimen. A procedure is demonstrated whereby well-defined diffraction patterns can be obtained, using a 5 mum diameter X-ray beam, from individual 12 mum diameter polymer fibers in over 1 mm thickness of resin by subtracting the scattering of the resin matrix from that of the fiber and matrix to obtain a diffraction pattern of the fiber only. Shifts of meridional diffraction peaks of the fibers were determined as a function of stress and were converted into crystal strain. The fiber stress was then determined from calibrations obtained from previous X-ray diffraction studies of fiber deformation. The point-to-point variation of fiber stress was mapped along the fibers in the specimens, and a force-balance approach was used to determine the shear stress at the fiber-matrix interface. This present study was concerned only with an optically transparent polymer matrix, but the possible extension of the technique to opaque matrices and other multiphase polymer systems is discussed.

Food restriction (FR) augments the behavioral and reinforcing effects of psychomotor stimulants such as cocaine or amphetamine; effects that may be related to the capacity of FR to increase plasma levels of ghrelin (GHR), a 28‐amino acid orexigenenic peptide linked to activation of brain dopamine systems. The present study used wild‐type (WT) mice or mutant mice sustaining knockout of either GHR [GHR(−/−)] or of the growth hormone secretagogue receptor [GHS‐R(−/−)] and subjected to FR or not to evaluate the role of GHR and GHS‐R in cocaine‐stimulated locomotion. WT, GHR(−/−), and GHS‐R(−/−) mice were either restricted to 60% of baseline caloric intake or allowed to free‐feed (FF). Mice were treated with 0, 1.25, 2.5 and 5.0 mg/kg cocaine on separate test days (in random dose order) and forward locomotion was recorded on each drug day for 45 minutes after drug dosing. Food (and water) was available immediately after (but not during) each activity test. For FF mice, there was no interaction between cocaine and GHR status on locomotion. FR‐WT mice treated with saline exhibited significant increases in anticipatory locomotion (relative to FF‐WT mice), whereas FR‐GHS‐R(−/−) mice did not. Cocaine significantly increased locomotion in FR‐GHR(−/−) and FR‐GHS‐R(−/−) mice to the levels noted in FR‐WT mice. These results suggest that GHS‐R activity, but not GHR activity, is required for FR to augment food‐associated anticipatory locomotion, but do not support the contention that GHR pathways are required for the capacity of FR to augment the acute effect of cocaine on locomotion.

The structure and the terminology of the story are important for a comparison with the later narratives concerning prophetic consultation. The occasion for the consultation is a situation of crisis: War is at hand. One goes to the medium for information and guidance. An answer is given, foretelling what is going to happen. A comparison with Hittite, Assyrian and Sumerian parallels has called to attention a vocable ab with the meaning of a ritual hole in the ground, dug to give infernal deities or spirits of the deceased access to the upper world for a brief interval of time. According to the author, 'obot and jidd e onim were no sacred pits nor wizards, but the ghosts of the deceased fathers and the instruments representing them. The consultation of those ghosts was forbidden as a foreign practice. It was replaced by the typical Israelite practice of consulting Jahweh through the prophets. Keywords: Jahweh; prophets; wizards

The multipole approximation is a sufficient method for fast calculations of the electromagnetic field and for complex electromagnetic environments with many field sources. In this paper, the influences on the superposition of electromagnetic fields generated by multipole sources are under consideration. The phase angle of the multipole field sources is unknown when estimating multipole parameters. Therefore, the influence of random phase angles on interference patterns is under investigation. This paper demonstrates two phase independent superposition methods. Additionally, a probability distribution for field strength values is derived. This distribution demonstrates the influence of random variables on the probability of field strength values.

Interfacial charge recombination dynamics in nanocrystalline SnO2 and TiO2 thin films sensitized with phosphonate-derivatized ruthenium chromophores (Ru(bpy)2(4,4′-(PO3H2)2bpy)]2+, RuP) have been investigated in aqueous media by nanosecond transient absorption spectroscopy. Back electron transfer (BET) rates for RuP–SnO2 were observed to be 2–3 times greater than for RuP–TiO2. Additionally, rates of charge recombination for RuP–TiO2 show a significant pH dependence, while only a subtle influence of pH is observed for BET in RuP–SnO2. Cyclic voltammetry measurements indicate the exponential distribution of intra-band-gap trap states varies with pH for both SnO2 and TiO2 nanocrystalline thin films. BET rates for RuP–SnO2 and RuP–TiO2 are correlated with the distribution, identity, and occupation of localized trap states within the nanocrystalline metal oxide films, which are pH specific. Recombination between injected electrons and oxidized chromophores is influenced by the identity of metal oxide localized...

The authors study issues related to string level acoustic modeling in continuous speech recognition. They derive the formulation of minimum string error rate training. A minimum string error rate training algorithm, segmental minimum string error rate training, is described. It takes a further step in modeling the basic speech recognition units by directly applying discriminative analysis to string level acoustic model matching. One of the advantages of this training algorithm lies in its ability to model strings which are competitive with the correct string but are unseen in the training material. The robustness and acoustic resolution of the unit model set can therefore be significantly improved. Various experimental results have shown that significant error rate reduction can be achieved using this approach.<<ETX>>

ABSTRACT Suspense is a cognitive and affective state that is often experienced in the anticipation of information and contributes to the enjoyment and consumption of entertainment such as movies or sports. Ely et al. proposed a formal definition of suspense which relies upon predictions about future belief updates. In order to empirically evaluate this theory, we designed a task based on the casino card game Blackjack where a variety of suspense dynamics can be experimentally induced. Our behavioural data confirmed the explanatory power of this theory. We further compared this formulation with other heuristic models inspired by studies in other domains such as narratives and found that most heuristic models cannot well account for the specific temporal dynamics of suspense across wide range of game variants. We additionally propose a way to test whether experiencing greater levels of suspense motivates more game-playing. In summary, this work is an initial attempt to link formal models of information and uncertainty with affective cognitive states and motivation.

Abstract The proliferation of increasingly more sophisticated analytical separation systems, often incorporating increasingly more powerful detection techniques, such as high‐resolution mass spectrometry, causes an urgent need for highly efficient data‐analysis and optimization strategies. This is especially true for comprehensive two‐dimensional chromatography applied to the separation of very complex samples. In this contribution, the requirement for chemometric tools is explained and the latest developments in approaches for (pre‐)processing and analyzing data arising from one‐ and two‐dimensional chromatography systems are reviewed. The final part of this review focuses on the application of chemometrics for method development and optimization.

Abstract
A greenhouse experiment of dose-response was carried out to improve the efficacy of sethoxydim with nine vegetable oils in Research Greenhouse of Ferdowsi University of Mashhad in 2012. The experiment was done in a factorial experiment with a completely randomized design including 0, 22/5, 46/8, 93/75, 187/5, 281/25 and 375 g active ingredient of sethoxydim ha-1 with and without turnip, olive, soybean, corn, sunflower, canola, sesame, castor, and cotton oils. Moreover, an experiment was carried out to determine fatty acid content and quantity of each vegetable oil in Laboratory of Fazle Neyshabur Co. All vegetable oils improved the efficiency of sethoxydim to control wild oat. They can ranked based on relative potency value to turnip > olive > soybean > corn > sunflower > canola > sesame > castor > cotton. The overall results showed that with increasing the content of unsaturated fatty acids in vegetable oils, the efficacy of sethoxydim improved. Turnip and cottonseed oils with the highest and lowest percentage of unsaturated fatty acids had the highest and lowest performance, respectively. Among the polyunsaturated fatty acids compound, linoleic acid content had a key role in the efficiency. There was a negative relationship between linoleic acid content and the performance of vegetable oils. No significant toxicity of sethoxydim in present of vegetable oils on sugar beet and canola was observed.

Electronic shops provide an excellent choice to buy without leaving home. Nevertheless, people frequently have problems to find what they look for because of the wide range of items that e-shops offer. Recommender Systems are applications that help people in their searches in e-shops. They deal with information that people provide which is usually related to opinions, tastes and perceptions, and therefore, it is difficult to express them by means of precise numeric scales. Fuzzy linguistic approach provides a better way to express this kind of information. In this contribution we propose a Knowledge Based Recommender System that uses the fuzzy linguistic approach to handle the uncertainty of the human opinions and provides a multigranular context that allows users to utilize the term set that better fits with their degree of knowledge.

This paper examines an important continuity in the political economy of the Philippines: the interplay between domestic merchant capitalists and the state over the role of the state in the Philippine economy. During the Marcos regime, this interplay increasingly took the form of competition between state mercantile interests and ‘private’ merchant interests. This competition is still being played out. To better understand the nature of the competition, consideration is focused on two essential contemporary facts: the Philippines has a major external debt crisis and the Philippines, still predominantly an agrarian country, suffers from stagnant productivity growth and enduring rural poverty. While the Philippine external debt problem can be attributed in significant part to various international hegemonic interests, the analysis concludes that the characteristics of the crisis primarily reflect changing state/class/economy configurations within the Philippines. These same configurations, in turn, significantly influence the implications of the external debt crisis on Philippine agriculture.

This study was undertaken to assess the efficacy of omentoplasty in 12 cases of bronchopleural fistula after pneumonectomy. All fistulas formed within 16 days after the primary operation (median, 7 days). In 10 cases, omentoplasty was performed within 10 hours of diagnosis; the other 2 cases were treated at 28 and 31 hours. The greater omentum was mobilized through a laparotomy and secured tightly around the bronchial stump using original principles of fixation. After omentoplasty, dehiscence of the bronchial stump was observed in 5 (42%) patients, but owing to reinforcement with greater omentum, recurrence of the fistula was observed in only one case. In 3 patients, recurrence of pleural empyema did not lead to the return of the bronchopleural fistula. Hospital mortality was 8.3% (one patient). In patients without bronchopleural fistula recurrence, the median postoperative hospital stay was 31 days. Early omentoplasty for bronchopleural fistula after pneumonectomy is an effective procedure that eliminates purulent bronchopleural complications completely within the shortest possible period of time.

In wideband spectrum sensing, compressive sensing approaches have been used at the receiver side to decrease the sampling rate, if the wideband signal can be represented as sparse in a given domain. While most studies consider the reconstruction of primary user's signal accurately, it is indeed more important to analyze the presence or absence of the signal correctly. Furthermore, these studies do not consider the achievable lower bounds of reconstruction error and how well the selected method performs correspondingly. Motivated by these issues, we investigate in detail the primary user detection performance of Bayesian compressive sensing (BCS) approach in this paper. Accordingly, we (i) determine the BCS signal reconstruction performance in terms of mean-square error (MSE), compression ratio and signal-to-noise ratio (SNR), and compare it with the conventionally used basis pursuit approach, (ii) determine how well BCS performs compared with the Bayesian Cramer-Rao lower bound (BCRLB) of the signal reconstruction error, and (iii) assess the probability of detection performance of BCS for various SNR and compression ratio values. The results of this study are important for determining the achievable performance of BCS based spectrum sensing.

Sarcoid is a generalized disease with fairly characteristic but nonspecific, noncaseating granulomas found most frequently in the hematopoietic tissues. Clinically it is usually manifested by a chronic course with fever and various combinations of lymphadenopathy, splenomegaly, and hepatomegaly. Leukopenia and reversal of the protein albumin-globulin ratio are frequent. A fairly characteristic diffuse lesion in the lung fields, hilar lymphadenopathy, and, less frequently, osteolytic lesions of the small bones of the hands and feet may be found on x-ray examination. A negative tuberculin reaction, even with old tuberculin in 1:10 dilution, and a positive Kveim reaction occur in almost all patients. Since numerous diseases may mimic sarcoid in one or more of these respects, it is necessary that one demonstrate as many of these phenomena as possible in order to make a definite diagnosis. More important and usually more difficult is the demonstration of the non-caseating granuloma. The usual method is

The finding that insulin-like growth factor (IGF)-binding protein-5 (IGFBP-5) binding to mouse osteoblasts was capable of being downregulated by IGFBP-5 suggested that the 420-kDa membrane protein, which interacted with IGFBP-5, may be a signaling receptor (Andress, D. L. J. Biol. Chem. 270: 28289-28296, 1995). In the current study, a carboxy-terminal IGFBP-5 peptide, IGFBP-5-(201-218), which was found to competitively inhibit125I-IGFBP-5 binding and to specifically bind to osteoblast monolayers, was used to affinity-purify the 420-kDa membrane protein. Coincubation of the affinity-purified membrane protein with [32P]ATP resulted in autophosphorylation at serine residues. Serine phosphorylation of the 420-kDa protein was enhanced by intact IGFBP-5, IGFBP-5-(1-169), and IGFBP-5-(201-218). When the IGFBP-5 receptor was incubated with dephosphorylated casein in the presence of [32P]ATP, casein became phosphorylated on serine residues. These data indicate that IGFBP-5 stimulates the phosphorylation of the IGFBP-5 receptor and suggest that serine/threonine kinase activation may be important in mediating some of the IGF-independent effects of IGFBP-5.

The acquisition of transition metal ions by pathogenic bacteria is crucial to their growth and survival within the human host, however, the mechanisms of metal ion homeostasis in streptococci are unknown. The scaCBA operon in the human oral bacterium Streptococcus gordonii encodes the components of an ABC‐type transporter for manganese (Mn2+). Production of substrate‐binding lipoprotein ScaA was increased approximately fivefold in cells cultured in low Mn2+ medium (< 0.1 µM Mn2+), but not in iron (Fe2+/Fe3+)‐limited medium, and was enhanced in the presence of human saliva or serum. mRNA analysis revealed that under low Mn2+ conditions, levels of scaCBA transcript (2.6 kb) were increased > 20‐fold. The Mn2+‐responsive transcriptional regulator of the sca operon was purified and characterized as a 215‐amino‐acid residue polypeptide, designated ScaR, with 26% identity to the Corynebacterium diphtheriae diphtheria toxin repressor (DtxR). Inactivation of scaR in S. gordonii DL1 (Challis) resulted in constitutive derepression of sca operon transcription. Expression of tpx, located immediately downstream of scaA and encoding a putative thiol peroxidase, was not subject to ScaR regulation. Purified ScaR protein bound to the scaC promoter region in vitro in the presence of Mn2+ (Kd∼ 80 nM) and, to a lesser extent, in the presence of Ni2+ or Zn2+. The metalloregulator protein binding region was localized by DNA protection analysis to a 46 bp sequence encompassing the −35 and −10 promoter signatures. This sequence was well conserved within the promoters of corresponding virulence‐related permease operons in other streptococci. The results identify a new Mn2+‐sensing regulator of Mn2+ transport in streptococci, important for Mn2+ homeostasis during infection of the human host.

SuperHERO is a new high-resolution, Long Duration Balloon-capable, hard-x-ray (20-75 keV) focusing telescope for making novel astrophysics and heliophysics observations. The SuperHERO payload, currently in its proposal phase, is being developed jointly by the Astrophysics Office at NASA Marshall Space Flight Center and the Solar Physics Laboratory and the Wallops Flight Facility at NASA Goddard Space Flight Center. SuperHERO is a follow-on payload to the High Energy Replicated Optics to Explore the Sun (HEROES) balloon-borne telescope that recently flew from Fort Sumner, NM in September of 2013, and will utilize many of the same features. Significant enhancements to the HEROES payload will be made, including the addition of optics, novel solid-state multi-pixel CdTe detectors, integration of the Wallops Arc-Second Pointer and a significantly lighter gondola suitable for Long Duration Flights.

[1] One of the most distinct aurorae in the high-latitude dayside region occurs at the footprint of the cusp. The Spectrographic Imager SI-12 channel on the IMAGE spacecraft allows for long-duration observations of the proton aurora in this region and thus enables morphological and quantitative studies of the behavior of the proton aurora under different external solar wind conditions. Here we extend an earlier study of the proton aurora in the cusp during northward interplanetary magnetic field (IMF) conditions [Frey et al., 2002] to southward IMF conditions. We find a very similar dependence of the cusp aurora's location in magnetic local time (MLT) on the IMF By component, with locations at prenoon for negative By and postnoon for positive By. We also confirm the previously established dependence of the proton aurora brightness on the solar wind dynamic pressure. However, for similar solar wind pressures the proton aurora is brighter for the southward IMF case than for the northward IMF case. The other major difference between southward and northward IMF conditions is the very strong dependence of the latitude location on the magnitude of the IMF Bz for southward IMF. We discuss both differences in terms of the location of the reconnection site at the magnetopause that is connected to the ionosphere along cusp magnetic field lines.

We report the F-FDG PET/CT appearance of abdominal actinomycosis in a 48-year-old immunocompetent woman with a history of laparoscopic cystojejunostomy for pancreatic pseudocyst previously. F-FDG PET/CT demonstrated multiple hypermetabolism in the liver, spleen, cystojejunostomy anastomosis, greater omentum, and umbilical region. Actinomycosis was verified by biopsy. Hepatosplenic actinomycosis secondary to cystojejunostomy is extremely rare and easily to be misdiagnosed. PET/CT is helpful for auxiliary diagnosis, guiding biopsy, and exploring the extent of the disease.

In order for a robot to co-exist and operate with humans, not only must the robot be safe for the humans but it must perform comfortable motions. In this research, we had humans and robots cross operating paths and focused on avoidance motions at the places where the two would collide had they been allowed to continue. At this time, we considered having only the robot avoid the collision by slowing and/or stopping. Evaluation experiments were conducted using computer graphics to clarify the affects that the distance between humans and robots and the acceleration of the robot.

Lignin-based anionic exchange resin was synthesized by modified alkali lignin after reaction with epichlorohydrin and triethylamine in the weak alkaline medium provided by pyridine in the organic medium of N,N-dimethylformamide (DMF). The influence of pyridine on synthesis process and yield of products were discussed. The product was characterized by FTIR spectroscopy analysis and the adsorbent capabilities for N from aqueous solution were also exploited. The factors that might influent the adsorption performance were investigated. An adsorbent dosage of 0.2g, adsorption time of 100min, pH of 4 and the initial concentration of nitrate concentration was 10mg/l were selected as optimum conditions.

Taking into account the multifunctional disorders and consequences of oncological diseases and their treatment, rehabilitation in oncology has many goals and is aimed at restoring the physical, emotional, social, role and cognitive functioning of the patient, as well as returning the patient to previous labor activity. The principles of rehabilitation measures vary considerably from country to country, depending on the social security system in which they are included. In most European countries and in theUnited States of America, rehabilitation activities are mainly carried out on an outpatient basis. Whereas inGermanythere is a unique system in which rehabilitation is performed mainly in a hospital environment. This article presents an overview of rehabilitation measures in oncology practice conducted in different countries.

The article discusses the arguments and changing interpretations of the political situation in England in the second half of the XVIII century found in the English historiography of XIX-XX centuries. The interpretation of the political situation of the second half of the XVIII century was changing significantly in the course of the XIX-XX centuries. The need to analyze the interpretations is due to the fact that the characteristics of the English Enlightenment were largely determined by special political conditions of that time.

In this paper, we propose a new architecture for managing data in a Ubiquitous Health Monitoring System (UHMS). The purpose of this architecture is to enhance the privacy of patients and furthermore to decongest the Health Monitoring Center (HMC) from the enormous amount of biomedical data generated by the users' wearable sensors. This is achieved by using personal agents that receive and manage the personal medical data of their owners. A component implementing the appropriate level of intelligence can be plugged-in into the personal agent and continuously analyze the raw health data. In case of an aberration detection the component may alert the HMC to initiate a more thorough examination of the possible emergency. Finally, we discuss how the personal agents can support privacy-preserving distributed computations.

The proton NMR line width and spin–lattice relaxation times for [N(CH3)4]2ZnCl4 single crystal were studied over a wide temperature range. Proton spin–lattice relaxation time measurements on [N(CH3)4]2ZnCl4 yielded a minimum, which were attributed to the effect of molecular tumbling. It seems obvious that the high-temperature minima of T1 is attributable to the tumbling motion of [N(CH3)4] ions, and that the T1 below 161 K is attributable to the same molecular motion which dominates at 210 K. Then, the T1 below 161 K undergoes a slow motion. The activation energies in phase VI and IV were determined to be 13.94 and 22.49 kJ/mol, respectively.

Preparing metal single-atom materials is currently attracting tremendous attention and remains a significant challenge. Herein, we report a novel core-shell strategy to synthesize single-atom materials. In this strategy, metal hydroxides or oxides are coated with polymers, followed by high-temperature pyrolysis and acid leaching, metal single atoms are anchored on the inner wall of hollow nitrogen-doped carbon (CN) materials. By changing metal precursors or polymers, we demonstrate the successful synthesis of different metal single atoms dispersed on CN materials (SA-M/CN, M = Fe, Co, Ni, Mn, FeCo, FeNi, etc.). Interestingly, the obtained SA-Fe/CN exhibits much higher catalytic activity for hydroxylation of benzene to phenol than Fe nanoparticles/CN (45% vs 5% benzene conversion). First-principle calculations further reveal that the high reactivity originates from the easier formation of activated oxygen species at the single Fe site. Our methodology provides a convenient route to prepare a variety of metal single-atom materials representing a new class of catalysts.

Interaction of leukocytes in flow with adherent leukocytes may contribute to their accumulation at sites of inflammation. Using L- selectin immobilized in a flow chamber, a model system that mimics presentation of L-selectin by adherent leukocytes, we characterize ligands for L-selectin on leukocytes and show that they mediate tethering and rolling in shear flow. We demonstrate the presence of L- selectin ligands on granulocytes, monocytes, and myeloid and lymphoid cell lines, and not on peripheral blood T lymphocytes. These ligands are calcium dependent, sensitive to protease and neuraminidase, and structurally distinct from previously described ligands for L-selectin on high endothelial venules (HEV). Differential sensitivity to O-sialo- glycoprotease provides evidence for ligand activity on both mucin-like and nonmucin-like structures. Transfection with fucosyltransferase induces expression of functional L-selectin ligands on both a lymphoid cell line and a nonhematopoietic cell line. L-selectin presented on adherent cells is also capable of supporting tethering and rolling interactions in physiologic shear flow. L-selectin ligands on leukocytes may be important in promoting leukocyte-leukocyte and subsequent leukocyte endothelial interactions in vivo, thereby enhancing leukocyte localization at sites of inflammation.

The ability to prove mathematically is one of the important abilities in learning mathematics. This study aims to determine students' mathematical proof ability. This type of research is a qualitative descriptive study, which involved 38 sixth semester students of the Mathematics Education Department, Tarbiyah and Teacher Training College, Alauddin Makassar State Islamic University with 3 of them being interview subjects. The instruments and data collection techniques used were researchers using diagnostic tests and interview guides. The analysis techniques used are data reduction, display data, and conclusion drawing / verification. The result of this research is that the students' mathematical proving ability in working on the questions is not optimal. In the indicator of the ability to construct evidence, students are less able to make connections between known facts and the elements to be proven. Furthermore, on the indicator of the ability to read a proof, students are less able to use definitions as a basis for providing arguments.

We studied the problem of finding a subspace of Web pages that is contextually consistent for co-occurrence analysis. We looked at blogs and proposed blogger-based co-occurrence analysis, which assumes that two items are relevant to each other if they appear in any of the blog entries posted by the same blogger. We show that (1) blogger-based analysis outperforms conventional page-based analysis in solving context-sensitive problems and that (2) analysis focused on bloggers forming a community yields better performance compared with that focused on isolated bloggers.

Ecological processes that control fungal distribution are not well understood because many fungi can persist in a wide variety of dissimilar habitats which are seldom sampled simultaneously. Geographic range size is reflective of species’ resource usage, and for plants and animals, there is a robust positive correlation between niche-breadth and range-size. It remains unknown whether this pattern is true for fungi. To investigate the fungal niche breadth–range size relationship we identified habitat specialists and generalists from two habitats (plant leaves and soil) and asked whether habitat specialization influenced fungal biogeography. We sampled fungi from the soil and phylloplane of tropical forests in Vanuatu and used DNA metabarcoding of the fungal ITS1 region to examine rarity, range size, and habitat connectivity. Fungal communities from the soil and phylloplane are spatially autocorrelated and the spatial distribution of individual fungal OTU are coupled between habitats. Habitat breadth (generalist fungi) did not result in larger range sizes but did correlate positively with occurrence frequency. Fungi that were frequently found were also found in high abundance, a common observation in similar studies of plants and animals. Fungal abundance-occupancy relationships differed by habitat and habitat-specificity. Soil specialists were found to be locally abundant but restricted geographically. In contrast, phylloplane generalists were found to be abundant over a large range in multiple habitats. These results are discussed in the context of differences between habitat characteristics, stability and spatial distribution. Identifying factors that drive spatial variation is key to understanding the mechanisms that maintain biodiversity in forests.

To reduce the energy consumption and improve the stability of distributed drive electric vehicles, a torque allocation strategy based on an economy and stability optimisation function (ESOF) and a fuzzy proportional-integral-derivative rule control (FPRC) strategy are proposed while considering motor efficiency, braking energy recovery and motor failure. First, the vehicle dynamics and motor equivalent models are established. Subsequently, a torque prediction model and fuzzy controller for the vehicle are designed to calculate the total desired torque and yaw moment, respectively. A torque optimisation function is established to minimise power losses in the electric motor and maximise braking energy recovery, and it is solved using an improved genetic algorithm. While satisfying vehicle driving constraints, the ESOF-based controller can effectively coordinate the operation of each motor in the high-efficiency range under driving and braking conditions. After one motor fault is detected, the ESOF-based controller is replaced with an FPRC-based controller to distribute the vehicle demand torque. A co-simulation platform integrating MATLAB/Simulink and CarSim is developed to verify the effectiveness of the proposed ESOF-based controller in the New European Driving Cycle (NEDC) and Federal Test Procedure 75 (FTP75) driving cycles. The effectiveness of the FPRC-based controller in step steering condition is verified using the co-simulation platform. The simulation results indicate that the vehicle economy and driving range of the ESOF-based controller improved compared with the results afforded by the typical torque distribution strategy based on the front–rear axle dynamic load ratio. The average efficiencies of the motors in the NEDC and FTP75 driving cycles increased by 2.94% and 2.4%, respectively. More importantly, the FPRC-based controller can more significantly improve the steering stability of a vehicle with motor failure compared with the ESOF-based controller.

Because of the long lead time between ordering equipment and commissioning, power-system planning has always catered explicitly for uncertainties. In the past, elaborate deterministic techniques have been used, but there are now doubts about whether the out-turn from such sophistication justifies the efforts required. Perhaps a more flexible, informal approach to both planning and uncertainty is the answer, e.g. to be able to alter course to take account of actual conditions; also, optimisation techniques might be changed. Unexpected power-system structures, reliability and loss levels, and also generation plant mixes, might well result, which are better for meeting actual requirements than those at present

The increase in fuel prices makes the use of essential oils as a natural bio-additive in diesel engines much in demand. This is because essential oils are believed to have good content to improve engine performance and reduce fuel consumption. In this research, essential oils used are citronella oil because they contain carboxylic compounds (-COOH) and clove oil which has the advantage to prevent corrosion. The aim is to improve engine performance and reduce fuel consumption can also prevent corrosion. This research was conducted by mixing citronella oil and clove oil with diesel fuel with a percentage of 1%, 0.5%, and 0.1% of the total volume. The diesel engine is operated with a loading variation of 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, and 2000 W at a constant engine speed of 1500 rpm. The variables measured and calculated in this experiment are power, torque, Brake Mean Effective Pressure (BMEP), Specific Fuel Consumption (SFC). The results showed that the addition of citronella oil and clove oil to diesel fuel with a percentage of 0.1%, 0.5%, and 1% significantly reduced fuel consumption by 14.6%, 12.9%, and 18.3%, respectively. The maximum fuel reduction from mixed oils is only 0.086 liters/hour at 1000W loads with 1% bio-additives content.

Small-scale purification of plasmid DNA is commonly used in molecular biology procedures. Several protocols for rapid isolation of DNA have previously been published (1,2). Several companies have also developed reliable miniprep kits that have become the method of choice for most laboratories when preparing plasmid DNA. However, even when using a kit, these miniprep processes can be laborious and time-consuming, particularly when large numbers of minipreps are performed in parallel. For multiple plasmid preparations, the rate-limiting step of miniprep protocols is resuspension of the cell pellet. The standard technique is to pellet multiple bacterial cell cultures in 1.5-mL microcentrifuge tubes for 30 s to 10 min, depending on the volume of culture pelleted. After centrifugation, the cells are resuspended by vortex mixing. Complete resuspension of cells before lysis is critical to achieve a good yield. However, this process often requires 20 s to several minutes to achieve complete resuspension. We have devised a rapid protocol to completely resuspend the cell pellet in only 3–4 s without any negative effect on the quantity and quality of plasmid DNA, irrespective of size. E. coli cells carrying plasmids of 3.0, 5.6 or 20 kb in size (pBluescript [Stratagene, La Jolla, CA, USA] plus Time of Cell Volume Scraping Centrifugation of Culture Vortex Rack

For much of the twentieth century, Americans had a love/hate relationship with France. While many admired its beauty, culture, refinement, and famed "joie de vivre," others thought of it as a dilapidated country populated by foul-smelling, mean-spirited anti-Americans driven by a keen desire to part tourists from their money. "We'll Always Have Paris" explores how both images came to flourish in the United States, often in the minds of the same people. Harvey Levenstein takes us back to the 1930s, when, despite the Great Depression, France continued to be the stomping ground of the social elite of the eastern seaboard. After World War II, wealthy and famous Americans returned to the country in droves, helping to revive its old image as a wellspring of sophisticated and sybaritic pleasures. At the same time, though, thanks in large part to Communist and Gaullist campaigns against U.S. power, a growing sensitivity to French anti-Americanism began to color tourists' experiences there, strengthening the negative images of the French that were already embedded in American culture. But as the century drew on, the traditional positive images were revived, as many Americans again developed an appreciation for France's cuisine, art, and urban and rustic charms. Levenstein, in his colorful, anecdotal style, digs into personal correspondence, journalism, and popular culture to shape a story of one nation's relationship to another, giving vivid play to Americans' changing response to such things as France's reputation for sexual freedom, "haute cuisine," high fashion, and racial tolerance. He puts this tumultuous coupling of France and the United States in historical perspective, arguing that while some in Congress say we may no longer have french fries, others, like Humphrey Bogart in "Casablanca," know they will always have Paris, and France, to enjoy and remember.

The electrospinning method coupled with a chemical reaction is employed to fabricate a TiO2/CdS composite fiber. The concentration of CdS can be changed by varying the amount of CdCl2 present as the crystal seed in the precursor sol. The DRUV-Vis spectra results show that the TiO2/CdS composite fiber absorbs both in the UV and visible regions. The results of TEM, XRD, PL, CLSM and Raman spectra also confirm the formation of CdS in TiO2 fibers.

The present study concern on mycologic and immunochemical data obtained from two samples of a fungus considered as belonging to the species Paracoccidioides cerebriformis described by Moore in 1935, and maintained since then on Sabouraud's agar in the mycology collection of the Instituto de Medicina Tropical de São Paulo. After 60 years, the samples exhibited the same characteristics described by MOORE (1935). However, experimental lesions did not resulted in guinea-pigs inoculated intratesticularly. The dominant antigen in Paracoccidioides brasiliensis, 43 kDa glicoprotein (gp43), could not be demonstrated by SDS PAGE and Western blotting. Immunoelectrophoresis did not demonstrated the E arch of cathodic migration using a policlonal anti gp43 serum. According to these findings, it is concluded that the fungus described by MOORE (1935) as P. cerebriformis does not belong to the genus Paracoccidioides. Paracoccidioidomycosis should therefore be considered as resulting from infection by a single species, Paracoccidioides brasiliensis (Splendore, 1912) as asserted by ALMEIDA (1930). Further studies, through molecular biology methods, could identify the mentioned fungus.

Bronchial hyperresponsiveness (BHR) is the most common clinical manifestation identified in asthmatic patients, and intubation is the major factor that stimulates the airway of patients receiving general anesthetic. In the present study, nitric oxide synthase 1 (NOS1) was identified as a target gene of micro (mi)R‑146a using in silico analysis and luciferase assay. Furthermore, the regulatory role of miR‑146a was demonstrated by the observation that the NOS1 expression level in pulmonary artery smooth muscle cells (PASMCs) transfected with miR‑146a mimics was significantly downregulated and the NOS1 expression level in PASMCs transfected with miR‑146a inhibitors was significantly upregulated. Additionally, it was identified that a polymorphism in pri‑miR‑146 interfered with mature processing and reduced the quantity of mature miRNA. To assess the association between the polymorphism and the development of BHR, 563 patients with basic pulmonary diseases, such as asthma, emphysema or bronchitis were enrolled in the present study. Each participant received a general anesthetic and the development of BHR was evaluated. The miR‑146a rs2910164 polymorphism CC genotype was identified to be significantly associated with a decreased risk of BHR in response to intubation when compared with the GG or GC genotype (odds ratio, 0.38; confidence interval, 0.18‑0.78). These findings indicate that the miR‑146a rs2910164 polymorphism is associated with a decrease risk of BHR, and the CC genotype increased the level of NOS1 expression, which was physiologically inhibited by wild‑type miR‑146a.

The effect of stressors on biodiversity can vary in relation to the degree to which biological communities have adapted over evolutionary time. We compared the responses of functional features of stream insect communities along chronic stress gradients with contrasting time persistence. Water salinity and land use intensification were used as examples of natural (long-term persistent) and anthropogenic (short-term persistent) stressors, respectively. A new trait-based approach was applied to quantify functional diversity components and functional redundancy within the same multidimensional space, using metrics at the taxon and community levels. We found similar functional responses along natural and anthropogenic stress gradients. In both cases, the mean taxon functional richness and functional similarity between taxa increased with stress, whereas community functional richness and functional redundancy decreased. Despite the differences in evolutionary persistence, both chronic stressors act as strong nonrandom environmental filters, producing convergent functional responses. These results can improve our ability to predict functional effects of novel stressors at ecoloiical and evolutionary scales.

The methodology selected in the early days of industrial toxicology was simple (Table 1): it called for exposure of laboratory animals to graded doses of test substances for varying periods of time, and diligent recording of toxic signs, using clinical, biochemical and pathomorphological techniques. In order to avoid bias, no assumptions were permitted; instead, strict adherence to set protocols was required. Over the years, the toxicological models have been perfected, but the philosophy of testing has essentially remained unchanged. The first guidelines were made when few of the functional, biochemical and structural changes induced by chemicals were known. Most of the now familiar adverse responses, centrilobular hepatic necrosis, peroxisome proliferation, dying-back and delayed neuropathy, autoimmune reactions, teratogenic and mutagenic effects, to name only a few, remained to be discovered. With our much deeper knowledge of toxicological phenomena, we must now ask two important questions: (i) are the testing procedures developed in the forties still good enough today, and (ii) are they cost effective? In order to analyse these problems, the performance of repeated dose toxicity studies will be discussed (Table 2). Although the data generated are extensive-approximately 30 000 bits of information

It is my great honor to deliver a welcome speech as the Editor-in-Chief of Journal of Molecular Cell Biology (JMCB) and the Chair of JMCB Symposium 2019: The Legend of p53 vs. Cancer. Please allow me to borrow the logion ‘what’s past is prologue’ from the great English playwright William Shakespeare as follows: What’s knowledge is prologue. This phrase could be applied for the most famous p53. Since the TP53 gene was identified by Dr Levine and others (DeLeo et al., 1979; Kress et al., 1979; Lane and Crawford, 1979; Linzer and Levine, 1979), nearly a hundred thousand of papers about p53 so far have been published. At the early stage of p53 studies, researchers paid attention to its function in transcriptional regulation; later, researchers uncovered various non-transcription functions (Lu, 2017; Zhou et al., 2017). p53 not only functions in the physiological and pathological processes (El-Dahr et al., 2017; Tackmann and Zhang, 2017), but is also involved in the factitious biological processes such as generating iPS cells or gene editing by CRISPR/Cas9. Like the Swiss Army knife, p53 could play various roles during different biological processes. What’s knowledge is prologue. This phrase could be applied for the most complicated p53. In the beginning, the TP53 gene was regarded as an oncogene, but soon re-defined as a tumor suppressor. The TP53 gene has the highest mutation rate among genes identified in the human genome; previous work showed that various mutations of the TP53 gene existing in around 50% of tumor types result in the loss of its tumor suppressive function. However, a recent study reported that one particular mutation in the TP53 gene could generate super-tumor suppression (Mello et al., 2017). In addition, p53 could interact with different partners and then play opposite roles, as either tumor suppressor or oncogene. Just at the beginning of this year, one work uncovered the dark side of p53: wild-type p53 can promote the progression of liver cancer (Kim et al., 2019). The studies on p53 clearly demonstrate the complexity and randomicity of living systems. What’s knowledge is prologue. This phrase would not be limited to the research of p53. The knowledge as ‘islands’ locates in the unlimited ‘sea’ of the unknown. The more increasing the knowledge is, the more growing the related unknown area is. It is the challenge of the research, and it is the delight of the research! [Opening remarks at JMCB Symposium 2019, Hangzhou, China. May 10, 2019.]

This paper focuses on transnational education (TNE) and student academic identity development. In recent years many North-American universities opened branch campuses abroad. This phenomenon resulted in growing interest in TNE. However, for the most part, the body of research on TNE reflects the perspective of the home institution, which privileges focus on curriculum design and program administration. There is still need for studies from an ecological perspective. Arguably, more attention needs to be given to the lived experience of students negotiating disparate discourses and conflicting cultural value systems, especially in the Middle East. The author presents a case study of a university on a mega-campus in Doha, Qatar to explore students’ perceptions of their identity negotiation in a new complex social and symbolic space of a TNE campus. Discussing the findings of an exploratory research project, she asks what pedagogical practices can best help students to function between languages and cultures.

Brinjal (Solanum melongena L.; 2n = 24) belong to the Solanaceae family, are native to the South East Asian region and were first domesticated there over 4000 years ago. It is one of the most important vegetables worldwide. India ranks second in area and production of brinjal in the world after China. In India, it is grown in an area of about 0.68 million hectares with annual production of 12.70 million tonnes and productivity of 18.7 tonnes/ha. At National level West Bengal ranks first in area and production. Tripura ranks first in productivity (46.43 MT/HA). In Maharashtra brinjal is grown on 27.30 thousands hectares with total production of 5.61 lakh tonnes and productivity 20.55 MT/HA (Anonymous, 2015). The commercial varieties are susceptible to this disease and chemical control through treatment of soil is both cumbersome and uneconomical. Therefore, breeding varieties for bacterial wilt resistance combined with high yields and acceptable quality is the present day need. Hence, an attempt was made to screen the parental lines and their F1 crosses of brinjal for resistance to Ralstonia wilt.

The effects of equal channel angular pressing (ECAP), further heat treatment and rolling on the structure and room temperature mechanical properties of the commercial aluminum alloys 6061 (Al-0.9Mg-0.7Si) and 1560 (Al-6.5Mg-0.6Mn) were investigated. It has been shown that the strength of the alloys after ECAP is higher than that achieved after conventional processing. Prior ECAP solution treatment and post-ECAP ageing can additionally increase the strength of the 6061 alloy. Under optimal ageing conditions a yield strength (YS) of 434 MPa and am ultimate tensile strength (UTS) of 470 MPa were obtained for the alloy. Additional cold rolling leads to a YS and UTS of 475 and 500 MPa with 8% elongation. It was found that the post-ECAP isothermal rolling of the 1560 alloy resulted in the formation of a nano-fibred structure and a tensile strength (YS = 540 MPa and UTS = 635 MPa) that has never previously been observed in commercial non-heat treatable alloys.

Abstract 5/6 Nephrectomy (PNx) on rat and mouse mimics renal failure after loss of kidney function in human, and it has been widely used in CKD researches. However, existing methods for PNx model construction present high mortality of animals after modeling due to hemorrhage and infection in or after surgery. Here, we report a novel and highly efficient PNx modeling method to simulate conventional 5/6 nephrectomy, which significantly reduced the mortality of animals and simplified the modeling procedures. In this novel modeling method, we directly ligated the upper and lower poles of left kidney after removal the right kidney 1 week later (l-PNx), which leads to necrosis of ligated upper and lower poles of the kidney and mimics the conventional 5/6 nephrectomy (c-PNx). After modeling 4 and 12 weeks, the serum creatinine, BUN and proteinuria levels were strongly increased in both c-PNx and l-PNx model. Importantly, compared with the c-PNx, l-PNx model present more severe renal fibrosis estimated by Masson staining, IHC and western blotting. The results showed that the protein levels of α-SMA were significantly increased in the kidney of c-PNx and l-PNx models, but more increase was found in l-PNx model. It is noteworthy that, compared with c-PNx model, the survival rate of l-PNx model was markedly increased. In summary, we established a novel and efficient 5/6 nephrectomy model, which can mimic conventional 5/6 nephrectomy to construct a renal fibrosis and renal failure mouse model, that is conducive to mechanism and treatment researches of CKD.

This study addresses the casual relationship between urban growth patterns and environmental phenomena, which we have in Geographic Information Systems (GIS) as a powerful tool to support urban planning and decision-making. In this sense, an analysis of susceptibility to flooding of regions through GIS represents important information for the public sector, as support to the urban zoning process, delimitation of risk areas and for the allocation of public resources, with corrective and preventive purposes. Thus, this study aimed to determine areas susceptible to flooding in in the municipality of Juazeiro do Norte, Ceará, through geoprocessing techniques. For that purpose, data on slope, elevation, accumulated water flow, curve number, soil type and land use and occupation were used. The results indicated that Juazeiro do Norte is a city of medium susceptibility to flooding, corresponding to 69% of the municipality and compromising 17% in a high susceptibility. The urban area of the Tiradentes neighborhood deserves alert due to its greater potential for flooding, where 79.5% of its area is very vulnerable. The generated map serves as an instrument for managing and monitoring extreme water events that happen routinely in the city. It also signals the community and managers to take measures to prevent and minimize flooding.

The theory of compressive sampling involves making random linear projections of a signal. Provided signal is sparse in some basis, small number of such measurements preserves the information in the signal, with high probability. Following the success in signal reconstruction, compressive framework has recently proved useful in classification. In this paper, conventional random projection scheme is first extended to the image domain and the key notion of concentration of measure is studied. Findings are then employed to develop a 2D compressive classifier (2D-CC) for sparse images. Finally, theoretical results are validated within a realistic experimental framework.

Poly L-lactic acid (PLLA) is a popular biodegradable polymer that is used extensively for many biological applications. A limitation of using PLLA is the difficulty in forming the polymer in complex shapes and forms for applications that include drug delivery and tissue engineering. This study focuses on PLLA replication using hot embossing technology. In this study hot embossing process parameters were identified, replication quality was examined, and crystallinity of PLLA was analyzed. The replication quality of micropillars and microreservoirs was examined using optical microscopy and scanning electron microscopy, with good replication obtained using a hot embossing pressure of 18 MPa at a temperature of 85 degrees C and holding time of 120 s. The material properties were examined using differential scanning calorimetry and infrared spectroscopy that indicated no substantial crystallinity or structural changes during hot embossing of PLLA. The study presented in this article concludes with the assessment that hot embossing technology could be used as a viable micromanufacturing process for the fabrication of inexpensive PLLA-based microdevices, with possible applications to controlled drug delivery, growth factors pathways, or other therapeutic applications.

We report on experimental results from the heavy ion CT (IonCT) system based on the measurement of residual range distribution; this technique was first investigated by Zygmanski et al. (2000) for proton beams. Experiments were done on the spatial and density resolution phantom by using 4He and 12C beams accelerated up to 230 MeV/u and 400 MeV/u by the Heavy Ion Medical Accelerator in Chiba (HIMAC), installed in the National Institute of Radiological Sciences (NIRS) in Japan, with a high performance intensified charged coupled device (ICCD) camera. We show that rods with a diameter of 1 mm can be successfully reproduced using the 12C beam with this technique. We also show that the MCS blurring effect in the reconstructed image can be reduced for the heavier ion beam. The reduction in the background neutron noise from the phantom and/or collimator, by using the data obtained from the improvement of the optical detector system in 2007, is also shown.

Combining multiple smart materials into a single concept that effectively utilizes their unique capabilities can achieve performance beyond the individual limitations of its constituent materials. Previous work characterized the mechanisms of the Synergistic Smart Morphing Aileron (SSMA) concept, which combines the fast, conformal actuation of MacroFiber Composites (MFC) with the high specific work of Shape Memory Alloys (SMA). The aerodynamic benefits of the SSMA concept are identified by comparing the performance of the combined system with its constituent actuators for a representative airfoil. The optimized uncoupled performance of experimentally measured shapes in a 2D Navier-Stokes simulation showed 45% improvement in ability to affect the flow over a range of flight conditions. A geometrically nonlinear finite element code was then coupled with the flow simulation confirming improved performance under aerodynamic loads. Additionally, the SSMA demonstrated the ability to mitigate aeroelastic effects and flow separation near stall via novel reflex actuation. These results show a combined system with improved flow control beyond its constituent subsystems.

We simultaneously study the dynamics of the growth of errors and the question of the faithfulness of simulations of $N$-body systems. The errors are quantified through the numerical reversibility of small-$N$ spherical systems, and by comparing fixed-timestep runs with different stepsizes. The errors add randomly, before exponential divergence sets in, with exponentiation rate virtually independent of $N$, but scale saturating as $\sim 1/\sqrt{N}$, in line with theoretical estimates presented. In a third phase, the growth rate is initially driven by multiplicative enhancement of errors, as in the exponential stage. It is then qualitatively different for the phase space variables and mean field conserved quantities (energy and momentum); for the former, the errors grow systematically through phase mixing, for the latter they grow diffusively. For energy, the $N$-variation of the `relaxation time' of error growth follows the $N$-scaling of two-body relaxation. This is also true for angular momentum in the fixed stepsize runs, although the associated error threshold is higher and the relaxation time smaller. Due to shrinking saturation scales, the information loss associated with the exponential instability decreases with $N$ and the dynamical entropy vanishes at any finite resolution as $N \rightarrow \infty$. A distribution function depending on the integrals of motion in the smooth potential is decreasingly affected. In this sense there is convergence to the collisionless limit, despite the persistence of exponential instability on infinitesimal scales. Nevertheless, the slow $N$-variation in its saturation points to the slowness of the convergence.

BACKGROUND
There has been an enormous focus on the discovery and development of neuroprotective agents that might have clinical relevance after traumatic brain injury (TBI). Based on experimental facts, we studied administration of creatine to patients with TBI.
METHODS
A prospective, randomized, comparative, open-labeled pilot study of the possible neuroprotective effect of creatine was performed on 39 children and adolescents, aged between 1 to 18 years old, with TBI. The creatine was administered for 6 months, at a dose of 0.4 gr/kg in an oral suspension form every day. For categorical variables, we used the chi test to identify differences between controls and cases. Statistical significance was defined as a p value <0.05 and not statistically significant if p value >0.1.
RESULTS
The administration of creatine to children with TBI improved results in several parameters, including duration of post-traumatic amnesia (PTA), duration of intubation, intensive care unit (ICU) stay, disability, good recovery, self care, communication, locomotion, sociability, personality/behavior and neurophysical, and cognitive function. Significant improvement was recorded in the categories of Cognitive (p < 0.001), personality/behavior (p < 0.001), Self Care (p = 0.029), and communication (p = 0.018) aspects in all patients. No side effects were seen because of creatine administration.
CONCLUSION
Preliminary data suggest that the administration of creatine may be beneficial to patients with traumatic brain injury.

In this paper, we discuss a simplified boundary modeling for numerical simulation of complex real resonator devices by prior scattering analysis. Appropriate boundary conditions are a crucial factor for accurate simulation of resonator devices. We propose to analyze the scattering of propagating eigenmodes at the substrate-to-membrane anchor of the resonating structure and show that model simplification is feasible, provided that the backscattered energy at the anchor/substrate boundary is small and the contribution of energy tunneling by evanescent modes is negligible. Exemplarily, we analyze the model of a film bulk acoustic resonator (FBAR).

The aim of research was to study the milk productivity and milk quality of cows and the closest female ancestors of stud bulls with different genotypes of the chaperone protein gene (HSP70.1). The genotypes of a chaperone protein gene in stock of cattle were determined by PCR-RFLP. It was established that among cows of the Kholmogory breed of the Tatarstan type, the highest milk yields, mass fraction, and the amount of fat and protein in milk were in animals with the HSP70.1/CC genotype compared to the analogues of the HSP70.1/C-genotype. Whereas in the closest female ancestors of bulls of the Holstein black-motley breed, individuals with the HSP70.1/C- and HSP70.1/"- -" genotypes stood out favorably by milk yield and mass fraction of fat in the milk, respectively.

Heat-treated cultures (50 °C, 15 s) of mesophilic lactic acid bacteria, Lactococcus lactis, Lactobacillus casei, or Lactobacillus plantarum, were each added at a level of 1.25% as an adjunct to the starter in the manufacture of low-fat goat's milk cheese. This addition did not affect the cheesemaking process and the overall composition characteristics of the cheeses but led to an increase of free aminopeptidase activity and the amine nitrogen over the ripening period. This improved the flavor intensity and body characteristics of the cheeses. The ratio of hydrophobic to hydrophilic peptides of MW < 10 000 in the water-soluble fraction was lower in cheeses made with heat-shocked cells than in the control cheeses at 30 days of ripening. General acceptability of cheeses containing treated cells was greater than of the others, scoring low for bitter and acid taste.

espanolEl cafe es una de las bebidas mas consumidas en el mundo siendo apreciado por sus caracteristicas organolepticas y mas recientemente por su potencial efecto beneficioso en la salud humana. Se han descrito compuestos en el cafe que le confieren propiedades antioxidantes. La actividad antioxidante puede ser medida con diferentes test y el metodo de captura del radical DPPH es un metodo utilizado por numerosos autores que han ido realizando adaptaciones del mismo para evaluar diversos alimentos (frutas, zumos, cafe, verduras). El objetivo de este estudio es evaluar la capacidad antioxidante del cafe mediante una optimizacion del ensayo DPPH en condiciones normales de consumo, empleando tres tipos de cafetera (filtro, expreso e italiana), comparado con cafes de distintos origenes (Colombia, Kenia y Etiopia) y cafe descafeinado. Los resultados de la optimizacion del ensayo muestran valores de absorbancias inferiores (0,709) cuando la muestra es sometida a la etapa de centrifugacion (modificacion de Delgado-Andrade, 2005) respecto a aquellas que son sometidas solo a agitacion (1,609). Los datos de actividad antioxidante obtenidos muestran una elevada capacidad antioxidante con porcentajes de inhibicion superior a 50 % destacando el cafe Colombia, Etiopia y Kenia elaborados con cafetera de filtro con valores de 70,56%, 73,52% y 73,65% respectivamente. En conclusion, segun los resultados obtenidos, vemos la necesidad de adaptar los metodos establecidos de captura de radicales a las caracteristicas del alimento o producto evaluado para asegurar al 100% la actividad antioxidante del alimento. La actividad antioxidante de la bebida de cafe no varia en funcion de la procedencia del cafe ni del contenido de cafeina que presenta. Por otro lado, en nuestro estudio, solo observamos diferencias de actividad antioxidante del cafe referidas al tipo de cafetera, donde el cafe elaborado mediante la cafetera tipo expreso presenta menor actividad antioxidante (p EnglishCoffee is one of the most consumed beverages in the world, being appreciated for its organoleptic characteristics and more recently for its potential beneficial effects on human health.

The peak load is the maximum daily processing capacity requirement in a warehouse, and is an alternative criterion for the storage location assignment problem in warehousing management. This paper addresses the problem of minimising the peak load in a storage/retrieval system with shared storage policy based on duration-of-stay of unit loads. A mixed integer programming model is presented. Two heuristics are developed to solve the problem. Their performances on different criteria are compared by computational tests.

Hurricane Katrina forced thousands of children in and around New Orleans to cope with life-altering circumstances. The Kidcope, a checklist designed to assess coping in pediatric populations, has been used to evaluate children after disasters. Research has demonstrated the importance of considering the role of cultural factors in the development and use of coping strategies. The authors examined the factor structure and psychometric properties of the Kidcope on the basis of the responses of hurricane-exposed, African American, predominantly low income youth in New Orleans and surrounding areas. The results yielded a one-factor scale for the adolescent version and three factors for the child version. Future directions for use of the Kidcope with African Americans are discussed.

Gender segregation in baccalaureate degree fields declined rapidly in the first half of the period from 1971 to 2002; at the same time, women's representation among baccalaureate degree recipients increased most rapidly relative to men's. The desegregation of the early period resulted mainly from women's increased entry into business-related fields and declining proportions of women majoring in traditional fields such as education and English. Men did not contribute to integration by moving toward fields numerically dominated by women. Fixed-effects regression models suggest that feminization of fields discourages later cohorts of men from entering them, as predicted by the devaluation perspective. The stalling of desegregation came from a combination of men's disinclination to enter fields that are “too” filled with women, and the slowdown in women making less traditional choices.

The aim of the study is to assess the restoration of anatomical and functional integrity of the uterus and the blood flow in the uterine and ovarian vessels after laparoscopic and abdominal myomectomy. Material and methods . 58 patients aged 36.2 ± 5.9 year old with uterine myoma underwent myomectomy: 31 patients underwent laparoscopic myomectomy and 27 patients underwent abdominal myomectomy. The selection of surgical approach didn´t depend on the size, the number and localization of uterine myomas and the patient´s concomitant pathology. Postoperative assessment was performed on day 5 th –8 th after surgery and in 1 and 6 months after myomectomy. 3D ultrasound examination with color Doppler mapping was used to assess the structure of the uterine scars after myomectomy and the blood flow in the uterine and ovarian arteries. Results. No significant differences were found in the processes of reparation of the uterus and in the blood flow in the uterine and ovarian arteries after laparoscopic or abdominal myomectomy. The time, required for the patients´ reabilitation and for the total restoration of the uterine morphological structure was about 6 months and was similar in both groups. Conclusion. Restoration of the anatomical and functional uterine integrity and the blood flow in the uterine and ovarian arteries after myomectomy doesn´t depend on the surgical approach if myomectomy is performed by experienced surgeon after the correct assessment of the clinical situation.

Active preparations of tRNA and aminoacyl-tRNA synthetases have been isolated from exponentially growing cells of Mycobacterium smegmatis and Mycobacterium tuberculosis H37Rv. Though the aminoacyl-tRNA synthetases of older cells retain their activity, the tRNAs seem to undergo modification and show poorer activity. The mycobacterial enzyme preparations catalyse homologous and heterologous aminoacylation between tRNA from the two species (M. smegmatis and M. tuberculosis H37Rv) or from Escherichia coli, with equal efficiency; tRNA samples from eukaryotic cells (yeast and rat liver) do not serve as substrates for the mycobacterial synthetases. The analytical separation of the different amino acid specific tRNAs from M. smegmatis resembles the pattern found in other bacteria. Purification of valine- (three species) and methionine-specific tRNA (two species) to 70-80% purity has been accomplished by using column-chromatographic techniques. Of the two species of tRNAMet, one can be formylated in the presence of formyl tetrahydrofolate and the transformylase from mycobacteria.

The kinetics and the stereochemistry of the protonation-induced unimolecular isomerization of (S)-(+)-1-D(1)-3-(p-tolyl)butane have been investigated in the gas phase in the 100-160 degrees C range. The process leads to the almost exclusive formation of the relevant meta isomer with complete racemization and partial 1,2-H shift in the migrating sec-butyl group. These results, together with the relevant activation parameters, point to the occurrence of low-energy, tightly bound isomeric sec-butyl cation/toluene complexes of defined structure and stability along the isomerization coordinate. The existence and the eta(1)-type structure of these low-energy intermediate species are confirmed by ab initio calculations on closely related systems at the MP2(full)/6-311++G**//HF/6-31+G** level of theory. Their role in the relevant energy surface clearly emerges from the comparison of the present results with those concerning sec-butylation of toluene carried out under comparable experimental conditions.

Amidase antibody 312d6, obtained against the sulfonamide hapten 4 a that mimics the transition state for hydrolysis of a distorted amide, accelerates the hydrolysis of the corresponding amides 1 a-3 a by a factor of 10(3) at pH 8. The mechanisms of both the uncatalyzed and antibody-catalyzed reactions were studied. Between pH 8 and 12 the uncatalyzed hydrolysis of N-toluoylindoles 1 a and 3 a shows a simple first-order dependence on [OH(-)], while hydrolysis of 3 a is zeroth-order in [OH(-)] below pH 8. The pH profile for hydrolysis of the corresponding tryptophan amide 2 a is more complex due to the dissociation of the zwitterion into an anion with pK(a) 9.74; hydrolysis of the zwitterionic and the anionic form of 2 a both show simple first-order dependence on [OH(-)]. Absence of (18)O exchange between H(2) (18)O/(18)OH(-) and the substrate, a normal SKIE for both 1 a (k(H)/k(D)=1.12) and 3 a (k(H)/k(D)=1.24) and the value of the Hammett constant rho for hydrolysis of p-substituted amides 3 a-e are consistent with an ester-like mechanism in which formation of the tetrahedral intermediate is rate-determining and the amine departs as anion. The 312d6-catalyzed hydrolysis of 3 a was studied between pH 7.5 and 9, and its independence of pH in this range indicates that water is the reacting nucleophile. Hydrolysis of 3 a is only partially inhibited by the sulfonamide hapten, and this indicates that non-specific catalysis by the protein accompanies the specific process. Only the nonspecific process is observed in the hydrolysis of amides 3 with para substituents other than methyl. Binding studies on the corresponding series of p-substituted sulfonamides 5 a-e confirm the high specificity of antibody 312d6 for p-methyl substituted substrates.

Rectal prolapse is associated with debilitating symptoms and leads to both functional impairment and anatomic distortion. Symptoms include rectal bulge, mucous drainage, bleeding, incontinence, constipation, tenesmus, as well as discomfort, pressure, and pain. The only cure is surgical. The optimal surgical repair is not yet defined though laparoscopic rectopexy with mesh is emerging as a more durable approach. The chosen approach should be individually tailored, taking into account factors such as presence of pelvic floor defects and coexistence of vaginal prolapse, severe constipation, surgical fitness, and whether the patient has had a previous prolapse procedure. Consideration of a multidisciplinary approach is critical in patients with concomitant vaginal prolapse. Surgeons must weigh their familiarity with each approach and should have in their armamentarium both perineal and abdominal approaches. Previous barriers to abdominal procedures, such as age and comorbidities, are waning as minimally invasive approaches have gained acceptance. Laparoscopic ventral rectopexy is one such approach offering relatively low morbidity, low recurrence rates, and good functional improvement. However, proficiency with this procedure may require advanced training. Robotic rectopexy is another burgeoning approach which facilitates suturing in the pelvis. Successful rectal prolapse surgeries improve function and have low recurrence rates, though it is important to note that correcting the prolapse does not assure functional improvement.

Defects in the EUV mask blank are one of the largest hurdles to achieving manufacturing readiness of EUV masks. For defect-free masks, the obvious approach is to order blanks that do not have defects or to shift the pattern so that remaining defects do not create a printed defect on wafer. The approach during development should be different. At this learning phase, it is wise to study the defects as they occur naturally on the EUV mask blank. This paper outlines a comprehensive approach to building a mask specifically to showcase the native defects so that they can be studied and repairs can be attempted. The method applied to mask build, defect inspection and characterization will be reviewed in detail. Printability of the mask defects of interest are characterized using both wafer printing and EUV microscope data. Repairs are attempted and characterized. In the end, the impact of native defects is discussed along with the viability of various repair methods.

The purpose of this talk is to initially provide an over-view of classical approaches used in bacterial identification, microbial forensics and biodetection. There will then be a brief discussion of bacterial biochemistry and taxonomy. This will be followed by recent examples of morphological (electron microscopy) and analytical chemical (mass spectrometry) bacterial characterization from our own research. This will lay down a framework for considerations in the use of spectroscopy (which is more developmental in nature) to provide equivalent or alternative information.

Background: Osteoporosis (OP) is one of the most common metabolic diseases, characterized by low bone mass and abnormal bone microarchitecture leading to the development of fractures and subsequent disability. Disruption of bone remodeling by osteoporosis results in an imbalance between bone formation by osteoblasts and resorption by osteoclasts. Aims: This study was aimed to investigate relationship between vitamin D3, calcium and PTH, with estimating their effects on osteoporosis in women and the benefits in diagnosis. Materials and method: In this study, 50women who were referred to DEXA unit in Al-Karama Teaching Hospital to diagnosed with Osteoporosis. They were compared with 40 healthy individuals who did not have any clinical symptoms. Blood samples were used after separating them by a centrifuge for the purpose of examining levels of vital indicators were detected by Enzyme linked immunosorbent assay (ELISA). Results: The results of the current study showed a decrease in the level of Vitamin D3 and calcium, increasing in the levels of Parathyroid hormone, with significant differences between the study groups at P≤0.0001 compared to the control group.

Objectives: The aim of the study was to know the sero-plevalence of Herpes Simplex Virus (HSV) infection in pregnant women attending a university hospital in Sudan. Methods: All pregnant women who came for delivery by lower segment caesarean section (LSCS) in National ribat teaching hospital between May and November 2011 were enrolled in this study. Their blood was tested for HSV IgG & IgM immunoglobulin. Their vulvas were examined for eruptions and ulcers and when those were found surface swabs were taken for isolation of organisms including syphilis. Their blood was also tested for HIV and syphilis. Results: One hundred thirty pregnant women were included in the study and forty five women (34.6%) tested positive for the IgG of Herpes virus but none of them was positive for the IgM test. Fourteen women had genital rashes/ulcers and nine of them tested positive for IgG but not IgM. Eleven women had lip ulcers or blisters and five of them tested positive for herpes. Conclusion: Acute infection during pregnancy was not documented in this study population and probably women develop immunity to herpes virus early in their reproductive life. Genital rashes and ulcers were not associated with active herpes infection.

Extraction of maximum power from PV (Photovoltaic) cell is necessary to make the PV system efficient. Maximum power can be achieved by operating the system at MPP (Maximum Power Point) (taking the operating point of PV panel to MPP) and for this purpose MPPT (Maximum Power Point Trackers) are used. There are many tracking algorithms/methods used by these trackers which includes incremental conductance, constant voltage method, constant current method, short circuit current method, PAO (Perturb and Observe) method, and open circuit voltage method but PAO is the mostly used algorithm because it is simple and easy to implement. PAO algorithm has some drawbacks, one is low tracking speed under rapid changing weather conditions and second is oscillations of PV systems operating point around MPP. Little improvement is achieved in past papers regarding these issues. In this paper, a new method named “Decrease and Fix” method is successfully introduced as improvement in PAO algorithm to overcome these issues of tracking speed and oscillations. Decrease and fix method is the first successful attempt with PAO algorithm for stability achievement and speeding up of tracking process in photovoltaic system. Complete standalone photovoltaic system’s model with improved perturb and observe algorithm is simulated in MATLAB Simulink.

The Rayleigh scattering coefficient within plastic optical fiber (POF), which is also called turbidity, has been investigated and parameters affecting the level of turbidity have been located and discussed. The Rayleigh attenuation model has been built on turbidity and has been verified by comparing with published data. Disparities between the model and published data have been discussed. The Rayleigh backscattering model based on turbidity and fractional recapture coefficient within the fiber has been built and the dependence of the total backscattered optical power on wavelength has been discussed.

The development of pesticides is a constant in the agricultural sector in order to offer products less aggressive to the environment and new active ingredients, preventing the emergence of resistance. The alternative study to fungicides used for seed treatment has the essential oils field for prospecting. This research aimed to evaluate the effects of essential oils from leaves of C. citriodora and E. camaldulensis in maize seed variety AL Bandeirante, from different locations. The physiological and sanitary quality of the seeds were evaluated when treated samples using the oils individually, equal mixture of these oils and treatment with a commercial antifungal. It was observed that the treatment with the oils C. citriodora , E. camaldulensis and the mixture of oils did not affect the immediate germination of seeds Avare. In the batch Bernardino de Campos, treatment with C. citriodora was harmful and E. camualdulensis , although not statistically differ from the others, decreased germination which would prevent its use as seed, according to the standard regulated by the Ministry of Agriculture, Livestock and Supply (MAPA), 85%. The E. camaldulensis oil showed phytotoxic effect decreasing the length of seedlings, acetone used as a solvent had no effect on germination but showed phytotoxic effect after accelerated aging. The application of oils alone was able to reduce the incidence of fungi of the genus Penicillium and Fusarium, Aspergillus but the behavior was similar to commercial antifungal, showing no effect when compared to the control treatment.
