The HSC resides in the BM and interacts with a highly organized microenvironment comprised of stromal cells, osteoblasts, osteoclasts and an extracellular matrix rich in fibronectin, collagens and various proteoglycans. , These BM cells secrete different regulatory soluble signals, including cytokines, chemokines and growth factors that regulate trafficking as well as self-renewal, proliferation, and differentiation of HSC. Previous reports have shown that the BM niche confers protection to hematologic malignancies and serves as support for epithelial metastasis. , , In fact, the interaction of leukemia cells with the BM stroma has been proposed as a mechanism for chemotherapy resistance. .

Model 1 accurately matches our data for the kinetics of the P × B (−RDF) and L × R (+RDF) reactions on plasmid substrates (Figure 4E). The model also has an excellent fit to the experimentally determined product levels after 3 h recombination reactions at a wide range of integrase and RDF concentrations (compare Figure 4A and B with C and D).

Confocal microscopy analysis showed a time-dependent internalization of fluorescently-labeled DiO-L-PDNPs by differentiated SH-SY5Y after 4, 24, and 72 h of incubation, while no significant internalization was present after 30 min of treatment (2D images shown in Figure 3a, 3D rendering shown in Figure S5). Flow cytometry analysis of cells incubated with DiO-L-PDNPs confirmed these data (Figures 3b and S6), with the relative fluorescence level of cells treated for 30 min being not statistically different (p > 0.05) from control cells; instead, cultures treated for 4, 24, and 72 h showed cell populations shifted toward statistically significant (p < 0.001) higher fluorescence values (Figure 3b). In particular, we found 16.69 ± 1.42% of fluorescence-positive cells after 4 h of treatment with DiO-L-PDNPs, 24.83 ± 3.09% after 24 h, and 58.60 ± 3.60% after 72 h. SEM observation of cells treated for 72 h with L-PDNPs showed also the presence of particles associated with the external surface of the cell membrane (Figure 3c).

The power is often the limiting factor, as the modern society is being highly dependent on battery sources for ultra-low power electronic devices. This leads to the tedious task of disposing and replacing large numbers of batteries that cause environmental pollution. Ambient EM energy harvesting (EH) offers a green and sustainable approach to this problem. This is a promising solution to provide a sustainable energy source to meet future demands of low power electronic systems. We are surrounded by EM energy in all frequency ranges. If we can capture and convert them into usable energy, we can use it to power many electronics that would help to address the energy challenges we are facing right now. To date, numerous approaches have been investigated for collecting such freely available EM radiation energy1–17. Among them, some of the research groups proposed and experimentally demonstrated mechanically flexible1,7, strongly polarization independent2,6,14,16, near unity4,5,14, and broadband absorbers1,2,4–7,12,14,16. However, the aforementioned propose structures can only work within a limited frequency band, which limits their practical applications. Karampour et al.6 and Alam et al.9 proposed and numerically investigated EM wave absorbers which can operate in the broadband IR region. Although, the structures show ultra-wideband and polarization-insensitive behavior, however their angular stability is quite low (incident angle \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\uptheta \le 35$$\end{document}θ≤35°), which causes practical limitations. Pala et al. experimentally investigated a prototype of angle insensitive, omnidirectional and broadband metasurface absorber based on two-dimensional periodic arrays of multi-resonant crossed trapezoidal Mie resonators3. At shorter wavelengths, the device can achieve a strong and broadband absorption, whereas at longer wavelengths, it exhibits quite low and narrowband absorption spectrum. Sun et al. proposed, fabricated, and experimentally demonstrated a cost effective wafer scale broadband THz absorber based on vertically aligned carbon nanotube (VACNT) arrays8. This is, however, challenging to obtain optimum parameters (volume fraction and alignment factor) practically due to the difficulties of controlling each parameters accurately throughout the fabrication process. Lv et al. demonstrated experimentally a broadband THz absorber based on engineered subwavelength surface relief grating structure11. Despite being polarization insensitive up to 60°, the structure suffers from uniform and smooth absorption spectrum and can only absorb EM waves in a narrow bandwidth over the THz regime. Yuan et al. have demonstrated a new type THz absorber based on antireflection techniques into doped silicon13. This structure can achieve high and broadband absorption, however, it shows some parametric deviations between measured results and simulated results due to the fabrication imperfection. The delicate differences in lithography process make deviations on such structure parameters. Zhu et al. numerically demonstrated a hybrid nano-antenna for IR and visible energy harvesting applications15. Although the proposed absorber can achieve strong and broadband absorption at normal incidence, however, it shows slightly weak absorption performance under different polarization angles. The average absorption decreases slightly with the increase in polarization angle due to structural asymmetry in some directions. Xiao et al.7, Haque et al.10, and Wu et al.17 also demonstrated ultra-wideband THz EM wave absorbers. Despite their strong and broadband performance, the structures suffer from fabrication difficulties in the lithography process due to their complicated nanostructure layout and several process steps. Therefore, a straightforward design strategy for new kind of structures is of great interest in order to overcome the limits of the aforementioned existing structures. Ultrathin wideband absorber with freely tunable operating frequencies across a wide frequency range, including the IR, visible, and UV–visible domains have yet to be investigated.

Biorąc pod uwagę potencjalny udział alergenowo swoistych limfocytów T, w patofizjologii FPIES oraz w mechanizmie powstawania odczynów podczas wykonywania ATP, metoda ta wydaje się być obiecującym narzędziem diagnostycznym. Istnieją pojedyncze badania, które oceniają przydatność testów w diagnostyce FPIES [28, 31]. Określają one swoistość ATP na poziomie 71-86%. Jednak z powodu sprzecznych danych dotyczących przydatności ATP w identyfikacji pokarmów wyzwalających FPIES, aktualnie nie ma zaleceń co do ich rutynowego wykonywania [1, 25].

Le cancer du sein chez l'homme est une maladie rare. Sa prévalence est d'un pour 100000 individus et il représente moins de 1% des cancers du sein et moins de 1% de l'ensemble des néoplasies masculines [1, 2]. L'incidence de cette pathologie semble relativement stable en Europe , mais Giordano et al montrent une augmentation de 26% entre 1973 et 1998 aux Etats Unis . L’âge moyen lors du diagnostic varie entre 63 et 71 ans ce qui correspond à cinq ans de plus par rapport à l’âge de découverte du cancer du sein chez la femme avec des extrêmes allant de 5 à 93 ans [1, 3, 4]. Sa distribution est unimodale. Dans notre série l’âge dépasse 50 ans avec des extrêmes de 56 et 79 ans. L'étiopathogénie du cancer du sein chez l'homme reste obscure, cependant de nombreux facteurs de risques semblent pouvoir être incriminés. L´obésité par aromatisation des androgènes et la cirrhose éthylique par l´élévation de sex steroid binding globulin provoquent un état d′hyperoestrogènie . Les anomalies testiculaires comme l'ectopie testiculaire, l'orchite, l'orchidectomie, les hernies inguinales congénitales et la stérilité sont des facteurs associés à un risque élevé de cancer du sein. Les seins ombiliqués, les antécédents de traumatisme mammaire et la transsexualité (incluant la castration chirurgicale et chimique) semblent impliqués [5–7]. L'hypogonadisme, présent dans le syndrome de Klinefelter, fait de lui un facteur de risque classiquement admis (risque relatif de 20 à 50 fois par rapport à un homme sans anomalies génétiques) mais cette prédisposition serait expliquée aussi par l'apport exogène de la testostérone, transformée en ‘strogène dans le tissu adipeux périphérique .

Each season, recruitment began when influenza activity was detected in the community and usually continued for 12–15 weeks. Symptom eligibility criteria varied by season but included fever/feverishness or cough during most seasons. We retroactively standardized symptom eligibility criteria to only require cough as a symptom. Individuals with illness duration >7 days or presenting in an inpatient (hospital) setting were excluded. After obtaining informed consent, a mid-turbinate swab was obtained for influenza detection. RT-PCR was performed using CDC primers and probes to identify influenza cases, including type and subtype.

As described above, in PCA large amount of spectral data is expressed by independent variables called eigenvectors, factors, or principal components and their scaling constants, scores. Scores of factors are often used as parameters to achieve objective discrimination. As mentioned earlier in Section 4, analysis was carried out in two different approaches: (1) unsupervised analysis, (2) supervised analysis. We have successfully tested these approaches in our earlier Raman spectroscopic studies of cervix, oral, and breast cancers [14, 15, 20, 22, 24, 31, 33].

The primary pain outcome was that of participants achieving at least 50% pain relief over four to six hours after study drug administration. This outcome has been used for over 20 years, validated several times as sensitively discriminating between analgesics of different efficacy, and is of value in postoperative pain [10, 29] and women with dysmenorrhoea .

Galectins (Gals) belong to members of ß-galactoside-binding lectins, which can be localized in extracellular spaces and in cellular components such as cell membrane, cytoplasm, and nucleus (89). They are implicated in cell-to-cell interactions, cell–extracellular matrix interactions, receptor crosslinking or lattice formation, intracellular signaling, and posttranscriptional splicing (90). Gal-3 has antiapoptotic effects, unlike most members of the galectin family (91). Gal-3 expression has been observed in the epithelium of corpus and cauda epididymis but not in initial segment and caput epididymis, suggesting that Gal-3 participates in maturation and storage of rat sperm (92). Previously, Gal-3-binding protein has been observed in bovine epidydimal fluid (57) and shown to participate in sperm motility, semen liquefaction, and angiogenesis in the female reproductive tract (93).

COVID-19 vormde een aanleiding, maar het ligt voor de hand dat de extra instrumenten, metingen en netwerken die tijdens de uitvoering van deze brede gezondheidsmonitor ontstaan, niet alleen ten goede zullen komen aan de GOR-taak in de toekomst, maar ook aan de reguliere gezondheidsmonitoring. Ook deze crisis legt immers bestaande gezondheidsrisico’s en kwetsbaarheden bloot die ook los van deze crisis aandacht verdienen van beleidsmakers en professionals.

First, we calculated municipal-level mortality rates and descriptive statistics for age and socioeconomic characteristics for the first and last period of the follow-up. We then estimated empty models (model 0) for the first and the last period, and obtained predictions of municipality-specific effects (empirical Bayes means of random effects). These estimates are presented in caterpillar plots as hazard ratios (HR) with the average hazard over municipalities as a reference to visually examine the overall change in mortality variation between municipalities before adjusting for any individual-level variables. Second, we present MHRs for empty (model 0), and age-adjusted (model 1) models, and a model further adjusted for socioeconomic characteristics (model 2) for each of the ten periods to investigate the extent to which changes in area variation were explained by changes in municipality age and socioeconomic structures. Thereafter, to examine whether trends varied by age, we estimated MHRs separately for mortality at ages 30–49, 50–69 and 70 and over. Age was adjusted in five-year groups within these categories. We repeated these models for internal and external causes, and finally included both age and all individual socioeconomic characteristics simultaneously (model 2). In the cause specific analysis persons dying of another cause were censored at their time of death. We present MHRs by cause of death adjusted for age (model 1) and for all individual-level variables (model 2) for those aged 30–49 and 50–69 years since, as we show below, variation is highest among these categories. MHRs by cause of death from models 1 and 2 for the age category 70 and over are presented in the Appendix (Table A1).

A importância do dentifrício fluoretado para o declínio da cárie dentária ocorrido no Brasil tem diminuído o impacto da fluoretação da água na redução de cárie, como já ocorrido em outros países. Com efeito, Pereira et al 26 (2000) acompanharam as mudanças da prevalência de cárie dentária em escolares de dois municípios de 1991 a 1997, um com água fluoretada (Piracicaba, SP) e outro sem fluoretação (Iracemápolis, SP). Em 1991, a diferença de prevalência de cárie era 50,0% menor em Piracicaba do que em Iracemápolis. No entanto, essa porcentagem foi gradativamente se reduzindo com o passar do tempo até chegar a aproximadamente 30,0% em 1997. Essa diferença poderia ter sido ainda menor, caso a prevalência de cárie no município de Piracicaba não estivesse também em declínio.

This study will focus on memory integration, an important sub-process or operation underlying episodic memory. Memory integration is a process by which temporally disparate, related or partially overlapping episodes are thought to become interconnected and potentially stored as overlapping neural representations (Schlichting and Preston, 2015; Backus et al., 2016; Koster et al., 2018). For instance, if one observes a woman entering a house on Monday, and a man entering the same house on Tuesday, the memory traces for this woman and man may become linked. This characteristic of memory has also been referred to as generalization (Kumaran and McClelland, 2012) and inferential memory (Cox et al., 2021)1. As such, memory integration supports flexible extraction of new information from memory (Zeithamova et al., 2012; Schlichting et al., 2014), and may underlie the formation of generalized knowledge (van Kesteren et al., 2016), and could therefore be related to semantic knowledge. Importantly, previous research indicates that some forms of memory integration can also reduce memory interference and competition, and thereby increase retention and prevent forgetting (Horton and Wiley, 1967; Moeser, 1977; Anderson and McCulloch, 1999; Konkle et al., 2010; Chanales et al., 2019). For instance, Anderson and McCulloch (1999) found reductions in retrieval-induced forgetting when interconnections were formed across list items during encoding, whether spontaneously adopted or instructed, whereas Postman (1964) observed that conditions that promoted integration across overlapping items in sequentially learned paired-associate lists benefited learning and reduced interference. Integration has further been suggested as a mechanism to avoid the trade-off between encoding and retrieval states, predicted by computational modeling (O’Reilly and McClelland, 1994), that would lead to conflicts between encoding and retrieval processes whenever current experience overlaps with past memories (Richter et al., 2016). This study proceeds from the information accumulation perspective of cognitive aging (see Qiu and Johns, 2020), and conjectures that the increased number of stored memory traces across life may lead to increased interference between similar stored traces (cf., Konkle et al., 2010), as well as more overlap between stored information and new information to be encoded, i.e., proactive interference. We hypothesize that this increased interference may drive an adaptive shift toward higher reliance on memory integration across the lifespan, as one route to reducing interference-related forgetting caused by an accumulation of memories across life. Thus, we reason that the absence of debilitating memory impairment due to interference-related forgetting in midlife, despite substantial accumulation of memory traces, may be accomplished or facilitated by increased integration, which in turn may be observable as a higher performance on test of memory integration in middle-aged adults compared to young. This is the main idea that the current study set out to test. As some previous studies have indicated a potential trade-off between memory integration and the discrimination of details from integrated memory traces (Sweegers and Talamini, 2014; van Kesteren et al., 2016; Tompary and Davachi, 2017), we further wanted to test whether previously observed age-related reductions in memory discrimination in midlife (Stark et al., 2013; Nauer et al., 2020; Güsten et al., 2021) are associated with increased reliance on integrative memory processing in midlife. To our knowledge, memory integration has not been specifically studied in midlife before, although older adults above age 60 have been shown to demonstrate impairment when compared to young (Carpenter and Schacter, 2018). Furthermore, substantial individual differences in integration performance and use of integrative encoding strategies can be found even within samples of younger adults (Anderson and McCulloch, 1999; Schlichting et al., 2014; Varga et al., 2019; Yu et al., 2020).

Los departamentos donde más se registra este tipo de resistencia, son aquellos donde históricamente se ha presentado el mayor número de casos de tuberculosis y farmacorresistencia del país; estos son Antioquia, Valle y Atlántico 5,8. Sin embargo, cada año se van sumando casos de otras entidades territoriales, lo cual puede deberse a procesos migratorios internos de la población, deficiencias en las medidas básicas de aislamiento y control de infecciones, debilidades en los estudios de contactos de los casos diagnosticados y las actividades de seguimiento al tratamiento por parte de los programas de tuberculosis, así como a la presencia de factores determinantes sociales, como la pobreza y el hacinamiento, entre otros 9,10.

To determine whether deficiency in tgfb1a or tgfb3 would lead to a similarly prolonged inflammation, we assessed numbers of neutrophils, macrophages and levels of il1b expression after perturbation of tgfb1a and tgfb3 at 48 hpl. To visualise macrophages in the injury site, we used the mpeg1:GFP transgenic line. We did not find any changes in macrophage numbers after injection of haCRs to tgfb1a or tgfb3 in lesioned animals, compared to lesioned controls (Fig 3A and 3B), indicating that these genes are not necessary for macrophages to populate the injury site.

Impaired microbicidal activity of neutrophils from PWCF. (A) Phagocytosis of FITC labelled S. aureus was assessed by flow cytometry and expressed as mean fluorescence intensity (MFI). Healthy control (HC) and neutrophils of PWCF (Phe508del single copy) demonstrated equal levels of phagocytosis (n = 6 donors per group, paired t test). (B) Killing of S. aureus (0.5 x 107 CFU/ml) by HC neutrophils was compared to CF cells donated by PWCF homozygous for the Phe508del mutation Killing rates between HC and CF neutrophils were significantly different (p = 0.0006) and reduced at each time point (n = 7 subjects per group, linear mixed effects model with post-hoc Holm-Šídák test).

As for the characteristics of the area that help understand the community identity, the study participants state that the territory provides them with water and very good soil, as it is a moorland area. However, the geographic isolation, deficiencies in public transportation, political-administrative division between two municipalities (El Cerrito and Palmira), limited access to basic services, and the limited government institution presence converge as factors of social determination of adolescent pregnancy. Perceptions about the community, institutional framework, and family are that they act as negative local social forces by repressing young people’s freedom to be informed and the right to exercise pleasurable sexual activity. As a result, young people seek to educate themselves or get help from other young people who are their social peers.“Parents don’t tell you about it [sexual activity]. As parents don’t communicate any of this to us, we look for information elsewhere.” (Young participant, Interview JE2)

CircRNAs, a class of circular non-coding RNAs, play vital biological functions in many physiological processes. CircRNAs were extensively explored as diagnostic and predictive biomarkers for various diseases, including cancer, neurological disease, inflammatory bowel disease, skin diseases, and Alzheimer’s disease (Ye et al., 2019; Zhang et al., 2019; Wang et al., 2020; Wu et al., 2020; Shengnan Li et al., 2021). To explore more sensitive biomarkers for DR screening, many samples extracted from different optical tissues, including retinal, vitreous humor, and serum, were studied (Gu et al., 2017; Jiang et al., 2020; He et al., 2020). He et al. studied the profile of circRNA expression in the vitreous humor of patients with proliferative diabetic retinopathy (PDR) (He et al., 2020). Gu et al. testified about many dysregulated circRNAs in serum from DR patients. hsa_circ_063981, hsa_circ_404457, hsa_circ_100750, hsa_circ_406918, hsa_circRNA_104387, hsa_circ_103410, and hsa_circ_100192 were significantly upregulated in DR patients compared to DM patients and healthy controls (Gu et al., 2017). Li et al. identified the profile of exosomal circRNAs in serum of PDR patients to explore their possible pro-angiogenic role (Xinsheng Li et al., 2021).

Oggi sappiamo che il virus del tabacco è in grado di stimolare, nelle piante, la sintesi di un ormone antinfiammatorio vegetale, l’acido salicilico (storicamente estratto da foglie e corteccia del genere Salix, salice), menzionato per la terapia antalgica già nell’antico Egitto del XVII secolo a.C. (divenuto, poi, aspirina Bayer – acido acetilsalicilico – nel 1899), che antagonizza la replicazione virale vegetale, effetto recentemente osservato anche con i Rhinovirus umani e che conferma la raccomandazione, applicata durante la seconda metà del Novecento, di utilizzare l’aspirina nella tiroidite subacuta (tipicamente associata a virus respiratori) dopo che, nel 1958, furono trattati con salicilato di sodio i primi 5 casi .

Many studies have demonstrated the effects of periodontitis on circulating ROS and oxidative stress. Studies have shown that dental pulp collected from teeth with periodontitis is inflamed under oxidative stress and presents increased levels of apoptosis and autophagy relative to normal dental pulp (Li et al., 2019). The pathogenesis of periodontitis is related to an imbalance between ROS and the antioxidant defense system. For example, levels of thiobarbituric acid reactive substances such as MDA, a biomarker commonly employed for lipid peroxidation, are elevated in erythrocytes, plasma, and local tissue homogenates of periodontitis patients (Tsai et al., 2005; Cherian et al., 2019). MDA exists at greater levels in the GCF and saliva of patients with periodontitis compared to in healthy controls. In addition, the GCF concentrations of MDA/4-hydroxyalkanes were 200- to 400-fold greater than that in saliva, suggesting that the amount of ROS activity in GCF was much higher (Akalin et al., 2007). Periodontal inflammation leads to an increase in systemic proinflammatory cytokines, such as 8-Hydroxydeoxyguanosine (8-OHdG), dityrosine, nitric oxide metabolites (NOx), and nitrotyrosine. Improving 8-OHdG, dityrosine, NOx, nitrotyrosine, and proinflammatory cytokine levels has been shown to prevent ligature-induced periodontitis and alleviate systemic oxidative stress (Tamaki et al., 2014). In a mouse model of gingival sulcus, locally inducing periodontitis with LPS and proteases elevated gingival hexanoyl-lysine (HEL) expression, leading to elevated HEL levels in the serum and increased 8-OHdG levels in kidney tissue (Tomofuji et al., 2011). 8-OHdG is formed when guanine in DNA undergoes oxidative damage by ROS and lipid peroxide (Kasai, 2002). 8-OHdG is generally accepted as a reliable indicator of tissue oxidative damage (Tomofuji et al., 2006).

Les caractéristiques des lésions (formes, dimensions, couleurs, contours) sont peu précisées. Cependant, il faut noter que dans certains cas, des qualificatifs imprécis et non adaptés aux pratiques médico-légales ont été utilisés, et dans d'autres cas, ces caractéristiques ont tout simplement été omises. Ceci rejoint l’étude menée par Grill et coll., qui soulignent le fait qu'un effort de la part des médecins devrait être fait afin qu'il soit systématiquement précisé sur les certificats les caractéristiques des lésions présentées par la victime.

Most studies have focused on the implant exterior’s design and size to find a solution for bacterial contamination, while limited focus has been placed on the interior of the implant. The microgap facilitates potential bacterial leakage into and out of the internal structure of the implant system . This is a common cause of inflammatory reactions at the marginal bone level, which can lead to ultimately marginal bone loss . Thus, with the existence of the implant−abutment interface, screw access holes play an important role in the success of screw-retained implant treatment and should not be considered insignificant or neglected.

Soluția de sulfat de condroitină/amestec hialuronat de sodiu prezintă nu numai proprietăţi vâscoelastice dar evidenţiază şi uşor comportament reopectic (de exemplu, vâscozitate crește cu timpul, la viteza de forfecare constantă). Atât sulfatul de condroitină cât şi hialuronatul sunt molecule elicoidale cu lanțuri drepte, în medii extrem de vâscoase la temperaturi reduse, ambele molecule au o mobilitate mai scăzută în alinierea grupărilor N-acetilamină pentru interacțiunea reciprocă, interacțiune care are loc într-un ritm foarte lent. Creşterea temperaturii conduce la intensificarea interacțiunii reciproce ca urmare a creșterii ratei cinetice și o mai bună mobilitate a moleculelor în a-şi alinia grupurile N-acetilamină pentru legături de hidrogen. Când amestecul este supus la o viteză mare de forfecare, moleculele sunt aliniate sau orientate pentru interacțiune-lipire, astfel că vâscozitatea creşte când amestecul este supus la viteză mare de forfecare, și/ sau creșterea temperaturii, rezultând un compus modificat, cu o greutate moleculară mare.

The neonatal mortality rate in Nepal was 21 per 1,000 live births in 2016; about four-fifths (79%) of all neonatal deaths were early neonatal deaths and 57% of all births were institutional births . There are large variations in neonatal mortality within provinces of Nepal from 15 to 41 per 1,000 live births. Nepal needs to reduce its neonatal mortality rate by half in the next 10 years to achieve SDG3.2. Accelerated efforts are thus needed to address interprovincial disparities. Neonatal near miss (NNM) is a novel concept that has recently emerged and is similar to maternal near miss (MNM). It provides vital information required for evaluation of the quality of care in hospitals and explores opportunities to improve the performance of healthcare providers . Near-miss events occur three to eight times more often than neonatal deaths [6, 7]. Thus, NNM evaluations can provide abundant evidence of the causal pathways responsible for neonatal deaths .

To determine the importance of the phenotype-based cage choice, we ran two control simulations with different immigration probabilities. In the first, the capture cage was chosen at random (i.e. no phenotype-dependent habitat choice) while in the other, white-eyed flies always chose cage 0 and wild type flies always chose cage 4 (i.e. habitat choice was completely phenotype-dependent). The remaining parameters were unchanged, and departure was always independent of eye-color phenotype. We performed 1000 iterations of each of the three simulation setups and compared the resulting proportions of same-phenotype pairs.

La survenue d'une fracture au niveau de l'un ou des deux os de l'avant-bras met en jeu la précision du positionnement de la main dans l'espace, en raison de la perturbation des mouvements de pronosupination. C'est la raison pour laquelle la conviction des chirurgiens orthopédistes est allée vers le traitement sanglant de toute fracture des deux os de l'avant-bras. Cette attitude explique la rareté de cals vicieuse des deux os de l'avant-bras dans les pays industrialisés, situation devenue l'apanage des fractures traitées orthopédiquement. Par contre elle pose encore un problème thérapeutique et fonctionnel dans les pays en voie de développement. L'objectif de notre étude est de présenter notre expérience dans la prise en charge des cal vicieux de l'avant-bras.

Rycina 1. przedstawia schemat diagnostyki zakażenia wirusem cytomegalii u ciężarnej oraz jej płodu opracowany na podstawie schematów Lazzarotto i Munro [21, 37]. Z uwagi na zwięzłą formę schematu, która wymusza uogólnienia i nie uwzględnia wszystkich możliwych wariantów, należy dodać, że izolowana obecność IgG (IgG dodatnie i IgM ujemne), nie wyklucza zakażenia wrodzonego, ze względu na możliwą reinfekcję innym serotypem wirusa, lub reaktywację wirusa uśpionego. Ponadto ujemny wynik badania metodą PCR z płynu owodniowego nie wyklucza zakażenia płodu, do którego może dojść po wykonaniu amniopunkcji.

In the analysis stage, domain experts and programmers have to identify all the situations that can be relevant for the system to be developed, specifying a name, a description and the desired behaviour of the system once the situation is detected. Also, each of the identified situations have to be parameterized with the entities that are involved in the situation, the location where the situation can be identified and the interval of time when the situation can be detected. The needed inputs of context data in order to detect the situation have to be specified as well, providing the objective, the conditions and the restrictions for each data type. Finally, the needed outputs once a situation is detected have to be specified. These outputs will be used by programmers in order to adapt the system's behaviour according to the previous specifications. In order to support the analysis stage, a spreadsheet has been designed, where domain experts and programmers can discuss about the needed parameters of each of the identified situations.

According to the results, women with first FSH ≥10 had more ovarian response and pregnancy than stable FSH ≥10 and women with persistently normal FSH had the highest response and pregnancy. This is in accordance with previous researches (11). In women whose FSH levels were constantly elevated, MIS concentration was significantly higher in ART cycles resulting in pregnancy. Also this was true for the group with stable FSH ≥10, but did not reach to a statistically significant result.

W etiologii wielohormonalnej niedoczynności przysadki rozpatruje się wpływ czynników środowiskowych i genetycznych. W przypadku wrodzonego charakteru schorzenia, ujawnienie objawów choroby może nastąpić w okresie niemowlęcym, a nawet wczesnodziecięcym. Częstość występowania ocenia się na około 1 na 50 000 urodzeń, z czego w 10 do 35% obserwuje się współwystępowanie cholestazy . Wrodzona niedoczynność przysadki dotyczy najczęściej kilku osi hormonalnych, jednakże możliwe są sporadyczne przypadki izolowanej niedoczynności przysadki w zakresie np. wydzielania ACTH, mówimy wtedy o izolowanym niedoborze ACTH .

Premièrement, la formulation des modalités de réponse aux questions a été revue par rapport au HSOPSC, en remplaçant la modalité intermédiaire « neutre » par « ni pour ni contre ». En revanche, la formulation des modalités de réponse aux questions fréquentielles est restée fidèle au questionnaire hospitalier. Concernant la formulation des 42 questions sur les différentes dimensions de la culture de sécurité, la proposition initiale du binôme de traduction a été retenue d’emblée pour 14 d’entre elles. Les discussions engagées par le groupe de traduction sur les autres questions portaient sur le choix des termes, sur le choix des exemples, sur des questions d’interprétation ou sur la possibilité de simplifier/clarifier les questions.

手术和化疗是肺腺鳞癌患者的主要治疗方式，在我们的研究中手术和化疗也是患者预后独立的影响因素，接受手术和化疗的患者预后会更好，不管是单因素分析还是多因素分析，手术的患者预后更佳，这和患者的分期相关，一般来说，能手术的患者分期偏早。而化疗在单因素分析中提示接受化疗的患者预后较未接受化疗的患者差，多因素分析排除其他因素后提示化疗对于非腺鳞癌仍旧是较好的预后因素。靶向治疗是肺腺鳞癌未来的发展方向，但目前对肺腺鳞癌患者的靶向治疗方案及效果鲜有报道。肺腺鳞癌的基因突变也具有不同于肺腺癌和肺鳞癌的特征。Powrozek等和Shiozawa等分别报道28.6%和23.7%的肺腺鳞癌患者中存在EGFR突变。Vassella等报道30%和25%的肺腺鳞癌患者分别存在EGFR和PI3K信号通路的突变。Liu等报道48.1%的肺腺鳞癌患者肿瘤组织中PD-L1表达阳性。

To purify the C. violaceum chitinase produced in E. coli, the secreted recombinant protein was recovered from the cell-free culture supernatant by ammonium sulfate precipitation and further purified by single-step affinity chromatography on a chitin matrix. After washing out the unbound proteins (Peak 1 - P1) with equilibration buffer (Figure 4A), pure recombinant chitinase was eluted (Peak 2 - P2) by washing the column with 0.1 M acetic acid, as shown by SDS-PAGE (Figure 4B). A small amount of chitinolytic activity was detected in the pooled fractions of P1, but this value was approximately 1% of the total activity in the pooled fractions of P2, showing that the binding of rCvChi45 to the chitin matrix was effective. A purification factor of 14.9-fold was obtained, and ca. 60% of the total chitinolytic activity which was present in the cell-free culture supernatant was recovered. The yield of purified recombinant protein was ca. 4 mg per liter of induced culture, which represents approximately 7% of the total protein content in the concentrated cell-free culture medium. When submitted to electrophoresis under denaturing conditions (SDS-PAGE), the purified protein migrated as a single band with an apparent molecular mass of approximately 43.8 kDa, instead of 45.7 kDa, the expected size of the 439-residue precursor encoded by the DNA sequence cloned into the expression vector. However, taking into account the extra residues at the C-terminus (LEHHHHHH; molecular mass = 1,082.49 Da) corresponding to the His-tag sequence added to the recombinant protein, this value (43.8 kDa) is in good agreement with the predicted molecular mass (ca. 44.2 kDa) calculated for the expressed His-tagged fusion protein without its native signal peptide. The N-terminal sequence of the purified recombinant chitinase secreted into the culture medium was determined to be: ACPGEWAEGTAYKVGDVVSYNNANYTALVAHTAYVGANWN. This sequence corresponds to a 40-residue segment of the pre-protein, from Ala25 to Asn63, excluding the first 24 residues, as highlighted in Figure 1. The presence of a signal peptide at the N-terminal region of the protein sequence encoded by ORF CV2935 was predicted by the SignalP software (probability = 1.0, calculated using the hidden Markov model of SignalP). Furthermore, three most likely cleavage sites for type I signal peptidase (SPase I) were predicted within the first 70 residues in the precursor sequence of CvChi45. These sites were located between Ala21-Trp22 (cleavage site score = 0.288; neural network model of the SignalP algorithm), Ala23-Ala24 (C-score = 0.546) and Ala24-Ala25 (C-score = 0.360). As shown by the experimentally determined amino terminal sequence, the native signal peptide was cleaved between Ala24-Ala25, which was the second most likely SPase I cleavage site as predicted by the neural network model of the SignalP algorithm. Thus, the native signal peptide in the precursor sequence of CvChi45 was recognized by the general secretory apparatus of the E. coli and directed the secretion of the expressed protein into the culture medium. Moreover, the signal peptide of CvChi45 was correctly processed to produce a mature extracellular enzyme with chitinolytic and chitin-binding activities.

Two major ‘macronutrients’ typically limit and control biological production in marine ecosystems, nitrate (N) and phosphate (P). Both are essential components of living organisms, such as amino acids and proteins (N) or nucleic acids (P), and their relative molar ratio (N:P) is typically used to assess the limiting element for primary production in ocean regions (Smith, 1984).

The final noise reduction step is a matched filter which corresponds to a bandwidth limitation and demodulation based on knowledge of the excitation signal g(n). The length of the matched filter Tmf (N samples) is an assumption on how long the desired signal d(n) is approximately constant. In the stationary case, one might choose a very long (e.g., multiple seconds) and therefore narrow matched filter to achieve a superior noise performance. In the 1D motion case (>0.1 m/s), the assumption of a constant d(n) for such a filter is invalid. Consequently, the matched filter distorts the estimation result d^(k) by suppressing high frequency components of d(n).

Kidney tissue samples from 18 subjects with DKD and 9 reference subjects without DKD were acquired and studied (Table 1). The mean age at tissue acquisition was 55.0 years of age in subjects with DKD and 50.0 in the reference nephrectomy subjects. Subjects with DKD were 61.1% female and 27.8% were Black. Most DKD subjects had nodular glomerulosclerosis and about half had greater than 80% effacement of podocyte foot processes. Nephrotic range proteinuria was observed in 55.6% of DKD subjects. Baseline eGFR was 63.2 ± 26.2 mL/min. Subjects lost an average of 14.5 mL/min/year of eGFR over follow-up duration, which was 47.7 months on average. As a molecular comparator group, nine reference nephrectomy samples were obtained. These samples were evaluated by a blinded renal pathologist (C.P.) and did not show histologic evidence specific for diabetic kidney disease; however, clinical and demographic data such as race, proteinuria, and eGFR were not available.

We conducted two studies to test our hypotheses. Study 1 was conducted with Master of Business Administration (MBA) students in China. Although nearly all hypotheses were supported in the MBA student sample, we anticipated that the research results could be generalized to business organizations. In addition, we expected that the self-developed measure for taking responsibility could be verified again in a new sample. Therefore, we conducted Study 2 to attempt to replicate the results of Study 1 in a business and to provide stronger evidence for the self-developed measure. Study 2 was conducted in a trading company located in a southern province of China, which provided stronger evidence for generalizability and for our new scale of taking responsibility. Together, the two studies evaluated our research model through field methodologies, which strengthened the ecological validity of our conclusions.

La complication majeure des fractures de l'extrémité proximale du tibia est l'arthrose, exigeant ainsi une réduction anatomique de la surface articulaire, la restauration de l'alignement axial et une fixation stable, permettant une mobilisation active et passive immédiate pour obtenir des résultats satisfaisants . Quel qu'il soit le traitement, le but ultime est de préserver les amplitudes articulaires du genou [2, 10, 11]. En général, le traitement chirurgical est indiqué pour les fractures articulaires avec un enfoncement et/ou séparation de 3 à 5 mm et instabilité en varus/valgus plus de 10° [12, 13]. Le traitement chirurgical habituel, qui comprend une réduction à foyer ouvert avec fixation interne, a démontré des résultats satisfaisants mais avec une dissection extensive [14, 15]. En plus cette technique dans plusieurs situations nécessite une arthrotomie sous méniscale avec relèvement méniscal pour un meilleur controle de la réduction articulaire, ce qui est souvent source de raideur importante, douleur prolongée et problèmes de cicatrisation [5, 13, 15]. La fixation percutanée arthroscopiquement assistée, recommandée pour la première fois par Caspari et Jennings , est devenu populaire depuis son utilisation comme moyen diagnostique. Cette technique permet une visualisation directe du trait articulaire, une meilleure réduction, moins de morbidité par rapport la technique à ciel ouvert et un traitement immédiat des lésions intra-articulaires associées, la prévention des complications des parties molles et la possibilité de lavage articulaire comprenant les débits chondraux et l'hématome [17–20]. Fowble et al rapporte que les résultats du traitement sous arthroscopie sont meilleurs par rapport à la technique à ciel ouvert, et met en évidence une bonne réduction anatomique, un taux de complications moindre et un délai plus court pour la reprise de l'appui. Ohdera et al ne rapportent pas de différence concernant la durée de l'acte chirurgical, les amplitudes articulaires du genou et les résultats cliniques entre les patients traite opérés a ciel ouvert et ceux opérés sous arthroscopie; cependant ils notent une rééducation plus rapide et plus facile parmi les patients traites sous arthroscopie. Il est rapporté que ce n'est pas toutes les fractures des plateaux tibiaux sont accessibles au traitement sous arthroscopie, ainsi les fractures classées Schatzker IV et V, dues à des traumatismes à haute energie, associées souvent à des risques de syndrome de loges ne présentent pas une bonne indication [2, 12, 19]. Par ailleurs les type I, II et III représentent les meilleures indications pour cette technique selon Tornetta et Kayali [9, 19].

Ортологичные гены устойчивости к M. chitwoodi – RMc1( fen) и RMc1(hou) – идентифицированы у аллополипло- идных мексиканских видов Solanum hougasii и S. fendleri (Brown et al., 1999, 2003, 2009; Draaistra, 2006) (см. табл. 2). В серии работ C.R. Brown с коллегами (1996, 1999, 2003, 2009, 2014; Zhang et al., 2007) получены интрогрессивные формы картофеля поколений ВС5–ВС6 с генами RMc1(blb), RMc1( fen) и RMc1(hou) диких мексиканских видов, а также разработаны сцепленные с ними STS- и CAPS-маркеры для проведения маркер-опосредованной селекции. Устой- чивость интрогрессивных форм обусловлена генерацией активных форм кислорода и активацией защитных меха- низмов, в которых центральную роль играет салициловая кислота. Она запускает реакции сверхчувствительности и каскада физиологических и биохимических реакций, предотвращающих развитие M. chitwoodi в корнях рас- тений (Bali et al., 2019). Важно отметить, что клоны с идентифицированным геном RMc1( fen) устойчивости к M. chitwoodi одновременно обладали и устойчивостью к M. fallax (Draaistra, 2006).

The relationship of adapiforms to living primate groups has always been a matter of debate. Recently, this debate has been re-kindled by the discovery of an exceptionally complete skeleton of the European cercamoniine Darwinius masillae . Disagreement about the phylogenetic significance of its morphology highlights the need for more complete documentation of early euprimate anatomy as well as a more quantitatively rigorous and broadly acceptable (by researchers with different philosophies on phylogeny reconstruction) analytical framework .

Figure 5a shows the admittance curves of the bare FBAR device, illustrating the shear and longitudinal resonances to be near 1.87 GHz and 3.15 GHz, respectively. Generally, the resonant frequency (fR) of bulk acoustic devices can be estimated by fR = v/2d, where v and d are the acoustic velocity and thickness of the piezoelectric layer. From the resonant peaks in the conductance curves, the corresponding shear velocity v(S) and longitudinal velocity v(L) were 5610 m/s and 9450 m/s, respectively. As a comparison, the theoretical acoustic velocities of the AlN film with the c-axis inclination angle of 22° were calculated to be v(S) = 6221 m/s and v(L) = 10,268 m/s from the basic piezoelectric constitutive equations as follows : (2)v(S)=[c33E′¯+c55E′¯2ρ−(c33E′¯−c55E′¯2ρ)2+(c35E′¯ρ)2]1/2 (3)v(L)=[c33E′¯+c55E′¯2ρ+(c33E′¯−c55E′¯2ρ)2+(c35E′¯ρ)2]1/2 where cE′33 and cE′55 are the piezoelectrically stiffened elastic constants in the material coordinate system with inclined c-axis and ρ is the density of AlN film.

All patients were native Polish speakers with an intermediate or higher educational level. They were operated and followed up at the Department of Reconstructive Surgery and Arthroscopy of the Knee Joint, Medical University in Łódź between January 2007 and August 2009. The subjects had undergone reconstructive ACL surgery and, in case of combined injury both ACL reconstruction and meniscal resection. The reconstruction was made endoscopically with bone–patellar tendon–bone grafts that were stabilized with titanium interference screws. All patients had undergone standardized moderately accelerated, six months’ rehabilitation program . The mean follow-up time was 1.3 years (0.4–3.4). At time of follow-up all subjects had returned to their normal activities.

Although ROS accumulation mediated the anti‐cancer effect in gastric cancer cells in vitro and in vivo, the involved mechanism is not clear. Therefore, we next explored the mechanism for JS‐K‐induced ROS accumulation. Reduction of MRC complex activity promotes electron escape to produce ROS; therefore, we determined the effects of JS‐K on MRC complex activity. Figure 6A shows that JS‐K decreased the activities of MRC complex I and IV in a time‐dependent manner but had no inhibitory effect against MRC complex II, III and V in SGC7901 cells, indicating that the reduction of the MRC complex I and IV activities contributed to JS‐K‐induced ROS accumulation. As NAC partially reversed the negative effect of JS‐K on MRC complex I and IV activity (Figure 6B), it is possible that the accumulated ROS suppressed MRC complex I and IV activation in a feedback loop. In addition, we also detected the activities of MRC complex I and IV in gastric cancer xenografts and found that the activities of MRC complex I and IV were significantly lower in the JS‐K‐administered group than those in the negative control group (Figure 6C), further confirming that the reduction of MRC complex I and IV activity contribute to ROS accumulation induced by JS‐K. To explore the potential mechanism of JS‐K‐induced reduction of MRC complex I and IV activity, we determined the effect of JS‐K on the protein levels of Ndufs4 and COX2, the core enzymes in MRC complex I and IV, respectively. As shown in Figure 6D, JS‐K time‐dependently down‐regulated Ndufs4 and COX2 in SGC7901 cells. Moreover, JS‐K administration suppressed Ndufs4 and COX2 expression in gastric tumour tissues (Figure 6E). Therefore, JS‐K‐induced down‐regulation of MRC I and IV core proteins results in the reduction of MRC complex I and IV activity, and then promotes ROS production. In addition, ROS are usually cleared by antioxidant enzymes, including SOD1 and catalase; thus, the suppression of antioxidant enzyme activation also facilitated ROS accumulation. Therefore, we next explored the effect of JS‐K on SOD1 and catalase activity. As shown in Figure 6F, JS‐K induced a decrease in SOD1 and catalase enzyme activity in SGC7901 cells in a dose‐dependent manner. Moreover, JS‐K administration (1.5 and 3 mg/kg) significantly decreased SOD1 and catalase activity in gastric tumour tissues (Figure 6G); therefore, JS‐K could decrease SOD1 and catalase activity in vivo and in vitro, which would also contribute to JS‐K‐induced ROS accumulation. As SOD1 and catalase activity depends on their protein levels, we also determined whether JS‐K down‐regulated SOD1 and catalase expression. As shown in Figure 6H, JS‐K dose‐dependently decreased SOD1 and catalase protein levels in SGC7901 cells. Moreover, JS‐K administration also significantly suppressed the expression of SOD1 and catalase in gastric tumour tissues (Figure 6I), indicating that JS‐K down‐regulates SOD1 and catalase in vivo. Therefore, the down‐regulation of SOD1 and catalase induced by JS‐K may contribute to the reduction of SOD1 and catalase activity.

Figure 2A shows that insulin stimulation failed to increase AKT phosphorylation in lung tissue and isolated bronchi of obese mice as compared with lean group (p < 0.05; n = 6). Resveratrol treatment significantly enhanced AKT phosphorylation in both lung tissues (Fig. 2A) and isolated bronchi (Fig. 2B) of obese mice to similar levels of lean mice (n = 6). In lean group, resveratrol treatment did not affect significantly the AKT phosphorylation in lung tissue and isolated bronchi (Fig. 2A,B).Figure 2Expressions of phosphorylated AKT (panels A and B), IRS-1 (C) and IRβ (D) in lean and high-fat diet-fed mice, treated or not with resveratrol (Resv; 100 mg/kg/day, 2 weeks).

We acknowledge that the function of AAAL domain has been insufficiently discussed in the main text and thank the reviewers for pointing it out. We now discuss this topic on several occasions in the manuscript. In summary, we cite the previous work showing AAAL interacts with chromatin, but point out our previous measurements showing that this interaction has a much lower affinity than BAH-nucleosome interaction (Introduction). In light of the data presented in this manuscript, we argue that AAAL domain has a clear (synergistic or additive) role in stabilizing the binding of Sir3 to nucleosome, but does not directly affect binding cooperativity to di-nucleosomes (Results).

In Section 4, we derive novel upper and lower bounds on the capacity of a MIMO channel that is subject to an arbitrary constraint on the support of the input. In particular, three families of upper bounds are proposed, which are based on: (i) the maximum entropy principle (see the bound in Theorem 9); (ii) the dual capacity characterization (see the bound in Theorem 10); and (iii) a relationship between mutual information and the minimum mean square error that is known as the I-MMSE relationship (see the bound in Theorem 11). On the other hand, Section 4 provides three different lower bounds. The first one is given in Theorem 12 and is based on the entropy power inequality. The second one (see Theorem 13) is based on a generalization of the celebrated Ozarow–Wyner bound to the MIMO case. The third upper bound (see Theorem 14) is based on Jensen’s inequality and depends on the characteristic function of the channel input distribution.

Since two of the autogamy time course experiments were carried out in parallel and provide true biological replicates (A1 samples in Additional file 1, Table S1; see also Additional file 2, Figure S1), we used those microarrays to identify a large set of differentially expressed genes independently of any biological classification of the samples. The 12 microarrays of the A1 series, 2 per time point, were normalized together, and for each gene, the minimum and maximum log2 signal intensities across the 12 microarrays were used to extract the 2000 genes with the largest expression difference during autogamy. Then the complete set of autogamy time course experiments, including the A1 biological replicates and the A2 and A3 time series, were normalized together, and the signals from the 2000 selected genes were used for agglomerative hierarchical clustering of the microarrays, using the Spearman correlation coefficient as a proxy for distance. The dendrogram obtained (data not shown, but equivalent to the sample clustering in Figure 1) gave the same sample classification as the nuclear morphology, except for the time points DEV2 and DEV3, which could not be resolved. This could reflect progressive loss of synchrony across the time course or little if any change in gene expression between DEV2 and DEV3, non-exclusive hypotheses. We note that molecular data, not available for all of the microarray samples, can differentiate the DEV2 and DEV3 time points: the relative abundance of double stranded breaks and covalently closed circular intermediates of the IES excision pathway is different .

Human adult mesenchymal stem cells (hMSCs) are a class of multi-potent cells that can readily differentiate into adipocytes, chondrocytes, and osteoblasts . These cells have been of particular interest over the past decade due to their tissue regenerative potential. However, investigations have recently turned toward understanding the role hMSCs play in the development and progression of cancer. Tumor microenvironments often produce a number of chemokines (e.g., CCL25, TGF-β) that can attract circulating hMSCs [2–3]. Once inside the tumor, hMSCs attempt to “repair” these microenvironments, since they appear damaged in comparison to the surrounding normal tissue [4–5]. Concurrent with these activities, numerous cross-talk interactions are thought to occur between tumor and stem cells, which can lead to cancer progression. Current literature has implicated hMSCs in the promotion of osteosarcoma and colorectal cancer, metastasis of breast cancers, as well as chemotherapeutic resistance [6–11].

It is fundamental to accurately identify populations with the most need of healthcare interventions to effectively evaluate the performance of healthcare systems.22 This provides evidence to support decision making concerning (1) planning for safer births and healthier new-borns and (2) resource allocation and improving access to maternal and perinatal healthcare as this is one of the main focuses in healthcare delivery.2 23 Inaccurate identification of the populations in need of maternal healthcare interventions has been one of the causes of the variations in the utilisation of maternal healthcare.24 The use of poor information in research and policy making leads to inefficient allocation of limited resources deterring the desired achievement of improved maternal and perinatal health quality. A true representation of the maternal and perinatal population distribution is therefore crucial in the successful implementation of interventions and it can only be achieved using accurate and highly disaggregated geographical data. Emphasis is on accuracy and detail of the population distribution datasets as their applications have become more intensive and their implications more pronounced in the achievement of the new SDGs.25

In philosophy, we use a technical sense of ‘intuition’ such that describing a claim as ‘intuitive’ actually strengthens it. Intuitive claims aren’t just lacking a certain kind of support; intuitions offer their own kind of respectable, reliable evidence. So, the dominant role of intuition-talk cannot be a form of hedging.

Lentivirus was stored at -80°C in aliquots prior to infection and was limited to one freeze-thaw cycle before use. Target cells were grown to 33–66% confluency in 6-well or 12-well plates before infection. For every infection condition, equally titered copy numbers of each virus were used in the presence of 6 μg/mL polybrene. Each plate was spun at 2,000 rpm for one hour at room temperature. The spinfection procedure was repeated 24 hours later and fresh media was added at 48 hours. Cells were grown for a total of 3–6 days after the initial infection before collection and the media was changed every other day.

Retrospectivamente, este estudo incluiu pacientes com sintomas sugestivos de DAC significativa encaminhados para TCC. Após os achados desse exame, foram encaminhados por decisão clínica para o cateterismo cardíaco (com intervalo menor de 30 dias) e que realizaram análise de FFRi no Hospital Sírio-Libanês (São Paulo-SP), entre janeiro de 2014 e fevereiro de 2018. No total, houve 17 exclusões: 14 por fatores limitantes para o cálculo da FFR TC descriminados pelo fabricante da ferramenta (8 por lesão de tronco de coronária esquerda [TCE], óstios ou bifurcações; 6 pela presença de stent ); e 3 por imagem com qualidade insuficiente devido a calcificação excessiva e significativos artefatos de movimento. Durante o pós-processamento das imagens, não houve exclusão de pacientes por impossibilidade técnica de o software realizar a quantificação da FFR TC. Ressalta-se que as recomendações do fabricante com relação a lesões de TCE, óstios ou bifurcações têm sido seguidas também por outros autores, 11 e parecem estar relacionadas ao reconhecimento limitado das bordas anatômicas nesses cenários. Esse estudo foi aprovado pelo Comitê de Ética em Pesquisa do Hospital Sírio-Libanês.

The study suggests there is no evidence to support the claim that circumcision prevents premarital sex and ensures marital fidelity in Nigeria. While we strongly discourage FGM in all its forms, we assert the need for alternative and acceptable health promoting community measures to address these inherent sexual perceptions toward reducing FGM and improving sexual and reproductive health across population groups.

CTCs是从原发性或转移性肿瘤组织流入外周血液的罕见癌细胞。这些CTCs的表型和遗传特征可以为指导癌症分期和治疗提供重要信息，因此进一步研究它们的特征和性质是一个相当有价值的领域，也为液体活检提供细胞来源[9, 10]。在外周血中，约每106个-107个白细胞中可能仅有1个CTCs，因此CTCs富集分离是首要问题。CTCs检测基本过程是先对其进行分离富集，再进行分析。富集和分析的方法基于CTCs的物理和生物学特性，例如大小、变形性、密度、极性和电荷、上皮细胞黏附分子、细胞角蛋白和表达的肿瘤相关标志物。CTCs富集的方法主要有：密度依赖性细胞分离、基于细胞大小的分离、免疫磁珠阴性富集、基于磁泳移动性的分离、免疫磁珠阳性富集和通过微流体装置富集。对CTCs进行分析的方法有：逆转录PCR技术、荧光原位杂交技术和荧光辅助细胞分选技术。另外可同时富集和分析CTCs的方法有：光纤阵列扫描技术、CellSearch、基于形态学富集的膜过滤技术（isolating by size of epithelial tumor cells, ISET）、AdnaTest和EPISPOT等。目前还有一些新兴技术如利用声波定向微流体将肿瘤细胞与白细胞分离，有助于我们快速准确地从全血中分离和分析CTCs。

Several different forms of glycosylation exist. The N- and mucin-type O-glycosylation are the most common. The mucin-type O-glycosylation is found in high density on glycoproteins attached or associated with the cell membrane and is known to modulate protein structure, intracellular sorting of proteins, cell-cell adhesion, and cell maturation . The mucin-type O-glycosylation is defined as the covalent attachment of an N-Acetylgalactosamine (GalNAc) residue to a polypeptide backbone at the hydroxyl group of serine and threonine. The most immature O-glycans are designated Tn (GalNAcα1-O-Ser/Thr), sialyl-Tn (NeuAcα2-6GalNAcα1-O-Ser/Thr), and T (Galβ1-3GalNAcα1-O-Ser/Thr). The majority of these are subsequently elongated and modified to more complex structures with different functions. The initial attachment of GalNAc is catalysed by a large family (20 members) of homologous polypeptide GalNAc-transferases (GalNAc-Ts) and takes place in the Golgi apparatus . The different GalNAc-T isoforms are differentially expressed in different tissues and cells and have different specificities for acceptor peptide sequences . GalNAc-T1 and -T2 are the most widely distributed GalNAc-Ts, being expressed in most human tissues, whereas GalNAc-T3 has a more restricted expression, e.g., in the testes, kidney, and reproductive and gastrointestinal tracts . We have previously shown that these simple O-glycans and the GalNAc-Ts are developmentally regulated in the human testis, and that GalNAc-T3 likely is the only GalNAc-T present in spermatozoa . These findings led to the hypothesis that this restricted glycosylation pattern in germ cells may be crucial for the function of spermatozoa.

To assess the impact of individual studies on pooled estimates, sensitivity analysis was performed by omitting one study at a time. Figure 3 presents the pooled estimates after each study was omitted. Overall, no single study was identified to be substantially influential on the pooled estimates. For the current HRT users, omitting the most influential study by Ji et al. resulted in pooled HRs of 0.67 (0.57–0.80) for colorectal cancer mortality and 0.76 (0.67–0.87) for all-cause mortality, which were close to the primary analysis of 0.71 (0.62–0.80) for colorectal cancer mortality and 0.74 (0.67–0.81) for all-cause mortality. In a second sensitivity analysis, we re-ran the analysis with a fixed-effect meta-analysis. The effect estimates on colorectal cancer and all-cause mortality for current and former HRT users were unchanged (Additional file 1: Figure S5 and S6). Fig. 3Sensitivity analysis. The association between current HRT use in women with colorectal cancer and (a) colorectal cancers and (b) all-cause mortality. Note.

Nous avons mené une étude rétrospective des cas de mélanomes ano-rectaux primitifs pris en charge au service de gastro-entérologie et d'oncologie sur une période de 15 ans du janvier 1997 - Décembre 2012. Pour réaliser cette étude on s'est basé sur l’étude des dossiers médicaux des patients et l'analyses des registres des examens proctologiques réalisés durant cette période. Quatorze cas ont été observés. La confirmation du diagnostic a été faite chez tous les malades par une étude histologique des biopsies réalisées lors de la rectoscopie, et après un examen cutané minutieux et ophtalmologique pour éliminer une autre origine du mélanome. Un bilan d'extension a été réalisé par la suit permettant de classer ces malades en trois stades selon la classification de Slingluff obligatoire pour la suite de la prise en charge notamment thérapeutique.

Our primary goal in this study was to determine whether imaging of single-cell lysates with EM could yield sufficient, high-quality particles for 3D structure determination. To obtain intact, native particles from single cells, C. elegans zygotes (i.e. 1-cell embryos) were trapped and lysed using microfluidic chambers (Fig. 1) (see “Experimental Procedures”). We then transferred the cell lysates (a volume of ∼50 nl) from the microfluidic channels to EM grids using a glass needle (Video S1) (see “Experimental Procedures”). Because of the small volume, which was insufficient to coat an entire grid, we used reference grids containing alphanumeric markers to locate the placement of our samples under both the dissecting scope and the electron microscope. Each reference grid was then conventionally stained using 2% (w/v) uranyl acetate. We chose to use negative stain EM for its high signal-to-noise ratio to more accurately assess our ability to identify single particles from individual cell lysates. Each grid was then examined by transmission EM to identify grid squares that contained cellular protein particles embedded in stain.

OLP is a debilitating mucosal disease which can be unresponsive to topical CS and might run a chronic course . In this study, we report the outcomes of a series of 21 consecutive patients with steroid-refractory OLP, who underwent a predefined treatment regimen with low-dose CSA mouth rinse (2 mL twice daily) for four weeks followed by discontinuation of treatment for another four weeks. Pain (VAS), clinical picture (PGA) and quality of life (DLQI) were assessed at the beginning of treatment, at four weeks—when CSA therapy was discontinued—and after another four weeks without therapy. Overall, we found that four weeks of continuous topical CSA resulted in a significant reduction in pain (p = 0.0003), and vice versa, discontinuation of CSA led to a significant and relatively swift recurrence of pain at week eight (p = 0.032) (Figure 2, Figure 3 and Figure S1).

Each trial consisted of a series of 3,000 random, uncorrelated displacements generated by the robotic arm. Each displacement was a center-out-and-back movement in a random direction to the surface of spheres with 2, 5, 10, and 20 mm in radius. Trials were block-randomized across sphere sizes. We recorded a total of eight trials (4 sphere sizes × 2 necks stiffnesses) (Table 1).

The mechanism of development of BIA-ALCL is unclear. It has been postulated that chronic inflammation due to a bacterial biofilm, more prevalent on textured implants, leads to T-cell hyperplasia and subsequent malignant transformation . Somatic mutations leading to increased activation JAK/STAT signalling, particularly STAT3 gene mutations, are common, suggesting that this is the main driver pathway in BIA-ALCL .

In this report, we explore the hypothesis that phosphorylation of eIF4G1 can be a differential control mechanism between brain regions that are resistant and vulnerable to ischemia. For this purpose, we studied whether the phosphorylation of eIF4G1 could operate in the eIF4E/eIF4G association complex as a regulatory mechanism in the translation inhibition induced by ischemia-reperfusion, analyzing their phosphorylation status in SHC3d control and R3d ischemic samples of the cortical resistant and CA1 vulnerable regions. This study has been conducted in ischemic young adult animals, although aging and co-morbidities are important determinants of outcome after an ischemic stroke. Since this study investigates a molecular mechanism in brain regions vulnerable to ischemia, the inclusion of a co-morbidity in the study would mean that the molecular mechanism could be associated with processes related to co-morbidity, rather than with a precise knowledge of the ischemic pathophysiology. In addition, the results obtained may be specific to the co-morbidity studied and exhibit new effects in a different co-morbidity. Therefore, co-morbidity has been avoided in this study. From the results achieved in this report, several novel findings can be concluded: (i) phosphorylation of eIF4G1 at Ser1147, Ser1185, and Ser1231 is present in brain tissue, without changes between the different regions studied nor between the control or the ischemic condition; (ii) among the three phospho-sites studied, the phosphorylation of eIF4G1 at Ser1147 was the only one found in the eIF4E/eIF4G association complex from the cap-containing matrix (m7GTP-Sepharose); (iii) phosphorylation of eIF4G1 at Ser1147 is increased in the vulnerable CA1 region in response to IR stress, as demonstrated eIF4G1 immunoprecipitation assays; and (iv) phosphorylation of eIF4G1 at Ser1147 is colocalized with eIF4E in brain sections, with higher levels in the CA1 region after IR.

The ability of NB-MSC to modulate T lymphocytes proliferation was evaluated as previously described . Phytohemagglutinin (4 μg/ml, PHA-P; Sigma-Aldrich) activated PBMCs were cultured in the presence or absence of MSCs at different NB-MSC: PBMC ratios (1:2, 1:20, and 1:200). After 48 h incubation at 37 °C, 5% CO2, cultures were pulsed with 3H-thymidine (1 μCi/well, specific activity 6.7 μCi/mmole, Perkin Elmer, Waltham, MA) and harvested after 18 h. 3H-thymidine incorporation was measured by gamma-counter (PerkinElmer Massachusetts, USA). Experiments were performed in triplicate and results were expressed as Stimulation index (SI = cpm stimulated/cpm unstimulated).

In the current study, wheat straw and ensiled lucerne were steam pretreated and hydrolysed using enzymes. After the enzymatic hydrolysis (EH), the materials were filtered to obtain the wheat straw hydrolysate (WSH) and the lucerne hydrolysate (LH) (Fig. 1a). Wheat straw was steam pretreated with acetic acid as catalyst and lucerne both with and without acetic acid as a catalyst, followed by enzymatic hydrolysis (EH). Lucerne cultivated in pure culture was used, because of the unavailability of lucerne intercropped with wheat and the advantages of optimising conditions for pure substrates rather than mixtures (Fig. 1).Fig. 1Flow chart illustrating a hydrolysis of plant material and b use of hydrolysates in dark fermentation and anaerobic digestion.

Kasumi-3 cells were infected with HCMV strain TB40/Ewt-GFP (48) (MOI of 1 to 2) using centrifugal enhancement of infection, as described in Text S1 in the supplemental material (84). GFP+ and GFP− cells were sorted on a FACSAria-6 laser cell sorter (BD Biosciences). Infected cells were cultured for 13 days to establish latency, with medium changes every 2 to 3 days. For reactivation studies, cells were treated with 5 ng/ml TNF-α at 14 dpi for 3 days at 37°C. A 50% tissue culture infective dose (TCID50) assay was used to determine the infectious titer of infected cell supernatants.

Achieving the right pancreatic organoid structure in vitro during differentiation process may aid in obtaining the right beta cell heterogeneity. In vivo maturation of pancreatic progenitors may allow this within the encapsulation device. However, terminally differentiated beta cells generated in vitro using optimized protocols may not have had the access to the in vivo micro-environmental factors necessary for appropriate islet organoid development, and as a result may have generated pancreatic beta cell sub-populations disproportionately.

Demographic data and laboratory parameters were collected at baseline. The baseline was defined as the time when patients received the first clinical evaluation within 3 months after the initiation of PD. The following demographic and comorbidity characteristics were collected: age, gender, underlying cause of ESRD, diabetic duration, height, weight, body mass index (BMI) [BMI = weight (kg) /height (m2)], presence of comorbid diseases such as hypertension, cardiovascular disease (CVD), blindness due to diabetic retinopathy, chronic pulmonary disease and malignancy. CVD was defined as a previous history of coronary artery disease, peripheral vascular disease or cerebrovascular disease. The baseline laboratory parameters were collected as follows: fasting plasma glucose, hemoglobin, serum albumin, corrected calcium, phosphate, intact parathyroid hormone (iPTH) and lipids. Baseline dialysis adequacy data included urine output, ultrafiltration volume, residual renal function (RRF), and indices of urea kinetics (Kt/Vurea) and creatinine clearance (CrCl) for both peritoneal and residual renal function. RRF was calculated by the mean of renal clearances of urea and creatinine from a 24-hour urine collection. Peritoneal transport characteristics were measured by the dialysate to plasma creatinine ratio (D/Pcr) at 4 hour in a standard peritoneal equilibration test. Other clinical data were also obtained as follows: blood pressure, PD regimen, dialysate glucose exposure (calculated from the dialysis regimen as described by Davies et al ), dialysate glucose absorption (total dialysate glucose absorption per day = (1-D4/D0) × total glucose exposure per day, as described by Donna M. Bodnar et al ), normalized protein nitrogen appearance (nPCR) (from 24-hour dialysate and urine collections), records of taking angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARBs), steroid therapy and insulin.

Next, the normalized data was subjected to one-way ANOVA and a list of filtered genes with 19,767 probes which passed the significant unadjusted p-value ≤ 0.05 and difference in the methylation levels between the PG and HG groups of hNPCs more than of ± 0.5 criteria, was created (Supplementary Dataset S1). Some miRNAs and L-ncRNAs with altered DNA methylation at parent sequence in the hNPCs exposed to HG condition were also found in the list of probes. Further, a heat map was generated on hierarchical clustering using top 12,087 differentially methylated probes in hNPCs exposed to HG (Fig. 2b). The gene ontology (GO) enrichment analysis from hNPCs exposed to HG based on cellular component, molecular function and biological processes revealed that: (a) genes involved in cellular junction, cytoskeleton and synapse were highly enriched in cellular component; (b) genes involved in binding and catalytic activity, including actin binding were enriched in molecular function; (c) genes involved in developmental process, axon guidance, metabolic processes and cell differentiation were highly enriched in biological processes (Supplementary Fig. S1, Supplementary Dataset S2). These findings indicate that HG alters DNA methylation pattern in genes regulating developmental processes in hNPCs. We have also used the minfi package32 to analyse the data (Supplementary Dataset S4) which were further subjected to pathway analysis using Ingenuity Pathway Analysis (IPA) software.
