Rétinoblastome: Le rétinoblastome est la tumeur intraoculaire la plus commune de l'enfance, 90% des cas surviennent avant l'âge de 5 ans rejoignant ainsi nos résultats. La leucocorie est le signe le plus fréquent du rétinoblastome, suivi par le strabisme ; dans notre étude, le signe le plus fréquent était l'exophtalmie. L'imagerie radiologique peut être utilisée pour confirmer le diagnostic et déterminer la stadification. Sur l'échographie, il peut s'agir d'une petite tumeur solide reliée à la rétine, bien limitée; ou bien une masse irrégulière qui est plus échogène que le vitrée et contient des calcifications d'ombrage, qui dans ce cas, peuvent être détectées jusqu'à 95% des cas en échographie orbitaire; on peut aussi voir un décollement de rétine ou une hémorragie . Ces résultats concordaient avec les notres. L'échographie ainsi peut confirmer le diagnostic clinique du rétinoblastome . Le scanner montre généralement une masse contre la paroi postérieure avec ou sans décollement rétinien, des calcifications uniques ou multiples en mottes rejoignant ainsi l'aspect fréquemment retrouvé dans notre série, ou parfois une tumeur disséminée dans le vitré, parfois des lésions hyperdenses avec un rehaussement intense après injection du PDC. Il peut également établir le bilan d'extension locorégional et à distance. L'IRM évite le rayonnement ionisant du scanner et est plus sensible pour la détection de l'extension extra et péri-oculaire de la maladie, la propagation péri-neurale dans le nerf optique et l'implication de l'espace sous-arachnoïdien ainsi que l'étude du parenchyme cérébral, en particulier de la région pinéale à la recherche d'un rétinoblastome trilatéral , retrouvé chez un patient de notre série. Il s'agit d'une masse en iso ou hypersignal en T1, hyposignal en T2 (Figure 2), avec prise de contraste hétérogène. De ce fait, l'IRM est l'examen de choix d'évaluation et de suivi pour les cas connus de rétinoblastome avec des symptômes cliniques de propagation extra-oculaire .

In science and engineering there exist a lot of nonlinear differential equations and even strongly nonlinear problems which are still very difficult to solve analytically by using traditional methods. Many methods exist for approximating the solutions of nonlinear problems, for example, the Adomian decomposition method , the modified Lindstedt-Poincare method , the parameter-expansion method , optimal variational method , optimal homotopy perturbation method , and so on .

O uso de ferramentas de análise espacial em saúde pública ajuda a fomentar a discussão sobre o espaço e a heterogeneidade dos fenômenos populacionais nele distribuídos, auxiliando no reconhecimento de áreas com características socioambientais mais semelhantes entre si e identificando locais de maior vulnerabilidades e risco à saúde (4, 5). Em razão da importância da distinção de áreas prioritárias para ações em saúde pública, o presente estudo tem como objetivo apresentar um método simples, desenvolvido para identificar áreas críticas quanto à incidência de doenças infecciosas e parasitárias selecionadas, analisando a associação ecológica entre a ocorrência dessas doenças e indicadores de pobreza no Brasil.

Für das therapeutische Vorgehen empfiehlt sich ein Algorithmus, um das Risiko evtl. Komplikationen oder Folgeschäden zu minimieren (Abb. 8). Dieser sollte jedoch lediglich als Orientierung dienen, da im Einzelfall adaptiert an den Anspruch des Patienten in Bezug auf die körperliche Belastbarkeit unbedingt eine individualisierte Therapieentscheidungindividualisierte Therapieentscheidung getroffen werden muss. Nach der orientierenden Anamneseerhebung, der fokussierten klinischen Untersuchung mit obligater Testung des peripheren neurovaskulären Status sollte schnellstmöglich die Röntgenuntersuchung folgen. Die Richtung der Ellenbogenluxation ist entscheidend für die richtige Reposition. Bei einer Luxation ohne Frakturbeteiligung ist das Hauptziel die sofortige geschlossene Repositiongeschlossene Reposition zur Erlangung der vollständigen Gelenkkongruenz, sodass eine frühfunktionelle Beübungfrühfunktionelle Beübung möglich ist. Im Allgemeinen lässt sich die einfache Ellenbogengelenkluxation gut in einer Kurznarkose reponieren. In Abb. 7a–d sind zwei etablierte und im eigenen Vorgehen favorisierte Techniken zur Reposition einer posterolateralen Luxation dargestellt. Anschließend eignet sich v. a. die Stabilitätstestung in Narkose zur klinischen Untersuchung nach der Reposition (Abb. 7e–l sowie die zuvor beschriebene Stabilitätstestung unter Durchleuchtung). Ereignet sich bei der Stabilitätsprüfung keine Reluxation im endgradigen vollen Bewegungsausmaß, kann bei fehlenden pathologischen radiologischen Kriterien und unauffälligen klinisch-radiologischen Verlaufskontrollen eine konservative Therapiekonservative Therapie gebahnt werden (Abb. 8). Im Fall von Luxationen zwischen endgradiger Extension und 30°-Flexion sind eine engmaschige klinische Reevaluation und die Durchführung einer MRT richtungweisend. Einige Autoren tendieren mittlerweile auch hier zur frühzeitigen operativen Stabilisierung . Bei Reluxation im funktionellen Bogen, einer persistierenden Subluxationsstellung oder intraartikulären pathologischen Veränderungen sollte in jedem Fall eine zeitnahe operative Versorgungoperative Versorgung durchgeführt werden .

PFS and OS were calculated from the date of the last chemotherapy treatment/diagnosis to the date of recurrence/death or last follow-up, respectively. Univariate survival analyses of PFS and OS were executed using the Kaplan-Meier method and log-rank test. Platinum resistance was defined as PFS ≤ 6 months according to guidelines published by the Gynecologic Oncology Group (GOG) and progressive disease or recurrence was evaluated by the RECIST criteria . Multivariate analysis was performed using the Cox Regression Model (Enter function).

A relationship between aneurysms and the HIV infection has been documented in vascular series,13 in which aneurysms have been found to be multiple and occur in unusual anatomical locations. In our cases, the root abscesses and leaflet aneurysms were larger in size in the HIV-positive patients. None of our patients had evidence of mycotic aneurysms elsewhere, which has been reported more frequently when presentation is delayed, especially in developing countries.14

The percentage of the probability bets in each choice pair (Table 1) is consistent with our prediction. To illustrate, in Pair 1, 62% of the participants prefer the probability bet in the compressed probability distance condition. However, the choice percentage increases to 73% in the compressed money distance condition.

The majority of participants reported a current psychiatric condition, with patients meeting criteria for two diagnoses on average. However, it should be noted that 16.7% of the participants did not meet criteria for any current psychiatric conditions. This result suggests that there likely exists a group of individuals with FA who may not meet criteria for a recognized eating disorder or other psychiatric condition, yet still experience psychosocial impairment severe enough to warrant seeking treatment. Addictive disorders were not very common in the sample, which is surprising given the conceptualization of FA as an addiction and given that addictive disorders tend to co-occur . Additionally, FA was not related to cravings, which is also a hallmark symptom of addictive disorders. A potential reason for this finding may be due to the relatively small sample size as the association between FA and craving was approaching significance with close to a moderate effect size (p = 0.087, r = 0.26). Thus, future research with large samples is needed to further investigate the association of FA with other addictive behaviors, to examine whether they are likely to co-occur, and whether FA is associated with hallmark characteristics of addictive disorders such as heightened levels of impulsivity.

The identification of bat species can be important to understanding rabies transmission. The behavior of some species can expose them more or less to the virus . Tadarida brasiliensis, Molossus rufus, and Molossus molossus (species identified in this study) form maternal colonies, which may push males to competition and segregation and make females have more body contact [40, 41]. Spatially, the Molossidae family (insectivorous family in general) may be attracted to insects near urban artificial lights and may find artificial shelters in roofs, ceilings, attics, etc. [42, 43]. This is reflected in the study at hand, where the highest bat capture was at the central-northern region, the high human population density of the city, providing artificial shelters and food supply [6, 44].

The flower extract of Senna auriculata (L.) Roxb. has also been reported for its salutary effect on hepatic enzymes involved in the carbohydrate mechanism. The flower extract (450 mg/kg body weight) was found significant when compared with the standard drug, glibenclamide (600 µg/kg body weight) in increasing the hexokinase activity and decreasing the gluconeogenic enzyme activity in STZ-induced diabetic rats. The increased plasma insulin level in flower extract-fed diabetic rats was responsible for the modulation of hepatic carbohydrate metabolic enzymes (Latha and Pari, 2003a; Latha and Pari, 2003b).

L’eccesso di glucocorticoidi è associato a un fenotipo metabolicamente compromesso, caratterizzato da obesità centrale, insulino-resistenza e diabete. Nella sindrome di Cushing è stata riscontrata una prevalenza di steatosi epatica non trascurabile, di circa il 20%, significativamente correlata al tessuto adiposo viscerale . Uno studio ha osservato che i pazienti affetti da NAFLD presentavano una lieve iperattività dell’asse ipotalamo-ipofisi-surrene, e il cortisolo libero urinario delle 24 ore e il cortisolo dopo soppressione con 1 mg di desametasone risultavano essere predittori indipendenti di NAFLD e della severità della fibrosi epatica .

组织发生部位是肿瘤的重要特征之一，主支气管和肺由原基（肺芽）向各级气管及肺泡分化的过程中存在特定表型特征的逐步关闭和表达，而这种变化又和部位存在一定关联性。如在胚胎早期TTF-1的表达可见于大气管的假复层纤毛柱状上皮中，而在发育成熟的个体中仅见于肺泡单位和远端呼吸性细支气管中，可见肺癌的组织发生部位或组织起源代表了肺癌的表型和分化特征。本研究中不同组织起源的肺癌与相对应的正常肺组织免疫表型呈现高度的一致性；同时单因素生存分析显示，临床Ⅰ期和Ⅱ期的细支气管肺泡癌患者的预后趋势优于支气管上皮癌但低于肺泡细胞癌，因为大多数的患者在术后接受了放化疗或靶向治疗，目前基于顺铂为主的联合治疗方法多用于NSCLC患者不同阶段的治疗。不同的临床预后也从另一方面反映出不同起源NSCLC对于治疗方案的选择存在明显差异。以上分析表明，本研究提出的肺癌分类不但具有很高的病理分类诊断价值，也具有重要的临床治疗指导意义。

Approximately 30% of neurons in the dmPFC and the VTA encoded the experience of animals receiving food reward or the tail pinch stressor. This substantial proportion of neurons in the dmPFC and the VTA that encode opposing valence experiences (dual-valence neurons) could function as mixed selectivity neurons. Mixed selective neurons have been implicated in processing different sensory or motor variables and can facilitate contextual flexibility during cognitive and motor behavior (Rigotti et al., 2013; Kobak et al., 2016; Ma et al., 2016). Mixed selective neurons are prevalent in the PFC (Rigotti et al., 2013; Grunfeld and Likhtik, 2018). While VTA neurons are often assumed to be specialized, recent studies have suggested that clusters of DA neurons respond to a whole array of variables in addition to reward (Engelhard et al., 2019). Dual-valence neurons in the dmPFC and the VTA could fine-tune adequate behavioral outcomes depending on the emotional context (i.e., degree of averseness; Matsumoto et al., 2016; Park and Moghaddam, 2017; Berridge, 2019). Alternatively, dual-valence neurons may facilitate learning by adapting their response to only one type of experience (aversive or rewarding) after repeated exposure (Li et al., 2017). Future studies are needed to establish which common input onto these neurons drives this activity. Possible regions include bed nucleus of the stria terminals, hypothalamus, and amygdala (Burgos-Robles et al., 2017; Morales and Margolis, 2017; Ch'ng et al., 2018).

Cell proliferation, migration, colony formation and wound healing assays were performed to evaluate the biological functions of the target genes. In brief, for cell proliferation, PSCC cells (2×103/well) were seeded into 96-well plates with 100 μl medium, mixed with 10 μL CCK-8 solution (Dojindo, Japan) and incubated for 2 h. The cell number was counted by the optical density (OD) value at an optimal wavelength of 450 nm on an Infinite F50 microplate reader for 7 consecutive days. For cell migration, 105 cells were cultured in 300 μl serum-free DMEM and seeded into the upper compartment of a 24-well transwell culture chamber, and 750 μl DMEM supplemented with 10% serum was added to the lower compartment. Migrated cells were counted after incubation for 24 h. For colony formation, PSCC cells (1×103/well) in 6-well plates were cultured for 10 days and fixed with 4% paraformaldehyde for 30 min. The number of colonies was counted by ImageJ (National Institutes of Health, USA) after staining with 0.5% crystal violet. For wound healing, cells were seeded into 6-well plates after growing to confluence, and cross wound lines were made with a 1000-μl pipette tip. Then, the cells were cultured in serum-free DMEM for 16 h, and the wound healing area was recorded. All the experiments were repeated in triplicate.

Mean ± standard error of the mean (SEM) of data is reported throughout the text. Hypothesis testing was performed as indicated with either analysis of variance (ANOVA) followed by appropriate post hoc tests or two-sided, unpaired, unequal variances t-tests. Statistical tests were performed in Python 2 or 3 with the SciPy, pandas and Pingouin (Vallat, 2018) packages. Unless otherwise noted, all data shown reflect at least three biological replicates (independent cultures measured on different days). Each of these biological replicates contained between 1 and 5 technical replicates (different samples of cells that were measured on the same day and had been prepared from the same cell stock). For tandem electrophysiology-FLIM measurements, each τfl-Vmem calibration includes at least three biological replicates to capture the variability expected during applications of VF-FLIM. No power analyses were performed before data were collected. Sample sizes throughout the text refer to the total number of cells or cell groups of a given type analyzed across all biological and technical replicates. Cell group identification is discussed in Methods. For experiments where resting membrane potential or resting membrane potential changes are compared to a baseline (Figures 3–5 and supplements), both control measurements and their physiologically or pharmacologically altered counterparts were recorded on each experimental day. Masking was not used during data collection or analysis.

Previous studies have shown that introns are common in the ribosomal protein genes (e.g., RPL7) of intron-poor protozoa and saccharomycetous yeasts (Bon et al. 2003; Russell et al. 2005; Franzén et al. 2013). However, the abundance of introns in other classes of genes is less well-known. We examined the gene ontology (GO) terms of the orthologs of the intron-poor species. We found that introns are highly abundant not only in genes involved in cytoplasmic translation (e.g., ribosomal proteins) but also in genes involved in proton transport and endosome organization (fig. 8 and supplementary fig. S6, Supplementary Material online). In contrast, introns are depleted in genes involved in protein folding and small molecule biosynthetic processes. The reasons for these biases are worth further exploration.

关于同期多原发肺癌的诊断，目前主要依据Martini标准(M -M标准)和ACCP指南。1 9 7 5年Martini和Melamed率先建立了同期多原发肺癌的临床病理诊断标准，包括：(a)肿瘤部位不同且相互独立；(b)组织学类型不同；(c)组织学类型相同，但位于不同的肺段、肺叶或双侧肺，起源于不同的原位癌，共同的淋巴引流区域无癌，无肺外转移。随后，在2013年ACCP指南对其做了更新，具体为：(a)组织学类型不同，分子遗传学特征不同，或起源于不同的原位癌；(b)组织学类型相同时，肺癌位于不同肺叶，且无N2、N3转移，无远处转移。分子生物学检测对诊断同期多原发肺癌有了很大的提高，如克隆分析(clonality analysis)、杂合性丢失(loss of heterozygosity)等，但也同样面临着挑战，如肿瘤细胞内在异质性。

We performed nanopore sequencing of DNA extracted from 30 adult females of strain DGRP-732 from the Drosophila Genetic Reference Panel (DGRP)(Mackay et al. 2012)(Table S1). We assembled the nanopore data using Canu (Koren et al. 2017), scaffolded the Canu contigs with Hi-C data using the 3D-DNA pipeline (Dudchenko et al. 2017), and polished the scaffolds using Racon (Vaser et al. 2017) and Pilon (Walker et al. 2014). We obtained contig/scaffold N50 values of 5.4 Mb and 25.7 Mb, respectively and identified one-to-one alignments between our assembly and the D. melanogaster iso1 reference genome (Hoskins et al. 2015) that encompassed 98% of the iso1 assembly. The assembly has been deposited in the NCBI whole genome shotgun (WGS) database (BioProject PRJNA515844) and will be described in more detail in another manuscript (Ellison & Cao, in prep).

In most cases, males allocated the sperm load of one palp into two portions although more or less portions are possible. A congener, N. clavipes, also known to reuse pedipalps despite sperm limitation , deplete their sperm supply with virgin females while this occurred very rarely in N. senegalensis. Indeed, the length of the first copulation determined how many portions are left for future copulations with the same pedipalp. Here we suggest that N. senegalensis show a prudent use of their sperm supply during their first copulation and always retain a quantity of their limited sperm supply for future copulations.

(A) HORMAD1 was co-immunolabelled with RAD21L or REC8 on spread chromatin of WT preleptotene spermatocytes (upper). For visualization, green channels were shifted to the right by three pixels in the magnified views (middle). Preleptotene cells were identified by patchy EdU labelling pattern that represents late S phase (lower small panel) and by punctate cohesin staining. Note that slight difference in the localization pattern of RAD21L on the chromatin have been observed among previous studies . This difference could be due to the sensitivity and/or cross reactivity with RAD21 of the antibodies used. (B) The number of the immunolabelled dotty signals of RAD21L, REC8 and HORMAD1 are shown in scatter plots. The numbers of the cells observed are shown below the graph. Red bars indicate mean and SD. (C) Quantification of HORMAD1 dots that overlapped with RAD21L or REC8 dots (left), and RAD21L or REC8 dots that overlapped with HORMAD1 dots (right) are shown in bar graphs with SD. To show these were not random overlaps, the co-localization was measured without (black plot) or with (blue plot) rotation of the HORMAD1 image by 90° clockwise relative to the cohesin images. Co-localization was measured by ComDet plugin for ImageJ (see Methods). Co-localization was assessed by two criteria, either < 1 pixel distance or < 3 pixel distance. Statistical significance was assessed by one-way ANOVA followed by Turkey’s multiple comparisons test with a single pooled variance. ***: P < 0.001. The numbers of the cells observed are shown below the graph. Red bars indicate SD. (D) Super-resolution imaging of spread chromatin using N-STORM microscopy showed that HORMAD1-enriched domains (magenta) and the cohesins RAD21L- and REC8-enriched domains (green) were localized side by side. Scale bars: 10 μm unless indicated. (E) Immunolabeling of HORMAD1, REC8 and RAD21L on stretched chromatin fibers of preleptotene/leptotene WT spermatocytes confirmed that HORMAD1, REC8 and RAD21L were loaded onto the chromatin. DNA fiber was labelled with DAPI. (F) HORMAD1 was co-immunolabelled with RAD21L or REC8 on spread chromatin of Sycp2-KO preleptotene spermatocytes (upper). For visualization, green channels were shifted to the right by three pixels in the magnified views (middle). Scale bars: 10 μm. (G) Quantification of RAD21L dots that overlapped with HORMAD1 dots (left), and HORMAD1 dots that overlapped with RAD21L dots (right) in WT and Sycp2-KO preleptotene spermatocytes are shown as in (C) (left graph). Quantification of REC8 dots that overlapped with HORMAD1 dots (left), and HORMAD1 dots that overlapped with REC8 dots (right) in WT and Sycp2-KO preleptotene spermatocytes are shown (right graph). Co-localization was assessed by < 3 pixel distance. Statistical significance was assessed by one-way ANOVA followed by Turkey’s multiple comparisons test with a single pooled variance. * P < 0.05. ** P < 0.01. ***: P < 0.001. The numbers of the cells analyzed are shown below the graph. n.s.: not specific. Back bars indicate mean and SD.

In Fig. 8, we show the evolution of the reflectivity spectra, as in Fig. 7, for a PSi sample grafted with eight CV cycles. In this case, it is clear that there is a significant improvement with respect to the five CV cycles grafting: after 38 min, the PSi structure is only slightly modified. Further increasing the number of cycles does not improve significantly the chemical resistance, even if the reduction peak is visible up to the 12th cycle.Fig. 8Evolution from the reflectivity of PSi grafted with eight CV cycles and immersed in NaOH 0.5 M. The spectra, to ease their comparison, are vertically shifted with respect to each other by a 25 % amount. The bottom spectrum has no vertical shift

For the words notation, there was a main effect of condition, F(1, 18) = 22.12, p < 0.001, ηp2 = 0.55, suggesting that the experimental condition yielded higher oddballs than the control condition, pbonf < 0.001, d = 1.08. There was also a main effect of electrode side, F(1.48, 26.55) = 7.21, pGG = 0.006, ηp2 = 0.29, suggesting higher amplitudes for LOP side compared to both ROP, pbonf = 0.006, d = 0.77, and MO sides, pbonf = 0.008, d = 0.74. The ROP and MO electrode sides did not differ from each other, pbonf = 1.00, d = −0.03. There was also a condition × electrode side interaction, F(2, 36) = 4.76, p = 0.02, ηp2 = 0.21. Post hoc comparisons (Bonferroni correction applied) showed that experimental condition yielded significantly higher peaks than the control condition within the LOP, pbonf < 0.001, and the ROP, pbonf = 0.03, electrode sides, but not in the MO side, pbonf = 0.09. Furthermore, the experimental condition within the LOP side yielded higher amplitudes then the experimental condition in ROP side, pbonf = 0.002. This was not the case for the control condition comparisons, pbonf = 1.00.

La TBL est une prolifération épithéliale condylomateuse d'origine virale dont le génie évolutif est incertain avec un risque de transformation en carcinome épidermoide. Sa prévention est impérative basée sur le traitement des condylomes acuminés et la lutte contre les maladies sexuellement transmissibles. Le traitement doit être précoce, il est essentiellement chirurgical nécessitant une large exérèse. Une surveillance postopératoire clinique et histologique étroite et prolongée s'impose, sans perdre de vue la notion de dégénérescence de la récidive.

Spectra were recorded in reflection mode on a Bruker IR spectrometer (tensor 27) coupled to an IR microscope (Hyperion 2000) with 36x magnification. The data of the effect of variation of the composition and distribution of the biochemical components in bacterial cells during cell culture were analyzed using principal component analysis (PCA). All data analysis was carried out in the spectral range from 3000–2800 cm−1 to 1800–850 cm−1, which covers the fingerprint region [42–45]. The average peak area and intensity at each region were obtained from three independent examinations; each examination was done in triplicate.

This study has several limitations. First, the patient population was relatively small. Second, the overall impact of different kinds of fatty acids on the vascular bed had not been clearly clarified. Third, as we excluded patients with obvious organ dysfunction and emergency surgery, the potential selective bias could not be completely avoided.

Os avaliados foram alocados, de maneira aleatória, por sorteio dos nomes em envelope opaco, em quatro subgrupos de cinco indivíduos (Grupos A, B, C e D). Dentro dos subgrupos, os voluntários recebiam a mesma frequência de estimulação, havendo mudança de frequência de acordo com a semana do experimento (Tabela 1). Os 20 voluntários passaram pelas diferentes formas de eletroestimulação: TENS 1 (GT1 – 0Hz), TENS 2 (GT2 – 7Hz), TENS 3 (GT3 – 100Hz) e TENS 4 (GT4 – 255Hz), com avaliações divididas em quatro momentos: pré-aplicação, pós-aplicação, 20 minutos e 60 minutos após a eletroestimulação.

It is interesting to compare our model for FtsWI activation with the model proposed for activation of the RodA-PBP2 pair that are part of the elongasome (homologous to FtsW-FtsI [PBP3]). That model is based upon (i) the structure of the MreC-PBP2 complex (32) and (ii) the finding that mutations that bypass mreC and activate RodA-PBP2 map to the nonpenicillin (nPD) or pedestal domain of PBP2 (33). It is thought that these mutations mimic the binding of MreC to PBP2, altering the conformation of PBP2, which results in the activation of RodA. In this way, the activity of RodA and PBP2 are coupled to ensure RodA only makes glycan strands when its cognate PBP is present. This is remarkably similar to our model for FtsW-FtsI (PBP3) activation with FtsL (with possibly a supporting role for FtsB) being analogous to MreC. The isolation of FtsW activation mutants that bypass FtsN suggests that an activated FtsW results in an active FtsI. Furthermore, an active FtsW mutant can rescue dominant negative FtsL mutants (i.e., bypass the signal from FtsN), indicating FtsI is also activated. Thus, we propose that FtsN action alters the conformation of FtsQLB so that AWI becomes available to interact with FtsI, leading to conformational change in FtsI that activates FtsWI’s enzymatic activities.

When a meniscal cyst was concurrently found with the anterior horn tear, the decompression could be carried out through the inframeniscal portal before resecting the inferior leaf of the meniscus. The scope was advanced through the anterolateral portal to visualize the synovium anterior to the root of the meniscus, and a 2.5 mm shaver was brought through the anteromedial portal to make a 1 cm incision on the synovium, which is part of the cyst in most cases (Figure 2(e)). Then, the scope was transferred to the anteromedial portal, and the shaver was passed through the inframeniscal portal to trim the inferior part of the cyst under direct visualization with the scope. The connection between the superior meniscus and the joint capsule was preserved. The resection of the inferior leaf of the meniscus was carried out as described previously.

Camptothecins are potent radiation sensitizers, because DNA topoisomerase I recently has been established as a biochemical mediator of radiosensitization in cultured mammalian cells by camptothecin derivatives. Interestingly, this sensitization appears to be schedule-dependent, cell cycle phase-specific, and not strictly drug cytotoxicity-dependent . Despite the fact that there are data arguing against topo I expression level as a critical determinant of cell sensitivity to camptothecin in unselected human cancer cell lines , topo I activity has been found elevated in primary cervical cancers compared with normal cervix; in addition, combined treatment of sub-or post-confluent CaSki cells with camptothecin and ionizing radiation results in additive killing of cells .

Based on morphological variations and discontinuous distributions, R. roxellana is distinguished into 3 subspecies: R. roxellana roxellana from the Minshan Mountain in the Sichuan and Gansu Provinces, R. roxellana qinlingensis from the Qinling Mountain in Shaanxi Province, and R. roxellana hubeiensis from Shennongjia Mountain in Hubei Province . Recent studies of R. roxellana have focused on behavioral dynamics, population history, and social systems [5–7]. To date, only a single genome assembly is available for the golden snub-nosed monkey. This assembly, published in 2014, was derived from short sequencing reads generated by the Illumina HiSeq 2000 platform . Several studies have been published based on these data, including analyses of the folivorous dietary adaptations of R. roxellana and its evolutionary history [8–10]. Despite the utility of these previously published data, much relevant information, including structural variations and repeat sequences, is largely absent or unreliable owing to the incomplete and fragmented genome assembly [11, 12].

Data were handled using SPSS and Stata (version 11, StataCorp, College Station, Texas). First, descriptive statistics and differences in QoL ratings between pairs of raters were calculated. To determine the significance and magnitude of the influence of predictor variables on QoL ratings by patients, family informants and RCF further analyses were conducted on the subset of data from people able to self rate. We calculated the mean difference, between PWD able to self rate QoL with, and without, each candidate predictor variable and the respective 95% confidence interval (95%CI) for the difference. “Pain reported” was defined as a positive response to the first question in the Brief Pain Inventory (“Throughout our lives, most of us have had minor aches and pains from time to time. Have you had pain, other than these everyday kinds of pain, today?”), “Pain observed” was defined as a score of greater than one on the PAIN-AD scale. “Increasing weight” was defined as most recent weight greater than previous weight recording in the last 6 months. Presence of “neuropsychiatric symptoms” was defined as NPI-NH score >14 and “staff distress” as a care giver distress score>4 on the NPI-NH. Other non-categorical predictor variables were categorized at a clinically accepted point (eg MMSE <10). Finally, to determine whether associations between predictor variables and quality of life rating were independent of each other we constructed parsimonious regression models, for both self rating of the QoL-AD, and staff informant rating of the ADRQL. This commenced with a series of univariate models (in which continuous variables were evaluated as such) to identify all candidate predictor variables. Variables with p<0.1 were then included in a multivariate regression model and removed using a backward stepwise process if their significance was not retained, until all remaining variables had p<0.05. We set alpha at 5% and all p-values reported are two-sided.

奥希替尼是新一代不可逆性EGFR-TKI，对EGFR敏感突变和T790M耐药突变均有更好的作用。2016年发表的Ⅱ期临床AURA2试验最新数据显示，应用奥希替尼80 mg qd治疗EGFR-TKI治疗后进展T790M突变阳性的210例Ⅲb期/Ⅳ期NSCLC，截至2015年11月，140例/199例（70%）达到客观缓解，其中CR 6例，PR 134例。最常见的3级/4级不良事件为肺栓塞7例（3%），心电图上的QT延长5例（2%），中性粒细胞计数下降4例（2%）。52例（25%）患者发生严重不良事件，研究者评估11例（5%）可能与奥希替尼治疗相关，唯一治疗相关致死事件为间质性肺病。由于奥希替尼用于T790M阳性的NSCLC治疗的疗效非常确切。美国食品和药物管理局（Food and Drug Administration, FDA）在2015年11月13日以加速批准的方式提前3个月批准了奥希替尼用于治疗EGFR-TKI治疗中或治疗后出现进展并伴有EGFR T790M阳性突变的NSCLC患者。2016年WCLC公布了奥希替尼对比铂类联合培美曲塞化疗治疗经一线EGFR-TKI治疗后进展的NSCLC的随机Ⅲ期临床研究结果。该项研究（AURA3）共纳入419例患者，2:1随机分配至治疗组（奥希替尼80 mg/d，n=279）和铂类联合培美曲塞化疗组（n=140）。入组患者均为组织活检确认T790M突变，一线EGFR-TKI治疗后影像学进展。主要研究终点为PFS。结果显示奥希替尼组较培美曲塞化疗组PFS明显改善（HR=0.30），分别为10.1个月vs 4.4个月，ORR也明显优于化疗组，分别为71% vs 31%（OR=5.39），中位缓解持续时间奥希替尼组达到9.7个月，而化疗组仅为4.1个月。奥希替尼最常见的相关不良反应为腹泻（29%）和皮疹（28%），≥3级治疗相关不良事件发生率为6%（n=16），明显低于化疗组34%（n=46）。该项研究结果更充分证实了奥希替尼治疗一线EGFR-TKI治疗失败且T790M突变阳性的晚期NSCLC患者，疗效优于化疗，且安全性可靠，据此为患者的临床治疗建立了新的标准。该项研究结果已同步发表在The New England Journal of Medicine杂志上。而关于奥希替尼在T790M突变的东亚晚期NSCLC患者的Ⅱ期开放性研究（AURA17）结果也在2016年WCLC大会上有初步的报道。截至2016年3月4日，共入组171例患者，其中166例疗效可评价，中位治疗时间5.6个月。经独立评审中心（BICR）确认的ORR和疾病控制率（disease control rate, DCR）分别为60%和88%，中位DCR和PFS还未成熟，最常见的AE发生率以及≥3级以上AE发生率分别为腹泻（29%, 0）、皮疹和痤疮（20%, 0）、皮肤干燥（17%, 1%），3例患者报道有间质性肺病。这一结果与全球研究结果相似，是未来奥希替尼在中国注册临床的重要试验。

Chronic liver diseases associated with deranged lipid metabolism constitute a major part of the metabolic syndrome . Nonalcoholic fatty liver disease (NAFLD), also known as metabolic associated fatty liver disease (MAFLD) , has become a global epidemic and is associated with other metabolic disorders, such as diabetes and obesity . Given the paucity of treatment options available for NAFLD, there has been a surge in understanding the molecular mechanism of this disease . Studies show that “lipotoxicity” is the central driving force that governs the progression of NAFLD from being a state of benign lipid accumulation to a state of lipid-induced liver damage and inflammation termed non-alcoholic steatohepatitis “NASH” . Lipotoxicity at a cellular level involves perturbation in the function of several intracellular organelles, namely, mitochondria, endoplasmic reticulum (ER), and lysosomes, induced by nonesterified fatty acids or free fatty acids (FFAs), particularly those derived from saturated fats . Autophagy is a cellular cytoprotective process, which is not only affected by lipids but also acts to mitigate the effect of lipotoxicity in animal models of NAFLD . Autophagy inducers have shown to limit the abundance of FFAs by increasing their sequestration into triglycerides (TAGs), increasing their oxidation, and preventing the damage of intracellular organelles . This review covers autophagy–lipid crosstalk and its implication in countering lipotoxicity.

Mouse models of uremia are important tools for in vivo translational studies such as examining the impact of specific genes in transgenic or knockout mice and to validate potential therapeutic interventions prior to pre-clinical testing in humans. The limitations of existing surgical models of uremia in mice, including requirements of surgical skills, demand of animal facilities to support post-operative care, high mortality rate and less flexibility in terms of dynamic alterations in urea levels, prompted us to develop a non-surgical model of renal dysfunction based on dietary intake of adenine. This approach has successfully been used in rats but not in mice because of their reluctance to consume adenine. Accordingly, addition of adenine to a standard mouse chow elicits high morbidity and mortality due to starvation and malnutrition rather than renal failure. In our model, this was circumvented by mixing the adenine in a casein-based chow, in which the casein effectively removed the inherent smell and taste of adenine.

A measurement is a process of experimentally determining one or more values that can reasonably be attributed to the selected quantity . When we perform a measurement, we get an observation Y, based on which, we can identify the value of the measurand X. The description of the sensor sub-process is provided by the conditional probability distribution (1)p(y|x) that is, the probability distribution of Y, given the value x of the measurand X. The accuracy of the probability distribution (1) depends on the sophistication of the sensor design, protection against environmental factors, and on the removal of method errors.

Les données épidémiologiques concernant les accidents domestiques de l´enfant ne peuvent être valablement considérées comme le reflet du phénomène accidentel parce qu´elles ne représentent qu´une petite partie du problème , en faite ces accidents se produisent toujours dans l'indifférence quasi généralisée, tant des autorités de santé que du grand public dans notre cotexte de pays en voie de développement où l'intérêt en matière de pathologie accidentelle est donné surtout aux accidents de la voie publique. Et pourtant, on assiste à une augmentation très importante de la prévalence de ces accidents qui constituent un sérieux problème de santé publique dans le monde entiers, c'est ainsi que sur le plan européen, le programme EHLASS, vise depuis 1981 à établir un système harmonieux pour le recueil et l´échange des données sur les AcVC . Au Maroc la documentation et la littérature concernant les aspects épidémiologiques, évolutifs et préventifs des accidents domestiques de l'enfant sont très pauvres, ce qui contribue significativement à l'insuffisance profonde constatée en sources d'informations. Sur une année, nous avons pu colliger 108 cas d'accidents domestiques graves sur 698 admissions (soit 15,5%) au service de réanimation pédiatrique de l'hôpital d'enfants de Rabat(Maroc) avec 16décès (soit 14,8% des accidents domestiques); la prévalence et la mortalité des accidents domestiques de l'enfant varient considérablement d'un pays à l'autre. selon l'enquête permanente sur les accidents de la vie courante 2000-2003 en France, on estime, que les moins de 15ans sont victimes chaque année de 1,5 à 2 millions d'AcVC avec recours aux urgences hospitalières . En Afrique, l'incidence est également élevée: 381cas en l'an 2000 en Algérie et 1800 cas en un an à l'hôpital de Sfax en Tunisie [5, 7], pour Ka et al. au Sénégal, la pathologie accidentelle constitue 3% des causes d'hospitalisation des enfants de 0 à 15ans, quant à Mbika-Cardorelle et al. , ils rapportent une fréquence de 2,8% des admissions dans l'unité de soins intensifs pédiatrique du CHU de Brazzaville (Congo).

On the Γ−K−M plane, the calculated bands clear show two sets of kagome bands originating mainly from in-plane dxy/dx2−y2 (red) and out-of-plane dxz/dyz (green) orbitals, respectively. The two cones are very close and the flat band with dxz/dyz orbitals characters is more prominent along the Γ−M lines, which are consistent well with the ARPES measurements. Besides, the electron-like band touching with the flat bands at the Γ point extends to the K point and forms Dirac cone above EF, as discussed in Fig. 3. On the A−H−L plane, the cone with dxy/dx2−y2 orbitals characters ascends, and the cone with dxz/dyz orbitals characters descends to higher binding energy. Under the protection of time-reversal and spatial-inversion symmetry (T ⋅ P symmetry), the two cones at the K point form two nodal lines along kz direction when the SOC is neglected (Supplementary Fig. 5). With the inclusion of SOC, the two cones open gaps with energy of ~96.5 meV (dxy/dx2−y2) and ~8 meV (dxz/dyz) in the DFT calculations (Fig. 4b), respectively. The strengths of SOC of in-plane orbitals are much stronger than those of out-of-plane orbitals, indicating the orbital-selective character of the SOC strength. The dz2 (blue) orbital mainly contributes a set of kagome band at a higher binding energy around kz ~ π plane, showing a strong three-dimensional character.

Male flies were collected less than 72 hours post eclosion and anesthetization on ice. Individual flies were then placed into 5 mm diameter glass capillary tubes with an agar plug at one end consisting of 1% agarose, 10% sucrose and 3 mM drug (where appropriate), and then plugged at the other end with cotton. Tubes were then placed into Trikinetics (Waltham, MA) activity monitor arrays, which were subsequently placed into a humidified incubator at 25°C with a 12 h light-dark cycle. Infrared beam breaks, as a measure of activity, were monitored with the Trikinetics Drosophila Activity Monitor System (DAMS). Sixteen males were used in each experiment for each treatment and monitored for seven days. Only activity data for days 3 and greater were used for analysis, omitting the first two days to allow for acclimation to the environment and to build up steady state drug levels.

The initial cell characteristics, as shown in Figure 5, were very promising. However, during the operation of the stack elevated degradation was recorded (see Figure 6). Over the course of galvanostatic operation (43 h), cell 1 lost 31 mV or 4.15% of the initial value, while cell 2 degraded by 61 mV (8.31%). Although the rate of performance loss in Figure 6 decreased considerably with increasing time at 0.5 A/cm2, we decided to cool down the stack and investigate the cells’ microstructure. Representative cross-sections are shown in Figure 7.

The community members in both Bura irrigation scheme and Ijara demonstrated good knowledge on malaria—its causes, symptoms, treatment and prevention by using bed nets. Insecticide treated nets (ITNs) are the most practical method of mosquito control that are used to protect at-risk individuals from mosquito bites and hence malaria infections . Through interviews, the community members in Bura irrigation scheme revealed a very high ownership and usage of mosquito nets regardless of whether it is treated or not. The use of untreated mosquito nets has been found to have some protective measures against mosquito bites while ITNs increases the mortality of vectors in addition to reducing vector-host contact, and therefore reducing the transmission of malaria .

As one perceived advantage of the study medication was the fact that methylphenidate was supplied in an extended-release formulation, six of seven parents and three of seven children and adolescents incorporated this expected advantage into their reasoning. The hope that the medication would be more effective because of the element of constant release was indicated as one reason influencing their decision. Furthermore, the fact that the new medication was easier to handle, in that it had to be taken only once a day and not twice or three times daily as was the case with the licensed preparations for ADHD, was seen as an advantage and a reason for participation. Six of seven parents, as well as 3 of the 7 children and adolescents asked to use a long-acting methylphenidate preparation, recognized that the once-a-day dosing decreased the risk of forgetting to take the medication and was a very important advantage as it made it possible for the children and adolescents not to have to take the medication in public (e.g. in school). Therefore, children and parents thought that once-a-day dosing removed the stigma associated with having to take the licensed preparation in public.

Another approach to inhibit bacterial growth is to disrupt the Quorum sensing (QS) system. This method has been widely considered in evaluations for the development of new therapies to deal with antimicrobial resistance. The QS systems involve bacteria communication that can control gene expression by signaling molecules or auto-inducers . In sensing the density of the cell quorum, the latter will cause the hardening of molecules in the environment and help activate the appropriate receptors on the cell surface or cytoplasm. Consequently, the transcription of the QS gene will be active . One of the genes allows for suppressing virulence and pathogenicity factors which can be encoded by the fsr locus of Enterococcus faecalis bacteria . Among the important fsrABCD genes, the fsrD gene is responsible for gelatinase biosynthesis-activating pheromone (GBAP) expresion. The active signal will be transmitted by other fsr genes, and the fsr control system will control the expression of protease gelatinase (GelE) and serine protease (SprE) . By blocking one of the QS stages such as GBAP inhibition, the cell–cell communication in bacteria will be ruined and the bacteria will die automatically . The other approach is to interfere with communication between bacterial cells and a QS system, facilitated by using computational and docking methods. Virtual filtering can help find the most appropriate set of compounds that show bioactivity from natural resources in an effective manner .

However, this finding was lower than studies done in Nigeria 60% , Ghana 79% , rural Chitwan (Nepal) 55% and in Ethiopia, such as Bahir Dar town 78.8% and Debre Markos Town 80.14% . The possible justifications for this might be due to; better access of health facility with improved health infrastructure, quality health services, having better educational status, better media exposure to access health information, easy access of transportation which enforces pregnant mothers to give birth at health facilities.

Frailty is particularly common in HF: in a meta-analysis, a 47.4% prevalence of frailty in patients with HF was estimated using multidimensional assessment tools.23 The prevalence of frailty in patients with HF is independent of age, suggesting a more complex interaction between the two syndromes and the progressive decline in physiological reserve. The mechanisms linking frailty to HF are multi-factorial, with inflammatory markers, impaired skeletal muscle function due to mitochondrial dysfunction, decreased capillary density, and adipose tissue infiltration potentially involved.3 Conversely, ageing, frailty, comorbidities, and immobility due to hospitalization, may all contribute to increase the severity and accelerate the progression of HF leading to increased risk of morbidity and mortality.24

A implementação da intervenção planejada teve diversos obstáculos à sua efetivação. No entanto, as intervenções mais consolidadas foram: o feedback da avaliação para os profissionais diretamente responsáveis pelo cuidado; as oficinas de qualificação do registro no prontuário eletrônico; a qualificação dos lembretes de registro adequado disparados para os profissionais de saúde; e a intervenção direta da equipe de melhoria nas equipes identificadas com maior fragilidade na assistência à sífilis.

This systematic review focused on nurses' knowledge, attitudes, and practice toward pharmacovigilance and ADR reporting and the associated barriers. Although nurses have a positive attitude toward PV and ADR reporting, their knowledge and practice in pharmacovigilance activities and ADR reporting were not at a suitable level of competence. In addition, lack of knowledge/training was the most significant barrier that influenced ADR reporting. Considering the critical role of nurses in PV activities and ADR reporting, sufficient attention should be paid to in-service training and degree-level education for nurses to ensure that this competence can be addressed. Also, facilitating access to the ADR reporting form, applying online submission of ADR reports, simplifying the ADR reporting process, and implementing electronic reporting and providing motivation and feedback can increase ADR reporting performance. However, it is recommended that future studies applying qualitative and quantitative research designs should investigate how nurses can be more actively engaged in ADR reporting.

(4) Daily Activities and Function. In Table 2 and Figure 5, the questions regarding daily activities were assessed using the Faces scale where 0 indicated no hurt and 5 indicated hurts worst. All the extra-alveolar screws had scored more than 2 and affected leisure activities. The speech was highly affected in the palatal implant (score of 2.82) followed by the buccal shelf (score of 2.57) and infrazgyomatic crest (1.8). The pain scores for taking a big bite and eating hard food were maximum for the buccal shelf (2.17) and palatal mini-implant (3.86). Overall, the maximum difficulty with eating was due to the mini-implants placed at the IZC followed by palatal mini-implants (score of 2.17), and the buccal shelf score was 1.17. The scores for difficulty in laughing had the maximum discomfort in the buccal shelf (3.05) followed by at the IZC region 2.8 and a score of 2.57 for mini-implants in the palate. On assessing all the questionnaires pertaining to mini-implants, the interradicular mini-implants all had scores less than 2. This suggested that they did not cause any discomfort or pain that affected daily activities and functions.

Our results showed that exposure to PCB118 and/or PCB153 reduced the expression of Lipin 1 in the liver and, to a lesser extent, in adipose tissue. Studies of lipin 1–deficient mice and cells have shown that lipin 1 is required for adipocyte differentiation. Lipin 1–deficient cells and tissues failed to induce expression of two key transcription factors of adipocyte differentiation, PPARγ and C/EBPα. Instead, these cells expressed high levels of preadipocyte factor-1, an inhibitor of adipogenesis . A strong negative correlation between lipin 1 mRNA levels in adipose tissue and glucose levels, insulin levels, and insulin resistance has been described in mice and humans . In humans, adipose Lipin 1 gene expression was strongly associated with both basal and insulin-mediated subcutaneous adipocyte glucose transport and mRNA levels of Glut4 . Interestingly, we also observed a decrease in Glut4 expression in adipose tissue after exposure to PCB118 and/or PCB153. In addition, we showed a less pronounced downregulation of Glut4 expression in other tissues. The insulin-regulated glucose transporter Glut4 is mainly expressed in insulin-responsive tissues, i.e., white and brown adipose tissue and heart and skeletal muscles. Glut4 mediates glucose uptake in response to acute insulin stimulation . Insulin-regulated glucose uptake in skeletal muscle and adipose tissue is dependent on the redistribution of Glut4 from intracellular storage sites to the plasma membrane . Impaired insulin stimulation of glucose uptake in adipose tissue and skeletal muscle is one of the earliest defects detected in insulin-resistant states. Insulin-resistance in type 2 diabetes, obesity, and aging is associated with a marked reduction in the intracellular pool of Glut4 protein in adipose cells, which in turn impairs insulin stimulation of glucose transport .

Commonly reported regulated miRNAs: U937, THP-1, HL-60 differentiation. Results of five studies of PMA-induced U937, THP-1, or HL-60 monocyte differentiation models were compared: Wang et al. , Coley et al. , Forrest et al. , and Chen et al. , and Kasashima et al. (combined). Only miR-17 was reported to be downregulated by more than one group, although all but Coley et al. reported downregulated miRNAs. Upregulated miRNAs were reported by J. Wang et al. (>30), Coley et al. (>60), Forrest et al. (>20), and the Chen and Kasashima studies (>10 combined). The 15 miRNAs presented here were found to be upregulated in at least two of the four study groups; miRs-146b, -221, and -222 (boxed) were common to all.

La Estrategia para el acceso universal a la salud y la cobertura universal de salud (Salud Universal) de la OPS de 2014 representa una referencia indispensable para considerar los retos más importantes de los sistemas de salud. En esta Estrategia la segmentación y la fragmentación de los programas de salud se identifican como dos desafíos centrales, que “se perpetúan por la falta de capacidad regulatoria dentro de los sistemas de salud, al igual que por la verticalidad de algunos programas de salud pública y la falta de integración de los mismos a nivel de la prestación de los servicios” (17). En este contexto, la sostenibilidad y la integración de los programas prioritarios, y en particular del PAI, son temas de especial relevancia.

Vâscosuplimentarea este un tratament sigur, eficient și bine stabilit al osteoartritei și constă în injectarea unei soluţii pe bază de acid hialuronic (HA) în articulațiile afectate. Terapia comună de vâscosuplimentare este concentrată în principal pe tratarea simptomelor, cum ar fi reducerea durerii, dar nu tratează cauza. Cu toate acestea, un tratament optim de vâscosuplimentare ar trebui să întârzie degenerarea cartilajului și chiar să ajute la regenerarea structurii cartilajului. O varietate de modificări chimice aduse acidul hialuronic natural (HA) au fost efectuate pentru a oferi robustețe mecanică și chimică, proprietăți reologice îmbunătăţite şi biostabilitate crescută, păstrând biocompatibilitatea și biodegradabilitatea polimerului nativ.

La prévalence globale de la PPCB en RCA est de 12,5%. Cette prévalence est supérieure à celle de la campagne sérologique de 2016 qui était de 7,7% , cependant sans différence significative, et cela montre que la PPCB est bien enzootique en RCA. Par ailleurs, nous n'avons pas observé de différence significative entre les régions. Les mouvements désorganisés de bétail, le regroupement des éleveurs en certaines zones et l'absence d'application des dispositions sanitaires relatives à la transhumance, pendant la période de la crise, pourraient expliquer ces résultats. Il n'y a pas eu non plus de différence significative de prévalence observée entre les femelles et les mâles, ce qui est en accord avec ce qui est connu de la PPCB et de ses facteurs de risque.

肺癌根治术后患者并发PTE更容易表现为高危PTE，因为行肺癌根治术的患者至少缺少一叶肺甚至一侧肺的血管床，累及同样肺血管的PTE对肺癌术后患者的影响更大。对于急性高危PTE的治疗方法，目前指南普遍建议溶栓或肺动脉血栓摘除术联合抗凝治疗。溶栓治疗的主要风险是并发致命性出血，特别是近期接受过重大手术治疗的PTE患者。手术取栓可以作为在溶栓治疗失败或溶栓绝对禁忌证患者的最终选择，但同样面临着高死亡率，约43%-84%。因此致命性高危PTE，缺少安全有效的治疗办法，溶栓治疗仍是其首选的治疗办法。在病例一的治疗方案中，我们在介入治疗前后均使用静脉溶栓治疗，虽然PTE的治疗效果显著，但患者很快出现了手术部位的活动性出血。有研究报道PTE行静脉溶栓治疗后发生出血的概率约20%，虽然没有关于胸部手术术后早期出现PTE行静脉溶栓治疗出血风险的研究，但我们相信这只会将更高。本例病人经过停用肝素、成份输血、纠正低血小板等治疗后出血停止且未出现PTE加重，最终转危为安。因此如何能降低溶栓治疗的出血并发症是这类病人治疗成功的关键，在没有革命性药物出现之前我们能改进的只有用药途径和剂量。在病例二的治疗过程中我们吸取教训，没有静脉应用溶栓药，仅在介入治疗过程中于靶血管内给药，在纠正休克、低血压状态后及时停用溶栓剂，改用肝素抗凝治疗，降低了患者的出血风险。

The difficulty in measuring reach was equally highlighted. During the intervention period, there was an increase in the national GBV calls received via the 116 call center helpline. While improvements may have been recorded, they may not be attributable to this multichannel messaging intervention campaign alone due to multiple projects implemented at the peak of the pandemic in Sierra Leone. Other implementing organizations had competing interventions to address similar project objectives.

Neste estudo, as causas mal definidas foram seguidas por “sequelas da hanseníase”, também indicando falhas operacionais no diagnóstico, tratamento e seguimento (7-9). Estudos realizados no Brasil e em estados endêmicos indicam percentuais de óbitos por sequelas de 5 a 11%, mais evidentes nas causas associadas (7, 8). Esse aspecto pode indicar falhas no alcance da atenção integral do Sistema Único de Saúde (SUS), especialmente após a alta da poliquimioterapia (12, 27), devido às restrições de acesso à rede de atenção básica e especializada. Isso pode gerar progressão de lesões associadas à hanseníase, eventualmente levando ao óbito (4, 6-8, 27). Um exemplo é o reconhecimento de sepse como principal causa de óbito associada à hanseníase de 1999 a 2007 (6, 7). O contexto de diagnóstico tardio de casos novos da doença verificado nessas regiões amplia o risco de desenvolvimento de síndromes clínicas ainda mais graves (2-4, 6).

The Illumina HiSeq 2500 platform was used to sequence the total DNA of the five studied specimens. After sequencing, the raw data was initially screened to remove low-quality regions affecting the data quality and subsequent analysis needed to obtain the expected clean data. The cpDNA genome was assembled by mapping onto the public complete chloroplast genome of P. persica cv. Lovell (GenBank accession HQ336405) , and the genome assembly and alignment analyses were performed using Geneious R10 program (http://www.geneious.com; Biomatters Ltd., Auckland, New Zealand).

Es gibt noch weitere sehr gut recherchierte und verständlich gestaltete Formate, die für die Menschen mit seltenen Erkrankungen viel bewirken. Beispielhaft sei hier die Sendung „Abenteuer Diagnose“ vom NDR genannt, aber auch die Rubriken „Die Diagnose“, „Der rätselhafte Patient“ oder „Seltene Erkrankungen“ der Magazine Stern, Der Spiegel oder Focus-Online. Allen ist gemein, dass sie sehr gut recherchiert sind, von erfahrenen, engagierten Medizinjournalistinnen und -journalisten gestaltet werden und auch komplexe Themen aus dem Bereich der „seltenen Erkrankungen“ verständlich vermitteln können. Dies kann zu einer Sensibilisierung und einem besseren Verständnis dieser Erkrankungen in der Bevölkerung führen, aber auch bei Ärztinnen und Ärzten, wie es sich am Zentrum für unerkannte und seltene Erkrankungen in Marburg schon gezeigt hat.

Although the average range of lipid droplets in other cells is 0.1 to 10 μm, in adipocytes they can accumulate up to 100 μm . Due to the proximity, breast cancer cells use lipids from adipocytes as a source of energy . Adipocytes can mobilize their stored lipids for breast cancer cell metabolic requirements through neutral lipolysis and autophagy. With the help of the catabolic enzyme adipocyte triglyceride lipase (ATGL), hormone sensitive lipase (HSL), monoacylglycerol lipase (MAGL), triglycerides, or triacylglycerol (TAG) are hydrolyzed into fatty acids (Figure 2) . ATGL converts triglycerides to diacylglycerol. Then, in the presence of HSL, diacylglycerol converts into monoacyl glycerol . In the final step, monoacylglycerol breaks down to a free FA and glycerol via the MAGL enzyme-mediated hydrolysis process . Thus, in obesity, there is an increased availability of circulating free fatty acid for breast cancer cells to offset their continuous metabolic needs. One in vitro study reported that the coculture of breast cancer cells and/or conditioned medium treatment from those cells on mouse 3T3-L1 adipocytes induces lipolysis from their triglyceride stores and increases the release of fatty acids . Released fatty acids are then taken up by the transmembrane channel protein CD36 found to be overexpressed in metastatic cancer cells . CD36, also known as fatty acid translocase (FAT), is from a solute carrier protein family that can bind to free fatty acids and facilitate their efficient movement across the plasma membrane . Further, evidence has also shown that fatty acid-binding protein 4 (FABP-4) is also found to be increased in breast cancer cells and is responsible for the intracellular trafficking of fatty acids .

Study outline of kinase inhibitor screening. Three BRAF mutated melanoma cell lines, A375, IGR37 and 501Mel (each one in its parental (P), Vemurafenib (XP)- and Dabrafenib (GP)-resistant form) were treated with 2 concentrations (1 and 10 μM) of 274 different kinase inhibitors. 40 promising candidates were further characterized in dose-response assays, which led to the identification of 14 compounds that were used in combination treatments where synergism was assessed. Short- and long-term effects of combinations with 8 successful drugs were analyzed: Danusertib (Aurora kinase, FGFR, Bcr-Abl, c-RET, Src inhibitor), MK-1775 (Wee1 inhibitor), AZD7762 (Chk inhibitor), AZD8330 (MEK inhibitor), CHIR-124 (Chk inhibitor), Volasertib (Plk inhibitor), PIK-75 (PI3K, DNA-PK inhibitor), TAE226 (FAK inhibitor). BRAFi: BRAF inhibitor, Vemurafenib or Dabrafenib

Iron is the most abundant transition metal in mammalian cells and is essential for the physiological function of multiple proteins . However, excess or non-protein-bound (labile) iron can be detrimental because it can initiate oxygen radical formation and promote ROS . Therefore, iron may cause oxidative damage to biological macromolecules and alter the intracellular redox environment, thereby affecting redox-sensitive cell signaling pathways and transcription factors , . Although the mechanisms underlying the cytotoxicity of iron in different organs are not fully delineated, many reports have pointed to the participation of iron-mediated peroxidation in numerous pathological states, including atherosclerosis , , cancer , , ischemia-reperfusion injury , IBD , and conditions of iron overload . Several laboratories –, –, – have shown the ability of iron to initiate strong lipid peroxidation, whereas ascorbic acid can amplify the oxidative potential of iron by promoting metal ion-induced lipid peroxidation. The data presented here clearly indicate that the FE/ASC system functioned as a producer of lipid peroxidation and, at the same time, altered the DNA integrity and the function of mitochondria. It is noteworthy that the iron dose used in the current study is comparable with normal iron concentration in the gut . The deteriorations resulting from the exposure of Caco-2/15 cells to FE/ASC are probably attributable to oxidative stress, because the addition of the BHT antioxidant simultaneously prevented the occurrence of lipid peroxidation and improved the cellular processes of mitochondrial integrity and functions. BHT was selected as an antioxidant because it represents a powerful agent inhibiting iron-mediated oxidative stress and does not have any toxic effects on Caco-2/15 cell culture .

Pi04089 interacts with a predicted K-homology RNA binding protein, KRBP1, which localises to nuclear speckles (Figure 1). Co-expression of KRBP1 with Pi04089 indicates that they interact at these speckles, and that the effector increases the abundance of KRBP1. Remarkably, overexpression of KRBP1 enhances P. infestans infection; a key criterion in defining it as an S factor [54•]. Pi04314 interacts in yeast and in planta with three isoforms of protein phosphatase 1 catalytic (PP1c) subunits (Figure 1). The effector promotes re-localisation of the PP1c isoforms from the nucleolus into the nucleoplasm; something that also happens during infection by P. infestans. Pi04314 interaction is mediated by an R/KVxF motif, indicating that Pi04314 mimics PP1c regulatory subunits. Either VIGS of the PP1c isoforms, or overexpression of a phosphatase-dead mutant of PP1c, reduces P. infestans infection, indicating that PP1c is required for infection. Indeed, the effector does not inhibit PP1c phosphatase activity, but rather is predicted to form a holoenzyme with PP1c, potentially directing its activity to the dephosphorylation of substrates involved in plant defence [55••]. In addition to being defined as an S factor, PP1c can also be considered an ‘effector helper’; a host protein that is co-opted by the effector to help modify defence proteins [53, 57]. The RXLR effector Pi02860 interacts in the cytoplasm and at the host PM with a non-phototrophic hypocotyl 3/Root phototropism 2 (NPH3/RPT2)-Like protein, NRL1 (Figure 1), which is predicted to form a ubiquitin E3 ligase with Cullin 3 [56•]. Remarkably, over-expression of NRL1 suppresses INF1-triggered cell death and enhances P. infestans leaf colonisation, whereas silencing of NRL1 by VIGS accelerates INF1-triggered cell death and reduces pathogen colonisation. NRL1 is a negative regulator of immunity, and thus a further S factor targeted by a P. infestans RXLR effector [56•]. Given that plants have well-tuned endogenous mechanisms for negative regulation of immunity, it is not surprising that pathogens have evolved effectors to exploit this.

O SRAA é muito complexo e cada vez mais amplia os conhecimentos, pois novos dados são acrescentados na didática cascata bioquímica que se inicia com a renina e finaliza na aldosterona. A complexidade é tanta que o bloqueio único com os inibidores da enzima conversora da angiotensina ou dos bloqueadores AT1 da Ang II promovem benefícios clínicos fantásticos, entretanto o bloqueio duplo apresenta resultados pífios ou até maléficos ao paciente. De tal forma, conclusões óbvias baseadas em aspectos fisiopatológicos não se aplicam plenamente para o SRAA.

L’évolution postopératoire des KE est habituellement simple; toutefois, une méningite aseptique peut survenir et engendrer une hydrocéphalie communicante, dont la prévention passe par l'exérèse totale tant que possible, l’éviction de la dispersion du contenu du kyste en peropératoire, ainsi que l'irrigation du foyer opératoire par de l'hydrocortisone . Elle n'apparaît pas uniquement quand l'exérèse est incomplète, comme ce qui a été décrit dans la littérature , mais le seul passage, en cours d'intervention, du contenu du KE dans le LCS peut expliquer la survenue de la méningite chimique, même si l'exérèse totale comprend la capsule . Elle peut être traitée par des ponctions lombaires répétées et une corticothérapie . L'hydrocéphalie est habituellement spontanément régressive, nécessitant rarement la mise en place d'une dérivation.

The temperature-controlled synthesis reaction of SEDF was performed using a Thermomixer comfort (Eppendorf, VWR International, Milan, Italy). The fluorescence experiments were performed with fluorimeter FP-6500 (Jasco, Easton, Pennsylvania, USA) using an excitation and emission wavelength of λex = 350 nm and λem = 450 nm, respectively (emission bandwidth: 10 nm; excitation bandwidth: 5 nm; data pitch: 1 nm; scanning speed: 100 nm min−1; sensitivity: low) and microplate readers Fluoroskan Ascent (Thermo Fisher Scientific, Milan, Italy) by selecting as filter pairs λex = 390 nm and λem = 460 nm, corresponding to the excitation and emission wavelengths, respectively. The absorbance measurements were obtained using a SPECTROstar Nano UV-Visible Spectrophotometer (Ortenberg, Germany) in 1.0 cm quartz cells at 20 °C. The mass spectrometry measurements, acquired in the positive-ion mode, were performed with a MALDI-TOF/TOF Ultraflex III (Bruker Daltonics, Milan, Italy) (matrix-assisted laser desorption/ionization time-of-flight mass spectrometry) by mixing the samples in a 1:1 ratio with 20 ng μL−1 DHB (2,5-dihydroxy benzoic acid) as matrix dissolved in 70% of acetonitrile, 25% trifluoroacetic acid, and 5% ethanol. The mass spectra were acquired in the positive-ion mode.

Mutations in the single homoeologous DME genes on the “A” and “B” sub-genome of bread and durum wheat were crossed in combinations to obtain DME double mutants. All crosses were made reciprocally and in duplicates. The F1 and later F2 seeds were obtained for 3 and 4 different mutant combinations, respectively, in Kronos and Express backgrounds. The mutations for stacking were selected based on the type (substitution, splice site variation, or premature stop codon), locations in the DME active site, and effect on gluten accumulation in the wheat endosperm. The F2 grains obtained from the aforementioned crosses were propagated in 48 well-flats and checked for zygosity of double mutations by PCR followed by DNA sequencing.

The effects of temperature and moisture on carbon fiber reinforced PPS resistance welded lap shear joints was acceded by Rohart et al. . The authors reported 26% and 61% of lap shear strength reduction relative to room temperature by exposing the welded joints at 82 °C and 150 °C (60 °C above Tg), respectively. The moisture did not affect the lap shear strength, thanks to the low moisture uptake of TPC materials.

Bach1 is also involved in epigenetic mechanisms of cancer progression. In both colorectal cancer and melanoma, the B-Raf protooncogene variant BRAF (V600E) upregulates v-maf avian musculoaponeurotic fibrosarcoma oncogene homolog G (MAFG), which heterodimerizes with Bach1 and recruits both chromodomain helicase DNA-binding protein 8 (CHD8, a chromatin remodeling factor) and the DNA methyltransferase DNMT3B, leading to the hypermethylation and transcriptional silencing of tumor-suppressor genes [54, 55] (Figure 4). Bach1 also promotes temozolomide (TMZ) resistance in patients with glioblastoma by antagonizing the p53-mediated suppression of O6-methylguanine DNA methyltransferase (MGMT); once activated, MGMT counteracts the antitumor effect of TMZ by reversing the TMZ-induced methylation of guanine residues .

Our meta-analysis did not found any heterogeneity in each of the OR. To minimize the bias of our research, we did not use the option of language limitation on PubMed, Medline, or Web of Science, and all previous studies that met our criteria were included. The study must be published in peer-reviewed journals; second, we collected the nAMD data in our studies, excluding the data of dry AMD and other type of wet AMD, such as Retinal angiomatous proliferation; third, all studies which fulfill the inclusion criteria were conducted with subjects of Asian ancestry, 5 studies were conducted in Japan, 1 study was conducted in China, 1 study was conducted in Singapore, 1 study was conducted in Thailand. We didn’t find any evidence or study about CFH I62V and PCV with subjects of Caucasian, Africa and other populations based upon our search strategy. Chen et al also reported that the polymorphisms at CFH, LOC387715, HTRA1, and C2 were found to be significantly associated with PCV, which was similar to our conclusions. But in their research the number of included studies was 5, which were all included in our study.

The Cryptococcus gattii R265 strain used in this study was kindly provided by Wieland Meyer (The University of Sydney, Australia). Plasmid pDNORNAT, which contains the nourseothricin marker cassette, was previously constructed by our group (70). Plasmid pJAF15, which contains the hygromycin resistance marker cassette was a generous gift of Joseph Heitman (Duke University, Durham, NC, USA). The strains were maintained on YPD agar (2% dextrose, 2% peptone, 1% yeast extract, and 1.5% agar). YPD plates containing nourseothricin (100 µg/ml) were used to select C. gattii mannoprotein deletion transformants (krp1Δ), and YPD plates containing hygromycin (200 µg/ml) were used to select C. gattii mannoprotein reconstituted transformants (krp1Δ::KRP1).

The N/P ratio refers to the ratio between the positively charged nitrogen (N) units on the chitosan polymer and the negatively charged phosphate (P) groups on nucleic acid. The overall charge of the chitosan-nucleic acid complex is determined by the N/P ratio and it also influences the ability of chitosan to fully condense nucleic acid which, in turn, affects the complex diameter . An increase in N/P ratio means a greater amount of chitosan relative to pDNA which can enhance complex stability, lead to higher osmotic pressure in the endosomes thus enhancing pDNA release and subsequent transgene expression . However, an N/P ratio that is too high can lead to excessively stable complexes that result in very slow or even no release of pDNA. N/P ratios that are too low lead to the formation of neutral or negatively charged complexes which cannot bind to the cell membrane and also tend to aggregate due to lack of inter-particular forces . With siRNA delivery higher N/P ratios appear to induce more efficient gene silencing. In one study, N/P ratios of 50 and 150 were shown to enhance gene silencing in a human lung sarcoma cell line (H1299 cells) when compared to low N/P ratios of 2 and 10. The highest efficiency was seen at N/P 150 with 80% gene knockdown achieved. This result was due to the increased stability of these complexes at higher N/P ratios and the increased charge also facilitated enhanced cellular uptake . This shows that the optimal N/P ratio is one that balances nucleic acid protection and stability with good release kinetics.

La butée coracoïdienne préglénoïdienne représente la méthode thérapeutique de choix dans le traitement des instabilités antérieures chroniques de l’épaule. Le résultat de l’intervention reste bon malgré les complications qui peuvent survenir à type d’arthrose, de lyse ou de mobilité de la vis. De réalisation rapide et facile, la technique de Latarjet est efficace sur les facteurs physiopathologiques et devrait aboutir à d’excellents résultats surtout subjectifs sur la stabilité, mais expose à un risque d’arthrose au long cours.

In the remainder of this paper, the two models (with unstructured and structured covariance matrix) are introduced in Section 2, where in addition to this a model for obtaining the within‐study correlation from published Prentice's criteria is described. In Section 2.7, the use of software is briefly reported, which is then followed by the application of the methods to data specific to the example in RRMS which is presented together with the results in Section 3. Simulation study investigating the robustness of the methods to the normality assumption as well as the performance of the methods is described in Section 4. Extensions of the two approaches to the multivariate case are developed in Section 5. The paper concludes with a discussion of methods in Section 6.
