Long noncoding RNAs (lncRNAs) can participate in various biological behaviors, including regulating cell differentiation, proliferation and apoptosis. The investigators have previously confirmed that highly conserved lncRNA NR_045363 controls cardiomyocyte (CM) proliferation and cardiac repair. The present study investigates the effects of NR_045363 on CM apoptosis. Seven-day-old mice were subjected to permanent left anterior descending coronary artery ligation (LAD), and the NR_045363 expression was analyzed by quantitative real-time polymerase chain reaction (qRT-PCR). The expression of NR_045363 in the MI group significantly exceeded the Sham group during the first week after the operation. The NR_045363 expression was knocked down in primary cultured CMs using a NR_045363-targeting LncRNA Smart silencer, and the apoptosis of CMs was analyzed by Terminal-deoxynucleoitidyl Transferase Mediated Nick End Labeling (TUNEL) and Annexin-V/PI double staining. These present results indicate that the NR_045363 knockdown significantly promoted the apoptosis of CMs. In order to investigate the underlying mechanism, RNA-sequencing (RNA-seq) was performed, and ingenuity pathway analysis (IPA) was used to analyze the RNA-seq results. The RNA-seq data revealed that a total of 2,291 genes were upregulated or downregulated in NR_045363 knockdown CMs, and the IPA analysis indicated that p53 was the upstream regulator. In vivo, the NR_045363 overexpression through the AAV9 system improved the heart function after MI in 7-day-old mice and inhibited the CM apoptosis. These data suggests that NR_045363 is involved in CM apoptosis, and that NR_045363 overexpression exerts positive effects on cardiac repair by alleviating CM apoptosis through the activation of the p53 pathway.

Concurrently, concerns about potential shortages of healthcare professionals and health supplies to address these issues have focused attention on how these resources are ultimately allocated and used. Some strategies, for example, misguidedly use age as an arbitrary criterion, which disfavors older adults in resource allocation decisions. This is a companion manuscript to the American Geriatrics Society (AGS) position statement, "Resource Allocation Strategies and Age-Related Considerations in the COVID-19 Era and Beyond." It is intended to inform stakeholders including hospitals, health systems, and policymakers about ethical considerations that should be considered when developing strategies for allocation of scarce resources during an emergency involving older adults. This review presents the legal and ethical background for the position statement and discusses the following issues that informed the development of the AGS positions (1) age as a determining factor; (2) age as a tiebreaker; (3) criteria with a differential impact on older adults; (4) individual choices and advance directives; (5) racial/ethnic disparities and resource allocation; and (6) scoring systems and their impact on older adults. It also considers the role of advance directives as expressions of individual preferences in pandemics. This article is protected by copyright.

In this study, a pharmacokinetic model of ethanamizuril was established on the basis of the blood concentration of 81 experimental animals. The final model showed that ethanamizuril was distributed as a two-compartment model with first-order absorption after oral administration in chickens. Its clearance rate and volumn of central compartment distribution (Vc ) were affected by age and body weight, and volumn of central compartment distribution (Vc ) and volume of peripheral compartment distribution(Vp ) were influenced by weight and infection. External verification revealed that the model had good prediction accuracy and stability. © 2020 John Wiley & Sons Ltd.Multiple sclerosis (MS) is an autoimmune disease of the central nervous system that is caused by the interaction of genetic and environmental factors. Current studies have shown that Fc-receptor like-3 (FCRL3) is closely related to MS, but the specific role of FCRL3 in MS has not yet been clarified. This study further found that FCRL3 and interleukin 10 (IL-10) expression was downregulated in MS patients, but the expression of these proteins was higher in the remission phase than that in the acute phase. The C allele of rs7528684 was associated with MS, and the CC genotype could lead to the upregulation of FCRL3 expression and the increase in IL-10 secretion. Further in vitro experiments with B cells found that lipopolysaccharide (LPS) promoted FCRL3 expression in a dose- and time-dependent manner, thereby promoting IL-10 secretion. LPS regulated Src homology region 2 domain-containing phosphatase-1 (SHP-1) expression and p38 mitogen-activated protein kinase (MAPK) pathway activation through FCRL3, and FCRL3 upregulated the SHP-1 expression and p38 phosphorylation levels. When SHP-1 small interfering RNA or a p38 pathway inhibitor was added, the effect of FCRL3 on IL-10 secretion was significantly inhibited. SGCCBP30 In addition, FCRL3 inhibited the secretion of inflammatory factors (tumor necrosis factor-α, IL-1β, IL-6, and IL-8); after inhibiting the expression of IL-10, the abovementioned effects of FCRL3 were blocked. These results suggest that FCRL3 can activate the SHP-1 and p38 MAPK pathways and then promote the secretion of IL-10 in B cells, thus inhibiting the secretion of inflammatory factors. Therefore, FCRL3 may play an immunoprotective role in MS, and it will be an effective target for the diagnosis and treatment of MS. © 2020 International Federation for Cell Biology.Besides their widespread use in coordination chemistry, 2,2'-bipyridines are known for their ability to undergo cis-trans conformational changes in response to metal ions and acids, which has been primarily investigated at the molecular level. However, the exploitation of such conformational switching in self-assembly has remained unexplored. Herein, we have pioneered the use of 2,2'-bipyridines as acid-responsive conformational switches to tune supramolecular polymerization processes. To achieve this goal, we have designed a bipyridine-based linear bolaamphiphile 1 that forms ordered supramolecular polymers in aqueous media via cooperative aromatic and hydrophobic interactions. Interestingly, addition of acid (TFA) induces the monoprotonation of the 2,2'-bipyridine moiety, leading to a switch in the molecular conformation from a linear ( trans ) to a V-shaped ( cis ) state. This increase in molecular distortion along with electrostatic repulsions of the positively charged bipyridine-H + units attenuate the aggregation tendency and induces a transformation from long fibers to shorter thinner fibers. Our findings may contribute to opening up new directions in molecular switches and stimuli-responsive supramolecular materials. © 2020 WILEY-VCH Verlag GmbH & Co.

OBJECTIVES This study explores the psychometric properties of the Portuguese USCD Performance-based Skill Assessment 2 (UPSA-2-PT) in a mixed sample of Portuguese participants. METHOD A sample of 110 participants, 37 patients diagnosed with schizophrenia, 27 first-degree relatives of patients and 46 controls were administered the UPSA-2-PT and self-report questionnaires. The UPSA-2-PT reliability was assessed through inter-rater reliability and internal consistency, convergent validity with community integration and a receiver operating curve analysis was conducted to establish scores' sensitivity and specificity. Youden's Index was used to determine an optimal UPSA-2-PT cutoff score. RESULTS Findings show an excellent inter-rater reliability, good internal consistency and construct validity, consistent with previous studies in Western countries. The UPSA-2-PT also showed a good discriminant ability between patients and controls, and an overall percentage of correct classification of 86.7% based on the 81.59 cutoff. DISCUSSION Findings are congruous with previous versions, strengthening the body of evidence supporting the construct validity and providing a useful tool for research and clinical purposes to practitioners. © 2020 John Wiley & Sons Ltd.Phaeohyphomycosis is a dermatomycosis caused by black yeasts1,2 . Exophiala jeanselmei has been thought to be a main pathogenic fungus3 . Recently, however, molecular analysis of the internal transcribed spacer (ITS) region of ribosomal ribonucleic acid (rRNA) revealed that phaeohyphomycosis due to E. jeanselmei was rather rare3,4 . Therefore, accumulation of cases is needed to reestablish the disease concept. Here, we present a case of phaeohyphomycosis due to E. jeanselmei mimicking an epidermal cyst in a healthy farmer.

Regardless of the choice of the system, designing a plant for producing advanced therapies requires a clear understanding of the final objective (the product), taking into account all the regulatory, environment, process, risk assessment, asepsis and validation aspects involved until its implementation. Good Manufacturing Practice (GMP) compliant procedures are a prerequisite for cell production in clinical application, and clean rooms are zones for producing cell therapies. Clean rooms for clinical application require high running and maintenance costs and need trained operators and strict procedures to prepare the rooms and the people involved in the processes. While today production mainly occurs in open systems (clean rooms), there is evidence of processes in closed systems (isolators). The isolator is a Grade A aseptic closed syst reserved.

Coronaviruses enter cells via fusion of the viral envelope with the plasma membrane and/or via fusion of the viral envelope with endosomal membranes after virion endocytosis. The spike (S) glycoprotein is a major determinant of virus infectivity. Herein, we show that the transient expression of the SARS CoV-2 S glycoprotein in Vero cells caused extensive cell fusion (formation of syncytia) in comparison to limited cell fusion caused by the SARS S glycoprotein. Both S glycoproteins were detected intracellularly and on transfected Vero cell surfaces. These results are in agreement with published pathology observations of extensive syncytia formation in lung tissues of patients with COVID-19. These results suggest that SARS CoV-2 is able to spread from cell-to-cell much more efficiently than SARS effectively avoiding extracellular neutralizing antibodies. A systematic screening of several drugs including cardiac glycosides and kinase inhibitors and inhibitors of human immunodeficiency virus (HIV) entry revealed that only the FDA-approved HIV protease inhibitor, nelfinavir mesylate (Viracept) drastically inhibited S-n- and S-o-mediated cell fusion with complete inhibition at a 10-μM concentration.
