Astrocyte-biased cells were successfully enriched from hNSPC cultures by DEP sorting, making this the first study to use electrophysiological properties for label-free enrichment of human astrocyte-biased cells. Enriched astrocyte-biased human cells enable future experiments to determine the specific properties of these important cells and test their therapeutic efficacy in animal models of neurological diseases. PURPOSE There has been an increased interest in simple measures of physical function and muscle strength that can be used in all clinical settings to assess individuals with chronic obstructive pulmonary disease (COPD) and predict their prognosis. The main objective was to examine the prognostic value of simple measures of physical function and muscle strength in relation to exacerbation, hospitalization and mortality in individuals with COPD. METHODS Medline, EMBASE, Cochrane and Web of Science were searched. We included prospective observational studies that examined the prognostic value of simple performed-based tests or self-reported measures of physical function or muscle strength in relation to exacerbation, hospitalization and mortality in individuals with COPD. RESULTS Seven articles met the inclusion criteria. The most commonly used tests were the handgrip strength (HGS) (n = 4) and 1-min sit-to-stand (STS) (n = 2). There were considerable variations in terms of characteristics of patients included, setting of recruitment, type of tests used, duration of follow-up and outcome measures of interest. The majority of the studies were classified as having "fair" or "poor" methodological quality. CONCLUSIONS There is a limited number of studies examining the prognostic value of simple measures of physical function and muscle strength in relation to exacerbations, hospitalizations and mortality in individuals with COPD. To date, the HGS and 1-min STS tests are the most studied tests and seem to be suitable for prognosis purposes in individuals with COPD. However, more studies with better methodological quality are needed to confirm these findings. BACKGROUND Viral respiratory infections (VRI) in people living with Cystic fibrosis (CF) is less well understood than respiratory bacterial infections, particularly adults with CF and few studies have compared children with adults. This study evaluated the frequency of respiratory viruses in patients with cystic fibrosis (CF) in Western Australia (WA). We determined the VRI in CF and compared them with non-CF patients. Further, we compared CF patients that were hospitalised with those that were not. PATIENTS/METHODS Nucleic acid from sputum of 157 CF and 348 non-CF patients was analysed for influenzavirus A (Flu A) and B, (Flu B), respiratory syncytial virus (RSV), human metapneumovirus (hMPV), human rhinovirus (RV), and parainfluenza viruses (PIV 1-3) by RT-PCR, during the 2016 winter respiratory season. RESULTS No significant difference in the frequency of respiratory virus detection between CF and non-CF patients was found. RV was the most frequently detected virus in CF patients, and in hospitalised CF. RSV and hMPV were found less frequently in CF patients and RSV was not found in any hospitalised CF patient. A trend for fewer influenzavirus detections in adult CF patients was observed, however the trend was opposite for paediatric patients. RV and Flu A were the most common viruses detected in hospitalised CF patients. CONCLUSION There was no significant difference in VRI between CF and non-CF patients. RV and influenza A were most commonly found in hospitalised CF patients, suggesting that infection with these viruses may contribute to hospitalisation for CF respiratory exacerbations. BACKGROUND Limited data exist on the development of tuberculosis (TB) in cancer patients receiving immune checkpoint inhibitors (ICIs). METHOD s We evaluated the development of TB in 1144 solid-cancer patients who started ICIs (pembrolizumab, nivolumab, or atezolizumab) between July 2014 and December 2018. RESULTS A total of 1144 cancer patients were treated with ICIs. The median age of the patients at the start of ICI treatment was 62 years (interquartile range [IQR]; 53-69 years). Lung cancer (n = 796, 69.6%) was the most common cancer followed by melanoma (n = 115, 10.1%), and lymphoma (n = 85, 7.4%). Pembrolizumab (n = 612, 53.5%) was the most common treatment, followed by nivolumab (n = 474, 41.4%) and atezolizumab (n = 58, 5.1%). The median treatment duration with ICIs was 42 days (IQR; 18-154 days), and the median follow-up duration after initiating ICIs was 187 days (IQR; 70-342 days). Overall, three patients developed TB, two of whom received nivolumab and one who received pembrolizumab. CONCLUSIONS Our data showed that TB can develop in cancer patients receiving ICIs. However, due to the small number of study population, it is insufficient to draw accurate conclusions about the role of ICIs in the development of TB. Moreover, it is unclear whether the incidence of TB would be comparable with the incidence of TB in elderly cancer patients. Further studies are needed to evaluate whether diagnosis and treatment of latent TB infections before starting ICIs could be helpful in preventing the development of TB in these patients. OBJECTIVE The aim of the study was to investigate the mechanism and effect of FBXL10 in myocardial ischemia reperfusion injury in vivo and in vitro. METHODS The myocardial ischemia reperfusion (I/R) model was established by 30 min of coronary occlusion followed by 2 h of reperfusion in rats. Western blot and TUNEL assay were used to measure the apoptosis during I/R. selleck inhibitor The expression levels of endoplasmic reticulum related proteins in myocardial tissues and H9c2 cells were detected by immunohistochemistry staining and immunofluorescence staining. Flow cytometry and CCK-8 were used to detect the apoptosis and viability of H9c2 cells. RESULTS The results revealed that FBXL10 significantly reduced myocardial infarction, improved the pathological morphology of myocardium, markedly reduced inflammatory response in the myocardial ischemia reperfusion rats. Moreover the expressions of endoplasmic reticulum stress key proteins were caused by I/R were suppressed significantly by FBXL10 treatment, including CHOP, GRP78, ATF4 and p-PERK.
