Survival and brain function are assessed at discharge or 30 days (or both if possible) and between 6 and 12 months after arrest. Cognitive function, physical function, and basic daily life skills are assessed between 6 and 12 months after cardiac arrest. Because many children have prearrest comorbidities, the P-COSCA also includes documentation of baseline (ie, prearrest) brain function and calculation of changes after cardiac arrest. Supplementary outcomes of survival, brain function, cognitive function, physical function, and basic daily life skills are assessed at 3 months and beyond 1 year after cardiac arrest if resources are available.Hematopoietic stem cells (HSCs) are characterized by their ability to produce all cells of the blood and immune system and have been used for transplantation for decades. Although the regenerative potential of HSCs is high, their self-renewal potential is limited. HSC functions are inversely correlated with their divisional history. Recent advances in our understanding of the regulation of HSCs through cell division suggest that HSCs may never replicate into identical self, but rather replicate into progeny that gradually lose functionality at each round of division. HSC division is accompanied by major transcriptional and metabolic changes. In this perspective, the possibility that mitochondrial metabolism confers HSC division memory and programs HSCs for extinction is discussed.Protein tyrosine phosphatase receptor σ (PTPσ) is highly expressed by murine and human hematopoietic stem cells (HSCs) and negatively regulates HSC self-renewal and regeneration. Previous studies of the nervous system suggest that heparan sulfate proteoglycans can inactivate PTPσ by clustering PTPσ receptors on neurons, but this finding has yet to be visually verified with adequate resolution. Here, we sought to visualize and quantify how heparan sulfate proteoglycans regulate the organization and activation of PTPσ in hematopoietic stem/progenitor cells (HSPCs). Our study illustrates that syndecan-2 promotes PTPσ clustering, which sustains phospho-tyrosine and phospho-ezrin levels in association with augmentation of hematopoietic colony formation. Strategies that promote clustering of PTPσ on HSPCs may serve to powerfully augment hematopoietic function.'Winner' and 'loser' effects have been demonstrated in a broad range of species, but such investigations are often limited to the effects of prior contest outcomes on future agonistic interactions. Much less is known about the impacts of winning or losing contests on other aspects of individual behavior, like courtship interactions and sheltering behavior. In this investigation, I examined the effect of prior contest outcomes on sheltering behavior in the crayfish Faxonius virilis. I predicted that winners of contests would spend less time inside shelters and more time exploring, while losers of contests would spend more time inside shelters and less time exploring. I compared individual sheltering behavior before and after staged dyadic encounters between competitively mismatched individuals. This experiment revealed strong effects on the behavior of contest losers, which showed significant increases in the amount of time spent inside the shelter immediately after the contest. However, there was no significant change in the sheltering behavior of contest winners. These results reinforce the idea that contest outcomes can affect individual behaviors other than agonistic behavior, and suggest that losing a contest may motivate individual crayfish to engage in less-risky behavior, at least for a brief period after the contest.
  Pool testing is one of the strategy to expedite testing capacities while simultaneously conserving various diagnostic kits, reagents and consumables and time. In the present study, we investigated potential role of combined specimen collection technique for the diagnosis of SARS-CoV-2 virus infection where five nasopharyngeal swabs were collected from different individuals and pooled together in a single viral transport medium (VTM).
 
  This pilot study was conducted on different cohorts of Delhi state. Two nasopharyngeal swabs were collected from each enrolled individual. One swab was put into VTM vial to be further used for individual swab testing (ID). The other swab was put into a fresh VTM for pool swab collection. Each pool comprised five swabs collected from five different patients in one VTM vial. Both IDs and pools were tested in parallel for the detection of SARS-CoV-2 using real time PCR.
 
  A total of 46 pools were collected from 230 enrolled individuals.Among 230 ID tested, 60 were found to be positive for both E and RdRp gene. Among 46 pools, 25 pools included all negatives samples and remaining 21 pools included one or more positives. Comparing ID with pool results, overall concordance was seen in 42 pools (91.3%). Four pools showed false positive results as all included samples on ID testing were found to be negative. Considering ID results as reference, swab pool showed 100% sensitivity, 84% specificity, 84% positive predictive value and 100% negative predictive value.
 
  The pooling of swab strategy could be beneficial only among asymptomatic in low prevalence areas.

  Hepatitis B virus (HBV) is one of the leading causes of morbidity and mortality across the globe. The pathogenesis, clinical outcomes, disease progression and response to antiviral treatment of HBV depend on infecting genotypes and mutations across HBV genome. There is a lack of such information from central India. The present study was planned to identify genotype/subgenotype and epidemiologically important mutation in HBV circulating in the area.
 
  Samples positive for HBsAg by ELISA from 2012 to 2016 were included and analysed in this retrospective study. The amplification of partial S gene (n = 25) and full genome (n = 10) was carried out to determine the genotype/subgenotype and genome wide mutations of HBV.  https://www.selleckchem.com/products/bardoxolone.html  The sequencing data was analysed using bioinformatics tools.
 
  All 25 sequences belonged to genotype D; subgenotypes D1, D2, D3 and D5 with dominance of D1 were detected in the study subjects. Mutational profiling revealed the presence of nucleotide substitutions in promoter/regulatory/precore region associated with liver disease progressions.
