It can be challenging to maintain tissue integrity using established histology protocols. Here, we describe a protocol composed of Hartman's fixation, window technique, microwave-based tissue processing, optimized depigmentation, and antigen retrieval pretreatment. This is followed by the ViewRNA single-molecule fluorescence in situ hybridization and immunofluorescence techniques to optimize routine histological staining and molecular histology multiplexing assays. Our protocol is highly reproducible in any laboratory and may decrease animal usage and lab resource expenditure. For complete details on the use and execution of this protocol, please refer to Pang et al. (2021).We have recently demonstrated that the activity of hexokinase 2 is dependent on the intracellular potassium ion (K+) concentration ([K+]). To analyze the K+ dependency of the cell metabolism in cell populations, we used an extracellular flux analyzer to assess oxygen consumption and acidification rates as well-established measures of oxidative- and glycolytic metabolic activities. This protocol describes in detail how a potential K+ sensitivity of the cell metabolism can be elucidated by extracellular flux analysis. For complete details on the use and execution of this protocol, please refer to Bischof et al. (2021).Coronavirus disease 2019 (COVID-19) is threating global public health and has declared as a pandemic crisis around the world. An attempt was made to ascertain the effect of COVID-19 on practices in poultry farming (PPF), problem faced for poultry farming (PFPF) and poultry farmer's perception on COVID-19. A questionnaire based cross-sectional study was conducted among 397 poultry farmers during the period of October to December 2020 in selected area of Bangladesh. The PPF score at just prior and during of the COVID-19 was 7.11 ± 3.25 and 6.53 ± 3.12 having significant difference (p less then 0.01). But, the training on poultry farming can improve the PPF score at just prior (7.57 ± 3.20) and during (6.91 ± 3.13) of the COVID-19. Additionally, the mean PFPF score was found of 10.67 ± 6.15. In logistic regression analysis, the farmers of ≥18-29 years aged and had no training were 0.42 (95% CI0.20-0.88; p less then 0.01) and 0.58 (95% CI0.35-0.98; p less then 0.05) times respectively less likely to have satisfactory score on PPF. Similarly, the farmers of ≥18 to 29 and ≥ 40-49 years aged were 2.52 (95% CI1.36-4.69; p less then 0.01) and 2.08 (95% CI1.12-3.87; p less then 0.05) times respectively more likely to have considerable score on PFPF than the farmers of other age group. Interestingly, the internet users had 2.51 (95% CI0.95-6.57; p less then 0.05) times higher to have more satisfactory PPF score (≥60%). Moreover, the farmers of ≥18-29 years aged, masters level education and had training, significantly (p less then 0.01) thought the COVID-19 is more dangerous indicated by the higher median (median = 8). In conclusion, the PPF and PFPF score was significantly varied by demographical characteristics of farmers. Therefore, the farmers had the concept about COVID-19 and more than 75% of them believe that COVID-19 doesn't transmit from poultry.The purpose of the present study was to investigate the vesicant countermeasure effects of hydrocortisone (HC) and ebselen (EB-1), administered as monotherapy or as a combination treatment. The mouse ear vesicant model (MEVM) was utilized and test doses of HC (0.016, 0.023, 0.031, 0.047, 0.063, 0.125 or 0.250 mg/ear), EB-1 (0.125, 0.187, 0.250, 0.375 or 0.500 mg/ear) or the combination of HC + EB-1 were topically applied at 15 min, 4 h and 8 h after nitrogen mustard exposure. Ear punch biopsies were obtained 24 h after mechlorethamine (HN2) exposure. Compared to control ears, ear tissues exposed topically to HN2 (0.500 µmol/ear) presented with an increase in ear thickness, vesication, TUNEL fluorescence and expression of matrix metalloproteinase 9 (MMP-9) and inducible nitric oxide synthase (iNOS). In contrast, HN2 exposed ears treated topically with EB-1 showed a significant decrease in morphometric thickness and vesication vs. HN2 alone. Ear tissues exposed to HN2 and then treated with HC also demonstrated reductions in morphometric thickness and vesication. Combination treatment of HC + EB-1 was found to be the most effective at reducing HN2-induced ear edema and vesication. The combination also dramatically decreased HN2-mediated cutaneous expression of iNOS and MMP-9 and decreased HN2-induced TUNEL staining. Taken together, our study demonstrates that the combination of HC + EB-1 is an efficacious countermeasure to HN2.Antipsychotic drugs (APDs) are prescribed for the treatment of psychiatric illness. However, these drugs can also contribute to several developmental and behavioral disorders. Contemporary studies to evaluate the toxic effects of numerous atypical antipsychotics are reported to cause behavioral alteration at variable doses in mammals and nematodes. Risperidone, the second most prescribed drug in India, requires more exploration of its adverse effects on humans. Here, we explore effects on feeding behavior and locomotion patterns due to risperidone exposure in C. read more elegans model. The study targets to work out the toxic effects of risperidone exposure on feeding and locomotion behavior in addition to the expected pharmacological effects. N2 wild type strain was exposed in liquid culture assay for 2, 4, 6, 8, 10, and 12 hours with fixed 50 µM concentration. Feeding behavior was depleted due to inhibition in pharyngeal pumping varying from 11.05% - 45.67% in a time-dependent manner. Results of locomotion assay also show time-varying increase in reversals (4.9%-34.03%) and omega bends (26.23%-62.17%) with reduction in turn counts (29.07%- 42.2%) and peristaltic speed (31.38%-42.22%) amongst exposed groups as to control. The present work shows behavioral alterations due to risperidone exposure (50 µM) in C. elegans is in a time-dependent manner. The study concludes that risperidone exposure in C. elegans produces toxic effects with time, possibly caused by antagonizing other receptors apart from serotonin (5-H2T) and dopamine (D2) adding to its expected pharmacological effects.
Many individuals take long-term immunosuppressive medications. We evaluated whether these individuals have worse outcomes when hospitalised with COVID-19 compared with non-immunosuppressed individuals.

We conducted a retrospective cohort study using data from the National COVID Cohort Collaborative (N3C), the largest longitudinal electronic health record repository of patients in hospital with confirmed or suspected COVID-19 in the USA, between Jan 1, 2020, and June 11, 2021, within 42 health systems. We compared adults with immunosuppressive medications used before admission to adults without long-term immunosuppression. We considered immunosuppression overall, as well as by 15 classes of medication and three broad indications for immunosuppressive medicines. We used Fine and Gray's proportional subdistribution hazards models to estimate the hazard ratio (HR) for the risk of invasive mechanical ventilation, with the competing risk of death. We used Cox proportional hazards models to estimate HRs for in-hed risk of invasive mechanical ventilation. Although there was no statistically significant association between most drugs and in-hospital death, increases were found with rituximab for rheumatological disease (1·72, 1·10-2·69) and for cancer (2·57, 1·86-3·56). Results were generally consistent across subgroup analyses that considered race and ethnicity or sex, as well as across sensitivity analyses that varied exposure, covariate, and outcome definitions.

Among this cohort, with the exception of rituximab, there was no increased risk of mechanical ventilation or in-hospital death for the rheumatological, antineoplastic, or antimetabolite therapies examined.

The purpose of this study is to examine the effects of fatigue on muscular performance, oxygenation saturation, and cognition following acute hypoxic exposure at Normoxia, Moderate Hypoxia (MH), and Severe Hypoxia (SH).

Twelve males performed 3 sets of leg extensions to failure under Normoxia (FiO
21%), MH (Fi0
15.4%), and SH (Fi0
12.9%). Heart rate, peripheral oxygenation saturation, total saturation index, psychomotor vigilance testing reaction time, psychomotor vigilance error rate, maximum strength, and repetitions to failure were measured throughout each visit.

The primary findings indicated that MH and SH resulted in significant decreases in psychomotor vigilance test performance (MH 388.25-427.17ms, 0.41-0.33 error rate; SH 398.17-445.42ms reaction time, 0.25-1.00 error rate), absolute muscle tissue oxygen saturation (Abs-StO
) (MH67.22% compared to SH57.56%), but similar muscular strength, heart rate, and patterns of muscle tissue oxygen saturation responses (StO
%) during fatigue when cinfluencer to muscle oxygenation status than hypoxic conditions (FiO
15.4 and 12.9%).
Acute hypoxic exposure in the current study was not a sufficient stimuli to elicit hypoxic-related changes in HR, muscular strength (1-RM), or repetitions to failure. The SpO2 responses were hypoxic-level dependent with increasing levels of hypoxia resulting in greater and more sustained reductions in SpO2. The combined SpO2 and StO2 responses at MH and SH suggested a balance between the muscles metabolic demand remaining lower than the muscle oxygen diffusion capacity. During the SH condition, Abs-StO2 suggested greater metabolic stress than Normoxia and MH conditions during the fatiguing leg extensions. The patterns of responses for StO2% during the three sets of leg press to failure indicated that exercise is a more potent influencer to muscle oxygenation status than hypoxic conditions (FiO2 15.4 and 12.9%).The recent release of SARS-CoV-2 genomic data from several countries has provided clues into the potential antigenic drift of the coronavirus population. In particular, the genomic instability observed in the spike protein necessitates immediate action and further exploration in the context of viral-host interactions. By temporally tracking 527,988 SARS-CoV-2 genomes, we identified invariant and hypervariable regions within the spike protein. We evaluated combination of mutations from SARS-CoV-2 lineages and found that maximum number of lineage-defining mutations were present in the N-terminal domain (NTD). Based on mutant 3D-structural models of known Variants of Concern (VOCs), we found that structural properties such as accessibility, secondary structural type, and intra-protein interactions at local mutation sites are greatly altered. Further, we observed significant differences between intra-protein networks of wild-type and Delta mutant, with the latter showing dense intra-protein contacts. Extensive molecular dynamics simulations of D614G mutant spike structure with hACE2 further revealed dynamic features with 47.7% of mutations mapping on flexible regions of spike protein. Thus, we propose that significant changes within spike protein structure have occurred that may impact SARS-CoV-2 pathogenesis, and repositioning of vaccine candidates is required to contain the spread of COVID-19 pathogen.
