The Coronavirus (COVID-19) pandemic has presented a myriad of organizational and institutional challenges. The Uniformed Services University of the Health Sciences, like many other front line hospitals and clinics, encountered a myriad of challenges in fostering and sustaining the education of students enrolled at the nation's only military medical school. Critical to the function of any academic medical institution, but particularly one devoted to the training of future physicians for the Military Health System, was the ability to rapidly adapt, modify, and create new means of keeping medical students engaged in their core curricula and progressing toward full and timely attainment of established educational goals and objectives.

This article highlights some of the particular challenges faced by faculty and students during the first 6 months of the COVID-19 pandemic and describes how they were managed and/or mitigated.

Six key "lessons learned" were identified and summarized in this manuscript. These lessons may be applicable to other academic institutions both within and outside of the Military Health System.

Recognizing and embracing these key tenets of academic change management can accelerate the generation of a cohesive, organizational response to the next pandemic or public health crisis.

The present study used a combination of genetic and molecular approaches to explore the assembly of RNA polymerase III (Pol III) in yeast. We identified a regulatory link between Rbs1, a Pol III assembly factor, and Rpb10, a small subunit that is common to three RNA polymerases. Overexpression of Rbs1 increased the abundance of both RPB10 mRNA and the Rpb10 protein, which correlated with suppression of Pol III assembly defects. Rbs1 is a poly(A)mRNA-binding protein and mutational analysis identified R3H domain to be required for mRNA interactions and genetic enhancement of Pol III biogenesis. Rbs1 also binds to Upf1 protein, a key component in nonsense-mediated mRNA decay (NMD) and levels of RPB10 mRNA were increased in a upf1Δ strain. Genome-wide RNA binding by Rbs1 was characterized by UV cross-linking based approach. this website We demonstrated that Rbs1 directly binds to the 3' untranslated regions (3'UTRs) of many mRNAs including transcripts encoding Pol III subunits, Rpb10 and Rpc19. We propose that Rbs1 functions by opposing mRNA degradation, at least in part mediated by NMD pathway. Orthologues of Rbs1 protein are present in other eukaryotes, including humans, suggesting that this is a conserved regulatory mechanism.

In the United States, firearm suicide represents a major cause of preventable, premature death among veterans. The purpose of this systematic review was to characterize the body of literature on veteran firearm suicide and identify areas for future research, which may facilitate the development of firearm suicide interventions in Veterans Health Administration (VHA) and non-Veterans Health Administration clinical settings.

All randomized controlled trials, quasi-experimental, naturalistic, observational, and case study designs published between January 1, 1990 and February 21, 2019 were included in our review. Following title and abstract review, 65 papers were included in our full-text review and 37 studies were included in our analysis. We based our approach on a modification of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Studies were grouped into broad, nonmutually exclusive categories (1) heterogeneity of datasets and veteran status determination for inclusion, (d definitions that are critical to inform clinical practice and enhance public health measures to reduce firearm suicide among veterans.

This systematic review highlights an urgent need to produce higher quality evidence and new data with standard definitions that are critical to inform clinical practice and enhance public health measures to reduce firearm suicide among veterans.Whole-genome mapping technologies have been developed as a complementary tool to provide scaffolds for genome assembly and structural variation analysis (1,2). We recently introduced a novel DNA labeling strategy based on a CRISPR-Cas9 genome editing system, which can target any 20bp sequences. The labeling strategy is specifically useful in targeting repetitive sequences, and sequences not accessible to other labeling methods. In this report, we present customized mapping strategies that extend the applications of CRISPR-Cas9 DNA labeling. We first design a CRISPR-Cas9 labeling strategy to interrogate and differentiate the single allele differences in NGG protospacer adjacent motifs (PAM sequence). Combined with sequence motif labeling, we can pinpoint the single-base differences in highly conserved sequences. In the second strategy, we design mapping patterns across a genome by selecting sets of specific single-guide RNAs (sgRNAs) for labeling multiple loci of a genomic region or a whole genome. By developing and optimizing a single tube synthesis of multiple sgRNAs, we demonstrate the utility of CRISPR-Cas9 mapping with 162 sgRNAs targeting the 2Mb Haemophilus influenzae chromosome. These CRISPR-Cas9 mapping approaches could be particularly useful for applications in defining long-distance haplotypes and pinpointing the breakpoints in large structural variants in complex genomes and microbial mixtures.Osmotic adjustment is almost ubiquitous as a mechanism of response to drought in many forest species. Recognized as an important mechanism of increasing turgor under water stress, the metabolic basis for osmotic adjustment has been described in only a few species. We established an experiment with four species of the genus Quercus ranked according to drought tolerance and leaf habit from evergreen to broad-leaved deciduous. A cycle of watering deprivation was imposed on seedlings, resulting in well-watered (WW) and water-stressed (WS) treatments, and their water relations were assessed from pressure-volume (P-V) curves. Leaf predawn water potential (Ψpd) significantly decreased in WS seedlings which was followed by a drop in leaf osmotic potential at full turgor (Ψπ100). The lowest values of Ψπ100 followed the ranking of decreasing drought tolerance Q. ilex less then Q. faginea less then Q. pyrenaica less then Q. petraea. The leaf osmotic potential at the turgor loss point (ΨTLP) followed the same pattern as Ψπ100 across species and treatments.
