Hexafluoroisopropanol as a Bioconjugation Medium of Ultrafast, Tryptophan-Selective Catalysis.

The past decade has seen a remarkable growth in the number of bioconjugation techniques in chemistry, biology, material science, and biomedical fields. A core design element in bioconjugation technology is a chemical reaction that can form a covalent bond between the protein of interest and the labeling reagent. Achieving chemoselective protein bioconjugation in aqueous media is challenging, especially for generally less reactive amino acid residues, such as tryptophan.

"Like a tsunami coming in fast": A critical qualitative study of precarity and resistance during the pandemic.

This study explores the nature of precarity via the lens of the coronavirus disease (COVID-19) pandemic. Precarity refers to uncertainty, loss, disruption, and anxiety, which differentially impact people across contexts. We sought to (a) identify how people understand and resist precarity during the pandemic; (b) explore the potential of precarity to serve as an organizing concept for psychological praxis and research; and (c) explore ways in which psychology of working theory (PWT) may be enriched by an infusion of precarity into its theoretical tenets.

Prevalence of SARS-CoV-2 Contamination on Food Plant Surfaces as Determined by Environmental Monitoring.

Abstract: The SARS-CoV-2 pandemic has presented new challenges to food manufacturers. During the early phase of the pandemic, several large outbreaks of coronavirus disease 2019 (COVID-19) occurred in food manufacturing plants resulting in deaths and economic loss, with approximately 15% of personnel diagnosed as asymptomatic for COVID-19. Spread by asymptomatic and presymptomatic individuals has been implicated in large outbreaks of COVID-19.

Pilot Study Evaluating Critical Time Intervention for Individuals With Hoarding Disorder at Risk for Eviction.

Hoarding disorder has significant health consequences, including the devastating threat of eviction. In this pilot study, critical time intervention (CTI), an evidence-based model of case management shown to be effective for vulnerable populations, was adapted for individuals with severe symptoms of hoarding disorder at risk for eviction (CTI-HD). Of the 14 adults who enrolled, 11 participants completed the 9-month intervention.

H3K4 demethylase activities repress proliferative and postmitotic aging.

Homeostasis of postmitotic and proliferating cells is maintained by pathways that repress stress. We found that the Caenorhabditis elegans histone 3 lysine 4 (H3K4) demethylases RBR-2 and SPR-5 promoted postmitotic longevity of stress-resistant daf-2 adults, altered pools of methylated H3K4, and promoted silencing of some daf-2 target genes. In addition, RBR-2 and SPR-5 were required for germ cell immortality at a high temperature.
