Recent theoretical work has argued that moral psychology can be understood through the lens of "resource rational contractualism." The view posits that the best way of making a decision that affects other people is to get everyone together to negotiate under idealized conditions. The outcome of that negotiation is an arrangement (or "contract") that would lead to mutual benefit.

During the COVID-19 pandemic, the sampling method for the National HIV Behavioral Surveillance (NHBS) in San Francisco changed from physical venue time-location sampling (TLS) to online or virtual venue TLS for men who have sex with men (MSM). We present differences in the samples of MSM recruited using physical venue TLS in 2017 and virtual venue TLS in 2021. We further assess changes in preventive and risk behaviors from 2017 to 2021 after controlling for differences in the sample compositions with multivariable Poisson models using GLM with robust standard errors.

Article Synopsis
  • Trichomonas vaginalis (Tv) is a protozoan parasite that causes trichomoniasis, the most prevalent non-viral sexually transmitted infection globally, but current treatment options are limited and facing resistance issues.
  • Researchers are targeting the proteasome, a key enzyme complex in eukaryotes, to develop new treatments by isolating the enzyme and identifying specific inhibitors for its three catalytic subunits (β1, β2, β5).
  • By creating specialized substrates for each subunit and screening a library of inhibitors, the study found that targeting the Tv β5 subunit is particularly effective in killing the parasite, which may lead to improved drug development strategies against trichomoniasis.

Rhomboid proteases are ubiquitous intramembrane serine proteases that can cleave transmembrane substrates within lipid bilayers. They exhibit many and diverse functions, such as but not limited to, growth factor signaling, immune and inflammatory response, protein quality control, and parasitic invasion. Human rhomboid protease RHBDL4 has been demonstrated to play a critical role in removing misfolded proteins from the Endoplasmic Reticulum and is implicated in severe diseases such as various cancers and Alzheimer's disease.

Objective: To evaluate the effect of curricular content reduction in an integrated course sequence spanning 3 years of a Doctor of Pharmacy curriculum on student examination scores and course grades.

Methods: This 2-year, prepost study compared student overall average and final examination scores and overall course grades after the transition from a 5-day to a 4-day week of an integrated learning experience (ILE) course sequence. In addition, an anonymous, optional 23-item survey was distributed to first to third year pharmacy students asking about the 4-day week change, how they utilized the non-ILE day, and additional demographic and social characteristics to identify factors influencing success on examination and course performance during the 4-day week.

Introduction: Common mental health conditions (CMHCs), including depression, anxiety and post-traumatic stress disorder (PTSD), are highly prevalent in low and middle-income countries (LMICs). Preventive strategies combining psychological interventions with interventions addressing the social determinants of mental health may represent a key strategy for effectively preventing CMHCs. However, no systematic reviews have evaluated the effectiveness of these combined intervention strategies for preventing CMHCs.

Modulating the metabolism of cancer cells, immune cells, or both is a promising strategy to potentiate cancer immunotherapy in the nutrient-competitive tumor microenvironment. Glutamine has emerged as an ideal target as cancer cells highly rely on glutamine for replenishing the tricarboxylic acid cycle in the process of aerobic glycolysis. However, non-specific glutamine restriction may induce adverse effects in unconcerned tissues and therefore glutamine inhibitors have achieved limited success in the clinic so far.

Six monomeric (1a-1f) and five dimeric (2a-2e) derivatives of the triphenylmethane dye crystal violet (CV) have been prepared. Evaluation of the binding of these compounds to CT DNA by competitive fluorescent intercalator displacement (FID) assays, viscosity experiments, and UV and CD spectroscopy suggest that monomeric derivative 1a and dimeric derivative 2d likely associate with the major groove of DNA, while dimeric derivatives 2a and 2e likely associate with the minor groove of DNA. Additional evidence for the groove occupancy assignments of these derivatives was obtained from ITC experiments and from differential inhibition of DNA cleavage by the major groove binding restriction enzyme BamHI, as revealed by agarose gel electrophoresis.
