The ubiquitin E2 variant domain of TSG101 (TSG101-UEV) plays a pivotal role in protein sorting and virus budding by recognizing PTAP motifs within ubiquitinated proteins. Disruption of TSG101-UEV/PTAP interactions has emerged as a promising strategy for the development of host-oriented broad-spectrum antivirals with low susceptibility to resistance. TSG101 is a challenging target characterized by an extended and flat binding interface, low affinity for PTAP ligands, and complex binding energetics.

Impacts of the acid mine drainage (AMD) remediation are investigated on the largest gold mine in Latin America, located in the Dominican Republic. Geochemical analysis of suspended matter in water performed in 2022 on water bodies located downstream to the mine, namely, the Margajita River and Lake Hatillo, are compared with analyses made in 2007, before the AMD remediation. The results for the Margajita River show a strong decrease in heavy metal and metalloid concentrations in the dissolved phase for Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Sb, and Pb (between 89.

Background: Large-scale trials evaluating a multicomponent lifestyle intervention aimed at weight loss on kidney function are lacking.

Methods: This was a post hoc analysis of the "PREvención con DIeta MEDiterránea-Plus" (PREDIMED-Plus) randomized controlled trial, including patients with overweight/obesity and metabolic syndrome, measured cystatin C and creatinine. Participants were randomly assigned (1:1) to an intensive weight loss lifestyle intervention (intervention group [IG]) consisting of an energy-restricted Mediterranean diet (MedDiet), physical activity promotion and behavioral support, or a control group (CG) receiving ad libitum MedDiet recommendations.

Hantavirus Pulmonary Syndrome (HPS) is a Pan-American emerging infectious disease with a high mortality rate caused by rodent-borne viruses of the genus Orthohantavirus. In Argentina, almost half of the HPS infections occur in the northwestern endemic region. In this study, we evaluated rodent composition, abundance, and antibody prevalence in wild rodents in three subtropical sites: primary forest, secondary forest, and crop fields.

Significance: Cellular metabolic dynamics can occur within milliseconds, yet there are no optimal tools to spatially and temporally capture these events. Autofluorescence imaging can provide metabolic information on the cellular level due to the intrinsic fluorescence of reduced nicotinamide adenine dinucleotide (phosphate) [NAD(P)H] and flavin adenine dinucleotide (FAD).

Aim: Our goal is to build and evaluate a widefield microscope optimized for rapid autofluorescence imaging of metabolic changes in cells.
