TSST-1 promotes colonization of within the vaginal tract by activation of CD8 T cells.

Toxic shock syndrome toxin-1 (TSST-1) is a superantigen produced by and is the determinant of menstrual toxic shock syndrome (mTSS); however, the impact of TSST-1 on the vaginal environment beyond mTSS is not understood. Herein, we assessed how TSST-1 affects vaginal colonization by , host inflammatory responses, and changes in microbial communities within the murine vagina. We demonstrated that TSST-1 induced a CD8 T-cell-dependent inflammatory response in 24 h that correlated with persistence within the vaginal tract.

Short-Term Warm-Water Immersion for Improving Whole-Body Heat Loss in Older Men.

Purpose: Exercise-induced heat acclimation can mitigate age-related reductions in heat-loss capacity, though performing repeated bouts of strenuous exercise in the heat may be untenable for many older adults. While short-term passive heat acclimation (e.g.

Human Papilloma Virus Infection and Sinonasal Inverted Papilloma Recurrence: A Meta-Analysis.

Objective: Prior studies have been contradictory on the role of human papillomavirus (HPV) infection in sinonasal inverted papilloma (SNIP) recurrence. This systematic review and meta-analysis was performed to further evaluate this potential association.

Familial Hyperkalemic Hypertension.

The rare disease Familial Hyperkalemic Hypertension (FHHt) is caused by mutations in the genes encoding Cullin 3 (CUL3), Kelch-Like 3 (KLHL3), and two members of the With-No-Lysine [K] (WNK) kinase family, WNK1 and WNK4. In the kidney, these mutations ultimately cause hyperactivation of NCC along the renal distal convoluted tubule. Hypertension results from increased NaCl retention, and hyperkalemia by impaired K secretion by downstream nephron segments.

A prognostic molecular signature of hepatic steatosis is spatially heterogeneous and dynamic in human liver.

Hepatic steatosis is a central phenotype in multi-system metabolic dysfunction and is increasing in parallel with the obesity pandemic. We use a translational approach integrating clinical phenotyping and outcomes, circulating proteomics, and tissue transcriptomics to identify dynamic, functional biomarkers of hepatic steatosis. Using multi-modality imaging and broad proteomic profiling, we identify proteins implicated in the progression of hepatic steatosis that are largely encoded by genes enriched at the transcriptional level in the human liver.
