Enteroinvasive bacterial pathogens are responsible for an enormous worldwide disease burden that critically affects the young and immunocompromised. is a Gram-negative enteric pathogen, closely related to the plague agent , that colonizes intestinal tissues, induces the formation of pyogranulomas along the intestinal tract, and disseminates to systemic organs following oral infection of experimental rodents. Prior studies proposed that systemic tissues were colonized by a pool of intestinal replicating bacteria distinct from populations within Peyer's patches and mesenteric lymph nodes.

Furthermore, we hypothesized that patients undergoing primary TKA would have lower costs in the year following surgery than if patients continued nonoperative treatment. The purpose of this study was to determine the costs of various nonoperative treatment modalities in the year before and following primary TKA.

Endoscopic procedures are aerosolizing procedures that carry the risk of COVID-19 transmission. Our national survey examined factors affecting gastroenterologists' fear of contracting COVID-19 during endoscopy.

The T=3 icosahedral capsid is composed of 180 copies of ~58 kDa VP1 that has N-terminal (N), shell (S) and C-terminal protruding (P) domains. In phosphate buffered saline, the P domains are loosely tethered to the shell and float ~15Å above the surface.

The global prevalence of metabolic diseases, including diabetes, chronic liver disease, cardiometabolic disease and kidney disease, has surged in recent decades, contributing significantly to population mortality. Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease, is a leading cause of liver disease worldwide.
