Introduction: Hemodynamic forces play a crucial role in modulating endothelial cell (EC) behavior, significantly influencing blood vessel responses. While traditional in vitro studies often explore ECs under static conditions, ECs are exposed to various hemodynamic forces in vivo. This study investigates how wall shear stress (WSS) influences EC metabolism, focusing on the interplay between WSS and key metabolic pathways.

Background: Non-alcoholic steatohepatitis (NASH), an advanced manifestation of non-alcoholic fatty liver disease (NAFLD), is characterized by hepatocyte injury, inflammation, and fibrosis. Saturated fatty acids (SFAs) have emerged as key contributors to hepatocyte lipotoxicity and disease progression. Toll-like receptor 4 (TLR4) acts as a sentinel for diverse ligands, including lipopolysaccharide (LPS) and endogenous molecules like palmitic acid (PA)-induced ceramide (CER) accumulation, promoting hepatocyte demise.

In this work, coixalkyne A (), a natural polynuclear calcium complex with a novel cross-shaped molecular architecture, was isolated from L. along with the undescribed analogue coixalkyne B (). Their structures were identified by means of NMR spectroscopy, ECD calculations, and single-crystal X-ray diffraction.

Carbon-14 (C-14) has been a major contributor to the human radioactive exposure dose, as it is released into the environment from the nuclear industry in larger quantities compared to other radionuclides. This most abundant nuclide enters the biosphere as organically bound C-14 (OBC-14), posing a potential threat to public health. Yet, it remains unknown how this relatively low radiotoxic nuclide induces health risks via chemical effects, such as isotope effect.

Objective: Fibroblast-like synoviocytes (FLS) are key players in rheumatoid arthritis (RA) by resisting apoptosis via increased autophagy. Elevated synovial aquaporin 1 (AQP1) affects RA FLS behaviors, but its relationship with FLS autophagy is unclear. We aim to clarify that silencing AQP1 inhibits autophagy to exert its anti-RA effects.
