Case Report of snare-assisted coaxiality optimized technique during valve deployment in patient with pure aortic regurgitation.

In high-risk patients with pure native aortic regurgitation (PNAR), transcatheter aortic valve replacement (TAVR) remains an off-label intervention. Due to anatomical variations in the aortic root and technical challenges unique to PNAR, the transfemoral approach (TF-TAVR) requires continued accumulation of experience and technological refinement. In this context, we successfully and safely performed a snare-assisted TF-TAVR procedure for a patient with PNAR, characterized by significant aortic angulation.

Quantitative Data-Independent Acquisition Mass Spectrometry Proteomics and Weighted Correlation Network Analysis of Plasma Samples for the Discovery of Chronic Kidney Disease-Specific Atherosclerosis Risk Factors.

Multicystic peritoneal mesothelioma (MCPM) is a rare neoplasm, predominantly affecting female patients during their reproductive years. The lesion is usually distributed diffusely in the abdomen and pelvis, but the peritoneum of the pelvic organs is the most common site. MCPM is composed of fluid-filled translucent cysts, connected by varying amounts of fibrous tissue, and lined by a layer of mesothelial cells.

Bone marrow-derived mesenchymal stem cells increase drug resistance in CD133-expressing gastric cancer cells by regulating the PI3K/AKT pathway.
