Patent ductus venosus is a congenital portosystemic shunt that may cause progressive portal hypertension, hepatic encephalopathy, and focal nodular hyperplasia of the liver. Embolization of the Arantius' duct is the first choice of treatment in infants and children. However, it carries the risk of coil migration into the systemic circulation in adult patients with larger Arantius ducts.

Objective: Currently, the two methods used to preserve lungs from uncontrolled donation after circulatory death-topical cooling and inflation-result in the suboptimal utilization of lungs. This study aimed to introduce an approach that combines cooling and inflation to investigate whether it improves lung conditions in a swine model, even if the lungs had been damaged with long-term warm ischemia, such as in out-of-hospital cardiac arrest.
Methods: Donor lungs subjected to 1.
The rapid diffusion of membrane lipids and membrane proteins in living cell plasma membranes demonstrates that the membrane is fluid. However, motion of membrane molecules is inhibited on one side by the cytoskeletal mesh, and on the other by the glycocalyx, a layer of proteoglycans with long polysaccharide chains that covers the membrane surface. A variety of biological fluid flows (including blood circulation, cilia-driven flows, and swimming motion of microorganisms) apply shear stress to cell surfaces.

Platelets in peripheral blood critically drive clot formation in health and disease. Previously considered to uniformly respond to vascular injury and inflammatory cues, recent studies have highlighted that circulating platelets exhibit marked heterogeneity, with distinct populations contributing differentially to hemostasis, thrombosis, and inflammation. In this Review, we highlight platelet diversity as a consequence of origin (i.
