Fetal Intra-abdominal Umbilical Vein Aneurysm.
Importance Fetal umbilical vein aneurysm is an uncommon anomaly that accounts for approximately 4% of umbilical cord abnormalities. The rate of intrauterine fetal death is reported to be approximately 4% to 5%, higher than the background rate of 0.7% that is generally reported during pregnancy. Objective The aim of this study was to review the pathophysiology, diagnosis, and clinical manageme...
متن کاملMurine model of neointimal formation and stenosis in vein grafts.
OBJECTIVE Previous studies have suggested that neointimal formation, a central cause of vein graft stenosis, has several potential cell sources. It was hypothesized that neointimal cells arise primarily from the cells of the vein graft. METHODS AND RESULTS This study investigated vein graft neointimal cell origins using a model of vein-to-artery cross-transplantation between transgenic Rosa26...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Human umbilical cord blood-derived endothelial cells reendothelialize vein grafts and prevent thrombosis.
OBJECTIVE To accelerate vein graft reendothelialization and reduce vein graft thrombosis by infusing human umbilical cord blood-derived endothelial cells (hCB-ECs) because loss of endothelium contributes to vein graft thrombosis and neointimal hyperplasia. METHODS AND RESULTS Under steady flow conditions in vitro, hCB-ECs adhered to smooth muscle cells 2.5 to 13 times more than ECs derived fr...
متن کاملAtherosclerosis in rabbit vein grafts.
Human coronary saphenous vein bypass grafts develop atherosclerosis more readily than do grafts made of internal mammary artery. The reasons for this increased susceptibility, particularly in the presence of hyperlipidemia, are not known. In this study in rabbits, we investigated the possibility that the increased susceptibility might be attributed to increased smooth muscle proliferation and f...
