Carotid endarterectomy open. In several clinical trials, the 30-day incidence of heart attack, stroke, or death was significantly higher with stenting than with endarterectomy (9.6% vs. 3.9%). The Carotid Revascularization Endarterectomy versus Stenting Trial (CREST) funded by the National Institutes of Health (NIH) reported that the results of stents and endarterectomy were comparable. However, the European International Carotid Stenting Study (ICSS) found that stents had almost double the rate of complications. The aim of CEA is to prevent the adverse sequelae of carotid artery stenosis secondary to atherosclerotic disease, i.e. ischemic stroke. As with any prophylactic operation, careful evaluation of the relative
Human body as multicellular organisms which reside in the gastrointestinal tract and on the skin. Not all parts of the body are made from cells. Cells sit in an extracellular matrix that consists of proteins such as collagen, surrounded by extracellular fluids. Of the 70 kg weight of an average human body, nearly 25 kg is non-human cells or non-cellular material such as bone and connective tissue. Cells in the body function because of DNA. DNA sits within the nucleus of a cell. Here, parts of DNA are copied and sent to the body of the cell via RNA. The RNA is
