The relationship between endothelial dysfunction and stroke subtypes is unclear. We prospectively measured brachial flow-mediated vasodilation (FMD) in 143 patients with acute ischemic stroke and 40 controls. The overall stroke patients had impaired FMD, but only lacunar infarction had significantly impaired FMD vs the controls. Impaired FMD was an independent predictor for lacunar infarction. Ischemic stroke is associated with endothelial dysfunction, which is more conspicuous in lacunar infarction.
Total testosterone level is significantly related to metabolic and inflammatory factors in elderly men. Low total testosterone may be a significant indicator for development of metabolic syndrome in elderly men.
Areca nut may regulate death pathways in neutrophils. This may be one mechanism by which areca nut compromises the periodontal health of areca nut chewers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
