BACKGROUND Matrix metalloproteinase-9 (MMP9) is expressed in acute ischemic stroke and up-regulated by tissue plasminogen activator (tPA) in animal models. The authors investigated plasma MMP9 and its endogenous inhibitor, tissue inhibitor of metalloproteinase (TIMP1), in tPA-treated and -untreated stroke patients. METHODS Nonstroke control subjects and(More)
BACKGROUND Although hyperhomocyst(e)inemia (Hyper-Hcy) may predispose to atherosclerosis and venous thrombosis, the mechanisms of stroke associated with Hyper-Hcy are not defined. METHODS Clinical and biochemical phenotypes and genetic features of three unrelated patients with premature stroke and severe Hyper-Hcy due to cystathionine beta-synthase (CBS)(More)
A low blood glucose level is associated with impairment of higher cerebral function and an increase in cerebral blood flow. This study examined whether there are differences in the physiological responses to hypoglycaemia between the cerebral hemispheres. Eight healthy men participated in two hyperinsulinaemic glucose clamp studies: after 60 min at 4.5(More)
