Cerebral vascular dysfunction during hypercholesterolemia.
BACKGROUND AND PURPOSE Studies of peripheral arteries in hypercholesterolemic animals suggest that increased generation of superoxide contributes to endothelial dysfunction, especially in the presence of atherosclerotic lesions. We tested the hypothesis that vasomotor function is impaired in cerebral arterioles during hypercholesterolemia through a mechanism that involves oxidative stress. ME...
متن کاملAugmented superoxide production by Nox2-containing NADPH oxidase causes cerebral artery dysfunction during hypercholesterolemia.
BACKGROUND AND PURPOSE We tested the hypothesis that elevated superoxide production by Nox2-NADPH oxidase occurs in cerebral arteries during hypercholesterolemia and causes decreased nitric oxide function. METHODS Wild-type (WT), apolipoprotein E-deficient (ApoE(-/-)) and Nox2(-/-)/ApoE(-/-) mice were fed a high-fat diet for 7 to 14 weeks. Basal superoxide production by cerebral arteries was ...
متن کاملHyperhomocysteinemia, oxidative stress, and cerebral vascular dysfunction.
An elevated circulating concentration of the sulfurcontaining amino acid homocysteine, hyperhomocysteinemia, produces complex changes within the blood vessel wall. In the peripheral circulation, these changes include oxidative stress, proinflammatory effects such as expression of tumor necrosis factorand inducible nitric oxide (NO) synthase (iNOS), and endothelial dysfunction.1–6 Hyperhomocyste...
متن کاملSelective head cooling during neonatal seizures prevents postictal cerebral vascular dysfunction without reducing epileptiform activity.
Epileptic seizures in neonates cause cerebrovascular injury and impairment of cerebral blood flow (CBF) regulation. In the bicuculline model of seizures in newborn pigs, we tested the hypothesis that selective head cooling prevents deleterious effects of seizures on cerebral vascular functions. Preventive or therapeutic ictal head cooling was achieved by placing two head ice packs during the pr...
متن کاملMeibomian Gland Dysfunction and Hypercholesterolemia
High cholesterol is a known risk factor for ischemic heart, cerebrovascular, and peripheral vascular disease. Previous studies have postulated that hypercholesterolemia (defined as total cholesterol of at least 200 mg/dL) also plays a role in the development of meibomian gland dysfunction (MGD). In this observational, case-control study, Pinna et al. investigated the correlation between MGD and...
