Tetrahydrobiopterin restores endothelial function in hypercholesterolemia.
In hypercholesterolemia, impaired nitric oxide activity has been associated with increased nitric oxide degradation by oxygen radicals. Deficiency of tetrahydrobiopterin, an essential cofactor of nitric oxide synthase, causes both impaired nitric oxide activity and increased oxygen radical formation. In this study we tested whether tetrahydrobiopterin deficiency contributes to the decreased nit...
متن کاملCongenital generalized lipodystrophy.
Clinical features of congenital generalized lipodystrophy, a rare disorder, first described by Zeigler include loss of subcutaneous fat, hepatomegaly, increased bone growth, hyperlipaemia and, later, diabetes. The inheritance is probably autosomal recessive. Generalized lipodystrophy may involve the diencephalon. A probable defect in the hypothalamus may lead to increased levels of hypothalamic...
متن کامل[Congenital generalized lipodystrophy].
OBJECTIVE To present the major clinical and biochemical characteristics of congenital generalized lipodystrophy. DESCRIPTION Eight infants with congenital generalized lipodystrophy were identified at the Endocrine and Nutritional Pediatric Disease Outpatient Clinics at Hospital de Clínicas, Universidade Federal de Minas Gerais (UFMG). Clinical manifestations common to all patients included mu...
متن کاملEndothelial Function in a Mouse Model of Myeloperoxidase Deficiency
Myeloperoxidase (MPO) activity is suggested to reduce the function of vascular nitric oxide, thereby contributing to endothelial dysfunction, although data in rodents are inconclusive. We examined vascular contractile and relaxant responses in MPO-deficient (MPO(-/-)) and wild-type mice to investigate the role for myeloperoxidase in the development of endothelial dysfunction. Carotid and saphen...
متن کاملEndothelial function is impaired in HIV-infected patients with lipodystrophy.
BACKGROUND Data supporting a link between body-fat distribution changes and cardiovascular disease risk in HIV-infected patients are scarce and contradictory. We evaluated endothelial dysfunction, an early event in the development of atherosclerosis, and pro-atherosclerotic plasma biomarkers in HIV-infected patients with lipodystrophy. METHODS HIV-infected patients with and without lipodystro...
