Congenital generalized lipodystrophy, or Berardinelli-Seip syndrome (BSCL), is a rare autosomal recessive disease characterized by a near-absence of adipose tissue from birth or early infancy and severe insulin resistance. Other clinical and biological features include acanthosis nigricans, hyperandrogenism, muscular hypertrophy, hepatomegaly, altered(More)
Generalised lipodystrophy of the Berardinelli-Seip type (BSCL) is a rare autosomal recessive human disorder with severe adverse metabolic consequences. A gene on chromosome 9 (BSCL1) has recently been identified, predominantly in African-American families. More recently, mutations in a previously undescribed gene of unknown function (BSCL2) on chromosome(More)
Antioxidants probably play an important role in the etiology of type 2 diabetes (DM2). This study evaluated the effects of supplementation with lipoic acid (LA) and α-tocopherol on the lipid profile and insulin sensitivity of DM2 patients. A randomized, double-blind, placebo-controlled trial involving 102 DM2 patients divided into four groups to receive(More)
Type 2 diabetes mellitus (DM2) predisposes to an increased production of free radicals and a probable reduction in plasma antioxidants, including vitamin E. This cross-sectional study investigated the relationship between plasma alpha-Tocopherol concentration and vitamin E intake in 58 Brazilians with DM2. Plasma alpha-Tocopherol was determined by(More)
Specific binding of hGH to liver microsomes of nonpregnant women and men is low, usually 10% of less in RRA. In pregnant women, however, we found that this binding is 10 times higher. The binding reaction shared the properties common to receptor systems: time, temperature and cation dependence, saturability and reversibility, hGH specific binding without(More)
Serum somatomedin B (SmB) levels in cirrhotic individuals, 3.3 +/- 1.5 mg/l, were strikingly lower (P less than 0.001) than in normal subjects, 9.0 +/- 1.7 mg/l. SmB levels were clearly related to the levels of alpha 2-globulins in the cirrhotics (r = + 0.8, P less than 0.002). Serum SmB and growth hormone correlated negatively in a group of normal and(More)
A cross-sectional study was carried out to assess small (SAEI) and large (LAEI) arterial elasticity indexes of individuals with T1DM, and its relationship with their lipid profile. There were associations between SAEI and total cholesterol and waist-hip ratio (R(2)=0.29). Most of the individuals investigated showed low measures of SAEI.
