Total butyrylcholinesterase activity (EC 3.1.1.8) was previously suggested as a marker for metabolic syndrome. The present study examined total butyrylcholinesterase activity and the relative and absolute activities of two butyrylcholinesterase electrophoretic bands (C(4/5) and C(OF) in 99 obese individuals (body mass index > or = 30 kg/m2) presenting the(More)
OBJECTIVE To investigate the association between butyrylcholinesterase (BChE) activities (total and band specific) and body mass index (BMI) in obese and nonobese individuals, considering other variables (anthropometric, biochemical and hormonal) and the leanness process. SUBJECTS Obese (BMI> or =30 kg/m(2); N=181) and nonobese individuals (N=265),(More)
The butyrylcholinesterase (BChE; EC 3.1.1.8) activities of two electrophoretic bands of the CHE2 C5+ phenotype--C5 and C(OF) (other forms)--were quantified by densitometry in 100 individuals. The activity data suggested that, in addition to determining C5, the CHE2*C5+ allele also increases the level of other BChE forms. Since the relative activity of C5(More)
INTRODUCTION The aim of this study was to evaluate the reliability of self-reported HIV among men who have sex with men (MSM) in Brazil. METHODS MSM 18 years of age or older were recruited to a multicenter study using respondent-driven sampling. We compared self-report of the HIV test with a rapid HIV test using the kappa coefficient. RESULTS A total of(More)
The activity of a supposedly heteromeric complex (C4/5) of butyrylcholinesterase (BChE; EC 3.1.1.8) was analyzed in relation to body mass index (BMI). The activities of the C4/5 and C(OF) (other molecular forms) bands in CHE2 C5- (n = 447) and CHE2 C5+ (n = 88) individuals were quantified by densitometry. Since the absolute activity of C4/5 (AC4/5) showed(More)
The aim of this work was to evaluate the distribution of the entrance surface air kerma (ESAK) and the average glandular dose (D(G)) in four mammography facilities located in the city of Rio de Janeiro. The ESAK values were estimated from the X-ray tube output rate (mGy/mAs) parameters. The image quality was evaluated by the radiologists in each clinic. The(More)
This paper aims to evaluate the radiation dose exposure of patients submitted to cardiac computed tomography angiography. The effective dose was obtained from the product of dose-length product values and the conversion factor established in the European Working Group for Guidelines on Quality Criteria in CT. The image noise and contrast- and(More)
