The secretion and the blood levels of the adrenal steroid dehydroepiandrosterone (DHEA) and its sulfate ester (DHEAS) decrease profoundly with age, and the question is posed whether administration of the steroid to compensate for the decline counteracts defects associated with aging. The commercial availability of DHEA outside the regular(More)
The menopause is associated with changes in body composition: a decline in bone mineral content, a decrease in collagen synthesis, a loss of lean body mass and an increase in total and abdominal fat mass. Oestrogen deficiency seems to play a role in the menopause-related changes in body composition, but life styles (diet, exercise, smoking habits, alcohol(More)
OBJECTIVE To search the human ob gene for mutations and evaluate their role in massive obesity. DESIGN Direct mutation screening of the gene and case-control association study. Multivariate analyses for evaluation of differences in clinical parameters. SUBJECTS Primary mutation screening: 24 morbidly obese subjects (body mass index (BMI) > 40 kg/m2).(More)
Leptin, the ob gene product, is considered as a signal involved in the regulation of energy stores through centrally mediated effects on ingestive behavior and metabolism. To investigate the relationships between appetite-related sensations and circulating leptin in humans, 12 healthy male volunteers were served two test lunches (1200 kcal, 38%(More)
Adipose tissue lipoprotein lipase (LPL) activity was determined in the abdominal and femoral regions in 25 pre- and 25 post-menopausal obese women, matched for body mass index and fat distribution. LPL activity was not different in pre- and post-menopausal women. Regional differences of the same magnitude were observed in pre- and post-menopausal women with(More)
The association of fats with carbohydrates results in a lower glucose response but the influence of the nature of the dietary fatty acids has not been investigated clearly. We examined the effect of the degree of dietary fatty acid unsaturation on the postprandial glucose and insulin responses to a mixed meal. Eight young normolipidemic men consumed four(More)
The objective of this study was to investigate body perception and the associated level of dissatisfaction among obese patients. Twenty patients from each category of obese, severely obese, and normal weight individuals had their pictures enlarged or thinned using a computer program to manipulate photographs taken from the front, profile angle, and back.(More)
OBJECTIVES Whether menopause per se influences fat distribution independently of the effect of aging remains controversial. The lack of consistency in the menopause related changes in body fat distribution may be the result of differences in the methods for measuring fat distribution or in the characteristics of the women studied. The aim of this cross(More)
