Regional fat distribution and cardiometabolic risk in healthy postmenopausal women.

Background: Regional fat distribution is an important determinant of cardiometabolic risk after menopause. The aim of the present study was to investigate the association between indices of fat distribution obtained by Dual-energy X-ray Absorptiometry (DXA) and representative cardiometabolic risk factors in a cohort of healthy postmenopausal women.

Methods: In this cross-sectional study, cardiometabolic risk factors were correlated with a variety of central and peripheral fat depots obtained by DXA, in a total of 150 postmenopausal women, free of diabetes and cardiovascular disease (age 54 ± 7 years, BMI 29.

Body composition determinants of metabolic phenotypes of obesity in nonobese and obese postmenopausal women.

Objective: Although obesity is typically associated with increased cardiovascular risk, a subset of obese individuals display a normal metabolic profile ("metabolically healthy obese," MHO) and conversely, a subset of nonobese subjects present with obesity-associated cardiometabolic abnormalities ("metabolically obese nonobese," MONO). The aim of this cross-sectional study was to identify the most important body composition determinants of metabolic phenotypes of obesity in nonobese and obese healthy postmenopausal women.

Design And Methods: We studied a total of 150 postmenopausal women (age 54 ± 7 years, mean ± 1 SD).

Association of lean body mass with cardiometabolic risk factors in healthy postmenopausal women.

Objective: Aim of this study was to investigate the association of total and regional lean body mass (LBM) with cardiometabolic risk factors in healthy obese and nonobese postmenopausal women.

Methods: A total of 150 postmenopausal women (age 54 ± 7 years, BMI 29.6 ± 5.

Insulin resistance and metabolic syndrome in patients with nonfunctioning adrenal incidentalomas: a cause-effect relationship?

The objective of the study was to assess insulin resistance (IR) and metabolic syndrome (MS) in patients with nonfunctioning adrenal incidentalomas (NFAIs). Among a total cohort of 46 patients with adrenal incidentalomas, we studied 29 patients with NFAIs (mean age, 54 ± 9 years; body mass index, 29 ± 3 kg/m(2)) and 37 age-, sex-, and body mass index-matched healthy controls. Besides the endocrine workup, IR was evaluated using fasting glucose and insulin concentrations, homeostasis model assessment of IR, and quantitative insulin sensitivity check index.

Neonatal handling on the first postnatal day leads to increased maternal behavior and fos levels in the brain of the newborn rat.

In the present work we employed Fos expression, an index of neuronal activity, to identify brain areas activated by a single exposure to "neonatal handling" on postnatal Day 1. Eight hours following "handling" there was an increase in the number of Fos positive cells in the hippocampus, the parietal and occipital cortex. We also recorded maternal behavior during the 8 hr following "handling.

Cellular mechanisms underlying an effect of "early handling" on pCREB and BDNF in the neonatal rat hippocampus.

Early experiences have long-term effects on brain function and behavior. However, the precise mechanisms involved still remain elusive. In an effort to address this issue, we employed the model of "early handling", which is known to affect the ability of the adult organism to respond to stressful stimuli, and determined its effects on hippocampal pCREB and BDNF 2, 4, and 8 h later.

Cellular mechanisms underlying the effects of an early experience on cognitive abilities and affective states.

Unlabelled: In the present study we investigated the effects of neonatal handling, an animal model of early experience, on spatial learning and memory, on hippocampal glucocorticoid (GR), mineralocorticoid (MR) and type 1A serotonin (5-HT1A) receptors, as well as brain derived neurotrophic factor (BDNF), and on circulating leptin levels, of male rats.

Method: Spatial learning and memory following an acute restraint stress (30 min) were assessed in the Morris water maze. Hippocampal GR, MR and BDNF levels were determined immunocytochemically.
