This study aims to determine the effects of maternal protein and energy malnutrition during lactation on the linear growth, body weight and onset of puberty of the female offspring. At parturition, dams were randomly assigned to the following groups: (C) control group, with free access to a standard laboratory diet containing 23% protein; (PR)(More)
BACKGROUND The effect of in vivo treatment with ursolic acid (UA) on glycemia in hyperglycemic rats and its mechanism of action on muscle were studied. METHODS The UA effects on glycemia, glycogen, LDH, calcium and on insulin levels were evaluated after glucose tolerance curve. The β-cells were evaluated through the transmission electron microscopy. UA(More)
OBJECTIVE The goal of this study was to evaluate if maternal malnutrition during lactation could possibly program folliculogenesis, the ovarian expression of gonadotropins, leptin, and their receptors. METHODS At parturition, dams were randomly assigned to a control group (C), with free access to a standard laboratory diet containing 23% protein, and a(More)
The aim of this study was to evaluate testosterone concentrations, sexual behavior, and androgen receptor protein level in the testes of rats submitted to protein- and energy-restricted diets during 30 days. Adult male Wistar rats were assigned to one of the following groups: (C) control, diet with 23% of protein; (PR) protein-restricted, diet with 8% of(More)
OBJECTIVES The aim of this study was to compare the effects of a prolonged use of organic and transgenic soy upon the lipid profile and the collagen/muscle ratio of the detrusor muscle of the bladder. METHODS Wistar rats were fed three different diets from weaning until sacrifice (15 months old): control group (CG) casein-based diet; organic soy group(More)
Both protein-energy and energy-restricted diets during lactation program the ovarian function of the rat offspring, leading to a reduction of folliculogenesis, possibly as the consequence of the altered expression of leptin and its isoform receptor genes.
PURPOSE We evaluated whether antihypertensive drugs that act through the renin-angiotensin system would affect testis function. MATERIALS AND METHODS Ten mice were fed standard chow and 40 received a high energy density diet. At 8 weeks the high energy density diet mice were divided into 4 groups of 10 each. The untreated group received the high energy(More)
Hypothyroidism is a condition in which the serum levels of thyroid hormones are below that necessary to carry out physiological functions in the body. Hypothyroidism is related to obesity as an increase in body weight gain is seen in hypothyroid patients. Moreover, an inverse correlation between free thyroxine values and body mass index has been reported.(More)
The leptin hormone is important to satiety and an important link between the nutritional status and reproductive processes. Owing to the contradictory effects of leptin on the ovary and the failure to clarify the precise mechanism by which leptin affects the ovary, our aim was to contribute to evaluation if leptin can directly regulate the gene expression(More)
