The effect of intracerebroventricular or intraperitoneal administration of cannabinoid receptor agonist WIN 55,212-2 or inverse agonist AM 251 on food intake and extracellular levels of serotonin and acetic acid 5-hydroxy-indol from presatiated rats was studied. Compared to the vehicle-injected control, the intracerebroventricular administration of WIN(More)
Environmental pollution by phosphorus from animal waste is a major problem in agriculture because simple-stomached animals, such as swine, poultry, and fish, cannot digest phosphorus (as phytate) present in plant feeds. To alleviate this problem, a phytase from Aspergillus niger PhyA is widely used as a feed additive to hydrolyze phytate-phosphorus.(More)
OBJECTIVE We assessed the effect of germinating Pisum sativum L. variant Arvense cv. Esla for 3 and 6 d in darkness on the chemical composition and nutritive utilization of protein and carbohydrates. METHODS Nutritional assessment of protein and carbohydrates was based on chemical analysis of raw and germinated pea flours and in vitro and in vivo rat(More)
INTRODUCTION Dietary protein amount and source, hypertrophy resistance training (RT) and anabolicandrogenic steroids (AAS) may affect body weight and plasma and hepatic lipid profile. MATERIAL AND METHODS 157 adult male Wistar rats were randomly distributed in 16 experimental groups resulting in: normal-protein (NP) or high-protein (HP) diets, whey or(More)
The effect of mild hydrothermal treatment and the addition of phytase under optimal conditions (pH 5.5, 37 degrees C) on the nutritive utilization of the protein of pea (Pisum sativum L.) flour was studied in growing rats by examining the chemical and biological balance. Mild hydrothermal treatment produced reductions of 83, 78, and 72%, respectively, in(More)
OBJECTIVE The effects of heat treatment, supplementation of a mineral and vitamin premix, and 4% olive oil on the bioavailability of protein and calcium from Lens culinaris M., var vulgaris, cultivar. magda-20 were studied in growing rats. METHODS Nutrition assessment was based on chemical analysis of lentil protein, energy, total and available starch,(More)
UNLABELLED BACKGROUND Quercetin is a natural polyphenolic compound currently under study for its ergogenic capacity to improve mitochondrial biogenesis. Sedentary mice have exhibited increased endurance performance, but results are contradictory in human models. METHODS We examined the effects of six weeks of endurance training and quercetin(More)
The effect of autoclave treatment on the digestive utilisation of protein and amino acids from lentils was studied in growing rats. Twenty 3-week-old Wistar rats (mean live weight 59 AE 4.8 g) were fed two experimental diets (n = 10 rats per diet) consisting of raw lentils (Lens culinaris M, var vulgaris, cv magda-20) (diet RL) or lentils autoclaved at 120(More)
INTRODUCTION High-protein (HP) diets might affect renal status. We aimed to examine the effects of a HP diet on plasma, urinary and morphological renal parameters in rats. MATERIAL AND METHODS Twenty Wistar rats were randomly distributed in 2 experimental groups with HP or normal-protein (NP) diets over 12 weeks. RESULTS AND DISCUSSION Final body weight(More)
INTRODUCTION It is well established that soy protein diets as well as aerobic exercise could promote antioxidant capacity and consequently reduce free radicals overproduction on brain. However, little is know regarding to the high-protein diets and high intensity exercise on oxidative stress production. The aim of this study was to analyse the effects of(More)
