The aim of this study was to evaluate the effects of increasing doses of ascorbic acid (AA) and citric flavonoids (quercetin and rutin) on the performance and meat quality characteristics of broilers submitted to cyclic heat stress. Four-hundred one-day-old female Ross 308 were housed in 40 battery cages a in temperature controlled room. Treatments consisted of 0, 250, 500, and 1000 g/ton on of...

background: this work aimed to show and compare the degradation time of some of cartilage extracellular matrix components using an in vitro model for cartilage degradation induced by interleukin-1 alpha. it is known that elucidation of molecular events under interleukin-1 alpha induction of bovine nasal cartilage could obtain useful data to understand more about involving mechanisms for tissue ...

During the first two postnatal weeks the amount of RNA of the pancreatic cells evaluated biochemically is about 3 times lower than that of the cells in the adult rat. Accordingly, in the acinar cells the amount of rough membranes of endoplasmic reticulum and the fraction of the cell volume occupied by the RNAase removable basophilic substance are visibly lower than those of the adult. Radioauto...

this study evaluated the effect of the intermittent light program on serum and brain melatonin concentrations, antioxidant enzyme activities, and homocysteine concentration in broiler chickens. a total of 60 one-day-old broiler chickens (cobb 500) were distributed in three light-proof controlled rooms (20 chicks per room). all birds were reared in continuous light until 3 days of age. then, chi...

background: pregnancy associated osteoporosis (pao) can lead to serious difficulties such as fragility fractures, elongated back pain and height loss in affected women. soluble receptor activator of nuclear factor-kappa b ligand (srankl) to osteoprotegerin (opg) ratio is chosen as a bone metabolism equation in many bone diseases characterized by bone resorption, such as post-menopausal osteopor...
