Repeated epochs of breath-holding were superimposed to the regular training cycling program of triathletes to reproduce the adaptative responses to hypoxia, already described in elite breath-hold divers [Respir. Physiol. Neurobiol. 133 (2002) 121]. Before and after a 3-month breath-hold training program, we tested the response to static apnea and to a 1-min dynamic forearm exercise executed dur...

and Implications Irradiation dose had a significant effect on the production of volatiles in both vacuumand aerobic-packaged cooked pork sausage, but its effect on the thiobarbituric acid reactive substances (TBARS) values was minor. Storage increased the production of volatiles and changed the composition of volatiles only in aerobic-packaged sausage. Among the volatile components, 1-heptene a...

The effects of modafinil (MD) on behavioral and oxidative damage to protein and lipid in the brain of rats were evaluated. Wistar rats were given a single administration by gavage of water or MD (75, 150, or 300 mg/kg). Behavioral parameters were evaluated in open-field apparatus 1, 2, and 3 h after drug administration. Thiobarbituric acid reactive substances (TBARS) and protein carbonyl format...

The objective of this study was to evaluate the gluconeogenic response of in vitro stimulated hepatocytes from control broilers and broilers with clinical manifestations of the ascites syndrome. The basal rate of glucose synthesis from lactate was found to be threefold greater in sick birds than in the control group and stimulation obtained with epinephrine was found to be quantitatively simila...

We report "smart" nickel oxide nanoparticles (NOPs) as multimodal cancer therapy agent. Water-dispersible and light-sensitive NiO core was synthesized with folic acid (FA) connected bovine serum albumin (BSA) shell on entrapped doxorubicin (DOX). The entrapped drug from NOP-DOX@BSA-FA was released in a sustained way (64 hours, pH=5.5, dark conditions) while a robust release was found under red ...

INTRODUCTION The aim of the present study was to demonstrate the effects of aspartate on the circadian patterns of lipid peroxidation products and antioxidants in aspartate-treated rats, in order to investigate the influences of aspartate and whether it could modulate these rhythms differently, since aspartate is an important excitatory neurotransmitter (present in retinohypothalamic tract and ...

Introduction: The aim of this study was to evaluate thiobarbituric acid reactive substances (TBARS) as lipid peroxidation marker and total antioxidant capacity(TAC) in saliva of smoker and non-smoker men. Materials & Methods: This case-control study was performed on 104 men including smoker (52) and non-smoker (52) men, referred to the Oral Medicine Department in Babol Faculty o...

Spoilage of meat has remained a serious challenge in developing countries. The objective of this study was to evaluate the beef and lamb meat quality from supermarkets and shops in summer and winter season. Beef and lamb meat were stored at 4±1 o C during 5 days and test for microbiological properties, oxidation stability, and color properties, in beef and lamb meat. Samples were collected from...

PURPOSE The aim of this work was an evaluation of the influence of physical exercise in high-altitude conditions (about 2000 m above sea level) on thiobarbituric acid reactive substances (TBARS) and superoxide dismutase (SOD) and catalase (CAT) activities in 10 kayakers and 10 rowers. METHODS During their training, the sportsmen performed different kinds of static and dynamic efforts. The blo...
