BACKGROUND In IRCU it is uncertain whether variation of urinary protein, especially non-albumin protein (N-Alb-P), is due to the presence of stones or reflects alteration of oxidative metabolism. AIMS To validate in a tripartite cross-sectional study of 187 ambulatory male patients, undergoing a standardized laboratory programme, whether stones impact on N-Alb-P or the state of oxidative meta...

OBJECTIVE The purpose of this work was to investigate the relationship between the tumor volume and the endogenous selenium levels in untreated head and neck cancer patients. MATERIALS AND METHODS One hundred consecutive patients were included in this study. We measured the endogenous levels of selenium in the serum and the whole blood of all patients by atomic absorption spectrometry. Additi...

Abstract Objective: Globally, 3-5.2 percent of people suffer from diabetes which is one of the most serious metabolic disorders resulting in an increase in inflammatory biomarkers e.g. interleukin-6, tumor necrosis factor-alpha, and C-reactive protein. The aim of this study was to investigate the relationship between inflammation, oxidative stress and fasting blood glucose, lipid profile and a...

Light absorbed by colored intermediates of chlorophyll biosynthesis is not utilized in photosynthesis; instead, it is transferred to molecular oxygen, generating singlet oxygen ((1)O(2)). As there is no enzymatic detoxification mechanism available in plants to destroy (1)O(2), its generation should be minimized. We manipulated the concentration of a major chlorophyll biosynthetic intermediate i...

The current work investigated the ecotoxicological effects induced by Titanium Dioxide (TiO2) nanoparticles (NPs), used at three different concentrations (C1 = 10 ?g·L?1, C2 100 ?g·L?1 and C3 1000 ?g·L?1) in a laboratory experiment, on freshwater mussel Unio ravoisieri. Biochemical analyses of gills digestive glands revealed stress-related disruption antioxidant system. catalase activity rates ...

Scorpion envenomation is a main general health problem in developing countries, especially in tropical and subtropical regions. Hemiscorpius lepturus as a member of the Hemiscorpiidae family is cause of the most scorpion sting lethality in Iran. In the present study, the oxidative stress and antioxidant defense in serum of envenomated sheep with the venom of Hemiscorpius lepturus</...

Introduction: Lipid oxidation, including LDL oxidation, plays a pivotal role in development of atherosclerosis. Supplementing diet with antioxidants, such as vitamin E and walnut husk hydroalcoholic extract, may prevent LDL oxidation. In the present study, we investigated the in vitro effects of walnut husk hydroalcoholic extract on serum LDL oxidation caused by copper sulfate. Method: Blood sa...

Daily variation in circulatory melatonin level, during different seasons, has been reported to influence immune system and free-radical scavenging capacity in mammals, including human beings. Similar studies have not been carried out on small ruminant viz. goats that are susceptible to opportunistic infections, increased oxidative load and sickness during free-grazing activity and frequent expo...

The present study was conducted to examine the effects of L-carnitine on pulmonary hypertensive response in broiler chickens reared at high altitude and exposed to hypobaric hypoxia. A total of 192 day-old male broilers (Cobb 500) were randomly assigned to 4 treatments and 4 replicates of 12 chicks. A basal diet composed of mainly corn and soybean meal was formulated and served as a control. Th...
