Lipid peroxidation induced by reactive oxygen species (ROS) is involved in the pathogenesis of malignancy. Overall, lipid peroxidation levels are indicated by malondialdehyde (MDA), which is the most frequently used biomarker to detect oxidative changes. Antioxidant defense systems such as glutathione (GSH) limit cell injury induced by ROS. Therefore, MDA and GSH can be used to monitor oxidativ...
background: oxidative stress in reproductive system leads to sperm dna damage and sperm membrane lipid peroxidation and may play an important role in the pathogenesis of male infertility, especially in idiopathic cases. antioxidants such as carotenoids function against free radical damages. objective : the aim of this study was to determine the levels of lycopene, beta-carotene and retinol in s...
Background and purpose: Copper is a trace element that is used in various industries. Copper nano-particles are being used in different skin care products, lubricants, oils, polymers, metal covers, plastics, inks, etc. Previous studies have shown that both copper sulfate and copper nano-particles can induce cellular genotoxicity and DNA damage. So, this study aimed at evaluating and comparing g...
Background and purpose: Gentamicin, an aminoglycoside antibiotic, is used in treatment of Gram-negative infections. However, its usefulness is restricted by its nephrotoxicity. The present study aimed to evaluate the potential protective effects of mummy and Vit E against gentamicin-induced nephrotoxicity in rats. Materials and methods: In this experimental study, 36 adult albino Wistar rats...
In individuals with sickle cell disease, a variable number of irreversibly sickled cells (ISC) is present that may contribute to the pathophysiology of sickle cell anemia. The present study was undertaken to determine the possible role of membrane lipid peroxidation in the genesis of ISC. After 24 hr of simple aerobic incubation, sickle cells accumulated 2-3 times more malonyldialdehyde (MDA), ...
Background and Aim: Oxidative stress is reported to be the cause of many diseases, especially in the obese. Recently, the use of herbal supplements, particularly polyphenols – has been emphasized to prevent the formation of free radicals. Thus, the present study was performed to determine the effect of long-term pomegranate supplementation and aerobic training on total antioxidant activity and ...
Introduction : Oxidative stress is considered as one of the factors that can damage tissues . The aim of this study was to investigate the effect of short term dark chocolate supplementation pre-incremental exercise on vascular lipid peroxidation in active young girls. Methods : This is a semi-experimental study. 16 active girls in two groups of experimental (dark chocolate supplementation)...
OBJECTIVE To see whether there was a link between blood transfusion and lipid peroxidation as measured by urinary malondialdehyde (MDA) concentration in preterm infants. METHODS Urine samples were collected before and after blood transfusions in preterm infants. Twenty blood transfusion episodes were studied in 12 infants (some infants were studied on more than one occasion). Twenty two infan...
The effects of Di (2-Ethylhexyl) Phthalate (DEHP) exposure on lipid peroxidation and antioxidant levels in blood samples rats were investigated. Forty female Wistar-Albino weighing 250-300 g used for the study. divided into 5 groups; group 1: control group, 2: positive (corn oil-based diet), 3: 20 mg DEHP per kg body weight (bw) (lowest dose tested), 4: 100 kg/bw (medium 5: 500 (highest tested)...
Background and Objective: Diabetes as one of the most prevalent and chronic diseases is dramatically increasing worldwide and Iran is no exception. Diabetes mellitus with oxidative stress and overproduction of reactive oxygen species (ROS) can cause metabolic disorders and deactivate the antioxidant defense. Palmatine hydrochloride has anti-diabetic and antioxidant effects among its various pha...
