Background & Aim: When the level of free radicals is increased and also when both the enzymatic systems and low molecular antioxidants are not sufficient to protect the organism, it seems necessary to get antioxidants from external sources. This study aimed to evaluate the antioxidant potential of different parts of Catharantus roseus Experimental: The antioxidant potential of ethanol...

Abstract. The search for new strategies the correction of exogenous toxic liver lesions is due to steady increase in incidence hepatitis and cirrhosis among working population, which an important medical social problem.

In this study,the quality characteristics which include(physicochemical,structural and sensory evaluation)of beef loin submitted to fast freezing thawed by five different methods (Refrigerator,Oven,Microwave,tap water Room temperature)were examined The samples were defrosted the point of reaching a core temperature 0oC,followed several parameters include physical characteristics[(drip loss,thaw...

The effect of frozen storage on lipid peroxidation in Atlantic mackerel (Scomber scombrus) stored for up to 26 weeks at -10 or -80°C (control), with and without green tea antioxidants, was investigated. Hydroperoxides (PV) and aldehydes (TBARS) were measured by HPLC and LC-MS and hexanal by GC. There was an increase in peroxide value which was associated with an increase in aldehydes, followed ...

Pleurotus eous is an edible oyster mushroom currently available in Southern part of India. There is no information about the antioxidant and therapeutic properties of this mushroom. Pleurotus eous aqueous extract (PEAE) were prepared and analysed for their antioxidant activity by in vitro assays such as DPPH, hydroxyl radicals, Ferric Thiocyanate (FTC) and Thiobarbituric acid (TBA) test. The ne...

BACKGROUND Reactive oxygen species and particularly free radical induced lipid peroxidative tissue damage have been implicated in the pathogenesis of various renal diseases. Lipid peroxidation is assessed indirectly by the measurement of secondary products, such as malondialdehyde (MDA), using the widely employed thiobarbituric acid reactive substances (TBARS) method. However, this method lacks...

The quality and nutritional value for both fish protein concentrate (FPC) made from tilapia by-products as well as salt-biscuits supplemented with 5% FPC were evaluated. The resultant product (FPC) was composed (on wet weight) of 4.18% moisture, 68.83% protein content, 0.75% lipid and 25.39% ash and it was more uniform in color and texture. In addition, the pH value was 6.67 and total volatile ...

Oxidative damage and antioxidant properties were studied in Mugil cephalus exposed to cadmium, copper, lead and zinc in chronic toxicity test as pollution biomarkers. The elevated thiobarbituric acid reactive substances (TBA-RS) levels observed under exposure to heavy metals, leading to the oxidative damage resulting in lipid peroxidation (LPX). Increased activities of antioxidants, catalase (C...

fish finger is a semi-prepared product of fish that many studies have been done to improve its texture, taste, flavor and color. the present study aims at investigating the quality and sensory characteristics of fish fingers produced from fillet and surimi of common carp during storage in refrigerator. fish fingers were packed and then stored in refrigerator (4 °c). chemical parameters (fat con...

Urinary lipoperoxides, measured as the malondialdehyde-thiobarbituric acid adduct, were quantified by adapting to urine the liquid-chromatographic method of Wong et al. (Clin Chem 1987;33:214-20) to plasma. Reference intervals for untimed urine specimens from 121 men, ages 16 to 67 years, and 107 women, ages 15 to 55, were determined. Their concentrations differed significantly (P = 0.015), mal...
