INTRODUCTION Bronchial asthma is a complex disease in which genetic factors, environmental factors and oxidative damage are responsible for the initiation and modulation of disease progression. If antioxidant mechanisms fail, reactive oxygen species damage the biomolecules followed by progression of the disease. Catalase is one of the most important endogenous enzymatic antioxidants. In the pre...

In this paper, we report the synthesis and biological evaluation of picolylamide-based diselenides with the aim of developing a new series of diselenides with O···Se non-bonded interactions. The synthesis of diselenides was performed by a simple and efficient synthetic route. All the products were obtained in good yields and their structures were determined by 1H-NMR, 13C-NMR and HRMS. All thes...

Tall fescue (Festuca arundinacea Schreb.) is an important cool season forage plant that is not well suited to extreme heat, salts, or heavy metals. To develop transgenic tall fescue plants with enhanced tolerance to abiotic stress, we introduced an alfalfa Hsp23 gene expression vector construct through Agrobacterium-mediated transformation. Integration and expression of the transgene were confi...

the present study was carried out to examine the effects of satureja khuzistanica essential oils(skeo), on cholesterol content, fatty acids composition, and thiobarbituric acid reactive substances,(tbars) concentration of raw breast meat in broiler chickens. a total of 720 one-day-old broilerchicks (cobb 500) were taken as sample to study the effects of six experimental treatments in 6replicate...

Interaction between carcass quality grade and end-point cooking temperature on eating quality of Hanwoo m. longissimus was investigated. Ten (10) of steers were sampled from a commercial population; carcasses with QG 1(++) (n=5) and QG 1 (n=5) were chosen. Samples were cooked by electric oven at 60 or 82℃ and compared with uncooked control samples. The pH was not affected by cooking temperature...

The present study showed that exposure of chlorpyrifos, O,O'-diethyl-O-3,5,6-trichloro-2-pyridyl phosphorothionate (CPF), a widely used pesticide in rats caused significant inhibition of acetylcholinesterase (AChE) activity in different tissues viz., liver, kidney and spleen. CPF exposure also generated oxidative stress in the body, as evidenced by increase in thiobarbituric acid reactive subst...

The effect of storage temperature (65°C, 48 hours) on the oxidative stability of a food-grade water-in-oil-in-water (W/O/W) emulsion was studied by comparison with an oil-in-water (O/W) emulsion. The emulsions were prepared with linseed oil or olive oil, and in each case, two antioxidants were evaluated, an aqueous Melissa lyophilized extract and BHA. Emulsions were characterized using brightfi...

In this study, we measured free radicals and thiobarbituric acid-reactive substances (TBARS) in hepatocellular carcinoma and in non-cancerous liver parenchyma. There was a higher concentration of free radicals in malignant tissue than in non-cancerous tissue. In contrast, the level of TBARS was significantly (P < 0.01) lower than non-cancerous liver parenchyma. These paradoxical results suggest...

INTRODUCTION Thiobarbituric acid-reactive substance is a marker of oxidative stress and has cytotoxic and genotoxic actions. C- reactive protein is used to evaluate the acute phase of inflammatory response. OBJECTIVES To assess the thiobarbituric acid-reactive substance and C-reactive protein levels during extracorporeal circulation in patients submitted to cardiopulmonary bypass. METHODS T...

This research work aimed to enhance the concentration of some bioactive compounds in culantro (Eryngium foetidum L.) plantlets through gamma irradiation (0.0, 10.0, 20.0 and 40.0 Gy range) treatments. Gamma irradiation at 40.0 Gy significantly stimulated total phenolic, flavonoids, tannin and saponin contents. The effect of irradiation on antioxidant properties of culantro extracts was investig...
