BACKGROUND: Berries are raising increasing interest in the last years because of their nutritional quality and the several bioactive compounds with antioxidant properties that contain. Many studies reported significant increases in the plasma antioxidant capacity after long term and acute consumptions of antioxidant-rich foods. OBJECTIVE: The aim of this work was to confirm the healthy effect o...

BACKGROUND Fructose-mediated protein glycation (fructation) has been linked to an increase in diabetic and cardiovascular complications due to over consumption of high-fructose containing diets in recent times. The objective of the present study is to evaluate the protective effect of (R)-α-lipoic acid (ALA) against fructose-induced myoglobin fructation and the formation of advanced glycation e...

The role of epidermal growth factor (EGF), a polypeptide containing 53 amino acids, on protection and repair of ethanol-induced gastric mucosal injury was investigated in rats. In addition, the effects of EGF on the gastric damage were evaluated histopathologically. We used 48 Spraque-Dawley rats which were divided into [corrected] three groups as control rats, ethanol treated rats and ethanol+...

The piperazine derivatives have been shown to inhibit human acetylcholinesterase. Virtual screening by molecular docking of piperazine derivatives 1-(1,4-benzodioxane-2-carbonyl) piperazine (K), 4-(4-methyl)-benzenesulfonyl-1-(1,4-benzodioxane-2-carbonyl) piperazine (S1), and 4-(4-chloro)-benzenesulfonyl-1-(1,4-benzodioxane-2-carbonyl) piperazine (S3) has been shown to bind at peripheral anioni...

Obesity causes many problems such as cardiovascular and chronic kidney diseases. The aim of this study was to evaluate the efficacy of retinoic acid and atorvastatin co-administration in kidneys protection against high-fat diet induced damage. Twenty-five male Wistar rats (200.00 ± 20.00 g) were divided into five groups: 1) Control (standard diet), 2) High-fat diet (cholesterol 1.00%, 75 days),...

The extraction and quantitation of carbonyl metabolites from cell lysate was accomplished using a carbonyl-reactive fluorous tag and capillary liquid chromatography coupled to mass spectrometry (capLC-MS). Selective fluorous tagging for ketones and aldehydes provided a 30-fold increase in sensitivity using electrospray ionization MS. Separation of fluorous tagged carbonyl resulted in good separ...

Gas-phase chemical behaviors of short-lived technetium carbonyl complexes were studied using a low temperature isothermal chromatograph (IC) coupled with a (252)Cf spontaneous fission (SF) source. Fission products recoiled from the (252)Cf SF source were thermalized in a mixed gas containing CO, and then technetium carbonyl complexes were formed from reactions between CO gas and various technet...

Carbonyl reductase catalyses the reduction of steroids, prostaglandins and a variety of xenobiotics. An unusual property of human and rat carbonyl reductases is that they undergo modification at lysine-239 by an autocatalytic process involving 2-oxocarboxylic acids, such as pyruvate and 2-oxoglutarate. Comparison of human carbonyl reductase with the pig enzyme, which does not undergo autocataly...

background stroke is the second cause of death and disability in the world, and oxidative stress which could be considered as a prognostic factor in patients for prevention, follow up and determination of stroke’s severity has a conceivable role in neural damage. objectives the aim of our study was to explain the association between oxidant/antioxidant imbalance as a prognostic factor in patien...
