In order to investigate the influence of fatty acid pattern and antioxidants other than vitamin E on lipid peroxidation and antioxidant levels of plasma very low density and low density lipoproteins (VLDL + LDL), the effects of three diets (equalized for vitamin E) containing soybean oil, olive oil, or an oleate-rich mixture of triglycerides (triolein) were studied in rats. A significantly lowe...

The present study examined the effects of chitosan (Ch) and chitosan combined with sodium tripolyphosphate (Nch) nanoparticles as coating materials for Cynoglossus arel fillets during superchilling storage. Treatments included the following: C (untreated, control samples), AC (treated with 1% glacial acetic acid, acid control), Ch (treated with 2% w/v chitosan solution, Chitosan) and Nch (treat...

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...

The impairment of synthesis in vitro of ascorbic acid by liver extracts from animals deprived of vitamin E (1, 2) is due to the inhibition of the enzyme(s) located in the microsomes (3) which catalyzes the oxidation of n-gulonolactone to L-ascorbic acid. This enzyme or enzymic complex will be termed gulonolactone oxidase. Concurrent with the inhibition of gulonolactone oxidase, a material is fo...

Serum concentration of thiobarbituric acid (TBA) reactants in the hepatic vein were measured before and after transient dearterialization of the liver in five human subjects bearing unresectable hepatocellular carcinoma (HCC). During 1 hour of the occlusion of the hepatic artery, change in TBA reactants level was slight. However, the mean value of TBA reactants in 1 hour after the reflow increa...

OBJECTIVE In order to utilize fat from broiler byproducts efficiently, it is necessary to develop an appropriate rendering procedure and establish quality information for the rendered fat. A study was therefore undertaken to evaluate the influence of rendering methods on the amounts and general properties of the fat recovered from broiler skin. METHODS The yield and quality of the broiler ski...

abstract in this study, big-head carp flesh was processed and fish finger was produced by the formula of 1, 2 and 3 with 70, 80 and 93.5 percent of big head fish flesh respectively. then sensory attributes, biochemical changes and nutritional value such as peroxide value (pv), thiobarbituric acid (tba) and the total volatile nitrogen (tvb-n) changes and microbial load of all three formulas were...

Two non colored and one colored rice varieties from Minahasa Regency, North Sulawesi, Indonesia were analyzed to determine the phytochemicals and antioxidant properties as natural antioxidant sources. Different brans of rice varieties divided into two groups: red rice and non colored (Superwin and Cigeulis) were macerated by ethanol (70%) and extracted with organic solvents (butanol, ethyl acet...

Synthesis of 5-arylidine thiobarbituric acids containing different functional groups with variable electronic characters were described and their Co(2+), Ni(2+) and Cu(2+) complexes. The stereochemistry and mode of bonding of 5-(substituted benzylidine)-2-TBA complexes were achieved based on elemental analysis, spectral (UV-VIS, IR, (1)H NMR, MS), magnetic susceptibility and conductivity measur...
