background: autoxidation is considered to be the main route of edible oil deterioration, which produces undesirable odors and flavors (attributed to primary and secondary products of unsaturated fatty acids) during storage and heating. objective: antioxidant activities of zataria multiflora (zmeo) and bunium persicum (bpeo) essential oils (eos) in linseed oil (containing higher ω-3 in vegetable...

the antioxidant activities of tbhq, bht and tocopherol mixtures at different concentrations (0, 100, 200, 400 mg/kg) have been evaluated by the application of differential scanning calorimetry (dsc) and rancimat apparatus. rancimat apparatus that measures the secondary oxidation products was set at 110 ⁰c with an air flow of 18-20 l/h to measure the induction period (ip) of the samples. the dsc...

Physiological agonists increase cytosolic free Ca2+ concentration to regulate a number of cellular processes. The platelet thrombin receptors, PAR (protease-activated receptor) 1 PAR-4 and GPIb-IX-V (glycoprotein Ib-IX-V) have been described as potential contributors of thrombin-induced platelet aggregation. Platelets present two separate Ca2+ stores, the DTS (dense tubular system) and acidic o...

Cytochrome P450 (CYP)2C9 and CYP2C19 are important human enzymes that metabolize therapeutic drugs, environmental chemicals, and physiologically important endogenous compounds. Initial studies using primary human hepatocytes showed induction of both the CYP2C9 and CYP2C19 genes by tertbutylhydroquinone (tBHQ). As a pro-oxidant, tBHQ regulates the expression of cytoprotective genes by activation...

The objective of this study was to work out different blends of oils amongst rice bran oil (RBO), soybean oil (SBO), and mustard oil (MO) to obtain a unique blend of oil having better shelf life. Further, in present work, the effect of synthetic antioxidant such as butylated-hydroxyanisol (BHA), butylhydroxyltoluene (BHT) and t-butyl-hydroxyquinone (TBHQ) were also evaluated by adding upto reco...
