This study aimed to evaluate the composition, antioxidant capacity and antibacterial effects of Pistacia atlantica subsp. kurdica (baneh) essential oil on some important bacteria in food safety. Essential oil was derived using hydro-distillation method of the baneh fruits. Essential oil composition was determined using gas chromatography–mass spectrometry. The 2,2′-azinobis-(3...

Variations in phosphatidate phosphohydrolase (PAP) activity and triacylglycerol concentration were measured in pregnant and hormone-treated non-pregnant female rats. PAP activity in adipose tissue was elevated by 61% during pregnancy. The increase in the enzyme activity was paralleled with a rise in serum triacylglycerol concentration (44%). Estradiol injecting into non-pregnant rats increased ...

in this study the effects of fe2o3 and fe3o4 magnetic nanoparticles and edta on urease activity was investigated. the effect of nano-fe2o3 and nano-fe3o4 on urease activity were investigated. urease activity was studies by uv-vis spectrophotometry at 40 °c at ph = 7.2 using sodium phosphate as buffer. measurements were carried out using 0.075 mg/ml of urease and a range of nano-fe2o3 and nano-f...

Alpha-particle spectrometry is the most frequently used technique for the activity determination of alpha emitters, such as radium, uranium, plutonium, americium and thorium in environmental samples. In this paper an extensive uncertainty budget is presented for a typical alpha-particle spectrometry measurement of the Ra activity concentration in drinking water. The most influential parameters ...

effects of different carbon sources on growth and production of antifungal agent(s) by gymnopilus spectabilis were investigated. different carbon sources including; glucose, fructose, lactose, maltose, manitol and sucrose at the concentration of 10 g/l and slow releasing carbon sources including malt extract and soluble starch at the concentration of 2g/l were used. inhibition of spore germinat...
