Determination of total fat, saturated fat, monounsaturated fat and trans fat content in food samples is necessary for complying with applicable food labeling requirements. A typical procedure for saponifi cation of the sample involves refl uxing with sodium methoxide in methanol, followed by a second refl ux with boron trifl uoride in order to esterify the free fatty acids. Prior to injection i...

this experiment was conducted to investigate the effects of different levels of oxidized fat (yellow grease) and copper sulfate on performance, carcass traits, blood metabolites and immune cells of broilers. this study was carried out as a 3 × 2 factorial experiment with 3 levels of oxidized fat (0, 2 and 4%) and 2 levels of copper sulfate (0 and 300 mg/kg) in 6 treatments, 3 replicates and 12 ...

purpose: obesity is one of the most common problems in the world. imbalance between energy consumption and expenditure is a main factor in weight disorder. exercise helps losing weight by increasing energy expenditure and modulation of the energy intake. the present study examined protective effects of daily moderate aerobic exercise on preventing weight gain in high fat diet rats. materials an...

in this study, the effect of addition of three different levels of microbial lipase (0, 4, and 8.0 g lipase in 100 kg milk) was investigated on the physiochemical properties, free fatty acids, textural properties, and microstructure of lighvan cheese during ripening. the addition of lipase did not significantly affect ph, acidity, moisture, and salt content of lighvan cheese, but increased its ...

despite a shortage of animal feed in iran, cereal stubble is often underutilized due to agro-economic reasons. on the other hand, lambs fed with a conventional fattening ration deposit a considerable amount of fat; therefore, this experiment was conducted aimed at better utilization of cereal stubble and reducing the fat content of lamb carcasses. fat-tailed mehraban and ghezel ram lambs were p...

there has been considerable inconsistency regarding the potential relationship between dyslipidemia and bone metabolism. the inflammatory stimulation through the receptor activator of the nuclear factor kappa-b ligand (rankl)/ receptor activator of the nuclear factor kappa-b (rank)/ osteoprotegerin (opg) pathway could be the infrastructural mechanism for hypercholesterolemia-induced bone loss. ...

lithium is widely used in medicine as an anti-depressive drug. in spite of abundant literature, questions on the side effects of lithium ions are far from being answered. in this study, the effects of lithium on biochemical parameters related to lipid metabolism were investigated. male wistar rats were treated with different doses of lithium for a period of up to 60 days. blood samples were col...
