this study investigated the fatty acids profile, oxidative stability indices, and bioactive compounds of virgin and processed olive oils (leccino and frantoio cultivars). results showed that fatty acid profile of the studied oils contained mostly oleic acid followed by palmitic and linoleic acid. acid values of virgin frantoio and processed leccino were 0.78 and 0.18 mg koh/g oil, with peroxide...

The ability of the conceptus to respond to genotoxic stress may be critical for normal development, particularly after exposure to genotoxic teratogens. Members of the phosphatidylinositol 3-kinase (PI3K) superfamily are involved in controlling cell cycle activity and maintaining genomic stability. The expression of PI3K family members ATM, ATR, and DNA-PKcs, and downstream genes p53, GADD45, a...

effect of methanolic leaf extract of moringa oleifera for the stabilization of butter oil with modified fatty acid profile at ambient temperature was investigated. twelve sahiwal cows of first and early lactation were randomly stratified into two groups in a completely randomized design and fatty acid profile of milk fat was modified by feeding 300 grams calcium salts of fatty acids (per cow pe...

The ontogeny of endothermy in birds is associated with disproportionate growth of thermogenic organs and increased mitochondrial oxidative capacity. However, no similar study has been made of the development of these traits in ectotherms. For comparison, we therefore investigated the metabolism, growth and muscle mitochondrial function in hatchlings of a turtle and a crocodilian, two ectotherms...

Hens were immunized on thighs by using whole cells of Streptococcus mutans MT8148 serotype c strain as antigen through intramuscular (im) and subcutaneous (sc) routes to investigate the difference of immunization reactions and the changes in yolk antibody activities against antigen after initial immunization. Several properties of crude IgY were examined to evaluate the stability during food pr...

In most animals, longevity is achieved at the expense of fertility, but queen honey bees do not show this tradeoff. Queens are both long-lived and fertile, whereas workers, derived from the same genome, are both relatively short-lived and normally sterile. It has been suggested, on the basis of results from workers, that vitellogenin (Vg), best known as a yolk protein synthesized in the abdomin...

The purpose of the current study was to detect effects different levels rosemary volatile oil (VO) supplemented laying quail diets on performance, egg quality parameters, and yolk oxidative stability. In this study, a total 105 quails (Coturnix coturnix Pharaoh) at age 6 weeks were used 3 main groups formed, each containing 35 quails. Also, group separated into 5 replicates an equal number Quai...

The transcription factor activator protein-1 (AP-1), composed of the Fos and Jun families of proto-oncogenes, is induced in response to extracellular signals as part of an immediate-early gene response. We hypothesize that teratogens such as oxidative stress induce AP-1 activity in the rat conceptus and that this AP-1 response may either trigger abnormal development or protect the embryo agains...
