background: the modern dairy cows, due to intensive selection for higher milk production during past decades, have become more resistant to insulin. accompanied with dmi depression in per parturient dairy cow, insulin resistance may lead to a massive release of non-esterified fatty acids (nefa) to bloodstream which might act as a start point for development of other diseases. objectives: the pu...
Functionally hepatectomized rabbits showed convulsions and coma within 2 hours after the intravenous injection of fat emulsion and heparin. Intravenous injection of the detergent triton prevented this syndrome, if given before the fat emulsion and heparin, and reversed it if given subsequently. Extremely high plasma non-esterified fatty acid levels were noted in rabbits showing the convulsive s...
In contrast to UCP1, the primary function of UCP3 is not the dissipation of energy. Rather, several lines of evidence suggest that UCP3 is related to cellular long-chain fatty acid homeostasis. If long-chain fatty acids enter the mitochondrial matrix in their non-esterified form, they cannot be metabolized and may exert deleterious effects. To test the feasibility that UCP3 exports fatty acid a...
This study aimed to investigate the effects of insulin resistance (IR) during the close-up dry period on the metabolic status and performance of dairy cows as well as to determine the effects on body weight (BW) and metabolic status of their calves. An insulin tolerance test (ITT) was conducted by administering 0.05 IU/kg BW of insulin to 34 multiparous Holstein cows at 3 weeks prepartum. Blood...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
Triacylglycerols have the potential to supply significant fatty acids for ATP production by the myocardium, yet at present the exact contribution of triglyceridederived fatty acid to the energy economy of the myocardium is unresolved. Chylomicrons and very-low-density lipoproteins both add to energy production but the degree of provision may be related to particle size of individual lipoprotein...
The occurrence of a negative energy balance (NEB) and concurrent metabolic changes may be responsible for impaired reproductive performance. A characteristic metabolic feature of NEB is the mobilization of body fat, reflected in an increased plasma non-esterified fatty acids (NEFA) concentration. High plasma concentration of NEFA is reflected in elevated NEFA follicular concentrations. The aim ...
abstract this study aimed at investigating the possible relationship between self-assessment in writing and self-regulation of iranian efl learners. the main purpose of the study was not only to report and inform about this relationship, but also to investigate and find practical outcomes of the incorporation of self-assessment in writing, such as improving writing skill. the research was carr...
