About 25 yo of the total cellular invertase and trehalase activity were found in a purified Neurospora wall preparation. Attempts were made to dissociate these enzymes from the walls with chemical reagents and hydrolytic enzymes. A detergent (Triton X-IOO), a sulphydryl reducing agent (P-mercaptoethanol), a chelating agent (ethylenediaminetetraacetate), a concentrated salt solution (I M-KCl), a...

this study was conducted to evaluate production response of early lactating cows to rumen protected fats. twelve (nine multiparous and three primiparous) holstein cows (26±4 d in milk) were empolyed in a replicated 3×3 latin square design of 21-d periods. each period consisted of 14 days of adaptation and 7 days of sampling. cows received diets containing either one of two types of protected fa...

abstract efficient use and management of organic matter are important aspects of sustainable agricultural. organic matter is relatively low in majority of soils in iran, and continuous use of n fertilizer would create environmental hazards. therefore, the combined use of n fertilizer and organic wastes is an effective strategy. the purpose of this study was investigating of residual effects of ...

Serum agglutinins of chick and pigeon cells are predominantly immunoglobulin M and can be inactivated by 2 mercaptoethanol. 2 Mercaptoethanol is more effective than strong suspensions of red cells in removing the agglutinins of indicator cells from sera being prepared for HAI tests. In rubella HAI tests from a dilution of 1 to 10 dilute 2 mercaptoethanol offer a convenient method of removing ag...

Previous studies have clearly shown that the injection of iodized oil in the pregnant women may be a prophylactic strategy for IDD (Iodine Deficiency Disorders) and could improve the growth indices of their offsprings. Since the administration of pharmacological doses of iodine may occasionally lead to large goiter and rarely hypothyroidism, in the present study the thyroid function tests of th...
