The effects of dietary vitamin E levels on mucosal maltase and alkaline phosphatase (ALP) enzyme activities and on the amount of mucosal malonyldialdehyde (MDA) in broiler chickens were studied in the present study. One hundred and eighty of male day old broiler chicks (Ross 308 strain) were randomly assigned into five groups, each with three replicates and 12 chicks in each replicate. Chickens...

The development of an assay for the quantification of chicken immunoglobulin (IgY) and data evaluation is being demonstrated. An enzyme immunoassay was established to perform the quality control of IgY purifications from the egg yolk and to control IgY producing cells in vitro. Each step of the test procedure and possible alternatives were described. The assay was characterized by special test ...

In an attempt to gather objective evidence of possible hepato-cellular toxicity of the halogenated anaesthetics halothane and methoxyflurane pre-operative and post-operative enzyme estimations were done on patients admitted for elective operations. The series of approximately 500 cases included 160 patients submitted to cholecystectomy, an operation associated with a high percentage of detectab...

This article identifies a number of issues associated with current STEM education reform efforts, especially with regard to efforts to integrate engineering education into the K12 curriculum. Precollege engineering is especially problematic in STEM reform since there is no well-established tradition of engineering in the K12 curriculum. This discussion aims at identifying some of the issues and...

the activity of cytochrome p450 isozyme 3a4 (cyp3a4) enzyme and p-glycoprotein (p-gp) is modulated by grapefruit juice and herbal drugs. cyp3a4 is the major phase i drug metabolizing enzyme and p-gp is an atp-dependent drug efflux pump that regulates the intestinal absorption of orally administered drugs. honey is commonly consumed as a dietary supplement. however, its influence on human cyp3a4...

A study was conducted to evaluate the effects of varying drying temperature (Fresh, 85, 95 or 105 degrees C) on the nutritive value of maize and response of broiler chickens to diets based on such grain, and supplemented with a microbial enzyme (Avizyme 1500). The chemical composition of the grain was affected by drying temperature. Starch and amylopectin contents were increased while there was...

BACKGROUND/OBJECTIVES Ultraviolet B (UVB) irradiation on skin can induce production of reactive oxygen species (ROS), which cause expression of matrix metalloproteinases (MMPs) and collagen degradation. Thus, chronic exposure of skin to UVB irradiation leads to histological changes consistent with aging, such as wrinkling, abnormal pigmentation, and loss of elasticity. We investigated the prote...
