to estimate the optimum and effective amount of nitrogen fertilizer for quantity and quality improvement of three new durum wheat lines, this research was conducted in gachsaran dry-land agricultural research station for a duration of 4 years (2003-2007). the study was performed as a factorial expriment, using a randomized complete block design with 4 replications. two factors of: 4 nitrogen ra...

1. An enzyme produced by Aeromonas hydrophila and capable of lysing Staphylococcus aureus cells was purified 180-fold by gel filtration and chromatography on columns of AG-50 W resin. 2. Physical measurements on the purified enzyme suggest that it is a small basic protein with an isoelectric point between pH9.0 and pH9.5. 3. Maximum lytic activity was obtained in 20mm-tris-glycine buffer, pH8.5...

The MHC class II-associated invariant chain (Ii) is involved in the intracellular sorting of class II molecules to the endocytic pathway where peptides from processed exogenous antigens are bound, and thereby Ii is thought to enhance antigen presentation. Here we demonstrate that presentation of only one out of five epitopes of a given antigen is augmented by Ii. We have compared the presentati...

UNLABELLED Overactive Bladder Syndrome (OAB) is defined by the ICS (International Continence Society) as urinary urgency, with or without urgency incontinence and frequently associated with increase of frequency and nocturia. PURPOSE The aim of the study was to establish a correlation between OAB symptoms and Age in women aged 20-45. MATERIALS AND METHODS We interviewed 1050 women aged 20-4...

Three experiments of 28 days duration were conducted in three size groups (<1g, 1-5g and 5-10g) of Indian white shrimp, Fenneropenaeus indicus, to evaluate the appropriate protein: energy (GE) ratios in their diets. A common ingredient mixture consisting of fish meal, shrimp meal, ground nut oil cake, cholesterol, lecithin, vitamins and minerals blended with chicken egg albumin, tapioca flour a...

1. Whole-body protein turnover was measured in rats by constant infusion of 15N-labelled glycine, aspartate, valine and leucine and measuring the enrichment of hepatic and renal urea and ammonia nitrogen. 2. The values obtained with [15N]glycine were comparable with values reported with methods based on different assumptions. 3. [15N]Aspartate gave rise to an increased enrichment of urea and am...
