the aim of this study was to evaluate the effects of three lighting programs on immune system and performance of broiler chickens. a total of 288 seven day-old male broiler chicks (ross-308) were randomly distributed between three treatments. each group was housed in the separated room with eight pen and 12-birds per pen. the management conditions were similar for all treatments throughout the ...

Z-scan technique is an effective tool for measuring the optical nonlinearity of the materials. By using this technique the measurement was made for total protein and albumin. The nonlinear refractive index of the total protein and albumin were found to vary linearly with concentration. Hence by calculating the nonlinear refractive index it is possible to measure their concentration in the sampl...

Twenty isolates of Trichoderma harzianum wereisolated from the rhizosphere of healthy pistachio plants from different localities of Kerman Province, Iran.Five isolates with high antagonistic activity in in vitro assays against Verticillium dahliae (the causal agent of pistachio wilt), were investigated for their effect on the defense enzymes, peroxidase (PO), phenyl alanine-ammonia lyase (PAL) ...

Introduction: Increased oxidative stress is widely accepted to be a factor in the development and progression of Alzheimer’s disease. Triazine derivatives possess a wide range of pharmacological activities including anti-oxidative and anti-in.ammatory actions. In this study, we aimed to investigate the possible protective effect of 3-thioethyl-5,6-dimethoxyphenyl-1,2,4-triazine (TEDMT) on H2O2-...

  Background:The dynamic binding capacity (DBC) of a chromatography matrix in protein purification is the amount of the total protein absorbed into the matrix, before occurrence of a significant break in the breakthrough curve. Optimization of the process criteria for maximum DBC avoids extra process scale-up and reduces ...

Background: Camel and sheep have high disperse and tolerance in tropical regions. But different results of harsh condition tolerance ability of them have been reported. ObjectiveS: The objective of this study was to determine the heat stress tolerance in camel and sheep by evaluating changes in blood serum metabolites and to report and compare the serum biochemical profile of sheep and camel du...

Proteins in living organisms express various important functions by interacting with other proteins and molecules. Therefore, many efforts have been made to investigate and predict protein-protein interactions (PPIs). Analysis of strengths of PPIs is also important because such strengths are involved in functionality of proteins. In this paper, we propose several feature space mappings from pro...

introduction: laryngectomy in patients with laryngeal cancer can lead to the reduction of nutritional parameters. supportive treatments and supplementary nutritional supports are recommended in all patients undergoing laryngectomy, even with acceptable preoperative nutritional indices.the aim of this study was to evaluate postoperative changes in nutritional parameters in patients with laryngea...
