EFFECT OFBETAINE  LEVELS ON BROILER PERFORMANCE  UNDER CYCLIC HEAT STRESS
ABSTRACT: This study was carried out at the Research Poultry Farm, Faculty of Agriculture, Sohag University,Egypt. It was designed to study the effect of betaine supplementation on broilers performance under cyclic heat stress. A total number of 375 Ross, one day-old were equally divided into five groups (75 birds/group) with three replicates (25birds / replicat). In the first group, birds ... Read more

Prophylactic and Ameliorative Effect of 𝑁-Acetylcysteine on Doxorubicin-Induced Neurotoxicity in Wister Rats
Doxorubicin (DOX) is an anthracycline antibiotic and a quinone-containing chemotherapeutic drug used for various types of cancers. However, as with most anticancer drugs, it causes many toxic effects, one of them is cognitive impairment. The present study investigated the prophylactic and ameliorative effect of n-acetylcysteine (NAC) against DOXinduced neurotoxicity in rats. Rats were divided into four groups. Control group: rats ...

Design, Synthesis and Biological Evaluation of New HDAC1 and HDAC2 Inhibitors Endowed with Ligustrazine as a Novel Cap Moiety
INTRODUCTION: Histone deacetylases (HDACs) represent one of the most validated cancer targets. The inhibition of HDACs has been proven to be a successful strategy for the development of novel anticancer candidates. METHODS: This work describes design and synthesis of a new set of HDAC inhibitors ( 7A-C and 8A, B) utilizing ligustrazine as a novel cap moiety, and achieving the ... Read more

Near UV-irradiation of CuOx-impregnated TiO2 providing active species for H2 production through methanol photoreforming
Copper doped‐TiO2 (P25) nanomaterials have been intensively studied as promising catalysts for H2 production by photo‐reforming of selected organic compounds. However, the role of copper oxidation states on the improvement of photocatalytic activity is still debated. In this work, CuOx‐impregnated P25‐TiO2 catalysts were used for photocatalytic production of hydrogen from methanol. Copper species/oxidation states both in the as‐prepared catalysts and ...

Prevalence of Tissue Parasites in Cattle and Buffaloes Slaughtered in El-Minia Governorate Abattoirs, Egypt
Abstract: The present study was conducted to determine the prevalence of meat borne parasitic infection in 170 animals (120 cattle and 50 buffaloes) slaughtered in El-Minia Governorate abattoirs, during the period from June 2017 to May 2018. The obtained data were statistically analysed by SPSS software using ANOVA test at 95 % confidence level (P ≤ 0.05). The study revealed ... Read more

Urinary Screening for Detection of Renal Abnormalities in Asymptomatic School Children, Sohag Governorate, Egypt
Background: Dipstick urine analysis is the most common method for screening children for detecting urinary abnormalities. This study is aimed to estimate the frequency of urinary problems among children aged 6-13 years from five primary schools in different parts of the Sohag Governorate, Egypt. Study Design and Setting: Cross-sectional study carried out by the Pediatrics Department and Community Medicine Departments ... Read more
