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 ...

In-vitro evaluation of Nigella sativa and Punica granatum effect on protoscolices of hydatid cysts
Cystic echinococcosis (CE) are commonly found in the liver and lungs of affected hosts. The treatment approach is usually surgical, or giving drugs in conjunction before surgery to kill protoscolices, to avoid anaphylactic shock from leakage of hydatid fluid into the peritoneum and to decrease opportunities for recurrences. The present study was to evaluate the in-vitro scolicidal efficacy of hydroalcoholic ... Read more

Molecular phylogenetic analysis of Cysticercus ovis from Egypt based on MT-CO1 gene sequences
Cysticercus ovis or sheep measles is the larval stage of Taenia ovis, which is the intestinal tapeworm of dogs. It is found in the cardiac and skeletal muscles of sheep and can be the cause of partial or total condemnation of carcasses at abattoirs. The aim of the current work was to determine the prevalence of C. ovis among sheep ... Read more

Fully-Quadrature Spatial Modulation over Rician Fading Channels
Space modulation techniques (SMTs) are promising multiple-input multiple-output (MIMO) schemes that draw an intriguing attention lately due to their superior performance enhancement in terms of energy efficiency, spectral efficiency, and unpretentious receiver's complexity. In the SMTs, the indices of the building blocks of the communication system are harnessed in an innovative way to embed an additional information. As such, the ... Read more

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
