Uterine histomorphological and immunohistochemical investigation during the follicular phase of estrous cycle in Saidi sheep.

Background: Saidi sheep are one of the most important farm animals in Upper Egypt, particularly in the Assiut governorate. Since they can provide meat, milk, fiber, and skins from low-quality roughages, sheep are among the most economically valuable animals bred for food in Egypt. Regarding breeding, relatively little is known about the Saidi breed.

Serological and histolomorphological investigation of camel bulls testes (Camelus dromedaries) during the rutting and non-rutting seasons.

Background: Camels are bred for their milk, meat, wool and hair, transportation, and their excrement as fuel. The seasonal reproduction of camel bull is accompanied by changes in sexual activity, the morphology, and function of the testes. This study aimed to evaluate the seasonal fluctuations in serum testosterone (T) levels as well as total antioxidant capacity (TAC) and malondialdehyde (MDA) levels in the testes of dromedary bulls (Camelus dromedarius) during the rutting and non-rutting seasons.

Histological, immunohistochemical and serological investigations of the ovary during follicular phase of estrous cycle in Saidi sheep.

Background: Saidi sheep are the most abundant ruminant livestock species in Upper Egypt, especially in the Assiut governorate. Sheep are one of the most abundant animals raised for food in Egypt. They can convert low-quality roughages into meat and milk in addition to producing fiber and hides therefore; great opportunity exists to enhance their reproduction.

Cognitive after-effects and associated correlates among post-illness COVID-19 survivors: a cross-sectional study, Egypt.

Background: COVID-19's after-effects among survivors are of increased concern. The cognitive aftermath of COVID-19 virus infection was underrated. This study aimed to identify and compare the cognitive impairment (CI) and its correlates among COVID-19 survivors and control subjects.

Circulating oxidative stress status in Bedouin she-camels (Camelus dromedarius) during the peripartum period.

This study aimed to assess the oxidative stress status in blood plasma of nomadic she-camels (Camelus dromedarius) during transition from late pregnancy to early lactation. From 12 late pregnant she-camels, blood was sampled weekly as they progressed from the third week prepartum up to the third week postpartum. Levels of albumin, uric acid, and malondialdehyde (a biomarker of lipid peroxidation) concentrations were fairly constant (P > 0.

Exploring the factors associated with coronaphobia among physicians during the COVID-19 outbreak in Egypt.

Background: Coronaphobia refers to intensified and persistent fears of contracting COVID-19 virus infection. This study aimed to evaluate the newly termed phenomenon, coronaphobia, and address its associated correlates among Egyptian physicians during the outbreak. A cross-sectional study, including a total of 426 Egyptian physicians working during COVID-19 outbreak, was conducted between March 1st and May 1st, 2020.

Opioid Use Disorders Attributed to Tramadol Among Egyptian University Students.

Background: Tramadol use is an overwhelming problem in Egypt with tremendous medical and social consequences especially among youth. Use liability among Egyptian university students is underevaluated. This study aimed to estimate the prevalence and associated correlates of tramadol use among students from Zagazig University, Egypt.

Cognitive Impairment and Tramadol Dependence.

Background And Objective: Cognitive impairment is one of the consequences of substance abuse. Tramadol abuse is a public health problem in Egypt. The objective of this study was to estimate the prevalence and correlates of cognitive impairment among tramadol-abuse patients and control subjects.

Protective role of propolis against reproductive toxicity of triphenyltin in male rabbits.

Triphenyltin (TPT) is known to cause endocrine disruption, reproductive toxicity and a decrease in testosterone production. It is involved in the production of reactive oxygen species. Propolis has been reported to be an important antioxidant.

Aluminium-induced deterioration in reproductive performance and seminal plasma biochemistry of male rabbits: protective role of ascorbic acid.

Aluminium (Al) has been proposed as an environmental factor that may contribute to some diseases, affect several enzymes and other biomolecules and induced free radical-mediated cytotoxicity. Also, Al induced reproductive toxicity and exerted a significant adverse effect on the steroidogenesis. The antioxidant ascorbic acid (AA) plays an important role in various physiological processes in the body including detoxification of different toxic materials.
