Effect of mesenchymal stem cells and melatonin on experimentally induced peripheral nerve injury in rats.

Injury of a peripheral nerve (PNI) leads to both ischemic and inflammatory alterations. Sciatic nerve injury (SNI) represents the most widely used model for PNI. Mesenchymal stem cell-based therapy (MSCs) has convenient properties on PNI by stimulating the nerve regeneration.

Genotyping versus phenotyping of non-ABO erythrocyte antigens in patients with the Mediterranean hemopathic syndromes: Effect of transfusion therapy.

The Mediterranean hemopathic syndromes (MHS) are the most prevalent hemoglobinopathies in the Mediterranean basin. Transfusion therapy is the main therapy for these disorders, particularly for severe forms of the disease. Currently, pre-transfusion serological typing of erythrocyte antigens is the standard tool for reducing complications of transfusion in those patients.

Clinicopathological Significance of CD133 and ALDH1 Cancer Stem Cell Marker Expression in Invasive Ductal Breast Carcinoma.

Background: Biomarkers in breast neoplasms provide invaluable information regarding prognosis and help determining the optimal treatment. We investigated the possible correlation between cancer stem cell (CSC) markers (CD133, and ALDH1) in invasive ductal breast carcinomas with some clinicopathological parameters.

Aim: To assess the correlation between expression of cancer stem cell (CSC) markers (CD133, and ALDH1) and clinicopathological parameters of invasive ductal breast carcinomas.

Antiparasitic activity of cystine protease inhibitor E-64 against Giardia lamblia excystation in vitro and in vivo.

In this work, the therapeutic effect of E-64, a broad spectrum cystine protease inhibitor against Giardia lamblia excystation was studied in vitro and in vivo. Purification of cysts from heavily infected human faecal samples followed by excystation and axenic cultivation of the emerging trophozoites in TYI-S-33 medium were done. In vivo, the response was evaluated experimentally through counting oocysts out-put every other day until the infection eradicated from the stools of infected E-64 treated mice compared to untreated.

Infectivity of Trichomonas vaginalis pseudocysts inoculated intra-vaginally in mice.

In addition to the trophozoite, pseudocyst is another morphological form which is recently identified among genitourinary trichomonads. Although, this pseudocyst is competent to divide, its role in Trichomonas life cycle has not yet been confirmed. In this study the ability of intra-vaginally inoculated T.

Pathophysiological variability of different genotypes of human Blastocystis hominis Egyptian isolates in experimentally infected rats.

The genotyping of Blastocystis hominis clinical isolates obtained from 28 gastrointestinal symptomatic patients and 16 asymptomatic individuals were identified by polymerase chain reaction using sequenced-tagged site (STS) primers. Then, pathophysiological variability between different B. hominis genotypes was evaluated in experimentally infected rats.

Uterine artery Doppler blood flow in cases of hydatidiform mole and its correlation with beta-hCG.

Objectives: To study the correlation between Doppler blood flow and beta-human chorionic gonadotropin (hCG), to assess the course of the disease and the follow up evaluation.

Setting: This study was conducted in Assiut University Hospital, Department of Obstetrics and Gynecology.

Design: Longitudinal study.
