INTRODUCTION Type 2 diabetes mellitus (T2DM) is associated with increased production of reactive oxygen species and a reduction in antioxidant defenses leading to oxidative stress. Glutathione S-transferases (GSTs) modulate oxidative stress. The present cross-sectional study was aimed at investigating the association between the GSTP1 gene polymorphism and(More)
Hepatocellular carcinoma (HCC) is one of the most aggressive cancers worldwide. In Egypt, the disease is usually detected in an advanced stage at which no treatment may be effective including surgery. Early detection of the disease is thus an important goal allowing the patient to be treated before the enlargement of the tumor or its metastasis to distant(More)
Hepatitis C virus (HCV) genome contains two envelope proteins (E1 and E2) responsible for the virus entry into the cell. There is a substantial lack of sequences covering the full length of E1/E2 region for genotype 4. Our study aims at providing new sequences as well as characterizing the genetic divergence of the E1/E2 region of HCV 4a using our new(More)
INTRODUCTION We studied the frequencies of the 3' and 5'-end vitamin D receptor (VDR) gene polymorphisms and their correlation with bone mineral density (BMD) in Egyptian pediatric acute lymphoblastic leukemia (ALL) patients receiving calcium and vitamin D supplements. The purpose of this study is to find out the relation between VDR polymorphism and the(More)
INTRODUCTION In our efforts to study the dimensions affecting the electronic service quality (eSQ) measurement in the Business to Business (B2B) domain, we were faced with a problem of the lack of consensus on the Business to Consumer (B2C) eSQ measurement dimensions, which makes it difficult for researchers in this field to generalize their findings on the(More)
In 2011-2012, sixty nine samples were collected from alfalfa plants showing viral infection symptoms in Riyadh region. Mechanical inoculation with sap prepared from two collected samples out of twenty five possitive for Alfalfa mosaic virus (AMV) by ELISA were produced systemic mosaic on Vigna unguiculata and Nicotiana tabacum, local lesion on Chenopodium(More)
