Bovine spongiform encephalopathy (BSE) is a fatal infectious neurodegenerative disease in cattle, characterized by the accumulation of an abnormal, proteaseresistant prion protein (PrPSc) in the brain. BSE is similar to scrapie in sheep and goats and Creuzfeldt-Jakob disease in humans. Susceptibility in cattle hasbeen shown to be under the influence of two polymorphic locations, which are...

Background & Aims: Hepatitis C virus (HCV) infection is a leading cause of chronic liver disease worldwide. The clearance of the HCV is dependent on cytokines control led by genetic. The purpose of this study was to investigate the impact of Lymphotoxin (LT-A) polymorphism at +252 in susceptibility to chronic hepatitis C. Methods: In this case-control study, 120 individuals infected by HCV and ...

Introduction: CLL is one of the most common leukemias, which is categorized by the accumulation of mature CD5+ B-lymphocytes in the peripheral blood, bone marrow, and secondary lymphoid organs. In this study, the status of rs6449182 polymorphism of the CD38 gene and its association with clinical and laboratory parameters of CLL patients was evaluated. Methods: Genomic DNA extraction was perfor...

Background: Coronary artery disease (CAD) is a complex disorder. It thought to be result of gene-gene and gene-environment interactions. was reported that XbaI polymorphism ApoB gene associated with CAD. However, the results were conflicting risk factors not fully studied in previous studies. Aim: estimate association lipid profile, dietary pattern CAD Egyptian population. Subjects Methods: Thi...

macrophages and t-lymphocytes are involved in immune response to mycobacterium tuberculosis. macrophage produces interleukin (il)-1 as an inflammatory mediator. il-1 receptor antagonist (il1-ra) is a natural antagonist of il-1 receptors. in this study we aimed to examine the possible association between the variable number of tandem repeats (vntr) of the il-1 receptor antagonist (il1rn) gene an...

background: recurrent pregnancy loss (rpl) defined by two or more failed pregnancies before 20 weeks of gestation. several factors play a role in rpl including thrombophilic conditions which can be influenced by gene polymorphisms. plasminogen activator inhibitor-1 (pai-1) and angiotensin converting enzyme (ace) genes are closely related to fibrinolytic process, embryonic development and pregna...

background: vitiligo is an acquired skin disorder that selectively destroys melanocytes in epidermis with an unknown etiology.   objective: to investigate the exon 1 a49g polymorphism of cytotoxic t lymphocyte antigen-4 (ctla-4) gene in vitiligo patients.   methods: the a49g polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) method in 101 ...
