Autoantibodies profile in autoimmune liver diseases and chronic viral hepatitis.

Despite their low prevalence, autoimmune liver diseases (AILD) cause liver cirrhosis, progress and leads to mortality from liver failure. Autoantibodies are confirmed to have significance in the early screening of AILD patients, especially in those who are asymptomatic before onset of clinical signs. This study aimed to assess levels of liver autoantibodies and their association with clinical manifestations of autoimmune liver diseases and chronic viral hepatitis (CVH) patients.

Mesenchymal stromal cell injection protects against oxidative stress in Escherichia coli-induced acute lung injury in mice.

Background Aims: Stem cells may be a promising therapy for acute respiratory distress syndrome. Recent in vivo and in vitro studies suggested that the mesenchymal stromal cells (MSCs) have anti-oxidative stress properties. We hypothesized that intravenous injection of bone marrow-derived mesenchymal stem cells (MSCs) could attenuate Escherichia coli-induced acute lung injury (ALI) in mice by controlling the oxidative stress status.

Interleukin-4 polymorphisms and response to combination therapy in Egyptian chronic hepatitis C patients.

In hepatitis C infection, the production of inappropriate cytokines levels may contribute to viral persistence and may affect the response to antiviral therapy. We investigate the effect of IL4 C-590T and C-33T polymorphisms on the response to combination therapy with interferon and ribavirin in chronic HCV patients. These single nucleotide polymorphisms were determined by PCR-RFLP in 235 responder and 210 non-responder to combination therapy.

Endothelial nitric oxide synthase gene polymorphisms and the risk of diabetic nephropathy in type 2 diabetes mellitus.

Endothelial dysfunction plays an important role in the pathogenesis of diabetic vascular disease, including diabetic nephropathy (DN). Endothelial nitric oxide synthase (eNOS) gene polymorphisms that affect eNOS activity are associated with endothelial dysfunction. The aim of this study was to evaluate the association of three polymorphisms of the eNOS gene (894G>T, -786T>C, and 27-bp-VNTR) with the risk of DN among type 2 diabetic patients.
