[ 1 ] - Quantification Analysis of Dot Blot Assays for Human Immunodeficiency Virus Type 1 and 2 Antibodies

Objective Dot Blot (DB) assay provides highly specific results, but usually not reliable for quantification of antibody production. The need for a more objective DB assay to provide a better definition of the immune status, against HIV antigens, promoted this study to be done to develop a quantitative DB assay. Material and Methods Dot blot (DB) strips for antibodies directed to human immuno...

[ 2 ] - راه‌اندازی و به‌کارگیری روش الیزا به‌منظور تشخیص حضور آنتی‌ژن p24 در خون افراد آلوده به HIV

Introduction: Human immunodeficiency virus is the etiologic agent of immune system deficiency and the infected patients are susceptible to opportunistic infections and AIDS. Transmission of infection during blood transfusion and diagnosis of infection in hospitals and public health settings have steadily been a worldwide concern. Different techniques are now available for the diagnosis of HIV i...

[ 3 ] - راه‌اندازی روش RT-Nested PCR به منظور تشخیص ویروس نقص ایمنی اکتسابی تیپ یک

  چکید ه   سابقه و هدف   ویروس نقص ایمنی اکتسابی تیپ یک( HIV-1 ) عامل ایجاد کننده سندرم نقص ایمنی اکتسابی انسانی”ایدز” می‌باشد. انتقال بیماری از طریق انتقال خون در دوره پنجره، در مراکز انتقال خون یک معضل جهانی محسوب می‌شود. علاوه بر این، نیاز مبرمی برای تشخیص سریع، حساس و دقیق عفونت HIV-1 قبل از ظهور آنتی‌بادی در بدن فرد آلوده در بیمارستان‌ها و مراکز بهداشتی احساس می‌شود. تشخیص ژنوم ویروس HIV-1...

[ 4 ] - Evaluation of IL-17 and IL-10 Production in Infectious Mononucleosis in EBV Patients

Epstein–Barr virus is primarily the cause of acute infectious mononucleosis and can also cause lymphoma and autoimmune diseases. Th17 cells, which are a unique subset of ThCD4+ cells, direct the infection toward inflammation through production of inflammatory cytokine IL-17. In contrast, Treg Foxp3 cells inhibit inflammation through secretion of anti-inflammatory cytokine IL-10, leading to chro...

[ 5 ] - Effects of hepatitis C virus NS3 protein on expression of heat shock protein 70 and Glypican3 as the markers of hepatocellular carcinoma

Background and Aims: Hepatitis C virus (HCV) infection is an important risk factor for the development of liver cancer. The HCV NS3 protein plays a key role in the virus life cycle and can affect normal cellular activities, such as cell proliferation, cell death, and cell signaling pathways. Moreover, it may influence malignancy development. Two cellular genes, heat shock protein 70 (HSP70) and...
