Background: Despite setting the stringent criteria for the selection of safe donors, some human immunodeficiency virus (HIV)-positive volunteers manage to give blood. Considering the window period of screening tests, this could endanger the safety of blood supply.

Materials And Methods: A frequency match case-control study was conducted on HIV-positive and negative blood donors in Iran from 2007 to 2008.

In this work, the optical properties of Rhodamine B (RdB) are investigated in the attendance of various red blood cells (RBCs). RdB fluorophores, as biological markers, is excited using SHG-CW Nd:YAG laser at 532 nm. In fact, the addition of biomolecules of interest to the reference fluorophore notably changes the fluorescence properties of the suspension.

Since the traditional method generates biological waste, there is a significant demand for an easy, quick technique of blood type identification without contamination. In fact, individuals can be divided into four main blood groups whose antigens are available in red blood cell (RBC) membranes and the antibodies in the plasma. Here, UV-vis and photoluminescence (PL) spectroscopic methods are systematically used to find the spectra of blood typing antigens (A, B and AB) and antibodies i.

The oncogenic role of human cytomegalovirus (HCMV) has been recently shown in different cancers like colorectal cancer (CRC). According to the recent immunotherapy approach to target the CMV-expressing tumor cells, we investigated the CMV peptide-stimulated CD8+T cells functions in CRC patients compared to healthy individuals. All sixteen patients and seven controls were CMV seropositive.

Therapeutic Plasma Exchange in Tehran Between 2011 and 2014.

Ther Apher Dial

April 2020

Department of Biostatistics, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iran.

The goal of therapeutic plasma exchange (TPE) is to remove autoantibodies, pathogenic molecules, immune complexes, toxins, high concentration lipoproteins, and pathological proteins. We aimed to present the most common indication of TPE and rate of admission to the intensive care unit. From 2011 to 2014, our retrospective study was conducted including 1069 inpatients from the Tehran Blood Transfusion Center, which was responsible for performing therapeutic apheresis in all 122 hospitals of Tehran.

July 2014

2. Iranian Blood Transfusion Research Center & Tehran Blood Transfusion Center, Tehran, Iran ; 3. Dept. of Immunology, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iran.

Background: The aim of this study was to investigate the prevalence of hepatitis B, hepatitis C, HIV and syphilis infections in blood donors referred to Tehran Blood Transfusion Center (TBTC), and determine any association between blood groups and blood- borne infections between the years of 2005 and 2011.

Methods: This was a retrospective study conducted at TBTC. All of the donor serum samples were screened for HBV, HCV, HIV and syphilis by using third generation ELISA kits and RPR test.

Electronic address:

Hepatitis B envelope antigen (HBeAg)-negative hepatitis B virus (HBV) infection exerts both inactive carrier (IC) state and chronic hepatitis B (CHB), which are sometimes difficult to be differentiated. We aimed to assess the role of hepatitis B surface antigen (HBsAg) level in differentiation of CHB and IC among a group of chronic HBeAg-negative HBV-infected patients. A total of 251 HBeAg-negative HBV-infected patients were enrolled.

Background: Hepatitis B is a significant health problem and more than 350 million individuals are infected with hepatitis B virus (HBV) globally. About 5% of these individuals are coinfected with hepatitis D virus (HDV). HBV-HDV coinfection increases the rate of fulminant hepatitis, chronic hepatitis and cirrhosis.

Arch Iran Med

September 2014

Iranian Blood Transfusion Research Center and Tehran Blood Transfusion Center, Tehran, Iran Department of Immunology, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iran.

Background: Evaluating trends in blood donors' infectious diseases is essential for monitoring the safe supply of blood, donor screening effectiveness, and the occurrence of infections in the blood donor population which consequently gives an idea of the epidemiology of these diseases in the community. The aim of the present study was to assess the prevalence of hepatitis B, hepatitis C, HIV and syphilis by carrying out confirmatory tests in Tehran's blood transfusion center between 2005 and 2011.

Methods: This was a retrospective study conducted at Tehran's Blood Transfusion Center (TBTC) from 2005 to 2011.
