[ 1 ] - Human cytomegalovirus infection in tumor specimens of Iranian patients with glioma

Human cytomegalovirus (HCMV) causes persistent infection in humans and severe diseases in fetus andimmunocompromised individuals. Although HCMV is not currently implicated in human cancer, emerging evidence suggests that HCMV infection might be specifically associated with some human malignancies including glioma. Glioma is one of the most common brain tumors affecting children and adults. In t...

[ 2 ] - Epidemiology of Rotavirus-Norovirus Co-Infection and Determination of Norovirus Genogrouping among Children with Acute Gastroenteritis in Tehran, Iran

Background: Enteric viruses, particularly human rotavirus and norovirus, have been shown to replace bacteria and parasites, as the most common pathogens responsible for acute diarrhea. However, there are still few epidemiological data on the simultaneous occurrence of these viruses in Iran. In this regard, the aim of this study was to assess the useful epidemiological data on the gastroenteriti...

[ 3 ] - Development of a Sensitive Quantitative Competitive PCR Assay for Detection of Human Cytomegalovirus DNA

Accurate and rapid diagnosis of human cytomegalovirus (HCMV) disease in immunocompromised patients has remained as a challenge. Quantitative competitive PCR (QC-PCR) methods for detection of HCMV in these individuals have improved the positive and negative predictive values of PCR for diagnosis of HCMV disease. In this study we used QC-PCR assay, using a co-amplified DNA standard, to quantitate...

[ 4 ] - Interferon Resistance of Hepatitis C Virus Genotypes 1a/1b: Relationship to Structural E2 Gene Quasispecies Mutations

Hepatitis C virus (HCV) envelope glycoprotein-2 (E2) inhibits the interferon (IFN)–induced, double –stranded RNA activated protein kinase (PKR) via PKR eukaryotic initiation factor-2α phosphorylation homology domain (PePHD). Present study examined the genetic variability of the PePHD in patients receiving interferon therapy. The PePHD region from HCV genotype 1a/1b infected patients receiving I...

[ 5 ] - Detection and Genotyping of Hepatitis D Virus from HBsAg Positive Patients in Iran Using RT-PCR

Hepatitis Delta virus (HDV) is a degenerate RNA virus or virusoid and a satellite of Hepatitis B virus (HBV). Three distinct genotypes are described for HDV; genotype I is distributed worldwide but other genotypes appear to be more restricted geographically. In the present study, an RT-nested PCR method was set up to detect delta infection from serum samples. Moreover, the target amplified sequ...

[ 6 ] - 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...
