Prevalence of Hepatitis B Virus Markers among the Women with Breast Cancer.

Introduction: Breast cancer represents a formidable peril to the female populace on a worldwide level. The association between breast cancer and various factors, including viral infections, has been extensively investigated. Recently, the link between HBV infection and breast cancer patients has garnered attention.

Status of anti-HEV IgG and IgM antibodies among the hemodialysis patients in southwest region of Iran.

Background And Objectives: Hepatitis E Virus (HEV) account for acute hepatitis, fulminant liver failure and chronic hepatitis worldwide. Several high risk groups including hemodialysis (HD) patients are at risk of HEV infection. Based on consequences of HEV infection it is important to determine the serological and molecular epidemiology of HEV in HD patients.

Parechovirus and enteroviruses among young infants with sepsis in Iran.

Background And Objectives: Human parechoviruses (HPeV) and Human enteroviruses (EV) frequently cause a sepsis-like illness in young infants (younger than three months). Therefore, this study was conducted to determine the frequency of HPeV and EV among the young infants with clinical signs and symptoms of sepsis in Ahvaz city, Iran.

Materials And Methods: The blood specimens were collected from 100 (younger than 90 days hospitalized infants) including 54 (56.

In silico functional and structural characterization of hepatitis B virus PreS/S-gene in Iranian patients infected with chronic hepatitis B virus genotype D.

Objective: Chronic hepatitis B (CHB) virus infection is the most prevalent chronic liver disease and has become a serious threat to human health. In this study, we attempted to specify and predict several properties including physicochemical, mutation sites, B-cell epitopes, phosphorylation sites, N-link, O-link glycosylation sites, and protein structures of S protein isolated from Ahvaz.

Materials And Methods: Initially, hepatitis B virus DNA ( DNA) was extracted from five sera samples of untreated chronic hepatitis B patients.

Dominance of Variant Human Herpesvirus 6 A Among Hemodialysis Patients, Ahvaz, Iran.

Introduction: Hemodialysis (HD) patients are a high-risk population for acquiring blood-borne viruses such as HHV-6. HHV-6 can remain latent in the host cells after primary infection; the reactivation of virus may result complications such as seizure, respiratory failure, hepatitis, and encephalitis. There is a limited report concerning HHV-6 infection in HD patients in Iran.

The AP-1 pathway; A key regulator of cellular transformation modulated by oncogenic viruses.

Cancer progression is critically associated with modulation of host cell signaling pathways. Activator protein-1 (AP-1) signaling is one such pathway whose deregulation renders the host more susceptible to cancer development. Oncogenic viruses, including hepatitis B virus, hepatitis C virus, human papilloma virus, Epstein-Barr virus, human T-cell lymphotropic virus type 1, and Kaposi's sarcoma-associated herpes virus, are common causes of cancer.

Human Cytomegalovirus DNA among Women with Breast Cancer.

Breast cancer is the most common cause of death among women worldwide. Although there are many known risk factors in breast cancer development, infectious diseases have appeared as one of the important key to contribute to carcinogenesis formation. The effects of Human Cytomegalovirus (HCMV) on women with breast cancer has been recently studied and reported.

Molecular epidemiology of JC polyomavirus in HIV-infected patients and healthy individuals from Iran.

JC polyomavirus (JCPyV) is the causative agent for progressive multifocal leukoencephalopathy (PML) in immunocompromised patients. More than 40% of healthy population excretes JCPyV particles in their urine. As JCPyV is ubiquitous in human, the definition of genotype distribution can help trace population migration.

Frequency of Epstein–Barr Virus DNA in Formalin-Fixed Paraffin-Embedded Tissue of Patients with Ductal Breast Carcinoma.

Background: Ductal carcinoma is one of the most common breast cancer (BrC) among the women in the world. Several factors may involve in establishment of breast cancer. The role of viral infections have been investigated in BrC, Among them the association of Epstein Barr virus have been reported in the patients with breast cancer type ductal carcinoma.
