[ 4 ] - ارزیابی سرولوژیک ویروس اپشتین بار در بیماران مالتیپل اسکلروزیس
Background and purpose: Multiple Sclerosis (MS) is a disease of the central nervous system that is an auto-immune disease, where the immune system gets confused and attacks the nerve cells, damaging this protective layer of myelin sheath. The prevalence of MS is 52 per 100000 worldwide. The relation between Epstein-Barr virus (EBV) and MS is well understood but studies reported different result...

Background and purpose: Influenza A is an infectious disease caused by RNA viruses of the influenza viruses. Influenza viruses spread around the world in seasonal epidemics. It is estimated to affect %5-%15 of the global population and causing about 250000 to 500000 yearly deaths, rising to millions in some pandemic years. The aim of this study was an epidemiological survey of influenza A v...
[ 6 ] - آبله و آمادگی برخورد با حملات بیوتروریستی
Smallpox is a serious infectious disease to have ever afflicted mankind. Smallpox is caused by variola virus, which belongs to a family of viruses known as poxviridae. Pox viruses are large DNA viruses which are 200-400 nm. The smallpox prodrome is characterized by the sudden on-set of high fever (38.5°C-40.5°C) and malaise 10 to 14 days after exposure. As populations grew and migrated, the dis...
[ 7 ] - پاپیلوما ویروس و سرطان
Papillomaviruses are small tumor viruses with a genome of approximately 8000 base pairs. They are found in many different types and infect a wide range of animals (from birds to rabbits, dogs, sheep and cattle) and several primates including humans. So far, over 100 different types of human papillomavirus (HPV) have been identified, among which one-third infect epithelial cells in the genital t...
[ 8 ] - The Prevalence of HBV and HCV Infection in HIV Positive Patients in Norht of Iran
Background: HIV infected persons are also at risk for Infection with other pathogens, like Hepatitis B virus (HBV) and Hepatitis C virus (HCV). One of the main steps in the planning of treatment and prevention is the study of the HIV positive population who have HBV and/or HCV infection. The objective of this study was to determine the prevalence of HIV and Hepatitis B and C dual infection in ...
[ 9 ] - Prevalence of Influenza A/H1N1 Virus in North of Iran, 2013 to 2017
Background and purpose: Influenza viruses annually spread around the world in seasonal epidemics. The A/H1N1 virus causes more severe conditions compared to other types of Influenza A. This study is an epidemiological survey of influenza A/H1N1 virus in patients attending health care centers in north of Iran during 2013-2017.

[ 10 ] - Comparison of the Effect of Phenylalanine Arginine Beta Naphthylamide (PAβN) and Curcumin on Minimum Inhibitory Concentration of Aminoglycosides on Pseudomonas aeruginosa Clinical Isolates
Background and Objective: Efflux pump inhibitors (EPIs) can block efflux pumps and are helpful in potentiating the activity of aminoglycosides against Pseudomonas aeruginosa. The present study compared the effects of phenylalanine-arginine beta naphthylamide (PAβN) and curcumin on aminoglycoside minimum inhibitory concentration (MIC) on Pseudomonas aeruginosa clinical isolates. Materials and M...
[ 11 ] - Effect of Health, Medical, and Social Care on Quality of Life in a Group of HIV Positive Patients in Mazandaran Province, Iran
Background and purpose: AIDS, can cause psychological and social problems in patients and affects their quality of life. Therefore, infected people need more care. This study was conducted to investigate the effect of different care methods in quality of life of HIV+ patients. Materials and methods: HIV-positive patients in Mazandaran were divided into two groups of intervention (n=34) and con...
[ 12 ] - Examination of MHC-1 Expression by J774 Macrophage Cells Treated with Recombinant Protein HIV-1 Tat 49-59 / HPV16, 18, 6, 11 E7 In Vitro
Background and purpose: Human papillomavirus (HPV) is one of the infectious agents that causes genital and non-genital warts and skin cancers in humans. The E7 protein of this virus is one of the small oncoproteins that may be the main target in therapeutic vaccines. E7 protein with HIV-1 Tat peptide (49-59), plays a protective role that cause immune Th1 and CTLs response. The aim of this study...
[ 13 ] - Identification of Neuraminidase Gene Mutations of Influenza A/H3N2 Isolates in Mazandaran Province, 2016-2018
Background and purpose: Influenza is one of the viral infections of the respiratory system, which causes death in high-risk groups every year. The genomic changes of influenza virus make it susceptible to drug resistance, therefore, continuous monitoring of the influenza virus is highly important in order to recognize the efficacy of available drugs.
