[ 1 ] - Immune dysregulation in children with allergic asthma, a close relationship between IL-17 but not IL-4 or IFN-, and disease severity
Background : Allergic asthma is a chronic inflammatory disease of airway that often determined with degrees of inflammation, hypersensitivity, bronchial constriction and airway changes. Th1, Th2 and Th17 cells are the main cells involved in the pathophysiology of asthma. . Therefore, this study evaluated Th1, Th2, and Th17 cells functions by assessment the expression of INF-g, IL-4, and IL-17 g...
[ 2 ] - 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 ...
[ 3 ] - Blood groups: In Health and Diseases
ABO blood type antigens are polymorphic, inherited structures presented on the surface of red blood cells. Although ABO blood group antigens is the most important antigens in transfusion medicine, its main role is not clearly clarified. Correlation between ABO blood group and susceptibility to certain infectious and non-infectious diseases is a controversial issue. Since, lack of blood type ant...
[ 4 ] - Generation of CHO Stable Cell Line Overexpressing HER2: an In Vitro Model for Breast Cancer
Background: Breast cancer is the most common female malignancy and the leading cause of cancer mortality in women worldwide. The human epidermal growth factor receptor2 (HER2) is a transmembrane tyrosine kinase receptor that is usually overexpressed in human breast cancers. Stable cell lines heterogeneously overexpressing HER2 are highly required as in vitro models for breast cancer research. T...
[ 5 ] - The Role of aac(6)-IIa and ant(2'')-Ia Genes and the Presence of Class 1 Integrons in Resistance of Pseudomonas Aeruginosa Clinical Isolates against Aminoglycosides
Background and purpose: The aminoglycoside modifying enzymes (AMEs) and class 1 integrons in clinical isolates of pseudomonas aeruginosa are the major factors leading to rapid spread of antibiotic resistance. The aim of the present study was to investigate the frequency of aac(6)-IIa, ant(2'')-Ia, and class 1 integrons in clinical isolates of pseudomonas aeruginosa. Materials and methods: For ...
[ 6 ] - 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...
[ 7 ] - Designing an ELISA Method for Measurement of Human IgG and IgM Antibodies against SARS-CoV-2
Background and purpose: Coronavirus disease 2019 (COVID-19) is a respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In this study, an indirect ELISA method was designed to measure the human IgM and IgG antibodies against SARS-CoV-2. Materials and methods: Protein sequence of nucleocapsid antigen from SARS-CoV-2 was expressed in E. coli BL21 and then was...
