background : hepatitis includes a wide range of clinical and pathological conditions. the beta-2 microglobulin (ãÿ2m), as part of thehla complex, is responsible for transmission of viral antigens on the surface of liver cells. the purpose of this study is to determine the concentration of salivary ãÿ2m as a marker of viral proliferation in subjects who are hbsag + , hbv dna pcr + compared with ...

Background: Immunophenotyping in the rare group of nodal Peripheral T-cell Lymphomas (PTCL) exposes interesting features such as T-cell marker downregulation and paradoxically, the presence of reactive, clustered large-sized CD20 positive B-cells (B-cell proliferation). Epstein-Barr virus (EBV) has been suggested as a putative etiology in pathogenesis of B-cell lymphoma. We aimed to review the ...

background: as for human trichomoniasis the host-parasite relationship is very complex, and the broad ranges of clinical symptoms are unlikely be attributable to a single pathogenic mechanism. specific random amplified polymorphic dna (rapd) markers of 490 bp, 720 bp and 460 bp using the primers tv-5, opa-6 and opa-11, respectively, were reported. this was the first description of possible ge­n...

background the mutations of lhbs in pre-s, especially in pre-s2, are definitive in hepatocellular carcinoma (hcc) associated with hbv. however, the mechanisms of the n-glycosylation modification in lhbs are unclear. the n-glycosylation modification of lhbs affects endoplasmic reticulum stress, cell proliferation and its secretion which was further studied. objectives the objectives of our studi...

Background and Aims: Rubella is predominantly a childhood disease that is endemic throughout the world and when rubella outbreaks occur, they are accompanied by birth defects following congenital rubella syndrome. Immunity to rubella virus as a teratogenic agent has an important role for prevention of these serious congenital defects. Lymphocyte proliferation assay is a way for investigation of...

Background and Aim: Recently, several studies have indicated that the central nervous system has the capacity for endogenous repair. But, the proliferation capacity of endogenous neural stem cells (NSCs) isn’t sufficient for the treatment of neurodegenerative diseases. So, it sounds that stimulation of endogenous NSC proliferation is essential for neuroregeneration. The aim of this study ...

Introduction: Now days, several studies have indicated the central nervous system has capacity for endogenous repair. But, the proliferation of endogenous neural stem cells (NSCs) is insufficient for treatment of neurodegenerative diseases. So, it sound that stimulation of endogenous NSC proliferation is essential for neuroregeneration. The Acca sellowiana (Feijoa) extract as herbal extract is ...
