objective: this study presents an efficient, cost-effective method to improve proliferation and colonization of spermatogonial stem cells (sscs) in vitro. methods: isolated sscs from neonate mice were cultured in dmem culture medium with 10% fetal bovine serum (fbs). in the first phase of the study, the temperature was controlled by low intensity pulsed ultrasound stimulation (lipus) of the pla...

ba ckground: liver cancer is one of the deadly cancers with high prevalence in the east asia. likewise most of diseases, herbs and herbal medicine could be an easy and cost effective tool in prevention and possible cancer treatment. the present study investigated the ability of orthosiphon stamineus benth decoction to protect liver against hepatocellular carcinoma in carcinogenesis-induced anim...

runx3, a member of runt-related transcription factor (runx) proteins with tumor suppressor effect, is a tissue–restricted and cancer related transcription factor that regulate cell proliferation and growth, as well as differentiation. in the present study, exogenous run3 was transiently expressed in ags (human gastric adenocarcinoma), with undetectable runx3 protein and in a549 (human lung carc...

in this presentation, we review briefly on biogenesis of peroxisomes with regard to the recent findings on biogenesis. peroxisomes perform a range of various functions as oxidation of very long chain fatty acids, generation and removal of hydrogen peroxide, while peroxisomes have also been implicated in β-oxidation of aromatic and cyclic compounds, synthesis of plasmalogens, isoprenoids, lysine...

background: apart from genetic and environmental factors, activation of autoreactive mechanisms has been proposed to play a role in the pathogenesis of schizophrenia. in re-cent years, considerable work has been carried out to understand the role and contribution of the immune system in this disease. objective: to investigate the t cell response to phytohaemagglutinin (pha) and determine the se...

bleomycin (blm)as an anti-cancer agent causes tissue toxicities through dna damaging and cell deaths. the aim of this study was to investigate the effects of thymol against genotoxicity and anti-proliferation induced by blm in normal human lymphocytes and ovarian cancer cells.peripheral blood samples were collected from human volunteers and were incubated with thymolat different concentrations ...

luteolin is a flavone in medicinal plants as well as some vegetables and spices. it is a natural anti-oxidant with less pro-oxidant potential but apparently with a better safety profile. the purpose of this study was to investigate the molecular mechanism of luteolin-mediated apoptosis of mg-63 human osteosarcoma cells. mtt assay kit was employed to evaluate the effects of luteolin on mg-63 cel...

chamaemelum nobile (asteraceae) commonly known as 'roman chamomile' is a medicinal plant used for numerous diseases in traditional medicine, although its anticancer activity is unknown. the present study was carried out to investigate the anticancer as well as apoptotic activity of ethyl acetate fraction of c. nobile on different cancerous cell lines. the cells were treated with varyi...

stem cell therapy could have great potential for the treatment of a wide variety of diseases. stem cells might have the ability to differentiate into a widespread cell types, and to repopulate and revitalize the damaged cells with healthy tissue, and improve its performance. we provide here the evidence supporting the critical use of stem cell as a treatment in disease conditions existing with ...

gamma irradiation is routinely used for suppression of lymphocyte function in transfusion and transplantation procedures. in recent years, some investigators focused on the effects of ionizing radiation on special aspects of lymphocyte function and considered the possibility of its clinical application for treatment of some immunological disorders. in this study, we evaluated the effects of fiv...
