background : the study was aimed to show the effect of molecular mechanism of aqueous garlic extract (age) on expression of ifnγ and inos genes in leishmania major . methods : leishmania major promastigotes (mrho/ir/75/er) were added to the in-vitro cultured j774 cell line, the cells were incubated for 72 hours. various concentrations of garlic extract (9.25, 18.5, 37, 74, 148 mg/ml) were added...

introduction: transient receptor potential vanilloid type 1 (trpv1) and protein kinase cγ (pkcγ) are involved in sensitization/desensitization to noxious stimuli. we aimed to examine the gene expression levels of trpv1 and pkcγ in rat lumbosacral cord and midbrain on days 1, 4 and 8 of induction of morphine analgesic tolerance. methods: two groups of male wistar rats received twice daily saline...

viral protein-1 (vp1) is a major capsid protein of coxsakievirus b3 (cvb3) that plays an important role in directing viruses towards permissive cells and acts as a main antigenic site of the virus in eliciting of host immune response, hence it seems vp1 can be considered as a vaccine candidate against cvb3 infection. in this study, cdna of vp1 was prepared, cloned into pet expression vector and...

background: human embryonic stem cells (hesc), which are derived from the inner cell mass of the blastocysts, have been considered to be pluripotent cells. in this study we examine the differentiating potential of hesc into hepatocytes by characterization of the expression of endoderm and liver-specific genes. methods: hesc were cultivated in suspension to form aggregates, the embryoid bodies. ...

objective(s):with regard to pharmacological effects of carvacrol on the respiratory system, its effect on cytokines genes expression in splenocytes of asthmatic mice was examined in this study. materials and methods:splenocytes were isolated from non-sensitized (control group), sensitized mice to ovalbumin (ova) (group s), and s animals treated with dexamethasone, and three concentrations of ca...

objective(s): stem cell differentiation into different cell lineages depends upon several factors, cell cycle control elements and intracellular signaling elements, including p15ink4b and p16ink4a genes. epigenetics may be regarded as a control mechanism which is affected by these factors with respect to their promoter structure.   materials and methods: the cd34 + cord blood stem cells were pu...

bakground: multiple sclerosis (ms) is a cd4+ t cell-mediated autoimmune disease affecting the central nervous system (cns). it was previously believed that th1 cells were pathogenic t cells in experimental autoimmune encephalomyelitis (eae). however, the functional role of th1 cells in eae has been reconsidered upon the discovery of il-17- producing t cells which are consider as dominant effect...

results a total number of 43 specimens were studied, from which 9 were obtained from patients with metastatic prostate cancer. the expression of five examined genes had no correlation with psa level and gleason score. the expression of amacr decreased in metastatic prostate cancer (p = 0.02). the expression of other genes showed no difference between metastatic and non-metastatic tumors (p > 0....

BACKGROUND While there is interest in measuring the satisfaction of patients discharged from psychiatric hospitals, it might be important to determine whether surveys of psychiatric patients should employ generic or psychiatry-specific instruments. The aim of this study was to compare two psychiatric-specific and one generic questionnaires assessing patients' satisfaction after a hospitalisatio...
