the ultimate goal of the periodontal treatments is a regeneration of periodontium. recently, laser irradiations are commonly used to improve wound repair. because of many controversies about the effects of laser on soft tissue regeneration, more in vitro studies are still needed. the aim of the present in vitro study was to compare the effects of different doses of er:yag (erbium-doped:yttrium,...

background: in this study, the effects of three structural analogues of adenosine upon proliferation of human tumor cells were investigated. previous research showed a cytotoxic effect of adenosine via a3 receptor and a1 receptor and sometimes this effect was receptor independent. the researches showed a differential cytotoxic effect of adenosine and its a3 agonists on cancerous cells, while ot...

dendritic cells (dcs) induce pathogen-specific t cell responses. we comprehensively studied the effects of addition of maturation stimulus, fibroblasts (fibroblast conditioned medium), pha activated t cells (t cell conditioned medium), and mixture of fibroblast & pha activated t cells (fcm-tccm) conditioned media on maturation of dcs. monocytes were cultured with gm-csf and il-4 for five da...

background: cd19 is a pan b cell marker that is recognized as an attractive target for antibody-based therapy of b-cell disorders including autoimmune disease and hematological malignancies. the object of this study was to stably express the human cd19 antigen in the murine nih-3t3 cell line aimed to be used as an immunogen in our future study. methods: total rna was extracted from raji cells i...

Two cell lines with different in vitro growth patterns were established from the pleural fluid of a patient with malignant epithelial pleural mesothelioma. The cell line established in RPMI 1640 supplemented with human AB serum had an epithelial morphology, while the cell line established in fetal calf serum-supplemented medium had a fibroblast-like morphology. Exposure of the fibroblast-like c...

   Cytotoxicity of depleted uranium, as a byproduct of military has been came to spotlight in recent decades. DU is known as a chemical rather than radioactive hazard and efforts to illustrating its mechanism is undergo, but the precise complete molecular mechanisms are still unclear. Recent studies showed that uranium induces biological changes in many different target tissues, such as the kid...
