the interaction of radiation with cells and tissues has a random nature. therefore, understanding the random nature of cell killing that is determined by poisson distribution statistics is an essential point in education of radiation biology. radbiostat is a newly developed educational matlab-based software designed for computer-assisted learning of the target theory in radiation biology. altho...
The base of this study has been demonstrated the use of different drugs and dosages on different tumour cell lines and finally the effect of these drugs on natural killerllimphokine activated killer (NK/LAK) Killing. Tumour cells as target , mononeuclear cell activated with inter leukin-2(LAK) as effector, anti cancer drugs like tamoxifen , pentoxifylline , cycloheximide and cisplatin as stimul...
background: perforin is known to be important in cytolytic activity mediated by natural killer (nk) cells. objective: to study the relationship between the efficiency of nk and lymphokine-activated killer (lak) cells activity, and the expression of perforin and hla class i molecules. methods: lak cells were generated by in vitro culturing of human peripheral blood lymphocytes (pbls) in the ...

Background: Multiple myeloma (MM) is a malignant plasma cell proliferative disorder with limited immunotherapy treatment because of T cell dysfunction. Objective: To investigate the immunomodulatory function of bone marrow mesenchymal stromal cells (MM-BMSCs) on CD8+ T cells. Methods: Proliferation and cytotoxicity were detected by c...
Background: Immunotoxins are comprised of both the cell targeting and the cell killing moieties. We previously established a new immunotoxin, i.e. Shiga toxin granulocyte macrophage-colony stimulating factor (StxA1-GM-CSF), comprises of catalytic domain of Stx, as a killing moiety and GM-CSF, as a cell targeting moiety. In this study, the ability of the immunotoxin to induce apoptosis and dou...
fusion of two genes at dna level produces a single protein, known as a chimeric protein. immunotoxins are chimeric proteins composed of specific cell targeting and cell killing moieties. bacterial or plant toxins are commonly used as the killing moieties of the chimeric immunotoxins. in this investigation, the catalytic domain of shiga-like toxin (a1) was fused to human granulocyte macrophage c...
Introduction: Stereotactic body radiotherapy delivers hypofractionated irradiation with high dose per fraction through complex treatment techniques. The increased complexity leads to longer dose delivery times for each fraction. The purpose of this study is to investigate the impact of prolonged fraction delivery time with high-dose hypofractionation on the killing of cultured ACHN cells.Method...
