Cells are active components in their environment and constantly adjusting their performance to improve extracellular milieu changing. This approach is reflected their tends of maintaining intracellular homeostasis. When the cells encounter stress or pathologic stimuli, they can undergo a new manner (adaptation) and new steady state for achieving viability and function. If the external stress is...

death is something real which is fully accepted by human being, the definition of death is different among public and scientists such as philosophy experts and biologists. here we leave the philosophy content to themselves and look at the death from the biological point of view which may be some kind of philosophy as well. in biological science the death is well defined so it is the end of life...

background and objective: garlic has been known worldwide as a dietary constituent with many pharmacological effects. the present in vitro study was designed to investigate the putative anticancer effect of garlic extract on cancer cells, and if this effect was through apoptosis induction. material and methods:  human colon adenocarcinoma cells ht29 were treated with different doses (1, 5 and 1...

in many acute leukemias, normal differentiation does not occur. however, in many cell lines derived from hematologic malignancies, differentiation or programmed cell death (apoptosis) can be induced by variety of agents including: vitamin analogs, demethylating agents, cyclic amp analogs and anti-proliferative agents. to the best of our knowledge there has been not any study specifically to ana...

Abstract Cancer is the leading cause of death worldwide. Current anticancer drugs involve various toxic side effects; efforts are ongoing to develop new anticancer agents especially from the screening of natural compounds. Present study investigated cytotoxic effects and mode of cell death induced by the Caspian cobra venom in some human cancer cell lines. Cytotoxic effects of snake venom toxin...
