objective: a number of studies have demonstrated the potential antitumor effects of saffron and its constituents on different malignant cells in vitro. it has been reported that a novel glycoconjugate isolated from corms and callus of saffron possesses cytotoxic activity against different tumor cellswith nitric oxide (no) production. these data suggest that the cytotoxic effect of saffron extra...

background: erythropoietin (epo) is a glycoprotein hormone function to regulate the production of red blood cells. deficiency of epo is known to cause anemia in chronically infected renal patients and they require regular blood transfusion. availability of recombinant epo has eliminated the need for blood transfusion and now it is extensively used for the treatment of anemia. glycosylation of e...

153 A pproximately 70% of childhood seizures can be treated successfully with medications. For the 30% of patients who are truly refractory to medical treatment—that is, who have had adequate trials with the appropriate medications—surgery may be an option for controlling the seizures. This article will review how surgical candidates are evaluated and how the surgical approach is tailored to th...

the anti-cancer activity of metal ions in the lanthanide group is being considered recently. it has been reported that cerium salts might stimulate the metabolism and therefore, produce anti-cancer effects. however, little is known about the effects of protein-cerium complex in controlling cancer cell growth. the aim of the present study was to elucidate the possible pathways for the cytotoxic ...

abstract background and aims: to identify and isolation of viruses a susceptible cell is need which can be primary or line. the use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. irkhbk cell line was originated from primary cells of bovine kidney by continuous passage. the aim of this study was to introduce the irkhbk cell lin...

objective: the study of physiological changes in recombinant cell lines provides useful information to improve production performance. in this study, we investigate the effects of an anti-cd33 chimeric igg4 expression on sp2.0 cell growth. methods: variable region genes of light and heavy chains of monoclonal antibody produced by m195 were cloned in pfuse-clig-hk and pfuse-chig-hg4 expression ...

background: both azadirachtin and rotenone, two botanical pesticides have shown inhibit the growth of cultured insect cells. the inhibitory effect of rotenone on cell growth is through disruption of electron transport chain, but exact mechanism of effect of azadirachtin on growth of cell is unknown. this study was carried out to compare the effect of these phytochemical on oxygen consumption by...

background: most cancer cells become resistant to anti-cancer agents. in the last few years, a new approach for targeted therapy of human cancer has been developed using immunotoxins which comprise both the cell targeting and the cell killing moieties. methods: in the present study, the recombinant shiga toxin a1 subunit fused to human granulocyte-macrophage colony stimulating factor (a1-gm-csf...

in this syudy a continuous bovine kidney cell line derived from a primary bovine kidney cells was established for the first time in iran. the cells were originating from two-day-old normal male calf of holstein breed. the cell cultures were continuously passaged following complete proliferation of primary cells. the specific properties or characteristics of the cell were defined using cytogene...

background: the rh antigens are expressed as parts of a protein complex in the rbc membrane. this complex is a tetramer, consisting of two molecules of rhag and two molecules of rh proteins. to express rhd in rbc membrane, expression of rhag is essential. this co-expression only occurs in the erythroid lineage. k562 cell line has an erythroid lineage. materials and methods: cord blood was used ...
