Induction of apoptosis in human tumor cell lines by platelets
Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thromb...
متن کاملPotatoes: Source of Laboratory Reagent for Human Platelets Research
Irish potatoes is rich in carbohydrate, with varied glucose levels. It is also a very good source of apyrase, an enzyme used for platelet storage. The aim of this study was to explore Irish potatoes as an easily available source for apyrase extraction and purification. Apyrase was extracted from 5 Kg of Irish potatoes. Platelets were derived from 5-10 ml of human whole blood and G6PD activity w...
متن کاملGlucose turnover and gluconeogenesis in human pregnancy.
The rate of appearance (Ra) of glucose in plasma and the contribution of gluconeogenesis were quantified in normal pregnant women early ( approximately 10 wk) and late ( approximately 34 wk) in gestation. Their data were compared with those of normal nonpregnant women. Glucose Ra was measured using the [U-13C]glucose tracer dilution method. Gluconeogenesis was quantified by the appearance of 2H...

متن کاملTocopherol in human platelets.
A spectrophotometric method was used to determine the total tocopherol levels in platelets, plasma, and erythrocytes from human subjects. The platelets contained about three times as much total tocopherol per cell as erythrocytes. This difference was not related to the content of polyunsaturated fatty acids in platelets and erythrocytes. In vitro incubation resulted in significant uptake of toc...
