The binding of azide ion to horse-heart myoglobins has been studied at pH 6.98 and at various temperatures. The results show that the azide complex is not completely loe spin and that the spin population is strongly dependent on temperature. We have shown that with some assumption it is possible to calculate the approximate fraction of high and low spin present at any temperature from the absorbance measurements. Corrections to the spin contribution at pH 6.98 to these values has been calculated. 相似文献

Apoptosis. Biochemical events and relevance to cancer chemotherapy. 总被引:25,自引:0,他引:25
Two distinct pathways for cell death exist. Compared to necrotic death, physiological or apoptotic cell death is an active suicidal process that consists of a cascade of well-regulated synthetic events. Participation of specific genes in apoptosis, and its possible molecular regulation, are considered in order to investigate the mechanism of cell death induced by some cancer chemotherapeutic agents. 相似文献
