conclusions the elevation of hmw-alp activity in cu treated animal suggests the occurrence of biliary disease. this may be used as a biomarker for the diagnosis of copper toxicity. results obtained data showed that with increasing administration of copper, the alp activity was elevated significantly. in comparison with the control group the elevations were between 20%-56% using gel filtration c...

OBJECTIVE Bone metastasis is frequently associated with nasopharyngeal carcinoma. The diagnosis and follow-up of bone metastatic patients usually relies on skeletal X-ray and bone scintigraphy, which are time-consuming and costly. This study aimed to evaluate whether serum alkaline phosphatase offers clinical value in predicting the clinical response and survival outcome for skeletal metastatic...

Treatment of immature mice with both follicle-stimulating hormone and human chorionic gonadotrophin in vivo resulted in large increases in the specific activities of ovarian alkaline phosphatase and alkaline nucleotidase. The specific activities of other ovarian enzymes studied were not altered by gonadotrophin treatment. A simultaneous change in the Michaelis constant of ovarian alkaline phosp...

Desensitization of adenylate cyclase-coupled beta-adrenergic receptors in avian erythrocytes results in a 40-65% decrease in agonist-stimulated adenylate cyclase activity and correlates with increased phosphorylation of beta-adrenergic receptors. To assess the role of phosphorylation in desensitization, membranes from isoprenaline- and dibutyryl cyclic AMP-desensitized turkey erythrocytes were ...
