The dual radionuclide myocardial distributions of imaging agents potassium43 (49K) and technetium-99m stannous pyrophosphate ('9mTc-PYP) were studied in a 24-hour closed chest canine infarct preparation. In multiple myocardial biopsies in 20 dogs, tissue levels of both radionuclides were compared to either an index of tissue viability (myocardial creatine phosphokinase [CPK] depletion), or to e...

objective: to evaluate the plasma creatine phosphokinase (cpk) level after a single injection of methotrexate (mtx) as a predictor of treatment success in ectopic pregnancy (ep). materials and methods: in this prospective study, seventy nine women older than 18 years treated with methotrexate for ectopic pregnancy were evaluated for cpk and β-subunit of human chorionic gonadotropin (βhcg) level...

Process yield has been the most basic and common criterion used in the manufacturing industry for evaluating process capability. The Cpk index has been used widely in the manufacturing industry. In this note, we considered a generalization of Cpk index which handles processes involving a target T with asymmetric tolerances. Particularly, we established a formula for measuring the PPM non-confor...

Cats subjected to coronary artery occlusion were used to study the effect of methylprednisolone on the release of lysosomal acid hydrolases and creatine phosphokinase (CPK) from ischemic myocardial tissue. Plasma CPK activity was increased significantly 2 hours after occlusion and increased eightfold 5 hours after ligation in vehicle-treated cats. Intravenous administration of methylprednisolon...

The histochemical creatine phosphokinase (CPK) tetrazolium test has been evaluated to detect recent human myocardial infarction in gross slices of the heart at necropsy. The demonstration of the lesion with this method has been assumed to result from local loss of CPK from the damaged myocardium. However, the present study indicates that the mechanism involved depends on localising NADPH tetraz...

The PKU sample, if taken after the 3rd day, is suitable for Duchenne muscular dystrophy screening using creatine phosphokinase (CPK) levels. 101 babies (53 girls and 48 boys) had CPK levels measured on filter paper blood specimens taken by heel prick on the 1st and 4th days of life. The method used was that described by Zellweger and Antonik (1975). The CPK levels were markedly raised on the 1s...

Significantly elevated serum creatine phosphokinase concentrations have been demonstrated in 70% of patients with acute psychosis. Elevations in spinal fluid creatine phosphokinase (CPK) activity have been reported in several neurological diseases, often in association with otherwise normal routine spinal fluid studies. Spinal fluid and serum were obtained simultaneously from 11 patients with a...

Sustained increase of serum creatine phosphokinase (CPK) concentrations and muscle abnormalities have been reported in patients taking raltegravir (RAL). In this report, we describe a case of sustained and asymptomatic increase of serum CPK concentrations associated with raltegravir, zidovudine, and lamivudine in an HIV-1 experienced patient with intolerance to protease inhibitor, abacavir and ...

Pan-caspase inhibition reduces tubular apoptosis and proliferation and slows progression of disease in a rat model of polycystic kidney disease (PKD). It is unknown, however, which specific caspases are involved in PKD progression. Because caspase-3 is a major mediator of apoptosis, its role in autosomal recessive PKD was determined. Mice with caspase-3 gene deletion were crossed with mice harb...

Since polycystic kidney disease (PKD) was first noted over 30 years ago to have neoplastic parallels, there has been a resurgent interest in elucidating neoplasia-relevant pathways in PKD. Taking a nontargeted metabolomics approach in the B6(Cg)-Cys1(cpk/)J (cpk) mouse model of recessive PKD, we have now characterized metabolic reprogramming in these tissues, leading to a glutamine-dependent TC...
