Background: Some scientific data have been reported the positive effects of natural antioxidants on modulating the Total Antioxidant Capacity and muscular damage indicators. The aim of this research was to examine the effects of Short-Term Grapefruite juice Supplementation on Lipid Peroxidation and Total Antioxidant Capacity and some muscular damage indicators in young men following a session ...
Determination of the MB isoenzyme of creatine kinase in patients with acute myocardial infarction may be disturbed by the presence of macro creatine kinase. The relative molecular mass of this form of creatine kinase in human serum is at least threefold that of the ordinary enzyme, and it is more thermostable. Here we describe our method for determination of macro creatine kinases and an easy-t...
this study intended to compare the effect of consuming creatine and mixed creatine-carbohydrate supplementations on the anaerobic power and cellular damage indices (ck, ldh) in males aged between 15 and 18 in the city of kouhrang. for this purpose, 36 subjects (mean age 16.42±0.90 yrs, weight 54.85±9.96 kg, and height 167.75±8.28 cm) were selected by available method. first, blood samples were ...
AIMS Studies on the glycoprotein IIb-IIIa receptor blocker abciximab in patients undergoing percutaneous coronary intervention consistently show a reduction in procedure-related myocardial infarction. Some such infarcts are characterized by elevated creatine kinase or creatine kinase-MB, without apparent clinical symptoms. The clinical relevance of such 'creatine kinase leaks' has been question...
The time-related frequency of elevated results for the mass concentrations of the MB isoenzyme of creatine kinase and of troponin T were compared with that of creatine kinase and creatine kinase-MB activity in patients with acute myocardial infarction. Patients (322; 175 with and 147 without myocardial infarction) consecutively admitted for evaluation of possible acute myocardial infarction wer...
OBJECTIVE To assess the diagnostic value at admission of creatine kinase MB mass concentration, alone or in combination with electrocardiographic changes, in suspected myocardial infarction. DESIGN Prospective study of all consecutive patients admitted within 12 hours after onset of chest pain to a coronary care unit for evaluation of suspected myocardial infarction. SETTING Large regional ...
Previous studies have suggested that MM creatine kinase is a muscle-specific protein and is not present in adult brain tissue. We have isolated a protein from human brain with an apparent molecular weight of 43,000 as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis which is identical to the muscle M creatine kinase isoenzyme subunit at all 30 sequenced amino acid residue...
Purification of human mitochondrial creatine kinase has been difficult and procedures that were highly successful in purifying canine enzyme failed for human mitochondria1 creatine kinase. In the present study, we employed ultracentrifugation to remove the lipid, urea to prevent aggregation, followed by a final step of chromatofocusing which yielded a preparation of human mitochondrial creatine...
Adenylate kinase (EC 2.7.4.3) interferes positively in the serum creatine kinase (EC 2.7.3.2) assay when the rate of ATP production is monitored by a coupled enzyme system. A dual assay, measuring creatine kinase and adenylate kinase activity, was used to evaluate AMP and other possible adenylate kinase inhibitors that would permit specific measurement of creatine kinase activity in the presenc...
