Ginsenoside compound K (CK) is one of the effective ingredients in antitumor composition of ginsenoside. However, the poor water solubility and significant efflux have limited the widespread clinical use of CK. In this study, preparation of novel CK-loaded d-alpha-tocopheryl polyethylene glycol 1,000 succinate/poly(ethylene glycol)-poly(ε-caprolactone) mixed micelles (CK-M) is discussed to solv...

We study the exclusive decays of B meson into pseudoscalar charmonium states ηc and η ′ c within the QCD factorization approach and find that the nonfactorizable corrections to naive factorization are infrared safe at leading-twist order. The spectator interactions arising from the kaon twist-3 effects are formally power-suppressed but chirally and logarithmically enhanced. The theoretical deca...

Creatine kinase MB isoform (CK-MB) is a biochemical marker that is used to evaluate patients with suspected acute myocardial infarction. Rapid immunoassays to measure CK-MB mass concentration use various monoclonal anti-CK-MB antibodies, and these have been reported to be highly sensitive, specific, and free of interference [1]. Here, we report the first case of a false-positive CK-MB result (a...

In 2.9% of sera from 1253 unselected patients we detected two different types of macromolecular creatine kinases (CK; EC 2.7.3.2). One macro type was represented by immunoglobulin-linked CK: in sera containing macro CK-BB isoenzyme, 125I-labeled CK-BB was bound with high affinity to the immunoglobulin fraction. Furthermore, during electrophoresis, macro CK-BB mostly migrated between CK-MB and C...

In the course of a clinical comparison involving 204 parallel total creatine kinase (CK), creatine kinase-MB isoenzyme (CK-MB), and cardiac troponin I (cTnI) measurements, 12 patients were identified in whom cTnI was elevated while total CK was normal, as well as 2 patients in whom CK-MB was elevated while cTnI was normal. CK-MB relative index was elevated in 6 of the twelve cTnI-positive patie...

From 8322 patients for whom creatine kinase (CK; EC 2.7.3.2) isoenzyme analysis was ordered, we identified 136 patients with macro CK isoenzyme in their serum. There were 36 cases with type 1 (prevalence: 0.43%) and 100 cases with type 2 isoenzyme (prevalence: 1.20%). About three-fourths of the patients were ambulatory at the time of testing, and approximately 90% of the first 68 patients ident...

The arrival of large numbers of potent Sukhoi fighters in the Asia Pacific region has attracted the attention of analysts and media alike. Less visible but no less important is the recent proliferation across the region of Russian and indigenous precision guided munitions (PGMs). In many respects the Sukhois are both a delivery vehicle and marketing vehicle for Russian cruise missiles, standoff...

BACKGROUND Cardiac biomarkers are routinely obtained in the setting of suspected myocardial ischemia and infarction. Evidence suggests these markers may correlate with functional and clinical outcomes, but the strength of this correlation is unclear. The relationship between enzyme measures of myocardial necrosis and left ventricular performance and adverse clinical outcomes were explored. ME...

Purified, repeatedly washed, skeletal muscle myofibrils contain approx. 0.2 U of creatine kinase (CK) activity (equivalent to 2.5 micrograms CK) per milligram dry weight; this firmly bound CK activity is estimated to represent 3-5% of the total cellular CK. It had been shown previously that the myofibrillar CK, which can be quantitatively extracted at low ionic strength and purified to homogene...

We examined sera from sixdifferent groupsofpatientsfor CK-MB activity by means of two commercially available tests,an immunoinhibitionmethod (E. Merck) and the CK-MB test as used with the aca (Du Pont). In the first group of patients (suspicion of myocardial infarction) the correlationbetween the two methods was good: r = 0.9191, y = 1.068x0.888, = 18.7 U/L, = 19.0 U/L. Inthe second group,patie...
