Prior works, such as the Tallinn manual on the international law applicable to cyber warfare, focus on the circumstances of cyber warfare. Many organizations are considering how to conduct cyber warfare, but few have discussed methods to reduce, or even prevent, cyber confict. A recent series of publications started developing the framework of Cyber Peacekeeping (CPK) and its legal requirements...

Since creatine phosphokinase (CPK) is found predominantly in myocardial and skeletal muscle cells, in contrast to cells participating in the inflammatory response, it was considered likely that measurement of activity of this enzyme in the heart would provide a sensitive and relatively specific index of the extent of ischemic injury following acute coronary artery occlusion. Accordingly, CPK ac...

In order to evaluate methods for detecting peri-operative myocardial damage we studied 41 patients before and serially following coronary artery bypass graft surgery utilizing the 12-lead ECG, serum MB-CPK measurements, and 99mTc pyrophosphate myocardial scans. Six of the 41 patients (15%) developed persistent new Q waves after surgery. Six other patients demonstrated ischemic ST-T wave changes...

Addition of sulfhydryl groups to the reaction mixture, to stabilize serum creatine kinase (creatine phosphokinase, CPK), results in apparent increases in the activity of this enzyme in many sera. In addition, in sera from patients just after myocard ial infarction, assays for sulfhyd ryl-activated CPK have a different clinical pattern than do those for CPK assayed without sulfhydryl activators:...

I n 1954, LaDue et al' first noted rises in serum glutamic oxaloacetic transaminase (SGOT) enzyme levels following myocardial infarction. This important observation led to the evaluation of this and other serum enzyme systems as specific and sensitive mdi-cators of myocardial infarction. Elevation of serum creatine phosphokinase (CPK) appeared to be a more sensitive conventional serum enzyme cr...

We investigated the relationship between serum creatine phosphokinase (CPK) activity and energy expenditure in young adults and evaluated whether serum CPK activity is a useful index of energy expenditure. These data were obtained from 225 (men: 94, women: 131) healthy young adults. The results of the survey were as follows: In men, there was a statistically significant correlation between seru...

This is the first identification of a Ca2+-inhibitable casein kinase (CPK) which we have isolated from the 100000 x g supernatant of Paramecium cell homogenates. The 1000-fold enriched CPK activity depends on millimolar Mg2+ and is inhibited by low concentrations of heparin or by > or = 100 microM Ca2+. Enzyme activity is stimulated by polylysine or polyarginine with either casein or with speci...

Evidence is presented that serum creatinine phosphokinase (CPK) activity is of no direct value in screening patients for susceptibility to malignant hyperpyrexia and does not correlate with halothane-induced muscle contracture or the presence of myopathy. Widely differing CPK values were found at different times in the same people. In most "malignant hyperpyrexia" families the susceptible patie...

A transient but considerable rise in serum creatine phosphokinase (CPK) levels occurred in six boys aged between 8 and 11 years and suffering from phenothiazine-induced dystonia. In one boy (Case 4), after the CPK level had returned to normal after withdrawal of the drug, its reintroduction orally at lower dosage caused a slight increase in the level of CPK in the absence of any recurrence of t...

Effect of cocaine on leakage of creatine kinase from isolated fast and slow muscles. levels of serum creatine kinase (CK), we determined whether cocaine can . A control group comprised patients who were not cocaine users and satisfied the. RESULTS: The CK level in the cocaine group was 931 +/1,785 U/L (mean . Effects of cocaine on leakage of creatine kinase from skeletal muscle: in vitro. Serum...
