Because creatine kinase (CK) appears in cardiac lymph after myocardial infarction, this study was undertaken to determine whether lymph inactivates CK in vitro and whether interruption of cardiac lymph flow influences estimation of infarct size based on plasma CK changes in conscious dogs. After the effects of incubation of canine myocardial CK in native, deproteinized, or sulfhydrylfortified l...

Using an isoelectric-focusing (IEF) method developed to quantitate MM isoenzyme-creatine kinase (CK) sub-band activity, we identified a reproducible time-varying pattern of these sub-bands in the serum of eight patients with acute myocardial infarction (MI). Our observations are consistent with the view that MM3-CK (the M2-CK dimer, the pure gene product) is converted intravascularly to MM2-CK,...

Creatine Kinase (CK) is the enzyme responsible for catalysing the exchange of phosphates in the creatine/phosphocreatine shuttle. Skeletal muscle CK is made up of 90% muscle CK (CKMM) and 10% heart CK (CK-MB). In muscle damage (e.g. rhabdomyolysis), extreme exercise and statin-induced myositis, serum CK can be raised in excess of 10 times the upper limit of normal. However, the recent discovery...

We develop a new comagnetometer using (21)Ne atoms with nuclear spin I=3/2 and Rb atoms polarized by spin exchange with K atoms to search for tensor interactions that violate local Lorentz invariance. We frequently reverse the orientation of the experiment and search for signals at the first and second harmonics of the sidereal frequency. We constrain 4 of the 5 spatial Lorentz-violating coeffi...

Visible and UV light spectra display striking differences in optical reflectivity for the two types of monatomic steps on copper (111) surfaces. Electronic structure calculations trace these differences to the specific contributions of p(axially) and p(radially) local densities of states, parallel and perpendicular to the steps, of the distinctly coordinated corner atoms. The local origin of th...

In this work, it is presented an approach to the local electron energy of first thirty-six atoms in their ground state using Rényi’s entropy defined terms density position and momentum spaces. To carry out our study, we calculated compared trends obtained from functionals kinetic, exchange, Coulomb energy, with entropy. Our results suggest that could be a good option perform studies on behavior...

The stability of local chain structures formed by Te atoms in liquid KxTe12x mixtures (x50.0, 0.2, and 0.5! is studied by ab initio molecular-dynamics simulations. It is confirmed by investigating the atomic and electronic structures that at x50.2, the chain structure of Te is stabilized by the presence of K atoms compared with the pure liquid Te, and that, at the equiatomic concentration, most...
