BACKGROUND Multi-slice computed tomography (MSCT) can be useful before percutaneous mitral annuloplasty (PMA) procedures to visualize the relations between the mitral valve (MV), left circumflex artery (LCx) and coronary sinus (CS). METHODS AND RESULTS We performed a 64-slice MSCT in 196 patients (109 male; age 56.6 ± 11.4) with suspected coronary artery… (More)
New visualization methods are helpful in the noninvasive diagnosis of heart diseases. However, sometimes epicardial and endocardial leads can cause problems due to a large number of artifacts. Based on the presented case, we conclude that it is possible to perform multi-slice computed tomography of coronary arteries despite the coexistence of transvenous… (More)
Endocardial leads can potentially cause problems during coronary vessels visualization in multislice computed tomography (MSCT) due to a large number of artifacts. Based on presented case, we conclude that it is possible to perform MSCT of coronary arteries and leads visualization despite coexistence of four endocardial leads.
An approximately threefold increase in glycogenolytic activity of the neutral alpha-1,4-glucosidase and a twofold increase in the same activity of the acid isoform have been found in extracts of anaplastic astrocytoma and glioblastoma multiforme tumors of brain tissue. "Maltase activity" of the respective enzymes increased by 60-80% in both kinds of tumor… (More)
In Part I of this study it was found that slow injection of acetylcholine causes an increase in phosphorolytic activity in the working heart and resting skeletal muscle, and at the same time decreases hydrolytic activity. At present, it is shown that atropine and tubocurarine do not inhibit this activity of acetylcholine, but that it is inhibited by… (More)
