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)
