Chemical element same atomic number, or number of protons. Nuclear scientists, however, define a pure element as one that consists of only one stable isotope. For example, a copper wire is 99.99% chemically pure if 99.99% of its atoms are copper, with 29 protons each. However it is not isotopically pure since ordinary copper consists of two stable isotopes, 69% Cu and 31% Cu, with different numbers of neutrons. However, a pure gold ingot would be both chemically and isotopically pure, since ordinary gold consists only of one isotope, Au. Atoms of chemically pure elements may bond to each other chemically in
CU-2010 and CU-2020 of free radicals and less lipid peroxidation with the amount of malonaldehyde in the heart tissue being reduced. However, the activation of neutrophils does not seem to be altered. CU-2010 and CU-2020 improve coronary endothelial function similarly to aprotinin. Unlike aprotinin, at high doses, their anti-inflammatory properties allow for the improvement in the recovery of contractility in the left ventricle after ischemic conditions, and increase the protection of the myocardium. Moreover, CU-2010 and CU-2020 do not compromise clot strength, and do not affect the function of vascular smooth muscle. CU-2010 and CU-2020 CU-2010 and CU-2020 are synthetic compounds that act
