Period 5 element Klaproth named the new element in 1798 after the Latin word for "earth", "tellus". Gold telluride minerals (responsible for the name of Telluride, Colorado) are the most notable natural gold compounds. However, they are not a commercially significant source of tellurium itself, which is normally extracted as by-product of copper and lead production. Tellurium is commercially primarily used in alloys, foremost in steel and copper to improve machinability. Applications in solar panels and as a semiconductor material also consume a considerable fraction of tellurium production. Iodine is a chemical element with the symbol I and atomic number 53. The name
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
