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 that by aprotinin prevent early thrombosis, providing an anti-coagulatory effect in patients, and prolonging activated partial thromboplastin time (aPTT). Prolonged time for lysis further displays the anti-fibrinolytic characteristics of these drugs. Together, the anti-coagulatory and anti-fibrinolytic effects reduce the chance of thrombo-embolic complications. CU-2010 and CU-2020 possess anti inflammatory effects due to their inhibition on plasma–kallikrein. CU-2010 and CU-2020 reduce leukocyte-endothelial interaction, migration of leukocytes, adhesion molecules expression, rate of apoptosis, inflammatory genes expression (especially TNF-α) and protein synthesis, all events which normally occur after myocardial ischemia/reperfusion. These anti-inflammatory effects of the serine protease inhibitors result in a reduced amount
