Introduction Mixed copper–magnesium oxide has been studied by many authors, since this material is highly active in several catalytic processes, including oxidation reactions [ 1 , 2 ] and the water–gas shift reaction [ 3

Introduction Low-temperature oxidation of carbon monoxide (CO) is one of the most important catalytic reactions from the viewpoint of industry and environment, especially for cleaning air, producing ultra high-purity gases, and

to below 10 ppm in excess of H 2 , H 2 O and CO 2 , which is a current challenge in heterogeneous catalysis. This process is called preferential oxidation of CO (CO-PROX) [ 4 – 6 ], rather than selective oxidation as it is not possible to suppress H 2

Introduction At present great interest is devoted to bismuth-based oxides because they present a wide variety of materials where bismuth is found either as an essential component or as an additive. So far these materials have

molecular mediator of hypoxia-induced apoptosis is the tumor suppressor transcription factor p53. It is suggested that p53 may induce apoptosis by stimulating the expression of Bax and/or repression of Bcl-2 expression ( 23 ). Increased oxidative stress was
