PALLADIUM CATALYSTS.Chloride poisoning is known as having an inhibitor effect in the activity of metal catalysis.In this work in situ infrared spectroscopy (FTIR) of adsorbed carbon monoxide and x-ray photoelectron spectroscopy (XPS) were used to investigate the effect of chloride presence in the electronic metal density in the d subshell of palladium dispersed on alumina.The chloride poisoning effect was interpreted as an electronic effect since a weak back-bonded Pd-CO was formed due to the decrease ...

ACTIVATION OF MICE PERITONEAL MACROPHAGES BY PALLADIUM(II) ORGANOMETALLIC MONONUCLEAR COMPOUNDS.The immune responses are mediated by a variety of cells that, when activated, produce a number of molecules.Macrophages are the first cells to take part in the immune response releasing many compounds in the extracellular environment such as H 2 O 2 .Taking into account this aspect we evaluated the activation of an immunological system, in vitro, by determining the H 2 O 2 released in cultures of peritoneal ...

Carnitine palmitoyltransferase I is assumed to be rate limiting for beta-oxidation in all tissues. However, the concentration of malonyl-CoA in heart and muscle is high and is enough to completely inhibit beta-oxidation if this assumption is correct. In this review, we consider whether: (i) there is a malonyl-CoA-insensitive carnitine palmitoyltransferase I activity; (ii) the measured malonyl-CoA concentration in the heart is physiologically meaningful; and (iii) carnitine palmitoyltransferase I is ...
