ABSTRACT The rate of label incorporation of various precursors into liver glycogen and exhaled carbon dioxide was investigated in rats 3, 6, 24 and 48 hours after cortisol injection. The glycogen concentration in the liver attained its maximum 24 hours after the hormone injection, whereas the total radioactivity of glycogen from [1-14C] glucose, [1–3-14C] lactate and [1,2-14C] glycerol reached the highest level during 3 to 6 hours and then remained within the subnormal limits 24 hours after the injection. The label incorporation from [1-14C] glycine into liver glycogen reached a maximum 6 to 24 hours after the hormone injection, coinciding in time with the maximum increase of the glycogen concentration in the liver. Hence, amino acids play a more important role in glycogen formation as compared with other precursors; thus they seem to be the main substrates in cortisol-induced gluconeogenesis. Cortisol produced no effect on [1,2-14C] glycerol oxidation, but the hormone increases oxidation of other labelled substrates involved in exhaled carbon dioxide.

Ceria, zirconia and mixed cerium-zirconium mesoporous oxides were synthesized and used as supports for sulfur and gold species. The materials were characterised using selected advanced techniques (ICP-OES, elemental analysis, XPS, XRD, N2 adsorption and desorption isotherms, UV-vis, ATR-FTIR, TPR-H2, TG-DTA) which allowed monitoring of the oxidation state of metals (cerium and gold) and the surface properties of the catalysts, in particular the concentration of the components on the surface and in the bulk of materials. The interactions between gold, sulfur and metals from oxides were considered. The goal of this work was studied the changes in the chemical composition of materials and the oxidation states of cerium species after the modification of oxides with sulfur and gold species and the estimation of the influence of these changes on the surface properties. The chemical composition of surface affects the mobility of surface oxygen and the oxidation state of cerium, which can play the role of redox sites (e.g. Ce3+/Ce4+ species), and therefore it strongly influences on the adsorption of hydrogen sulfide and then gold loading. Additionally, gold catalysts modified with sulfur species were tested in the reaction of glycerol oxidation in the liquid phase at basic conditions as the test reaction of the catalytic oxidation of organic pollutants from water.
