Superoxide dismutase (SODs, superoxide oxidoreductase, E.C. 1.15.1.1.) activity has been estimated in red blood cells from patients suffering from liver cirrhosis and hepatocellular carcinoma. Erythrocytes supcroxide dismutase activity from patients with liver cirrhosis was found to be significantly higher than normal, while its activity was not significantly raised in patients with hepatocellu...

Two Gram-stain-positive, mycelium-forming actinobacteria (strains 14-Be-013T and 02-Gi-014) were isolated from walls colonized with moulds and studied taxonomically. The isolates formed yellowish-pigmented substrate mycelium showing no fragmentation. Comparative analysis of 16S rRNA gene sequences showed that these bacteria are most closely related to genera within the family Nocardiopsaceae, b...

A quadrupole gas analyzer system was calibrated for the gases H2, He, N2, 02, A, and Xe. The procedure involved first calibrating the system for argon, as the reference gas. This was done using conventional techniques. A mixture of the above gases was then introduced into the system to be calibrated. The system configuration was such that the ratio of the partial pressures of each of the test g...

Thermophysical properties of dense supercriiicai water with special emphasis on dielectric permittivity are discussed. Phase diagrams and some critical curves of the binary systems H20—H2, H2O—N, H20—02, H20-CH4 and H20-He to 450 °C and 200 MPa are shown. H20-He tas a type I critical curve. A rational equation of state to calculate phase diagrams and critical curves for polar—non polar systems ...

propene dissociation channels were characterized by ab initio ccsd(t)/6-311++g(d,p) calculations. inthis work the detailed mechanism of propene dissociation to c2h4+ch2, c2h2+h+ch3, c2h2+ch4 andc3h3+h2+h have been investigated. according to our calculations, ten fragments can be classified intofive dissociated channels. our results point out that two mechanisms come into play in the h2 eliminat...
