RESUMEN
A new pentanuclear "cylinder"-like cobalt(ii) phenylsilsesquioxane [(PhSiO1.5)10(CoO)5(NaOH)] exhibits a slow relaxation of the magnetization and a high catalytic activity and stereoselectivity in the oxidation of alkanes and alcohols.
RESUMEN
Gas-liquid chromatography was used to estimate content of short-chain fatty acids (SCFA) in 25 patients with cholelithiasis, 32 patients with irritable colon syndrome and constipation (ICS) and 35 healthy subjects. It was found that SCFA absolute and relative concentration in the feces of cholelithiasis patients is abnormal indicating disturbance of microbiocenosis as shown by changes in functional activity of some anaerobes of the intestinal microflora participating in enterohepatic circulation of bile acids. Alterations of SCFA content in the serum of cholelithiasis patients may be related to steroids disbolism. The study of SCFA in the feces and peripheral blood serum from cholelithiasis patients is of diagnostic value.
