The effect of estradiol on phosphorylation with gamma-32P-ATP of ribosome proteins from polyribosome fraction, isolated from female rat liver is found out. Rats (180 g) used were: sham-operated, ...ovariectomized and treated after ovariectomy for 11 days with 20 micrograms 17 beta-estradiol-dipropionate per 100 g body weight. The estradiol deficiency after ovariectomy decreased phosphorylation, but the estrogenization of ovariectomized rats increases it twice. In vitro the hormone (1-2 mumol/l) corrected also stimulated ribosome protein phosphorylation. It is supposed that the hormone may take part in the regulation of protein synthesis in the translational region of the process.
The RPC muon detector of the CMS experiment at the LHC (CERN, Geneva, Switzerland) is equipped with a Gas Gain Monitoring (GGM) system. A report on the stability of the system during the 2011-2012 ...data taking run is given, as well as the observation of an effect which suggests a novel method for the monitoring of gas mixture composition.
