The charged quaternary ammonium compounds--methyl, ethyl and benzyl viologens--generate reactive oxygen species in photosynthetic cells. Three independent methyl viologen-resistant spontaneous mutants of Synechocystis sp. PCC 6803 were identified, in which the conserved R115 residue of the Slr1174 protein was replaced with G115, L115 and C115. The Slr1174(More)
The ratio between the normal (+) and null (0) alleles of the genes encoding glutatione S-transferases M1 (GSTM1) and T1 (GSTT1) were studied in normal individuals from northwestern Russia (control group) and in patients with bronchial asthma (BA). The frequency of the GSTM1 0/0 genotype in the population sample was statistically significantly lower (37.8%)(More)
The functional state of the myocardium was studied in 45 white Wistar rats in the early stages of chronic renal insufficiency. After resection of 4/6 of the renal parenchyma the initial stage of chronic renal insufficiency was created with the urea level in blood serum 7.0-10.0 mmol/l with normal content of electrolytes (duration of observation lasting 1.3(More)
107 patients were examined in different terms after vagotomy (up to 6 years) performed for ulcerous disease of the duodenum, 43 of them--prior to and after the operation. It is found that the suppression of the acid- and enzyme secretory function of the stomach is not related to the development of the mucosa atrophy, but it is conditioned by eliminating the(More)
