Alpha spectroscopic analysis of actinides (Th, U and Pu) after separation from aqueous solutions by cation-exchange and liquid extraction
(2010)The radioactivity concentration of 236Pu, 232U and 228Th in aqueous samples has been determined by means of alpha spectroscopy after chemical separation and pre-concentration of the radionuclides by cation exchange and ...

Involvement of host DNA gyrase in growth of bacteriophage T5
(1986)Bacteriophage T5 did not grow at the nonpermissive temperature of 42°C in Escherichia coli carrying a temperature-sensitive mutation in gyrB [gyrB(Ts)], but it did grow in gyrA(Ts) mutants at 42°C. These findings indicate ...

Separation of the complexes formed between the regulatory and catalytic subunits of cyclic adenosine monophosphate-dependent protein kinase and topoisomerase I activity in preovulatory follicle-enriched immature rat ovaries
(1989)Our previous studies have shown that the regulatory subunits of the type II form of cAMP-dependent protein kinase (R‖) present in soluble extracts of immature rat ovaries elute from diethylaminoethyl-cellulose as three ...
