The recent introduction of the phenyl-beta-D-galactopyranoside (P-gal)-based positive-selection system for screening of lambda lacZ phages originating from the lambda lacZ transgenic mouse (Muta Mouse) has made the determination of mutant frequencies (MF) a much simpler task. Previously, MF data from

Substances that potentially enhance performance (eg, recombinant human erythropoietin [rHuEPO]) are considered doping and are therefore forbidden in sports; however, the scientific evidence behind doping is frequently weak. We aimed to determine the effects of rHuEPO treatment in well trained

8-Oxo-7,8-dihydro-2'-deoxyguanosine 5'-triphosphate (8-oxo-dGTP) is produced during normal cellular metabolism, and incorporation into DNA causes transversion mutation. Organisms possess an enzyme, 8-oxo-dGTPase, which catalyzes the hydrolysis of 8-oxo-dGTP to the corresponding nucleoside monophosphate, thereby preventing the occurrence of mutation. There are

Porcine submaxillary beta-galactoside alpha(1----2)-fucosyltransferase is known to transfer a fucosyl residue from guanosine 5'-diphosphofucose (GDP-fucose) to the 2-OH group of beta-D-galactopyranosides with inversion of configuration at the fucopyranosyl anomeric carbon. A bisubstrate analog (1) of the postulated transition-state for this

The gastrointestinal absorption of bisphosphonates is in general only about 1%. To address this problem mixtures of risedronate monosodium salt with twelve varied sugar alcohols, furanoses, pyranoses and eight gluco-, manno- and galactopyranoside derivatives as counterions were designed in an
