A number of structurally related hydantoins has been examined for their effects on the metabolic activities of Ehrlieh aseites carcinoma cells. 5-Ethylsulfinylmethylhydantoin [ESH] was a potent inhibitor of such activities. 5-Ethylsulfonylmethylhydantoin had less activity, and the other hydantoins tested were without effect. ESH was also a potent inhibitor of metabolism in Salk "altered" monkey...

Thermostable enzymes find wide applications to basic studies concerning protein stability as well as to development of industrial and specialty bioprocesses. In the process for the production of optically pure D-amino acids, obtained from the corresponding hydantoin derivatives using a microbial D-hydantoinase,1 limited substrate solubility and enzyme stability were posed as problems. In this c...

DNA base-damage recognition in the base excision repair (BER) is a process operating on a wide variety of alkylated, oxidized and degraded bases. DNA glycosylases are the key enzymes which initiate the BER pathway by recognizing and excising the base damages guiding the damaged DNA through repair synthesis. We report here biochemical and structural evidence for the irreversible entrapment of DN...

Assortative mating in phenotype in human marriages has been widely observed. Using genome-wide genotype data from the Framingham Heart study (FHS; number of married couples = 989) and Health Retirement Survey (HRS; number of married couples = 3,474), this study investigates genomic assortative mating in human marriages. Two types of genomic marital correlations are calculated. The first is a co...

The purpose of this research was to study the neutralization efficacy of a universal neutralizer proposed by the CTPA on a range of antimicrobial agents and its potential toxicity for microorganisms that are used for antimicrobial preservation testing. Several types of antimicrobial agents including a mixture of methylisothiazolinone and its 5-chloro derivative, dimethylol dimethyl hydantoin, Q...
