A nucleoside kinase has been purified about 1680-fold from L1210 leukemia cells with deoxyadenosine as the phosphate acceptor and with adenosine triphosphate as phosphate donor. The molecular weight of the enzyme, determined by Sephadex G-200 column chromatography, was found to be about 100,000. Purified enzyme, after the final step of purification and also after disc gel electrophoresis (Rf 0....

The conformation of d(TA)3 (CG)3 has been studied in aqueous solution in the presence of high salt concentration. The oligonucleotide forms in solution concatamers. In the presence of 5 M NaC1 the concatamer is built up of d(CG)3 blocks in Z-conformation and of d(TA)3 blocks in B-conformation. In the presence of 4 M LiCl both blocks in the concatamer display a B-type structure.

A long term pilot scale experiment with steam reforming treatment technology was conducted for volume and weight reduction of uranium contaminated waste tri-n-butyl phosphate/n-dodecane solvent (TBP/dodecane) which was difficult to incinerate. The technology consists of a steam reforming process and a submerged combustion process. In the first process, TBP/dodecane is vaporized and pyrolyzed wi...

phosphorus solubilizing microorganisms are capable of transforming insoluble phosphorus (p) forms to soluble and bioavailable p. the aim of the present study was to isolate p solubilizing bacteria from forest soils around the rock phosphate (rp) mine of koh-e-sepidlar in kohgiluyeh and boyer ahmad province and evaluate their ability in sperber culture medium and wheat straw medium in the presen...

This study uses industrial pollution data from the Environmental Protection Agency's Toxics Release Inventory (TRI) and tract-level demographic data from the 2000 U.S. census to determine whether environmental racial inequality existed in the Detroit metropolitan area in the year 2000. This study differs from prior environmental inequality research in two important ways. First, it offers a posi...

An SN2 reaction (NaI) of 1,7-di(methanesulfoxyl)heptadien-4-yl methoxy-(2-naphthyl)acetate and a tributyltin hydride reduction of 1,7-diiodo-4-yl methoxy-(2-naphthyl)acetate (2NMA) is crucial for determination of the absolute configuration of secondary alcohols.
