Recovery from N -Hydroxyurethan-Induced Death

Recovery from N-hydroxyurethan-induced death.

Bacteria (Escherichia coli) can recover from the lethal action of N-hydroxyurethan when they are incubated in drug-free liquid medium. This recovery, which is dependent upon energy metabolism, does not occur on solid medium. Recovery is accompanied by repair of the cellular deoxyribonucleic acid (DNA). A bacterial mutant deficient in DNA polymerase was extremely sensitive to the lethal action o...

Palladium(II) Recovery from Hydrochloric Acid Solutions by N,N′-Dimethyl-N,N′-Dibutylthiodiglycolamide

N,N′-dimethyl-N,N′-dibutylthiodiglycolamide (DMDBTDGA) has been synthesized, characterized, and is investigated in this work as a potential liquid-liquid extractant for palladium(II), platinum(IV), and rhodium(III) from hydrochloric acid solutions. Pd(II) is the only ion which is efficiently removed by DMDBTDGA in toluene from 1.5 M to 4.5 M HCl, but it is not extracted from 7.5 M HCl. Pd(II) s...

N-acetyl cysteine protects cells from chondrocyte death induced by local anesthetics.

Local anesthetics (LA) are among the drugs most frequently used for musculoskeletal problems, in procedures ranging from diagnosis to postoperative pain control. Chondrocyte toxicity induced by LA is an emerging area of concern. The purpose of this study was to determine whether N-acetyl cysteine (NAC), an antioxidant, will exert cytoprotective effects against chondrocyte death induced by LA. P...
