Chlordecone belongs to the class of persistent organochlorine pesticides that are remarkably resistant to environmental degradation. Even though their use was banned in the United States in 1978, these compounds can stil ...

Electron-biomolecule interactions are a biologically relevant field of study because there are several ion fragmentation techniques that have come to the forefront in mass spectrometric analysis that involve the intera ...

Agrobacterium tumefaciens is a gram-negative soil bacterium that causes crown gall tumors on dicotyledenous plants. The transferred DNA (T-DNA) portion of the A. tumefaciens tumor-inducing (Ti) plasmid enters infected ...

E. coli thioredoxin (TRX) was modified by the episulfonium ion derived from S-(2-chloroethyl)glutathione (CEG) or S-(2-chloroethyl)cysteine (CEC). The alkylation site was located at Cys-32, which was confirmed by tande ...

The challenges prompted by miniaturization of chromatographic systems have led scientists to explore new avenues in the synthesis of stationary phases. Packed capillary columns have found limited application in routine ...

The objective of this study was to further determine the distribution of selenoprotein W (SeW) in tissues from rats and sheep fed different selenium levels and to search for the possible functions of this protein. In t ...
