Characterization of microbial populations in pilot-scale fluidized-bed reactors treating perchlorate- and nitrate-laden brine.

A salt-tolerant, perchlorate- and nitrate-reducing bacterial culture developed previously was used to inoculate two acetate-fed fluidized bed reactors (FBRs) which treated a 6% ion-exchange regenerant brine containing 500 +/- 84 mg-N/L nitrate and 4.6 +/- 0.6 mg/L perchlorate.

Prostate cancer of transition zone origin lacks TMPRSS2-ERG gene fusion.

Recent studies have shown a unique chromosomal rearrangement that leads to the fusion of 5'-transmembrane protein serine proteinase-2 (TMPRSS2) with the EST-related gene (ERG) in prostate cancer. In this study, we used fluorescence in situ hybridization to evaluate TMPRSS2-ERG gene fusion in prostate cancer of different zonal origins. Radical prostatectomy specimens with multifocal prostate cancer were obtained from 30 patients who were treated at our institution.
