Thioredoxin (Trx), a small redox protein, controls multiple processes in eukaryotes and bacteria by changing the thiol redox status of selected proteins. The function of Trx in archaea is, however, unexplored. To help fill this gap, we have investigated this aspect in methanarchaea--strict anaerobes that produce methane, a fuel and greenhouse gas.

This genome from a bird harvested during the non-migratory season is the REFSEQ and the haplotype is designated GCC-A. There are two rRNAs, 22 tRNAs, 13 protein-coding regions, and 1 displacement loop region.

Study Design And Methods: Patients, aged 0 to 17 years, needing a first collection of PBSCs for autologous stem cell transplantation were eligible.
Background: ST1959 is a 3,5-diaryl-s-triazole belonging to a novel class of contragestional agents with immunosuppressant activity. The aim of the present study was to investigate the effects of this drug on allogeneic immune response and on renal allograft survival in rats.
Methods: One group of naive and one group of allosensitized Lewis rats received ST1959 (0.
