2-[(R)-2-Hydroxypropylthio]ethanesulfonate (R-HPC) dehydrogenase (DH) catalyzes the reversible oxidation of R-HPC to 2-(2-ketopropylthio)ethanesulfonate (2-KPC) in a key reaction in the bacterial conversion of chiral epoxides to beta-keto acids. R-HPCDH is highly specific for the R-enantiomer of HPC, while a separate enzyme, S-HPCDH, catalyzes the oxidation of the corresponding S-enantiomer. In...

The 5' terminus of the Cyl actin gene transcription unit of Strongylocentrotus purpuratus was located by primer extension and other procedures, and the flanking upstream region was partially sequenced and mapped. A fusion gene was constructed containing about 2-5 kb of 5' flanking sequence, the transcribed leader sequence, and the first few codons of the Cyl gene ligated to the bacterial gene c...

We consider a cocompact discrete reflection group W of a CAT(0) space X . Then W becomes a Coxeter group. In this paper, we study an analogy between the Davis-Moussong complex Σ(W, S) and the CAT(0) space X , and show several analogous results about the limit set of a parabolic subgroup of the Coxeter group W .

Objective: Lately, the spiritual and religious (S/R) aspect of health behave has been receiving an increased attention in the scientific literature. The study aims to show the components of R/ S coping in cases of cancer in Iran. Method: The design of the current research is according to a qualitative research using content analysis. Sixteen patients with various kinds of cancer take part in th...

Research on personality’s role in coping is inconclusive. Proactive coping ability is one’s tendency to expect and prepare for life’s challenges (Schwarzer & Taubert, 2002). This type of coping provides a refreshing conceptualization of coping that allows an examination of personality’s role in coping that transcends the current situational versus dispositional coping conundrum. Participants (N...
