The incidence of Escherichia coli having pathogenic genes for diarrhea was studied in Laos in 2002. A total of 525 E. coli strains from 278 patients (basically, two E. coli isolates from each patient) were examined by PCR to detect the known pathogenic genes (stx, eae, elt, est, ipaH, and aggR). These genes were detected in 23 strains from 16 patients (16/278: 5.8%). In 10 cases of the 16, one ...

Staggered InGaN quantum wells (QWs) are investigated both numerically and experimentally as improved active region for light-emitting diodes (LEDs) emitting at 520–525 nm. Based on a self-consistent six-band k.p method, band structures of both two-layer staggered InxGa12xN/InyGa12yN QW and three-layer staggered InyGa12yN/InxGa12xN/InyGa12yN QW structures are investigated as active region to enh...

Clostridium perfringens TpeL belongs to a family of large clostridial cytotoxins that encompasses Clostridium difficile toxin A (TcdA) and B (TcdB) and Clostridium sordellii lethal toxin (TcsL). We report here the identification of the TpeL-catalyzed modification of small GTPases. A recombinant protein (TpeL1-525) derived from the TpeL N-terminal catalytic domain in the presence of streptolysin...

The basic properties of estradiol 2-hydroxylase in rat brain microsomes were studied and compared to the known characteristics of rat liver microsomal estradiol 2-hydroxylase. Rat liver microsomal estradiol 2-hydroxylase, which has been considered to be a cytochrome P450-like enzyme, was largely inhibited by carbon monoxide. On the other hand, the effect of carbon monoxide on the activity of ra...

In this paper the challenge of parallelization development of industrial high performance inspection systems is addressed concerning a conventional parallelization approach versus an auto-parallelized technique. Therefore, we introduce the functional array processing language Single Assignment C (SaC), which relies on a hardware virtualization concept for automated, parallel machine code genera...

Optimizing compilers have become an essential component in achieving high levels of performance. Various simple and sophisticated optimizations are implemented at different stages of compilation to yield significant improvements, but little work has been done in characterizing the effectiveness of optimizers, or in understanding where most of this improvement comes from. In this paper we study ...
