A novel multilayer film electrode containing 12-tungstosilicate anions was achieved on the surface of gold electrode by alternating deposition of 12-tungstosilicate anions with 60% quaternized poly(4-vinylpyridine) based on electrostatic interaction. The chemically-modified electrode exhibits a high catalytic activity towards the electroreduction of molecular oxygen.

Clostridium difficile (C. difficile) is now the leading cause of nosocomial diarrhea in the USA, accounting for 30% of patients with antibiotic-associated diarrhea, 70% of those with antibiotic-associated colitis, and most cases of pseudomembranous colitis. The organism has evolved over the last 8 years to become more virulent and resistant to antimicrobials (NAP1/027 strain) causing a more severe form of the disease that has increased mortality and healthcare costs. While it is generally accepted that the problem results from the overuse of antibiotics, and in particular second and third generation cephalosporins, fluoroquinolones and macrolides, recent studies suggest that acid suppres-sion with proton pump inhibitors (PPIs) may be equally culpable. A further common, but less recognized, etiological factor is the prolonged use of elemental diets. Such diets are totally absorbed within the small intestine and therefore deprive the colonic microbiota of their source of nutrition, namely dietary fiber, fructose oligosaccharides, and resistant starch. The resultant suppression of colonic fermentation leads to suppression of the "good" bacteria, such as butyrate-producers (butyrate being essential for colonic mucosal health), and bifidobacteria and the creation of a "permissive" environment for C. difficile colonization and subsequent infection. Based on this analysis, the best chance of suppressing the emerging C. difficile epidemic is to adopt a 3-pronged attack consisting of (1) avoidance of the use of prophylactic antibiotics, (2) the avoidance of prophylactic PPIs, and (3) the conversion of elemental diet feeding to a diet containing adequate indigestible carbohydrate after the first week of critical illness. In this review, we highlight the rising worldwide incidence of C. difficile associated diarrhea and the role played by non-residue diets in destabilizing the colonic microbiota.

ENDOPLASMIC reticulum (ER) molecular chaperone glucose regulated protein (Grp94 ), a mem-ber of heat shock protein 90 family, is a relatively abundant luminal protein in the ER. Theexpression of the Grp94 gene is markedly increased under many stress conditions. Grp94 isprimarily involved in folding, assembly and translocation of proteins synthesized within

The hybridized state of each atom changes with various changes of alloying elements and different alloying degrees. It is shown that during the course of alloying, the changes in the microsolid_state reflection such as atomic hybridized state make the corresponding VES parameters change, and that affects the mechanical properties of Fe-3Al alloys.

Using electrode as laser cladding materials, the microstructure and wear resistance of laser clad layer of ductile cast iron was studied. The laser clad layer can be subdivided into the melted zone where existed large amounts of austenite, graphite nodules and some carbides, and the solid state transformation zone which included martensite and austenite below the melted zone. The Ti combined with C to form TiC increasing the wear resistance; The Co significantly increased the wear resistance compared with Ti.

The chromosomes 1, 3, 5, 6, 7,10 and 12 of rice field eel (Monopterus albus Zuiew) have been microdissected successfully from meiosis I diakinesis spreads by using glass microneedlc under an inverted microscope. And the DOP-PCR products of the single chromosome dotted on the nylon membrane as 'specific chromosomal DNA pool', have been hybridized with 6 probes to map these genes. The mapping results show that Zfa has been mapped to chromosome 1, rDNA to chromosomes 3 and 7, both Gh and Pdegγto chromosome 10, Hsl to chromosome 5 and Hox genes have been detected on chromosomes 1, 3, 6 and 10 meantime. It has initiatively been suggested that chromosome 10 of rice field eel might possess the commom conserved synteny to that on chromosome 17 of human, chromosome 11 of mouse, chromosome 12 of pig and chromosome 19 of bovine. And so chromosome 3 of rice field eel might also contain the commom conserved synteny to that on chromosome 2 of zebraf-ish. Our study is an attempt to establish a new and feasible
