The Maillard reaction not only results in the formation of flavor compounds, but also harmful by-products, including infamous toxicant acrylamide. Dietary acrylamide cannot be eliminated, its levels foods can minimized. This review discusses mechanisms inhibition, effectiveness under varied conditions, and limitations sulfur-containing compounds: thiols, sulfites, thioethers, thiosulfinates. Th...

COLLINS, R. P. (University of Connecticut, Storrs), AND H. D. GAINES. Production of hydrogen sulfide by Streptomyces odorifer. Appl. Microbiol. 12:335-336. 1964.-By use of various trapping systems, as well as lead acetate papers, Streptomyces odorifer was shown to produce hydrogen sulfide. Other sulfur-containing compounds may be produced by S. odorifer, but the amounts obtained were too small ...

Cisplatin is commonly used in cancer therapy and yeast cells are also sensitive to this compound. We present a transcriptome analysis discriminating between RNA changes induced by cisplatin treatment, which are dependent on or independent of SKY1 function--a gene whose deletion increases resistance to the drug. Gene expression changes produced by addition of cisplatin to W303 and W303-Δsky1 cel...

The syntheses of novel tricyclic pyrrolo[2,3-d]pyrimidine analogues of S6-methylthioguanine are described. The crystal structures and pKa values of these and related O6-methylguanine analogues are reported. All compounds display higher pKa values than O6-methylguanine with the sulfur-containing analogues being the more basic and exhibiting higher stability in aqueous solution. In a standard sub...

We have studied the adsorption of elemental sulfur on TiO 2 (110) for exposure at room temperature and at 300°C. Depending on the substrate temperature we found different adsorption sites with scanning tunneling microscopy (STM). At room temperature sulfur adsorbs on the titanium rows with a high mobility along the [001] direction. At 300°C sulfur adsorbs at the position of the bridging oxygen ...
