The ability to measure sulfur compounds at trace levels is extremely important in the food, flavor, and beverage industries. Sulfur compounds, especially volatile ones, impact flavor and aroma both positively and negatively, although they are more often associated with off-flavors or odors. Interest concerning the measurement and speciation of sulfur compounds in the citrus industry is growing....

Background and objectives: Garlic (Allium sativum L.) oil has been introduced in Iranian traditional medicine (ITM) as an effective topical agent for urine dribbling. Additionally, the beneficial effects of garlic on prostatic proliferation have been revealed in recent studies. The purpose of this research was formulation of a topical ointment using garlic oil proposed by ITM and quality contro...

BACKGROUND AND OBJECTIVE Volatile sulfur compounds may be the main source of oral malodor. The aim of this study was to clarify the relationship between periodontal parameters and volatile sulfur compounds and to evaluate the improvement of several halitosis-related outcomes by tongue scraping, nonsurgical periodontal treatment (including oral hygiene instruction) and oral hygiene instruction/c...

Synechococcus, C-Phycocyanin, Sulfur Nutrition The cyanobacterium Synechococcus 6301 is able to use a lim ited number o f sulfur compounds as the only source o f sulfur supply such as sulfate, thiosulfate, thioacetic acid, mercaptoacetic acid, thioacetamide, L-cysteine and glutathione. Compounds containg thioether linkages such as methionin or S-methylcysteine and all compounds investigated so ...

(tetrahydrofuran) at 703C for 16 h. The ester residue is then converted to a 6,6-dideuteriohexose residue, the O-methyl ethers of which are easily distinguishable by GC-MS of the derived alditol acetates. An alternative to acid hydrolysis that is applicable to most polysaccharides and glycoconjugates, including those containing acid-labile residues or glycosidic linkages resistant to hydrolysis...

The o-palladated, chloro-bridged dimers [Pd{2-phenylpyridine(-H)}-μ-Cl]2 and [Pd{N,N-dimethylbenzylamine(-H)}-μ-Cl]2 react with cyanuric acid in the presence of base to afford closed, chiral cage-molecules in which 12 organo-Pd(II) centers, located in pairs at the vertices of an octahedron, are linked by four tetrahedrally arranged cyanurato(3-) ligands. Incomplete (Pd10) cages, having structur...
