Sulfite species enhance carbon monoxide release from CO-releasing molecules: implications for the deoxymyoglobin assay of activity.
Anal. Biochem. 427(1) , 36-40, (2012) Carbon monoxide-releasing molecules (CO-RMs) emulate the beneficial (e.g., anti-inflammatory) effects of CO in biology. CO release from CO-RMs is routinely determined in the presence of reduced deoxy-myoglobin by measuring the formation of carboxy-myoglobin (... |

Improved synthesis of 2,2'-bipyrimidine.
J. Org. Chem. 67(18) , 6550-2, (2002) A high-yield synthesis was developed for the preparation of 2,2'-bipyrimidine (1) using the Ullmann coupling of 2-iodopyrimidine. The new procedure was also used for the preparation of 4,4',6,6'-tetramethyl-2,2'-bipyrimidine (2) and 5,5'-dibromo-2,2'-bipyrimi... |

Yeast ecology of vineyards within Marsala wine area (western Sicily) in two consecutive vintages and selection of autochthonous Saccharomyces cerevisiae strains.
J. Biosci. Bioeng. 114(6) , 606-14, (2012) In this work, the yeast ecology associated with the spontaneous fermentation of Grillo cultivar grapes from 10 vineyards was analyzed from grape harvest till complete consumption of must sugars. The microbiological investigation started with the plate count o... |

Aflatoxin in betel nut and its control by use of food preservatives.
Food Addit. Contam. 8(6) , 707-12, (1991) The occurrence of aflatoxins in market betel nut samples was studied. It was observed that several betel nut samples were infested with aflatoxin-producing fungus, Aspergillus flavus. Out of 32 samples collected from various places, 12 were positive for aflat... |

Growth inhibitory effect of grape phenolics against wine spoilage yeasts and acetic acid bacteria.
Int. J. Food Microbiol. 161(3) , 209-13, (2013) This paper investigates the in vitro antimicrobial potential of 15 grape phenolic compounds of various chemical classes (phenolic acids, stilbenes and flavonoids) using the broth microdilution method against yeasts and acetic acid bacteria frequently occurrin... |

Precipitating factors in asthma. Aspirin, sulfites, and other drugs and chemicals.
Chest 87(1 Suppl) , 50S-54S, (1985) Several types of reactions to drugs and chemicals may precipitate or perpetuate asthmatic relapse. This review focuses on reactions to aspirin and sulfites. Approximately 40 percent of patients with rhinosinusitis, nasal polyps, and asthma and 5 to 10 percent... |

Propionic acid-metabisulphite-Schiff reagent for quick Feulgen staining.
Microsc. Acta 84(3) , 245-8, (1981) This communication presents a method for the preparation of Schiff reagent in which N hydrochloric acid has been replaced by a low concentration of propionic acid. The result of using such a Schiff reagent indicates that the dye-reagent thus prepared is extra... |

Selective removal of the violet color produced by anthocyanins in procyanidin-rich unfermented cocoa extracts.
J. Food Sci. 76(7) , C1010-7, (2011) Cacao (Theobroma cacao L.) is rich in procyanidins, a large portion of which degrades during the natural fermentation process of producing cocoa powder. Recent advances in technology have enabled scientists to produce unfermented cocoa powder, preserving the ... |
