Poultry processing antimicrobial interventions are critical for pathogen control, and organic, mobile operations in Washington seek alternatives to chlorine. Laboratory and field studies (three replications each) evaluated lactic acid efficacy as a chlorine alternative. For the laboratory study, retail-purchased, conventionally processed chicken wings inoculated with Salmonella were randomly assigned to ...

MDM2 is the most important negative regulator of tumor suppressor p53. Both RING finger domain and acidic domain of MDM2 contribute to the ubiquitination of p53. The crosstalk between ubiquitination and acetylation of p53 prompts us to examine whether acidic domain is essential for MDM2 to regulate the acetylation of ...

Branched core/shell bismuth telluride/bismuth sulfide nanorod heterostructures are prepared by using a biomimetic surfactant, L-glutathionic acid. Trigonal nanocrystals of bismuth telluride are encapsulated by nanoscopic shells of orthorhombic bismuth sulfide. Crystallographic twinning causes shell branching. Such heteronanostructures are attractive for thermoelectric power generation and cooling applications.

Biotransformation of chrysin by Cunninghamella elegans NRRL 1392 produced apigenin, apigenin 7-sulfate, apigenin 7,4'-disulfate, and a new metabolite identified as chrysin 7-sulfate. On the other hand, fermentation of apigenin, using the same microorganism, yielded apigenin 7-sulfate and apigenin 7,4'-disulfate. The structures of the metabolites were established by spectral analysis, and ...
