Ractopamine HCl is a beta-adrenergic agonist (beta-agonist) recently approved by the U.S. Food and Drug Administration, but not other governmental agencies, for use in finishing swine. For these reasons, it was important to develop and validate mass

An important emerging issue in chemical carcinogenesis is the role that products of endogenous metabolism play in formation of covalently modified DNA. One example is the formation of α,β-unsaturated aldehydes as a result of endogenous and drug-sti

Heterocyclic aromatic amines (HAAs) are formed in cooked meats through pyrolysis reactions of different amino acids in the presence or absence of creatine/creatinine and sugars. HAAs are mutagens, colon/mammary gland carcinogens in rodents, and are s

Determination of fumonisins using on-line liquid chromatography coupled to electrospray mass spectrometry

Autor: Paul C. Howard, Steve Bajic, Steve W. Preece, Daniel R. Doerge, D. E. Games

Publikováno v: Rapid Communications in Mass Spectrometry. 8:603-606

Fumonisin (FB) mycotoxins are produced by Fusarium monoliforme, which grows primarily on yellow corn. Ingestion of FB1-contaminated food causes leukoencephalomalacia in horses, pulmonary edema in pigs, and is suspected in the etiology of human esopha
