Marjie L Hard et al.
Placenta, 24(2-3), 149-154 (2003-02-05)
Significant interindividual variability exists following maternal alcohol consumption; not all children born to alcoholic women manifest the symptoms associated with foetal alcohol spectrum disorder (FASD). To investigate the potential role of the placenta as a source of variability by determining
Keitaro Matsuo et al.
Carcinogenesis, 34(7), 1510-1515 (2013-03-05)
The impact of alcohol on the risk of stomach cancer is controversial. Although aldehyde dehydrogenase 2 (ALDH2) Glu504Lys (rs671) polymorphism has a strong effect on acetaldehyde metabolism, little is known about its impact on stomach cancer risk when combined with

Alcohol (Fayetteville, N.Y.), 41(7), 469-478 (2007-11-06)
Recent introduction of several commercial Kudzu root (Pueraria lobata) containing hangover remedies has occurred in western countries. The available data is reviewed to assess if there are any potential concerns in relationship to the development of neoplasm if these products
M Becker et al.
Journal of chromatography. A, 1281, 115-126 (2013-02-13)
Gas chromatographic analysis of complex carbohydrate mixtures requires highly effective and reliable derivatisation strategies for successful separation, identification, and quantitation of all constituents. Different single-step (per-trimethylsilylation, isopropylidenation) and two-step approaches (ethoximation-trimethylsilylation, ethoximation-trifluoroacetylation, benzoximation-trimethylsilylation, benzoximation-trifluoroacetylation) have been comprehensively studied with regard
Dirk W Lachenmeier et al.
Addiction (Abingdon, England), 104(4), 533-550 (2009-04-02)
In addition to being produced in ethanol metabolism, acetaldehyde occurs naturally in alcoholic beverages. Limited epidemiological evidence points to acetaldehyde as an independent risk factor for cancer during alcohol consumption, in addition to the effects of ethanol. This study aims
