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
Tetsuji Yokoyama et al.
Alcoholism, clinical and experimental research, 29(4), 622-630 (2005-04-19)
Elevated mean corpuscular volume (MCV) is a traditional biological marker for alcohol abuse and alcoholism, but the underlying mechanism is unclear. Three recent epidemiologic studies consistently showed that MCV was elevated by alcohol drinking more markedly among individuals with genetically

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
Mercè Correa et al.
Neuroscience and biobehavioral reviews, 36(1), 404-430 (2011-08-10)
Mainly known for its more famous parent compound, ethanol, acetaldehyde was first studied in the 1940s, but then research interest in this compound waned. However, in the last two decades, research on acetaldehyde has seen a revitalized and uninterrupted interest.
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
