Acetaldehyde Production from Ethylene - Cost Analysis - Acetaldehyde E11A (2017)
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
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.
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
