Chemical and behavioral studies on dufour gland contents ofManica rubida (Hymenoptera: Formicidae).

Journal of chemical ecology

Jackson BD, Cammaerts MC, Morgan ED, Attygalle AB.
PMID: 24263598
J Chem Ecol. 1990 Mar;16(3):827-40. doi: 10.1007/BF01016493.

The Dufour gland ofManica rubida contains a simple mixture of (Z, E)-α-farnesene and (Z, E)-α-homofarnesene with tiny amounts of other faraesene, homofarnesene, and bishomofarnesene isomers. The gland also contains a mixture of very volatile compounds, chiefly acetone, with smaller...

The promotion of O2 adsorption on semiconductor surfaces for effectively capturing photogenerated electrons in the photocatalytic degradation of pollutants is highly desired. In this study, the targeted co-modification of residual chlorine rutile TiO2 nanorods with phosphoric and boric acids...

Remote chirality control based on the organocatalytic asymmetric Mannich reaction of α-thio acetaldehydes.

Chemical communications (Cambridge, England)

Kano T, Sakamoto R, Maruoka K.
PMID: 24305743
Chem Commun (Camb). 2014 Jan 28;50(8):942-4. doi: 10.1039/c3cc47827k.

Remote chirality control leading to 1,4-difunctionalized compounds such as 1,4-amino alcohols and 1,4-diamines was achieved by both syn- and anti-selective asymmetric Mannich reactions of α-thio acetaldehydes, the subsequent olefination and the stereospecific 2,3-sigmatropic rearrangement.

Synergistic reduction of toluylene blue induced by acetaldehyde and menadione in yeast cell suspension: Application to determination of yeast cell activity.

Biochem Biophys Rep. 2017 Feb 05;9:335-340. doi: 10.1016/j.bbrep.2017.01.015. eCollection 2017 Mar.

Membrane permeant acetaldehyde and menadione induced the synergistic reduction of toluylene blue (TB) acting as non-membrane permeant redox indicator in yeast cell suspension. NADH and acetaldehyde also induced the synergistic TB reduction in permeabilized yeast cells and phosphate buffer,...

Ethanol surface chemistry on MBE-grown GaN(0001), GaO.

The Journal of chemical physics

Kollmannsberger SL, Walenta CA, Winnerl A, Knoller F, Pereira RN, Tschurl M, Stutzmann M, Heiz U.
PMID: 28964022
J Chem Phys. 2017 Sep 28;147(12):124704. doi: 10.1063/1.4994141.

In this work, ethanol is used as a chemical probe to study the passivation of molecular beam epitaxy-grown GaN(0001) by surface oxidation. With a high degree of oxidation, no reaction from ethanol to acetaldehyde in temperature-programmed desorption experiments is...

Journal of the American Chemical Society

Liu Y, Zhao SF, Guo SX, Bond AM, Zhang J, Zhu G, Hill CL, Geletii YV.
PMID: 26848832
J Am Chem Soc. 2016 Mar 02;138(8):2617-28. doi: 10.1021/jacs.5b11408. Epub 2016 Feb 22.

Highly efficient electrocatalytic oxidation of ethanol and methanol has been achieved using the ruthenium-containing polyoxometalate molecular catalyst, [{Ru4O4(OH)2(H2O)4}(γ-SiW10O36)2](10-) ([1(γ-SiW10O36)2](10-)). Voltammetric studies with dissolved and surface-confined forms of [1(γ-SiW10O36)2](10-) suggest that the oxidized forms of 1 can act as active...

Ethanol metabolism, toxicity and genetic polymorphism.

Addiction biology

Iwahashi K, Suwaki H.
PMID: 26734919
Addict Biol. 1998 Jul;3(3):249-59. doi: 10.1080/13556219872065.

The relationships between the individual (and racial) differences in alcohol metabolism and toxicity, and the genetic polymorphism of alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ALDH), and cytochrome P-4502E1(CYPIIE1) were reviewed. In recent studies involving DNA analysis, it was found that...

Molecularly Imprinted Polymer Nanoparticles for Formaldehyde Sensing with QCM.

Sensors (Basel, Switzerland)

Sensors (Basel). 2016 Jun 30;16(7). doi: 10.3390/s16071011.

Herein, we report on molecularly imprinted polymers (MIPs) for detecting formaldehyde vapors in air streams. A copolymer thin film consisting of styrene, methacrylic acid, and ethylene glycol dimethacrylate on quartz crystal microbalance (QCM) yielded a detection limit of 500...

Aggregation pheromone of driedfruit beetle,Carpophilus hemipterus Wind-tunnel bioassay and identification of two novel tetraene hydrocarbons.

Journal of chemical ecology

Bartelt RJ, Dowd PF, Plattner RD, Weisleder D.
PMID: 24263709

For two decades, the aggregation pheromone of the boll weevil,Anthonomus grandis Boh. (Coleoptera: Curculionidae), was thought to consist of four compounds: I [(+)-(Z)-2-isopropenyl-1-methylcyclobutane ethanol]; II [(Z)-3,3-dimethyl-Δ(I,β)-cyclohexane ethanol]; III [(Z)-3,3-dimethyl-Δ(1,α)-cyclohexane acetaldehyde); and IV [(E)-3,3-dimethyl-Δ(1,α)-cyclohexane acetaldehyde). Evidence is presented from behavioral...

Gut Pathog. 2013 Jun 24;5(1):16. doi: 10.1186/1757-4749-5-16.

BACKGROUND: Listeria adhesion protein (Lap), an alcohol acetaldehyde dehydrogenase (lmo1634) promotes bacterial paracellular translocation through epithelial cell junctions during gastrointestinal phase of infection. Secreted Lap is critical for pathogenesis and is mediated by SecA2 system; however, if strain dependent...
