BECKMAN, ALEXANDER, AND EVELYN SATINOFF. Arousal from hibernation by intrahypothalamic injections of biogenic amines in ground squirrels. Am. J. Physiol. 222(4) : 875-879. 1972.--Injections of low doses of norepinephrine or 5-hydroxytryptamine into the preoptic and anterior area of the hypothalamus in hibernating ground squirrels (Citellus lateralis) initiated complete arousal from hibernation....

浦川 紀元 In the course of a systematic study on the constituents of amphibian skin active on vascular and extravascular plain muscle it soon became manifest that the skin of amphibians could represent an enormous store-house not only of biogenic amines (imida zole-, indole and phenyl-alkylamines) but also of highly active polypeptides. The most extensive investigation on this topic has so far been...

Natural and anthropogenic static electric fields are commonly found in the environment and can have both beneficial and harmful effects on many animals. Here, we asked how the fruitfly responds to these fields and what the consequences of exposure are on the levels of biogenic amines in the brain. When given a choice in a Y-tube bioassay Drosophila avoided electric fields, and the greater the f...

Chimera Biotec, founded in 2000 as a spin-off from academic research in Germany, has implemented its proprietary DNA-antibody conjugates within the highly innovative Imperacer product line, enabling the ultra-sensitive detection of proteins and other antigens. The ready-to-use, commercially available Imperacer kits offer a performance-enhancing tool to improve the limit of detection of conventi...

The genetics and neurobiology of Drosophila aggression are still poorly understood. A new study using an automated method to analyze one component of male fly aggression has shown that the biogenic amine octopamine plays a role in the modulation of aggressive behavior.

An effective biogenic approach is proposed to synthesize size-tunable CuO nanostructures using seed shell extract of Sapindus mukorossi plant use as efficient catalysts for conjugate addition amines acrylonitrile under ambient conditions.

copper amine oxidases (caos) catalyse the oxidative de-amination of biogenic amines which are ubiquitous compounds essential for cell growth and proliferation. the enzymes are homodimers containing both topaquinone and a cu(ii) ions as cofactors at the active site of each subunit. after extraction and purification of chickpea (cicer arietinum) amine oxidase by chromatoghraphy, km and vmax of th...

In the presence of a thiourea catalyst, β-CF3 nitroalkenes react with Hantzsch esters in a highly enantioselective fashion, giving a broad range of β-CF3 amine precursors with a tertiary stereocentre at the β-position. This reaction represents the first general catalytic enantioselective approach to this important class of β-CF3 amines.
