The presence and function of melatonin and structurally related indoleamines in a dinoflagellate, and a hypothesis on the evolutionary significance of these tryptophan metabolites in unicellulars.
Lowering intercellular melatonin levels by transgenic analysis of indoleamine 2, 3-dioxygenase from rice in tomato plants.

A significant decrease in retinal antioxidant defense was observed in a rat model mimicking human open-angle glaucoma and since melatonin ameliorated this process, the indoleamine may be a useful component of a therapeutic strategy in glaucoma .
The indoleamines were evaluated against butylated hydroxytoluene (BHT) which was chosen as a reference standard because of its high antioxidant capacity.

Post-hoc analysis of indoleamines in septic patients under selective extracorporeal immunoadsorption (IA) of LPS, IL6 and C5a
Non-parametric receiver operating characteristic analyses were applied to assess the predictive value of indoleamines regarding the development of sepsis during the ICU stay (positive event).
. After sonication of platelet-rich plasma to disrupt the platelets (Ultrasonic Liquid Processor, model 385; Heat Systems Ultrasonics Inc., Farmingdale, NY, U.S.A.), both platelet-rich and platelet-poor plasma were processed in the same way: 200[micro]l of 3.4 mol/L perchloric acid and 50 [micro]1 of 5-hydroxy-tryptophan solution (114.5 [micro]g/m1), as internal standard, were added to 1 ml of plasma vortexed and centrifuged at 10,000 rpm for 15 min at 4[degrees]C.
These enzymes are called L-tryptophan 2,3-dioxygenase (TDO) and indoleamine
(1) Both catecholamines and indoleamines
belong to the group of biogenic amines, which are organic compounds formed during biochemical processes in plants and animals that carry a nitrogen atom as a central molecule.
Little or no yellow fluorescence of indoleamines
(Furness et al., 1977) was noted in any of the aforementioned studies.
