		An agonist is any chemical substance which binds to the receptors of a NT and has the same effect as the NT.
		Biogenic amines use the second messenger system, and thus are capable of both modulatory/conditional and classical/unconditional effects, although the former actions are significantly more common with them.
		Biogenic amine transmitter actions depend on the receptors present, and each NT of this class is associated with its own receptor types.

	AIM
		The biogenic amine, histamine, is an endogenous compound.
		For example, on contact with, or ingestion of, a substance (antigen) to which an individual is ‘allergic’, histamine is released from mast cells and basophils as the antigen attaches to, and cross-links with, the IgE molecule (antibody) which is bound to the surface of the mast cell.
		Biogenic amines, including histamine, are primarily produced by both indigenous and commercial strains of lactic acid bacteria (LAB) in wine (Lonvaud-Funel and Joyeux 1994, Coton et al.

	UHH's Wind-Wave Tank: Sea Slicks and Their Chemical Properties
		For example, biogenic slicks are being secreted by plankton or by coral reefs thus causing quieter water conditions by damping dangerous water turbulence that might endanger delicate coral forms or crash plankton within the upper marine water surface.
		The chemical analysis of biogenic and man-made sea slicks suggested that typical characteristics are prevalent including the presence of a long alkyl chain (hydrophobic tail) and a polar head group (hydrophilic part).
		In line with this assumption, both the magnitudes of the radar backscatter damping ratios and the characteristics of the damping ratio/wavenumber curves were comparable for the PME slick spread from ethanol and for the biogenic slicks, while in the presence of the PME slick spread from n-hexane lower damping ratios were determined.

		The images showing natural (biogenic) surface slicks as well as man-made (anthropogenic) mineral oil spills were analyzed with the aim to study whether or not active radar techniques can be applied to discriminating between these two kinds of surface films.
		Controlled slick experiments were carried out during both shuttle missions in the German Bight of the North Sea as well as in the northern part of the Sea of Japan and the Kuroshio Stream region, where surface films of different viscoelastic properties were deployed within the swath of the shuttle radars.
		Furthermore, several SAR scenes from various parts of the world’s oceans showing radar signatures of biogenic as well as anthropogenic surface films at low to moderate wind speeds are analyzed.

		SIR-C/X-SAR images showing natural (biogenic) surface slicks as well as man-made (anthropogenic) mineral oil spills are analyzed with the aim to study whether active radar techniques can be applied to discriminate between these two kinds of surface films.
		From this data set it is shown that the damping behavior of the same substance (i.e., the reduction of the radar backscatter caused by the surface film) is strongly dependent on wind speed.
		It can be seen that biogenic (natural) surface slicks cause a strong damping at L band, whereas anthropogenic (mineral) oil spills cause only low L band damping ratios.

	Monoamine-oxidase inhibitors (Group PIM G025)
		Co-ingestion of other medications enhancing the availability of biogenic amines should be suspected and the diagnosis of the serotonin syndrome should be considered in the presence of three or more of the following symptoms: behavioural change (confusion or hypomania), agitation, myoclonus, hyperreflexia, sweating, shivering, tremor, diarrhoea, motor incoordination, muscle rigidity, fever.
		The increased availability of biogenic amines (such as noradrenaline and serotonin) is thought to be linked with the improvement in depression accounted for by IMAO treatment.
		In more severe intoxications or where there are other substances ingested, more aggressive measures such as establishment of an airway, ventilation, administration of intravenous fluids, control of seizures, and control of hyperthermia may be necessary.
