Biogenic Amine Analysis of Fresh and Stored Bluefish (Pomatomus Saltatrix) and Microbiological Survey of Histamine-Forming Bacte
Changes in histamine, putrescine, and cadaverine concentrations in fresh and stored bluefish (Pomatomus saltatrix) were determined using a new HPLC method. The HPLC method utilized a 5.0% (w/v) trichloroacetic acid (TCA) extraction, pre-column fluorescamine derivitization, and fluorescence …

Biogenic Amine Levels Correlate with Time of Day, Age, Light Cycle, and Aggressive State in the Flesh Fly, Sarcophaga crassipalpis
<p>The biogenic amines serotonin (5HT), dopamine (DA), and octopamine (OA) have been indicated in the regulation of behaviors, including aggression. The flesh fly, <em>Sarcophaga crassipalpis</em>, was used to investigate ontogenetic and circadian changes in amines and aggression. Heads of male …

Functional characterisation of aphid, Myzus persicae, nicotinic acetylcholine receptors and identification of a novel biogenic amine-gated ion channel from the honeybee, Apis mellifera
… revealed that the α5 nAChR responded to dopamine (EC50 3.37 μM), 5-hydroxytryptamine (EC50 122 μM), octopamine (EC50 378 μM), tyramine (EC50 91.1 μM) and histamine (EC50 3.36 mM) but not to GABA, glycine or glutamate. Dopamine, 5-hydroxytryptamine, octopamine and tyramine all acted as …

Genetic Functional Dissection of the Synaptic Output of a Dual-Function Integrating Neuron
… learning. RIM releases both glutamate and the biogenic amine tyramine (~noradrenaline) and forms gap junctions with neurons that govern various aspects of C. elegans locomotion. RIM is the major source of tyramine in C. elegans, and this output is known to extend reversal length of spontaneous …

Cell-selective modulation of the neuromuscular system in Drosophila
… main objective of my doctoral thesis was to examine the extent to which neuromodulator substances and their receptors modulate synaptic transmission at a cell-specific level using D. melanogaster. Using three different modulatory substances, i) octopamine - a biogenic amine released from motor …

Neural Mechanisms of Decision-Making: Modulation of the Feeding Neural Network by Nitric Oxide and Serotonin in the Predatory Marine Snail Pleurobranchaea Californica
… the signal molecule nitric oxide (NO) and the biogenic amine serotonin (5-HT), in regulating the activity within the feeding neural network in Pleurobranchaea californica, a predatory sea slug that makes stereotypic feeding and avoidance decisions based on its hunger state within the structure …

Indices of gut health and intestinal microbial ecology of the cat as affected by ingestion of select carbohydrates varying in fermentative capacity
… BCFA, ammonia, 4-methyl phenol, indole, and biogenic amine concentrations. Pectin also decreased crude protein and acid hydrolyzed fat digestibility, indicating that it may increase intestinal chyme viscosity and should be investigated further as a fermentable alternative to cellulose in …

Towards the Characterization of Enzymes Involved in the Metabolism of Tyrosine and Tyrosine Derivatives
… metabolism. We found nine potential arylalkylamine N-acetyltransferase (AANAT) genes in Ae. aegypti. Phylogenetic analysis suggests that these Ae. aegypti AANATs (AeAANATs) can be further divided into three clusters. Phylogenetic analysis suggests that insect AANATs may have different …

Neuropharmacological Properties of the Histaminergic System in the Zebrafish
Biogenic amine neurotransmitters are important modulators of the central nervous system. Studies on the roles of the histaminergic system have revealed that it regulates many key brain functions. It has also been implicated to be involved in many brain disorders. Modulation of histamine signalling …

Cells that Kill: The Chemosensory Cell Types of Aedes aegypti Mosquitoes
… cell types also express distinct profiles of biogenic amine, neuropeptide, and neurotransmitter receptors. This suggests the possibility that these sensory neurons are subject to local or top-down modulation that drives context- and state-relevant behaviors. We are now expanding on this work …

Molekulare und pharmakologische Charakterisierung von Serotonin-Rezeptoren der Honigbiene Apis mellifera
Die Honigbiene Apis mellifera gilt seit langem als Modell-Organismus zur Untersuchung von Lern- und Gedächtnisvorgängen sowie zum Studium des Sozialverhaltens und der Arbeitsteilung. Bei der Steuerung und Regulation dieser Verhaltensweisen spielt das Indolalkylamin Serotonin eine wesentliche Rolle. …

Studio della formazione di ammine biogene e di altri composti azotati negli alimenti
… qualitative and quantitative determination of biogenic amines (BA) and amino acids (AA), in particular the essential AA, in different food matrices typical of Sardinia (Italy). The study was focused on wines and table olives, which are potential source of biogenic amines due to their …
