  2. 1. Melatonin in the gastrointestinal tract

    Author : Fanny Söderquist; Janet Cunningham; Annica Jacobson; Bodil Ohlsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; melatonin; MT1; MT2; gastointestinal tract; small intestinal neuroendocrine tumours; IBS; depression; anxiety; personality and affective disorder; Medicinsk vetenskap; Medical Science; Psychiatry; Psykiatri;

    Abstract : Melatonin is recognised as the pineal hormone regulating sleep and circadian rhythm. It has also been identified in peripheral tissues (mainly in animals) and thought to display a variety of actions, including anti-inflammatory properties, regulation of gastrointestinal (GI) functions, glucose homeostasis and beneficial effects in different tumour types.

  4. 2. Dietary L-Tryptophan Suppresses Aggression and Stress Responsiveness in Juvenile Rainbow Trout (Oncorhynchus mykiss) : The Role of Brain Serotonin and Plasma Melatonin

    Author : Olivier Lepage; Svante Winberg; József Haller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; serotonin; brain; fish; rainbow trout; Oncorhynchus mykiss; feed; stress; cortisol; melatonin; behaviour; aggression; Biologi; Biology; Biologi;

    Abstract : Juvenile rainbow trout (Oncorhynchus mykiss) fed L-tryptophan (TRP) supplemented feed for 7 days show a suppression of aggressive behaviour along with a reduction in post-stress plasma cortisol levels. However, 3 days of elevated dietary TRP does not have any effects on either aggressive behaviour or post-stress plasma cortisol levels. READ MORE

  5. 3. The optic tectum of the salmon:site of interaction of neurohormonal photoperiodic and neural visual signals. The GABAergic neuronal system and melatonin receptors

    Author : Marie Anzelius; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal anatomy; melatonin receptors; GABA; optic tectum; fish; brain; animal morphology; Djurs anatomi och morfologi;

    Abstract : Melatonin is a neurohormone which mediates photoperiodic signals from the pineal organ to the brain. GABA (g-aminobutyric acid) is the major inhibitory transmitter in the central nervous system. READ MORE

  6. 4. Melatonin receptors in pancreatic islets - Linking a genetic variant to functional phenotype

    Author : Cecilia Nagorny; Diabetes - molekylär metabolism; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Melatonin receptor; knock out mice; IVGTT; OGTT; ITT; Hyperinsulinemic clamp; MTNR1B; MT2;

    Abstract : Defective insulin secretion and insulin resistance are the two hallmarks of Type 2 Diabetes (T2D). The pathophysiology of the disease is not fully understood but genetic susceptibility for the disease is a new major player in the understanding of the underlying mechanisms. READ MORE

  7. 5. Regulation of Duodenal Mucosal Barrier Function and Motility : The Impact of Melatonin

    Author : Anna Sommansson; Markus Sjöblom; Olof Nylander; Oliver Bachmann; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; bicarbonate secretion; duodenum; enteric nervous system; enterochromaffin cell; ethanol; hexamethonium; in vivo; mecamylamine; motility; mucosal permeability; parecoxib; rat; Physiology; Fysiologi;

    Abstract : The duodenal mucosa is regularly exposed to acid, digestive enzymes and ingested noxious agents. It is thus critical to maintain a protective barrier to prevent the development of mucosal injury and inflammation, which are often observed in situations when barrier function is impaired. READ MORE
