  1. 1. Melatonin in the gastrointestinal tract

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Fanny Söderquist; Uppsala universitet.; [2019]
    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.

    Abstract : Major depressive disorder (MDD) is one of the leading global causes of disease burden. Worse yet, about one third of the patients with MDD do not experience a remission with current treatments. READ MORE

  3. 3. Development and Validation of Bioanalytical Methods Application to Melatonin and Selected Anti-Infective Drugs

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Susanne Römsing; Uppsala universitet.; Högskolan Dalarna.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Analytical Chemistry; Analytisk kemi; african trypanosomiasis; melatonin; malaria; antiretroviral drugs; lumefantrine; tafenoquine; lamivudine; nevirapine; zidovudine; sampling paper; dried blood spots; capillary blood; antimalarial drugs; solid-phase extraction; liquid chromatography;

    Abstract : This thesis describes bioanalytical methods for measuring melatonin and some anti-infective drugs in biological fluids. Solid-phase extraction (SPE) or protein precipitation was used for enrichment and purification of the analytes and Liquid Chromatography (LC) was used to analyze the samples. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Olivier Lepage; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; serotonin; brain; fish; rainbow trout; Oncorhynchus mykiss; feed; stress; cortisol; melatonin; behaviour; aggression; Biologi; NATURAL SCIENCES Biology; NATURVETENSKAP 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. 5. The Duodenal Mucosal Bicarbonate Secretion Role of Melatonin in Neurohumoral Control and Cellular Signaling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Markus Sjöblom; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; alkaline secretion; central nervous system; duodenal enterocyte; duodenal ulcer; duodenum; enterochromaffin cell; human; intraarterial; intracellular calcium; intracerebroventricular; melatonin; rat; vagal nerve; Fysiologi; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi;

    Abstract : The duodenal lumen is exposed to aggressive factors with a high potential to cause damage to the mucosa. Bicarbonate secretion by the duodenal mucosa is accepted as the primary important defense mechanism against the hydrochloric acid intermittently expelled from the stomach. READ MORE
