  1. 1. Experimental Disruption of Intestinal Mucosal Homeostasis : Exploring the Protective Potential of Melatonin and Misoprostol

    Författare :Karsten Peters; Markus Sjöblom; Hans Lennernäs; David Dahlgren; Åsa Keita; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intestinal barrier dysfunction; intestinal permeability; chemotherapy-induced mucositis; doxorubicin; 5-fluorouracil; apoptosis; proliferation; melatonin; misoprostol; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The intestinal mucosa serves as a protective layer that separates the intestinal contents from the underlying tissues. It restricts harmful substances, pathogens, and undigested particles from entering the bloodstream. LÄS MER

  3. 2. Melatonin receptors in pancreatic islets - Linking a genetic variant to functional phenotype

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

    Sammanfattning : 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. LÄS MER

  4. 3. Regulation of Duodenal Mucosal Barrier Function and Motility : The Impact of Melatonin

    Författare :Anna Sommansson; Markus Sjöblom; Olof Nylander; Oliver Bachmann; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. New pharmacological aspects of melatonin

    Författare :Lena G. E. Mårtensson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Melatonin is a hormone that takes part in the regulation of biological rhythms. It is produced in the pineal gland and is stimulated by darkness and inhibited by exposure to light. LÄS MER

  7. 5. Signaling for color change in melanophores : and a biosensor application

    Författare :Annika M. Karlsson; Samuel Svensson; Margareta Wallin; Linköpings universitet; []
    Nyckelord :color change; melanophores; tyrosine; phosphorylations; melatonin; nitric oxide; MEDICINE; MEDICIN;

    Sammanfattning : Melanophores are dark brown pigment cells located in the skin of fish, amphibia, reptiles, and many invertebrates. The color of the animal can change via rearrangement of pigment granules, melanosomes, in the cells. The dark melanophores can either hide colorful cells so that the animal appears dark, or let through colors from underneath. LÄS MER
