  2. 11. Gastrointestinal Permeability and Motility in Inflammatory Bowel Disease

    Author : Anas Kh. Al-Saffar; Per Hellström; Dominic-Luc Webb; Åsa Keita; Uppsala universitet; []
    Keywords : Gastrointestinal motility; intestinal permeability; Mucosal; Ghrelin; Medicinsk vetenskap; Medical Science;

    Abstract : Synchronized motility, permeability and secretory (hormones and enzymes) events are integral to normal physiology. Smooth muscle syncytium operates with enteric nervous system (ENS) and endocrine signalling to accommodate, mix and control passage of ingested materials. READ MORE

  4. 12. Pitfalls in β-cell ion imaging with fluorescent indicators and their use for real-time detection of somatostatin secretion

    Author : Mingyu Yang; Anders Tengholm; Enming Zhang; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; β-cells; cytoplasmic Ca²⁺; cytoplasmic pH; fluorescent indicators; pancreatic islets; R-GECO1; somatostatin; type 2 diabetes; Molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Fluorescent ion indicators have become indispensable tools in cell physiology. Dye indicators can easily be loaded into most types of cells, while genetically encoded indicators are advantageous in allowing specific cellular or subcellular targeting. READ MORE

  5. 13. Metabolic roles of adenosine : studies using genetically modified mice and transfected cells

    Author : Stina Johansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Adenosine; A1 receptor; adipocyte; pancreas; skeletal muscle; GHSR1a; caffeine; metabolism and knock out mouse;

    Abstract : The aim of this thesis was to further investigate the metabolic roles of adenosine. The endogenous nucleoside adenosine acts by binding to the four adenosine receptors, A1R, A2AR, A2BR and A3R. The A1R is the adenosine receptor that has been proposed to be the one most involved in metabolism. READ MORE

  6. 14. Alcohol and the effect on some appetite-regulating hormones in man

    Author : Jan Calissendorff; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Leptin; ghrelin; octanoylated; PYY3-36; GLP-1; obestatin; alcohol; NPY; IGF-1; IGFBP-1; insulin; glucose; testosterone; cortisol; catecholamines;

    Abstract : Beverage containing alcohol has been used for centuries to stimulate appetite. Ingestion of a moderate amount of alcohol increase energy intake. Regulation of food intake is complex. Several factors cooperate such as neural impulses from sensory organs; sight, smell, gut distension, social setting, memory, current energy status and hormones. READ MORE

  7. 15. The Gastrin-ECL Cell Axis. Functional Aspects

    Author : Maria Björkqvist; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Pharmacological sciences; Calcium channels; CCK receptor antagonists; Misoprostol; Galanin; Somatostatin; Pancreastatin; Histamine; VIP; Gastrin; PACAP;

    Abstract : The ECL cells constitute a prominent endocrine cell population in the acid-producing part of the stomach. They are controlled by circulating gastrin released from G-cells in the antrum. In response to gastrin, they secrete histamine, that in turn stimulates the parietal cell to secrete acid. READ MORE
