  1. 11. Roux-en-Y gastric bypass - clinical outcome and mechanisms of action

    Författare :Malin Werling; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Roux-en-Y gastric bypass; Obesity; Bariatric surgery; Energy chamber; Gastrointestinal hormones; GLP-1; PYY; Ghrelin; Energy expenditure; Body composition; Vertical Banded Gastroplasty; Indirect calorimetry; Overweight treatment; Weight loss;

    Sammanfattning : Roux-en-Y gastric bypass (gastric bypass) is an effective surgical technique for treating morbid obesity. The objective of this thesis is to increase knowledge of long-term outcomes of gastric bypass surgery and to elucidate some of the associated mechanisms of action. LÄS MER

  3. 12. Regulation of glucagon secretion from pancreatic alpha cells

    Författare :Yang De Marinis; diabetes och endokrinologi Genomik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epac2; glucagon secretion; pancreatic alpha cells; K- ATP channel; N-type Ca2 channel; L-type Ca2 channel; GLP-1; cAMP; PKA; Adrenaline; PKC;

    Sammanfattning : Glucagon secreted by pancreatic α-cells plays an important role in the regulation of blood glucose. In this thesis, different techniques such as electrophysiology, immunohistochemistry and hormone secretion assay were combined to explore the mechanisms by which glucagon secretion is regulated.

  4. 13. Pathophysiology and treatment of defective insulin secretion in diabetes

    Författare :Anders Rosengren; Diabetes - öpatofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic beta-cells; stem cells; genetics; exocytosis; Adra2a; PACAP; GLP-1; Physiology; Fysiologi; secreting systems; Endocrinology; diabetology; Endokrinologi; insulin secretion; Diabetes mellitus; sekretion; diabetologi;

    Sammanfattning : Defective insulin secretion is a central feature in diabetes mellitus and results from reduced pancreatic beta-cell mass as well as aberrant beta-cell function. The pathophysiology of diabetes is incompletely known, but a strong hereditary component is suggested. LÄS MER

  5. 14. Childhood Obesity and Islet Function

    Författare :Johan Staaf; Peter Bergsten; Anders Forslund; Hindrik Mulder; Uppsala universitet; []
    Nyckelord :type 2 diabetes mellitus; Uppsala Longitudinal Study of Childhood Obesity; palmitate; glucose-stimulated insulin secretion; hyperinsulinemia; hyperglucagonemia; GLP-1; glicentin; magnetic resonance imaging; metabolic syndrome; oral glucose tolerance test; centroid; Pediatrik; Pediatrics;

    Sammanfattning : The prevalence of childhood obesity and Type 2 Diabetes Mellitus (T2DM) has increased during recent decades. T2DM is accompanied with functional changes in the islets of Langerhans, which can be identified early in the pathogenesis. LÄS MER

  7. 15. On the Generation of cAMP Oscillations and Regulation of the Ca2+ Store-operated Pathway in Pancreatic Islet α- and β-cells

    Författare :Geng Tian; Erik Gylfe; Anders Tengholm; Patrick Gilon; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cAMP; oscillations; adrenaline; GLP-1; phosphodiesterase; palmitate; STIM1; Orai1; store-operated calcium entry; insulin secretion; glucagon secretion; β-cell; α-cell; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Insulin and glucagon are released in pulses from pancreatic β- and α-cells, respectively. Both cell types are electrically excitable, and elevation of the cytoplasmic Ca2+ concentration ([Ca2+]i) due to depolarization with voltage-dependent entry of the cation is the main trigger of hormone secretion.
