  1. 1. Blood Flow in Human Skeletal Muscle : The Effect of Adrenaline and the Influence of a Small Muscle Injury

    Författare :Torbjörn Vedung; Jan Henriksson; Jan Lundvall; Södersjukhuset Karolinska Institutet. Dept of Hand Surgery Dept of Physiology and Pharmacology; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenaline; blood flow; blood redistribution; ischemia; muscle injury; skeletal muscle; strain-gauge plethysmography; sympathetic tone; transmural pressure; 99mTechnetium clearance; tennis elbow; venous compliance; venous occlusion plethysmography; 133Xenon clearance; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; adrenaline;

    Sammanfattning : A variety of vasoregulatory systems are involved in the complex control of blood flow inhuman skeletal muscle. The interaction between these systems where one system canoverride or modify the other makes blood flow regulation complicated. LÄS MER

  2. 2. Platelet activation and aggregation: Clinical and experimental studies

    Författare :Sukhi Singh; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Platelet concentrate; Adrenaline; Noradrenaline; Ticagrelor; Platelet aggregation; Platelet activation;

    Sammanfattning : Background: Dual antiplatelet therapy with acetylsalicylic acid (ASA) and the adenosine diphosphate (ADP)-receptor antagonist ticagrelor increases the risk of bleeding complications during cardiac surgery. The overall aim of this thesis was to identify and evaluate current and potential methods to reduce and prevent bleeding complications in patients with ongoing antiplatelet therapy. LÄS MER

  3. 3. 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. 4. Neonatal resuscitation - studies in piglets

    Författare :Rikard Linnér; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Newborn resuscitation; birth asphyxia; cerebral oxygenation; adrenaline; noradrenaline; severe hypoventilation; surfactant; nebulisation; vibrating mesh nebuliser. CPAP; lung deposition; lung distribution.;

    Sammanfattning : Background and aims: “It’s best to start with air” states the current guidelines on the resuscitation of babies at birth. In a piglet model mimicking severe neonatal asphyxia and circulatory arrest, different aspects of resuscitation were investigated (studies I-III). LÄS MER

  5. 5. 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 :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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.
