1. 6. The regulation of muscle interstitial insulin, nutrients and blood flow in insulin resistant models. An investigation using the euglycemic insulin clamp and microdialysis techniques

   Författare :Maria Niklasson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insulin resistance; skeletal muscle; glucose uptake; transcapillary transport; interstitial fluid; euglycemic insulinclamp; microdialysis; blood flow; vasodilation;

   Sammanfattning : Insulin resistance, mainly located to the skeletal muscle tissue, is one prominent feature in thedevelopment of non insulin-dependent diabetes mellitus (NIDDM) and further, associated withcardiovascular diseases. In this context the importance of blood flow for insulin sensitivity has beensuggested by regulating the delivery of insulin and nutrients to the target cells. LÄS MER

3. 7. Vasodilator actions of EDHF and anandamide

   Författare :David Andersson; Avdelningen för klinisk kemi och farmakologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vanilloid receptors; afferent neurons; anandamide; cannabinoids; potassium channels; hyperpolarization; vasodilation; Vascular endothelium; arteries; airways; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

   Sammanfattning : Vasodilator responses to endothelium-derived hyperpolarizing factor (EDHF) and anandamide in isolated arteries were investigated. A combination of the potassium channel blockers charybdotoxin and apamin inhibits EDHF-mediated relaxations. LÄS MER

4. 8. Regional oxygenation in cardiac surgery. Influence of temperature, pump flow and insulin

   Författare :Lena Lindholm; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiopulmonary bypass; cardiac surgery; regional oxygenation; venous oxygenation; splanchnic oxygenation; insulin; vasodilation; temperature; pump flow;

   Sammanfattning : Surgical trauma triggers neural, endocrine and inflammatory reactions with subsequent alterations in systemic and regional blood flow, blood pressure and metabolism. These changes are detectable after all major surgical procedures but are often more pronounced after cardiac surgery, probably because of blood exposure to artificial surfaces of the heart lung machine, temperature modulation (e.

5. 9. Endogenous activators of the pain receptor TRPV1 From cell to man

   Författare :Pouya Movahed Rad; Avdelningen för klinisk kemi och farmakologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; cannabinoids; capsazepine; N-acylethanolamines; anandamide; blood Circulation; vasodilation; humans; calcitonin Gene-related Peptide; capsaicin; neurogenic inflammation; nociceptors; TRPV1 protein; pain;

   Sammanfattning : N-acylethanolamines (NAEs) belong to a growing family of endogenous signalling molecules acting on a variety of receptors and ion channels. In 1992, it was reported that the N-acylethanolamine anandamide is present in the brain and activates the central cannabinoid (CB) receptor. LÄS MER

7. 10. Mental Stress and Endothelium-Dependent Vasodilation

   Författare :Kristina Johansson; Sverker Jern; Uppsala universitet; []
   Nyckelord :Medical sciences; Mental stress; endothelium; adrenoceptor blockade; catecholamine; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

   Sammanfattning : The endothelium plays an important part in blood flow regulation by producing the vasodilatory substance nitric oxide (NO). Various studies have shown that commonly accepted risk factors for coronary heart disease, such as hypertension, diabetes, hypercholesterolemia, smoking and mental stress impair endothelium-derived vasodilation by the NO-pathway.
