  1. 16. Thermal physiology and metabolism : Interplay between heat generation and energy homeostasis

    Författare :Gustavo Abreu-Vieira; Jan Nedergaard; Eric Ravussin; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fysiologi; Physiology;

    Sammanfattning : Mammal metabolism is intimately connected to the maintenance of body temperature. While metabolic pathways invariably produce heat as a by-product, the natural heat present in the environment also plays a role in defining the adaptive metabolism and general physiology of an organism.

  3. 17. Cardiovascular regulation in women with vasovagal syncope : With special reference to the venous system

    Författare :Johan Skoog; Toste Länne; Marcus Lindenberger; Helene Zachrisson; Ola Eiken; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Although vasovagal syncope (VVS) is a common clinical condition the mechanisms behind VVS remain elusive. Upright posture is the major trigger of VVS and lower limb blood pooling affecting cardiac output has been proposed as a major determinant. The overall aim of this thesis was twofold. LÄS MER

  4. 18. Regulation of the myogenic response and stretch-induced calcium signaling in the vascular wall: Novel insights into the role of microRNAs and protein tyrosine kinase 2

    Författare :Anirban Bhattachariya; Kärlfysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; portal vein; resistance artery; myogenic tone; PYK2; calcium; microRNA;

    Sammanfattning : Intraluminal pressure has a significant impact on vascular adaptability, phenotype and regulation of blood flow and pressure. On one hand, increased pressure/stretch for a prolonged time can cause structural changes in vessel wall; on the other hand, lack of pressure/stretch can promote a phenotype shift. LÄS MER

  5. 19. Allopregnanolone effects on food intake and weight gain

    Författare :Ellinor Holmberg; Torbjörn Bäckström; Bo Söderpalm; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allopregnanolone; neurosteroid; GABA; GABAA receptor; food intake; weight gain; obesity; hyperphagia; diurnal rhythm; schedule feeding; high fat diet; electrophysiology; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Background Obesity is currently one of the major causes of ill health and it is clear that overeatingis the cause of obesity. However, the actions of many endogenous factors that contribute to overeating are still not well understood. LÄS MER

  7. 20. Physiology and Pharmacology of GABAA receptors: The Brakes in the Brain

    Författare :Catarina Lindquist; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Fysiologi; Ion channels; GABA; Inhibition;

    Sammanfattning : Inhibitory neurotransmission in the brain is mostly mediated by gamma-aminobutyric acid type A (GABAA) receptors. These receptors are involved in both phasic inhibition (point-to-point inhibition, synaptic transmission) and tonic inhibition (diffuse form of inhibition, brain homeostasis). LÄS MER
