  2. 6. Local Purinergic Control of Arteriolar Reactivity in Pancreatic Islets and Renal Glomeruli

    Author : Xiang Gao; Leif Jansson; Olle Hellberg; Uppsala universitet; []
    Keywords : afferent arteriole; islet arteriole; adenosine; A1 receptor; ATP; P2Y receptor; microperfusion; angiotensin II; type 2 diabetes; hypertension; oxidative stress; nitric oxide; tubuloglomerular feedback;

    Abstract : Local control of regional blood flow is exerted mainly through the arterioles. An adequate minute-to-minute regulation of blood perfusion of the kidney and the pancreas is obtained by the modulation of arteriolar reactivity, which will influence the organ function. READ MORE

  4. 7. In vivo imaging of leukocyte-endothelium interactions in septic lung injury

    Author : Jonas Roller; Kirurgi; []
    Keywords : Sepsis; Acute lung injury; Leukocyte recruitment; Intravital fluorescence microscopy;

    Abstract : Excessive accumulation of leukocytes in the lung represents a key feature in the development of an acute lung injury (ALI). Numerous studies demonstrated that leukocyte rolling is a compulsory precondition for the firm adhesion in organs. However, it seems that the recruitment process of leukocytes in the lung is more complex. READ MORE

  5. 8. Calcium Responses in the Renal Afferent Arteriole to Angiotensin II and Norepinephrine Stimulation

    Author : Mark Kornfeld; Klinisk neurofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; norepinephrine; angiotensin II; smooth muscle cells; afferent arteriole; calcium; Kidney; renal hemodynamics; Physiology; Fysiologi;

    Abstract : Studies were performed to investigate the influence of the vasoconstrictors angiotensin II (AII) and norepinephrine (NE) on calcium metabolism in smooth muscle cells of afferent arterioles. Fura-2 and image analysis techniques were used to evaluate calcium responses in the proximal and distal parts of afferent arterioles with attached glomeruli. READ MORE

  6. 9. Vulvar vestibulitis syndrome : pathophysiology of the vestibular mucosa

    Author : Nina Bohm-Starke; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Vulvar vestibulitis syndrome; immunohistochemistry; QST; COX 2; NOS; laser Doppler perfusion imaging; intraepithelial nerve fibres; pain thresholds; sensory stimulation.;

    Abstract : Objective: The main purpose of the study was to survey possible pathophysiological changes of the vestibular mucosa in women with vulvar vestibulitis syndrome with regard to the clinical findings of superficial dyspareunia and mucosal erythema. Methods: Biopsies analysed with immunohistochemistry were used to study the morphology, distribution and neuropeptide content of the peripheral nerves, and the microvascularisation of the vestibular mucosa.

  7. 10. Influence of Islet-derived Factors in Islet Microcirculation and Endocrine Function

    Author : Carl Johan Drott; Per-Ola Carlsson; Leif Jansson; Albert Salehi; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes mellitus; pancreas; blood flow; islet vascularity; islet-derived; TSP-1; ghrelin; CART; irisin; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Diabetes mellitus is a disorder with complex pathology and is frequently associated with vascular complications. In the islet micro milieu locally generated factors may affect both the physiology and the morphology of the tissue. READ MORE
