  2. 11. Interaction between Adenosine and Angiotensin II in Renal Afferent Arterioles of Mice

    Author : Enyin Lai; A. Erik G. Persson; Göran Bergström; Uppsala universitet; []
    Keywords : Physiology; adenosine; angiotensin II; afferent arteriole; calcium; nitric oxide; microperfusion; tubuloglomerular feedback; Fysiologi;

    Abstract : Renal arterioles represent the most important effecter site in the control of renal perfusion and filtration. Adenosine (Ado), angiotensin II (Ang II) and nitric oxide (NO) interact in modulating arteriolar tone. The present work investigates the mechanism of this interaction. READ MORE

  4. 12. The Role of Angiotensin II in Experimental Acute Kidney Injury and Cardiorenal Failure

    Author : Sofia Jönsson; Michael Hultström; Helle Prætorius Øhrwald; Uppsala universitet; []
    Keywords : Heart failure; Acute kidney injury; Angiotensin II; Fluid balance; Cardiac function; Renal function;

    Abstract : Blood pressure and fluid regulation are kept constant through the interaction between heart and kidneys. When the systemic blood pressure decreases, the levels of the hormone Angiotensin II increase, leading to vasoconstriction and therefore increased blood pressure. READ MORE

  5. 13. 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. 14. The renin-angiotensin system in renal tubulogenesis. Experimental studies in the rat

    Author : Daina Lasaitiene; Göteborgs universitet; []
    Keywords : angiotensin II; extracellular matrix; inflammation; mitochondrial biogenesis; renal development; renin-angiotensin system; thick ascending limb of Henle; tubulogenesis;

    Abstract : The kidney and the renin-angiotensin system (RAS) are vital regulators of blood pressure and salt-water balance. In order to appropriately regulate circulatory homeostasis, the kidney must undergo normal development, in which the RAS plays a crucial role. READ MORE

  7. 15. Angiotensin-Converting Enzyme : Effects of Smoking and Other Risk Factors for Cardiovascular Diseases

    Author : Liza Ljungberg; Karin Persson; Rolf Andersson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Cardiovascular diseases (CVDs) are the most common cause of death in Western countries. Smoking, hypertension, diabetes mellitus and hypercholesterolemia are considered as major risk factors. However, the underlying mechanisms by which these factors cause CVDs are not entirely clear.
