  2. 1. The Influence of the Adenosine A1-receptor on Tubuloglomerular Feedback and Renin Release

    Author : Russell Brown; A Erik G Persson; Pontus Persson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; adenosine; tubuloglomerular feedback; renin release; blood pressure; micropuncture; Fysiologi; Physiology; Fysiologi;

    Abstract : The kidneys play a vital role in the maintenance of extracellular fluid and electrolyte balance and blood pressure. Adenosine, acting through the adenosine A1-receptor (A1R), and nitric oxide have been implicated in several of the regulatory mechanisms in the kidney. READ MORE

  5. 3. 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

  6. 4. Unraveling the importance of solid and adsorbed phase mercury speciation for methylmercury formation, evasion and bioaccumulation

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mercury; methylmercury; aquatic systems; estuary; Hg; MeHg; bioaccumulation; methylation; demethylation; evasion; sediment; water; terrestrial sources; atmospheric sources; climate change; eutrophication;

    Abstract : Monomethylmercury, MeHg, is formed under anoxic conditions in waters, sediments and soils and then bioaccumulated and biomagnified in aquatic food webs, negatively effecting both human and wildlife health. It is generally accepted that precipitation of mercury, Hg, and adsorption of Hg to e.g. READ MORE

  7. 5. Aspects of Power Allocation in Massive MIMO
