  2. 1. The Role of Dopamine-Metabolising Enzymes in Renal Sodium Handling. An Experimental Study in vivo

    Author : Cecilia Odlind; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; dopamine; kidney; sodium; MAO; COMT; rat; mice; RBF; oxygen; renal; L-dopa; DOPAC; entacapone; phenelzine; dopamine receptors; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : Dopamine (DA) has been shown to act as an intrarenal natriuretic hormone and defects in the renal DA system have been associated with some forms of hypertension. How the DA activity is upregulated durin- increased sodium intake is, however, unknown. READ MORE

  4. 2. Intrarenal oxygen homeostasis in acute and chronic kidney disease

    Author : Oskar Nensén; Fredrik Palm; Börje Haraldsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney; acute kidney injury; oxygen; kidney disease; renal physiology; Fysiologi; Physiology;

    Abstract : Renal hypoxia has been recognized as a common feature of acute and chronic kidney injury arising from varying etiologies. It has also been proposed to provide a driving mechanism for the transition from acute to chronic kidney disease (CKD). READ MORE

  5. 3. 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

  6. 4. Assessment of microvascular function by use of transdermal iontophoresis : methodological aspects

    Author : Erik Droog Tesselaar; Folke Sjöberg; Angela Shore; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Iontophoresis; Microcirculation; Laser-Doppler; Acetylcholine; Sodium nitroprusside; Pharmacodynamics; Pharmacokinetics skin; Physiology and pharmacology; Fysiologi och farmakologi;

    Abstract : Assessment of the microcirculation is of major importance in understanding the physiology of the vasculature and in assessing te vascular effects of pathological conditions such as diabetes, hypertension and sepsis. Transdermal iontophoresis can be used to non‐invasively introduce vasoactive drugs into the skin. READ MORE

  7. 5. Transport of sodium and protons in the human placenta. Mechanisms in normal pregnancy and alterations in intrauterine growth restriction

    Author : Martin Johansson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; placenta; Na K ATPase; Na H exchanger; H K ATPase; intrauterine growth restriction; BeWo cells; epithelial transport;

    Abstract : The syncytiotrophoblast cell of the human placenta represents the interface between maternal and fetal blood supplies. This polarized epithelium consists of a maternal facing microvillous membrane (MVM) opposing a fetal facing basal membrane (BM). This unique syncytial cell is responsible for transfer of all nutrients to the developing fetus. READ MORE
