  1. 1. The role of catecholamines in regulation of renal tubular sodium transport

    Författare :Ulla Holtbäck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :sodium balance; Na ; H -antiporter; Na ; K -ATPase; renal proximaltubules; hormonal regulation.;

    Sammanfattning : Renal sodium metabolism, a major determinant of arterial blood pressure, is regulated with remarkable precision by a variety of endocrine, autocrine and neuronal factors. All these factors are known to regulate sodium metabolism by affecting the rate of renal tubular sodium reabsorption. LÄS MER

    Sammanfattning : Modern chemical technology is an efficient tool for solving problems, particularly within the complex environment of the pulp and paper industry, and the combination of experimental studies, mill data and mass balance calculations are of fundamental importance to the development of the industry. In this study various examples are presented, whereby chemical technology is of fundamental importance. LÄS MER

  4. 3. Poly(Ethylene Oxide) Based Bottle-Brush Polymers and their Interaction with the Anionic Surfactant Sodium Dodecyl Sulphate : Solution and Interfacial Properties

    Författare :Joseph Iruthayaraj; Per M. Claesson; Regine v. Klitzing; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEO brush polymers; brush polymers; PEO; poly ethylene oxide ; polymer-surfactant; sodium dodecyl sulphate SDS ; Ellipsomtery; PEO-SDS interactions; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : The aim of this thesis work is to study the physico-chemical properties of poly(ethylene oxide), PEO, based brush polymers both in solution and at solid/aqueous interfaces. The importance of studying the surface properties of brush polymers can be related to a broad spectrum of interfacial-related applications such as colloidal stability, lubrication, detergency, protein repellency to name a few.

  5. 4. Hormones and fluid balance during pregnancy, labor and post partum

    Författare :Anitha Risberg; Mats Sjöquist; Kerstin Olsson; Sven Lyrenäs; Karolina Kublickiene; Uppsala universitet; []
    Nyckelord :cortisol; estradiol; glucose; labour; osmolality; oxytocin; parturition; pregnancy; pregnancy-induced hypertension; progesterone; vasopressin; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : The aim of this thesis was to determine any association between plasma oxytocin and vasopressin concentrations and renal water and sodium excretion during normal pregnancy. In addition to investigate changes in concentrations of estradiol, progesterone, oxytocin, cortisol, and glucose in the blood before and in the nearest hours after delivery and if treatment with oxytocin affected these concentrations and the fluid balance during the different stages of labour.

  7. 5. Film Formation from Dispersions - Preparation and Mechanisms

    Författare :Stefan Erkselius; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; Polymer technology; decomposition; sodium persulfate; hyrdoxyethyl cellulose; salt; surfactants; drying; stabilization; latex; Film formation; dispersions;

    Sammanfattning : Improved environmental consciousness and harsh legislation concerning volatile organic compounds (VOCs) during the 1980s led to an increase in the development in the field of polymer colloids. Solvent born coatings were replaced by polymer dispersions in aqueous solution, so called latex dispersions. LÄS MER
