  1. 16. Cardiovascular disease and adrenergic dysfunction in mild primary hyperparathyroidism

    Författare :Mats Birgander; Internmedicin - epidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Primary Hyperparathyroidism; parathyroidectomy; parathyroid hormone; cardiovascular disease; mortality.;

    Sammanfattning : Primary hyperparathyroidism (PHPT) is associated with cardiovascular morbidity and premature death, but the underlying mechanisms are incompletely understood. The aim of this thesis was to investigate cardiovascular parameters and adrenergic function in mild PHPT compared to healthy controls subjects before and after curative parathyroidectomy (PTX).

  3. 17. Plant Calreticulins - isoforms, localization and function

    Författare :Karin Svensson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; arabidopsis thaliana; calcium; isoform; endoplasmic reticulum; chaperone; tunicamycin;

    Sammanfattning : Calreticulin (CRT) is an endoplasmic reticulum (ER)-located protein involved in quality control of newly synthesized proteins as well as in calcium homeostasis of the cell. Most of what is known about CRT arises from studies of mammalian systems. LÄS MER

  4. 18. Phenotypic modulation of vascular smooth muscle in organ culture

    Författare :Anders Lindqvist; Islet cell physiology; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smooth muscle; proliferation; PDGF; Physiology; energy metabolism; calcium; Fysiologi;

    Sammanfattning : Contraction of blood vessels for the regulation of blood flow and pressure is dependent on vascular smooth muscle cells (VSMC) located in the medial layer of the vascular wall. Adult, differentiated VSMC have a well developed contractile system and a low rate of proliferation. LÄS MER

  5. 19. Dynamics of Ca2 handling in vascular smooth muscle

    Författare :Karl Dreja; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smooth muscle; phenotypic modulation; caveolae; Physiology; confocal microscopy; calcium; Fysiologi;

    Sammanfattning : Intracellular Ca2+ is a key regulator of vascular contractility, and thereby of blood perfusion and pressure. Ca2+ signals are essential also for cell migration, proliferation and regulation of numerous enzymes. LÄS MER

  7. 20. Interfacial properties of calcium montmorillonite in aqueous solutions : Density functional theory and classical molecular dynamics studies on the electric double layer

    Författare :Guomin Yang; Göran Lindbergh; Ivars Neretnieks; Michael Holmboe; Jan Forsman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clay minerals; Bentonite; density functional theory; molecular dynamics; GROMACS; electric double layer; electrolytes; ionic liquids; primitive model; CLAYFF forcefield.; Chemical Engineering; Kemiteknik;

    Sammanfattning : The swelling properties of Bentonite are highly affected by clay content and the clay-water interactions that arise from the ion distribution in the diffuse double layer formed near the charged montmorillonite (or smectite) surfaces. Existing continuum models describing the electric double layers, such as classical Poisson-Boltzmann and DLVO theory, ignore the ion-ion correlations, which are especially important for multivalent ions at high surface charge and ionic strength.
