  1. 11. Calcium and Phospholipases in Orexin Receptor Signaling

    Författare :Lisa Johansson; Jyrki Kukkonen; Karl Åkerman; Christopher S. Leonard; Uppsala universitet; []
    Nyckelord :Physiology; orexin; receptor; calcium; phospholipase; cell signaling; GPCR; Fysiologi;

    Sammanfattning : The neuropeptides orexin-A and -B act as endogenous ligands for G-protein-coupled receptors (GPCRs) called OX1 and OX2 receptors. Previous observations have established that orexin receptors have an ability to couple to different G-proteins and signaling pathways and induce Ca2+ elevations via both receptor-operated Ca2+ channels (ROCs) and store-operated Ca2+ channels (SOCs).

  2. 12. Calcium Homeostasis in Patients with Graves' Disease

    Författare :Maria Annerbo; Per Hellman; Peter Stålberg; Peyman Björklund; Filipsson Nyström Helena; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Graves Disease; Calcium homeostasis; Total thyroidectomy; Bone metabolism; Calcium sensing receptor; Surgery; Kirurgi;

    Sammanfattning : Patients with Graves´ Disease (GD) have a higher risk of developing more severe and prolonged hypocalcaemia after total thyroidectomy (TT) than patients who undergo surgery for benign atoxic goitre. Since TT is the most effective treatment for GD, it is crucial to identify mechanisms for postoperative hypocalcaemia. LÄS MER

  3. 13. Metabolic Disturbances in Relation to Serum Calcium and Primary Hyperparathyroidism

    Författare :Emil Hagström; Per Hellman; Ewa Lundgren; Jonas Rastad; Svante Jansson; Uppsala universitet; []
    Nyckelord :Surgery; Primary hyperparathyroidism; Parathyroidectomy; Insulin sensitivity; Lipoproteins; Glucose metabolism disorders; Bone density; Calcium; Kirurgi;

    Sammanfattning : Primary hyperparathyroidism (pHPT), characterized by elevated serum levels of calcium and parathyroid hormone (PTH), is associated with a number of metabolic derangements causing secondary manifestations. These include osteoporosis and increased risk of fractures, but also risk factors for cardiovascular morbidity and mortality. LÄS MER

  4. 14. Calcium calmodulin-dependent protein kinase signal transduction in cerebral arteries

    Författare :Roya Waldsee; Lund Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CAMK; Ednothelin receptors; Calcium; gene regulation;

    Sammanfattning : Cerebral arteries participate actively in the response that follows an episode of cerebral ischemia in man and rat. It has been shown that the vascular endothelin receptor expression is increased in stroke and organ culture. LÄS MER

  5. 15. Porous Amorphous Calcium Carbonate and Phosphate : Synthesis and Application

    Författare :Rui Sun; Ocean Cheung; Maria Strømme; Ken Welch; Denis Gebauer; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amorphous calcium carbonate; amorphous calcium phosphate; stabilization; crystallization; porous material; drug delivery; gas adsorption; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : The synthesis of porous amorphous calcium carbonate (ACC) and porous amorphous calcium phosphate (ACP) was developed in this thesis. Porous ACC with specific Brunauer–Emmett–Teller (BET) surface area of >350 m2/g was synthesized using a surfactant free approach. The high surface area of porous ACC was related to its nanostructure. LÄS MER
