11. Calcium and Phospholipases in Orexin Receptor Signaling
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).

12. Calcium Homeostasis in Patients with Graves' Disease
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
13. Metabolic Disturbances in Relation to Serum Calcium and Primary Hyperparathyroidism
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
14. Calcium calmodulin-dependent protein kinase signal transduction in cerebral arteries
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
15. Porous Amorphous Calcium Carbonate and Phosphate : Synthesis and Application
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.
