1. 1. Calcium Homeostasis After Thyroid Surgery

   Författare :Pia Lindblom; Lund Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PTH-peripheral effects; hPTH- 1-34 infusion; EDTA infusion; Set-point; Vitamin D3; PTH; Calcium; Thyroid surgery; Postoperative hypocalcemia; Bone density.; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Reduced thyroid hormones;

   Sammanfattning : Calcium homeostasis after thyroid surgery was studied during the immediate postoperative period and after one year. One day after hemithyroidectomy ionised calcium decreased whereas basal PTH did not change. EDTA stimulated maximal and total PTH secretion and set-point decreased on postoperative day 1 and normalised on day 7. LÄS MER

3. 2. 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. 3. Calcium channel activity and force regulation in smooth muscle: Effects of polyamines and growth stimulation

   Författare :Maria Gomez; Kardiovaskulär forskning - immunitet och ateroskleros; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; verapamil; tissue culture; portal vein; patch-clamp; calcium; spermidine; spermine; polyamines; excitation-contraction; smooth muscle; calcium channel; ionomycin.; Physiology; Fysiologi;

   Sammanfattning : The initial signal for contraction in smooth muscle is an increase in [Ca2+]i. Ca2+ ions can either enter the cytosol from the extracellular medium or be released from intracellular stores. Voltage-operated Ca2+ channels (VOC) play a dominant role in the activation of smooth muscle contraction. LÄS MER

5. 4. 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

7. 5. Submicron Calcium Phosphate Spheres for Biomedical Applications : Synthesis and Use

   Författare :Tao Qin; Håkan Engqvist; Fredrik Nikolajeff; Jie Huang; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium phosphate; spheres; dentinal hypersensitivity; drug release; tooth bleaching;

   Sammanfattning : Calcium phosphate spheres as biomaterials have been attracting attention in recent years. Calcium phosphate occurs naturally in bone, and a hollow structure could be advantageous for drug loading and release. LÄS MER
