  1. 1. Preservation of parathyroid function in thyroid and parathyroid surgery

    Författare :Stefan Ander; Göran Åkerström; Linköpings universitet; []
    Nyckelord :Human parathyroid glands; vascular supply; parathyroid preservation; laser Doppler flowmetry; iPTH; autotransplantation; xenotransplantation; a thymic mice; angiogenesis; immunohistochemistry; electron microscopy; ultrastructure; autoradiography; MEDICINE; MEDICIN;

    Sammanfattning : Preservation of normal parathyroid function and calcium homeostasis after operations on the thyroid and parathyroid glands is a difficult assignment in endocrine surgery, and it is crucial to minimise the risks of permanent postoperative hypoparathyroidism. The aim of this thesis was to study the vascular supply of the parathyroid glands and the revascularisation, growth, and function of transplanted parathyroid tissue, in order to add new information about parathyroid preservation.

  3. 2. Neurohormonal Modulators in the Parathyroid Gland. Localization and regulation

    Författare :Lena Luts; Malmö Patologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Receptor; In situ hybridization; Immunocytochemistry; Nitric Oxide Synthase; Endothelin; Neuropeptides; Chromogranin; Parathyroid adenoma; Parathyroid gland; Parathyroid hormone; mRNA; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : The occurrence and distribution of neurohormonal peptides, neuroendocrine markers and receptors in parathyroid nerve fibers and endocrine cells are described, using immunocytochemistry, in situ hybridization, image analysis and reverse transcriptase polymerase chain reaction. Immunocytochemical studies revealed that parathyroid glands of chicken, rat, guinea-pig, cat, dog and sheep contained adrenergic-, cholinergic-, and peptide-containing nerve fibers. LÄS MER

  4. 3. Growth of parathyroid glands : genetic and functional aspects

    Författare :Stiina Välimäki; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Parathyroid; primary hyperparathyroidism; secondary hyperparathyroidism; parathyroid carcinoma; chromosome 1; HDAC1; HRPT2; CASR; CAS; VDR; PTH; loss of heterozygosity; tumor suppressor gene; patch clamp; membrane potential; K channels;

    Sammanfattning : Ca2+ is an essential ion with a variety of important functions in the body and it is crucial that the Ca2+ levels are precisely regulated. One of the hormones regulating these processes is parathyroid hormone (PTH) secreted from the parathyroid glands. LÄS MER

  5. 4. Wnt/β-Catenin Signalling in Parathyroid Tumours

    Författare :Peyman Björklund; Gunnar Westin; Göran Åkerström; Tommy Andersson; Uppsala universitet; []
    Nyckelord :Surgery; Hyperparathyroidism; β-catenin; Mutation; Human parathyroid cell line; LRP5; Alternative splicing; Kirurgi;

    Sammanfattning : Primary hyperparathyroidism (pHPT) due to parathyroid tumours with hypersecretion of parathyroid hormone and hypercalcaemia is a common disease with incompletely understood etiology affecting more than 1 % of the population, primarily postmenopausal women. In secondary hyperparathyroidism (sHPT), parathyroid tumours develop in response to calcium and vitamin D deficiency generally in patients with uraemia. LÄS MER

  7. 5. Retinoids and vitamin D in skin and parathyroid glands

    Författare :Liu Wei; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; all-trans retinoic acid 9-cis retinoic acid vitamin A. vitamin D. CRBP. CRABP. RAR. RXR. parathyroid hormone. calcium receptor; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Vitamin D3 (VitD3) and retinoids are important factors involved in differentiation and proliferation in many cell systems. Their effects in skin, where retinoids and vitamin D are known to be crucially involved in keratinocyte differentiation and function,, and in the parathyroid, the overall regulatory organ in calcium homeostasis were studied.
