  1. 1. 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

  3. 2. 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.

  5. 4. Intracellular components involved in parathyroid sensing of extracellular calcium

    Författare :Isaac G. Onyango; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Parathyroid hormone; secretion; Src kinase; ERK; PI 3-kinase; PKC; extracellular calcium; parathyroid cell; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : Parathyroid glands are the primary regulator of extracellular calcium ([Ca2+]e). Ca2+ plays a key role in many fundamental biological processes and is also an essential structural component of the skeleton. The parathyroid chief cells detect small changes in [Ca2+]e and respond by altering the secretion of parathyroid hormone (PTH). LÄS MER

  7. 5. New Insights in Genetic and Epigenetic Mechanisms Involved in Parathyroid Tumorigenesis

    Författare :Lee Starker; Peyman Björklund; Barbra Miller; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parathyroid; yumorigenesis; mutation; exome sequencing;

    Sammanfattning : Primary hyperparathyroidism (pHPT) is a pathology associated with one or multiple hyperfunctioning parathyroid glands.  The disease prevalence occurs in roughly 1-2% of the population primarily post-menopausal women.  The molecular pathology of the disease is poorly understood.
