  1. 1. The laryngeal mucosa and the superior laryngeal nerve of the rat : an immunohistochemical and electron microscopic study

    Författare :Siw Domeij; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superior laryngeal nerve; paraganglia; substance P; calcitonin gene-related peptide; neuropeptide Y; vasoactive intestinal polypeptide; enkephalin; mast cells; electron microscopy; immunohistochemistry;

    Sammanfattning : Neuropeptides are present in nerve fibers of the upper and lower airways. Local release of these substances may be of importance for the pathophysiology of airway disorders and may play a role in responses to different stimuli. However, little is known about the distribution of neuropeptides in the larynx. LÄS MER

  3. 2. Characterization of the perturbed differentiation in neuroblastoma, aided by the analysis of normal sympathetic nervous system development

    Författare :Carolina Gestblom; Lund Wallenberg Neurocentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; development; TrkA; apoptosis; proliferation; sympathetic nervous system; neuronal; paraganglia; neuroblastoma; chromaffin; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Neuroblastoma is a pediatric tumor derived from cells in the sympathetic nervous system. In an attempt to explain the heterogeneous clinical behavior of neuroblastoma tumors, neuroblastomas have been characterized with regard to their degree of sympathetic differentiation. LÄS MER

  4. 3. Developmental and stress induced changes in peptide and catecholamine content of the paraaortic paraganglia

    Författare :Lars-Magnus Wikström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :paraganglia; adrenal gland; enkephalin; galanin; NPY; catecholamines; development; asphyxia; hypoglycemia; reserpine;

    Sammanfattning : The paraaortic body (PAB) is the largest extra-adrenal paraganglion and during the perinatal period it contains a substantial amount of catecholamines (CAs). The PAB also contain peptides, whose function in the PAB is not clear. LÄS MER

  5. 4. Tumors of the adrenal glands : genetic and diagnostic aspects

    Författare :Fredrika Svahn; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Adrenal tumors have varying clinical presentation, malignancy rates and patient morbidity. Adrenal cortical carcinomas (ACCs) are malignant tumors originating from the adrenal cortex. LÄS MER

  7. 5. Genetic and molecular background of pheochromocytoma and paraganglioma

    Författare :Adam Stenman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pheochromocytomas (PCC) and abdominal paragangliomas (PGL), collectively denoted PPGL, are neuroendocrine tumors (NET) with a highly diverse genetic and molecular etiology, arisen in the adrenal medulla and abdominal paraganglia respectively. The tumors often cause cardiovascular symptoms due to the high production of catecholamines, and malignancy occurs in 10% of the PCCs and 30% of the PGLs. LÄS MER
