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

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

   Abstract : 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. READ MORE

4. 2. Pathophysiology of blood-brain barrier, brain edema and cell injury following hyperthermia : New role of heat shock protein, nitric oxide and carbon monoxide : an experimental study in rat using light and electron microscopy

   Author : Hari Shanker Sharma; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; blood-brain barrier; heat stress; hyperthermia; brain edema; serotonin; nitric oxide; carbon monoxide; heat shock protein; glial fibrillary acidic protein; myelin basic protein; opioids; histamine; catecholamines; naloxone; indomethacin; p-CPA; electron microscopy; immunocytochemistry; Cellbiologi; Cell biology; Cellbiologi; Human Anatomy; anatomi;

   Abstract : This thesis deals with the molecular mechanisms of hyperthermia induced brain damage in rats. The results clearly establish that hyperthermia caused by 4 h heat stress at 38° C is associated with a breakdown of the blood-brain barrier (BBB) permeability which seems to be instrumental in causing brain edema and cell injury.

5. 3. Satellite cells in human skeletal muscle : molecular identification quantification and function

   Author : Mona Lindström; Lars-Eric Thornell; Hannu Kalimo; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; satellite cell markers; NCAM; Pax7; MyoD; myogenin; DLK1 FA1; c-Met; human skeletal muscle; immunohistochemistry; muscle growth; muscle hypertrophy; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi; anatomi; Human Anatomy;

   Abstract : Skeletal muscle satellite cells located between the plasma membrane and the basal lamina of muscle fibres, could for many years, only be studied in situ by electron microscopy. The introduction of immunohistochemistry and the discovery of molecular markers of satellite cells then made them accessible for light microscopic studies and a wealth of information is today available.

6. 4. Neuro-immune regulation of macromolecular permeability in the normal human colon and in ulcerative colitis

   Author : Conny Wallon; Johan Dabrosin Söderholm; Peter Naredi; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colitis; ulcerative; colon; sigmoid; cytology; immunohistochemistry; Gastroenterology; Gastroenterologi;

   Abstract : Background and aim: Persistent stress and life events affect the course of ulcerative colitis (UC) by largely unknown mechanisms. Regulation of epithelial permeability to antigens is crucial for the balance between inflammation and immuno-surveillance, and increased intestinal permeability has been shown in patients with ulcerative colitis.

7. 5. Preservation of parathyroid function in thyroid and parathyroid surgery

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

   Abstract : 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.
