1. 1. Incidentally discovered adrenal tumours, adrenal metastases and pheochromocytomas - Clinical and epidemiological aspects

   Författare :Andreas Muth; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Incidental Findings; Adrenal incidentaloma; Adrenal Gland Neoplasms; Adrenalectomy; Follow-Up Studies; Quality of Life; Pheochromocytoma epidemiology; Pheochromocytoma genetics; Paraganglioma epidemiology; Paraganglioma genetics;

   Sammanfattning : With increasing use of high resolution radiological imaging incidentally discovered adrenal tumours (adrenal incidentalomas, AI) have become a common clinical problem. The aim of work-up and follow-up of patients with AI is to detect malignant (primary or metastatic) and/or hormone-producing tumours. LÄS MER

3. 2. Inflammation-Induced Gene Expression in Brain and Adrenal Gland

   Författare :Linda Engström; Anders Blomqvist; Tomas Hökfelt; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inflammation; brain; adrenal gland; stress; lipopolysaccharide; interleukin-1; Neurobiology; Neurobiologi;

   Sammanfattning : The autonomic nervous system serves to maintain a constant inner environment, a process termed homeostasis. Thus, in response to the homeostatic challenge posed by infectious agents, the autonomic nervous system answers to signals from the immune system and elicits adaptive physiological and behavioral reactions.

4. 3. Endothelin-1-immunoreactive protein and neuroendocrine differentiation and nerve supply in human non-neoplastic and neoplastic adrenal cortex : Immunohistochemical, ultrastructural, and biochemical findings

   Författare :Qing Li; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; adrenal cortex; human; endothelin-related protein; innervation; neuroendocrinedifferentiation; immunohistochemistry; electron microscopy; biochemistry; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

   Sammanfattning : The occurrence and distribution of endothelin (ET)-1-immunoreactive (ir) protein, neuro-endocrine markers and neurohormonal peptides in endocrine cells and nerves in human non-neoplastic and neoplastic adrenal cortex are described.ET-1-ir cell groups were regularly seen in human adrenal cortex, mainly in zona fasciculata, but not in the medulla.

5. 4. On the actions of neurotrophic factors on the chromaffin cells of the adrenal medulla

   Författare :Petter Förander; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Neural crest; chromaffin cells; neurotrophic factors; NGF; NT-3; NT4; CNTF; GDNF; TGFß; FGF2; glucocorticoids; Intra oculartransplantation ; primary cultures; neurite outgrowth;

   Sammanfattning : Chromaffin cells producing adrenaline or noradrenaline are the predominant cell type in the adrenal medulla, but ganglion cells and Schwann cells are also present. All cells of the adrenal medulla are derived from the neural crest, which is a transient neuroectoderm-derived embryonic structure. LÄS MER

7. 5. Hypoxia and auto resuscitation in the neonatal rodent with special reference to the sympatho-adrenal system

   Författare :Shi-Zeng Yuan; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :adrenal medulla; apnea; asphyxia; autoresuscitation; catecholamines; SIDS;

   Sammanfattning : Preterm infants exhibit irregular breathing with frequent episodes of apnea, which may be associated with cyanosis and bradycardia. Perinatal asphyxia causes a considerable amount of morbidity and mortality that occurs during early life. Studies of mechanisms responsible for perinatal asphyxia are therefore very important. LÄS MER
