1. 41. Studies of lipolysis and neuroendocrine rhythms in cluster headache

   Författare :Eva Laudon Meyer; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cluster headache; autonomic nervous system; hypothalamus; lipolysis; microdialysis;

   Sammanfattning : Cluster headache (CH) is characterised by excruciating, unilateral headache attacks, which in the episodic form appear in clusters for weeks or even months. The headache attacks are often accompanied by ipsilateral, cranial autonomic symptoms supporting a local peripheral sympathetic deficit and a parasympathetic discharge. LÄS MER

3. 42. Consequences of Arterial Switch Operation in Children Born with Transposition of the Great Arteries

   Författare :Cecilia Falkenberg; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transpositon of the great arteries; arterial switch operation; autonomous nerves system; norepinephrine; heart rate variability; cardiopulmonary bypass; piglets;

   Sammanfattning : Abstract Background: The introduction of the arterial switch operation (ASO) made it the procedure of choice for surgical correction of transposition of the great arteries. A majority of the sympathetic nerves innervate the heart alongside the great vessels; these are therefore likely to be damaged during the surgical procedure; imposing new challenges and questions that need to be addressed.

4. 43. Defense-related inhibition of sympathetic nerve activity: Insights from neuroimaging and monozygotic twins on related cortical processes and clinical potential

   Författare :John Jonsson Eskelin; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microneurography; MEG; EEG; MRI; blood pressure; defence reaction; cortical autonomic network;

   Sammanfattning : This thesis investigates a physiological phenomenon observed in the peripheral sympathetic nervous system in response to various stressors and tries to bring it closer to clinical research. Sudden surprising stimulation can evoke a transient inhibition of sympathetic nerve activity to blood vessels in the human body which is also predictive of the blood pressure response. LÄS MER

5. 44. Mind and body exercises : associations with mental health, antidepressant medication, autonomic functioning and inflammatory biomarkers

   Författare :Lina Rådmark; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Stress, depression and stress-related mental ill-health are common in societies all over the world, and people tend to use both conventional care within the health care system and complementary treatment methods to handle the related symptoms. Still, there is sparse information on whether, how and when to combine these different treatment modalities, in spite of their relatively widespread use. LÄS MER

7. 45. Expression and regulation of neuronal messenger molecules : focus on the NO-cGMP pathway and galanin in autonomic and sensory neurons

   Författare :Kristina Holmberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :adrenal gland; autonomic ganglia; cGMP; dorsal root ganglion; galanin; immunohistochemistry; in situ hybridization; nerve growth factor; neuropeptides; nitric oxide synthase; sodium nitroprusside; transgenic mice;

   Sammanfattning : The autonomic nervous system consists of the sympathetic, parasympathetic and enteric divisions. The sympathetic pre- and paravertebral neurons are in principle of noradrenergic phenotype. However, originally pharmacological experiments indicated that sympathetic fibers projecting to the sweat glands are cholinergic. LÄS MER
