  1. 21. Developmental and stress induced changes in peptide and catecholamine content of the paraaortic paraganglia

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Lars-Magnus Wikström; Karolinska Institutet.; Karolinska Institutet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; paraganglia; adrenal gland; enkephalin; galanin; NPY; catecholamines; development; asphyxia; hypoglycemia; reserpine;

    Abstract : 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. READ MORE

  2. 22. On antidepressant effects of running and SSRI : Focus on hippocampus and striatal dopamine pathways

    University dissertation from Stockholm : Karolinska Institutet, Department of Neuroscience

    Author : Astrid Bjørnebekk; Karolinska Institutet.; Karolinska Institutet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Depression; exercise; neuropeptides; cell proliferation; neurogenesis; NPY; BDNF; Flinders Sensitive Line;

    Abstract : Considering the heterogeneous character of depression, it seems likely that many brain regions are involved mediating the diverse symptoms of depression. For example, the mesolimbic DA system has a central function for motivational behaviors and pleasure seeking, and it is possible that malfunctioning of brain reward systems could be an underlying mechanism of the anhedonia experienced in depressive illness.

  3. 23. The role of neuropeptides in spinal nociceptive mechanisms with special emphasis on galanin, neuropeptide Y and orphanin FQ/nociceptin

    University dissertation from Stockholm : Karolinska Institutet, Department of Laboratory Sciences and Technology

    Author : Isabella Shi Xu; Karolinska Institutet.; Karolinska Institutet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; analgesia; antinociception; flexor reflex; galanin; galanin message-associated peptide GMAP ; neuropeptide Y NPY ; nociceptin; nociception; nocistatin; orphanin FQ; pain;

    Abstract : Several peptides present in sensory neurons and in the spinal cord have been recognized to have inhibitory action in nociception. In this thesis, we have used the flexor reflex preparation in rats to study the role of several proposed inhibitory neuropeptides, galanin, galanin message-associated peptide (GMAP), neuropeptide Y (NPY), orphanin FQ and nocistatin in spinal nociceptive processing under normal conditions, after inflammation or peripheral nerve injury.

  4. 24. Alcohol and the effect on some appetite-regulating hormones in man

    University dissertation from Stockholm : Karolinska Institutet, Department of Molecular Medicine and Surgery

    Author : Jan Calissendorff; Karolinska Institutet.; Karolinska Institutet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Leptin; ghrelin; octanoylated; PYY3-36; GLP-1; obestatin; alcohol; NPY; IGF-1; IGFBP-1; insulin; glucose; testosterone; cortisol; catecholamines;

    Abstract : Beverage containing alcohol has been used for centuries to stimulate appetite. Ingestion of a moderate amount of alcohol increase energy intake. Regulation of food intake is complex. Several factors cooperate such as neural impulses from sensory organs; sight, smell, gut distension, social setting, memory, current energy status and hormones. READ MORE

  5. 25. Neuropeptide expression in mouse disease models

    University dissertation from Stockholm : Karolinska Institutet, Department of Neuroscience

    Author : Margarita Diez; Karolinska Institutet.; Karolinska Institutet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimers disease; autoradiographic ligand binding; CCK; degeneration; dynorphin; enkephalin; galanin; immunohistochemistry; in situ hybridization; lesion; magnetic resonance imaging; megencephaly; NPY; prion infection; substance P.;

    Abstract : The role of neuropeptides and the significance of peptidergic mechanisms in neurodegenerative diseases are still relatively unexplored. In the periphery, nerve injury results in dramatic changes in the expression of neuropeptides (and other molecules). READ MORE
