  1. 16. Atrial Fibrillation after Coronary Artery Bypass Surgery : A Study of Causes and Risk Factors

    Författare :Lena Jidéus; Dan Lindblom; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Atrial fibrillation; catecholamines; coronary artery bypass surgery; heart rate variability; neuropeptides; premature atrial contraction; thoracic epidural anaesthesia; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

    Sammanfattning : The aim was to study pathophysiological mechanisms and risk factors for developing atrial fibrillation (AF) after coronary artery bypass grafting (CABG), and the effect of thoracic epidural anaesthesia (TEA).The study comprised 141 patients undergoing CABG, including 45 patients randomised for TEA intra- and postoperatively.

  3. 17. Pituitary adenylate cyclase activating polypeptide : Expression and neurotrophic activity in the rat brain

    Författare :Ylva Skoglösa; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; in situ hybridisation; rat; TBI; BDNF; NGF; GDNF; PACAP; PRI; TUNEL; apoptosis; CNS; PNS; neuropeptides; neurotrophic factors; reactive oxygen species; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : Neurotrophic factors play an important role in regulating naturally occurring cell death during neurogenesis. In addition to classical neurotrophic factors, some neurotransmitters and neuropeptides have been shown to exhibit neurotrophic activities. LÄS MER

  4. 18. Preproenkephalin Gene and mRNA : Studies of Structure, Function, Cocaine Responses in an Animal Model, and Genetic Association with Human Opiate Addiction

    Författare :Karl Steven LaForge; Fred Nyberg; Peter S. Eriksson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological research on drug dependence; Neuropeptides; Endogenous opioid system; Drug addiction; Heroin; Cocaine; Gene expression; Genetic association; Biologisk beroendeforskning; Biological research on drug dependence; Biologisk beroendeforskning;

    Sammanfattning : The endogenous opioid enkephalin neuropeptides are mediators of pain perception and have been implicated in human addictions. The preproenkephalin gene and its mRNA have also provided many examples of tissue- and species-specific variations in mRNA structure produced through a variety of transcriptional and post-transcriptional mechanisms.

  5. 19. The Enteric Nervous System, Plasticity and Survival

    Författare :Katarina Sandgren; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; Nitric oxide synthase; Neuropeptides; Neuronal survival; Lethal spotted mice; Interstitial cells of Cajal; Hirschsprung s disease; Cell cultures; Enteric nervous system; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : The thesis deals with plasticity in terms of neurotransmitter expression and survival of neurons in the adult enteric nervous system (ENS). Several motility disorders have been suggested to originate in developmental defects, neurodegeneration, or insufficient innervation by the ENS. LÄS MER

  7. 20. Gut peptides in gastrointestinal motility and mucosal permeability

    Författare :Md. Abdul Halim; Webb Dominic-Luc; Per M Hellström; Lars Fändriks; Uppsala universitet; []
    Nyckelord :Gut regulatory peptides; Neuropeptides; Gastrointestinal mucosal permeability; Gastrointestinal motility; GLP-1; NPS; ROSE-010;

    Sammanfattning : Gut regulatory peptides, such as neuropeptides and incretins, play important roles in hunger, satiety and gastrointestinal motility, and possibly mucosal permeability. Many peptides secreted by myenteric nerves that regulate motor control are also produced in mucosal epithelial cells. LÄS MER
