  1. 1. Surgical Stress in Rats The Impact of Buprenorphine on Postoperative Recovery

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Renée Sundbom; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgical stress; Corticosterone; Buprenorphine; Analgesia; Rats.; Försöksdjursvetenskap - Jämförande medicin; Comparative Medicine;

    Abstract : During surgery, both anesthesia and tissue damage cause physiological stress responses in the body. The hypothalamic-pituitary-adrenal (HPA) axis is activated with increased levels of glucocorticoids. READ MORE

    Abstract : Background Animal models can be used to mimic human conditions of psychopathology, and also as pre-clinical models to evaluate candidate drugs. With hormonal treatment it is possible to produce behavior in the rat which corresponds to the mental symptoms of pre-menstrual syndrome (PMS), and pre-menstrual dysphoric disorder (PMDD). READ MORE

  3. 3. Neurobiological Consequences of Social Conditions and Alcohol Exposure in Adolescent rats

    University dissertation from Uppsala University

    Author : Linnea Granholm; Uppsala universitet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescence; alcohol; amphetamine; dopamine; dorsal striatum; dynorphin; endogenous opi- oids; enkephalin; high-speed chronoamperometry; housing conditions; rats; nociceptin orphanin FQ; radi- oimmunoassay; self-administration; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : Adolescence represents a time of extensive reorganisation and maturation of brain circuits involved in emotions, motivation and cognition and it is a period particular sensitive for external stimuli. External stimuli can be both socio-environmental factors and exposure to exogenous compounds such as drugs of abuse (e.g. alcohol). READ MORE

  4. 4. Parathyroid hormone for bone repair and implant fixation - Experiment in rats

    University dissertation from Department of Orthopaedics, Lund University

    Abstract : Intermittently administered PTH is known to increase bone mass in osteoporosis models. We studied its effects in bone repair and implant fixation, using histological and mechanical techniques in rats. READ MORE

  5. 5. Post-Ischemic Housing Conditions Influence On Gene Transcription And Translation After Permanent Focal Brain Ischemia In Rats

    University dissertation from Department of Clinical Neuroscience, Lund University

    Author : Li-Ru Zhao; Lunds universitet.; Lund University.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; brain-derived neurotrophic factor; mRNA; nerve growth factor-induced gene A; corticosteroid receptors; in situ hybridization; Neurologi; neurophysiology; Neurology; neuropsychology; brain ischemia; enriched environment; neuropsykologi; neurofysiologi;

    Abstract : Enriched environment (EE) housing significantly ameliorates neurological deficits induced by cortical brain ischemia without changing infarction size, suggesting that EE-related functional benefits are associated with neuronal plasticity events in the remaining tissue. Brain-derived neurotrophic factor (BDNF), nerve growth factor-induced gene A (NGFI-A) and corticosteroid receptors (mineralocorticoid receptor, MR; glucocorticoid receptor, GR) have been demonstrated to be involved in brain plasticity.
