    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgical stress; Corticosterone; Buprenorphine; Analgesia; Rats.; Försöksdjursvetenskap - Jämförande medicin; Comparative Medicine;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : 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). LÄS MER

  4. 3. Maternal Separation in Rats : An Experimental Model for Long-Term Effects of Early Life Experiences on Neurochemistry, Voluntary Ethanol Intake and Exploration and Risk Assessment Behavior

    Författare :Erika Roman; Ingrid Nylander; J. Dee Higley; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical pharmacology; Handling; Maternal Deprivation; Environment; Opioids; Dopamine; Alcohol; Stress; Concentric Square Field; Open Field; Elevated Plus-maze; Farmaceutisk farmakologi; Pharmaceutical pharmacology; Farmaceutisk farmakologi;

    Sammanfattning : The period of early life is important for the development of individual brain function and behavior. Human studies have shown altered vulnerability to develop psychopathology and/or excessive drug intake, possibly leading to dependence, as a consequence of early life experiences. LÄS MER

    Sammanfattning : Nearly one million new cases of gastric cancer are diagnosed annually throughout the world. Even though the incidence has fallen dramatically in recent decades, this disease is still the second leading cause of cancer death in a global perspective. LÄS MER

  7. 5. Regeneration in the adult brain after focal cerebral ischemia : exploration of neurogenesis and angiogenesis

    Sammanfattning : Background: Ischemic stroke ranks as the third major cause of clinical mortality and the leading cause of handicap in adults. Each year, stroke occurs in about 30,000 Swedes. The severity of an acute ischemic stroke depends mainly on the degree and duration of local cerebral blood flow (lCBF) reduction. LÄS MER
