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

    Author : Linnea Granholm; Ingrid Nylander; Anne-Lie Svensson; Erika Roman; Maria Ellgren; Uppsala universitet; []
    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. 2. Cooling and dopamine

    Author : Roger Roscher; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; electrophysiology; cooling; Hypothermia; swine; lung transplantation; organ preservation; dopamine; circulation; contractility; oxygenation; intensive care; Anestesiologi; intensivvård;

    Abstract : There is little knowledge about the circulatory effects of dopamine in hypothermia. Induced hypothermia has been shown to improve outcome in various settings. Hypothermia is also used for preservation of organs that are harvested for transplantation. READ MORE

  5. 3. On dopamine neurons : nerve fiber outgrowth and L-DOPA effects

    Author : Sara af Bjerkén; Ingrid Strömberg; Kathy Steece-Collier; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dopamine; nerve fiber outgrowth; astrocytes; ventral mesencephalon; GDNF; L-DOPA; L-DOPA induced dyskinesia; Neurobiology; Neurobiologi;

    Abstract : Parkinson’s disease is a disorder mainly characterized by progressive degeneration of dopamine producing neurons in the substantia nigra of the midbrain. The most commonly used treatment strategy is to pharmacologically restore the lost function by the administration of the dopaminergic precursor L-DOPA. READ MORE

  6. 4. Quantitative chemical imaging to study content release from single nanovesicles

    Author : Tho D. K. Nguyen; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Exocytosis; Vesicle; Mass spectrometry imaging; Electron microscopy; Fluorescence microscopy; Electrochemical analysis; NanoSIMS;

    Abstract : Cellular communication is vital for the survival of multicellular organisms. This process often relies on a highly regulated mechanism called exocytosis, which involves the release of chemical signals. During exocytosis, vesicles can fully or partially release their contents.

  7. 5. The biology of cognitive decline and reduced survival in Parkinson disease : prognostic factors in a population-based cohort

    Author : David C Bäckström; Lars Forsgren; Jan Linder; Niklas Lenfeldt; Jan Aasly; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson disease; multiple system atrophy; progressive supranuclear palsy; natural history; cognitive impairment; dementia; predictors of mortality; cerebrospinal fluid biomarkers; prospective; population-based; Neurology; neurologi;

    Abstract : Parkinson disease (PD) is a progressive neurodegenerative disease that affects about 1% of the population over 60 years. The cardinal symptoms are motor disabilities but cognitive decline is also common. About 50% of all persons with PD develop dementia within 10 years after disease onset. READ MORE
