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

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

    Sammanfattning : 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. LÄS MER

  2. 2. Dysfunction in the nigrostriatal system : effects of L-DOPA and GDNF

    Författare :Nina Nevalainen; Ingrid Strömberg; Nancy Zahniser; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson’s disease; L-DOPA; dyskinesia; GDNF; dopamine; glutamate; serotonin; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences;

    Sammanfattning : Parkinson’s disease is a common neurodegenerative disorder caused by nigrostriatal dopamine loss, with motor deficiencies as the primary outcome. To increase the striatal dopamine content, patients are treated with 3,4-dihydroxyphenyl-l-alanine (l-DOPA). LÄS MER

  3. 3. Early Life History of the cold-water coral Lophelia pertusa - with implications for dispersal

    Författare :Susanna Strömberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :larval development; life history traits; dispersal potential; morphology;

    Sammanfattning : For sessile marine invertebrates the pelagic larval stage is the only means for dispersal, and thus govern population connectivity and maintenance of genetic diversity. It is also a kind of life insurance, i.e. it reduces the risk of extinctions. LÄS MER

  4. 4. Developments in Feedstock Analysis and Process Control for Biogas Production

    Författare :Sten Strömberg; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Process control; Biochemical Methane Potential; Process analysis; Feedstock; Biogas;

    Sammanfattning : A sustainable treatment of organic wastes, generation of renewable energy, reduction of green house gas emissions, limiting the eutrophication and closing the nutrient cycles are several environmental challenges for which anaerobic digestion may be a suitable solution. There is today a large amount of available organic waste materials that could serve as potential feedstock for biogas production. LÄS MER

  5. 5. A Standard Mobile Phone as a Chemical Sensor

    Författare :Zafar Iqbal; Mats Eriksson; Stefan Klintström; Tomas Strömberg; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis describes work to investigate the potential of using an ordinary mobile phone to perform chemical sensing by colorimetric analysis of reflected light. The wide availability and familiarity of mobile phones make them excellent devices for aiding consumers in making on site tests in their everyday lives. LÄS MER
