  4. 3. Microbial communities : descriptors of environmental change in marine ecosystems

    Författare :Li Zhao; Agneta Andersson; Xiao-Ru Wang; Alexander Eiler; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In northern marginal seas, like the northern Baltic Sea, climate change will lead to many alterations, for example increased inflows of nutrients and dissolved organic matter (DOM). Nutrients and DOM are fundamental drivers shaping marine microbial communities, including both bacterial and phytoplankton populations. LÄS MER

  5. 4. Mechanisms of secretagogue action in isolated parietal cells

    Författare :Zhao-Qi Li; Frank Sundler; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The mechanisms of secretagogue action and various intracellular events in isolated pig and rat gastric parietal cells were investigated. The response to gastrin in aminopyrine accumulation, an index of the acid produced and n·apped by the cells, was ilifferent in pig and rat parietal cells. LÄS MER

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

    Författare :Li-Ru Zhao; Sektion IV; []
    Nyckelord :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;

    Sammanfattning : 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.
