  2. 1. Profilin : From the Cell Edge into the Nucleus

    Author : Sara Sadi; Roger Karlsson; Maria Vartiainen; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; profilin; actin; microfilament system; nucleus; SRF; MRTF; MAL; transcription; microtubules; Cell Biology; cellbiologi;

    Abstract : Internal and external signaling dependent changes in cell behavior are directly linked to force-generating remodeling of the actin microfilament system which is juxtaposed to the inside of the plasma membrane. This dynamic filament system is involved in many processes in the cytoplasm and the nucleus of eukaryotic cells. READ MORE

  5. 3. Investigations on Emission Sources in Proton-Nucleus and Nucleus-Nucleus Collisions

    Author : Johan Mårtensson; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; Fysik; Physics; correlation function.; fermion interferometry; t p and d p ratios; target mass dependence; pion angular distribution; pion excitation function; Heavy ion reactions; intermediate energy; cosmic rays; Kosmisk strålning; högenergi;

    Abstract : Emission sources in proton-nucleus and nucleus-nucleus collisions at intermediate energies have been studied. Pion excitation functions from the absolute threshold to 500 MeV have been measured with an ion beam of continuously varying energy with an energy resolution of 1 MeV. READ MORE

  6. 4. Get in tune : chloroplast and nucleus harmony

    Author : Dmitry Kremnev; Åsa Strand; Francis-Andre Wollman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; development; gene expression;

    Abstract : Photosynthetic eukaryots emerged as a result of several billion years of evolution between proeukaryotic cell and ancestral cyanobacteria that formed modern chloroplasts. The symbiotic relationship led to significant rearrangements in the genomes of the plastid and the nucleus: as many as 90 % of all the plastid genes were transferred to the nucleus. READ MORE

  7. 5. The subthalamic nucleus in motor and affective functions : An optogenetic in vivo-investigation

    Author : Adriane Guillaumin; Åsa Wallén-Mackenzie; Konstantinos Meletis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Subthalamic nucleus; optogenetics; basal ganglia; locomotion; Parkinson s disease; aversion; Neuroscience; Neurovetenskap;

    Abstract : The basal ganglia form a group of subcortical interconnected nuclei involved in motor, limbic and cognitive functions. According to the classical model of the basal ganglia, two main pathways exert opposing control over movement, one facilitating movement and the other suppressing movement. READ MORE
