  2. 1. The chloroplast talks : Insights into the language of the chloroplast in Arabidopsis

    Author : Peter Kindgren; Åsa Strand; Barry Pogson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; photosynthesis; retrograde communication; Mg-ProtoIX; oxidative stress; gene expression; Molecular biology; Molekylärbiologi; Physiological Botany; fysiologisk botanik;

    Abstract : The chloroplast originates from an endosymbiotic event 1.5 billion years ago, when a free living photosynthetic bacteria was engulfed by a eukaryotic host. The chloroplastic genome has through evolution lost many genes to the nuclear genome of the host. READ MORE

  4. 2. Coordination of two different genomes in response to light and stress

    Author : Louise Norén Lindbäck; Åsa Strand; Antony Dodd; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; cellular communication; tetrapyrrole; circadian clock; oxidative stress; light signalling; gene regulation; molekylärbiologi; Molecular Biology;

    Abstract : About 1.5 billion years ago, a photosynthetic bacteria was engulfed by a eukaryotic cell which initiated a symbiotic relationship and the evolution of the chloroplast as we know it today. The chloroplast has retained its own genome encoding for a number of proteins required for the function of the chloroplast. READ MORE

  5. 3. Synaptic plasticity in local networks of neocortical layer 2/3

    Author : Misha Zilberter; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Neocortical microcircuit; layer 2 3; pyramidal cell; spike timing- dependent plasticity; LTP; LTD; FSN interneuron; retrograde signalling; SAT2;

    Abstract : The neocortex is a hierarchal organ in which information processing takes on place on many levels, from subcellular signalling all the way to neural networks. Neocortical local neuronal networks (microcircuits), composed of interconnected neurons, form elementary information processing units within the cortex. READ MORE

  6. 4. Specificity of neurotrophins in the nervous system : a genetic approach to determine receptor engagement by neurotrophins

    Author : Karin Agerman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The classical neurotrophic factor hypothesis describes the neurotrophins as retrograde signalling factors supporting the survival of postmitotic neurons during the development. Knock-out mice for the neurotrophins and/or their receptors have been generated and their analyses gave new insights in the temporal expression and particular functions of these factors during development.

  7. 5. Propofol changes the cytoskeletal function in neurons : An experimental study in cortical cultures

    Author : Dean Turina; Christina Eintrei; Karin Björnström Karlsson; Lindahl Sten; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Propofol; cytoskeleton;

    Abstract : Every day, general anaesthetics are given to a large number of patients around the world but the cellular mechanisms of how anaesthetics act are still not clear. General anaesthetics cause the intended unconsciousness, amnesia and immobility in patients, but also side effects such as a decrease in mean arterial pressure and arrhythmia, both of which contribute to complications such as heart damage and stroke.
