  2. 1. Pituitary adenylate cyclase activating polypeptide : Expression and neurotrophic activity in the rat brain

    Author : Ylva Skoglösa; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; in situ hybridisation; rat; TBI; BDNF; NGF; GDNF; PACAP; PRI; TUNEL; apoptosis; CNS; PNS; neuropeptides; neurotrophic factors; reactive oxygen species; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Abstract : Neurotrophic factors play an important role in regulating naturally occurring cell death during neurogenesis. In addition to classical neurotrophic factors, some neurotransmitters and neuropeptides have been shown to exhibit neurotrophic activities. READ MORE

  4. 2. Neutrino interactions and axion emission impact on core-collapse supernova simulations

    Author : Aurore Betranhandy; Evan O'Connor; Jeremiah Murphy; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Core-Collapse Supernovae; simulations; CCSN; PNS; neutrino; axion; Astronomy; astronomi;

    Abstract : Core-Collapse Supernovae (CCSNe) are important phenomena in the scope of nucleosynthesis and, as the final stage of massive stars' life, they are key processes in the understanding of stellar evolution. They also are the birthplace of neutron stars and black holes, therefore they play a major role in the modelling and understanding of compact object mergers. READ MORE

  5. 3. Neural Stem and Progenitor Cells as a Tool for Tissue Regeneration

    Author : Ulrika Wallenquist; Karin Forsberg Nilsson; Lars Hillered; Karin Holmqvist; Anders Lewén; Johan Bengzon; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; neural stem cells; transplantation; CNS; PNS; progenitor cells; inflammation; CCI; Biochemistry; Biokemi; Neurosurgery; neurokirurgi; Medical Biochemistry; medicinsk biokemi;

    Abstract : Neural stem and progenitor cells (NSPC) can differentiate to neurons and glial cells. NSPC are easily propagated in vitro and are therefore an attractive tool for tissue regeneration. Traumatic brain injury (TBI) is a common cause for death and disabilities. A fundamental problem following TBI is tissue loss. READ MORE

  6. 4. Reconnecting the CNS and PNS with Stem Cell Transplantation

    Author : Niclas König; Elena Kozlova; Peter Richardson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stem cell transplantation; regenerative neurobiology; nerve injury repair; Medical Science; Medicinsk vetenskap;

    Abstract : Severe injury may result in disconnection between the peripheral and central nervous system. Regeneration of the central portion of sensory neurons into the spinal cord is notoriously poor in adult mammals, with low regenerative drive and an unpermissive central environment, most likely resulting in persistent loss of sensory function.

  7. 5. A screen for mutations affecting PNS development in Drosophila identifies the trim gene, dappled

    Author : Fergal O'Farrell; Per Kylsten; Jan-Åke Gustafsson; Stefan Thor; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The peripheral nervous system of Drosophila melanogaster contains a variety of sense organs, ranging from the relatively simple four celled bristle organ to the more complex compound eye. The development of each organ type is well described, providing a useful backdrop for functional studies of genes acting in one or more of the many processes involved in organogenesis. READ MORE
