  1. 1. Endoplasmic Reticulum Dynamic Structural Changes in Neurons: The Fission-Fusion Phenomena

    Författare :Krzysztof Kucharz; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fragmentation; fission; endoplasmic reticulum; neurons; FRAP; primary cultures; organotypic slice cultures; in vivo; in situ; calcium; fusion; NMDA receptor; 2-photon microscopy; confocal microscopy;

    Sammanfattning : The endoplasmic reticulum (ER) is crucial for protein synthesis and protein maturation, is involved in cell stress and serves in neurons as the major intracellular Ca2+ store. Neuronal ER forms a continuous network of cisterns and tubules extending from soma to a subset of dendritic spines. LÄS MER

  2. 2. Auditory organotypic cultures and progenitor cell implantation

    Författare :Andreas Kaiser; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : According to the WHO, about 5 % of the world’s population suffers from disabling hearing loss. In people above the age of 65 the number is more than 30 %. Common effects of this condition are poor speech discrimination and impaired communication abilities. Patient surveys show that hearing loss often leads to a diminished quality of life. LÄS MER

  3. 3. Mechanisms of Ischemic Brain Injury- studies in murine hippocampal slice cultures

    Författare :Anna Rytter; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; Neurologi; neuropsykologi; neuropsychology; Neurology; adenosine; caspases; hypothermia; in vitro; hippocampus; ischemia; neurofysiologi;

    Sammanfattning : Cerebral ischemia is a major cause of mortality and morbidity in the western world. Even though much effort has been put into research and development of effective drugs against ischemic damage there is to date no effective pharmacological brain protective treatment. LÄS MER

  4. 4. Characterization of hippocampal slice cultures as model systems for neurodegenerative processes in Alzheimer's disease

    Författare :Sara Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer's disease (AD) is the most common cause of dementia and a growing health care problem worldwide. The disease affects different brain regions, including hippocampus, enthorhinal cortex, amygdala, neocortex and certain basal forebrain nuclei. Macroscopically, shrinkage of gyri and widening of sulci characterize the AD brain. LÄS MER

  5. 5. Interaction between nerve fiber formation and astrocytes

    Författare :Sanazalsadat Hashemian; Ingrid Strömberg; Elisabet Åkesson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dopamine; nerve fiber outgrowth; astrocytes; ventral mesencephalon; spinal cord; CSPG; CD47;

    Sammanfattning : Parkinson’s disease, the second most common neurodegenerative disorder,is characterized by loss of nigrostriatal dopaminergic neurons. To date,there is no defined cause and cure for the disease. An ideal treatmentstrategy is to replace the lost neurons by transplanting fetal dopaminergicneurons to the brain of parkinsonian patients.
