    Applications of gene therapy to the CNS

    No full text
    Gene therapy is a new method with potential far treating a broad range of acquired and inherited neurologic diseases, where the causative gene defect or deletion has been identified. In addition to gene replacement the application of gene products that reduce cellular dysfunction or death represent new therapeutic options. Gene transfer techniques to express novel proteins using different viral vectors in vitro and in vivo, as well as animal models and human trials will be reviewed in this article. We will focus on a new lentiviral vector as a recent gene transfer method and degenerative disorders of the CNS, and their related model systems

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
