Full text linkUn metodo per la diagnosi , il monitoraggio dell'efficacia di una terapia e per lo sviluppo di un trattamento per la Sclerosi Multipla Method for diagnosis, monitoring the efficacy of a therapy and for development of treatment for Multiple Sclerosis
No full textThe present invention relates to a method for diagnosis and/or prognosis of multiple sclerosis or to monitor the efficacy of a therapy and/or to screen for a treatment for multiple sclerosis comprising measuring the amount or assessing the cellular localization of one or more specific molecular species in stimulated oligodendrocyte cells. Changes of expression or localization of specific proteins involved in oligodendrocyte differentiation are measured after incubation of differentiating cells with cerebrospinal fluid, immunoglobulins extracted from blood serum or blood of patients with multiple sclerosis
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
THE CALF SUPEROXIDE-DISMUTASE RECEPTOR OF RAT HEPATOCYTES
No full textThe presence of a specific SOD surface membrane receptor in rat hepatocyte cells was investigated using ligand blot analysis of the SOD receptor with 125I-SOD, and binding studies with iodinated and fluorescinated SOD. A specific SOD receptor with a molecular weight of about 320 kDa was identified. We suggest that the modulatory role of SOD on HMG-CoA reductase is exerted through this specific receptor. © 1994
SECRETION AND INCREASE OF INTRACELLULAR CuZn SUPEROXIDE DISMUTASE CONTENT IN HUMAN NEUROBLASTOMA SK-N-BE CELLS SUBJECTED TO OXIDATIVE STRESS
No full textCuZn superoxide dismutase (SOD) secretion was detected in media of [S-35]cysteine-labeled human neuroblastoma SK-N-BE cells precipitated with antihuman CuZn SOD antibodies. The ability of Fe2+/ascorbate oxidative stress to induce CuZn SOD in SK-N-BE cells was evaluated by Western blot analysis. The results showed that, like human hepatocarcinoma cells and human fibroblasts, SK-N-BE cells secrete CuZn SOD. In addition, the CuZn SOD concentration was higher in cells subjected to oxidative stress than in unstressed cells. The secretion of CuZn SOD and the ability of Fe2+/ascorbate to increase its protein content in SK-N-BE cells indicates that this enzyme protects the brain from damage induced by oxidative stress.
