Publication Opinion Polarization during a Dichotomous Electoral Process(2019-02-10) ;G. Olivares ;J. P. Cárdenas ;J. C. LosadaJ. BorondoPolitical polarization can emerge on electoral campaigns where the population faces a dichotomous decision, with only two voting alternatives. In this paper, we analyze the Twitter conversation around the second round of the 2017 Chilean elections, where voters had to choose between the final two candidates. First, we have estimated the opinions of Twitter users obtaining a distribution of opinions for each day. Next, we have measured the resulting political polarization from the cited opinion distributions and track its evolution during a full week that includes the voting day. We found the conversation to be highly polarized, reaching its maximum during the previous day to the election and significantly decreasing the day after due to the presence of new users who only participated during that day. - Some of the metrics are blocked by yourconsent settings
Publication Technical-legal management standards for digital legislative information services,Estándares técnico-jurídicos de gestión para servicios digitales de información legislativa(2017)Reyes Olmedo, P.A challenge of rule of Law is to provide access to the contents of legal texts under modern information management standards for its efficient and effective storage, processing, search, retrieval and communication. The article reviews the international standards for digital legislative information services. The author proposes that the legislative semantic web, based on the technologies of structured document (XML), metadata (RDF) and ontologies (OWL) appears as the optimal platform model for the representation, organization and distribution of these legal contents, and is an effective response to the requirements caused by the phenomenon of legislative contamination and the demand for better and easier access to legislation. - Some of the metrics are blocked by yourconsent settings
Publication Zoledronic Acid Modulation of TRPV1 Channel Currents in Osteoblast Cell Line and Native Rat and Mouse Bone Marrow-Derived Osteoblasts: Cell Proliferation and Mineralization Effect(2019-02-11) ;Rosa Scala ;Fatima Maqoud ;Mariacristina Angelelli ;Ramon Latorre ;Maria Grazia Perrone ;Antonio ScilimatiDomenico TricaricoBisphosphonates (BPs) reduce bone pain and fractures by balancing the osteoblast/osteoclast ratio. The behavior of ion channels in the presence of BPs is not known. To investigate this, the effect of zoledronic acid BP (ZOL) (3 × 10−8 to 5 × 10−4 M) treatment, on ion channels, cell proliferation, and mineralization, has been investigated on preosteoclast-like cells, RAW264.7, preosteoblast-like cells MC3T3-E1, and rat/mouse native bone marrow-derived osteoblasts. In whole-cell patch clamp on cell line- and bone marrow-derived osteoblasts, ZOL potentiated outward currents. On RAW264.7, ZOL (10−4 M)-evoked current was reduced by the Kv channel blocker tetraethylammonium hydrochloride (TEA), but not by the selective TRPV1-channel antagonist capsazepine. On MC3T3-E1 cells and bone marrow-derived osteoblasts, ZOL-evoked current (5 × 10−8 to 10−4 M) was reduced by capsazepine, whereas the selective TRPV1-channel agonist capsaicin potentiated the control current. In the cell proliferation assay, 72 h incubation of RAW264.7 and MC3T3-E1 cells with ZOL reduced proliferation, with IC50 values of 2.62 × 10−7 M and 2.02 × 10−5 M, respectively. Mineralization of MC3T3-E1 cells and bone marrow-derived osteoblasts was observed in the presence of capsaicin and ZOL (5 × 10−8–10−7 M); ZOL effects were antagonized by capsazepine. In summary, the ZOL-induced activation of TRPV1 channel mediates the mineralization of osteoblasts and counterbalances the antiproliferative effects, increasing the IC50. This mechanism is not operative in osteoclasts lacking the TRPV1 channel.
