  • Trypanosoma rangeli and Trypanosoma cruzi : molecular characterization of genes encoding putative calcium-binding proteins, highly conserved in typanosomatids

    • Genes encoding a 29-kDa flagellar calcium-binding protein (F29) in Trypanosoma cruzi, strongly homologous to EF-hand calcium-binding protein-encoding genes previously reported in this parasite, were isolated by immunoscreening. F29 is encoded by a number of very similar genes, highly conserved among different T. cruzi isolates. The genes are located on a pair of homologous chromosomes, arranged in one or two clusters of tandem repeats. PCR amplification of Trypanosoma rangeli genomic DNA, using primers derived from the T. cruzi F29 sequence made it possible to isolate the homologous gene in T. rangeli, encoding a 23-kDa protein called TrCaBP. Gene sequence comparisons showed homology to EF-hand calcium-binding proteins from T. cruzi (82.8%), Trypanosoma brucei brucei (60.2%), and Entamoeba histolytica (28.4%). Northern blot analysis revealed that the TrCaBP gene is expressed in T. rangeli as a polyadenylated transcript. The TrCaBP-encoding genes are present in at least 20 copies per cell, organized in tandem arrays, on large T. rangeli chromosomes in some isolates and on two smaller ones in others. This gene, however, seems to be absent from Leishmania.

  • Multi Modal Verification for Teleservices and Security Applications (M2VTS)
  • 1999
  • Ingår i: IEEE International Conference on Multimedia Computing and Systems. - Los Alamitos : IEEE. - 0769502539 ; , s. 1061-1064
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • This paper presents the European ACTS project M2VTS which stands for Multi Modal Verification for Teleservices and Security Applications. The primary goal of this project is to address the issue of secured access to local and centralised services in a multimedia environment. The main objective is to extend the scope of application of network-based services by adding novel and intelligent functionalities, enabled by automatic verification systems combining multimodal strategies (secured access based on speech, image or other information). The objectives of the project are also to show that limitations of individual technologies (speaker verification, frontal face authentication, profile identification,...) can be overcome by relying on multi-modal decisions (combination or fusion of these technologies).
