    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: The use of an image registration program in the studies of urban growth is described. This program permits a quick identification of growing areas with the overlap of the same scene in different periods, and with the use of adequate filters. The city of Brasilia, Brazil, is selected for the test area. The dynamics of Brasilia urban growth are analyzed with the overlap of scenes dated June 1973, 1978 and 1983. The results showed the utilization of the image registration technique for the monitoring of dynamic urban growth.

    Application of LANDSAT data to the study of urban development in Brasilia (1984)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: The urban growth of Brasilia within the last ten years is analyzed with special emphasis on the utilization of remote sensing orbital data and automatic image processing. The urban spatial structure and the monitoring of its temporal changes were examined in a whole and dynamic way by the utilization of MSS-LANDSAT images for June (1973, 1978 and 1983). In order to aid data interpretation, a registration algorithm implemented in the Interactive Multispectral Image Analysis System (IMAGE-100) was utilized aiming at the overlap of multitemporal images. The utilization of suitable digital filters, combined with the images overlap, allowed a rapid identification of areas of possible urban growth and oriented the field work. The results obtained in this work permitted an evaluation of the urban growth of Brasilia, taking as reference the proposal stated for the construction of the city in the Pilot Plan elaborated by Lucio Costa.

    Identification of alpha-dystroglycan as a receptor for lymphocytic choriomeningitis virus and Lassa fever virus (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-12-16
    Description: A peripheral membrane protein that is interactive with lymphocytic choriomeningitis virus (LCMV) was purified from cells permissive to infection. Tryptic peptides from this protein were determined to be alpha-dystroglycan (alpha-DG). Several strains of LCMV and other arenaviruses, including Lassa fever virus (LFV), Oliveros, and Mobala, bound to purified alpha-DG protein. Soluble alpha-DG blocked both LCMV and LFV infection. Cells bearing a null mutation of the gene encoding DG were resistant to LCMV infection, and reconstitution of DG expression in null mutant cells restored susceptibility to LCMV infection. Thus, alpha-DG is a cellular receptor for both LCMV and LFV.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cao, W -- Henry, M D -- Borrow, P -- Yamada, H -- Elder, J H -- Ravkov, E V -- Nichol, S T -- Compans, R W -- Campbell, K P -- Oldstone, M B -- AG 00080/AG/NIA NIH HHS/ -- AI 09484/AI/NIAID NIH HHS/ -- DK09712/DK/NIDDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1998 Dec 11;282(5396):2079-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Virology, Department of Neuropharmacology, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9851928" target="_blank"〉PubMed〈/a〉

    Differential clustering of CD4 and CD3zeta during T cell recognition (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-08-26
    Description: Whereas T helper cells recognize peptide-major histocompatibility complex (MHC) class II complexes through their T cell receptors (TCRs), CD4 binds to an antigen-independent region of the MHC. Using green fluorescent protein-tagged chimeras and three-dimensional video microscopy, we show that CD4 and TCR-associated CD3zeta cluster in the interface coincident with increases in intracellular calcium. Signaling-, costimulation-, and cytoskeleton-dependent processes then stabilize CD3zeta in a single cluster at the center of the interface, while CD4 moves to the periphery. Thus, the CD4 coreceptor may serve primarily to "boost" recognition of ligand by the TCR and may not be required once activation has been initiated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krummel, M F -- Sjaastad, M D -- Wulfing, C -- Davis, M M -- New York, N.Y. -- Science. 2000 Aug 25;289(5483):1349-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Stanford University School of Medicine, and the Howard Hughes Medical Institute, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10958781" target="_blank"〉PubMed〈/a〉

    Transcriptional regulation of cortical neuron migration by POU domain factors (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-02-23
    Description: The identification of pathways mediated by the kinase Cdk5 and the ligand reelin has provided a conceptual framework for exploring the molecular mechanisms underlying proper lamination of the developing mammalian cerebral cortex. In this report, we identify a component of the regulation of Cdk5-mediated cortical lamination by genetic analysis of the roles of the class III POU domain transcription factors, Brn-1 and Brn-2, expressed during the development of the forebrain and coexpressed in most layer II-V cortical neurons. Brn-1 and Brn-2 appear to critically control the initiation of radial migration, redundantly regulating the cell-autonomous expression of the p35 and p39 regulatory subunits of Cdk5 in migrating cortical neurons, with Brn-1(-/-)/Brn-2(-/-) mice exhibiting cortical inversion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McEvilly, Robert J -- de Diaz, Marcela Ortiz -- Schonemann, Marcus D -- Hooshmand, Farideh -- Rosenfeld, Michael G -- New York, N.Y. -- Science. 2002 Feb 22;295(5559):1528-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department and School of Medicine, University of California, San Diego, 9500 Gilman Drive, La Jolla, CA 92037-0648, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11859196" target="_blank"〉PubMed〈/a〉

    Processing of the notch ligand delta by the metalloprotease Kuzbanian (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-01-05
    Description: Signaling by the Notch surface receptor controls cell fate determination in a broad spectrum of tissues. This signaling is triggered by the interaction of the Notch protein with what, so far, have been thought to be transmembrane ligands expressed on adjacent cells. Here biochemical and genetic analyses show that the ligand Delta is cleaved on the surface, releasing an extracellular fragment capable of binding to Notch and acting as an agonist of Notch activity. The ADAM disintegrin metalloprotease Kuzbanian is required for this processing event. These observations raise the possibility that Notch signaling in vivo is modulated by soluble forms of the Notch ligands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Qi, H -- Rand, M D -- Wu, X -- Sestan, N -- Wang, W -- Rakic, P -- Xu, T -- Artavanis-Tsakonas, S -- NS14841/NS/NINDS NIH HHS/ -- NS26084/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1999 Jan 1;283(5398):91-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Yale University School of Medicine, Boyer Center for Molecular Medicine, 295 Congress Avenue, New Haven, CT 06536-0812, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9872749" target="_blank"〉PubMed〈/a〉

    Communication of the position of exon-exon junctions to the mRNA surveillance machinery by the protein RNPS1 (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-09-08
    Description: In mammalian cells, splice junctions play a dual role in mRNA quality control: They mediate selective nuclear export of mature mRNA and they serve as a mark for mRNA surveillance, which subjects aberrant mRNAs with premature termination codons to nonsense-mediated decay (NMD). Here, we demonstrate that the protein RNPS1, a component of the postsplicing complex that is deposited 5' to exon-exon junctions, interacts with the evolutionarily conserved human Upf complex, a central component of NMD. Significantly, RNPS1 triggers NMD when tethered to the 3' untranslated region of beta-globin mRNA, demonstrating its role as a subunit of the postsplicing complex directly involved in mRNA surveillance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lykke-Andersen, J -- Shu, M D -- Steitz, J A -- CA 16038/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2001 Sep 7;293(5536):1836-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Molecular Biochemistry and Biophysics, Yale University School of Medicine, 295 Congress Avenue, New Haven, CT 06536, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11546874" target="_blank"〉PubMed〈/a〉
