    Inhibition of a Mycobacterium tuberculosis beta-ketoacyl ACP synthase by isoniazid (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1998-06-11
    Beschreibung: Although isoniazid (isonicotinic acid hydrazide, INH) is widely used for the treatment of tuberculosis, its molecular target has remained elusive. In response to INH treatment, saturated hexacosanoic acid (C26:0) accumulated on a 12-kilodalton acyl carrier protein (AcpM) that normally carried mycolic acid precursors as long as C50. A protein species purified from INH-treated Mycobacterium tuberculosis was shown to consist of a covalent complex of INH, AcpM, and a beta-ketoacyl acyl carrier protein synthase, KasA. Amino acid-altering mutations in the KasA protein were identified in INH-resistant patient isolates that lacked other mutations associated with resistance to this drug.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mdluli, K -- Slayden, R A -- Zhu, Y -- Ramaswamy, S -- Pan, X -- Mead, D -- Crane, D D -- Musser, J M -- Barry, C E 3rd -- AI37004/AI/NIAID NIH HHS/ -- Z01 AI000783-11/Intramural NIH HHS/ -- New York, N.Y. -- Science. 1998 Jun 5;280(5369):1607-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tuberculosis Research Unit, Laboratory of Intracellular Parasites, Rocky Mountain Laboratories, National Institute for Allergy and Infectious Diseases (NIAID), National Institutes of Health, Hamilton, MT 59840, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9616124" target="_blank"〉PubMed〈/a〉

    Time-critical social mobilization (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-10-29
    Beschreibung: The World Wide Web is commonly seen as a platform that can harness the collective abilities of large numbers of people to accomplish tasks with unprecedented speed, accuracy, and scale. To explore the Web's ability for social mobilization, the Defense Advanced Research Projects Agency (DARPA) held the DARPA Network Challenge, in which competing teams were asked to locate 10 red weather balloons placed at locations around the continental United States. Using a recursive incentive mechanism that both spread information about the task and incentivized individuals to act, our team was able to find all 10 balloons in less than 9 hours, thus winning the Challenge. We analyzed the theoretical and practical properties of this mechanism and compared it with other approaches.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pickard, Galen -- Pan, Wei -- Rahwan, Iyad -- Cebrian, Manuel -- Crane, Riley -- Madan, Anmol -- Pentland, Alex -- New York, N.Y. -- Science. 2011 Oct 28;334(6055):509-12. doi: 10.1126/science.1205869.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Media Laboratory, Massachusetts Institute of Technology (MIT), Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22034432" target="_blank"〉PubMed〈/a〉

    Vertebrate cell cycle modulates infection by protozoan parasites (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1981-11-27
    Beschreibung: Synchronized HeLa cell populations were exposed to Trypanosoma cruzi or Toxoplasma gondii, obligate intracellular protozoan parasites that cause Chagas' disease and toxoplasmosis, respectively, in humans. The ability of the two parasites to infect HeLa cells increased as the HeLa cells proceeded from the G1 phase to the S phase of their growth cycle and decreased as the cells entered G2-M. Characterization of the S-phase cell surface components responsible for this phenomenon could be beneficial in the development of vaccines against these parasitic diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dvorak, J A -- Crane, M S -- New York, N.Y. -- Science. 1981 Nov 27;214(4524):1034-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7029713" target="_blank"〉PubMed〈/a〉
