    The Mars Pathfinder atmospheric structure investigation/meteorology (ASI/MET) experiment (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1997-12-31
    Beschreibung: The Mars Pathfinder atmospheric structure investigation/meteorology (ASI/MET) experiment measured the vertical density, pressure, and temperature structure of the martian atmosphere from the surface to 160 km, and monitored surface meteorology and climate for 83 sols (1 sol = 1 martian day = 24.7 hours). The atmospheric structure and the weather record are similar to those observed by the Viking 1 lander (VL-1) at the same latitude, altitude, and season 21 years ago, but there are differences related to diurnal effects and the surface properties of the landing site. These include a cold nighttime upper atmosphere; atmospheric temperatures that are 10 to 12 degrees kelvin warmer near the surface; light slope-controlled winds; and dust devils, identified by their pressure, wind, and temperature signatures. The results are consistent with the warm, moderately dusty atmosphere seen by VL-1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schofield, J T -- Barnes, J R -- Crisp, D -- Haberle, R M -- Larsen, S -- Magalhaes, J A -- Murphy, J R -- Seiff, A -- Wilson, G -- New York, N.Y. -- Science. 1997 Dec 5;278(5344):1752-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉J.

    The structure of the upper atmosphere of mars: In situ accelerometer measurements from mars global surveyor (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1998-03-25
    Beschreibung: The Mars Global Surveyor (MGS) z-axis accelerometer has obtained over 200 vertical structures of thermospheric density, temperature, and pressure, ranging from 110 to 170 kilometers, compared to only three previous such vertical structures. In November 1997, a regional dust storm in the Southern Hemisphere triggered an unexpectedly large thermospheric response at mid-northern latitudes, increasing the altitude of thermospheric pressure surfaces there by as much as 8 kilometers and indicating a strong global thermospheric response to a regional dust storm. Throughout the MGS mission, thermospheric density bulges have been detected on opposite sides of the planet near 90 degreesE and 90 degreesW, in the vicinity of maximum terrain heights. This wave 2 pattern may be caused by topographically-forced planetary waves propagating up from the lower atmosphere.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keating -- Bougher -- Zurek -- Tolson -- Cancro -- Noll -- Parker -- Schellenberg -- Shane -- Wilkerson -- Murphy -- Hollingsworth -- Haberle -- Joshi -- Pearl -- Conrath -- Smith -- Clancy -- Blanchard -- Wilmoth -- Rault -- Martin -- Lyons -- Esposito -- Johnston -- et -- New York, N.Y. -- Science. 1998 Mar 13;279(5357):1672-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉G.

    Live attenuated malaria vaccine designed to protect through hepatic CD8(+) T cell immunity (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-09-10
    Beschreibung: Our goal is to develop a vaccine that sustainably prevents Plasmodium falciparum (Pf) malaria in 〉/=80% of recipients. Pf sporozoites (PfSPZ) administered by mosquito bites are the only immunogens shown to induce such protection in humans. Such protection is thought to be mediated by CD8(+) T cells in the liver that secrete interferon-gamma (IFN-gamma). We report that purified irradiated PfSPZ administered to 80 volunteers by needle inoculation in the skin was safe, but suboptimally immunogenic and protective. Animal studies demonstrated that intravenous immunization was critical for inducing a high frequency of PfSPZ-specific CD8(+), IFN-gamma-producing T cells in the liver (nonhuman primates, mice) and conferring protection (mice). Our results suggest that intravenous administration of this vaccine will lead to the prevention of infection with Pf malaria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Epstein, J E -- Tewari, K -- Lyke, K E -- Sim, B K L -- Billingsley, P F -- Laurens, M B -- Gunasekera, A -- Chakravarty, S -- James, E R -- Sedegah, M -- Richman, A -- Velmurugan, S -- Reyes, S -- Li, M -- Tucker, K -- Ahumada, A -- Ruben, A J -- Li, T -- Stafford, R -- Eappen, A G -- Tamminga, C -- Bennett, J W -- Ockenhouse, C F -- Murphy, J R -- Komisar, J -- Thomas, N -- Loyevsky, M -- Birkett, A -- Plowe, C V -- Loucq, C -- Edelman, R -- Richie, T L -- Seder, R A -- Hoffman, S L -- 5R44AI055229-07/AI/NIAID NIH HHS/ -- 5R44AI058375-05/AI/NIAID NIH HHS/ -- 5R44AI058499-05/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Oct 28;334(6055):475-80. doi: 10.1126/science.1211548.
