    Comment on "Calcareous nannoplankton response to surface-water acidification around Oceanic Anoxic Event 1a" (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-04-09
    Description: Erba et al. (Reports, 23 July 2010, p. 428) attributed calcareous nannofossil morphology and assemblage changes across Cretaceous Oceanic Anoxic Event 1a to the effects of surface ocean acidification. We argue that the quality of carbonate preservation in these sequences, the unsupported assumptions of the biotic response to acidity, and the absence of independent proxy estimates for ocean pH or atmospheric pCO(2) render this conclusion questionable.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gibbs, Samantha J -- Robinson, Stuart A -- Bown, Paul R -- Jones, Tom Dunkley -- Henderiks, Jorijntje -- New York, N.Y. -- Science. 2011 Apr 8;332(6026):175; author reply 175. doi: 10.1126/science.1199459.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Ocean and Earth Sciences, National Oceanography Centre, Southampton, European Way, Southampton, SO14 3ZH, UK. sxg@noc.soton.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21474738" target="_blank"〉PubMed〈/a〉

    Nannoplankton extinction and origination across the Paleocene-Eocene Thermal Maximum (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-16
    Description: The Paleocene-Eocene Thermal Maximum (PETM, approximately 55 million years ago) was an interval of global warming and ocean acidification attributed to rapid release and oxidation of buried carbon. We show that the onset of the PETM coincided with a prominent increase in the origination and extinction of calcareous phytoplankton. Yet major perturbation of the surface-water saturation state across the PETM was not detrimental to the survival of most calcareous nannoplankton taxa and did not impart a calcification or ecological bias to the pattern of evolutionary turnover. Instead, the rate of environmental change appears to have driven turnover, preferentially affecting rare taxa living close to their viable limits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gibbs, Samantha J -- Bown, Paul R -- Sessa, Jocelyn A -- Bralower, Timothy J -- Wilson, Paul A -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1770-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Ocean and Earth Sciences, National Oceanography Centre, Southampton, European Way, Southampton, SO14 3ZH, UK. sxg@noc.soton.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170303" target="_blank"〉PubMed〈/a〉

    Intraneuronal aluminum accumulation in amyotrophic lateral sclerosis and Parkinsonism-dementia of Guam (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-09-10
    Description: Scanning electron microscopy with energy-dispersive x-ray spectrometry was used to analyze the elemental content of neurofibrillary tangle (NFT)-bearing and NFT-free neurons within the Sommer's sector (H1 region) of the hippocampus in Guamanian Chamorros with amyotrophic lateral sclerosis and parkinsonism-dementia and in neurologically normal controls. Preliminary data indicate prominent accumulation of aluminum within the nuclear region and perikaryal cytoplasm of NFT-bearing hippocampal neurons, regardless of the underlying neurological diagnosis. These findings further extend the association between intraneuronal aluminum and NFT formation and support the hypothesis that environmental factors are related to the neurodegenerative changes seen in the Chamorro population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perl, D P -- Gajdusek, D C -- Garruto, R M -- Yanagihara, R T -- Gibbs, C J -- AG-01415/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1982 Sep 10;217(4564):1053-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7112111" target="_blank"〉PubMed〈/a〉

    Measles virus nucleotide sequences: detection by hybridization in situ (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-05-08
    Description: A tritium-labeled probe that detects measles virus nucleotide sequences was hybridized in situ to cells infected with measles virus and to sections of brain tissue from patients with subacute sclerosing panencephalitis and from patients with multiple sclerosis. The measles virus genome was detected in many cells in subacute sclerosing panencephalitis where this virus would have been missed by methods such as immunofluorescence. Measles virus sequences were also found in two foci in one of four cases of multiple sclerosis. This refined method of hybridization in situ, which can be useful in the search for covert virus infections of man, provides evidence that viruses may be involved in multiple sclerosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haase, A T -- Ventura, P -- Gibbs, C J Jr -- Tourtellotte, W W -- New York, N.Y. -- Science. 1981 May 8;212(4495):672-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7221554" target="_blank"〉PubMed〈/a〉
