    Spatial patterns in the distribution of tropical tree species (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-05-29
    Description: Fully mapped tree census plots of large area, 25 to 52 hectares, have now been completed at six different sites in tropical forests, including dry deciduous to wet evergreen forest on two continents. One of the main goals of these plots has been to evaluate spatial patterns in tropical tree populations. Here the degree of aggregation in the distribution of 1768 tree species is examined based on the average density of conspecific trees in circular neighborhoods around each tree. When all individuals larger than 1 centimeter in stem diameter were included, nearly every species was more aggregated than a random distribution. Considering only larger trees (〉/= 10 centimeters in diameter), the pattern persisted, with most species being more aggregated than random. Rare species were more aggregated than common species. All six forests were very similar in all the particulars of these results.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Condit, R -- Ashton, P S -- Baker, P -- Bunyavejchewin, S -- Gunatilleke, S -- Gunatilleke, N -- Hubbell, S P -- Foster, R B -- Itoh, A -- LaFrankie, J V -- Lee, H S -- Losos, E -- Manokaran, N -- Sukumar, R -- Yamakura, T -- New York, N.Y. -- Science. 2000 May 26;288(5470):1414-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Tropical Forest Science, Smithsonian Tropical Research Institute, Unit 0948, APO AA 34002-0948, USA. ctfs@tivoli.si.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10827950" target="_blank"〉PubMed〈/a〉

    Linkage of plasma Abeta42 to a quantitative locus on chromosome 10 in late-onset Alzheimer's disease pedigrees (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-12-23
    Description: Plasma Abeta42 (amyloid beta42 peptide) is invariably elevated in early-onset familial Alzheimer's disease (AD), and it is also increased in the first-degree relatives of patients with typical late-onset AD (LOAD). To detect LOAD loci that increase Abeta42, we used plasma Abeta42 as a surrogate trait and performed linkage analysis on extended AD pedigrees identified through a LOAD patient with extremely high plasma Abeta. Here, we report linkage to chromosome 10 with a maximal lod score of 3.93 at 81 centimorgans close to D10S1225. Remarkably, linkage to the same region was obtained independently in a genome-wide screen of LOAD sibling pairs. These results provide strong evidence for a novel LOAD locus on chromosome 10 that acts to increase Abeta.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ertekin-Taner, N -- Graff-Radford, N -- Younkin, L H -- Eckman, C -- Baker, M -- Adamson, J -- Ronald, J -- Blangero, J -- Hutton, M -- Younkin, S G -- AG06656/AG/NIA NIH HHS/ -- MH59490/MH/NIMH NIH HHS/ -- P50 AG16574/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2000 Dec 22;290(5500):2303-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mayo Clinic Jacksonville, Jacksonville, FL 32224, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11125143" target="_blank"〉PubMed〈/a〉

    Molecular biology. Transposase team puts a headlock on DNA (2000)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 2000-08-06
    Description: Transposable DNA elements jump from one location in the genome to another. But, the cut-and-paste molecular machinations that support this nomadic lifestyle are still being unraveled. In their Perspective, Williams and Baker at the Massachusetts Institute of Technology discuss new details of transposon relocation revealed through resolution of the structure of a transposase enzyme bound to DNA (Davies et al.).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, T L -- Baker, T A -- New York, N.Y. -- Science. 2000 Jul 7;289(5476):73-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Office 68-517, Massachusetts Institute of Technology, Cambridge, MA 02139, USA. tlwillia@mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10928934" target="_blank"〉PubMed〈/a〉

    A specificity-enhancing factor for the ClpXP degradation machine (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-09-29
    Description: Events that stall bacterial protein synthesis activate the ssrA-tagging machinery, resulting in resumption of translation and addition of an 11-residue peptide to the carboxyl terminus of the nascent chain. This ssrA-encoded peptide tag marks the incomplete protein for degradation by the energy-dependent ClpXP protease. Here, a ribosome-associated protein, SspB, was found to bind specifically to ssrA-tagged proteins and to enhance recognition of these proteins by ClpXP. Cells with an sspB mutation are defective in degrading ssrA-tagged proteins, demonstrating that SspB is a specificity-enhancing factor for ClpXP that controls substrate choice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levchenko, I -- Seidel, M -- Sauer, R T -- Baker, T A -- AI-16892/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2000 Sep 29;289(5488):2354-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology and Howard Hughes Medical Institute, Building 68, Room 523, Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11009422" target="_blank"〉PubMed〈/a〉

    Hydrological characterisation of stalagmite dripwaters at Grotte de Villars, Dordogne, by the analysis of inorganic species and luminescent organic matter (2000)
    Copernicus
    Details
    Publication Date: 2000-09-30
    Description: Five stalagmite drip-waters in the Grotte de Villars, Dordogne, have been monitored from early 1997 to early 1998, for variations in discharge, major inorganic species and dissolved luminescent organic matter. When compared to surface precipitation, each drip-water has a subtly different response, both in terms of discharge variability and lag time between surface precipitation and drip rate response. Calculated water excess is shown to be important in determining drip-water discharge; during periods of soil moisture deficit, drip-waters either show no response to surface precipitation, or in the case of one sample station, respond only to high intensity and/or high quantity precipitation events. All drip-waters have a large storage component to their flow. Four sample stations have a similar hydrochemical and luminescence response, although the precise timing and magnitude of the responses may vary between drip sources that are
