    Notes: Abstract The enzymes oxalate oxidase and peroxidase are encapsulated in stable, optically transparent, porous silica glass matrices synthesized under mild conditions using novel sol-gel synthetic techniques. The large enzymes are immobilized, but smaller molecules such as oxalate ions pass readily through the porous glass. Upon exposure to oxalate solutions, a colored glass is formed whose absorption spectrum and changes of absorbance with time are measured. The sensitivity of the response and the time-dependence of the response are discussed.

    Notes: Abstract The proteins copper-zinc superoxide dismutase (CuZnSOD), cytochrome c, myoglobin, hemoglobin, and bacterio-rhodopsin are encapsulated in stable, optically transparent, porous, silica glass matrices prepared by the sol-gel method such that the biomolecules retain their characteristic reactivities and spectroscopic properties. The resulting glasses allow transport of small molecules into and out of the glasses at reasonable rates but retain the protein molecules within their pores. The transparency of the glasses enables the chemical reactions of the immobilized proteins to be monitored by means of changes in their visible absorption spectra. Silica glasses containing the immobilized proteins have similar reactivities and spectroscopic properties to those found for the proteins in solution. The enzymes glucose oxidase and peroxidase were also encapsulated in transparent silica glass matrices. Upon exposure to glucose solutions, a colored glass is formed that can be used as the active element in a solid state optically based glucose sensor.

    Description: Borna disease virus (BDV) causes a rare neurological disease in horses and sheep. The virus has not been classified because neither an infectious particle nor a specific nucleic acid had been identified. To identify the genome of BDV, a subtractive complementary DNA expression library was constructed with polyadenylate-selected RNA from a BDV-infected MDCK cell line. A clone (B8) was isolated that specifically hybridized to RNA isolated from BDV-infected brain tissue and BDV-infected cell lines. This clone hybridized to four BDV-specific positive strand RNAs (10.5, 3.6, 2.1, and 0.85 kilobases) and one negative strand RNA (10.5 kilobases) in BDV-infected rat brain. Nucleotide sequence analysis of the clone suggested that it represented a full-length messenger RNA which contained several open reading frames. In vitro transcription and translation of the clone resulted in the synthesis of the 14- and 24-kilodalton BDV-specific proteins. The 24-kilodalton protein, when translated in vitro from the clone, was recognized by antibodies in the sera of patients (three of seven) with behavioral disorders. This BDV-specific clone will provide the means to isolate the other BDV-specific nucleic acids and to identify the virus responsible for Borna disease. In addition, the significance of BDV or a BDV-related virus as a human pathogen can now be more directly examined.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉VandeWoude, S -- Richt, J A -- Zink, M C -- Rott, R -- Narayan, O -- Clements, J E -- RR00130/RR/NCRR NIH HHS/ -- RR07002/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1990 Nov 30;250(4985):1278-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Colorado State University, Lab Animal Resources, Fort Collins 80532.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2244211" target="_blank"〉PubMed〈/a〉

    Description: Arising from M. A. Nowak, C. E. Tarnita & E. O. Wilson 466, 1057-1062 (2010); Nowak et al. reply. Nowak et al. argue that inclusive fitness theory has been of little value in explaining the natural world, and that it has led to negligible progress in explaining the evolution of eusociality. However, we believe that their arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature. We will focus our comments on three general issues.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3836173/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3836173/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abbot, Patrick -- Abe, Jun -- Alcock, John -- Alizon, Samuel -- Alpedrinha, Joao A C -- Andersson, Malte -- Andre, Jean-Baptiste -- van Baalen, Minus -- Balloux, Francois -- Balshine, Sigal -- Barton, Nick -- Beukeboom, Leo W -- Biernaskie, Jay M -- Bilde, Trine -- Borgia, Gerald -- Breed, Michael -- Brown, Sam -- Bshary, Redouan -- Buckling, Angus -- Burley, Nancy T -- Burton-Chellew, Max N -- Cant, Michael A -- Chapuisat, Michel -- Charnov, Eric L -- Clutton-Brock, Tim -- Cockburn, Andrew -- Cole, Blaine J -- Colegrave, Nick -- Cosmides, Leda -- Couzin, Iain D -- Coyne, Jerry A -- Creel, Scott -- Crespi, Bernard -- Curry, Robert L -- Dall, Sasha R X -- Day, Troy -- Dickinson, Janis L -- Dugatkin, Lee Alan -- El Mouden, Claire -- Emlen, Stephen T -- Evans, Jay -- Ferriere, Regis -- Field, Jeremy -- Foitzik, Susanne -- Foster, Kevin -- Foster, William A -- Fox, Charles W -- Gadau, Juergen -- Gandon, Sylvain -- Gardner, Andy -- Gardner, Michael G -- Getty, Thomas -- Goodisman, Michael A D -- Grafen, Alan -- Grosberg, Rick -- Grozinger, Christina M -- Gouyon, Pierre-Henri -- Gwynne, Darryl -- Harvey, Paul H -- Hatchwell, Ben J -- Heinze, Jurgen -- Helantera, Heikki -- Helms, Ken R -- Hill, Kim -- Jiricny, Natalie -- Johnstone, Rufus A -- Kacelnik, Alex -- Kiers, E Toby -- Kokko, Hanna -- Komdeur, Jan -- Korb, Judith -- Kronauer, Daniel -- Kummerli, Rolf -- Lehmann, Laurent -- Linksvayer, Timothy A -- Lion, Sebastien -- Lyon, Bruce -- Marshall, James A R -- McElreath, Richard -- Michalakis, Yannis -- Michod, Richard E -- Mock, Douglas -- Monnin, Thibaud -- Montgomerie, Robert -- Moore, Allen J -- Mueller, Ulrich G -- Noe, Ronald -- Okasha, Samir -- Pamilo, Pekka -- Parker, Geoff A -- Pedersen, Jes S -- Pen, Ido -- Pfennig, David -- Queller, David C -- Rankin, Daniel J -- Reece, Sarah E -- Reeve, Hudson K -- Reuter, Max -- Roberts, Gilbert -- Robson, Simon K A -- Roze, Denis -- Rousset, Francois -- Rueppell, Olav -- Sachs, Joel L -- Santorelli, Lorenzo -- Schmid-Hempel, Paul -- Schwarz, Michael P -- Scott-Phillips, Tom -- Shellmann-Sherman, Janet -- Sherman, Paul W -- Shuker, David M -- Smith, Jeff -- Spagna, Joseph C -- Strassmann, Beverly -- Suarez, Andrew V -- Sundstrom, Liselotte -- Taborsky, Michael -- Taylor, Peter -- Thompson, Graham -- Tooby, John -- Tsutsui, Neil D -- Tsuji, Kazuki -- Turillazzi, Stefano -- Ubeda, Francisco -- Vargo, Edward L -- Voelkl, Bernard -- Wenseleers, Tom -- West, Stuart A -- West-Eberhard, Mary Jane -- Westneat, David F -- Wiernasz, Diane C -- Wild, Geoff -- Wrangham, Richard -- Young, Andrew J -- Zeh, David W -- Zeh, Jeanne A -- Zink, Andrew -- BB/H022716/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- England -- Nature. 2011 Mar 24;471(7339):E1-4; author reply E9-10. doi: 10.1038/nature09831.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21430721" target="_blank"〉PubMed〈/a〉
