    Strange magnetism and the anapole structure of the proton (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-01-11
    Description: The violation of mirror symmetry in the weak force provides a powerful tool to study the internal structure of the proton. Experimental results have been obtained that address the role of strange quarks in generating nuclear magnetism. The measurement reported here provides an unambiguous constraint on strange quark contributions to the proton's magnetic moment through the electron-proton weak interaction. We also report evidence for the existence of a parity-violating electromagnetic effect known as the anapole moment of the proton. The proton's anapole moment is not yet well understood theoretically, but it could have important implications for precision weak interaction studies in atomic systems such as cesium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hasty, R -- Hawthorne-Allen, A M -- Averett, T -- Barkhuff, D -- Beck, D H -- Beise, E J -- Blake, A -- Breuer, H -- Carr, R -- Covrig, S -- Danagoulian, A -- Dodson, G -- Dow, K -- Farkhondeh, M -- Filippone, B W -- Gao, J -- Herda, M C -- Ito, T M -- Jones, C E -- Korsch, W -- Kramer, K -- Kowalski, S -- Lee, P -- McKeown, R D -- Mueller, B -- Pitt, M -- New York, N.Y. -- Science. 2000 Dec 15;290(5499):2117-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physics, University of Illinois at Urbana-Champaign, Urbana, IL 61801, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11118140" target="_blank"〉PubMed〈/a〉

    The Chlamydomonas genome reveals the evolution of key animal and plant functions (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-13
    Description: Chlamydomonas reinhardtii is a unicellular green alga whose lineage diverged from land plants over 1 billion years ago. It is a model system for studying chloroplast-based photosynthesis, as well as the structure, assembly, and function of eukaryotic flagella (cilia), which were inherited from the common ancestor of plants and animals, but lost in land plants. We sequenced the approximately 120-megabase nuclear genome of Chlamydomonas and performed comparative phylogenomic analyses, identifying genes encoding uncharacterized proteins that are likely associated with the function and biogenesis of chloroplasts or eukaryotic flagella. Analyses of the Chlamydomonas genome advance our understanding of the ancestral eukaryotic cell, reveal previously unknown genes associated with photosynthetic and flagellar functions, and establish links between ciliopathy and the composition and function of flagella.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875087/" 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/PMC2875087/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Merchant, Sabeeha S -- Prochnik, Simon E -- Vallon, Olivier -- Harris, Elizabeth H -- Karpowicz, Steven J -- Witman, George B -- Terry, Astrid -- Salamov, Asaf -- Fritz-Laylin, Lillian K -- Marechal-Drouard, Laurence -- Marshall, Wallace F -- Qu, Liang-Hu -- Nelson, David R -- Sanderfoot, Anton A -- Spalding, Martin H -- Kapitonov, Vladimir V -- Ren, Qinghu -- Ferris, Patrick -- Lindquist, Erika -- Shapiro, Harris -- Lucas, Susan M -- Grimwood, Jane -- Schmutz, Jeremy -- Cardol, Pierre -- Cerutti, Heriberto -- Chanfreau, Guillaume -- Chen, Chun-Long -- Cognat, Valerie -- Croft, Martin T -- Dent, Rachel -- Dutcher, Susan -- Fernandez, Emilio -- Fukuzawa, Hideya -- Gonzalez-Ballester, David -- Gonzalez-Halphen, Diego -- Hallmann, Armin -- Hanikenne, Marc -- Hippler, Michael -- Inwood, William -- Jabbari, Kamel -- Kalanon, Ming -- Kuras, Richard -- Lefebvre, Paul A -- Lemaire, Stephane D -- Lobanov, Alexey V -- Lohr, Martin -- Manuell, Andrea -- Meier, Iris -- Mets, Laurens -- Mittag, Maria -- Mittelmeier, Telsa -- Moroney, James V -- Moseley, Jeffrey -- Napoli, Carolyn -- Nedelcu, Aurora M -- Niyogi, Krishna -- Novoselov, Sergey V -- Paulsen, Ian T -- Pazour, Greg -- Purton, Saul -- Ral, Jean-Philippe -- Riano-Pachon, Diego Mauricio -- Riekhof, Wayne -- Rymarquis, Linda -- Schroda, Michael -- Stern, David -- Umen, James -- Willows, Robert -- Wilson, Nedra -- Zimmer, Sara Lana -- Allmer, Jens -- Balk, Janneke -- Bisova, Katerina -- Chen, Chong-Jian -- Elias, Marek -- Gendler, Karla -- Hauser, Charles -- Lamb, Mary Rose -- Ledford, Heidi -- Long, Joanne C -- Minagawa, Jun -- Page, M Dudley -- Pan, Junmin -- Pootakham, Wirulda -- Roje, Sanja -- Rose, Annkatrin -- Stahlberg, Eric -- Terauchi, Aimee M -- Yang, Pinfen -- Ball, Steven -- Bowler, Chris -- Dieckmann, Carol L -- Gladyshev, Vadim N -- Green, Pamela -- Jorgensen, Richard -- Mayfield, Stephen -- Mueller-Roeber, Bernd -- Rajamani, Sathish -- Sayre, Richard T -- Brokstein, Peter -- Dubchak, Inna -- Goodstein, David -- Hornick, Leila -- Huang, Y Wayne -- Jhaveri, Jinal -- Luo, Yigong -- Martinez, Diego -- Ngau, Wing Chi Abby -- Otillar, Bobby -- Poliakov, Alexander -- Porter, Aaron -- Szajkowski, Lukasz -- Werner, Gregory -- Zhou, Kemin -- Grigoriev, Igor V -- Rokhsar, Daniel S -- Grossman, Arthur R -- GM07185/GM/NIGMS NIH HHS/ -- GM42143/GM/NIGMS NIH HHS/ -- R01 GM032843/GM/NIGMS NIH HHS/ -- R01 GM042143/GM/NIGMS NIH HHS/ -- R01 GM042143-09/GM/NIGMS NIH HHS/ -- R01 GM060992/GM/NIGMS NIH HHS/ -- R01 GM062915-06/GM/NIGMS NIH HHS/ -- R37 GM030626/GM/NIGMS NIH HHS/ -- R37 GM042143/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):245-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of California at Los Angeles, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17932292" target="_blank"〉PubMed〈/a〉

    The Selaginella genome identifies genetic changes associated with the evolution of vascular plants (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-05-10
    Description: Vascular plants appeared ~410 million years ago, then diverged into several lineages of which only two survive: the euphyllophytes (ferns and seed plants) and the lycophytes. We report here the genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported. By comparing gene content in evolutionarily diverse taxa, we found that the transition from a gametophyte- to a sporophyte-dominated life cycle required far fewer new genes than the transition from a nonseed vascular to a flowering plant, whereas secondary metabolic genes expanded extensively and in parallel in the lycophyte and angiosperm lineages. Selaginella differs in posttranscriptional gene regulation, including small RNA regulation of repetitive elements, an absence of the trans-acting small interfering RNA pathway, and extensive RNA editing of organellar genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3166216/" 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/PMC3166216/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banks, Jo Ann -- Nishiyama, Tomoaki -- Hasebe, Mitsuyasu -- Bowman, John L -- Gribskov, Michael -- dePamphilis, Claude -- Albert, Victor A -- Aono, Naoki -- Aoyama, Tsuyoshi -- Ambrose, Barbara A -- Ashton, Neil W -- Axtell, Michael J -- Barker, Elizabeth -- Barker, Michael S -- Bennetzen, Jeffrey L -- Bonawitz, Nicholas D -- Chapple, Clint -- Cheng, Chaoyang -- Correa, Luiz Gustavo Guedes -- Dacre, Michael -- DeBarry, Jeremy -- Dreyer, Ingo -- Elias, Marek -- Engstrom, Eric M -- Estelle, Mark -- Feng, Liang -- Finet, Cedric -- Floyd, Sandra K -- Frommer, Wolf B -- Fujita, Tomomichi -- Gramzow, Lydia -- Gutensohn, Michael -- Harholt, Jesper -- Hattori, Mitsuru -- Heyl, Alexander -- Hirai, Tadayoshi -- Hiwatashi, Yuji -- Ishikawa, Masaki -- Iwata, Mineko -- Karol, Kenneth G -- Koehler, Barbara -- Kolukisaoglu, Uener -- Kubo, Minoru -- Kurata, Tetsuya -- Lalonde, Sylvie -- Li, Kejie -- Li, Ying -- Litt, Amy -- Lyons, Eric -- Manning, Gerard -- Maruyama, Takeshi -- Michael, Todd P -- Mikami, Koji -- Miyazaki, Saori -- Morinaga, Shin-ichi -- Murata, Takashi -- Mueller-Roeber, Bernd -- Nelson, David R -- Obara, Mari -- Oguri, Yasuko -- Olmstead, Richard G -- Onodera, Naoko -- Petersen, Bent Larsen -- Pils, Birgit -- Prigge, Michael -- Rensing, Stefan A -- Riano-Pachon, Diego Mauricio -- Roberts, Alison W -- Sato, Yoshikatsu -- Scheller, Henrik Vibe -- Schulz, Burkhard -- Schulz, Christian -- Shakirov, Eugene V -- Shibagaki, Nakako -- Shinohara, Naoki -- Shippen, Dorothy E -- Sorensen, Iben -- Sotooka, Ryo -- Sugimoto, Nagisa -- Sugita, Mamoru -- Sumikawa, Naomi -- Tanurdzic, Milos -- Theissen, Gunter -- Ulvskov, Peter -- Wakazuki, Sachiko -- Weng, Jing-Ke -- Willats, William W G T -- Wipf, Daniel -- Wolf, Paul G -- Yang, Lixing -- Zimmer, Andreas D -- Zhu, Qihui -- Mitros, Therese -- Hellsten, Uffe -- Loque, Dominique -- Otillar, Robert -- Salamov, Asaf -- Schmutz, Jeremy -- Shapiro, Harris -- Lindquist, Erika -- Lucas, Susan -- Rokhsar, Daniel -- Grigoriev, Igor V -- GM065383/GM/NIGMS NIH HHS/ -- GM84051/GM/NIGMS NIH HHS/ -- HG004164/HG/NHGRI NIH HHS/ -- R01 GM043644/GM/NIGMS NIH HHS/ -- R01 GM084051/GM/NIGMS NIH HHS/ -- R01 GM084051-01A1/GM/NIGMS NIH HHS/ -- R01 HG004164/HG/NHGRI NIH HHS/ -- R01 HG004164-02/HG/NHGRI NIH HHS/ -- R01 HG004164-03/HG/NHGRI NIH HHS/ -- R01 HG004164-04/HG/NHGRI NIH HHS/ -- T32 GM007757/GM/NIGMS NIH HHS/ -- T32-HG00035/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2011 May 20;332(6032):960-3. doi: 10.1126/science.1203810.

    Description / Table of Contents: Aminomethylenephosphonic acids as corrosion inhibitors for aluminum pigments in aqueous mediaFlakelike aluminum pigments (aluminum content 〉99.5%) are corroded in aqueous alkaline mixtures of water and butyl glycol. Aminomethylenephosphonic acids inhibit this corrosion reaction. The temporal progress of the corrosion is determined by volumetric analysis of the evolved hydrogen. Direct comparison of aminomethylenephosphonic acids with analogous aminomethylenecarboxylic acids shows that the phosphonic acid group inhibits the corrosion significantly better than the carboxylic group. The actual corrosion inhibitors are in both cases (soluble) aluminum(III)-chelates, which are formed by a chemical reaction of the aminomethylenphosphonic resp.-carboxylic acids with the aluminum surface. This is proved by measuring the concentration of dissolved aluminum(III) in the corrosion medium with the help of atomic absorption spectroscopy and by using aluminum(III)chelates as corrosion inhibitors.
    Notes: Blättchenförmige Aluminiumpigmente (Aluminiumgehalt 〉99,5%) werden in alkalischen Gemischen aus Wasser und Butylglykol korrodiert. Durch Aminomethylenphosphonsäuren wird these Korrosionsreaktion inhibiert. Der zeitliche Verlauf der Korrosion wird durch gasvolumetrische; Bestimmung des entstehenden Wasserstoffs ermittelt. Der direkte Vergleich von Aminomethylenphosphonsäuren mit strukturanalogen Aminomethylencarbonsäuren ergibt, daß die Phosphonsäuregruppe deutlich besser korrosionsinhibierend wirkt als die Carbonsäuregruppe. In beiden Fällen sind die eigentlichen Korrosionsinhibitoren relativ leicht lösliche Aluminium(III)-Chelatkomplexe, die sich durch chemische Reaktion der Aminomethylenphosphon- bzw. -carbonsäuren mit der Aluminiumoberfläche bilden. Dies wird durch Messung der Konzentration von gelöstem Aluminium(III) im Korrosionsmedium durch Atomabsorptionsspektroskopie und durch den Einsatz von Aluminium(III)-Chelatkomplexen als Korrosionsinhibitoren nachgewiesen.

    Description / Table of Contents: Effect of pH on the corrosion inhibition of aluminium pigments by styrene-maleic acid copolymersAluminium pigments corrode in a mixture of water and butyl glycol in the ratio 9:1 with the evolution of hydrogen. The aluminium pigment without corrosion inhibitors reacts at pH 10 faster than at pH 8. Styrene-maleic acid copolymers inhibit this corrosion reaction; the corrosion inhibiting effect increases with decreasing acid number of the copolymers. With addition of low-molecular styrene-maleic acid copolymers (relative molar mass ≤ 60000) less hydrogen is evolved at pH 8 than at pH 10; the solubility of aluminium(III) in the corrosion medium is at pH 8 lower than at pH 10. With addition of high-molecular styrene-maleic acid copolymers (relative molar mass ≥ 100000) it is just the other way round: At pH 8 more hydrogen is evolved than at pH 10; the solubility of aluminium(III) in the corrosion medium is at pH 8 higher than at pH 10.
    Notes: Aluminiumpigmente korrodieren in einem Gemisch aus Wasser und Butylglykol im Verhältnis 9:1 unter Wasserstoffentwicklung. Dabei wird das Aluminiumpigment ohne inhibierende Zusätze bei pH 10 schneller als bei pH 8 umgesetzt. Styrol-Maleinsäure-Copolymere inhibieren diese Korrosionsreaktion, wobei deren korrosionsinhibierende Wirkung mit abnehmender Säurezahl steigt. Bei Zusatz von niedrigmolekularen Styrol-Maleinsäure-Copolymeren (Molmasse ≤ 60000) wird bei pH 8 weniger Wasserstoff entwickelt als bei pH 10; gleichzeitig ist die Löslichkeit von Aluminium(III) im Korrosionsmedium bei pH 8 kleiner als bei pH 10. Bei Zusatz von hochmolekularen Styrol-Maleinsäure-Copolymeren (Molmasse ≥ 100000) ist es genau umgekehrt: Bei pH 8 wird mehr Wasserstoff entwickelt als bei pH 10; dabei ist die Löslichkeit von Aluminium(III) bei pH 8 größer als bei pH 10.

    Description / Table of Contents: Corrosion inhibition of aluminium pigments by esters of gallic acidAluminium pigments corrode in mixtures of water and butyl glycol with the evolution of hydrogen, which can easily be measured gasvolumetrically. This corrosion reaction can be inhibited with addition of esters of gallic acid (gallates). The corrosion inhibiting effect of the gallates increases with increasing chain length of the ester alcohol; this connexion between the chemical structure of the inhibitors and the evolved volumes of hydrogen can be correlated mathematically with the help of an exponential function. The best inhibitor dodecyl gallate, which is an amphiphilic molecule with a chelating head group, showed protective values of about 99 %. To corroborate the assumption, that amphiphilic molecules with chelating head groups are in general effective inhibitors for the examined corrosion reaction, a second example, the amphiphilic agaric acid (α-hexadecyl citric acid) was tested in comparison to the head group (citric acid); again the amphiphilic molecule inhibited the corrosion reaction of aluminium pigment more effectively as the head group alone.
    Notes: Aluminiumpigmente korrodieren in Gemischen aus Wasser und Butylglykol bei pH 8 bzw. 10 unter Wasserstoffentwicklung, was gasvolumetrisch leicht gemessen werden kann. Diese Korrosionsreaktion kann durch Zusatz von Estern der Gallussäure (Gallate) inhibiert werden. Dabei steigt die korrosionsinhibierende Wirkung der Gallate mit zunehmender Kettenlänge des Esteralkohols; dieser Zusammenhang zwischen dem chemischen Aufbau der Inhibitoren und der entwickelten Menge an Wasserstoff läßt sich mit Hilfe einer Exponential funktion mathematisch korrelieren. Mit dem besten Inhibitor Dodecylgallat, das ein Amphiphil mit zur Chelatkomplexbildung befähigter Kopfgruppe ist, wurden Schutzwerte um 99% erreicht. Um die Vermutung, das derartige Amphiphile allgemein gute Inhibitoren für die untersuchte Korrosionsreaktion sind, zu erhärten, wurde als zweites Beispiel das Amphiphil Agaricinsäure (α-Hexadecylcitronensäure) im Vergleich zur Kopfgruppe Citronensäure geprüft; auch hier inhibierte das Amphiphil die Korrosionsreaktion des Aluminiumpigments besser als die Kopfgruppe alleine.

    Description / Table of Contents: Corrosion inhibition resp. stimulation of aluminium pigments in aqueous alkaline medium by polyacrylic acidsFlakelike aluminium pigments (aluminium content 〉 99.5%) are corroded in a mixture of water and butyl glycol at pH = 10 by the evolution of hydrogen. Low-molecular weight polyacrylic acids inhibit the corrosion of aluminium pigments with addition of 0.3-0.5 weight-% significantly better than high-molecular weight polyacrylic acids. By addition of very low amounts (0.05-0.1 weight-%) of polyacrylic acid the low-molecular ones show no effect whereas high-molecular polyacrylic acids stimulate the corrosion reaction. That means that high-molecular weight polyacrylic acids show a contrary action depending on their concentration. The measurement of dissolved aluminium(III) by atomic absorption spectroscopy indicates the formation of (at least partial) soluble aluminium(III)-polyacrylate-complexes whereby the solubility with addition of low-molecular weight polyacrylic acids is lower than with high-molecular.
    Notes: Blättchenförmige Aluminiumpigmente (Aluminiumgehalt 〉 99,5%) werden in einem Gemisch aus Wasser und Butylglykol bei pH = 10 schnell unter Wasserstoffentwicklung korrodiert. Niedrigmolekulare Polyacrylsäuren inhibieren bei einem Zusatz von 0,3-0,5 Gew.-% die Korrosion von Aluminiumpigmenten deutlich besser als hochmolekulare. Bei sehr niedrigen Zusatzmengen (0,05-0,1 Gew.-%) von Polyacrylsäuren zeigen die niedrigmolekularen keine Wirkung, während hochmolekulare die Korrosion stimulieren. D.h. hochmolekulare Polyacrylsäuren haben je nach Konzentration eine völlig gegensätzliche Wirkung. Die Messung von gelöstem Aluminium(III) im Korrosionsmedium durch Atomabsorptionsspektroskopie spricht für die Bildung von (zumindest teilweise) löslichen Aluminium(III)-Polyacrylat-Komplexen, wobei die Löslichkeit bei niedrigmolekularen Polyacrylsäuren niedriger ist als bei hochmolekularen.

    Description / Table of Contents: PH-dependency of the corrosion inhibiting resp. stimulating effect of polyacrylic acids on aluminium pigmentsThe isoelectric point (IEP: pH ≈ 9) of aluminium oxide is of significant influence for the corrosion inhibiting effect of polyacrylic acids with respect to aluminium pigments in alkaline aqueous medium:1Above the IEP (pH 10):High- and low-molecular weight polyacrylic acids inhibit the corrosion whereby their corrosion inhibiting effect decreases with increasing molecular weight.2Below the IEP (pH 8):Low-molecular weight polyacrylic acids inhibit the corrosion but less effective as at pH 10; the corrosion inhibiting effect decreases with increasing molecular weight.High-molecular weight polyacrylic acids stimulate the corrosion reaction; i.e., at the IEP a change of their effect takes place.
    Notes: Der isoelektrische Punkt (IEP: pH ≈ 9) von Aluminiumoxid ist von entscheidender Bedeutung für die korrosionsinhibierende Wirkung von Polyacrylsäuren in Bezug auf Aluminiumpigmente im alkalisch wäßrigen Medium:1Oberhalb des IEP (pH 10):Hoch- und niedrigmolekulare Polyacrylsäuren inhibieren die Korrosion, wobei deren Wirkung mit zunehmender Molmasse abnimmt.2Unterhalb des IEP (pH 8):Niedrigmolekulare Polyacrylsäuren inhibieren die Korrosion, aber weniger effektiv als bei pH 10; die korrosionsinhibierende Wirkung nimmt mit zunehmender Molmasse ab.Hochmolekulare Polyacrylsäuren stimulieren die Korrosion; d. h. am IEP findet eine Wirkungsumkehr statt.
