    Description: Tribolium castaneum is a member of the most species-rich eukaryotic order, a powerful model organism for the study of generalized insect development, and an important pest of stored agricultural products. We describe its genome sequence here. This omnivorous beetle has evolved the ability to interact with a diverse chemical environment, as shown by large expansions in odorant and gustatory receptors, as well as P450 and other detoxification enzymes. Development in Tribolium is more representative of other insects than is Drosophila, a fact reflected in gene content and function. For example, Tribolium has retained more ancestral genes involved in cell-cell communication than Drosophila, some being expressed in the growth zone crucial for axial elongation in short-germ development. Systemic RNA interference in T. castaneum functions differently from that in Caenorhabditis elegans, but nevertheless offers similar power for the elucidation of gene function and identification of targets for selective insect control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tribolium Genome Sequencing Consortium -- Richards, Stephen -- Gibbs, Richard A -- Weinstock, George M -- Brown, Susan J -- Denell, Robin -- Beeman, Richard W -- Gibbs, Richard -- Bucher, Gregor -- Friedrich, Markus -- Grimmelikhuijzen, Cornelis J P -- Klingler, Martin -- Lorenzen, Marce -- Roth, Siegfried -- Schroder, Reinhard -- Tautz, Diethard -- Zdobnov, Evgeny M -- Muzny, Donna -- Attaway, Tony -- Bell, Stephanie -- Buhay, Christian J -- Chandrabose, Mimi N -- Chavez, Dean -- Clerk-Blankenburg, Kerstin P -- Cree, Andrew -- Dao, Marvin -- Davis, Clay -- Chacko, Joseph -- Dinh, Huyen -- Dugan-Rocha, Shannon -- Fowler, Gerald -- Garner, Toni T -- Garnes, Jeffrey -- Gnirke, Andreas -- Hawes, Alica -- Hernandez, Judith -- Hines, Sandra -- Holder, Michael -- Hume, Jennifer -- Jhangiani, Shalini N -- Joshi, Vandita -- Khan, Ziad Mohid -- Jackson, LaRonda -- Kovar, Christie -- Kowis, Andrea -- Lee, Sandra -- Lewis, Lora R -- Margolis, Jon -- Morgan, Margaret -- Nazareth, Lynne V -- Nguyen, Ngoc -- Okwuonu, Geoffrey -- Parker, David -- Ruiz, San-Juana -- Santibanez, Jireh -- Savard, Joel -- Scherer, Steven E -- Schneider, Brian -- Sodergren, Erica -- Vattahil, Selina -- Villasana, Donna -- White, Courtney S -- Wright, Rita -- Park, Yoonseong -- Lord, Jeff -- Oppert, Brenda -- Brown, Susan -- Wang, Liangjiang -- Weinstock, George -- Liu, Yue -- Worley, Kim -- Elsik, Christine G -- Reese, Justin T -- Elhaik, Eran -- Landan, Giddy -- Graur, Dan -- Arensburger, Peter -- Atkinson, Peter -- Beidler, Jim -- Demuth, Jeffery P -- Drury, Douglas W -- Du, Yu-Zhou -- Fujiwara, Haruhiko -- Maselli, Vincenza -- Osanai, Mizuko -- Robertson, Hugh M -- Tu, Zhijian -- Wang, Jian-jun -- Wang, Suzhi -- Song, Henry -- Zhang, Lan -- Werner, Doreen -- Stanke, Mario -- Morgenstern, Burkhard -- Solovyev, Victor -- Kosarev, Peter -- Brown, Garth -- Chen, Hsiu-Chuan -- Ermolaeva, Olga -- Hlavina, Wratko -- Kapustin, Yuri -- Kiryutin, Boris -- Kitts, Paul -- Maglott, Donna -- Pruitt, Kim -- Sapojnikov, Victor -- Souvorov, Alexandre -- Mackey, Aaron J -- Waterhouse, Robert M -- Wyder, Stefan -- Kriventseva, Evgenia V -- Kadowaki, Tatsuhiko -- Bork, Peer -- Aranda, Manuel -- Bao, Riyue -- Beermann, Anke -- Berns, Nicola -- Bolognesi, Renata -- Bonneton, Francois -- Bopp, Daniel -- Butts, Thomas -- Chaumot, Arnaud -- Denell, Robin E -- Ferrier, David E K -- Gordon, Cassondra M -- Jindra, Marek -- Lan, Que -- Lattorff, H Michael G -- Laudet, Vincent -- von Levetsow, Cornelia -- Liu, Zhenyi -- Lutz, Rebekka -- Lynch, Jeremy A -- da Fonseca, Rodrigo Nunes -- Posnien, Nico -- Reuter, Rolf -- Schinko, Johannes B -- Schmitt, Christian -- Schoppmeier, Michael -- Shippy, Teresa D -- Simonnet, Franck -- Marques-Souza, Henrique -- Tomoyasu, Yoshinori -- Trauner, Jochen -- Van der Zee, Maurijn -- Vervoort, Michel -- Wittkopp, Nadine -- Wimmer, Ernst A -- Yang, Xiaoyun -- Jones, Andrew K -- Sattelle, David B -- Ebert, Paul R -- Nelson, David -- Scott, Jeffrey G -- Muthukrishnan, Subbaratnam -- Kramer, Karl J -- Arakane, Yasuyuki -- Zhu, Qingsong -- Hogenkamp, David -- Dixit, Radhika -- Jiang, Haobo -- Zou, Zhen -- Marshall, Jeremy -- Elpidina, Elena -- Vinokurov, Konstantin -- Oppert, Cris -- Evans, Jay -- Lu, Zhiqiang -- Zhao, Picheng -- Sumathipala, Niranji -- Altincicek, Boran -- Vilcinskas, Andreas -- Williams, Michael -- Hultmark, Dan -- Hetru, Charles -- Hauser, Frank -- Cazzamali, Giuseppe -- Williamson, Michael -- Li, Bin -- Tanaka, Yoshiaki -- Predel, Reinhard -- Neupert, Susanne -- Schachtner, Joachim -- Verleyen, Peter -- Raible, Florian -- Walden, Kimberly K O -- Angeli, Sergio -- Foret, Sylvain -- Schuetz, Stefan -- Maleszka, Ryszard -- Miller, Sherry C -- Grossmann, Daniela -- BBS/B/12067/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/B/12067/2/Biotechnology and Biological Sciences Research Council/United Kingdom -- R01 GM058634/GM/NIGMS NIH HHS/ -- R01 HD029594/HD/NICHD NIH HHS/ -- R01 HD029594-16/HD/NICHD NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2008 Apr 24;452(7190):949-55. doi: 10.1038/nature06784.

    Description: Phosphine is a small redox-active gas that is used to protect global grain reserves, which are threatened by the emergence of phosphine resistance in pest insects. We find that polymorphisms responsible for genetic resistance cluster around the redox-active catalytic disulfide or the dimerization interface of dihydrolipoamide dehydrogenase (DLD) in insects (Rhyzopertha dominica and Tribolium castaneum) and nematodes (Caenorhabditis elegans). DLD is a core metabolic enzyme representing a new class of resistance factor for a redox-active metabolic toxin. It participates in four key steps of core metabolism, and metabolite profiles indicate that phosphine exposure in mutant and wild-type animals affects these steps differently. Mutation of DLD in C. elegans increases arsenite sensitivity. This specific vulnerability may be exploited to control phosphine-resistant insects and safeguard food security.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schlipalius, David I -- Valmas, Nicholas -- Tuck, Andrew G -- Jagadeesan, Rajeswaran -- Ma, Li -- Kaur, Ramandeep -- Goldinger, Anita -- Anderson, Cameron -- Kuang, Jujiao -- Zuryn, Steven -- Mau, Yosep S -- Cheng, Qiang -- Collins, Patrick J -- Nayak, Manoj K -- Schirra, Horst Joachim -- Hilliard, Massimo A -- Ebert, Paul R -- R01NS060129/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2012 Nov 9;338(6108):807-10. doi: 10.1126/science.1224951.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Agri-Science Queensland, Department of Agriculture, Fisheries and Forestry, Ecosciences Precinct, Brisbane, QLD 4001, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23139334" target="_blank"〉PubMed〈/a〉

    Description: We show that sex steroids protect the adult murine skeleton through a mechanism that is distinct from that used to preserve the mass and function of reproductive organs. The classical genotropic actions of sex steroid receptors are dispensable for their bone protective effects, but essential for their effects on reproductive tissues. A synthetic ligand (4-estren-3alpha,17beta-diol) that reproduces the nongenotropic effects of sex steroids, without affecting classical transcription, increases bone mass and strength in ovariectomized females above the level of the estrogen-replete state and is at least as effective as dihydrotestosterone in orchidectomized males, without affecting reproductive organs. Such ligands merit investigation as potential therapeutic alternatives to hormone replacement for osteoporosis in both women and men [corrected].〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kousteni, S -- Chen, J R -- Bellido, T -- Han, L -- Ali, A A -- O'Brien, C A -- Plotkin, L -- Fu, Q -- Mancino, A T -- Wen, Y -- Vertino, A M -- Powers, C C -- Stewart, S A -- Ebert, R -- Parfitt, A M -- Weinstein, R S -- Jilka, R L -- Manolagas, S C -- KO2-AR02127/AR/NIAMS NIH HHS/ -- P01-AG13918/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2002 Oct 25;298(5594):843-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Endocrinology and Metabolism, Department of Internal Medicine, and Center for Osteoporosis and Metabolic Bone Diseases, University of Arkansas for Medical Sciences, Little Rock, AR 72205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12399595" target="_blank"〉PubMed〈/a〉

    Description: Juno's Jupiter Energetic particle Detector Instrument (JEDI) often detects energetic electron beams over Jupiter's polar regions. In this paper, we document a subset of intense magnetic field-aligned beams of energetic electrons moving away from Jupiter at high magnetic latitudes both north and south of the planet. The number fluxes of these beams are often dominated by electrons with energies above about 1 MeV. These very narrow beams can create broad angular responses in JEDI with unique signatures in the detector count rates, probably because of 〉10 MeV electrons. We use these signatures to identify the most intense beams. These beams occur primarily above the swirl region of the polar cap aurora. This polar region is described as being of low brightness and high absorption and the most magnetically "open" at Jupiter.

    Notes: Abstract We report for the first time stimulated magneto-Raman scattering inp-type InSb. Two different Raman scattering processes were observed. The first one has a Raman shift of about 2cm−1/kG and is observed at magnetic fields up to 30kG. The other one is observable only at high magnetic fields above 30kG and shows Raman shifts between 1.2cm−1 and 3.0cm−1 with a tuning rate of about 0.2cm−1/kG. The first process can be interpreted either as spin-flip Raman scattering by photo-excited electrons in the conduction band or as Raman scattering by holes in the valence band involving transitions from heavy to light hole states. The other Raman shift observed seems to occur on account of transitions between the heavy hole ladders.

    Notes: Summary The absorbable deoxynojirimycin derivative emiglitate (BAY o 1248) is a potent competitive inhibitor of small intestinal α-glucosidases in man. In two similar randomized, placebo-controlled, double blind investigations, the efficacy, duration of action and tolerability of single doses of 10, 20 and 40 mg emiglitate have been assessed in healthy male volunteers after repeated sucrose or maize-starch loads at 08.00, 12.00 and 17.00 h. Even at the lowest dose used, emiglitate almost abolished the glycaemic (−88%) and hormonal responses after the first sucrose meal, simultaneously evoking significant hydrogen evolution (mean peak H2-concentration 〉100 ppm), which was not related to the dose, and which induced unacceptable symptoms of carbohydrate malabsorption, i.e. at the dosages tested, the inhibition of glycaemic and hormonal responses was at the expense of intolerable gastrointestinal adverse effects. Flattening of postprandial responses of blood glucose, serum insulin and gastric inhibitory polypeptide was still apparent after a second sucrose load 4 h later, demonstrating long-lasting inhibition of α-glucosidase activity. After starch, the dose dependency of inhibition emerged more clearly than after sucrose, i.e. the reduction was less pronounced. However, emiglitate led to significant reduction of the glycaemic and hormonal rises after both the first and second starch meals. Symptoms of carbohydrate malabsorption were absent after 10 mg and were negligible with 20 mg or 40 mg emiglitate. Breath hydrogen concentration increased gradually, indicating slight but significant carbohydrate malabsorption after the highest dose of the α-glucosidase inhibitor. The results show that a single morning dose of 20–40 mg emiglitate might be useful in the control of postprandial hyperglycaemia after breakfast and lunch. This dose of the inhibitor was effective after either both 50 g starch or 50 g sucrose as the substrate, but was only tolerable after the starch meal.
