    Description: Fish have a complex self-defense mechanism against microbial invasion. Recently, l -lysine α-oxidases have been identified from a number of fish species as a novel type of antibacterial protein in the integument. These enzymes exhibit strict substrate specificity for l -lysine, but the underlying mechanisms and details of their catalytic properties remain unknown. In this study, a synthetic gene coding for Scomber japonicus l -lysine α-oxidase, originally termed AIP (for apoptosis-inducing protein), was expressed in Pichia pastoris , and the recombinant enzyme (rAIP) was purified and characterized. rAIP exhibited essentially the same substrate specificity as the native enzyme, catalyzing the oxidative deamination of l -lysine as an exclusive substrate. rAIP was N -glycosylated and remained active over a wide range of pH, with an optimal pH of 7.5. The enzyme was stable in the pH range from 4.5 to 10.0 and was thermally stable up to 60°C. A molecular modelling of rAIP and a comparative structure/sequence analysis with homologous enzymes indicate that Asp 220 and Asp 320 are the substrate-binding residues that are likely to confer exclusive substrate specificity for l -lysine on the fish enzymes.

    Description: We observed isosymmetric phase transitions of orthopyroxene in the Mg 2 Si 2 O 6 -Fe 2 Si 2 O 6 system during high-temperature in situ X-ray powder diffraction experiments with a multiple-detector system and a high-temperature strip heater chamber in an atmosphere of Ar plus 1% H 2 . The transition temperatures we determined for natural orthopyroxenes were 1113–1147, 1120–1139, and around 1200 °C for Fs 10 , Fs 14 , and Fs 37 , respectively, and those for synthetic orthopyroxenes were 1048–1075, 961–1048, and 1037–1148 °C for Fs 20 , Fs 30 , and Fs 46 , respectively. Our experiments showed that the transition from low- to high-temperature orthopyroxene in the Mg 2 Si 2 O 6 -Fe 2 Si 2 O 6 system occurred at about 1000–1200 °C. We concluded that the stability field of low-temperature orthopyroxene was below 1000 °C and that of high-temperature orthopyroxene was above 1200 °C.

    Description: Mice lacking mCry1 and mCry2 are behaviorally arrhythmic. As shown here, cyclic expression of the clock genes mPer1 and mPer2 (mammalian Period genes 1 and 2) in the suprachiasmatic nucleus and peripheral tissues is abolished and mPer1 and mPer2 mRNA levels are constitutively high. These findings indicate that the biological clock is eliminated in the absence of both mCRY1 and mCRY2 (mammalian cryptochromes 1 and 2) and support the idea that mammalian CRY proteins act in the negative limb of the circadian feedback loop. The mCry double-mutant mice retain the ability to have mPer1 and mPer2 expression induced by a brief light stimulus known to phase-shift the biological clock in wild-type animals. Thus, mCRY1 and mCRY2 are dispensable for light-induced phase shifting of the biological clock.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Okamura, H -- Miyake, S -- Sumi, Y -- Yamaguchi, S -- Yasui, A -- Muijtjens, M -- Hoeijmakers, J H -- van der Horst, G T -- New York, N.Y. -- Science. 1999 Dec 24;286(5449):2531-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Brain Science, Kobe University School of Medicine, Kobe 650-0017, Japan. okamurah@kobe-u.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10617474" target="_blank"〉PubMed〈/a〉

    Description: This study describes comprehensive polling of transcription start and termination sites and analysis of previously unidentified full-length complementary DNAs derived from the mouse genome. We identify the 5' and 3' boundaries of 181,047 transcripts with extensive variation in transcripts arising from alternative promoter usage, splicing, and polyadenylation. There are 16,247 new mouse protein-coding transcripts, including 5154 encoding previously unidentified proteins. Genomic mapping of the transcriptome reveals transcriptional forests, with overlapping transcription on both strands, separated by deserts in which few transcripts are observed. The data provide a comprehensive platform for the comparative analysis of mammalian transcriptional regulation in differentiation and development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carninci, P -- Kasukawa, T -- Katayama, S -- Gough, J -- Frith, M C -- Maeda, N -- Oyama, R -- Ravasi, T -- Lenhard, B -- Wells, C -- Kodzius, R -- Shimokawa, K -- Bajic, V B -- Brenner, S E -- Batalov, S -- Forrest, A R R -- Zavolan, M -- Davis, M J -- Wilming, L G -- Aidinis, V -- Allen, J E -- Ambesi-Impiombato, A -- Apweiler, R -- Aturaliya, R N -- Bailey, T L -- Bansal, M -- Baxter, L -- Beisel, K W -- Bersano, T -- Bono, H -- Chalk, A M -- Chiu, K P -- Choudhary, V -- Christoffels, A -- Clutterbuck, D R -- Crowe, M L -- Dalla, E -- Dalrymple, B P -- de Bono, B -- Della Gatta, G -- di Bernardo, D -- Down, T -- Engstrom, P -- Fagiolini, M -- Faulkner, G -- Fletcher, C F -- Fukushima, T -- Furuno, M -- Futaki, S -- Gariboldi, M -- Georgii-Hemming, P -- Gingeras, T R -- Gojobori, T -- Green, R E -- Gustincich, S -- Harbers, M -- Hayashi, Y -- Hensch, T K -- Hirokawa, N -- Hill, D -- Huminiecki, L -- Iacono, M -- Ikeo, K -- Iwama, A -- Ishikawa, T -- Jakt, M -- Kanapin, A -- Katoh, M -- Kawasawa, Y -- Kelso, J -- Kitamura, H -- Kitano, H -- Kollias, G -- Krishnan, S P T -- Kruger, A -- Kummerfeld, S K -- Kurochkin, I V -- Lareau, L F -- Lazarevic, D -- Lipovich, L -- Liu, J -- Liuni, S -- McWilliam, S -- Madan Babu, M -- Madera, M -- Marchionni, L -- Matsuda, H -- Matsuzawa, S -- Miki, H -- Mignone, F -- Miyake, S -- Morris, K -- Mottagui-Tabar, S -- Mulder, N -- Nakano, N -- Nakauchi, H -- Ng, P -- Nilsson, R -- Nishiguchi, S -- Nishikawa, S -- Nori, F -- Ohara, O -- Okazaki, Y -- Orlando, V -- Pang, K C -- Pavan, W J -- Pavesi, G -- Pesole, G -- Petrovsky, N -- Piazza, S -- Reed, J -- Reid, J F -- Ring, B Z -- Ringwald, M -- Rost, B -- Ruan, Y -- Salzberg, S L -- Sandelin, A -- Schneider, C -- Schonbach, C -- Sekiguchi, K -- Semple, C A M -- Seno, S -- Sessa, L -- Sheng, Y -- Shibata, Y -- Shimada, H -- Shimada, K -- Silva, D -- Sinclair, B -- Sperling, S -- Stupka, E -- Sugiura, K -- Sultana, R -- Takenaka, Y -- Taki, K -- Tammoja, K -- Tan, S L -- Tang, S -- Taylor, M S -- Tegner, J -- Teichmann, S A -- Ueda, H R -- van Nimwegen, E -- Verardo, R -- Wei, C L -- Yagi, K -- Yamanishi, H -- Zabarovsky, E -- Zhu, S -- Zimmer, A -- Hide, W -- Bult, C -- Grimmond, S M -- Teasdale, R D -- Liu, E T -- Brusic, V -- Quackenbush, J -- Wahlestedt, C -- Mattick, J S -- Hume, D A -- Kai, C -- Sasaki, D -- Tomaru, Y -- Fukuda, S -- Kanamori-Katayama, M -- Suzuki, M -- Aoki, J -- Arakawa, T -- Iida, J -- Imamura, K -- Itoh, M -- Kato, T -- Kawaji, H -- Kawagashira, N -- Kawashima, T -- Kojima, M -- Kondo, S -- Konno, H -- Nakano, K -- Ninomiya, N -- Nishio, T -- Okada, M -- Plessy, C -- Shibata, K -- Shiraki, T -- Suzuki, S -- Tagami, M -- Waki, K -- Watahiki, A -- Okamura-Oho, Y -- Suzuki, H -- Kawai, J -- Hayashizaki, Y -- FANTOM Consortium -- RIKEN Genome Exploration Research Group and Genome Science Group (Genome Network Project Core Group) -- TGM03P17/Telethon/Italy -- TGM06S01/Telethon/Italy -- New York, N.Y. -- Science. 2005 Sep 2;309(5740):1559-63.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16141072" target="_blank"〉PubMed〈/a〉

    Description: Weak solar activity and high cosmic-ray flux during the coming solar cycle are qualitatively anticipated by the recent observations that show the decline in the solar activity levels. We predict the cosmic-ray modulation and resultant radiation exposure at flight altitude by using the time-dependent and three dimensional model of the cosmic-ray modulation. Our galactic cosmic ray (GCR) model is based on the variations of the solar wind speed, the strength of the heliospheric magnetic field (HMF), and the tilt angle of the heliospheric current sheet. We reproduce the 22-year variation of the cosmic-ray modulation from 1980 to 2015 taking into account the gradient-curvature drift motion of GCRs. The energy spectra of GCR protons obtained by our model show good agreement with the observations by BESS and PAMELA except for a discrepancy at the solar maximum. Five year annual radiation dose around the solar minimum at the solar cycle 24/25 will be approximately 19 % higher than that in the last cycle. This is caused by the charge sign dependence of the cosmic-ray modulation, such as the flat-top profiles in a positive polarity.

    Description: The Red Sea has long been recognized as a region of high biodiversity and endemism. Despite this diversity and early history of scientific work, our understanding of the ecology of coral reefs in the Red Sea has lagged behind that of other large coral reef systems. We carried out a quantitative assessment of ISI-listed research published from the Red Sea in eight specific topics (apex predators, connectivity, coral bleaching, coral reproductive biology, herbivory, marine protected areas, non-coral invertebrates and reef associated bacteria) and compared the amount of research conducted in the Red Sea to that of the Australia’s Great Barrier Reef (GBR) and the Caribbean. On average, for these eight topics, the Red Sea had 1/6th the amount of research compared to the GBR and about 1/8th the amount of the Caribbean. Further, more than 50% of the published research from the Red Sea originated from the Gulf of Aqaba, a small area (〈 2% of the area of the Red Sea) in the far northern Red Sea. We summarize the general state of knowledge in these eight topics and highlight areas of future research priorities for the Red Sea region. Notably, data that could inform science-based management approaches is badly lacking in most Red Sea countries. The Red Sea, as a geologically “young” sea located in one of the warmest regions of the world, has the potential to provide insight to pressing topics such as speciation processes as well as the capacity of reef systems and organisms to adapt to global climate change. As one of the world’s most biodiverse coral reef regions, the Red Sea may yet have a significant role to play in our understanding of coral reef ecology at a global scale.

    Notes: Boron nitride films prepared by reactive ion plating from a boron evaporation source were characterized structurally using three independent electron optical techniques: energy filtered electron diffraction with radial distribution function analysis; electron energy-loss spectroscopy of the near-edge structure of the boron K edge; and spectroscopy of the plasmon region of the energy-loss spectrum. Both specimens had a graded BNx layer between the BN layer and the silicon substrate and in addition one specimen had a titanium bonding layer underneath the BNx layer. The presence of c-BN in both specimens was confirmed by all techniques. The specimen with the titanium bonding layer was examined in cross section and showed essentially pure c-BN on the surface. A model for the formation of c-BN assisted by the compressive stress generated during deposition is proposed.
