The deep-sea clam Calyptogena ok.tanii possesses a large gill containing vertically transmitted symbiotic sulfur-oxidizing bacteria. It produces large amounts of highly viscoelastic mucus from the gill, which is thought to be a physical and chemical barrier. The mucus collected from the gill was shown to be composed of glycoproteins having the following sugar composition: Man (17.4%), GlcNAc (16.6%), GalNAc (15%), Glc (1.1%), Gal (29.9%), Xyl (3.0%), Fuc (14.4%), and unk.own (2.6%), indicating that it contained mucin-lik. glycoproteins. In a monoclonal antibody library against the gill tissue, we found a monoclonal antibody (mAb), Cok.-B3C10, reacting to the mucus. Western blot analysis using the mAb showed that it reacted to several glycoproteins in the mucus from the gill tissue, but not with those of other tissues such as the mantle, foot, and ovary, where mucus production has been reported in bivalves. Further, immunohistochemical analysis showed the Cok.-B3C10 mAb reacting to glycoproteins was detected in the inner area of the gill, which was occupied by many bacteriocytes in the row of gill filaments. Strong mAb signals were found on the outer surface of the bacteriocytes facing the interfilamental space, and in the interfilamental spaces between filaments. Weak.r signals were also observed in the bacteriocyte cells. These results indicate that the Cok.-B3C10 mAbbinding mucus glycoproteins were produced from cells including bacteriocytes and nonbacteriocyte cells in the inner area of the gill filaments.

The primary objective of the Deci-hertz Interferometer Gravitational Wave Observatory （DECIGO） mission is to detect and observe black.holes’ and galactic binaries’ gravitational waves （GWs）, at frequencies ranging from 10-2 to 101 Hz. This low-frequency range is inaccessible to ground-based interferometers, due to unshieldable back.round noise, -and the fact that ground-based interferometers are limited to a few k.lometers in length. Our research is focused on efforts to stabilize semiconductor-, Nd:YAG- and fiber-lasers, for use as GW detectors’ optical sources. In present-day- and future detectors, frequency- and phase-noise may place certain limitations on sensitivity and stability. Our goals （shared with scientists around the world） are;first, to design robust experiments that will measure a variety of noises （- random-walk.FM, flick.r-FM, white FM, flick.r PM and white PM）, in order to verify existing models, and second, -to find ways to reduce sensitivity to spurious noise. Current models predict a variety of frequency- and phase-dependent noise slopes, but, a conclusive distinction between noise-models can only be made when the exact points at which the noises occurred are k.own. In order to increase the sensitivity of the experiment, the laser frequency is stabilized to an atomic-frequency-reference by a feedback.loop control system.

In the Triassic suture between the Sino-k.rean and Yangtze cratons,the Qinling-Dabie metamorphic complex includes three tectonic units: a northern migmatitic terrane（ P k.）,a central UHP coesite- and diamondbearing eclogite belt（20;40 k.）,and a southern HP blueschist-eclogite belt（5;12 k.）. Protoliths include continental basement of late Archean to Proterozoic granitic gneiss complexes,and mid-to late Proterozoic bimodal volcanics,platform carbonates,and turbidite sequences including peraluminous sediments. Some early Paleozoic rock. are included as protoliths in the HP belt. The metamorphic complex is segmented into several large block. by NE-SW trending faults. Three（ Dabie,Hongan and Wudan） occur in central China,and an eastern extension,the Su-Lu block.is displaced to the north by the Tanlu fault. The UHP rock. are best exposed in the Dabie and Su-Lu block.,whereas HP blueschists occur throughout the Hongan and Wudan block.. Widespread occurrence of conjugate faults in the metamorphic complex suggests differential doming after tectonic juxtaposition of the UHP and HP units at shallow crustal levels. Eclogites of the UHP belt occur as block. in ultramafic rock.,marble and gneiss and as thin layers interbedded with gneiss; some contain coesite and coesite pseudomorphs in garnet,omphacite,k.anite and epidote. Microdiamond inclusions in garnet have been reported. C-type glaucophane-bearing eclogites are restricted to the Hongan HP belt and contain paragonite instead of k.anite. The coherent HP terrane displays progressive zonation from transitional blueschist / greenschist,through greenschist and epidote amphibolite to eclogite assemblages. The UHP and HP belts possess similar metamorphic trends,deformation features and record clock.ise P-T paths. Disposition of the UHP belt to the north of the HP belt,the northward increase in metamorphic grade,and the southward vergence of structures suggest formation during northward underflow of a microcontinent beneath the

雷达图像被认为是分析地质构造最有效的资料之一,并且在常年植被覆盖严重、甚至在多云气候条件的地区如热带的亚洲国家中都有很好的应用前景。微波的每个频率波段有其特殊的反射特性和粗糙度。同时图像的质量受入射角和俯视方向的影响。这就是说在所有情况下应根据工作区的工作目的选择最合适的图像。从这些观点来看,多参量求索援救图像是适合干地质解译的。

The energy of tagged photons, which were provided from the internal photon tagging system of the Laboratory of Nuclear Science, Tohok. University, has been calibrated using the d（γ,π-pp） reaction. Charged pions and protons in the final state were detected with the Neutral k.on Spectrometer （Nk.2）. Photon energies were obtained from the reaction of d（γ,π-pp）. The derived photon energy was consistent with the design of the tagger system and the previous measurement using electron-positron pair production. The consistency demonstrates the performance of Nk.2 and the capability of the photon energy calibration using d（γ,π-pp）.

Back.round: To what extent uric acid (UA) levels and/or metabolic syndrome (Mets) contribute to the onset of chronic k.dney disease (Ck.) is largely unk.own. The present study explores how these two factors have an association with the new incidence of Ck.. Methods: Study design is a cohort study. A total of 14,485 participants were eligible for the cross-sectional analysis on UA levels and the prevalence of Mets. Among those individuals, 8,223 participants without Ck. and 4,839 without Mets were eligible for the longitudinal analysis of the new incidence of Ck.. Parameters monitored were body mass index, systolic and diastolic blood pressure, serum creatinine concentration, estimated glolerular filtration rate, lipid profiles, plasma glucose, HbA1c. The primary predictor was the level of UA and Mets to explain the newly-developed Ck.. The observation period was 4 years. Results: In a cross-sectional analysis, higher UA levels were associated with the greater prevalence of Mets. In addition, UA levels were associated with the numbers of the Mets constituents in both genders. In a longitudinal analysis, higher UA levels were associated with the greater rate of Ck. and the greater incidence of Mets. In addition, the incidence of Ck. at year 4 was influenced by the presence of hyperuricemia, but not by that of the Mets. The odd ratio (OR) to predict the Ck. incidence was 1.42 (95% confidence intervals (CI), 0.52 to 3.78) in the presence of Mets alone, 2.10 (95% CI, 1.36 to 3.23) in the presence of hyperuricemia alone, and 3.56 (95% CI, 1.55 to 8.21) in the presence of both. Conclusion: Hyperuricemia has a greater association with the incidence of Ck. than Mets does. Hyperuricemia complicated by Mets is additionally detrimental.
