    We report a measurement of the branching fraction Br(Bs -> Ds(*) Ds(*)) using a data sample corresponding to 1.3 fb^{-1} of integrated luminosity collected by the D0 experiment in 2002-2006 during Run II of the Fermilab Tevatron Collider. One Ds(*) meson was partially reconstructed in the decay Ds -> phi mu nu, and the other Ds(*) meson was identified using the decay Ds -> phi pi where no attempt was made to distinguish Ds and Ds* states. The resulting measurement is Br(Bs -> Ds(*) Ds(*)) = 0.039 +0.019 -0.017 (stat) +0.016 -0.015 (syst). This was subsequently used to estimate the width difference Delta Gamma^{CP}_s in the Bs-Bsbar system: Delta Gamma^{CP}_s / Gamma_s = 0.079 +0.038 -0.035 (stat) +0.031 -0.030 (syst).

    The decays Bs0→Ds(*)+Ds(*)- are reconstructed in a data sample corresponding to an integrated luminosity of 6.8  fb-1 collected by the CDF II detector at the Tevatron pp[over ¯] collider. All decay modes are observed with a significance of more than 10σ, and we measure the Bs0 production rate times Bs0→Ds(*)+Ds(*)- branching ratios relative to the normalization mode B0→Ds+D-to be 0.183±0.021±0.017 for Bs0→Ds+Ds-, 0.424±0.046±0.035 for Bs0→Ds*±Ds^∓, 0.654±0.072±0.065 for Bs0→Ds*+Ds*-, and 1.261±0.095±0.112 for the inclusive decay Bs0→Ds(*)+Ds(*)-, where the uncertainties are statistical and systematic. These results are the most precise single measurements to date and provide important constraints for indirect searches for nonstandard model physics in Bs0 mixing.

  10. Extending and Customising DS9

    Science.gov (United States)

    Clarke, D.; Allen, S. L.; Joye, W. A.

    2005-12-01

    UCO/Lick Observatory adopted SAOImage DS9 as the standard real-time and quick-look display for DEIMOS (commissioned Summer 2002) and subsequent instruments. Lick software staff made several modifications and extensions to DS9, taking advantage of its open architecture and the ease of adding Tcl/Tk code to the DS9 core at runtime. We worked in close collaboration with DS9 author Bill Joye on both core modifications and external `plug-ins'. Our poster describes features added to DS9 (in the core or externally), and a strategy for integrating DS9 with real-time image acquisition. The Lick software team invites other DS9 users to form a community and discuss code-sharing, APIs and other DS9 issues.

  11. Observation of the DsJ(2317) and DsJ(2457) in B decays

    Krokovny, P.

    2003-01-01

    We report the first observation of the B --> Dbar DsJ(2317) and B --> Dbar DsJ(2457) decays based on 123.8 10^6 BBar events collected with the Belle detector at KEKB. We observe the DsJ(2317) decay to Ds pi0 and DsJ(2457) decay to the Ds* pi0 and Ds gamma final states. We also set 90% CL upper limits for the decays DsJ(2317) --> Ds* gamma, DsJ(2457) --> Ds* gamma, DsJ(2457) --> Ds pi0 and DsJ(2457) --> Ds pi+ pi-.

    We report on searches for B- --> Ds- Phi and B- --> Ds*- Phi. In the context of the Standard Model, the branching fractions for these decays are expected to be highly suppressed, since they proceed through annhilation of the b and u-bar quarks in the B- meson. Our results are based on 234 million Upsilon(4S) --> B Bbar decays collected with the BaBar detector at SLAC. We find no evidence for these decays, and we set 90% confidence level upper limits on the branching fractions BF(B- --> Ds- Phi) Ds*- Phi) < 1.1x10^(-5). These results are consistent with Standard Model expectations.

    We report on a study of the B --> D DsJ(2317) and B --> D DsJ(2460) decays based on 123.7 x 10^6 BBar events collected with the Belle detector at KEKB. The B --> D DsJ(2317) and B --> D DsJ(2460) decays have been observed for the first time. We observe the DsJ(2317) decay to Ds pi0 and DsJ(2460) decay to the Ds* pi0 and Ds gamma final states. We also set the 90% CL upper limits for the decays DsJ(2317) --> Ds* gamma, DsJ(2460) --> Ds* gamma, DsJ(2460) --> Ds pi0 and DsJ(2460) --> Ds pi+ pi-.

    Using data collected near the Ds*+ Ds- peak production energy Ecm=4170 MeV by the CLEO-c detector, we search for Ds+ exclusive hadronic decays involving omega. We find B(Ds+ -> pi+ omega) = (0.21 +- 0.09 +- 0.01)%, B(Ds+ -> pi+ pi0 omega) = (2.78 +- 0.65 +- 0.25)%, B(Ds+ -> pi+ pi+ pi- omega) = (1.58 +- 0.45 +- 0.09)%, B(Ds+ -> pi+ eta omega) = (0.85 +- 0.54 +- 0.06)%, B(Ds+ -> K+ omega) K+ pi0 omega) K+ pi+ pi- omega) K+ eta omega)

  18. [Immunomodulatory drugs (IMiDs)].

    2014-06-01

    Immunomodulatory drugs (IMiDs) are a new class of anti-inflammatory and antineoplastic agents that have structural and functional similarities with their prototype compound, thalidomide. Although thalidomide and its derivatives, lenalidomide and pomalidomide, are widely used as an essential component in the treatment of selected hematologic neoplasms including multiple myeloma, the precise mechanisms by which these agents exert anti-tumor effects have yet to be clarified. Recently, a component of E3 ubiquitin ligase complex, cereblon (CRBN), has been identified as a direct molecular target for anti-neoplastic activities of IMiDs. CRBN has also been shown to be involved in IMiDs-mediated T-cell co-stimulation and cytokine production. Further studies are necessary to elucidate the CRBN-related molecular pathways that are essential for antitumor and immunomodulatory activities of IMiDs.

    We report a search for the decays $B^{0} \\to D_{s}^{-} D_{s}^{+}$, $B^{0} \\to D_{s}^{*-} D_{s}^{+}$, $B^{0} \\to D_{s}^{*-} D_{s}^{*+}$ in a sample of 232 million $\\Upsilon(4S)$ decays to \\BBb ~pairs collected with the \\babar detector at the PEP-II asymmetric-energy $e^+ e^-$ storage ring. We find no significant signal and set upper bounds for the branching fractions: ${\\cal B}(B^{0} \\to D_{s}^{-} D_{s}^{+}) < 1.0 \\times 10^{-4}, {\\cal B}(B^{0} \\to D_{s}^{*-} D_{s}^{+}) < 1.3 \\times 10^{-4}$ and ${\\cal B}(B^{0} \\to D_{s}^{*-} D_{s}^{*+}) < 2.4 \\times 10^{-4}$ at 90% confidence level.

    We have made a precise measurement of the absolute branching fractions of Bs->Ds(*)+ Ds(*)- decays using 121.4 fb-1 of data recorded by the Belle experiment running on the Upsilon(5S) resonance. The results are B(Bs0->Ds+ Ds-) = (0.58 +0.11 -0.09 +-0.13)%, B(Bs0->Ds*+- Ds-+) = (1.8 +-0.2 +-0.4)%, and B(Bs0->Ds*+ Ds*-) = (2.0 +-0.3 +-0.5)%; the sum is B(Bs0->Ds(*)+ Ds(*)- = (4.3 +-0.4 +-1.0)%. Assuming Bs->Ds(*)+ Ds(*)- saturates decays to CP-even final states, the branching fraction constrains the ratio Delta(Gamma_s)/cos(phi_s), where Delta(Gamma_s) is the difference in widths between the two Bs0-Bs0bar mass eigenstates, and phi_s is the CP-violating phase in Bs0-Bs0bar mixing. For phi_s=0 we obtain Delta(Gamma_s)/Gamma_s = 0.090 +-0.009 (stat.) +-0.023 (syst.), where Gamma_s is the mean decay width. We also measure for the first time the longitudinal polarization fraction of Bs->Ds*+ Ds*-; the result is 0.12 +0.30 -0.28 +0.04 -0.05.

    The purely leptonic decays Ds-->τν and Ds-->μν are studied in a sample of four million hadronic /Z decays collected with the ALEPH detector at the LEP e+e- collider from 1991 to 1995. The branching fractions are extracted from a combination of two analyses, one optimized to select Ds-->τν decays with /τ-->eνν¯ or /μνν¯, and the other optimized for Ds-->μν decays. The results are used to evaluate the Ds decay constant, within the Standard Model: fDs=[285+/-19(stat)+/-40(syst)] MeV.

    We report the observation of the exclusive decay Bs0-->Ds-Ds+ at the 7.5 standard deviation level using 355 pb(-1) of data collected by the CDF II detector in pp collisions at sqrt[s]=1.96 TeV at the Fermilab Tevatron. We measure the relative branching ratio B(Bs0-->Ds-Ds+)/B(B0-->D-Ds+)=1.44(-0.44)(+0.48). Using the world average value for B(B0-->D-Ds+), we find B(Bs0-->Ds-Ds+)=(9.4(-4.2)(+4.4))x10(-3). This provides a lower bound DeltaGammasCP/Gammas>or=2B(Bs0-->Ds-Ds+)>1.2x10(-2) at 95% C.L.

    We present preliminary results for the branching fraction B(Ds -> munu) using a 548 fb^-1 data sample collected by the Belle experiment at the KEKB e+e- collider. The Ds momentum is determined by full reconstruction of the recoil system in events of the type e+e- -> D*sDKX, D*s -> Ds gamma where X is any number of additional pions or photons from fragmentation. The full reconstruction method provides high resolution in the neutrino momentum and thus good background separation, equivalent to that reached at experiments at the tau-charm factories such as CLEO-c or BES. We obtain the preliminary branching fraction B(Ds -> munu) = (6.44 +- 0.76 (stat) +- 0.52 (syst)) x 10^(-3), implying a Ds decay constant of f_Ds = 275 +- 16 (stat) +- 12 (syst) MeV.

    We report a study of DsJ*(2317)+ and DsJ(2460)+ meson production in B decays. We observe the decays B+ -> DsJ(*)+ Dbar(*)0 and B0 -> DsJ(*)+ D(*)- with the subsequent decays DsJ*(2317)+ -> Ds+ pi0, DsJ(2460)+ -> Ds+ gamma, and DsJ(2460)+ -> Ds*+ pi0. Based on a data sample of 122.1 million BBbar pairs collected with the BaBar detector at the PEP-II B factory, we obtain branching fractions for these modes, including the previously unseen decays B -> DsJ(*)+ D*. In addition, we perform an angul...

    We report a study of DsJ*(2317)+ and DsJ(2460)+ meson production in B decays. We observe the decays B+ -> DsJ(*)+ Dbar(*)0 and B0 -> DsJ(*)+ D(*)- with the subsequent decays DsJ*(2317)+ -> Ds+ pi0, DsJ(2460)+ -> Ds+ gamma, and DsJ(2460)+ -> Ds*+ pi0. Based on a data sample of 122.1 million BBbar pairs collected with the BaBar detector at the PEP-II B factory, we obtain branching fractions for these modes, including the previously unseen decays B -> DsJ(*)+ D*. In addition, we perform an angular analysis of DsJ(2460)+ -> Ds+ gamma decays to test the different DsJ(2460)+ spin hypotheses.

    We examine e+e- to Ds- Ds*+ or Ds-* Ds+ collisions at 4170 MeV using the CLEO-c detector in order to measure the decay constant f_Ds+. We use the Ds+ to ell+ nu channel, where the ell+ designates either a mu+ or a tau+. Analyzing both modes simultaneously, we determine B(D_s^+ to mu+ nu)= (0.657 +- 0.090 +- 0.028)%, B(D_s^+ to tau+ nu)= (7.1 +- 1.4 +- 0.3)%, and extract f_Ds+ = 282 +- 16 +- 7 MeV. Combining with our previous determination of B(D+ to mu+ nu), we find that the ratio f_Ds+/f_D+ = 1.27 +- 0.12 +- 0.03. (All new results here are preliminary.) We compare with current theoretical estimates.

    The first measurement of the effective lifetime of the B(s)(0) meson in the decay B(s)(0) → Ds-Ds+ is reported using a proton-proton collision data set, corresponding to an integrated luminosity of 3 fb(-1), collected by the LHCb experiment. The measured value of the B(s)(0) → Ds-Ds+ effective lifetime is 1.379 ± 0.026 ± 0.017 ps, where the uncertainties are statistical and systematic, respectively. This lifetime translates into a measurement of the decay width of the light B(s)(0) mass eigenstate of ΓL = 0.725 ± 0.014 ± 0.009 ps(-1). The B(s)(0) lifetime is also measured using the flavor-specific B(s)(0)→ D-Ds+ decay to be 1.52 ± 0.15 ± 0.01 ps.

  18. Transpositional behaviour of the Ds element in the Ac/Ds system in rice

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Insertional mutagenesis based on maize Activator/Dissociator (Ac/Ds) transposons is becoming a major approach used to produce a saturated mutant collection in rice. In this research, Ds-T-DNA transformed homozygotes were crossed with Ac-T-DNA transformed homozygotes in order to establish an Ac/Ds transposon system in rice. The successive investigation of Ds transposition from F1 to F5 generations indicated that the frequencies of germinal transposition increased over successive generations and reached 54.2% in F3 generation. The Ds transposition pattern revealed that a Ds transposition induced an approximately 170-bp deletion of T-DNA sequence and another Ds transposition carried a 272-bp T-DNA sequence. Using thermal asymmetric interlaced PCR (TAIL-PCR), some flanking sequences of the Ds element were amplified. Analyses of 17 Ds-flanking sequences showed that five Ds were inserted into gene regions. The Ds could transpose not only to the linked sites but also to the unlinked sites. The frequency of inter-chromosomal transposition of Ds was 33.3%.

    The production rates of the orbitally excited Ds** mesons, Ds1 and Ds2*, are measured with the 4.1 million hadronic Z decays recorded by the ALEPH detector during 1991--1995. The Ds** mesons are reconstructed in the decay modes Ds1+ -> D*+ K0, Ds1+ -> D*0 K+ and Ds2*+ -> D0 K+. The production rate of the Ds1 is measured to be n(Z->Ds1+-)=(0.52+-0.09+-0.06)%, under the assumption that the two considered decay modes of the Ds1 saturate the branching ratio. The production rate of the Ds2* is determined to be n(Z->Ds2*+-)=(0.83+-0.29+0.07-0.13)%, assuming that the branching fraction of the decay Ds2*+ -> D0 K+ is 45%. The production rates in Z->cc and Z->bbar decays are measured separately.

    The Ds+- -> K+-K-+pi+- absolute branching fraction is measured using e+e- -> Ds*+- Ds1-+(2536) events collected by the Belle detector at the KEKB e+e- asymmetric energy collider. Using the ratio of yields when either the Ds1 or Ds* is fully reconstructed, we find Br(Ds+- -> K+-K-+pi+-)= (4.0+-0.4(stat)+-0.4(sys))%.

    In January of 1999 the NM DS-2 Mars microprobe will be launched to impact on Mars in December. The technical objectives of the missions are to demonstrate: key technologies, a passive atmospheric entry, highly integrated microelectronics which can withstand both low temperatures and high decelerations, and the capability to conduct in-situ, surface and subsurface science data acquisition. The scientific objectives are to determine if ice is present below the Martian surface, measure the local atmospheric pressure, characterize the thermal properties of the martian subsurface soil, and to estimate the vertical temperature gradient of the Martian soil. The battery requirements are 2-4 cell batteries, with voltage of 6-14 volts, capacity of 550 mAh at 80C, and 2Ah at 25C, shelf life of 2.5 years, an operating temperature of 60C and below, and the ability to withstand shock impact of 80,000 g's. The technical challenges and the approach is reviewed. The Li-SOCL2 system is reviewed, and graphs showing the current and voltage is displayed, along with the voltage over discharge time. The problems encountered during the testing were: (1) impact sensitivity, (2) cracking of the seals, and (3) delay in voltage. A new design resulted in no problems in the impact testing phase. The corrective actions for the seal problems involved: (1) pre weld fill tube, (2) an improved heat sink during case to cover weld and (3) change the seal dimensions to reduce stress. To correct the voltage delay problem the solutions involved: (1) drying the electrodes to reduce contamination by water, (2) assemblage of the cells within a week of electrode manufacture, (3) ensure electrolyte purity, and (4) provide second depassivation pulse after landing. The conclusions on further testing were that the battery can: (1) withstand anticipated shock of up to 80,000 g, (2) meet the discharge profile post shock at Mars temperatures, (3) meet the required self discharge rate and (4) meet environmental

    Using 586 $\\textrm{pb}^{-1}$ of $e^{+}e^{-}$ collision data acquired at $\\sqrt{s}=4.170$ GeV with the CLEO-c detector at the Cornell Electron Storage Ring, we report the first observation of $D_{s}^{*+} \\to D_{s}^{+} e^{+} e^{-}$ with a significance of $5.3 \\sigma$. The ratio of branching fractions $\\calB(D_{s}^{*+} \\to D_{s}^{+} e^{+} e^{-}) / \\calB(D_{s}^{*+} \\to D_{s}^{+} \\gamma)$ is measured to be $[ 0.72^{+0.15}_{-0.13} (\\textrm{stat}) \\pm 0.10 (\\textrm{syst})]%$, which is consistent with theoretical expectations.

    A combined mass and particle identification fit is used to make the first observation of the decay Bs --> Ds K and measure the branching fraction of Bs --> Ds K relative to Bs --> Ds pi. This analysis uses 1.2 fb^-1 integrated luminosity of pbar-p collisions at sqrt(s) = 1.96 TeV collected with the CDF II detector at the Fermilab Tevatron collider. We observe a Bs --> Ds K signal with a statistical significance of 8.1 sigma and measure Br(Bs --> Ds K)/Br(Bs --> Ds pi) = 0.097 +- 0.018(stat) +- 0.009(sys).

    Several aspects of transposition of an in vitro modified Ds element are described. This Ds element, designated Ds-r, is equipped with bacterial plasmid sequences and can, therefore, be rescued from the plant genome. Our results indicate that the Ds-r element has a 'late' timing of transposition from

    We study the positive parity charmed strange mesons using lattice QCD, the only reliable ab initio method to study QCD at low energies. Especially the experimentally observed $D_{s0}^*(2317)$ and $D_{s1}(2460)$ have challenged theory for quite some time. The dynamical lattice QCD simulations are performed at two distinct pion masses, $m_{\\pi}$ = 266 MeV and 156 MeV, using both $\\bar{c}s$ as well as $DK$ and $D^*K$ scattering operators in the construction of the correlation matrix in order to take into the account threshold effects. While the $J^P = 0^+$ channel benefited most from the inclusion of scattering operators, it was also crucial for the case of the $D_{s1}(2460)$. Using the L\\"uscher method, which relates the finite volume spectrum to the infinite volume scattering matrix, we were able to determine the near threshold behavior of the scattering amplitude. From it we extracted the binding momenta and the masses of the below-threshold bound states $D_{s0}^*(2317)$ and $D_{s1}(2460)$ by determining the pole positions of the scattering amplitudes. Our results compare well with experiment, resolving a long standing discrepancy between theory and experiment.

    We report the observation of the exclusive decay Bs0→Ds-Ds+ at the 7.5 standard deviation level using 355pb-1 of data collected by the CDF II detector in pp¯ collisions at s=1.96TeV at the Fermilab Tevatron. We measure the relative branching ratio B(Bs0→Ds-Ds+)/B(B0→D-Ds+)=1.44-0.44+0.48. Using the world average value for B(B0→D-Ds+), we find B(Bs0→Ds-Ds+)=(9.4-4.2+4.4)×10-3. This provides a lower bound ΔΓsCP/Γs≥2B(Bs0→Ds-Ds+)>1.2×10-2 at 95% C.L.

  2. Molecular components in D*s0(2317 and Ds1(2460 mesons

    Directory of Open Access Journals (Sweden)

    Ortega Pablo G.

    2016-01-01

    Full Text Available Different experiments have confirmed that the D*s0(2317 and Ds1(2460 mesons are very narrow states located, respectively, below the DK and D*K thresholds. This is markedly in contrast with the expectations of naive quark models and heavy quark symmetry. We address the mass shifts of the cs̄ ground states with quantum numbers JP = 0+ (D*s0(2317 and JP = 1+ (Ds1(2460 using a nonrelativistic constituent quark model in which quark-antiquark and meson-meson degrees of freedom are incorporated. The quark model has been applied to a wide range of hadronic observables and thus the model parameters are completely constrained. We observe that the coupling of the 0+ (1+ meson sector to the DK (D*K threshold is a key feature in lowering the masses of the corresponding D*s0(2317 and Ds1(2460 states predicted by the naive quark model, but also in describing the Ds1(2536 meson as the 1+ state of the jPq = 3/2+ doublet predicted by heavy quark symmetry and thus reproducing its strong decay properties. Two features of our formalism cannot be address nowadays by other approaches: the coupling of the D-wave D*K threshold in the JP = 1+ cs̄ channel and the computation of the probabilities associated with different Fock components in the physical state.

    The purely leptonic decays Ds -> tau nu and Ds -> mu nu are studied in a sample of four million hadronic Z decays collected with the ALEPH detector at the LEP e+e- collider from 1991 to 1995. The branching fractions are extracted from a combination of two analyses, one optimized to select Ds -> tau nu decays with tau -> e nu nubar or mu nu nubar, and the other optimized for Ds-> mu nu decays. The results are used to evaluate the Ds decay constant, within the Standard Model: fDs = [285 +- 19(stat) +- 40 (syst)] MeV.

    The nonautonomous maize Ds transposons can only move in the presence of the autonomous element Ac. They comprise a heterogeneous group that share 11-bp terminal inverted repeats (TIRs) and some subterminal repeats, but vary greatly in size and composition. Three classes of Ds elements can cause mutations: Ds-del, internal deletions of the 4.6-kb Ac element; Ds1, ~400-bp in size and sharing little homology with Ac, and Ds2, variably-sized elements containing about 0.5 kb from the Ac termini and unrelated internal sequences. Here, we analyze the entire complement of Ds-related sequences in the genome of the inbred B73 and ask whether additional classes of Ds-like (Ds-l) elements, not uncovered genetically, are mobilized by Ac. We also compare the makeup of Ds-related sequences in two maize inbreds of different origin. We found 903 elements with 11-bp Ac/Ds TIRs flanked by 8-bp target site duplications. Three resemble Ac, but carry small rearrangements. The others are much shorter, once extraneous insertions are removed. There are 331 Ds1 and 39 Ds2 elements, many of which are likely mobilized by Ac, and two novel classes of Ds-l elements. Ds-l3 elements lack subterminal homology with Ac, but carry transposase gene fragments, and represent decaying Ac elements. There are 44 such elements in B73. Ds-l4 elements share little similarity with Ac outside of the 11-bp TIR, have a modal length of ~1 kb, and carry filler DNA which, in a few cases, could be matched to gene fragments. Most Ds-related elements in B73 (486/903) fall in this class. None of the Ds-l elements tested responded to Ac. Only half of Ds insertion sites examined are shared between the inbreds B73 and W22. The majority of Ds-related sequences in maize correspond to Ds-l elements that do not transpose in the presence of Ac. Unlike actively transposing elements, many Ds-l elements are inserted in repetitive DNA, where they probably become methylated and begin to decay. The filler DNA present in most elements

    In this paper, a comprising survey on the thermal and elastic behaviour of 20 high-temperature alloys is given. Besides Ni base forge and cast alloys (especially IN 738 LC and CMSX 6), the measurements were carried out in vacuum maximally up to 1300deg C with directionally solidified and monocrystalline superalloys as well as with cobalt base, iron base and Ni-Fe-Cr alloys. The creep strain at increased temperatures and the hot-isostatic re-compaction were also considered in the investigations. Dynamic and static measurement methods as for example the resonance method, the ultrasonic pulse transit-time measurement as well as the four-point bending tests and compression tests were used for the determination of the elastic properties. The determination of the expansion behaviour was carried out dilatometrically. It can be concluded from this study that the elastic anisotropy influences considerably the mechanical and thermal properties of the materials investigated. (orig./MM).

    This work consists of two parts. The first part reports on the measurement of the elastic properties and the thermal expansion coefficients of selected, technically important high temperature alloys (as e.g. cast alloys and forged alloys, directionally solidified alloys, single crystals) in the temperature range of 20deg C to 1200deg C. The orientation dependence and the structure dependence of these characteristics are of special interest especially in this study. The second part reports on investigations of selected materials with regard to the quantitative relationships between the elastic properties of single-phase single crystals and multiphase single crystals, directionally solidified alloys as well as polycrystals without und with texture, in the temperature range of 20deg C to 1200deg C. The limiting value concept and the phase mixing rules are used for the evaluation. (orig./MM) With 133 figs., 18 tabs., 322 refs.

  8. Multichannel calculation for Ds* vector states and the Ds(2632) resonance

    We study bound states below threshold and resonances above threshold in the D0-K+ and Ds-eta systems, using a many-coupled-channel model for non-exotic meson-meson scattering applied to states with the quantum numbers of c-sbar quark-antiquark vector mesons. We fit the ground state at 2.112 GeV, whence the lowest resonances in D0-K+ come out at 2.43, 2.61, 2.73, 3.06, and 3.11 GeV. The resonance at 2.61 GeV acquires a width of about 3 MeV, while its partial P-wave cross section is up to six times larger in Ds-eta than in D0-K+, provided a mechanism accounting for Okubo-Zweig-Iizuka--forbidden decays is included. The latter finding is in agreement with the observations of the SELEX collaboration with respect to the recently reported Ds(2632) resonance. Therefore, we conclude that the Ds(2632) is most probably the first radial excitation of the Ds*(2112) meson.

    We estimate the partial widths for the radiative and pionic transitions from the $D_{s1}(2460)$ to the $D_{s0}(2317)$ in a molecule scenario, in which the $D_{s1}(2460)$ and $D_{s0}^\\ast(2317)$ are considered as hadronic molecule states of $DK$ and $D^\\ast K$, respectively. The partial widths for the $D_{s1}(2460) \\to D_{s0}^\\ast(2317) \\pi^0$ and $D_{s1}(2460) \\to D_{s0}^\\ast(2317) \\gamma$ are evaluated to be about $0.19 \\sim 0.22$ keV and $3.0 \\sim 3.1$ keV, respectively. In addition, the ratio of the $D_{s1}(2460) \\to D_{s0}(2317) \\gamma$ and $D_{s1}(2460) \\to D_{s}^\\ast \\pi^0$ is estimated to be about $(6.6\\sim 10.6) \\times 10^{-2}$, which is safely under the measured upper limit.

    Full Text Available We study Ds+ decays to final states involving the η′ with a 482 pb−1 data sample collected at s=4.009 GeV with the BESIII detector at the BEPCII collider. We measure the branching fractions B(Ds+→η′X=(8.8±1.8±0.5% and B(Ds+→η′ρ+=(5.8±1.4±0.4% where the first uncertainty is statistical and the second is systematic. In addition, we estimate an upper limit on the non-resonant branching ratio B(Ds+→η′π+π0<5.1% at the 90% confidence level. Our results are consistent with CLEO's recent measurements and help to resolve the disagreement between the theoretical prediction and CLEO's previous measurement of B(Ds+→η′ρ+.

    We present measurements of absolute branching fractions of hadronic and leptonic Ds+ decays to K- K+ pi+, anti-K0 K+, eta pi+, mu+ nu_mu and tau+ nu_tau and report a search for the leptonic Ds+ to e+ nu_e decays. The results are obtained from a large data sample collected at or near the Y(4S) and Y(5S) resonances with the Belle detector at the KEKB asymmetric-energy e+e- collider. The branching fractions of hadronic decays are measured to be Br(Ds+ -> K- K+ pi+) = (5.06 +- 0.15 +- 0.21)%, Br(Ds+ -> anti-K0 K+) = (2.95 +- 0.11 +- 0.09)%, and Br(Ds+ -> eta pi+) = (1.82 +- 0.14 +- 0.07)%, where the first and second uncertainties are statistical and systematic, respectively. The branching fractions of leptonic decays are measured to be Br(Ds+ -> mu+ nu_mu) = (0.531 +- 0.028 +- 0.020)%, and Br(Ds+ -> tau+ nu_tau) = (5.70 +- 0.21 +0.31-0.30)%, which are combined to determine the Ds+ meson decay constant f_Ds = (255.5 +- 4.2 +- 5.1) MeV. We find no significant signal for Ds+ -> e+ nu_e decays and set an upper limit ...

  8. Intercalation of Epinephrine with Calf-thymus ds-DNA

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    A strong interaction between double stranded calf-thymus DNA (ds-DNA) and epinephrine but no interaction between single stranded calf-thymus DNA (ss-DNA) and epinephrine were observed by the use of UV-spectroscopy and cyclic voltammetry. It is suggested that the interaction leads to an intercalation of EP molecules into the groove of ds-DNA and the formation of ds-DNA(EP)n complex.

    We report on searches for B- --> Ds- Phi and B- --> Ds*- Phi. In the context of the Standard Model, these decays are expected to be highly suppressed since they proceed through annihilation of the b and u-bar quarks in the B- meson. Our results are based on 234 million Upsilon(4S) --> B Bbar decays collected with the BABAR detector at SLAC. We find no evidence for these decays, and we set Bayesian 90% confidence level upper limits on the branching fractions BF(B- --> Ds- Phi) Ds*- Phi)<1.2x10^(-5). These results are consistent with Standard Model expectations.

    This article describes improved measurements by CLEO of the $B^0 \\to D_s^+ D^{*-}$ and $B^0 \\to D_s^{*+} D^{*-}$ branching fractions, and first evidence for the decay $B^+ \\to D_s^{(*)+} \\bar{D}^{**0}$, where $\\bar{D}^{**0}$ represents the sum of the $\\bar{D}_1(2420)^0$, $\\bar{D}_2^*(2460)^0 $, and $\\bar{D}_1(j=1/2)^0$ L=1 charm meson states. Also reported is the first measurement of the $D_s^{*+}$ polarization in the decay $B^0 \\to D_s^{*+} D^{*-}$. A partial reconstruction technique, employing only the fully reconstructed $D_s^+$ and slow pion $\\pi_s^-$ from the $D^{*-} \\to \\bar{D}^0 \\pi^-_s$ decay, enhances sensitivity. The observed branching fractions are $ {\\mathcal B} (B^0 \\to D_s^+ D^{*-}) = (1.10 \\pm 0.18 \\pm 0.10 \\pm 0.28)%$, $ {\\mathcal B} (B^0 \\to D_s^{*+} D^{*-}) = (1.82 \\pm 0.37 \\pm 0.24 \\pm 0.46)%$, and $ {\\mathcal B} (B^+ \\to D_s^{(*)+} \\bar{D}^{**0}) = (2.73 \\pm 0.78 \\pm 0.48 \\pm 0.68)%$, where the first error is statistical, the second systematic, and the third is due to the uncertainty in th...

    The killer cell Ig-like receptor (KIR)-MHC class I pathway is an integral part of natural killer cell immunity, and its role in host protection from both cancer and infection is important In addition, we have shown elevated KIR2DS2 and 2DS4 expression in PBMCs of patients undergoing hematopoietic cell transplantation (HCT) [1]. Since all inhibitory KIR promoters are known to be heavily methylated, the question asked here is how and when KIR2DS2 and 2DS4 promoters had changed their methylation...

    2014-01-01

    The decay of a $B_{s}^{0}$ meson to two oppositely charged $D_{s}$ mesons is one that is postulated to be almost exclusively CP even. Measuring the properties of this decay can therefore give important information about the behaviour of the $B_{s}^{0}$ system. This poster presents two of these measurements, made by LHCb, using data from run 1 of the LHC.

  18. Molecular biology of maize Ac/Ds elements: an overview.

    Science.gov (United States)

    Lazarow, Katina; Doll, My-Linh; Kunze, Reinhard

    2013-01-01

    Maize Activator (Ac) is one of the prototype transposable elements of the hAT transposon superfamily, members of which were identified in plants, fungi, and animals. The autonomous Ac and nonautonomous Dissociation (Ds) elements are mobilized by the single transposase protein encoded by Ac. To date Ac/Ds transposons were shown to be functional in approximately 20 plant species and have become the most widely used transposable elements for gene tagging and functional genomics approaches in plants. In this chapter we review the biology, regulation, and transposition mechanism of Ac/Ds elements in maize and heterologous plants. We discuss the parameters that are known to influence the functionality and transposition efficiency of Ac/Ds transposons and need to be considered when designing Ac transposase expression constructs and Ds elements for application in heterologous plant species.

    An aerobic bacterial strain DS3, capable of growing on furfural as sole carbon source, was isolated from actived sludge of wastewater treatment plant in a diosgenin factory after enrichment. Based on morphological physiological tests as well as 16SrDNA sequence and Biolog analyses it was identified as Bacillus subtilis. The study revealed that strain DS3 utilized furfural, as analyzed by high-performance liquid chromatography (HPLC). Under following conditions: pH 8.0, temperature 35 degrees C, 150 rpm and 10% inoculum, strain DS3 showed 31.2% furfural degradation. Furthermore, DS3 strain was found to tolerate furfural concentration as high as 6000 mg(-1). The ability of Bacillus subtilis strain DS3 to degrade furfural has been demonstrated for the first time in the present study.

  1. Mutagenesis of barley malting quality QTLs with Ds transposons.

    Singh, Surinder; Tan, Han Qi; Singh, Jaswinder

    2012-03-01

    Various functional genomic tools are being used to identify and characterize genes in plants. The Activator/Dissociation (Ac/Ds) transposon-based approach offers great potential, especially in barley, due to its limited success of genetic transformation and its large genome size. The bias of the Ac/Ds system towards genic regions and its tendency toward localized transpositions can greatly enhance the discovery and tagging of genes linked to Ds. Barley is a key ingredient in malting and brewing industry; therefore, gene discovery in relation to malting has an industrial perspective. Malting quality in barley is a complex and quantitatively inherited trait. Two major quantitative trait loci (QTLs) affecting malting quality traits have been located on chromosome 4H. In this study, Ds was reactivated from parent transposants (TNP) lines, TNP-29 and TNP-79, where Ds was mapped in the vicinity of important malting QTLs. Reactivation of Ds was carried out both by conventional breeding and in vitro approaches. A threefold increase in reactivation frequency through the in vitro approach enabled the development of a new genomic resource for the dissection of malting QTL and gene discovery in barley. Identification of unique flanking sequences, using high-efficiency thermal asymmetric interlaced PCR and inverse PCR from these populations, has further emphasized the new location of Ds in the barley genome and provided new transposon mutants especially in β-GAL1, β-amylase-like gene and ABC transporter for functional genomic studies.

    Our group has reported a high incidence of reactive hypoglycemia following Roux-en-Y gastric bypass (RYGB) with specific interest in postprandial insulin and the ratio of 1- to 2-h serum glucose levels. The purpose of this study is to compare the 6-month response to oral glucose challenge in patients undergoing RYGB, duodenal switch (DS), and vertical sleeve gastrectomy (VSG). Thirty-eight patients meeting the NIH criteria for bariatric surgery who have reached the 6-month postoperative mark are the basis of this report. Preoperatively and at 6 months follow-up, patients underwent blood draw to determine levels of fasting glucose, fasting insulin, HbA1c, C peptide, and 2 h oral liquid glucose challenge test (OGTT). HOMA-IR and 1 to 2 h ratios of glucose and fasting to 1 h ratio of insulin were calculated. All patients underwent a successful laparoscopic bariatric procedure (VSG =13, DS =13, and RYGB = 12). All operations reduced BMI, HgbA1c, fasting glucose, and fasting insulin. HOMA IR and glucose tolerance improved with all procedures. In response to OGTT at 6 months, there was a 20-fold increase in insulin at 1 h in RYGB, which was not seen in DS. At 6 months, 1-h insulin was markedly lower in DS (p DS (p DS (p DS causes a much lower rise in 1-h insulin, with this difference being statistically significant at p DS results in a less abrupt reduction in blood glucose. Although 1-h insulin is lower, DS patients had the lowest HbA1C at 6 months (p < .05). We believe that these findings have important implications for the choice of bariatric procedure for both diabetic and non-diabetic patients.

    2009-01-01

    Masses of the Ds(0±) mesons are investigated from a view-point of ordinary light-heavy system in the framework of the Gaussian sum rules, which are worked out by means of the Laplacian transformation to the usual Borel sum rules. Using the standard input of QCD non-perturbative parameters, the corresponding mass spectra and couplings of the currents to the Ds(0±) mesons are obtained. Our results are mDs(O-) = 1.968±0.016±0.003 GeV and mDs(0+) = 2.320±0.014v0.003 GeV, which are in good accordance with the experimental data, 1.969 GeV and 2.317 GeV.

    We search for the semi-inclusive process Bs0-->Ds(*)Ds(*) using 2.8 fb(-1) of pp collisions at sqrt[s]=1.96 TeV recorded by the D0 detector operating at the Fermilab Tevatron Collider.

    Doublecortin (DCX) is predominantly expressed in neuronal precursor cells and young immature neurons of the developing and adult brain, where it is involved in neuronal differentiation, migration and plasticity. Moreover, its expression pattern reflects neurogenesis, and transgenic DCX promoter-driven reporter models have been previously used to investigate adult neurogenesis. In this study, we characterize dsRed2 reporter protein-expressing cells in the adult retina of the transgenic DCX promoter-dsRed2 rat model, with the aim to identify cells with putative neurogenic activity. Additionally, we confirmed the expression of the dsRed2 protein in DCX-expressing cells in the adult hippocampal dentate gyrus. Adult DCX-dsRed2 rat retinas were analyzed by immunohistochemistry for expression of DCX, NF200, Brn3a, Sox2, NeuN, calbindin, calretinin, PKC-a, Otx2, ChAT, PSA-NCAM and the glial markers GFAP and CRALBP, followed by confocal laser-scanning microscopy. In addition, brain sections of transgenic rats were analyzed for dsRed2 expression and co-localization with DCX, NeuN, GFAP and Sox2 in the cortex and dentate gyrus. Endogenous DCX expression in the adult retina was confined to horizontal cells, and these cells co-expressed the DCX promoter-driven dsRed2 reporter protein. In addition, we encountered dsRed2 expression in various other cell types in the retina: retinal ganglion cells (RGCs), a subpopulation of amacrine cells, a minority of bipolar cells and in perivascular cells. Since also RGCs expressed dsRed2, the DCX-dsRed2 rat model might offer a useful tool to study RGCs in vivo under various conditions. Müller glial cells, which have previously been identified as cells with stem cell features and with neurogenic potential, did express neither endogenous DCX nor the dsRed2 reporter. However, and surprisingly, we identified a perivascular glial cell type expressing the dsRed2 reporter, enmeshed with the glia/stem cell marker GFAP and colocalizing with the

    Since their discovery in 2003, the open charm states $D_{s0}^*(2317)$ and $D_{s1}(2460)$ provide a challenge to the conventional quark model. In recent years, theoretical evidence has been accumulated for both states in favor of a predominantly $DK$ and $D^*K$ molecular nature, respectively. However, a direct experimental proof of this hypothesis still needs to be found. Since radiative decays are generally believed to be sensitive to the inner structure of the decaying particles, we study in this work the radiative and strong decays of both the $D_{s0}^*(2317)$ and $D_{s1}(2460)$, as well as of their counterparts in the bottom sector. While the strong decays are indeed strongly enhanced for molecular states, the radiative decays are of similar order of magnitude in different pictures. Thus, the experimental observable that allows one to conclusively quantify the molecular components of the $D_{s0}^*(2317)$ and $D_{s1}(2460)$ is the hadronic width, and not the radiative one, in contradistinction to common bel...

    A closely-linked pair of Ac/Ds elements induces chromosomal rearrangements in Arabidopsis and maize. This report summarizes the Ac/Ds systems that generate an exceptionally high frequency of chromosomal rearrangements in rice genomes. From a line containing a single Ds element inserted at the OsRLG5 locus, plants containing a closely-linked pair of inversely-oriented Ds elements were obtained at 1% frequency among the population regenerated from tissue culture. Subsequent regeneration of the lines containing cis-paired Ds elements via tissue culture led to a high frequency (35.6%) of plants containing chromosomal rearrangements at the OsRLG5 locus. Thirty-four rearrangement events were characterized, revealing diverse chromosomal aberrations including deletions, inversions and duplications. Many rearrangements could be explained by sister chromatid transposition (SCT) and homologous recombination (HR), events previously demonstrated in Arabidopsis and maize. In addition, novel events were detected and presumably generated via a new alternative transposition mechanism. This mechanism, termed single chromatid transposition (SLCT), resulted in juxtaposed inversions and deletions on the same chromosome. This study demonstrated that the Ac/Ds system coupled with tissue culture-mediated plant regeneration could induce higher frequencies and a greater diversity of chromosomal rearrangements than previously reported. Understanding transposon-induced chromosomal rearrangements can provide new insights into the relationship between transposable elements and genome evolution, as well as a means to perform chromosomal engineering for crop improvement. Rice is a staple cereal crop worldwide. Complete genome sequencing and rich genetic resources are great advantages for the study of the genomic complexity induced by transposable elements.(1) (-) (2) The combination of tissue culture with genetic lines carrying a pair of closely located Ac/Ds elements greatly increases the

  17. Unique Thermal Stability of Unnatural Hydrophobic Ds Bases in Double-Stranded DNAs.

    Genetic alphabet expansion technology, the introduction of unnatural bases or base pairs into replicable DNA, has rapidly advanced as a new synthetic biology area. A hydrophobic unnatural base pair between 7-(2-thienyl)imidazo[4,5-b]pyridine (Ds) and 2-nitro-4-propynylpyrrole (Px) exhibited high fidelity as a third base pair in PCR. SELEX methods using the Ds-Px pair enabled high-affinity DNA aptamer generation, and introducing a few Ds bases into DNA aptamers extremely augmented their affinities and selectivities to target proteins. Here, to further scrutinize the functions of this highly hydrophobic Ds base, the thermal stabilities of double-stranded DNAs (dsDNA) containing a noncognate Ds-Ds or G-Ds pair were examined. The thermal stability of the Ds-Ds self-pair was as high as that of the natural G-C pair, and apart from the generally higher stability of the G-C pair than that of the A-T pair, most of the 5'-pyrimidine-Ds-purine-3' sequences, such as CDsA and TDsA, exhibited higher stability than the 5'-purine-Ds-pyrimidine-3' sequences, such as GDsC and ADsC, in dsDNAs. This trait enabled the GC-content-independent control of the thermal stability of the designed dsDNA fragments. The melting temperatures of dsDNA fragments containing the Ds-Ds pair can be predicted from the nearest-neighbor parameters including the Ds base. In addition, the noncognate G-Ds pair can efficiently distinguish its neighboring cognate natural base pairs from noncognate pairs. We demonstrated that real-time PCR using primers containing Ds accurately detected a single-nucleotide mismatch in target DNAs. These unique properties of the Ds base that affect the stabilities of the neighboring base pairs could impart new functions to DNA molecules and technologies.

    Using data collected near the Ds*+ Ds- peak production energy Ecm = 4170 MeV by the CLEO-c detector, we study the decays of Ds+ mesons to two pseudoscalar mesons. We report on searches for the singly-Cabibbo-suppressed Ds+ decay modes K+ eta, K+ eta', pi+ K0S, K+ pi0, and the isospin-forbidden decay mode Ds+ to pi+ pi0. We normalize with respect to the Cabibbo-favored Ds+ modes pi+ eta, pi+ eta', and K+ K0S, and obtain ratios of branching fractions: Ds+ to K+ eta / Ds+ to pi+ eta = (8.9 +- 1.5 +- 0.4)%, Ds+ to K+ eta' / Ds+ to pi+ eta' = (4.2 +- 1.3 +- 0.3)%, Ds+ to pi+ K0S / Ds+ to K+ K0S = (8.2 +- 0.9 +- 0.2)%, Ds+ to K+ pi0 / Ds+ to K+ K0S = (5.0 +- 1.2 +- 0.6)%, and Ds+ to pi+ pi0 / Ds+ to K+ K0S < 4.1% at 90% CL, where the uncertainties are statistical and systematic, respectively.

    In exonization events, Ds1 may provide donor and/or acceptor sites for splicing after inserting into genes and be incorporated into new transcripts with new exon(s). In this study, the protein variants of Ds1 exonization yielding additional functional profile(s) were studied. Unlike Ds exonization, which creates new profiles mostly by incorporating flanking intron sequences with the Ds message, Ds1 exonization additionally creates new profiles through the presence or absence of Ds1 messages. The number of unique functional profiles harboring Ds1 messages is 1.3-fold more than that of functional profiles without Ds1 messages. The highly similar 11 protein isoforms at a single insertion site also contribute to proteome complexity enrichment by exclusively creating new profiles. Particularly, Ds1 exonization produces 459 unique profiles, of which 129 cannot be built by Ds. We thus conclude that Ds and Ds1 are independent but synergistic in their capacity to enrich proteome complexity through exonization.

    We have searched for the rare decay B+ --> Ds+ pi0. The analysis is based on a sample of 232 million Upsilon(4S) --> B anti-B decays collected with the BABAR detector at the PEP-II e+ e- storage ring. We find 19.6 signal events, corresponding to a significance of 4.7 sigma. The extracted signal yield including statistical and systematic uncertainties is 20.1+6.8+0.4 -6.0-1.5, and we measure B(B+ --> Ds+ pi0) =(1.5 +0.5 -0.4 +- 0.1 +- 0.2) 10^-5, where the first uncertainty is statistical, the second is systematic, and the last is due to the uncertainty on the Ds+ decay and its daughter decay branching fractions.

    A Dalitz plot analysis of approximately 13 000 Ds+ decays to π+π-π+ has been performed. The analysis uses a 384fb-1 data sample recorded by the BABAR detector at the PEP-II asymmetric-energy e+e- storage ring running at center of mass energies near 10.6 GeV. Amplitudes and phases of the intermediate resonances which contribute to this final state are measured. A high precision measurement of the ratio of branching fractions is performed: B(Ds+→π+π-π+)/B(Ds+→K+K-π+)=0.199±0.004±0.009. Using a model-independent partial wave analysis, the amplitude and phase of the S wave have been measured.

  4. Blind Adaptive Successive Interference Cancellation for Multicarrier DS-CDMA

    2011-01-01

    A new adaptive receiver design for the Multicarrier (MC) DS-CDMA is proposed employing successive interference cancellation (SIC) architecture. One of the main problems limiting the performance of SIC in MC DS-CDMA is the imperfect estimation of multiple access interference (MAI), and hence, the limited frequency diversity gain achieved in multipath fading channels. In this paper, we design a blind adaptive SIC with new multiple access interference suppression capability implemented within despreading process to improve both detection and cancellation processes. Furthermore, dynamic scaling factors derived from the despreader weights are used for interference cancellation process. This method applied on each subcarrier is followed by maximum ratio or equal gain combining to fully exploit the frequency diversity inherent in the multicarrier CDMA systems. It is shown that this way of MAI estimation on individual subcarrier provides significantly improved performance for a MC DS-CDMA system compared to that with...

  5. Higher spin realization of the DS/CFT correspondence

    We conjecture that Vasiliev’s theory of higher spin gravity in four-dimensional de Sitter space (dS4) is holographically dual to a three-dimensional conformal field theory (CFT3) living on the spacelike boundary of dS4 at future timelike infinity. The CFT3 is the Euclidean Sp(N) vector model with anticommuting scalars. The free CFT3 flows under a double-trace deformation to an interacting CFT3 in the IR. We argue that both CFTs are dual to Vasiliev dS4 gravity but with different future boundary conditions on the bulk scalar field. Our analysis rests heavily on analytic continuations of bulk and boundary correlators in the proposed duality relating the O(N) model with Vasiliev gravity in AdS4.

  6. Options for the SELEX state DsJ+(2632)

    We consider possible assignments for the DsJ+(2632), which was recently reported in Ds+η and DK final states by the SELEX Collaboration at Fermilab. The most plausible quark model assignment for this state is the first radial excitation ( 2S) of the csbarDs*(2112), although the predicted mass and strong decay branching fractions for this assignment are not in agreement with the SELEX data. The reported dominance of Dη over DK appears especially problematic. An intriguing similarity to the K(1414) is noted. 2S- D3 configuration mixing is also considered, and we find that this effect is unlikely to resolve the branching fraction discrepancy. Other interpretations as a csbar-hybrid or a two-meson molecule are also considered, but appear unlikely. Thus, if this state is confirmed, it will require reconsideration of the systematics of charmed meson spectroscopy and strong decays.

  7. The $KD$, $\\eta D_s$ interaction in finite volume and the $D_{s^* 0}(2317)$ resonance

    An SU(4) extrapolation of the chiral unitary theory in coupled channels done to study the scalar mesons in the charm sector is extended to produce results in finite volume. The theory in the infinite volume produces dynamically the $D_{s^*0}(2317)$ resonance by means of the coupled channels $KD$, $\\eta D_s$. Energy levels in the finite box are evaluated and, assuming that they would correspond to lattice results, the inverse problem of determining the bound states and phase shifts in the infinite volume from the lattice data is solved. We observe that it is possible to obtain accurate $KD$ phase shifts and the position of the $D_{s^*0}(2317)$ state, but it requires the explicit consideration of the two coupled channels in the analysis if one goes close to the $\\eta D_s$ threshold. We also show that a careful analysis of the finite volume data can shed some light on the nature of the $D_{s^*0}(2317)$ resonance as a $KD$ molecule or otherwise.

We measure the branching fractions B(B{0}-->D{s}{+}pi-)=(1.3+/-0.3(stat)+/-0.2(syst))x10(-5), B(B{0}-->D{s}{-} K+)=(2.5+/-0.4(stat)+/-0.4(syst))x10(-5), B(B{0}-->D{s}{*+}pi-)=(2.8+/-0.6(stat)+/-0.5(syst))x10(-5), and B(B{0}-->D{s}{*-}K+)=(2.0+/-0.5(stat)+/-0.4(syst))x10(-5). The significances of the measurements to differ from zero are 5, 9, 6, and 5 standard deviations, respectively. This is the first observation of B{0}-->D{s}{+}pi-, B{0}-->D{s}{*+}pi-, and B{0}-->D{s}{*-}K+ decays.

    We have measured the vector-pseudoscalar mass splitting M(D.sub(s).sup(*+))- M(D.sub(s).sup(+)) =144.22\\pm 0.47\\pm 0.37 MeV, significantly more precise than the previous world average. We minimize the systematic errors by also measuring the vector-pseudoscalar mass difference M(D^{*0})-M(D^0) using the radiative decay D^{*0}\\rightarrow D^0\\gamma, obtaining [M(D_s^{*+})-M(D_s^+)]- [M(D^{*0})-M(D^0)] = 2.09\\pm 0.47\\pm 0.37 MeV. This is then combined with our previous high-precision measurement of M(D^{*0})-M(D^0), which used the decay D^{*0}\\rightarrow D^0\\pi^0. We also measure the mass difference M(D_s^+)-M(D^+)=99.5\\pm 0.6\\pm 0.3 MeV, using the \\phi\\pi^+ decay modes of the D_s^+ and D^+ mesons. hardcopies with figures can be obtained upon written request to: Pam Morehouse preprint secretary Newman Lab Cornell University Ithaca, NY 14853 or by sending mail to: preprints@lns62.lns.cornell.edu

    Heavy quark production in 7 TeV centre-of-mass energy $pp$ collisions at the LHC is not necessarily flavour symmetric. The production asymmetry, $A_P$, between $D_s^+$ and $D_s^-$ mesons is studied using the $\\phi\\pi^\\pm$ decay mode in a data sample of 1.0 fb$^{-1}$ collected with the LHCb detector. The difference between $\\pi^+$ and $\\pi^-$ detection efficiencies is determined using the ratios of fully reconstructed to partially reconstructed $D^{*\\pm}$ decays. The overall production asymmetry in the $D_s$ rapidity region 2.0 to 4.5 with transverse momentum larger than 2 GeV is measured to be $A_P=(-0.33 \\pm 0.22 \\pm 0.10)\\%$. This result can constrain models of heavy flavour production.

    It is recalled that a ten year old calculation of all meson masses may explain the low value of the recently discovered Ds(2317) meson. This calculation was based on a fully relativistic quasiparticle theory, which has been applied to a large number of bound state problems and scattering processes.

    Autism and behavioral characteristics in adults with Dravet syndrome (DS) have rarely been systematically studied. Three scales were used to assess the outcomes of DS in adulthood in terms of autism and behavior. All the adult patients with DS, nine male and four female, aged between 18 and 60 years, living at the Epilepsy Center Kempenhaeghe in The Netherlands were included in the study. In addition, the past medical history of each patient was systematically screened for diagnoses like autism, Pervasive Development Disorder-Not Otherwise Specified (PDD-NOS), autism spectrum disorder (ASD), hyperactivity, Attention Deficit Hyperactivity Disorder (ADHD), and self-mutilation. Information concerning past and current use of psychoactive drugs was also evaluated. Eight patients (61.5%) were classified as having autism spectrum disorder (ASD) according to the AVZ-R or according to the medical record. Self-mutilation was seen in four patients (30.8%), hyperactivity in none. Three patients (23.1%) currently used psychoactive drugs. Autism spectrum disorders persist in adult patients with DS, while certain characteristics associated with behavioral problems, such as hyperactivity or use of psychoactive medication, seem to be less prominent than in childhood.

    Src-like adaptor protein (SLAP) adapts c-Cbl, an E3 ubiquitin ligase, to activated components of the BCR signaling complex regulating BCR levels and signaling in developing B cells. Based on this function, we asked whether SLAP deficiency could decrease the threshold for tolerance and eliminate development of autoreactive B cells in two models of autoantibody production. First, we sensitized mice with a dsDNA mimetope that causes an anti-dsDNA response. Despite equivalent production of anti-peptide antibodies compared to BALB/c controls, SLAP(-/-) mice did not produce anti-dsDNA. Second, we used the 56R tolerance model. SLAP(-/-) 56R mice had decreased levels of dsDNA-reactive antibodies compared to 56R mice due to skewed light chain usage. Thus, SLAP is a critical regulator of B-cell development and function and its deficiency leads to decreased autoreactive B cells that are otherwise maintained by inefficient receptor editing or failed negative selection.

    A combined mass and particle identification fit is used to make the first observation of the decay B¯s0→Ds±K∓ and measure the branching fraction of B¯s0→Ds±K∓ relative to B¯s0→Ds+π-. This analysis uses 1.2fb-1 integrated luminosity of pp¯ collisions at s=1.96TeV collected with the CDF II detector at the Fermilab Tevatron collider. We observe a B¯s0→Ds±K∓ signal with a statistical significance of 8.1σ and measure B(B¯s0→Ds±K∓)/B(B¯s0→Ds+π-)=0.097±0.018(stat)±0.009(syst).

    The branching fractions of Ds meson decays serve to normalize many measurements of processes involving charm quarks. Using 586 pb^-1 of e+ e- collisions recorded at a center of mass energy of 4.17 GeV, we determine absolute branching fractions for 13 Ds decays in 16 reconstructed final states with a double tag technique. In particular we make a precise measurement of the branching fraction B(Ds -> K- K+ pi+) = (5.55 +- 0.14 +- 0.13)%, where the uncertainties are statistical and systematic respectively. We find a significantly reduced value of B(Ds -> pi+ pi0 eta') compared to the world average, and our results bring the inclusively and exclusively measured values of B(Ds -> eta' X)$ into agreement. We also search for CP-violating asymmetries in Ds decays and measure the cross-section of e+ e- -> Ds* Ds at Ecm = 4.17 GeV.

    Two series of sodium carboxymethyl celluloses (NaCMCs) derived from microcrystalline cellulose (Avicel samples, DP~160) and cotton linters (BWL samples, DP~1400) with average degrees of substitution in the range DS=0.45-1.55 were analyzed by gradient liquid adsorption chromatography (gradient LAC) in order to determine their chemical composition distributions (DS distributions or 1st order heterogeneities). Clear separations of samples having different average DS values were achieved for both sample series, allowing determination of the DS distributions of the samples. A slight molar mass influence on the eluent composition at elution was observed. From the DS distributions the DS standard deviations were calculated and taken as a measure for the extent of chemical heterogeneity of the single samples. While no noticeable dependence of the chemical heterogeneity on average DS was observed for Avicels, the heterogeneity decreases with increasing average DS for BWLs. Copyright © 2013 Elsevier Ltd.

  11. Radiative Leptonic Decay of Ds and D Mesons

    Barik, N.; Naimuddin, Sk.; Dash, P. C.

    The radiative leptonic decays Ds → μνμγ and D → μνμγ are investigated at the tree level within the relativistic independent quark model based on the confining potential in the scalar-vector harmonic form. The branching ratios for these decays in the vanishing lepton mass limit are obtained as ℬr(Ds → μνμγ) = 4.94×10-4 and ℬr(D → μνμγ) = 3.34×10-5, which includes the contributions of the internal bremsstrahlung and structure dependent diagrams at the level of the quark constituents. Finally, the photon energy spectra as predicted here is found to be symmetric about the peak value of the photon energy at Eγ = MD_(s)/4.

    2010-01-01

    Commercial cellular networks, like the systems based on DS-CDMA, face many types of interferences such as multi-user interference inside each sector in a cell to interoperate interference. Independent Component Analysis (ICA) has been used as an advanced preprocessing tool for blind suppression of interfering signals in DS-CDMA communication systems. The role of ICA is to provide an interference-mitigated signal to the conventional detection. This paper evaluates the performance of some major ICA algorithms like Cardoso's joint approximate diagonalization of eigen matrices (JADE), Hyvarinen's fixed point algorithm and Comon's algorithm to solve the symbol estimation problem of the multi users in a DSCDMA communication system. The main focus is on blind separation of convolved CDMA mixture and the improvement of the downlink symbol estimation. The results of numerical experiment are compared with those obtained by the Single User Detection (SUD) receiver, ICA detector and combined SUD-ICA detector.

    Newly observed two charmed-strange resonances, $D_{s1}^*(2860)$ and $D_{s3}^*(2860)$, are investigated by calculating their Okubo-Zweig-Iizuka allowed strong decays, which shows that they are suitable candidates for the $1^3D_1$ and $1^3D_3$ states in the charmed-strange meson family. Our study also predicts other main decay modes of $D_{s1}^*(2860)$ and $D_{s3}^*(2860)$, which can be accessible at the future experiment. In addition, the decay behaviors of the spin partners of $D_{s1}^*(2860)$ and $D_{s3}^*(2860)$, i.e., $1D(2^-)$ and $1D^\\prime(2^-)$, are predicted in this work, which are still missing at present. Experimental search for the missing $1D(2^-)$ and $1D^\\prime(2^-)$ charmed-strange mesons is an intriguing and challenging task for further experiment.

    The (Delta I = 1) decay D_s^* --> Ds pi0 and (\\Delta I = 0) decay D_s^* --> Ds gamma have been reconstructed using 90.4 fb^-1 of data recorded by the BaBar detector at the PEP-II asymmetric-energy e^+e^- collider. The relative branching fraction of isospin violating decay to isospin conserving decay has been measured. Our preliminary result for this ratio is Gamma(D_s^* -> D_s pi0)/Gamma(D_s^* --> D_s gamma) = 0.0621 +/- 0.0049 (stat) +/- 0.0063 (syst). In addition we reconstruct the decays D^* --> D0 pi0 and D^* --> D0 gamma for completeness and measure a preliminary relative branching fraction to be Gamma(D^* --> D0 pi0)/Gamma(D&* --> D0 gamma) = = 1.740 +/- 0.020 (stat) +/- 0.125 (syst). Both measurements represent significant improvements over present world averages.

    Half a century ago, the sedative thalidomide caused a serious drug disaster because of its teratogenicity and was withdrawn from the market. However, thalidomide, which has returned to the market, is now used for the treatment of leprosy and multiple myeloma (MM) under strict control. The mechanism of thalidomide action had been a long-standing question. We developed a new affinity bead technology and identified cereblon (CRBN) as a thalidomide-binding protein. We found that CRBN functions as a substrate receptor of an E3 cullin-Ring ligase complex 4 (CRL4) and is a primary target of thalidomide teratogenicity. Recently, new thalidomide derivatives, called immunomodulatory drugs (IMiDs), have been developed by Celgene. Among them, lenalidomide (Len) and pomalidomide (Pom) were shown to exert strong therapeutic effects against MM. It was found that Len and Pom both bind CRBN-CRL4 and recruit neomorphic substrates (Ikaros and Aiolos). More recently it was reported that casein kinase 1a (Ck1a) was identified as a substrate for CRBN-CRL4 in the presence of Len, but not Pom. Ck1a breakdown explains why Len is specifically effective for myelodysplastic syndrome with 5q deletion. It is now proposed that binding of IMiDs to CRBN appears to alter the substrate specificity of CRBN-CRL4. In this review, we introduce recent findings on IMiDs.

    We present a measurement of the CP-violating weak mixing phase ϕs using the decay Bs(0)→Ds(+)Ds(-) in a data sample corresponding to 3.0 fb(-1) of integrated luminosity collected with the LHCb detector in pp collisions at center-of-mass energies of 7 and 8 TeV. An analysis of the time evolution of the system, which does not use the constraint |λ|=1 to allow for the presence of CP violation in decay, yields ϕs=0.02±0.17(stat)±0.02(syst)  rad, |λ|=0.91(-0.15)(+0.18)(stat)±0.02(syst). This result is consistent with the standard model expectation.

    The measurement of the inclusive branching fraction of $B0s \\to Ds^{(*)+} Ds^{(*)-}$ decay together with its contribution to the determination of $\\Delta \\Gamma{s}/ \\Gamma {s}$ are presented. The branching fraction value is compatible with results from previous experiments, improving the world average. The $B0 \\to D^+D^-$ and $B0 \\to D^*D^{(*)}$ decays are used to measure the parameters associated with $CP$ Violation in those channels; while the analysis associated to the second channel is at an initial stage the first one is almost concluded, the values obtained for the sensitivity on the $CP$ observables show that LHCb can rival the results obtained by previous experiments.

  4. Polymorphism of viral dsRNA in Xanthophyllomyces dendrorhous strains isolated from different geographic areas

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available Abstract Background Strains of the astaxanthin producing yeast Xanthophyllomyces dendrorhous have been isolated from different cold regions around the earth, and the presence of double stranded RNA (dsRNA elements was described in some isolates. This kind of viruses is widely distributed among yeasts and filamentous fungi and, although generally are cryptic in function, their studies have been a key factor in the knowledge of important fungi. In this work, the characterization and genetic relationships among dsRNA elements were determined in strains representatives of almost all regions of the earth where X. dendrorhous have been isolated. Results Almost all strains of X. dendrorhous analyzed carry one, two or four dsRNA elements, of molecular sizes in the range from 0.8 to 5.0 kb. Different dsRNA-patterns were observed in strains with different geographic origin, being L1 (5.0 kb the common dsRNA element. By hybridization assays a high genomic polymorphism was observed among L1 dsRNAs of different X. dendrorhous strains. Contrary, hybridization was observed between L1 and L2 dsRNAs of strains from same or different regions, while the dsRNA elements of minor sizes (M, S1, and S2 present in several strains did not show hybridization with neither L1 or L2 dsRNAs. Along the growth curve of UCD 67-385 (harboring four dsRNAs an increase of L2 relative to L1 dsRNA was observed, whiles the S1/L1 ratio remains constant, as well as the M/L1 ratio of Patagonian strain. Strains cured of S2 dsRNA were obtained by treatment with anisomycin, and comparison of its dsRNA contents with uncured strain, revealed an increase of L1 dsRNA while the L2 and S1 dsRNA remain unaltered. Conclusion The dsRNA elements of X. dendrorhous are highly variable in size and sequence, and the dsRNA pattern is specific to the geographic region of isolation. Each L1 and L2 dsRNA are viral elements able to self replicate and to coexist into a cell, and L1 and S2 dsRNAs elements could

    To investigate the effect of M-ds-P21 on the apoptosis of bladder cancer T24 cells and its potential mechanism. Effect of M-ds-P21 on T24 cells were assessed by cell morphology and Western blot. Apoptosis was quantified by Annexin-V flow-cytometry analysis. To uncover the role of P53 in M-ds-P21-mediated apoptosis of T24 cells, we knocked down P53 before treating cells with M-ds-P21, and then assayed P21 and apoptosis-related protein by Western blot. To uncover the mechanism by which M-ds-P21 played stronger effect than ds-P21, we performed confocal microscope analyses. Both M-ds-P21 and ds-P21 treatment changed the cell morphology, leading to cell apoptosis after 3 days. Apoptosis induced by M-ds-P21 and ds-P21 treatment is not P53-dependent but caspase-dependent. Compared with ds-P21, M-ds-P21 significantly increased the bioavailability of ds-RNA in T24 cells. M-ds-P21 treatment induces more apoptotic population than ds-P21 does. The mechanism for stronger effect of M-ds-P21 is partly due to the enhanced bioavailability of ds-RNA in human bladder cancer T24 cells, and not P53-dependent but caspase-dependent.

In the selection of the solution implemented in the frame of every mission, a key driver is the degree of advance in the test performed over flight representative battery modules regarding their safe behavior when deeply depleted after a long period in orbit with the passivation applied over the spacecraft.

    2013-05-01

    In August 2012, the Health Resources and Services Administration's Division of Nursing hosted a 2-day conference to discuss the three Ds: workforce diversity, social determinants, and health disparities that nurses face every day. In particular they wanted to begin a discussion on how nursing, which is still afield of little diversity, must address the needs of a nation that is quite diverse. The framework of the discussion focused around the need to address health in its complexity of the social determinants and health disparities that exist. The purpose of this article is to personalize these concepts to school nurses.

    A study of charm fragmentation into $D_s^{*+}$ and $D_s^+$ in $e^+e^-$ annihilations at $\\sqrt{s}$=10.5 GeV is presented. This study using $4.72 \\pm 0.05$ fb$^{-1}$ of CLEO II data reports measurements of the cross-sections $\\sigma(D_s^{*+})$ and $\\sigma(D_s^+)$ in momentum regions above $x=0.44$, where $x$ is the $D_s$ momentum divided by the maximum kinematically allowed $D_s$ momentum. The $D_s$ vector to vector plus pseudoscalar production ratio is measured to be $P_V(x(D_s^+)>0.44)=0.44\\pm0.04$

    In a data sample of approximately 1.3 fb-1 collected with the D0 detector between 2002 and 2006, the orbitally excited charm state D_s1(2536) has been observed with a measured mass of 2535.7 +/- 0.6 (stat) +/- 0.5 (syst) MeV via the decay mode B0_s -> D_s1(2536) mu nu X. A first measurement is made of the branching ratio product Br(b(bar) -> D_s1(2536) mu nu X).Br(D_s1(2536)->D* K0_S). Assuming that D_s1(2536) production in semileptonic decay is entirely from B0_s, an extraction of the semileptonic branching ratio Br(B0_s -> D_s1(2536) mu nu X) is made.

    It is shown, using a track-level simulation, that the use of the $D_s^- \\to K^{*0}K^-$ decay channel for $D_s^-$ reconstruction, in additioon with the previously studied $D_s^- \\to \\phi \\pi^-$ mode, enables two fold gain in the ATLAS $B_s^0$-mixing signal statistics through $B_s^0 \\to D_s^-a_1$ $B_s^0$-decay channel. A new modification of the amplitude fit method is suggested for the $x_s$ determination. Some general aspects of the $B_s^0$-mixing phenomenon is illustrated by pictures of Casimir Malevich, Maurits Cornelis Escher and Salvador Dali.

    Double-stranded RNA (dsRNA) is produced by almost all viruses during their replicative cycle and is a potent inducer of the innate antiviral immune response including inducing expression of type I interferons (IFNs) and interferon-stimulated genes (ISGs). During lytic virus infections intracellular dsRNA can escape into the extracellular space, where surface pattern recognition receptors, such as class A scavenger receptors (SR-As) facilitate its binding and entry into neighbouring cells. Studying extracellular dsRNA entry is difficult due to the ubiquitous expression profile and compensatory dsRNA binding characteristics of SR-As; a SR-A deficient cell line has yet to be identified. The present study suggests the Chinook salmon embryonic cell line, CHSE-214, as a model for studying extracellular dsRNA sensing in vitro. CHSE-214 is unable to bind and respond to extracellular dsRNA, can only respond to dsRNA when it is transfected into the cells, and is able to bind dsRNA when overexpressing human SR-AI. The applications for this model could include elucidating: dsRNA binding and entry mechanisms, including sequence and length effects, as well as SR-A and other putative surface dsRNA receptor ligand binding studies.

  14. Binding by TRBP-dsRBD2 Does Not Induce Bending of Double-Stranded RNA.

    Protein-nucleic acid interactions are central to a variety of biological processes, many of which involve large-scale conformational changes that lead to bending of the nucleic acid helix. Here, we focus on the nonsequence-specific protein TRBP, whose double-stranded RNA-binding domains (dsRBDs) interact with the A-form geometry of double-stranded RNA (dsRNA). Crystal structures of dsRBD-dsRNA interactions suggest that the dsRNA helix must bend in such a way that its major groove expands to conform to the dsRBD's binding surface. We show through isothermal titration calorimetry experiments that dsRBD2 of TRBP binds dsRNA with a temperature-independent observed binding affinity (KD ∼500 nM). Furthermore, a near-zero observed heat capacity change (ΔCp = 70 ± 40 cal·mol(-1)·K(-1)) suggests that large-scale conformational changes do not occur upon binding. This result is bolstered by molecular-dynamics simulations in which dsRBD-dsRNA interactions generate only modest bending of the RNA along its helical axis. Overall, these results suggest that this particular dsRBD-dsRNA interaction produces little to no change in the A-form geometry of dsRNA in solution. These results further support our previous hypothesis, based on extensive gel-shift assays, that TRBP preferentially binds to sites of nearly ideal A-form structure while being excluded from sites of local deformation in the RNA helical structure. The implications of this mechanism for efficient micro-RNA processing will be discussed.

  15. Immunomodulatory Drugs (IMiDs) in Multiple Myeloma.

    Multiple myeloma (MM) is a plasma cell neoplasm that is incurable with conventional therapy. However, the treatment of MM has dramatically changed since the emergence of immunomodulatory drugs and proteasome inhibitors. The improvements in survival are linked to a deeper understanding of the molecular mechanisms of the disease. Thalidomide, although highly active in MM, is associated with considerable toxicity, particularly in older patients. Immunomodulatory drugs (IMiDs) are structural and functional analogues of thalidomide that represent a promising new class of immunomodulators for treatment of a variety of inflammatory, autoimmune, and neoplastic diseases. Lenalidomide, a second generation IMiD, is more potent and has a better toxicity profile than thalidomide. It is commonly used in newly-diagnosed multiple myeloma, relapse refractory myeloma and as maintenance therapy after autologous stem cell transplantation (ASCT). Pomalidomide, a third generation IMiD, is 10 times more potent than lenalidomide and has already shown impressive results in patients who are heavily pre-treated and refractory to both lenalidomide and bortezomib. Here we provide a comprehensive review on IMiDs including molecular mechanisms, recent advances in therapeutic applications and management of toxicities in the treatment of MM.

  16. RIG-I and dsRNA-induced IFNbeta activation.

    Directory of Open Access Journals (Sweden)

    Full Text Available Except for viruses that initiate RNA synthesis with a protein primer (e.g., picornaviruses, most RNA viruses initiate RNA synthesis with an NTP, and at least some of their viral (pppRNAs remain unblocked during the infection. Consistent with this, most viruses require RIG-I to mount an innate immune response, whereas picornaviruses require mda-5. We have examined a SeV infection whose ability to induce interferon depends on the generation of capped dsRNA (without free 5' tri-phosphate ends, and found that this infection as well requires RIG-I and not mda-5. We also provide evidence that RIG-I interacts with poly-I/C in vivo, and that heteropolymeric dsRNA and poly-I/C interact directly with RIG-I in vitro, but in different ways; i.e., poly-I/C has the unique ability to stimulate the helicase ATPase of RIG-I variants which lack the C-terminal regulatory domain.

    A class of unified multicarrier DS-CDMA (MC DS-CDMA) schemes is defined and its performance is considered over multipath Nakagami-$M$ fading channels. The spacing between two adjacent subcarriers of the unified MC DS-CDMA scheme is a variable, allowing us to gain insight into the effects of the spacing on the bit error rate (BER) performance of MC DS-CDMA systems. This unified MC DS-CDMA scheme includes the subclasses of multitone DS-CDMA and orthogonal MC DS-CDMA as special cases. The optimu...

    Using a sample of tagged D_s decays collected near the D^*_s D_s peak production energy with the CLEO-c detector, we study the leptonic decay D^+_s to tau^+ nu_tau via the decay channel tau^+ to e^+ nu_e bar{nu}_tau. We measure B(D^+_s to tau^+ nu_tau) = (6.17 +- 0.71 +- 0.34) %. Combining with our measurements of D^+_s to mu^+ nu_mu and D^+_s to tau^+ nu_tau (via tau^+ to pi^+ bar{nu}_tau), we determine f_{D_s} = 274 +- 10 +- 5 MeV.

    Insertion mutagenesis has become one of the most popular methods for gene functions analysis.Here we report a two-element Ac/Ds transposon system containing enhancer trap and gene trap for gene tagging in rice.The excision of Ds element was examined by PCR amplification.The excision frequency of Ds element varied from 0% to 40% among 20 F2 populations derived from 11 different Ds parents.Southern blot analysis revealed that more than 70% of excised Ds elements reinserted into rice genome and above 70% of the reinserted Ds elements were located at different positions of the chromosome in rice.The result of histochemical GUS analysis indicated that 28% of enhancer trap and 22% of gene trap tagging plants displayed GUS activity in leaves, roots,flowers or seeds.The GUS positive lines will be useful for identifying gene function in rice.

  20. Calculating soil gas fluxes from gas concentration profiles: can we use standard DS models or should we use site-specific DS models?

    The apparent gas diffusion coefficient in soil (DS) is an important parameter describing soil aeration. It also links the profiles of soil gas concentration and soil gas flux using Fick's law. Soil gas diffusivity depends mainly on the structure of the pore system and the soil moisture status. There are several standard DS-models available that can easily be used for calculating DS. Another, more laborious option is to calibrate site specific DS models on soil core samples from the respective profile. We tested 4 standard DS models and a site-specific model and compared the resulting soil gas fluxes in two forest soils. Differences between the models were substantial. Another very important effect, however, is that standard DS models are usually derived from a single soil moisture measurement (device), that can result in an substantial offset in soil moisture estimation. The mean soil moisture content at a depth can be addressed more accurately by taking several soil cores. As a consequence, using standard DS models in combination with a single soil moisture measurement is less reliable than using site-specific models based on several soil samples.

    We present model-independent measurements of the branching fractions ${\\cal B}(B^0\\to D_s^{*+} D^{*-})$ and ${\\cal B}(D_s^+ \\to \\phi \\pi^+)$ based on 19.3 $\\textup{fb}^{-1}$ of data collected by the $BABAR$ detector at the PEP-II $e^+e^-$ $B$ Factory. Neutral $B$-meson decays to the $D_s^{*+}D^{*-}$ final state are selected with a partial reconstruction of the $D_s^{*+}$; that is, only the $D^{*-}$ and the soft photon from the decay $D_s^{*+} \\to \\Ds \\gamma$ are reconstructed. The branching fraction ${\\cal B}(B^0\\to D_s^{*+} D^{*-})$ is extracted from these event yields, while ${\\cal B}(D_s^+ \\to \\phi \\pi^+)$ is determined by combining this result with a previous measurement of the product ${\\cal B}(B^0\\to D_s^{*+} D^{*-}) \\times {\\cal B}(D_s^+ \\to \\phi \\pi^+)$ with partial reconstruction of the $D^{*-}$. We obtain the following preliminary results: ${\\cal B}(B^0\\to D_s^{*+} D^{*-}) = (1.50 \\pm 0.16 \\pm 0.12)%,$ ${\\cal B}(D_s^+ \\to \\phi \\pi^+) = (4.7 \\pm 0.6 \\pm 0.8)%$ where the first error is statistical, an...

    We perform a reanalysis of the energy levels obtained in a recent lattice QCD simulation, from where the existence of bound states of $KD$ and $KD^*$ are induced and identified with the narrow $D_{s0}^*(2317)$ and $D_{s1}^*(2460)$ resonances. The reanalysis is done in terms of an auxiliary potential, employing a single-channel basis $KD^{(*)}$, and a two-channel basis $KD^{(*)}, \\eta D_s^{(*)}$. By means of an extended L\\"uscher method we determine poles of the continuum t-matrix, bound by about 40 MeV with respect to the $KD$ and $KD^*$ thresholds, which we identify with the $D_{s0}^*(2317)$ and $D_{s1}^*(2460)$ resonances. Using a sum rule that generalizes Weinberg compositeness condition we can determine that the state $D_{s0}^*(2317)$ contains a $KD$ component in an amount of about 70%, while the state $D_{s1}^*(2460)$ contains a similar amount of $KD^*$. We argue that the present lattice simulation results do not still allow us to determine which are the missing channels in the bound state wave functions...

    drainage systems (SuDS). We have tested methods to reveal geological heterogeneity at field scale to identify the most suitable sites for the placement of infiltration elements and to minimize their required size. We assessed the geological heterogeneity of a clay till plain in Eastern Jutland, Denmark...... performance of SuDS can be increased considerably and oversizing avoided if field geological heterogeneity is revealed before placing SuDS....

    Using e^+e^- -> D_s^*+ D_s^- data collected near the peak D_s production energy, E_cm=4170 MeV, with the CLEO-c detector, we present the first observation of the decay D_s^+ -> proton anti-neutron. We measure a branching fraction B(D_s^+ -> p anti-n = (1.30 +- 0.36 +0.12 -0.16) x 10^-3. This is the first observation of a charmed meson decaying into a baryon-antibaryon final state.

  8. Use of Capillary Electrophoresis in the Study of Interaction between dsDNA and Drug Molecules

    2006-01-01

    Two 17-mer dsDNA with different sequence characteristics were designed to investigate the binding characteristics of berberine, an anticancer drug with uncertain binding mode, and Hoechst 33258, a model DNA minor groove binder, with dsDNA, respectively by the capillary zone electrophoresis (CZE). Kenndler model analysis revealed that Hoechst 33258 exhibited intermediate affinity with dsDNA, while there was only low affinity and some weak binding preference for AATT-containing to GGCC-containing dsDNA for berberine.

    Xiaoxue Li

    Full Text Available BACKGROUND: RNA interference (RNAi is a powerful method to inhibit gene expression in a sequence specific manner. Recently silencing the target gene through feeding has been successfully carried out in many insect species. METHODOLOGY/PRINCIPAL FINDINGS: Escherichia coli strain HT115 was genetically engineered to express dsRNA targeting genes that encode ribosomal protein Rpl19, V type ATPase D subunit, the fatty acid elongase Noa and a small GTPase Rab11. qRT-PCR showed that mRNA level of four target genes was reduced compared to ds-egfp control by feeding either engineered bacteria or dsRNAs. The maximum down-regulation of each gene varied from 35% to 100%. Tissue specific examination indicated that RNAi could be observed not only in midgut but also in other tissues like the ovary, nervous system and fat body. Silencing of rab11 through ingestion of dsRNA killed 20% of adult flies. Egg production was affected through feeding ds-noa and ds-rab11 compared to ds-egfp group. Adult flies were continuously fed with dsRNA and bacteria expressing dsRNA for 14 days and up-regulations of target genes were observed during this process. The transcripts of noa showed up-regulation compared to ds-egfp control group in four tissues on day 7 after continuous feeding either dsRNA or engineered bacteria. The maximum over-expression is 21 times compared to ds-egfp control group. Up-regulation of rab11 mRNA level could be observed in testes on day 7 after continuous bacteria treatment and in midgut on day 2 after ds-rab11 treatment. This phenomenon could also be observed in rpl19 groups. CONCLUSIONS: Our results suggested that it is feasible to silence genes by feeding dsRNA and bacteria expressing dsRNA in Bactrocera dorsalis. Additionally the over-expression of the target gene after continuously feeding dsRNA or bacteria was observed.

    2012-04-01

    The CHA(2)DS(2)-VASc score was developed to improve stroke risk stratification in atrial fibrillation (AF) patients. We sought to analyze the distribution and prognostic value of the CHA(2)DS(2)-VASc score in a cohort of ischemic stroke patients with AF. In total, 439 consecutive stroke patients with AF were studied. The CHA(2)DS(2)-VASc score was calculated according to clinical status before stroke onset. Poor outcome was defined as a modified Rankin score of 3 to 6 at 3 months. Association between CHA(2)DS(2)-VASc score and poor outcome was analyzed using logistic regression analysis. In 95.6% of patients, CHA(2)DS(2)-VASc was >1 and only 41.8% of those with previously diagnosed AF were using oral anticoagulation at the time of the stroke. Poor outcome was found in 53.1% of the patients. In univariate analysis age, female sex, current smoking, previous stroke, CHA(2)DS(2)-VASc score, and stroke severity were associated with outcome. In multivariate analysis, CHA(2)DS(2)-VASc score was independently associated with poor outcome [OR 1.36 (95% CI: 1.14-1.62), P = 0.001] as well as NIHSS [OR 1.22 (95% CI: 1.17-1.26), P DS(2)-VASc score. Independent of stroke severity, CHA(2)DS(2)-VASc score is associated with 3-month outcome. Despite all the available information and guidelines, our AF patients are clearly undertreated.

    2009-01-01

    We perform a Dalitz plot analysis of the decay Ds to K+K-pi+ with the CLEO-c data set of 586/pb of e+e- collisions accumulated at sqrt(s) = 4.17 GeV. This corresponds to about 0.57 million D_s+D_s(*)- pairs from which we select 14400 candidates with a background of roughly 15%. In contrast to previous measurements we find good agreement with our data only by including an additional f_0(1370)pi+ contribution. We measure the magnitude, phase, and fit fraction of K*(892) K+, phi(1020)pi+, K0*(1430)K+, f_0(980)pi+, f_0(1710)pi+, and f_0(1370)pi+ contributions and limit the possible contributions of other KK and Kpi resonances that could appear in this decay.

  13. Subband Adaptive Array for DS-CDMA Mobile Radio

    Directory of Open Access Journals (Sweden)

    Tran Xuan Nam

    2004-01-01

    Full Text Available We propose a novel scheme of subband adaptive array (SBAA for direct-sequence code division multiple access (DS-CDMA. The scheme exploits the spreading code and pilot signal as the reference signal to estimate the propagation channel. Moreover, instead of combining the array outputs at each output tap using a synthesis filter and then despreading them, we despread directly the array outputs at each output tap by the desired user's code to save the synthesis filter. Although its configuration is far different from that of 2D RAKEs, the proposed scheme exhibits relatively equivalent performance of 2D RAKEs while having less computation load due to utilising adaptive signal processing in subbands. Simulation programs are carried out to explore the performance of the scheme and compare its performance with that of the standard 2D RAKE.

  14. Input Parameters Optimization in Swarm DS-CDMA Multiuser Detectors

    Abrão, Taufik; Angelico, Bruno A; Jeszensky, Paul Jean E

    2010-01-01

    In this paper, the uplink direct sequence code division multiple access (DS-CDMA) multiuser detection problem (MuD) is studied into heuristic perspective, named particle swarm optimization (PSO). Regarding different system improvements for future technologies, such as high-order modulation and diversity exploitation, a complete parameter optimization procedure for the PSO applied to MuD problem is provided, which represents the major contribution of this paper. Furthermore, the performance of the PSO-MuD is briefly analyzed via Monte-Carlo simulations. Simulation results show that, after convergence, the performance reached by the PSO-MuD is much better than the conventional detector, and somewhat close to the single user bound (SuB). Rayleigh flat channel is initially considered, but the results are further extend to diversity (time and spatial) channels.

  15. A Joint Optimization Criterion for Blind DS-CDMA Detection

    Directory of Open Access Journals (Sweden)

    Sergio A. Cruces-Alvarez

    2007-01-01

    Full Text Available This paper addresses the problem of the blind detection of a desired user in an asynchronous DS-CDMA communications system with multipath propagation channels. Starting from the inverse filter criterion introduced by Tugnait and Li in 2001, we propose to tackle the problem in the context of the blind signal extraction methods for ICA. In order to improve the performance of the detector, we present a criterion based on the joint optimization of several higher-order statistics of the outputs. An algorithm that optimizes the proposed criterion is described, and its improved performance and robustness with respect to the near-far problem are corroborated through simulations. Additionally, a simulation using measurements on a real software-radio platform at 5 GHz has also been performed.

  16. The future of astronomy PhDs in France

    CERN Document Server

    Boissier, S

    2012-01-01

    This contribution presents a poll undertaken at the beginning of 2012, and addressed to every doctor in astronomy who obtained his/her degree in France. Its goal is to motivate the French astronomical community to think and discuss about what should be the training of PhDs, and what should be its objective. Further discussions and reactions can be posted e.g. on http://docastro.blogspot.fr/. A worrying results from the poll is that the majority of the participants would not encourage a young student to start a thesis in astronomy. The main reasons for this fact may be the high pressure on astronomy positions and the little interest a doctorate has for other careers in France. I suggest we either have to modify our formations or reduce the number of thesis starting each year in astronomy.

    Using a data sample of 1,475,000 $\\ZQQG$ events collected during 1994 with the L3 detector at LEP, we have studied the purely leptonic decays of heavy flavour mesons, $\\Dtau$ and $\\Btau$. A signal is observed in the invariant mass distribution $\\MDgamma$ corresponding to the decay sequence $\\Dstar \\rightarrow \\gamma {\\rm D^{-}_{s}}$, ~$\\Dtau$, ~$\\tauto \\lnunu$. The branching fraction for $\\Dtau$ decays is measured to be {$\\BR (\\Dtau) = 0.074 \\pm 0.028(stat) \\pm 0.016(syst) \\pm 0.018(norm)$}. No signal of $\\Btau$ decays is observed in the data, corresponding to an upper limit on the branching fraction $\\BR(\\Btau) < 5.7 \\times 10^{-4}$ at 90\\% CL. \\end{abstract}

  18. PRERAKE JOINT WITH STTCM FOR TDD DS-CDMA SYSTEM

    2001-01-01

    A novel synthetical transmit diversity, namely Prerake joint with Space-Time Trellis Coded Modulation (STTCM), for TDD DS-CDMA system is proposed in this paper. Space-Time Code (STC) is applied under the multipath fading circumstance. Prerake is used in stead of Rake to overcome multipath fading for the simplicity of the receiver configuration. Through computer simulation, the performance of our proposed scheme in multipath fading can be better than that of just STC is used, the taps of the Prerake should be chosen to be equal to the multipath number in the matter of minimum mean square error. A new constellation (8APK) is presented to construct a kind of STC that achieves better performance than that of 8PSK.

  19. A QCD sum rules calculation of the ηcD*D and ηc Ds* Ds form factors and strong coupling constants

    2017-10-01

    We use the QCD sum rules for the three point correlation functions to compute the strong coupling constants of the meson vertices ηcD* D and ηc Ds* Ds. We consider perturbative and non-perturbative contributions, working up to dimension five on the OPE. The vertices were studied considering that each one of its three mesons are off-shell alternately. The vertex coupling constant is evaluated through the extrapolation of the three different form factors. The results obtained for the coupling constants are gηcD*D =5.23-1.38+1.80 and g ηc Ds* Ds =5.55-1.55+1.29.

    We present measurements of the decays B0->Ds(*)+D*-, using data recorded by the BABAR detector in 1999 and 2000, consisting of 20.8 fb^-1. The analysis is conducted with a partial reconstruction technique, in which only the Ds(*)+ and the soft pion from the D*- decay are reconstructed. From the observed rates, we measure the branching fractions BR(B0->Ds+D*-) = (1.03 +- 0.14 +- 0.13 +- 0.26)% and BR(B0->Ds*+D*-) = (1.97 +- 0.15 +- 0.30 +- 0.49)%, where the first error is statistical, the second is systematic, and the third is the error due to the Ds+->phi pi+ branching fraction uncertainty. From the B0->Ds*+D*- angular distributions, we measure the fraction of longitudinal polarization Gamma_L/Gamma = (51.9 +- 5.0 +- 2.8)%, which is consistent with the theoretical prediction, based on factorization. These results are preliminary.

    The analysis of virus genome is based on nucleic acid isolation. The aims of this study were to develop a method for isolation and identification of virus double-stranded ribonucleic acid (dsRNA) and to elucidate the nucleotide sequences of strawberry virus. Using the modified method, virus dsRNA was extracted from strawberry virus indicator plants and cultivated strawberry plants and detected using agarose gel electrophoresis with ethidium bromide staining and reverse transcription-polymerase chain reaction (RT-PCR). The quantity of virus dsRNA varied among strawberry cultivars. The quantity of dsRNA from in vitro plantlets was higher than that from the young leaves of field plants. For the field-grown plants, there was more dsRNA in the young leaves. Virus dsRNA extracted from strawberry plants was resistant to deoxyribonuclease Ⅰ (DNase Ⅰ ), but evidently, it became resistant to ribonuclease A (RNase A) only in the presence of 0.5 M NaCl. Its bands in agarose gel could be readily recycled using an agarose gel DNA purification kit. With RT-PCR, the segments of both strawberry mottle virus and Strawberry mild yellow edge virus genomes were amplified by using the virus dsRNA recycled from gel or treated with DNase Ⅰ /RNase A as templates. The system developed for dsRNA isolation and identification in strawberry plants laid a sound foundation for the work on genome analysis of strawberry virus isolates in China.

    Patients with the 22q11-deletion syndrome (22q11DS) are at an increased risk of developing schizophrenia. Besides the effects of genetic variation, environmental factors could also be important in modifying the risk of schizophrenia in 22q11DS patients. In particular, previous studies have shown the

    The United States is confronting important challenges at both the early and late stages of science education. At the level of K-12 education, a recent National Research Council report (Successful K-12 STEM Education) proposed a bold restructuring of how science is taught, moving away from memorizing facts and emphasizing hands-on, inquiry-based learning and a deeper understanding of the process of science. At higher levels of training, limited funding for science is leading PhDs to seek training and careers in areas other than research. Might science PhDs play a bigger role in the future of K-12 education, particularly at the high school level? We explore this question by discussing the roles that PhDs can play in high school education and the current and rather extensive barriers to PhDs entering the teaching profession and finally suggest ways to ease the entrance of qualified PhDs into high school education.

    RNAi trigged by dsRNA not only facilitates the development of molecular biology, but also initiates a new way for pest control by silence of fatal genes. However, one of the key limitations in pest control is lack of the convenient and efifcient method for dsRNA delivery. In this study, different dsRNA delivery methods at their own optimum conditions were evaluated comparatively for their efifciency with Helicoverpa armigera as test animal. It was found that the popular one-time injection of larvae with dsRNA could reduce the pupation rate by 43.0%and enhance larva mortality by 11.7%. One-time ingestion of dsRNA did not result in any signiifcant effect on phenotype. Continuous ingestion of in vitro synthesized dsRNA by refreshing the bait diet every day caused 40.4% decrease in successful pupation and 10.0% increase in larval mortality, which was similar as one-time injection. The most efifcient method was found to be the continuous ingestion of the bacteria containing dsRNA expressed, which reduced the rate of pupation by 68.7%and enhanced the larval mortality by 34.1%. Further analysis found that dsRNA was degraded faster in midgut juice than in hemolymph. However, the cell of bacteria could protect dsRNA and delay the degradation in the midgut juice of H. armigera. These results throw light on the application of dsRNA in pest management with proper ways.

  17. Use of bacterially expressed dsRNA to downregulate Entamoeba histolytica gene expression.

    Full Text Available BACKGROUND: Modern RNA interference (RNAi methodologies using small interfering RNA (siRNA oligonucleotide duplexes or episomally synthesized hairpin RNA are valuable tools for the analysis of gene function in the protozoan parasite Entamoeba histolytica. However, these approaches still require time-consuming procedures including transfection and drug selection, or costly synthetic molecules. PRINCIPAL FINDINGS: Here we report an efficient and handy alternative for E. histolytica gene down-regulation mediated by bacterial double-stranded RNA (dsRNA targeting parasite genes. The Escherichia coli strain HT115 which is unable to degrade dsRNA, was genetically engineered to produce high quantities of long dsRNA segments targeting the genes that encode E. histolytica beta-tubulin and virulence factor KERP1. Trophozoites cultured in vitro were directly fed with dsRNA-expressing bacteria or soaked with purified dsRNA. Both dsRNA delivery methods resulted in significant reduction of protein expression. In vitro host cell-parasite assays showed that efficient downregulation of kerp1 gene expression mediated by bacterial dsRNA resulted in significant reduction of parasite adhesion and lytic capabilities, thus supporting a major role for KERP1 in the pathogenic process. Furthermore, treatment of trophozoites cultured in microtiter plates, with a repertoire of eighty-five distinct bacterial dsRNA segments targeting E. histolytica genes with unknown function, led to the identification of three genes potentially involved in the growth of the parasite. CONCLUSIONS: Our results showed that the use of bacterial dsRNA is a powerful method for the study of gene function in E. histolytica. This dsRNA delivery method is also technically suitable for the study of a large number of genes, thus opening interesting perspectives for the identification of novel drug and vaccine targets.

    In order to reduce the computational complexity of MUSIC algorithm in space searching, on the basis of the fact that the FFT's output sequence is finite, the relationship between spatial FFT's calculated value and the real value is analyzed,the concept of division of space and the concept of fuzzy boundary corresponding to calculated value are established, the method of averaging consecutive numbers is proposed for calculating the fuzzy boundary, the DS-MUSIC algorithm based on division of space is ultimately proposed. It adopts the SSS-FFT algorithm to achieve division of space and calculates the DOA's fuzzy boundary,then it searches in the limitative space with MUSIC algorithm.

    Ebola viral protein 35 (VP35), encoded by the highly pathogenic Ebola virus, facilitates host immune evasion by antagonizing antiviral signaling pathways, including those initiated by RIG-I-like receptors. Here we report the crystal structure of the Ebola VP35 interferon inhibitory domain (IID) bound to short double-stranded RNA (dsRNA), which together with in vivo results reveals how VP35-dsRNA interactions contribute to immune evasion. Conserved basic residues in VP35 IID recognize the dsRNA backbone, whereas the dsRNA blunt ends are 'end-capped' by a pocket of hydrophobic residues that mimic RIG-I-like receptor recognition of blunt-end dsRNA. Residues critical for RNA binding are also important for interferon inhibition in vivo but not for viral polymerase cofactor function of VP35. These results suggest that simultaneous recognition of dsRNA backbone and blunt ends provides a mechanism by which Ebola VP35 antagonizes host dsRNA sensors and immune responses.

  1. T4 DNA ligase is more than an effective trap of cyclized dsDNA.

    T4 DNA ligase is used in standard cyclization assays to trap double-stranded DNA (dsDNA) in low-probability, cyclic or highly bent conformations. The cyclization probability, deduced from the relative yield of cyclized product, can be used in conjunction with statistical mechanical models to extract the bending stiffness of dsDNA. By inserting the base analog 2-aminopurine (2-AP) at designated positions in 89 bp and 94 bp dsDNA fragments, we find that T4 DNA ligase can have a previously unknown effect. Specifically, we observe that addition of T4 ligase to dsDNA in proportions comparable to what is used in the cyclization assay leads to a significant increase in fluorescence from 2-AP. This effect is believed to originate from stabilization of local base-pair opening by formation of transient DNA-ligase complexes. Non-specific binding of T4 ligase to dsDNA is also confirmed using fluorescence correlation spectroscopy (FCS) experiments, which reveal a systematic reduction of dsDNA diffusivity in the presence of ligase. ATP competes with regular DNA for non-covalent binding to the T4 ligase and is found to significantly reduce DNA-ligase complexation. For short dsDNA fragments, however, the population of DNA-ligase complexes at typical ATP concentrations used in DNA cyclization studies is determined to be large enough to dominate the cyclization reaction.

    In order to increase the accuracy of blood components measurement and enhance the stability of prediction model, the quantitative signal-noise-ratio (SNR) analysis of measuring instruments based on dynamic spectrum (DS) and preprocessing method was conducted. The SNR of DS is increased after adding boxcar integrator, decreasing wavelength revolution, balancing the DS's SNR and excluding gross errors in preprocessing according to experiment results. Two volunteers were tested continuously for many times using the DS data acquiring system. The correlation coefficients of the each volunteer's DS data was increased from 0.934 and 0.953 to 0.991 and 0.987, respectively. Moreover, the gap between the correlation coefficient of the same volunteer's DS and different volunteers' DS is increased too, which shows that the SNR can be improved by these methods. The quantitative SNR analysis can guide the way of choosing preprocessing method efficiently, which will create the condition for clinical application of the blood components noninvasive measurement.

    To evaluate the efficacy of serum biomarkers such as iron, procalcitonin (PCT), C-reactive protein (CRP) and A(2)DS(2) scores at hospital admission to predict the onset and severity of stroke-associated pneumonia (SAP), 101 patients with acute stroke were selected and divided into the control and SAP group. Compared with control group, no significant differences were discovered in age, sex, vascular risk factors including hypertension, diabetes and hyperlipidemia, chronic lung disease of SAP group, while a significantly higher level was found in incidence of dysphagia, NIHSS score, A(2)DS(2) score, CURB-65 score, serum iron, serum ferritin, PCT and CRP (P DS(2) score and CURB-65 score had relatively high values in the SAP prediction (all P 0.5). When combined ferritin, PCT, and A(2)DS(2) scores and other indicators with CRP for SAP prediction, the model had a larger area under the curve (AUC) and higher specificity than individual prediction models. Spearman regression analysis presented that serum iron, serum ferritin and A(2)DS(2) score were highly correlated with CURB-65 score (P DS(2) score measured at admission were effective indicators in SAP prediction which could be used for SAP screening and severity prediction. Besides, the specificity in SAP prediction could be improved when Serum iron and A(2)DS(2) score combined with CRP.

    Large-scale automatic annotation of protein sequences remains challenging in postgenomics era. E1DS is designed for annotating enzyme sequences based on a repository of 1D signatures. The employed sequence signatures are derived using a novel pattern mining approach that discovers long motifs consisted of several sequential blocks (conserved segments). Each of the sequential blocks is considerably conserved among the protein members of an EC group. Moreover, a signature includes at least three sequential blocks that are concurrently conserved, i.e. frequently observed together in sequences. In other words, a sequence signature is consisted of residues from multiple regions of the protein sequence, which echoes the observation that an enzyme catalytic site is usually constituted of residues that are largely separated in the sequence. E1DS currently contains 5421 sequence signatures that in total cover 932 4-digital EC numbers. E1DS is evaluated based on a collection of enzymes with catalytic sites annotated in Catalytic Site Atlas. When compared to the famous pattern database PROSITE, predictions based on E1DS signatures are considered more sensitive in identifying catalytic sites and the involved residues. E1DS is available at http://e1ds.ee.ncku.edu.tw/ and a mirror site can be found at http://e1ds.csbb.ntu.edu.tw/.

    In this work, we evaluate the coupling constant and the form factors of the vertex J/ψDs using the techniques of the QCD sum rules. We consider all the three mesons off shell, resulting in three different form factors. However, despite the different form factors, when extrapolated to the pole of each off-shell meson, we find coupling constants that are in completely agreement each other. The result for the vertex J/ψDs coupling constant is gJ/ψD* sDs =4.30+0.42 -0.37GeV-1.

    ONERA's refractory DS composites were cited as materials required for use in advanced aircraft turbines, operating at high temperatures. These materials were found to be reliable in the construction of turbine blades. Requirements for a blade material in aircraft turbines operating at higher temperatures were compared with the actual performance as found in COTAC DS composite testing. The structure and properties of the more fully developed 74 and 741 types were specified. High temperature structural stability, impact of thermal and mechanical fatigue, oxidation resistance and coating capability were thoroughly evaluated. The problem of cooling passages in DS eutectic blades is also outlined.

    We report preliminary measurements of absolute hadronic branching fractions of Ds mesons determined using a double tag technique. These measurements are from 195 pb^{-1} of e+e- collisions recorded at center of mass energies near 4.17 GeV with the CLEO-c detector at CESR. We obtain absolute branching fractions for Ds+ decays to KS0 K+, K- K+ pi+, K- K+ pi+ pi-, pi+ pi+ pi-, pi+ eta, and pi+ etaprime. We discuss the problems inherent in measuring accurately the branching fraction for Ds+ to phi pi+, which is often used as a reference mode for measurement of other Ds+ branching fractions, and provide a measurement of a branching fraction that may be useful for this purpose.

    Luo, Zhongqiang; Zhu, Lidong

    2015-08-14

    In this paper, a blind adaptive detector is proposed for blind separation of user signals and blind estimation of spreading sequences in DS-CDMA systems. The blind separation scheme exploits a charrelation matrix for simple computation and effective extraction of information from observation signal samples. The system model of DS-CDMA signals is modeled as a blind separation framework. The unknown user information and spreading sequence of DS-CDMA systems can be estimated only from the sampled observation signals. Theoretical analysis and simulation results show that the improved performance of the proposed algorithm in comparison with the existing conventional algorithms used in DS-CDMA systems. Especially, the proposed scheme is suitable for when the number of observation samples is less and the signal to noise ratio (SNR) is low.

  14. Inducing RNAi in Caenorhabditis elegans by Injection of dsRNA.

    Hammell, Christopher M; Hannon, Gregory J

    2016-01-04

    In Caenorhabditis elegans, long double-stranded RNAs (dsRNAs) are overwhelmingly the trigger of choice for inducing RNA interference (RNAi). Although injection of dsRNA into the somatic or germline tissues of animals requires both specific equipment and technical skills, the ability of C. elegans to amplify the initial dsRNA trigger and to transmit the RNAi activity to other somatic tissues and to the progeny of injected animals is one of the main advantages of using C. elegans as a model system. The direct injection of dsRNA into parental animals is the most reliable method for RNAi and also presents the least experiment-to-experiment and animal-to-animal variability.

    Overexpression of EPHA2 has been observed in multiple cancers and reported to be associated with poor prognosis. Here, we produced an afucosylated humanized anti-EPHA2 monoclonal antibody (mAb), DS-8895a for cancer treatment. The antibody recognizes the extracellular juxtamembrane region of EPHA2 and therefore can bind to both full-length and truncated forms of EPHA2, which are anchored to cell membranes and recently reported to be produced by post-translational cleavage in tumors. DS-8895a exhibited markedly increased antibody dependent cellular cytotoxicity (ADCC) in vitro and also inhibited tumor growth in EPHA2-positive human breast cancer MDA-MB-231 and human gastric cancer SNU-16 xenograft mouse models. Moreover, DS-8895a in combination with cisplatin (CDDP) showed better efficacy than each of the monotherapies did in the human gastric cancer model. These results suggest that a novel antibody, DS-8895a has therapeutic potential against EPHA2-expressing tumors.

    This article presents a novel multicarrier direct sequence code-division multiple-access (MC DS-CDMA)scheme based on the loosely synchronous (LS) codes, which can achieve very high spectral efficiency. Instead of the single subcarrier modulation in a conventional MC DS-CDMA scheme,this novel scheme introduces the nonorthogonal subcarrier-group modulation, whose interferences caused by the non-orthogonal spacing in a subcarrier group can be reduced by a multicode detector. A detailed analysis for this system architecture and also a multiple-input-multiple output (MIMO) MC DS-CDMA solution to satisfy the requirement of beyond 3G mobile communication system are proposed. Simulated results demonstrate that this scheme can obtain excellent bit error rate (BER) performance, as well as achieve more than twice the spectral efficiency as that of conventional MC DS-CDMA systems.

    A novel space-time adaptive near-far robust code-synchronization array detector for asynchronous DS-CDMA systems is developed in this paper. There are the same basic requirements that are needed by the conventional matched filter of an asynchronous DS-CDMA system. For the real-time applicability, a computationally efficient architecture of the proposed detector is developed that is based on the concept of the multistage Wiener filter (MWF) of Goldstein and Reed.

    We present a method for controlled connection of gold electrodes with single dsDNA molecules (locally on a chip) by utilizing PCR. Single-stranded thiol-modified oligonucleotides are directed and immobilized to nanoscale electrodes by means of dielectrophoretic trapping, and extended in a PCR procedure finally forming a complete dsDNA bridging the gap between the electrodes. The technique opens up opportunities for detection and sensing applications, and for molecular electronics.

    Full Text Available Abstract Background Ticks are blood-sucking arthropods responsible for transmitting a wide variety of disease-causing agents, and constitute important public health threats globally. Ixodes scapularis is the primary vector of the Lyme disease agent in the eastern and central U.S. RNAi is a mechanism by which gene-specific double-stranded RNA (dsRNA triggers degradation of homologous mRNA transcripts. Here, we describe an optimized protocol for effectively suppressing gene expression in the egg and nymphal stages of I. scapularis by electroporation. Results The genes encoding the putative Phospholipase A2 (PLA2, cytoplasmic Cystatin, Syntaxin-5, β-Actin and Calreticulin were targeted by delivering the dsRNA encoding the specific gene coding regions in the unfed nymphs. Silencing was measured using real time qRT-PCR. Electroporation as a mode of dsRNA delivery appears to be substantially efficient and less traumatic to the tick than dsRNA microinjection in the unfed nymphs. Using Cy3-labeled dsRNA to monitor the movement, electroporated dsRNA entered the nymphs and spread to salivary glands and other tissues. The significant disruption of β-actin and cytoplasmic Cystatin transcripts in tick eggs demonstrate the applicability of this technique. The PLA2, cytoplasmic Cystatin, Syntaxin-5, β-Actin and Calreticulin genes were also significantly silenced, suggesting that this method has the potential to introduce dsRNA in eggs and unfed nymphs. Conclusions Our study demonstrates that electroporation can be used as a simple dsRNA delivery tool in assessing the functional role of tick genes in the vector-host interactions. This technique represents a novel approach for specific gene suppression in immature stages of ticks.

    Demoralization is a commonly observed syndrome in cancer patients, deserving to be carefully assessed in cross-cultural contexts. To examine the factor structure and concurrent and divergent validity of the Italian version of the Demoralization Scale (DS-IT) in cancer patients. The sample included 194 Italian cancer outpatients who were assessed by using the DS-IT and the Diagnostic Criteria of Psychosomatic Research-Demoralization module to examine demoralization. The Patient Health Questionnaire-9 (PHQ-9) to explore depression and the Mini-Mental Adjustment-to-Cancer-Hopelessness/Helplessness scale (Mini-MAC-HH) to explore maladaptive coping were also administered. Four factors were extracted by exploratory factor analysis on the DS-IT (disheartenment, α = .87; sense of failure, α = .77; dysphoria, α = .73; loss of meaning/purpose, α = .72; total = 0.91), accounting for 57.1% of the variance. The DS-IT factors shared between 17% and 36% of the variance. Patients reporting a diagnosis of demoralization on the Diagnostic Criteria of Psychosomatic Research-Demoralization module (23.7%) had higher scores on DS-IT loss of meaning/purpose, sense of failure, dysphoria, and DS-IT total. About half of those who were highly demoralized were not depressed and among those who had moderate or moderately severe demoralization, about 80% were not depressed on the PHQ-9. The DS-IT was significantly associated with PHQ-9 and Mini-MAC-HH. The study presents further evidence that demoralization is a significant clinical condition and that the DS-IT demonstrates satisfactory levels of validity and reliability to support its use in patients in the ambulatory cancer setting.

    Full Text Available Spread spectrum (SS is a modulation technique in which the signal occupies a bandwidth much larger than the minimum necessary to send the information. A synchronized reception with the code at the receiver is used for despreading the information before data recovery. From a long period, Walsh codes and Gold codes have been used as spread spectrum codes in Code Division Multiple Access (CDMA communications because of their ease of generation than the efficiency of these codes. Walsh codes are perfectly orthogonal binary user codes that have many popular applications in synchronous multicarrier communications although they perform poorly for asynchronous multi-user communications. Therefore, the nearly orthogonal Gold codes with their superior performance are the preferred user codes in asynchronous CDMA communications with small number of simultaneous users in the system due to their good auto-correlation (intracode correlation and cross-correlation (inter-code properties. Major drawback of these codes is that they are limited in number and in their lengths. In this paper, we performed MATLAB (7.1version algorithm to obtain the new orthogonal sets of binary space for multiuser spread-spectrum communications. We compared their performance with existing codes like Gold and Walsh code families. Our comparisons include their time domain properties like auto and cross-correlations along with bit error rate (BER performances in additive white Gaussian noise (AWGN and Rayleigh channel for the synchronous and asynchronous DS-CDMA communications. It is shown that these codes outperform the Walsh codes significantly and they match in performance with the popular nearly orthogonal Gold codes closely for asynchronous multiuser communications in AWGN noise. It is also shown that all of the binary code families considered performed comparable for Rayleigh flat-fading channels. So these new codes can be used both for asynchronous and synchronous direct sequence

    In this research, TiO2/ZrO2 nanocomposite has been prepared using sol-gel method. The TiO2/ZrO2 composite was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and transmission electron microscopy (TEM). A sensitive electrochemical biosensor is also presented for the determination of Taxol based on ds-DNA decorated multiwall carbon nanotubes-TiO2/ZrO2-chitosan-modified pencil electrode (ds-DNA-MWNTs-TiO2/ZrO2-CHIT-PGE). The UV spectroscopic data and differential pulse voltammetry revealed that there is a strong interaction between ds-DNA and Taxol. The groove binding of Taxol to ds-DNA helix has been characterized by a red shift (less than 8 nm) in wavelength and the decrease in the differential pulse voltammetry oxidation signal intensity of the Taxol at pencil graphite electrode (PGE) after its interaction with ds-DNA. Finally, a pretreated PGE modified with ds-DNA-MWNTs-TiO2/ZrO2-CHIT was tested in order to determine Taxol content in the solution. The dynamic range was from 0.7 to 1874.0 nmol L(-1) with a detection limit of 0.01 nmol L(-1). This sensing platform was successfully applied for the determination of Taxol in pharmaceutical and biological samples.

    RNA interference (RNAi) refers to the process of exogenous double-stranded RNA (dsRNA) silencing the complementary endogenous messenger RNA. RNAi has been widely used in entomological research for functional genomics in a variety of insects and its potential for RNAi-based pest control has been increasingly emphasized mainly because of its high specificity. This review focuses on the approaches of introducing dsRNA into insect cells or insect bodies to induce effective RNAi. The three most common delivery methods, namely, microinjection, ingestion, and soaking, are illustrated in details and their advantages and limitations are summarized for purpose of feasible RNAi research. In this review, we also briefly introduce the two possible dsRNA uptake machineries, other dsRNA delivery methods and the history of RNAi in entomology. Factors that influence the specificity and efficiency of RNAi such as transfection reagents, selection of dsRNA region, length, and stability of dsRNA in RNAi research are discussed for further studies.

    Previous studies have shown that pairs of closely-linked Ac/Ds transposable elements can induce various chromosomal rearrangements in plant genomes. To study chromosomal rearrangements in rice, we isolated a line (OsRLG5-161) that contains two inversely-oriented Ds insertions in OsRLG5 (Oryza sativa Receptor like kinase Gene 5). Among approximately 300 plants regenerated from OsRLG5-161 heterozygous seeds, 107 contained rearrangements including deletions, duplications and inversions of various sizes. Most rearrangements were induced by previously identified alternative transposition mechanism. Furthermore, we also detected a new class of rearrangements that contain juxtaposed inversions and deletions on the same chromosome. We propose that these novel alleles were generated by a previously unreported type of alternative transposition reactions involving the 5' and 3' termini of two inversely-oriented Ds elements located on the same chromatid. Finally, 11% of rearrangements contained inversions resulting from homologous recombination between the two inverted Ds elements in OsRLG5-161. The high frequency inheritance and great variety of rearrangements obtained suggests that the rice regeneration system results in a burst of transposition activity and a relaxation of the controls which normally limit the transposition competence of individual Ds termini. Together, these results demonstrate a greatly enlarged potential of the Ac/Ds system for plant chromosome engineering. © The Author(s) 2011. Published by Oxford University Press.

    Insertion of transposable elements (TEs) into introns can lead to their activation as alternatively spliced cassette exons, an event called exonization which can enrich the complexity of transcriptomes and proteomes. Previously, we performed the first experimental assessment of TE exonization by inserting a Ds element into each intron of the rice epsps gene. Exonization of Ds in plants was biased toward providing splice donor sites from the beginning of the inserted Ds sequence. Additionally, Ds inserted in the reverse direction resulted in a continuous splice donor consensus region by offering 4 donor sites in the same intron. The current study involved genome-wide computational analysis of Ds exonization events in the dicot Arabidopsis thaliana and the monocot Oryza sativa (rice). Up to 71% of the exonized transcripts were putative targets for the nonsense-mediated decay (NMD) pathway. The insertion patterns of Ds and the polymorphic splice donor sites increased the transcripts and subsequent protein isoforms. Protein isoforms contain protein sequence due to unspliced intron-TE region and/or a shift of the reading frame. The number of interior protein isoforms would be twice that of C-terminal isoforms, on average. TE exonization provides a promising way for functional expansion of the plant proteome.

    The positive parity scalar D$_{s0}^*$(2317) and axial-vector D$_{s1}^*$(2460) charmed strange mesons are generated by coupled-channel dynamics through the s-wave scattering of Goldstone bosons off the pseudoscalar and vector D(D$_s$)-meson ground states. The specific masses of these states are obtained as a consequence of the attraction arising from the Weinberg-Tomozawa interaction in the chiral Lagrangian. Chiral corrections to order Q$_\\chi^2$ are calculated and found to be small. The D$_{s0}^*$(2317) and D$_{s1}^*$(2460) mesons decay either strongly into the isospin-violating $\\pi^0$D$_s$ and $\\pi^0$D$_s^*$ channels or electromagnetically. We show that the $\\pi^0$-$\\eta$ and (K$^0$D$^+$-K$^+$D$^0$) mixings act constructively to generate strong widths of the order of 140 keV and emphasize the sensitivity of this value to the $KD$ component of the states. The one-loop contribution to the radiative decay amplitudes of scalar and axial-vector states is calculated using the electromagnetic Lagrangian to chiral...

  15. Does the KIR2DS5 gene protect from some human diseases?

    Directory of Open Access Journals (Sweden)

    Izabela Nowak

    Full Text Available BACKGROUND: KIR2DS5 gene encodes an activating natural killer cell receptor whose ligand is not known. It was recently reported to affect the outcome of hematopoietic stem cell transplantation. METHODOLOGY/PRINCIPAL FINDINGS: In our studies on KIR2DS5 gene associations with human diseases, we compared the frequencies of this gene in patients and relevant controls. Typing for KIR2DS5 gene was performed by either individual or multiplex polymerase chain reactions which, when compared in the same samples, gave concordant results. We noted an apparently protective effect of KIR2DS5 gene presence in several clinical conditions, but not in others. Namely, this effect was observed in ankylosing spondylitis (p=0.003, odds ratio [OR]=0.47, confidence interval [CI]=0.28-0.79, endometriosis (p=0.03, OR=0.25, CI = 0.07-0.82 and acute rejection of kidney graft (p=0.0056, OR=0.44, CI=0.24-0.80, but not in non-small-cell lung carcinoma, rheumatoid arthritis, spontaneous abortion, or leukemia (all p>0.05. In addition, the simultaneous presence of KIR2DS5 gene and HLA-C C1 allotype exhibited an even stronger protective effect on ankylosing spondylitis (p=0.0003, OR=0.35, CI=0.19-0.65, whereas a lack of KIR2DS5 and the presence of the HLA-C C2 allotype was associated with ankylosing spondylitis (p=0.0017, OR=1.92, CI=1.28-2.89, whereas a lack of KIR2DS5 and presence of C1 allotype was associated with rheumatoid arthritis (p=0.005, OR=1.47, CI=1.13-1.92. The presence of both KIR2DS5 and C1 seemed to protect from acute kidney graft rejection (p=0.017, OR=0.47, CI=0.25-0.89, whereas lack of KIR2DS5 and presence of C2 seemed to favor rejection (p=0.0015, OR=2.13, CI=1.34-3.37. CONCLUSIONS/SIGNIFICANCE: Our results suggest that KIR2DS5 may protect from endometriosis, ankylosing spondylitis, and acute rejection of kidney graft.

    The 22q11.2 deletion syndrome (22q11.2DS) is associated with the microdeletion of this chromosomal region, and represents the second most common genetic syndrome after Down's syndrome. In patients with schizophrenia, 22q11.2DS has a prevalence of 2%, and in selected groups can be increased to between 32-53%. To describe the generalities of 22q11.2DS syndrome as a genetic subtype of schizophrenia, its clinical characteristics, molecular genetic aspects, and frequency in different populations. A review was performed from 1967 to 2013 in scientific databases, compiling articles about 22q11.2DS syndrome and its association with schizophrenia. The 22q11.2 DS syndrome has a variable phenotype associated with other genetic syndromes, birth defects in many tissues and organs, and a high rate of psychiatric disorders, particularly schizophrenia. Likewise, it has been identified in clinical populations with schizophrenia selected by the presence of common syndromic characteristics. FISH, qPCR and MLPA techniques, and recently, aCGH and NGS technologies, are being used to diagnose this microdeletion. It is important in clinical practice to remember that people suffering the 22q11.2DS have a high genetic risk for developing schizophrenia, and it is considered that the simultaneous presence of this disease and 22q11.2DS represents a genetic subtype of schizophrenia. There are clear phenotypic criteria, molecular and cytogenetic methods to diagnose this group of patients, and to optimize a multidisciplinary approach in their monitoring.

    Host defense systems often rely on direct and indirect pattern recognition to sense the presence of invading pathogens. Patterns can be molecules directly produced by the pathogen or indirectly generated by changes in host parameters as a consequence of infection. Viruses are intracellular pathogens that hijack the cellular machinery to synthesize their own molecules making direct recognition of viral molecules a great challenge. Antiviral systems in prokaryotes and eukaryotes commonly exploit aberrant nucleic acid sensing to recognize virus infection as host and viral nucleic acid metabolism can greatly differ. Indeed, the generation of dsRNA is often associated with viral infection. In this review, we discuss current knowledge on the mechanisms of viral dsRNA sensing utilized by 2 important antiviral defense systems, RNA interference (RNAi) and the vertebrate immune system. The major viral sensors of the vertebrate immune systems are RIG-like receptors, while RNAi pathways depend on Dicer proteins. These 2 families of sensors share a similar helicase domain with high specificity for dsRNA, which is necessary, but not sufficient for efficient recognition by these receptors. Additional intrinsic features to the dsRNA molecule are also necessary for activation of antiviral systems. Studies utilizing synthetic ligands, in vitro biochemistry and reporter systems have greatly helped increase our knowledge on intrinsic features of dsRNA recognition. However, characteristics such as subcellular localization are extrinsic to the dsRNA itself, but certainly influence the recognition in vivo. Thus, mechanisms of viral dsRNA recognition must address how cellular sensors are recruited to nucleic acids or vice versa. Accessory proteins are likely important for in vivo recognition of extrinsic features of viral RNA, but have mostly remained undiscovered due to the limitations of previous strategies. Hence, the identification of novel components of antiviral systems must take

    Vaginally delivered microbicides are being developed to offer women self-initiated protection against transmission of sexually transmitted infections such as Chlamydia trachomatis. A small molecule, DS-96, rationally designed for high affinity to Escherichia coli lipid A, was previously demonstrated to bind and neutralize lipopolysaccharide (LPS) from a wide variety of Gram-negative bacteria (D. Sil et al., Antimicrob. Agents Chemother. 51: 2811-2819, 2007, doi:10.1128/AAC.00200-07). Aside from the lack of the repeating O antigen, chlamydial lipooligosaccharide (LOS) shares general molecular architecture features with E. coli LPS. Importantly, the portion of lipid A where the interaction with DS-96 is expected to take place is well conserved between the two organisms, leading to the hypothesis that DS-96 inhibits Chlamydia infection by binding to LOS and compromising the function. In this study, antichlamydial activity of DS-96 was examined in cell culture. DS-96 inhibited the intercellular growth of Chlamydia in a dose-dependent manner and offered a high level of inhibition at a relatively low concentration (8 μM). The data also revealed that infectious elementary bodies (EBs) were predominantly blocked at the attachment step, as indicated by the reduced number of EBs associated with the host cell surface following pretreatment. Of those EBs that were capable of attachment, the vast majority was unable to gain entry into the host cell. Inhibition of EB attachment and entry by DS-96 suggests that Chlamydia LOS is critical to these processes during the developmental cycle. Importantly, given the low association of host toxicity previously reported by Sil et al., DS-96 is expected to perform well in animal studies as an active antichlamydial compound in a vaginal microbicide.

    RNA interference has provided valuable insight into a wide range of biological systems and is a powerful tool for the analysis of gene function. The exploitation of this pathway to block the expression of specific gene targets holds considerable promise for the development of novel RNAi-based insect management strategies. In addition, there are a wide number of future potential applications of RNAi to control agricultural insect pests as well as its use for prevention of diseases in beneficial insects. The potential to synthesise large quantities of dsRNA by in-vitro transcription or in bacterial systems for RNA interference applications has generated significant demand for the development and application of high throughput analytical tools for the rapid extraction, purification and analysis of dsRNA. Here we have developed analytical methods that enable the rapid purification of dsRNA from associated impurities from bacterial cells in conjunction with downstream analyses. We have optimised TRIzol extractions in conjunction with a single step protocol to remove contaminating DNA and ssRNA, using RNase T1/DNase I digestion under high-salt conditions in combination with solid phase extraction to purify the dsRNA. In addition, we have utilised and developed IP RP HPLC for the rapid, high resolution analysis of the dsRNA. Furthermore, we have optimised base-specific cleavage of dsRNA by RNase A and developed a novel method utilising RNase T1 for RNase mass mapping approaches to further characterise the dsRNA using liquid chromatography interfaced with mass spectrometry.

  20. Developing an Informant Questionnaire for Cognitive Abilities in Down Syndrome: The Cognitive Scale for Down Syndrome (CS-DS.

    Directory of Open Access Journals (Sweden)

    Carla M Startin

    Full Text Available Down syndrome (DS is the most common genetic cause of intellectual disability (ID. Abilities relating to executive function, memory and language are particularly affected in DS, although there is a large variability across individuals. People with DS also show an increased risk of developing dementia. While assessment batteries have been developed for adults with DS to assess cognitive abilities, these batteries may not be suitable for those with more severe IDs, dementia, or visual / hearing difficulties. Here we report the development of an informant rated questionnaire, the Cognitive Scale for Down Syndrome (CS-DS, which focuses on everyday abilities relating to executive function, memory and language, and is suitable for assessing these abilities in all adults with DS regardless of cognitive ability. Complete questionnaires were collected about 128 individuals with DS. After final question selection we found high internal consistency scores across the total questionnaire and within the executive function, memory and language domains. CS-DS scores showed a wide range, with minimal floor and ceiling effects. We found high interrater (n = 55 and test retest (n = 36 intraclass correlations. CS-DS scores were significantly lower in those aged 41+ with significant cognitive decline compared to those without decline. Across all adults without cognitive decline, CS-DS scores correlated significantly to measures of general abilities. Exploratory factor analysis suggested five factors within the scale, relating to memory, self-regulation / inhibition, self-direction / initiation, communication, and focussing attention. The CS-DS therefore shows good interrater and test retest reliability, and appears to be a valid and suitable informant rating tool for assessing everyday cognitive abilities in a wide range of individuals with DS. Such a questionnaire may be a useful outcome measure for intervention studies to assess improvements to cognition, in

    Full Text Available Abstract Background Down syndrome (DS neurons are more susceptible to oxidative stress and previous studies have shown that vitamin E was able to reduce oxidative stress and improve DS neurons' viability. Therefore, this study was done to investigate the protective role of γ-tocotrienol (γT3 in DS neurons from hydrogen peroxide (H2O2 -induced oxidative stress. The pro-apoptosis tendency of γT3 was compared to α-tocopherol (αT in non-stress condition as well. Methods Primary culture of DS and euploid neurons were divided into six groups of treatment: control, H2O2, γT3 pre-treatment with H2O2, γT3 only, αT pre-treatment with H2O2 and αT only. The treatments were assessed by MTS assay and apoptosis assay by single-stranded DNA (ssDNA apoptosis ELISA assay, Hoechst and Neu-N immunofluorescence staining. The cellular uptake of γT3 and αT was determined by HPLC while protein expressions were determined by Western blot. Comparison between groups was made by the Student's t test, one-way ANOVA and Bonferroni adjustment as well as two-way ANOVA for multiple comparisons. Results One day incubation of γT3 was able to reduced apoptosis of DS neurons by 10%, however γT3 was cytotoxic at longer incubation period (14 days and at concentrations ≥ 100 μM. Pre-treatment of αT and γT3 only attenuate apoptosis and increase cell viability in H2O2-treated DS and euploid neurons by 10% in which the effects were minimal to maintain most of the DS cells' morphology. γT3 act as a free radical scavenger by reducing ROS generated by H2O2. In untreated controls, DS neurons showed lower Bcl-2/Bax ratio and p53 expression compared to normal neurons, while cPKC and PKC-δ expressions were higher in DS neurons. On the other hand, pre-treatment of γT3 in H2O2-treated DS neurons have reduced Bcl-2/Bax ratio, which was not shown in euploid neurons. This suggests that pre-treatment of γT3 did not promote DS cell survival. Meanwhile γT3 and αT treatments

    Identification and characterization of a semi-dwarfing gene ds-3 encoding a mutant DELLA protein regulating plant height through gibberellin signaling pathway. Lodging is one of the most important factors causing severe yield loss in oilseed rape. Utilization of semi-dwarf varieties has been proved the most effective way to increase lodging resistance and yield in many crops. To develop semi-dwarf germplasm in oilseed rape, we identified a semi-dwarf mutant ds-3 which showed a reduced response to phytohormones gibberellins (GAs). Genetic analysis indicated the dwarfism was controlled by a single semi-dominant gene, ds-3. The DS-3 gene was mapped to a genomic region on chromosome C07, which is syntenic to the region of a previously identified semi-dwarf gene ds-1 (BnaA06.RGA). In this region, DS-3 (BnaC07.RGA) gene was identified to encode a DELLA protein that functions as a repressor in GA signaling pathway. A substitution of proline to leucine was identified in ds-3 in the conserved VHYNP motif, which is essential for GA-dependent interaction between gibberellin receptor GID1 and DELLA proteins. Segregation analysis in the F2 population derived from the cross between ds-1 and ds-3 demonstrated that BnaA06.RGA displayed a stronger effect on plant height than BnaC07.RGA, indicating that different RGA genes may play different roles in stem elongation. In addition to BnaA06.RGA and BnaC07.RGA, two more RGA genes (BnaA09.RGA and BnaC09.RGA) were identified in the Brassica napus (B. napus) genome. Reverse-transcription polymerase chain reaction (RT-PCR) and yeast two-hybrid (Y2H) assays suggest that both BnaA09.RGA and BnaC09.RGA are transcribed in leaves and stems and can mediate GA signaling in vivo. These genes represent potential targets for screening ideal semi-dwarfing alleles for oilseed rape breeding.

    As they are not subjected to natural selection process, de novo designed proteins usually fold in a manner different from natural proteins. Recently, a de novo designed mini-protein DS119, with a βαβ motif and 36 amino acids, has folded unusually slowly in experiments, and transient dimers have been detected in the folding process. Here, by means of all-atom replica exchange molecular dynamics (REMD) simulations, several comparably stable intermediate states were observed on the folding free-energy landscape of DS119. Conventional molecular dynamics (CMD) simulations showed that when two unfolded DS119 proteins bound together, most binding sites of dimeric aggregates were located at the N-terminal segment, especially residues 5-10, which were supposed to form β-sheet with its own C-terminal segment. Furthermore, a large percentage of individual proteins in the dimeric aggregates adopted conformations similar to those in the intermediate states observed in REMD simulations. These results indicate that, during the folding process, DS119 can easily become trapped in intermediate states. Then, with diffusion, a transient dimer would be formed and stabilized with the binding interface located at N-terminals. This means that it could not quickly fold to the native structure. The complicated folding manner of DS119 implies the important influence of natural selection on protein-folding kinetics, and more improvement should be achieved in rational protein design.

    Recent high annual losses of honey bee colonies are associated with many factors, including RNA virus infections. Honey bee antiviral responses include RNA interference and immune pathway activation, but their relative roles in antiviral defense are not well understood. To better characterize the mechanism(s) of honey bee antiviral defense, bees were infected with a model virus in the presence or absence of dsRNA, a virus associated molecular pattern. Regardless of sequence specificity, dsRNA reduced virus abundance. We utilized next generation sequencing to examine transcriptional responses triggered by virus and dsRNA at three time-points post-infection. Hundreds of genes exhibited differential expression in response to co-treatment of dsRNA and virus. Virus-infected bees had greater expression of genes involved in RNAi, Toll, Imd, and JAK-STAT pathways, but the majority of differentially expressed genes are not well characterized. To confirm the virus limiting role of two genes, including the well-characterized gene, dicer, and a probable uncharacterized cyclin dependent kinase in honey bees, we utilized RNAi to reduce their expression in vivo and determined that virus abundance increased, supporting their involvement in antiviral defense. Together, these results further our understanding of honey bee antiviral defense, particularly the role of a non-sequence specific dsRNA-mediated antiviral pathway.

    The electrooxidation of double-stranded DNA (dsDNA) from calf thymus was carried by using cyclic voltammetry. A glassy carbon disk-, a platinum disk-, a platinum mesh- and a carbon vapor-deposited platinum mesh electrodes were used. It is shown that the appropriate chemical and biological (steam treatment) purification of the complete cell allows, for the graphite electrode, formation of a wide anodic dsDNA signal with two visible anodic peaks. There was no necessity of preaccumulation of dsDNA on the electrode surface and of use of mediators to get well defined voltammetric signals. These peaks apparently reflect electrooxidation of the DNA's guanine and adenine. The spectrophotometric data obtained during the electrooxidation indicate that the absorbance increases with an increase in potential and electrooxidation current of dsDNA. However, the absorption band maximum either does or does not change its position depending on the mesh material. This different spectroscopic behavior may mean that the changes in the dsDNA structure upon electrooxidation are different in the case of Pt and C electrodes.

    Adenosine-to-inosine (A-to-I) editing is a highly prevalent posttranscriptional modification of RNA, mediated by ADAR (adenosine deaminase acting on RNA) enzymes. In addition to RNA editing, additional functions have been proposed for ADAR1. To determine the specific role of RNA editing by ADAR1, we generated mice with an editing-deficient knock-in mutation (Adar1(E861A), where E861A denotes Glu(861)→Ala(861)). Adar1(E861A/E861A) embryos died at ~E13.5 (embryonic day 13.5), with activated interferon and double-stranded RNA (dsRNA)-sensing pathways. Genome-wide analysis of the in vivo substrates of ADAR1 identified clustered hyperediting within long dsRNA stem loops within 3' untranslated regions of endogenous transcripts. Finally, embryonic death and phenotypes of Adar1(E861A/E861A) were rescued by concurrent deletion of the cytosolic sensor of dsRNA, MDA5. A-to-I editing of endogenous dsRNA is the essential function of ADAR1, preventing the activation of the cytosolic dsRNA response by endogenous transcripts.

    The data presented in this article is related to the research article “RNAi of selected candidate genes interrupts growth and development of Helicoverpa armigera” (Chikate et al., 2016) [1]. RNA interference (RNAi) is emerging as a potent insect pest control strategy over current methods and their resistance by pest. In this study we tested 15 different in vitro synthesized dsRNAs for gene silencing in Helicoverpa armigera. These dsRNAs were specific against H. armigera enzymes/proteins such as proteases like trypsins (HaTry2, 3, 4 and 6), chymotrypsin (HaChy4) and cysteine proteases such as cathepsin (HaCATHL); glutathione S-transferases (HaGST1a, 6 and 8); esterases (HaAce4, HaJHE); catalase (HaCAT); super-oxide-dismutase (HaCu/ZnSOD); fatty acid binding protein (HaFabp) and chitin deacetylase (HaCda5b). These dsRNAs were fed to second instar larvae at an optimized dose (60 µg/day) for 3 days separately. Effects of dsRNA feeding were observed in terms of larval mass gain, percentage mortality and phenotypic abnormalities in later developmental stages of H. armigera. These findings might provide potential new candidates for designing sequence-specific dsRNA as pesticide in crop protection. PMID:27222861

    Closely-located transposable elements (TEs) have been known to induce chromosomal breakage and rearrangements via alternative transposition. To study genome rearrangements in rice, an Ac/Ds system has been employed. This system comprises an immobile Ac element expressed under the control of CaMV 35S promoter, and a modified Ds element. A starter line carried Ac and a single copy of Ds at the OsRLG5 (Oryza sativa receptor-like gene 5). To enhance the transpositional activity, seed-derived calli were cultured and regenerated into plants. Among 270 lines regenerated from the starter, one line was selected that contained a pair of inversely-oriented Ds elements at the OsRLG5 (Oryza sativa receptor-like gene 5). The selected line was again subjected to tissue culture to obtain a regenerant population. Among 300 regenerated plants, 107 (36 %) contained chromosomal rearrangements including deletions, duplications, and inversions of various sizes. From 34 plants, transposition mechanisms leading to such genomic rearrangements were analyzed. The rearrangements were induced by sister chromatid transposition (SCT), homologous recombination (HR), and single chromatid transposition (SLCT). Among them, 22 events (65 %) were found to be transmitted to the next generation. These results demonstrate a great potential of tissue culture regeneration and the Ac/Ds system in understanding alternative transposition mechanisms and in developing chromosome engineering in plants.

    From the perspective that the $\\Lambda_c(2595)$ and $\\Lambda_c(2625)$ are dynamically generated resonances from the $DN,~D^*N$ interaction and coupled channels, we have evaluated the rates for $\\Lambda_b \\to \\pi^- \\Lambda_c(2595)$ and $\\Lambda_b \\to \\pi^- \\Lambda_c(2625)$ up to a global unknown factor that allows us to calculate the ratio of rates and compare with experiment, where good agreement is found. Similarly, we can also make predictions for the ratio of rates of the, yet unknown, decays of $\\Lambda_b \\to D_s^- \\Lambda_c(2595)$ and $\\Lambda_b \\to D_s^- \\Lambda_c(2625)$ and make estimates for their individual branching fractions.

    Full Text Available Due to the complexity and dangerousness of drying process, the fault detection of temperature sensor is very difficult and dangerous in actual working practice and the detection effectiveness is not satisfying. For this problem, in this paper, based on the idea of information fusion and the requirements of D-S evidence method, a D-S evidence fusion structure with two layers was introduced to detect the temperature sensor fault in drying process. The first layer was data layer to establish the basic belief assignment function of evidence which could be realized by BP Neural Network. The second layer was decision layer to detect and locate the sensor fault which could be realized by D-S evidence fusion method. According to the numerical simulation results, the working conditions of sensors could be described effectively and accurately by this method, so that it could be used to detect and locate the sensor fault.

    Autoantibodies to nuclear antigens, i.e. antinuclear antibodies (ANA), antibodies to double-stranded DNA (dsDNA) and extractable nuclear antigens (ENA), are useful as diagnostic markers for a variety of autoimmune diseases. In March 2010, the Belgian national External Quality Assessment Scheme sent a questionnaire on ANA, anti-dsDNA and anti-ENA antibody testing designed by the Dutch EASI (European Autoimmunity Standardization Initiative) team, to all clinical laboratories performing ANA testing. Virtually all laboratories completed the questionnaire (97·7%, 127/130). This paper discusses the results of this questionnaire and provides valuable information on the state-of-the-art of ANA, anti-dsDNA and anti-ENA antibody testing as practiced in the Belgian laboratories. In addition, this work presents practical recommendations developed by the members of the advisory board of the scheme as a result of the outcome of this study.

    The direct sequence ultra-wideband (DS-UWB) is a promising technology for short-range wireless communications. The UWB signal is a stream of very low power density and ultra-short pulses, and the great potential of DS-UWB depends critically on the success of timing acquisition. A rapid acquisition algorithm for reducing the acquisition time of the coarse pseudo-noise (PN) sequences is proposed. The algorithm utilizes the auxiliary sequence and biscarch strategy based on the threshold comparison criterion. Both theoretical analysis and simulation tests show that with the proposed search strategy and simple operations over the symbol duration at the receiver, the proposed algorithm can considerably reduce the acquisition time even as it maintains the PN sequence acquisition probability in the DS-UWB system over the dense multipath environment.

    We analysed the process of $B^{+}_{c} \\rightarrow D^{+}_{s} \\bar{K}^{0\\ast}$ using QCD factorization (QCDF) and final-state interaction (FSI) effects. First, the $B^{+}_{c} \\rightarrow D^{+}_{s} \\bar{K}^{0\\ast}$ decay is calculated using QCDF method. The value found by using theQCDF method is less than the experimental value. Then we considered FSI effect as a sizable correction wherethe intermediate state $D^{+}^{\\ast}$ mesons via the exchange of $K^{0}(K^{0}^{\\ast}$) are produced. To consider the amplitudes ofthis intermediate state, the QCDF approach was used. The experimental branching ratio of $B^{+}_{c} \\rightarrow D^{+}_{s} \\bar{K}^{0\\ast}$ decayis less than $0.4 \\times 10^{-6}$ and our results are $(0.21 \\pm 0.04) \\times 10^{7}$ and $(0.37 \\pm 0.05) \\times 10^{6}$ from QCDF and FSI,respectively.

    Ethidium bromide (EB) is a commonly used probe for fluorescence detection and quantification of nucleic acids, since EB forms a highly luminescent complex with dsDNA. Typical detection sensitivity of EB-based assays to dsDNA in solution is about 0.1 μg. With the aim to increase the sensitivity of EB assays we have employed the Metal-Enhanced Fluorescence technology. We show that deposition of the EB/DNA complex solutions onto the silver nanoparticle surface additionally increases the far-field observable fluorescence ≈5-fold, yielding a net fluorescence enhancement factor of ≈180-fold, as compared to the free dye in solution. Subsequently, our approach enables the more sensitive detection of dsDNA.

    We report on a search for the decay B0 --> D_S+ rho- in a sample of 90 million Y(4S) decays into B meson pairs collected between 1999 and 2001 with the BaBar detector at the PEP-II asymmetric-energy e+e- collider. No significant excess of signal events above the expected background is observed. We set a 90% C.L. limit on the branching fraction Br(B0 --> D_S+ rho-) D_S+ rho- and B0 --> D+ rho-, we set a limit on the ratio of CKM-suppressed to CKM-favored amplitudes r(D rho)<9.5*10^{-3} at 90% C.L. All results are preliminary.

  2. A performance analysis of DS-CDMA and SCPC VSAT networks

    Spread-spectrum and single-channel-per-carrier (SCPC) transmission techniques work well in very small aperture terminal (VSAT) networks for multiple-access purposes while allowing the earth station antennas to remain small. Direct-sequence code-division multiple-access (DS-CDMA) is the simplest spread-spectrum technique to use in a VSAT network since a frequency synthesizer is not required for each terminal. An examination is made of the DS-CDMA and SCPC Ku-band VSAT satellite systems for low-density (64-kb/s or less) communications. A method for improving the standardf link analysis of DS-CDMA satellite-switched networks by including certain losses is developed. The performance of 50-channel full mesh and star network architectures is analyzed. The selection of operating conditions producing optimum performance is demonstrated.

    In this paper, we study thermostatistical properties of a photon gas in the framework of two deformed special relativity models defined by the cosmological coordinatizations of the de Sitter (dS) and anti-de Sitter (AdS) momentum spaces. The dS model is a doubly special relativity theory in which an ultraviolet length scale is invariant under the deformed Lorentz transformations. For the case of AdS model, however, the Lorentz symmetry breaks at the high energy regime. We show that the existence of a maximal momentum in dS momentum space leads to maximal pressure and temperature at the thermodynamical level while maximal internal energy and entropy arise for the case of the AdS momentum space due to the existence of a maximal kinematical energy. These results show the thermodynamical duality of these models much similar to their well-known kinematical duality.

    A compact dual-band bandpass filter (BPF) based on a half-mode substrate integrated waveguide (HMSIW) and double-side complementary split-ring resonators (DS-CSRR) is investigated in this paper. The proposed DS-CSRR consists of two complementary split-ring resonators (CSRRs) with different sizes. One is etched on the top surface of HMSIW, the other is on the ground. By changing the parameters of DS-CSRR, both the center frequencies and the bandwidths can be controlled independently, respectively. In order to validate its practicability, a dual-band BPF centered at 3.5 GHz/5.2 GHz is designed and demonstrated. The simulated and measured results are in good agreement with each other.

    The decay width and the mass of the D_s1(2536) have been measured via the decay channel D_s1 -> D*+K_S using 232 fb^-1 of data collected with the BABAR detector at the PEP-II asymmetric-energy e+e- storage ring. The result for the decay width is (1.03 +- 0.05 +- 0.12) MeV/c^2, with the first error denoting the statistical uncertainty and the second one the systematic uncertainty. For the mass, a value of (2534.85 +- 0.02 +- 0.40) MeV/c^2 has been obtained. The systematic error is dominated by the uncertainty on the D*+ mass. The mass difference between the D_s1 and D*+ has been measured to be (524.85 +- 0.02 +- 0.04) MeV/c^2.

    Automatic acoustic measures of voice quality in people with Down syndrome (DS) do not reliably reflect perceived voice qualities. This study used acoustic data and visual spectral data to investigate the relationship between perceived voice qualities and acoustic measures. Participants were four young adults (two males, two females; mean age 23.8 years) with DS and severe learning disabilities, at least one of whom had a hearing impairment. Participants imitated sustained /i/, /u/, and /a/ vowels at predetermined target pitches within their vocal range. Medial portions of vowels were analyzed, using Praat, for fundamental frequency, harmonics-to-noise ratio, jitter, and shimmer. Spectrograms were used to identify the presence and the duration of subharmonics at onset and offset, and mid-vowel. The presence of diplophonia was assessed by auditory evaluation. Perturbation data were highest for /a/ vowels and lowest for /u/ vowels. Intermittent productions of subharmonics were evident in spectrograms, some of which coincided with perceived diplophonia. The incidence, location, duration, and intensity of subharmonics differed between the four participants. Although the acoustic data do not clearly indicate atypical phonation, diplophonia and subharmonics reflect nonmodal phonation. The findings suggest that these may contribute to different perceived voice qualities in the study group and that these qualities may result from intermittent involvement of supraglottal structures. Further research is required to confirm the findings in the wider DS population, and to assess the relationships between voice quality, vowel type, and physiological measures.

    Double-stranded RNA (dsRNA) is an important type of RNA that plays essential roles in diverse cellular processes in eukaryotic organisms and a hallmark in infections by positive-sense RNA viruses. Currently, no in vivo technology has been developed for visualizing dsRNA in living cells. Here, we report a dsRNA binding-dependent fluorescence complementation (dRBFC) assay that can be used to efficiently monitor dsRNA distribution and dynamics in vivo. The system consists of two dsRNA-binding proteins, which are fused to the N- and C-terminal halves of the yellow fluorescent protein (YFP). Binding of the two fusion proteins to a common dsRNA brings the split YFP halves in close proximity, leading to the reconstitution of the fluorescence-competent structure and restoration of fluorescence. Using this technique, we were able to visualize the distribution and trafficking of the replicative RNA intermediates of positive-sense RNA viruses in living cells. - Highlights: • A live-cell imaging system was developed for visualizing dsRNA in vivo. • It uses dsRNA binding proteins fused with two halves of a fluorescent protein. • Binding to a common dsRNA enables the reporter to become fluorescent. • The system can efficiently monitor viral RNA replication in living cells.

    Full Text Available We investigated in Brazilian women with SLE the prevalence and levels of high avidity (HA dsDNA antibodies and tested their correlation with lupus activity and biomarkers of renal disease. We also compared these correlations to those observed with total dsDNA antibodies and antibodies against nucleosome (ANuA. Autoantibodies were detected by ELISA, while C3 and C4 levels were determined by nephelometry. Urine protein/creatinine ratio was determined, and lupus activity was measured by SLEDAI-2K. The prevalence of total and HA dsDNA antibodies was similar to but lower than that verified for ANuA. The levels of the three types of antibodies were correlated, but the correlation was more significant between HA dsDNA antibodies and ANuA. High avidity dsDNA antibodies correlated positively with ESR and SLEDAI and inversely with C3 and C4. Similar correlations were observed for ANuA levels, whereas total dsDNA antibodies only correlated with SLEDAI and C3. The levels of HA dsDNA antibodies were higher in patients with proteinuria, but their levels of total dsDNA antibodies and ANuA were unaltered. High avidity dsDNA antibodies can be found in high prevalence in Brazilian women with SLE and are important biomarkers of active disease and kidney dysfunction.

    Based on experimental flame investigations the capability of a DS {sup registered} burner to operate in a wide load range with different fuels was verified. A DS {sup registered} burner with a thermal capacity of 35 MW was installed in a combustion test facility in order to perform in-flame ash sampling and detailed measurements of temperatures, flue gas species as well as convective and radioactive heat fluxes. Moreover the DS {sup registered} burner was modified to DS {sup registered} T burner for the use of dense phase fuel conveying for indirect firing systems including the oxyfuel process. (orig.)

    2003-01-01

    Following the work of Kinnersley and Walker for flat spacetimes, we have analyzed the anti-de Sitter C-metric in a previous paper. In the de Sitter case, Podolsky and Griffiths have established that the de Sitter C-metric (dS C-metric) found by Plebanski and Demianski describes a pair of accelerated black holes in the dS background with the acceleration being provided (in addition to the cosmological constant) by a strut that pushes away the two black holes or, alternatively, by a string that pulls them. We extend their analysis mainly in four directions. First, we draw the Carter-Penrose diagrams of the massless uncharged dS C-metric, of the massive uncharged dS C-metric and of the massive charged dS C-metric. These diagrams allow us to clearly identify the presence of two dS black holes and to conclude that they cannot interact gravitationally. Second, we revisit the embedding of the dS C-metric in the 5D Minkowski spacetime and we represent the motion of the dS C-metric origin in the dS 4-hyperboloid as we...

    The purpose of this study is to examine the reliability of the clinical use of the self-built decision support system, diagnosis-supported attention deficit hyperactivity disorder (DS-ADHD), in an effort to develop the DS-ADHD system, by probing into the development of indicating patterns of past screening support systems for ADHD. The study collected data based on 107 subjects, who were divided into two groups, non-ADHD and ADHD, based on the doctor's determination, using the DSM-IV diagnostic standards. The two groups then underwent Test of Variables of Attention (TOVA) and DS-ADHD testing. The survey and testing results underwent one-way ANOVA and split-half method statistical analysis, in order to further understand whether there were any differences between the DS-ADHD and the identification tools used in today's clinical trials. The results of the study are as follows: 1) The ROC area between the TOVA and the clinical identification rate is 0.787 (95% confidence interval: 0.701-0.872); 2) The ROC area between the DS-ADHD and the clinical identification rate is 0.867 (95% confidence interval: 0.801-0.933). The study results show that DS-ADHD has the characteristics of screening for ADHD, based on its reliability and validity. It does not display any statistical differences when compared with TOVA systems that are currently on the market. However, the system is more effective and the accuracy rate is better than TOVA. It is a good tool to screen ADHD not only in Chinese children, but also in western country. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    To investigate the risk factors for post-stroke pneumonia and assess the value of A(2)DS(2) score in predicting post-stroke pneumonia in elderly stroke patients. The clinical data were retrospectively collected from elderly stroke patients from January, 2007 to December, 2012. A(2)DS(2) score was then assigned using the clinical information from the medical record. The ability of the score to discriminate between patients with post-stroke pneumonia and those without was quantified using ROC analysis. The calibration of the score was analyzed using Hosmer-Lemeshow goodness-of-fit test. A total of 131 elderly male stroke patients were enrolled in this study, among whom the incidence of post-stroke pneumonia was 29.01%. The independent risk factors for post-stroke pneumonia identified included moderate (P=0.0081, OR: 5.6089; 95%CI: 1.5663-20.0854) and severe (P=0.0048, OR: 44.4827; 95%CI: 3.1847-621.3126) neurological impairment, dysphagia (P=0.0005, OR: 7.5265; 95%CI: 2.4282-23.3292), and atrial fibrillation (P=0.0226, OR: 4.1778; 95%CI: 1.2221-14.2825). The incidence of post-stroke pneumonia ranged from 2.2% in patients with a A(2)DS(2) score less than 3 to 75% in those with a score higher than 8. The C-statistic of A(2)DS(2) score for predicting post-stroke pneumonia was 0.86 (95%CI: 0.784-0.911) by the ROC analysis. The A(2)DS(2) score was well calibrated to predict post-stroke pneumonia in elderly patients by Hosmer-Lemeshow test (7.083, P=0.528). The A(2)DS(2) score can be useful for predicting post-stroke pneumonia and for routine monitoring of high-risk elderly stroke patients in the clinical setting.

  13. Effects of ced-9 dsRNA on Caenorhabditis elegans and Meloidogyne incognita

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Problem Statement: In metazoans Programmed Cell Death (PCD is essential for proper development. Suppression of PCD is needed to guarantee cell survival and in the nematode Caenorhabditis elegans the regulation of PCD is accomplished by the function of the ced-9 gene. Approach: In this work the use of double stranded RNA (dsRNA to knock-down ced-9 gene function was tested as means to induce PCD. Results: Our results indicate that dsRNA targeting the cell death protection gene ced-9 is effective at decreasing the fecundity of C. elegans by up to 21%. The decreased fecundity correlated with an increased presence of cell corpses in developing embryos. Endogenous ced-9 transcript levels were reduced in progeny of ced-3 mutant nematodes fed bacteria expressing ced-9 dsRNA. These data suggest that nematode fecundity can be reduced by ingestion and exposure to dsRNAs targeting regulation of the cell death pathway. In an attempt to determine if plant parasitic nematodes are susceptible to the targeting of the PCD regulatory pathway we exposed Meloidogyne incognita, a plant parasitic nematode, to ced-9 dsRNA; here we show that this exposure results in decreased gall formation in the tobacco plants. Conclusion/Recommendations: Our results provide the first steps toward using RNAi technologies to attempt nematode control by targeting cell death pathways. Ongoing research with transgenic plants designed to express dsRNA for ced-9-like sequences will further test the feasibility of generating plants with RNAi-based resistance to parasitic nematodes.

    The branching fractions of D_s meson decays serve to normalize many measurements of processes involving charm quarks. Using 298 /pb of e+ e- collisions recorded at a center of mass energy of 4.17 GeV, we determine absolute branching fractions for eight D_s decays with a double tag technique. In particular we determine the branching fraction B(D_s -> K- K+ pi+) = (5.50 +- 0.23 +- 0.16)%, where the uncertainties are statistical and systematic respectively. We also provide partial branching fractions for kinematic subsets of the K- K+ pi+ decay mode.

    Full Text Available In a direct sequence/code division multiple access (DS/CDMA system, the role of the spreading sequences (codes is crucial since the multiple access interference (MAI is the main performance limitation. In this study, we propose an accurate criterion which enables the determination of the reference spreading codes which yield lower bit error rates (BER's in a given code set for a DS/CDMA system using despreading sequences weighted by stepping chip waveforms. The numerical results show that the spreading codes determined by the proposed criterion are the most suitable codes for using as references.

    This letter takes a new approach to extract a closed-form expression for the bit error rate (BER) of direct-sequence ultra wideband (DS-UWB) system. In the analysis, the main signal is impaired by multi-user interference (MUI) and an external source of interference originated by simultanously transmitting multiband orthogonal frequency division multiplexing (MB-OFDM) systems which are located in the vicinity of the DS-UWB receiver. All the transmission channels are affected by Nakagami-m fading. A Laplacian distribution is considered for MUI to comply more with real statistical behaviors of this kind of interference. © IEICE 2011.

  1. Binary De Bruijn sequences for DS-CDMA systems: analysis and results

    Directory of Open Access Journals (Sweden)

    Spinsante Susanna

    2011-01-01

    Full Text Available Abstract Code division multiple access (CDMA using direct sequence (DS spread spectrum modulation provides multiple access capability essentially thanks to the adoption of proper sequences as spreading codes. The ability of a DS-CDMA receiver to detect the desired signal relies to a great extent on the auto-correlation properties of the spreading code associated to each user; on the other hand, multi-user interference rejection depends on the cross-correlation properties of all the spreading codes in the considered set. As a consequence, the analysis of new families of spreading codes to be adopted in DS-CDMA is of great interest. This article provides results about the evaluation of specific full-length binary sequences, the De Bruijn ones, when applied as spreading codes in DS-CDMA schemes, and compares their performance to other families of spreading codes commonly used, such as m-sequences, Gold, OVSF, and Kasami sequences. While the latter sets of sequences have been specifically designed for application in multi-user communication contexts, De Bruijn sequences come from combinatorial mathematics, and have been applied in completely different scenarios. Considering the similarity of De Bruijn sequences to random sequences, we investigate the performance resulting by applying them as spreading codes. The results herein presented suggest that binary De Bruijn sequences, when properly selected, may compete with more consolidated options, and encourage further investigation activities, specifically focused on the generation of longer sequences, and the definition of correlation-based selection criteria.

  4. LED Current Balance Using a Variable Voltage Regulator with Low Dropout vDS Control

    Directory of Open Access Journals (Sweden)

    Hung-I Hsieh

    2017-02-01

    Full Text Available A cost-effective light-emitting diode (LED current balance strategy using a variable voltage regulator (VVR with low dropout vDS control is proposed. This can regulate the multiple metal-oxide-semiconductor field-effect transistors (MOSFETs of the linear current regulators (LCR, maintaining low dropout vDS on the flat vGS-characteristic curves and making all drain currents almost the same. Simple group LCRs respectively loaded with a string LED are employed to implement the theme. The voltage VVdc from a VVR is synthesized by a string LED voltage NvD, source voltage vR, and a specified low dropout vDS = VQ. The VVdc updates instantly, through the control loop of the master LCR, which means that all slave MOSFETs have almost the same biases on their flat vGS-characteristic curves. This leads to all of the string LED currents being equal to each other, producing an almost even luminance. An experimental setup with microchip control is built to verify the estimations. Experimental results show that the luminance of all of the string LEDs are almost equal to one another, with a maximum deviation below 1% during a wide dimming range, while keeping all vDS of the MOSFETs at a low dropout voltage, as expected.

  6. Decision-Making Algorithm for Multisensor Fusion Based on Grey Relation and DS Evidence Theory

    2016-01-01

    Full Text Available Decision-making algorithm, as the key technology for uncertain data fusion, is the core to obtain reasonable multisensor information fusion results. DS evidence theory is a typical and widely applicable decision-making method. However, DS evidence theory makes decisions without considering the sensors’ difference, which may lead to illogical results. In this paper, we present a novel decision-making algorithm for uncertain fusion based on grey relation and DS evidence theory. The proposed algorithm comprehensively takes consideration of sensor’s credibility and evidence’s overall discriminability, which can solve the uncertainty problems caused by inconsistence of sensors themselves and complexity of monitoring environment and simultaneously ensure the validity and accuracy of fusion results. The innovative decision-making algorithm firstly obtains the sensor’s credibility through the introduction of grey relation theory and then defines two impact factors as sensor’s credibility and evidence’s overall discriminability according to the focal element analyses and evidence’s distance analysis, respectively; after that, it uses the impact factors to modify the evidences and finally gets more reasonable and effective results through DS combination rule. Simulation results and analyses demonstrate that the proposed algorithm can overcome the trouble caused by large evidence conflict and one-vote veto, which indicates that it can improve the ability of target judgment and enhance precision of uncertain data fusion. Thus the novel decision-making method has a certain application value.

  7. Solar Deployment System (SolarDS) Model: Documentation and Sample Results

    The Solar Deployment System (SolarDS) model is a bottom-up, market penetration model that simulates the potential adoption of photovoltaics (PV) on residential and commercial rooftops in the continental United States through 2030. NREL developed SolarDS to examine the market competitiveness of PV based on regional solar resources, capital costs, electricity prices, utility rate structures, and federal and local incentives. The model uses the projected financial performance of PV systems to simulate PV adoption for building types and regions then aggregates adoption to state and national levels. The main components of SolarDS include a PV performance simulator, a PV annual revenue calculator, a PV financial performance calculator, a PV market share calculator, and a regional aggregator. The model simulates a variety of installed PV capacity for a range of user-specified input parameters. PV market penetration levels from 15 to 193 GW by 2030 were simulated in preliminary model runs. SolarDS results are primarily driven by three model assumptions: (1) future PV cost reductions, (2) the maximum PV market share assumed for systems with given financial performance, and (3) PV financing parameters and policy-driven assumptions, such as the possible future cost of carbon emissions.

  16. PKR is activated by cellular dsRNAs during mitosis and acts as a mitotic regulator.

    dsRNA-dependent protein kinase R (PKR) is a ubiquitously expressed enzyme well known for its roles in immune response. Upon binding to viral dsRNA, PKR undergoes autophosphorylation, and the phosphorylated PKR (pPKR) regulates translation and multiple signaling pathways in infected cells. Here, we found that PKR is activated in uninfected cells, specifically during mitosis, by binding to dsRNAs formed by inverted Alu repeats (IRAlus). While PKR and IRAlu-containing RNAs are segregated in the cytosol and nucleus of interphase cells, respectively, they interact during mitosis when nuclear structure is disrupted. Once phosphorylated, PKR suppresses global translation by phosphorylating the α subunit of eukaryotic initiation factor 2 (eIF2α). In addition, pPKR acts as an upstream kinase for c-Jun N-terminal kinase and regulates the levels of multiple mitotic factors such as cyclins A and B and Polo-like kinase 1 and phosphorylation of histone H3. Disruption of PKR activation via RNAi or expression of a transdominant-negative mutant leads to misregulation of the mitotic factors, delay in mitotic progression, and defects in cytokinesis. Our study unveils a novel function of PKR and endogenous dsRNAs as signaling molecules during the mitosis of uninfected cells.

    We present the tomographic cross-correlation between galaxy lensing measured in the Kilo Degree Survey (KiDS-450) with overlapping lensing measurements of the cosmic microwave background (CMB), as detected by Planck 2015. We compare our joint probe measurement to the theoretical expectation for a flat Λ cold dark matter cosmology, assuming the best-fitting cosmological parameters from the KiDS-450 cosmic shear and Planck CMB analyses. We find that our results are consistent within 1σ with the KiDS-450 cosmology, with an amplitude re-scaling parameter AKiDS = 0.86 ± 0.19. Adopting a Planck cosmology, we find our results are consistent within 2σ, with APlanck = 0.68 ± 0.15. We show that the agreement is improved in both cases when the contamination to the signal by intrinsic galaxy alignments is accounted for, increasing A by ∼0.1. This is the first tomographic analysis of the galaxy lensing - CMB lensing cross-correlation signal, and is based on five photometric redshift bins. We use this measurement as an independent validation of the multiplicative shear calibration and of the calibrated source redshift distribution at high redshifts. We find that constraints on these two quantities are strongly correlated when obtained from this technique, which should therefore not be considered as a stand-alone competitive calibration tool.

  1. Tachyon field theory description of (thermo)dynamics in dS space

    CERN Document Server

    Li, Huiquan

    2015-01-01

    In this work, we present a few pieces of evidence in support of a possible connection of the gravitational theory in dS space to the worldvolume theory of unstable D-branes. We show that the action describing the geodesic motion of a massive particle (or point-like object) in static dS space turns out to be the same as that of the tachyon field theory for an unstable particle. The motion along the radial direction from the origin, a locally Minkowski spacetime, to the horizon, a locally Rindler space times a sphere, represents just the tachyon condensation process, therefore providing a geometric picture of tachyon condensation. We further study a scalar in global or flat dS and the tachyon fluctuations in a homogeneous tachyon background, representing either the full or half S-brane, on unstable D-branes and find that certain dynamics of the dS universe corresponds to that of the homogeneous full or half S-brane. The thermal temperature of tachyon radiation is found to agree with that felt by any timelike ob...

  3. New insights into the Ds0 *(2317 ) and other charm scalar mesons

    Science.gov (United States)

    Guo, Zhi-Hui; Meißner, Ulf-G.; Yao, De-Liang

    2015-11-01

    Through the scattering of light-pseudoscalar mesons (π ,K ,η ,η' ) off charmed mesons (D ,Ds) , we study the Ds0 *(2317 ) state and other relevant charm scalar mesons in a unitarized chiral effective field theory approach. We investigate the charm scalar meson poles with different strangeness (S ) and isospin (I ) quantum numbers as well as their corresponding residues, which provide the coupling strengths of the charm scalar mesons. Both the light-quark mass and NC dependences of the pole positions of the Ds0 *(2317 ) and the poles with (S ,I )=(0 ,1 /2 ) are analyzed in detail in this work. Interestingly we observe quite similar pion mass trajectories for the resonance pole at around 2.1 GeV with (S ,I )=(0 ,1 /2 ) to those of the f0(500 ) given in the literature. When increasing the values of NC we find that a bound state and a virtual state in the (S ,I )=(1 ,0 ) channel asymmetrically approach the D K threshold for NC6 , the bound and virtual states move into the complex plane on the second Riemann sheet and become a symmetric pair of resonance poles. For large enough values of NC, neither the Ds0 *(2317 ) pole nor the poles with (S ,I )=(0 ,1 /2 ) tend to fall down to the real axis, indicating that they do not behave like a standard quark-antiquark meson at large NC.

    In a data sample of approximately 1.3 fb;{-1} collected with the D0 detector between 2002 and 2006, the orbitally excited charm state D_{s1};{+/-}(2536) has been observed with a measured mass of 2535.7+/-0.6(stat)+/-0.5(syst) MeV/c;{2} via the decay mode B_{s};{0}-->D_{s1};{-}(2536)mu;{+}nu_{mu}X. A first measurement is made of the branching ratio product Br(b[over ]-->D_{s1};{-}(2536)mu;{+}nu_{mu}X)xBr(D_{s1};{-}-->D;{*-}K_{S};{0}). Assuming that D_{s1};{-}(2536) production in semileptonic decay is entirely from B_{s};{0}, an extraction of the semileptonic branching ratio Br(B_{s};{0}-->D_{s1};{-}(2536)mu;{+}nu_{mu}X) is made.

    Introduction Defeat and entrapment are transdiagnostic constructs that play an important role in the development of depression, anxiety, suicidality and trauma-associated mental disorders. The present study aimed at presenting and validating a first German version of the Defeat-Scale (DS-d). Material and methods Through a web-based survey, N=480 participants were recruited (74% female; MAge=28.5, SDAge=11.1, Range: 18-80 years); 14.2% reported to currently suffer from a mental disorder, 8.5% reported at least one lifetime suicide attempt. All participants filled in the DS-d, the Entrapment Scale, the Rasch-based Depression Screening, the Depressive Symptoms Inventory - Suicidality Subscale, the Suicidal Behavior Questionnaire-Revised, the Childhood Trauma Screener, and the questionnaire Generalized Anxiety Disorders 2. Factorial validity was investigated through a unidimensional confirmatory factor analysis (CFA). Moreover, internal consistency, convergent validity (correlations with the other measured constructs) and criterion validity (suicidality) were examined. Results One residual correlation between 2 items that are inversely coded had to be allowed to reach a satisfying fit to the unidimensional model (RMSEA=0.077, TLI=0.94, NFI=0.93, CFI=0.95; item loadings>0.56). The DS-d-sumscore correlated highly with depression (r=0.87), Entrapment (r=0.83) and suicidality (r=0.70), and moderately with the other constructs. Participants with suicidal thoughts or behavior in the past showed higher DS-d-scores than participants without suicidality. Discussion The unidimensional structure of the English version could be confirmed in the DS-d - after allowing for a residual correlation between two inversely coded items. Correlations with the other measured constructs give support for the validity of the DS-d. Criterion validity of the instrument is supported by its relations to suicidality. It remains open whether defeat and entrapment are 2 distinct constructs. In the

  16. Status of Chiral Doublers of Heavy-Light Hadrons in Light of Recent Babar, Cleo, Belle and Selex Ds States

    Science.gov (United States)

    Nowak, Maciej A.

    We explain the main idea of the chiral doublers scenario, originating from simultaneous constraints of chiral symmetry and of heavy quark spin symmetry on effective theories of heavy-light hadrons. In particular we discuss chiral doublers for mesons, chiral doublers for excited mesons, chiral doublers for baryons and chiral doublers for excited baryons. We point out the arguments why new states Ds(2317) and Ds(2457) might be viewed as chiral doublers of Ds and Ds*. Then we comment on non-strange mesons D0(2308) and D‧1(2427) observed by Belle and Focus, and on Θc(3099) signal observed by H1. Finally, we point out that very recent discovery by SELEX of Ds(2632), if confirmed by other experiments and if spin-parity of this state is 1-, may be interpreted as a signal for chiral doubler of Ds1(2536). Such an identification implies another narrow, spin-parity 2- Ds state ca 37 MeV above the new 1-, corresponding to chiral partner of Ds2.

  3. Structural basis for the dsRNA specificity of the Lassa virus NP exonuclease.

    Directory of Open Access Journals (Sweden)

    Kathryn M Hastie

    Full Text Available Lassa virus causes hemorrhagic fever characterized by immunosuppression. The nucleoprotein of Lassa virus, termed NP, binds the viral genome. It also has an additional enzymatic activity as an exonuclease that specifically digests double-stranded RNA (dsRNA. dsRNA is a strong signal to the innate immune system of viral infection. Digestion of dsRNA by the NP exonuclease activity appears to cause suppression of innate immune signaling in the infected cell. Although the fold of the NP enzyme is conserved and the active site completely conserved with other exonucleases in its DEDDh family, NP is atypical among exonucleases in its preference for dsRNA and its strict specificity for one substrate. Here, we present the crystal structure of Lassa virus NP in complex with dsRNA. We find that unlike the exonuclease in Klenow fragment, the double-stranded nucleic acid in complex with Lassa NP remains base-paired instead of splitting, and that binding of the paired complementary strand is achieved by "relocation" of a basic loop motif from its typical exonuclease position. Further, we find that just one single glycine that contacts the substrate strand and one single tyrosine that stacks with a base of the complementary, non-substrate strand are responsible for the unique substrate specificity. This work thus provides templates for development of antiviral drugs that would be specific for viral, rather than host exonucleases of similar fold and active site, and illustrates how a very few amino acid changes confer alternate specificity and biological phenotype to an enzyme.

    By suppressing the expression of genes with essential biological functions, in planta RNAi can negatively affect the development and survival of target pests. As a part of a concerted effort to assess the risks of RNAi transgenic crops on non-target organisms, we developed an in vivo toxicity assay to examine the impacts of ingested dsRNAs incurred to the monarch butterfly, Danaus plexippus (L.), an iconic eco-indicator in North America. To create the worst case scenario, the full-length v-ATPase A cDNAs from the target pest, western corn rootworm, Diabrotica virgifera virgifera, and the non-target D. plexippus were respectively cloned. A 400 bp fragment with the highest sequence similarity between the two species was used as the template to synthesize dsRNAs for the subsequent dietary RNAi toxicity assay. Specifically, newly hatched neonates were provisioned with leaf disks surface-coated with v-ATPase A dsRNAs synthesized from D. v. virgifera and D. plexippus, respectively, a control dsRNA, β-glucoruronidase, from plants, and H2O. The endpoint measurements included gene expressions and life history traits. The 2283 bp D. plexippus v-ATPase A cDNA contains a 99 bp 5′-untranslated region, a 330 bp 3′-untranslated region, and an 1851 bp ORF encoding 617 amino acids. The temporal RNAi study did not detect any impact to D. plexippus v-ATPase A expression by the assay days and treatments. This was reflected in the phenotypic impacts of dietary RNAi, in which both survival rate and development time were not affected by the uptake of ingested dsRNAs. These combined results suggest that D. plexippus larvae are not susceptible to dietary RNAi, therefore, the impact of transgenic RNAi plants on this non-target organism is, likely, negligible.

    Patients with the 22q11-deletion syndrome (22q11DS) are at an increased risk of developing schizophrenia. Besides the effects of genetic variation, environmental factors could also be important in modifying the risk of schizophrenia in 22q11DS patients. In particular, previous studies have shown the importance of stress as a precipitating factor of psychosis. An incongruence between the perceived and actual severity of behavioral and cognitive domains could lead caregivers, and even the children themselves, to make demands that are insufficiently adapted to the child's abilities, causing stress and anxiety. Here, we investigate whether such diagnostic discrepancies are indeed present by comparing parent and teacher reports on behavioral concerns in children with 22q11DS. Behavioral questionnaires (CBCL and TRF) were prepared for both parents and teachers of 146 children with 22q11DS. We found that in line with previous reports, internalizing behavior was more frequently reported than externalizing behavior. While the behavioral profiles reported by parents and teachers were remarkably similar, the teachers' ratings were significantly lower (Total problem score p = .002). Age and IQ were not significantly associated with the severity of reported concerns. Our results indicate that indeed a disparity often exists between parents' and teachers' perceptions of the severity of a child's behavioral deficits. This may result in (substantially) different demands and expectations being placed on the child from the two fronts. We speculate that the stress resulting from this lack of cohesion between parents and teachers could precipitate, at least in some 22q11DS children, the emergence of psychosis. 2015 APA, all rights reserved

    The incidence of Acute Megakaryoblastic Leukemia (AMKL) is 500-fold higher in children with Down Syndrome (DS) compared with non-DS children, but the relevance of trisomy 21 as a specific background of AMKL in DS is still an open issue. Several Authors have determined gene expression profiles by microarray analysis in DS and/or non-DS AMKL. Due to the rarity of AMKL, these studies were typically limited to a small group of samples. We generated integrated quantitative transcriptome maps by systematic meta-analysis from any available gene expression profile dataset related to AMKL in pediatric age. This task has been accomplished using a tool recently described by us for the generation and the analysis of quantitative transcriptome maps, TRAM (Transcriptome Mapper), which allows effective integration of data obtained from different experimenters, experimental platforms and data sources. This allowed us to explore gene expression changes involved in transition from normal megakaryocytes (MK, n=19) to DS (n=43) or non-DS (n=45) AMKL blasts, including the analysis of Transient Myeloproliferative Disorder (TMD, n=20), a pre-leukemia condition. We propose a biological model of the transcriptome depicting progressive changes from MK to TMD and then to DS AMKL. The data indicate the repression of genes involved in MK differentiation, in particular the cluster on chromosome 4 including PF4 (platelet factor 4) and PPBP (pro-platelet basic protein); the gene for the mitogen-activated protein kinase MAP3K10 and the thrombopoietin receptor gene MPL. Moreover, comparing both DS and non-DS AMKL with MK, we identified three potential clinical markers of progression to AMKL: TMEM241 (transmembrane protein 241) was the most over-expressed single gene, while APOC2 (apolipoprotein C-II) and ZNF587B (zinc finger protein 587B) appear to be the most discriminant markers of progression, specifically to DS AMKL. Finally, the chromosome 21 (chr21) genes resulted to be the most over

    Individual dose estimates calculated by Dosimetry System 2002 (DS02) for the Life Span Study (LSS) of atomic bomb survivors are based on input data that specify location and shielding at the time of the bombing (ATB). A multi-year effort to improve information on survivors' locations ATB has recently been completed, along with comprehensive improvements in their terrain shielding input data and several improvements to computational algorithms used in combination with DS02 at RERF. Improvements began with a thorough review and prioritization of original questionnaire data on location and shielding that were taken from survivors or their proxies in the period 1949-1963. Related source documents varied in level of detail, from relatively simple lists to carefully-constructed technical drawings of structural and other shielding and surrounding neighborhoods. Systematic errors were reduced in this work by restoring the original precision of map coordinates that had been truncated due to limitations in early data processing equipment and by correcting distortions in the old (WWII-era) maps originally used to specify survivors' positions, among other improvements. Distortion errors were corrected by aligning the old maps and neighborhood drawings to orthophotographic mosaics of the cities that were newly constructed from pre-bombing aerial photographs. Random errors that were reduced included simple transcription errors and mistakes in identifying survivors' locations on the old maps. Terrain shielding input data that had been originally estimated for limited groups of survivors using older methods and data sources were completely re-estimated for all survivors using new digital terrain elevation data. Improvements to algorithms included a fix to an error in the DS02 code for coupling house and terrain shielding, a correction for elevation at the survivor's location in calculating angles to the horizon used for terrain shielding input, an improved method for truncating

    Natural-infected maize with strip mosaic symptoms were collected from Hangzhou,China. Double stranded RNAs were amplified using SPAT(single primer amplification technique,SPAT) and viral genomie segments were cloned.Sequence analysis revealed that three segments (1801bp 、2193bp and 3164bp,respectively )shared 98% identity, at nucleotide level, with the tenth (AF227205),the seventh (AJ297428) and the fifth (AJ409147) segments of rice blackstreaked dwarf virus (RBSDV),and their similarity were less than 88% with Maize rough dwarf fijivirus (MRDV). They showed higher homology with RBSDV than MRDV at amino acid level, too. Results for sequence homology analysis indicated that the three segments obtained from dsRNA sequencing originated from RBSDV,which is regarded as the main virus infecting maize in this area.%从杭州地区采集花叶症状的玉米,抽提双链RNA(double-stranded RNA,dsRNA).用单引物扩增方法(Single primer amplification technique,SPAT)对dsRNA进行RT-PCR扩增,获得了三条dsRNA片段的cDNA克隆并测定全序列.核苷酸水平上,三条片段(长度分别为1801 bp、2193 bp和3164 bp)分别与水稻黑条矮缩病毒(Rice black-streaked dwarf virus,RBSDV)的第十(AF227205)、第七(AJ297428)和第五(AJ409147)号片段序列存在高达98%的同源性,与玉米粗缩病毒(Maize rough dwarf fijivirus,MRDV)相应片段序列同源性最高为88%.在氨基酸水平上,推测的氨基酸序列也与RBSDV相似性较高,而与MRDV的相似性较低.序列同源性分析结果表明:三条片段来源于RBSDV.因此,该地区发生的玉米病毒病病原是水稻黑条矮缩病毒而不是玉米粗缩病毒.

    Nicotiana benthamiana is a potential host to several plant pathogens, and immature leaves of N. benthamiana are susceptible to Phytophthora infestans. In contrast, mature leaves of N. benthamiana are weakly susceptible and show basal resistance to P. infestans. We screened a gene-silenced mature plant showing high resistance to P. infestans, designated as DS2 (Disease suppression 2). The deduced amino acid sequence of cDNA responsible for DS2 encoded a putative aminoacylase. Growth of P. infestans decreased in DS2 plants. Trypan blue staining revealed inhibited hyphae growth of P. infestans with an increased number of dead cells under the penetration site in DS2 plants. Consistent with growth inhibition of P. infestans, defense responses such as reactive oxygen generation and expression of a salicylic acid-dependent PR-1a increased markedly in DS2 plants compared with that of control plants. DS2 phenotype was compromised in NahG plants, suggesting DS2 phenotype depends on the salicylic acid signaling pathway. Accelerated defense response was observed in DS2 plants elicited by INF1 elicitin as well as by NbMEK2(DD), which is the constitutive active form of NbMEK2, and act as a downstream regulator of INF1 perception. On the other hand, INF1- and NbMEK2(DD)-induced defense responses were prevented by DS2-overexpressing transgenic tobacco. These results suggest that DS2 negatively regulates plant defense responses against P. infestans via NbMEK2 and SA-dependent signaling pathway in N. benthamiana.

    Since the electrochemical oxidation peaks of both DNA and anti-tumor drug tamoxifen (TAM) overlapped with each other, the known electrochemical methods were limited in the study of the interactions between DNA and TAM. In this paper, zero current potentiometry, a new electrochemical method, was used to study the interaction of calf thymus dsDNA with TAM. The dsDNA was immobilized on the surface of carbon paste (dsDNA/CP). The dsDNA/CP connected in series between the clips of working and counter electrodes of a potentiostat and a reference electrode were immersed in aqueous solution containing TAM, the interaction of dsDNA with TAM produced a change in interfacial potential at the dsDNA/CP/solution interface. When linear sweep potential was applied to the dsDNA/CP and the corresponding I-E curve was recorded, interfacial potential offset applied potential partially, making the I-E curve displace along potential axis. Zero current potential where circuit current I was equal to zero in the I-E curve was measured to check the displacement of the I-E curve. Based on the displacement, the thermodynamic constants of the interaction between dsDNA and TAM were determined. The binding ratio of dsDNA with TAM was found to be 1:1 and the apparent binding constant was (6.85±0.20)×10(6) M(-1). As zero current potentiometry was independent of the changes in redox potential or current of both dsDNA and TAM themselves, the interaction was studied in their natural forms without damage. Moreover, TAM can be determined. The detection limit was 1.1×10(-7) M.

    New precise measurements of $D_s^+$ and $D_s^{*+}$ meson production from $B$ mesons and $q\\overline q$ continuum events near the $\\Upsilon(4S)$ resonance are presented in this paper. Using the BABAR data recorded in 1999 and 2000 of 20.8 fb$^{-1}$ on-resonance and 2.6 fb$^{-1}$ off-resonance, we measure the inclusive branching fractions ${\\cal B}(B\\to D_s^+ X) = (10.93\\pm 0.19\\pm 0.58\\pm 2.73)%$ and ${\\cal B}(B\\to D_s^{*+} X) = (7.94\\pm 0.82\\pm 0.72\\pm 1.99)%$, where the first error is statistical, the second is the systematic error, and the third is the error due to the $D_s^+\\to\\phi\\pi^+$ branching fraction uncertainty. The branching fractions $\\Sigma {\\cal B}(B\\to D_s^{(*)+} \\overline D^{(*)}) = (5.07\\pm 0.09\\pm 0.34\\pm 1.27)%$ and $\\Sigma {\\cal B}(B\\to D_s^{*+} \\overline D^{(*)}) = (4.07\\pm 0.42\\pm 0.53\\pm 1.02)%$ have been determined from the measured $D_s^{(*)+}$ momentum spectra.

    2010-07-01

    Full Text Available Abstract Background It is well documented that the translation of knowledge into clinical practice is a slow and haphazard process. This is no less true for dental healthcare than other types of healthcare. One common policy strategy to help promote knowledge translation is the production of clinical guidance, but it has been demonstrated that the simple publication of guidance is unlikely to optimise practice. Additional knowledge translation interventions have been shown to be effective, but effectiveness varies and much of this variation is unexplained. The need for researchers to move beyond single studies to develop a generalisable, theory based, knowledge translation framework has been identified. For dentistry in Scotland, the production of clinical guidance is the responsibility of the Scottish Dental Clinical Effectiveness Programme (SDCEP. TRiaDS (Translation Research in a Dental Setting is a multidisciplinary research collaboration, embedded within the SDCEP guidance development process, which aims to establish a practical evaluative framework for the translation of guidance and to conduct and evaluate a programme of integrated, multi-disciplinary research to enhance the science of knowledge translation. Methods Set in General Dental Practice the TRiaDS programmatic evaluation employs a standardised process using optimal methods and theory. For each SDCEP guidance document a diagnostic analysis is undertaken alongside the guidance development process. Information is gathered about current dental care activities. Key recommendations and their required behaviours are identified and prioritised. Stakeholder questionnaires and interviews are used to identify and elicit salient beliefs regarding potential barriers and enablers towards the key recommendations and behaviours. Where possible routinely collected data are used to measure compliance with the guidance and to inform decisions about whether a knowledge translation intervention is

    We report a measurement of the $B^0$ and $B^+$ meson decays to the $D_s^-K^0_S \\pi^+$ and $D_s^- K^+K^+$ final states, respectively, using $657 \\times 10^{6} B\\overline{B}$ pairs collected at the $\\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. Using the $D_s^-\\to \\phi\\pi^-$, $K^{*}(892)^0 K^-$ and $K^0_S K^-$ decay modes for the $D_s$ reconstruction, we measure the following branching fractions: ${\\cal B}(B^0\\to D_s^{-}K^0_S\\pi^+)=[0.47 \\pm 0.06 (\\mathrm {stat}) \\pm 0.05 (\\mathrm {syst})]\\times 10^{-4}$ and ${\\cal B}(B^+\\to D_s^-K^+K^+)= [0.93 \\pm 0.22 (\\mathrm {stat})\\pm 0.10 (\\mathrm {syst})]\\times 10^{-5}$. We find the ratio of the branching fraction of $B^+\\to D_s^-K^+K^+$ to that of the analogous Cabibbo favored $B^+\\to D_s^-K^+\\pi^+$ decay to be ${\\cal R}_{\\cal B} = 0.054 \\pm 0.013 ({\\rm stat}) \\pm 0.006 ({\\rm syst})$, which is consistent with the na\\"{\\i}ve factorization model.

    Immunomodulatory drugs (IMiDs), such as thalidomide, lenalidomide and pomalidomide, represent the basic principle of multiple myeloma treatment. However, the development of resistance is a limiting factor. Over the last years, the efficient application of cytokine-induced killer (CIK) cells has been reported as an alternative strategy to treat hematological neoplasms. In this study, we tested for a potential synergistic effect by combining the IMiDs thalidomide, lenalidomide and pomalidomide with CIK cells in different myeloma cell lines in vitro. Myeloma cells tested with CIK cells were significantly reduced. In the combination, myeloma cells were significantly reduced compared with cells only tested with IMiDs but not to the cells tested with CIK cells. Otherwise, the number of CIK cells was significantly reduced when treated with IMiDs. Because IMiDs are active in patients with myeloma, these results lead to the expectation that combination of IMiDs and CIK cells achieve better results in the treatment of multiple myeloma compared with the single use of IMiDs. Therefore, further examinations in an in vivo setting are necessary to have a closer look on the cellular interactions. Copyright © 2015 John Wiley & Sons, Ltd.

    Postoperative atrial fibrillation (POAF) is the most common arrhythmia after coronary artery bypass grafting (CABG) surgery. The identification of patients at risk for POAF would be helpful to guide prophylactic therapy. Presently, there is no simple preoperative scoring system available to predict patients at higher risk of POAF. In a retrospective observational study, we evaluated the usefulness of CHA 2 DS 2 -VASc score to predict POAF after CABG. After obtaining approval from Institutional Review Board, 729 patients undergoing CABG on cardiopulmonary bypass (CPB) were enrolled. Patients were followed in the postoperative period for POAF. A multiple regression analysis was run to predict POAF from various variables. The area under the receiver operating characteristic (ROC) curve was calculated to test discriminatory power of CHA 2 DS 2 -VASc score to predict POAF. POAF occurred in 95 (13%) patients. The patients with POAF had higher CHA 2 DS 2 -VASc scores than those without POAF (4.09 ± 0.90 vs. 2.31 ± 1.21; P DS 2 -VASc scores. The odds ratio for predicting POAF was highest with higher CHA 2 DS 2 -VASc scores (3.68). When ROC curve was calculated for the CHA 2 DS 2 -VASc scores, area of 0.87 was obtained, which was statistically significant (P DS 2 -VASc score was found useful in predicting POAF after CABG. This scoring system is simple and convenient to use in the preoperative period to alert the clinician about higher probability of POAF after CABG surgery.

    In this study, after immunization with NK cells from a KIR2DS5(+) donor and screening on cell transfectants expressing different members of the killer immunoglobulin-like receptor (KIR) family, we generated a mAb, DF200, reacting with several KIR2D receptors including KIR2DL1/L2/L3, KIR2DS1/S2 and KIR2DS5. By the analysis of peripheral blood NK cells and in vitro derived NK cell clones, we have demonstrated for the first time that KIR2DS5 is expressed at the cell surface in discrete subsets of NK cells and, after DF200 mAb-mediated engagement, can induce both cytotoxicity and cytokine release. Using co-transfection and co-immunoprecipitation, we found that KIR2DS5 associates with the DAP12 signaling polypeptide. Finally, soluble KIR2DS5-Fc fusion protein does not bind to cell transfectants expressing different HLA-C alleles, suggesting that, if KIR2DS5 does recognize HLA-C molecules, this may only occur in the presence of certain peptides.

    Caspases-3 is a kind of cysteine proteases and plays an important role in cell apoptosis. It has been reported that caspase-3 activation can be real-time detected in living cells by fluorescence resonance energy transfer (FRET) between an enhanced cyan fluorescent protein and enhanced yellow fluorescent protein. However, the large spectral overlap between cyan fluorescent protein (CFP) and yellow fluorescent protein (YFP) emission and the highly sensitivity to pH of YFP restricted their detecting sensitivity and reliability. CFP and red fluorescent protein (DsRed) possess superb wavelength separation of donor and acceptor emission spectra and DsRed was insensitive to pH, so the FRET probe composed of CFP and DsRed would be more suitable for imaging caspase-3 activation than the FRET probe composed of CFP and YFP. We constructed a vector that encoded CRS (caspase-3 recognition site) fused with CFP and DsRed (CFP-CRS-DsRed). In CFP-CRS-DsRed expressing tumor cells, FRET from CFP to DsRed could be detected. In the Clinical applications of cancer chemotherapy, cisplatin is one of the most broadly used drugs. It was already confirmed that caspase-3 was activated in HeLa cell treated by cisplatin. When the cells were stimulated with cisplatin, we found that the FRET efficient was remarkably decreased and then disappeared. It indicated that actived caspase-3 cleaved the CFP-CRS-DsRed fusion protein at CRS site. Thus, the FRET probe of CFP-CRS-DsRed could sensitively and reliably monitor caspase-3 activation in living cell. This probe will be highly useful for rapid-screening potential drugs that may target the apoptotic process and for imaging tumors in vivo.

    DS-8587 is a novel parenteral fluoroquinolone, which has an activity equivalent to sitafloxacin against various pathogens including anaerobes. We examined the in vivo anti-anaerobic activity of DS-8587, and compared it with that of levofloxacin (LVFX), using a murine model of Fusobacterium necrophorum-induced liver abscess developed via blood borne infection. Mice with liver abscess infection caused by F. necrophorum were treated with saline (control), DS-8587 (0.8, 4, and 20 mg/kg twice daily), or LVFX (20 and 100 mg/kg) for a day. After treatment, the number of viable bacteria in liver was analyzed. We also analyzed the pharmacokinetics of these agents in plasma and the liver after initial treatment. The MICs of DS-8587 and LVFX were 0.015 and 1 mg/mL, respectively. DS-8587 eradicated the viable bacteria in the liver even at doses as low as 4 mg/kg. In contrast, the liver bacteria were not eradicated in any of the LVFX-treated mice even at a dose of 100 mg/kg (P DS-8587, 4 or 20 mg/kg). The pharmacokinetic parameter AUC/MIC ratios for DS-8587 (4 mg/kg) and LVFX (100 mg/kg) were 96.7 and 60.8 in plasma and 600 and 145.6 in the liver, respectively. The AUC/MIC ratio showed the best correlation with efficacy of DS-8587. DS-8587 significantly reduced the number of viable bacteria in a murine model of F. necrophorum-induced liver abscess compared to LVFX. Our study demonstrated that the anti-anaerobic activity of quinolones in vivo was different from the MICs in vitro.

  5. Revolution rather than rotation of AAA+ hexameric phi29 nanomotor for viral dsDNA packaging without coiling☆

    It has long been believed that the DNA-packaging motor of dsDNA viruses utilizes a rotation mechanism. Here we report a revolution rather than rotation mechanism for the bacteriophage phi29 DNA packaging motor. The phi29 motor contains six copies of the ATPase (Schwartz et al., this issue); ATP binding to one ATPase subunit stimulates the ATPase to adopt a conformation with a high affinity for dsDNA. ATP hydrolysis induces a new conformation with a lower affinity, thus transferring the dsDNA to an adjacent subunit by a power stroke. DNA revolves unidirectionally along the hexameric channel wall of the ATPase, but neither the dsDNA nor the ATPase itself rotates along its own axis. One ATP is hydrolyzed in each transitional step, and six ATPs are consumed for one helical turn of 360°. Transition of the same dsDNA chain along the channel wall, but at a location 60° different from the last contact, urges dsDNA to move forward 1.75 base pairs each step (10.5 bp per turn/6ATP=1.75 bp per ATP). Each connector subunit tilts with a left-handed orientation at a 30° angle in relation to its vertical axis that runs anti-parallel to the right-handed dsDNA helix, facilitating the one-way traffic of dsDNA. The connector channel has been shown to cause four steps of transition due to four positively charged lysine rings that make direct contact with the negatively charged DNA phosphate backbone. Translocation of dsDNA into the procapsid by revolution avoids the difficulties during rotation that are associated with DNA supercoiling. Since the revolution mechanism can apply to any stoichiometry, this motor mechanism might reconcile the stoichiometry discrepancy in many phage systems where the ATPase has been found as a tetramer, hexamer, or nonamer.

    The interaction between two single-stranded DNA (ssDNA) molecules as pairing to a double-stranded DNA (dsDNA) molecule is studied by the reflectometric interference spectroscopy (RIFS) technology.A nano-porous anode alumina membrane coated an Au layer is employed as the sensor substrate.The results indicate that when there are mismatched nucleotide bases,the effective optical thicknesses (OTeff) have obvious difference,and the changes of OTeff are connected with the sensor layer thickness and the effective refractive index.It is also demonstrated that the RIFS technique can be used to precisely detect the ssDNA molecules with individual base mismatched as pairing to dsDNA.

    We observe the decays Ds1*(2710)+→D*K and DsJ*(2860)+→D*K and measure their branching fractions relative to the DK final state. We also observe, in the D*K mass spectrum, a new broad structure at a mass of (3044±8stat((+30)/(-5))syst)MeV/c2 having a width Γ=(239±35stat((+46)/(-42))syst)MeV. To obtain this result we use 470fb-1 of data recorded by the BABAR detector at the PEP-II asymmetric-energy e+e- storage rings at the Stanford Linear Accelerator Center running at center-of-mass energies near 10.6 GeV.

  8. Non-Specific dsRNA-Mediated Antiviral Response in the Honey Bee

    2013-01-01

    Honey bees are essential pollinators of numerous agricultural crops. Since 2006, honey bee populations have suffered considerable annual losses that are partially attributed to Colony Collapse Disorder (CCD). CCD is an unexplained phenomenon that correlates with elevated incidence of pathogens, including RNA viruses. Honey bees are eusocial insects that live in colonies of genetically related individuals that work in concert to gather and store nutrients. Their social organization provides numerous benefits, but also facilitates pathogen transmission between individuals. To investigate honey bee antiviral defense mechanisms, we developed an RNA virus infection model and discovered that administration of dsRNA, regardless of sequence, reduced virus infection. Our results suggest that dsRNA, a viral pathogen associated molecular pattern (PAMP), triggers an antiviral response that controls virus infection in honey bees. PMID:24130869

    The ground state properties of Ds (Z=110) isotopes (N=151-195) are studied in the framework of the relativistic mean field (RMF) theory with the effective interaction NL-Z2.The pairing correlation is treated within the conventional BCS approximation.The calculated binding energies are consistent with the results from finite-range droplet model (FRDM) and Macroscopic-microscopic method (MMM).The quadrupole deformation,α-decay energy,α-decay half-live,charge radius,two-neutron separation energy and single-particle spectra are analyzed for Ds isotopes to find new characteristics of superheavy nuclei (SHN).Among the calculated results it is rather distinct that the isotopic shift appears evidently at neutron number N=184.

    DNA is increasingly used as a material in the design and construction of elaborate structures with nanoscale precision and functionalities. Whether self-assembled from tiles of short, synthetic oligomers or woven from purified genomic strands, most DNA nanostructures are based on parallel arrays of double-stranded DNA (dsDNA) held together by Holliday junction-like cross-links. There is considerable evidence that the double-helices thus intertwined are largely B-form in structure, but the mechanical integrity of the resulting nanostructures has gone largely unexplored. Here we present a systematic study of the stiffness of DNA nanotubes varying parameters such as helix number, cross-link density and strand complexity. We find stiffness is a useful reporter of structural quality for nanotubes and extract design principles for optimizing mechanical integrity of dsDNA materials.

Several reaction parameters afJecting the succinylation were investigated including the concentration of starch in water, the ratio of succinic anhydride to starch, the reaction time and the reaction temperature. The favorable conditions for an intermediate degree of substitution (DS) and reasonably high reaction efficiency (RE) are pH 8.5~9.0, 50% starch by weight to water, succinic anhydride to starch I/I (w/w), reaction time 4h, reaction temperature 30 ℃Under these conditions, the DS of 0.45 and RE of 28% were achieved. The addition of an adequate amount of crosslinking agent imparted starch succinate water absorbency.

    Full Text Available We investigate the performance of turbo interference cancellation receivers in the space time block coded (STBC direct-sequence code division multiple access (DS-CDMA system. Depending on the concatenation scheme used, we divide these receivers into the partitioned approach (PA and the iterative approach (IA receivers. The performance of both the PA and IA receivers is evaluated in Rayleigh fading channels for the uplink scenario. Numerical results show that the MMSE front-end turbo space-time iterative approach receiver (IA effectively combats the mixture of MAI and intersymbol interference (ISI. To further investigate the possible achievable data rates in the turbo interference cancellation receivers, we introduce the puncturing of the turbo code through the use of rate compatible punctured turbo codes (RCPTCs. Simulation results suggest that combining interference cancellation, turbo decoding, STBC, and RCPTC can significantly improve the achievable data rates for a synchronous DS-CDMA system for the uplink in Rayleigh flat fading channels.

    In this paper, we describe direct-sequence code-division multiple-access (DS-CDMA) systems with quadriphase-shift keying in which channel estimation, coherent demodulation, and decoding are iteratively performed without the use of any training or pilot symbols. An expectation-maximization channel-estimation algorithm for the fading amplitude, phase, and the interference power spectral density (PSD) due to the combined interference and thermal noise is proposed for DS-CDMA systems with irregular repeat-accumulate codes. After initial estimates of the fading amplitude, phase, and interference PSD are obtained from the received symbols, subsequent values of these parameters are iteratively updated by using the soft feedback from the channel decoder. The updated estimates are combined with the received symbols and iteratively passed to the decoder. The elimination of pilot symbols simplifies the system design and allows either an enhanced information throughput, an improved bit error rate, or greater spectral eff...

  15. Non-specific dsRNA-mediated antiviral response in the honey bee.

    Directory of Open Access Journals (Sweden)

    Michelle L Flenniken

    Full Text Available Honey bees are essential pollinators of numerous agricultural crops. Since 2006, honey bee populations have suffered considerable annual losses that are partially attributed to Colony Collapse Disorder (CCD. CCD is an unexplained phenomenon that correlates with elevated incidence of pathogens, including RNA viruses. Honey bees are eusocial insects that live in colonies of genetically related individuals that work in concert to gather and store nutrients. Their social organization provides numerous benefits, but also facilitates pathogen transmission between individuals. To investigate honey bee antiviral defense mechanisms, we developed an RNA virus infection model and discovered that administration of dsRNA, regardless of sequence, reduced virus infection. Our results suggest that dsRNA, a viral pathogen associated molecular pattern (PAMP, triggers an antiviral response that controls virus infection in honey bees.

    Summary We show that DNA methyltransferase inhibitors (DNMTis) upregulate immune signaling in cancer through the viral defense pathway. In ovarian cancer (OC), DNMTis trigger cytosolic sensing of double-stranded RNA (dsRNA) causing a Type I Interferon response and apoptosis. Knocking down dsRNA sensors TLR3 and MAVS reduces this response twofold, and blocking interferon beta or its receptor abrogates it. Upregulation of hypermethylated endogenous retrovirus (ERV) genes accompanies the response and ERV overexpression activates the response. Basal levels of ERV and viral defense gene expression significantly correlate in primary OC and the latter signature separates primary samples for multiple tumor types from The Cancer Genome Atlas into low versus high expression groups. In melanoma patients treated with an immune checkpoint therapy, high viral defense signature expression in tumors significantly associates with durable clinical response and DNMTi treatment sensitizes to anti-CTLA4 therapy in a pre-clinical melanoma model.

  17. Simulations of Micro Gas Flows by the DS-BGK Method

    KAUST Repository

    Li, Jun

    2011-01-01

    For gas flows in micro devices, the molecular mean free path is of the same order as the characteristic scale making the Navier-Stokes equation invalid. Recently, some micro gas flows are simulated by the DS-BGK method, which is convergent to the BGK equation and very efficient for low-velocity cases. As the molecular reflection on the boundary is the dominant effect compared to the intermolecular collisions in micro gas flows, the more realistic boundary condition, namely the CLL reflection model, is employed in the DS-BGK simulation and the influence of the accommodation coefficients used in the molecular reflection model on the results are discussed. The simulation results are verified by comparison with those of the DSMC method as criteria. Copyright © 2011 by ASME.

    Astronomical images can be efficiently compressed by the multi-resolution package MR1. We describe here a user interface for the images compressed by the software package MR/1 which comes as a plug-in for the popular astronomical image viewer SAO-DS9. This interface allows the user to load a compressed file and to choose not only the scale, but also the size and the portion of image to be displayed, resulting in reduced memory and processing requirements. Astrometry and all SAO-DS9 functionalities are still available. The Tcl/Tk source code of the interface, and the binary code for the decompression (for Unix and Windows) will be made available to the astronomical community.

    Reduced accommodation is seen in children and young adults with Down syndrome (DS), yet providing bifocals has not become a routine clinical management. This study investigates the impact of bifocals on visual function, visual perceptual and early literacy skills in a group of school children with DS.   In this longitudinal study, each child was followed for 5months with single-vision (SV) lenses after which bifocals were prescribed if required, based on their accommodative response. Visual acuity (VA), accommodation, perceptual and literacy skills were measured after adaptation to bifocals and 5months later. Educational progress and compliance with spectacle wear were assessed through school and parental reports.   Fourteen children and young adults with DS participated in the study. Eighty-five percent required bifocals with additions ranging from +1.00D to +3.50D. The mean near logMAR VA improved with bifocals (p=0.007) compared to SV lenses. Repeated measures anova showed that there was more accurate focus (less accommodative lag) through the bifocals (p=0.002), but no change in the accommodation exerted through the distance portion compared to SV lenses (p=0.423). There was a main effect of time on sight words (p=0.013), Word Identification (p=0.047), Visual Closure (p=0.006) and Visual Form Constancy (p=0.001). Bifocals provide clearer near vision in DS children with reduced accommodation. This is shown by improved VA and decreased lag of accommodation. The results indicate that the improvement in VA results in improved scores in early literacy skills. Better compliance with bifocals over SV lenses was seen. © 2010 The Authors.

    DNA-protein interactions, including DNA-antibody complexes, have both fundamental and practical significance. In particular, antibodies against double-stranded DNA play an important role in the pathogenesis of autoimmune diseases. Elucidation of structural mechanisms of an antigen recognition and interaction of anti-DNA antibodies provides a basis for understanding the role of DNA-containing immune complexes in human pathologies and for new treatments. Here we used Molecular Dynamic simulations of bimolecular complexes of a segment of dsDNA with a monoclonal anti-DNA antibody's Fab-fragment to obtain detailed structural and physical characteristics of the dynamic intermolecular interactions. Using a computationally modified crystal structure of a Fab-DNA complex (PDB: 3VW3), we studied in silico equilibrium Molecular Dynamics of the Fab-fragment associated with two homologous dsDNA fragments, containing or not containing dimerized thymine, a product of DNA photodamage. The Fab-fragment interactions with the thymine dimer-containing DNA was thermodynamically more stable than with the native DNA. The amino acid residues constituting a paratope and the complementary nucleotide epitopes for both Fab-DNA constructs were identified. Stacking and electrostatic interactions were shown to play the main role in the antibody-dsDNA contacts, while hydrogen bonds were less significant. The aggregate of data show that the chemically modified dsDNA (containing a covalent thymine dimer) has a higher affinity toward the antibody and forms a stronger immune complex. These findings provide a mechanistic insight into formation and properties of the pathogenic anti-DNA antibodies in autoimmune diseases, such as systemic lupus erythematosus, associated with skin photosensibilization and DNA photodamage.

    Glut1 deficiency syndrome (Glut1-DS) is a neurological and metabolic disorder caused by impaired transport of glucose across the blood brain barrier (BBB). Mutations on the SCL2A1 gene encoding the glucose transporter protein in the BBB cause the syndrome, which encompasses epilepsy, movement disorders, and mental delay. Such variability of symptoms presents an obstacle to early diagnosis. The patients seem to share some craniofacial features, and identification and quantification of these could help in prompt diagnosis and clinical management. We performed a three-dimensional morphometric analysis of the faces of 11 female Glut1-DS patients using a stereophotogrammetric system. Data were analyzed using both inter-landmark distances and Principal Component Analysis. Compared with data collected from age-, sex-, and ethnicity-matched control subjects, common and homogenous facial features were identified among patients, which were mainly located in the mandible and the eyes. Glut1-DS patients had a more anterior chin; their mandibular body was longer but the rami were shorter, with a reduced gonial angle; they had smaller and down-slanted eyes with a reduced intercanthal distance. This study highlights the importance of morphometric analysis for defining the facial anatomical characteristics of the syndrome better, potentially helping clinicians to diagnose Glut1-DS. Improved knowledge of the facial anatomy of these patients can provide insights into their facial and cerebral embryological development, perhaps further clarifying the molecular basis of the syndrome.

    Conventional D-S evidence theory has an unavoidable disadvantage in that it will give counter-intuitive result when fusing high conflict information. This paper proposes an improved method to solve this problem. By reassigning weight factors before fusing, the method can give reasonable results especially when the initial weight factors of conflict evidences are almost equal. It gives an adjustable factor to adjust the reassigning force. An example is given to illustrate these advantages

    RNA interference-mediated gene silencing was shown to be an efficient tool for validation of targets that may become anti-tick vaccine components. Here, we demonstrate the application of this approach in the validation of components of molecular signaling cascades, such as the Protein Kinase B (AKT) / Glycogen Synthase Kinase (GSK) axis during tick embryogenesis. It was shown that heptane and hypochlorite treatment of tick eggs can remove wax, affecting corium integrity and but not embryo development. Evidence of AKT and GSK dsRNA delivery into de-waxed eggs of via electroporation is provided. Primers designed to amplify part of the dsRNA delivered into the electroporated eggs dsRNA confirmed its entry in eggs. In addition, it was shown that electroporation is able to deliver the fluorescent stain, 4',6-diamidino-2-phenylindole (DAPI). To confirm gene silencing, a second set of primers was designed outside the dsRNA sequence of target gene. In this assay, the suppression of AKT and GSK transcripts (approximately 50% reduction in both genes) was demonstrated in 7-day-old eggs. Interestingly, silencing of GSK in 7-day-old eggs caused 25% reduction in hatching. Additionally, the effect of silencing AKT and GSK on embryo energy metabolism was evaluated. As expected, knockdown of AKT, which down regulates GSK, the suppressor of glycogen synthesis, decreased glycogen content in electroporated eggs. These data demonstrate that electroporation of de-waxed R. microplus eggs could be used for gene silencing in tick embryos, and improve the knowledge about arthropod embryogenesis. PMID:26091260

    Full Text Available A differential space-time block code (DSTBC modulation scheme is used to improve the performance of DS-CDMA systems in fast time-dispersive fading channels. The resulting scheme is referred to as the differential space-time block code modulation for DS-CDMA (DSTBC-CDMA systems. The new modulation and demodulation schemes are especially studied for the down-link transmission of DS-CDMA systems. We present three demodulation schemes, referred to as the differential space-time block code Rake (D-Rake receiver, differential space-time block code deterministic (D-Det receiver, and differential space-time block code deterministic de-prefix (D-Det-DP receiver, respectively. The D-Det receiver exploits the known information of the spreading sequences and their delayed paths deterministically besides the Rake type combination; consequently, it can outperform the D-Rake receiver, which employs the Rake type combination only. The D-Det-DP receiver avoids the effect of intersymbol interference and hence can offer better performance than the D-Det receiver.

    Through the scattering of light-pseudoscalar mesons ($\\pi,K,\\eta,\\eta'$) off charmed mesons ($D, D_s$), we study the $D^{*}_{s0}(2317)$ state and other relevant charm scalar mesons in a unitarized chiral effective field theory approach. We investigate the charm scalar meson poles with different strangeness ($S$) and isospin ($I$) quantum numbers as well as their corresponding residues, which provide the coupling strengths of the charm scalar mesons. Both the light-quark mass and $N_C$ dependences of the pole positions of the $D^{*}_{s0}(2317)$ and the poles with $(S,I)=(0,1/2)$ are analyzed in detail in this work. Interestingly we observe quite similar pion mass trajectories for the resonance pole at around 2.1 GeV with $(S,I)=(0,1/2)$ to those of the $f_0(500)$ given in the literature. When increasing the values of $N_C$ we find that a bound state and a virtual state in the $(S,I)=(1,0)$ channel asymmetrically approach the $D K$ threshold for $N_C6$, the bound and virtual states move into the complex plane o...

    Transposons are effective mutagens alternative to T-DNA for the generation of insertional mutants in many plant species including those whose transformation is inefficient. The current strategies of transposon tagging are usually slow and labor-intensive and yield low frequency of tagged lines. We have constructed a series of transposon tagging vectors based on three approaches: (ⅰ) AcTPase controlled by glucocorticoid binding domainNP16 acidic activation domain/Gal4 DNA-binding domain (GVG) chemical-inducible expression system; (ⅱ) deletion of AcTPase via Cre-lox site-specific recombination that was initially triggered by Ds excision; and (ⅲ) suppression of early transposition events in transformed rice callus through a dual.functional hygromycin resistance gene in a novel Ds element (HPT-Ds). We tested these vectors in transgenic rice and characterized the transposition events. Our results showed that these vectors are useful resources for functional genomics of rice and other crop plants. The vectors are freely available for the community.

    In recent years there has been great interest in using hybrid spread-spectrum (HSS) techniques for commercial applications, particularly in the Smart Grid, in addition to their inherent uses in military communications. This is because HSS can accommodate high data rates with high link integrity, even in the presence of significant multipath effects and interfering signals. A highly useful form of this transmission technique for many types of command, control, and sensing applications is the specific code-related combination of standard direct-sequence modulation with "fast" frequency-hopping, denoted hybrid DS/FFH, wherein multiple frequency hops occur within a single data-bit time. In this paper, we present the efforts carried out at Oak Ridge National Laboratory toward exploring the design, implementation, and evaluation of a hybrid DS/FFH spread-spectrum radio transceiver using a single Field Programmable Gate Array (FPGA). The FPGA allows the various subsystems to quickly communicate with each other and thereby maintain tight synchronization. We also investigate various hopping sequences against robustness to interference and jamming. Experimental results are presented that show the receiver sensitivity, radio data-rate/bit-error evaluations, and jamming and interference rejection capabilities of the implemented hybrid DS/FFH spread-spectrum system under widely varying design parameters.

    RNA interference (RNAi) is a crucial antiviral defense mechanism in insects, including the major mosquito species that transmit important human viruses. To counteract the potent antiviral RNAi pathway, insect viruses encode RNAi suppressors. However, whether mosquito-specific viruses suppress RNAi remains unclear. We therefore set out to study RNAi suppression by Culex Y virus (CYV), a mosquito-specific virus of the Birnaviridae family that was recently isolated from Culex pipiens mosquitoes. We found that the Culex RNAi machinery processes CYV double-stranded RNA (dsRNA) into viral small interfering RNAs (vsiRNAs). Furthermore, we show that RNAi is suppressed in CYV-infected cells and that the viral VP3 protein is responsible for RNAi antagonism. We demonstrate that VP3 can functionally replace B2, the well-characterized RNAi suppressor of Flock House virus. VP3 was found to bind long dsRNA as well as siRNAs and interfered with Dicer-2-mediated cleavage of long dsRNA into siRNAs. Slicing of target RNAs by pre-assembled RNA-induced silencing complexes was not affected by VP3. Finally, we show that the RNAi-suppressive activity of VP3 is conserved in Drosophila X virus, a birnavirus that persistently infects Drosophila cell cultures. Together, our data indicate that mosquito-specific viruses may encode RNAi antagonists to suppress antiviral RNAi.

    Multiple packets reception (MPR) is a new method to improve the network performance. If a node in the network has the capability of MPR, the node can receive multiple packets simultaneously, not to discard all the packets like the traditional method. In this paper, Bit error rate (BER) for direct-sequence spread spectrum multiple access system over Rice fading channel is considered, based on the standard Gaussian approximation, and the explicit close-form expression for BER is provided, which is expressed by a single integral. Moreover, the performance of random multiple access in the Direct-sequence code division multiple access (DS-CDMA) system with the capability of multiple packets reception is analyzed over Gaussian channel Rayleigh fading channel and Rice fad-ing channel, respectively, where the multiple packets reception is obtained by the method of match filter. The simulation results show that the MPR capability improves the throughput of DS-CDMA system greatly, compared with the conventional single packet reception. The system has the maximum throughput when signals are transmitted over the Gaussian channel. Also, the impact of Signal-to-noise ratio (SNR), channel coding and the traffic arrival model on the throughput of DS-CDMA system is given in the simulation and the analysis for the simulation results is provided.

    DNA damage attacks on bacterial cells have been known to activate the SOS response, a transcriptional response affecting chromosome replication, DNA recombination and repair, cell division and prophage induction. All these functions require double-stranded (ds) DNA translocation by ASCE hexameric motors. This review seeks to delineate the structural and functional characteristics of the SOS response and the SOS-regulated DNA translocases FtsK and RuvB with the phi29 bacteriophage packaging motor gp16 ATPase as a prototype to study bacterial motors. While gp16 ATPase, cellular FtsK and RuvB are similarly comprised of hexameric rings encircling dsDNA and functioning as ATP-driven DNA translocases, they utilize different mechanisms to accomplish separate functions, suggesting a convergent evolution of these motors. The gp16 ATPase and FtsK use a novel revolution mechanism, generating a power stroke between subunits through an entropy-DNA affinity switch and pushing dsDNA inward without rotation of DNA and the motor, whereas RuvB seems to employ a rotation mechanism that remains to be further characterized. While FtsK and RuvB perform essential tasks during the SOS response, their roles may be far more significant as SOS response is involved in antibiotic-inducible bacterial vesiculation and biofilm formation as well as the perspective of the bacteria-cancer evolutionary interaction.

    Magnetic resonance imaging (MRI) plays an important role in the treatment of breast tumor by high intensity focused ultrasound (HIFU). The doctors evaluate the scale, distribution and the statement of benign or malignancy of breast tumor by analyzing variety modalities of MRI, such as the T2, DWI and DCE images for making accurate preoperative treatment plan and evaluating the effect of the operation. This paper presents a method of lesion segmentation of breast tumor based on FCM-DS theory. Fuzzy c-means clustering (FCM) algorithm combined with Dempster-Shafer (DS) theory is used to process the uncertainty of information, segmenting the lesion areas on DWI and DCE modalities of MRI and reducing the scale of the uncertain parts. Experiment results show that FCM-DS can fuse the DWI and DCE images to achieve accurate segmentation and display the statement of benign or malignancy of lesion area by Time-Intensity Curve (TIC), which could be beneficial in making preoperative treatment plan and evaluating the effect of the therapy.

    We study the $\\bar{B}_s^0\\to D_s^-(DK)^+$ weak decay, and look at the $DK$ invariant mass distribution with the aim of obtaining relevant information on the nature of the $D_{s0}^{\\ast+}(2317)$ resonance. We make a simulation of the experiment using the actual mass of the $D_{s0}^{\\ast+}(2317)$ resonance and recent lattice QCD relevant parameters of the $KD$ scattering amplitude. We then solve the inverse problem of obtaining the $KD$ amplitude from these synthetic data, to which we have added a 5\\% or 10\\% error. We prove that one can obtain from these "data" the existence of a bound $KD$ state, the $KD$ scattering length and effective range, and most importantly, the $KD$ probability in the wave function of the bound state obtained, which was found to be largely dominant from the lattice QCD results. This means that one can obtain information on the nature of the $D_{s0}^{\\ast+}(2317)$ resonance from the implementation of this experiment, in the line of finding the structure of resonances, which is one of t...

    Full Text Available A numerical study is presented to investigate the electronic transport properties through a synthetic DNA molecule based on a quasiperiodic arrangement of its constituent nucleotides. Using a generalized Green's function technique, the electronic conduction through the poly(GACT-poly(CTGA DNA molecule in a metal/DNA/metal model structure has been studied. Making use of a renormalization scheme we transform the Hamiltonian of double-stranded DNA (dsDNA molecule to an effective Hamiltonian corresponding to a one-dimensional chain in which the effective on-site energies are arranged as a quasiperiodic lattice according to Fibonacci sequence. The room temperature current-voltage characteristic of dsDNA has been investigated in this Fibonacci model and compared with those corresponding to poly(GACT-poly(CTGA DNA molecule. Our results indicate the main effect of the quasiperiodic arrangement of the nucleotides as the Fibonacci sequence on the electronic spectrum structure of the dsDNA is that the energy band gaps of the molecule have a tendency for suppression. The room temperature I-V characteristic of the DNA Fibonacci model shows a linear and ohmic-like behavior

  16. Knockdown of midgut genes by dsRNA-transgenic plant-mediated RNA interference in the hemipteran insect Nilaparvata lugens.

    Directory of Open Access Journals (Sweden)

    Wenjun Zha

    Full Text Available BACKGROUND: RNA interference (RNAi is a powerful technique for functional genomics research in insects. Transgenic plants producing double-stranded RNA (dsRNA directed against insect genes have been reported for lepidopteran and coleopteran insects, showing potential for field-level control of insect pests, but this has not been reported for other insect orders. METHODOLOGY/PRINCIPAL FINDINGS: The Hemipteran insect brown planthopper (Nilaparvata lugens Stål is a typical phloem sap feeder specific to rice (Oryza sativa L.. To analyze the potential of exploiting RNAi-mediated effects in this insect, we identified genes (Nlsid-1 and Nlaub encoding proteins that might be involved in the RNAi pathway in N. lugens. Both genes are expressed ubiquitously in nymphs and adult insects. Three genes (the hexose transporter gene NlHT1, the carboxypeptidase gene Nlcar and the trypsin-like serine protease gene Nltry that are highly expressed in the N. lugens midgut were isolated and used to develop dsRNA constructs for transforming rice. RNA blot analysis showed that the dsRNAs were transcribed and some of them were processed to siRNAs in the transgenic lines. When nymphs were fed on rice plants expressing dsRNA, levels of transcripts of the targeted genes in the midgut were reduced; however, lethal phenotypic effects after dsRNA feeding were not observed. CONCLUSIONS: Our study shows that genes for the RNAi pathway (Nlsid-1 and Nlaub are present in N. lugens. When insects were fed on rice plant materials expressing dsRNAs, RNA interference was triggered and the target genes transcript levels were suppressed. The gene knockdown technique described here may prove to be a valuable tool for further investigations in N. lugens. The results demonstrate the potential of dsRNA-mediated RNAi for field-level control of planthoppers, but appropriate target genes must be selected when designing the dsRNA-transgenic plants.

    A novel water-dispersible conducting polymer analogous to poly(3,4-dioxythiophene):polystyrene sulfonate (PEDOT:PSS) has been chemically synthesized in a single reaction in high yield. PEDOT:DS, a new member of the polythiophene family, is composed of a complex between PEDOT and the sulfonated polysaccharide polyanion dextran sulfate. Drop-cast films of aqueous suspensions of the material display a native conductivity of up to 7 ± 1 S cm(-1), increasing to 20 ± 2 S cm(-1) after treatment with ethylene glycol and thermal annealing. Mass ratios of the precursors NaDS and EDOT were varied from 5:1 to 2:1 and a decrease in the NaDS:EDOT ratio produces tougher, less hygroscopic films of higher conductivity. Ultraviolet-visible spectroelectrochemistry yields spectra typical of PEDOT complexes. Cyclic voltammetry reveals that PEDOT:DS is electrochemically active from -1.0 to 0.8 V vs. Ag/Ag(+) in acetonitrile, with similar characteristics to PEDOT:PSS. Water dispersions of PEDOT:DS are successfully processed by drop casting, spray coating, inkjet printing and extrusion printing. Furthermore, laser etching of dried films allows the creation of patterns with excellent definition. To assess the cytotoxicity of PEDOT:DS, L-929 cells were cultured with a polymer complex concentration range of 0.002 to 0.2 g l(-1) in cell culture medium. No significant difference is found between the proliferation rates of L-929 cells exposed to PEDOT:DS and those in plain medium after 96h. However, PEDOT:PSS shows around 25% less cell growth after 4 days, even at the lowest concentration. Taken together, these results suggest PEDOT:DS has exceptional potential as an electromaterial for the biointerface.

    Using data collected with the LHCb detector in proton-proton collisions at a centre-of-mass energy of 7 TeV, the semileptonic decays Bs -> Ds+ X mu nu and Bs -> D0 K+ X mu nu are detected. Two structures are observed in the D0 K+ mass spectrum at masses consistent with the known D^+_{s1}(2536) and $D^{*+}_{s2}(2573) mesons. The measured branching fractions relative to the total Bs semileptonic rate are B(Bs -> D_{s2}^{*+} X mu nu)/B(Bs -> X mu nu)= (3.3\\pm 1.0\\pm 0.4)%, and B(Bs -> D_{s1}^+ X munu)/B(Bs -> X mu nu)= (5.4\\pm 1.2\\pm 0.5)%, where the first uncertainty is statistical and the second is systematic. This is the first observation of the D_{s2}^{*+} state in Bs decays; we also measure its mass and width.

    The interaction of amitrole and salmon sperm ds-DNA was studied using UV-vis and differential pulse voltammetry (DPV) at both bare and DNA-modified electrodes. Amitrole showed an oxidation peak at 0.445 V at a bare pencil graphite electrode (PGE). When ds-DNA was added into the amitrole solution, the peak current of amitrole decreased and the peak potential underwent a shift. UV-vis spectra showed that the absorption intensity of the ds-DNA at 260 nm decreased with increasing amitrole concentration, proving the interaction between amitrole and the ds-DNA. The results also showed that amitrole could interact with the ds-DNA molecules via the intercalative binding mode. Finally, a pretreated pencil graphite electrode (PGE) modified with multiwall carbon nanotubes (MWCNTs) and chitosan (CHIT) decorated with the ds-DNA were tested in order to determine amitrole content in solution. Electrochemical oxidation of amitrole bonded on DNA/MWCNTs-CHIT/PGE was used to obtain an analytical signal. A linear dependence was observed to exist between the peak current and 0.025-2.4 ng mL(-1) amitrole with a detection limit of 0.017 ng mL(-1). The sensor showed a good selectivity and precision for the determination of amitrole. Finally, applicability of the biosensor was evaluated by measuring the analyte in soil and water samples with good selectivity. Copyright © 2013 Elsevier B.V. All rights reserved.

    The preparation of polymeric membrane using affinity technology for application in blood filtration devices is described here. DNA attached poly(hydroxyethyl methacrylate) (PHEMA) based microporous affinity membrane was prepared for selective removal of anti-dsDNA antibodies from systemic lupus erythematosus (SLE) patient plasma in in vitro. In order to further increase blood-compatibility of affinity membrane, aminoacid based comonomer N-methacryloyl-L-alanine (MAAL) was included in the polymerization recipe. PHEMAAL membrane was produced by a photopolymerization technique and then characterized by swelling tests and scanning electron microscope (SEM) studies. Blood-compatibility tests were also performed. The water swelling ratio of PHEMAAL membrane increased significantly (133.2%) compared with PHEMA (58%). PHEMAAL membrane has large pores around in the range of 5-10 microm. All the clotting times increased when compared with PHEMA membrane. Loss of platelets and leukocytes was very low. DNA loading was 7.8 mg/g. There was a very low anti-dsDNA-antibody adsorption onto the plain PHEMAAL membrane, about 78 IU/g. The PHEMAAL-DNA membrane adsorbed anti-dsDNA-antibody in the range of 10-68 x 10(3)IU/g from SLE plasma. Anti-dsDNA-antibody concentration decreased significantly from 875 to 144 IU/ml with the time. Anti-dsDNA-antibodies could be repe
