  1. ISOON + SOLIS: Merging the Data Products (United States)

    Radick, R.; Dalrymple, N.; Mozer, J.; Wiborg, P.; Harvey, J.; Henney, C.; Neidig, D.


    The combination of AFRL's ISOON and NSO's SOLIS offers significantly greater capability than the individual instruments. We are working toward merging the SOLIS and ISOON data products in a single central facility. The ISOON system currently includes both an observation facility and a remote analysis center (AC). The AC is capable of receiving data from both the ISOON observation facility as well as external sources. It archives the data and displays corrected images and time-lapse animations. The AC has a large number of digital tools that can be applied to solar images to provide quantitative information quickly and easily. Because of its convenient tools and ready archival capability, the ISOON AC is a natural place to merge products from SOLIS and ISOON. We have completed a preliminary integration of the ISOON and SOLIS data products. Eventually, we intend to distribute viewing stations to various users and academic institutions, install the AC software tools at a number of user locations, and publish ISOON/SOLIS data products jointly on a common web page. In addition, SOLIS data products, separately, are and will continue to be fully available on the NSO,s Digital Library and SOLIS web pages, and via the Virtual Solar Observatory. This work is being supported by the National Science Foundation and the Air Force Office of Scientific Research.

  3. High Turbidity Solis Clear Sky Model: Development and Validation

    Directory of Open Access Journals (Sweden)

    Pierre Ineichen


    Full Text Available The Solis clear sky model is a spectral scheme based on radiative transfer calculations and the Lambert–Beer relation. Its broadband version is a simplified fast analytical version; it is limited to broadband aerosol optical depths lower than 0.45, which is a weakness when applied in countries with very high turbidity such as China or India. In order to extend the use of the original simplified version of the model for high turbidity values, we developed a new version of the broadband Solis model based on radiative transfer calculations, valid for turbidity values up to 7, for the three components, global, beam, and diffuse, and for the four aerosol types defined by Shettle and Fenn. A validation of low turbidity data acquired in Geneva shows slightly better results than the previous version. On data acquired at sites presenting higher turbidity data, the bias stays within ±4% for the beam and the global irradiances, and the standard deviation around 5% for clean and stable condition data and around 12% for questionable data and variable sky conditions.

    Yoo, Seung-Hee; Weon, Hang-Yeon; Kim, Byung-Yong; Hong, Seung-Beom; Kwon, Soon-Wo; Cho, Yang-Hee; Go, Seung-Joo; Stackebrandt, Erko


    A Gram-negative, obligately aerobic, rod-shaped bacterium was isolated from greenhouse soil used to cultivate lettuce. The strain, GH2-10T, was characterized on the basis of phenotypic and genotypic data. 16S rRNA gene sequence analysis revealed that the isolate belonged to the genus Devosia, with highest sequence similarity (98.5%) to Devosia riboflavina IFO 13584T. Sequence similarities with other strains tested were below 97.0%. Strain GH2-10T had Q-10 as the predominant ubiquinone and C18:1omega7c and C16:0 as the major fatty acids. The G+C content of the genomic DNA was 59.5 mol%. The results of DNA-DNA hybridization experiments (47% relatedness between D. riboflavina DSM 7230T and strain GH2-10T) and physiological and biochemical tests suggested that strain GH2-10T represents a novel species of the genus Devosia, for which the name Devosia soli sp. nov. is proposed. The type strain is GH2-10T (=KACC 11509T=DSM 17780T).

  5. Microvirga soli sp. nov., an alphaproteobacterium isolated from soil. (United States)

    Dahal, Ram Hari; Kim, Jaisoo


    An aerobic, Gram-stain-negative, catalase-positive and oxidase-negative, non-motile, non-spore-forming, rod-shaped, pink-pigmented bacterium designated strain R491T was isolated from soil. Flexirubin-type pigments were absent. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain R491T formed a lineage within the family Methylobacteriaceae of the phylum Proteobacteria that was distinct from various species of the genus Microvirga, including Microvirgaaerilata 5420S-16T (97.83 % 16S rRNA gene sequence similarity), Microvirga zambiensis WSM3693T (97.76 %), Microvirga flocculans ATCC BAA-817T (97.41 %), and Microvirga lupini Lut6T, Microvirga subterranea DSM 14364T, Microvirga vignae BR3299T, and Microvirga guangxiensis 25BT (96.99 %). The major polar lipids of strain R491T were phosphatidylcholine, phosphatidylglycerol and phosphatidylethanolamine. The major cellular fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c; 71.2 %), C16 : 0 (12.0 %), summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 4.7 %), and C18 : 0 (4.2 %). The DNA G+C content of strain R491T was 61.8 mol%. DNA-DNA hybridization values between strain R491T and other members of the genus Microvirga ranged from 27 to 57 %. On the basis of phenotypic, genotypic and phylogenetic analyses, strain R491T represents a novel species of the genus Microvirga, for which the name Microvirga soli sp. nov. is proposed. The type strain is R491T (=KEMB 9005-408T=KACC 18969T=NBRC 112417T).

  7. Biotransformation of ferulic acid to 4-vinylguaiacol by Enterobacter soli and E. aerogenes. (United States)

    Hunter, William J; Manter, Daniel K; van der Lelie, Daniel


    We investigated the conversion of ferulic acid to 4-vinylguaiacol (4-VG), vanillin, vanillyl alcohol, and vanillic acid by five Enterobacter strains. These high-value chemicals are usually synthesized by chemical methods but biological synthesis adds market value. Ferulic acid, a relatively inexpensive component of agricultural crops, is plentiful in corn hulls, cereal bran, and sugar-beet pulp. Two Enterobacter strains, E. soli, and E. aerogenes, accumulated 550-600 ppm amounts of 4-VG when grown in media containing 1,000 ppm ferulic acid; no accumulations were observed with the other strains. Decreasing the amount of ferulic acid present in the media increased the conversion efficiency. When ferulic acid was supplied in 500, 250, or 125 ppm amounts E. aerogenes converted ~72 % of the ferulic acid present to 4-VG while E. soli converted ~100 % of the ferulic acid to 4-VG when supplied with 250 or 125 ppm amounts of ferulic acid. Also, lowering the pH improved the conversion efficiency. At pH 5.0 E. aerogenes converted ~84 % and E. soli converted ~100 % of 1,000 ppm ferulic acid to 4-VG. Only small, 1-5 ppm, accumulations of vanillin, vanillyl alcohol, and vanillic acid were observed. E. soli has a putative phenolic acid decarboxylase (PAD) that is 168 amino acids long and is similar to PADs in other enterobacteriales; this protein is likely involved in the bioconversion of ferulic acid to 4-VG. E. soli or E. aerogenes might be useful as a means of biotransforming ferulic acid to 4-VG.

  8. Hybrid De Novo Genome Assembly Using MiSeq and SOLiD Short Read Data.

    Directory of Open Access Journals (Sweden)

    Tsutomu Ikegami

    Full Text Available A hybrid de novo assembly pipeline was constructed to utilize both MiSeq and SOLiD short read data in combination in the assembly. The short read data were converted to a standard format of the pipeline, and were supplied to the pipeline components such as ABySS and SOAPdenovo. The assembly pipeline proceeded through several stages, and either MiSeq paired-end data, SOLiD mate-paired data, or both of them could be specified as input data at each stage separately. The pipeline was examined on the filamentous fungus Aspergillus oryzae RIB40, by aligning the assembly results against the reference sequences. Using both the MiSeq and the SOLiD data in the hybrid assembly, the alignment length was improved by a factor of 3 to 8, compared with the assemblies using either one of the data types. The number of the reproduced gene cluster regions encoding secondary metabolite biosyntheses (SMB was also improved by the hybrid assemblies. These results imply that the MiSeq data with long read length are essential to construct accurate nucleotide sequences, while the SOLiD mate-paired reads with long insertion length enhance long-range arrangements of the sequences. The pipeline was also tested on the actinomycete Streptomyces avermitilis MA-4680, whose gene is known to have high-GC content. Although the quality of the SOLiD reads was too low to perform any meaningful assemblies by themselves, the alignment length to the reference was improved by a factor of 2, compared with the assembly using only the MiSeq data.

  9. The Constantinian «Dies Solis» Law in its Political and Legislative Context

    Directory of Open Access Journals (Sweden)



    Full Text Available The so-called «Dies Solis» Law, enacted by Constantine in 321, established the Day of the Sun as a public feast (dies festus in the Roman official calendar. This law can be studied in the political and legislative context between the first (314-315 and the second (324 civil war between Constantine and Licinius. This study reveals that its main purposes were the reinforcement of the imperial authority with administrative effects and the adoption, with propagandistic regards, of a religious policy on heathen cults different from the one developed by Licinius. The Dies Solis law is inscribed, in fact, in a joint of Constantinian norms that aim to make the imperial legislation an efficient instrument of government. Moreover, while Licinius promoted the hellenistic syncretic heathen cults, Constantine presented himself as a defender of the Roman religious traditions.

  10. A Novel Approach to Fast SOLIS Stokes Inversion for Photospheric Vector Magnetography. (United States)

    Harker, Brian; Mighell, K.


    The SOLIS (Synoptic Optical Long-term Investigations of the Sun) Vector Spectromagnetograph (VSM) is a full-disc spectropolarimeter, located at Kitt Peak National Observatory, which records Zeeman-induced polarization in the magnetically-sensitive FeI spectral lines at 630.15 nm and 630.25 nm. A SOLIS VSM full-disc dataset consists of 2048 scanlines, with each scanline containing the Stokes I, Q, U, and V spectral line profiles in 128 unique wavelength bins for all 2048 pixels in the scanline. These Stokes polarization profiles are inverted to obtain the magnetic and thermodynamic structure of the observations, based on a model Milne-Eddington plane-parallel atmosphere. Until recently, this has been a compute-intensive, relatively slow process. This poster presents a novel method of producing such model-based characterizations of the photospheric magnetic field by utilizing an inversion engine based on a genetic algorithm. The algorithm executes in a heterogeneous compute environment composed of both a CPU and a graphics processing unit (GPU). Using the cutting-edge NVIDIA CUDA platform, we are able to offload the compute-intensive portions of the inversion code to the GPU, which results in significant speedup. This speedup provides the impetus which has driven the development of this strategy. Currently, SOLIS vector magnetic field products are generated with a modified version of the HAO ASP inversion code developed by Skumanich & Lites (1987), and these data products are made available to the scientific community 24 hours after the actual observation(s). With this work, we aim to drastically reduce this waiting period to allow near real-time characterizations of the photospheric vector magnetic field. Here, we here detail the inversion method we have pioneered, present preliminary results on the derived full-disc magnetic field as well as timing/speedup considerations, and finally offer some outlooks on the future direction of this work.

  13. Jeotgalibacillus soli sp. nov., a Gram-stain-positive bacterium isolated from soil. (United States)

    Cunha, Sofia; Tiago, Igor; Paiva, Gabriel; Nobre, Fernanda; da Costa, Milton S; Veríssimo, António


    A Gram-staining-positive, motile, rod-shaped, spore-forming bacterium, designated P9(T), was isolated from soil in Portugal. This organism was aerobic and catalase- and oxidase-positive. It had an optimum growth temperature of about 35 °C and an optimum growth pH of about 8.0-8.5, and grew in medium with 0-9% (w/v) NaCl. The cell-wall peptidoglycan was of the A1α type, with L-lysine as the diagnostic diamino acid. The major respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were anteiso-C(15:0) (45.4%), iso-C(15:0) (22.0%) and anteiso-C(17:0) (11.2%). The genomic DNA G+C content was about 39.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain P9(T) was most closely related to Jeotgalibacillus campisalis DSM 18983(T) (96.8%) and Jeotgalibacillus marinus DSM 1297(T) (96.5%). These two recognized species formed a coherent cluster with strain P9(T) that was supported by a bootstrap value of 99%. On the basis of the phylogenetic analysis and physiological and biochemical characteristics, strain P9(T) (=DSM 23228(T)=LMG 25523(T)) represents a novel species of the genus Jeotgalibacillus, for which the name Jeotgalibacillus soli sp. nov. is proposed.

  14. Fine de novo sequencing of a fungal genome using only SOLiD short read data: verification on Aspergillus oryzae RIB40.

    Directory of Open Access Journals (Sweden)

    Myco Umemura

    Full Text Available The development of next-generation sequencing (NGS technologies has dramatically increased the throughput, speed, and efficiency of genome sequencing. The short read data generated from NGS platforms, such as SOLiD and Illumina, are quite useful for mapping analysis. However, the SOLiD read data with lengths of <60 bp have been considered to be too short for de novo genome sequencing. Here, to investigate whether de novo sequencing of fungal genomes is possible using only SOLiD short read sequence data, we performed de novo assembly of the Aspergillus oryzae RIB40 genome using only SOLiD read data of 50 bp generated from mate-paired libraries with 2.8- or 1.9-kb insert sizes. The assembled scaffolds showed an N50 value of 1.6 Mb, a 22-fold increase than those obtained using only SOLiD short read in other published reports. In addition, almost 99% of the reference genome was accurately aligned by the assembled scaffold fragments in long lengths. The sequences of secondary metabolite biosynthetic genes and clusters, whose products are of considerable interest in fungal studies due to their potential medicinal, agricultural, and cosmetic properties, were also highly reconstructed in the assembled scaffolds. Based on these findings, we concluded that de novo genome sequencing using only SOLiD short reads is feasible and practical for molecular biological study of fungi. We also investigated the effect of filtering low quality data, library insert size, and k-mer size on the assembly performance, and recommend for the assembly use of mild filtered read data where the N50 was not so degraded and the library has an insert size of ∼2.0 kb, and k-mer size 33.

  15. SOLIS IV. Hydrocarbons in the OMC-2 FIR4 Region, a Probe of Energetic Particle Irradiation of the Region (United States)

    Favre, C.; Ceccarelli, C.; López-Sepulcre, A.; Fontani, F.; Neri, R.; Manigand, S.; Kama, M.; Caselli, P.; Jaber Al-Edhari, A.; Kahane, C.; Alves, F.; Balucani, N.; Bianchi, E.; Caux, E.; Codella, C.; Dulieu, F.; Pineda, J. E.; Sims, I. R.; Theulé, P.


    We report new interferometric images of cyclopropenylidene, c-C3H2, toward the young protocluster OMC-2 FIR 4. The observations were performed at 82 and 85 GHz with the NOrthern Extended Millimeter Array (NOEMA) as part of the project Seeds Of Life In Space (SOLIS). In addition, IRAM-30 m data observations were used to investigate the physical structure of OMC-2 FIR 4. We find that the c-C3H2 gas emits from the same region where previous SOLIS observations showed bright HC5N emission. From a non-LTE analysis of the IRAM-30 m data, the c-C3H2 gas has an average temperature of ∼40 K, a H2 density of ∼3 × 105 cm‑3, and a c-C3H2 abundance relative to H2 of (7 ± 1) × 10‑12. In addition, the NOEMA observations provide no sign of significant c-C3H2 excitation temperature gradients across the region (about 3–4 beams), with T ex in the range 8 ± 3 up to 16 ± 7 K. We thus infer that our observations are inconsistent with a physical interaction of the OMC-2 FIR 4 envelope with the outflow arising from OMC-2 FIR 3, as claimed by previous studies. The comparison of the measured c-C3H2 abundance with the predictions from an astrochemical PDR model indicates that OMC-2 FIR 4 is irradiated by an FUV field ∼1000 times larger than the interstellar one, and by a flux of ionizing particles ∼4000 times larger than the canonical value of 1 × 10‑17 s‑1 from the Galaxy cosmic rays, which is consistent with our previous HC5N observations. This provides an important and independent confirmation of other studies that one, or more, source inside the OMC-2 FIR 4 region emits energetic (≥10 MeV) particles.

  16. Two new species of dicyemid mesozoans (Dicyemida: Dicyemidae) from Octopus maya Voss & Solis-Ramirez (Octopodidae) off Yucatan, Mexico. (United States)

    Castellanos-Martinez, Sheila; Aguirre-Macedo, M Leopoldina; Furuya, Hidetaka


    Two new dicyemid species are described from the endemic cephalopod Octopus maya Voss & Solis-Ramirez collected off Yucatan, Mexico. The renal sacs of 40 juvenile and adult octopuses from four localities were examined. Dicyema hochbergi n. sp. is a medium-sized species that reaches 2,245 µm in length. The vermiform stages consist of 18-24 peripheral cells, a conical calotte and the extension of the axial cell between the base and middle of the metapolar cells. Infusoriform embryos consist of 39 cells with urn cell containing one germinal cell, two nuclei and solid refringent bodies. Dicyema mexcayae n. sp. is a relatively small species that reaches 1,114 µm in length. The vermiform stages are constituted by 14-16 peripheral cells, an elongate calotte and the axial cell extending forward to the middle of the metapolar cells. The infusoriform embryos consist of 37 cells, two solid refringent bodies and urn cells with two nuclei each. The present study represents the first description of a dicyemid species from O. maya and increases the number of described species from Mexican waters to 11.

    Toward the prestellar core L1544, the methanol (CH3OH) emission forms an asymmetric ring around the core center, where CH3OH is mostly in solid form, with a clear peak at 4000 au to the northeast of the dust continuum peak. As part of the NOEMA Large Project SOLIS (Seeds of Life in Space), the CH3OH peak has been spatially resolved to study its kinematics and physical structure and to investigate the cause behind the local enhancement. We find that methanol emission is distributed in a ridge parallel to the main axis of the dense core. The centroid velocity increases by about 0.2 km s‑1 and the velocity dispersion increases from subsonic to transonic toward the central zone of the core, where the velocity field also shows complex structure. This could be an indication of gentle accretion of material onto the core or the interaction of two filaments, producing a slow shock. We measure the rotational temperature and show that methanol is in local thermodynamic equilibrium (LTE) only close to the dust peak, where it is significantly depleted. The CH3OH column density, N tot(CH3OH), profile has been derived with non-LTE radiative transfer modeling and compared with chemical models of a static core. The measured N tot(CH3OH) profile is consistent with model predictions, but the total column densities are one order of magnitude lower than those predicted by models, suggesting that the efficiency of reactive desorption or atomic hydrogen tunneling adopted in the model may be overestimated; or that an evolutionary model is needed to better reproduce methanol abundance. This work is based on observations carried out under project number L15AA with the IRAM NOEMA Interferometer and on observations carried out with the IRAM 30 m telescope.

  18. SOLiD sequencing of four Vibrio vulnificus genomes enables comparative genomic analysis and identification of candidate clade-specific virulence genes

    Directory of Open Access Journals (Sweden)

    Telonis-Scott Marina


    Full Text Available Abstract Background Vibrio vulnificus is the leading cause of reported death from consumption of seafood in the United States. Despite several decades of research on molecular pathogenesis, much remains to be learned about the mechanisms of virulence of this opportunistic bacterial pathogen. The two complete and annotated genomic DNA sequences of V. vulnificus belong to strains of clade 2, which is the predominant clade among clinical strains. Clade 2 strains generally possess higher virulence potential in animal models of disease compared with clade 1, which predominates among environmental strains. SOLiD sequencing of four V. vulnificus strains representing different clades (1 and 2 and biotypes (1 and 2 was used for comparative genomic analysis. Results Greater than 4,100,000 bases were sequenced of each strain, yielding approximately 100-fold coverage for each of the four genomes. Although the read lengths of SOLiD genomic sequencing were only 35 nt, we were able to make significant conclusions about the unique and shared sequences among the genomes, including identification of single nucleotide polymorphisms. Comparative analysis of the newly sequenced genomes to the existing reference genomes enabled the identification of 3,459 core V. vulnificus genes shared among all six strains and 80 clade 2-specific genes. We identified 523,161 SNPs among the six genomes. Conclusions We were able to glean much information about the genomic content of each strain using next generation sequencing. Flp pili, GGDEF proteins, and genomic island XII were identified as possible virulence factors because of their presence in virulent sequenced strains. Genomic comparisons also point toward the involvement of sialic acid catabolism in pathogenesis.

    Lin, Shih-Yao; Hameed, Asif; Arun, A B; Liu, You-Cheng; Hsu, Yi-Han; Lai, Wei-An; Rekha, P D; Young, Chiu-Chung


    An aerobic, Gram-negative, rod-shaped bacterium with polar flagella, strain CC-AFH3(T), was isolated from an oil-contaminated site located in Kaohsiung county, Taiwan. Strain CC-AFH3(T) grew at 20-40 °C, pH 5.0-10.0 and Herbaspirillum soli SUEMI10(T) (96.5 %), H. aurantiacum SUEMI08(T) (96.3 %), H. canariense SUEMI03(T) (96.0 %), H. psychrotolerans PB1(T) (95.4 %) and members of other Herbaspirillum species (94.1-95.2 %), and lower similarity to members of other genera (Herbaspirillum as an independent lineage. The major fatty acids in strain CC-AFH3(T) were C10 : 0 3-OH, C12 : 0, C14 : 0 2-OH, C16 : 0, iso-C15 : 0 3-OH, C17 : 0 cyclo, C16 : 1ω7c/C16 : 1ω6c and C18 : 1ω7c/C18 : 1ω6c. The major polar lipids of strain CC-AFH3(T) were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine. The predominant quinone was ubiquinone 8 (Q-8) and the DNA G+C content was 63.4 mol%. On the basis of 16S rRNA gene sequence analysis in combination with physiological and chemotaxonomic data, strain CC-AFH3(T) represents a novel species in a new genus, for which we propose the name Noviherbaspirillum malthae gen. nov., sp. nov.; the type strain of Noviherbaspirillum malthae is CC-AFH3(T) ( = BCRC 80516(T) = JCM 18414(T)). We also propose the reclassification of Herbaspirillum soli, Herbaspirillum aurantiacum, Herbaspirillum canariense and 'Herbaspirillum psychrotolerans' as Noviherbaspirillum soli comb. nov. (type strain SUEMI10(T) = LMG 26149(T) = CECT 7840(T)), Noviherbaspirillum aurantiacum comb. nov. (type strain SUEMI08(T) = LMG 26150(T) = CECT 7839(T)), Noviherbaspirillum canariense comb. nov. (type strain SUEMI03(T) = LMG 26151(T) = CECT 7838(T)) and Noviherbaspirillum psychrotolerans comb. nov. (type strain PB1(T) = DSM 26001(T) = LMG 27282(T)), respectively.

  20. Transcription profiling of the model cyanobacterium Synechococcus sp. strain PCC 7002 by NextGen (SOLiD™ Sequencing of cDNA

    Directory of Open Access Journals (Sweden)

    Marcus eLudwig


    Full Text Available The genome of the unicellular, euryhaline cyanobacterium Synechococcus sp. PCC 7002 encodes about 3200 proteins. Transcripts were detected for nearly all annotated open reading frames by a global transcriptomic analysis by Next-Generation (SOLiDTM sequencing of cDNA. In the cDNA samples sequenced, ~90% of the mapped sequences were derived from the 16S and 23S ribosomal RNAs and ~10% of the sequences were derived from mRNAs. In cells grown photoautotrophically under standard conditions (38 °C, 1% (v/v CO2 in air, 250 µmol photons m-2 s-1, the highest transcript levels (up to 2% of the total mRNA for the most abundantly transcribed genes (e. g., cpcAB, psbA, psaA were generally derived from genes encoding structural components of the photosynthetic apparatus. High light exposure for one hour caused changes in transcript levels for genes encoding proteins of the photosynthetic apparatus, Type-1 NADH dehydrogenase complex and ATP synthase, whereas dark incubation for one hour resulted in a global decrease in transcript levels for photosynthesis-related genes and an increase in transcript levels for genes involved in carbohydrate degradation. Transcript levels for pyruvate kinase and the pyruvate dehydrogenase complex decreased sharply in cells incubated in the dark. Under dark anoxic (fermentative conditions, transcript changes indicated a global decrease in transcripts for respiratory proteins and suggested that cells employ an alternative phosphoenolpyruvate degradation pathway via phosphoenolpyruvate synthase (ppsA and the pyruvate:ferredoxin oxidoreductase (nifJ. Finally, the data suggested that an apparent operon involved in tetrapyrrole biosynthesis and fatty acid desaturation, acsF2-ho2-hemN2-desF, may be regulated by oxygen concentration.

  1. SOLiD™ sequencing of genomes of clinical isolates of Leishmania donovani from India confirm leptomonas co-infection and raise some key questions.

    Full Text Available BACKGROUND: Known as 'neglected disease' because relatively little effort has been applied to finding cures, leishmaniasis kills more than 150,000 people every year and debilitates millions more. Visceral leishmaniasis (VL, also called Kala Azar (KA or black fever in India, claims around 20,000 lives every year. Whole genome analysis presents an excellent means to identify new targets for drugs, vaccine and diagnostics development, and also provide an avenue into the biological basis of parasite virulence in the L. donovani complex prevalent in India. METHODOLOGY/PRINCIPAL FINDINGS: In our presently described study, the next generation SOLiD™ platform was successfully utilized for the first time to carry out whole genome sequencing of L. donovani clinical isolates from India. We report the exceptional occurrence of insect trypanosomatids in clinical cases of visceral leishmaniasis (Kala Azar patients in India. We confirm with whole genome sequencing analysis data that isolates which were sequenced from Kala Azar (visceral leishmaniasis cases were genetically related to Leptomonas. The co-infection in splenic aspirate of these patients with a species of Leptomonas and how likely is it that the infection might be pathogenic, are key questions which need to be investigated. We discuss our results in the context of some important probable hypothesis in this article. CONCLUSIONS/SIGNIFICANCE: Our intriguing results of unusual cases of Kala Azar found to be most similar to Leptomonas species put forth important clinical implications for the treatment of Kala Azar in India. Leptomonas have been shown to be highly susceptible to several standard leishmaniacides in vitro. There is very little divergence among these two species viz. Leishmania sp. and L. seymouri, in terms of genomic sequence and organization. A more extensive perception of the phenomenon of co-infection needs to be addressed from molecular pathogenesis and eco

  2. Herbaspirillum canariense sp. nov., Herbaspirillum aurantiacum sp. nov. and Herbaspirillum soli sp. nov., isolated from volcanic mountain soil, and emended description of the genus Herbaspirillum. (United States)

    Carro, Lorena; Rivas, Raúl; León-Barrios, Milagros; González-Tirante, María; Velázquez, Encarna; Valverde, Angel


    Three Gram-negative, motile and slightly curved rod-shaped bacteria, strains SUEMI03(T), SUEMI08(T) and SUEMI10(T), were isolated from an old volcanic mountain soil on Tenerife (Canary Islands). The three strains were related phylogenetically to Herbaspirillum seropedicae. 16S rRNA gene sequence similarity was 99.2-99.6 % among strains SUEMI03(T), SUEMI08(T) and SUEMI10(T), which presented 97.5, 97.8 and 97.7 % identity, respectively, with respect to H. seropedicae DSM 6445(T). The three strains grew optimally in TSB at 28 °C and contained summed features 3 (C(16:1)ω6c and/or C(16:1)ω7c) and 8 (C(18:1)ω6c and/or C(18:1)ω7c) and C(16:0) as major cellular fatty acids. The DNA G+C contents of strains SUEMI03(T), SUEMI08(T) and SUEMI10(T) were 61.6, 60.4 and 61.9 mol%, respectively. Strains SUEMI03(T), SUEMI08(T) and SUEMI10(T) presented less than 60 % interstrain DNA relatedness and less than 30 % relatedness with respect to H. seropedicae DSM 6445(T). In spite of their common geographical origin, the three strains isolated in this study presented several phenotypic differences, presenting phenotypic profiles highly divergent from that of H. seropedicae. Therefore, we propose that the strains isolated in this study represent three novel species of the genus Herbaspirillum, named Herbaspirillum canariense sp. nov. (type strain SUEMI03(T) = LMG 26151(T) = CECT 7838(T)), Herbaspirillum aurantiacum sp. nov. (type strain SUEMI08(T) = LMG 26150(T) = CECT 7839(T)) and Herbaspirillum soli sp. nov. (type strain SUEMI10(T) = LMG 26149(T) = CECT 7840(T)).

    Monika Sirkovská


    Full Text Available Author in the contribution devote to research of authority and subordination in the family from the perspective of visual anthropology. Everyday family life is controlled by a set of culturally specific values and norms that determine the appropriate family ideology. Research of the family dynamics can provide the basic image of the various forms of relationships. Author realized research of power manifestations in the mountain village at the north of Slovakia which is characterized by frequent occurrence of the patriarchal family. The authority in the patriarchal family ideology is attributed to older men belonging to the paternal lineage; it is typically associated with patrilineality, patrilocality and focusing on ancestors. The question is how can we explore the subjective perception of authority in the case of children. It seems to be very helpful to apply the special projective technique – the family drawing test. Aim of this contribution is to show not only interface between theoretical concepts and practical collection of empirical data in the field, but also the interpretation of specific children's drawings. End-of-conference, author would like to highlight that anthropologist has to detect the specific socio-cultural environment of studied families, because its knowledge plays the key role in the complex interpretation of visual material.

  12. Etika ako prvá filozofia podľa Pierra Hadota (Ethics as a First Philosophy after Pierre Hadot

    Directory of Open Access Journals (Sweden)

    Michal Zvarík


    Full Text Available The review study focused on Czech translation of Pierre Hadot’s Qu’est-ce que la philosophie antique? is divided into three parts. In the first part the motivation behind the question “what is ancient philosophy?” is considered. On the one hand, Hadot aims to show that usual contemporary understanding of philosophy with its emphasis on discourse and theory does not provide adequate perspective to interpret ancient philosophy in its own right and thus the question on its nature must be asked anew. On the other hand, Hadot sees the core of ancient philosophy in specific praxis, not in theory, and this concept serves as norm for critical revision of the contemporary philosophy. The second part is addressed to the content of the chapters. The study accentuates that Hadot offers not only a description of various ancient philosophical schools and movements, but also presents a certain genealogy of the contemporary understanding of philosophy. The final part is dedicated to brief critical assessment of Hadot’s book and draws several conclusions concerning the institutional character of philosophy with regard to present crisis of humanities from its perspective.

  15. Simplicispira soli sp. nov., a betaproteobacterium isolated from stream bank soil. (United States)

    Dahal, Ram Hari; Kim, Jaisoo


    Two strains of soil bacteria, designated CA-16 T and CA-161, were isolated from a sample of stream bank soil near Kyonggi University. Cells were strictly aerobic, Gram-stain-negative, catalase-negative, oxidase-positive, motile, non-spore-forming and rod-shaped. Colonies on tryptone soya agar were brownish cream in colour. Tyrosine, Tween 60 and Tween 40 were hydrolysed. The indole test was positive. Malic acid, lactic acid and valeric acid were assimilated. Phylogenetic analysis based on their 16S rRNA gene sequences revealed that strains CA-16 T and CA-161 formed a lineage within the family Comamonadaceae of the class Betaproteobacteria that were distinct from various species of the genus Simplicispira. Strain CA-16 T was most closely related to Simplicispira metamorpha DSM 1837 T (97.86 % sequence similarity), Simplicispira limi EMB325 T (97.72 %), Simplicispira psychrophila DSM 11588 T (96.83 %) and Simplicispira piscis RSG39 T (96.71 %). Both strains contained Q-8 as the major isoprenoid quinone. The major polar lipids of the strains were phosphatidylglycerol, phosphatidylethanolamine and diphosphatidylglycerol. The major cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C18 : 1ω7c-11methyl, C16 : 0, summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C12 : 0. The DNA G+C contents of the strains were 63.9-64.4 mol%. DNA-DNA hybridization similarities between strain CA-16 T and other closest members of the genus Simplicispira ranged from 16 % to 24 %. On the basis of phenotypic, genotypic, chemotaxonomic and phylogenetic analyses, strains CA-16 T and CA-161 represent a single novel species of the genus Simplicispira, for which the name Simplicispirasoli sp. nov. is proposed. The type strain is CA-16 T (=KEMB 9005-529 T =KACC 19107 T =NBRC 112689 T ).

  16. Ferrovibrio soli sp. nov., a novel cellulolytic bacterium isolated from stream bank soil. (United States)

    Two isolates of bacterial strains A15 T and A17 were isolated from stream bank soil in Kyonggi University. Cells were aerobic, Gram-stain-negative, oxidase- and catalase-positive, motile, non-spore-forming, rod-shaped, opaque, and cream coloured. Both strains hydrolysed CM-cellulose. Strains were able to grow at 20-42 °C, pH 5.5-10.0 and at 1.5 % NaCl concentration (w/v). Indole test was positive. Analyses of phylogenetic trees based on its 16S rRNA gene sequences indicated that strain A15 T formed a lineage within the family Rhodospirillaceae of the phylum Proteobacteria which was distinct from Ferrovibrio denitrificans S3 T (98.4 % sequence similarity) and Ferrovibrio xuzhouensis LM-6 T (97.4 %). The sole detected respiratory quinone was Q-10. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and an unidentified aminolipid. The major cellular fatty acids were C19 : 0 cycloω8c, C16 : 0, summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), C18 : 0cyclo and C12 : 0. The DNA G+C contents of strains A15 T and A17 were 63.4 and 62.9 mol%, respectively. DNA-DNA relatedness between strain A15 T and other two members of the genus Ferrovibrioranged from 25 to 37 %. The polyphasic characterization revealed strains A15 T and A17 represent a novel species in the genus Ferrovibrio, for which the name Ferrovibriosoli sp. nov. is proposed. The type strain is A15 T (=KEMB 9005-522 T =KACC 19102 T =NBRC 112682 T ).

    Kusch, S.


    In contrary to the municipal waste processing in agricultural areas the biogas production based on solid materials is still in a phase of development. A possible processing approach is the discontinuously operated box fermenter with irrigation. Based on associated features like robustness, flexibility and utilizability in agricultural farms without liquid manure this type of fermenter is quite attractive.The author describes the laboratory and field tests and discusses possible applications, including procedural boundary conditions using different materials and problematic aspects. Possibilities for process optimizations are given.

  18. La ricerca di nuova fisica a LEP mediante lo studio di eventi con soli fotoni nello stato finale

    CERN Document Server

    Verlato, M


    A wide search for new physics can be performed at LEP carefully analysing the events having two or more photons in the final state. As a first example, the direct production of a couple of photons, each one having the LEP beam energy, is at tree level a pure QED process, with a negligible electroweak loop contribution. Possible deviation from the QED predictions could arise in the angular differential cross section, as a result of an alteration of the Coulomb potential at distances shorter than about 10^-16 cm. The highest sensitivity to this deviation is at the highest center-of-mass energy (183 GeV) data collected at LEP in 1997. At energies around Z resonance, new physics beyond the Standard Model could be detected observing some Z decays into neutral final states, such as the direct decay into two photon, forbidden from angular momentum conservation and Bose statistic, or very low rate predicted decays into three photons or into a neutral light meson plus a photon, with subsequent meson decay into two or ...

    Full Text Available This article deals with the power of laugh as an expression of a human evoked by emotional, cognitive, physiological, and expressive changes which cause further changes in another person and society. Ambivalence is one of the basic characteristics of laugh which is why it cannot be fullly grasped in theory, even though it has been proved that joy expressed by laugh is the most universal emotion. Examples from movies serve well to observe laugh as a form of social gesture in contemporary society.

  2. Peniaze ako zdroj šťastia v našich životoch? (Is Money a Source of Happiness in our lives?

    Directory of Open Access Journals (Sweden)

    Otakar Horák


    Full Text Available This paper begins by referring to the research which distinguishes two different aspects of subjective well-being, namely 1. experiences of happiness – measured by frequency and intensity of joy, stress, anger, worry and sadness we experience at a certain moment and 2. life satisfaction. Survey shows that beyond an annual household income of $75 000 there is no increase in the experiences of happiness. The paper then refers to the psychological mechanisms and factors – namely hedonic adaptation, social comparison and stress as a result of a raise – that lower the capacity of money to buy us the experiences of happiness. Not only we get quickly used to the things we buy, money also puts us into stressful situations and makes us build barriers between people. The paper then specifies strategies of economic decision-making that contribute to the maximization of happiness, such as purchase of the experiences instead of the things, interrupted and postponed consumption, or prosocial spending. The research indicates that prosocial spending has higher causal impact on promoting happiness than personal spending. As a matter of fact, this phenomenon is not culturally limited to the West. Concluding assertion – expressed only in the form of hypothesis – says that prosocial spending which is a form of prosocial behavior strengthens – through production of happiness – mutual relations in the society (cooperation.

  3. Cnosť ako most medzi Aristotelovou rétorikou a etikou? ( Virtue as a Bridge between Aristotle’s Ethics and Rhetoric?

    Directory of Open Access Journals (Sweden)

    Michal Zvarík


    Full Text Available The article deals with the issue of relation between Aristotle’s ethics and art of rhetoric. On the one hand, his concept of rhetoric stresses its instrumental, morally neutral character, which is substantial for every art. On the other hand, it seems that for Aristotle if speaker is truly good rhetorician and persuades truthfully and for just cause, his speech should appear more persuasive than in case of artful defence of injustice. Thus, truthfulness and justice appear to have inherent persuasive effect. In order to clarify the relation between ethical and rhetorical normative claims author highlights distinctive character of art in comparison to Aristotle’s concepts of moral virtue and prudence (phronēsis and shows how this character of art is integrated into Aristotle’s concept of rhetoric and how it transforms the function of virtue in the scope of rhetorical activity. The primary goal of rhetorician is not to be moral, but merely to appear as such. This conclusion does not call for rejection of rhetoric in the eyes of prudent person. Rather, it is useful, because it provides means to realize ends that are in favour of good life of the city and his fellow citizens.

  7. Competing Victimizations or Multidirectional Soli-daties? Politics of Collective Memory and Solidarity in the Post-National Socialist and Post-Colonial Austrian Left

    Directory of Open Access Journals (Sweden)

    Julia Edthofer


    Full Text Available In this article I illustrate “competing victimizations” and propose possible “multidirectional solidarities” regarding inner-left debates about the Middle East conflict, anti-Semitism and racism in Viennese left-wing contexts. The illustrated conflict is specific for radical left-wing politics in a post-National Socialist and post-colonial setting. Debates initially revolve around Israel versus Palestine solidarity. In the wake of the Second Intifada and the September 11 attacks they partly divide anti-fascist and anti-racist political stances. While the pro-Israeli camp focuses on the Holocaust, Austrian guilt-deflection and current anti-Semitism, the pro-Palestinian side condemns the Israeli occupation and fights growing anti-Muslim racism. In this context, opposing perspectives on the relation of new anti-Semitism and anti-Muslim racism are articulated. Such competing dynamics and their interrelation with Austrian memory politics and global politics are illustrated.  Subsequently, they are discussed as being related to conflicting memories and interrelated competing victimizations in migrant societies with a National Socialist history, such as in Austria and Germany. Concluding, the concept of “multidirectional solidarity” is proposed as an alternative approach, transcending competitive views on past and current victimizations.

  14. Arboreas voces solis luneque loquentes: la visita de Alejandro Magno a los árboles del sol y de la luna en las crónicas del siglo XII

    Directory of Open Access Journals (Sweden)

    José Miguel De Toro Vidal


    Full Text Available El encuentro de Alejandro Magno con los árboles parlantes del Sol y de la Luna en un bosque sagrado de la India, constituye uno de los muchos episodios maravillosos de la leyenda alejandrina difundida en la Edad Media. El objetivo del presente artículo es estudiar el momento en que los cronistas deciden incorporar este pasaje en sus obras e indagar en las causas de esta decisión. Para ello se han revisado las crónicas universales del siglo XII y principios del XIII, cotejándolas con otras obras producidas en la época. Se aprecia que tanto la Historia Scholastica de Pedro Coméstor como los mapamundis contribuyeron a la aceptación del episodio. No obstante, la inclusión del pasaje en las crónicas no obedece tanto a la afirmación del encuentro con los árboles como un hecho cierto de la historia, sino al proyecto histórico-literario previsto por el autor de cada crónica.

  15. Causes and Consequences of Water Flux on the Example of Transverse Heading Mina in the Salt Mine "Wieliczka" / Przyczyny i Skutki Dopływu Wody na Przykładzie Poprzeczni Mina w Kopalni Soli "Wieliczka" (United States)

    Gonet, Andrzej; Stryczek, Stanisław; Brudnik, Krzysztof


    The causes of disastrous water flux in the historical Salt Mine "Wieliczka" have been presented on the example of transverse heading Mina at the IV level at a depth of 175 m bsl. The complex geological setting of direct environment of the transverse heading Mina has been described paying attention to unfavorable hydrogeological conditions in the northern part of the salt deposit. The main activities oriented to limiting the water hazard in the Salt Mine "Wieliczka" and the reconstruction of inner safety pillar, which had been seriously damaged by mining activities, have been analyzed. A selection of objects inside the mine, saved from flooding thanks to protection works has been visualized in photos.

  18. Platón ako Pseudo-Sókratés? Niekoľko poznámok k problematike autorstva filozofického textu v antike ( “Plato as Pseudo-Socrates? Some Remarks on the Problems Related to the Autorship of a Philosophical Text in Antiquity“

    Directory of Open Access Journals (Sweden)

    František Škvrnda ml.


    Full Text Available The following paper deals with the problematic category of authorship in ancient philosophical literature. Philosophers are divided into two groups: the first consist of non-writing protagonists (e. g. Socrates, Ammonius of Saccas, while the second category includes writing authors (e. g. Plato, Aristotle. Paper argues that with regard to their „historicity“, between these two groups of philosophers is no substantial difference. Philosophical texts were often written in co-authorship. Many students and later adherents passed their own doctrines off as teacherʼs originals. Moreover, due to the fact that the very texts were transcribed countless times, there is no certainty about original phrasing of the documents that came down to our modern or renaissance era. The „historicity“ of philosophersʼ attitudes and ideas therefore can not be deduced from the existence of authorized text, written by some particular author.

  19. The annual school reports as artefacts of book culture and sources on the history of Jewish education in Slovakia (Výročné správy škôl ako artefakty knižnej kultúry a pramene k dejinám židovského školstva na Slovensku

    Directory of Open Access Journals (Sweden)

    Kamila Fircáková


    Full Text Available This paper outlines the history of the annual school reports publishing on the terri-tory of Slovakia. It also provides the basic bibliographic sources in which the annual school reports are registered. The annual school reports began to be systematically published in the second half of the 19th century. Also the Jewish schools, which history is much older (e. g. a school existed at the synagogue in Bratislava as early as 1416 published them. During the extensive research in libraries in Slovakias well as 21 titles of the annual school reports of some Jewish schools published in Slovakia until 1918 were found. The annual school reports of the primary schools, business schools, religious schools (the so-called talmudtóra, boys‘ schools, girls‘ schools and co-educational schools are among them. The content of the annual school reports of Jewish schools is presented in the example of the annual school report of the boys‘ public school associated with the business school in Bratislava and public school in Liptovsky Mikulas. As artefacts of book culture they are an especially a rich source of information about a particular school, they document publishing activities of a school or its founders and complete the knowledge about production of individual printers and printing houses. Through the ownership stamps and records they provide information about previous owners and assist in the reconstruction of the library stocks. At the moment known annual school reports of Jewish schools are certainly only a part of a larger, not yet fully discovered corpus (e. g. we can assume the existence of the annual school reports of the higher schools - yeshivas in Hebrew. Their systematic research, documentation and expert processing should become part of research and protection of Jewish cultural heritage in Slovakia.

  20. The Protective Effect of Antarctic Krill Oil on Cognitive Function by Inhibiting Oxidative Stress in the Brain of Senescence-Accelerated Prone Mouse Strain 8 (SAMP8) Mice. (United States)

    Li, Qian; Wu, Fengjuan; Wen, Min; Yanagita, Teruyoshi; Xue, Changhu; Zhang, Tiantian; Wang, Yuming


    Alzheimer's disease (AD) is a common neurodegenerative disorder, and oxidative stress plays a vital role in its progression. Antarctic krill oil (AKO) is rich in polyunsaturated fatty acids, which has various biological activities, such as improving insulin sensitivity, alleviating inflammation and ameliorating oxidative stress. In this study, the protective effect of AKO against AD were investigated in senescence-accelerated prone mouse strain 8 (SAMP8) mice. Results showed that treatment with AKO could effectively ameliorate learning and memory deficits and ease the anxiety in SAMP8 mice by Morris water maze, Barnes maze test and open-field test. Further analysis indicated that AKO might reduce β-amyloid (Aβ) accumulation in hippocampus through decreasing the contents of malondialdehyde (MDA) and 7,8-dihydro-8-oxoguanine (8-oxo-G), increasing the superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities in the brain of SAMP8 mice. The results of Morris water maze, Barnes maze test and open-field test indicated that Antarctic krill oil (AKO) improved the cognitive function and anxiety of SAMP8 mice. AKO reduced the Aβ 42 level in hippocampus of SAMP8 mice. AKO ameliorated oxidative stress in brain rather than in serum and liver of SAMP8 mice. © 2018 Institute of Food Technologists®.

  6. Members of WRKY Group III transcription factors are important in TYLCV defense signaling pathway in tomato (Solanum lycopersicum). (United States)

    Huang, Ying; Li, Meng-Yao; Wu, Peng; Xu, Zhi-Sheng; Que, Feng; Wang, Feng; Xiong, Ai-Sheng


    Transmitted by the whitefly Bemisia tabaci, tomato yellow leaf curly virus (TYLCV) has posed serious threats to plant growth and development. Plant innate immune systems against various threats involve WRKY Group III transcription factors (TFs). This group participates as a major component of biological processes in plants. In this study, 6 WRKY Group III TFs (SolyWRKY41, SolyWRKY42, SolyWRKY53, SolyWRKY54, SolyWRKY80, and SolyWRKY81) were identified, and these TFs responded to TYLCV infection. Subcellular localization analysis indicated that SolyWRKY41 and SolyWRKY54 were nuclear proteins in vivo. Many elements, including W-box, were found in the promoter region of Group III TFs. Interaction network analysis revealed that Group III TFs could interact with other proteins, such as mitogen-activated protein kinase 5 (MAPK) and isochorismate synthase (ICS), to respond to biotic and abiotic stresses. Positive and negative expression patterns showed that WRKY Group III genes could also respond to TYLCV infection in tomato. The DNA content of TYLCV resistant lines after SolyWRKY41 and SolyWRKY54 were subjected to virus-induced gene silencing (VIGS) was lower than that of the control lines. In the present study, 6 WRKY Group III TFs in tomato were identified to respond to TYLCV infection. Quantitative real-time-polymerase chain reaction (RT-qPCR) and VIGS analyses demonstrated that Group III genes served as positive and negative regulators in tomato-TYLCV interaction. WRKY Group III TFs could interact with other proteins by binding to cis elements existing in the promoter regions of other genes to regulate pathogen-related gene expression.

  7. Reduced Dnmt3a increases Gdf5 expression with suppressed satellite cell differentiation and impaired skeletal muscle regeneration. (United States)

    Hatazawa, Yukino; Ono, Yusuke; Hirose, Yuma; Kanai, Sayaka; Fujii, Nobuharu L; Machida, Shuichi; Nishino, Ichizo; Shimizu, Takahiko; Okano, Masaki; Kamei, Yasutomi; Ogawa, Yoshihiro


    DNA methylation is an epigenetic mechanism regulating gene expression. In this study, we observed that DNA methyltransferase 3a (Dnmt3a) expression is decreased after muscle atrophy. We made skeletal muscle-specific Dnmt3a-knockout (Dnmt3a-KO) mice. The regeneration capacity after muscle injury was markedly decreased in Dnmt3a-KO mice. Diminished mRNA and protein expression of Dnmt3a were observed in skeletal muscles as well as in satellite cells, which are important for muscle regeneration, in Dnmt3a-KO mice. Dnmt3a-KO satellite cell showed smaller in size (length/area), suggesting suppressed myotube differentiation. Microarray analysis of satellite cells showed that expression of growth differentiation factor 5 (Gdf5) mRNA was markedly increased in Dnmt3a-KO mice. The DNA methylation level of the Gdf5 promoter was markedly decreased in Dnmt3a-KO satellite cells. In addition, DNA methylation inhibitor azacytidine treatment increased Gdf5 expression in wild-type satellite cells, suggesting Gdf5 expression is regulated by DNA methylation. Also, we observed increased inhibitor of differentiation (a target of Gdf5) mRNA expression in Dnmt3a-KO satellite cells. Thus, Dnmt3a appears to regulate satellite cell differentiation via DNA methylation. This mechanism may play a role in the decreased regeneration capacity during atrophy such as in aged sarcopenia.-Hatazawa, Y., Ono, Y., Hirose, Y., Kanai, S., Fujii, N. L., Machida, S., Nishino, I., Shimizu, T., Okano, M., Kamei, Y., Ogawa, Y. Reduced Dnmt3a increases Gdf5 expression with suppressed satellite cell differentiation and impaired skeletal muscle regeneration.

    Full Text Available The emergence of urinary retention (UR, specifically acute urinary retention (AUR, has been a concern when treating men with lower urinary tract symptoms (LUTS with antimuscarinic drugs.In NEPTUNE (12-week, double-blind, men (≥45 years with LUTS were randomized to receive tamsulosin oral-controlled absorption system (TOCAS 0.4 mg, fixed-dose combination (FDC of solifenacin (Soli 6 mg + TOCAS 0.4 mg, FDC Soli 9 mg + TOCAS 0.4 mg, or placebo. In NEPTUNE II (40-week, open-label extension of NEPTUNE, continuing patients received 4-week FDC Soli 6 mg + TOCAS, then FDC Soli 6 mg or 9 mg + TOCAS for the remainder of the study, switchable every 3 months.Across both studies, 1208 men received ≥1 dose of FDC Soli 6 mg or 9 mg + TOCAS for up to 52 weeks; 1199 men completed NEPTUNE and 1066 received ≥1 dose in NEPTUNE II. In total, 13 men (1.1%; 95% CI, 0.6%-1.8% reported a UR event while receiving FDC, eight of which were AUR (0.7%; 95% CI, 0.3%-1.3%, incidence 7/1000 man-years. Six men reported UR events while taking Soli 6 mg + TOCAS (three AUR, and seven men reported a UR event while taking Soli 9 mg + TOCAS (five AUR. One man developed AUR while taking TOCAS alone and four reported UR (three AUR during placebo run-in. Most AUR/UR events occurred within 4 months of treatment initiation.FDC Soli and TOCAS was associated with a low rate of UR and AUR in men with LUTS.

  13. Maternal intravenous treatment with either azithromycin or solithromycin clears Ureaplasma parvum from the amniotic fluid in an ovine model of intrauterine infection. (United States)

    Intrauterine infection with Ureaplasma spp. is strongly associated with preterm birth and adverse neonatal outcomes. We assessed whether combined intraamniotic (IA) and maternal intravenous (IV) treatment with one of two candidate antibiotics, azithromycin (AZ) or solithromycin (SOLI), would eradicate intrauterine Ureaplasma parvum infection in a sheep model of pregnancy. Sheep with singleton pregnancies received an IA injection of U. parvum serovar 3 at 85 days of gestational age (GA). At 120 days of GA, animals (n=5 to 8/group) received one of the following treatments: (i) maternal IV SOLI with a single IA injection of vehicle (IV SOLI only); (ii) maternal IV SOLI with a single IA injection of SOLI (IV+IA SOLI); (iii) maternal IV AZ and a single IA injection of vehicle (IV AZ only); (iv) maternal IV AZ and a single IA injection of AZ (IV+IA AZ); or (v) maternal IV and single IA injection of vehicle (control). Lambs were surgically delivered at 125 days of GA. Treatment efficacies were assessed by U. parvum culture, quantitative PCR, enzyme-linked immunosorbent assay, and histopathology. Amniotic fluid (AF) from all control animals contained culturable U. parvum. AF, lung, and chorioamnion from all AZ- or SOLI-treated animals (IV only or IV plus IA) were negative for culturable U. parvum. Relative to the results for the control, the levels of expression of interleukin 1β (IL-1β), IL-6, IL-8, and monocyte chemoattractant protein 2 (MCP-2) in fetal skin were significantly decreased in the IV SOLI-only group, the MCP-1 protein concentration in the amniotic fluid was significantly increased in the IV+IA SOLI group, and there was no significant difference in the histological inflammation scoring of lung or chorioamnion among the five groups. In the present study, treatment with either AZ or SOLI (IV only or IV+IA) effectively eradicated macrolide-sensitive U. parvum from the AF. There was no discernible difference in antibiotic therapy efficacy between IV-only and IV

  5. The polymethyl methacrylate cervical cage for treatment of cervical disk disease Part III. Biomechanical properties. (United States)

    Chen, Jyi-Feng; Lee, Shih-Tseng


    In a previous article, we used the PMMA cervical cage in the treatment of single-level cervical disk disease and the preliminary clinical results were satisfactory. However, the mechanical properties of the PMMA cage were not clear. Therefore, we designed a comparative in vitro biomechanical study to determine the mechanical properties of the PMMA cage. The PMMA cervical cage and the Solis PEEK cervical cage were compressed in a materials testing machine to determine the mechanical properties. The compressive yield strength of the PMMA cage (7030 +/- 637 N) was less than that of the Solis polymer cervical cage (8100 +/- 572 N). The ultimate compressive strength of the PMMA cage (8160 +/- 724 N) was less than that of the Solis cage (9100 +/- 634 N). The stiffness of the PMMA cervical cage (8106 +/- 817 N/mm) was greater than that of the Solis cage (6486 +/- 530 N/mm). The elastic modulus of the PMMA cage (623 +/- 57 MPa) was greater than that of the Solis cage (510 +/- 42 MPa). The elongation of PMMA cage (43.5 +/- 5.7%) was larger than that of the Solis cage (36.1 +/- 4.3%). Although the compressive yield strength and ultimate compressive strength of the PMMA cervical cage were less than those of the Solis polymer cage, the mechanical properties are better than those of the cervical vertebral body. The PMMA cage is strong and safe for use as a spacer for cervical interbody fusion. Compared with other cage materials, the PMMA cage has many advantages and no obvious failings at present. However, the PMMA cervical cage warrants further long-term clinical study.

  6. Structural and functional dissection of differentially expressed tomato WRKY transcripts in host defense response against the vascular wilt pathogen (Fusarium oxysporum f. sp. lycopersici.

    Directory of Open Access Journals (Sweden)

    Mohd Aamir

    Full Text Available The WRKY transcription factors have indispensable role in plant growth, development and defense responses. The differential expression of WRKY genes following the stress conditions has been well demonstrated. We investigated the temporal and tissue-specific (root and leaf tissues differential expression of plant defense-related WRKY genes, following the infection of Fusarium oxysporum f. sp. lycopersici (Fol in tomato. The genome-wide computational analysis revealed that during the Fol infection in tomato, 16 different members of WRKY gene superfamily were found to be involved, of which only three WRKYs (SolyWRKY4, SolyWRKY33, and SolyWRKY37 were shown to have clear-cut differential gene expression. The quantitative real time PCR (qRT-PCR studies revealed different gene expression profile changes in tomato root and leaf tissues. In root tissues, infected with Fol, an increased expression for SolyWRKY33 (2.76 fold followed by SolyWRKY37 (1.93 fold gene was found at 24 hrs which further increased at 48 hrs (5.0 fold. In contrast, the leaf tissues, the expression was more pronounced at an earlier stage of infection (24 hrs.

    The WRKY transcription factors have indispensable role in plant growth, development and defense responses. The differential expression of WRKY genes following the stress conditions has been well demonstrated. We investigated the temporal and tissue-specific (root and leaf tissues) differential expression of plant defense-related WRKY genes, following the infection of Fusarium oxysporum f. sp. lycopersici (Fol) in tomato. The genome-wide computational analysis revealed that during the Fol infection in tomato, 16 different members of WRKY gene superfamily were found to be involved, of which only three WRKYs (SolyWRKY4, SolyWRKY33, and SolyWRKY37) were shown to have clear-cut differential gene expression. The quantitative real time PCR (qRT-PCR) studies revealed different gene expression profile changes in tomato root and leaf tissues. In root tissues, infected with Fol, an increased expression for SolyWRKY33 (2.76 fold) followed by SolyWRKY37 (1.93 fold) gene was found at 24 hrs which further increased at 48 hrs (5.0 fold). In contrast, the leaf tissues, the expression was more pronounced at an earlier stage of infection (24 hrs).

  15. Astrocyte IKKβ/NF-κB signaling is required for diet-induced obesity and hypothalamic inflammation

    Directory of Open Access Journals (Sweden)

    J.D. Douglass


    Full Text Available Objective: Obesity and high fat diet (HFD consumption in rodents is associated with hypothalamic inflammation and reactive gliosis. While neuronal inflammation promotes HFD-induced metabolic dysfunction, the role of astrocyte activation in susceptibility to hypothalamic inflammation and diet-induced obesity (DIO remains uncertain. Methods: Metabolic phenotyping, immunohistochemical analyses, and biochemical analyses were performed on HFD-fed mice with a tamoxifen-inducible astrocyte-specific knockout of IKKβ (GfapCreERIkbkbfl/fl, IKKβ-AKO, an essential cofactor of NF-κB-mediated inflammation. Results: IKKβ-AKO mice with tamoxifen-induced IKKβ deletion prior to HFD exposure showed equivalent HFD-induced weight gain and glucose intolerance as Ikbkbfl/fl littermate controls. In GfapCreERTdTomato marker mice treated using the same protocol, minimal Cre-mediated recombination was observed in the mediobasal hypothalamus (MBH. By contrast, mice pretreated with 6 weeks of HFD exposure prior to tamoxifen administration showed substantially increased recombination throughout the MBH. Remarkably, this treatment approach protected IKKβ-AKO mice from further weight gain through an immediate reduction of food intake and increase of energy expenditure. Astrocyte IKKβ deletion after HFD exposure—but not before—also reduced glucose intolerance and insulin resistance, likely as a consequence of lower adiposity. Finally, both hypothalamic inflammation and astrocytosis were reduced in HFD-fed IKKβ-AKO mice. Conclusions: These data support a requirement for astrocytic inflammatory signaling in HFD-induced hyperphagia and DIO susceptibility that may provide a novel target for obesity therapeutics.

  17. Systemic insulin sensitivity is regulated by GPS2 inhibition of AKT ubiquitination and activation in adipose tissue. (United States)

    Cederquist, Carly T; Lentucci, Claudia; Martinez-Calejman, Camila; Hayashi, Vanessa; Orofino, Joseph; Guertin, David; Fried, Susan K; Lee, Mi-Jeong; Cardamone, M Dafne; Perissi, Valentina


    Insulin signaling plays a unique role in the regulation of energy homeostasis and the impairment of insulin action is associated with altered lipid metabolism, obesity, and Type 2 Diabetes. The main aim of this study was to provide further insight into the regulatory mechanisms governing the insulin signaling pathway by investigating the role of non-proteolytic ubiquitination in insulin-mediated activation of AKT. The molecular mechanism of AKT regulation through ubiquitination is first dissected in vitro in 3T3-L1 preadipocytes and then validated in vivo using mice with adipo-specific deletion of GPS2, an endogenous inhibitor of Ubc13 activity (GPS2-AKO mice). Our results indicate that K63 ubiquitination is a critical component of AKT activation in the insulin signaling pathway and that counter-regulation of this step is provided by GPS2 preventing AKT ubiquitination through inhibition of Ubc13 enzymatic activity. Removal of this negative checkpoint, through GPS2 downregulation or genetic deletion, results in sustained activation of insulin signaling both in vitro and in vivo . As a result, the balance between lipid accumulation and utilization is shifted toward storage in the adipose tissue and GPS2-AKO mice become obese under normal laboratory chow diet. However, the adipose tissue of GPS2-AKO mice is not inflamed, the levels of circulating adiponectin are elevated, and systemic insulin sensitivity is overall improved. Our findings characterize a novel layer of regulation of the insulin signaling pathway based on non-proteolytic ubiquitination of AKT and define GPS2 as a previously unrecognized component of the insulin signaling cascade. In accordance with this role, we have shown that GPS2 presence in adipocytes modulates systemic metabolism by restricting the activation of insulin signaling during the fasted state, whereas in absence of GPS2, the adipose tissue is more efficient at lipid storage, and obesity becomes uncoupled from inflammation and insulin

  20. AMP-Activated Protein Kinase (AMPK) Regulates Energy Metabolism through Modulating Thermogenesis in Adipose Tissue (United States)

    Wu, Lingyan; Zhang, Lina; Li, Bohan; Jiang, Haowen; Duan, Yanan; Xie, Zhifu; Shuai, Lin; Li, Jia; Li, Jingya


    Obesity occurs when excess energy accumulates in white adipose tissue (WAT), whereas brown adipose tissue (BAT), which is specialized in dissipating energy through thermogenesis, potently counteracts obesity. White adipocytes can be converted to thermogenic “brown-like” cells (beige cells; WAT browning) under various stimuli, such as cold exposure. AMP-activated protein kinase (AMPK) is a crucial energy sensor that regulates energy metabolism in multiple tissues. However, the role of AMPK in adipose tissue function, especially in the WAT browning process, is not fully understood. To illuminate the effect of adipocyte AMPK on energy metabolism, we generated Adiponectin-Cre-driven adipose tissue-specific AMPK α1/α2 KO mice (AKO). These AKO mice were cold intolerant and their inguinal WAT displayed impaired mitochondrial integrity and biogenesis, and reduced expression of thermogenic markers upon cold exposure. High-fat-diet (HFD)-fed AKO mice exhibited increased adiposity and exacerbated hepatic steatosis and fibrosis and impaired glucose tolerance and insulin sensitivity. Meanwhile, energy expenditure and oxygen consumption were markedly decreased in the AKO mice both in basal conditions and after stimulation with a β3-adrenergic receptor agonist, CL 316,243. In contrast, we found that in HFD-fed obese mouse model, chronic AMPK activation by A-769662 protected against obesity and related metabolic dysfunction. A-769662 alleviated HFD-induced glucose intolerance and reduced body weight gain and WAT expansion. Notably, A-769662 increased energy expenditure and cold tolerance in HFD-fed mice. A-769662 treatment also induced the browning process in the inguinal fat depot of HFD-fed mice. Likewise, A-769662 enhanced thermogenesis in differentiated inguinal stromal vascular fraction (SVF) cells via AMPK signaling pathway. In summary, a lack of adipocyte AMPKα induced thermogenic impairment and obesity in response to cold and nutrient-overload, respectively

    Analysis of synoptic data from the Vector Stokes Magnetograph (VSM) of the Synoptic Optical Long-term Investigations of the Sun (SOLIS) and the NASA/NSO Spectromagnetograph (SPM) at the NSO/Kitt Peak Vacuum Telescope facility shows that the reversals of solar polar magnetic fields exhibit elements of a stochastic process, which may include the development of specific patterns of emerging magnetic flux, and the asymmetry in activity between northern and southern hemispheres. The presence of su...

  17. Citizen or Subordinate: Permutations of Belonging in the United States and the Dominican Republic

    Directory of Open Access Journals (Sweden)

    Shaina Aber


    Full Text Available The Dominican Republic and the United States have both experienced tensions arising from migratory flows from poorer, less stable neighbors. Until recently, both countries had constitutions which conferred citizenship by birth with very limited exceptions. Despite these similarities, their respective discourses around jus soli citizenship, particularly for the children of unauthorized migrants from the poorer neighboring countries, have manifested in different ways. The identity of the United States as a nation of immigrants has limited the success of campaigns to revoke jus soli citizenship for the children of unauthorized immigrants, but the persistent articulation of this idea as a response to illegal migration has shifted the parameters of the immigration debate. In the Dominican Republic, the historical construction of national identity and anti-Haitian discourse has led to an evolution in Dominican law which codifies already established practices that deny citizenship to children of Haitian migrants. In both cases, movements that support more inclusive understandings of societal belonging, like the DREAMers in the United States and youth movements in the Dominican Republic, may offer the most effective way of protecting universal jus soli citizenship regimes.

(United States)

    Tindall, B J


    In a recent publication the name Solimonadaceae Losey et al. 2013 has been proposed as a replacement name for the family name Sinobacteraceae Zhou et al. 2008. This course of action contravenes the current Code governing the nomenclature of prokaryotes, making Solimonadaceae Losey et al. 2013 an illegitimate name that neither has claim to priority nor can be used as a correct name. Closer examination of publications dealing with the taxonomy of members of the genera Solimonas and Sinobacter and the placement of these taxa at the rank of family and order reveal problems associated with the application of the family names Sinobacteraceae Zhou et al. 2008, Nevskiaceae Henrici and Johnson 1935 (Approved Lists 1980) and Lysobacteraceae Christensen and Cook 1978 (Approved Lists 1980) and the order names Lysobacterales Christensen and Cook 1978 (Approved Lists 1980) and Xanthomonadales Saddler and Bradbury 2005.

  19. Evaluation of the Orogenic Belt Hypothesis for the Formation of Thaumasia, Mars (United States)

    Nahm, A. L.; Schultz, R. A.


    The Thaumasia Highlands (TH) and Solis Planum are two of the best-known examples of compressional tectonics on Mars. The TH is a region of high topography located in the southern portion of the Tharsis Province, Mars. Solis Planum is located in eastern Thaumasia. Two hypotheses for the formation of this region have been suggested: sliding on a weak horizon or thrusting analogous to orogenic wedges on Earth. Both hypotheses require a shallowly dipping to sub-horizontal weak horizon below Thaumasia. Wrinkle ridges in Solis Planum are also inferred to sole into a décollement. If Thaumasia formed by thrusting related to sliding on a décollement, then certain conditions must be met as in critical taper wedge mechanics (CTWM) theory. If the angle between the surface slope and the basal décollement is less than predicted by the critical taper equation, the 'subcritical' wedge will deform internally until critical taper is achieved. Once the critical taper has been achieved, internal deformation ceases and the wedge will slide along its base. Formation of orogenic belts on Earth (such as the Central Mountains in Taiwan) can be described using CTWM. This method is applied here to the Thaumasia region on Mars. The surface slope (alpha) was measured in three locations: Syria Planum-Thaumasia margin, Solis Planum, and the TH. Topographic slopes were compared to the results from the critical taper equation. Because the dip of the basal décollement (beta) cannot be measured directly as on Earth, the dip angle was varied at 0 - 10 degrees; these values span the range of likely values based on terrestrial wedges. Pore fluid pressure (lambda) was varied between 0 (dry) and 0.9 (overpressured); these values span the full range of this important unknown parameter. Material properties, such as the coefficients of internal friction and of the basal décollement, were varied using reasonable values. Preliminary results show that for both reasonable (such as lambda = 0, mu b = 0

  1. Transcriptome of pancreas-specific Bmpr1a-deleted islets links to TPH1–5-HT axis

    Directory of Open Access Journals (Sweden)

    Fang-Xu Jiang


    Full Text Available Bone morphogenetic protein (BMP signaling is crucial for the development and function of numerous organs, but its role on the function of pancreatic islets is not completely clear. To explore this question, we applied the high throughput transcriptomic analyses on the islets isolated from mice with a pancreas-specific deletion of the gene, Bmpr1a, encoding the type 1a BMP receptor. Consistently, these pBmpr1aKO mice had impaired glucose homeostasis at 3 months, and were more severely affected at 12 months of age. These had lower fasting blood insulin concentrations, with reduced expression of several key regulators of β-cell function. Importantly, transcriptomic profiling of 3-month pBmpr1aKO islets and bioinformatic analyses revealed abnormal expression of 203 metabolic genes. Critically among these, the tryptophan hydroxylase 1 gene (Tph1, encoding the rate-limiting enzyme for the production of 5-hydroxytryptamine (5-HT was the highest over-expressed one. 5-HT is an important regulator of insulin secretion from β cells. Treatment with excess 5-HT inhibited this secretion. Thus our transcriptomic analysis links two highly conserved molecular pathways the BMP signaling and the TPH1–5-HT axis on glucose homeostasis.

  2. Effect of Acrocomia aculeata Kernel Oil on Adiposity in Type 2 Diabetic Rats. (United States)

    Nunes, Ângela A; Buccini, Danieli F; Jaques, Jeandre A S; Portugal, Luciane C; Guimarães, Rita C A; Favaro, Simone P; Caldas, Ruy A; Carvalho, Cristiano M E


    The macauba palm (Acrocomia aculeata) is native of tropical America and is found mostly in the Cerrados and Pantanal biomes. The fruits provide an oily pulp, rich in long chain fatty acids, and a kernel that encompass more than 50% of lipids rich in medium chain fatty acids (MCFA). Based on biochemical and nutritional evidences MCFA is readily catabolized and can reduce body fat accumulation. In this study, an animal model was employed to evaluate the effect of Acrocomia aculeata kernel oil (AKO) on the blood glucose level and the fatty acid deposit in the epididymal adipose tissue. The A. aculeata kernel oil obtained by cold pressing presented suitable quality as edible oil. Its fatty acid profile indicates high concentration of MCFA, mainly lauric, capric and caprilic. Type 2 diabetic rats fed with that kernel oil showed reduction of blood glucose level in comparison with the diabetic control group. Acrocomia aculeata kernel oil showed hypoglycemic effect. A small fraction of total dietary medium chain fatty acid was accumulated in the epididymal adipose tissue of rats fed with AKO at both low and high doses and caprilic acid did not deposit at all.

  3. Pharmacological Analysis of Vorinostat Analogues as Potential Anti-tumor Agents Targeting Human Histone Deacetylases: an Epigenetic Treatment Stratagem for Cancers. (United States)

    Praseetha, Sugathan; Bandaru, Srinivas; Nayarisseri, Anuraj; Sureshkumar, Sivanpillai


    Alteration of the acetylation status of chromatin and other non-histone proteins by HDAC inhibitors has evolved as an excellent epigenetic strategy in treatment of cancers. The present study was sought to identify compounds with positive pharmacological profiles targeting HDAC1. Analogues of Vorinostat synthesized by Cai et al, 2015 formed the test compounds for the present pharmacological evaluation. Hydroxamte analogue 6H showed superior pharmacological profile in comparison to all the compounds in the analogue dataset owing to its better electrostatic interactions and hydrogen bonding patterns. In order to identify compounds with even better high affinity and pharmacological profile than 6H and Vorinostat, virtual screening was performed. A total of 83 compounds similar to Vorinostat and 154 compounds akin to analogue 6H were retrieved. SCHEMBL15675695 (PubCid: 15739209) and AKOS019005527 (PubCid: 80442147) similar to Vorinostat and 6H, were the best docked compounds among the virtually screened compounds. However, in spite of having good affinity, none of the virtually screened compounds had better affinity than that of 6H. In addition SCHEMBL15675695 was predicted to be a carcinogen while AKOS019005527 is Ames toxic. From, our extensive analysis involving binding affinity analysis, ADMET properties predictions and pharmacophoric mappings, we report Vorinostat hydroxamate analogue 6H to be a potential candidate for HDAC inhibition in treatment of cancers through an epigenetic strategy.

    Directory of Open Access Journals (Sweden)

    Shin-ichi Hashimoto

    Full Text Available Massively parallel, tag-based sequencing systems, such as the SOLiD system, hold the promise of revolutionizing the study of whole genome gene expression due to the number of data points that can be generated in a simple and cost-effective manner. We describe the development of a 5'-end transcriptome workflow for the SOLiD system and demonstrate the advantages in sensitivity and dynamic range offered by this tag-based application over traditional approaches for the study of whole genome gene expression. 5'-end transcriptome analysis was used to study whole genome gene expression within a colon cancer cell line, HT-29, treated with the DNA methyltransferase inhibitor, 5-aza-2'-deoxycytidine (5Aza. More than 20 million 25-base 5'-end tags were obtained from untreated and 5Aza-treated cells and matched to sequences within the human genome. Seventy three percent of the mapped unique tags were associated with RefSeq cDNA sequences, corresponding to approximately 14,000 different protein-coding genes in this single cell type. The level of expression of these genes ranged from 0.02 to 4,704 transcripts per cell. The sensitivity of a single sequence run of the SOLiD platform was 100-1,000 fold greater than that observed from 5'end SAGE data generated from the analysis of 70,000 tags obtained by Sanger sequencing. The high-resolution 5'end gene expression profiling presented in this study will not only provide novel insight into the transcriptional machinery but should also serve as a basis for a better understanding of cell biology.

  9. Segmental kyphosis after cervical interbody fusion with stand-alone polyetheretherketone (PEEK) cages: a comparative study on 2 different PEEK cages. (United States)

    Kim, Chi Heon; Chung, Chun Kee; Jahng, Tae-Ahn; Park, Sung Bae; Sohn, Seil; Lee, Sungjoon


    Retrospective comparative study. Two polyetheretherketone (PEEK) cages of different designs were compared in terms of the postoperative segmental kyphosis after anterior cervical discectomy and fusion. Segmental kyphosis occasionally occurs after the use of a stand-alone cage for anterior cervical discectomy and fusion. Although PEEK material seems to have less risk of segmental kyphosis compared with other materials, the occurrence of segmental kyphosis for PEEK cages has been reported to be from 0% to 29%. There have been a few reports that addressed the issue of PEEK cage design. A total of 41 consecutive patients who underwent single-level anterior discectomy and fusion with a stand-alone cage were included. Either a round tube-type (Solis; 18 patients, S-group) or a trapezoidal tube-type (MC+; 23 patients, M-group) cage was used. The contact area between the cage and the vertebral body is larger in MC+ than in Solis, and anchoring pins were present in the Solis cage. The effect of the cage type on the segmental angle (SA) (lordosis vs. kyphosis) at postoperative month 24 was analyzed. Preoperatively, segmental lordosis was present in 12/18 S-group and 16/23 M-group patients (P=0.84). The SA was more lordotic than the preoperative angle in both groups just after surgery, with no difference between groups (P=0.39). At 24 months, segmental lordosis was observed in 9/18 S-group and 20/23 M-group patients (P=0.01). The patients in M-group were 7.83 times more likely than patients in S-group (P=0.04; odds ratio, 7.83; 95% confidence interval, 1.09-56.28) not to develop segmental kyphosis. The design of the PEEK cage used may influence the SA, and this association needs to be considered when using stand-alone PEEK cages.

  10. High-throughput sequencing of three Lemnoideae (duckweeds chloroplast genomes from total DNA.

    Directory of Open Access Journals (Sweden)

    Wenqin Wang

    Full Text Available BACKGROUND: Chloroplast genomes provide a wealth of information for evolutionary and population genetic studies. Chloroplasts play a particularly important role in the adaption for aquatic plants because they float on water and their major surface is exposed continuously to sunlight. The subfamily of Lemnoideae represents such a collection of aquatic species that because of photosynthesis represents one of the fastest growing plant species on earth. METHODS: We sequenced the chloroplast genomes from three different genera of Lemnoideae, Spirodela polyrhiza, Wolffiella lingulata and Wolffia australiana by high-throughput DNA sequencing of genomic DNA using the SOLiD platform. Unfractionated total DNA contains high copies of plastid DNA so that sequences from the nucleus and mitochondria can easily be filtered computationally. Remaining sequence reads were assembled into contiguous sequences (contigs using SOLiD software tools. Contigs were mapped to a reference genome of Lemna minor and gaps, selected by PCR, were sequenced on the ABI3730xl platform. CONCLUSIONS: This combinatorial approach yielded whole genomic contiguous sequences in a cost-effective manner. Over 1,000-time coverage of chloroplast from total DNA were reached by the SOLiD platform in a single spot on a quadrant slide without purification. Comparative analysis indicated that the chloroplast genome was conserved in gene number and organization with respect to the reference genome of L. minor. However, higher nucleotide substitution, abundant deletions and insertions occurred in non-coding regions of these genomes, indicating a greater genomic dynamics than expected from the comparison of other related species in the Pooideae. Noticeably, there was no transition bias over transversion in Lemnoideae. The data should have immediate applications in evolutionary biology and plant taxonomy with increased resolution and statistical power.

  11. The 'reformation' of counselling

    Directory of Open Access Journals (Sweden)

    G.A. Lotter


    Full Text Available Although the Reformation took place some four hundred years ago, one area in which reformation is really needed today is the counselling of people. Since Wilhelm Wundt started the “study of the mind” in 1879, William James and Sigmund Freud followed and secular psychology gradually has developed to take the “front seat”; hence moving Biblical counselling, which has been practised since the times of the New Testament, to the “back burner”. This development had been going on for the greater part of the 20th century, up to the publication of Competent to Counsel by Jay E. Adams in 1970. In the model for counselling suggested by Adams, the principles of the Reformation of the sixteenth century, Soli Deo Gloria, Soli Scriptura, Soli Fidei, Sola Gratia, etc. were again implemented in assisting and counselling people with personal and interpersonal problems. The epistomological and anthropological approach of secular psychology differs radically from that of Biblical principles, thus necessitating a new “reformation” of counselling. Within this new form counselling, inter alia, implies the following: the Word of God has its rightful place, sin has to be taken seriously and the work of the Holy Spirit should be recognised. In this article it is proposed that the “reformation” of counselling was started by scholars with a Biblical Reformational approach and that this method of counselling followed the parameters of the Reformation of the sixteenth century. This “reformation” developed into a new direction in counselling and still continues today with fascinating new frontiers opening up for Biblical counselling.

    Uchibayashi, Masao


    An etymological and semantic history of the terms of various pharmaceutical retailers in the West in presented. Apothecary is a combination of IE * apo- (separate) and * dhē (to place) which gave rise to the Greek term apothēkē, which originally meant a warehouse for food and wine. Pharmacy is a combination of the Greek term * pharama form IE * bher- (to charm, enchant) and -(a)-ko- resulting in * pharmako- (magic, charm, cure, potion, medicine) and in Latin pharmacie. Chemist's shop is the English version of an American drugstore. Further, such terms as dispensary, officinal and drug are etymologically discussed. Different usages in England and the U.S. of terms like shop and store are summarized. [Note:"IE" with asterisk stands for the Indo-European proto-languages which are the ancestors of most Western tongues.

  6. Vision system for dial gage torque wrench calibration (United States)

    Aggarwal, Neelam; Doiron, Theodore D.; Sanghera, Paramjeet S.


    In this paper, we present the development of a fast and robust vision system which, in conjunction with the Dial Gage Calibration system developed by AKO Inc., will be used by the U.S. Army in calibrating dial gage torque wrenches. The vision system detects the change in the angular position of the dial pointer in a dial gage. The angular change is proportional to the applied torque. The input to the system is a sequence of images of the torque wrench dial gage taken at different dial pointer positions. The system then reports the angular difference between the different positions. The primary components of this vision system include modules for image acquisition, linear feature extraction and angle measurements. For each of these modules, several techniques were evaluated and the most applicable one was selected. This system has numerous other applications like vision systems to read and calibrate analog instruments.

    We propose the idea of d-dot, where a d-wave superconducting dot is embedded in s-wave matrix. Spontaneous half vortices should appear in the four corners of the d-dot [M. Kato, M. Ako, M. Machida, T. Koyama, T. Ishida, Physica C 412-414 (2004) 352; M. Ako, M. Kato, M. Machida, T. Koyama, T. Ishida, Physica C 412-414 (2004) 544; M. Fujii, T. Abe, H. Yoshikawa, S. Miki, S. Kawamata, K.

Symmetric geometry and the fourfold symmetry of the d-dot would be suitable as a building block for constructing the novel physical systems. The phase dynamics of a closed 0-π junction, which can be realized in a small d x 2 -y 2 -dot, is mapped on a quantum two-level system when the system size is small enough. Using two-component Ginzburg-Landau equation, we study the physical properties of d-dots systematically. We prepare epitaxial YBa 2 Cu 3 O 7 (YBCO) films of thickness 100nm on SrTiO 3 substrates using a laser ablation apparatus. The d-dot is fabricated by a photolithography, electron beam lithography EB and an electron cyclotron resonance (ECR) etching, a focused ion beam microscope, and a lift-off technique. Local vortex profile is investigated using a SQUID microscope when d-dot is cooled in zero field

Pravo vaditi podrtinu ili potonulu stvar primarno ima njezin vlasnik odnosno ovlaštena osoba. Zakon vlasnicima podrtina i potonulih stvari, odnosno ovlaštenim osobama, ostavlja primjeren rok u kojem mogu pokrenuti upravni postupak za dobivanje dozvole za vađenje podrtine ili potonule stvari. Na taj način jamči se nepovredivost vlasništva i utvrđuje načelo prema kojem činjenica da je stvar potonula ili se nasukala ne utječe izravno na vlasnička prava njezina dotadašnjeg vlasnika. Međutim, ako vlasnik, odnosno ovlaštena osoba ne zatraži odobrenje za vađenje podrtine ili potonule stvari, ili kad bez opravdanog razloga prekine ili napusti započeto vađenje kao i u slučaju ako je ovlaštena osoba nepoznata, PZ nudi pravni okvir i omogućuje da vađenje podrtine ili potonule stvari poduzme pošteni nalaznik ili lučka kapetanija.

    MALINA is a web service for bioinformatic analysis of whole-genome metagenomic data obtained from human gut microbiota sequencing. As input data, it accepts metagenomic reads of various sequencing technologies, including long reads (such as Sanger and 454 sequencing) and next-generation (including SOLiD and Illumina). It is the first metagenomic web service that is capable of processing SOLiD color-space reads, to authors' knowledge. The web service allows phylogenetic and functional profiling of metagenomic samples using coverage depth resulting from the alignment of the reads to the catalogue of reference sequences which are built into the pipeline and contain prevalent microbial genomes and genes of human gut microbiota. The obtained metagenomic composition vectors are processed by the statistical analysis and visualization module containing methods for clustering, dimension reduction and group comparison. Additionally, the MALINA database includes vectors of bacterial and functional composition for human gut microbiota samples from a large number of existing studies allowing their comparative analysis together with user samples, namely datasets from Russian Metagenome project, MetaHIT and Human Microbiome Project (downloaded from MALINA is made freely available on the web at The website is implemented in JavaScript (using Ext JS), Microsoft .NET Framework, MS SQL, Python, with all major browsers supported.

  17. The role of measured data in a free natural gas market

    International Nuclear Information System (INIS)

    Ter Horst, G.J.P.; Fransen, T.


    As from 2002 medium-scale customers connected to the distribution network of the regional natural gas distribution companies will be able to purchase their gas from third parties. In order to calculate the energy (gas) transmission, distribution and supply costs, it is necessary to measure and record the offtakes of all the customers with freedom of choice on an hourly basis. The Dutch natural gas trading company Gasunie usually carries out these measurements for the present 350 medium-scale customers, but for the 14,000 customers by 2002 a different solution probably must be chosen. This is because most offtakes do not have any provision for measuring consumption on an hourly basis. Following the electricity market, offtake profiles will be prepared for most customers. If the parties cannot reach agreement on those profiles, expensive measuring equipment has to be installed on site. The Standard Online Information Server (Solis) is used in a project to transfer the data measured online from a remote customer to the electricity supplier. Solis will also be used for transferring gas data. The Dutch natural gas research institute Gastec has carried out a definition study into the use of gas consumption profiles for assessing the gas balance. Gastec and KEMA (research institute for the Dutch electric power companies) will jointly further develop this gas consumption model for both the gas and electricity market

  18. High-Throughput Sequencing of MicroRNAs in Adenovirus Type 3 Infected Human Laryngeal Epithelial Cells

    Directory of Open Access Journals (Sweden)

    Yuhua Qi


    Full Text Available Adenovirus infection can cause various illnesses depending on the infecting serotype, such as gastroenteritis, conjunctivitis, cystitis, and rash illness, but the infection mechanism is still unknown. MicroRNAs (miRNA have been reported to play essential roles in cell proliferation, cell differentiation, and pathogenesis of human diseases including viral infections. We analyzed the miRNA expression profiles from adenovirus type 3 (AD3 infected Human laryngeal epithelial (Hep2 cells using a SOLiD deep sequencing. 492 precursor miRNAs were identified in the AD3 infected Hep2 cells, and 540 precursor miRNAs were identified in the control. A total of 44 miRNAs demonstrated high expression and 36 miRNAs showed lower expression in the AD3 infected cells than control. The biogenesis of miRNAs has been analyzed, and some of the SOLiD results were confirmed by Quantitative PCR analysis. The present studies may provide a useful clue for the biological function research into AD3 infection.

  19. Cyber threat impact assessment and analysis for space vehicle architectures (United States)

    McGraw, Robert M.; Fowler, Mark J.; Umphress, David; MacDonald, Richard A.


    This paper covers research into an assessment of potential impacts and techniques to detect and mitigate cyber attacks that affect the networks and control systems of space vehicles. Such systems, if subverted by malicious insiders, external hackers and/or supply chain threats, can be controlled in a manner to cause physical damage to the space platforms. Similar attacks on Earth-borne cyber physical systems include the Shamoon, Duqu, Flame and Stuxnet exploits. These have been used to bring down foreign power generation and refining systems. This paper discusses the potential impacts of similar cyber attacks on space-based platforms through the use of simulation models, including custom models developed in Python using SimPy and commercial SATCOM analysis tools, as an example STK/SOLIS. The paper discusses the architecture and fidelity of the simulation model that has been developed for performing the impact assessment. The paper walks through the application of an attack vector at the subsystem level and how it affects the control and orientation of the space vehicle. SimPy is used to model and extract raw impact data at the bus level, while STK/SOLIS is used to extract raw impact data at the subsystem level and to visually display the effect on the physical plant of the space vehicle.

    Short-term trials have demonstrated the efficacy and safety of combination therapy using antimuscarinics and α-blockers in men with lower urinary tract symptoms (LUTS). The Study of Solifenacin Succinate and Tamsulosin Hydrochloride OCAS (oral controlled absorption system) in Males with Lower Urinary Tract Symptoms (NEPTUNE) II is the first long-term study using solifenacin (Soli) and the oral controlled absorption system formulation of tamsulosin (TOCAS). To evaluate long-term (up to 52 wk) safety and efficacy of flexible dosing of two fixed-dose combinations (FDC) of Soli plus TOCAS in men with moderate to severe storage symptoms and voiding symptoms. Patients with both storage and voiding LUTS, maximum urinary flow rate of 4.0-12.0 ml/s, prostate size storage and voiding subscores, micturition diary variables, and quality of life parameters. In all, 1066 men completed NEPTUNE and received one dose or more of study medication in NEPTUNE II. Treatment-emergent adverse events were reported in 499 (46.8%) patients who participated in NEPTUNE II; most were mild or moderate. Urinary retention occurred in 13 of 1208 (1.1%) patients receiving one or more FDCs in NEPTUNE and/or NEPTUNE II; 8 (0.7%) required catheterisation (acute urinary retention [AUR]). Reductions in total IPSS and TUFS during NEPTUNE were maintained for up to 52 wk of FDC treatment, with mean reductions of 9.0 (standard deviation [SD]: 5.7) and 10.1 (SD: 9.2), respectively, from baseline to end of treatment. Clinically relevant improvements were also observed for secondary efficacy end points. Long-term treatment with FDC Soli plus TOCAS was well tolerated and efficacious in men with storage and voiding LUTS, with a low incidence of AUR. Treatment with solifenacin plus tamsulosin in a fixed-dose combination tablet was well tolerated by men with lower urinary tract symptoms. Improvements in symptoms were achieved after 4 wk of treatment, with further improvements at week 16 maintained for up to 52 wk

  1. Effects of short-term exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin on microRNA expression in zebrafish embryos

    Although many drugs and environmental chemicals are teratogenic, the mechanisms by which most toxicants disrupt embryonic development are not well understood. MicroRNAs, single-stranded RNA molecules of ∼ 22 nt that regulate protein expression by inhibiting mRNA translation and promoting mRNA sequestration or degradation, are important regulators of a variety of cellular processes including embryonic development and cellular differentiation. Recent studies have demonstrated that exposure to xenobiotics can alter microRNA expression and contribute to the mechanisms by which environmental chemicals disrupt embryonic development. In this study we tested the hypothesis that developmental exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), a well-known teratogen, alters microRNA expression during zebrafish development. We exposed zebrafish embryos to DMSO (0.1%) or TCDD (5 nM) for 1 h at 30 hours post fertilization (hpf) and measured microRNA expression using several methods at 36 and 60 hpf. TCDD caused strong induction of CYP1A at 36 hpf (62-fold) and 60 hpf (135-fold) as determined by real-time RT-PCR, verifying the effectiveness of the exposure. MicroRNA expression profiles were determined using microarrays (Agilent and Exiqon), next-generation sequencing (SOLiD), and real-time RT-PCR. The two microarray platforms yielded results that were similar but not identical; both showed significant changes in expression of miR-451, 23a, 23b, 24 and 27e at 60 hpf. Multiple analyses were performed on the SOLiD sequences yielding a total of 16 microRNAs as differentially expressed by TCDD in zebrafish embryos. However, miR-27e was the only microRNA to be identified as differentially expressed by all three methods (both microarrays, SOLiD sequencing, and real-time RT-PCR). These results suggest that TCDD exposure causes modest changes in expression of microRNAs, including some (miR-451, 23a, 23b, 24 and 27e) that are critical for hematopoiesis and cardiovascular

  3. Ablation of an Ovarian Tumor Family Deubiquitinase Exposes the Underlying Regulation Governing the Plasticity of Cell Cycle Progression in Toxoplasma gondii. (United States)

    Dhara, Animesh; de Paula Baptista, Rodrigo; Kissinger, Jessica C; Snow, E Charles; Sinai, Anthony P


    The Toxoplasma genome encodes the capacity for distinct architectures underlying cell cycle progression in a life cycle stage-dependent manner. Replication in intermediate hosts occurs by endodyogeny, whereas a hybrid of schizogony and endopolygeny occurs in the gut of the definitive feline host. Here, we characterize the consequence of the loss of a cell cycle-regulated o varian tu mor (OTU family) deubiquitinase, OTUD3A of Toxoplasma gondii (TgOTUD3A; TGGT1_258780), in T. gondii tachyzoites. Rather than the mutation being detrimental, mutant parasites exhibited a fitness advantage, outcompeting the wild type. This phenotype was due to roughly one-third of TgOTUD3A-knockout (TgOTUD3A-KO) tachyzoites exhibiting deviations from endodyogeny by employing replication strategies that produced 3, 4, or 5 viable progeny within a gravid mother instead of the usual 2. We established the mechanistic basis underlying these altered replication strategies to be a dysregulation of centrosome duplication, causing a transient loss of stoichiometry between the inner and outer cores that resulted in a failure to terminate S phase at the attainment of 2N ploidy and/or the decoupling of mitosis and cytokinesis. The resulting dysregulation manifested as deviations in the normal transitions from S phase to mitosis (S/M) (endopolygeny-like) or M phase to cytokinesis (M/C) (schizogony-like). Notably, these imbalances are corrected prior to cytokinesis, resulting in the generation of normal progeny. Our findings suggest that decisions regarding the utilization of specific cell cycle architectures are controlled by a ubiquitin-mediated mechanism that is dependent on the absolute threshold levels of an as-yet-unknown target(s). Analysis of the TgOTUD3A-KO mutant provides new insights into mechanisms underlying the plasticity of apicomplexan cell cycle architecture. IMPORTANCE Replication by Toxoplasma gondii can occur by 3 distinct cell cycle architectures. Endodyogeny is used by asexual

    A study on the use of gamma radiation in the induction of mutations in eight varieties of soybean was conducted. The radiosensitivity of the seeds of both local and introduced soybean varieties was determined. The effects of gamma radiation in the M1 generation were evaluated. Percentage germination was not affected by doses of 200 and 250 Gy gamma radiation in all the eight soybean varieties. No significant differences in seedling height were observed at 200 Gy and the control except for the 250 Gy in BPI-Sy4, PSB-Sy4 and PSB-Sy5. In the Vietnamese varieties, significant differences in seedling height were obtained in doses of 200, 250 Gy and the control except for the variety AKO 6. There was significant difference in plant height of mature plants between the control and treatment dose of 250 Gy in varieties DT 95 and AKO 6. Likewise, significant differences in mature plant height were noted between the control and those at 250 Gy in local varieties BPI-Sy4, PSB-Sy5 and NSIC-Sy8. The number of days to flower was not affected by gamma radiation in both the local and introduced varieties. There were significant differences in the number of pods per plant between the control and a low dose of 200 Gy in Vietnamese variety DT 96 and the local varieties PSB-Sy4, PSB-Sy5 and NSIC-Sy8. The 3 types of chlorophyll mutation induced by gamma rays in the local varieties were: chlorina, striatia,and spotted yellow. Only chlorina mutant was induced in the introduced varieties. Desirable mutants that are early and high yielding were selected. Results of the drought tolerance tests indicated that the number of days to flowering of the control and 8 varieties was not affected by the duration of irrigation withdrawals 20,30,40 and 50 days after planting. Significant differences in seed weight among the different varieties were noted only in 20 and 30 day irrigation withdrawal treatment. When the effects of the different treatments were analyzed on a per variety bases, some of the

  5. Bone regeneration in critical bone defects using three-dimensionally printed β-tricalcium phosphate/hydroxyapatite scaffolds is enhanced by coating scaffolds with either dipyridamole or BMP-2. (United States)

    Ishack, Stephanie; Mediero, Aranzazu; Wilder, Tuere; Ricci, John L; Cronstein, Bruce N


    Bone defects resulting from trauma or infection need timely and effective treatments to restore damaged bone. Using specialized three-dimensional (3D) printing technology we have created custom 3D scaffolds of hydroxyapatite (HA)/beta-tri-calcium phosphate (β-TCP) to promote bone repair. To further enhance bone regeneration we have coated the scaffolds with dipyridamole, an agent that increases local adenosine levels by blocking cellular uptake of adenosine. Nearly 15% HA:85% β-TCP scaffolds were designed using Robocad software, fabricated using a 3D Robocasting system, and sintered at 1100°C for 4 h. Scaffolds were coated with BMP-2 (200 ng mL -1 ), dypiridamole 100 µM or saline and implanted in C57B6 and adenosine A2A receptor knockout (A2AKO) mice with 3 mm cranial critical bone defects for 2-8 weeks. Dipyridamole release from scaffold was assayed spectrophotometrically. MicroCT and histological analysis were performed. Micro-computed tomography (microCT) showed significant bone formation and remodeling in HA/β-TCP-dipyridamole and HA/β-TCP-BMP-2 scaffolds when compared to scaffolds immersed in vehicle at 2, 4, and 8 weeks (n = 5 per group; p ≤ 0.05, p ≤ 0.05, and p ≤ 0.01, respectively). Histological analysis showed increased bone formation and a trend toward increased remodeling in HA/β-TCP- dipyridamole and HA/β-TCP-BMP-2 scaffolds. Coating scaffolds with dipyridamole did not enhance bone regeneration in A2AKO mice. In conclusion, scaffolds printed with HA/β-TCP promote bone regeneration in critical bone defects and coating these scaffolds with agents that stimulate A2A receptors and growth factors can further enhance bone regeneration. These coated scaffolds may be very useful for treating critical bone defects due to trauma, infection or other causes. © 2015 Wiley Periodicals, Inc.

  6. Afferent input selects NMDA receptor subtype to determine the persistency of hippocampal LTP in freely behaving mice

    Directory of Open Access Journals (Sweden)

    Jesús Javier Ballesteros


    Full Text Available The glutamatergic N-methyl-D-aspartate receptor (NMDAR is critically involved in many forms of hippocampus-dependent memory that may be enabled by synaptic plasticity. Behavioral studies with NMDAR antagonists and NMDAR subunit (GluN2 mutants revealed distinct contributions from GluN2A- and GluN2B-containing NMDARs to rapidly and slowly acquired memory performance. Furthermore, studies of synaptic plasticity, in genetically modified mice in vitro, suggest that GluN2A and GluN2B may contribute in different ways to the induction and longevity of synaptic plasticity. In contrast to the hippocampal slice preparation, in behaving mice, the afferent frequencies that induce synaptic plasticity are very restricted and specific. In fact, it is the stimulus pattern, and not variations in afferent frequency that determine the longevity of long-term potentiation (LTP. Here, we explored the contribution of GluN2A and GluN2B to LTP of differing magnitudes and persistencies in freely behaving mice. We applied differing high-frequency stimulation (HFS patterns at 100 Hz to the hippocampal CA1 region, to induce NMDAR-dependent LTP in wild-type (WT mice, that endured for 24h (late (L-LTP. In GluN2A-KO mice, E-LTP (HFS, 50 pulses was significantly reduced in magnitude and duration, whereas LTP (HFS, 2 x 50 pulses and L-LTP (HFS, 4 x 50 pulses were unaffected compared to responses in WT animals. By contrast, pharmacological antagonism of GluN2B in WT had no effect on E-LTP but significantly prevented LTP. E- LTP and LTP were significantly impaired by GluN2B antagonism in GluN2A-KO mice. These data indicate that the pattern of afferent stimulation is decisive for the recruitment of distinct GluN2A and GluN2B signaling pathways that in turn determine the persistency of hippocampal LTP. Whereas brief bursts of patterned stimulation preferentially recruit GluN2A and lead to weak and short-lived forms of LTP, prolonged, more intense, afferent activation recruits GluN2B

  8. Is there radar evidence for liquid water on Mars? (United States)

    Roth, L. E.


    The hypothesis that an extraordinary radar smoothness of a lunar target suggests that ground moisture is rest on the assumption that on the penetration-depth scale, the dielectric constant be an isotropic quantity. In other words, the planet's surface should have no vertical structure. Results of modeling exercises (based on the early lunar two-layer models) conducted to simulate the behavior of radar reflectivity, at S-band, over Solis Lacus, without manipulating the dielectric constant of the base layer (i.e., without adding moisture) are summarized. More sophisticated, explicit, rather than iterative multi-layer models involving dust, duricrust, mollisol, and permafrost are under study. It is anticipated that a paradoxical situation will be reached when each improvement in the model introduces additional ambiguities into the data interpretation.

    We have recently found that multiple rare variants of the glucocerebrosidase gene (GBA) confer a robust risk for Parkinson disease, supporting the 'common disease-multiple rare variants' hypothesis. To develop an efficient method of identifying rare variants in a large number of samples, we applied multiplexed resequencing using a next-generation sequencer to identification of rare variants of GBA. Sixteen sets of pooled DNAs from six pooled DNA samples were prepared. Each set of pooled DNAs was subjected to polymerase chain reaction to amplify the target gene (GBA) covering 6.5 kb, pooled into one tube with barcode indexing, and then subjected to extensive sequence analysis using the SOLiD System. Individual samples were also subjected to direct nucleotide sequence analysis. With the optimization of data processing, we were able to extract all the variants from 96 samples with acceptable rates of false-positive single-nucleotide variants.

    Il genio di Werner Heisenberg attraversa l'orizzonte della fisica del nostro secolo come una meteora. Testimoniano della fecondità e dell'originalità del suo pensiero non solo il Nobel che gli fu assegnato a soli 32 anni, ma soprattutto i decisivi impulsi da lui dati alla fisica quantistica, alla teoria delle particelle elementari, alla teoria del nucleo. Si deve a Heisenberg quel "principio di indeterminazione" che ha rivoluzionato non solo il corso della fisica ma il modo di concepire la posizione dell'uomo nell'universo. L'interesse del libro, però, vuole andare oltre la fisica, giacché il curriculum del "ragazzo di campagna dei biondi capelli" rispecchia in forma emblematica l'ambiguo rapporto della scienza col potere.

    The few prethaw observations of tundra carbon fluxes suggest that there may be large spring releases, but little Is lmown about the scale and underlying mechanisms of this phenomenon. To address these questions, we combined ecosystem eddy flux measurements from two towers near Barrow, Alaska, with mechanistic soil-core thawing experiment During a 2week period prior to snowmelt In 2014, large fluxes were measured, reducing net summer uptake of CO2 by 46% and adding 6% to cumulative CH4 emissions. Emission pulses were linked to unique rain-on-snow events enhancing soli cracking. Controlled laboratory experiment revealed that as surface Ice thaws, an immediate, large pulse of trapped gases Is emitted. These results suggest that the Arctic C02 and CH4 spring pulse is a delayed release of biogenic gas production from the previous fall and that the pulse can be large enough to offset a significant fraction of the moderate Arctic tundra carbon sink.

    Xiaoming Zhang


    Full Text Available Inspired by the transmission of beans in nature, a novel evolutionary algorithm-Bean Optimization Algorithm (BOA is proposed in this paper. BOA is mainly based on the normal distribution which is an important continuous probability distribution of quantitative phenomena. Through simulating the self-adaptive phenomena of plant, BOA is designed for solving continuous optimization problems. We also analyze the global convergence of BOA by using the Solis and Wetsarsquo; research results. The conclusion is that BOA can converge to the global optimization solution with probability one. In order to validate its effectiveness, BOA is tested against benchmark functions. And its performance is also compared with that of particle swarm optimization (PSO algorithm. The experimental results show that BOA has competitive performance to PSO in terms of accuracy and convergence speed on the explored tests and stands out as a promising alternative to existing optimization methods for engineering designs or applications.

  15. A new ion source for fission-yield measurements of rare-earth isotopes

    International Nuclear Information System (INIS)

    Pilzer, E.H.; Engler, G.


    A new integrated target-ion source for fission-yield measurements of rare-earth isotopes has been developed for the Soreq on-line isotope separator (SOLIS). The source is heated by electron bombardment to a temperature of 2400 0 C and ionization takes place in a rhenium hot cavity. To overcome the problem of impurities which reduce the ionization efficiency, a ZrC disk was inserted in the cavity. Calculations show that because of its high thermionic emission, ZrC enhances ionization performance considerably. For example, in the presence of 10 -5 mbar of cesium impurity, the ionization efficiency of a rhenium hot cavity for the rare-earth terbium is 6%. However, with a ZrC disk, the efficiency increases to 97%. (orig.)

  17. Orientation of coronal bright points and small-scale magnetic bipoles

    International Nuclear Information System (INIS)



    Using the observations from Extreme-Ultraviolet Imaging Telescope (EIT) on the SOHO board and longitudinal full-disk magnetograms (vector spectromagnetograph - VSM) from the Synoptic Optical Long-Term Investigations of the Sun (SOLIS), we explore the orientation and relationship between the coronal bright points at 195 A o (hereafter CBPs) and magnetic bipoles (only for the central zone of solar disk). The magnetic bipoles are identified as a pair of streams of positive and negative polarities with a shortest distance between them. This paper presents a study of the structure and orientation (angles) of magnetic bipoles to the solar equator and two types of CBPs: 'dim' CBPs in the quiet regions of the Sun and 'bright' CBPs associated with active regions. For these magnetic bipoles associated with 'bright' CBPs, we find that their orientation angles are distributed randomly along the equator. (authors)

  19. What If We Had A Magnetograph at Lagrangian L5? (United States)

    Pevtsov, Alexei A.; Bertello, Luca; MacNeice, Peter; Petrie, Gordon


    Synoptic Carrington charts of magnetic field are routinely used as an input for modelings of solar wind and other aspects of space weather forecast. However, these maps are constructed using only the observations from the solar hemisphere facing Earth. The evolution of magnetic flux on the "farside" of the Sun, which may affect the topology of coronal field in the "nearside," is largely ignored. It is commonly accepted that placing a magnetograph in Lagrangian L5 point would improve the space weather forecast. However, the quantitative estimates of anticipated improvements have been lacking. We use longitudinal magnetograms from the Synoptic Optical Long-term Investigations of the Sun (SOLIS) to investigate how adding data from L5 point would affect the outcome of two major models used in space weather forecast.

    A subset of KIT/PDGFRA wild-type gastrointestinal stromal tumors (WT GIST) have been associated with alteration of the succinate dehydrogenase (SDH) complex II function. A recent report identified four non-syndromic, KIT/PDGFRA WT GIST harboring compound heterozygous or homozygous mutations in SDHA encoding the main subunit of the SDH complex II. Next generation sequencing was applied on five pediatric and one young adult WT GIST, by whole exome capture and SOLiD 3-plus system sequencing. The putative mutations were first confirmed by Sanger sequencing and then screened on a larger panel of 11 pediatric and young adult WT GIST, including 5 in the context of Carney triad. A germline p.Arg31X nonsense SDHA mutation was identified in one of the six cases tested by SOLiD platform. An additional p.D38V missense mutation in SDHA exon 2 was identified by Sanger sequencing in the extended KIT/PDGFRA WT GIST patients cohort. Western blotting showed loss of SDHA expression in the two cases harboring SDHA mutations, while expression being retained in the other WT GIST tumors. Results were further confirmed by immunohistochemistry for both SDHA and SDHB, which showed a concurrent loss of expression of both proteins in SDHA-mutant lesions, while the remaining WT tumors showed only loss of SDHB expression. Germline and/or somatic aberrations of SDHA occur in a small subset of KIT/PDGFRA WT GISTs, outside the Carney’s triad and are associated with loss of both SDHA and SDHB protein expression. Mutations of the SDH complex II are more particularly associated with KIT/PDGFRA WT GIST occurring in young adults. Although pediatric GIST consistently display alterations of SDHB protein expression, further molecular studies are needed to identify the crucial genes involved in their tumorigenesis

    Cheng, Juan; Chen, Wei; Huo-Zhang, Bing; Nimaichand, Salam; Zhou, En-Min; Lu, Xin-Hua; Klenk, Hans-Peter; Li, Wen-Jun


    A Gram-positive, coccoid, non-endospore-forming actinobacterium, designated YIM C01117(T), was isolated from a soil sample collected from Alu ancient cave, Yunnan province, south-west China. Based on the 16S rRNA gene sequence analysis, strain YIM C01117(T) was shown to belong to the genus Microlunatus, with highest sequence similarity of 97.4 % to Microlunatus soli DSM 21800(T). The whole genomic DNA relatedness as shown by the DNA-DNA hybridization study between YIM C01117(T) and M. soli DSM 21800(T) had a low value (47 ± 2 %). Strain YIM C01117(T) was determined to contain LL-diaminopimelic acid with Gly, Glu and Ala amino acids (A3γ' type) in the cell wall. Whole-cell hydrolysates were found to contain glucose, galactose, mannose and ribose. The major polar lipids were determined to be phosphatidylglycerol and diphosphatidylglycerol. The predominant menaquinone system present is MK-9(H4), while the major fatty acids were identified to be anteiso-C15:0 (24.1 %), iso-C16:0 (22.3 %) and iso-C15:0 (11.4 %). The G+C content of the genomic DNA was determined to be 65.9 mol%. The chemotaxonomic and genotypic data support the affiliation of the strain YIM C01117(T) to the genus Microlunatus. The results of physiological and biochemical tests allow strain YIM C01117(T) to be differentiated phenotypically from recognized Microlunatus species. Strain YIM C01117(T) is therefore considered to represent a novel species of the genus Microlunatus, for which the name Microlunatus cavernae sp. nov. is proposed. The type strain is YIM C01117(T) (= DSM 26248(T) = JCM 18536(T)).

    Kim, Soo-Jin; Kim, Yi-Seul; Weon, Hang-Yeon; Anandham, Rangasamy; Noh, Hyung-Jun; Kwon, Soon-Wo


    A novel aerobic, Gram-negative, motile, rod-shaped bacterial strain designated 5516S-2(T) was isolated from an air sample taken in Suwon, Republic of Korea. Colonies were yellow-pigmented and circular with entire margins. 16S rRNA gene sequence analysis showed that strain 5516S-2(T) was closely related to Xylophilus ampelinus DSM 7250(T) (97.6 % sequence similarity), Variovorax soli KACC 11579(T) (97.5 %) and Xenophilus azovorans DSM 13620(T) (97.1 %). However, the phylogenetic tree indicated that strain 5516S-2(T) formed a separate clade from Xenophilus azovorans. Strain 5516S-2(T) displayed 42, 31 and 30 % DNA-DNA relatedness to the type strains of Xenophilus azovorans, Xylophilus ampelinus and V. soli, respectively. The major fatty acids (>10 % of total fatty acids) were C(16 : 0) (33.3 %), C(17 : 0) cyclo (18.8 %), C(18 : 1)omega7c (17.5 %) and summed feature 3 (comprising C(16 : 1)omega7c and/or iso-C(15 : 0) 2-OH; 13.0 %). The DNA G+C content was 69 mol%. The major quinone was ubiquinone Q-8. The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and two unknown aminophospholipids. Genotypic and phenotypic characteristics clearly distinguished strain 5516S-2(T) from closely related species and indicated that it represents a novel species within the genus Xenophilus, for which the name Xenophilus aerolatus sp. nov. is proposed. The type strain is 5516S-2(T) (=KACC 12602(T)=DSM 19424(T)).

    A Dehalococcoides-containing bacterial consortium that performed dechlorination of 0.20 mM cis-1,2-dichloroethene to ethene in 14 days was obtained from the sediment mud of the lotus field. To obtain detailed information of the consortium, the metagenome was analyzed using the short-read next-generation sequencer SOLiD 3. Matching the obtained sequence tags with the reference genome sequences indicated that the Dehalococcoides sp. in the consortium was highly homologous to Dehalococcoides mccartyi CBDB1 and BAV1. Sequence comparison with the reference sequence constructed from 16S rRNA gene sequences in a public database showed the presence of Sedimentibacter, Sulfurospirillum, Clostridium, Desulfovibrio, Parabacteroides, Alistipes, Eubacterium, Peptostreptococcus and Proteocatella in addition to Dehalococcoides sp. After further enrichment, the members of the consortium were narrowed down to almost three species. Finally, the full-length circular genome sequence of the Dehalococcoides sp. in the consortium, D. mccartyi IBARAKI, was determined by analyzing the metagenome with the single-molecule DNA sequencer PacBio RS. The accuracy of the sequence was confirmed by matching it to the tag sequences obtained by SOLiD 3. The genome is 1,451,062 nt and the number of CDS is 1566, which includes 3 rRNA genes and 47 tRNA genes. There exist twenty-eight RDase genes that are accompanied by the genes for anchor proteins. The genome exhibits significant sequence identity with other Dehalococcoides spp. throughout the genome, but there exists significant difference in the distribution RDase genes. The combination of a short-read next-generation DNA sequencer and a long-read single-molecule DNA sequencer gives detailed information of a bacterial consortium.

    During 1980 the activities of RA reactor staff was conducted in two directions: repair works and determination of the state of the existing equipment; and preparing and constructing additional equipment and completing the documentation needed to fulfill the new legal regulations. preparation of the existing equipment for future operation was finished, but construction of the additional equipment (according to the regulations) is not done at planned rate due to different reasons such as lack of budget, administration, import. This report includes a chapter devoted to the analysis of the operation difficulties that caused prohibition of reactor operation as well as difficulties in achievement of the planned activities for 1980. Data about financial issues are included as well. [Serbo-Croat] U toku 1980. godine rad OOUR-a Nuklearni reaktor RA odvijao se u dva smera: remontnim radovima i utvrdjivanju stanja postojece opreme i u pripremi i ugradnji potrebne dodatne opreme i kompletiranju neophodne dokumentacije prema novim zakonskim propisima. Priprema postojece opreme za rad je u potpunosti izvrsena, dok se projekti i ugradnja dodatne opreme (prema zakonskim obavezama) ne odvija potrebnom brzinom zbog raznih objektivnih razloga, kao nedostatak sredstava, odobrenja, uvoza. Ovaj izvestaj sadrzi poglavlje posveceno analizi teskoca u radu koje su dovele do zabrane rada reaktora, i teskoca u realizovanju plana rada u 1980. godini, ako i podatke o finansiranju projekta 'pogon, odrzavanje i eksploatacija reaktora RA'.

  20. Conservation education in Madagascar: three case studies in the biologically diverse island-continent. (United States)

    Dolins, Francine L; Jolly, Alison; Rasamimanana, Hantanirina; Ratsimbazafy, Jonah; Feistner, Anna T C; Ravoavy, Florent


    Few Malagasy children and adults are aware of the rare and unique fauna and flora indigenous to their island-continent, including flagship lemur species. Even the Malagasy ancestral proverbs never mentioned lemurs, but these same proverbs talked about the now extinct hippopotamus. Madagascar's geography, history, and economic constraints contribute to severe biodiversity loss. Deforestation on Madagascar is reported to be over 100,000 ha/year, with only 10-15% of the island retaining natural forest [Green & Sussman, 1990]. Educating children, teacher-training, and community projects about environmental and conservation efforts to protect the remaining natural habitats of endangered lemur species provide a basis for long-term changes in attitudes and practices. Case studies of three conservation education projects located in different geographical regions of Madagascar, Centre ValBio, Madagacar Wildlife Conservation Alaotra Comic Book Project, and The Ako Book Project, are presented together with their ongoing stages of development, assessment, and outcomes. We argue that while nongovernmental organizational efforts are and will be very important, the Ministry of Education urgently needs to incorporate biodiversity education in the curriculum at all levels, from primary school to university.

However, the factors that influence regional variations in pNTM disease prevalence remain unknown. This study was undertaken to examine whether environmental or occupational factors or host traits could influence regional variations in pNTM disease prevalence. We collected laboratory data on pulmonary tuberculosis (pTB) and pNTM from two hospitals in the West Harima area of Japan and five hospitals in Kyoto City, Japan from 2012 to 2013. We estimated microbiological pNTM disease prevalence by multiplying all pTB cases in each area with the ratio of pNTM cases and pTB cases at the survey hospitals in each area. We administered a standardized questionnaire to 52 patients and 120 patients with pulmonary MAC (pMAC) disease at Ako City Hospital and Kyoto University Hospital, respectively. The estimated prevalence of microbiological pNTM disease in the West Harima area (85.4/100,000 population-years) was significantly higher than that observed in Kyoto City (23.6/100,000 population-years; pdisease prevalence.

    We employed an in vivo Caenorhabditis elegans assay system to perform SOLiD sequencing analysis to identify the possible microRNA (miRNA) targets of multi-walled carbon nanotubes (MWCNTs). Bioinformatics analysis on targeted genes for the identified dysregulated miRNAs in MWCNT exposed nematodes demonstrates their involvement in many aspects of biological processes. We used loss-of-function mutants for the identified dysregulated miRNAs to perform toxicity assessment by evaluating functions of primary and secondary targeted organs, and found the miRNA mutants with susceptible or resistant property towards MWCNT toxicity. Both the physiological state of the intestine and defecation behavior were involved in the control of the susceptible or resistant property occurrence for specific miRNA mutants towards MWCNT toxicity. This work provides the molecular basis at the miRNA level for future chemical design to reduce the nanotoxicity of MWCNTs and further elucidation of the related toxicological mechanism.We employed an in vivo Caenorhabditis elegans assay system to perform SOLiD sequencing analysis to identify the possible microRNA (miRNA) targets of multi-walled carbon nanotubes (MWCNTs).

    Full Text Available BACKGROUND: microRNAs (miRNAs are implicated in regulation of many cellular processes. miRNAs are processed to their mature functional form in a step-wise manner by multiple proteins and cofactors in the nucleus and cytoplasm. Many miRNAs are conserved across vertebrates. Mature miRNAs have recently been characterized in Atlantic halibut (Hippoglossus hippoglossus L.. The aim of this study was to identify and characterize precursor miRNA (pre-miRNAs and miRNA targets in this non-model flatfish. Discovery of miRNA precursor forms and targets in non-model organisms is difficult because of limited source information available. Therefore, we have developed a methodology to overcome this limitation. METHODS: Genomic DNA and small transcriptome of Atlantic halibut were sequenced using Roche 454 pyrosequencing and SOLiD next generation sequencing (NGS, respectively. Identified pre- miRNAs were further validated with reverse-transcription PCR. miRNA targets were identified using miRanda and RNAhybrid target prediction tools using sequences from public databases. Some of miRNA targets were also identified using RACE-PCR. miRNA binding sites were validated with luciferase assay using the RTS34st cell line. RESULTS: We obtained more than 1.3 M and 92 M sequence reads from 454 genomic DNA sequencing and SOLiD small RNA sequencing, respectively. We identified 34 known and 9 novel pre-miRNAs. We predicted a number of miRNA target genes involved in various biological pathways. miR-24 binding to kisspeptin 1 receptor-2 (kiss1-r2 was confirmed using luciferase assay. CONCLUSION: This study demonstrates that identification of conserved and novel pre-miRNAs in a non-model vertebrate lacking substantial genomic resources can be performed by combining different next generation sequencing technologies. Our results indicate a wide conservation of miRNA precursors and involvement of miRNA in multiple regulatory pathways, and provide resources for further research on mi

  6. Vinorelbine induced perforation of a metastatic gastric lesion. (United States)

    Mullally, W J; O'Súilleabháin, C B; Brady, C; O'Reilly, S


    Breast carcinoma metastasis to the gastrointestinal tract is rare and more frequently associated with lobular than ductal carcinoma (Borst and Ingold, Surg 114(4):637-641 [1]). The purpose of this article is to present a case based review of a unique gastrointestinal metastasis and literature review. A 46 year old lady with metastatic invasive ductal breast cancer was admitted to A&E with sudden onset of epigastric and left shoulder pain. She completed the first cycle of capecitabine/vinorelbine 1 week previously. Clinical examination revealed a tender epigastrium with rigidity in the upper abdomen. Free air under the diaphragm and a positive Rigler's sign was radiologically identified. A laparoscopy demonstrated a fibrinous exudate in the left upper quadrant consistent with a walled off lesser curvature gastric perforation. A subsequent oesophagogastroduodenoscopy (OGD) demonstrated a healed gastric ulcer of benign appearance; however the pathology confirmed metastatic breast carcinoma. Literature review confirmed no previously reported cases of vinorelbine induced gastric perforation. Four cases of metastatic breast cancer with gastric metastasis presenting with perforation were identified; three of these cases (Fra et al., Presse Med 25(26):1215 (1996) [2], Solis-Caxaj et al., Gastroenterol Clin Biol 28(1):91-92 (2004) [3], Ghosn et al., Bull Cancer 78(11):1071-1073 (1991) [4]), were in the French medical literature, including one male patient (Fra et al., Presse Med 25(26):1215 (1996) [2]) and at least one ductal breast carcinoma (Solis-Caxaj et al., Gastroenterol Clin Biol 28(1):91-92 (2004) [3]). The fourth case (van Geel et al., Ned Tijdschr Geneeskd 144(37):1761-1763 (2000) [5]), was in the Dutch medical literature and a lobular breast carcinoma. This case represents a rare complication of breast cancer chemotherapy, the subsequent significant benefit the patient received from treatment is consistent with the chemosensitivity to therapy that also resulted

    Full Text Available POSTPOSITIONAL LOCATIVES IN LITHUANIANSummaryThe paper argues that postpositional locatives in Lithuanian (inessive, illative, adessive, allative are not formations of the same epoch, but rather they were formed at different times; the pro­cess of their formation must have been long and continued right up to the appearance of the first Lithuanian printed book when the case-forms fell into a decline. First came singular forms, next — plural forms. More complicated and protracted was the development of inessive and adessive case-forms.Ā- and ē-stem sg. iness. and ill. forms (e. g. šakojè, žẽmėje, šakõn, žẽmėn are considered to be the oldest. The other sg. ill. and particularly sg. iness. forms are products of later development, as they are, as a rule, constructed in the above-mentioned pattern. The paper gives a detailed analysis of the case-forms and on the basis of the analysis it argues that the singular of all postpositional locatives had already been formed and become stable by the beginning of the period of writing -nothing of the kind can be said of the plural. Only illative and allative possessed then stable plural forms.The development of pl. iness. and adess. forms was hindered by the residual ancient Indo-European locative in -su. The centre of the author's attention, however, is the interrelationship of the case-forms and particularly the origin and development of pl. iness. and adess. case-forms.On the basis of a detailed analysis of the old writings, the author argues that the pl. iness. šakosa derives not from šakose, as is generally assumed, but it presents by itself a transformed version of the older form šakosu. The form šakose is to be derived not from the pl. acc. * šakā́s + *éп, but it should be treated as a transform of šakosu от šakosa in -e from the sg. inessive, cf. šakojè. Pl. adess. šakosumpi is not a transform of šakosempi, as is generally assumed, but the older variant of the

    This study evaluated usage of the Army Knowledge Online (AKO) Telemedicine Consultation Program for neurology and traumatic brain injury (TBI) cases in remote overseas areas with limited access to subspecialists. We performed a descriptive analysis of quantity of consults, response times, sites where consults originated, military branches that benefitted, anatomic locations of problems, and diagnoses. This was a retrospective analysis that searched electronic databases for neurology consults from October 2006 to December 2010 and TBI consults from March 2008 to December 2010. A total of 508 consults were received for neurology, and 131 consults involved TBI. For the most part, quantity of consults increased over the years. Meanwhile, response times decreased, with a mean response time of 8 hours, 14 minutes for neurology consults and 2 hours, 44 minutes for TBI consults. Most neurology consults originated in Iraq (67.59%) followed by Afghanistan (16.84%), whereas TBI consults mainly originated from Afghanistan (40.87%) followed by Iraq (33.91%). The most common consultant diagnoses were headaches, including migraines (52.1%), for neurology cases and mild TBI/concussion (52.3%) for TBI cases. In the majority of cases, consultants recommended in-theater management. After receipt of consultant's recommendation, 84 known neurology evacuations were facilitated, and 3 known neurology evacuations were prevented. E-mail-based neurology and TBI subspecialty teleconsultation is a viable method for overseas providers in remote locations to receive expert recommendations for a range of neurologic conditions. These recommendations can facilitate medically necessary patient evacuations or prevent evacuations for which on-site care is preferable.

    In this study, a three-step extraction method (separately use acetone, hexane, and ethanol as extraction solvent in each step) was conducted to selectively extract three types of krill oils with different compositions. The lipid yields were 5.08% in step 1, 4.80% in step 2, and 9.11% in step 3, with a total of 18.99%. The krill oil extracted with acetone in step 1 (A-KO) contained the lowest contents of phospholipids (PL) (2.32%) and n-3 polyunsaturated fatty acids (PUFA) (16.63%), but the highest levels of minor components (505.00 mg/kg of astaxanthin, 29.39 mg/100 g of tocopherols, 34.32 mg/100 g of vitamin A and 27.95 mg/g of cholesterol). By contrast, despite having traces of minor components, the krill oil extracted using ethanol in step 3 (E-KO) was the most abundant in PL (59.52%) and n-3 PUFA (41.74%). The krill oil extracted using hexane in step 2 (H-KO) expressed medium contents of all the testing indices. The oils showed significant differences in the antioxidant capacity (E-KO > H-KO > A-KO) which exhibited positive correlation with the PL content. These results could be used for further development of a wide range of krill oil products with tailor-made functions. Copyright © 2017 Elsevier Ltd. All rights reserved.

  15. Fructose-induced increases in expression of intestinal fructolytic and gluconeogenic genes are regulated by GLUT5 and KHK (United States)

    Patel, Chirag; Douard, Veronique; Yu, Shiyan; Tharabenjasin, Phuntila; Gao, Nan


    Marked increases in fructose consumption have been tightly linked to metabolic diseases. One-third of ingested fructose is metabolized in the small intestine, but the underlying mechanisms regulating expression of fructose-metabolizing enzymes are not known. We used genetic mouse models to test the hypothesis that fructose absorption via glucose transporter protein, member 5 (GLUT5), metabolism via ketohexokinase (KHK), as well as GLUT5 trafficking to the apical membrane via the Ras-related protein in brain 11a (Rab11a)-dependent endosomes are required for the regulation of intestinal fructolytic and gluconeogenic enzymes. Fructose feeding increased the intestinal mRNA and protein expression of these enzymes in the small intestine of adult wild-type (WT) mice compared with those gavage fed with lysine or glucose. Fructose did not increase expression of these enzymes in the GLUT5 knockout (KO) mice. Blocking intracellular fructose metabolism by KHK ablation also prevented fructose-induced upregulation. Glycolytic hexokinase I expression was similar between WT and GLUT5- or KHK-KO mice and did not vary with feeding solution. Gavage feeding with the fructose-specific metabolite glyceraldehyde did not increase enzyme expression, suggesting that signaling occurs before the hydrolysis of fructose to three-carbon compounds. Impeding GLUT5 trafficking to the apical membrane using intestinal epithelial cell-specific Rab11a-KO mice impaired fructose-induced upregulation. KHK expression was uniformly distributed along the villus but was localized mainly in the basal region of the cytosol of enterocytes. The feedforward upregulation of fructolytic and gluconeogenic enzymes specifically requires GLUT5 and KHK and may proactively enhance the intestine's ability to process anticipated increases in dietary fructose concentrations.

  16. Transport, metabolism, and endosomal trafficking-dependent regulation of intestinal fructose absorption (United States)

    Patel, Chirag; Douard, Veronique; Yu, Shiyan; Gao, Nan; Ferraris, Ronaldo P.


    Dietary fructose that is linked to metabolic abnormalities can up-regulate its own absorption, but the underlying regulatory mechanisms are not known. We hypothesized that glucose transporter (GLUT) protein, member 5 (GLUT5) is the primary fructose transporter and that fructose absorption via GLUT5, metabolism via ketohexokinase (KHK), as well as GLUT5 trafficking to the apical membrane via the Ras-related protein-in-brain 11 (Rab11)a-dependent endosomes are each required for regulation. Introducing fructose but not lysine and glucose solutions into the lumen increased by 2- to 10-fold the heterogeneous nuclear RNA, mRNA, protein, and activity levels of GLUT5 in adult wild-type mice consuming chow. Levels of GLUT5 were >100-fold that of candidate apical fructose transporters GLUTs 7, 8, and 12 whose expression, and that of GLUT 2 and the sodium-dependent glucose transporter protein 1 (SGLT1), was not regulated by luminal fructose. GLUT5-knockout (KO) mice exhibited no facilitative fructose transport and no compensatory increases in activity and expression of SGLT1 and other GLUTs. Fructose could not up-regulate GLUT5 in GLUT5-KO, KHK-KO, and intestinal epithelial cell-specific Rab11a-KO mice. The fructose-specific metabolite glyceraldehyde did not increase GLUT5 expression. GLUT5 is the primary transporter responsible for facilitative absorption of fructose, and its regulation specifically requires fructose uptake and metabolism and normal GLUT5 trafficking to the apical membrane.—Patel, C., Douard, V., Yu, S., Gao, N., Ferraris, R.

U radu se apostrofira nepoznavanje ili nedovoljno poznavanje zakonodavca prilikom donošenja propisa koji tangiraju problematiku morske obale, čime unose nedosljednosti i zabunu u primjenu referentnih propisa te u konačnici i pravnu nesigurnost u ovoj oblasti u Republici Hrvatskoj. Naznačuju se i mogući pravci rješavanja uočenih problema kroz prijedloge primjene integralnog upravljanja morskom obalom uz anticipiranje nekih novih rješenja i ukazivanje na obvezu pridržavanja europskog zakonodavstva i posebno precedentnih odluka nadležnih europskih sudova. Zaključno se ukazuje da naši teoretičari i praktičari koji se bave reguliranjem materije koja se referira na morsku obalu, nažalost, ne uvažavaju propise i sudsku praksu Europske unije koji su postali sastavni dio našeg pozitivnog zakonodavstva. Stoga se Republika Hrvatska izlaže opasnosti da ju Europska unija kao i pojedini zainteresirani subjekti prozivaju za nepoštivanje prava i sankcioniraju u smislu europske sudske prakse, a da te opasnosti nismo uopće svjesni. Isto tako, gledanje na morsku obalu kao prirodni resurs koji u Hrvatskoj ni izdaleka nije iskorišten na adekvatan način, je nužnost koja se nameće Hrvatskoj kao jednoj prezaduženoj zemlji ako želi gospodarski napredak kako države tako i njenih stanovnika.

It is stated that a complete and efficient control of tritium activity, from radiation protection point of view can be achieved only by simultaneous triple measurements: direct measurement of tritium in the air by stationary or movable instruments; air sampling and measurement of activity by laboratory instrumentation; and measurement of tritium in the bio-material of the personnel who have inhaled air contaminated with tritium. Laboratory equipment was adapted for tritium detection in air samples. A method for measuring the specific tritium activity was developed and implemented. The tritium level and distribution in the air were measured during exchange of the fuel channel in the RA reactor. The obtained results indicate that tritium could be dangerous for the staff involved.

    Full Text Available Autism spectrum disorder (ASD has a strong genetic basis, although the genetics of autism is complex and it is unclear. Genetic testing such as microarray or sequencing was widely used to identify autism markers, but they are unsuccessful in several cases. The objective of this study is to identify causative variants of autism in two Thai families by using whole-exome sequencing technique. Whole-exome sequencing was performed with autism-affected children from two unrelated families. Each sample was sequenced on SOLiD 5500xl Genetic Analyzer system followed by combined bioinformatics pipeline including annotation and filtering process to identify candidate variants. Candidate variants were validated, and the segregation study with other family members was performed using Sanger sequencing. This study identified a possible causative variant for ASD, c.2951G>A, in the FGD6 gene. We demonstrated the potential for ASD genetic variants associated with ASD using whole-exome sequencing and a bioinformatics filtering procedure. These techniques could be useful in identifying possible causative ASD variants, especially in cases in which variants cannot be identified by other techniques.

  4. Impact of atmospheric components on solar clear-sky models at different elevation: Case study Canary Islands

    Antonanzas-Torres, F.; Antonanzas, J.; Urraca, R.; Alia-Martinez, M.; Martinez-de-Pison, F.J.


    Highlights: • Assessment on the performance of solar clear-sky models at different altitude. • SOLIS and REST2 clear-sky models were superior with fine atmospheric inputs. • ESRA proved more robust with low spatial resolution atmospheric inputs. • Over-estimation occurred at the lower site when using inputs from the upper site. - Abstract: The estimation of clear-sky solar irradiance via clear-sky models depends on reliable values of aerosol optical depth, water vapor and ozone content. These atmospheric variables are rarely on-site measured and are generally provided as gridded estimates in very low spatial resolution (1°). The high spatial variability of atmospheric variables within the grid resolution (pixel) leads to important errors in those areas with great atmospheric variability, such as in mountainous regions. In this paper, the performance of three clear-sky solar irradiance models was evaluated in a site with especially great elevation range, the Izana station from the Baseline Surface Radiation Network (Tenerife, Canary Islands) located at a high elevation (2373 m) and just 14 km from the ocean. Aerosols data were obtained from measurements from the Aerosol Robotic Network (AERONET) at the same site. The evaluation was also compared with global horizontal irradiance estimations with clear-sky models in the Guimar station, located at a lower elevation (156 m) and only 11.5 km away from Izana. Results showed a strong influence of elevation on solar radiation estimation under clear-sky conditions.

    Performance of photovoltaic (PV) module is greatly dependent on the solar irradiance, operating temperature, and shading. Solar irradiance can have a significant impact on power output of PV module and energy yield. In this paper, a maximum PV power which can be obtain in Ramadi city (100km west of Baghdad) is practically analyzed. The analysis is based on real irradiance values obtained as the first time by using Soly2 sun tracker device. Proper and adequate information on solar radiation and its components at a given location is very essential in the design of solar energy systems. The solar irradiance data in Ramadi city were analyzed based on the first three months of 2013. The solar irradiance data are measured on earth's surface in the campus area of Anbar University. Actual average data readings were taken from the data logger of sun tracker system, which sets to save the average readings for each two minutes and based on reading in each one second. The data are analyzed from January to the end of March-2013. Maximum daily readings and monthly average readings of solar irradiance have been analyzed to optimize the output of photovoltaic solar modules. The results show that the system sizing of PV can be reduced by 12.5% if a tracking system is used instead of fixed orientation of PV modules.

Carbon nanotubes (CNTs and silk fibroin (SF were used to modify the surface of the nHA/PA66 scaffolds by freeze-drying and cross-linking. Dexamethasone was absorbed to the CNTs to promote the osteogenic differentiation of bone mesenchymal stem cells (BMSCs. The cell viability of BMSCs was investigated by changing the concentration of the CNT dispersion, and the most biocompatible scaffold was selected. In addition, the morphology and mechanical property of the scaffolds were investigated. The results showed that the nHA/PA66 scaffolds modified with CNTs and SF met the requirements of bone tissue engineering scaffolds. The dexamethasone-loaded CNT/SF-nHA/PA66 composite scaffold promoted the osteogenic differentiation of BMSCs, and the drug-loaded scaffolds are expected to function as effective bone tissue engineering scaffolds.

    The force-free parameter α, also known as helicity parameter or twist parameter, bears the same sign as the magnetic helicity under some restrictive conditions. The single global value of α for a whole active region gives the degree of twist per unit axial length. We investigate the effect of polarimetric noise on the calculation of global α value and magnetic energy of an analytical bipole. The analytical bipole has been generated using the force-free field approximation with a known value of constant α and magnetic energy. The magnetic parameters obtained from the analytical bipole are used to generate Stokes profiles from the Unno-Rachkovsky solutions for polarized radiative transfer equations. Then we add random noise of the order of 10 -3 of the continuum intensity (I c ) in these profiles to simulate the real profiles obtained by modern spectropolarimeters such as Hinode (SOT/SP), SVM (USO), ASP, DLSP, POLIS, and SOLIS etc. These noisy profiles are then inverted using a Milne-Eddington inversion code to retrieve the magnetic parameters. Hundred realizations of this process of adding random noise and polarimetric inversion is repeated to study the distribution of error in global α and magnetic energy values. The results show that (1) the sign of α is not influenced by polarimetric noise and very accurate values of global twist can be calculated, and (2) accurate estimation of magnetic energy with uncertainty as low as 0.5% is possible under the force-free condition.

    Full Text Available The shotgun sequencing data presented in this report are related to the research article named “Gut microbiome shotgun sequencing in assessment of microbial community changes associated with H. pylori eradication therapy” (Khusnutdinova et al., 2016 [1]. Typically, the H. pylori eradication protocol includes a prolonged two-week use of the broad-spectrum antibiotics. The presented data on the whole-genome sequencing of the total DNA from stool samples of patients before the start of the eradication, immediately after eradication and several weeks after the end of treatment could help to profile the gut microbiota both taxonomically and functionally. The presented data together with those described in Glushchenko et al. (2017 [2] allow researchers to characterize the metagenomic profiles in which the use of antibiotics could result in dramatic changes in the intestinal microbiota composition. We perform 15 gut metagenomes from 5 patients with H. pylori infection, obtained through the shotgun sequencing on the SOLiD 5500 W platform. Raw reads are deposited in the ENA under project ID PRJEB21338.

  9. The first Chameleon transcriptome: comparative genomic analysis of the OXPHOS system reveals loss of COX8 in Iguanian lizards. (United States)

    Bar-Yaacov, Dan; Bouskila, Amos; Mishmar, Dan


    Recently, we found dramatic mitochondrial DNA divergence of Israeli Chamaeleo chamaeleon populations into two geographically distinct groups. We aimed to examine whether the same pattern of divergence could be found in nuclear genes. However, no genomic resource is available for any chameleon species. Here we present the first chameleon transcriptome, obtained using deep sequencing (SOLiD). Our analysis identified 164,000 sequence contigs of which 19,000 yielded unique BlastX hits. To test the efficacy of our sequencing effort, we examined whether the chameleon and other available reptilian transcriptomes harbored complete sets of genes comprising known biochemical pathways, focusing on the nDNA-encoded oxidative phosphorylation (OXPHOS) genes as a model. As a reference for the screen, we used the human 86 (including isoforms) known structural nDNA-encoded OXPHOS subunits. Analysis of 34 publicly available vertebrate transcriptomes revealed orthologs for most human OXPHOS genes. However, OXPHOS subunit COX8 (Cytochrome C oxidase subunit 8), including all its known isoforms, was consistently absent in transcriptomes of iguanian lizards, implying loss of this subunit during the radiation of this suborder. The lack of COX8 in the suborder Iguania is intriguing, since it is important for cellular respiration and ATP production. Our sequencing effort added a new resource for comparative genomic studies, and shed new light on the evolutionary dynamics of the OXPHOS system.

  10. Enhanced mineralization of diuron using a cyclodextrin-based bioremediation technology. (United States)

    The phenylurea herbicide diuron [N-(3,4-dichlorophenyl)-N,N-dimethylurea] is widely used in a broad range of herbicide formulations and, consequently, it is frequently detected as a major soil and water contaminant in areas where there is extensive use. Diuron has the unfortunate combination of being strongly adsorbed by soil organic matter particles and, hence, slowly degraded in the environment due to its reduced bioavailability. N-Phenylurea herbicides seem to be biodegraded in soil, but it must be kept in mind that this biotic or abiotic degradation could lead to accumulation of very toxic derived compounds, such as 3,4-dichloroaniline. Research was conducted to find procedures that might result in an increase in the bioavailability of diuron in contaminated soils, through solubility enhancement. For this purpose a double system composed of hydroxypropyl-β-cyclodextrin (HPBCD), which is capable of forming inclusion complexes in solution, and a two-member bacterial consortium formed by the diuron-degrading Arthrobacter sulfonivorans (Arthrobacter sp. N2) and the linuron-degrading Variovorax soli (Variovorax sp. SRS16) was used. This consortium can achieve a complete biodegradation of diuron to CO2 with regard to that observed in the absence of the CD solution, where only a 45% biodegradation was observed. The cyclodextrin-based bioremediation technology here described shows for the first time an almost complete mineralization of diuron in a soil system, in contrast to previous incomplete mineralization based on single or consortium bacterial degradation.

    Thirty-six rabbits were included in a study investigating into the effects of split-dose 300 KV X-irradiation on the cornea, ciliary body, nictitating membrane and lacrimal gland. In each animal, soly the right the eye was irradiated using total doses of 21 Gy, 30 Gy, 36 Gy and 45 Gy that were administered according to a fixed schedule in fractions of 3 Gy five times per week. After latency periods of six weeks, three months and six months the animals receiving 21 Gy, 30 Gy and 36 Gy showed no changes of the bulbi, eye lids and lacrimal glands that could be ascertained by histopathological evaluation. In the animals exposed to the 45 Gy dose, changes of the cornea and conjunctiva caused by radiation injuries to the lacrimal glands and conjunctival goblet cells started to appear after a minimum period of 3 months. This dose level was also the threshold for the occurrence of corneal damage or even ulceration as a result of secondary reduction or qualitative change of lacrimal secretions. (ECB) [de

  14. The reversal of the Sun’s magnetic field in cycle 24

    Directory of Open Access Journals (Sweden)

    Mordvinov A.V.


    Full Text Available Analysis of synoptic data from the Vector Spectromagnetograph (VSM of the Synoptic Optical Long-term Investigations of the Sun (SOLIS and the NASA/NSO Spectromagnetograph (SPM at the NSO/Kitt Peak Vacuum Telescope facility shows that the reversals of solar polar magnetic fields exhibit elements of a stochastic process, which may include the development of specific patterns of emerging magnetic flux, and the asymmetry in activity between Northern and Southern hemispheres. The presence of such irregularities makes the modeling and prediction of polar field reversals extremely hard if possible. In a classical model of solar activity cycle, the unipolar magnetic regions (UMRs of predominantly following polarity fields are transported polewards due to meridional flows and diffusion. The UMRs gradually cancel out the polar magnetic field of the previous cycle, and rebuild the polar field of opposite polarity setting the stage for the next cycle. We show, however, that this deterministic picture can be easily altered by the developing of a strong center of activity, or by the emergence of an extremely large active region, or by a ‘strategically placed’ coronal hole. We demonstrate that the activity occurring during the current cycle 24 may be the result of this randomness in the evolution of the solar surface magnetic field.

  15. Gender differences in cognitive development. (United States)

    Ardila, Alfredo; Rosselli, Monica; Matute, Esmeralda; Inozemtseva, Olga


    The potential effect of gender on intellectual abilities remains controversial. The purpose of this research was to analyze gender differences in cognitive test performance among children from continuous age groups. For this purpose, the normative data from 7 domains of the newly developed neuropsychological test battery, the Evaluación Neuropsicológica Infantil [Child Neuropsychological Assessment] (Matute, Rosselli, Ardila, & Ostrosky-Solis, 2007), were analyzed. The sample included 788 monolingual children (350 boys, 438 girls) ages 5 to 16 years from Mexico and Colombia. Gender differences were observed in oral language (language expression and language comprehension), spatial abilities (recognition of pictures seen from different angles), and visual (Object Integration Test) and tactile perceptual tasks, with boys outperforming girls in most cases, except for the tactile tasks. Gender accounted for only a very small percentage of the variance (1%-3%). Gender x Age interactions were observed for the tactile tasks only. It was concluded that gender differences during cognitive development are minimal, appear in only a small number of tests, and account for only a low percentage of the score variance.

  16. Late Tharsis tectonic activity and implications for Early Mars (United States)

    Bouley, S.; Baratoux, D.; Paulien, N.; Missenard, Y.; Saint-Bezar, B.


    Constraining the timing of Tharsis volcanism is critical to understanding the planet's evolution including its climate, surface environment and mantle dynamics. The tectonic history of the Tharsis bulge was previously documented from the distribution and ages of related tectonic features [1]. Here we revisit the ages of 7493 Tharsis-related tectonic features based on their relationship with stratigraphic units defined in the new geological map [2]. Conversely to previous tectonic mapping [1], which suggested that Tharsis growth was nearly achieved during the Noachian, we find a protracted growth of Tharsis during the Hesperian. Faulting at Tempe Terra, Claritas and Coracis Fossae and Thaumasia Planum confirms that tectonic deformation started during the Noachian. Accumulated tectonic deformation was maximum in the Early Hesperian for compressional strain (Solis, Lunae and Ascuris Planum) and extended over time from Noachian to Amazonian for extensional strain (Noctis Labyrinthus and Fossae, Sinai Planum and Tractus, Ulysses and Fortuna fossae, Alba Patera). This new scenario is consistent with a protracted growth of Tharsis dome during the Hesperian and with the timing a large Tharsis-driven true polar wander post-dating the incision of Late Noachian/Hesperian valley networks[3].

  17. A New Approach for Flexible Molecular Docking Based on Swarm Intelligence

    Directory of Open Access Journals (Sweden)

    Yi Fu


    Full Text Available Molecular docking methods play an important role in the field of computer-aided drug design. In the work, on the basis of the molecular docking program AutoDock, we present QLDock as a tool for flexible molecular docking. For the energy evaluation, the algorithm uses the binding free energy function that is provided by the AutoDock 4.2 tool. The new search algorithm combines the features of a quantum-behaved particle swarm optimization (QPSO algorithm and local search method of Solis and Wets for solving the highly flexible protein-ligand docking problem. We compute the interaction of 23 protein-ligand complexes and compare the results with those of the QDock and AutoDock programs. The experimental results show that our approach leads to substantially lower docking energy and higher docking precision in comparison to Lamarckian genetic algorithm and QPSO algorithm alone. QPSO-ls algorithm was able to identify the correct binding mode of 74% of the complexes. In comparison, the accuracy of QPSO and LGA is 52% and 61%, respectively. This difference in performance rises with increasing complexity of the ligand. Thus, the novel algorithm QPSO-ls may be used to dock ligand with many rotatable bonds with high accuracy.

    Here we use the PFSS model and photospheric data from Wilcox Solar Observatory, SOHO /MDI, SDO/HMI, and SOLIS to compare the coronal field with heliospheric magnetic field measured at 1 au, compiled in the NASA/NSSDC OMNI 2 data set. We calculate their mutual polarity match and the power of the radial decay, p , of the radial field using different source surface distances and different number of harmonic multipoles. We find the average polarity match of 82% for the declining phase, 78%–79% for maxima, 76%–78% for the ascending phase, and 74%–76% for minima. On an average, the source surface of 3.25 R{sub S} gives the best polarity match. We also find strong evidence for solar cycle variation of the optimal source surface distance, with highest values (3.3 R{sub S}) during solar minima and lowest values (2.6 R{sub S}–2.7 R{sub S}) during the other three solar cycle phases. Raising the number of harmonic terms beyond 2 rarely improves the polarity match, showing that the structure of the HMF at 1 au is most of the time rather simple. All four data sets yield fairly similar polarity matches. Thus, polarity comparison is not affected by photospheric field scaling, unlike comparisons of the field intensity.

  19. Variety of RNAs in Peripheral Blood Cells, Plasma, and Plasma Fractions (United States)

    Kuligina, Elena V.; Bariakin, Dmitry N.; Kozlov, Vadim V.; Richter, Vladimir A.; Semenov, Dmitry V.


    Human peripheral blood contains RNA in cells and in extracellular membrane vesicles, microvesicles and exosomes, as well as in cell-free ribonucleoproteins. Circulating mRNAs and noncoding RNAs, being internalized, possess the ability to modulate vital processes in recipient cells. In this study, with SOLiD sequencing technology, we performed identification, classification, and quantification of RNAs from blood fractions: cells, plasma, plasma vesicles pelleted at 16,000g and 160,000g, and vesicle-depleted plasma supernatant of healthy donors and non-small cell lung cancer (NSCLC) patients. It was determined that 16,000g blood plasma vesicles were enriched with cell-free mitochondria and with a set of mitochondrial RNAs. The variable RNA set of blood plasma 160,000g pellets reflected the prominent contribution of U1, U5, and U6 small nuclear RNAs' fragments and at the same time was characterized by a remarkable depletion of small nucleolar RNAs. Besides microRNAs, the variety of fragments of mRNAs and snoRNAs dominated in the set of circulating RNAs differentially expressed in blood fractions of NSCLC patients. Taken together, our data emphasize that not only extracellular microRNAs but also circulating fragments of messenger and small nuclear/nucleolar RNAs represent prominent classes of circulating regulatory ncRNAs as well as promising circulating biomarkers for the development of disease diagnostic approaches.

  20. High-throughput sequencing of black pepper root transcriptome (United States)


    Background Black pepper (Piper nigrum L.) is one of the most popular spices in the world. It is used in cooking and the preservation of food and even has medicinal properties. Losses in production from disease are a major limitation in the culture of this crop. The major diseases are root rot and foot rot, which are results of root infection by Fusarium solani and Phytophtora capsici, respectively. Understanding the molecular interaction between the pathogens and the host’s root region is important for obtaining resistant cultivars by biotechnological breeding. Genetic and molecular data for this species, though, are limited. In this paper, RNA-Seq technology has been employed, for the first time, to describe the root transcriptome of black pepper. Results The root transcriptome of black pepper was sequenced by the NGS SOLiD platform and assembled using the multiple-k method. Blast2Go and orthoMCL methods were used to annotate 10338 unigenes. The 4472 predicted proteins showed about 52% homology with the Arabidopsis proteome. Two root proteomes identified 615 proteins, which seem to define the plant’s root pattern. Simple-sequence repeats were identified that may be useful in studies of genetic diversity and may have applications in biotechnology and ecology.

  1. Flavobacterium lindanitolerans sp. nov., isolated from hexachlorocyclohexane-contaminated soil. (United States)

    Jit, Simran; Dadhwal, Mandeep; Prakash, Om; Lal, Rup


    A Gram-negative, non-spore-forming, cream-yellow-pigmented bacterial strain, IP-10(T), was isolated from soil samples from a waste site highly contaminated with hexachlorocyclohexane in Ummari village, India. The organism showed the highest 16S rRNA gene sequence similarity of 92.7 % with Flavobacterium soli KCTC 12542(T) and levels of 87-92 % with the type strains of other recognized species of the genus Flavobacterium. The DNA G+C content of strain IP-10(T) was 31 mol%. The predominant fatty acids were iso-C(15 : 0) (22.1 %), iso-C(17 : 0) 3-OH (18.5 %) and summed feature 3 (comprising C(16 : 1)omega7c and/or iso-C(15 : 0) 2-OH; 13.2 %). Strain IP-10(T) could be differentiated from recognized species of the genus Flavobacterium based on a number of phenotypic features. Strain IP-10(T) is therefore considered to represent a novel species of the genus Flavobacterium, for which the name Flavobacterium lindanitolerans sp. nov. is proposed. The type strain is IP-10(T) (=MTCC 8597(T)=CCM 7424(T)).

    Populations of Noccaea caerulescens show tremendous differences in their capacity to hyperaccumulate and hypertolerate metals. To explore the differences that could contribute to these traits, we undertook SOLiD high-throughput sequencing of the root transcriptomes of three phenotypically well-characterized N. caerulescens accessions, i.e., Ganges, La Calamine, and Monte Prinzera. Genes with possible contribution to zinc, cadmium, and nickel hyperaccumulation and hypertolerance were predicted. The most significant differences between the accessions were related to metal ion (di-, trivalent inorganic cation) transmembrane transporter activity, iron and calcium ion binding, (inorganic) anion transmembrane transporter activity, and antioxidant activity. Analysis of correlation between the expression profile of each gene and the metal-related characteristics of the accessions disclosed both previously characterized (HMA4, HMA3) and new candidate genes (e.g., for nickel IRT1, ZIP10, and PDF2.3) as possible contributors to the hyperaccumulation/tolerance phenotype. A number of unknown Noccaea-specific transcripts also showed correlation with Zn(2+), Cd(2+), or Ni(2+) hyperaccumulation/tolerance. This study shows that N. caerulescens populations have evolved great diversity in the expression of metal-related genes, facilitating adaptation to various metalliferous soils. The information will be helpful in the development of improved plants for metal phytoremediation.

    High-throughput DNA sequencing has enabled systems biology to begin to address areas in health, agricultural and basic biological research. Concomitant with the opportunities is an absolute necessity to manage significant volumes of high-dimensional and inter-related data and analysis. Alpheus is an analysis pipeline, database and visualization software for use with massively parallel DNA sequencing technologies that feature multi-gigabase throughput characterized by relatively short reads, such as Illumina-Solexa (sequencing-by-synthesis), Roche-454 (pyrosequencing) and Applied Biosystem's SOLiD (sequencing-by-ligation). Alpheus enables alignment to reference sequence(s), detection of variants and enumeration of sequence abundance, including expression levels in transcriptome sequence. Alpheus is able to detect several types of variants, including non-synonymous and synonymous single nucleotide polymorphisms (SNPs), insertions/deletions (indels), premature stop codons, and splice isoforms. Variant detection is aided by the ability to filter variant calls based on consistency, expected allele frequency, sequence quality, coverage, and variant type in order to minimize false positives while maximizing the identification of true positives. Alpheus also enables comparisons of genes with variants between cases and controls or bulk segregant pools. Sequence-based differential expression comparisons can be developed, with data export to SAS JMP Genomics for statistical analysis.

    Directory of Open Access Journals (Sweden)

    Full Text Available La storia dei doni simbolici inviati da Dario a Alessandro Magno (Romanzo di Alessandro 1.36-38 è derivata da una raccolta ellenistica di lettere fittizie che raccontavano la spedizione del conquistatore Macedone. Un modello diretto di quella narrazione fu la leggenda sui regali enigmatici mandati dagli Sciti a Dario I, che è narrata da Erodoto (4.131-132 e altre fonti ed era ben nota nell’epoca ellenistica. Oltre a questo, la storia di Alessandro e Dario è anche influenzata da tradizioni orali di folclore e divertimento, ugualmente riconducibili all’età ellenistica. Il re Persiano e quello Macedone competono nell’offerta di spiegazioni contrastanti degli oggetti simbolici; le loro spiegazioni sono collocate in una sorta di scala ascendente dal più debole al più forte. Secondo l’interpretazione di Alessandro, gli oggetti rappresentano le nozioni di potere e di conquista, superando in tal modo l’allegoria più debole di puerilità e sottomissione proposta da Dario. Questo schema narrativo ricorda giochi di enigmi con analoga struttura a gradi, che vengono attestati da Difilo e Clearco di Soli per simposi di prima età ellenistica. In tali gare scherzose, due o più giocatori tentavano di superarsi l’un l’altro, trovando ogni volta una soluzione più forte per lo stesso indovinello.

    A gamma radiation-resistant and pink-to-red pigmented bacterial strain, designated ID1504 T , was isolated from a car air-conditioning system sampled in Korea. The cells were observed to be Gram-stain negative, aerobic, motile with peritrichous flagella and short rod-shaped. Phylogenetically, the strain groups with the members of the genus Deinococcus and exhibits high 16S rRNA gene sequence similarities with Deinococcus arenae SA1 T (94.0%), Deinococcus actinosclerus BM2 T (93.9%) and Deinococcus soli N5 T (93.5%). The predominant fatty acids were identified as C 17:0 , C 16:0 , summed feature 3 (C 16:1 ω7c and/or C 16:1 ω6c) and iso-C 17:0 . The major respiratory quinone was identified as MK-8. The polar lipids were found to be comprised of unidentified phospholipids, unidentified glycolipids, an unidentified aminophospholipid and an unidentified lipid. The DNA G+C content of the strain was determined to be 68.3 mol%. On the basis of the phenotypic, genotypic and chemotaxonomic characteristics, strain ID1504 T should be classified in a novel species in the genus Deinococcus, for which the name Deinococcus multiflagellatus sp. nov. (= KACC 19287 T  = NBRC 112888 T ) is proposed.

  6. The dazed and confused identity of Agassiz’s land tortoise, Gopherus agassizii (Testudines: Testudinidae with the description of a new species and its consequences for conservation

    Directory of Open Access Journals (Sweden)

    Robert Murphy


    Full Text Available We investigate a cornucopia of problems associated with the identity of the desert tortoise, Gopherus agassizii Cooper. The date of publication is found to be 1861, rather than 1863. Only one of the three original cotypes exists, and it is designated as the lectotype of the species. Another cotype is found to have been destroyed in the 1906 San Francisco earthquake and subsequent fire. The third is lost. The lectotype is genetically confirmed to be from California, and not Arizona, USA as sometimes reported. Maternally, the holotype of G. lepidocephalus Ottley et Velázques Solis, 1989 from the Cape Region of Baja California Sur, Mexico is also from the Mojavian population of the desert tortoise, and not from Tiburon Island, Sonora, Mexico as previously proposed. A suite of characters serve to diagnose tortoises west and north of the Colorado River, the Mojavian population, from those east and south of the river in Arizona, USA and Sonora and Sinaloa, Mexico, the Sonoran population. Species recognition is warranted and because G. lepidocephalus is from the Mojavian population no names are available for the Sonoran species. Thus, a new species, Gopherus morafkai sp. n., is named and this action reduces the distribution of G. agassizii to only 30% of its former range. This reduction has important implications for the conservation and protection of G. agassizii, which may deserve a higher level of protection.

    We present the analysis of an unusual failed eruption captured in high cadence and in many wavelengths during the observing campaign in support of the Very high Angular resolution Ultraviolet Telescope ( VAULT2.0 ) sounding rocket launch. The refurbished VAULT2.0 is a Ly α ( λ 1216 Å) spectroheliograph launched on 2014 September 30. The campaign targeted active region NOAA AR 12172 and was closely coordinated with the Hinode and IRIS missions and several ground-based observatories (NSO/IBIS, SOLIS, and BBSO). A filament eruption accompanied by a low-level flaring event (at the GOES C-class level) occurred around the VAULT2.0 launch. No coronal mass ejection was observed. The eruption and its source region, however, were recorded by the campaign instruments in many atmospheric heights ranging from the photosphere to the corona in high cadence and spatial resolution. This is a rare occasion that enabled us to perform a comprehensive investigation on a failed eruption. We find that a rising Magnetic Flux Rope (MFR)-like structure was destroyed during its interaction with the ambient magnetic field, creating downflows of cool plasma and diffuse hot coronal structures reminiscent of “cusps.” We employ magnetofrictional simulations to show that the magnetic topology of the ambient field is responsible for the destruction of the MFR. Our unique observations suggest that the magnetic topology of the corona is a key ingredient for a successful eruption.

    Previous solar axion searches have been carried out in Brookhaven (1990) and in Tokyo (2000- ), tracking the Sun with a dipole magnet. QCD inspired axions should be produced after the Big Bang, being thus candidates for the dark matter. The Sun is a very useful source of weakly interacting particles for fundamental research. Axions can be produced also in the Sun's core through the scattering of thermal photons in the Coulomb field of electric charges (Primakoff effect). In a transverse magnetic field the Primakoff effect can work in reverse, coherently converting the solar axions or other axion-like particles (ALPS) back into X-ray photons in the keV range. The conversion efficiency increases with $(B⋅L)^2$. In the CAST experiment an LHC prototype dipole magnet (B = 9 T and L = 10 m) with straight beam pipes provides a conversion efficiency exceeding that of the two earlier solar axion telescopes by almost a factor of 100. This magnet is mounted on a moving platform and coupled to both gas filled and soli...

  10. Pantani di Marco Martinelli: una narrazione polifonica

    Directory of Open Access Journals (Sweden)

    Franco Nasi


    Full Text Available In questo articolo si analizza il testo drammaturgico Pantani di Marco Martinelli, una veglia epica teatrale di uno dei più noti eroi dello sport italiano degli ultimi anni. Il dramma rilegge anche la storia di Pantani e ricostruisce gli strani avvenimenti che portarono alla sospensione, alla estromissione del ciclista dal Giro d’Italia nel 1999, e in seguito alla sua profonda crisi psicologica e tragica morte in solitudine in un hotel, a soli 34 anni. Oltre alle modalità proprie della veglia rituale, il dramma utilizza anche i metodi del processo giudiziario, e offre testimonianze dettagliate che conducono a una riflessione critica sulla società italiana negli anni del potere politico di Berlusconi e della sua filosofia del consumismo. I tre diversi generi della retorica classica (epidittico, giudiziario e deliberativo si mescolano in questa complessa tessitura teatrale. Coniugando informazioni (processo e rito (veglia, Martinelli riesce a fondere la tragedia greca (forma mimetica e corale e il moderno teatro di narrazione (forma diegetica monologante. Combinando assieme scene intensamente drammatiche, ricordi di imprese sportive epiche, passaggi giocosi e parodici, e giustapponendo vari stili e registri (giornalistico, lirico, parodico, elegiaco, Martinelli crea momenti di forte “straniamento” e sorpresa, e rende particolarmente efficace il rito funebre, la ricostruzione storica della tragica vicenda di Pantani e la critica all’ideologia che ha dominato l’Italia negli anni di Berlusconi.

  11. High-throughput sequencing of black pepper root transcriptome

    Directory of Open Access Journals (Sweden)

    Gordo Sheila MC


    Full Text Available Abstract Background Black pepper (Piper nigrum L. is one of the most popular spices in the world. It is used in cooking and the preservation of food and even has medicinal properties. Losses in production from disease are a major limitation in the culture of this crop. The major diseases are root rot and foot rot, which are results of root infection by Fusarium solani and Phytophtora capsici, respectively. Understanding the molecular interaction between the pathogens and the host’s root region is important for obtaining resistant cultivars by biotechnological breeding. Genetic and molecular data for this species, though, are limited. In this paper, RNA-Seq technology has been employed, for the first time, to describe the root transcriptome of black pepper. Results The root transcriptome of black pepper was sequenced by the NGS SOLiD platform and assembled using the multiple-k method. Blast2Go and orthoMCL methods were used to annotate 10338 unigenes. The 4472 predicted proteins showed about 52% homology with the Arabidopsis proteome. Two root proteomes identified 615 proteins, which seem to define the plant’s root pattern. Simple-sequence repeats were identified that may be useful in studies of genetic diversity and may have applications in biotechnology and ecology. Conclusions This dataset of 10338 unigenes is crucially important for the biotechnological breeding of black pepper and the ecogenomics of the Magnoliids, a major group of basal angiosperms.

  12. A study of catasterisms in the 'phaenomena' of Aratus (United States)

    Rousseau, A.; Dimitrakoudis, S.

    We provide a fresh analysis of the constellations in Aratos Phenomena by using the astronomical program Cybersky (by Stephen Schimpf) to check each reference of constellations within the poem for validity in 2800 BCE and 300 BCE (the later accounting for the broader period of time covering Eudoxus of Cnidus and Aratus of Soli). In each case, the latitude of observation was chose to be 36 North in agreement with the area of the sky that is not covered in the descriptions of Aratus (and contains the unseen constellations for a particular latitude). Each constellation was traced back to its Greek mythological origin through tha various writers of antiquity. Our results are collected in a table of the constellations mentioned by Aratus in his epic poem, with respect to the ancient authors who have mentioned each constellation shaping its myth, the locations on the earth each constellation is associated with and the most likely date of observation according to Aratus description and taking into account precession and the proper motion of stars.

    Challis Danny


    Full Text Available Abstract Background Whole exome capture sequencing allows researchers to cost-effectively sequence the coding regions of the genome. Although the exome capture sequencing methods have become routine and well established, there is currently a lack of tools specialized for variant calling in this type of data. Results Using statistical models trained on validated whole-exome capture sequencing data, the Atlas2 Suite is an integrative variant analysis pipeline optimized for variant discovery on all three of the widely used next generation sequencing platforms (SOLiD, Illumina, and Roche 454. The suite employs logistic regression models in conjunction with user-adjustable cutoffs to accurately separate true SNPs and INDELs from sequencing and mapping errors with high sensitivity (96.7%. Conclusion We have implemented the Atlas2 Suite and applied it to 92 whole exome samples from the 1000 Genomes Project. The Atlas2 Suite is available for download at In addition to a command line version, the suite has been integrated into the Genboree Workbench, allowing biomedical scientists with minimal informatics expertise to remotely call, view, and further analyze variants through a simple web interface. The existing genomic databases displayed via the Genboree browser also streamline the process from variant discovery to functional genomics analysis, resulting in an off-the-shelf toolkit for the broader community.

  14. Two new species of philometrid nematodes (Nematoda: Philometridae) in Epinephelus coioides (Hamilton, 1822) from the South Bali Sea, Indonesia. (United States)

    Dewi, Kartika; Palm, Harry W


    Based on light and scanning electron microscopy, two new species of philometrid nematodes, Spirophilometra endangae sp. nov. and Philometra epinepheli sp. nov. (Nematoda: Dracunculoidea: Philometridae) are described from Epinephelus coioides (Hamilton, 1822) (Perciformes: Serranidae) from the South Bali Sea, Indonesia. Spirophilometra endangae sp. nov. was isolated from the fins of E. coioides. The new species can be distinguished from the most closely related S. eichleri Parukhin, 1971 by a larger total body length and the site of infection in the host. The new species differs from S. centropomi (Caballero, 1974) also in the larger body size of the gravid females and the site of infection in the host. S. en-dangae sp. nov. differs from S. pacifica (Moravec, Santana-Pineros, Gonzales-Solis & Torres-Huerta, 2007) in the struc-ture and arrangement of the spines on the middle part of the body, the infection site of the worm, the type host and the zoogeographical host distribution. Philometra epinepheli sp. nov. differs from all other Philometra spp. congeners so far recorded from Ephinepelus groupers in the total body length and the site of infection. This is the first opercula-infecting species of Philometra described from the fish family Serranidae.

  15. Enhanced crude oil biodegradation in soil via biostimulation. (United States)

    Al-Saleh, Esmaeil; Hassan, Ali


    Research on feasible methods for the enhancement of bioremediation in soil contaminated by crude oil is vital in oil-exporting countries such as Kuwait, where crude oil is a major pollutant and the environment is hostile to biodegradation. This study investigated the possibility of enhancing crude oil bioremediation by supplementing soil with cost-effective organic materials derived from two widespread locally grown trees, Conocarpus and Tamarix. Amendments in soils increased the counts of soil microbiota by up to 98% and enhanced their activity by up to 95.5%. The increase in the biodegradation of crude oil (75%) and high levels of alkB expression substantiated the efficiency of the proposed amendment technology for the bioremediation of hydrocarbon-contaminated sites. The identification of crude-oil-degrading bacteria revealed the dominance of the genus Microbacterium (39.6%), Sphingopyxis soli (19.3%), and Bordetella petrii (19.6%) in unamended, Conocarpus-amended, and Tamarix-amended contaminated soils, respectively. Although soil amendments favored the growth of Gram-negative bacteria and reduced bacterial diversity, the structures of bacterial communities were not significantly altered.

  16. LFQC: a lossless compression algorithm for FASTQ files (United States)

    Nicolae, Marius; Pathak, Sudipta; Rajasekaran, Sanguthevar


    Motivation: Next Generation Sequencing (NGS) technologies have revolutionized genomic research by reducing the cost of whole genome sequencing. One of the biggest challenges posed by modern sequencing technology is economic storage of NGS data. Storing raw data is infeasible because of its enormous size and high redundancy. In this article, we address the problem of storage and transmission of large FASTQ files using innovative compression techniques. Results: We introduce a new lossless non-reference based FASTQ compression algorithm named Lossless FASTQ Compressor. We have compared our algorithm with other state of the art big data compression algorithms namely gzip, bzip2, fastqz (Bonfield and Mahoney, 2013), fqzcomp (Bonfield and Mahoney, 2013), Quip (Jones et al., 2012), DSRC2 (Roguski and Deorowicz, 2014). This comparison reveals that our algorithm achieves better compression ratios on LS454 and SOLiD datasets. Availability and implementation: The implementations are freely available for non-commercial purposes. They can be downloaded from Contact: PMID:26093148

  18. Toxicity evaluation of textile effluents and role of native soil bacterium in biodegradation of a textile dye. (United States)

    Khan, Sana; Malik, Abdul


    Water pollution caused by the discharge of hazardous textile effluents is a serious environmental problem worldwide. In order to assess the pollution level of the textile effluents, various physico-chemical parameters were analyzed in the textile wastewater and agricultural soil irrigated with the wastewater (contaminated soil) using atomic absorption spectrophotometer and gas chromatography-mass spectrometry (GC-MS) analysis that demonstrated the presence of several toxic heavy metals (Ni, Cu, Cr, Pb, Cd, and Zn) and a large number of organic compounds. Further, in order to get a comprehensive idea about the toxicity exerted by the textile effluent, mung bean seed germination test was performed that indicated the reduction in percent seed germination and radicle-plumule growth. The culturable microbial populations were also enumerated and found to be significantly lower in the wastewater and contaminated soil than the ground water irrigated soil, thus indicating the biotic homogenization of indigenous microflora. Therefore, the study was aimed to develop a cost effective and ecofriendly method of textile waste treatment using native soil bacterium, identified as Arthrobacter soli BS5 by 16S rDNA sequencing that showed remarkable ability to degrade a textile dye reactive black 5 with maximum degradation of 98% at 37 °C and pH in the range of 5-9 after 120 h of incubation.

  19. Isolation and characterization of oxalotrophic bacteria from tropical soils. (United States)

    Bravo, Daniel; Braissant, Olivier; Cailleau, Guillaume; Verrecchia, Eric; Junier, Pilar


    The oxalate-carbonate pathway (OCP) is a biogeochemical set of reactions that involves the conversion of atmospheric CO2 fixed by plants into biomass and, after the biological recycling of calcium oxalate by fungi and bacteria, into calcium carbonate in terrestrial environments. Oxalotrophic bacteria are a key element of this process because of their ability to oxidize calcium oxalate. However, the diversity and alternative carbon sources of oxalotrophs participating to this pathway are unknown. Therefore, the aim of this study was to characterize oxalotrophic bacteria in tropical OCP systems from Bolivia, India, and Cameroon. Ninety-five oxalotrophic strains were isolated and identified by sequencing of the 16S rRNA gene. Four genera corresponded to newly reported oxalotrophs (Afipia, Polaromonas, Humihabitans, and Psychrobacillus). Ten strains were selected to perform a more detailed characterization. Kinetic curves and microcalorimetry analyses showed that Variovorax soli C18 has the highest oxalate consumption rate with 0.240 µM h(-1). Moreover, Streptomyces achromogenes A9 displays the highest metabolic plasticity. This study highlights the phylogenetic and physiological diversity of oxalotrophic bacteria in tropical soils under the influence of the oxalate-carbonate pathway.

  20. Applications of isotope techniques for the assessment of soil phosphorus status and evaluation of rock phosphates as phosphorus sources for plants in subtropical China

    International Nuclear Information System (INIS)

    Xiong, L.M.; Zhou, Z.G.; Feng, G.L.; Lu, R.K.; Fardeau, J.C.


    In an attempt to assess current soil phosphorus status and evaluate the effectiveness of local rock phosphates in subtropical China, nearly 40 representative soil samples from this region were collected and characterized by using 32 P isotope and chemical extraction techniques. Pot experiments, incubation studies and field trials were conducted to investigate the interaction of rock phosphates and water-soluble phosphates as well as the effects of rock phosphate on soil chemical properties in selected soils. Results indicated that these soils were generally low in available phosphorus and high in P-fixing capacity. The soil characteristics dictated that the employed isotope kinetic model was less successful in predicting plant P uptake than the chemical procedures tested. A new chemical extraction method consisting of sodium bicarbonate and ammonium fluoride was proposed to evaluate available P in these Solis. Data on available P generated with the proposed method gave the best prediction of plant uptake amongst all methods compared. In a pot experiment, the combined application of soluble P fertilizer with local rock phosphate significantly enhanced plant growth and increased P uptake. This positive interaction was attributed to the improved soil chemical properties due to the application of low-grade rock phosphates, as demonstrated in incubation studies. These results suggest that rock phosphate-based fertilizers should be good alternative fertilizers for plants in similar acidic soils in southern China. (author)

  1. microRNA expression profiling in fetal single ventricle malformation identified by deep sequencing. (United States)

    Yu, Zhang-Bin; Han, Shu-Ping; Bai, Yun-Fei; Zhu, Chun; Pan, Ya; Guo, Xi-Rong


    microRNAs (miRNAs) have emerged as key regulators in many biological processes, particularly cardiac growth and development, although the specific miRNA expression profile associated with this process remains to be elucidated. This study aimed to characterize the cellular microRNA profile involved in the development of congenital heart malformation, through the investigation of single ventricle (SV) defects. Comprehensive miRNA profiling in human fetal SV cardiac tissue was performed by deep sequencing. Differential expression of 48 miRNAs was revealed by sequencing by oligonucleotide ligation and detection (SOLiD) analysis. Of these, 38 were down-regulated and 10 were up-regulated in differentiated SV cardiac tissue, compared to control cardiac tissue. This was confirmed by real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) analysis. Predicted target genes of the 48 differentially expressed miRNAs were analyzed by gene ontology and categorized according to cellular process, regulation of biological process and metabolic process. Pathway-Express analysis identified the WNT and mTOR signaling pathways as the most significant processes putatively affected by the differential expression of these miRNAs. The candidate genes involved in cardiac development were identified as potential targets for these differentially expressed microRNAs and the collaborative network of microRNAs and cardiac development related-mRNAs was constructed. These data provide the basis for future investigation of the mechanism of the occurrence and development of fetal SV malformations.

    Erik Knutsen

    Full Text Available MicroRNA profiling represents an important first-step in deducting individual RNA-based regulatory function in a cell, tissue, or at a specific developmental stage. Currently there are several different platforms to choose from in order to make the initial miRNA profiles. In this study we investigate recently developed digital microRNA high-throughput technologies. Four different platforms were compared including next generation SOLiD ligation sequencing and Illumina HiSeq sequencing, hybridization-based NanoString nCounter, and miRCURY locked nucleic acid RT-qPCR. For all four technologies, full microRNA profiles were generated from human cell lines that represent noninvasive and invasive tumorigenic breast cancer. This study reports the correlation between platforms, as well as a more extensive analysis of the accuracy and sensitivity of data generated when using different platforms and important consideration when verifying results by the use of additional technologies. We found all the platforms to be highly capable for microRNA analysis. Furthermore, the two NGS platforms and RT-qPCR all have equally high sensitivity, and the fold change accuracy is independent of individual miRNA concentration for NGS and RT-qPCR. Based on these findings we propose new guidelines and considerations when performing microRNA profiling.

    We present the analysis of an unusual failed eruption captured in high cadence and in many wavelengths during the observing campaign in support of the Very high Angular resolution Ultraviolet Telescope ( VAULT2.0 ) sounding rocket launch. The refurbished VAULT2.0 is a Ly α ( λ 1216 Å) spectroheliograph launched on 2014 September 30. The campaign targeted active region NOAA AR 12172 and was closely coordinated with the Hinode and IRIS missions and several ground-based observatories (NSO/IBIS, SOLIS, and BBSO). A filament eruption accompanied by a low-level flaring event (at the GOES C-class level) occurred around the VAULT2.0 launch. No coronal mass ejection was observed. The eruption and its source region, however, were recorded by the campaign instruments in many atmospheric heights ranging from the photosphere to the corona in high cadence and spatial resolution. This is a rare occasion that enabled us to perform a comprehensive investigation on a failed eruption. We find that a rising Magnetic Flux Rope (MFR)-like structure was destroyed during its interaction with the ambient magnetic field, creating downflows of cool plasma and diffuse hot coronal structures reminiscent of “cusps.” We employ magnetofrictional simulations to show that the magnetic topology of the ambient field is responsible for the destruction of the MFR. Our unique observations suggest that the magnetic topology of the corona is a key ingredient for a successful eruption.

  5. Digital PCR provides sensitive and absolute calibration for high throughput sequencing

    Directory of Open Access Journals (Sweden)

    Fan H Christina


    Full Text Available Abstract Background Next-generation DNA sequencing on the 454, Solexa, and SOLiD platforms requires absolute calibration of the number of molecules to be sequenced. This requirement has two unfavorable consequences. First, large amounts of sample-typically micrograms-are needed for library preparation, thereby limiting the scope of samples which can be sequenced. For many applications, including metagenomics and the sequencing of ancient, forensic, and clinical samples, the quantity of input DNA can be critically limiting. Second, each library requires a titration sequencing run, thereby increasing the cost and lowering the throughput of sequencing. Results We demonstrate the use of digital PCR to accurately quantify 454 and Solexa sequencing libraries, enabling the preparation of sequencing libraries from nanogram quantities of input material while eliminating costly and time-consuming titration runs of the sequencer. We successfully sequenced low-nanogram scale bacterial and mammalian DNA samples on the 454 FLX and Solexa DNA sequencing platforms. This study is the first to definitively demonstrate the successful sequencing of picogram quantities of input DNA on the 454 platform, reducing the sample requirement more than 1000-fold without pre-amplification and the associated bias and reduction in library depth. Conclusion The digital PCR assay allows absolute quantification of sequencing libraries, eliminates uncertainties associated with the construction and application of standard curves to PCR-based quantification, and with a coefficient of variation close to 10%, is sufficiently precise to enable direct sequencing without titration runs.

Tako i u tom starom gradiću oživje sve kada sat sa zvonika crkve Presvete Djevice Marije s dvanaest muklih, teških udaraca otkuca ponoć. Kamenje na pločniku počelo je razgovarati s vlatima trave koja je među njim rasla i pitalo je koliko još misli ostati. Zabati i erkeri kuća u uskim zamršenim uličicama kimali su jedni drugima, a ulične svjetiljke žalile su se na vjetar; prehladile su se jer on tako bezobzirno mijenja smjer.Također oživje sve i u starom vinskom podrumu staroga gradića. Mnogobrojne bačve koje stajahu jedne pokraj drugih, velike i male, zijevnuše i protegnuše se i ispružiše se, a kad bi jedna drugu pritom gurnula, rekla bi: „Oh, tisuću puta oprostite!“ Jer bačve su vrlo pristojne i znaju se lijepo ponašati. Tada bi sve uspravno stale na svoje debele nožice – naime, bačve imaju nožice, ako glupi ljudi ne znaju ni to – i sve bi se klanjale jedne drugima i kimale si i pozdravljale se na sve stane.

    Full Text Available Procjene za prosječan porast morske razine na globalnoj razini do kraja 21. stoljeća najčešće variraju od 0,18 m do ≥ 1 m u odnosu na današnju razinu. Ako se razmatraju procjene koje obuhvaćaju i otapanje grenlandskog i antarktičkog ledenog pokrova, tada se može očekivati porast morske razine od 5 i više m. Sukladno s globalnim promjenama, razina Jadranskog mora također je u porastu. Radi analize potencijalne ugroženosti hrvatske obale od porasta morske razine, izrađena su tri modela porasta razine Jadranskog mora (od 1 m, 3 m i 6 m. Na temelju modela analizira se utjecaj porasta morske razine na različite socioekonomske segmente obalnog prostora. Cilj je istraživanja definirati najugroženije dijelove hrvatske obale. Kako bi se mogli diferencirati najugroženiji dijelovi, izrađen je Indeks ugroženosti obalnih općina ( . U izradi Indeksa koristili su se analizom utjecaja dobiveni kvantitativni podaci o prostornom obuhvatu poplavnih zona te ugroženosti stanovništva i prometne infrastrukture obalne zone. Navedenim su varijablama s pomoću Analitičkog hijerarhijskog procesa (AHP pridruženi različiti težinski koeficijenti, ovisno o važnosti varijable. Pri analizi svih triju modela uočeno je kako se Zadar i njegova okolica ističu kao najugroženije područje hrvatske obale. Zbog toga je na primjeru Zadra izvršena znatno detaljnija analiza mikrolokacijskog utjecaja porasta morske razine. Podaci dobiveni analizom različitih modela pokazuju kako je gotovo cijela hrvatska obala ugrožena, ali i da postoji velik nerazmjer u razini ugroženosti pojedinih dijelova hrvatske obale. Važnost je ovog istraživanja u tome što ono predstavlja temelj za pravovremenu adaptaciju na negativne utjecaje budućeg porasta razine Jadranskog mora.

  16. Harnessing cross-species alignment to discover SNPs and generate a draft genome sequence of a bighorn sheep (Ovis canadensis). (United States)

    Miller, Joshua M; Moore, Stephen S; Stothard, Paul; Liao, Xiaoping; Coltman, David W


    Whole genome sequences (WGS) have proliferated as sequencing technology continues to improve and costs decline. While many WGS of model or domestic organisms have been produced, a growing number of non-model species are also being sequenced. In the absence of a reference, construction of a genome sequence necessitates de novo assembly which may be beyond the ability of many labs due to the large volumes of raw sequence data and extensive bioinformatics required. In contrast, the presence of a reference WGS allows for alignment which is more tractable than assembly. Recent work has highlighted that the reference need not come from the same species, potentially enabling a wide array of species WGS to be constructed using cross-species alignment. Here we report on the creation a draft WGS from a single bighorn sheep (Ovis canadensis) using alignment to the closely related domestic sheep (Ovis aries). Two sequencing libraries on SOLiD platforms yielded over 865 million reads, and combined alignment to the domestic sheep reference resulted in a nearly complete sequence (95% coverage of the reference) at an average of 12x read depth (104 SD). From this we discovered over 15 million variants and annotated them relative to the domestic sheep reference. We then conducted an enrichment analysis of those SNPs showing fixed differences between the reference and sequenced individual and found significant differences in a number of gene ontology (GO) terms, including those associated with reproduction, muscle properties, and bone deposition. Our results demonstrate that cross-species alignment enables the creation of novel WGS for non-model organisms. The bighorn sheep WGS will provide a resource for future resequencing studies or comparative genomics.

  17. Development of Prediction Model and Experimental Validation in Predicting the Curcumin Content of Turmeric (Curcuma longa L.). (United States)

    Akbar, Abdul; Kuanar, Ananya; Joshi, Raj K; Sandeep, I S; Mohanty, Sujata; Naik, Pradeep K; Mishra, Antaryami; Nayak, Sanghamitra


    The drug yielding potential of turmeric ( Curcuma longa L.) is largely due to the presence of phyto-constituent 'curcumin.' Curcumin has been found to possess a myriad of therapeutic activities ranging from anti-inflammatory to neuroprotective. Lack of requisite high curcumin containing genotypes and variation in the curcumin content of turmeric at different agro climatic regions are the major stumbling blocks in commercial production of turmeric. Curcumin content of turmeric is greatly influenced by environmental factors. Hence, a prediction model based on artificial neural network (ANN) was developed to map genome environment interaction basing on curcumin content, soli and climatic factors from different agroclimatic regions for prediction of maximum curcumin content at various sites to facilitate the selection of suitable region for commercial cultivation of turmeric. The ANN model was developed and tested using a data set of 119 generated by collecting samples from 8 different agroclimatic regions of Odisha. The curcumin content from these samples was measured that varied from 7.2% to 0.4%. The ANN model was trained with 11 parameters of soil and climatic factors as input and curcumin content as output. The results showed that feed-forward ANN model with 8 nodes (MLFN-8) was the most suitable one with R 2 value of 0.91. Sensitivity analysis revealed that minimum relative humidity, altitude, soil nitrogen content and soil pH had greater effect on curcumin content. This ANN model has shown proven efficiency for predicting and optimizing the curcumin content at a specific site.

    We study long-lived activity complexes and their current helicity at the solar surface and their kinetic helicity below the surface. The current helicity has been determined from synoptic vector magnetograms from the NSO/SOLIS facility, and the kinetic helicity of subsurface flows has been determined with ring-diagram analysis applied to full-disk Dopplergrams from NSO/GONG and SDO/HMI. Current and kinetic helicity of activity complexes follow the hemispheric helicity rule with mainly positive values (78%; 78%, respectively, with a 95% confidence level of 31%) in the southern hemisphere and negative ones (80%; 93%, respectively, with a 95% confidence level of 22% and 14%, respectively) in the northern hemisphere. The locations with the dominant sign of kinetic helicity derived from Global Oscillation Network Group (GONG) and SDO/HMI data are more organized than those of the secondary sign even if they are not part of an activity complex, while locations with the secondary sign are more fragmented. This is the case for both hemispheres even for the northern one where it is not as obvious visually due to the large amount of magnetic activity present as compared to the southern hemisphere. The current helicity shows a similar behavior. The dominant sign of current helicity is the same as that of kinetic helicity for the majority of the activity complexes (83% with a 95% confidence level of 15%). During the 24 Carrington rotations analyzed here, there is at least one longitude in each hemisphere where activity complexes occur repeatedly throughout the epoch. These ''active'' longitudes are identifiable as locations of strong current and kinetic helicity of the same sign

    A Gram-positive, strictly aerobic, rod-shaped, non-motile bacterial strain, designated MJ28T, was isolated from a sludge sample from the Daejeon sewage disposal plant in South Korea. A polyphasic approach was applied to study the taxonomic position of strain MJ28T. Strain MJ28T showed highest 16S rRNA gene sequence similarity to Pseudoclavibacter soli KP02T (95.2 %). Levels of 16S rRNA gene sequence similarity to the type strains of other Pseudoclavibacter species were less than 94.0 %. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MJ28T belonged to the clade formed by members of the genus Pseudoclavibacter in the family Microbacteriaceae. The G+C content of the genomic DNA of strain MJ28T was 65.8 mol%. The chemotaxonomic characteristics of strain MJ28T showed features typical of the genus Pseudoclavibacter, with MK-9 as the predominant respiratory quinone, 2,4-diaminobutryic acid as the diamino acid in the peptidoglycan, and anteiso-C17:0 (44.6 %), anteiso-C15:0 (35.7 %) and C16:0 (9.5 %) as the major fatty acids. On the basis of phylogenetic inference, fatty acid profile and other phenotypic properties, strain MJ28T is considered to represent a novel species of the genus Pseudoclavibacter, for which the name Pseudoclavibacter caeni sp. nov. is proposed. The type strain is MJ28T (=KCTC 19773T=JCM 16921T).

    Full Text Available We report here identification and validation of the first papillomavirus encoded microRNAs expressed in human cervical lesions and cell lines. We established small RNA libraries from ten human papillomavirus associated cervical lesions including cancer and two human papillomavirus harboring cell lines. These libraries were sequenced using SOLiD 4 technology. We used the sequencing data to predict putative viral microRNAs and discovered nine putative papillomavirus encoded microRNAs. Validation was performed for five candidates, four of which were successfully validated by qPCR from cervical tissue samples and cell lines: two were encoded by HPV 16, one by HPV 38 and one by HPV 68. The expression of HPV 16 microRNAs was further confirmed by in situ hybridization, and colocalization with p16INK4A was established. Prediction of cellular target genes of HPV 16 encoded microRNAs suggests that they may play a role in cell cycle, immune functions, cell adhesion and migration, development, and cancer. Two putative viral target sites for the two validated HPV 16 miRNAs were mapped to the E5 gene, one in the E1 gene, two in the L1 gene and one in the LCR region. This is the first report to show that papillomaviruses encode their own microRNA species. Importantly, microRNAs were found in libraries established from human cervical disease and carcinoma cell lines, and their expression was confirmed in additional tissue samples. To our knowledge, this is also the first paper to use in situ hybridization to show the expression of a viral microRNA in human tissue.

    The bacterial SOS response is a well-characterized regulatory network encoded by most prokaryotic bacterial species and is involved in DNA repair. In addition to nucleic acid repair, the SOS response is involved in pathogenicity, stress-induced mutagenesis, and the emergence and dissemination of antibiotic resistance. Using high-throughput sequencing technology (SOLiD RNA-Seq), we analyzed the Burkholderia thailandensis global SOS response to the fluoroquinolone antibiotic, ciprofloxacin (CIP), and the DNA-damaging chemical, mitomycin C (MMC). We demonstrate that a B. thailandensis recA mutant (RU0643) is ∼4-fold more sensitive to CIP in contrast to the parental strain B. thailandensis DW503. Our RNA-Seq results show that CIP and MMC treatment (P SOS response were induced and include lexA, uvrA, dnaE, dinB, recX, and recA. At the genome-wide level, we found an overall decrease in gene expression, especially for genes involved in amino acid and carbohydrate transport and metabolism, following both CIP and MMC exposure. Interestingly, we observed the upregulation of several genes involved in bacterial motility and enhanced transcription of a B. thailandensis genomic island encoding a Siphoviridae bacteriophage designated E264. Using B. thailandensis plaque assays and PCR with B. mallei ATCC 23344 as the host, we demonstrate that CIP and MMC exposure in B. thailandensis DW503 induces the transcription and translation of viable bacteriophage in a RecA-dependent manner. This is the first report of the SOS response in Burkholderia spp. to DNA-damaging agents. We have identified both common and unique adaptive responses of B. thailandensis to chemical stress and DNA damage.

  2. Next-generation small RNA sequencing for microRNAs profiling in the honey bee Apis mellifera. (United States)

    MicroRNAs (miRNAs) are key regulators in various physiological and pathological processes via post-transcriptional regulation of gene expression. The honey bee (Apis mellifera) is a key model for highly social species, and its complex social behaviour can be interpreted theoretically as changes in gene regulation, in which miRNAs are thought to be involved. We used the SOLiD sequencing system to identify the repertoire of miRNAs in the honey bee by sequencing a mixed small RNA library from different developmental stages. We obtained a total of 36,796,459 raw sequences; of which 5,491,100 short sequences were fragments of mRNA and other noncoding RNAs (ncRNA), and 1,759,346 reads mapped to the known miRNAs. We predicted 267 novel honey bee miRNAs representing 380,182 short reads, including eight miRNAs of other insects in 14,107,583 genome-mapped sequences. We verified 50 of them using stem-loop reverse-transcription PCR (RT-PCR), in which 35 yielded PCR products. Cross-species analyses showed 81 novel miRNAs with homologues in other insects, suggesting that they were authentic miRNAs and have similar functions. The results of this study provide a basis for studies of the miRNA-modulating networks in development and some intriguing phenomena such as caste differentiation in A. mellifera. © 2010 The Authors.

  3. First Use of Synoptic Vector Magnetograms for Global Nonlinear, Force-Free Coronal Magnetic Field Models (United States)

    Tadesse, T.; Wiegelmann, T.; Gosain, S.; MacNeice, P.; Pevtsov, A. A.


    Context. The magnetic field permeating the solar atmosphere is generally thought to provide the energy for much of the activity seen in the solar corona, such as flares, coronal mass ejections (CMEs), etc. To overcome the unavailability of coronal magnetic field measurements, photospheric magnetic field vector data can be used to reconstruct the coronal field. Currently, there are several modelling techniques being used to calculate three-dimensional field lines into the solar atmosphere. Aims. For the first time, synoptic maps of a photospheric-vector magnetic field synthesized from the vector spectromagnetograph (VSM) on Synoptic Optical Long-term Investigations of the Sun (SOLIS) are used to model the coronal magnetic field and estimate free magnetic energy in the global scale. The free energy (i.e., the energy in excess of the potential field energy) is one of the main indicators used in space weather forecasts to predict the eruptivity of active regions. Methods. We solve the nonlinear force-free field equations using an optimization principle in spherical geometry. The resulting threedimensional magnetic fields are used to estimate the magnetic free energy content E(sub free) = E(sub nlfff) - E(sub pot), which is the difference of the magnetic energies between the nonpotential field and the potential field in the global solar corona. For comparison, we overlay the extrapolated magnetic field lines with the extreme ultraviolet (EUV) observations by the atmospheric imaging assembly (AIA) on board the Solar Dynamics Observatory (SDO). Results. For a single Carrington rotation 2121, we find that the global nonlinear force-free field (NLFFF) magnetic energy density is 10.3% higher than the potential one. Most of this free energy is located in active regions.

  4. Role of Host-Driven Mutagenesis in Determining Genome Evolution of Sigma Virus (DMelSV; Rhabdoviridae) in Drosophila melanogaster. (United States)

    Piontkivska, Helen; Matos, Luis F; Paul, Sinu; Scharfenberg, Brian; Farmerie, William G; Miyamoto, Michael M; Wayne, Marta L


    Sigma virus (DMelSV) is ubiquitous in natural populations of Drosophila melanogaster. Host-mediated, selective RNA editing of adenosines to inosines (ADAR) may contribute to control of viral infection by preventing transcripts from being transported into the cytoplasm or being translated accurately; or by increasing the viral genomic mutation rate. Previous PCR-based studies showed that ADAR mutations occur in DMelSV at low frequency. Here we use SOLiD TM deep sequencing of flies from a single host population from Athens, GA, USA to comprehensively evaluate patterns of sequence variation in DMelSV with respect to ADAR. GA dinucleotides, which are weak targets of ADAR, are strongly overrepresented in the positive strand of the virus, consistent with selection to generate ADAR resistance on this complement of the transient, double-stranded RNA intermediate in replication and transcription. Potential ADAR sites in a worldwide sample of viruses are more likely to be "resistant" if the sites do not vary among samples. Either variable sites are less constrained and hence are subject to weaker selection than conserved sites, or the variation is driven by ADAR. We also find evidence of mutations segregating within hosts, hereafter referred to as hypervariable sites. Some of these sites were variable only in one or two flies (i.e., rare); others were shared by four or even all five of the flies (i.e., common). Rare and common hypervariable sites were indistinguishable with respect to susceptibility to ADAR; however, polymorphism in rare sites were more likely to be consistent with the action of ADAR than in common ones, again suggesting that ADAR is deleterious to the virus. Thus, in DMelSV, host mutagenesis is constraining viral evolution both within and between hosts. © The Author 2016.

  6. Comparative Analyses of H3K4 and H3K27 Trimethylations Between the Mouse Cerebrum and Testis

    KAUST Repository

    Cui, Peng


    The global features of H3K4 and H3K27 trimethylations (H3K4me3 and H3K27me3) have been well studied in recent years, but most of these studies were performed in mammalian cell lines. In this work, we generated the genome-wide maps of H3K4me3 and H3K27me3 of mouse cerebrum and testis using ChIP-seq and their high-coverage transcriptomes using ribominus RNA-seq with SOLiD technology. We examined the global patterns of H3K4me3 and H3K27me3 in both tissues and found that modifications are closely-associated with tissue-specific expression, function and development. Moreover, we revealed that H3K4me3 and H3K27me3 rarely occur in silent genes, which contradicts the findings in previous studies. Finally, we observed that bivalent domains, with both H3K4me3 and H3K27me3, existed ubiquitously in both tissues and demonstrated an invariable preference for the regulation of developmentally-related genes. However, the bivalent domains tend towards a “winner-takes-all” approach to regulate the expression of associated genes. We also verified the above results in mouse ES cells. As expected, the results in ES cells are consistent with those in cerebrum and testis. In conclusion, we present two very important findings. One is that H3K4me3 and H3K27me3 rarely occur in silent genes. The other is that bivalent domains may adopt a “winner-takes-all” principle to regulate gene expression.

    Recent observations of the photosphere using high spatial and temporal resolution show small dynamic features at or below the current resolving limits. A new pixel dynamics method has been developed to analyze spectral profiles and quantify changes in line displacement, width, asymmetry, and peakedness of photospheric absorption lines. The algorithm evaluates variations of line profile properties in each pixel and determines the statistics of such fluctuations averaged over all pixels in a given region. The method has been used to derive statistical characteristics of pixel fluctuations in observed quiet-Sun regions, an active region with no eruption, and an active region with an ongoing eruption. Using Stokes I images from the Vector Spectromagnetograph (VSM) of the Synoptic Optical Long-term Investigations of the Sun (SOLIS) telescope on 2012 March 13, variations in line width and peakedness of Fe i 6301.5 Å are shown to have a distinct spatial and temporal relationship with an M7.9 X-ray flare in NOAA 11429. This relationship is observed as stationary and contiguous patches of pixels adjacent to a sunspot exhibiting intense flattening in the line profile and line-center displacement as the X-ray flare approaches peak intensity, which is not present in area scans of the non-eruptive active region. The analysis of pixel dynamics allows one to extract quantitative information on differences in plasma dynamics on sub-pixel scales in these photospheric regions. The analysis can be extended to include the Stokes parameters and study signatures of vector components of magnetic fields and coupled plasma properties.

  8. A Solar Position Sensor Based on Image Vision. (United States)

    Ruelas, Adolfo; Velázquez, Nicolás; Villa-Angulo, Carlos; Acuña, Alexis; Rosales, Pedro; Suastegui, José


    Solar collector technologies operate with better performance when the Sun beam direction is normal to the capturing surface, and for that to happen despite the relative movement of the Sun, solar tracking systems are used, therefore, there are rules and standards that need minimum accuracy for these tracking systems to be used in solar collectors' evaluation. Obtaining accuracy is not an easy job, hence in this document the design, construction and characterization of a sensor based on a visual system that finds the relative azimuth error and height of the solar surface of interest, is presented. With these characteristics, the sensor can be used as a reference in control systems and their evaluation. The proposed sensor is based on a microcontroller with a real-time clock, inertial measurement sensors, geolocation and a vision sensor, that obtains the angle of incidence from the sunrays' direction as well as the tilt and sensor position. The sensor's characterization proved how a measurement of a focus error or a Sun position can be made, with an accuracy of 0.0426° and an uncertainty of 0.986%, which can be modified to reach an accuracy under 0.01°. The validation of this sensor was determined showing the focus error on one of the best commercial solar tracking systems, a Kipp & Zonen SOLYS 2. To conclude, the solar tracking sensor based on a vision system meets the Sun detection requirements and components that meet the accuracy conditions to be used in solar tracking systems and their evaluation or, as a tracking and orientation tool, on photovoltaic installations and solar collectors.

  9. High-throughput sequencing of microRNAs in peripheral blood mononuclear cells: identification of potential weight loss biomarkers.

    Fermín I Milagro

    Full Text Available INTRODUCTION: MicroRNAs (miRNAs are being increasingly studied in relation to energy metabolism and body composition homeostasis. Indeed, the quantitative analysis of miRNAs expression in different adiposity conditions may contribute to understand the intimate mechanisms participating in body weight control and to find new biomarkers with diagnostic or prognostic value in obesity management. OBJECTIVE: The aim of this study was the search for miRNAs in blood cells whose expression could be used as prognostic biomarkers of weight loss. METHODS: Ten Caucasian obese women were selected among the participants in a weight-loss trial that consisted in following an energy-restricted treatment. Weight loss was considered unsuccessful when 5% (responders. At baseline, total miRNA isolated from peripheral blood mononuclear cells (PBMC was sequenced with SOLiD v4. The miRNA sequencing data were validated by RT-PCR. RESULTS: Differential baseline expression of several miRNAs was found between responders and non-responders. Two miRNAs were up-regulated in the non-responder group (mir-935 and mir-4772 and three others were down-regulated (mir-223, mir-224 and mir-376b. Both mir-935 and mir-4772 showed relevant associations with the magnitude of weight loss, although the expression of other transcripts (mir-874, mir-199b, mir-766, mir-589 and mir-148b also correlated with weight loss. CONCLUSIONS: This research addresses the use of high-throughput sequencing technologies in the search for miRNA expression biomarkers in obesity, by determining the miRNA transcriptome of PBMC. Basal expression of different miRNAs, particularly mir-935 and mir-4772, could be prognostic biomarkers and may forecast the response to a hypocaloric diet.

    There is mounting evidence that regulatory variation plays an important role in genetic risk for schizophrenia. Here, we specifically search for regulatory variants at risk by sequencing promoter regions of twenty-three genes implied in schizophrenia by copy number variant or genome-wide association studies. After strict quality control, a total of 55,206bp per sample were analyzed in 526 schizophrenia cases and 516 controls from Galicia, NW Spain, using the Applied Biosystems SOLiD System. Variants were filtered based on frequency from public databases, chromatin states from the RoadMap Epigenomics Consortium at tissues relevant for schizophrenia, such as fetal brain, mid-frontal lobe, and angular gyrus, and prediction of functionality from RegulomeDB. The proportion of rare variants at polycomb repressive chromatin state at relevant tissues was higher in cases than in controls. The proportion of rare variants with predicted regulatory role was significantly higher in cases than in controls (P=0.0028, OR=1.93, 95% C.I.=1.23-3.04). Combination of information from both sources led to the identification of an excess of carriers of rare variants with predicted regulatory role located at polycomb repressive chromatin state at relevant tissues in cases versus controls (P=0.0016, OR=19.34, 95% C.I.=2.45-2495.26). The variants are located at two genes affected by the 17q12 copy number variant, LHX1 and HNF1B. These data strongly suggest that a specific epigenetic mechanism, chromatin remodeling by histone modification during early development, may be impaired in a subset of schizophrenia patients, in agreement with previous data.

  11. RNA sequencing of the exercise transcriptome in equine athletes.

    Stefano Capomaccio

    Full Text Available The horse is an optimal model organism for studying the genomic response to exercise-induced stress, due to its natural aptitude for athletic performance and the relative homogeneity of its genetic and environmental backgrounds. Here, we applied RNA-sequencing analysis through the use of SOLiD technology in an experimental framework centered on exercise-induced stress during endurance races in equine athletes. We monitored the transcriptional landscape by comparing gene expression levels between animals at rest and after competition. Overall, we observed a shift from coding to non-coding regions, suggesting that the stress response involves the differential expression of not annotated regions. Notably, we observed significant post-race increases of reads that correspond to repeats, especially the intergenic and intronic L1 and L2 transposable elements. We also observed increased expression of the antisense strands compared to the sense strands in intronic and regulatory regions (1 kb up- and downstream of the genes, suggesting that antisense transcription could be one of the main mechanisms for transposon regulation in the horse under stress conditions. We identified a large number of transcripts corresponding to intergenic and intronic regions putatively associated with new transcriptional elements. Gene expression and pathway analysis allowed us to identify several biological processes and molecular functions that may be involved with exercise-induced stress. Ontology clustering reflected mechanisms that are already known to be stress activated (e.g., chemokine-type cytokines, Toll-like receptors, and kinases, as well as "nucleic acid binding" and "signal transduction activity" functions. There was also a general and transient decrease in the global rates of protein synthesis, which would be expected after strenuous global stress. In sum, our network analysis points toward the involvement of specific gene clusters in equine exercise

    A Gram-stain-negative and orangish yellow-pigmented bacterial strain, designated PR1014K T , was isolated from an automobile evaporator core collected in Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain PR1014K T was related with the members of the genus Spirosoma (94.7-90.2%) and closely related with Spirosoma lacussanchae CPCC 100624 T (94.7%), Spirosoma knui 15J8-12 T (94.3%), and Spirosoma soli MIMBbqt12 T (93.3%). The strain grew at 15-40°C (optimum, 25°C), pH 6.5-7.0 (optimum, 6.5) and 0-1% (w/v) NaCl (optimum, 0%). The predominant fatty acids were summed feature 3 (C 16:1 ω7c and/or C 16:1 ω6c), C 16:0 , iso-C 15:0 , C 16:1 ω5c, and iso-C 17:0 3-OH. The major menaquinone was MK-7. The polar lipid profile of the strain indicated that the presence of one phosphatidylethanolamine, one unidentified aminolipid, two unidentified aminophospholipids, and three unidentified lipids. The DNA G+C content of the strain was 47.4 mol%. On the basis of the phenotypic, genotypic and chemotaxonomic characteristics, strain PR1014K T represents a novel species in the genus Spirosoma, for which the name Spirosoma metallicus sp. nov.

    A Gram-reaction-negative, aerobic, motile, rod-shaped, arsenite [As(III)]-resistant bacterium, designated strain YW8(T), was isolated from agricultural soil. 16S rRNA gene sequence analysis showed over 97% sequence similarity to strains of the environmental species Xenophilus azovorans, Xenophilus aerolatus, Simplicispira metamorpha, Variovorax soli, and Xylophilus ampelinus. However, the phylogenetic tree indicated that strain YW8(T) formed a separate clade from Xenophilus azovorans. DNA-DNA hybridization experiments showed that the DNA-DNA relatedness values between strain YW8(T) and its closest phylogenetic neighbours were below 24.2-35.5%, which clearly separated the strain from these closely related species. The major cellular fatty acids of strain YW8(T) were C(16 : 0), C(17 : 0) cyclo, C(18 : 1)ω7c, and summed feature 3(C(16 : 1)ω6c and/or C(16 : 1)ω7c). The genomic DNA G+C content was 69.3 mol%, and the major respiratory quinone was ubiquinone-8. The predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, three unknown phospholipids, an unknown polar lipid and phosphatidylserine. The major polyamines were 2-hydroxyputrescine and putrescine. On the basis of morphological, physiological and biochemical characteristics, phylogenetic position, DNA-DNA hybridization and chemotaxonomic data, strain YW8(T) is considered to represent a novel species of the genus Xenophilus, for which the name Xenophilus arseniciresistens sp. nov. is proposed; the type strain is YW8(T) ( = CCTCC AB2012103(T) = KACC 16853(T)). © 2014 IUMS.

  16. Fish the ChIPs: a pipeline for automated genomic annotation of ChIP-Seq data

    Minucci Saverio


    Full Text Available Abstract Background High-throughput sequencing is generating massive amounts of data at a pace that largely exceeds the throughput of data analysis routines. Here we introduce Fish the ChIPs (FC, a computational pipeline aimed at a broad public of users and designed to perform complete ChIP-Seq data analysis of an unlimited number of samples, thus increasing throughput, reproducibility and saving time. Results Starting from short read sequences, FC performs the following steps: 1 quality controls, 2 alignment to a reference genome, 3 peak calling, 4 genomic annotation, 5 generation of raw signal tracks for visualization on the UCSC and IGV genome browsers. FC exploits some of the fastest and most effective tools today available. Installation on a Mac platform requires very basic computational skills while configuration and usage are supported by a user-friendly graphic user interface. Alternatively, FC can be compiled from the source code on any Unix machine and then run with the possibility of customizing each single parameter through a simple configuration text file that can be generated using a dedicated user-friendly web-form. Considering the execution time, FC can be run on a desktop machine, even though the use of a computer cluster is recommended for analyses of large batches of data. FC is perfectly suited to work with data coming from Illumina Solexa Genome Analyzers or ABI SOLiD and its usage can potentially be extended to any sequencing platform. Conclusions Compared to existing tools, FC has two main advantages that make it suitable for a broad range of users. First of all, it can be installed and run by wet biologists on a Mac machine. Besides it can handle an unlimited number of samples, being convenient for large analyses. In this context, computational biologists can increase reproducibility of their ChIP-Seq data analyses while saving time for downstream analyses.

  17. The mitochondrial genome of an aquatic plant, Spirodela polyrhiza.

    Wenqin Wang

    Full Text Available BACKGROUND: Spirodela polyrhiza is a species of the order Alismatales, which represent the basal lineage of monocots with more ancestral features than the Poales. Its complete sequence of the mitochondrial (mt genome could provide clues for the understanding of the evolution of mt genomes in plant. METHODS: Spirodela polyrhiza mt genome was sequenced from total genomic DNA without physical separation of chloroplast and nuclear DNA using the SOLiD platform. Using a genome copy number sensitive assembly algorithm, the mt genome was successfully assembled. Gap closure and accuracy was determined with PCR products sequenced with the dideoxy method. CONCLUSIONS: This is the most compact monocot mitochondrial genome with 228,493 bp. A total of 57 genes encode 35 known proteins, 3 ribosomal RNAs, and 19 tRNAs that recognize 15 amino acids. There are about 600 RNA editing sites predicted and three lineage specific protein-coding-gene losses. The mitochondrial genes, pseudogenes, and other hypothetical genes (ORFs cover 71,783 bp (31.0% of the genome. Imported plastid DNA accounts for an additional 9,295 bp (4.1% of the mitochondrial DNA. Absence of transposable element sequences suggests that very few nuclear sequences have migrated into Spirodela mtDNA. Phylogenetic analysis of conserved protein-coding genes suggests that Spirodela shares the common ancestor with other monocots, but there is no obvious synteny between Spirodela and rice mtDNAs. After eliminating genes, introns, ORFs, and plastid-derived DNA, nearly four-fifths of the Spirodela mitochondrial genome is of unknown origin and function. Although it contains a similar chloroplast DNA content and range of RNA editing as other monocots, it is void of nuclear insertions, active gene loss, and comprises large regions of sequences of unknown origin in non-coding regions. Moreover, the lack of synteny with known mitochondrial genomic sequences shed new light on the early evolution of monocot

    Full Text Available Jiyan-1 puffer, the F1 hybrid of Takifugu rubripes and Takifugu flavidus, displays obvious heterosis in the growth performance, flavor and stress tolerance. In the present study, comparative analysis for the transcriptomes of T. rubripes, T. flavidus and Jiyan-1 was performed aiming to reveal the possible mechanisms of heterosis in pufferfish. Whole transcriptomes were sequenced using the SOLiD4 platform, and a total of 44,305 transcripts corresponding to 18,164 genes were identified collectively. A total of 14,148 transcripts were differentially expressed. By comparing the gene expression patterns of the three samples, the coexistence of overdominance, dominance, underdominance and additivity was observed in the gene action modes of Jiyan-1. There were 2,237 transcripts in the intersection of the differentially expressed transcripts from Jiyan-1 versus T. rubripes and Jiyan-1 versus T. flavidus, among which 213 transcripts were also in the T. rubripes versus T. flavidus. The potential functions of the remaining 2,024 transcripts were mainly associated with metabolic process, nucleotide binding and catalytic activity. The enrichment results indicated metabolism was the most activated biological function in the heterosis. In addition, 35 KEGG pathways were retrieved as affiliated with more than three differentially expressed transcripts and 8,579 potentially novel transcript isoforms were identified for Jiyan-1. The present study revealed the coexistence of multiple gene actions in the hybrid puffer, indicated the importance of metabolism, ion binding function and kinase activity, as well as provided a list of candidate genes and pathways for heterosis. It could be helpful for the better understanding of the determination and regulation mechanisms of heterosis.

  19. Pedobacter humicola sp. nov., a member of the genus Pedobacter isolated from soil. (United States)

    Dahal, Ram Hari; Kim, Jaisoo


    An aerobic, Gram-stain-negative, oxidase-negative, catalase-positive, non-motile, non-spore-forming, rod-shaped, light pink-pigmented bacterium, designated strain R135T, was isolated from soil in Hwaseong, South Korea. Flexirubin-type pigments were absent. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain R135T formed a lineage within the family Sphingobacteriaceae of the phylum Bacteroidetes. It was distinct from various species of the genus Pedobacter, including P. terrae DS-57T (98.13 % sequence similarity), P. alluvionis NWER-II11T (97.76 %), P. suwonensis 15-52T (97.71 %), P. kyungheensis KACC 16221T (97.37 %), P. roseus CG-GP80T (97.24 %), P. soli 15-51T (97.23 %) and P. sandarakinus DS-27T (97.09 %). The major isoprenoid quinone was menaquinone-7 (MK-7), and the major polar lipid was phosphatidylethanolamine. The major cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C15 : 0, iso-C17 : 0 3-OH and C16 : 0. The DNA G+C content of strain R135T was 40.4 mol%. Levels of DNA-DNA hybridization similarities between strain R135Tand other members of the genus Pedobacter ranged from 25 % to 43 %. On the basis of phenotypic, genotypic and phylogenetic analysis, strain R135T represents a novel species of the genus Pedobacter, for which the name Pedobacter humicola sp. nov. is proposed. The type strain is R135T (=KEMB 9005-332T=KACC 18452T=JCM 31010T).

  20. Proposal of Mucilaginibacter phyllosphaerae sp. nov. isolated from the phyllosphere of Galium album. (United States)

    Aydogan, Ebru L; Busse, Hans-Jürgen; Moser, Gerald; Müller, Christoph; Kämpfer, Peter; Glaeser, Stefanie P


    A pink-pigmented, Gram-stain-negative, rod-shaped, non-spore-forming bacterial strain, PP-F2F-G21T, was isolated from the phyllosphere of Galium album. Phylogenetic analysis of the nearly full-length 16S rRNA gene sequence of strain PP-F2F-G21T showed the closest relationship to type strains of the species Mucilaginibacter lutimaris (97.7 %), Mucilaginibacter soli (97.3 %) and Mucilaginibacter rigui (97.1 %). Sequence similarities to all other type strains were below 97 %. The predominant cellular fatty acids of strain PP-F2F-G21T are C16 : 1 ω7c/iso-C15 : 0 2-OH (measured as summed feature 3 fatty acids) and iso-C15 : 0 followed by iso-C17 : 0 3-OH, C16 : 1 ω5c and C16 : 0. The major compound in the polyamine pattern was sym-homospermidine and the diamino acid of the peptidoglycan was meso-diaminopimelic acid. The quinone system was exclusively composed of menaquinone MK-7. The polar lipid profile contained the major lipid phosphatidylethanolamine and in addition 18 unidentified lipids. Based on phylogenetic, chemotaxonomic and phenotypic analyses, we propose a novel species of the genus Mucilaginibacter named Mucilaginibacter phyllosphaeraesp. nov. The type strain is PP-F2F-G21T (=CCM 8625T=CIP 110921T=LMG 29118T).

    Full Text Available Nell’articolo si descrivono le recenti trasformazioni urbane della città di Istanbul in Turchia in relazione all’implementazione di aree pedonali e all’utilizzo di mobilità dolce. Il sistema trasportistico è stato ampliato ed integrato di recente ed in tempi molto brevi: nei soli ultimi due anni è stata potenziata la linea tranviaria, sono state inaugurate una funicolare ed una teleferica ed è stata realizzata una stazione di interscambio gomma-ferro, ponendo grande attenzione all’integrazione del trasporto su ferro e/o gomma con la mobilità pedonale. Allo stesso modo sono state implementate le linee marittime che collegano le diverse sponde della città ed integrate alle linee su ferro e su gomma. Lo sviluppo e la riqualificazione della città sono dunque stati guidati dalla trasformazione del sistema trasportistico che ha rappresentato il vero motore della riqualificazione urbana. L’antico quartiere di Sultanahmet è stato interamente riqualificato e collegato, attraverso la linea tranviaria veloce che lo attraversa interamente, al resto della città fino ai quartieri più periferici. Allo stesso modo nel quartiere di Beyoglu che, dopo l’indipendenza era caduto in totale rovina, ha riacquistato l’antica eleganza che lo connotava. Il viale dell’Indipendenza (antica Rue De Pera che attraversa tutto il quartiere è stato reso pedonale e con un tram vintage che percorre tutto il viale sono stati collegati il nodo di interscambio Taksim, dotato di metropolitana e funicolare, con il nodo di interscambio Tünel, dotato di tram veloce e trasporto su gomma. Nell’articolo si è inteso evidenziare come la riqualificazione urbana della città sia stata guidata da interventi integrati trasporto/territorio e come i risultati ottenuti, nel caso-studio, siano stati anche il frutto di politiche attente alla sicurezza sociale.

  2. La gestione dei flussi turistici tramite sistemi di trasporto innovativi: l’esempio di Perugia

    Leonardo Naldini


    Full Text Available La città di Perugia ha, fin dagli anni ’70, unito alla sua capacità di attrazione turistica, dovuta al patrimonio storico ambientale plurimillenario, una volontà di affrontare il tema della mobilità urbana in maniera profondamente innovativa ed ambientalmente sostenibile. Il concetto della creazione di parcheggi di attestazione, serviti da percorsi meccanizzati di risalita verso l’acropoli, è stato recentemente ampliato dalla creazione del Minimetro, mezzo di trasporto innovativo, dal ridottissimo impatto ambientale, che unisce in soli 12 minuti, con un servizio semicontinuo, l’area di valle di Pian di Massiano, dotata di un capace parcheggio da circa 2800 posti auto, al centro cittadino, servendo diversi quartieri urbani. Tale sistema di trasporto, corridoio forte del trasporto pubblico urbano, ha fornito lo spunto per attuare una nuova modalità di gestione dei flussi turistici, che individua nel Minimetro la modalità principale di accesso al centro storico sia per i gruppi a numero ridotto, sia per i gruppi organizzati in arrivo con i bus turistici. L’organizzazione della mobilità turistica che ne è derivata costituisce un ulteriore passo in avanti lungo quell’itinerario di gestione della città che cerca di coniugare l’attrattiva turistica, con le sue ricadute in termini di crescita economica, e la salvaguardia del patrimonio storico artistico e della qualità della vita dei cittadini. Gli scenari futuri vedono un’iniezione di tecnologia in questo contesto, con l’introduzione nella gestione dei flussi turistici dei concetti di accreditamento, dell’infomobilità come supporto alle politiche urbane, del controllo unito alla fornitura di servizi georeferenziati.

  3. Genome and Transcriptome Sequencing of the Ostreid herpesvirus 1 From Tomales Bay, California (United States)

    Burge, C. A.; Langevin, S.; Closek, C. J.; Roberts, S. B.; Friedman, C. S.


    Mass mortalities of larval and seed bivalve molluscs attributed to the Ostreid herpesvirus 1 (OsHV-1) occur globally. OsHV-1 was fully sequenced and characterized as a member of the Family Malacoherpesviridae. Multiple strains of OsHV-1 exist and may vary in virulence, i.e. OsHV-1 µvar. For most global variants of OsHV-1, sequence data is limited to PCR-based sequencing of segments, including two recent genomes. In the United States, OsHV-1 is limited to detection in adjacent embayments in California, Tomales and Drakes bays. Limited DNA sequence data of OsHV-1 infecting oysters in Tomales Bay indicates the virus detected in Tomales Bay is similar but not identical to any one global variant of OsHV-1. In order to better understand both strain variation and virulence of OsHV-1 infecting oysters in Tomales Bay, we used genomic and transcriptomic sequencing. Meta-genomic sequencing (Illumina MiSeq) was conducted from infected oysters (n=4 per year) collected in 2003, 2007, and 2014, where full OsHV-1 genome sequences and low overall microbial diversity were achieved from highly infected oysters. Increased microbial diversity was detected in three of four samples sequenced from 2003, where qPCR based genome copy numbers of OsHV-1 were lower. Expression analysis (SOLiD RNA sequencing) of OsHV-1 genes expressed in oyster larvae at 24 hours post exposure revealed a nearly complete transcriptome, with several highly expressed genes, which are similar to recent transcriptomic analyses of other OsHV-1 variants. Taken together, our results indicate that genome and transcriptome sequencing may be powerful tools in understanding both strain variation and virulence of non-culturable marine viruses.

  4. Bioremediation of diuron contaminated soils by a novel degrading microbial consortium. (United States)

    Villaverde, J; Rubio-Bellido, M; Merchán, F; Morillo, E


    Diuron is a biologically active pollutant present in soil, water and sediments. It is persistent in soil, water and groundwater and slightly toxic to mammals and birds as well as moderately toxic to aquatic invertebrates. Its principal product of biodegradation, 3,4-dichloroaniline, exhibits a higher toxicity than diuron and is also persistent in the environment. On this basis, the objective of the study was to determine the potential capacity of a proposed novel diuron-degrading microbial consortium (DMC) for achieving not only diuron degradation, but its mineralisation both in solution as well as in soils with different properties. The consortium was tested in a soil solution where diuron was the only carbon source, and more than 98.8% of the diuron initially added was mineralised after only a few days. The consortium was composed of three diuron-degrading strains, Arthrobacter sulfonivorans, Variovorax soli and Advenella sp. JRO, the latter had been isolated in our laboratory from a highly contaminated industrial site. This work shows for the first time the potential capacity of a member of the genus Advenella to remediate pesticide-contaminated soils. However, neither of the three strains separately achieved mineralisation (ring- 14 C) of diuron in a mineral medium (MSM) with a trace nutrient solution (NS); combined in pairs, they mineralised 40% of diuron in solution, but the most relevant result was obtained in the presence of the three-member consortium, where complete diuron mineralisation was achieved after only a few days. In the presence of the investigated soils in suspension, the capacity of the consortium to mineralise diuron was evaluated, achieving mineralisation of a wide range of herbicides from 22.9 to 69.0%.

  5. Development of prediction model and experimental validation in predicting the curcumin content of turmeric (Curcuma longa L.

    Directory of Open Access Journals (Sweden)

    Abdul Akbar


    Full Text Available The drug yielding potential of turmeric (Curcuma longa L. is largely due to the presence of phyto-constituent ‘curcumin’. Curcumin has been found to possess a myriad of therapeutic activities ranging from anti-inflammatory to neuroprotective. Lack of requisite high curcumin containing genotypes and variation in the curcumin content of turmeric at different agro climatic regions are the major stumbling blocks in commercial production of turmeric. Curcumin content of turmeric is greatly influenced by environmental factors. Hence, a prediction model based on artificial neural network (ANN was developed to map genome environment interaction basing on curcumin content, soli and climatic factors from different agroclimatic regions for prediction of maximum curcumin content at various sites to facilitate the selection of suitable region for commercial cultivation of turmeric. The ANN model was developed and tested using a data set of 119 generated by collecting samples from 8 different agroclimatic regions of Odisha. The curcumin content from these samples was measured that varied from 7.2% to 0.4%. The ANN model was trained with 11 parameters of soil and climatic factors as input and curcumin content as output. The results showed that feed-forward ANN model with 8 nodes (MLFN-8 was the most suitable one with R2 value of 0.91. Sensitivity analysis revealed that minimum relative humidity, altitude, soil nitrogen content and soil pH had greater effect on curcumin content. This ANN model has shown proven efficiency for predicting and optimizing the curcumin content at a specific site.

  6. Rhodanobacter glycinis sp. nov., a yellow-pigmented gammaproteobacterium isolated from the rhizoplane of field-grown soybean. (United States)

    Madhaiyan, Munusamy; Poonguzhali, Selvaraj; Saravanan, Venkatakrishnan Sivaraj; Kwon, Soon-Wo


    A novel, yellow-pigmented bacterium, designated strain MO64(T), was isolated from the rhizoplane of field-grown soybean, collected from an experimental plot at Coimbatore, India. Cells were Gram-reaction-negative, motile, non-spore-forming rods that produced yellow-pigmented colonies on R2A agar. Phylogenetic analysis, based on 16S rRNA gene sequences, showed that strain MO64(T) belonged to the genus Rhodanobacter. Strain MO64(T) was related most closely to Rhodanobacter ginsengisoli GR17-7(T) (98.0% 16S rRNA gene sequence similarity), Rhodanobacter spathiphylli B39(T) (97.9%), Rhodanobacter panaciterrae LnR5-47(T) (97.7%), Rhodanobacter terrae GP18-1(T) (97.6%), Rhodanobacter soli DCY45(T) (97.3%) and Rhodanobacter caeni MJ01(T) (97.2%); levels of similarity to the type strains of all other recognized species of the genus Rhodanobacter were less than 97.0%. Chemotaxonomic data (Q-8 as the predominant ubiquinone, and iso-C(16 : 0), iso-C(15 : 0), C(17 : 0) cyclo, iso-C(17 : 1)ω9c, iso-C(17 : 0) and iso-C(11 : 0) as the major fatty acids) also supported the affiliation of strain MO64(T) with the genus Rhodanobacter. The G+C content of the genomic DNA was 64 mol%. The results of DNA-DNA hybridization and phenotypic analysis showed that strain MO64(T) can be distinguished from all known species of the genus Rhodanobacter and therefore represents a novel species of the genus, for which the name Rhodanobacter glycinis sp. nov. is proposed. The type strain is MO64(T) ( = ICMP 17626(T) = NBRC 105007(T)). © 2014 IUMS.

  7. Shotgun metagenomic data reveals signifcant abundance but low diversity of Candidatus Scalindua marine anammox bacteria in the Arabian Sea oxygen minimum zone

    laura eVillanueva


    Full Text Available Anaerobic ammonium oxidizing (anammox bacteria are responsible for a significant portion of the loss of fixed nitrogen from the oceans, making them important players in the global nitrogen cycle. To date, marine anammox bacteria found in both water columns and sediments worldwide belong almost exclusively to Candidatus Scalindua species. Recently the genome assembly of a marine anammox enrichment culture dominated by Candidatus Scalindua profunda became available and can now be used as a template to study metagenome data obtained from various oxygen minimum zones. Here, we sequenced genomic DNA from suspended particulate matter recovered at the upper (170 m deep and center (600 m area of the oxygen minimum zone in the Arabian Sea by SOLiD and Ion Torrent technology. The genome of Candidatus Scalindua profunda served as a template to collect reads. Based on the mapped reads marine anammox Abundance was estimated to be at least 0.4% in the upper and 1.7% in the center area. Single nucleotide variation (SNV analysis was performed to assess diversity of the Candidatus Scalindua populations. Most highly covered were the two diagnostic anammox genes hydrazine synthase (scal_01318c, hzsA and hydrazine dehydrogenase (scal_03295, hdh, while other genes involved in anammox metabolism (narGH, nirS, amtB, focA and ACS had a lower coverage but could still be assembled and analyzed. The results show that Candidatus Scalindua is abundantly present in the Arabian Sea OMZ, but that the diversity within the ecosystem is relatively low.

    Full Text Available Usher syndrome (USH is a clinically and genetically heterogeneous disorder characterized by visual and hearing impairments. Clinically, it is subdivided into three subclasses with nine genes identified so far. In the present study, we investigated whether the currently available Next Generation Sequencing (NGS technologies are already suitable for molecular diagnostics of USH. We analyzed a total of 12 patients, most of which were negative for previously described mutations in known USH genes upon primer extension-based microarray genotyping. We enriched the NGS template either by whole exome capture or by Long-PCR of the known USH genes. The main NGS sequencing platforms were used: SOLiD for whole exome sequencing, Illumina (Genome Analyzer II and Roche 454 (GS FLX for the Long-PCR sequencing. Long-PCR targeting was more efficient with up to 94% of USH gene regions displaying an overall coverage higher than 25×, whereas whole exome sequencing yielded a similar coverage for only 50% of those regions. Overall this integrated analysis led to the identification of 11 novel sequence variations in USH genes (2 homozygous and 9 heterozygous out of 18 detected. However, at least two cases were not genetically solved. Our result highlights the current limitations in the diagnostic use of NGS for USH patients. The limit for whole exome sequencing is linked to the need of a strong coverage and to the correct interpretation of sequence variations with a non obvious, pathogenic role, whereas the targeted approach suffers from the high genetic heterogeneity of USH that may be also caused by the presence of additional causative genes yet to be identified.

    Wang, A. H.; Wu, S. T.; Tandberg-Hanssen, E.; Hill, Frank


    Magnetic field measurements, line of sight (LOS) and/or vector magnetograms, have been used in a variety of solar physics studies. Currently, the global transverse velocity measurements near the photosphere from the Global Oscillation Network Group (GONG) are available. We have utilized these multiple observational data, for the first time, to present a data-driven global three-dimensional and resistive magnetohydrodynamic (MHD) simulation, and to investigate the energy transport across the photosphere to the corona. The measurements of the LOS magnetic field and transverse velocity reflect the effects of convective zone dynamics and provide information from the sub-photosphere to the corona. In order to self-consistently include the observables on the lower boundary as the inputs to drive the model, a set of time-dependent boundary conditions is derived by using the method of characteristics. We selected GONG's global transverse velocity measurements of synoptic chart CR2009 near the photosphere and SOLIS full-resolution LOS magnetic field maps of synoptic chart CR2009 on the photosphere to simulate the equilibrium state and compute the energy transport across the photosphere. To show the advantage of using both observed magnetic field and transverse velocity data, we have studied two cases: (1) with the inputs of the LOS magnetic field and transverse velocity measurements, and (2) with the input of the LOS magnetic field and without the input of transverse velocity measurements. For these two cases, the simulation results presented here are a three-dimensional coronal magnetic field configuration, density distributions on the photosphere and at 1.5 solar radii, and the solar wind in the corona. The deduced physical characteristics are the total current helicity and the synthetic emission. By comparing all the physical parameters of case 1 and case 2 and their synthetic emission images with the EIT image, we find that using both the measured magnetic field and the

    Current efforts to understand antibiotic resistance on the whole genome scale tend to focus on known genes even as high throughput sequencing strategies uncover novel mechanisms. To identify genomic variations associated with antibiotic resistance, we employed a modified genome-wide association study; we sequenced genomic DNA from pools of E. coli clinical isolates with similar antibiotic resistance phenotypes using SOLiD technology to uncover single nucleotide polymorphisms (SNPs) unanimously conserved in each pool. The multidrug-resistant pools were genotypically similar to SMS-3-5, a previously sequenced multidrug-resistant isolate from a polluted environment. The similarity was evenly spread across the entire genome and not limited to plasmid or pathogenicity island loci. Among the pools of clinical isolates, genomic variation was concentrated adjacent to previously reported inversion and duplication differences between the SMS-3-5 isolate and the drug-susceptible laboratory strain, DH10B. SNPs that result in non-synonymous changes in gyrA (encoding the well-known S83L allele associated with fluoroquinolone resistance), mutM, ligB, and recG were unanimously conserved in every fluoroquinolone-resistant pool. Alleles of the latter three genes are tightly linked among most sequenced E. coli genomes, and had not been implicated in antibiotic resistance previously. The changes in these genes map to amino acid positions in alpha helices that are involved in DNA binding. Plasmid-encoded complementation of null strains with either allelic variant of mutM or ligB resulted in variable responses to ultraviolet light or hydrogen peroxide treatment as markers of induced DNA damage, indicating their importance in DNA metabolism and revealing a potential mechanism for fluoroquinolone resistance. Our approach uncovered evidence that additional DNA binding enzymes may contribute to fluoroquinolone resistance and further implicate environmental bacteria as a reservoir for

    Sylvia Cardoso Leão

    Full Text Available BACKGROUND: An extended outbreak of mycobacterial surgical infections occurred in Brazil during 2004-2008. Most infections were caused by a single strain of Mycobacterium abscessus subsp. bolletii, which was characterized by a specific rpoB sequevar and two highly similar pulsed-field gel electrophoresis (PFGE patterns differentiated by the presence of a ∼50 kb band. The nature of this band was investigated. METHODOLOGY/PRINCIPAL FINDINGS: Genomic sequencing of the prototype outbreak isolate INCQS 00594 using the SOLiD platform demonstrated the presence of a 56,267-bp [corrected] circular plasmid, designated pMAB01. Identity matrices, genetic distances and phylogeny analyses indicated that pMAB01 belongs to the broad-host-range plasmid subgroup IncP-1β and is highly related to BRA100, pJP4, pAKD33 and pB10. The presence of pMAB01-derived sequences in 41 M. abscessus subsp. bolletii isolates was evaluated using PCR, PFGE and Southern blot hybridization. Sixteen of the 41 isolates showed the presence of the plasmid. The plasmid was visualized as a ∼50-kb band using PFGE and Southern blot hybridization in 12 isolates. The remaining 25 isolates did not exhibit any evidence of this plasmid. The plasmid was successfully transferred to Escherichia coli by conjugation and transformation. Lateral transfer of pMAB01 to the high efficient plasmid transformation strain Mycobacterium smegmatis mc(2155 could not be demonstrated. CONCLUSIONS/SIGNIFICANCE: The occurrence of a broad-host-range IncP-1β plasmid in mycobacteria is reported for the first time. Thus, genetic exchange could result in the emergence of specific strains that might be better adapted to cause human disease.

  13. Integrating sequencing technologies in personal genomics: optimal low cost reconstruction of structural variants.

    Jiang Du


    Full Text Available The goal of human genome re-sequencing is obtaining an accurate assembly of an individual's genome. Recently, there has been great excitement in the development of many technologies for this (e.g. medium and short read sequencing from companies such as 454 and SOLiD, and high-density oligo-arrays from Affymetrix and NimbelGen, with even more expected to appear. The costs and sensitivities of these technologies differ considerably from each other. As an important goal of personal genomics is to reduce the cost of re-sequencing to an affordable point, it is worthwhile to consider optimally integrating technologies. Here, we build a simulation toolbox that will help us optimally combine different technologies for genome re-sequencing, especially in reconstructing large structural variants (SVs. SV reconstruction is considered the most challenging step in human genome re-sequencing. (It is sometimes even harder than de novo assembly of small genomes because of the duplications and repetitive sequences in the human genome. To this end, we formulate canonical problems that are representative of issues in reconstruction and are of small enough scale to be computationally tractable and simulatable. Using semi-realistic simulations, we show how we can combine different technologies to optimally solve the assembly at low cost. With mapability maps, our simulations efficiently handle the inhomogeneous repeat-containing structure of the human genome and the computational complexity of practical assembly algorithms. They quantitatively show how combining different read lengths is more cost-effective than using one length, how an optimal mixed sequencing strategy for reconstructing large novel SVs usually also gives accurate detection of SNPs/indels, how paired-end reads can improve reconstruction efficiency, and how adding in arrays is more efficient than just sequencing for disentangling some complex SVs. Our strategy should facilitate the sequencing of

    Full Text Available We determined the complete sequence and organization of the genome of a putative member of the genus Polerovirus tentatively named Pepper yellow leaf curl virus (PYLCV. PYLCV has a wider host range than Tobacco vein-distorting virus (TVDV and has a close serological relationship with Cucurbit aphid-borne yellows virus (CABYV (both poleroviruses. The extracted viral RNA was subjected to SOLiD next-generation sequence analysis and used as a template for reverse transcription synthesis, which was followed by PCR amplification. The ssRNA genome of PYLCV includes 6,028 nucleotides encoding six open reading frames (ORFs, which is typical of the genus Polerovirus. Comparisons of the deduced amino acid sequences of the PYLCV ORFs 2-4 and ORF5, indicate that there are high levels of similarity between these sequences to ORFs 2-4 of TVDV (84-93% and to ORF5 of CABYV (87%. Both PYLCV and Pepper vein yellowing virus (PeVYV contain sequences that point to a common ancestral polerovirus. The recombination breakpoint which is located at CABYV ORF3, which encodes the viral coat protein (CP, may explain the CABYV-like sequences found in the genomes of the pepper infecting viruses PYLCV and PeVYV.

    We determined the complete sequence and organization of the genome of a putative member of the genus Polerovirus tentatively named Pepper yellow leaf curl virus (PYLCV). PYLCV has a wider host range than Tobacco vein-distorting virus (TVDV) and has a close serological relationship with Cucurbit aphid-borne yellows virus (CABYV) (both poleroviruses). The extracted viral RNA was subjected to SOLiD next-generation sequence analysis and used as a template for reverse transcription synthesis, which was followed by PCR amplification. The ssRNA genome of PYLCV includes 6,028 nucleotides encoding six open reading frames (ORFs), which is typical of the genus Polerovirus. Comparisons of the deduced amino acid sequences of the PYLCV ORFs 2-4 and ORF5, indicate that there are high levels of similarity between these sequences to ORFs 2-4 of TVDV (84-93%) and to ORF5 of CABYV (87%). Both PYLCV and Pepper vein yellowing virus (PeVYV) contain sequences that point to a common ancestral polerovirus. The recombination breakpoint which is located at CABYV ORF3, which encodes the viral coat protein (CP), may explain the CABYV-like sequences found in the genomes of the pepper infecting viruses PYLCV and PeVYV. Two additional regions unique to PYLCV (PY1 and PY2) were identified between nucleotides 4,962 and 5,061 (ORF 5) and between positions 5,866 and 6,028 in the 3' NCR. Sequence analysis of the pepper-infecting PeVYV revealed three unique regions (Pe1-Pe3) with no similarity to other members of the genus Polerovirus. Genomic analyses of PYLCV and PeVYV suggest that the speciation of these viruses occurred through putative recombination event(s) between poleroviruses co-infecting a common host(s), resulting in the emergence of PYLCV, a novel pathogen with a wider host range.

  16. Evaluation of biostimulation and Tween 80 addition for the bioremediation of long-term DDT-contaminated soil. (United States)

    Betancur-Corredor, Bibiana; Pino, Nancy J; Cardona, Santiago; Peñuela, Gustavo A


    The bioremediation of a long-term contaminated soil through biostimulation and surfactant addition was evaluated. The concentrations of 1,1,1-trichloro-2,2-bis(4-chlorophenyl) ethane (DDT) and its metabolites 1,1-dichloro-2,2-bis(4-chlorophenyl) ethane (DDD) and 1,1-dichloro-2,2-bis(4-chlorophenyl) ethylene (DDE) were monitored during an 8-week remediation process. Physicochemical characterization of the treated soil was performed before and after the bioremediation process. The isolation and identification of predominant microorganisms during the remediation process were also carried out. The efficiency of detoxification was evaluated after each bioremediation protocol. Humidity and pH and the heterotrophic microorganism count were monitored weekly. The DDT concentration was reduced by 79% after 8 weeks via biostimulation with surfactant addition (B+S) and 94.3% via biostimulation alone (B). Likewise, the concentrations of the metabolites DDE and DDD were reduced to levels below the quantification limits. The microorganisms isolated during bioremediation were identified as Bacillus thuringiensis, Flavobacterium sp., Cuprivadius sp., Variovorax soli, Phenylobacterium sp. and Lysobacter sp., among others. Analysis with scanning electron microscopy (SEM) allowed visualization of the colonization patterns of soil particles. The toxicity of the soil before and after bioremediation was evaluated using Vibrio fischeri as a bioluminescent sensor. A decrease in the toxic potential of the soil was verified by the increase of the concentration/effect relationship EC50 to 26.9% and 27.2% for B+S and B, respectively, compared to 0.4% obtained for the soil before treatment and 2.5% by natural attenuation after 8 weeks of treatment.

    Kumsa, Bersissa; Socolovschi, Cristina; Parola, Philippe; Rolain, Jean-Marc; Raoult, Didier


    This study was conducted to determine the presence of Acinetobacter and Rickettsia species DNA in lice and Melophagus ovinus (sheep ked) of animals from Oromia Regional State in Ethiopia. From September through November 2011, a total of 207 cattle, 85 sheep, 47 dogs and 16 cats were examined for ectoparasites. Results of morphological identification revealed several species of ectoparasites: Linognathus vituli (L. vituli), Bovicola bovis (B. bovis) and Solenopotes capillatus (S. capillatus) on cattle; B. ovis and Melophagus ovinus (M. ovinus) on sheep; and Heterodoxus spiniger (H. spiniger) on dogs. There was a significantly (p≤0.0001) higher prevalence of L. vituli observed in cattle than both S. capillatus and B. bovis. Molecular identification of lice using an 18S rRNA gene analysis confirms the identified lice species by morphological methods. We detected different Acinetobacter species among lice (11.1%) and keds (86.4%) including A. soli in L. vituli of cattle, A. lowffii in M. ovinus of sheep, A. pittii in H. spiniger of dogs, 1 new Acinetobacter spp. in M. ovinus and 2 new Acinetobacter spp. in H. spiniger of dogs using partial rpoB gene sequence analysis. There was a significantly higher prevalence of Acinetobacter spp. in keds than in lice (p≤0.00001). Higher percentage of Acinetobacter spp. DNA was detected in H. spiniger than in both B. ovis and L. vituli (p≤0.00001). Carbapenemase resistance encoding genes for blaOXA-23, blaOXA-24, blaOXA-58, blaNDM-1 and blaOXA-51 were not found in any lice and keds. These findings suggest that synanthropic animals and their ectoparasites might increase the risk of human exposure to zoonotic pathogens and could be a source for Acinetobacter spp. infections in humans. However, additional epidemiological data are required to determine whether ectoparasites of animals can act as environmental reservoirs and play a role in spreading these bacteria to both animal and human hosts.

    Stothard Paul


    Full Text Available Abstract Background One of the goals of livestock genomics research is to identify the genetic differences responsible for variation in phenotypic traits, particularly those of economic importance. Characterizing the genetic variation in livestock species is an important step towards linking genes or genomic regions with phenotypes. The completion of the bovine genome sequence and recent advances in DNA sequencing technology allow for in-depth characterization of the genetic variations present in cattle. Here we describe the whole-genome resequencing of two Bos taurus bulls from distinct breeds for the purpose of identifying and annotating novel forms of genetic variation in cattle. Results The genomes of a Black Angus bull and a Holstein bull were sequenced to 22-fold and 19-fold coverage, respectively, using the ABI SOLiD system. Comparisons of the sequences with the Btau4.0 reference assembly yielded 7 million single nucleotide polymorphisms (SNPs, 24% of which were identified in both animals. Of the total SNPs found in Holstein, Black Angus, and in both animals, 81%, 81%, and 75% respectively are novel. In-depth annotations of the data identified more than 16 thousand distinct non-synonymous SNPs (85% novel between the two datasets. Alignments between the SNP-altered proteins and orthologues from numerous species indicate that many of the SNPs alter well-conserved amino acids. Several SNPs predicted to create or remove stop codons were also found. A comparison between the sequencing SNPs and genotyping results from the BovineHD high-density genotyping chip indicates a detection rate of 91% for homozygous SNPs and 81% for heterozygous SNPs. The false positive rate is estimated to be about 2% for both the Black Angus and Holstein SNP sets, based on follow-up genotyping of 422 and 427 SNPs, respectively. Comparisons of read depth between the two bulls along the reference assembly identified 790 putative copy-number variations (CNVs. Ten

  20. Comprehensive Assessments of RNA-seq by the SEQC Consortium: FDA-Led Efforts Advance Precision Medicine

    Joshua Xu


    Full Text Available Studies on gene expression in response to therapy have led to the discovery of pharmacogenomics biomarkers and advances in precision medicine. Whole transcriptome sequencing (RNA-seq is an emerging tool for profiling gene expression and has received wide adoption in the biomedical research community. However, its value in regulatory decision making requires rigorous assessment and consensus between various stakeholders, including the research community, regulatory agencies, and industry. The FDA-led SEquencing Quality Control (SEQC consortium has made considerable progress in this direction, and is the subject of this review. Specifically, three RNA-seq platforms (Illumina HiSeq, Life Technologies SOLiD, and Roche 454 were extensively evaluated at multiple sites to assess cross-site and cross-platform reproducibility. The results demonstrated that relative gene expression measurements were consistently comparable across labs and platforms, but not so for the measurement of absolute expression levels. As part of the quality evaluation several studies were included to evaluate the utility of RNA-seq in clinical settings and safety assessment. The neuroblastoma study profiled tumor samples from 498 pediatric neuroblastoma patients by both microarray and RNA-seq. RNA-seq offers more utilities than microarray in determining the transcriptomic characteristics of cancer. However, RNA-seq and microarray-based models were comparable in clinical endpoint prediction, even when including additional features unique to RNA-seq beyond gene expression. The toxicogenomics study compared microarray and RNA-seq profiles of the liver samples from rats exposed to 27 different chemicals representing multiple toxicity modes of action. Cross-platform concordance was dependent on chemical treatment and transcript abundance. Though both RNA-seq and microarray are suitable for developing gene expression based predictive models with comparable prediction performance, RNA

  2. Whole-exome sequencing of a rare case of familial childhood acute lymphoblastic leukemia reveals putative predisposing mutations in Fanconi anemia genes. (United States)

    Spinella, Jean-François; Healy, Jasmine; Saillour, Virginie; Richer, Chantal; Cassart, Pauline; Ouimet, Manon; Sinnett, Daniel


    Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer. While the multi-step model of pediatric leukemogenesis suggests interplay between constitutional and somatic genomes, the role of inherited genetic variability remains largely undescribed. Nonsyndromic familial ALL, although extremely rare, provides the ideal setting to study inherited contributions to ALL. Toward this goal, we sequenced the exomes of a childhood ALL family consisting of mother, father and two non-twinned siblings diagnosed with concordant pre-B hyperdiploid ALL and previously shown to have inherited a rare form of PRDM9, a histone H3 methyltransferase involved in crossing-over at recombination hotspots and Holliday junctions. We postulated that inheritance of additional rare disadvantaging variants in predisposing cancer genes could affect genomic stability and lead to increased risk of hyperdiploid ALL within this family. Whole exomes were captured using Agilent's SureSelect kit and sequenced on the Life Technologies SOLiD System. We applied a data reduction strategy to identify candidate variants shared by both affected siblings. Under a recessive disease model, we focused on rare non-synonymous or frame-shift variants in leukemia predisposing pathways. Though the family was nonsyndromic, we identified a combination of rare variants in Fanconi anemia (FA) genes FANCP/SLX4 (compound heterozygote - rs137976282/rs79842542) and FANCA (rs61753269) and a rare homozygous variant in the Holliday junction resolvase GEN1 (rs16981869). These variants, predicted to affect protein function, were previously identified in familial breast cancer cases. Based on our in-house database of 369 childhood ALL exomes, the sibs were the only patients to carry this particularly rare combination and only a single hyperdiploid patient was heterozygote at both FANCP/SLX4 positions, while no FANCA variant allele carriers were identified. FANCA is the most commonly mutated gene in FA and is essential for

    Vladimir Y Ovchinnikov


    Full Text Available Opisthorchis felineus, O. viverrini, and Clonorchis sinensis (family Opisthorchiidae are parasitic flatworms that pose a serious threat to humans in some countries and cause opisthorchiasis/clonorchiasis. Chronic disease may lead to a risk of carcinogenesis in the biliary ducts. MicroRNAs (miRNAs are small noncoding RNAs that control gene expression at post-transcriptional level and are implicated in the regulation of various cellular processes during the parasite- host interplay. However, to date, the miRNAs of opisthorchiid flukes, in particular those essential for maintaining their complex biology and parasitic mode of existence, have not been satisfactorily described.Using a SOLiD deep sequencing-bioinformatic approach, we identified 43 novel and 18 conserved miRNAs for O. felineus (miracidia, metacercariae and adult worms, 20 novel and 16 conserved miRNAs for O. viverrini (adult worms, and 33 novel and 18 conserved miRNAs for C. sinensis (adult worms. The analysis of the data revealed differences in the expression level of conserved miRNAs among the three species and among three the developmental stages of O. felineus. Analysis of miRNA genes revealed two gene clusters, one cluster-like region and one intronic miRNA in the genome. The presence and structure of the two gene clusters were validated using a PCR-based approach in the three flukes.This study represents a comprehensive description of miRNAs in three members of the family Opistorchiidae, significantly expands our knowledge of miRNAs in multicellular parasites and provides a basis for understanding the structural and functional evolution of miRNAs in these metazoan parasites. Results of this study also provides novel resources for deeper understanding the complex parasite biology, for further research on the pathogenesis and molecular events of disease induced by the liver flukes. The present data may also facilitate the development of novel approaches for the prevention and

    The COSMO is a facility dedicated to observing coronal and chromospheric magnetic fields. It will be located on a mountaintop in the Hawaiian Islands and will replace the current Mauna Loa Solar Observatory (MLSO). COSMO will provide unique observations of the global coronal magnetic fields and its environment to enhance the value of data collected by other observatories on the ground (e.g. SOLIS, BBO NST, Gregor, ATST, EST, Chinese Giant Solar Telescope, NLST, FASR) and in space (e.g. SDO, Hinode, SOHO, GOES, STEREO, Solar-C, Solar Probe+, Solar Orbiter). COSMO will employ a fleet of instruments to cover many aspects of measuring magnetic fields in the solar atmosphere. The dynamics and energy flow in the corona are dominated by magnetic fields. To understand the formation of CMEs, their relation to other forms of solar activity, and their progression out into the solar wind requires measurements of coronal magnetic fields. The large aperture coronagraph, the Chromospheric and Prominence Magnetometer and the K-Coronagraph form the COSMO instrument suite to measure magnetic fields and the polarization brightness of the low corona used to infer electron density. The large aperture coronagraph will employ a 1.5 meter fuse silica singlet lens, birefringent filters, and a spectropolarimeter to cover fields of view of up to 1 degree. It will observe the corona over a wide range of emission lines from 530.3 nm through 1083.0 nm allowing for magnetic field measurements over a wide range of coronal temperatures (e.g. FeXIV at 530.3 nm, Fe X at 637.4 nm, Fe XIII at 1074.7 and 1079.8 nm. These lines are faint and require the very large aperture. NCAR and NSF have provided funding to bring the large aperture coronagraph to a preliminary design review state by the end of 2013. As with all data from Mauna Loa, the data products from COSMO will be available to the community via the Mauna Loa website:

The role of microRNA during this transition has not been systematically studied.For initial screening, total RNA from 5 GERD and 6 BE patients was size fractionated. RNA <70 nucleotides was subjected to SOLiD 3 library preparation and next generation sequencing (NGS. Bioinformatics analysis was performed using R package "DEseq". A p value<0.05 adjusted for a false discovery rate of 5% was considered significant. NGS-identified miRNA were validated using qRT-PCR in an independent group of 40 GERD and 27 BE patients. MicroRNA expression of human BE tissues was also compared with three BE cell lines.NGS detected 19.6 million raw reads per sample. 53.1% of filtered reads mapped to miRBase version 18. NGS analysis followed by qRT-PCR validation found 10 differentially expressed miRNA; several are novel (-708-5p, -944, -224-5p and -3065-5p. Up- or down- regulation predicted by NGS was matched by qRT-PCR in every case. Human BE tissues and BE cell lines showed a high degree of concordance (70-80% in miRNA expression. Prediction analysis identified targets that mapped to developmental signaling pathways such as TGFβ and Notch and inflammatory pathways such as toll-like receptor signaling and TGFβ. Cluster analysis found similarly regulated (up or down miRNA to share common targets suggesting coordination between miRNA.Using highly sensitive next-generation sequencing, we have performed a comprehensive genome wide analysis of microRNA in BE and GERD patients. Differentially expressed miRNA between BE and GERD have been further validated. Expression of miRNA between BE human tissues and BE cell lines are highly correlated. These miRNA should be studied in biological models to further understand BE development.

  7. Whole-exome sequencing identifies novel compound heterozygous mutations in USH2A in Spanish patients with autosomal recessive retinitis pigmentosa. (United States)

    Retinitis pigmentosa (RP) is an inherited retinal dystrophy characterized by extreme genetic and clinical heterogeneity. Thus, the diagnosis is not always easily performed due to phenotypic and genetic overlap. Current clinical practices have focused on the systematic evaluation of a set of known genes for each phenotype, but this approach may fail in patients with inaccurate diagnosis or infrequent genetic cause. In the present study, we investigated the genetic cause of autosomal recessive RP (arRP) in a Spanish family in which the causal mutation has not yet been identified with primer extension technology and resequencing. We designed a whole-exome sequencing (WES)-based approach using NimbleGen SeqCap EZ Exome V3 sample preparation kit and the SOLiD 5500×l next-generation sequencing platform. We sequenced the exomes of both unaffected parents and two affected siblings. Exome analysis resulted in the identification of 43,204 variants in the index patient. All variants passing filter criteria were validated with Sanger sequencing to confirm familial segregation and absence in the control population. In silico prediction tools were used to determine mutational impact on protein function and the structure of the identified variants. Novel Usher syndrome type 2A (USH2A) compound heterozygous mutations, c.4325T>C (p.F1442S) and c.15188T>G (p.L5063R), located in exons 20 and 70, respectively, were identified as probable causative mutations for RP in this family. Family segregation of the variants showed the presence of both mutations in all affected members and in two siblings who were apparently asymptomatic at the time of family ascertainment. Clinical reassessment confirmed the diagnosis of RP in these patients. Using WES, we identified two heterozygous novel mutations in USH2A as the most likely disease-causing variants in a Spanish family diagnosed with arRP in which the cause of the disease had not yet been identified with commonly used techniques.

    freshwater and untreated wastewater, as these systems showed differences in soil properties between seasons such as P content and electric conductivity. Potential functional profiles revealed that differences in land use systems also influence distinct functional pathways. Nitrogen fixation, nitrification, denitrification pathways and methane metabolism are potentially enhanced in wastewater irrigation systems, while dissimilatory nitrate reduction, anammox, lignin and chitin degradation are diminished. The junction of 16S rRNA data and associated functional profiles provided extensive understanding into the bacterial community responses to changing environmental conditions associated with differences in land use, management and seasonality in drylands. Irrigation with wastewater can be potentially harmful as higher abundance of the pathogens A. baumanni, A. soli, A. junii, A. haemolyticus, A. schindleri, B. thuringiensis/anthracis,cereus and N. flavorosea was recorded in these systems.

    Chung, Ana Paula; Lopes, André; Nobre, M Fernanda; Morais, Paula V


    Three red-pink pigmented strains, designated A1-12(T), A2-50A(T) and A2-91(T), were recovered from two different sites in a uranium mine. For all strains, the optimum growth temperature was 25°C, the optimum pH was 6.0-6.5 and the DNA G+C contents were between 60 and 63.4 mol%. The major respiratory quinone was menaquinone 7 (MK-7) and the fatty acid profiles contained iso- and anteiso-branched C15 fatty acids, summed feature 3 (16:1 ω6c and/or ω7c and/or 15:0 iso 2-OH), summed feature 4 (17:1 anteiso B and/or iso I) and the unsaturated fatty acid 16:1 ω5c as the major components. Phylogenetic analysis of the 16S rRNA gene sequences showed that these organisms represented three distinct branches within the family Flexibacteraceae most closely related to the members of the genus Hymenobacter. Strain A1-12(T) formed a distinct phylogenetic line along with H. rigui KCTC 12533(T) and they shared approximately 98.9% 16S rRNA gene sequence similarity. However, these two strains shared only 14.7% pairwise similarity in their genomic DNA. Strains A2-50A(T) and A2-91(T) formed two distinct lineages, related to the species H. soli KCTC 12607(T), sharing about 95.5% 16S rRNA gene sequence similarity between themselves, and 88.3 and 92.0% with other members of the genus Hymenobacter. Based on the phylogenetic analysis and physiological and biochemical characteristics, these isolates were considered to represent three novel species for which we propose the names Hymenobacter perfusus for strain A1-12(T) (=CIP 110166=LMG 26000), Hymenobacter flocculans for strain A2-50A(T) (=CIP 110139=LMG 25699) and Hymenobacter metalli for strain A2-91(T) (=CIP 110140=LMG 25700).

U 20. stoljeću oformio se, između ostalih, pristup da je zadatak prevoditelja prijevodom oponašati izvorno lirsko djelo, a uz to što prijevod treba preslikavati original, on također treba zadržati i njegovu poetsku vrijednost te u ciljnom jeziku funkcionirati kao samostalna poetska forma (bez glosa, komentara ili fusnota. Budući da je svaka pjesma priča za sebe, svaki je prevoditelj pri definiranju prioriteta (zvučnost? semantika? rima? ritam? prepušten samom sebi i konstantno se suočava s izborima (Jones (citat u Connolly 174 prevođenje poezije naziva “umjetnošću kompromisa”. W. S. Merwin opisuje svoj pristup prevođenju poezije na sljedeći način: “Znate, i dalje vjerujem da ne znam kako se prevodi i da to nitko ne zna. To je nemoguć, ali nužan proces, ne postoji savršen način da se on izvede i velik njegov dio mora se oblikovati u hodu za svaku pojedinačnu pjesmu.”

  13. NASA's Chandra Reveals Origin of Key Cosmic Explosions (United States)


    WASHINGTON -- New findings from NASA's Chandra X-ray Observatory have provided a major advance in understanding a type of supernova critical for studying the dark energy that astronomers think pervades the universe. The results show mergers of two dense stellar remnants are the likely cause of many of the supernovae that have been used to measure the accelerated expansion of the universe. These supernovae, called Type Ia, serve as cosmic mile markers to measure expansion of the universe because they can be seen at large distances, and they follow a reliable pattern of brightness. However, until now, scientists have been unsure what actually causes the explosions. "These are such critical objects in understanding the universe," said Marat Gilfanov of the Max Planck Institute for Astrophysics in Germany and lead author of the study that appears in the Feb. 18 edition of the journal Nature. "It was a major embarrassment that we did not know how they worked. Now we are beginning to understand what lights the fuse of these explosions." Most scientists agree a Type Ia supernova occurs when a white dwarf star -- a collapsed remnant of an elderly star -- exceeds its weight limit, becomes unstable and explodes. Scientists have identified two main possibilities for pushing the white dwarf over the edge: two white dwarfs merging or accretion, a process in which the white dwarf pulls material from a sun-like companion star until it exceeds its weight limit. "Our results suggest the supernovae in the galaxies we studied almost all come from two white dwarfs merging," said co-author Akos Bogdan, also of Max Planck. "This is probably not what many astronomers would expect." The difference between these two scenarios may have implications for how these supernovae can be used as "standard candles" -- objects of a known brightness -- to track vast cosmic distances. Because white dwarfs can come in a range of masses, the merger of two could result in explosions that vary somewhat in

    zahvat, koji se odnosi na zamenu celokupne instrumentacije je u toku, ali njegova realizacija u 1991. godini kasni zbog zastoja u isporuci opreme koja se izradjuje u Sovjetskom savezu. Izradu ove opreme finansira Medjunarodna agencija za atomsku energiju kroz ugovor sklopljen decembra 1988. godine sa moskovskom firmom Atomenergoexport. Prema tom ugovoru trebalo je da celokupna nova instrumentacija za reaktor RA bude isporucena Institutu u Vinci do kraja 1990. godine, ali je do septembra 1991. godine isporuceno svega 56% od predvidjene kolicine. Od tada je svaka isporuka obustavljena, a razlog je privremena zabrana na sve isporuke opreme za Jugoslaviju izrecena od strane ove organizacije Ujedinjenih nacija. U 1991. godini na reaktoru RA je demontirana postojeca instrumentacija u maksimalno mogucem obimu, kako bi se zadrzala neka osnovna merenja neophodna i u uslovima kada reaktor nije u pogonu. Pri kraju je izrada odredjenih konstrukcionih elemenata za novu instrumentaciju, koju je prihvatio da realizuje Institut u Vinci, kako bi se ubrzala realizacija ovog projekta. Ako sva predvijena oprema ne bude isporucena do kraja marta 1992. godine, nece moci da se otpocne sa probnim radom reaktora u prvoj polovini 1993. godine, kako je planirano. Na realizaciji projekta u 1991. godini ucestvovalo je efektivno 53 radnika, sto je dovoljan broj u uslovima remontnih i investicionih radova. Godisnji izvestaj o radu nuklearnog reaktora RA za 1992. godinu sastoji se od dva dela: prvi deo obuhvata pogon i odzavanje reaktora RA, a drugi poslove zastite od zracenja na reaktoru RA.

    Energy Technology Data Exchange (ETDEWEB)



    The Liquid Phase Methanol (LPMEOW) Demonstration Project at Kingsport Tennessee, is a $213.7 million cooperative agreement between the U.S. Department of Energy (DOE) and Air Products Liquid Phase Conversion Company, L.P. (the Partnership) to produce methanol from coal-derived synthesis gas (syngas). Air Products and Chemicals, Inc. (Air Products) and Eastman Chemical Company (Eastman) formed the Partnership to execute the Demonstration Project. The LPMEOW Process Demonstration Unit was built at a site located at the Eastman complex in Kingsport. During this quarter, initial planning and procurement work began on the seven project sites which have been accepted for participation in the off-site, methanol product-use test plan. Two of the projects have begun pre-testing of equipment and three other projects have commenced with equipment procurement, Methanol produced from carbon monoxide (CO)- rich syngas at the Alternative Fuels Development Unit (AFDU) in LaPorte, TX has been shipped to four of the project sites in anticipation of the start of testing during the first quarter of calendar year 1998. Catalyst activity, as defined by the ratio of the rate constant at any point in time to the rate constant for a freshly reduced catalyst (as determined in the laboratory autoclave), continued to decline more rapidly than expected. In response to concentrations of arsenic and sulfbr detected on catalyst samples from the LPMEOW Reactor, Eastman replaced both the arsine- and sulfiwremoval material in the Eastman guard bed which treats the primary syngas feed stream (&danced Gas) prior to its introduction into both the Eastman fixed-bed methanol plant and the LPMEOWM Demonstration Unit. After restarting the demonstration unit, the catalyst deactivation rate remained essentially unchanged.

Keywords included negatively-valenced words like "sad", "unworthy", or "tired" which are almost always accompanied by personal pronouns, such as "I", "I'm" or "my" and in Filipino, "ako" or "ko". For the content validation, only keywords with CVR equal to or more than 0.75 were included in the depression lexicon test-run version. The mean of all CVRs yielded a high overall CVI of 0.90. A total of 1498 main keywords, 8911 derivatives of main keywords, and 783,140 spelling variations, with a total of 793, 553 keywords now comprise the test-run version. The generation of the depression lexicon is relatively exhaustive. The breadth of keywords used in text analysis incorporates the characteristic expressions of depression and its related constructs by a particular culture and age group. A content-validated mobile health app, PiaP may help augment a more effective and early detection of depressive symptoms.

  20. Astronomijos ir meteorologijos jungtys Arato Reiškiniuose. The Connections Between Astronomy and Meteorology in Aratus’ Phaenomena

    Directory of Open Access Journals (Sweden)

    Naglis Kardelis


    Full Text Available The author of the article focuses on the connections between astronomy and meteorology in the Phaenome­na of Aratus of Soli (fl. 276 BC. Firstly, the attention is drawn to such connections that are apparent in the structure of the poem which has two structural parts, the astronomical and the meteorological. It is shown that the astronomical part does not end abruptly, but merges gradually into the meteorological one. Such effect is achieved by way of methodical downward transition from the North pole and the upper sky, via the lower sky, to the atmosphere and then to the very surface of earth. Therefore, Aratus first of all describes the celestial phenomena as such, simply as marvels of the sky, without any reference to their prognostic (that is, meteorological function. Then he speaks of them in relation to their prognostic function. After that the poet descends from the level of celestial phenomena to the level of earth’s atmosphere, that is, from astronomical to meteorological level, and focuses on meteorologi­cal phenomena proper, such as the rain, the storm, the wind, the snow, the rainbow, and so on, drawing attention to their prognostic function. Then the poet descends even lower, from the level of atmosphere to the level of earth’s surface, and describes various earthly phenomena, such as prognostically relevant physical and chemical properties of various common substances and strange behaviour of animals which also has significant prognostic value. In the process of the overall gradual descent from the North pole to the ground level, the poet, when it serves his artistic purpose, sometimes quickly and unexpectedly changes the scale from large to small (and vice versa, or alti­tude from high to low (and vice versa, or even speaks of various phenomena that simultaneously appear on different scale, large and small, and on different levels, astronomical and meteorological.Secondly, the author of the article analyses the connections

  1. Evaluation of the Delta-T SPN1 radiometer for the measurement of solar irradiance components (United States)

    Estelles, Victor; Serrano, David; Segura, Sara; Wood, John; Webb, Nick; Utrillas, Maria Pilar


    In this study we analyse the performance of an SPN1 radiometer built by Delta-T Devices Ltd. to retrieve global solar irradiance at ground and its components (diffuse, direct) in comparison with measurements from two Kipp&Zonen CMP21 radiometers and a Kipp&Zonen CHP1 pirheliometer, mounted on an active Solys-2 suntracker at the Burjassot site (Valencia, Spain) using data acquired every minute during years 2013 - 2015. The measurement site is close to sea level (60 m a.s.l.), near the Mediterranean coast (10 km) and within the metropolitan area of Valencia City (over 1.500.000 inhabitants). The SPN1 is an inexpensive and versatile instrument for the measurement of the three components of the solar radiation without any mobile part and without any need to azimuthally align the instrument to track the sun ( The three components of the solar radiation are estimated from a combination of measurements performed by 7 different miniature thermopiles. The SPN1 pyranometer measures the irradiance between 400 and 2700 nm, and the nominal uncertainty for the individual readings is about 8% ± 10 W/m2 (5% for the daily averages). The pyranometer Kipp&Zonen CMP21 model is a secondary standard for the measurement of broadband solar global irradiance in horizontal planes. Two ventilated CMP21 are used for the measurement of the global and diffuse irradiances. The expected total daily uncertainty of the radiometer is estimated to be 2%. The pirheliometer Kipp&Zonen CHP1 is designed for the measurement of the direct irradiance. The principles are similar to the CMP21 pyranometer. The results of the comparison show that the global irradiance from the SPN1 compares very well with the CMP21, with absolute RMSD and MBD differences below the combined uncertainties (15 W/m2 and -5.4 W/m2, respectively; relative RMSD of 3.1%). Both datasets are very well correlated, with a correlation coefficient higher than 0.997 and a slope and intercept very close to 1 and 0

Nel processo di apprendimento di conoscenze acquisite non solo attraverso l’ascolto delle parole dell’insegnante, ma anche attraverso esperienze scelte autonomamente e consapevolmente da soli e in gruppo, l’ambiente delle stazioni didattiche offre tutto il materiale di sviluppo cognitivo in maniera che sia liberamente fruibile dal discente per favorirne la socializzazione e l’autonomia (secondo il motto di Maria Montessori ‘Aiutami a fare da solo’. A lezione esse non solo offrono varietà, comunicazione e divertimento ma, e in ciò è il loro massimo pregio, differenziazione interna al gruppo degli studenti, che possono, senza alcuna pressione da parte dei compagni, lavorare al proprio ritmo e livello scegliendogli esercizi secondo le preferenze individuali lungo un percorso aperto a canali diversi di apprendimento e orientato ad un vivace interscambio con gli altri.Il nostro contributo fa riferimento a tre esempi di stazioni didattiche legate alle feste che più richiamano l’attenzione degli studenti stranieri sul nostro paese: il Natale e il Carnevale.

  5. Spatial and temporal variation in marine birds in the north Gulf of Alaska: The value of marine bird monitoring within Gulf Watch Alaska (United States)

    Kuletz, Kathy J.; Esler, Daniel N.


    Birds offer useful insights into marine ecosystems. Marine birds are responsive to spatial and temporal variation in the environment, that often originates with fluctuations in oceanographic and climatic drivers and permeates up through food webs to conspicuous top predators such as seabirds (Coyle and Pinchuk 2005, Speckman et al. 2005, Gonzales-Solis et al. 2009, Cushing et al., this report). In that way, marine birds are excellent assimilators, samplers, and indicators of the status of marine environments (Montevecchi 1993, Piatt et al. 2007b, Zador et al. 2013). Marine bird responses to dynamic marine ecosystems can be detected in a variety of metrics, including abundance, distribution, and productivity. For example, in the northern Gulf of Alaska (GOA), decadal-scale variation in oceanographic conditions has been associated with dramatic shifts in prey composition and abundance (Anderson and Piatt 1999). In turn, these shifts were more closely correlated with changes in abundance of fish-eating birds of Prince William Sound (PWS), such as pigeon guillemots (Golet et al. 2002) and marbled and Kittlitz’s murrelets (Kuletz et al. 2011a, 2011b), than in the abundance of species that primarily consume plankton or benthic prey (Agler et al. 1999, Cushing et al., this report). Birds also are responsive to anthropogenic influences in marine environments, including commercial fishing, contamination, introduction of non-native species, coastal development, offshore resource extraction, and vessel traffic. A major anthropogenic perturbation in the northern GOA was the 1989 Exxon Valdez oil spill, in which marine birds suffered high immediate mortality (Piatt and Ford 1996). Additionally, several species showed long-term evidence of declines in the oiled areas of PWS (Lance et al. 2001), as well as impacts to reproductive success years later (Golet et al. 2002). However, the degree of direct impact and vulnerability to chronic injury, which was related to exposure to

    The leaves of Pereskia bleo (pokok jarum tujuh), are being used in Malaysian traditional medicine for the prevention and treatment of breast cancer. In order to validate the use of this plant in breast cancer treatment we have prepared crude extracts of the leaves and assessed them for activity against several breast cancer cell lines such as the MCF-7, MDA-MB231 and against non-tumour 3T3 cells. The crude extracts were also subjected to toxicity test using brine shrimp lethality assay. Dried and milled Pereskia bleo leaves were extracted successively with petroleum ether, chloroform, methanol and distilled water. Extracts of the organic solvent were filtered and the supernatant were concentrated using the rotary evaporator. The aqueous extract was lyophilized. The extracts were screened for the presence of alkaloids, terpenoids, flavanoids and saponins. Activity against Artemia salina was determined using a 96-well microplate method (Solis et al., 1993). Inhibition of growth of cultured cancer cell lines were measured using a standard MTT assay. Cytotoxic drugs, tamoxifen, was used as a positive control against the brine shrimps and cell lines, respectively. All the non-polar extracts of the leaves were found to exhibit significant cytotoxic activities against both the ER positive (MCF7) and ER negative (MDA-MB231) breast cancer cell-lines but. All the extracts were found to be not cytotoxic against the non-tumour (3T3) cells. The non-polar extracts were found to be 2 to 3 times more cytotoxic than the more polar methanol extracts against the ER positive, MCF-7 cells. The strongest cytotoxic activity was observed with petroleum extract with IC50 values of 6.5 μg/ml and 11.5 μg/ml towards MCF-7 and MDA-MB cell lines, respectively. The cytotoxic activities of the petroleum ether and chloroform extracts against the ER negative, MDA-MB231 cell-line are about the same (IC50 19.3 to 26.3 μg/ml ). The cytotoxic activities of the anticancer drug, tamoxifen, against the

    present mainly in HSP (heat-sensitive protein) while cellullar Ag from Ag ion and AgNPs (Ag/PVP, Ag/citrate) treatments were found mostly in cellular debris. No statistical difference in partitioning of metals among different subcelluar pools was found between the metal forms. Zn from ZnO contaminated solis was found largely in carbonate fraction (41%), while Zn from Zn ion treatment was found in Fe-Mn Oxide (29%). Association of Zn to mobile fractions (ZnO; 65%, Zn ion; 35%) suggest that Zn from ZnO contaminated soil would be more bioavailable than that from Zn ion treatment. However, the BAFs for Zn in the animals did not follow this prediction. Majority of Ag from AgNPs or Ag ion contaminated soil was bound mainly to biologically inert fractions mainly in organic matter, surphide fractions, and residual fractions. Consistent with these findings, the BAFs of Ag in the worms exposed to Ag contaminated soils were generally lower than those for Zn treatments.

  10. Zasady żywienia dzieci w drugim i trzecim roku życia

    Full Text Available W artykule przedstawiono aktualny stan wiedzy na temat zasad żywienia dzieci w 2. i 3. roku życia. W okresie poniemowlęcym zapotrzebowanie energetyczne dziecka zmniejsza się do ok. 90 kcal/kg mc./dobę. Zmianie ulega również tempo jego wzrostu. Połowa energii wydatkowana jest na potrzeby aktywności fizycznej, więc potrzeby żywieniowe dziecka są od nich uzależnione. Rozkład podaży energii pozabiałkowej powinien wynosić 60-65% z węglowodanów i 35-40% z tłuszczu. Należy zadbać o stopniowe wzbogacanie diety o kwasy tłuszczowe (NNKT, zawarte w olejach roślinnych, tłustych rybach morskich, orzechach oraz zielonych warzywach. Do 2. roku życia zalecana jest dieta bogata w tłuszcze, głównie pochodzące z masła, następnie należy stopniowo ograniczać tłuszcze zwierzęce, aby uniknąć otyłości. Dziecku nie należy podawać tłustych mięs oraz surowych jaj, gdyż zawierają one awidynę. Do 3. roku życia korzystniejsze jest podawanie mieszanek mlecznych typu „junior” niż pełnego mleka krowiego. Rekomendowane produkty zbożowe zawierające węglowodany to przede wszystkim pieczywo razowe oraz grube kasze. Zapotrzebowanie na płyny u małego dziecka wynosi ok. 950 ml/dobę. Najlepsze do picia są woda, niesłodzone herbatki ziołowe i naturalne soki owocowe. Ważna jest też forma, czyli w jaki sposób przyjmowane są pokarmy. Należy kształtować w dziecku dobre nawyki i przyzwyczajenia związane z jedzeniem, kierując się zasadą 4U: urozmaicenie, umiar, unikanie i uregulowanie. Obecnie można zauważyć poprawę w stanie odżywienia polskich dzieci, choć nadal sposób ich żywienia bywa niezadowalający. Do najczęstszych błędów zalicza się nadmierne używanie soli, mało urozmaiconą dietę, brak czasu i zniecierpliwienie w czasie posiłków, nerwową atmosferę w czasie posiłków oraz nadmierne rozdrabnianie produktów.

  12. microRNA regulatory mechanism by which PLLA aligned nanofibers influence PC12 cell differentiation (United States)

    Yu, Yadong; Lü, Xiaoying; Ding, Fei


    Objective. Aligned nanofibers (AFs) are regarded as promising biomaterials in nerve tissue engineering. However, a full understanding of the biocompatibility of AFs at the molecular level is still challenging. Therefore, the present study focused on identifying the microRNA (miRNA)-mediated regulatory mechanism by which poly-L-lactic acid (PLLA) AFs influence PC12 cell differentiation. Approach. Firstly, the effects of PLLA random nanofibers (RFs)/AFs and PLLA films (control) on the biological responses of PC12 cells that are associated with neuronal differentiation were examined. Then, SOLiD sequencing and cDNA microarray were employed to profile the expressions of miRNAs and mRNAs. The target genes of the misregulated miRNAs were predicted and compared with the mRNA profile data. Functions of the matched target genes (the intersection between the predicted target genes and the experimentally-determined, misregulated genes) were analyzed. Main results. The results revealed that neurites spread in various directions in control and RF groups. In the AF group, most neurites extended in parallel with each other. The glucose consumption and lactic acid production in the RF and AF groups were higher than those in the control group. Compared with the control group, 42 and 94 miRNAs were significantly dysregulated in the RF and AF groups, respectively. By comparing the predicted target genes with the mRNA profile data, five and 87 matched target genes were found in the RF and AF groups, respectively. Three of the matched target genes in the AF group were found to be associated with neuronal differentiation, whereas none had this association in the RF group. The PLLA AFs induced the dysregulation of miRNAs that regulate many biological functions, including axonal guidance, lipid metabolism and long-term potentiation. In particular, two miRNA-matched target gene-biological function modules associated with neuronal differentiation were identified as follows: (1) miR-23b, mi

The aim of this study was to identify and quantify the organisms groups of the soil mesofauna and determine Pb and Zn contents in plants in the mining and metallurgy plant in Adrianópolis (PR,to originate biological indicators of the quality of these solis. At the selected locations the following contamination forms were analized: site 1 - reference (native wood; site 2 - residue incorporated in the profile; sites 3 and 6 - close to the chimneys of the plant, with potential import of particulate matter; site 5 - great waste volume covering the soil. Berlese funnels were utilized to collect samples from the 0 to 5 cm layer (20 funnels x 5 sites x 1 layer x 4 times = 400 samples.

    Mitja Skubic


    Full Text Available L'autore esamina la lingua dello scritto e t iestino Boris Pahor, urio de li eminenti creatori letterari in sloveno del secondo dopoguerra. Gli anni di scuola ed una  parte della giovinezza di Boris Pahor, nato nel 1913, appartengono ad un periodo nel quale lo sloveno a Trieste, e nelle province di Trieste       e di Gorizia, non godeva di uno  status pubblico ufficiale, salvo in chiesa. L influsso linguistico dell'italiano, normale in un territorio etnicamente e linguisticamente misto, spinto in una situazione anormale, creatasi nel primo  dopoguerra, non sorprende. Lo scrittore fu in  stretto contratto con l'italiano e il legame linguistico (e certo anche culturale è 'di doppia natura: esisstono, da una parte, influenze della parlata locale triestina -veneta, con qualche venatura tergestina, vale a dire friulana; dell'altra, lo scrittore ebbe a subire numerose influenze dell'italiano letterario. Non è facile scindere queste due fonti dei romanismi linguistici, che chiamiamo genericamente italianismi; il termine è fallace, perchè è fallace la grafia la quale rare volte palesa l'origine veneta: ščaveta, škojera, mandrijer, čožotska bragoca. L'interesse di questo contributo si concentra su prestiti, per lo più adattati al sistema fono-morfologico che vige per lo sloveno, e, soprattutto7 su calchi, quelli semantici e quelli sintattici. Una quantità non trascurabile di calchi ci convince della loro provenienza popolare, del fatto, cioe, che bisogna cer­ carne l'origine nel contatto linguistico diretto delle due etnie. Il materiale raccolto contraddice, dunaue. l'asserzione alquanto apodittica della provenienza popolare, immediata, dei soli presti­ ti e della provenienz letteraria, dotta, dei calchi. I calchi semantici sono parecchi: si tratta sempre dell'uso di un termine sloveno che in sloveno letterario e nei dialetti centrali esiste, ma che in Pahor viene usato con un significate sconosciuto allo sloveno centrale

    Preciozzi, F; Pell, E; Muzio, R; Ledesma, J.J; Guerequiz, R


    The western cratonic domains in Uruguay are divided into three major units: Piedra Alta Terrane, Valentines Block and Pavas Terrane. Piedra Alta Terrane lacks of evidence of Neo proterozoic oro geneses (deformation, metamorphism or magmatism). Sarandi del Yi - Arroyo Solis Grande shear zone, separates it from Valentines Block. Valentines Block is separated from Pavas Terrane by Cueva del Tigre shear zone. Magmatic rocks with different ages, compositions and emplacements occur all over the Piedra Alta Terrane distributed in three metamorphic belts (Arroyo Grande, San Jose and Montevideo) as well as in the Central Gneissic-Migmatitic Complex. Samples from the gneissic-migmatitic complex, late tectonic granitoids and basic rocks associated to the metamorphic belts were analyzed using Rb/Sr, U/Pb, K/Ar and Sm/Nd methodologies. The age ranges obtained for granitoids and gneissicmigmatitic samples using Rb/Sr whole rock (WR) systematics are 1.7 to 2.5 Ga, showing two intervals: 1.9 to 2.05 Ga (intrusion of late granites) and 2.1 to 2.2 Ga (deformation and metamorphism). K/Ar cooling ages present several ranges: 1.3 to 1.35 Ga (probable local heating of the crust), 1.7 to 1.8 Ga (microgabbro magmatism, data confirmed by the Ar/Ar method) and ages between 2.0 to 2.2 Ga. Rb/Sr (WR) data yielded an isochronic age of 2094 ± 28.3 Ma, Ro = 0.70174 ± 0.00009, MSWD 19.74, interpreted as the time of the metamorphic event recognized for all the Piedra Alta Terrane. TDM Sm/Nd model ages presented a range from 2065 Ma to 2450 Ma. U/Pb systematics yield ages in migmatitic and gneissic rocks from 2.16 Ga to 2.21 Ga, showing metamorphism and deformation phenomena. While the ages of granitoids associated to the San Jose Belt are between 2.06 Ga and 2.08 Ga (Isla Mala) to 2.1 Ga (Granito de Cufre). None of them show metamorphic phenomena. Valentines Block (Preciozzi et al., 1979) comprises granulitic gneisses, granitoids and mafic rocks of different compositions. The geologic complexity

    снованных на тех же технологиях, и они одинаково важны как для управления рисками в военных операциях в киберпространстве, так и в области обороны, разведки и международного гуманитарного права. / Procena ranjivosti i testiranje otpornosti na upade u sistem su ključne aktivnosti upravljanja rizikom u informacionoj bezbednosti, sajber odbrani i obaveštajnom radu vojnih organizacija. Ove aktivnosti su značajne u kontekstu izvođenja vojnih operacija, ali i u kontekstu Međunarodnog humanitarnog prava (IHL i sprovođenja zakona. Primena informacionih tehnologija u vojnom i civilnom okruženju povećava kompleksnost u oblasti upravljanja rizikom. Pored informacione bezbednosti, vojne organizacije imaju zadatak da preduzmu neophodne aktivnosti u oblasti sajber operacija, za svrhe odbrane i napada. Oni zavise od znanja i veština zasnovanih na tehnologiji i implementiraju ih specifične organizacije u okviru vojnih sistema. Procena ranjivosti za cilj ima otkrivanje prirode ranjivosti, bez razmatranja kako se one mogu koristiti za napad, dok testiranje otpornosti na upade u sistem koristi eksploite za upade u sisteme i tako procenjuje vrstu i stepen rizika koji ove ranjivosti predstavljaju za sistem. Međutim, čak i ako predstavljaju dve različite aktivnosti, sa različitim krajnjim ciljevima, oni su komplementarni i međuzavisni. Pošto je njihova zajednička odlika razvoj znanja i veština zasnovanih na istim tehnologijama, oni su od podjednake važnosti za upravljanje rizikom, vojne operacije u sajber prostoru i njihovu upotrebu za odbrambene i obaveštajne aktivnosti, kao i međunarodno humanitarno pravo.

    zbornika jest i tema vlasništva pojedinog primjerka stare knjige. Upravo tu temu obradio je D. Shaw pod naslovom Tko je bio vlasnik ove knjige? Proučavanje porijekla knjiga u europskim razmjerima. Autor naglašava važnost katalogizacije na temelju pojedinog primjerka jer se jedino tako u kataložnom zapisu mogu zabilježiti sve karakteristike i posebnosti pojedinog primjerka građe. Upravo takav postupak opisa potaknuo je razvoj područja kojim se bavi autor u svome radu - proučavanja porijekla knjige. Važnost proučavanja prethodnih vlasnika jasno se vidi u mogućnosti okupljanja raspršenih knjižnica i privatnih zbirki koje svoju „pripadnost“ određenoj zbirci ponekad mogu dokazati jedino obilježjima vlasnika ili knjižnice kojoj su nekoć pripadali. Osim vlastoručnih potpisa vlasnika i pečata knjižnice, dokazi o prijašnjim vlasnicima mogu se istražiti i uz pomoć signatura, ex librisa, pečata na uvezima itd. Veliku pomoć u toj vrsti istraživanja pruža i Konzorcij europskih knjižnica (CERL koji nudi mrežnu bazu podataka o porijeklu knjiga. Posljednji rad u ovoj cjelini izradila je doktorska studentica M. Tomić pod naslovom Podaci o povijesti primjerka u hrvatskim katalozima stare i rijetke građe. Autorica je prikupila dostupne (tiskane kataloge te je kroz te kataloge i kataložne zapise starih i rijetkih knjiga u online katalozima istražila koliko se bilježe podaci o porijeklu primjerka. U radu su prikazani rezultati spomenutog istraživanja s posebnim osvrtom na podatke o povijesti primjerka ukoliko su (i ako su uopće uključeni u tiskane kataloge stare i rijetke građe u hrvatskim knjižnicama te u online katalozima hrvatskih knjižnica. Dodana vrijednost ovoga rada jest i bibliografija kataloga inkunabula, kataloga knjiga i rukopisa koji se nalaze u muzejskim knjižnicama i crkvenim ustanovama te kataloga izložbi starih i rijetkih knjiga. Neki od izvora koji su istraženi nisu ranije uključivani u postojeće bibliografije stare gra

    suficiente para proceder a la reseccion quirurgica, quizas sea esta la contribucion mas importante del metodo hasta la fecha. En cambio, los resultados con tumores subtentoriales fueron menos satisfactorios, pues se fracaso en 23 de 39 casos, es decir en el 59 por ciento. En el grupo de enfermedades benignas, el arsenico permitid localizar 7 de 8 hematomas subdurales, mientras que la exploracion mediante cobre no dio ningun resultado positivo en tres casos. En cuatro casos sobre cinco el empleo del arsenico permitio localizar coagulos intracerebrales diagnosticados. La totalidad de los 10 abscesos estudiados fue diagnosticada mediante el arsenico, y 3 de cada 4 mediante el cobre. En los tres pacientes que sufrian de leucoencefalopatia, la exploracion mediante arsenico indico las zonas principales de desmielinizacion. De 10 pacientes que hablan sido sometidos a un total de 16 exploraciones, y a los que posteriormente se efectuo una craneotomia exploratoria con resultado negative, no hubo mas que dos en los cuales la exploracion (mediante arsenico y cobre respectivamente) habia permitido diagnosticar una anormalidad localizada y bien definida.
