  4. RepA and RepB exert plasmid incompatibility repressing the transcription of the repABC operon.

    Science.gov (United States)

    Pérez-Oseguera, Angeles; Cevallos, Miguel A

    2013-11-01

    Rhizobium etli CFN42 has a multipartite genome composed of one chromosome and six large plasmids with low copy numbers, all belonging to the repABC plasmid family. All elements essential for replication and segregation of these plasmids are encoded within the repABC operon. RepA and RepB direct plasmid segregation and are involved in the transcriptional regulation of the operon, and RepC is the initiator protein of the plasmid. Here we show that in addition to RepA (repressor) and RepB (corepressor), full transcriptional repression of the operon located in the symbiotic plasmid (pRetCFN42d) of this strain requires parS, the centromere-like sequence, and the operator sequence. However, the co-expression of RepA and RepB is sufficient to induce the displacement of the parental plasmid. RepA is a Walker-type ATPase that self associates in vivo and in vitro and binds specifically to the operator region in its RepA-ADP form. In contrast, RepA-ATP is capable of binding to non-specific DNA. RepA and RepB form high molecular weight DNA-protein complexes in the presence of ATP and ADP. RepA carrying ATP-pocket motif mutations induce full repression of the repABC operon without the participation of RepB and parS. These mutants specifically bind the operator sequence in their ATP or ADP bound forms. In addition, their expression in trans exerts plasmid incompatibility against the parental plasmid. RepA and RepB expressed in trans induce plasmid incompatibility because of their ability to repress the repABC operon and not only by their capacity to distort the plasmid segregation process.

  5. Study of ethylene/2-butene cross-metathesis over W-H/Al2O 3 for propylene production: Effect of the temperature and reactant ratios on the productivity and deactivation

    KAUST Repository

    Mazoyer, Etienne

    2013-05-01

    A highly active and selective catalyst based on supported tungsten hydride for the cross-metathesis between ethylene and 2-butenes yielding propylene has been investigated at low pressure with various temperatures and feed ratios. At low temperature (120 °C), the catalyst deactivates notably with time on stream. This phenomenon was extensively examined by DRIFTS, TGA, DSC, and solid-state NMR techniques. It was found that a large amount of carbonaceous species were formed due to a side-reaction such as olefin polymerization which took place simultaneously with the metathesis reaction. However, at 150 °C, the catalyst was stable with time and thereby gave a high productivity in propylene. Importantly, the slight increase in temperature clearly disfavored the side reaction. The ratio of ethylene to trans-2-butene was also studied, and surprisingly, the W-H/Al2O3 catalyst is stable and highly selective to propylene even at substoichiometric ethylene ratios. © 2013 Elsevier Inc.

    The notions of int-soft semigroups and int-soft left (resp., right) ideals in semigroups are studied in the paper by Song et al. (2014). In this paper, further properties and characterizations of int-soft left (right) ideals are studied, and the notion of int-soft (generalized) bi-ideals is introduced. Relations between int-soft generalized bi-ideals and int-soft semigroups are discussed, and characterizations of (int-soft) generalized bi-ideals and int-soft bi-ideals are considered. Given a soft set (α;S) over U, int-soft (generalized) bi-ideals generated by (α;S) are established. PMID:25710051

  15. Activation of int-1 and int-2 loci in GRf mammary tumors.

    1986-10-30

    The Mtv-2 locus is known to be associated with a high mammary tumor incidence (97%) and early development of mammary tumors (3-13 months) in GR mice. However, it was not previously known whether the provirus which resides at the Mtv-2 locus is tumorigenic in and of itself or whether reintegration of proviruses generated from Mtv-2 is required for tumorigenesis. Foster-nursing GR mice on C57/BL mice eliminates the milk-borne source of GR virus, and allows the study of Mtv-2 derived proviruses alone. Using this approach, we have tested predictions which follow from the "positional" versus "reintegrational" models of tumorigenesis. Specifically, we have examined tumors from primary foster-nursed (GRf) mice to determine if MMTV proviruses derived from Mtv-2 were scattered randomly throughout the genome or were clustered in the vicinity of the int-1 and int-2 loci, which are thought to be associated with mammary tumorigenesis. It was found that the majority of spontaneous GRf mammary tumors that were tested have MMTV proviral integrations in either or both of the int-1 and int-2 loci and have transcription of either or both of the int loci. Tumors induced by Mtv-2, therefore, appear to have arisen via a mechanism similar to the activation of the int loci by exogenous (milk-borne) MMTV proviruses.

  16. The replication origin of a repABC plasmid

    2011-06-01

    Full Text Available Abstract Background repABC operons are present on large, low copy-number plasmids and on some secondary chromosomes in at least 19 α-proteobacterial genera, and are responsible for the replication and segregation properties of these replicons. These operons consist, with some variations, of three genes: repA, repB, and repC. RepA and RepB are involved in plasmid partitioning and in the negative regulation of their own transcription, and RepC is the limiting factor for replication. An antisense RNA encoded between the repB-repC genes modulates repC expression. Results To identify the minimal region of the Rhizobium etli p42d plasmid that is capable of autonomous replication, we amplified different regions of the repABC operon using PCR and cloned the regions into a suicide vector. The resulting vectors were then introduced into R. etli strains that did or did not contain p42d. The minimal replicon consisted of a repC open reading frame under the control of a constitutive promoter with a Shine-Dalgarno sequence that we designed. A sequence analysis of repC revealed the presence of a large A+T-rich region but no iterons or DnaA boxes. Silent mutations that modified the A+T content of this region eliminated the replication capability of the plasmid. The minimal replicon could not be introduced into R. etli strain containing p42d, but similar constructs that carried repC from Sinorhizobium meliloti pSymA or the linear chromosome of Agrobacterium tumefaciens replicated in the presence or absence of p42d, indicating that RepC is an incompatibility factor. A hybrid gene construct expressing a RepC protein with the first 362 amino acid residues from p42d RepC and the last 39 amino acid residues of RepC from SymA was able to replicate in the presence of p42d. Conclusions RepC is the only element encoded in the repABC operon of the R. etli p42d plasmid that is necessary and sufficient for plasmid replication and is probably the initiator protein. The ori

    The intricate complexity at the molecular and cellular levels of the processes leading to the development of amyloid proteinopathies is somehow counterbalanced by their common, universal structural basis. The later has fueled the quest for suitable model systems to study protein amyloidosis under quasi-physiological conditions in vitro and in simpler organisms in vivo. Yeast prions have provided several of such model systems, yielding invaluable insights on amyloid structure, dynamics and transmission. However, yeast prions, unlike mammalian PrP, do not elicit any proteinopathy. We have recently reported that engineering RepA-WH1, a bacterial DNA-toggled protein conformational switch (dWH1→mWH1) sharing some analogies with nucleic acid-promoted PrPC→PrPSc replication, enables control on protein amyloidogenesis in vitro. Furthermore, RepA-WH1 gives way to a non-infectious, vertically-transmissible (from mother to daughter cells) amyloid proteinopathy in Escherichia coli. RepA-WH1 amyloid aggregates efficiently promote aging in bacteria, which exhibit a drastic lengthening in generation time, a limited number of division cycles and reduced fitness. The RepA-WH1 prionoid opens a direct means to untangle the general pathway(s) for protein amyloidosis in a host with reduced genome and proteome. PMID:21293179

    The Geminiviruses genome is a small, single strand DNA that replicates in the plant cell nucleus. Analogous to animal DNA viruses, Geminiviruses depend on the host replication machinery to amplify their genomes and only supply the factors required to initiate their replication. Consequently, Geminiviruses remove the cell-cycle arrest and induce the host replication machinery using an endocycle process. They encode proteins, such as the conserved replication-associated proteins (Rep) that interact with retinoblastoma-like proteins in plants and alter the cell division cycle in yeasts. Therefore, the aim of this work is to analyze the impact of Pepper Golden Mosaic Virus (PepGMV) Rep protein in mammalian cells. Results indicate that the pTracer-SV40:Rep construction obtained in this work can be used to analyze the Rep protein effect in mammalian cells in order to compare the cell cycle regulation mechanisms in plants and animals.

    Since 2006, the European Near Earth Asteroids Research (EURONEAR) project has been contributing to the research of near-Earth asteroids (NEAs) within a European network. One of the main aims is the amelioration of the orbits of NEAs, and starting in 2014 February we focus on the recovery of one-opposition NEAs using the Isaac Newton Telescope (INT) in La Palma in override mode. Part of this NEA recovery project, since 2014 June EURONEAR serendipitously started to discover and secure the first NEAs from La Palma and using the INT, thanks to the teamwork including amateurs and students who promptly reduce the data, report discoveries and secure new objects recovered with the INT and few other telescopes from the EURONEAR network. Five NEAs were discovered with the INT, including 2014 LU14, 2014 NL52 (one very fast rotator), 2014 OL339 (the fourth known Earth quasi-satellite), 2014 SG143 (a quite large NEA), and 2014 VP. Another very fast moving NEA was discovered but was unfortunately lost due to lack of follow-up time. Additionally, another 14 NEA candidates were identified based on two models, all being rapidly followed-up using the INT and another 11 telescopes within the EURONEAR network. They include one object discovered by Pan-STARRS, two Mars crossers, two Hungarias, one Jupiter trojan, and other few inner main belt asteroids (MBAs). Using the INT and Sierra Nevada 1.5 m for photometry, then the Gran Telescopio de Canarias for spectroscopy, we derived the very rapid rotation of 2014 NL52, then its albedo, magnitude, size, and its spectral class. Based on the total sky coverage in dark conditions, we evaluate the actual survey discovery rate using 2-m class telescopes. One NEA is possible to be discovered randomly within minimum 2.8 deg2 and maximum 5.5 deg2. These findings update our past statistics, being based on double sky coverage and taking into account the recent increase in discovery.

    Model builders often need to find the most general Lagrangian which can be constructed from a given list of fields. These fields are actually representations of the Lorentz and gauge groups (and maybe of some discrete symmetry group as well). I will describe a simple program (Sym2Int) which helps to automate this task by listing all possible interactions between Lorentz/gauge group representations.

  3. Specific functions of the Rep and Rep׳ proteins of porcine circovirus during copy-release and rolling-circle DNA replication.

    Cheung, Andrew K

    2015-07-01

    The roles of two porcine circovirus replication initiator proteins, Rep and Rep׳, in generating copy-release and rolling-circle DNA replication intermediates were determined. Rep uses the supercoiled closed-circular genome (ccc) to initiate leading-strand synthesis (identical to copy-release replication) and generates the single-stranded circular (ssc) genome from the displaced DNA strand. In the process, a minus-genome primer (MGP) necessary for complementary-strand synthesis, from ssc to ccc, is synthesized. Rep׳ cleaves the growing nascent-strand to regenerate the parent ccc molecule. In the process, a Rep׳-DNA hybrid containing the right palindromic sequence (at the origin of DNA replication) is generated. Analysis of the virus particle showed that it is composed of four components: ssc, MGP, capsid protein and a novel Rep-related protein (designated Protein-3).

    Full Text Available Analyzing 167 non-processed seed samples of wheat, it was found that 145 samples (86.8 % were contaminated with Tilletia species, while 22 (13.2 % samples were not contaminated. By using rep-PCR fingerprinting technique, it was found that DNA isolates of T. tritici originated from Serbian wheat samples had 80 % similarity with positive control for T. tritici. One isolate shared similarity of 60% with T. tritici, T. controversa and T. laevis. It was supposed that this isolate belongs to T. bromi. Isolate of T. laevis shared a similarity of 70 % with isolates of T. tritici and T. controversa, while T. walkeri was more than 10 % similar with T. tritici, T. controversa and T. laevis. Although T. controversa and T. tritici had high percent of genetic similarity, they were clustered separately. Our results suggest that rep-PCR fingerprinting could be a useful tool for monitoring presence of morphologically similar Tilletia species in wheat production areas.

  9. Novel Mutant AAV2 Rep Proteins Support AAV2 Replication without Blocking HSV-1 Helpervirus Replication

    As their names imply, parvoviruses of the genus Dependovirus rely for their efficient replication on the concurrent presence of a helpervirus, such as herpesvirus, adenovirus, or papilloma virus. Adeno-associated virus 2 (AAV2) is such an example, which in turn can efficiently inhibit the replication of each helpervirus by distinct mechanisms. In a previous study we have shown that expression of the AAV2 rep gene is not compatible with efficient replication of herpes simplex virus 1 (HSV-1). In particular, the combined DNA-binding and ATPase/helicase activities of the Rep68/78 proteins have been shown to exert opposite effects on the replication of AAV2 and HSV-1. While essential for AAV2 DNA replication these protein activities account for the Rep-mediated inhibition of HSV-1 replication. Here, we describe a novel Rep mutant (Rep-D371Y), which displayed an unexpected phenotype. Rep-D371Y did not block HSV-1 replication, but still supported efficient AAV2 replication, at least when a double-stranded AAV2 genome template was used. We also found that the capacity of Rep-D371Y to induce apoptosis and a Rep-specific DNA damage response was significantly reduced compared to wild-type Rep. These findings suggest that AAV2 Rep-helicase subdomains exert diverging activities, which contribute to distinct steps of the AAV2 life cycle. More important, the novel AAV2 mutant Rep-D371Y may allow deciphering yet unsolved activities of the AAV2 Rep proteins such as DNA second-strand synthesis, genomic integration or packaging, which all involve the Rep-helicase activity.

  10. The INT6 cancer gene and MEK signaling pathways converge during zebrafish development.

    Directory of Open Access Journals (Sweden)

    Michal Grzmil

    Full Text Available BACKGROUND: Int-6 (integration site 6 was identified as an oncogene in a screen of tumorigenic mouse mammary tumor virus (MMTV insertions. INT6 expression is altered in human cancers, but the precise role of disrupted INT6 in tumorigenesis remains unclear, and an animal model to study Int-6 physiological function has been lacking. PRINCIPAL FINDINGS: Here, we create an in vivo model of Int6 function in zebrafish, and through genetic and chemical-genetic approaches implicate Int6 as a tissue-specific modulator of MEK-ERK signaling. We find that Int6 is required for normal expression of MEK1 protein in human cells, and for Erk signaling in zebrafish embryos. Loss of either Int6 or Mek signaling causes defects in craniofacial development, and Int6 and Erk-signaling have overlapping domains of tissue expression. SIGNIFICANCE: Our results provide new insight into the physiological role of vertebrate Int6, and have implications for the treatment of human tumors displaying altered INT6 expression.

    2017-05-01

    Stressed on crop can be monitored using different indices. Red Edge position is good estimator for stress monitoring. The red edge position (REP) is strongly correlated with foliar chlorophyll content. Strong chlorophyll absorption causes the abrupt change in the 680-800 nm region of reflectance spectra of green vegetation. The red edge consist the point of maximum slope between red and near-infrared wavelengths. REP can be used to recognize green zone of the observation area. The REP is present in spectra for vegetation recorded by remote sensing methods. REP is clearer and significant in hyper spectral data as hyper spectral consist of more and continuous bands data. In this paper experiments were carried out for mulberry crop using USGS EO-1 Hyperion data. Atmospheric corrected data is used for classification. Classification is carried out on small cluster of 14 field samples. Ground truth is verified and classified by comparing with Hyperion data. REP is different for different stressed condition of crops and shows healthy and diseased crop condition. Nutritional stresses, diseases, drought of plants are detected using REP. Stressed and healthy field of mulberry are estimated by calculating REP using maximum first derivative, linear interpolation, linear extrapolation method. Finally REP is compared using above methods. It is noticeable difference of REP for healthy and stressed crop. The research indicates that overall accuracy using maximum first derivative was 92.85 % and it was more compared to other methods. Linear extrapolation gives less accuracy compared to linear interpolation method.

  18. Mycoplasma pneumoniae large DNA repetitive elements RepMP1 show type specific organization among strains.

    Directory of Open Access Journals (Sweden)

    Oxana Musatovova

    Full Text Available Mycoplasma pneumoniae is the smallest self-replicating bacterium with a streamlined genome of 0.81 Mb. Complete genome analysis revealed the presence of multiple copies of four large repetitive elements (designated RepMP1, RepMP2/3, RepMP4 and RepMP5 that are implicated in creating sequence variations among individual strains. Recently, we described RepMP1-associated sequence variations between reference strain M129 and clinical isolate S1 that involved three RepMP1-genes (i.e. mpn130, mpn137 and mpn138. Using PCR and sequencing we analyze 28 additional M. pneumoniae strains and demonstrate the existence of S1-like sequence variants in nine strains and M129-like variants in the remaining nineteen strains. We propose a series of recombination steps that facilitates transition from M129- to S1-like sequence variants. Next we examined the remaining RepMP1-genes and observed no other rearrangements related to the repeat element. The only other detected difference was varying numbers of the 21-nucleotide tandem repeats within mpn127, mpn137, mpn501 and mpn524. Furthermore, typing of strains through analysis of large RepMPs localized within the adhesin P1 operon revealed that sequence divergence involving RepMP1-genes mpn130, mpn137 and mpn138 is strictly type-specific. Once more our analysis confirmed existence of two highly conserved groups of M. pneumoniae strains.

    A MOSFET based high voltage pulser is utilized to excite a microdischarge (MD), or microdischarge array (MDA) with pulsed voltages of up to 1 kV, with risetime and FWHM on the order of 10 ns and 30 ns, respectively. Additionally, the pulser is capable of pulsing at rep-rates in excess of 35 MHz. However, for these experiments the rep-rate was set on the order of 1 MHz, so as to limit excess energy deposition into the background gas and optimize the energy efficiency of VUV generation. Using VUV capable spectral diagnostics, the VUV emission of the MDs for various pressures (50-800 + Torr) and gases, focused on argon, argon-hydrogen mixtures, and neon-hydrogen mixtures (all of which provide strong emission at λ VUV emission is characterized and compared to results from transient fluid modeling of the MDA. For instance, the MDA turn-on time is recorded to be about 15 ns, which matches the full plasma development time in the model, and the MDA self- capacitance largely determines the turn-off behavior. This research was supported by an AFOSR grant on the Physics of Distributed Plasma Discharges and fellowships from the National Physical Sciences Consortium, supported by Sandia National Laboratories.

  20. Formation and properties of In-Te pairs in Si

    Energy Technology Data Exchange (ETDEWEB)

    Tessema, G.; Vianden, R

    2003-12-31

    Owing to the Coulomb attraction, oppositely charged impurities in semiconductors tend to form pairs when they become mobile. We employed the perturbed angular correlation probe {sup 111}In as an acceptor impurity and studied its interaction with the group VI elements S, Se and Te in Si. They were implanted at room temperature and subsequently the samples were annealed at increasing temperatures in order to remove the implantation-induced damage and increase the mobility of the impurities. After the S and Se implantations, no pair formation was observed. For Te however, a new quadrupole interaction frequency of {nu}{sub Q}=444(1) MHz ({eta}=0) was found, which was attributed to the trapping of a Te atom at the In probe. The formation probability of the In-Te pair and the orientation of the corresponding electric field gradient were studied. The observed properties are compatible with the assumption that a complex between a substitutional In acceptor and a Te atom in the adjacent octahedral interstitial site is formed.

  1. Agent-based reasoning for distributed multi-INT analysis

    Inchiosa, Mario E.; Parker, Miles T.; Perline, Richard

    2006-05-01

    Fully exploiting the intelligence community's exponentially growing data resources will require computational approaches differing radically from those currently available. Intelligence data is massive, distributed, and heterogeneous. Conventional approaches requiring highly structured and centralized data will not meet this challenge. We report on a new approach, Agent-Based Reasoning (ABR). In NIST evaluations, the use of ABR software tripled analysts' solution speed, doubled accuracy, and halved perceived difficulty. ABR makes use of populations of fine-grained, locally interacting agents that collectively reason about intelligence scenarios in a self-organizing, "bottom-up" process akin to those found in biological and other complex systems. Reproduction rules allow agents to make inferences from multi-INT data, while movement rules organize information and optimize reasoning. Complementary deterministic and stochastic agent behaviors enhance reasoning power and flexibility. Agent interaction via small-world networks - such as are found in nervous systems, social networks, and power distribution grids - dramatically increases the rate of discovering intelligence fragments that usefully connect to yield new inferences. Small-world networks also support the distributed processing necessary to address intelligence community data challenges. In addition, we have found that ABR pre-processing can boost the performance of commercial text clustering software. Finally, we have demonstrated interoperability with Knowledge Engineering systems and seen that reasoning across diverse data sources can be a rich source of inferences.

    This short document reports on the second data release of the Kepler-INT Survey (KIS, Greiss et al. 2012). The Kepler field, a 116 sq.deg region of the Cygnus and Lyra constellations, is the target of the most intensive search for transiting planets to date. The Kepler mission provides superior time series photometry, with an enormous impact on all areas of stellar variability. The initial release catalogue (Greiss et al. 2012) concerned data taken between May and August 2011, using the Isaac Newton Telescope on the island of La Palma. Four broadband filters were used, U, g, r, i, as well as one narrowband one, H-alpha, reaching down to a limit of ~20th mag in the Vega system. Observations covering ~50 sq.deg passed our quality control thresholds and constituted the first data release. Here we report on the second data release, covering an additional ~63 sq.deg of the Kepler field. We apply the exact same quality control criteria and photometric calibration as in the initial release catalogue (see Greiss et a...

  3. Structure and function of REP34 implicates carboxypeptidase activity in Francisella tularensis host cell invasion.

    Francisella tularensis is the etiological agent of tularemia, or rabbit fever. Although F. tularensis is a recognized biothreat agent with broad and expanding geographical range, its mechanism of infection and environmental persistence remain poorly understood. Previously, we identified seven F. tularensis proteins that induce a rapid encystment phenotype (REP) in the free-living amoeba, Acanthamoeba castellanii. Encystment is essential to the pathogen's long term intracellular survival in the amoeba. Here, we characterize the cellular and molecular function of REP34, a REP protein with a mass of 34 kDa. A REP34 knock-out strain of F. tularensis has a reduced ability to both induce encystment in A. castellanii and invade human macrophages. We determined the crystal structure of REP34 to 2.05-Å resolution and demonstrate robust carboxypeptidase B-like activity for the enzyme. REP34 is a zinc-containing monomeric protein with close structural homology to the metallocarboxypeptidase family of peptidases. REP34 possesses a novel topology and substrate binding pocket that deviates from the canonical funnelin structure of carboxypeptidases, putatively resulting in a catalytic role for a conserved tyrosine and distinct S1' recognition site. Taken together, these results identify REP34 as an active carboxypeptidase, implicate the enzyme as a potential key F. tularensis effector protein, and may help elucidate a mechanistic understanding of F. tularensis infection of phagocytic cells.

    Manufacturing low density targets in the numbers needed for high rep rate experiments is highly challenging. This report summarises advances from manual production to semiautomated and the improvements that follow both in terms of production time and target uniformity. The production process is described and shown to be improved by the integration of an xyz robot with dispensing capabilities. Results are obtained from manual and semiautomated production runs and compared. The variance in the foam thickness is reduced significantly which should decrease experimental variation due to target parameters and could allow for whole batches to be characterised by the measurement of a few samples. The work applies to both foil backed and free standing foam targets.

    2010-01-01

    We give negative answers to certain questions on abelian semisimple tensor categories raised by Bruno Kahn and Charles A. Weibel in connection with the preprint of Kahn "On the multiplicities of a motive" (arXiv:math/0610446), now published as Parts I and IV of "Zeta functions and motives", Pure Appl. Math. Q. 5 (2009), no. 1, part 2, 507-570. For the most interesting examples we used Deligne's category Rep(S_t,F) of representations of the "symmetric group S_t with t not an integer" with F any algebraically closed field of characteristic zero. This is an interesting family of tensor categories, "new" in some sense, interpolating the representations of the symmetric groups. Among other things we give two proofs that this category is not Schur-finite, showing hence explicitly that it is not tensor equivalent to a category of superepresentations of a supergroup.

    This paper describes the first data release of the Kepler-INT Survey (KIS) that covers a 116 deg{sup 2} region of the Cygnus and Lyra constellations. The Kepler field is the target of the most intensive search for transiting planets to date. Despite the fact that the Kepler mission provides superior time-series photometry, with an enormous impact on all areas of stellar variability, its field lacks optical photometry complete to the confusion limit of the Kepler instrument necessary for selecting various classes of targets. For this reason, we follow the observing strategy and data reduction method used in the IPHAS and UVEX galactic plane surveys in order to produce a deep optical survey of the Kepler field. This initial release concerns data taken between 2011 May and August, using the Isaac Newton Telescope on the island of La Palma. Four broadband filters were used, U, g, r, i, as well as one narrowband one, H{alpha}, reaching down to a 10{sigma} limit of {approx}20th mag in the Vega system. Observations covering {approx}50 deg{sup 2}, thus about half of the field, passed our quality control thresholds and constitute this first data release. We derive a global photometric calibration by placing the KIS magnitudes as close as possible to the Kepler Input Catalog (KIC) photometry. The initial data release catalog containing around 6 million sources from all the good photometric fields is available for download from the KIS Web site (www.astro.warwick.ac.uk/research/kis/) as well as via MAST (KIS magnitudes can be retrieved using the MAST enhanced target search page http://archive.stsci.edu/kepler/kepler{sub f}ov/search.php and also via Casjobs at MAST Web site http://mastweb.stsci.edu/kplrcasjobs/).

    Full Text Available Stressed on crop can be monitored using different indices. Red Edge position is good estimator for stress monitoring. The red edge position (REP is strongly correlated with foliar chlorophyll content. Strong chlorophyll absorption causes the abrupt change in the 680–800 nm region of reflectance spectra of green vegetation. The red edge consist the point of maximum slope between red and near-infrared wavelengths. REP can be used to recognize green zone of the observation area. The REP is present in spectra for vegetation recorded by remote sensing methods. REP is clearer and significant in hyper spectral data as hyper spectral consist of more and continuous bands data. In this paper experiments were carried out for mulberry crop using USGS EO-1 Hyperion data. Atmospheric corrected data is used for classification. Classification is carried out on small cluster of 14 field samples. Ground truth is verified and classified by comparing with Hyperion data. REP is different for different stressed condition of crops and shows healthy and diseased crop condition. Nutritional stresses, diseases, drought of plants are detected using REP. Stressed and healthy field of mulberry are estimated by calculating REP using maximum first derivative, linear interpolation, linear extrapolation method. Finally REP is compared using above methods. It is noticeable difference of REP for healthy and stressed crop. The research indicates that overall accuracy using maximum first derivative was 92.85 % and it was more compared to other methods. Linear extrapolation gives less accuracy compared to linear interpolation method.

  14. Two families of rep-like genes that probably originated by interspecies recombination are represented in viral, plasmid, bacterial, and parasitic protozoan genomes.

    2006-06-01

    Two families of genes related to, and including, rolling circle replication initiator protein (Rep) genes were defined by sequence similarity and by evidence of intergene family recombination. The Rep genes of circoviruses were the best characterized members of the "RecRep1 family." Other members of the RecRep1 family were Rep-like genes found in the genomes of the Canarypox virus, Entamoeba histolytica, and Giardia duodenalis and in a plasmid, p4M, from the Gram-positive bacterium, Bifidobacterium pseudocatenulatum. The "RecRep2 family" comprised some previously identified Rep-like genes from plasmids of phytoplasmas and similar Rep-like genes from the genomes of Lactobacillus acidophilus, Lactococcus lactis, and Phytoplasma asteris. Both RecRep1 and RecRep2 proteins have a nucleotide-binding domain significantly similar to the helicases (2C proteins) of picorna-like viruses. On the N-terminal side of the nucleotide binding domain, RecRep1 proteins have a domain significantly similar to one found in nanovirus Reps, whereas RecRep2 proteins have a domain significantly similar to one in the Reps of pLS1 plasmids. We speculate that RecRep genes have been transferred from viruses or plasmids to parasitic protozoan and bacterial genomes and that Rep proteins were themselves involved in the original recombination events that generated the ancestral RecRep genes.

  15. DNA structure modulates the oligomerization properties of the AAV initiator protein Rep68.

    Directory of Open Access Journals (Sweden)

    Jorge Mansilla-Soto

    2009-07-01

    Full Text Available Rep68 is a multifunctional protein of the adeno-associated virus (AAV, a parvovirus that is mostly known for its promise as a gene therapy vector. In addition to its role as initiator in viral DNA replication, Rep68 is essential for site-specific integration of the AAV genome into human chromosome 19. Rep68 is a member of the superfamily 3 (SF3 helicases, along with the well-studied initiator proteins simian virus 40 large T antigen (SV40-LTag and bovine papillomavirus (BPV E1. Structurally, SF3 helicases share two domains, a DNA origin interaction domain (OID and an AAA(+ motor domain. The AAA(+ motor domain is also a structural feature of cellular initiators and it functions as a platform for initiator oligomerization. Here, we studied Rep68 oligomerization in vitro in the presence of different DNA substrates using a variety of biophysical techniques and cryo-EM. We found that a dsDNA region of the AAV origin promotes the formation of a complex containing five Rep68 subunits. Interestingly, non-specific ssDNA promotes the formation of a double-ring Rep68, a known structure formed by the LTag and E1 initiator proteins. The Rep68 ring symmetry is 8-fold, thus differing from the hexameric rings formed by the other SF3 helicases. However, similiar to LTag and E1, Rep68 rings are oriented head-to-head, suggesting that DNA unwinding by the complex proceeds bidirectionally. This novel Rep68 quaternary structure requires both the DNA binding and AAA(+ domains, indicating cooperativity between these regions during oligomerization in vitro. Our study clearly demonstrates that Rep68 can oligomerize through two distinct oligomerization pathways, which depend on both the DNA structure and cooperativity of Rep68 domains. These findings provide insight into the dynamics and oligomeric adaptability of Rep68 and serve as a step towards understanding the role of this multifunctional protein during AAV DNA replication and site-specific integration.

  16. GSTCD and INTS12 regulation and expression in the human lung.

    Directory of Open Access Journals (Sweden)

    Ma'en Obeidat

    Full Text Available Genome-Wide Association Study (GWAS meta-analyses have identified a strong association signal for lung function, which maps to a region on 4q24 containing two oppositely transcribed genes: glutathione S-transferase, C-terminal domain containing (GSTCD and integrator complex subunit 12 (INTS12. Both genes were found to be expressed in a range of human airway cell types. The promoter regions and transcription start sites were determined in mRNA from human lung and a novel splice variant was identified for each gene. We obtained the following evidence for GSTCD and INTS12 co-regulation and expression: (i correlated mRNA expression was observed both via Q-PCR and in a lung expression quantitative trait loci (eQTL study, (ii induction of both GSTCD and INTS12 mRNA expression in human airway smooth muscle cells was seen in response to TGFβ1, (iii a lung eQTL study revealed that both GSTCD and INTS12 mRNA levels positively correlate with percent predicted FEV1, and (iv FEV1 GWAS associated SNPs in 4q24 were found to act as an eQTL for INTS12 in a number of tissues. In fixed sections of human lung tissue, GSTCD protein expression was ubiquitous, whereas INTS12 expression was predominantly in epithelial cells and pneumocytes. During human fetal lung development, GSTCD protein expression was observed to be highest at the earlier pseudoglandular stage (10-12 weeks compared with the later canalicular stage (17-19 weeks, whereas INTS12 expression levels did not alter throughout these stages. Knowledge of the transcriptional and translational regulation and expression of GSTCD and INTS12 provides important insights into the potential role of these genes in determining lung function. Future work is warranted to fully define the functions of INTS12 and GSTCD.

    Full Text Available http://dx.doi.org/10.5007/1806-5023.2014v11n2p42 Qual é a relação entre as teorias política clássica e contemporânea? O principal objetivo desse trabalho é responder a referida questão. Em termos metodológicos, examinam-se alguns conceitos analisados por James Madison e Robert Dahl em perspectiva comparada. Em particular, o foco repousa sobre as noções madisonianas de facção, separação de poderes e república e sobre o conceito de poliarquia proposto por Dahl. Dessa maneira, descrevemos a continua influência de certos aspectos próprios da teoria política clássica no modo como a teoria contemporânea lida com o tema. Concluímos que a contribuição dos autores clássicos permite que a teoria política contemporânea seja capaz de tentar oferecer explicações mais robustas aos “novos” problemas enfrentados pela disciplina.

  7. Metal-Induced Stabilization and Activation of Plasmid Replication Initiator RepB

    Initiation of plasmid rolling circle replication (RCR) is catalyzed by a plasmid-encoded Rep protein that performs a Tyr- and metal-dependent site-specific cleavage of one DNA strand within the double-strand origin (dso) of replication. The crystal structure of RepB, the initiator protein of the streptococcal plasmid pMV158, constitutes the first example of a Rep protein structure from RCR plasmids. It forms a toroidal homohexameric ring where each RepB protomer consists of two domains: the C-terminal domain involved in oligomerization and the N-terminal domain containing the DNA-binding and endonuclease activities. Binding of Mn2+ to the active site is essential for the catalytic activity of RepB. In this work, we have studied the effects of metal binding on the structure and thermostability of full-length hexameric RepB and each of its separate domains by using different biophysical approaches. The analysis of the temperature-induced changes in RepB shows that the first thermal transition, which occurs at a range of temperatures physiologically relevant for the pMV158 pneumococcal host, represents an irreversible conformational change that affects the secondary and tertiary structure of the protein, which becomes prone to self-associate. This transition, which is also shown to result in loss of DNA binding capacity and catalytic activity of RepB, is confined to its N-terminal domain. Mn2+ protects the protein from undergoing this detrimental conformational change and the observed protection correlates well with the high-affinity binding of the cation to the active site, as substituting one of the metal-ligands at this site impairs both the protein affinity for Mn2+and the Mn2+-driven thermostabilization effect. The level of catalytic activity of the protein, especially in the case of full-length RepB, cannot be explained based only on the high-affinity binding of Mn2+ at the active site and suggests the existence of additional, lower-affinity metal binding site

    The Rudiviridae are a family of rod-shaped archaeal viruses with covalently closed, linear double-stranded DNA (dsDNA) genomes. Their replication mechanisms remain obscure, although parallels have been drawn to the Poxviridae and other large cytoplasmic eukaryotic viruses. Here we report that a protein encoded in the 34-kbp genome of the rudivirus SIRV1 is a member of the replication initiator (Rep) superfamily of proteins, which initiate rolling-circle replication (RCR) of diverse viruses and plasmids. We show that SIRV Rep nicks the viral hairpin terminus, forming a covalent adduct between an active-site tyrosine and the 5′ end of the DNA, releasing a 3′ DNA end as a primer for DNA synthesis. The enzyme can also catalyze the joining reaction that is necessary to reseal the DNA hairpin and terminate replication. The dimeric structure points to a simple mechanism through which two closely positioned active sites, each with a single tyrosine residue, work in tandem to catalyze DNA nicking and joining. We propose a novel mechanism for rudivirus DNA replication, incorporating the first known example of a Rep protein that is not linked to RCR. The implications for Rep protein function and viral replication are discussed. PMID:21068244

    The paper presents technical aspects of rep-PCR fingerprinting technique and compares its typing abilities, differentiation power and reproducibility with other recognised and recommended genotyping methods. Although rep-PCR fingerprinting is similar to MAAP techniques, it demonstrates some essentially different elements. The data presented in this review, indicate a rep-PCR genomic fingerprinting technique as a highly discriminating, independent screening method for determining the taxonomical diversity of bacterial population.

    Comparative genome analysis of Enterococcus faecium recently revealed that a genomic island containing the esp gene, referred to as the esp-containing pathogenicity island (esp PAI), can be transferred by conjugation and contains a partial Tn916-like element and an integrase gene, intA. Here, we characterize the role of intA in the excision of the esp PAI. An intA insertion-deletion mutant in E. faecium E1162 (E1162ΔintA) was constructed and in trans complemented with wild-type intA (E1162ΔintA::pEF30). Circular intermediates (CI) of excised esp PAI were determined using inverse PCR analysis on purified chromosomal DNA from strains E1162, E1162Δesp, E1162ΔintA, and E1162ΔintA::pEF30. In E1162 and E1162Δesp, CI of the esp PAI were detected. No CI were detected in E1162ΔintA, while in the complemented strain E1162ΔintA::pEF30 CI formation was restored, indicating that intA is essential for excision and subsequent mobilization of the esp-containing genomic island in E. faecium. Based on the fact that this island can be mobilized and is self-transmissible, we propose to change the name of the esp PAI to ICEEfm1.

  12. Initial characterization of the Pf-Int recombinase from the malaria parasite Plasmodium falciparum.

    Directory of Open Access Journals (Sweden)

    Mehdi Ghorbal

    Full Text Available BACKGROUND: Genetic variation is an essential means of evolution and adaptation in many organisms in response to environmental change. Certain DNA alterations can be carried out by site-specific recombinases (SSRs that fall into two families: the serine and the tyrosine recombinases. SSRs are seldom found in eukaryotes. A gene homologous to a tyrosine site-specific recombinase has been identified in the genome of Plasmodium falciparum. The sequence is highly conserved among five other members of Plasmodia. METHODOLOGY/PRINCIPAL FINDINGS: The predicted open reading frame encodes for a ∼57 kDa protein containing a C-terminal domain including the putative tyrosine recombinase conserved active site residues R-H-R-(H/W-Y. The N-terminus has the typical alpha-helical bundle and potentially a mixed alpha-beta domain resembling that of λ-Int. Pf-Int mRNA is expressed differentially during the P. falciparum erythrocytic life stages, peaking in the schizont stage. Recombinant Pf-Int and affinity chromatography of DNA from genomic or synthetic origin were used to identify potential DNA targets after sequencing or micro-array hybridization. Interestingly, the sequences captured also included highly variable subtelomeric genes such as var, rif, and stevor sequences. Electrophoretic mobility shift assays with DNA were carried out to verify Pf-Int/DNA binding. Finally, Pf-Int knock-out parasites were created in order to investigate the biological role of Pf-Int. CONCLUSIONS/SIGNIFICANCE: Our data identify for the first time a malaria parasite gene with structural and functional features of recombinases. Pf-Int may bind to and alter DNA, either in a sequence specific or in a non-specific fashion, and may contribute to programmed or random DNA rearrangements. Pf-Int is the first molecular player identified with a potential role in genome plasticity in this pathogen. Finally, Pf-Int knock-out parasite is viable showing no detectable impact on blood stage

    ABSTRACT The genomic DNA fingerprinting technique known as repetitive-sequence-based polymerase chain reaction (rep-PCR) was evaluated as a tool to differentiate subspecies of Clavibacter michiganensis, with special emphasis on C. michiganensis subsp. michiganensis, the pathogen responsible for bacterial canker of tomato. DNA primers (REP, ERIC, and BOX), corresponding to conserved repetitive element motifs in the genomes of diverse bacterial species, were used to generate genomic fingerprints of C. michiganensis subsp. michiganensis, C. michiganensis subsp. sepedonicus, C. michiganensis subsp. nebraskensis, C. michiganensis subsp. tessellarius, and C. michiganensis subsp. insidiosum. The rep-PCR-generated patterns of DNA fragments observed after agarose gel electrophoresis support the current division of C. michiganensis into five subspecies. In addition, the rep-PCR fingerprints identified at least four types (A, B, C, and D) within C. michiganensis subsp. michiganensis based on limited DNA polymorphisms; the ability to differentiate individual strains may be of potential use in studies on the epidemiology and host-pathogen interactions of this organism. In addition, we have recovered from diseased tomato plants a relatively large number of naturally occurring avirulent C. michiganensis subsp. michiganensis strains with rep-PCR fingerprints identical to those of virulent C. michiganensis subsp. michiganensis strains.

The mechanism of subsequent steps of the replication process, e.g. helicase activity to drive fork-elongation, etc. has largely remained obscure. Here we show that Rep of a geminivirus, namely, Mungbean yellow mosaic India virus (MYMIV), acts as a replicative helicase. The Rep-helicase, requiring > or =6 nt space for its efficient activity, translocates in the 3'-->5' direction, and the presence of forked junction in the substrate does not influence the activity to any great extent. Rep forms a large oligomeric complex and the helicase activity is dependent on the oligomeric conformation ( approximately 24mer). The role of Rep as a replicative helicase has been demonstrated through ex vivo studies in Saccharomyces cerevisiae and in planta analyses in Nicotiana tabacum. We also establish that such helicase activity is not confined to the MYMIV system alone, but is also true with at least two other begomoviruses, viz., Mungbean yellow mosaic virus (MYMV) and Indian cassava mosaic virus (ICMV).

    It is known that the number of ImC, expressing myeloid markers, CD11b and Gr-1, increase with tumor growth and ImC play a role in the escape of tumor cells from immunosurveillance in tumor-bearing mice and cancer patients. However, the mechanisms by which ImC suppress immune responses in tumor-bearing mice have not been completely elucidated. In the present study, we investigated the function of splenic ImC freshly isolated from tumor-bearing mice and splenic ImC differentiated in vitro by GM-CSF. Freshly isolated splenic ImC were divided into two groups depending on Gr-1 expression, Gr-1 high (Gr-1hi) and intermediate (Gr-1int). Freshly isolated splenic Gr-1int ImC, but not Gr-1hi ImC, from tumor-bearing mice reduced production of IFN-gamma in CD8+ T cells, but neither splenic Gr-1int ImC nor Gr-1hi ImC isolated from naive mice did. Both Gr-1int and Gr-1hi ImC differentiated in vitro by GM-CSF inhibited production of IFN-gamma in both CD8+ and CD4+ T cells. In addition, the differentiated Gr-1int ImC, one-third of which were CD11c+F4/80+ cells, and their culture supernatants suppressed proliferative responses of T cells stimulated by CD3 ligation, but the differentiated Gr-1hi ImC and their culture supernatants did not. These results suggest that Gr-1int ImC are altered to immune-suppressive cells in tumor circumstances and that they are differentiated by GM-CSF progressively into CD11c+F4/80+ cells with further suppressive activity against T cells.

    Studies over the last decade have shown radioisotope-based nuclear electric propulsion to be enhancing and, in some cases, enabling for many potential robotic science missions. Also known as radioisotope electric propulsion (REP), the technology offers the performance advantages of traditional reactor-powered electric propulsion (i.e., high specific impulse propulsion at large distances from the Sun), but with much smaller, affordable spacecraft. Future use of REP requires development of radioisotope power sources with system specific powers well above that of current systems. The US Department of Energy and NASA have developed an advanced Stirling radioisotope generator (ASRG) engineering unit, which was subjected to rigorous flight qualification-level tests in 2008, and began extended lifetime testing later that year. This advancement, along with recent work on small ion thrusters and life extension technology for Hall thrusters, could enable missions using REP sometime during the next decade.

  17. Spreading the Eco-Message: Using Proactive Coping to Aid Eco-Rep Behavior Change Programming

    Full Text Available Making pro-environmental behavior changes can be difficult, particularly when these changes challenge daily routines and comfortable lifestyles. We designed and implemented an eco-representative intervention program to help students reduce their energy use by proactively coping with barriers to pro-environmental behavior change, and then communicate effective behavior change strategies to student peers. Twenty-nine first-year college students participated in a four-week proactive coping training to change five environmentally impactful behaviors and then spread behavior change messages to fellow residents during a two-week energy challenge. Eco-reps successfully changed their own behaviors in a pro-environmental direction by generating important barriers and successful facilitators for behavior change, and eco-rep residence halls were more likely to reduce energy and maintain reductions compared to non-eco-rep halls. Implications for future environmental behavior change interventions are discussed.

  18. DIMENSION VARIATION OF FEATURE-BASED MODEL BY OPERATING DIRECTLY ON B-REP

    A new algorithm for dimension variation of feature-based models is developed.The algorithm is based on B-Rep/CSG hybrid scheme and operates directly on B-Rep.Product information (including the features locating dimensions and other data for manufacture) will not lose after model variation and modification.Furthermore, the definition and solution of features constraints are also supported.The scheme of directly operating on B-Rep overcomes many drawbacks of other proposed methods, most of which need to redo all of the previous work to implement dimension variation, so the computational cost is expensive and product information will lose.What is presented in this paper makes a new way in the area of parametric design.

  20. Resolution of Mismatched Overlap Holliday Junction Intermediates by the Tyrosine Recombinase IntDOT.

    CTnDOT is an integrated conjugative element found in Bacteroides species. CTnDOT contains and transfers antibiotic resistance genes. The element integrates into and excises from the host chromosome via a Holliday junction (HJ) intermediate as part of a site-specific recombination mechanism. The CTnDOT integrase, IntDOT, is a tyrosine recombinase with core-binding, catalytic, and amino-terminal (N) domains. Unlike well-studied tyrosine recombinases, such as lambda integrase (Int), IntDOT is able to resolve Holliday junctions containing heterology (mismatched bases) between the sites of strand exchange. All known natural isolates of CTnDOT contain mismatches in the overlap region between the sites of strand exchange. Previous work showed that IntDOT was unable to resolve synthetic Holliday junctions containing mismatched bases to products in the absence of the arm-type sites and a DNA-bending protein. We constructed synthetic HJs with the arm-type sites and tested them with the Bacteroides host factor (BHFa). We found that the addition of BHFa stimulated resolution of HJ intermediates with mismatched overlap regions to products. In addition, the L1 site is required for directionality of the reaction, particularly when the HJ contains mismatches. BHFa is required for product formation when the overlap region contains mismatches, and it stimulates resolution to products when the overlap region is identical. Without this DNA bending, the N domain of IntDOT is likely unable to bind the L1 arm-type site. These findings suggest that BHFa bends DNA into the necessary conformation for the higher-order complexes, including the L1 site, that are required for product formation.IMPORTANCE CTnDOT is a mobile element that carries antibiotic resistance genes and moves by site-selective recombination and subsequent conjugation. The recombination reaction is catalyzed by an integrase IntDOT that is a member of the tyrosine recombinase family. The reaction proceeds through ordered

  9. Resolution of Holliday junction recombination intermediates by wild-type and mutant IntDOT proteins.

    CTnDOT encodes an integrase that is a member of the tyrosine recombinase family. The recombination reaction proceeds by sequential sets of genetic exchanges between the attDOT site in CTnDOT and an attB site in the chromosome. The exchanges are separated by 7 base pairs in each site. Unlike most tyrosine recombinases, IntDOT exchanges sites that contain different DNA sequences between the exchange sites to generate Holliday junctions (HJs) that contain mismatched bases. We demonstrate that IntDOT resolves synthetic HJs in vitro. Holliday junctions that contain identical sequences between the exchange sites are resolved into both substrates and products, while HJs that contain mismatches are resolved only to substrates. This result implies that resolution of HJs to products requires the formation of a higher-order nucleoprotein complex with natural sites containing IntDOT. We also found that proteins with substitutions of residues (V95, K94, and K96) in a putative alpha helix at the junction of the N and CB domains (coupler region) were defective in resolving HJs. Mutational analysis of charged residues in the coupler and the N terminus of the protein did not provide evidence for a charge interaction between the regions of the protein. V95 may participate in a hydrophobic interaction with another region of IntDOT.

    This two-part study investigated the genetic diversity and transmission of Streptococcus mutans using the DiversiLab repetitive extragenic palindromic PCR (rep-PCR) approach. For children with S. mutans and participating household members, analysis for evidence of unrelated child-to-child as well as intra-familial transmission was evaluated based on commonality of genotypes. A total of 169 index children and 425 household family members from Uniontown, Alabama were evaluated for genetic diversity using rep-PCR. Thirty-four unique rep-PCR genotypes were observed for 13,906 S. mutans isolates. For transmission, 117 child and household isolates were evaluated for shared genotype (by child and by genotype cases, multiple matches possible for each child). Overall, children had 1-9 genotypes and those with multiple genotypes were 2.3 times more likely to have caries experience (decayed, missing and filled teeth/surfaces>0). Only 28% of children shared all genotypes within the household, while 72% had at least 1 genotype not shared with anyone in the household. Children had genotype(s) not shared with any household members in 157 cases. In 158 cases children and household members shared a genotype in which 55% (87/158 cases) were shared with more than one family member. Children most frequently shared genotypes with their mothers (54%; 85/158), siblings (46%; 72/158) and cousins (23%; 37/158). A reference library for S. mutans for epidemiological surveillance using the DiversiLab rep-PCR approach is detailed. The genetic diversity of S. mutans in this population demonstrated frequent commonality of genotypes. Evidence for both child-to-child and intra-familial transmission of S. mutans was observed by rep-PCR.

    Upon binding to short specific dsDNA sequences in vitro, the N-terminal WH1 domain of the plasmid DNA replication initiator RepA assembles as amyloid fibres. These are bundles of single or double twisted tubular filaments in which distorted RepA-WH1 monomers are the building blocks. When expressed in Escherichia coli, RepA-WH1 triggers the first synthetic amyloid proteinopathy in bacteria, recapitulating some of the features of mammalian prion diseases: it is vertically transmissible, albeit non-infectious, showing up in at least two phenotypically distinct and interconvertible strains. Here we report B3h7, a monoclonal antibody specific for oligomers of RepA-WH1, but which does not recognize the mature amyloid fibres. Unlike a control polyclonal antibody generated against the soluble protein, B3h7 interferes in vitro with DNA-promoted or amyloid-seeded assembly of RepA-WH1 fibres, thus the targeted oligomers are on-pathway amyloidogenic intermediates. Immuno-electron microscopy with B3h7 on thin sections of E. coli cells expressing RepA-WH1 consistently labels the bacterial nucleoid, but not the large cytoplasmic aggregates of the protein. This observation points to the nucleoid as the place where oligomeric amyloid precursors of RepA-WH1 are generated, and suggests that, once nucleated by DNA, further growth must continue in the cytoplasm due to entropic exclusion.

  6. RepSeq – A database of amino acid repeats present in lower eukaryotic pathogens

    Smith Deborah F

    2007-04-01

    Full Text Available Abstract Background Amino acid repeat-containing proteins have a broad range of functions and their identification is of relevance to many experimental biologists. In human-infective protozoan parasites (such as the Kinetoplastid and Plasmodium species, they are implicated in immune evasion and have been shown to influence virulence and pathogenicity. RepSeq http://repseq.gugbe.com is a new database of amino acid repeat-containing proteins found in lower eukaryotic pathogens. The RepSeq database is accessed via a web-based application which also provides links to related online tools and databases for further analyses. Results The RepSeq algorithm typically identifies more than 98% of repeat-containing proteins and is capable of identifying both perfect and mismatch repeats. The proportion of proteins that contain repeat elements varies greatly between different families and even species (3–35% of the total protein content. The most common motif type is the Sequence Repeat Region (SRR – a repeated motif containing multiple different amino acid types. Proteins containing Single Amino Acid Repeats (SAARs and Di-Peptide Repeats (DPRs typically account for 0.5–1.0% of the total protein number. Notable exceptions are P. falciparum and D. discoideum, in which 33.67% and 34.28% respectively of the predicted proteomes consist of repeat-containing proteins. These numbers are due to large insertions of low complexity single and multi-codon repeat regions. Conclusion The RepSeq database provides a repository for repeat-containing proteins found in parasitic protozoa. The database allows for both individual and cross-species proteome analyses and also allows users to upload sequences of interest for analysis by the RepSeq algorithm. Identification of repeat-containing proteins provides researchers with a defined subset of proteins which can be analysed by expression profiling and functional characterisation, thereby facilitating study of pathogenicity

  7. ReRep: Computational detection of repetitive sequences in genome survey sequences (GSS

    Directory of Open Access Journals (Sweden)

    Alves-Ferreira Marcelo

    2008-09-01

    Full Text Available Abstract Background Genome survey sequences (GSS offer a preliminary global view of a genome since, unlike ESTs, they cover coding as well as non-coding DNA and include repetitive regions of the genome. A more precise estimation of the nature, quantity and variability of repetitive sequences very early in a genome sequencing project is of considerable importance, as such data strongly influence the estimation of genome coverage, library quality and progress in scaffold construction. Also, the elimination of repetitive sequences from the initial assembly process is important to avoid errors and unnecessary complexity. Repetitive sequences are also of interest in a variety of other studies, for instance as molecular markers. Results We designed and implemented a straightforward pipeline called ReRep, which combines bioinformatics tools for identifying repetitive structures in a GSS dataset. In a case study, we first applied the pipeline to a set of 970 GSSs, sequenced in our laboratory from the human pathogen Leishmania braziliensis, the causative agent of leishmaniosis, an important public health problem in Brazil. We also verified the applicability of ReRep to new sequencing technologies using a set of 454-reads of an Escheria coli. The behaviour of several parameters in the algorithm is evaluated and suggestions are made for tuning of the analysis. Conclusion The ReRep approach for identification of repetitive elements in GSS datasets proved to be straightforward and efficient. Several potential repetitive sequences were found in a L. braziliensis GSS dataset generated in our laboratory, and further validated by the analysis of a more complete genomic dataset from the EMBL and Sanger Centre databases. ReRep also identified most of the E. coli K12 repeats prior to assembly in an example dataset obtained by automated sequencing using 454 technology. The parameters controlling the algorithm behaved consistently and may be tuned to the properties

    The DNA binding domain of transposon Tn916 integrase (INT-DBD) binds to DNA target site by positioning the face of a three-stranded antiparallel β-sheet within the major groove. As the negatively charged DNA directly interacts with the positively charged residues (such as Arg and Lys) of INT-DBD, the electrostatic interaction is expected to play an important role in the dynamical stability of the protein-DNA binding complex. In the current work, the combined use of quantum-based polarized protein-specific charge (PPC) for protein and polarized nucleic acid-specific charge (PNC) for DNA were employed in molecular dynamics simulation to study the interaction dynamics between INT-DBD and DNA. Our study shows that the protein-DNA structure is stabilized by polarization and the calculated protein-DNA binding free energy is in good agreement with the experimental data. Furthermore, our study revealed a positive correlation between the measured binding energy difference in alanine mutation and the occupancy of the corresponding residue's hydrogen bond. This correlation relation directly relates the contribution of a specific residue to protein-DNA binding energy to the strength of the hydrogen bond formed between the specific residue and DNA.

  9. Functionality of in vitro reconstituted group II intron RmInt1-derived ribonucleoprotein particles

    Full Text Available The functional unit of mobile group II introns is a ribonucleoprotein particle (RNP consisting of the intron-encoded protein (IEP and the excised intron RNA. The IEP has reverse transcriptase activity but also promotes RNA splicing, and the RNA-protein complex triggers site-specific DNA insertion by reverse splicing, in a process called retrohoming. In vitro reconstituted ribonucleoprotein complexes from the Lactococcus lactis group II intron Ll.LtrB, which produce a double strand break, have recently been studied as a means of developing group II intron-based gene targeting methods for higher organisms. The Sinorhizobium meliloti group II intron RmInt1 is an efficient mobile retroelement, the dispersal of which appears to be linked to transient single-stranded DNA during replication. The RmInt1IEP lacks the endonuclease domain (En and cannot cut the bottom strand to generate the 3’ end to initiate reverse transcription. We used an Escherichia coli expression system to produce soluble and active RmInt1 IEP and reconstituted RNPs with purified components in vitro. The RNPs generated were functional and reverse-spliced into a single-stranded DNA target. This work constitutes the starting point for the use of group II introns lacking DNA endonuclease domain-derived RNPs for highly specific gene targeting methods.

  10. The N-terminus of IntDOT forms hydrophobic interactions during Holliday Junction resolution.

    Science.gov (United States)

    Kolakowski, Adam J; Gardner, Jeffrey F

    DOT Integrase (IntDOT) is a member of the tyrosine recombinase family. It catalyzes the integration and excision reactions of an integrative and conjugative element (ICE) called CTnDOT. Like other tyrosine recombinases, the integration reaction proceeds by two sets of strand exchanges between the attDOT site on CTnDOT and an attB site in the host chromosome. The strand exchanges occur seven bases apart and define an overlap region. After the first strand exchanges a Holliday Junction (HJ) intermediate is formed. Previous work showed that a valine (V95) in a predicted alpha helix in the N-terminus of IntDOT is required for resolution of HJs to substrates and products. We have identified two additional hydrophobic residues in the helix (A92 and F99) that are involved in resolution of HJs. IntDOT proteins with substitutions at these residues form aberrant complexes in an electrophoretic mobility shift assay. We propose that these three residues participate in hydrophobic interactions that are involved in forming higher-order complexes and resolution of HJs. Copyright © 2016 Elsevier B.V.

    Understanding the origin of intrinsically low thermal conductivity is fundamentally important to the development of high-performance thermoelectric materials, which can convert waste-heat into electricity. Herein, we report an ultralow lattice thermal conductivity (ca. 0.4 W m(-1)  K(-1) ) in mixed valent InTe (that is, In(+) In(3+) Te2 ), which exhibits an intrinsic bonding asymmetry with coexistent covalent and ionic substructures. The phonon dispersion of InTe exhibits, along with low-energy flat branches, weak instabilities associated with the rattling vibrations of In(+) atoms along the columnar ionic substructure. These weakly unstable phonons originate from the 5s(2) lone pair of the In(+) atom and are strongly anharmonic, which scatter the heat-carrying acoustic phonons through strong anharmonic phonon-phonon interactions, as evident in anomalously high mode Grüneisen parameters. A maximum thermoelectric figure of merit (z T) of about 0.9 is achieved at 600 K for the 0.3 mol % In-deficient sample, making InTe a promising material for mid-temperature thermoelectric applications.

    Andrés Obregón-Henao

    Full Text Available BACKGROUND: Tuberculosis is one of the world's leading killers, stealing 1.4 million lives and causing 8.7 million new and relapsed infections in 2011. The only vaccine against tuberculosis is BCG which demonstrates variable efficacy in adults worldwide. Human infection with Mycobacterium tuberculosis results in the influx of inflammatory cells to the lung in an attempt to wall off bacilli by forming a granuloma. Gr1(intCD11b(+ cells are called myeloid-derived suppressor cells (MDSC and play a major role in regulation of inflammation in many pathological conditions. Although MDSC have been described primarily in cancer their function in tuberculosis remains unknown. During M. tuberculosis infection it is crucial to understand the function of cells involved in the regulation of inflammation during granuloma formation. Understanding their relative impact on the bacilli and other cellular phenotypes is necessary for future vaccine and drug design. METHODOLOGY/PRINCIPAL FINDINGS: We compared the bacterial burden, lung pathology and Gr1(intCD11b(+ myeloid-derived suppressor cell immune responses in M. tuberculosis infected NOS2-/-, RAG-/-, C3HeB/FeJ and C57/BL6 mice. Gr-1(+ cells could be found on the edges of necrotic lung lesions in NOS2-/-, RAG-/-, and C3HeB/FeJ, but were absent in wild-type mice. Both populations of Gr1(+CD11b(+ cells expressed high levels of arginase-1, and IL-17, additional markers of myeloid derived suppressor cells. We then sorted the Gr1(hi and Gr1(int populations from M. tuberculosis infected NOS-/- mice and placed the sorted both Gr1(int populations at different ratios with naïve or M. tuberculosis infected splenocytes and evaluated their ability to induce activation and proliferation of CD4+T cells. Our results showed that both Gr1(hi and Gr1(int cells were able to induce activation and proliferation of CD4+ T cells.

    1992-01-01

    A study was conducted on the parasitemia detection level and the specificity of the pRepHind DNA probe for diagnosing Plasmodium falciparum by the stain hybridization method. The parasitemia detection level was studied by using dilutions of a P. falciparum in vitro culture, adjusted by direct microscopic examination to 1; 0.1; 0.01; 0.001; 0.0001 and 0.00001% of parasited red cells. Specificity was increased by using DNA extractions from P. Yoelii, P. berghei and human leucocytes. The results showed that the method was able to detect 0.0001% of parasitemia starting from DNA extractions of 100 L infected red cells. The pRepHind probe only detected specifically DNA from P. falciparum. It is concluded that the method is suitable for being used in the diagnosis of infection due to P. falciparum.

    Full Text Available Molecular typing using repetitive sequenced-based PCR (rep-PCR and hsp60 sequencing were applied to a collection of diverse Enterobacter cloacae complex isolates. To determine the most practical method for reference laboratories, we analyzed 71 E. cloacae complex isolates from sporadic and outbreak occurrences originating from 4 geographic areas. While rep-PCR was more discriminating, hsp60 sequencing provided a broader and a more objective geographical tracking method similar to multilocus sequence typing (MLST. In addition, we suggest that MLST may have higher discriminative power compared to hsp60 sequencing, although rep-PCR remains the most discriminative method for local outbreak investigations. In addition, rep-PCR can be an effective and inexpensive method for local outbreak investigation.

    Full Text Available Abstract Background Populus trichocarpa is the first tree genome to be completed, and its whole genome is currently being assembled. No functional annotation about the repetitive elements in the Populus trichocarpa genome is currently available. Results We predicted 9,623 repetitive elements in the Populus trichocarpa genome, and assigned functions to 3,075 of them (31.95%. The 9,623 repetitive elements cover ~40% of the current (partially assembled genome. Among the 9,623 repetitive elements, 668 have copies only in the contigs that have not been assigned to one of the 19 chromosome while the rest all have copies in the partially assembled chromosomes. Conclusion All the predicted data are organized into an easy-to-use web-browsable database, RepPop. Various search capabilities are provided against the RepPop database. A Wiki system has been set up to facilitate functional annotation and curation of the repetitive elements by a community rather than just the database developer. The database RepPop will facilitate the assembling and functional characterization of the Populus trichocarpa genome.

  3. RepARK--de novo creation of repeat libraries from whole-genome NGS reads.

    2014-05-01

    Generation of repeat libraries is a critical step for analysis of complex genomes. In the era of next-generation sequencing (NGS), such libraries are usually produced using a whole-genome shotgun (WGS) derived reference sequence whose completeness greatly influences the quality of derived repeat libraries. We describe here a de novo repeat assembly method--RepARK (Repetitive motif detection by Assembly of Repetitive K-mers)--which avoids potential biases by using abundant k-mers of NGS WGS reads without requiring a reference genome. For validation, repeat consensuses derived from simulated and real Drosophila melanogaster NGS WGS reads were compared to repeat libraries generated by four established methods. RepARK is orders of magnitude faster than the other methods and generates libraries that are: (i) composed almost entirely of repetitive motifs, (ii) more comprehensive and (iii) almost completely annotated by TEclass. Additionally, we show that the RepARK method is applicable to complex genomes like human and can even serve as a diagnostic tool to identify repetitive sequences contaminating NGS datasets.

    The adeno-associated virus (AAV) genome can be stably integrated into the AAVS1 region of human chromosome 19 (19q13.4-qter) with the assistance of Rep68/78 protein.In the current models of AAV integration in a locusspecific manner,the foreign genes were randomly inserted into the AAVS1 region,which contains several functional genes.As random integration in this region may lead to insertion mutations and disrupt normal gene expression or critical signaling pathways of the host cells,it is necessary to find a precise insertion site in the AAVS1 region.Homologous recombination is the most accurate and versatile mechanism for such site-specific integration.To investigate site-specific integration in the AAVS1 region,a targeted vector containing two homologous arms derived from AAVS1 and a reporter gene was transfected into HeLa cells with or without Rep68/78 mRNA.The results indicated that transient expression of Rep68/78 in HeLa cells improved integration of the gene of interest at the AAVS1 locus in a site-specific manner.Compared with locus-specific integration reported in previous studies,sitespecific integration may minimize the risk associated with random DNA integration in the AAVS1 region,which might be helpful for gene therapy.

    Full Text Available The superscalar pipeline is something that the REP architecture resembles. The features that are similar in both architectures include rename, decode, fetch as well as in-order front-ends parts as substituted by dispatch units. The physical register file, execute unit, dynamic scheduler and task queue are contained by the out of-order execution core. The architecture also contains the REP that beholds an integrated system of shared-memory. A number of experiments with realistic benchmarks and an FPGA environment are used to synthesize design. The experiments conducted yielded in results that prove that the new architecture of the REP leads to higher performance of applications because of decreased processing time. And the core reason for the deduction of processing time is the simplified complexity of the frequency and area of the architecture. The results show that the least error tolerance is 1m by particle filter. Also, the optimum iteration level is 20 to get enhanceable navigation data for AUV.

  8. Modulation of pPS10 Host Range by Plasmid-Encoded RepA Initiator Protein

    Maestro, Beatriz; Sanz, Jesús M.; Díaz-Orejas, Ramón; Fernández-Tresguerres, Elena

    2003-01-01

    We report here the isolation and analysis of novel repA host range mutants of pPS10, a plasmid originally found in Pseudomonas savastanoi. Upon hydroxylamine treatment, five plasmid mutants were selected for their establishment in Escherichia coli at 37°C, a temperature at which the wild-type form cannot be established. The mutations were located in different functional regions of the plasmid RepA initiation protein, and the mutants differ in their stable maintenance, copy number, and ability to interact with sequences of the basic replicon. Four of them have broadened their host range, and one of them, unable to replicate in Pseudomonas, has therefore changed its host range. Moreover, the mutants also have increased their replication efficiency in strains other than E. coli such as Pseudomonas putida and Alcaligenes faecalis. None of these mutations drastically changed the structure or thermal stability of the wild-type RepA protein, but in all cases an enhanced interaction with host-encoded DnaA protein was detected by gel filtration chromatography. The effects of the mutations on the functionality of RepA protein are discussed in the framework of a three-dimensional model of the protein. We propose possible explanations for the host range effect of the different repA mutants, including the enhancement of limiting interactions of RepA with specific host replication factors such as DnaA.

  11. Translation initiation of the replication initiator repB gene of promiscuous plasmid pMV158 is led by an extended non-SD sequence.

    RepB is the pMV158-encoded protein that initiates rolling-circle replication of this promiscuous plasmid. Availability of RepB is rate-limiting for the plasmid replication process, and therefore the repB gene encoding the protein is subjected to strict control. Two trans-acting plasmid elements, CopG and the antisense RNAII, are involved in controlling the synthesis of the initiator at the transcriptional and translational level, respectively. In addition to this dual control of repB expression that senses and corrects fluctuations in plasmid copy number, proper availability of RepB also relies on the adequate functionality of the transcription and translation initiation regulatory signals. Translation of repB has been postulated to depend on an atypical ribosome binding site that precedes its start codon, although such a hypothesis has never been proved. To define sequences involved in translation of repB, several mutations in the translation initiation region of the repB mRNA have been characterized by using an Escherichia coli in vitro expression system wherein the synthesis of RepB was detected and quantified. We showed that translation of repB is not coupled to that of copG and depends only on its own initiation signals. The atypical ribosome binding site, as it was defined, is not involved in translation initiation. However, the sequence just upstream of the repB start codon, encompassing the proximal box of the atypical ribosome binding site and the four bases immediately downstream of it, is indeed important for efficient translation of repB. The high degree of conservation of this sequence among the rep genes of plasmids of the same pMV158 family supports its relevancy as a translation initiation signal in mRNAs without a recognizable Shine-Dalgarno sequence.

  18. The integrator complex subunit 6 (Ints6 confines the dorsal organizer in vertebrate embryogenesis.

    Full Text Available Dorsoventral patterning of the embryonic axis relies upon the mutual antagonism of competing signaling pathways to establish a balance between ventralizing BMP signaling and dorsal cell fate specification mediated by the organizer. In zebrafish, the initial embryo-wide domain of BMP signaling is refined into a morphogenetic gradient following activation dorsally of a maternal Wnt pathway. The accumulation of β-catenin in nuclei on the dorsal side of the embryo then leads to repression of BMP signaling dorsally and the induction of dorsal cell fates mediated by Nodal and FGF signaling. A separate Wnt pathway operates zygotically via Wnt8a to limit dorsal cell fate specification and maintain the expression of ventralizing genes in ventrolateral domains. We have isolated a recessive dorsalizing maternal-effect mutation disrupting the gene encoding Integrator Complex Subunit 6 (Ints6. Due to widespread de-repression of dorsal organizer genes, embryos from mutant mothers fail to maintain expression of BMP ligands, fail to fully express vox and ved, two mediators of Wnt8a, display delayed cell movements during gastrulation, and severe dorsalization. Consistent with radial dorsalization, affected embryos display multiple independent axial domains along with ectopic dorsal forerunner cells. Limiting Nodal signaling or restoring BMP signaling restores wild-type patterning to affected embryos. Our results are consistent with a novel role for Ints6 in restricting the vertebrate organizer to a dorsal domain in embryonic patterning.

El lema central se encuentra en el hecho de que las formas de demarcar, definir, cercar el concepto de pedagogía, se relaciona con una voluntad que es la de legislar sobre la sociedad y sus individuos. Con las fecundas transformaciones que han reconfigurado la sociedad y el estado de la cultura, se argumenta que ha habido una necesidad de que la pedagogía se adecuara a estas reconfiguraciones, actuando como intérprete de la cultura –lo que proporcionó, por su vez, la pluralidad del concepto de pedagogía y de las intenciones que la cruzan.

  1. Impact of capsid conformation and Rep-capsid interactions on adeno-associated virus type 2 genome packaging.

    2006-01-01

    Single-stranded genomes of adeno-associated virus (AAV) are packaged into preformed capsids. It has been proposed that packaging is initiated by interaction of genome-bound Rep proteins to the capsid, thereby targeting the genome to the portal of encapsidation. Here we describe a panel of mutants with amino acid exchanges in the pores at the fivefold axes of symmetry on AAV2 capsids with reduced packaging and reduced Rep-capsid interaction. Mutation of two threonines at the rim of the fivefold pore nearly completely abolished Rep-capsid interaction and packaging. This suggests a Rep-binding site at the highly conserved amino acids at or close to the pores formed by the capsid protein pentamers. A different mutant (P. Wu, W. Xiao, T. Conlon, J. Hughes, M. Agbandje-McKenna, T. Ferkol, T. Flotte, and N. Muzyczka, J. Virol. 74:8635-8647, 2000) with an amino acid exchange at the interface of capsid protein pentamers led to a complete block of DNA encapsidation. Analysis of the capsid conformation of this mutant revealed that the pores at the fivefold axes were occupied by VP1/VP2 N termini, thereby preventing DNA introduction into the capsid. Nevertheless, the corresponding capsids had more Rep proteins bound than wild-type AAV, showing that correct Rep interaction with the capsid depends on a defined capsid conformation. Both mutant types together support the conclusion that the pores at the fivefold symmetry axes are involved in genome packaging and that capsid conformation-dependent Rep-capsid interactions play an essential role in the packaging process.

    To establish a successful infection viruses need to overcome plant innate immune responses and redirect host gene expression for their multiplication and diffusion. Tomato yellow leaf curl Sardinia virus (TYLCSV) is a geminivirus, which causes significant economic losses in tomato. The multifunctional replication associated geminivirus protein (Rep) has an important role during viral infection. In particular, the Rep central domain spanning from aa 120 to 180 is known to interact with viral and host factors. In this study, we used long serial analysis of gene expression to analyse the transcriptional profiles of transgenic tomato plants expressing the first 210 amino acids of TYLCSV Rep (Rep210) and TYLCSV-infected wild-type tomato plants (Wt-Ty). Also, we compared these profiles with those of transgenic Rep130 tomatoes. Comparison of Wt-Ty and Rep210 libraries with the wild-type one identified 118 and 203 differentially expressed genes (DEGs), respectively. Importantly, 55% of Wt-Ty DEGs were in common with Rep210, and no ones showed opposite expression. Conversely, a negligible overlap was found between Rep130 DEGs and Wt-Ty and Rep210 ones. TYLCSV- and Rep210-repressed genes, but not induced ones, overlapped with the leaf senescence process. Interestingly, TYLCSV upregulates expression of genes involved in the negative regulation of programmed cell death (PCD), several of which were also regulated by the abscisic acid. Rep210 upregulated genes related to defence response, immune system processes and negative regulation of PCD. Collectively, our results support a model in which the Rep central domain has a pivotal role in redirecting host plant gene expression.

    Lightweight Autonomous Underwater Vehicles (AUVs) were developed for Naval Special Warfare (NSW) Group 4 search and survey missions from a commercial AUV baseline (Iver 2) through integration of commercial off-the-shelf (COTS) hardware components, and through software development for enhanced on-board Command and Control functions. The development period was 1 year under a project sponsored by the Office of Naval Research TechSolutions Program Office. Hardware integration was completed by the commercial AUV vendor, OceanServer Technology, Inc., and software development was conducted by the Naval Undersea Warfare Center, Naval Oceanographic Office, and U MASS Dartmouth, with support from hardware and software application providers (YSI, Inc., Imagenex Technology Corp., and CARIS). At the conclusion of the integration and development period, an at-sea performance evaluation was scheduled for the Lightweight NSW AUVs with NSWG-4 personnel. The venue for this evaluation was the NATO exercise Recognized Environmental Picture 10A (REP 10A), hosted by Marinha Portuguesa, and coordinated by the Faculdade de Engenharia-Universidade do Porto. REP 10A offered an opportunity to evaluate the performance of the new AUVs and to explore the Concept of Operations (CONOPS) for employing them in military survey operations in shallow coastal waters. Shore- and ship-launched scenarios with launch/recovery by a single operator in a one-to-many coordinated survey, on-scene data product generation and visualization, data push to Reach Back Cells for product integration and enhancement, and survey optimization to streamline survey effort and timelines were included in the CONOPS review. Opportunities to explore employment of hybrid AUV fleets in Combined Force scenarios were also utilized. The Naval Undersea Warfare Center, Marinha Portuguesa, the Faculdade de Engenharia-Universidade do Porto, and OceanServer Technology, Inc., were the primary participants bringing in-water resources to

    We prove the integrality of the Taylor coefficients of roots of mirror maps at the origin. By mirror maps, we mean formal power series z.exp(G(z)/F(z)), where F(z) and G(z)+log(z)F(z) are particular solutions of certain generalized hypergeometric differential equations. This enables us to prove a conjecture stated by Zhou in "Integrality properties of variations of Mahler measures" [arXiv:1006.2428v1 math.AG]. The proof of these results is an adaptation of the techniques used in our article "Crit\\`ere pour l'int\\'egralit\\'e des coefficients de Taylor des applications miroir", [J. Reine Angew. Math.

    We discuss the quantification of the local galaxy population and the impact of the ``New Era of Wide-Field Astronomy'' on this field, and, in particular, systematic errors in the measurement of the Luminosity Function. New results from the 2dFGRS are shown in which some of these selection effects have been removed. We introduce an INT-WFS project which will further reduce the selection biases. We show that there is a correlation between the surface brightness and the luminosity of galaxies and that new technologies are having a big impact on this field. Finally selection criteria from different surveys are modelled and it is shown that some of the major selection effects are surface brightness selection effects.

  15. GUT Model Discrimination by Nucleon Decay via Dim. 6 Effective Int.

    Science.gov (United States)

    Maekawa, Nobuhiuro; Muramatsu, Yu

    Anomalous U(1)A SUSY GUT models are attractive because they can solve most of difficulties in SUSY GUT models in a natural manner. One of the most important predictions of anomalous U(1)A SUSY GUT is that the nucleon decay via dim. 6 interactions are enhanced and the rough estimation gives τ(p→π0+e+)˜1034 years which is nothing but the present experimental lower bound, while nucleon decay via dim. 5 interactions are suppressed. We calculate dim. 6 effective int. and nucleon lifetimes for each decay mode in SU(5), SO(10) or E6 GUT models with various unitary matrices which diagonalize Yukawa matrices. In this calculation we use more than 50000 model points. One important observation is that the gauge group can be determined by measuring the branching ratios of nucleon. The detailed results will be given in our paper.1

Sin embargo el poder central no fue limitado en grado suficiente por la Constitución del 1991, como muestra el hecho de que el Ministro de Hacienda es el Presidente de la Junta Directiva del Banco de la República. Esto no sucede en ningun banco independiente del mundo por que los objetivos del gobierno son distintos a los del Banco Central y el Ministerio de Finanzas podría desviar al Banco de sus objetivos antiinflacionarios fundamentales. En Colombia, el gobierno no sólo participa en la Junta para acomodar sus múltiples objetivos sino también hace opocisión pública a la política monetaria y así la desacredita. El articulo plantea que el principio de no reelección hace que el horizonte de tiempo sea muy corto para que el gobierno coseche los frutos de una política de estabilización.

Four types of inequivalent (super)conformal actions are thus obtained. With the exclusion of the homogeneous parabolic case, dimensional constants are present. Both the inhomogeneity and the insertion of λ generalize the construction of Papadopoulos [CQG 30 (2013) 075018; arXiv:1210.1719]. Inhomogeneous D-module reps are presented for the d = 1 superconformal algebras osp(1∣2), sl(2∣1), B(1, 1) and A(1, 1). For centerless super Virasoro algebras D-module reps are presented (in the homogeneous case for N = 1; 2; 3; 4; in the inhomogeneous case for N = 1, 2, 3). The four types of d = 1 superconformal actions are derived for N = 1, 2, 4 systems. When N = 4, the homogeneously-induced actions are D(2, 1; α)-invariant (α is critically linked to λ); the inhomogeneously-induced actions are A(1, 1)-invariant. In d = 2, for a single bosonic field, the homogeneous transformations induce a conformally invariant power-law action, while the inhomogeneous transformations induce the conformally invariant Liouville action.

    Buchnera aphidicola is an obligate, strictly vertically transmitted, bacterial symbiont of aphids. It supplies its host with essential amino acids, nutrients required by aphids but deficient in their diet of plant phloem sap. Several lineages of Buchnera show adaptation to their nutritional role in the form of plasmid-mediated amplification of key-genes involved in the biosynthesis of tryptophan (trpEG) and leucine (leuABCD). Phylogenetic analyses of these plasmid-encoded functions have thus far suggested the absence of horizontal plasmid exchange among lineages of Buchnera. Here, we describe three new Buchnera plasmids, obtained from species of the aphid host families Lachnidae and Pemphigidae. All three plasmids belong to the repA1 family of Buchnera plasmids, which is characterized by the presence of a repA1-replicon responsible for replication initiation. A comprehensive analysis of this family of plasmids unexpectedly revealed significantly incongruent phylogenies for different plasmid and chromosomally encoded loci. We infer from these incongruencies a case of horizontal plasmid transfer in Buchnera. This process may have been mediated by secondary endosymbionts, which occasionally undergo horizontal transmission in aphids. PMID:10984505

    High-throughput omics datasets often contain technical replicates included to account for technical sources of noise in the measurement process. Although summarizing these replicate measurements by using robust averages may help to reduce the influence of noise on downstream data analysis, the information on the variance across the replicate measurements is lost in the averaging process and therefore typically disregarded in subsequent statistical analyses.We introduce RepExplore, a web-service dedicated to exploit the information captured in the technical replicate variance to provide more reliable and informative differential expression and abundance statistics for omics datasets. The software builds on previously published statistical methods, which have been applied successfully to biomedical omics data but are difficult to use without prior experience in programming or scripting. RepExplore facilitates the analysis by providing a fully automated data processing and interactive ranking tables, whisker plot, heat map and principal component analysis visualizations to interpret omics data and derived statistics.

    In this article, we will present a methodology to debug RGB-D SLAM systems as well as to generate testing data. We have created a model of a laboratory with an area of 250 m2 (25 × 10) with set of objects of different type. V-REP Microsoft Kinect sensor simulation model was used as a basis for robot vision system. Motion path of the sensor model has multiple loops. We have written a program in V-Rep native language Lua to record data array from the Microsoft Kinect sensor model. The array includes both RGB and Depth streams with full resolution (640 × 480) for every 10 cm of the path. The simulated path has absolute accuracy, since it is a simulation, and is represented by an array of transformation matrices (4 × 4). The length of the data array is 1000 steps or 100 m. The path simulates frequently occurring cases in SLAM, including loops. It is worth noting that the path was modeled for a mobile robot and it is represented by a 2D path parallel to the floor at a height of 40 cm.

    Single-stranded genomes of adeno-associated virus (AAV) are packaged into preformed capsids. It has been proposed that packaging is initiated by interaction of genome-bound Rep proteins to the capsid, thereby targeting the genome to the portal of encapsidation. Here we describe a panel of mutants with amino acid exchanges in the pores at the fivefold axes of symmetry on AAV2 capsids with reduced packaging and reduced Rep-capsid interaction. Mutation of two threonines at the rim of the fivefol...

  15. The tissue-specific Rep8/UBXD6 tethers p97 to the endoplasmic reticulum membrane for degradation of misfolded proteins.

    Directory of Open Access Journals (Sweden)

    Louise Madsen

    Full Text Available The protein known as p97 or VCP in mammals and Cdc48 in yeast is a versatile ATPase complex involved in several biological functions including membrane fusion, protein folding, and activation of membrane-bound transcription factors. In addition, p97 plays a central role in degradation of misfolded secretory proteins via the ER-associated degradation pathway. This functional diversity of p97 depends on its association with various cofactors, and to further our understanding of p97 function it is important that these cofactors are identified and analyzed. Here, we isolate and characterize the human protein named Rep8 or Ubxd6 as a new cofactor of p97. Mouse Rep8 is highly tissue-specific and abundant in gonads. In testes, Rep8 is expressed in post-meiotic round spermatids, whereas in ovaries Rep8 is expressed in granulosa cells. Rep8 associates directly with p97 via its UBX domain. We show that Rep8 is a transmembrane protein that localizes to the ER membrane with its UBX domain facing the cytoplasm. Knock-down of Rep8 expression in human cells leads to a decreased association of p97 with the ER membrane and concomitantly a retarded degradation of misfolded ER-derived proteasome substrates. Thus, Rep8 tethers p97 to the ER membrane for efficient ER-associated degradation.

    Mungbean yellow mosaic virus-Vigna (MYMV-Vig) is a bipartite geminivirus that causes a severe yellow mosaic disease in blackgram. An assay was developed to study MYMV-Vig replication by agroinoculation of tobacco leaf discs with partial dimers of the virus. This assay, in a non-host model plant, was used to evaluate pathogen-derived resistance contributed by MYMV-Vig genes in transgenic plants. Viral DNA accumulation was optimum in tobacco leaf discs cultured for 10 days after infection with Agrobacterium tumefaciens strain Ach5 containing partial dimers of both DNA A and DNA B of MYMV-Vig. Transgenic tobacco plants with MYMV-Vig genes for coat protein (CP), replication-associated protein (Rep)-sense, Rep-antisense, truncated Rep (T-Rep), nuclear shuttle protein (NSP) and movement protein (MP) were generated. Leaf discs from transgenic tobacco plants, harbouring MYMV-Vig genes, were agroinoculated with partial dimers of MYMV-Vig and analyzed for viral DNA accumulation. The leaf discs from transgenic tobacco plants harbouring CP and MP genes supported the accumulation of higher levels of MYMV-Vig DNA. However, MYMV-Vig accumulation was inhibited in one transgenic plant harbouring the Rep-sense gene and in two plants harbouring the T-Rep gene. Northern analysis of these plants revealed a good correlation between expression of Rep or T-Rep genes and inhibition of MYMV-Vig accumulation.

Desde la época de Gaspar Antonio Chi en 1580 hasta la desaparición de esta corte en la década de 1820, estos hombres mediaron directamente en disputas de propiedades, quejas contra las autoridades, y tradujeron decretos inicialmente publicados en español para la mayoría maya hablante de la provincia. Sus actividades demuestran que Yucatán poseyó un alto número de individuos que dominaron tanto el maya como el español hasta finales del periodo colonial. Además, la cantidad de individuos calificados sirviendo extra oficial mente como intérpretes durante finales del siglo dieciocho, y el sorprendente número de no-mayas que necesitaron sus servicios, muestran también que el periodo colonial fue una época en la que el maya se extendió como lenguaje predominante en Yucatán, en lugar de una época de declive para ese idioma.This paper focuses one type of important intermediaries of colonial Yucatan, the general interpreters of Yucatan's Juzgado Privado de Indios. From the time of Gaspar Antonio Chi in 1580 until the demise of this court in the 1820s, these men mediated directly in land disputes, complaints against priests and other officials, and translated decrees initially published in Spanish for the province's Maya-speaking majority. The activities of the interpreters demonstrate that Yucatan had a high number of individuals literate and fluent in both Maya and Spanish until the close of the colonial period. Furthermore, the quantity of qualified individuals serving unofficially as interpreters during the late eighteenth century and the surprising number of non-Mayas in need of their services also shows that the colonial period was a time in which Maya spread as the predominant language of Yucatan rather than a time of decline for the region's native language.

    2011-10-01

    Inserting genetic information at precise locations into the human genome has been the goal of gene transfer technology for almost two decades. The spectacular progress of mammalian genetics has led to the development of technology for genome editing and homologous recombination in human somatic cells that is finally approaching efficiency compatible with clinical application. Site-specific integration, or the insertion of genes at known locations by enzymes with target recognition capacity, has progressed slowly but steadily in recent years, and could very well be the basis of the next generation of gene transfer technology. This review focuses on the use of Rep, the replicase/integrase of the adeno-associated virus (AAV), to insert genes at the natural AAV integration site on human chromosome 19. This region (AAVS1) has characteristics that make it an ideal target for somatic transgenesis.

    The open-source release of self-replicating rapid prototypers (RepRaps) has created a rich opportunity for low-cost distributed digital fabrication of complex 3-D objects such as scientific equipment. For example, 3-D printable reactionware devices offer the opportunity to combine open hardware microfluidic handling with lab-on-a-chip reactionware to radically reduce costs and increase the number and complexity of microfluidic applications. To further drive down the cost while improving the performance of lab-on-a-chip paper-based microfluidic prototyping, this study reports on the development of a RepRap upgrade capable of converting a Prusa Mendel RepRap into a wax 3-D printer for paper-based microfluidic applications. An open-source hardware approach is used to demonstrate a 3-D printable upgrade for the 3-D printer, which combines a heated syringe pump with the RepRap/Arduino 3-D control. The bill of materials, designs, basic assembly, and use instructions are provided, along with a completely free and open-source software tool chain. The open-source hardware device described here accelerates the potential of the nascent field of electrochemical detection combined with paper-based microfluidics by dropping the marginal cost of prototyping to nearly zero while accelerating the turnover between paper-based microfluidic designs. © 2016 Society for Laboratory Automation and Screening.

    Full Text Available In the present study, Randomly Amplified Polymorphic DNA‌ (RAPD and Repetitive Extragenic Palindromic sequence-based Polymerase Chain Reaction (REP-PCR were used to characterize 131 isolates of Pasteurella multocida, originating from different healthy and diseased animal species obtained from several geographical regions of Iran. The RAPD and REP-PCR generated amplified products in the range of 300 to 3400 bp and 200 to 2850 bp, respectively. Among all of the P. multocida isolates, cluster analysis revealed that 63 clusters and nine untypable isolates and 81 clusters and six untypable isolates were produced with RAPD and REP-PCR methods, respectively. The results indicated that the REP-PCR method showed a slightly higher level of discrimination power in differentiating of P. multocida isolates as compared with RAPD. The results showed that a considerable level of genetic diversity exists among P. multocida isolates even in the isolates with the same animal or geographical origins. There was no host- and region-specific pattern. In addition, the isolates obtained from the healthy and diseased animal did not reveal any correlation genotypic profiles, which could be supported by the hypothesis that P. multocida is a strictly opportunistic pathogen. In conclusion, because of a large amount of genetic heterogeneityin the P. multocida isolates, Pasteurellosis may be caused by different clones in the same herd or animal.

    The Gene Ontology (GO) has been used in high-throughput omics research as a major bioinformatics resource. The hierarchical structure of GO provides users a convenient platform for biological information abstraction and hypothesis testing. Computational methods have been developed to identify functionally similar genes. However, none of the existing measurements take into account all the rich information in GO. Similarly, using these existing methods, web-based applications have been constructed to compute gene functional similarities, and to provide pure text-based outputs. Without a graphical visualization interface, it is difficult for result interpretation. We present InteGO2, a web tool that allows researchers to calculate the GO-based gene semantic similarities using seven widely used GO-based similarity measurements. Also, we provide an integrative measurement that synergistically integrates all the individual measurements to improve the overall performance. Using HTML5 and cytoscape.js, we provide a graphical interface in InteGO2 to visualize the resulting gene functional association networks. InteGO2 is an easy-to-use HTML5 based web tool. With it, researchers can measure gene or gene product functional similarity conveniently, and visualize the network of functional interactions in a graphical interface.

    Over the last decade, communication industries have witnessed a tremendous expansion, while, the biological effects of electromagnetic waves have not been fully elucidated. Current study aimed at evaluating the mutagenic effect of long-term exposure to 900-MHz radiation on alpha-Int1 gene sequences of Candida albicans. A standard 900 MHz radiation generator was used for radiation. 10 ml volumes from a stock suspension of C. albicans were transferred into 10 polystyrene tubes. Five tubes were exposed at 4 °C to a fixed magnitude of radiation with different time periods of 10, 70, 210, 350 and 490 h. The other 5 tubes were kept far enough from radiation. The samples underwent genomic DNA extraction. PCR amplification of alpha-Int1 gene sequence was done using one set of primers. PCR products were resolved using agarose gel electrophoresis and the nucleotide sequences were determined. All samples showed a clear electrophoretic band around 441 bp and further sequencing revealed the amplified DNA segments are related to alpha-Int1 gene of the yeast. No mutations in the gene were seen in radiation exposed samples. Long-term exposure of the yeast to mobile phone radiation under the above mentioned conditions had no mutagenic effect on alpha-Int1 gene sequence.

    CTnDOT encodes an integrase that is a member of the tyrosine recombinase family. The recombination reaction proceeds by sequential sets of genetic exchanges between the attDOT site in CTnDOT and an attB site in the chromosome. The exchanges are separated by 7 base pairs in each site. Unlike most tyrosine recombinases, IntDOT exchanges sites that contain different DNA sequences between the exchange sites to generate Holliday junctions (HJs) that contain mismatched bases. We demonstrate that IntDOT resolves synthetic HJs in vitro. Holliday junctions that contain identical sequences between the exchange sites are resolved into both substrates and products, while HJs that contain mismatches are resolved only to substrates. This result implies that resolution of HJs to products requires the formation of a higher-order nucleoprotein complex with natural sites containing IntDOT. We also found that proteins with substitutions of residues (V95, K94, and K96) in a putative alpha helix at the junction of the N and CB domains (coupler region) were defective in resolving HJs. Mutational analysis of charged residues in the coupler and the N terminus of the protein did not provide evidence for a charge interaction between the regions of the protein. V95 may participate in a hydrophobic interaction with another region of IntDOT. PMID:21216992

    Full Text Available The yeast translation termination factor Sup35p, by aggregating as the [PSI+] prion, enables ribosomes to read-through stop codons, thus expanding the diversity of the Saccharomyces cerevisiae proteome. Yeast prions are functional amyloids that replicate by templating their conformation on native protein molecules, then assembling as large aggregates and fibers. Prions propagate epigenetically from mother to daughter cells by fragmentation of such assemblies. In the N-terminal prion-forming domain, Sup35p has glutamine/asparagine-rich oligopeptide repeats (OPRs, which enable propagation through chaperone-elicited shearing. We have engineered chimeras by replacing the polar OPRs in Sup35p by up to five repeats of a hydrophobic amyloidogenic sequence from the synthetic bacterial prionoid RepA-WH1. The resulting hybrid, [REP-PSI+], i was functional in a stop codon read-through assay in S. cerevisiae; ii generates weak phenotypic variants upon both its expression or transformation into [psi-] cells; iii these variants correlated with high molecular weight aggregates resistant to SDS during electrophoresis; and iv according to fluorescence microscopy, the fusion of the prion domains from the engineered chimeras to the reporter protein mCherry generated perivacuolar aggregate foci in yeast cells. All these are signatures of bona fide yeast prions. As assessed through biophysical approaches, the chimeras assembled as oligomers rather than as the fibers characteristic of [PSI+]. These results suggest that it is the balance between polar and hydrophobic residues in OPRs what determines prion conformational dynamics. In addition, our findings illustrate the feasibility of enabling new propagation traits in yeast prions by engineering OPRs with heterologous amyloidogenic sequence repeats.

The opposition felt alternation via elections would be difficult to achieve so resorted to violent and unconstitutional practices to reach government. The Portuguese political parties modernised themselves in this period, but failed to turn into mass parties. In major cities they acted as a cadre party and in the rural area as a party of notables. The First Republic failed to take solid steps to democratise the political system were And Portugal remained tied to the liberal and elitist tradition of the nineteenth century, although in a republican version.El Partido Republicano Portugués se convirtió en el partido dominante del sistema político de la Primera República Portuguesa (1910-1926 debido a causas históricas, organizacionales, clientelistas, violentas y constitucionales.

Los partidos políticos portugueses se modernizaron en este período, pero no se convirtieron en partidos de masas. En las principales ciudades actuaban como partidos de cuadros y en las zonas rurales como partidos de notables. Durante la Primera República no se dieron pasos consistentes para democratizar el sistema político.

    Full Text Available Dans les cours au Collège de France réunis dans Naissance de la biopolitique, Foucault soutient qu’une science économico-juridique est rigoureusement impossible. Or cette thèse radicale mérite discussion, à partir d’un auteur trop souvent ignoré des historiens de la genèse de l’économie politique. Montesquieu, à sa façon, contribue à la constitution de ce savoir économico-juridique, susceptible de penser ensemble sujet d’intérêt et sujet de droit. L’esprit de cette étude ne sera pas de critiquer Foucault en montrant que Montesquieu ne « rentre » pas dans l’opposition de ses paradigmes, mais plutôt de tenter de mesurer l’originalité d’une pensée qui conçoit des échanges entre propriété et liberté qui ont pour effet d’unifier rationalité économique et rationalité juridique.

    Adeno-associated virus (AAV) has previously been shown to inhibit the replication of its helper virus herpes simplex virus type 1 (HSV-1), and the inhibitory activity has been attributed to the expression of the AAV Rep proteins. In the present study, we assessed the Rep activities required for inhibition of HSV-1 replication using a panel of wild-type and mutant Rep proteins lacking defined domains and activities. We found that the inhibition of HSV-1 replication required Rep DNA-binding and ATPase/helicase activities but not endonuclease activity. The Rep activities required for inhibition of HSV-1 replication precisely coincided with the activities that were responsible for induction of cellular DNA damage and apoptosis, suggesting that these three processes are closely linked. Notably, the presence of Rep induced the hyperphosphorylation of a DNA damage marker, replication protein A (RPA), which has been reported not to be normally hyperphosphorylated during HSV-1 infection and to be sequestered away from HSV-1 replication compartments during infection. Finally, we demonstrate that the execution of apoptosis is not required for inhibition of HSV-1 replication and that the hyperphosphorylation of RPA per se is not inhibitory for HSV-1 replication, suggesting that these two processes are not directly responsible for the inhibition of HSV-1 replication by Rep.

    Lenalidomide (Revlimid®) combined with intermittent dexamethasone (the RD regimen) is one of the current standards for treatment of patients with relapsed/refractory multiple myeloma (MM). However, since the disease in the majority of patients will become resistant to RD, or treatment with RD needs to be discontinued due to side effects, we evaluated the combination lenalidomide, low-dose oral cyclophosphamide, with prednisone (REP) in patients with relapsed/refractory MM previously exposed to RD. For this purpose, we performed a single centre retrospective study of the efficacy of REP in 19 patients with relapsed/refractory MM. Overall response rate (partial response or better) with REP was 68% compared with 83% with RD, but with a shorter time to response with the triplet REP. Time to progression after REP was 6 months. Overall the REP regimen was better tolerated compared to RD. We conclude that the REP regimen is an effective treatment regimen for patients with relapsed/refractory MM with good tolerance, warranting further exploration in prospective randomized trials.

Is it possible? On this journey across all of written culture that Saavedra describes, where the inhabitants of the city are authors of ‘literary’ texts and the arts live together with the sciences and the muses, the author analyses with subtle irony the present and the tradition of everything that surrounds the production of all that is written. With the classic resource of the ‘Dream’ he shows an incredibly clear panorama where we can recognize the beginnings of capitalism, in which books have gone from being considered repositories of wisdom and common sense, to becoming mere marketplace objects.El autor de la República Literaria, un diplomático viajero del siglo XVII, sueña una ciudad de papel: leer una ciudad como si fuera un libro y leer un libro como si fuera un viaje a través de la historia literaria. ¿Es posible?

Con el clásico recurso del «Sueño» muestra un panorama increíblemente nítido donde podemos reconocer los inicios del capitalismo en el que los libros han pasado de ser considerados como un depósito de sabiduría y cordura a tener carácter de mero objeto de mercado.

  13. Exon sequence requirements for excision in vivo of the bacterial group II intron RmInt1

    2011-05-01

    Full Text Available Abstract Background Group II intron splicing proceeds through two sequential transesterification reactions in which the 5' and 3'-exons are joined together and the lariat intron is released. The intron-encoded protein (IEP assists the splicing of the intron in vivo and remains bound to the excised intron lariat RNA in a ribonucleoprotein particle (RNP that promotes intron mobility. Exon recognition occurs through base-pairing interactions between two guide sequences on the ribozyme domain dI known as EBS1 and EBS2 and two stretches of sequence known as IBS1 and IBS2 on the 5' exon, whereas the 3' exon is recognized through interaction with the sequence immediately upstream from EBS1 [(δ-δ' interaction (subgroup IIA] or with a nucleotide [(EBS3-IBS3 interaction (subgroup IIB and IIC] located in the coordination-loop of dI. The δ nucleotide is involved in base pairing with another intron residue (δ' in subgroup IIB introns and this interaction facilitates base pairing between the 5' exon and the intron. Results In this study, we investigated nucleotide requirements in the distal 5'- and 3' exon regions, EBS-IBS interactions and δ-δ' pairing for excision of the group IIB intron RmInt1 in vivo. We found that the EBS1-IBS1 interaction was required and sufficient for RmInt1 excision. In addition, we provide evidence for the occurrence of canonical δ-δ' pairing and its importance for the intron excision in vivo. Conclusions The excision in vivo of the RmInt1 intron is a favored process, with very few constraints for sequence recognition in both the 5' and 3'-exons. Our results contribute to understand how group II introns spread in nature, and might facilitate the use of RmInt1 in gene targeting.

    Aerobic composting is usually employed to treat livestock manure. In this study, a bio-surfactant (rhamnolipid, RL) and chemical surfactant (Tween 80, Tw) were added to chicken manure during composting and their effects were determined on the variations in ARGs and intI1. After composting, the reductions in the RAs of ARGs and intI1 with the addition of Tw (1-4.7logs) were generally greater than that with the addition of RL (0.8-3.7logs) and the control (CK) (0.3-2.6logs), and the enrichment of ARGs was higher with CK (0.9-1.8logs). The ARG profiles were affected significantly by temperature and the water-soluble carbon contents. RL and Tw effectively reduced the concentrations of bio-available Cu and Zn, thereby hindering the co-selection of ARGs by heavy metals. The effects of RL and Tw on ARGs and intI1 indicate that the addition of Tw was slightly more effective than RL after composting.

    Full Text Available Este artículo examina un aspecto seminal, pero sorprendente en la crítica de Platón de la poesía: Platón destierra a los contenidos, no sólo particular, y los autores, pero las formas poéticas también ellas mismas, en concreto la forma mimética. El análisis muestra que la principal razón para desterrar tales reside en el hecho de que Platón descubrió que la forma como la forma (con independencia de su contenido tiene un carácter autónomo y se rige por criterios estéticos y no moral. Estos criterios estéticos son incompatibles con la ideología que apoya la polis ideal. Esto pone de relieve el mérito del análisis de Platón de que no está en la evaluación de la actividad poética, sino en la identificación de las puramente estéticas y sus consecuencias sobre el programa político de la República

For that, I worked with a series of cartoons published in newspapers and magazines in the span of time between 1954 and 1930, matching the intertextuality of these images with some of the satiric and ironic speeches produced by witnesses. It is demonstrated there is likeness between the comic inversion and the textuality of the memory, when they invent concerning their time and other ones, the verisimilitude of the images.

Neste contexto, as manifestações da loucura passaram a ser associadas à doença, à degeneração e ao risco e sofreram variadas medidas de opressão justificadas "cientificamente". Até hoje, as interpretações científicas do problema da "doença mental" continuam localizando a enfermidade no paciente. Ao reduzir a doença e a sua causa a uma problemática exclusivamente pessoal, sem que se considere o contexto socioeconômico e político da sua emergência, estas explicações configuram-se como ideologia.

La primera, partidària del model de llengua de l’IEC, era minoritària als anys vint però es generalitza a partir dels anys trenta (La Veu de Tortosa, La Veu Comarcal, Ara, Acció, Vida Tortosina i Lluita; mentre que el tortosinisme, que es correspon amb una ideologia cada cop més localista i que eleva el «parlar tortosí» a la categoria de llengua, queda reduït durant la II República a tres revistes bilingües: La Zuda, Germanor i La Santa Cinta. There were two linguistic actitudes in the tortosine press of the first third in the 20th century: the fabriana amb the tortosinista. The fabriana, in favour of the IEC linguistic model, was in minority during the 20’s, but it became widespread from the 30’s (La Veu de Tortosa, La Veu Comarcal, Ara, Acció, Vida Tortosina i Lluita. The second, the tortosinista, had a local ideology and compared the tortosinisme talk as a complet language, but it was reduced during the ii Republic to three magazines: La Zuda, Germanor i La Santa Cinta.

    Repeated dose toxicity studies from the RepDose database (DB) were used to determine interspecies differences for rats and mice. NOEL (no observed effect level) ratios based on systemic effects were investigated for three different types of exposure: inhalation, oral food/drinking water and oral gavage. Furthermore, NOEL ratios for local effects in inhalation studies were evaluated. On the basis of the NOEL ratio distributions, interspecies assessment factors (AF) are evaluated. All data sets were best described by a lognormal distribution. No difference was seen between inhalation and oral exposure for systemic effects. Rats and mice were on average equally sensitive at equipotent doses with geometric mean (GM) values of 1 and geometric standard deviation (GSD) values ranging from 2.30 to 3.08. The local AF based on inhalation exposure resulted in a similar distribution with GM values of 1 and GSD values between 2.53 and 2.70. Our analysis confirms former analyses on interspecies differences, including also dog and human data. Furthermore it supports the principle of allometric scaling according to caloric demand in the case that body doses are applied. In conclusion, an interspecies distribution animal/human with a GM equal to allometric scaling and a GSD of 2.5 was derived.

    The structure-function correlation of membrane proteins have been a difficult task, particularly in context to transient protein complexes. The molecular simulation of ternary complex of Rab7::REP1::GGTase-II was carried out to understand the basic structural events occurring during the prenylation event of Rab proteins, using the software YASARA. The study suggested that the C-terminus of Rab7 has to be in completely extended conformation during prenylation to reach the active site of RabGGTase-II. Also, attempt was made to find putative drug binding sites on the ternary complex of Rab7::REP1::GGTase-II using Q-SiteFinder programme. The comprehensive consensus probe generated by the program revealed a total of 10 major pockets as putative drug binding sites on Rab7::REP:: GGTase-II ternary complex. These pockets were found on REP protein and GGTase protein subunits. The Rab7 was found to be devoid of any putative drug binding sites in the ternary complex. The phylogenetic analysis of 60 Rab proteins of human was carried out using PHYLIP and study indicated the close phylogenetic relationship between Rab7 and Rab9 proteins of human and hence with further in silico study, the present observations can be extrapolated to Rab9 proteins. The study paves a good platform for further experimental verifications of the findings and other in silico studies like identifying the potential drug targets by searching the putative drug binding sites, generating pharmacophoric pattern, searching or constructing suitable ligand and docking studies.

  17. Overview of the relativistic electron precipitations (REP) observed on LEO satellites and ISS by Bulgarian build instruments

    Science.gov (United States)

    Dachev, Tsvetan

    Relativistic electron precipitation (REP) are observed by the R3D B2/B3 and RD3-B3 instruments during the flights of the Foton M2/M3 and “BION-M” № 1 satellite in 2005, 2007 and 2013, and by the R3DE/R instruments at the EXPOSE-E facility of the European Columbus module and at the EXPOSE-R facility of the Russian Zvezda module of the International Space Station (ISS) in the period from February 2008 till August 2010. The obtained dose rates strongly depend by the external and internal shielding of the detectors in the instruments. The highest dose rate reaching more than 20 mGy h (-1) was observed outside the ISS Zvezda module during the REP in April 2010 being the second largest in GOES history with a >2 MeV electron fluence event. REP doses behind relatively thick shielding are too small but may play considerable role during extra vehicular activity (EVA) when the cosmonauts/astronauts body is shielded only by the space suit.

    Yellow mosaic disease causes severe yield loss in grain legumes in Indian subcontinent and south east Asia. The disease is caused by two virus species, Mungbean yellow mosaic India virus (MYMIV) and Mungbean yellow mosaic virus (MYMV). They have genome organization typical of Old World begomoviruses, the unique feature being the presence of an open reading frame (ORF) AV2 upstream of coat protein gene. In order to elucidate its function, ORF AV2 of blackgram isolate, Mungbean yellow mosaic India virus-[India:New Delhi:Blackgram 3:1991] MYMIV-[IN:ND:Bg3:91] and cowpea isolate, Mungbean yellow mosaic India virus-[India:New Delhi:Cowpea7:1998] MYMIV-[IN:ND:Cp7:98], respectively, were over expressed in Escherichia coli in fusion with maltose binding protein (MBP). The recombinant protein did not show efficient binding to DNA. However, both MBP-BgAV2 and MBP-CpAV2 proteins modulated nicking and ATPase activity of replication initiation protein (Rep). Even low concentration, 20 ng of MBP-BgAV2 and MBP-CpAV2 could bring 20 folds increase in nicking activity of Rep. Similarly in the presence of AV2 protein, two to three fold increase in ATPase activity was observed. It is hypothesized that AV2 protein may play a role of accessory protein modulating Rep activities.

En este sentido estamos de acuerdo con quienes afirman que el estallido de la guerra del 36 es el resultado de un proceso que arranca del mismo año en que se proclama la II República, iniciándose ya entonces —como sostiene Andrés M.

La educación republicana en tiempo de guerra no puede quedar fuera de esta consideración, porque aquélla sumerge sus cimientos más profundos en la política educativa de 1931-35. Efectivamente, muchas de las acciones educativas y culturales llevadas a cabo durante la guerra no tendrían fácil explicación si no se examina previamente la tarea de la República del 31 en estos mismos aspectos.

    Geminiviruses, single-stranded DNA plant viruses, encode a replication-initiator protein (Rep) that is indispensable for virus replication. A potential cyclin interaction motif (RXL) in the sequence of African cassava mosaic virus Rep may be an alternative link to cell cycle controls to the known interaction with plant homologs of retinoblastoma protein (pRBR). Mutation of this motif abrogated rereplication in fission yeast induced by expression of wildtype Rep suggesting that Rep interacts via its RXL motif with one or several yeast proteins. The RXL motif is essential for viral infection of Nicotiana benthamiana plants, since mutation of this motif in infectious clones prevented any symptomatic infection. The cell-cycle link (Clink) protein of a nanovirus (faba bean necrotic yellows virus) was investigated that activates the cell cycle by binding via its LXCXE motif to pRBR. Expression of wildtype Clink and a Clink mutant deficient in pRBR-binding did not trigger rereplication in fission yeast. - Highlights: • A potential cyclin interaction motif is conserved in geminivirus Rep proteins. • In ACMV Rep, this motif (RXL) is essential for rereplication of fission yeast DNA. • Mutating RXL abrogated viral infection completely in Nicotiana benthamiana. • Expression of a nanovirus Clink protein in yeast did not induce rereplication. • Plant viruses may have evolved multiple routes to exploit host DNA synthesis.

    Full Text Available Platão não é o iniciador, e sim o herdeiro da "velha divergência" entre filósofos e poetas. A motivação ético-teológica, que já animava Xenófanes,vai se reatualizar na República. Para poder apreciar o sentido dessa reatualização, importa que não se considere o Livro X isoladamente, mas se atente para os primeiros livros do diálogo. Neles, e com vistas a uma melhor determinação do justo -que é o que está em pauta-, Platão mostra a necessidade de se discutir as afirmações dos poetas. Trata-se assim de destituí-los da autoridade de que ainda gozam na educação e na opinião comum. Só graças à discussão filosófica e a uma educação por ela inspirada -o que pressupõe a produção ou a seleção de mitos- é que se pode esperar uma maior realização da justiça, tanto no plano do indivíduo (do governo de sua alma quanto no nível da cidade. A leitura aqui proposta das "razões" de Platão na República não impede que reconheçamos a importância da tragédia para a compreensão da existência humana, inclusive no que toca à idéia do divino.Plato is not the initiator, but rather the heir of the "old quarrel", between philosophers and poets. The ethical and theological motivation that drove Xenophanes is brought to date in the Republic. In order to realize that, one must take into account the whole of the dialogue - where the definition of justice is at stake - and, more precisely, its first books. There, Plato shows how important it is to put the poets' claims to question. The point is, after all, to deprive them of the authority they enjoy in what concerns educational matters as well as with public opinion. It is only through an education which is inspired by philosophical questioning - which also implies the production and selection of myths - that one can expect more justice both on the individual (the gouvernment of his soul and on the city levels. The reading we propose of Plato's "reasons" in the Republic does

En este punto, Platón es quizás el más estudiado, siempre sus diálogos resultan útiles para quien recorre sus páginas, ya convertidas en verdaderos monumentos de la filosofía, con pasajes y afirmaciones hasta hoy irrefutables, además haciendo de su maestro Sócrates un personaje invalorable para la sabiduría universal. La innata ansia por una vida mejor, empuja al hombre casi siempre a la búsqueda de un mundo sin defectos. Esta es la razón de sus ilusiones utópicas de alcanzar justica, entendida ella como la perfecta armonía en la convivencia social. De la producción platónica, extensa, variada y valiosa, por todo lo que trata y por su sobrevivencia al paso de los años, la obra La República ocupa un lugar de preferencia, por eso estudiar sus paginas y repasar, tanto como re-pensar sus conceptos, es buen estimulo para quienes desean conocer temas de trascendencia en Filosofía, Derecho o afines. Volver a los clásicos es siempre un deber, ellos siempre son fascinantes y sus enseñanzas perduran con gran lozanía, a prueba de todo elemento corrosivo, por tanto no hay pretexto que valga, como para no estudiar, lo que sobre la justicia con genialidad nos comentaron hace ya tantos años.

  5. High burnup effects on fuel behaviour under accident conditions: the tests CABRI REP-Na

    Science.gov (United States)

    Schmitz, Franz; Papin, Joelle

    A large, performance based, knowledge and experience in the field of nuclear fuel behaviour is available for nominal operation conditions. The database is continuously completed and precursor assembly irradiations are performed for testing of new materials and innovative designs. This procedure produces data and arguments to extend licencing limits in the permanent research for economic competitiveness. A similar effort must be devoted to the establishment of a database for fuel behaviour under off-normal and accident conditions. In particular, special attention must be given to the so-called design-basis-accident (DBA) conditions. Safety criteria are formulated for these situations and must be respected without consideration of the occurrence probability and the risk associated to the accident situation. The introduction of MOX fuel into the cores of light water reactors and the steadily increasing goal burnup of the fuel call for research work, both experimental and analytical, in the field of fuel response to DBA conditions. In 1992, a significant programme step, CABRI REP-Na, has been launched by the French Nuclear Safety and Protection Institute (IPSN) in the field of the reactivity initiated accident (RIA). After performing the nine experiments of the initial test matrix it can be concluded that important new findings have been evidenced. High burnup clad corrosion and the associated degradation of the mechanical properties of the ZIRCALOY4 clad is one of the key phenomena of the fuel behaviour under accident conditions. Equally important is the evidence that transient, dynamic fission gas effects resulting from the close to adiabatic heating introduces a new explosive loading mechanism which may lead to clad rupture under RIA conditions, especially in the case of heterogeneous MOX fuel.

Une création, même si elle se place sous le sceau du réalisme, a un rapport très fort mais indirect avec le contexte historique de sa genèse. Elle est le produit de la rencontre d’un contexte, d’un créateur doté d’une idéologie, d’un « habitus », d’un corpus de valeurs, des modes et techniques en vigueur dans le champ de la création au moment de celle-ci et, comme le rappelle Bourdieu, de la stratégie du créateur par rapport à ses collègues/concurrents. Enfin, sans ajouter une note discordante supplémentaire aux théories de la réception, l’œuvre sera perçue de façon différente selon les publics. My Son the Fanatic sera donc perçu comme une œuvre satanique par les fondamentalistes musulmans, mais sans doute aussi chrétiens, comme une bluette charmante par les midinettes au grand cœur qui semblent être le public visé par la présentation publicitaire du film, comme une démonstration de la justesse de leurs thèses par les partisans de l’intégration, mais aussi par les émules de Huntington pour qui le choc des civilisations est inéluctable, enfin comme une manifestation irresponsable d’ « islamophobie » par les nostalgiques des politiques multiculturalistes d’antan.

    The ESO/MPG WFI and the INT WFC wide field archives comprising 330 000 images were mined to search for serendipitous encounters of known Near Earth Asteroids (NEAs) and Potentially Hazardous Asteroids (PHAs). A total of 152 asteroids (44 PHAs and 108 other NEAs) were identified using the PRECOVERY software, their astrometry being measured on 761 images and sent to the Minor Planet Centre. Both recoveries and precoveries were reported, including prolonged orbital arcs for 18 precovered objects and 10 recoveries. We analyze all new opposition data by comparing the orbits fitted before and after including our contributions. We conclude the paper presenting "Mega-Precovery", a new online service focused on data mining of many instrument archives simultaneously for one or a few given asteroids. A total of 28 instrument archives have been made available for mining using this tool, adding together about 2.5 million images forming the "Mega-Archive".

    The INT/WFC Photometric H-Alpha Survey of the Northern Galactic Plane (IPHAS) is a 1800 square degrees imaging survey covering Galactic latitudes |b| < 5 deg and longitudes l = 30 to 215 deg in the r, i and H\\alpha\\ filters using the Wide Field Camera (WFC) on the 2.5-metre Isaac Newton Telescope (INT) in La Palma. We present the first quality-controlled and globally-calibrated source catalogue derived from the survey, providing single-epoch photometry for 219 million unique sources across 92% of the footprint. The observations were carried out between 2003 and 2012 at a median seeing of 1.1 arcsec (sampled at 0.33 arcsec/pixel) and to a mean 5\\sigma-depth of 21.2 (r), 20.0 (i) and 20.3 (H\\alpha) in the Vega magnitude system. We explain the data reduction and quality control procedures, describe and test the global re-calibration, and detail the construction of the new catalogue. We show that the new calibration is accurate to 0.03 mag (rms) and recommend a series of quality criteria to select the most rel...

    The INT/WFC Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS) is an imaging survey being carried out in H-alpha, r' and i' filters, with the Wide Field Camera (WFC) on the 2.5-metre Isaac Newton Telescope (INT) to a depth of r'=20 (10 sigma). The survey is aimed at revealing large scale structure in our local galaxy, and also the properties of key early and late populations making up the Milky Way. Mapping emission line objects enables a particular focus on objects in the young and old stages of stellar evolution ranging from early T-Tauri stars to late planetary nebulae. In this paper we present the IPHAS Initial Data Release, primarily a photometric catalogue of about 200 million unique objects, coupled with associated image data covering about 1600 square degrees in three passbands. We note how access to the primary data products has been implemented through use of standard virtual observatory publishing interfaces. Simple traditional web access is provided to the main IPHAS photometric cat...

El programa político del PAE aceptaba la República —a diferencia de otros partidos derechistas del momento, como la CEDA y los monárquicos— y defendía la unidad nacional, el establecimiento de una segunda Cámara legislativa, la protección de la agricultura y la industria mediante aranceles, el libre comercio dentro de las fronteras nacionales y la revisión de algunas leyes del primer bienio como la Reforma Agraria de 1932. El objetivo era la configuración de una República conservadora distinta, en aspectos fundamentales, a la diseñada por la Constitución de 1931 y la legislación del bienio social-republicano.The Spanish Agrarian Party (Partido Agrario Español, PAE, founded in january of 1934 and presided by José Martínez de Velasco, was, in the political life of the Spanish Second Republic, a conservative and republican option. The agrarian program accepted the republican regime —in opposition to other conservative parties, like the CEDA or the monarchists— and defended the national union, the establishment of a Senate, the protection of the national agriculture and industry trough tariffs, the free trade in the Spanish market and the revision of some laws voted in the first biennium like the Agrarian Reform, promulgated in 1932. The idea was to establish a conservative Republic, different, in some fundamental aspects, of the regime designed by the Constitution of 1931 and the legislation approved during the socialist-republican biennium.

    Full Text Available Santo Domingo, the capital of the Dominican Republic, has not escaped the phenomenon of urban growth and the concentration of large slum areas or hovels, mainly due to the migratory movements of the peasants who have been driven from the country. As a viable solution to the enormous problem of housing in this city, INVI, with the participation of the World Bank, is putting forward projects for lots supplied with services in which infrastructure services are installed on urban land and plots or parcels of land are given to families so that they can build or complete their houses. These projects are located in places registering a greater tendency towards development. The urban plan formulated in both projects is of an eminently pedestrian nature with a reduced thoroughfare for vehicles. In the pedestrian precinct, it was possible to lay down what have been called mini-parks, which involve widening the pedestrian thoroughfare and, in addition to constituting green areas distributed throughout the projects, they also reinforce the idea of a neighbourhood. Because of the scope of the projects, a series of installations have been provided to maintain their own community services, as well as commercial and institutional ones, which are distributed strategically.Santo Domingo, capital de la República Dominicana, no ha escapado al fenómeno del crecimiento urbano y a la concentración de grandes tugurios o arrabales, debido principalmente a los movimientos migratorios de los campesinos expulsados del campo.

Alguns acreditam que os temas matemáticos empregados nos diálogos são fantasias matemáticas, outros defendem baseados, sobretudo no testemunho de Aristóteles, que Platão teria substituído na sua hipótese as formas inteligíveis pelos números ideais. Sem tomar partido de antemão nestas querelas, o que propomos aqui é uma investigação acerca da natureza dos números fundamentada exclusivamente nos textos de Platão, particularmente orientada por uma passagem do livro VII do diálogo República(525 b11- c3, em que Sócrates diz o seguinte: "Seria, portanto, conveniente colocar este estudo, ò Glaucon, dentro de uma legislação e persuadir aqueles que vão participar das grandes coisas na cidade a irem ao cálculo e a aplicarem-se a ele, não nos seus afazeres privados, mas até chegarem à contemplação da natureza dos números através da própria intelecção (...".The presence of the mathematics in Plato's dialogues is unquestionable.

    Full Text Available The Partido Galeguista (PG was created in December 1931 as the expression of Galician nationalism during the Second Republic (1931-1936. Prior to that, the Galician nationalists had been very influential in the cultural sphere but rather powerless from a political point of view. The PG regarded agriculture and peasantry as a priority, not only because of their objective importance in the Galician economy and society in the 1930s but also because they were seen as the bulwarks of the national identity. In fact, the characteristics, needs and paths of development of the Galician agrarian sector were usually defined as opposed to those of the rest of Spain. It is then understable that the PG tried to win the agrarian unions over, and that it is arguable that it had plenty of common features with the so-called Agrarian Parties in other European regions.

    O Partido Galeguista (PG foi creado en decembro de 1931 como expresión do nacionalismo galego durante a Segunda República (1931-1936. Con anterioridade, os nacionalistas galegos foron moi influíntes no eido cultural pero maiormente inoperantes dende o punto de vista político. O PG consideraba a agricultura e o campesiñado como unha prioridade, non só pola súa importancia obxectiva na economía e sociedade galegas dos anos trinta senón tamén porque eran vistos como os baluartes da identidade nacional. De feito, as características, necesidades e vías de desenvolvemento do sector agrario galego eran normalmente definidas en oposición ás do resto de España. É daquela comprensible que o PG tentase gañarse ás sociedades agrarias, e mesmo se pode afirmar que tiña moitos puntos en común cos chamados Partidos Agrarios doutras rexións europeas.

The raw meat paste samples before heat treatment were tested positively for the presence of three staphylococci species: Staphylococcus aureus, Staphylococcus haemolyticus and Staphylococcus epidermidis. Subsequent microbial analysis of meat paste components and ingredients (fresh meat, water, spices, equipment identified only the spices used as positive for S. aureus (coriander, cinnamon, badian, mustard – (10 - 40 cfu/g and S. haemolyticus strains (juniper, ginger. The collection of sixteen collected strains (S. aureus (n = 4, S. haemolyticus (n = 4, S. epidermidis (n = 8 has been typed with the rep-PCR method utilising (GTG5 primer. Analysis of the fingerprints using the unweighted pair-group method using arithmetic averages (UPGMA clustering method revealed presence of eleven strain clusters with similarity lower than 90%: two fingerprint clusters of S. aureus, three individual clusters characteristic for S. haemolyticus and six different S. epidermidis specific clusters. The S. aureus strains from different types of spice were identical, resp. very similar. Molecular tracking composed from the rep-PCR analysis of acquired isolates and comparison among all collected fingerprints confirmed the spices to be the source of both S. aureus and S. haemolyticus strains identified in raw meat paste. The additional rep-PCR analysis of the S. epidermidis collection confirmed usability and performance of this method. The antibiotic susceptibility to fourteen individual antibiotics has been examined among the collected staphylococci strains.

First, the 12-point IntMDCT is converted into the 6-point type-]V discrete cosine transform (DCT-IV) , which is then factorized into a product of 7 Givens rotation matrices. The integer type Givens rotation matrices are approximated by lifting scheme, modulo transform and infinity norm rotation transform, respectively. Finally, the speed and accuracy of these three IntMDCT algorithms are compared in both lossless and lossy audio compression. The experimental results show that in the three algorithms , the IntMDCT algorithm based on the modulo transform has the highest computation speed. The IntMDCT algorithm based on the infinity norm rotation transform has the highest accuracy, and can achieve the highest signal to noise ratio (SNR) in lossy audio compression.

    This study systematically reviews the literature on the occurrence, incidence and case fatality rate (CFR) of invasive nontyphoidal Salmonella (iNTS) disease in Africa from 1966 to 2014. Data on the burden of iNTS disease in Africa are sparse and generally have not been aggregated, making it difficult to describe the epidemiology that is needed to inform the development and implementation of effective prevention and control policies. This study involved a comprehensive search of PubMed and Embase databases. It documents the geographical spread of iNTS disease over time in Africa, and describes its reported incidence, risk factors and CFR. We found that Nontyphoidal Salmonella (NTS) have been reported as a cause of bacteraemia in 33 out of 54 African countries, spanning the five geographical regions of Africa, and especially in sub-Saharan Africa since 1966. Our review indicates that NTS have been responsible for up to 39% of community acquired blood stream infections in sub-Saharan Africa with an average CFR of 19%. Salmonella Typhimurium and Enteritidis are the major serovars implicated and together have been responsible for 91%% of the cases of iNTS disease, (where serotype was determined), reported in Africa. The study confirms that iNTS disease is more prevalent amongst Human Immunodeficiency Virus (HIV)-infected individuals, infants, and young children with malaria, anaemia and malnutrition. In conclusion, iNTS disease is a substantial cause of community-acquired bacteraemia in Africa. Given the high morbidity and mortality of iNTS disease in Africa, it is important to develop effective prevention and control strategies including vaccination. PMID:28056035

    Full Text Available Célèbre écrivain russe du début du XXe siècle, Ivan Šmelёv (1873-1950 doit, après les événements d’Octobre 1917, quitter la Russie avec sa femme. Le couple s’installe à Berlin en 1922 puis en France en 1923. Cette émigration forcée marque une nouvelle période dans la vie et dans l’œuvre de l’écrivain. Les biographies consacrées à Šmelёv s’accordent toutes sur un point : sa vie en exil fut extrêmement difficile et dès son arrivée, l’écrivain fut amer vis-à-vis de son pays d’accueil et de ses habitants. En effet, bien qu’il ait vécu un quart de siècle sur sa terre d’accueil, l’écrivain ne s’y intégra jamais vraiment, faisant le choix de rester en marge de la société française. Il reste à comprendre pourquoi Šmelёv n’a jamais pu s’y intégrer. Dans le présent article, je me propose de tenter de répondre à cette question en me basant sur les textes de l’écrivain. Pour ce faire, je retrace tout d’abord, étape par étape, les raisons qui l’ont poussé à s’installer en France. Ensuite, je me focalise sur l’évolution de ses ressentiments durant son exil. Enfin, dans la dernière partie, je mets en évidence quelques éléments de corrélation entre sa non-intégration dans la société d’accueil et son repli sur lui-même.

    Dry milk powders and functional ingredients frequently contain high levels of viable bacterial spores, some of which may result in growth of toxigenic Bacillus spp. in reconstituted and temperature-abused foods. Samples from nonfat dry milk (NFDM), infant milk formula (IMF), coffee creamer, lecithin, and cocoa powder were subjected to a short heat treatment followed by enrichment in tryptone phosphate glucose yeast extract (TPGY) broth at 32 degrees C for 12-25 hours to obtain cell densities of 10(6) CFU ml(-1). DNA was extracted using a modification of established protocol, leading to the development of an optimized method for each food system. Purified DNA was amplified by rep-PCR using extragenic sequence-targeting primers and optimized for each food. PCR fingerprints from each food were analyzed electrophoretically for banding patterns earlier correlated to that of enterotoxigenic Bacillus spp. and Bacillus cereus positive control DNA fingerprints. Reverse passive latex agglutination (RPLA) and Bacillus Diarrhoeal Enterotoxin Enzyme Linked Immunosorbent Assay (Tecra Diagnostics) confirmed the presence of HBL and NHE enterotoxin production in NFDM, Coffee creamer, infant milk formula, and two lecithin samples but not in cocoa powder. These results demonstrate the utility of rep-PCR not only as a tool for bacterial genotyping, but a unique means of quality control and hygiene monitoring in food microbiology.

Résumé Depuis quelques années, le web est devenu un média incontournable pour la diffusion de ressources multilingues. Cependant, les différences linguistiques constituent souvent un obstacle majeur aux échanges de documents scientifiques, culturels, pédagogiques et commerciaux. En plus de cette diversité linguistique, on constate le développement croissant de bases de données et de collections composées de différents types de documents textuels ou multimédias, ce qui complexifie également le processus de repérage documentaire. Par exemple, les collections d’images numériques sont aussi nombreuses que diversifiées. Le besoin de repérer une image spécifique dans diverses collections est devenu une préoccupation partagée par plusieurs communautés. La croissance du web a mis en relief le besoin pressant de se doter d’outils propres à la description des images dans le but de faciliter leur repérage, puisque l’on retrouve celles-ci dans la plupart des ressources disponibles. Cette recherche compare le repérage d’images dans deux contextes linguistiques différents : un contexte monolingue, c’est-à-dire que la langue de la requête (français est la même que la langue d’indexation (français; et un contexte multilingue où la langue de la requête (français est différente de la langue d’indexation (anglais.

    A cryptic 10.0-kb plasmid pG6303 from a multiplasmid-containing Lactobacillus plantarum G63 was studied. The analysis of replicon was facilitated by the construction of shuttle vectors and electrotransformation into L. plantarum. The pG6303 replicon included (i) an open reading frame encoding the putative Rep replication initiation protein; and (ii) the putative origin of replication. The Rep protein was expressed as a fusion with the hexa-histidine (His) at its C-terminal end and purified by Ni-affinity chromatography. The electrophoretic mobility shift assays in pG6303 showed that the purified Rep protein specifically bound from 5582 to 5945 bp, differing from the putative origin of replication of pG6303. We speculate that pG6303 replication is a new mode of plasmid replication.

    Functional biological materials are a growing research area with potential applicability in medicine and biotechnology. Using genetic engineering, the possibility to introduce additional functions into spider silk-based materials has been realized. Recently, a recombinant spider silk fusion protein, Z-4RepCT, was produced intracellularly in Escherichia coli and could after purification self-assemble into silk-like fibers with ability to bind antibodies via the IgG-binding Z domain. In this study, the use of the methylotrophic yeast Pichia pastoris for production of Z-4RepCT has been investigated. Temperature, pH and production time were influencing the amount of soluble Z-4RepCT retrieved from the extracellular fraction. Purification of secreted Z-4RepCT resulted in a mixture of full-length and degraded silk proteins that failed to self-assemble into fibers. A position in the C-terminal domain of 4RepCT was identified as being subjected to proteolytic cleavage by proteases in the Pichia culture supernatant. Moreover, the C-terminal domain was subjected to glycosylation during production in P. pastoris. These observed alterations of the CT domain are suggested to contribute to the failure in fiber assembly. As alternative approach, Z-4RepCT retrieved from the intracellular fraction, which was less degraded, was used and shown to retain ability to assemble into silk-like fibers after enzymatic deglycosylation.

  15. In vitro recombination catalyzed by bacterial class 1 integron integrase IntI1 involves cooperative binding and specific oligomeric intermediates.

    Directory of Open Access Journals (Sweden)

    Véronique Dubois

    Full Text Available Gene transfer via bacterial integrons is a major pathway for facilitating the spread of antibiotic resistance genes across bacteria. Recently the mechanism underlying the recombination catalyzed by class 1 integron recombinase (IntI1 between attC and attI1 was highlighted demonstrating the involvement of a single-stranded intermediary on the attC site. However, the process allowing the generation of this single-stranded substrate has not been determined, nor have the active IntI1*DNA complexes been identified. Using the in vitro strand transfer assay and a crosslink strategy we previously described we demonstrated that the single-stranded attC sequences could be generated in the absence of other bacterial proteins in addition to IntI. This suggests a possible role for this protein in stabilizing and/or generating this structure. The mechanism of folding of the active IntI*DNA complexes was further analyzed and we show here that it involves a cooperative binding of the protein to each recombination site and the emergence of different oligomeric species specific for each DNA substrate. These findings provide further insight into the recombination reaction catalyzed by IntI1.

    The ESO/MPG WFI and the INT WFC wide field archives comprising 330,000 images were mined to search for serendipitous encounters of known Near Earth Asteroids (NEAs) and Potentially Hazardous Asteroids (PHAs). A total of 152 asteroids (44 PHAs and 108 other NEAs) were identified using the PRECOVERY software, their astrometry being measured on 761 images and sent to the Minor Planet Centre. Both recoveries and precoveries were reported, including prolonged orbital arcs for 18 precovered objects and 10 recoveries. We analyze all new opposition data by comparing the orbits fitted before and after including our contributions. We conclude the paper presenting Mega-Precovery, a new online service focused on data mining of many instrument archives simultaneously for one or a few given asteroids. A total of 28 instrument archives have been made available for mining using this tool, adding together about 2.5 million images forming the Mega-Archive.

Durante los diferentes movimientos de los vehículos, cada conductor precisa contar con las posibilidades técnicas de su equipo en cuanto a velocidad y capacidad de carga, tratando de realizar las operaciones con un gasto mínimo de tiempo, medios materiales y financieros, y con las mejores condiciones de confort y seguridad. El confort y seguridad del sistema de redes estará en función del estado técnico de la carretera en estudio y del sistema de gestión para su conservación. La premisa fundamental para la organización del servicio de mantenimiento, reparación y/o reconstrucción del sistema de carreteras, incluyendo sus puentes, se determinará atendiendo a los datos extraídos del inventario de toda la red vial existente en el territorio nacional. Para disponer de una Base de Datos confiable, que recoja con fiabilidad el estado técnico de la red vial y los puentes de carretera, se precisa de la combinación de las técnicas de inspección, levantamiento de patologías y diagnóstico del estado técnico de dicha red y sus puentes, unido a las técnicas de modelación e instrumentación que permitan realizar una correcta evaluación y un diagnóstico eficaz, además de contar con un excelente sistema de gestión de conservación en función del grado de deterioro de la red vial y de todos sus elementos componentes, incluyendo sus puentes.

    Methods for identifying and following microorganisms in the environment such as soils, water and plant association have been highly developed in recent years. In this study, we used rep-PCR for the characterization of Rhizobium bacteria isolated from legume trees native of Uruguay which permitted to follow them in plant inoculation assays. Among the primers used, ERIC and BOX1AR, the latter allowed the differentiation of isolates from different legumes and the finding of a high level of homology among rhizobia that nodulate the same legume species. Besides, it demonstrated that the profiles of the isolates recovered from nodules of Acacia caven, were identical to the ones used as inoculants; this confirmed the efficiency of these methods to follow these diazotrophs in the environment.

    Full Text Available The bacterial strain Bacillus cereus is closely related to Bacillus thuringiensis, although any genetic relationship between the two strains is still in debate. Using rep-PCR genomic fingerprinting, we established the genetic relationships between Brazilian sympatric populations of B. cereus and B. thuringiensis simultaneously collected from two geographically separate sites. We observed the formation of both B. thuringiensis and B. cereus clusters, as well as strains of B. cereus that are more closely related to B. thuringiensis than to other B. cereus strains. In addition, lower genetic variability was observed among B. thuringiensis clusters compared to B. cereus clusters, indicating that either the two species should be categorized as separate or that B. thuringiensis may represent a clone from a B. cereus background.

    Various studies have linked alcohol dependence phenotypes to chromosome 4. One candidate gene is NACP (non-amyloid component of plaques), coding for alpha synuclein. Recently, it has been shown that alpha synuclein mRNA is increased in alcohol-dependent patients within withdrawal state. This increase is significantly associated with craving, especially obsessive craving. On the basis of these observations, the present study analysed two polymorphic repeats within the NACP gene. We found highly significant longer alleles of NACP-REP1 in alcohol-dependent patients compared with healthy controls (Kruskal-Wallis test, chi(2)=99.5; df=3, Pcraving, a key factor in the genesis and maintenance not only of alcoholism but also of addiction in general.

    2011-12-01

    Full Text Available Abstract Background Geminiviruses mainly infect terminally differentiated tissues and cells in plants. They need to reprogramme host cellular machinery for DNA replication. This process is thought to be mediated by inactivation of cell-cycle repressor proteins and by induction of host DNA synthesis protein expression through actions of the geminviral replication initiator protein (Rep. Findings Exploiting a Nicotiana benthamiana pOri2 line, which is transformed with a transgene consisting of a direct repeat of the African cassava mosaic virus (ACMV-replication origin (Ori flanking a non-viral DNA region, and virus-induced RNA silencing (VIGS, the impact of host gene expression on replication of the ACMV-derived replicon was investigated. The ACMV Rep trans-replicated the viral episomal replicon in leaves of young but not older pOri2 plants. Upon VIGS-mediated down-regulation of N. benthamiana NbRBR1, the retinoblastoma-related protein gene coding for a negative cell-cycle suppressor, recovered the ability of ACMV Rep for trans DNA replication, whereas the silencing of NbPCNA coding for the sliding clamp of DNA polymerase had no effect. Conclusions These results suggest that the cellular machinery for DNA replication in differentiated tissues of older leaves cannot be reprogrammed by Rep alone but may need other uncharacterised viral and plant factors.

    To understand the change of the dominant serogroup of Shigella spp., their antimicrobial resistance over more than two decades in Tianjin, their phylogenetic similarity and to determine their evolutionary biology by using REP-PCR and MLST in order to study their epidemiological character. Multi-locus Sequence Typing was performed to determine their lineage and phylogenetic similarity. REP-PCR typing was used to study the homology of their genomic DNA. The isolated rate of group D Shigella in 2009 and 2010 had obviously increased. Antimicrobial susceptibility test results showed that the resistant rates of the 1981-1983 Shigella flexneri to tetracycline, streptomycin and chloramphenicol varied from 76.47 to 100%, they were all sensitive to other antibiotics. During 2009-2010, the resistance rates of the isolated Shigella flexneri to gentamicin, amikacin, third and fourth Generation Cephalosporins and quinolones had increased. MLST results produced five sequence types and two sequence type complexes. REP-PCR showed DNA band similarities between the 1981-1983 and 2009-2010 strains. The dominant serogroup of Shigella in Tianjin has changed from Shigella flexneri to Shigella sonnei. Increased drug resistance of Shigella flexneri is higher than Shigella sonnei because a great variety of antibiotics has been used. The MLST results showed that the 1981-1983 strains had the same sequence type with some of the 2009-2010 strains. Combination of MLST and REP-PCR produced better discriminatory power than using either method alone. PMID:23205184

    Full Text Available In this study, Pseudomonas syringe pathovars isolated from olive, tomato and bean were identified by species-specific PCR and their genetic diversity was assessed by repetitive extragenic palindromic (REP-PCR. Reverse universal primers for REP-PCR were designed by using the bases of A, T, G or C at the positions of 1, 4 and 11 to identify additional polymorphism in the banding patterns. Binding of the primers to different annealing sites in the genome revealed additional fingerprint patterns in eight isolates of P. savastanoi pv. savastanoi and two isolates of P. syringae pv. tomato. The use of four different bases in the primer sequences did not affect the PCR reproducibility and was very efficient in revealing intra-pathovar diversity, particularly in P. savastanoi pv. savastanoi. At the pathovar level, the primer BOX1AR yielded shared fragments, in addition to five bands that discriminated among the pathovars P. syringae pv. phaseolicola, P. savastanoi pv. savastanoi and P. syringae pv. tomato. REP-PCR with a modified primer containing C produced identical bands among the isolates in a pathovar but separated three pathovars more distinctly than four other primers. Although REP-and BOX-PCRs have been successfully used in the molecular identification of Pseudomonas isolates from Turkish flora, a PCR based on inter-enterobacterial repetitive intergenic concensus (ERIC sequences failed to produce clear banding patterns in this study.

    Various mutations in PARK2 gene, which encodes the protein parkin, are significantly associated with the onset of autosomal recessive juvenile Parkinson (ARJP) in neuronal cells. Parkin is a multi domain protein, the N-terminal part contains the Ubl and the C-terminal part consists of four zinc coordinating domains, viz., RING0, RING1, in between ring (IBR) and RING2. Disease mutations are spread over all the domains of Parkin, although mutations in some regions may affect the functionality of Parkin more adversely. The mutations in the RING2 domain are seen to abolish the neuroprotective E3 ligase activity of Parkin. In this current work, we carried out detailed in silico analysis to study the extent of pathogenicity of mutations spanning the Parkin RING2 domain and the adjoining REP region by SIFT, Mutation Accessor, PolyPhen2, SNPs and GO, GV/GD and I-mutant. To study the structural and functional implications of these mutations on RING2-REP domain of Parkin, we studied the solvent accessibility (SASA/RSA), hydrophobicity, intra-molecular hydrogen bonding profile and domain analysis by various computational tools. Finally, we analysed the interaction energy profiles of the mutants and compared them to the wild type protein using Discovery studio 2.5. By comparing the various analyses it could be safely concluded that except P437L and A379V mutations, all other mutations were potentially deleterious affecting various structural aspects of RING2 domain architecture. This study is based purely on computational approach which has the potential to identify disease mutations and the information could further be used in treatment of diseases and prognosis.

    Background Streptococcus mutans and Streptococcus sobrinus are considered to be important bacterial species in the initiation of human dental caries. Therefore, the establishment of a reliable genotyping method to distinguish S. mutans from S. sobrinus is of central importance. Objective We assessed the usefulness of repetitive extragenic palindromic polymerase chain reaction (rep-PCR) using ERIC primer banding patterns in differentiating S. mutans and S. sobrinus. Design Five S. mutans and two S. sobrinus prototype strains and 50 clinical isolates (38 S. mutans serotype c, 4 S. sobrinus serotype d, and 8 S. sobrinus serotype g) were examined. The banding patterns of amplicons generated were compared among the prototype strains and clinical isolates, to find common bands that distinguish S. mutans and S. sobrinus. Results Multiple banding patterns were seen with all strains tested. The representative strains of S. mutans tested revealed six unique, strong bands at 2,000 bp, 1,700 bp, 1,400 bp, 1,100 bp, 850 bp, and 250 bp, whereas S. sobrinus had seven strong bands at 2,000 bp, 1,800 bp, 1,100 bp, 900 bp, 800 bp, 600 bp, and 550 bp. The band at 1,100 bp was the only band that was observed in both S. mutans and S. sobrinus. Furthermore, most clinical S. mutans isolates revealed identical banding patterns. All S. mutans had amplicons at 1,700 bp, 850 bp, and 250 bp, whereas those of S. sobrinus were at 1,100 bp, 900 bp, and 800 bp. Conclusions These results indicate that using rep-PCR with the ERIC primers can distinguish between S. mutans and S. sobrinus. PMID:22145074

    2015-01-01

    Full Text Available RESUMO:As relações de conflito entre os grupos sociais constituem um tópico relevante para a filosofia política, e as maneiras distintas como elas são interpretadas dependem de uma visão mais ampla sobre as condições apropriadas a um Estado bem-ordenado. Maquiavel, por exemplo, ao refletir sobre o caso da Roma Antiga, procurou refutar aqueles que condenavam os tumultos entre os nobres e a plebe da cidade, como se eles tivessem provocado apenas males à república. Para o autor, tais tumultos estavam entre as principais causas da liberdade romana, visto que a diferença nos “humores” dos grandes e do povo resultou em embates que deram origem às leis favoráveis à liberdade. Rousseau, por sua vez, descreveu a existência de “associações particulares” dentro da sociedade civil como algo potencialmente nocivo à harmonia da república, pois cada uma delas contém um interesse particular passível de se sobrepor ao bem comum, nas deliberações públicas, prejudicando o prevalecimento da vontade geral. Ainda para o genebrino, a ocorrência de longos debates e de tumultos nas assembleias populares poderia ser um sinal de divisões internas capazes de ocasionar a ruína do Estado. Frente a essas duas maneiras de conceber o papel político dos conflitos sociais, o objetivo deste trabalho é realizar uma análise comparativa das ideias de Maquiavel e de Rousseau.

    The effects of substrates of primary aerobic dehydrogenases, and inorganic phosphate on aerobic INT and CTC reduction in Escherichia coli were examined. In general, INT produced less formazan than CTC, but INT (+) cell counts remained near values of CTC (+) cells. INT and CTC (+) cell numbers were higher than plate counts on R2A medium using succinate, formate, lactate, casamino acids, glucose, glycerol (INT only) and no substrate. Formate resulted in the greatest amount of INT and CTC formazan. Reduction of both INT and CTC was inhibited above 10 mmol l-1 phosphate, and this appeared to be related to decreased rates of O2 consumption. Formation of fluorescent CTC (+), but not INT (+) cells was also inhibited in a concentration dependent manner by phosphate above 10 mmol l-1. From light microscopic observations it appeared CTC formed increasing amounts of poorly or non-fluorescent formazan with increasing phosphate. Therefore, use of phosphate buffer in excess of 10 mmol l-1 may not be appropriate in CTC and INT reduction assays.

    We identified the characteristics of myeloid-derived suppressor cells (MDSCs) and investigated their mechanism of induction and their functional role in allograft rejection using a murine corneal allograft model. In mice, MDSCs coexpress CD11b and myeloid differentiation antigen Gr-1. Gr-1(+)CD11b(+) cells infiltrated allografted corneas between 4 d and 4 wk after surgery; however, the frequencies of Gr-1(+)CD11b(+) cells were not different between accepted and rejected allografts or in peripheral blood or BM. Of interest, Gr-1(int)CD11b(+) cells, but not Gr-1(hi)CD11b(+) cells, infiltrated the accepted graft early after surgery and expressed high levels of immunosuppressive cytokines, including IL-10, TGF-β, and TNF-related apoptosis-inducing ligand. This population remained until 4 wk after surgery. In vitro, only high dose (>100 ng/ml) of IFN-γ plus GM-CSF could induce immunosuppressive cytokine expression in Gr-1(int)CD11b(+) cells. Furthermore, adoptive transfer of Gr-1(int)CD11b(+) cells reduced T cell infiltration, which improved graft survival. In conclusion, high-dose IFN-γ in allograft areas is essential for development of Gr-1(int)CD11b(+) MDSCs in corneal allografts, and subtle environmental changes in the early period of the allograft can result in a large difference in graft survival.

    The IntFOLD server is a novel independent server that integrates several cutting edge methods for the prediction of structure and function from sequence. Our guiding principles behind the server development were as follows: (i) to provide a simple unified resource that makes our prediction software accessible to all and (ii) to produce integrated output for predictions that can be easily interpreted. The output for predictions is presented as a simple table that summarizes all results graphically via plots and annotated 3D models. The raw machine readable data files for each set of predictions are also provided for developers, which comply with the Critical Assessment of Methods for Protein Structure Prediction (CASP) data standards. The server comprises an integrated suite of five novel methods: nFOLD4, for tertiary structure prediction; ModFOLD 3.0, for model quality assessment; DISOclust 2.0, for disorder prediction; DomFOLD 2.0 for domain prediction; and FunFOLD 1.0, for ligand binding site prediction. Predictions from the IntFOLD server were found to be competitive in several categories in the recent CASP9 experiment. The IntFOLD server is available at the following web site: http://www.reading.ac.uk/bioinf/IntFOLD/.

    Full Text Available Cette étude cherchera à montrer qu’une lecture des textes autographes de la liasse 8 des Pensées de Pascal titrée "Divertissement" permet de remonter à une figure du rapport à soi originale et distincte de la forme ultérieure de la subjectivité. Il est nécessaire pour cela de partir de l’étude des fragments manuscrits et d’une réflexion sur la méthode permettant d’en obtenir une lecture, et d’en produire des copies figurées. Sur cette base, il est possible de montrer que l’intériorité pascalienne se définit comme désertée par la présence divine : le fond du coeur est dans "l’homme sans Dieu" un gouffre infini et la connaissance de soi une saisie de son néant propre.This study will analyze the eighth part of Pascal’s Pensées ("Divertissement" and put in light that it forms a specific kind of relationship to oneself, that occurred before our present subjectivity. In that purpose, we must consider the autographs and have a method to get the text readable, with figured copies. On that basis, it may be shown that pascalian personal interior is an inside desert space, left by god : in the "man without God", the inside of the heart is an infinite empty hole and the knowledge of oneself is a perception of one’s nothingness.

    To facilitate molecular genetic studies of Streptomyces ambofaciens that produces spiramycin, a commercially important macrolide antibiotic used in human medicine against Gram-positive pathogenic bacteria, the conditions for the conjugal transfer of DNA from E. coli to S. ambofaciens were established using a bacteriophage phiC31 att/int system. The transconjugation efficiency of S. ambofaciens varied with the medium used; the highest frequency was obtained on AS-1 medium containing 10 mM MgCl(2) without heat treatment of the spores. In addition, by cloning and sequencing the attB site, we identified that S. ambofaciens contains a single attB site within an ORF coding for a pirin homolog, and its attB site sequence shows 100% nt identity to the sequence of S. coelicolor and S. lividans, which have the highest efficiency in transconjugation using the phiC31 att/int system.

    Quaternary chalcogenides form a large class of materials that continue to be of interest for energy-related applications. Certain compositions have recently been identified as possessing good thermoelectric properties however these materials typically have the kesterite structure type with limited variation in composition. In this study we report on the structural, optical and electrical properties of the quaternary chalcogenides CuZn2InTe4 and CuCd2InTe4 which crystallize in the modified zinc-blende crystal structure, and compare their properties with that of CuZn2InSe4. These p-type semiconductors have direct band gaps of about 1 eV resulting in relatively high Seebeck coefficient and resistivity values. This work expands on the research into quaternary chalcogenides with new compositions and structure types in order to further the fundamental investigation of multinary chalcogenides for potential thermoelectrics applications.

    Genetically modified (GM) crops is considered the fastest adopted crop technology in the history of modern agriculture. However, possible undesirable and unintended effects must be considered during the research steps toward development of a commercial product. In this report we evaluated effects of a common bean virus resistant line on arthropod populations, considered as non-target organisms. This GM bean line (named M1/4) was modified for resistance against Bean golden mosaic virus (BGMV) by expressing a mutated REP protein, which is essential for virus replication. Biosafety studies were performed for a period of three years under field conditions. The abundance of some species was significantly higher in specific treatments in a particular year, but not consistently different in other years. A regular pattern was not observed in the distribution of insects between genetically modified and conventional treatments. Data analyses showed that minor differences observed can be attributed to random variation and were not consistent enough to conclude that the treatments were different. Therefore the present study indicates that the relative abundance of species are similar in transgenic and non-transgenic fields.

    In the FP6 European project OSIRIS, Integrated Testing Strategies (ITSs) for relevant toxicological endpoints were developed to avoid new animal testing and thus to reduce time and costs. The present paper describes the development of an ITS for repeated-dose toxicity called RepDose ITS which evaluates the conditions under which in vivo non-guideline studies are reliable. In a tiered approach three aspects of these "non-guideline" studies are assessed: the documentation of the study (reliability), the quality of the study design (adequacy) and the scope of examination (validity). The reliability is addressed by the method "Knock-out criteria", which consists of four essential criteria for repeated-dose toxicity studies. A second tool, termed QUANTOS (Quality Assessment of Non-guideline Toxicity Studies), evaluates and weights the adequacy of the study by using intra-criterion and inter-criteria weighting. Finally, the Coverage approach calculates a probability that the detected Lowest-Observed-Effect-Level (LOEL) is similar to the LOEL of a guideline study dependent on the examined targets and organs of the non-guideline study. If the validity and adequacy of the non-guideline study are insufficient for risk assessment, the ITS proposes to apply category approach or the Threshold of Toxicological Concern (TTC) concept, and only as a last resort new animal-testing.

    Full Text Available El presente trabajo procura ofrecer un análisis del proceso histórico que llevó a la extinción de los cabildos en Córdoba, en 1824. A partir de la documentación tanto capitular como de las instituciones provinciales del período que transcurre entre 1815 y 1824, se intenta demostrar que aquella medida no fue necesariamente un resultado de la clásica conflictividad entre instituciones de orden provincial y municipal, así como que la misma no implicó una alteración sustancial de los patrones estructurales de representación política ni de la relación entre ciudad y campaña. La antigua noción de República, como gobierno doméstico en cabeza de "muchas familias", sirve de común denominador para explicar estas continuidades, a pesar de la mutación a nivel del lenguaje institucional que implicó la organización constitucional de la provincia y la posterior extinción de sus instituciones municipales.

    2015-01-01

    Pulsed-field gel electrophoresis (PFGE) is the 'gold standard' for genotyping of methicillin-resistant Staphylococcus aureus (MRSA); however, the DiversiLab (DL) system, based on rep-PCR, is faster, simpler and could be better adapted to daily routine hospital work. We genotyped 100 MRSA isolates using PFGE, DL, and spa typing, and evaluated the discriminatory power of each technique and the correlation between them by Simpson's index(SI) and adjusted Rand coefficient (ARI), respectively. The isolates were from clinical samples from eight hospitals in Extremadura (Spain) during 2010. DL separated the 100 MRSA into 18 patterns, with 69% of the isolates grouped into four predominant patterns. spa typing reported 17 spa types, classifying 69% of MRSA into two major types (t067 and t002). PFGE revealed the existence of 27 patterns, gathering 54% of MRSA into three pulse types (E8a, E7a and E7b). SI values were 0.819, 0.726, 0.887 and 0.460 for DL, spa typing, PFGE and CC-BURP, respectively. ARI values of DL over PFGE, spa typing and CC-BURP were 0.151, 0.321 and 0.071, respectively. DL has less discriminatory power than PFGE but more than spa typing. The concordance of DL with PFGE is low, primarily because DL does not discriminate between the three predominant MRSA pulse types in our environment.

  2. Improving Switching Performance of Power MOSFETs Used in High Rep-Rate, Short Pulse, High-Power Pulsers

    Energy Technology Data Exchange (ETDEWEB)

    2006-09-19

    As their switching and power handling characteristics improve, solid-state devices are finding new applications in pulsed power. This is particularly true of applications that require fast trains of short duration pulses. High voltage (600-1200V) MOSFETs are especially well suited for use in these systems, as they can switch at significant peak power levels and are easily gated on and off very quickly. MOSFET operation at the shortest pulse durations is not constrained by the intrinsic capabilities of the MOSFET, but rather by the capabilities of the gate drive circuit and the system physical layout. This project sought to improve MOSFET operation in a pulsed power context by addressing these issues. The primary goal of this project is to improve the switching performance of power MOSFETs for use in high rep-rate, short pulse, high-power applications by improving the design of the gate drive circuits and the circuit layouts used in these systems. This requires evaluation of new commercial gate drive circuits and upgrading the designs of LLNL-developed circuits. In addition, these circuits must be tested with the fastest available high-voltage power MOSFETs.

Mateos presentó un proyecto de ley para que el gobierno clausurara y pusiera en subasta pública templos y casas curales ocupadas por la Compañía de Jesús. Dicha iniciativa generó la oposición de muchos intelectuales seguidores del positivismo, quienes, desde las páginas del periódico La Libertad, acusaron a Mateos de retrógrada y de intolerante, defensor de unos postulados ya caducos, como los de los movimientos de Ayutla y de Reforma. Esta crítica motivó, a su vez, la participación de Ignacio Manuel Altamirano en pro de la doctrina liberal, utilizando para ello las páginas del diario La República. Durante poco más de dos semanas, en dichos periódicos se debatió en torno a la conveniencia de uno u otro modelo filosófico para el futuro del país, el orden y el progreso versus la democracia y las libertades individuales.

From a total of 972 children with diarrhoea, 78% required to be hospitalized. The greatest number of cases were found during spring and summer in children from 1 to 11 months of age. Distribution of the main enteropathogens was: enteropathogenic Escherichia coli (EPEC) (29.4%), parasites (22%), Shigella (16.3%), enterotoxigenic Escherichia coli (ETEC) (14%) and rotavirus (12.9%). Highest incidence of rotavirus was registered in the coldest months and Shigella, ETEC, Salmonella and parasites in the warm months. The group of most affected children were from 1 to 11 months of age, with higher incidence of EPEC, Salmonella and rotavirus, and parasites were found in older children. ETEC and Shigella had no relationship with the age of children. The most frequent association was EPEC with rotavirus. This is the first finding of Salmonella zaiman in humans and of Salmonella hadar in Argentina. Cryptosporidium, etiological agent of serious diarrhoea in the immunocompetent, was isolated in 3.9% of our cases.

    Mast cells are rare tissue-resident immune cells that are involved in allergic reactions, and their numbers are increased in the lungs of asthmatics. Murine lung mast cells arise from committed bone marrow-derived progenitors that enter the blood circulation, migrate through the pulmonary endothelium, and mature in the tissue. In humans, mast cells can be cultured from multipotent CD34(+) progenitor cells. However, a population of distinct precursor cells that give rise to mast cells has remained undiscovered. To our knowledge, this is the first report of human lineage-negative (Lin(-)) CD34(hi) CD117(int/hi) FcεRI(+) progenitor cells, which represented only 0.0053% of the isolated blood cells in healthy individuals. These cells expressed integrin β7 and developed a mast cell-like phenotype, although with a slow cell division capacity in vitro. Isolated Lin(-) CD34(hi) CD117(int/hi) FcεRI(+) blood cells had an immature mast cell-like appearance and expressed high levels of many mast cell-related genes as compared with human blood basophils in whole-transcriptome microarray analyses. Furthermore, serglycin, tryptase, and carboxypeptidase A messenger RNA transcripts were detected by quantitative reverse transcription-polymerase chain reaction. Altogether, we propose that the Lin(-) CD34(hi) CD117(int/hi) FcεRI(+) blood cells are closely related to human tissue mast cells and likely constitute an immediate precursor population, which can give rise to predominantly mast cells. Furthermore, asthmatics with reduced lung function had a higher frequency of Lin(-) CD34(hi) CD117(int/hi) FcεRI(+) blood mast cell progenitors than asthmatics with normal lung function.

Le processus d’intégration des nouvelles aides-soignantes dans l’organisation est une étape informelle fondamentale au fait d’entrer dans le métier.

Ce décalage met en avant l’importance du processus de construction identitaire par le groupe de pairs. Les différentes approches sociologiques de la compétence ne proposent pas une vision aussi globale que celle de l’habilitation, qui permet un renversement de la perspective individualiste de formation.

    Prokaryote respiration is expected to be responsible for more than half of the community respiration in the ocean, but the lack of a practical method to measure the rate of prokaryote respiration in the open ocean resulted in very few published data leaving the role of organotrophic prokaryotes open to debate. Oxygen consumption rates of oceanic prokaryotes measured with current methods may be biased due to pre-incubation size filtration and long incubation times both of which can change the physiological and taxonomic profile of the sample during the incubation period. In vivo INT reduction has been used in terrestrial samples to estimate respiration rates, and recently, the method was introduced and applied in aquatic ecology. We measured oxygen consumption rates and in vivo INT reduction to formazan in cultures of marine bacterioplankton communities, Vibrio harveyi and the eukaryote Isochrysis galbana. For prokaryotes, we observed a decrease in oxygen consumption rates with increasing INT concentrations between 0.05 and 1 mM. Time series after 0.5 mM INT addition to prokaryote samples showed a burst of in vivo INT reduction to formazan and a rapid decline of oxygen consumption rates to zero within less than an hour. Our data for non-axenic eukaryote cultures suggest poisoning of the eukaryote. Prokaryotes are clearly poisoned by INT on time scales of less than 1 h, invalidating the interpretation of in vivo INT reduction to formazan as a proxy for oxygen consumption rates.

    Full Text Available La morfometría fluvial estudia diversas variables que caracterizan la forma de una cuenca de drenaje. El objetivo de este trabajo es aplicar el método morfométrico de cuencas naturales a una cuenca urbana. El área en estudio (6 km2 drena sus aguas al frente costero y comprende la localidad de Ingeniero White, República Argentina. Se realizó la jerarquización de la red de drenaje. Se identificaron tres subcuencas con escasa pendiente que presentan eventos de inundación, con mayor peligrosidad con precipitaciones extremas. Los valores de relación de longitud indicaron mayor concentración de energía en eventos de grandes avenidas. Los valores de relación de elongación demostraron que una de las subcuencas es de forma circular y presenta mayor velocidad en las avenidas de la escorrentía. Las dos cuencas más elongadas tienen mayor retardo en las avenidas. El mayor caudal del área en estudio fluye por la cuenca que posee el mayor número de orden y la mayor superficie. Las otras dos cuencas están sujetas a crecientes instantáneas y de respuesta inmediata. Los valores de pendiente y de área aplicados a modelos hidrológicos e hidraúlico determinaron la sección de los conductos y canales. El caudal calculado para el área drenada fue de 22.41 m3/s.

    Full Text Available Con la participación de nueve especialistas de diferentes instituciones de Argentina y transcurridos más de 10 años desde la primera Lista Roja de la herpetofauna de la República Argentina realizada por la Asociación Herpetológica Argentina en el año 2000, se re-categorizaron los taxones de Testudines presentes en el país incorporando nueva información taxonómica, biológica y ecológica y, aplicando correcciones metodológicas. Como resultado, de los 14 taxones de tortugas continentales y marinas, nueve quedaron incluidas en la presente Lista Roja bajo algún grado de amenaza, tres En Peligro, tres Amenazadas y tres Vulnerables, mientras que dos fueron categorizadas como No Amenazadas y tres son Insuficientemente Conocidas. En la evaluación de las tres especies de tortugas marinas, que frecuentan las costas del Mar Argentino, se homologaron las categorías con las de IUCN (2011. Respecto de la categorización anterior, se agregó la especie Phrynops geoffranus (Insuficientemente Conocida, se sinonimizaron dos especies, disminuyó el número de especies En Peligro de tres a dos y se incrementó el de Vulnerables de una a tres. Los pocos cambios resultantes de la presente categorización de las tortugas de Argentina respecto de la anterior podría reflejar la escasez de estudios realizados sobre este grupo en la última década y la necesidad de promoverlos.

    Full Text Available This study analyzes the development of afro-descendant women during the Republic of Cuba (1902-1959. First of all, works dedicated to Cuban women as a gender are assessed on one hand and to Afro culture on the other in order to show the extent to which Afro-Cuban women have been neglected by historiography. Then black and mixed-race women are studied in relation to the entire male population and white women. The text is divided into three parts: educational areas, vocational integration and political mobility. The data enables us to affirm that Afro-Cuban women were doubly subjugated throughout the Republican period, because of their gender against men, and because of race against white women.El estudio analiza la trayectoria de las mujeres afrodescendientes durante la República de Cuba (1902-1959. En primer lugar, se realiza una valoración de las obras dedicadas a las mujeres cubanas como género, por un lado, y a la cultura afro, por otro, para demostrar hasta qué punto las mujeres afrocubanas han sido desatendidas por la historiografía. Después se pasa a examinar a las mujeres negras y mestizas en relación con la población masculina total y las mujeres blancas. El texto se divide en tres apartados: campo educativo, inserción laboral y movilidad política. Los datos permiten afirmar que las mujeres afrocubanas estuvieron doblemente sometidas durante todo el período republicano, por género frente a los hombres negros, por «raza» frente a las mujeres blancas.

L’introduction du gender mainstreaming communautaire a certes légitimé et promu l’action des chargées de mission aux droits des femmes et à l’égalité auprès des acteurs des politiques de l’emploi au niveau local. Ainsi, celles-ci ont initié une stratégie d’apprentissage de l’égalité reposant sur des mesures de sensibilisation et de formation. Toutefois, cette stratégie non contraignante se heurte à des limites. Tout d’abord car elle manque encore de contrôles et de sanctions effectifs dans la mise en œuvre du Fonds Social Européen, qui permettraient de rendre le critère de la promotion de l’égalité plus contraignant. En outre, l’action des agent-e-s locaux de la politique de l’emploi est limitée par les difficultés liées au contexte social. Dans cette perspective, ceux-ci viennent en aide aux demandeurs d’emploi pour résoudre de nombreux problèmes, sur lesquels ils ont parfois peu d’influence, de sorte que le critère d’égalité entre les sexes peut apparaître secondaire.In diesem Artikel wird die konkrete Umsetzung des sog.

    Full Text Available The Republic of the dreams is an “Atlantic novel” and as such it develops a narrative on the trip and the memory of a family of Spanish origin in the contemporary Brazil. The work investigates the process of immigration and adjustment of a Galician patriarchal and capitalist, predestined to the social success. A consecration that will go up to his last consequences, coming back to his village, of which went out in 1913, to marry the daughter of a nobleman. Founder of a lineage hispanic-brazilian will remain caught in the profit that he itself interweaves on having taken part of the networks and the oligarchic practices that dominate in the country. Thus the authoress re-composes a statement ethnic-historical where she represents the ethnic segmentation of the condition state-nation and institutes the memory and the culture as elements of resistance.

    La República de los sueños es una “novela atlántica” y como tal desarrolla una narrativa sobre el viaje y la memoria de una familia de origen español en el Brasil contemporáneo. La obra indaga el proceso de inmigración y adaptación de un gallego patriarcal y capitalista, predestinado al éxito social. Una consagración que llevará hasta sus últimas consecuencias, retornando a su aldea, de la cual salió en 1913, para casarse con la hija de un hidalgo. Fundador de un linaje hispanobrasileño quedará atrapado en el lucro que él mismo entreteje al participar de las redes y las prácticas oligárquicas que dominan en el país. De este modo la autora recompone un relato etnohistórico donde representa la segmentación étnica del estado-nación e instituye la memoria y la cultura como elementos de resistencia.

  13. Hybrid lentivirus-phiC31-int-NLS vector allows site-specific recombination in murine and human cells but induces DNA damage.

    Directory of Open Access Journals (Sweden)

    Nicolas Grandchamp

    Full Text Available Gene transfer allows transient or permanent genetic modifications of cells for experimental or therapeutic purposes. Gene delivery by HIV-derived lentiviral vector (LV is highly effective but the risk of insertional mutagenesis is important and the random/uncontrollable integration of the DNA vector can deregulate the cell transcriptional activity. Non Integrative Lentiviral Vectors (NILVs solve this issue in non-dividing cells, but they do not allow long term expression in dividing cells. In this context, obtaining stable expression while avoiding the problems inherent to unpredictable DNA vector integration requires the ability to control the integration site. One possibility is to use the integrase of phage phiC31 (phiC31-int which catalyzes efficient site-specific recombination between the attP site in the phage genome and the chromosomal attB site of its Streptomyces host. Previous studies showed that phiC31-int is active in many eukaryotic cells, such as murine or human cells, and directs the integration of a DNA substrate into pseudo attP sites (pattP which are homologous to the native attP site. In this study, we combined the efficiency of NILV for gene delivery and the specificity of phiC31-int for DNA substrate integration to engineer a hybrid tool for gene transfer with the aim of allowing long term expression in dividing and non-dividing cells preventing genotoxicity. We demonstrated the feasibility to target NILV integration in human and murine pattP sites with a dual NILV vectors system: one which delivers phiC31-int, the other which constitute the substrate containing an attB site in its DNA sequence. These promising results are however alleviated by the occurrence of significant DNA damages. Further improvements are thus required to prevent chromosomal rearrangements for a therapeutic use of the system. However, its use as a tool for experimental applications such as transgenesis is already applicable.

    Full Text Available Aim: The present study was conducted for the development of ready-to-eat Vawksa rep (smoked pork product and to study the synergistic effect of curing ingredients and vacuum packaging on the physico-chemical and storage quality during refrigerated storage at (4°C±1°C for 15 days. Materials and Methods: Four different batches of Vawksa rep samples were prepared, i.e., T-1 (uncured, first cooked at 121°C for 15 min, and then smoked at 120°C for 30 min, T-2 (uncured, cooked, and smoked simultaneously at 120°C for 45 min, T-3 (cured, first cooked at 121°C for 15 min, and then smoked at 120°C for 30 min, and T-4 (cured, cooked, and smoked simultaneously at 120°C for 45 min. Results: Cooking yield was significantly higher (p<0.05 for the T-4. The pH of T-3 and T-4 samples was significantly higher (p<0.05 on day 15. The tyrosine value of all the samples increased significantly (p<0.05 among the different days of analysis. Thiobarbituric acid value was significantly (p<0.05 lower in T-3 sample both at the beginning and at the end of storage period. In microbiological profile, total plate count was lower in T-3 and T-4 than T-1 and T-2. However, Escherichia coli count was negative for T-3 and T-4 samples throughout the storage period. Among sensory attributes, T-3 and T-4 samples registered superior scores for color, flavor, texture, juiciness, and overall acceptability. Conclusion: Furthermore, Vawksa rep (smoked pork product could be prepared easily with little technology up-gradation and with a negligible escalation of production cost.

    Full Text Available O periódico ilustrado O Mequetrefe iniciou sua circulação no Rio de Janeiro em 1875 e manteve suas atividades até janeiro de 1893. No transcurso de sua trajetória, os temas políticos se sobressaíram tratados em irreverentes ilustrações e em textos de opinião. Em suas páginas foram noticiadas as principais mudanças políticas ocorridas no Brasil Imperial, como a Abolição dos Escravos e o fim do Império com o advento republicano. O Mequetrefe publicou, ao longo de seus anos de atuação, notícias e opiniões sobre o ideário republicano difundido por seus adeptos na Corte. Já no final dos anos 1880, o jornal defendia a mudança de governo no Brasil com a República. O objetivo principal deste artigo é, portanto, averiguar quais as considerações deste periódico que foram dirigidas à questão republicana até a Proclamação da República. Outro assunto a ser tratado aqui é como a República - por meio do emprego das alegorias femininas e seus propagandistas - surgiu nas produções artísticas dos desenhistas e nas opiniões dos colaboradores do jornal, que igualmente se dedicavam ao humor e a sátira.

  18. Loss-of-function mutations in Rab escort protein 1 (REP-1 affect intracellular transport in fibroblasts and monocytes of choroideremia patients.

    Directory of Open Access Journals (Sweden)

    Natalia V Strunnikova

    Full Text Available BACKGROUND: Choroideremia (CHM is a progressive X-linked retinopathy caused by mutations in the CHM gene, which encodes Rab escort protein-1 (REP-1, an escort protein involved in the prenylation of Rabs. Under-prenylation of certain Rabs, as a result of loss of function mutations in REP-1, could affect vesicular trafficking, exocytosis and secretion in peripheral cells of CHM patients. METHODOLOGY/PRINCIPAL FINDINGS: To evaluate this hypothesis, intracellular vesicle transport, lysosomal acidification and rates of proteolytic degradation were studied in monocytes (CD14+ fraction and primary skin fibroblasts from the nine age-matched controls and thirteen CHM patients carrying 10 different loss-of-function mutations. With the use of pHrodo BioParticles conjugated with E. coli, collagen I coated FluoSpheres beads and fluorescent DQ ovalbumin with BODYPY FL dye, we demonstrated for the first time that lysosomal pH was increased in monocytes of CHM patients and, as a consequence, the rates of proteolytic degradation were slowed. Microarray analysis of gene expression revealed that some genes involved in the immune response, small GTPase regulation, transcription, cell adhesion and the regulation of exocytosis were significantly up and down regulated in cells from CHM patients compared to controls. Finally, CHM fibroblasts secreted significantly lower levels of cytokine/growth factors such as macrophage chemoattractant protein-1 (MCP-1, pigment epithelial derived factor (PEDF, tumor necrosis factor (TNF alpha, fibroblast growth factor (FGF beta and interleukin (lL-8. CONCLUSIONS/SIGNIFICANCE: We demonstrated for the first time that peripheral cells of CHM patients had increased pH levels in lysosomes, reduced rates of proteolytic degradation and altered secretion of cytokines. Peripheral cells from CHM patients expose characteristics that were not previously recognized and could used as an alternative models to study the effects of different

    Choroideremia (CHM) is an X-linked chorioretinal dystrophy that is caused by mutations within a single gene, CHM Currently no effective treatment exists for these patients. Since over 30% of patients harbour nonsense mutations in CHM, nonsense suppression therapy using translational readthrough inducing drugs may provide functional rescue of REP1, thus attenuating progressive sight loss. Here, we employed two CHM model systems to systematically test the efficacy and safety of ataluren (PTC124) and its novel analog PTC-414: (1) the chm(ru848) zebrafish, the only nonsense mutation animal model of CHM harbouring a TAA nonsense mutation, and (2) a primary human fibroblast cell line from a CHM patient harbouring a TAG nonsense mutation. PTC124 or PTC-414 treatment of chm(ru848) embryos led to a ∼2.0-fold increase in survival, prevented the onset of retinal degeneration with reduced oxidative stress and apoptosis, increased rep1 protein by 23.1% (PTC124) and 17.2% (PTC-414) and restored biochemical function as confirmed through in vitro prenylation assays (98 ± 2% [PTC124] and 68 ± 5% [PTC-414]). In CHM(Y42X/y) fibroblasts, there was a recovery of prenylation activity following treatment with either PTC124 (42 ± 5%) or PTC-414 (36 ± 11%), although an increase in REP1 protein was not detected in these cells, in contrast to the zebrafish model. This comprehensive study on the use of PTC124 and PTC-414 as successful nonsense suppression agents for the treatment of CHM highlights the translational potential of these drugs for inherited retinal disease. © The Author 2016.

    Full Text Available Abstract Background The Int7G24A variant of transforming growth factor-beta receptor type I (TGFBR1 has been shown to increase the risk for kidney, ovarian, bladder, lung and breast cancers. Its role in colorectal cancer (CRC has not been established. The aims of this study were to assess the association of TGFBR1*Int7G24A variant with CRC occurrence, patient age, gender, tumour location and stage. Methods We performed a case-control study with 504 cases of sporadic CRC; and 504 non-cancerous age, gender and ethnically matched controls. Genotyping analysis was performed using allelic discrimination assay by real time PCR. Results The Int7G24A variant was associated with increased CRC incidence in an additive model of inheritance (P for trend = 0.005. No significant differences were found between Int7G24A genotypes and tumour location or stage. Interestingly, the association of the Int7G24A variant with CRC risk was significant in men (odds ratio 4.10 with 95% confidence intervals 1.41-11.85 for homozygous individuals; P for trend = 0.00023, but not in women. We also observed an increase in susceptibility to CRC for individuals aged less than 70 years. Conclusion Our data suggest that the Int7G24A variant represents a risk factor for CRC in the male Spanish population.

    Full Text Available Salmonelose é a infecção bacteriana de origem alimentar mais freqüente no Paraná, Brasil, e os surtos estão associados, principalmente, ao consumo de ovos, carne de aves e derivados. Os objetivos deste trabalho foram identificar os sorovares de Salmonella isolados de carcaças de frango e caracterizá-los molecularmente por REP e ERIC-PCR, assim como identificar os fagotipos de Salmonella Enteriditis. Dos 25 isolados de Salmonella spp. analisados, 18 foram identificados como Enteriditis, 4 como Braenderup, 2 como Worthington e 1 como infantis. Dos 18 isolados de Enteriditis, 14 foram PT4, 2 PT4a, 1 PT7 e 1 RDNC, por se tratar de colônia rugosa. REP-PCR forneceu padrão eletroforético distinto de 10 a 13 bandas distribuídas entre 120 e 2072 pb para cada sorovar diferente testado. A ERIC-PCR mostrou um padrão de 4 a 5 bandas entre 180 e 1000 pb e foi menos discriminativa quando comparada à REP-PCR. Os resultados encontrados confirmaram que a fagotipagem é uma ferramenta útil e discriminativa para o sorovar Enteriditis. Apesar do pequeno número de sorovares testados, os resultados sugerem que a REP-PCR parece ser um método atrativo a ser utilizado no futuro para a discriminação preliminar de sorovares de Salmonella.Salmonellosis is the most prevalent bacterial food-borne disease in the State of Paraná, Brazil, and the outbreaks are often associated with consumption of poultry products. The aim of this study was to serotype Salmonella strains isolated from chicken carcasses and characterize them molecularly using REP and ERIC-PCR.

    Huertas, Rafael

    2013-12-01

    Full Text Available The aim of this article is to explore the scientific content of the “sexual reform” movement which took place in Spain during the 1920s and 1930s, culminating during the Second Republic. It covers three essential aspects of this subject: 1 the introduction of the new science of sexology; 2 the interest in sex education for children; and 3 the passing of new marriage legislation (the Divorce Law of 1932. Areas of scientific discourse are identified, associated with a “modernization” of mores and based on secular and progressive assumptions. The conflict between biological or endocrinological approaches and psychoanalytical methods is discussed, with encouragement of a healthy, aware experience of sexuality becoming established as the central argument. Issues such as responsible parenting, birth control, prevention of mental disorders (linked to traumatic sexual experiences, etc. are analysed in the light of medical, psychological and legal sources, in relation to the reform of sexual mores and overcoming the bourgeois moral double standardEste artículo pretende estudiar los contenidos científicos del movimiento de “reforma sexual” que tuvo lugar en España en los años veinte y treinta y que culminó durante la Segunda República. Se abordan, al respecto, tres aspectos fundamentales: 1 la introducción de la nueva ciencia sexológica; 2 el interés por la educación sexual de los niños; y 3 la promulgación de una nueva legislación matrimonial (la ley de divorcio de 1932. Se identifican discursos científicos, asimilados a una “modernización” de las costumbres, siempre desde presupuestos laicos y progresistas. Se apunta la confrontación entre enfoques biologicistas o endocrinológicos y planteamientos psicoanalíticos, estableciéndose como eje argumental el fomento de una vivencia consciente y sana de la sexualidad.

    Repetitive-sequence-based polymerase chain reaction (Rep-PCR) method was used for analysis of genetic variability among bacterial populations from different world locations. Collection of 26 Czech and 13 foreign strains of Clavibacter michiganensis subsp. sepedonicus was amplified using BOX primer targeting to repetitive motif occurring in eubacterial genomes. Genetic fingerprints were visually compared and statistically evaluated by cluster analysis. Genetic similarity was estimated to be approximately 80% among all tested strains. Populations of these bacteria seem to be highly homogeneous; potential influence of geographic origin was not confirmed.

El trabajo tiene como objetivo analizar el proceso de evolución de la República de Moldova a la Unión Europea (UE, los compromisos asumidos por ambos y su cumplimiento. Además, voy a comparar los progresos realizados por Ucrania y RM hacia el acercamiento a la Unión Europea en los últimos años. Hace algunos años, Ucrania fue el país oriental con la perspectiva fundamental de la futura integración en la UE debido a sus cambios democráticos, hoy República de Moldova ha demostrado ser capaz de hacer más progresos en la promoción de la democracia y la aplicación de las reformas de gobernanza que Ucrania. Por otro lado, la relación entre la RM y la UE sigue siendo influenciada por las medidas adoptadas por la Federación de Rusia en la región donde todavía tiene influencia significativa, y tratar de mantener su presencia. Una de las herramientas fuertes de la influencia es la dependencia del suministro de energía y su falta de diversificación. El conflicto sin resolver de Transnistria es otro factor determinante de la falta de certeza en el proceso de europeización de la RM. El trabajo tiene como objetivo analizar la eficiencia de la europeización de la República de Moldova a través de la Política de Vecindad Europea, utilizando un método combinado constructivista y racionalista.

    声誉系统由于其聚集评价的特点,为恶意节点提供了可乘之机.一些恶意节点合谋形成GoodRep攻击组,相互虚假夸大,进而在高声誉值的掩饰下危及P2P网络安全.提出了GoodRep的攻击模型及其防御机制--RatingGuard,并给出了该机制的数学描述和模块化实现过程.RatingGuard通过分析推荐节点之间的评价行为相似度,对推荐节点进行聚类划分和异常检测,识别出存在的GoodRep攻击组节点,从而帮助声誉系统排除GoodRep攻击组的干扰,仿真结果表明,RatingGuard在GoodRep攻击组的抵制方面效果显著,有效提高了声誉系统在面对GoodRep攻击时的恶意节点检测卒.%Reputation systems are playing critical roles in P2P networks as a method to assess the trustworthiness of peers and to combat malicious peers. However, the characteristic of aggregating ratings makes reputation systems vulnerable to be abused by false ratings, and thus offering opportunities for malicious peers. They can conspire with each other to form a collusive clique and unfairly increase the reputation of them. Under the cover of high reputation, malicious peers can masquerade as trusted ones and violate P2P networks arbitrarily. This attack model, called GoodRep, is described in this paper. In order to defend against GoodRep attack, the RatingGuard scheme is proposed to secure P2P reputation systems. This scheme is built with three functional modules: DC, DP and AD. The data collection (DC) module supports the collection of the previous rating data among raters. The data processing (DP) module measures the rating similarity of raters' activities by analyzing these data. To identify GoodRep cliques, the abnormal detection (AD) module detects the abnormalities through clustering partition technology. The experimental results show that our RatingGuard scheme is effective in suppressing GoodRep attack, and the reputation system with RatingGuard gains higher detection ratio of

En 1827 José Manuel Restrepo publicó en París la primera parte, en seis volúmenes, de su soberbio trabajo sobre las luchas por la independencia de los estados de Venezuela, Ecuador y Colombia. Restrepo reconstruyó, detalle por detalle, una monumental cronología de todos aquellos eventos considerados por él como significativos en la guerra contra España. Propietario de documentos originales y un observador excepcional, en su calidad de miembro de la elite política criolla, el historiador Restrepo no se limitó a una simple descripción de los hechos.

    Full Text Available This study analyses the complex situation that the Dominican Republic experienced, resulting from the threat of Haiti, which once again invaded the Dominican Republic in 1855, as well as other more subtle interferences made by Great Britain, France, Spain and the United States. Diplomatic documentation of these two countries, along with bibliographic sources, have been used to investigate the beginning of foreign intervention in the Dominican Republic. The study of this process leads to the conclusion that the interference in Dominican politics by the First Consul of Spain in Santo Domingo helped accentuate Spanish-American rivalry.Esta investigación aborda la compleja coyuntura atravesada por la República Dominicana, como consecuencia de la amenaza de Haití, que invadió de nuevo el territorio dominicano en 1855, y de otras injerencias, si bien más sutiles, por parte de Gran Bretaña, Francia, España y Estados Unidos. Para indagar en el inicio del intervencionismo en la República Dominicana se ha utilizado documentación diplomática española y norteamericana, así como fuentes bibliográficas. El estudio de este proceso permite concluir que la injerencia en la política dominicana por parte del primer cónsul de España en Santo Domingo acentuó la rivalidad hispanoestadounidense.

    The article presents comparative evaluation of diagnostic value of technique REP- u RAPD-polymerase chain reaction applied under genetic typing of clinical isolates of Pseudomonas Aeruginosa. The strains are isolated in different hospital departments of medical institutions in adult (8 medical institutions; n = 145) and children (5 medical institutions; n = 151) medical networks. The results of study demonstrated different boundary capacity of three reactions. The Simpson discrimination index made up to 0.993, 0.875 and 0.639 for RAPD-, ERIC- and BOX-polymerase chain reaction correspondingly. The RAPD-polymerase chain reaction makes it possible to detect individual characteristics of strains. Out of two alternatives the REP-polymerase chain reaction demonstrated its advantage, besides only with one primer ERIC2. The BOX-polymerase chain reaction has a least discriminating capacity under typing of isolates P. aeruginosa, detecting only species' characteristics. The clinical strains P. aeruginosa are distributed on 24 genome groups and 52 isolates had individual genotypes. The evaluation of results of genetic typing permitted to point out both similarity of tendencies in propagation of strains of P. aeruginosa among hospitalized adults and adolescents and specificity of detection in neonatal clinics. It is obvious that hospitals of different profiles, including departments of reanimation and intensive therapy represent specific ecological environment significantly different in its level of endogenous and exogenous infection.

    The present study was conducted for the development of ready-to-eat Vawksa rep (smoked pork product) and to study the synergistic effect of curing ingredients and vacuum packaging on the physico-chemical and storage quality during refrigerated storage at (4°C±1°C) for 15 days. Four different batches of Vawksa rep samples were prepared, i.e., T-1 (uncured, first cooked at 121°C for 15 min, and then smoked at 120°C for 30 min), T-2 (uncured, cooked, and smoked simultaneously at 120°C for 45 min), T-3 (cured, first cooked at 121°C for 15 min, and then smoked at 120°C for 30 min), and T-4 (cured, cooked, and smoked simultaneously at 120°C for 45 min). Cooking yield was significantly higher (pproduct) could be prepared easily with little technology up-gradation and with a negligible escalation of production cost.

    The genetic diversity of the Stemphylium solani isolates from cotton was assessed by Enterobacterial Repetitive Intergenic Consensus (ERIC) and Repetitive Extragenic Palindromes (REP)-PCR fingerprinting. Twenty eight monosporic isolates of S. solani from cotton were used along with five isolates from tomato and one isolate of Alternaria macrospora from cotton for comparison. The dendrogram obtained revealed clear differences between the cotton and tomato isolates as well as between the tomato isolates from different geographic regions. The genetic relationships among S. solani isolates were also analyzed by sequencing the internal transcribed spacer (ITS) region of four isolates representing the three ERIC and REP groups. The tomato isolate from the State of São Paulo showed a distinct ITS sequence from that of the cotton isolates and tomato isolate from the State of Goiás, giving evidence that it belongs to a different genotype of S. solani. This is the first report of the entire sequence of the ITS1-5.8S-ITS2 regions of S. solani.

    Full Text Available Han sido pocos los estudios en la historiografía nacional sobre el proceso de producción y comercialización de libros en la República de Colombia durante el siglo xix. A partir del análisis de las actividades de los impresores, los escritores de textos, los comerciantes y las autoridades políticas en Cartagena, en este artículo se demostrará que la difusión de las letras en la sociedad republicana estuvo sujeta a la dinámica de impresión y comercialización de obras de educación impulsada por los hombres de letras desde las provincias. Esta dinámica se constituyó en la base inicial de la formación de un pequeño mercado editorial en la República y fue posible gracias a los usos de la libertad de imprenta, las demandas de la alfabetización y las negociaciones de los autores con los gobiernos locales y nacionales. Se busca así contribuir al análisis de un problema sobre el que existen escasos trabajos en el contexto regional colombiano.

    The pheromone-responsive conjugative plasmids of Enterococcus faecalis and the multiresistance plasmids pSK1 and pSK41 of Staphylococcus aureus are among the best studied plasmids native to Gram-positive bacteria. Although these plasmids seem largely restricted to their native hosts, protein sequence comparison of their replication initiator proteins indicates that they are clearly related. Homology searches indicate that these replicons are representatives of a large family of plasmids and a few phage that are widespread among the low G+C Gram-positive bacteria. We propose to name this family the RepA_N family of replicons after the annotated conserved domain that the initiator protein contains. Detailed sequence comparisons indicate that the initiator protein phylogeny is largely congruent with that of the host, suggesting that the replicons have evolved along with their current hosts and that intergeneric transfer has been rare. However, related proteins were identified on chromosomal regions bearing characteristics indicative of ICE elements, and the phylogeny of these proteins displayed evidence of more frequent intergeneric transfer. Comparison of stability determinants associated with the RepA_N replicons suggests that they have a modular evolution as has been observed in other plasmid families.

    Background The prognostic value of histologic response for osteosarcoma may have changed with induction chemotherapy schedules over time. We hypothesized that the increased intensity of induction therapy provided on INT0133 compared to the Children’s Cancer Group study CCG-782 would diminish the impact of histologic response on the risk of events after definitive surgery. Methods Retrospective analysis was performed for patients aged osteosarcoma enrolled on CCG-782 and INT0133. Clinical factors were evaluated for association with response and outcome. Good response was defined as <5% viable tumor at resection. Associations of response, study, and post-definitive surgery event-free survival (EFS-DS)were determined using Cox proportional hazard models. EFS-DS was estimated by Kaplan–Meier methodology. Results Data were available for 814 patients (206 CCG-782, 608 INT0133). For good responders, 10-year EFS-DS (±SE) was 75.4% ± 7.7% for CCG-782 and 70.8% ± 3.1% for INT0133. For poor responders, 10-year EFS-DS was 39.9% ± 4.9% for CCG-782 and 58.4% ± 3.1% for INT0133. Histologic response predicted outcome across studies (P < 0.0001). Significant interaction between study and histologic response was observed for EFS-DS (P = 0.011). Using proportional hazards regression, INT0133 poor responders had less risk of events compared to CCG-782 poor responders (relative hazard ratio (RHR) = 0.6:1), but good responders on INT0133 had a greater risk of events compared to CCG-782 good responders (RHR = 1.53:1). Conclusion We observed an inverse relationship between the predictive value of tumor necrosis and intensity of induction therapy, raising questions about the true prognostic value of histologic response. This highlights the need for novel markers to develop strategies for treatment in future trials. PMID:27128693

    Full Text Available The Spanish Second Republic set aside a big amount of resources, both human and economic, to survey the colonies. The consecutive republican governments kept a strong continuity on the schemes for colonial cartography, with no significant changes over the plans established in past periods. Cartographic work was focused in Morocco’s territory, and was carry out by a military unit named Comisión Geográfíca de Marruecos y Límites (Morocco’s Geographical Commission. This paper, built on primary sources, examines the institutional framework of Spanish colonial cartography during the republican period, identifies the leading mapmakers, and discusses the main cartographic surveys.

    Full Text Available Dans quelle mesure les manuscrits de travail des linguistes présentent-ils un intérêt pour les historiens de la linguistique ? Ce type de documents suscite, depuis quelques années, un regain indéniable de curiosité. L’exploration d’un nombre croissant de fonds d’archives de savants permet, au-delà d’un élargissement de l’horizon documentaire, d’envisager des approches comparatives entre différentes pratiques savantes. Elle ouvre aussi de nouvelles interrogations. Cet article réfléchit à l’intérêt historiographique de ce type de documents à partir d’un cas inédit : les papiers de travail consacrés à la linguistique générale du linguiste français, Joseph Vendryes (1875-1960. On met en évidence le double intérêt des archives privées de savants : documentaire et processuel. On aborde, dans un premier temps, les manuscrits d’un point de vue documentaire de façon à dégager ce que leur prise en compte modifie de notre connaissance de la linguistique générale de Joseph Vendryes. Le deuxième temps, consacré à la perspective processuelle, fait des manuscrits le lieu de l’observation de la méthode. Il s’agit d’analyser, à partir des manuscrits préparatoires à l’écriture d’un article, comment s’élabore un discours scientifique à caractère général sur le langage et les langues. Ces archives privées sont au carrefour de questionnements de recherche qui relèvent aussi bien d’une histoire conceptuelle que d’une histoire sociale des sciences du langage.

    Cosmogenic radionuclides, such as 10Be and 14C, share a common production signal, with their formation in the Earth's upper atmosphere modulated by changes to the geomagnetic field, as well as variations in the intensity of the solar wind. Here, we present 54 new 14C measurements from a terrestrial fen peat core extracted from the classical site of Tenaghi Philippon, NE Greece, contiguously spanning the time period between ~48,000 and 39,000 cal. BP. Utilising the most pronounced cosmogenic production peak of the last 100,000 years - that associated with the Laschamp geomagnetic excursion circa 41,000 years ago - we exploit this common production signal, comparing Greenland 10Be with our Tenaghi Philippon 14C record, thereby providing a means to assess the concordance between the radiocarbon (IntCal) and Greenland ice-core (GICC05) timescales themselves for this, the oldest portion of the radiocarbon technique.

    All IV iron complexes carry a risk of potentially fatal allergic type hypersensitivity reactions. The mechanism(s) behind these reactions is unknown but the limited data available suggests that classic IgE mediated allergy is exceedingly rare, if ever occurring. Iron-carbohydrate molecules are complex nano-particles and trying to reduce the risk of serious hypersensitivity to antibody binding of an artificial antibody seems meaningless. A recently published analysis of safety data from randomized clinical trials confirms the method reported by Neiser to be useless to predict reaction risk. In conclusion, the study by Neiser et al. is biased, contains no new information, and has no clinical relevance. We are concerned that the association of the authors with a commercial entity has caused a conflict of interest that biases not only the results, but the entire experimental setup against competitors.

    The bacterial diversity in two uranium waste piles was studied. Total DNA was recovered from a large number of soil samples collected from different sites and depths in the piles using two procedures for direct lysis. Significant differences in the bacterial composition of the samples were revealed by the use of rep-APD, RISA and 16S ARDREA. The 16S rDNA analyses showed that the uranium wastes were dominated by Acidithiobacillusferrooxidans and by several Pseudomonas species classified in the gamma-subdivision of the Proteobacteria. The three kinds of A. ferrooxidans 16S and IGS rDNA specific fragments that were found corresponded to the three phylogenetic groups recognised in this species. This microdiversity probably reflects the genetic adaptation of the uranium waste strains to different concentrations of heavy metals.

    Full Text Available La construcción del Estado debe estudiarse a través de la forma como se estructuran las agencias encargadas de cumplir cada una de sus funciones de regulación. Una de estas funciones es la regulación de los derechos de propiedad. Durante la República Liberal, como reacción a la fuerte movilización social, se promovió el desarrollo de instrumentos de regulación de la propiedad: colonización, parcelaciones, adjudicación de baldíos y, finalmente, un nuevo marco normativo. A pesar de sus intenciones, todos estos esfuerzos enfrentaron y fallaron en solucionar los retos que enfrenta toda organización en su crecimiento: la escasez de recursos, mantener el control de sus agentes, y mantener la simplicidad técnica.

La sorprendente propuesta del libro V de la República en la que las mejores mujeres debían gobernar con los mejores varones es consecuencia del principio, defendido por el autor, de que la vida política debía llevarse a cabo en virtud de la capacidad racional y el carácter de los gobernantes. La vulnerabilidad de Sócrates demostraba los límites de la política real que, a su vez, se basaba en el principio de dominio y el ideal masculino de entonces. Fue posible pensar en un gobierno de marginados, en el que tendrían asiento las mujeres amantes de la sabiduría y sus compañeros filósofos, porque se estaba erosionando el modelo masculino tradicional.

Este artículo está destinado a analizar estas tres dimensiones en el escenario rioplatense en las primeras décadas posteriores a la crisis monárquica y a la revolución y concluye con una reflexión general en torno a las redefiniciones ocurridas durante la segunda mitad del siglo XIX, cuando la República Argentina logró constituirse como tal y la soberanía popular pasó a absorber y condensar nuevos significados y sentidos. Si, por un lado, la resolución del problema del sujeto de imputación de la soberanía con la consitucionalización de tal sujeto en una única república, dotaría de un nuevo marco institucional a la forma de representar y de limitar el ejercicio de esa soberanía a partir de mediados del mencionado siglo; por el otro, la soberanía popular debía ahora responder a las nuevas demandas políticas y sociales que reclamaba la redefinición de la "cuestión democrática".

    The current EigenRep trust model could not make reputation punishment correction to the cheating behavior of malicious peers.To solve this problem,this paper improved the global reputation computing method.Many comprehensive factors in computing trust value are introduced in the mechanism.Moreover,another defect of EigenRep is that the system has to do the iterative calculation of global credibility within the whole network for each transaction,and this causes the system cost problem.To solve this problem,this paper presented a new trust mechanism which combines risk,local trustworthiness and global reputation.Simulations show that this mechanism could reduce the system cost greatly.At last,this paper realized an E-commerce platform system based on this trust mechanism.%针对EigenRep信任模型没有对节点恶意欺骗行为做出信誉惩罚修正的问题,改进了全局信誉的计算方法,即加入了影响因子,使得节点计算的全局信誉更客观.同时针对EigenRep模型每次交易都需要在全网络范围内做全局信誉的迭代计算从而导致系统开销过大的问题,提出了一种新的信任机制.实验表明,该机制结合风险、本地信任度和全局信誉的策略,可以大大减少系统开销,适合更大规模的网络环境的应用.最后,利用该机制实现了一个电子商务平台系统.

Esa preocupación por divulgar los resultados de su labor era una muestra más del dinamismo que había adquirido la Junta de Relaciones Culturales después de la reforma que experimentó en 1931. También recordaba a la actuación de la Junta para Ampliación de Estudios, que editaba sistemáticamente las memorias de sus actividades para dejar constancia pública del trabajo realizado. La analogía a este respecto no era casual.

    Full Text Available Abstract Background Euphorbia mosaic virus (EuMV is a member of the SLCV clade, a lineage of New World begomoviruses that display distinctive features in their replication-associated protein (Rep and virion-strand replication origin. The first entirely characterized EuMV isolate is native from Yucatan Peninsula, Mexico; subsequently, EuMV was detected in weeds and pepper plants from another region of Mexico, and partial DNA-A sequences revealed significant differences in their putative replication specificity determinants with respect to EuMV-YP. This study was aimed to investigate the replication compatibility between two EuMV isolates from the same country. Results A new isolate of EuMV was obtained from pepper plants collected at Jalisco, Mexico. Full-length clones of both genomic components of EuMV-Jal were biolistically inoculated into plants of three different species, which developed symptoms indistinguishable from those induced by EuMV-YP. Pseudorecombination experiments with EuMV-Jal and EuMV-YP genomic components demonstrated that these viruses do not form infectious reassortants in Nicotiana benthamiana, presumably because of Rep-iteron incompatibility. Sequence analysis of the EuMV-Jal DNA-B intergenic region (IR led to the unexpected discovery of a 35-nt-long sequence that is identical to a segment of the rep gene in the cognate viral DNA-A. Similar short rep sequences ranging from 35- to 51-nt in length were identified in all EuMV isolates and in three distinct viruses from South America related to EuMV. These short rep sequences in the DNA-B IR are positioned downstream to a ~160-nt non-coding domain highly similar to the CP promoter of begomoviruses belonging to the SLCV clade. Conclusions EuMV strains are not compatible in replication, indicating that this begomovirus species probably is not a replicating lineage in nature. The genomic analysis of EuMV-Jal led to the discovery of a subgroup of SLCV clade viruses that contain in

  4. The 5’-tail of antisense RNAII of pMV158 plays a critical role in binding to the target mRNA and in translation inhibition of repB

    Full Text Available Rolling-circle replication of streptococcal plasmid pMV158 is controlled by the concerted action of two trans-acting elements, namely transcriptional repressor CopG and antisense RNAII that inhibit expression of the repB gene encoding the replication initiator protein. The pMV158-encoded antisense RNAII exerts its activity of replication control by inhibiting translation of the essential repB gene. RNAII is the smallest and simplest among the characterized antisense RNAs involved in control of plasmid replication. Structure analysis of RNAII revealed that it folds into an 8-bp-long stem containing a 1-nt bulge and closed by a 6-nt apical loop. This hairpin is flanked by a 17-nt-long single-stranded 5’-tail and an 8-nt-long 3’-terminal U-rich stretch. Here, the 3’ and 5’ regions of the 5’-tail of RNAII are shown to play a critical role in the binding to the target mRNA and in the inhibition of repB translation, respectively. In contrast, the apical loop of the single hairpin of RNAII plays a rather secondary role and the upper stem region hardly contributes to the binding or inhibition processes. The entire 5’-tail is required for efficient inhibition of repB translation, though only the 8-nt-long region adjacent to the hairpin seems to be essential for rapid binding to the mRNA. These results show that a kissing interaction involving base-pairing between complementary hairpin loops in RNAII and mRNA is not critical for efficient RNA/RNA binding or repB translation inhibition. A singular binding mechanism is envisaged whereby initial pairing between complementary single-stranded regions in the antisense and sense RNAs progresses upwards into the corresponding hairpin stems to form the intermolecular duplex.

Pour essayer de saisir la logique des comportements dans l’espace et dans le social, j’ai participé à trois reprises au pèlerinage et j’ai réalisé un film. Ces moments précis de l’enquête ont contribué à définir mon expérience ethnographique et notamment mon intégration dans le village.

How do interior design students learn to imagine the occupants of the built environments they design? The concept of empathy, commonly defined as the capacity of identification with and understanding of another’s situation, feelings, and motives, is particularly suitable to explore this attitude. This paper has two parts. The first one presents an interior design academic exercise where students learn to imagine the occupants of their design project by using a methodological tool called an “ethical compass”. The compass is composed of three poles, which remind the three fundamental rela- tions in the human condition as they were considered in the Stoic tradition: man’s relation to oneself, to others, and to nature. In the second part, the paper outlines several theoretical elements, which help to understand, to strengthen, and eventually to make progress about some of the conceptual bases that underline this approach. Mainly, it outlines important ethical theories and specific approaches to the concept of empathy.RÉSUMÉLes professionnels ont par définition un public bénéficiaire de leurs services : le patient pour le médecin, le psychologue ou l’infirmière ; le client pour l’avocat ; le consommateur pour le ges- tionnaire d’une entreprise commerciale ; etc. L’usager ou l’habitant du cadre bâti constitue un des destinataires des services professionnels du designer d’intérieur.

Pourtant, depuis peu, cette périphérie présente le paradoxe d’un développement accéléré qui la singularise des autres provinces intérieures de la Chine par son premier rand pour son IDH et son PIB. Cette évolution s’explique par son rôle géostratégique dû à sa richesse en ressources naturelles et à sa position frontalière ce qui lui confère la fonction de « tête de pont » commerciale de la Chine en Asie centrale. L’achèvement du réseau routier et ferroviaire transcontinental porteur de migrations Han participe de la politique nationale de sécurisation et d’intégration économique et culturelle du Xinjiang ce que traduit le rapide déclin des minorités nationales.This paper analyses recent geographic change in the Xinjiang Uygur Autonomous Region. Xinjiang plays a geostratégic role in China due to abundance of natural resources such as oil, gas an coal but also for its particular geographic location in the heartland of Central Asia. The area gives to China an high potentiel for trade with the newly independent Central Asian republics and Eurasia. That’s the reason why central government take active measures for an acceleration of the economic development in the region with the aim of promoting regional security, cultural and économic integration.

    The application of soil conservation programs to combat erosion and sedimentation are significantly contributing to the protection of the natural resources. Watershed management practices include the assessment of Physical-Geographical, Climate, Geological, Pedological characteristics, including the analysis of Land Use of the regions concerned. The policy makers are increasingly looking for the different land uses and climatic scenarios that can be used for valuable projections for watershed management. To increase knowledge about those processes, use of hydrological and soil erosion models is needed and that is allowing quantification of soil redistribution and sediment productions. We focused on soil erosion processes in one of Northern Montenegrin mountain watersheds, the Novsicki Potok Watershed of the Polimlje River Basin, using modeling techniques: the IntErO model for calculation of runoff and soil loss. The model outcomes were validated through measurements of lake sediment deposition at the Potpec hydropower plant dam. Our findings indicate a medium potential of soil erosion risk. With 464 m³ yr-1 of annual sediment yield, corresponding to an area-specific sediment yield of 270 m³km-2 yr-1, the Novsicki Potok drainage basin belongs to the Montenegrin basins with the medium sediment discharge; according to the erosion type, it is surface erosion. The value of the Z coefficient was calculated on 0.403, what indicates that the river basin belongs to 3rd destruction category (of five). Our results suggest that the calculated peak discharge from the river basin was 82 m3s-1 for the incidence of 100 years. According to our analysis there is a possibility for large flood waves to appear in the studied river basin. With this research we, to some extent, improved the knowledge on the status of sediment yield and runoff of the river basins of Montenegro, where the map of Soil erosion is still not prepared.

    Full Text Available No presente artigo pretendemos descortinar as relações entre os elementos fantásticos na obra A República 3000, do escritor Menotti del Picchia. Primeiramente iremos realizar uma breve recapitulação de alguns aspectos da literatura fantástica no Brasil. Posteriormente faremos recortes textuais, objetivando assim discutir aqueles que aproximem a linguagem com o universo fantástico. Tomaremos como referencial teórico os estudos de autores como Todorov e Carvalho. Também teceremos considerações sobre o comportamento do leitor diante dessa obra ímpar.This article aims to scrutinize the relationship of the fantastic elements in Menotti del Picchia’s work A República 3000. Firstly, we will briefly look at some aspects inherent to the Fantastic Literature in Brazil. Then we will select some excerpts whose language are closely related to the fantastic world. The theoretical framework draws on Todorov and Carvalho. We will also consider the possible reader’s degree of behavior in relation to the aforementioned masterpiece.

    Full Text Available Le présent article se focalise sur le développement d'outils de traitement automatique des langues (TAL pour l'apprentissage des langues assisté par ordinateur (ALAO. Après avoir identifié les limitations inhérentes aux outils d'ALAO dépourvus de composantes TAL, nous décrivons le cadre général du projet MIRTO, une plateforme de création d'activités pédagogiques fondé sur des outils TAL en développement au sein de notre laboratoire. Cette plateforme est organisée en quatre couches distinctes et successives : fonctions, scripts, activités et scénarios. À travers plusieurs exemples, nous expliquons en quoi l'architecture de MIRTO permet l'implantation de fonctions TAL classiques au sein de scripts, lesquels facilitent la conception, sans compétence informatique préalable, d'activités didactiques, elles-mêmes éventuellement intégrées au sein de séquences plus complexes, ou scénarios.

    A screening of antimicrobial resistance and its genetic determinants has been performed on 300 Salmonella enterica isolates collected during 2004-2008 from human infections in Spain. Salmonella Typhimurium and Salmonella Enteritidis were the major serotypes, which were found with similar frequencies covering 80% of the bacterial collection. Salmonella Typhimurium isolates frequently shared low susceptibility to antimicrobials of the penta-resistance phenotype (ACSSuT) and/or cephalosporin resistance. The ACSSuT profile was found closely linked to int1-associated gene cassettes, with major elements carrying DNA fragments of 1.0 Kb (aadA2 gene) plus 1.2 Kb (blaPSE-1 gene) or 2.0 Kb (aadA1 and blaOXA-1 genes). Among these, ACSSuT and cephalosporin resistances were associated in Salmonella Typhimurium isolates expressing the blaOXA gene. β-lactamase activities were also detected from isolates carrying blaTEM, blaCMY, or blaSHV, although only the two last genes expressed extended-spectrum β-lactamases. The clonal analysis of S. enterica strains suggests that both horizontal and vertical transfer mechanisms are involved in the wide dissemination of their antimicrobial resistance.

  15. Traitement automatisé de la néologie : pourquoi et comment intégrer l'analyse thématique ?

    L’originalité du Logoscope le distingue des outils similaires existants : contrairement ces derniers, l’acquisition semi-automatisée des néologismes intègre d’emblée les conditions textuelles et discursives de l’innovation lexicale. Cette direction de recherche est en effet essentielle : dans le domaine de la néologie, tout ce que nous savons déjà de la morphologie d’une langue et des types de formation des mots devrait être complété par une description des conditions de production et de réception des néologismes, étant donné qu’aucune création lexicale ne se produit jamais en dehors d’un texte particulier et d’une situation de communication définie. Pratiquement, nous proposons donc un outil d’acquisition et une ressource néologique qui documente non seulement les néologismes au moyen des variables traditionnelles (morphologie, formation du mot, parties du discours, etc., mais aussi au moyen de variables chargées de décrire dans quel contexte communicationnel précis ils apparaissent.

    Background T cell-mediated liver damage is a key event in the pathogenesis of many chronic human liver diseases, such as liver transplant rejection, primary biliary cirrhosis, and sclerosing cholangitis. We and other groups have previously reported that galectin-9, one of the β-galactoside binding animal lectins, might be potentially useful in the treatment of T cell-mediated diseases. To evaluate the direct effect of galectin-9 on hepatitis induced by concanavalin A (Con A) administration in mice and to clarify the mechanisms involved, we administered galectin-9 into mice, and evaluated its therapeutic effect on Con A-induced hepatitis. Methodology/Principal Findings Galectin-9 was administrated i.v. to Balb/c mice 30 min before Con A injection. Compared with no treatment, galectin-9 pretreatment significantly reduced serum ALT and AST levels and improved liver histopathology, suggesting an ameliorated hepatitis. This therapeutic effect was not only attributable to a blunted Th1 immune response, but also to an increased number in regulatory T cells, as reflected in a significantly increased apoptosis of CD4+CD25low/int effector T cells and in reduced proinflammatory cytokine levels. Conclusion/Significance Our findings constitute the first preclinical data indicating that interfering with TIM-3/galectin-9 signaling in vivo could ameliorate Con A-induced hepatitis. This strategy may represent a new therapeutic approach in treating human diseases involving T cell activation. PMID:23118999

    Full Text Available o presente trabalho, tem como objetivo discutir e analisar trajetórias, atuações e relações de ensino em que temos presente a figura do intérprete de língua de sinais educacional incluído na dinâmica escolar: sua emergência na escola, os discursos sobre sua função e as práticas decorrentes de sua atuação tradutória cotidiana - as implicações que há no ensino de surdos, os modos como se entende tal função. A tese tem como objetivo teorízar e afirmar pelo menos três modos de mestria presentes em variadas salas de aula, especificamente nas que contam com a presença de pessoas surdas e de intérpretes de língua de sinais educacional. Os modos são os seguintes: o mestre explicador, o revelador e o emissor de signos. Em cada análise, faço um aprofundamento das possíveis relações interpessoais entre os sujeitos em dada cena, sendo, portanto, relações de docência a partir dessas proposições. O olhar se dá nos espaços propostos e configurados a partir de uma relação docente, e com isso, as análises realizadas passam pelo olhar conceitual de Michel Foucault, tendo como marca as relações de subjetividades no ocidente. Para tal empreitada, buscaram-se, nos estudos foucaultianos os tipos de mestria possíveis, apresentados pelo autor na obra A hermenêutica do sujeito. Isso se fez para afirmar a necessidade de um retorno a uma relação antiga de ensino: um mestre que se ocupa com o processo e não com o yroduto; uma mestria que se faz não pela condução ao modelo, mas na presença do "estar com o outro". Assim, conceitos de Gilles Deleuze e Michel Foucault são trazidos e combinados entre si para complementar o que se afirma como mestria ativa, ou seja, uma posição-mestre, que possibilita efeito de relações parresiásticas de ensino. A posição-mestre será baliza da pela relação conceitual existente entre ela e a função-educador - conceito desenvolvido na tese de doutoramento de Carvalho (2008. Nesse

    Full Text Available All IV iron complexes carry a risk of potentially fatal allergic type hypersensitivity reactions. The mechanism(s behind these reactions is unknown but the limited data available suggests that classic IgE mediated allergy is exceedingly rare, if ever occurring. Iron–carbohydrate molecules are complex nano-particles and trying to reduce the risk of serious hypersensitivity to antibody binding of an artificial antibody seems meaningless. A recently published analysis of safety data from randomized clinical trials confirms the method reported by Neiser to be useless to predict reaction risk. In conclusion, the study by Neiser et al. is biased, contains no new information, and has no clinical relevance. We are concerned that the association of the authors with a commercial entity has caused a conflict of interest that biases not only the results, but the entire experimental setup against competitors.

    Full Text Available Le Maghreb central (Maroc, Algérie, Tunisie possède une façade maritime de 3 000 km en bordure de la mer Méditerranée et de l’océan Atlantique. Sa position de carrefour entre deux mers et deux continents en fait un acteur stratégique de l’interface Nord/Sud que constitue la mer Méditerranée. Les auteurs passent ici en revue les éléments de convergence et de divergence dans l’organisation spatiale de cette façade et analysent le rôle des ports et du transport maritime dans la mise en relation régionale et mondiale des espaces du Maghreb. Malgré le rôle-clé des ports dans l’économie régionale, la croissance du trafic et l’élargissement géographique des avant-pays maritimes, l’intégration territoriale de cette région reste limitée.
