2006-10-01

Full Text Available Abstract With the decreasing cost of DNA sequencing technology and the vast diversity of biological resources, researchers increasingly face the basic challenge of annotating a larger number of expressed sequences tags (EST from a variety of species. This typically consists of a series of repetitive tasks, which should be automated and easy to use. The results of these annotation tasks need to be stored and organized in a consistent way. All these operations should be self-installing, platform independent, easy to customize and amenable to using distributed bioinformatics resources available on the Internet. In order to address these issues, we present EST-PAC a web oriented multi-platform software package for expressed sequences tag (EST annotation. EST-PAC provides a solution for the administration of EST and protein sequence annotations accessible through a web interface. Three aspects of EST annotation are automated: 1 searching local or remote biological databases for sequence similarities using Blast services, 2 predicting protein coding sequence from EST data and, 3 annotating predicted protein sequences with functional domain predictions. In practice, EST-PAC integrates the BLASTALL suite, EST-Scan2 and HMMER in a relational database system accessible through a simple web interface. EST-PAC also takes advantage of the relational database to allow consistent storage, powerful queries of results and, management of the annotation process. The system allows users to customize annotation strategies and provides an open-source data-management environment for research and education in bioinformatics.

Crystal structure of hyperthermophilic esterase EstE1 and the relationship between its dimerization and thermostability properties

Directory of Open Access Journals (Sweden)

Koh Eunhee

2007-07-01

Full Text Available Abstract Background EstE1 is a hyperthermophilic esterase belonging to the hormone-sensitive lipase family and was originally isolated by functional screening of a metagenomic library constructed from a thermal environmental sample. Dimers and oligomers may have been evolutionally selected in thermophiles because intersubunit interactions can confer thermostability on the proteins. The molecular mechanisms of thermostabilization of this extremely thermostable esterase are not well understood due to the lack of structural information. Results Here we report for the first time the 2.1-Å resolution crystal structure of EstE1. The three-dimensional structure of EstE1 exhibits a classic α/β hydrolase fold with a central parallel-stranded beta sheet surrounded by alpha helices on both sides. The residues Ser154, Asp251, and His281 form the catalytic triad motif commonly found in other α/β hydrolases. EstE1 exists as a dimer that is formed by hydrophobic interactions and salt bridges. Circular dichroism spectroscopy and heat inactivation kinetic analysis of EstE1 mutants, which were generated by structure-based site-directed mutagenesis of amino acid residues participating in EstE1 dimerization, revealed that hydrophobic interactions through Val274 and Phe276 on the β8 strand of each monomer play a major role in the dimerization of EstE1. In contrast, the intermolecular salt bridges contribute less significantly to the dimerization and thermostability of EstE1. Conclusion Our results suggest that intermolecular hydrophobic interactions are essential for the hyperthermostability of EstE1. The molecular mechanism that allows EstE1 to endure high temperature will provide guideline for rational design of a thermostable esterase/lipase using the lipolytic enzymes showing structural similarity to EstE1.

Forty-one markers from both Phalaenopsis and Dendrobium thatamplified in Dendrobium were assessed on six commercial cultivars and six wild accessions. All of them were transferableamong Dendrobium species. High polymorphism and heterozygosity were observed within wild accessions. Sixteen polymorphic markers were evaluated for linkage analysis on an F1 segregating population. Seven markers were mapped into threelinkage groups, two of which showed syntenic relationship between dendrobium and rice. This relationship will facilitatefurther quantitative trait loci (QTL mapping and comparative genomic studies of Dendrobium.

With the advent of low-cost, high-throughput sequencing, the amount of public domain Expressed Sequence Tag (EST) sequence data available for both model and non-model organism is growing exponentially. While these data are widely used for characterizing various genomes, they also present a serious challenge for data quality control and validation due to their inherent deficiencies, particularly for species without genome sequences. ConiferEST is an integrated system for data reprocessing, visualization and mining of conifer ESTs. In its current release, Build 1.0, it houses 172,229 loblolly pine EST sequence reads, which were obtained from reprocessing raw DNA sequencer traces using our software--WebTraceMiner. The trace files were downloaded from NCBI Trace Archive. ConiferEST provides biologists unique, easy-to-use data visualization and mining tools for a variety of putative sequence features including cloning vector segments, adapter sequences, restriction endonuclease recognition sites, polyA and polyT runs, and their corresponding Phred quality values. Based on these putative features, verified sequence features such as 3' and/or 5' termini of cDNA inserts in either sense or non-sense strand have been identified in-silico. Interestingly, only 30.03% of the designated 3' ESTs were found to have an authenticated 5' terminus in the non-sense strand (i.e., polyT tails), while fewer than 5.34% of the designated 5' ESTs had a verified 5' terminus in the sense strand. Such previously ignored features provide valuable insight for data quality control and validation of error-prone ESTs, as well as the ability to identify novel functional motifs embedded in large EST datasets. We found that "double-termini adapters" were effective indicators of potential EST chimeras. For all sequences with in-silico verified termini/terminus, we used InterProScan to assign protein domain signatures, results of which are available for in-depth exploration using our biologist

Full Text Available This study aims at contributing to the investigation on the instruction of EST (English for Science and Technology vocabulary, in terms of receptive use of the language. It evaluates the effectiveness of two teaching approaches to the acquisition of vocabulary. The first approach consisted of teaching vocabulary through the use of dictionaries, where the words were merely translated into the learners’ L1 or defined in the target language thus promoting superficial level of word processing. The second approach employed activities promoting deep level of word processing. Data were analysed quantitatively. Results indicated that the two approaches seem to have some equipotentiality, as far as EST vocabulary is concerned.

Biochemical and Structural Analysis of Hormone-sensitive Lipase Homolog EstE7: Insight into the Stabilized Dimerization of HSL-Homolog Proteins

International Nuclear Information System (INIS)

Nam, Ki Hyun; Park, Sung Ha; Lee, Won Ho; Hwang, Kwang Yeon

2010-01-01

Hormone sensitive lipase (HSL) plays a major role in energy homeostasis and lipid metabolism. Several crystal structures of HSL-homolog proteins have been identified, which has led to a better understanding of its molecular function. HSLhomolog proteins exit as both monomer and dimer, but the biochemical and structural basis for such oligomeric states has not been successfully elucidated. Therefore, we determined the crystal structure of HSL-homolog protein EstE7 from a metagenome library at 2.2 A resolution and characterized the oligomeric states of EstE7 both structurally and biochemically. EstE7 protein prefers the dimeric state in solution, which is supported by its higher enzymatic activity in the dimeric state. In the crystal form, EstE7 protein shows two-types of dimeric interface. Specifically, dimerization via the external β8-strand occurred through tight association between two pseudosymmetric folds via salt bridges, hydrogen bonds and van der Waals interactions. This dimer formation was similar to that of other HSL-homolog protein structures such as AFEST, BEFA, and EstE1. We anticipate that our results will provide insight into the oligomeric state of HSLhomolog proteins

2010-12-01

Full Text Available Abstract Background The castor bean (Ricinus communis L., a monotypic species in the spurge family (Euphorbiaceae, 2n = 20, is an important non-edible oilseed crop widely cultivated in tropical, sub-tropical and temperate countries for its high economic value. Because of the high level of ricinoleic acid (over 85% in its seed oil, the castor bean seed derivatives are often used in aviation oil, lubricants, nylon, dyes, inks, soaps, adhesive and biodiesel. Due to lack of efficient molecular markers, little is known about the population genetic diversity and the genetic relationships among castor bean germplasm. Efficient and robust molecular markers are increasingly needed for breeding and improving varieties in castor bean. The advent of modern genomics has produced large amounts of publicly available DNA sequence data. In particular, expressed sequence tags (ESTs provide valuable resources to develop gene-associated SSR markers. Results In total, 18,928 publicly available non-redundant castor bean EST sequences, representing approximately 17.03 Mb, were evaluated and 7732 SSR sites in 5,122 ESTs were identified by data mining. Castor bean exhibited considerably high frequency of EST-SSRs. We developed and characterized 118 polymorphic EST-SSR markers from 379 primer pairs flanking repeats by screening 24 castor bean samples collected from different countries. A total of 350 alleles were identified from 118 polymorphic SSR loci, ranging from 2-6 per locus (A with an average of 2.97. The EST-SSR markers developed displayed moderate gene diversity (He with an average of 0.41. Genetic relationships among 24 germplasms were investigated using the genotypes of 350 alleles, showing geographic pattern of genotypes across genetic diversity centers of castor bean. Conclusion Castor bean EST sequences exhibited considerably high frequency of SSR sites, and were rich resources for developing EST-SSR markers. These EST-SSR markers would be particularly

Full Text Available Abstract Background New sequencing technologies are rapidly emerging. Many laboratories are simultaneously working with the traditional Sanger ESTs and experimenting with ESTs generated by the 454 Life Science sequencers. Though Sanger ESTs have been used to generate contigs for many years, no program takes full advantage of the 5' and 3' mate-pair information, hence, many tentative transcripts are assembled into two separate contigs. The new 454 technology has the benefit of high-throughput expression profiling, but introduces time and space problems for assembling large contigs. Results The PAVE (Program for Assembling and Viewing ESTs assembler takes advantage of the 5' and 3' mate-pair information by requiring that the mate-pairs be assembled into the same contig and joined by n's if the two sub-contigs do not overlap. It handles the depth of 454 data sets by "burying" similar ESTs during assembly, which retains the expression level information while circumventing time and space problems. PAVE uses MegaBLAST for the clustering step and CAP3 for assembly, however it assembles incrementally to enforce the mate-pair constraint, bury ESTs, and reduce incorrect joins and splits. The PAVE data management system uses a MySQL database to store multiple libraries of ESTs along with their metadata; the management system allows multiple assemblies with variations on libraries and parameters. Analysis routines provide standard annotation for the contigs including a measure of differentially expressed genes across the libraries. A Java viewer program is provided for display and analysis of the results. Our results clearly show the benefit of using the PAVE assembler to explicitly use mate-pair information and bury ESTs for large contigs. Conclusion The PAVE assembler provides a software package for assembling Sanger and/or 454 ESTs. The assembly software, data management software, Java viewer and user's guide are freely available.

Several biological techniques result in the acquisition of functional sets of cDNAs that must be sequenced and analyzed. The emergence of redundant databases such as UniGene and centralized annotation engines such as Entrez Gene has allowed the development of software that can analyze a great number of sequences in a matter of seconds. We have developed "EST Express", a suite of analytical tools that identify and annotate ESTs originating from specific mRNA populations. The software consists of a user-friendly GUI powered by PHP and MySQL that allows for online collaboration between researchers and continuity with UniGene, Entrez Gene and RefSeq. Two key features of the software include a novel, simplified Entrez Gene parser and tools to manage cDNA library sequencing projects. We have tested the software on a large data set (2,016 samples) produced by subtractive hybridization. EST Express is an open-source, cross-platform web server application that imports sequences from cDNA libraries, such as those generated through subtractive hybridization or yeast two-hybrid screens. It then provides several layers of annotation based on Entrez Gene and RefSeq to allow the user to highlight useful genes and manage cDNA library projects.

Recombinant EstE1 protein with a histidine tag at the C-terminus was overexpressed in Escherichia coli strain BL21(DE3) and then purified by affinity chromatography. The protein was then crystallized at 290 K by the hanging-drop vapour-diffusion method. EstE1, a new thermostable esterase, was isolated by functional screening of a metagenomic DNA library from thermal environment samples. This enzyme showed activity towards short-chain acyl derivatives of length C4–C6 at a temperature of 303–363 K and displayed a high thermostability above 353 K. EstE1 has 64 and 57% amino-acid sequence similarity to est{sub pc}-encoded carboxylesterase from Pyrobaculum calidifontis and AFEST from Archaeoglobus fulgidus, respectively. The recombinant protein with a histidine tag at the C-terminus was overexpressed in Escherichia coli strain BL21(DE3) and then purified by affinity chromatography. The protein was crystallized at 290 K by the hanging-drop vapour-diffusion method. X-ray diffraction data were collected to 2.3 Å resolution from an EstE1 crystal; the crystal belongs to space group P4{sub 1}2{sub 1}2, with unit-cell parameters a = b = 73.71, c = 234.23 Å. Assuming the presence of four molecules in the asymmetric unit, the Matthews coefficient V{sub M} is calculated to be 2.2 Å{sup 3} Da{sup −1} and the solvent content is 44.1%.

Full Text Available Mapping expressed sequence tags (ESTs to hexaploid wheat is aimed to reveal the structure and function of the hexaploid wheat genome. Sixty eight ESTs representing 26 genes were mapped into all seven homologous chromosome groups of wheat (Triticum aestivum L using a polymerase chain reaction technique. The majority of the ESTs were mapped to homologous chromosome group 2, and the least were mapped to homologous chromosome group 6. Comparative analysis between the EST map from this study and the EST map based on RFLPs showed 14 genes that have been mapped by both approaches were mapped to the same arm of the same homologous chromosome, which indicated that using PCR-based ESTs was a reliable approach in mapping ESTs in hexaploid wheat.

Full Text Available In order to obtain a better understanding of what is citrus, 33 cDNA libraries were constructed from different citrus species and genera. Total RNA was extracted from fruits, leaves, flowers, bark, seeds and roots, and subjected or not to different biotic and abiotic stresses (pathogens and drought and at several developmental stages. To identify putative promoter sequences, as well as molecular markers that could be useful for breeding programs, one shotgun library was prepared from sweet orange (Citrus sinensis var. Olimpia. In addition, EST libraries were also constructed for a citrus pathogen, the oomycete Phythophthora parasitica in either virulent or avirulent form. A total of 286,559 cDNA clones from citrus were sequenced from their 5’ end, generating 242,790 valid reads of citrus. A total of 9,504 sequences were produced in the shotgun library and the valid reads were assembled using CAP3. In this procedure, we obtained 1,131 contigs and 4,083 singletons. A total of 19,200 cDNA clones from P. parasitica were sequenced, resulting in 16,400 valid reads. The number of ESTs generated in this project is, to our knowledge, the largest citrus sequence database in the world.

Aproximaciones a una estética de lo americano

Full Text Available El legado filosófico que nos ha dejado Rodolfo Kusch tiene cada vez más presencia y valor en este largo itinerario de descubrirnos como americanos. La pasión de este pensador por la América profunda es una fuente de ins- piración para quienes creemos que vivir en América no es simplemente un episodio geográfico sino un horizonte desde y a partir del cual construimos nuestra identidad. En este trabajo se pretende recrear sus consideracio - nes estéticas recogidas en su ensayo “Anotaciones para una estética de lo americano”, escrito en el año 1955. Aunque se trata de uno de los primeros escritos de Rodolfo Kusch, en el mismo se encuentran presentes numerosos conceptos que luego serán tematizados extensamente a lo largo de toda su obra. Considero que el abordaje a sus consideraciones estéticas no ha sido tan frecuentado como sí otros aspectos de su pensamiento (ser-estar, geocultura, símbolo y religión, etc.. Por ello, creo que este trabajo puede constituir una orientación preeliminar para futuras interpretaciones y, a la vez, ser un humilde homenaje a su filosofía, que, a lo largo de los años, sigue estimulando a antiguas y nuevas generaciones de pensadores dedicados a la filosofía latinoamericana.

Simple sequence repeats (SSRs) have become widely used as molecular markers in plant genetic studies due to their abundance, high allelic variation at each locus and simplicity to analyze using conventional PCR amplification. To study plants with unknown genome sequence, SSR markers from Expressed Sequence Tags (ESTs), which can be obtained from the plant mRNA (converted to cDNA), must be utilized. With the advent of high-throughput sequencing technology, huge EST sequence data have been generated and are now accessible from many public databases. However, SSR marker identification from a large in-house or public EST collection requires a computational pipeline that makes use of several standard bioinformatic tools to design high quality EST-SSR primers. Some of these computational tools are not users friendly and must be tightly integrated with reference genomic databases. A web-based bioinformatic pipeline, called EST Analysis Pipeline Plus (ESAP Plus), was constructed for assisting researchers to develop SSR markers from a large EST collection. ESAP Plus incorporates several bioinformatic scripts and some useful standard software tools necessary for the four main procedures of EST-SSR marker development, namely 1) pre-processing, 2) clustering and assembly, 3) SSR mining and 4) SSR primer design. The proposed pipeline also provides two alternative steps for reducing EST redundancy and identifying SSR loci. Using public sugarcane ESTs, ESAP Plus automatically executed the aforementioned computational pipeline via a simple web user interface, which was implemented using standard PHP, HTML, CSS and Java scripts. With ESAP Plus, users can upload raw EST data and choose various filtering options and parameters to analyze each of the four main procedures through this web interface. All input EST data and their predicted SSR results will be stored in the ESAP Plus MySQL database. Users will be notified via e-mail when the automatic process is completed and they can

2006-06-01

Full Text Available Abstract Background Wheat is an excellent species to study freezing tolerance and other abiotic stresses. However, the sequence of the wheat genome has not been completely characterized due to its complexity and large size. To circumvent this obstacle and identify genes involved in cold acclimation and associated stresses, a large scale EST sequencing approach was undertaken by the Functional Genomics of Abiotic Stress (FGAS project. Results We generated 73,521 quality-filtered ESTs from eleven cDNA libraries constructed from wheat plants exposed to various abiotic stresses and at different developmental stages. In addition, 196,041 ESTs for which tracefiles were available from the National Science Foundation wheat EST sequencing program and DuPont were also quality-filtered and used in the analysis. Clustering of the combined ESTs with d2_cluster and TGICL yielded a few large clusters containing several thousand ESTs that were refractory to routine clustering techniques. To resolve this problem, the sequence proximity and "bridges" were identified by an e-value distance graph to manually break clusters into smaller groups. Assembly of the resolved ESTs generated a 75,488 unique sequence set (31,580 contigs and 43,908 singletons/singlets. Digital expression analyses indicated that the FGAS dataset is enriched in stress-regulated genes compared to the other public datasets. Over 43% of the unique sequence set was annotated and classified into functional categories according to Gene Ontology. Conclusion We have annotated 29,556 different sequences, an almost 5-fold increase in annotated sequences compared to the available wheat public databases. Digital expression analysis combined with gene annotation helped in the identification of several pathways associated with abiotic stress. The genomic resources and knowledge developed by this project will contribute to a better understanding of the different mechanisms that govern stress tolerance in

Rapid in silico cloning of genes using expressed sequence tags (ESTs).

Expressed sequence tags (ESTs) are short single-pass DNA sequences obtained from either end of cDNA clones. These ESTs are derived from a vast number of cDNA libraries obtained from different species. Human ESTs are the bulk of the data and have been widely used to identify new members of gene families, as markers on the human chromosomes, to discover polymorphism sites and to compare expression patterns in different tissues or pathologies states. Information strategies have been devised to query EST databases. Since most of the analysis is performed with a computer, the term "in silico" strategy has been coined. In this chapter we will review the current status of EST databases, the pros and cons of EST-type data and describe possible strategies to retrieve meaningful information.

Full Text Available Este artículo describe la experiencia estética como un fenómeno centrado en la percepción sensorial. El trabajo se desarrolla a partir de una investigación de la psicología social basado en la fenomenología, sobre todo en los planteamientos de Merleau-Ponty y Dufrenne. Concibe la experiencia estética como un modo de relación mediada por la percepción sensorial de un objeto estético. Se analizan diversos aspectos de la experiencia estética: la dimensión relacional y sensible; ¿cómo se constituye el sujeto y el objeto estético; la dimensión corporal de la experiencia estética; la intencionalidad en la estética; la experiencia estética de la naturaleza. Llegamos a la conclusión de que hay un significado ontológico de la experiencia estética, ya que proporciona una apertura a la diferencia por el contacto con la alteridad, y una nueva mirada a la realidad. Se destaca al final la relevancia de esta experiencia a la Psicología Social.

Single-pass, partial sequencing of complementary DNA (cDNA) libraries generates thousands of chromatograms that are processed into high quality expressed sequence tags (ESTs), and then assembled into contigs representative of putative genes. Usually, to be of value, ESTs and contigs must be associated with meaningful annotations, and made available to end-users. A web application, Expressed Sequence Tag Information Management and Annotation (ESTIMA), has been created to meet the EST annotation and data management requirements of multiple high-throughput EST sequencing projects. It is anchored on individual ESTs and organized around different properties of ESTs including chromatograms, base-calling quality scores, structure of assembled transcripts, and multiple sources of comparison to infer functional annotation, Gene Ontology associations, and cDNA library information. ESTIMA consists of a relational database schema and a set of interactive query interfaces. These are integrated with a suite of web-based tools that allow a user to query and retrieve information. Further, query results are interconnected among the various EST properties. ESTIMA has several unique features. Users may run their own EST processing pipeline, search against preferred reference genomes, and use any clustering and assembly algorithm. The ESTIMA database schema is very flexible and accepts output from any EST processing and assembly pipeline. ESTIMA has been used for the management of EST projects of many species, including honeybee (Apis mellifera), cattle (Bos taurus), songbird (Taeniopygia guttata), corn rootworm (Diabrotica vergifera), catfish (Ictalurus punctatus, Ictalurus furcatus), and apple (Malus x domestica). The entire resource may be downloaded and used as is, or readily adapted to fit the unique needs of other cDNA sequencing projects.

The ESTE system (Emergency Source Term Evaluation) is support instrument for off-site emergency response and its main objective is to assist to the crisis staff: - to mitigate radiological consequences of significant releases; - to manage the protective measures; - to manage emergency monitoring. At national level the ESTE system are implemented at the Emergency Response Centre of the Czech Republic (SUJB) and Austrian versions are implemented at the Crisis Centre of the Austrian Republic (BMLFUW).

Full Text Available La reflexión filosófica sobre el arte, lo hermoso, lo bueno, lo verdadero y su capacidad de promover el desarrollo humano es un tema que remonta a Platón en la cultura occidental. Considerando que la educación debe ser entendida como un fenómeno integral, que abarca no sólo las dimensiones intelectuales sino también las dimensiones sensibles, la intuición y el raciocinio, las capacidades imaginativas y creativas, el «saber ser» y el «saber estar» parejas del «conocer» y del «saber hacer», pensamos que es incuestionable la importancia de la estética en el fenómeno educativo. El objetivo de este trabajo es demostrar la importancia de la educación estética como motor fundamental de desarrollo humano y, en este sentido, como catalizador de la motivación y del aprendizaje, para que, a través de la imaginación y de la creatividad, sea posible la innovación en la construcción de vías alternativas para un mundo más humano y placentero.

Full Text Available La estética facial asociada con los dientes ha preocupado a la sociedad desde la antigüedad. El temor al rechazo social por cambios de forma, color o posiciones dentales, puede producir un gran impacto psicológico en los pacientes. Con el objetivo de valorar la repercusión psicosocial de las alteraciones estéticas faciales, de determinar el nivel de prioridad que ocupan los tratamientos estéticos dentales y demostrar así la necesidad de intensificar nuestra labor educativa encaminada a evitar aquellas afecciones estéticas que más inciden en nuestra población, procedimos a la aplicación de una encuesta anónima en 110 pacientes que acudieron al Servicio de Estomatología Integral de la Facultad de Estomatología entre noviembre de 1999 y abril del 2000. Se recogió información sobre: actitud asumida por pacientes afectados, prioridades de tratamientos, etcétera. Dicha información fue procesada en tablas estadísticas. Los resultados del trabajo nos permiten concluir que las afecciones estéticas dentales tienen gran repercusión psicosocial, lo que unido al haber encontrado las lesiones traumáticas como las afecciones estéticas de mayor prevalencia, nos evidencia la necesidad de enfatizar nuestra labor educativa en este aspecto.Society has worried about facial esthetics associated with teeth since ancient times.

Two EST-derived marker systems for cultivar identification in tree peony.

Science.gov (United States)

Zhang, J J; Shu, Q Y; Liu, Z A; Ren, H X; Wang, L S; De Keyser, E

2012-02-01

Tree peony (Paeonia suffruticosa Andrews), a woody deciduous shrub, belongs to the section Moutan DC. in the genus of Paeonia of the Paeoniaceae family. To increase the efficiency of breeding, two EST-derived marker systems were developed based on a tree peony expressed sequence tag (EST) database. Using target region amplification polymorphism (TRAP), 19 of 39 primer pairs showed good amplification for 56 accessions with amplicons ranging from 120 to 3,000 bp long, among which 99.3% were polymorphic. In contrast, 7 of 21 primer pairs demonstrated adequate amplification with clear bands for simple sequence repeats (SSRs) developed from ESTs, and a total of 33 alleles were found in 56 accessions. The similarity matrices generated by TRAP and EST-SSR markers were compared, and the Mantel test (r = 0.57778, P = 0.0020) showed a moderate correlation between the two types of molecular markers. TRAP markers were suitable for DNA fingerprinting and EST-SSR markers were more appropriate for discriminating synonyms (the same cultivars with different names due to limited information exchanged among different geographic areas). The two sets of EST-derived markers will be used further for genetic linkage map construction and quantitative trait locus detection in tree peony.

Yumurtaci, Aysen; Sipahi, Hulya; Al-Abdallat, Ayed; Jighly, Abdulqader; Baum, Michael

2017-06-01

Surveying Fusarium resistance in wheat with easy applicable molecular markers such as simple sequence repeats (SSRs) is a prerequest for molecular breeding. Expressed sequence tags (ESTs) are one of the main sources for development of new SSR candidates. Therefore, 18.292 publicly available wheat ESTs were mined and genotyping of newly developed 55 EST-SSR derived primer pairs produced clear fragments in ten wheat cultivars carrying different levels of Fusarium resistance. Among the proved markers, 23 polymorphic EST-SSRs were obtained and related alleles were mostly found on B and D genome. Based on the fragment profiling and similarity analysis, a 327bp amplicon, which was a product of contig 1207 (chromosome 5BL), was detected only in Fusarium head blight (FHB) resistant cultivars (CM82036 and Sumai) and the amino acid sequences showed a similarity to pathogen related proteins. Another FHB resistance related EST-SSR, Contig 556 (chromosome 1BL) produced a 151bp fragment in Sumai and was associated to wax2-like protein. A polymorphic 204bp fragment, derived from Contig 578 (chromosome 1DL), was generated from root rot (FRR) resistant cultivars (2-49; Altay2000 and Sunco). A total of 98 alleles were displayed with an average of 1.8 alleles per locus and the polymorphic information content (PIC) ranged from 0.11 to 0.78. Dendrogram tree with two main and five sub-groups were displayed the highest genetic relationship between FRR resistant cultivars (2-49 and Altay2000), FRR sensitive cultivars (Seri82 and Scout66) and FHB resistant cultivars (CM82036 and Sumai). Thus, exploitation of these candidate EST-SSRs may help to genotype other wheat sources for Fusarium resistance. Copyright © 2017 Elsevier Ltd. All rights reserved.

Development and production of an oligonucleotide MuscleChip: use for validation of ambiguous ESTs

Directory of Open Access Journals (Sweden)

Lanfranchi Gerolamo

2002-10-01

Full Text Available Abstract Background We describe the development, validation, and use of a highly redundant 120,000 oligonucleotide microarray (MuscleChip containing 4,601 probe sets representing 1,150 known genes expressed in muscle and 2,075 EST clusters from a non-normalized subtracted muscle EST sequencing project (28,074 EST sequences. This set included 369 novel EST clusters showing no match to previously characterized proteins in any database. Each probe set was designed to contain 20–32 25 mer oligonucleotides (10–16 paired perfect match and mismatch probe pairs per gene, with each probe evaluated for hybridization kinetics (Tm and similarity to other sequences. The 120,000 oligonucleotides were synthesized by photolithography and light-activated chemistry on each microarray. Results Hybridization of human muscle cRNAs to this MuscleChip (33 samples showed a correlation of 0.6 between the number of ESTs sequenced in each cluster and hybridization intensity. Out of 369 novel EST clusters not showing any similarity to previously characterized proteins, we focused on 250 EST clusters that were represented by robust probe sets on the MuscleChip fulfilling all stringent rules. 102 (41% were found to be consistently "present" by analysis of hybridization to human muscle RNA, of which 40 ESTs (39% could be genome anchored to potential transcription units in the human genome sequence. 19 ESTs of the 40 ESTs were furthermore computer-predicted as exons by one or more than three gene identification algorithms. Conclusion Our analysis found 40 transcriptionally validated, genome-anchored novel EST clusters to be expressed in human muscle. As most of these ESTs were low copy clusters (duplex and triplex in the original 28,000 EST project, the identification of these as significantly expressed is a robust validation of the transcript units that permits subsequent focus on the novel proteins encoded by these genes.

A atividade do designer de joias está atrelada aos estudos do mercado, da trajetória do belo, na sociedade, com o objetivo de encarnar na forma e sua essência no objeto estético. O conhecimento em profundidade sobre o belo e suas categorias estéticas seguem o seu tempo e mercado, permitindo ao designer liberar o caminho para o juízo crítico, a faculdade de pensar a forma, na fronteira entre teoria e prática, emoção e cálculo. A joia contemporânea reluz o belo, a técnica, a ideia, o imaginário. A estética contemporânea pondera a escassez de matéria-prima e os vários pensamentos que refletem na criação da forma. O conteúdo deste texto pincela brevemente a importância do conhecimento do designer no desenvolvimento de novas formas para atender às exigências do mercado.

Full Text Available Abstract Background There is no dedicated database available for Expressed Sequence Tags (EST of the chili pepper (Capsicum annuum, although the interest in a chili pepper EST database is increasing internationally due to the nutritional, economic, and pharmaceutical value of the plant. Recent advances in high-throughput sequencing of the ESTs of chili pepper cv. Bukang have produced hundreds of thousands of complementary DNA (cDNA sequences. Therefore, a chili pepper EST database was designed and constructed to enable comprehensive analysis of chili pepper gene expression in response to biotic and abiotic stresses. Results We built the Pepper EST database to mine the complexity of chili pepper ESTs. The database was built on 122,582 sequenced ESTs and 116,412 refined ESTs from 21 pepper EST libraries. The ESTs were clustered and assembled into virtual consensus cDNAs and the cDNAs were assigned to metabolic pathway, Gene Ontology (GO, and MIPS Functional Catalogue (FunCat. The Pepper EST database is designed to provide a workbench for (i identifying unigenes in pepper plants, (ii analyzing expression patterns in different developmental tissues and under conditions of stress, and (iii comparing the ESTs with those of other members of the Solanaceae family. The Pepper EST database is freely available at http://genepool.kribb.re.kr/pepper/. Conclusion The Pepper EST database is expected to provide a high-quality resource, which will contribute to gaining a systemic understanding of plant diseases and facilitate genetics-based population studies. The database is also expected to contribute to analysis of gene synteny as part of the chili pepper sequencing project by mapping ESTs to the genome.

Ju, Miao-Miao; Ma, Huan-Cheng; Xin, Pei-Yao; Zhou, Zhi-Li; Tian, Bin

2015-04-01

Bombax ceiba (Malvaceae), commonly known as silk cotton tree, is a multipurpose tree species of tropical forests. Novel expressed sequence tag-simple sequence repeat (EST-SSR) markers were developed and characterized for the species using transcriptome analysis. A total of 33 new EST-SSR markers were developed for B. ceiba, of which 13 showed polymorphisms across the 24 individuals from four distant populations tested in the study. The results showed that the number of alleles per polymorphic locus ranged from two to four, and the expected heterozygosity and observed heterozygosity per locus varied from 0.043 to 0.654 and from 0 to 0.609, respectively. These newly developed EST-SSR markers can be used in phylogeographic and population genetic studies to investigate the origin of B. ceiba populations. Furthermore, these EST-SSR markers could also greatly promote the development of molecular breeding studies pertaining to silk cotton tree.

Full Text Available La experiencia estética se constituye en un elemento crucial para la obra de John Dewey. En primer lugar, este pensador recupera la idea de experiencia, en sentido amplio, referida a los procesos conscientes realizados por el ser humano. En segundo lugar, esta experiencia aparece como resultado de la interacción de los hombres con su entorno, de tal modo que se amplían las valoraciones que aquellos tienen acerca de éste. En tercer lugar, la experiencia tiene elementos analíticos y sintéticos que posibilitan cualificar los procesos cognitivos y cognoscitivos de los individuos. En cuarto lugar, la experiencia se clasifica de acuerdo a su función en intelectual, práctica y estética, siendo la última la más importante, en tanto que, se muestra como más universal y ampliada frente a las otras, y se comporta como experiencia educativa al ser la que cualifica de manera más profunda los juicios críticos que se hacen frente al mundo.Los anteriores aspectos serán trabajados en este artículo, con miras a explorar la universalidad de la experiencia estética deweyana y sus derivaciones en el campo de una propuesta educativa, en la que resulta de vital importancia la existencia de una experiencia común entre los diferentes grupos humanos para lograr configurar la inteligencia común que es la base para la educación en John Dewey.

El artículo resalta la importancia de la sensibilidad en la actuación de los trabajadores sociales. Toma en cuenta tanto las sensaciones que recibimos nosotros como las que producimos en los demás. Desde esta perspectiva se abordan temas como la capacidad de observación, la inteligencia emocional, los estilos de vida, los estilos de trabajo, la resonancia, la sintonía con el cliente o el síndrome del profesional «quemado». Más aún, este ámbito de las sensaciones no está lejos del mundo teórico sino que es su punto de partida y su piedra de toque. En realidad, el mundo abstracto no existe sin el sensible. Y uno y otro tienen una dimensión relacional y ética. De este modo, el artículo termina criticando la separación de la ciencia, la estética y la ética como «esferas» de la cultura.

EVER-EST: European Virtual Environment for Research in Earth Science Themes

Science.gov (United States)

Glaves, H.; Albani, M.

2016-12-01

EVER-EST is an EC Horizon 2020 project having the goal to develop a Virtual Research Environment (VRE) providing a state-of-the-art solution to allow Earth Scientists to preserve their work and publications for reference and future reuse, and to share with others. The availability of such a solution, based on an innovative concept and state of art technology infrastructure, will considerably enhance the quality of how Earth Scientists work together within their own institution and also across other organizations, regions and countries. The concept of Research Objects (ROs), used in the Earth Sciences for the first time, will form the backbone of the EVER-EST VRE infrastructure. ROs will enhance the ability to preserve, re-use and share entire or individual parts of scientific workflows and all the resources related to a specific scientific investigation. These ROs will also potentially be used as part of the scholarly publication process. EVER-EST is building on technologies developed during almost 15 years of research on Earth Science data management infrastructures. The EVER-EST VRE Service Oriented Architecture is being meticulously designed to accommodate at best the requirements of a wide range of Earth Science communities and use cases: focus is put on common requirements and on minimising the level of complexity in the EVER-EST VRE to ensure future sustainability within the user communities beyond the end of the project. The EVER-EST VRE will be validated through its customisation and deployment by four Virtual Research Communities (VRCs) from different Earth Science disciplines and will support enhanced interaction between data providers and scientists in the Earth Science domain. User community will range from bio-marine researchers (Sea Monitoring use case), to common foreign and security policy institutions and stakeholders (Land Monitoring for Security use case), natural hazards forecasting systems (Natural Hazards use case), and disaster and risk

Construction of 12 EST libraries and characterization of a 12,226 EST dataset for chicory (Cichorium intybus root, leaves and nodules in the context of carbohydrate metabolism investigation

Directory of Open Access Journals (Sweden)

Boutry Marc

2009-01-01

Full Text Available Abstract Background The industrial chicory, Cichorium intybus, is a member of the Asteraceae family that accumulates fructan of the inulin type in its root. Inulin is a low calories sweetener, a texture agent and a health promoting ingredient due to its prebiotic properties. Average inulin chain length is a critical parameter that is genotype and temperature dependent. In the context of the study of carbohydrate metabolism and to get insight into the transcriptome of chicory root and to visualize temporal changes of gene expression during the growing season, we obtained and characterized 10 cDNA libraries from chicory roots regularly sampled in field during a growing season. A leaf and a nodule libraries were also obtained for comparison. Results Approximately 1,000 Expressed Sequence Tags (EST were obtained from each of twelve cDNA libraries resulting in a 12,226 EST dataset. Clustering of these ESTs returned 1,922 contigs and 4,869 singlets for a total of 6,791 putative unigenes. All ESTs were compared to public sequence databases and functionally classified. Data were specifically searched for sequences related to carbohydrate metabolism. Season wide evolution of functional classes was evaluated by comparing libraries at the level of functional categories and unigenes distribution. Conclusion This chicory EST dataset provides a season wide outlook of the genes expressed in the root and to a minor extent in leaves and nodules. The dataset contains more than 200 sequences related to carbohydrate metabolism and 3,500 new ESTs when compared to other recently released chicory EST datasets, probably because of the season wide coverage of the root samples. We believe that these sequences will contribute to accelerate research and breeding of the industrial chicory as well as of closely related species.

Expressed sequence tag (EST) markers have been used to assess variety and genetic diversity in wheat (Triticum aestivum). In this study, 1549 ESTs from wheat infested with yellow rust were used to examine the genetic diversity of six susceptible and resistant wheat cultivars. The aim of using these cultivars was to improve the competitiveness of public wheat breeding programs through the intensive use of modern, particularly marker-assisted, selection technologies. The F(2) individuals derived from cultivar crosses were screened for resistance to yellow rust at the seedling stage in greenhouses and adult stage in the field to identify DNA markers genetically linked to resistance. Five hundred and sixty ESTs were assembled into 136 contigs and 989 singletons. BlastX search results showed that 39 (29%) contigs and 96 (10%) singletons were homologous to wheat genes. The database-matched contigs and singletons were assigned to eight functional groups related to protein synthesis, photosynthesis, metabolism and energy, stress proteins, transporter proteins, protein breakdown and recycling, cell growth and division and reactive oxygen scavengers. PCR analyses with primers based on the contigs and singletons showed that the most polymorphic functional categories were photosynthesis (contigs) and metabolism and energy (singletons). EST analysis revealed considerable genetic variability among the Turkish wheat cultivars resistant and susceptible to yellow rust disease and allowed calculation of the mean genetic distance between cultivars, with the greatest similarity (0.725) being between Harmankaya99 and Sönmez2001, and the lowest (0.622) between Aytin98 and Izgi01.

Coevolution of cellular genetic compartments is a fundamental aspect in eukaryotic genome evolution that becomes apparent in serious developmental disturbances after interspecific organelle exchanges. The genus Oenothera represents a unique, at present the only available, resource to study the role of the compartmentalized plant genome in diversification of populations and speciation processes. An integrated approach involving cDNA cloning, EST sequencing, and bioinformatic data mining was chosen using Oenothera elata with the genetic constitution nuclear genome AA with plastome type I. The Gene Ontology system grouped 1621 unique gene products into 17 different functional categories. Application of arrays generated from a selected fraction of ESTs revealed significantly differing expression profiles among closely related Oenothera species possessing the potential to generate fertile and incompatible plastid/nuclear hybrids (hybrid bleaching). Furthermore, the EST library provides a valuable source of PCR-based polymorphic molecular markers that are instrumental for genotyping and molecular mapping approaches.

Full Text Available O objetivo deste experimento foi verificar o efeito do treino discriminativo sobre a formação de classes funcionais de melodias em andamentos e modos diferentes. Nove estudantes universitários do 2° período da graduação em Psicologia foram divididos em três grupos: Modo, Andamento ou Misto. O software SomPsi, produzido especialmente para este estudo, treinou os participantes e gerou relatórios com informações sobre os desempenhos, nas quatro fases do procedimento. O treino proposto mostrou-se eficiente para a formação das classes funcionais de estímulos sonoros musicais. Observou-se que agrupamentos de estímulos pela propriedade andamento foram mais facilmente discriminados que os agrupados pela melodia. A manipulação combinada das duas propriedades, em condição convergente, permitiu desempenho superior dos participantes. A rápida formação de classes funcionais e equivalentes de estímulos musicais, a partir de procedimentos de ensino automatizado de relações condicionais entre estímulos musicais, indica a possibilidade de uso desse procedimento na iniciação à música.

“OMNE, QUOD NON EST EX FIDE, PECCATUM EST" THE RELEVANCE OF GOOD FAITH IN CANONICAL TRANSACTIO

Sara Parini Vincenti

Full Text Available It is quite clear that there is a canonical foundation underlying the institute of transactio. Indeed, a compromise is often reached when a dispute has already entered the litigation phase, and as such legal doctrine tends to separate the economic aspect from the ethical aspect in its interpretation. Though the Church has a necessarily imperfect system of legal sanctions at its disposal, over the centuries it has in fact played a fundamental role in the ethical aspect of compromise. Indeed, the Gospel teaches that every human relationship must be based on concordia, as concordia mater est unitatis: if parties have ignored such morals and are about to litigate, or have already started legal proceedings, the Church must exhort them to settle the dispute. This article aims to examine the relevance of two of the essential requirements of transactio –namely lis and res dubia – within the Decretals (X 1.36. 1-11 de transactionibus. The framework of this analysis is provided by the tenet Effectus transactionis est, ut ei stetur, which sanctions the effectiveness of transactio as a juristic act. The goal is to evaluate how the uncertainty of legal proceedings relates to the principle of good faith in canon law.

Profiling studies of mRNA and miRNA, particularly microarray-based studies, have been extensively used to create compendia of genes that are preferentially expressed in the immune system. In some instances, functional studies have been subsequently pursued. Recent efforts such as ENCODE have demonstrated the benefit of coupling RNA-Seq analysis with information from expressed sequence tags (ESTs) for transcriptomic analysis. However, the full characterization and identification of transcripts that function as modulators of human immune responses remains incomplete. In this study, we demonstrate that an integrated analysis of human ESTs provides a robust platform to identify the immune transcriptome. Beyond recovering a reference set of immune-enriched genes and providing large-scale cross-validation of previous microarray studies, we discovered hundreds of novel genes preferentially expressed in the immune system, including non-coding RNAs. As a result, we have established the Immunogene database, representing an integrated EST “road map” of gene expression in human immune cells, which can be used to further investigate the function of coding and non-coding genes in the immune system. Using this approach, we have uncovered a unique metabolic gene signature of human macrophages and identified PRDM15 as a novel overexpressed gene in human lymphomas. Thus we demonstrate the utility of EST profiling as a basis for further deconstruction of physiologic and pathologic immune processes. PMID:23616578

2017-11-01

Full Text Available Identification of monokaryons and their mating types and discrimination of hybrid offspring are key steps for the crossbreeding of Pleurotus tuoliensis (Bailinggu. However, conventional crossbreeding methods are troublesome and time consuming. Using RNA-seq technology, we developed new expressed sequence tag-simple sequence repeat (EST-SSR markers for Bailinggu to easily and rapidly identify monokaryons and their mating types, genetic diversity and hybrid offspring. We identified 1110 potential EST-based SSR loci from a newly-sequenced Bailinggu transcriptome and then randomly selected 100 EST-SSRs for further validation. Results showed that 39, 43 and 34 novel EST-SSR markers successfully identified monokaryons from their parent dikaryons, differentiated two different mating types and discriminated F1 and F2 hybrid offspring, respectively. Furthermore, a total of 86 alleles were detected in 37 monokaryons using 18 highly informative EST-SSRs. The observed number of alleles per locus ranged from three to seven. Cluster analysis revealed that these monokaryons have a relatively high level of genetic diversity. Transfer rates of the EST-SSRs in the monokaryons of closely-related species Pleurotus eryngii var. ferulae and Pleurotus ostreatus were 72% and 64%, respectively. Therefore, our study provides new SSR markers and an efficient method to enhance the crossbreeding of Bailinggu and closely-related species.

Para tanto foi realizado um teste de discriminação de orientação entre duas barras apresentadas bilateralmente na periferia do campo visual (julgamento igual ou diferente. O grau de dificuldade da tarefa dependia da diferença de orientação das mesmas. Simultaneamente era apresentada uma figura central (neutra ou negativa entre as barras. Foi observado que as figuras negativas interferiram no desempenho dos voluntários mesmo na tarefa mais difícil, que exigia maior engajamento atencional. Além disto, quando o reconhecimento posterior destas figuras era testado, figuras negativas eram mais lembradas do que neutras. Estes dados sugerem que estímulos emocionais são privilegiados na disputa por recursos de atenção. É possível que esse privilégio ocorra devido a relevância destes estímulos, sendo dificilmente ignorados.

La metaphore est-elle la marque de l’insuffisance de l’esprit?

Isabelle Oliveira

2010-01-01

Full Text Available L’une des caractéristiques les plus communément reconnues à la discipline de la terminologie est sa conceptualité. Au contraire de l’opinion émise sur la métaphore, la terminologie s’efforce de travailler à partir de notions précises dont le sens doit être délimité et l’articulation à d’autres notions explicitée afin de bannir les ambiguïtés et les fausses évidences qu’elles véhiculent. Elle se distingue aussi du texte poétique caractérisé en particulier par la richesse des images et le jeu sur les signifiants. On comprend dès lors pourquoi la métaphore apparaît de prime abord comme une ennemie du champ de la terminologie qu’il faudrait bannir à tout prix. Cette figure de rhétorique consistant en un transport de sens risque à tout moment de rendre inopérant l’effort d’univocité et de rigueur du travail du terminologue. Mais la métaphore n’est pourtant pas absente des textes de spécialité. Il faut dès lors se demander si cette présence est « accidentelle”, contingente, ou si elle est incontournable et signifiante. Pour cela, il nous faudra étudier à la fois la place de la métaphore dans le texte de spécialité, et le discours des scientifiques portant sur elle. Mais une telle démarche nous laisse prisonnier de la dichotomie entre concept et métaphore et masque peutêtre une parenté inaperçue entre eux. Si le concept est habité par la métaphore, qu’en est-il du discours de spécialité? N’est-il pas réduit à n’être qu’un vaste poème qui ne s’avouerait pas comme tel? Est-elle seulement une figure de style ou aurait-elle un impact qui outrepasseraitsa modeste fonction discursive ? Il semble bien, même si le débat sur la métaphore et son usage est loin d’être clos. Notre théorie s’inscrit plutôt dans le sens d’une réévaluation du sens, d’une extension toujours plus grande de l’impact de ce trope qui, plus qu’une simple finalité esthétique, aurait une

Full Text Available Este artículo se centra en el ocio estético valioso en Aristóteles, partiendo del análisis de la Poética y, específicamente, de la comprensión de la experiencia estética como actividad mental. Se destaca su dimensión ética, realzando su valor en el desarrollo del ser humano, así como el de la propia obra de arte, en la medida en que el poeta ha sabido construirla, encarnando en la trama los hechos y universalizándolos, al modo que le es propio. Aristóteles se refiere a la tragedia, pero por extensión esta valoración proporciona una pauta de lectura de la experiencia de ocio estético. El marco autónomo para el ámbito estético, que inaugura Aristóteles, y su valoración vinculada a la dimensión ética, a la comprensión intelectual y al placer estético proporcionan la base para sostener que el ocio estético se confirma como un horizonte enmarcado en la senda de lo valioso y adecuado para realizar la vida que le es propia al ser humano.

annot8r: GO, EC and KEGG annotation of EST datasets

Schmid Ralf

2008-04-01

Full Text Available Abstract Background The expressed sequence tag (EST methodology is an attractive option for the generation of sequence data for species for which no completely sequenced genome is available. The annotation and comparative analysis of such datasets poses a formidable challenge for research groups that do not have the bioinformatics infrastructure of major genome sequencing centres. Therefore, there is a need for user-friendly tools to facilitate the annotation of non-model species EST datasets with well-defined ontologies that enable meaningful cross-species comparisons. To address this, we have developed annot8r, a platform for the rapid annotation of EST datasets with GO-terms, EC-numbers and KEGG-pathways. Results annot8r automatically downloads all files relevant for the annotation process and generates a reference database that stores UniProt entries, their associated Gene Ontology (GO, Enzyme Commission (EC and Kyoto Encyclopaedia of Genes and Genomes (KEGG annotation and additional relevant data. For each of GO, EC and KEGG, annot8r extracts a specific sequence subset from the UniProt dataset based on the information stored in the reference database. These three subsets are then formatted for BLAST searches. The user provides the protein or nucleotide sequences to be annotated and annot8r runs BLAST searches against these three subsets. The BLAST results are parsed and the corresponding annotations retrieved from the reference database. The annotations are saved both as flat files and also in a relational postgreSQL results database to facilitate more advanced searches within the results. annot8r is integrated with the PartiGene suite of EST analysis tools. Conclusion annot8r is a tool that assigns GO, EC and KEGG annotations for data sets resulting from EST sequencing projects both rapidly and efficiently. The benefits of an underlying relational database, flexibility and the ease of use of the program make it ideally suited for non

La pluralidad, la heterogeneidad y lo multi-procesal conforman el corpus del juicio de gusto actual. Su resultado es la construcción de otros tipos de figuras del mundo, nuevas imágenes de lo real, diversas y distintas, creadas a partir no de la unidad y universalidad del placer estético clásico y dieciochesco, sino por medio de una emoción intersubjetiva y multiforme. El gusto es víctima del tiempo. De lo interesante estético burgués se ha pasado a lo impactante y espectacularizado posindustrial. Entonces, lo light, la alta costura, el turismo, el “mundo del arte”, la word music, la publicidad, los diseños del hogar, la farándula, los artistas jet, la literatura de autoayuda y de intimidades de famosos son las nuevas esferas de un gusto que ha puesto contra la pared todas las antiguas competencias de críticos de arte modernos y del público lector ilustrado en general. ¿Qué tipo de gusto actualmente ejercitamos?, o bien, ¿de qué manera hemos mutado el juicio de gusto en disgusto fragmentado, indescible, descentrado?

Full Text Available DNA repair pathways are necessary to maintain the proper genomic stability and ensure the survival of the organism, protecting it against the damaging effects of endogenous and exogenous agents. In this work, we made an analysis of the expression patterns of DNA repair-related genes in sugarcane, by determining the EST (expressed sequence tags distribution in the different cDNA libraries of the SUCEST transcriptome project. Three different pathways - photoreactivation, base excision repair and nucleotide excision repair - were investigated by employing known DNA repair proteins as probes to identify homologous ESTs in sugarcane, by means of computer similarity search. The results showed that DNA repair genes may have differential expressions in tissues, depending on the pathway studied. These in silico data provide important clues on the potential variation of gene expression, to be confirmed by direct biochemical analysis.As vias de reparo de DNA são requeridas para manter a necessária estabilidade genômica e garantir a sobrevivência do organismo, frente aos efeitos deletérios causados por fatores endógenos e exógenos. Neste trabalho, realizamos a análise dos padrões de expressão dos genes de reparo de DNA encontrados na cana-de-açúcar, pela determinação da distribuição de ESTs nas diferentes bibliotecas de cDNA no projeto de transcriptoma SUCEST. Três vias de reparo - fotorreativação, reparo por excisão de bases e reparo por excisão de nucleotídeos - foram estudadas através do uso de proteínas de reparo como sondas para identificação de ESTs homólogos em cana-de-açúcar, com base na procura computacional de similaridade. Os resultados indicam que os genes de reparo de DNA possuem uma expressão diferencial nos tecidos, dependendo da via de reparo analisada. Esses dados in silico fornecem importantes indícios da expressão diferencial, a qual deve ser confirmada por análises bioquímicas diretas.

Full Text Available BACKGROUND: Microsatellite markers or Simple Sequence Repeats (SSRs are the most popular markers in population/conservation genetics. However, the development of novel microsatellite markers has been impeded by high costs, a lack of available sequence data and technical difficulties. New species-specific microsatellite markers were required to investigate the evolutionary history of the Euphratica tree, Populus euphratica, the only tree species found in the desert regions of Western China and adjacent Central Asian countries. METHODOLOGY/PRINCIPAL FINDINGS: A total of 94,090 non-redundant Expressed Sequence Tags (ESTs from P. euphratica comprising around 63 Mb of sequence data were searched for SSRs. 4,202 SSRs were found in 3,839 ESTs, with 311 ESTs containing multiple SSRs. The most common motif types were trinucleotides (37% and hexanucleotides (33% repeats. We developed primer pairs for all of the identified EST-SSRs (eSSRs and selected 673 of these pairs at random for further validation. 575 pairs (85% gave successful amplification, of which, 464 (80.7% were polymorphic in six to 24 individuals from natural populations across Northern China. We also tested the transferability of the polymorphic eSSRs to nine other Populus species. In addition, to facilitate the use of these new eSSR markers by other researchers, we mapped them onto Populus trichocarpa scaffolds in silico and compiled our data into a web-based database (http://202.205.131.253:8080/poplar/resources/static_page/index.html. CONCLUSIONS: The large set of validated eSSRs identified in this work will have many potential applications in studies on P. euphratica and other poplar species, in fields such as population genetics, comparative genomics, linkage mapping, QTL, and marker-assisted breeding. Their use will be facilitated by their incorporation into a user-friendly web-based database.

Full Text Available Abstract Background Salmonids are of interest because of their relatively recent genome duplication, and their extensive use in wild fisheries and aquaculture. A comprehensive gene list and a comparison of genes in some of the different species provide valuable genomic information for one of the most widely studied groups of fish. Results 298,304 expressed sequence tags (ESTs from Atlantic salmon (69% of the total, 11,664 chinook, 10,813 sockeye, 10,051 brook trout, 10,975 grayling, 8,630 lake whitefish, and 3,624 northern pike ESTs were obtained in this study and have been deposited into the public databases. Contigs were built and putative full-length Atlantic salmon clones have been identified. A database containing ESTs, assemblies, consensus sequences, open reading frames, gene predictions and putative annotation is available. The overall similarity between Atlantic salmon ESTs and those of rainbow trout, chinook, sockeye, brook trout, grayling, lake whitefish, northern pike and rainbow smelt is 93.4, 94.2, 94.6, 94.4, 92.5, 91.7, 89.6, and 86.2% respectively. An analysis of 78 transcript sets show Salmo as a sister group to Oncorhynchus and Salvelinus within Salmoninae, and Thymallinae as a sister group to Salmoninae and Coregoninae within Salmonidae. Extensive gene duplication is consistent with a genome duplication in the common ancestor of salmonids. Using all of the available EST data, a new expanded salmonid cDNA microarray of 32,000 features was created. Cross-species hybridizations to this cDNA microarray indicate that this resource will be useful for studies of all 68 salmonid species. Conclusion An extensive collection and analysis of salmonid RNA putative transcripts indicate that Pacific salmon, Atlantic salmon and charr are 94–96% similar while the more distant whitefish, grayling, pike and smelt are 93, 92, 89 and 86% similar to salmon. The salmonid transcriptome reveals a complex history of gene duplication that is

Full Text Available En el Ecuador, y específicamente en la vida política del país, el teatro ha jugado un papel más importante del que se le ha reconocido. Pensar lo estético relacionado con lo político, puede ser una interesante clave de lectura para el teatro quiteño y, me arriesgo a afirmar, para el teatro a secas. Este análisis no se lo hará desde el teatro político, se pretende, más bien, analizar la dimensión política del mismo y de la relación entre teatro y política. Dicha dimensión política ha tomado diversas caras. Con los matices posibles, ha pasado de las salas a la calle, del costumbrismo a lo grotesco, de las compañías a los grupos. Comprender estos matices con la óptica de lo político puede dar pistas para articular una lógica estética del teatro quiteño

Full Text Available Citrus spp. are economically important crops, which in Brazil are grown mainly in the State of São Paulo. Citrus cultures are attacked by several pathogens, causing severe yield losses. In order to better understand this culture, the Millenium Project (IAC Cordeirópolis was launched in order to sequence Citrus ESTs (expressed sequence tags from different tissues, including leaf, bark, fruit, root and flower. Plants were submitted to biotic and abiotic stresses and investigated under different development stages (adult vs. juvenile. Several cDNA libraries were constructed and the sequences obtained formed the Citrus ESTs database with almost 200,000 sequences. Searches were performed in the Citrus database to investigate the presence of different signaling pathway components. Several of the genes involved in the signaling of sugar, calcium, cytokinin, plant hormones, inositol phosphate, MAPKinase and COP9 were found in the citrus genome and are discussed in this paper. The results obtained may indicate that similar mechanisms described in other plants, such as Arabidopsis, occur in citrus. Further experimental studies must be conducted in order to understand the different signaling pathways present.

In the present study, genetic variation among 40 cucumber genotypes was analyzed by means of morpho-physiological traits and 21 EST-SSR markers. Diversity was observed for morpho-physiological characters like days to 50% female flowering (37-46.9, number of fruits/plant (1.33-5.80), average fruit weight (41-333), vine length (36-364), relative water content (58.5-92.7), electrolyte leakage (15.9-37.1), photosynthetic efficiency (0.40-0.75) and chlorophyll concentration index (11.1-28.6). The pair wise Jaccard similarity coefficient ranged from 0.00 to 0.27 for quantitative traits and 0.24 to 0.96 for EST-SSR markers indicating that the accessions represent genetically diverse populations. With twenty-one EST-SSR markers, polymorphism revealed among 40 cucumber genotypes, number of alleles varied 2-6 with an average 3.05. Polymorphism information content varied from 0.002 to 0.989 (mean = 0.308). The number of effective allele (Ne), expected heterozygosity (He) and unbiased expected heterozygosity (uHe) of these EST-SSRs were 1.079-1.753, 0.074-0.428 and 0.074-0.434, respectively. Same 21 EST-SSR markers transferability checked in four other Cucumis species: snapmelon ( Cucumis melo var. momordica ), muskmelon ( Cucumis melo L.), pickling melon ( Cucumis melo var. conomon ) and wild muskmelon ( Cucumis melo var. agrestis ) with frequency of 61.9, 95.2, 76.2, and 76.2%, respectively. Present study provides useful information on variability, which can assist geneticists with desirable traits for cucumber germplasm utilization. Observed physiological parameters may assists in selection of genotype for abiotic stress tolerance also, EST-SSR markers may be useful for genetic studies in related species.

Con tal fin, se presentará un mapa de la literatura digital en Chile, para luego profundizar en el análisis de dos aspectos que permiten caracterizar una estética de lo digital: la hipertextualidad y el hackeo cultural. A partir de estos elementos y tomando en cuenta que la literatura digital es aquella creada para ser leída en la pantalla de un dispositivo electrónico, se analizan el poema A veces cubierto por las aguas de Carlos Cociña y el poemario Clickable poem@s de Luis Correa-Díaz. Estas obras nos permiten preguntarnos por el estatus de la literatura y la poesía en la era digital, vinculadas a una experiencia estética que pone énfasis en la intervención y el deseo de participación. PALABRAS CLAVE: literatura digital en Chile, poesía digital, estética digital, hipertexto. This article examines an aesthetic experience associated with the digital, which is characterized by the ability of the reader to interact, participate, and manipulate literary works created in this format. First, a map of Chilean digital literature will be presented and then two aspects will be analyzed which allow a description of an aesthetic of the digital: hypertextuality and cultural hacking. As a result of this analysis, and considering that digital literature is that which is created to be read on the screen of an electronic device, two poems will be investigated: A veces cubierto por las aguas by Carlos Cociña and Clickable poem@s by Luis Correa-Díaz. These texts allow us to think about the status of literature and poetry in the digital era, linked with an aesthetic experience which emphasizes intervention and the wish to participate.

2013-07-01

Full Text Available Premise of the study: New microsatellite (simple sequence repeat [SSR] primers were developed from Eucalyptus expressed sequence tags (ESTs and optimized for genetic studies of the southwestern Australian tree E. gomphocephala, which is severely impacted by tree health decline and habitat fragmentation. Methods and Results: A total of 133 gene-homologous EST-SSR primer pairs were designed for Eucalyptus, and 44 were screened in E. gomphocephala. Of these, 17 produced reliable amplification products and 11 were polymorphic. Between two and 13 alleles were observed per locus, and observed heterozygosities ranged from 0.172 to 0.867. All 17 EST-SSRs that amplified E. gomphocephala cross-amplified to at least one of E. marginata, E. camaldulensis, and E. victrix. Conclusions: This set of EST-SSR primer pairs will be valuable tools for future population genetic studies of E. gomphocephala and other eucalypts, particularly for studying gene-linked variation and informing seed-sourcing strategies for ecological restoration.

Identification of candidate genes for human pituitary development by EST analysis

Directory of Open Access Journals (Sweden)

Xiao Huasheng

2009-03-01

Full Text Available Abstract Background The pituitary is a critical neuroendocrine gland that is comprised of five hormone-secreting cell types, which develops in tandem during the embryonic stage. Some essential genes have been identified in the early stage of adenohypophysial development, such as PITX1, FGF8, BMP4 and SF-1. However, it is likely that a large number of signaling molecules and transcription factors essential for determination and terminal differentiation of specific cell types remain unidentified. High-throughput methods such as microarray analysis may facilitate the measurement of gene transcriptional levels, while Expressed sequence tag (EST sequencing, an efficient method for gene discovery and expression level analysis, may no-redundantly help to understand gene expression patterns during development. Results A total of 9,271 ESTs were generated from both fetal and adult pituitaries, and assigned into 961 gene/EST clusters in fetal and 2,747 in adult pituitary by homology analysis. The transcription maps derived from these data indicated that developmentally relevant genes, such as Sox4, ST13 and ZNF185, were dominant in the cDNA library of fetal pituitary, while hormones and hormone-associated genes, such as GH1, GH2, POMC, LHβ, CHGA and CHGB, were dominant in adult pituitary. Furthermore, by using RT-PCR and in situ hybridization, Sox4 was found to be one of the main transcription factors expressed in fetal pituitary for the first time. It was expressed at least at E12.5, but decreased after E17.5. In addition, 40 novel ESTs were identified specifically in this tissue. Conclusion The significant changes in gene expression in both tissues suggest a distinct and dynamic switch between embryonic and adult pituitaries. All these data along with Sox4 should be confirmed to further understand the community of multiple signaling pathways that act as a cooperative network that regulates maturation of the pituitary. It was also suggested that EST

Environmental Factors Modulating the Stability and Enzymatic Activity of the Petrotoga mobilis Esterase (PmEst.

Jose L S Lopes

Full Text Available Enzymes isolated from thermophilic organisms found in oil reservoirs can find applications in many fields, including the oleochemical, pharmaceutical, bioenergy, and food/dairy industries. In this study, in silico identification and recombinant production of an esterase from the extremophile bacteria Petrotoga mobilis (designated PmEst were performed. Then biochemical, bioinformatics and structural characterizations were undertaken using a combination of synchrotron radiation circular dichroism (SRCD and fluorescence spectroscopies to correlate PmEst stability and hydrolytic activity on different substrates. The enzyme presented a high Michaelis-Menten constant (KM 0.16 mM and optimum activity at ~55°C for p-nitrophenyl butyrate. The secondary structure of PmEst was preserved at acid pH, but not under alkaline conditions. PmEst was unfolded at high concentrations of urea or guanidine through apparently different mechanisms. The esterase activity of PmEst was preserved in the presence of ethanol or propanol and its melting temperature increased ~8°C in the presence of these organic solvents. PmEst is a mesophilic esterase with substrate preference towards short-to medium-length acyl chains. The SRCD data of PmEst is in agreement with the prediction of an α/β protein, which leads us to assume that it displays a typical fold of esterases from this family. The increased enzyme stability in organic solvents may enable novel applications for its use in synthetic biology. Taken together, our results demonstrate features of the PmEst enzyme that indicate it may be suitable for applications in industrial processes, particularly, when the use of polar organic solvents is required.

Over the course of the colonial experience, tension infuses the discourse and problems in the use of classicist motifs as imperial models of appropriation become apparent: metaphoric and metonymic references collide; positive and negative connotations overlap; incompatible modes of temporalization contrast with one another; colonial and dissident identifications coincide. The concept of "antiquity" is de-authorized, deconstructed. Readers witness the dissolution of European classicism as a politico-aesthetic 'dispositif' due to the experience of cultural difference.

Full Text Available Considerando a importância da paca (Cuniculus paca, Linnaeus, 1766, tanto como fonte proteica alternativa para a população quanto pela possibilidade de vir a se tornar um animal de experimentação e pela falta de informações sobre a sua anatomia, objetivou-se descrever a morfologia macroscópica e histológica do estômago e do duodeno desse roedor, reconhecendo as relações, forma e posição que esses órgãos estabelecem entre si e com outros órgãos. O estômago da paca é unicavitário, está no plano médio mais voltado para o antímero esquerdo, transversalmente, na região hipocôndrica em posição ventrocaudal, interposto entre o esôfago e o duodeno. O duodeno da paca se inicia em sequência ao estômago, segue caudalmente até o nível da quinta ou sexta vértebra lombar, na altura das quais se curva e toma direção cranial, dirigindo-se até o nível da transição entre a última vértebra torácica e a primeira vértebra lombar, onde se continua como jejuno. Histologicamente, o estômago e o duodeno da paca possuem o padrão característico da arquitetura dos órgãos ocos, apresentando as seguintes túnicas: mucosa, submucosa, muscular e serosa. Da forma que se conduziu este estudo, conclui-se que o estômago e duodeno da paca, de forma geral, possuem características morfológicas macroscópicas e histológicas semelhantes às dos animais domésticos e de outros roedores selvagens.

Diversos grupos sociales (médicos, psicologos, sociólogos, modistos, publicistas, estilistas, esteticistas, periodistas... centran su interés en la definición social del "cuerpo". el objetivo es contribuir a la creación de un modelo ideal único y generalizable, legitimando determinadas prácticas sociales dirigidas hacia este fín. La definición de este modelo esta en manos de un grupo de "diseñadores de cuerpos" que asumen el papel de especificar los límites de la normalidad corporal en nuestra sociedad. La expresión corporal se ha convertido en un lenguaje que, en último extremo, manifiesta el status y la posición social. Por otra parte, en las últimas décadas se plantea la cuestión de conocer como las diferencias biológicas entre los individuos se transforman en factores de discriminación social. En este sentido, diversos problemas de salud actuales chocan con la definición de "cuerpo" ideal. La gordura es un buen ejemplo para comprender como las modas sociales utilizan la categorización de enfermedad "etiquetando" lo "normal" en un momento dado como "patológico" en otro. La exclusión social de las personas obesas, el rechazo a la obesidad y la construcción social de su figura marginal correspondiente, adquieren una relevancia merecedora de un análisis sociológico mas exhaustivo. Por este motivo, es necesario comprender como se han impuesto criterios sociales para estigmatizar a personas cuyo peso no es un riesgo para la salud ni un obstaculo para su vida social...

Full Text Available Abstract Background Currently there exists a limited availability of genetic marker resources in sweetpotato (Ipomoea batatas, which is hindering genetic research in this species. It is necessary to develop more molecular markers for potential use in sweetpotato genetic research. With the newly developed next generation sequencing technology, large amount of transcribed sequences of sweetpotato have been generated and are available for identifying SSR markers by data mining. Results In this study, we investigated 181,615 ESTs for the identification and development of SSR markers. In total, 8,294 SSRs were identified from 7,163 SSR-containing unique ESTs. On an average, one SSR was found per 7.1 kb of EST sequence with tri-nucleotide motifs (42.9% being the most abundant followed by di- (41.2%, tetra- (9.2%, penta- (3.7% and hexa-nucleotide (3.1% repeat types. The top five motifs included AG/CT (26.9%, AAG/CTT (13.5%, AT/TA (10.6%, CCG/CGG (5.8% and AAT/ATT (4.5%. After removing possible duplicate of published EST-SSRs of sweetpotato, a total of non-repeat 7,958 SSR motifs were identified. Based on these SSR-containing sequences, 1,060 pairs of high-quality SSR primers were designed and used for validation of the amplification and assessment of the polymorphism between two parents of one mapping population (E Shu 3 Hao and Guang 2k-30 and eight accessions of cultivated sweetpotatoes. The results showed that 816 primer pairs could yield reproducible and strong amplification products, of which 195 (23.9% and 342 (41.9% primer pairs exhibited polymorphism between E Shu 3 Hao and Guang 2k-30 and among the 8 cultivated sweetpotatoes, respectively. Conclusion This study gives an insight into the frequency, type and distribution of sweetpotato EST-SSRs and demonstrates successful development of EST-SSR markers in cultivated sweetpotato. These EST-SSR markers could enrich the current resource of molecular markers for the sweetpotato community and would

Desartificação da arte e construtos estético-sociais

Directory of Open Access Journals (Sweden)

Rodrigo Duarte

2012-09-01

Full Text Available Este artigo pretende examinar a relação entre a concepção de desartificação (Entkunstung, de Theodor Adorno, e a minha própria noção de “construto estético-social”. A primeira se refere à situação da arte numa época dominada pela indústria cultural e suas mercadorias, na qual, sob certas circunstâncias, os próprios artistas reduzem sua expressão a uma estrutura mínima a fim de prevenir as ameaças à sua arte por parte do “mundo administrado” (Adorno. Já o conceito de “construto estético-social é uma tentativa de compreender alguns fenômenos estéticos contemporâneos que apresentam, por um lado, traços de mercadorias culturais, já que renunciam à complexidade formal das obras de arte propriamente ditas e são – pelo menos parcialmente – veiculados por típicos meios de massa; por outro lado, eles não se enquadram totalmente na categoria de mercadoria cultural, uma vez que apresentam aspectos críticos à sociedade tardo-capitalista e são ligados a ações políticas originadas em comunidades muito pobres, que se entendem a si mesmas como dispostas a transformar aquela sociedade. Fenômenos que se enquadram na descrição de “construtos estético-sociais” podem ser encontrados, por exemplo, na cultura hip hop. A conclusão preliminar a que se chega é que, apesar de a arte desertificada e os “construtos estético-sociais” não serem exatamente a mesma coisa, há uma ligação subterrânea entre essas duas concepções, uma vez que ambas operam – de modo mais ou menos intencional – uma redução na forma de sua expressão a fim de fazer frente às exigências de uma cultura contemporânea autêntica.

Parthiban, S; Govindaraj, P; Senthilkumar, S

2018-03-01

Twenty-five primer pairs developed from genomic simple sequence repeats (SSR) were compared with 25 expressed sequence tags (EST) SSRs to evaluate the efficiency of these two sets of primers using 59 sugarcane genetic stocks. The mean polymorphism information content (PIC) of genomic SSR was higher (0.72) compared to the PIC value recorded by EST-SSR marker (0.62). The relatively low level of polymorphism in EST-SSR markers may be due to the location of these markers in more conserved and expressed sequences compared to genomic sequences which are spread throughout the genome. Dendrogram based on the genomic SSR and EST-SSR marker data showed differences in grouping of genotypes. A total of 59 sugarcane accessions were grouped into 6 and 4 clusters using genomic SSR and EST-SSR, respectively. The highly efficient genomic SSR could subcluster the genotypes of some of the clusters formed by EST-SSR markers. The difference in dendrogram observed was probably due to the variation in number of markers produced by genomic SSR and EST-SSR and different portion of genome amplified by both the markers. The combined dendrogram (genomic SSR and EST-SSR) more clearly showed the genetic relationship among the sugarcane genotypes by forming four clusters. The mean genetic similarity (GS) value obtained using EST-SSR among 59 sugarcane accessions was 0.70, whereas the mean GS obtained using genomic SSR was 0.63. Although relatively lower level of polymorphism was displayed by the EST-SSR markers, genetic diversity shown by the EST-SSR was found to be promising as they were functional marker. High level of PIC and low genetic similarity values of genomic SSR may be more useful in DNA fingerprinting, selection of true hybrids, identification of variety specific markers and genetic diversity analysis. Identification of diverse parents based on cluster analysis can be effectively done with EST-SSR as the genetic similarity estimates are based on functional attributes related to

Strengths and weaknesses of EST-based prediction of tissue-specific alternative splicing

Vingron Martin

2004-09-01

Full Text Available Abstract Background Alternative splicing contributes significantly to the complexity of the human transcriptome and proteome. Computational prediction of alternative splice isoforms are usually based on EST sequences that also allow to approximate the expression pattern of the related transcripts. However, the limited number of tissues represented in the EST data as well as the different cDNA construction protocols may influence the predictive capacity of ESTs to unravel tissue-specifically expressed transcripts. Methods We predict tissue and tumor specific splice isoforms based on the genomic mapping (SpliceNest of the EST consensus sequences and library annotation provided in the GeneNest database. We further ascertain the potentially rare tissue specific transcripts as the ones represented only by ESTs derived from normalized libraries. A subset of the predicted tissue and tumor specific isoforms are then validated via RT-PCR experiments over a spectrum of 40 tissue types. Results Our strategy revealed 427 genes with at least one tissue specific transcript as well as 1120 genes showing tumor specific isoforms. While our experimental evaluation of computationally predicted tissue-specific isoforms revealed a high success rate in confirming the expression of these isoforms in the respective tissue, the strategy frequently failed to detect the expected restricted expression pattern. The analysis of putative lowly expressed transcripts using normalized cDNA libraries suggests that our ability to detect tissue-specific isoforms strongly depends on the expression level of the respective transcript as well as on the sensitivity of the experimental methods. Especially splice isoforms predicted to be disease-specific tend to represent transcripts that are expressed in a set of healthy tissues rather than novel isoforms. Conclusions We propose to combine the computational prediction of alternative splice isoforms with experimental validation for

Full Text Available The fluoride has volcanic activity and abundantly exists in environment combining with other elements as fluoride compounds. Recent researches indicated that the molecular mechanisms of intracellular fluoride toxicity were very complex. However, the molecular mechanisms underlying the effects on gene expression of chronic fluoride-induced damage is unknown, especially the detailed regulatory process of mitochondria. In the present study, we screened the differential expression ESTs associated with fluorosis by DDRT-PCR in rat liver. We gained 8 genes, 3 new ESTs, and 1 unknown function sequence and firstly demonstrated that microsomal glutathione S-transferase 1 (MGST1, ATP synthase H+ transporting mitochondrial F0 complex subunit C1, selenoprotein S, mitochondrial IF1 protein, and mitochondrial succinyl-CoA synthetase alpha subunit were participated in mitochondria metabolism, functional and structural damage process caused by chronic fluorosis. This information will be very helpful for understanding the molecular mechanisms of fluorosis.

Full Text Available Resumo Trata-se de relato de experiência em estágio supervisionado em Psicologia Organizacional e do Trabalho (POT envolvendo um grupo de alunos de uma Instituição de Educação Superior (IES localizada no Estado do Espírito Santo. O objetivo central foi discutir os aspectos teóricos e práticos que influenciaram na formação profissional do discente em Psicologia, tendo como foco o estágio supervisionado. Além de relatar a experiência, foi realizado um levantamento junto aos ex-alunos sobre as contribuições do estágio na sua formação educacional e profissional. Da experiência relatada foi possível verificar que: a instituição das Diretrizes Curriculares Nacionais (DCN constituiu-se em um marco na flexibilização curricular dos cursos; o estágio é um componente curricular de integração entre ensino, pesquisa e prática; e o estágio em POT requer dos discentes conhecimentos multidisciplinares. Além desses aspectos, observou-se que a prática do estágio supervisionado indica o rompimento com a imagem negativa do psicólogo que atua em POT, limitada à aplicação de testes e psicotécnicas. De fato, a atividade do psicólogo em POT mostrou-se muito mais ampla e complexa, sobretudo em termos dos impactos de sua intervenção no ambiente organizacional.

Full Text Available Abstract Background Establishing genomic resources for closely related species will provide comparative insights that are crucial for understanding diversity and variability at multiple levels of biological organization. We developed ESTs for Mexican axolotl (Ambystoma mexicanum and Eastern tiger salamander (A. tigrinum tigrinum, species with deep and diverse research histories. Results Approximately 40,000 quality cDNA sequences were isolated for these species from various tissues, including regenerating limb and tail. These sequences and an existing set of 16,030 cDNA sequences for A. mexicanum were processed to yield 35,413 and 20,599 high quality ESTs for A. mexicanum and A. t. tigrinum, respectively. Because the A. t. tigrinum ESTs were obtained primarily from a normalized library, an approximately equal number of contigs were obtained for each species, with 21,091 unique contigs identified overall. The 10,592 contigs that showed significant similarity to sequences from the human RefSeq database reflected a diverse array of molecular functions and biological processes, with many corresponding to genes expressed during spinal cord injury in rat and fin regeneration in zebrafish. To demonstrate the utility of these EST resources, we searched databases to identify probes for regeneration research, characterized intra- and interspecific nucleotide polymorphism, saturated a human – Ambystoma synteny group with marker loci, and extended PCR primer sets designed for A. mexicanum / A. t. tigrinum orthologues to a related tiger salamander species. Conclusions Our study highlights the value of developing resources in traditional model systems where the likelihood of information transfer to multiple, closely related taxa is high, thus simultaneously enabling both laboratory and natural history research.

2016-03-01

Full Text Available A novel esterase, MtEst45, was isolated from a fosmid genomic library of Microbulbifer thermotolerans DAU221. The encoding gene is predicted to have a mass of 45,564 Da and encodes 495 amino acids, excluding a 21 amino acid signal peptide. MtEst45 showed a low amino acid identity (approximately 23–24% compared with other lipolytic enzymes belonging to Family III, a closely related bacterial lipolytic enzyme family. MtEst45 also showed a conserved GXSXG motif, G131IS133YG135, which was reported as active site of known lipolytic enzymes, and the putative catalytic triad composed of D237 and H265. Because these mutants of MtEst45, which was S133A, D237N, and H265L, had no activity, these catalytic triad essential for the enzyme catalysis. MtEst45 was overexpressed in Escherichia coli BL21 (DE3 and purified via His-tag affinity chromatography. The optimal pH and temperature of MtEst45 were estimated to be 8.17 and 46.27°C by response surface methodology, respectively. Additionally, MtEst45 was also active between 1–15°C. The optimal hydrolysis substrate for MtEst45 among p-nitrophenyl esters (C2–C18 was p-nitrophenyl butyrate, and the Km and Vmax values were 0.0998 mM and 550 μmol/min/mg of protein, respectively. MtEst45 was strongly inhibited by Hg2+, Zn2+, and Cu2+ ions; by phenylmethanesulfonyl fluoride; and by β-mercaptoethanol. Ca2+ did not affect the enzyme’s activity. These biochemical properties, sequence identity, and phylogenetic analysis suggest that MtEst45 represents a novel and valuable bacterial lipolytic enzyme family and is useful for biotechnological applications.

2005-10-01

Full Text Available Abstract Background Ginkgo biloba L. is the only surviving member of one of the oldest living seed plant groups with medicinal, spiritual and horticultural importance worldwide. As an evolutionary relic, it displays many characters found in the early, extinct seed plants and extant cycads. To establish a molecular base to understand the evolution of seeds and pollen, we created a cDNA library and EST dataset from the reproductive structures of male (microsporangiate, female (megasporangiate, and vegetative organs (leaves of Ginkgo biloba. Results RNA from newly emerged male and female reproductive organs and immature leaves was used to create three distinct cDNA libraries from which 6,434 ESTs were generated. These 6,434 ESTs from Ginkgo biloba were clustered into 3,830 unigenes. A comparison of our Ginkgo unigene set against the fully annotated genomes of rice and Arabidopsis, and all available ESTs in Genbank revealed that 256 Ginkgo unigenes match only genes among the gymnosperms and non-seed plants – many with multiple matches to genes in non-angiosperm plants. Conversely, another group of unigenes in Gingko had highly significant homology to transcription factors in angiosperms involved in development, including MADS box genes as well as post-transcriptional regulators. Several of the conserved developmental genes found in Ginkgo had top BLAST homology to cycad genes. We also note here the presence of ESTs in G. biloba similar to genes that to date have only been found in gymnosperms and an additional 22 Ginkgo genes common only to genes from cycads. Conclusion Our analysis of an EST dataset from G. biloba revealed genes potentially unique to gymnosperms. Many of these genes showed homology to fully sequenced clones from our cycad EST dataset found in common only with gymnosperms. Other Ginkgo ESTs are similar to developmental regulators in higher plants. This work sets the stage for future studies on Ginkgo to better understand seed and

Mata-Montero, Manrique; Shalaby, Nabil; Sheppard, Bradley

2013-01-01

Obtaining unique oligos from an EST database is a problem of great importance in bioinformatics, particularly in the discovery of new genes and the mapping of the human genome. Many algorithms have been developed to find unique oligos, many of which are much less time consuming than the traditional brute force approach. An algorithm was presented by Zheng et al. (2004) which finds the solution of the unique oligos search problem efficiently. We implement this algorithm as well as several new algorithms based on some theorems included in this paper. We demonstrate how, with these new algorithms, we can obtain unique oligos much faster than with previous ones. We parallelize these new algorithms to further improve the time of finding unique oligos. All algorithms are run on ESTs obtained from a Barley EST database.

Est25, a ketoprofen-specific hormone-sensitive lipase from a metagenomic library, was crystallized and diffraction data were collected to 1.49 Å resolution. Ketoprofen, a nonsteroidal anti-inflammatory drug, inhibits the synthesis of prostaglandin. A novel hydrolase (Est25) with high ketoprofen specificity has previously been identified using a metagenomic library from environmental samples.

Full Text Available ¿Cómo escribir sobre imágenes en la cuales el comienzo (creación y el final (obra están relacionados con experiencias personales de una catástrofe? ¿Cómo se traduce el cuerpo de la obra en la biografía de una sociedad? ¿Cómo hacer que a partir de la escritura sobre imágenes que retratan una conmoción se nos devele la enorme cantidad de derivas para los estudios culturales a propósito de nociones tan escurridizas como biografía, cuerpo social, memoria, desastre? Tales preguntas están relacionadas con dos formas de obras, una autoral y otra como medio de construcción de una identidad. Y, entre otras, éstas son las preguntas y el objetivo del presente texto en el cual identidad, memoria, experiencia y representación son signos relevantes en la cimentación del cuerpo de obra. Al mismo tiempo, las obras que se crean en situaciones extremas durante o después de catástrofes, desgracias, dictaduras, son construidas desde los márgenes y/o periferias, incluso de las minorías, y este concepto está relacionado con la noción de género. La obra, en este caso la fotografía, es el cuerpo biográfico, político y social. El concepto de autobiografía surge como elemento central en este artículo. Cada imagen, cada palabra son las memorias y confesiones de autores, donde se incluye la autora de este artículo en un doble rol de observador que experimenta la conmoción que provocó esta creación y, también, como sujeto que recibe la experiencia convertida en obra (las fotografías que originaron esta Muestra de aquellos que experimentaron pérdidas y miedos. Estas emociones son la construcción de un lugar, de un momento, creando un mapa visual de lo que ya no está. Y esa ausencia es esencial para comprender las imágenes y para dar cuenta en el texto de ese silencio tras la catástrofe. ¿Se puede escribir o fotografiar ese silencio?

Upgrading Unconventional Oil Resources with the EST Process

Energy Technology Data Exchange (ETDEWEB)

Delbianco, Alberto; Meli, Salvatori; Panariti, Nicolleta; Rispoli, Giacomo

2007-07-01

We strongly believe that unconventional oils will play a much larger role in the growth of supply than is currently recognized. As a matter of fact, whereas the earth's conventional proven world oil reserves are 1.3 trillion barrels, extra-heavy plus bitumen resources amount to about 4 trillion barrels. The unconventional oils are characterized by low API gravity (<10), high viscosity and high concentration of poisons such as sulphur, nitrogen, metals, and asphaltenes. For this reason, a key role for the full exploitation of these hydrocarbon resources is played by the downstream processes that are required to upgrade and convert them into valuable products. In this scenario, Eni has developed a novel hydrocracking process (EST: Eni Slurry Technology) which is particularly well-suited for the conversion and upgrading of heavy feedstocks (conventional vacuum residues, extra-heavy oils and bitumen). EST employs nano-sized hydrogenation catalysts and an original process scheme that allow complete feedstock conversion to an upgraded synthetic crude oil (SCO) with an API gravity gain greater than 20 and avoid the production of residual by-products, such as pet-coke or heavy fuel oil. A Commercial Demonstration Unit (CDP) of 1200 bbl/d capacity is successfully operating in the Eni's Taranto refinery since November 2005. (auth)

2011-06-01

Full Text Available RESUMO Nas últimas décadas, a toxina botulínica tem sido aplicada para fins terapêuticos em inúmeras afecções. A toxina do tipo A foi aprovada primeiramente em 1989 para o uso em estrabismo, blefaroespasmo e espasmo hemifacial de pacientes maiores que 12 anos de idade. A observação de que pacientes tratados de blefaroespasmo com toxina botulínica apresentavam um efeito adicional de diminuição das rugas de expressão inspirou estudos sobre a aplicação cosmética da toxina. Recentemente, a toxina botulínica do tipo A foi aprovada para fins estéticos. Este trabalho relata um caso de ocorrência de estrabismo após aplicação de toxina botulínica na face para fins estéticos.

Restos de vida en Bajo este sol tremendo de Carlos Busqued

Full Text Available Este trabajo se propone analizar cómo la novela de Carlos Busqued Bajo este sol tremendo (2009 se apoya en la representación de vidas desechadas, basura y todo tipo de restos para instalarse en una tensión entre orden y exceso. La narración plantea una lógica en la que la basura, en lugar de constituirse en un indicio que posibilite la reconstrucción del paisaje social, exhibe lo desbordante, lo inasimilable y los vacíos de sentido. En el mundo que nos presenta Busqued lo viviente se vuelve resto en la medida en que encarna una heterogeneidad irreductible a cualquier estructura social y productiva. This paper analyzes the way in which Carlos Busqued's novel Bajo este sol tremendo (2009 is based on the representation of discarded lives, garbage, and all kinds of remains and thus proposes a tension between order and excess. The narration raises a logic in which garbage, instead of constituting an indicator that allows for the reconstruction of the social landscape, exhibits the overflowing, the unassimilable, and the voids of meaning. In the world that Busqued presents, the living becomes a remainder because it embodies an irreducible heterogeneity with regards to any social and productive structure.

Full length open reading frame of pyrethroid detoxification gene, Est3385, contains 963 nucleotides. This gene was identified and cloned based on the genome sequence of Rhodopseudomonas palustris PSB-S available at the GneBank. The predicted amino acid sequence of Est3385 shared moderate identities (30-46%) with the known homologous esterases. Phylogenetic analysis revealed that Est3385 was a member in the esterase family I. Recombinant Est3385 was heterologous expressed in E. coli, purified and characterized for its substrate specificity, kinetics and stability under various conditions. The optimal temperature and pH for Est3385 were 35 °C and 6.0, respectively. This enzyme could detoxify various pyrethroid pesticides and degrade the optimal substrate fenpropathrin with a Km and Vmax value of 0.734 ± 0.013 mmol·l -1 and 0.918 ± 0.025 U·µg -1 , respectively. No cofactor was found to affect Est3385 activity but substantial reduction of enzymatic activity was observed when metal ions were applied. Taken together, a new pyrethroid degradation esterase was identified and characterized. Modification of Est3385 with protein engineering toolsets should enhance its potential for field application to reduce the pesticide residue from agroecosystems.

Pattern analysis approach reveals restriction enzyme cutting abnormalities and other cDNA library construction artifacts using raw EST data

2012-05-01

Full Text Available Abstract Background Expressed Sequence Tag (EST sequences are widely used in applications such as genome annotation, gene discovery and gene expression studies. However, some of GenBank dbEST sequences have proven to be “unclean”. Identification of cDNA termini/ends and their structures in raw ESTs not only facilitates data quality control and accurate delineation of transcription ends, but also furthers our understanding of the potential sources of data abnormalities/errors present in the wet-lab procedures for cDNA library construction. Results After analyzing a total of 309,976 raw Pinus taeda ESTs, we uncovered many distinct variations of cDNA termini, some of which prove to be good indicators of wet-lab artifacts, and characterized each raw EST by its cDNA terminus structure patterns. In contrast to the expected patterns, many ESTs displayed complex and/or abnormal patterns that represent potential wet-lab errors such as: a failure of one or both of the restriction enzymes to cut the plasmid vector; a failure of the restriction enzymes to cut the vector at the correct positions; the insertion of two cDNA inserts into a single vector; the insertion of multiple and/or concatenated adapters/linkers; the presence of 3′-end terminal structures in designated 5′-end sequences or vice versa; and so on. With a close examination of these artifacts, many problematic ESTs that have been deposited into public databases by conventional bioinformatics pipelines or tools could be cleaned or filtered by our methodology. We developed a software tool for Abnormality Filtering and Sequence Trimming for ESTs (AFST, http://code.google.com/p/afst/ using a pattern analysis approach. To compare AFST with other pipelines that submitted ESTs into dbEST, we reprocessed 230,783 Pinus taeda and 38,709 Arachis hypogaea GenBank ESTs. We found 7.4% of Pinus taeda and 29.2% of Arachis hypogaea GenBank ESTs are “unclean” or abnormal, all of which could be cleaned

Le big bang n'est pas une théorie comme les autres. Ce n'est d'ailleurs pas une théorie physique au sens propre du terme, mais un scénario cosmologique issu des équations de la relativité générale. Il est le modèle qui s'ajuste le mieux aux observations actuelles, mais à quel prix ? Il nous livre un Univers composé à 96 % de matière et d'énergie noires inconnues. C'est donc un euphémisme que de dire que le big bang semble poser autant - sinon plus - de questions qu'il n'en résout. En ce sens, le big bang apparaît davantage comme une paramétrisation de notre ignorance plutôt que comme une modélisation d'un phénomène. Pourtant, le succès du big bang et l'adhésion qu'il suscite, tant dans la sphère scientifique que dans la sphère médiatique, ne se démentent pas. Surmédiatisé, son statut dépasse celui de modèle théorique, et la simple évocation de son nom suffit pour justifier des opérations de marketing scientifique ou rejeter des cosmologies alternatives.

Full Text Available Este artigo estuda as concepções de estética e experiência de Clifford Geertz e Walter Benjamin como possibilidades argumentativas e metodológicas para pensar a realidade e suas formas estéticas. Utiliza-se para isso as discussões metodológicas de Geertz, especialmente a respeito do lugar da estética e de sua relação com os demais âmbitos do humano, que encetaram uma nova forma de concebê-los para a etnografia e antropologia de modo geral, e os estudos de Benjamin a respeito da estética como expressão fisionômica de uma época, de determinada realidade, especialmente os que se referem sobre a modernidade. Constata-se essa possibilidade a partir da observação de que a estética e a experiência, nos autores, são tomadas como dimensões da realidade que se relacionam, não de modo mecânico, e sim como âmbitos que atravessam a realidade, os artefatos estéticos, os discursos, e esses assim devem ser observados.This article study the conceptions of aesthetics and experience of Clifford Geertz and Walter Benjamin as argumentative and methodological possibilities for thinking reality and its aesthetic forms. Uses for this Geertz's methodological discussions, especially regarding the place of aesthetics and its relation to other spheres of the human, which has embarked on a new way of conceiving them to ethnography and anthropology in general, and studies Benjamin about the aesthetics and physiognomical expression of an era, a certain reality, especially those concerning about modernity. There is that possibility from the observation that the aesthetics and experience, in the authors, are taken as the dimensions of reality are related, not mechanically, but as areas that cross the reality, the aesthetic artifacts, the speeches, and so these must be observed.

2015-01-01

Full Text Available Simple sequence repeats (SSRs are among the most important markers for population analysis and have been widely used in plant genetic mapping and molecular breeding. Expressed sequence tag-SSR (EST-SSR markers, located in the coding regions, are potentially more efficient for QTL mapping, gene targeting, and marker-assisted breeding. In this study, we investigated 51,694 nonredundant unigenes, assembled from clean reads from deep transcriptome sequencing with a Solexa/Illumina platform, for identification and development of EST-SSRs in Chinese cabbage. In total, 10,420 EST-SSRs with over 12 bp were identified and characterized, among which 2744 EST-SSRs are new and 2317 are known ones showing polymorphism with previously reported SSRs. A total of 7877 PCR primer pairs for 1561 EST-SSR loci were designed, and primer pairs for twenty-four EST-SSRs were selected for primer evaluation. In nineteen EST-SSR loci (79.2%, amplicons were successfully generated with high quality. Seventeen (89.5% showed polymorphism in twenty-four cultivars of Chinese cabbage. The polymorphic alleles of each polymorphic locus were sequenced, and the results showed that most polymorphisms were due to variations of SSR repeat motifs. The EST-SSRs identified and characterized in this study have important implications for developing new tools for genetics and molecular breeding in Chinese cabbage.

2014-01-01

Full Text Available In this study, a collection of 24,840 expressed sequence tags (ESTs generated from five mango (Mangifera indica L. cDNA libraries was mined for EST-based simple sequence repeat (SSR markers. Over 1,000 ESTs with SSR motifs were detected from more than 24,000 EST sequences with di- and tri-nucleotide repeat motifs the most abundant. Of these, 25 EST-SSRs in genes involved in plant development, stress response, and fruit color and flavor development pathways were selected, developed into PCR markers and characterized in a population of 32 mango selections including M. indica varieties, and related Mangifera species. Twenty-four of the 25 EST-SSR markers exhibited polymorphisms, identifying a total of 86 alleles with an average of 5.38 alleles per locus, and distinguished between all Mangifera selections. Private alleles were identified for Mangifera species. These newly developed EST-SSR markers enhance the current 11 SSR mango genetic identity panel utilized by the Australian Mango Breeding Program. The current panel has been used to identify progeny and parents for selection and the application of this extended panel will further improve and help to design mango hybridization strategies for increased breeding efficiency.

The cupuassu tree (Theobroma grandiflorum) (Willd. ex Spreng.) Schum. is a fruitful species from the Amazon with great economical potential, due to the multiple uses of its fruit´s pulp and seeds in the food and cosmetic industries, including the production of cupulate, an alternative to chocolate. In order to support the cupuassu breeding program and to select plants presenting both pulp/seed quality and fungal disease resistance, SSRs from Next Generation Sequencing ESTs were obtained and used in diversity analysis. From 8,330 ESTs, 1,517 contained one or more SSRs (1,899 SSRs identified). The most abundant motifs identified in the EST-SSRs were hepta- and trinucleotides, and they were found with a minimum and maximum of 2 and 19 repeats, respectively. From the 1,517 ESTs containing SSRs, 70 ESTs were selected based on their functional annotation, focusing on pulp and seed quality, as well as resistance to pathogens. The 70 ESTs selected contained 77 SSRs, and among which, 11 were polymorphic in cupuassu genotypes. These EST-SSRs were able to discriminate the cupuassu genotype in relation to resistance/susceptibility to witches' broom disease, as well as to pulp quality (SST/ATT values). Finally, we showed that these markers were transferable to cacao genotypes, and that genome availability might be used as a predictive tool for polymorphism detection and primer design useful for both Theobroma species. To our knowledge, this is the first report involving EST-SSRs from cupuassu and is also a pioneer in the analysis of marker transferability from cupuassu to cacao. Moreover, these markers might contribute to develop or saturate the cupuassu and cacao genetic maps, respectively.

2013-01-01

Full Text Available Premise of the study: Simple sequence repeat markers were developed based on expressed sequence tags (EST-SSR and screened for polymorphism among 23 Pisum sativum individuals to assist development and refinement of pea linkage maps. In particular, the SSR markers were developed to assist in mapping of white mold disease resistance quantitative trait loci. Methods and Results: Primer pairs were designed for 46 SSRs identified in EST contiguous sequences assembled from a 454 pyrosequenced transcriptome of the pea cultivar, ‘LIFTER’. Thirty-seven SSR markers amplified PCR products, of which 11 (30% SSR markers produced polymorphism in 23 individuals, including parents of recombinant inbred lines, with two to four alleles. The observed and expected heterozygosities ranged from 0 to 0.43 and from 0.31 to 0.83, respectively. Conclusions: These EST-SSR markers for pea will be useful for refinement of pea linkage maps, and will likely be useful for comparative mapping of pea and as tools for marker-based pea breeding.

Full Text Available Academia and practitioners confirm that software project effort prediction is crucial for an accurate software project management. However, software development effort estimation is uncertain by nature. Literature has developed methods to improve estimation correctness, using artificial intelligence techniques in many cases. Following this path, this paper presents SEffEst, a framework based on fuzzy logic and neural networks designed to increase effort estimation accuracy on software development projects. Trained using ISBSG data, SEffEst presents remarkable results in terms of prediction accuracy.

Genetic diversity of Phytophthora sojae isolates in Heilongjiang Province in China assessed by RAPD and EST-SSR

Science.gov (United States)

Wu, J. J.; Xu, P. F.; Liu, L. J.; Wang, J. S.; Lin, W. G.; Zhang, S. Z.; Wei, L.

Random-amplified polymorphic DNA (RAPD) and EST-SSR markers were used to estimate the genetic relationship among thirty-nine P.sojae isolates from three locations in Heilongjiang Province, and nine isolates from Ohio in America were made as reference strains. 10 of 50 RAPD primers and 5 of 33 EST-SSR were polymorphic across 48 P.sojae isolates. Similarity values among P.sojae isolates were from 49% to 82% based on the RAPD data. The similarities based on EST-SSR markers ranged from 47% to 85%. The genetic diversity revealed by EST-SSR marker analysis was higher than that obtained from RAPD. The similarity matrices for the SSR data and the RAPD data were moderately correlated (r = 0.47). Genetic similarity coefficients were also relatively lower, which demonstrated complicated genetic background within each location. The high similarity values range revealed the ability of RAPD/EST-SSR markers to distinguish even among morphological similar phytophthora.

2015-01-01

With the aim to increase the number of functional markers in resource poor crop like cultivated peanut (Arachis hypogaea), large numbers of available expressed sequence tags (ESTs) in the public databases, were employed for the development of novel EST derived simple sequence repeat (SSR) markers. From 16424 unigenes, 2784 (16.95%) SSRs containing unigenes having 3373 SSR motifs were identified. Of these, 2027 (72.81%) sequences were annotated and 4124 gene ontology terms were assigned. Among different SSR motif-classes, tri-nucleotide repeats (33.86%) were the most abundant followed by di-nucleotide repeats (27.51%) while AG/CT (20.7%) and AAG/CTT (13.25%) were the most abundant repeat-motifs. A total of 2456 EST-SSR novel primer pairs were designed, of which 366 unigenes having relevance to various stresses and other functions, were PCR validated using a set of 11 diverse peanut genotypes. Of these, 340 (92.62%) primer pairs yielded clear and scorable PCR products and 39 (10.66%) primer pairs exhibited polymorphisms. Overall, the number of alleles per marker ranged from 1-12 with an average of 3.77 and the PIC ranged from 0.028 to 0.375 with an average of 0.325. The identified EST-SSRs not only enriched the existing molecular markers kitty, but would also facilitate the targeted research in marker-trait association for various stresses, inter-specific studies and genetic diversity analysis in peanut.

Full Text Available Little information is available on gene expression profiling of halophyte A. canescens. To elucidate the molecular mechanism for stress tolerance in A. canescens, a full-length complementary DNA library was generated from A. canescens exposed to 400 mM NaCl, and provided 343 high-quality ESTs. In an evaluation of 343 valid EST sequences in the cDNA library, 197 unigenes were assembled, among which 190 unigenes (83.1% ESTs were identified according to their significant similarities with proteins of known functions. All the 343 EST sequences have been deposited in the dbEST GenBank under accession numbers JZ535802 to JZ536144. According to Arabidopsis MIPS functional category and GO classifications, we identified 193 unigenes of the 311 annotations EST, representing 72 non-redundant unigenes sharing similarities with genes related to the defense response. The sets of ESTs obtained provide a rich genetic resource and 17 up-regulated genes related to salt stress resistance were identified by qRT-PCR. Six of these genes may contribute crucially to earlier and later stage salt stress resistance. Additionally, among the 343 unigenes sequences, 22 simple sequence repeats (SSRs were also identified contributing to the study of A. canescens resources.

Full Text Available The objectives of this work were to investigate the genetic variation in 79 soybean (Glycine max accessions from different regions of the world, to cluster the accessions based on their similarity, and to test the correlation between the two types of markers used. Simple sequence repeat markers present in genomic (SSR and in expressed regions (EST-SSR were used. Thirty SSR primer-pairs were selected (20 genomic and 10 EST-SSR based on their distribution on the 20 genetic linkage groups of soybean, on their trinucleotide repetition unit and on their polymorphism information content. All analyzed loci were polymorphic, and 259 alleles were found. The number of alleles per locus varied from 2-21, with an average of 8.63. The accessions exhibit a significant number of rare alleles, with genotypes 19, 35, 63 and 65 carrying the greater number of exclusive alleles. Accessions 75 and 79 were the most similar and accessions 31 and 35, and 40 and 78, were the most divergent ones. A low correlation between SSR and EST-SSR data was observed, thus genomic and expressed microsatellite markers are required for an appropriate analysis of genetic diversity in soybean. The genetic diversity observed was high and allowed the formation of five groups and several subgroups. A moderate relationship between genetic divergence and geographic origin of accessions was observed.Os objetivos deste trabalho foram avaliar a diversidade genética de 79 acessos de soja de diferentes regiões do mundo, agrupá-los de acordo com a similaridade e testar a correlação entre os dois tipos de marcadores utilizados.

Full Text Available Kivircik sheep is an important local Turkish sheep according to its meat quality and milk productivity. The aim of this study was to analyze gene expression profiles of both prenatal and postnatal stages for the Kivircik sheep. Therefore, two different cDNA libraries, which were taken from the same Kivircik sheep mammary gland tissue at prenatal and postnatal stages, were constructed. Total 3072 colonies which were randomly selected from the two libraries were sequenced for developing a sheep ESTs collection. We used Phred/Phrap computer programs for analysis of the raw EST and readable EST sequences were assembled with the CAP3 software. Putative functions of all unique sequences and statistical analysis were determined by Geneious software. Total 422 ESTs have over 80% similarity to known sequences of other organisms in NCBI classified by Panther database for the Gene Ontology (GO category. By comparing gene expression profiles, we observed some putative genes that may be relative to reproductive performance or play important roles in milk synthesis and secretion. A total of 2414 ESTs have been deposited to the NCBI GenBank database (GW996847–GW999260. EST data in this study have provided a new source of information to functional genome studies of sheep.

Fernando vallejo: y la clausura ciudadanía estética de la literatura mundial

2011-09-01

Full Text Available Este artículo encara deliberaciones actuales sobre la literatura global, desde la perspectiva de la novela urbana colombiana del siglo XX. Explorando la tensión entre las historias de las narrativas globales y locales, el autor examina hasta qué punto se puede defender que la literatura global y sus apéndices socioculturales se prestan a proyectos emancipatorios, y hasta qué punto esos apéndices simplifican en exceso los espacios de producción literaria densa. Ubicando la Weltliteratur de Goethe en el contexto de una Colombia estéticamente globalizada, e invocando la relación particularmente espinosa entre Fernando Vallejo y Gabriel García Márquez como caso de estudio, este artículo avanza que las casas editoriales internacionales y las culturas de la crítica crean una ciudadanía estética limitante que sigue siendo dominada por las decisiones de mercadeo de las grandes casas editoriales y el gusto de los públicos lectores, muy alejados del contexto de los bestsellers “periféricos”.

Zingiber officinale is a model spice herb, well known for its medicinal value. It is primarily a vegetatively propagated commercial crop. However, considerable diversity in its morphology, fiber content and chemoprofiles has been reported. The present study explores the utility of EST-derived markers in studying genetic diversity in different accessions of Z. officinale and their cross transferability within the Zingiberaceae family. A total of 38,115 ESTs sequences were assembled to generate 7850 contigs and 10,762 singletons. SSRs were searched in the unigenes and 515 SSR-containing ESTs were identified with a frequency of 1 SSR per 25.21 kb of the genome. These ESTs were also annotated using BLAST2GO. Primers were designed for 349 EST-SSRs and 25 primer pairs were randomly picked for EST SSR study. Out of these, 16 primer pairs could be optimized for amplification in different accessions of Z. officinale as well as other species belonging to Zingiberaceae. GES454, GES466, GES480 and GES486 markers were found to exhibit 100% cross-transferability among different members of Zingiberaceae.

2010-10-01

Cynodon species are multiple-use grasses that display varying levels of adaptation to biotic and abiotic stress. Previously identified EST-SSR primers were characterized and multiplexed to assess the level of genetic diversity present within a collection of almost 1200 Cynodon accessions from across Australia. • Two multiplex reactions were developed comprising a total of 16 EST-SSR markers. All SSR markers amplified across different Cynodon species and different levels of ploidy. The number of alleles ranged from one to eight per locus and the total number of alleles for the germplasm collection was 79. • The 16 markers show sufficient variation for the characterization of Cynodon core collections and analysis of population genetic diversity in Cynodon grasses.

Pero además de la evidencia que puede reunirse acerca de este vinculo indisoluble entre ciencia y filosofía a nivel teórico y metodológico, está presente un ideal estético común que atraviesa las realizaciones del intelecto griego, reorganizando y recomponiendo los elementos provenientes de la observación y la reflexión. Dicho ideal estético cohesiona al pensamiento y le da armonía a la ejecución práctica. De los ocho rasgos destacados del arte griego que señala Gardner en su artículo titulado "Las lámparas del arte griego", tres son, a mi modo de ver, esenciales para percibir la profunda relación que se instaura en la Grecia antigua entre filosofía, ciencia y estética. Estos rasgos esenciales son: Naturalismo, Humanismo y Equilibrio

Ana Rita Brancalioni

Full Text Available RESUMO Objetivos: propor e analisar listas com palavras-estímulo em contextos linguísticos favorecedores para segmentos-alvo na posição de onset simples, utilizando um padrão de programação para pontuar o nível de favorecimento dessas palavras. Métodos: foi desenvolvido um padrão de programação, em linguagem Java, para determinar a pontuação das palavras-estímulo, que considerou o somatório dos pesos atribuídos às variáveis linguísticas: posição na palavra, tonicidade, número de sílabas, contexto precedente e contexto seguinte, para cada segmento-alvo. Foram utilizadas 748 palavras para elaboração de listas de palavras-estímulo para cada segmento-alvo. Todas as palavras-estímulo tiveram sua pontuação de favorecimento calculada a partir do padrão de programação e classificadas quanto ao nível de favorecimento. Resultados: verificou-se que as palavras-estímulo classificadas como favorecedoras (PEF foram as que alcançaram maior pontuação, uma vez que contemplaram os contextos mais favorecedores para produção do segmento-alvo. Contudo não foi necessário que todos os contextos favorecedores fossem privilegiados para as palavras serem classificadas como PEF. Conclusão: o padrão de programação desenvolvido foi eficiente para pontuar o nível de favorecimento das palavras-estímulo. Além disso, deve haver uma preferência por palavras-estímulo favorecedoras, ou que alcançam maior pontuação, porém nem sempre essas palavras são as mais adequadas para o tratamento de qualquer sistema fonológico desviante.

Ligusticum chuanxiong is a well-known traditional Chinese medicine plant. The study on its molecular markers development and germplasm resources is very important. In this study, we obtained 24 422 unigenes by assembling transcriptome sequencing reads of L. chuanxiong root. EST-SSR was detected and 4 073 SSR loci were identified. EST-SSR distribution and characteristic analysis results showed that the mono-nucleotide repeats were the main repeat types, accounting for 41.0%. In addition, the sequences containing SSR were functionally annotated in Gene Ontology (GO) and KEGG pathway and were assigned to 49 GO categories, 242 KEGG pathways, among them 2 201 sequences were annotated against Nr database. By validating 235 EST-SSRs,74 primer pairs were ultimately proved to have high quality amplification. Subsequently, genetic diversity analysis, UPGMA cluster analysis, PCoA analysis and population structure analysis of 34 L. chuanxiong germplasm resources were carried out with 74 primer pairs. In both UPGMA tree and PCoA results, L. chuanxiong resources were clustered into two groups, which are believed to be partial related to their geographical distribution. In this study, EST-SSRs in L. chuanxiong was firstly identified, and newly developed molecular markers would contribute significantly to further genetic diversity study, the purity detection, gene mapping, and molecular breeding.

2005-03-01

ESTminer is a Web application and database schema for interactive mining of expressed sequence tag (EST) contig and cluster datasets. The Web interface contains a query frame that allows the selection of contigs/clusters with specific cDNA library makeup or a threshold number of members. The results are displayed as color-coded tree nodes, where the color indicates the fractional size of each cDNA library component. The nodes are expandable, revealing library statistics as well as EST or contig members, with links to sequence data, GenBank records or user configurable links. Also, the interface allows 'queries within queries' where the result set of a query is further filtered by the subsequent query. ESTminer is implemented in Java/JSP and the package, including MySQL and Oracle schema creation scripts, is available from http://cggc.agtec.uga.edu/Data/download.asp agingle@uga.edu.

Full Text Available Development of Expressed Sequence Tag-Simple Sequence Repeat (EST-SSR markers derived from public database is known to be more efficient, faster and low cost. The objective of this study was to generate a new set of EST-SSR markers for broccoli and its related species and their usefulness for assessing their genetic diversity. A total of 202 Brassica oleracea ESTs were retrieved from NCBI and then assembled into 172 unigenes by means of CAP3 program. Identification of SSRs was carried out using web-based tool, RepeatMasker software. Afterwards, EST-SSR markers were developed using Primer3 program. Among the identified SSRs, trinucleotide repeats were the most common repeat types, which accounted for about 50%. A total of eight primer pairs were successfully designed and yielded amplification products. Among them, five markers were polymorphic and displayed a total of 30 alleles with an average number of six alleles per locus. The polymorphic markers were subsequently used for analyzing genetic diversity of 36 B. oleracea cultivars including 22 broccoli, five cauliflower and nine kohlrabi cultivars based on genetic similarity matrix as implemented in NTSYS program. At similarity coefficient of 61%, a UPGMA clustering dendrogram effectively separated 36 genotypes into three main groups, where 30 out of 36 genotypes were clearly discriminated. The result obtained in the present study would help breeders in selecting parental lines for crossing. Moreover, the novel EST-SSR markers developed in the study could be a valuable tool for differentiating cultivars of broccoli and related species.

We identified and characterized EST-SSRs with strong discrimination power against Lavandula angustifolia and Lavandula x intermedia . The markers also showed considerable cross-species transferability rate into six related Lavandula species. Lavenders (Lavandula) are important economical crops grown around the globe for essential oil production. In an attempt to develop genetic markers for these plants, we analyzed over 13,000 unigenes developed from L. angustifolia and L. x intermedia EST databases, and identified 3,459 simple sequence repeats (SSR), which were dominated by trinucleotides (41.2 %) and dinucleotides (31.45 %). Approximately, 19 % of the unigenes contained at least one SSR marker, over 60 % of which were localized in the UTRs. Only 252 EST-SSRs were 18 bp or longer from which 31 loci were validated, and 24 amplified discrete fragments with 85 % polymorphism in L. x intermedia and L. angustifolia. The average number of alleles in L. x intermedia and L. angustifolia were 3.42 and 3.71 per marker with average PIC values of 0.47 and 0.52, respectively. These values suggest a moderate to strong level of informativeness for the markers, with some loci producing unique fingerprints. The cross-species transferability rate of the markers ranges 50-100 % across eight species. The utility of these markers was assessed in eight Lavandula species and 15 L. angustifolia and L. x intermedia cultivars, and the dendrogram deduced from their similarity indexes successfully delineated the species into their respective sections and the cultivars into their respective species. These markers have potential for application in fingerprinting, diversity studies and marker-assisted breeding of Lavandula.

The brown planthopper (BPH), Nilaparvata lugens (Hemiptera, Delphacidae), is a serious insect pests of rice plants. Major means of BPH control are application of agricultural chemicals and cultivation of BPH resistant rice varieties. Nevertheless, BPH strains that are resistant to agricultural chemicals have developed, and BPH strains have appeared that are virulent against the resistant rice varieties. Expressed sequence tag (EST) analysis and related applications are useful to elucidate the mechanisms of resistance and virulence and to reveal physiological aspects of this non-model insect, with its poorly understood genetic background. More than 37,000 high-quality ESTs, excluding sequences of mitochondrial genome, microbial genomes, and rDNA, have been produced from 18 libraries of various BPH tissues and stages. About 10,200 clusters have been made from whole EST sequences, with average EST size of 627 bp. Among the top ten most abundantly expressed genes, three are unique and show no homology in BLAST searches. The actin gene was highly expressed in BPH, especially in the thorax. Tissue-specifically expressed genes were extracted based on the expression frequency among the libraries. An EST database is available at our web site. The EST library will provide useful information for transcriptional analyses, proteomic analyses, and gene functional analyses of BPH. Moreover, specific genes for hemimetabolous insects will be identified. The microarray fabricated based on the EST information will be useful for finding genes related to agricultural and biological problems related to this pest.

Full Text Available La identidad de una obra expresada a través de la escritura se teje en las voces y esfuerzos que se encarnan en memoria y dejan huella en el relato. El maestro es acción de este lenguaje movido por el historial social y cultural que permite hacer de la escritura un oficio ético y estético donde la mano construye y nombra las emociones que atraviesan al cuerpo. La escritura es el testimonio vital del maestro como artesano; es el arte del lenguaje que sale de su silencio con la lectura del relato, pero es, además, la potencia del pensamiento puesto en pretexto estético donde se pregunta y se reflexiona por el tiempo y por el espacio de la palabra, es decir, las cronologías, kairologías, territorialidades y escenarios de las esferas educativas. Sobre estos presupuestos se propone una discusión pedagógica en torno a la necesidad de pensar la escritura artesanal como intención estética y política donde se plasma el testimonio del compromiso ético del maestro, pero también la perspectiva de los nuevos retos que la educación debe asumir para reencontrar el lenguaje con la vida y con las herencias socioculturales que dan cuenta del sujeto y de las subjetividades que confluyen en los procesos de formación, y que tienen despliegue y búsqueda en el escenario creativo y productivo de la escritura. Se intentará, entonces, reivindicar una pedagogía de la posibilidad en el lenguaje, una narratividad donde la memoria traza un puente para el encuentro de épocas, de rostros, de acontecimientos, de silencios y de saberes, donde el maestro está llamado a tejer, tallar, dibujar, componer y comunicar las artesanías que la educación ha olvidado, es decir, recuperar la memoria estética, lo cual también implica un olvido de las formas hegemónicas del arte.

Foxtail millet is a gramineous crop with low water requirement. Despite its high water use efficiency, less attention has been paid to the molecular genetics of foxtail millet. This article reports the construction of subtracted cDNA libraries from foxtail millet seedlings under dehydration stress and the expression profile analysis of 1947 UniESTs from the subtracted cDNA libraries by a cDNA microarray. The results showed that 95 and 57 ESTs were upregulated by dehydration stress, respectively, in roots and shoots of seedlings and that 10 and 27 ESTs were downregulated, respectively, in roots and shoots. The expression profile analysis showed that genes induced in foxtail millet roots were different from those in shoots during dehydration stress and that the early response to dehydration stress in foxtail millet roots was the activation of the glycolysis metabolism. Moreover, protein degradation pathway may also play a pivotal role in drought-tolerant responses of foxtail millet. Finally, Northern blot analysis validated well the cDNA microarray data.

Est-Y29, a novel oligomeric class C β-lactamase from a metagenomic library, was crystallized in space group I4 1 and diffraction data were collected to 1.49 Å resolution. β-Lactam antibiotics such as penicillins and cephalosporins have a four-atom ring as a common element in their structure. The β-lactamases, which catalyze the inactivation of these antibiotics, are of great interest because of their high incidence in pathogenic bacteria. A novel oligomeric class C β-lactamase (Est-Y29) from a metagenomic library was expressed, purified and crystallized. The recombinant protein was expressed in Escherichia coli with an N-terminal 6×His tag and purified to homogeneity. EstY-29 was crystallized and X-ray intensity data were collected to 1.49 Å resolution using synchrotron radiation

Full Text Available A compreensão da diversidade genética fornece elementos básicos sobre a dinâmica e funcionamento de populações, auxiliando na conservação e uso sustentável das espécies. Supõe-se que populações sucessionais precoces poderiam ser geneticamente mais diferenciadas do que populações sucessionais mais tardias. Visando testar esta hipótese, o presente trabalho teve como objetivo analisar a variabilidade genética de populações de Eugenia uniflora L. em manchas florestais em diferentes estádios sucessionais. Foram selecionadas duas áreas em diferentes estádios de sucessão, sendo a primeira em estádio inicial e a segunda em estádio avançado. A área de estudo apresenta um remanescente florestal em transição de Floresta Ombrófila Mista e Floresta Estacional Semidecídua. Por meio da técnica de RAPD (Random Amplified Polymorphic DNA e análise multivariada, a diversidade gênica esperada e a porcentagem de loci polimórficos foram estimadas, além da similaridade genética entre as populações de cada mancha florestal e a diversidade de cada área por meio do índice de diversidade de Simpson. Os resultados indicaram 79% de loci polimórficos para a área em estádio avançado e 70% para a área em estádio inicial de sucessão. A similaridade genética entre pares de indivíduos variou entre 0,55 e 0,86 na área em estádio inicial de sucessão e entre 0,45 e 0,78 para a área em estádio avançado. Não houve diferenças significativas entre a diversidade das duas áreas (P = 89. Um escalonamento multidimensional não-métrico indicou menor distância genética entre os indivíduos da área em estádio inicial. Da mesma forma, uma análise de similaridade - ANOSIM indicou separação entre os indivíduos das duas áreas.

2007-06-01

Full Text Available Abstract Background The eastern oyster, Crassostrea virginica (Gmelin 1791, is an economically important species cultured in many areas in North America. It is also ecologically important because of the impact of its filter feeding behaviour on water quality. Populations of C. virginica have been threatened by overfishing, habitat degradation, and diseases. Through genome research, strategies are being developed to reverse its population decline. However, large-scale expressed sequence tag (EST resources have been lacking for this species. Efficient generation of EST resources from this species has been hindered by a high redundancy of transcripts. The objectives of this study were to construct a normalized cDNA library for efficient EST analysis, to generate thousands of ESTs, and to analyze the ESTs for microsatellites and potential single nucleotide polymorphisms (SNPs. Results A normalized and subtracted C. virginica cDNA library was constructed from pooled RNA isolated from hemocytes, mantle, gill, gonad and digestive tract, muscle, and a whole juvenile oyster. A total of 6,528 clones were sequenced from this library generating 5,542 high-quality EST sequences. Cluster analysis indicated the presence of 635 contigs and 4,053 singletons, generating a total of 4,688 unique sequences. About 46% (2,174 of the unique ESTs had significant hits (E-value ≤ 1e-05 to the non-redundant protein database; 1,104 of which were annotated using Gene Ontology (GO terms. A total of 35 microsatellites were identified from the ESTs, with 18 having sufficient flanking sequences for primer design. A total of 6,533 putative SNPs were also identified using all existing and the newly generated EST resources of the eastern oysters. Conclusion A high quality normalized cDNA library was constructed. A total of 5,542 ESTs were generated representing 4,688 unique sequences. Putative microsatellite and SNP markers were identified. These genome resources provide the

Euphorbiaceae represents flowering plants family of tropical and sub-tropical region rich in secondary metabolites of economic importance. To understand and assess the genetic makeup among the members, this study was undertaken to characterize and compare SSR markers from publicly available ESTs and GSSs of nine selected species of the family. Mining of SSRs was performed by MISA, primer designing by Primer3, while functional annotation, gene ontology (GO) and enrichment analysis were performed by Blast2GO. A total 12,878 number of SSRs were detected from 101,701 number of EST sequences. SSR density ranged from 1 SSR/3.22 kb to 1 SSR/15.65 kb. A total of 1873 primer pairs were designed for the annotated SSR-Contigs. About 77.07% SSR-ESTs could be assigned a significant match to the protein database. 3037 unique SSR-FDM were assigned and IPR003657 (WRKY Domain) was found to be the most dominant FDM among the members. 1810 unique GO terms obtained were further subjected to enrichment analysis to obtain 513 statistically significant GO terms mapped to the SSR containing ESTs. Most frequent enriched GO terms were, GO:0003824 for molecular function, GO:0006350 for biological process and GO:0005886 for cellular component, justifying the richness of defensive secondary metabolites and phytomedicine within the family. The results from this study provides tangible insight to genetic make-up and distribution of SSRs. Functional annotation corresponded many genes of unknown functions which may be considered as novel genes or genes responsible for stress specific secondary metabolites. Further studies are required to understand stress specific genes accountable for leveraging the synthesis of secondary metabolites.

Full Text Available Abstract Background Norway spruce is widely distributed across Europe and the predominant tree of the Alpine region. Fast growth and the fact that timber can be harvested cost-effectively in relatively young populations define its status as one of the economically most important tree species of Northern Europe. In this study, EST derived simple sequence repeat (SSR markers were developed for the assessment of putative functional diversity in Austrian Norway spruce stands. Results SSR sequences were identified by analyzing 14,022 publicly available EST sequences. Tri-nucleotide repeat motifs were most abundant in the data set followed by penta- and hexa-nucleotide repeats. Specific primer pairs were designed for sixty loci. Among these, 27 displayed polymorphism in a testing population of 16 P. abies individuals sampled across Austria and in an additional screening population of 96 P. abies individuals from two geographically distinct Austrian populations. Allele numbers per locus ranged from two to 17 with observed heterozygosity ranging from 0.075 to 0.99. Conclusions We have characterized variable EST SSR markers for Norway spruce detected in expressed genes. Due to their moderate to high degree of variability in the two tested screening populations, these newly developed SSR markers are well suited for the analysis of stress related functional variation present in Norway spruce populations.

2017-06-01

To increase the likelihood of successful implementation of interventions and promote dissemination across real-world settings, it is essential to evaluate outcomes related to dimensions other than Effectiveness alone. Glasgow and colleagues' RE-AIM framework specifies four additional types of outcomes that are important to decision-makers: Reach, Adoption, Implementation (including cost), and Maintenance. To further strengthen RE-AIM, we propose integrating qualitative assessments in an expanded framework: RE-AIM Qualitative Evaluation for Systematic Translation (RE-AIM QuEST), a mixed methods framework. RE-AIM QuEST guides formative evaluation to identify real-time implementation barriers and explain how implementation context may influence translation to additional settings. RE-AIM QuEST was used to evaluate a pharmacist-led hypertension management intervention at 3 VA facilities in 2008-2009. We systematically reviewed each of the five RE-AIM dimensions and created open-ended companion questions to quantitative measures and identified qualitative and quantitative data sources, measures, and analyses. To illustrate use of the RE-AIM QuEST framework, we provide examples of real-time, coordinated use of quantitative process measures and qualitative methods to identify site-specific issues, and retrospective use of these data sources and analyses to understand variation across sites and explain outcomes. For example, in the Reach dimension, we conducted real-time measurement of enrollment across sites and used qualitative data to better understand and address barriers at a low-enrollment site. The RE-AIM QuEST framework may be a useful tool for improving interventions in real-time, for understanding retrospectively why an intervention did or did not work, and for enhancing its sustainability and translation to other settings.

Cherubini Marcello

2010-10-01

Full Text Available Abstract Background Expressed Sequence Tags (ESTs are a source of simple sequence repeats (SSRs that can be used to develop molecular markers for genetic studies. The availability of ESTs for Quercus robur and Quercus petraea provided a unique opportunity to develop microsatellite markers to accelerate research aimed at studying adaptation of these long-lived species to their environment. As a first step toward the construction of a SSR-based linkage map of oak for quantitative trait locus (QTL mapping, we describe the mining and survey of EST-SSRs as well as a fast and cost-effective approach (bin mapping to assign these markers to an approximate map position. We also compared the level of polymorphism between genomic and EST-derived SSRs and address the transferability of EST-SSRs in Castanea sativa (chestnut. Results A catalogue of 103,000 Sanger ESTs was assembled into 28,024 unigenes from which 18.6% presented one or more SSR motifs. More than 42% of these SSRs corresponded to trinucleotides. Primer pairs were designed for 748 putative unigenes. Overall 37.7% (283 were found to amplify a single polymorphic locus in a reference full-sib pedigree of Quercus robur. The usefulness of these loci for establishing a genetic map was assessed using a bin mapping approach. Bin maps were constructed for the male and female parental tree for which framework linkage maps based on AFLP markers were available. The bin set consisting of 14 highly informative offspring selected based on the number and position of crossover sites. The female and male maps comprised 44 and 37 bins, with an average bin length of 16.5 cM and 20.99 cM, respectively. A total of 256 EST-SSRs were assigned to bins and their map position was further validated by linkage mapping. EST-SSRs were found to be less polymorphic than genomic SSRs, but their transferability rate to chestnut, a phylogenetically related species to oak, was higher. Conclusion We have generated a bin map for oak

Surviving extreme polar winters by desiccation: clues from Arctic springtail (Onychiurus arcticus EST libraries

Directory of Open Access Journals (Sweden)

Kube Michael

2007-12-01

Full Text Available Abstract Background Ice, snow and temperatures of -14°C are conditions which most animals would find difficult, if not impossible, to survive in. However this exactly describes the Arctic winter, and the Arctic springtail Onychiurus arcticus regularly survives these extreme conditions and re-emerges in the spring. It is able to do this by reducing the amount of water in its body to almost zero: a process that is called "protective dehydration". The aim of this project was to generate clones and sequence data in the form of ESTs to provide a platform for the future molecular characterisation of the processes involved in protective dehydration. Results Five normalised libraries were produced from both desiccating and rehydrating populations of O. arcticus from stages that had previously been defined as potentially informative for molecular analyses. A total of 16,379 EST clones were generated and analysed using Blast and GO annotation. 40% of the clones produced significant matches against the Swissprot and trembl databases and these were further analysed using GO annotation. Extraction and analysis of GO annotations proved an extremely effective method for identifying generic processes associated with biochemical pathways, proving more efficient than solely analysing Blast data output. A number of genes were identified, which have previously been shown to be involved in water transport and desiccation such as members of the aquaporin family. Identification of these clones in specific libraries associated with desiccation validates the computational analysis by library rather than producing a global overview of all libraries combined. Conclusion This paper describes for the first time EST data from the arctic springtail (O. arcticus. This significantly enhances the number of Collembolan ESTs in the public databases, providing useful comparative data within this phylum. The use of GO annotation for analysis has facilitated the identification of a

MÉTODOS: Las tasas de mortalidad por diferentes causas de muerte en España de 1971 a 1992 son ajustadas empleando cuatro poblaciones de referencia: poblaciones españolas de 1971 y 1992, población estándar europea y población estándar mundial. Los resultados obtenidos con las cuatro poblaciones se comparan empleando tres indicadores: diferencia entre las tasas de 1992 y 1971, razón entre las tasas de 1992 y 1971y cambio anual porcentual entre 1971 y 1992. RESULTADOS: En la mayor parte de las causas de muerte estudiadas incluyendo el total de causas, la cardiopatía isquémica y casi todos los tumores, la razón de tasas y el porcentaje de cambio anual son similares con independencia de cuál sea la población estándar empleada. En cambio, la diferencia de tasas es muy diferente en función de la población de referencia. En las enfermedades infecciosas y el cáncer de testículo se produce la situación contraria: la diferencia de tasas es robusta mientras que la razón de tasas varía con la población estándar. Finalmente, la mortalidad por neumonía, enfermedad de Parkinson y cáncer de encéfalo muestra cambios en los tres indicadores utilizados. CONCLUSIONES: Es necesario realizar un análisis de las tasas específicas por edad antes de proceder a su ajuste. Este análisis permite averiguar si el ajuste por edades es correcto y qué indicador (diferencia, razón o cambio porcentual será adecuado para realizar comparaciones.

Coral reef ecosystems are renowned for their diversity and beauty. Their immense ecological success is due to a symbiotic association between cnidarian hosts and unicellular dinoflagellate algae, known as zooxanthellae. These algae are photosynthetic and the cnidarian-zooxanthellae association is based on nutritional exchanges. Maintenance of such an intimate cellular partnership involves many crosstalks between the partners. To better characterize symbiotic relationships between a cnidarian host and its dinoflagellate symbionts, we conducted a large-scale EST study on a symbiotic sea anemone, Anemonia viridis, in which the two tissue layers (epiderm and gastroderm) can be easily separated. A single cDNA library was constructed from symbiotic tissue of sea anemones A. viridis in various environmental conditions (both normal and stressed). We generated 39,939 high quality ESTs, which were assembled into 14,504 unique sequences (UniSeqs). Sequences were analysed and sorted according to their putative origin (animal, algal or bacterial). We identified many new repeated elements in the 3'UTR of most animal genes, suggesting that these elements potentially have a biological role, especially with respect to gene expression regulation. We identified genes of animal origin that have no homolog in the non-symbiotic starlet sea anemone Nematostella vectensis genome, but in other symbiotic cnidarians, and may therefore be involved in the symbiosis relationship in A. viridis. Comparison of protein domain occurrence in A. viridis with that in N. vectensis demonstrated an increase in abundance of some molecular functions, such as protein binding or antioxidant activity, suggesting that these functions are essential for the symbiotic state and may be specific adaptations. This large dataset of sequences provides a valuable resource for future studies on symbiotic interactions in Cnidaria.

Analysis of cassava (Manihot esculenta) ESTs: A tool for the discovery of genes

International Nuclear Information System (INIS)

Zapata, Andres; Neme, Rafik; Sanabria, Carolina; Lopez, Camilo

2011-01-01

Cassava (Manihot esculenta) is the main source of calories for more than 1,000 millions of people around the world and has been consolidated as the fourth most important crop after rice, corn and wheat. Cassava is considered tolerant to abiotic and biotic stress conditions; nevertheless these characteristics are mainly present in non-commercial varieties. Genetic breeding strategies represent an alternative to introduce the desirable characteristics into commercial varieties. A fundamental step for accelerating the genetic breeding process in cassava requires the identification of genes associated to these characteristics. One rapid strategy for the identification of genes is the possibility to have a large collection of ESTs (expressed sequence tag). In this study, a complete analysis of cassava ESTs was done. The cassava ESTs represent 80,459 sequences which were assembled in a set of 29,231 unique genes (unigen), comprising 10,945 contigs and 18,286 singletones. These 29,231 unique genes represent about 80% of the genes of the cassava's genome. Between 5% and 10% of the unigenes of cassava not show similarity to any sequences present in the NCBI database and could be consider as cassava specific genes. a functional category was assigned to a group of sequences of the unigen set (29%) following the Gene Ontology Vocabulary. the molecular function component was the best represented with 43% of the sequences, followed by the biological process component (38%) and finally the cellular component with 19%. in the cassava ESTs collection, 3,709 microsatellites were identified and they could be used as molecular markers. this study represents an important contribution to the knowledge of the functional genomic structure of cassava and constitutes an important tool for the identification of genes associated to agricultural characteristics of interest that could be employed in cassava breeding programs.

2015-01-01

Epimedium species has gained prime importance due to their medicinal and economic values. Therefore, in this study, 26 genomic SSR and 10 EST-SSR markers were developed for 13 medicinal species of the Epimedium genus and one out-group species Vancouveria hexandra W. J. Hooker to explore the existing genetic diversity. A total of 100 alleles by genomic SSR and 65 by EST-SSR were detected. The genomic SSR markers were presented between 2-7 alleles per locus. The observed heterozygosity (Ho) and expected heterozygosity (He) ranged from 0.00 to 4.5 and 0.0254 to 2.8108, respectively. Similarly, for EST-SSR, these values were ranged from 3.00 to 4.00 and 1.9650 to 2.7142. The number of alleles for EST-SSR markers ranged from 3 to 10 with an average of 3.51 per loci. It has been concluded that medicinally important species of the genus Epimedium possesses lower intraspecific genetic variation.

Gene discovery using massively parallel pyrosequencing to develop ESTs for the flesh fly Sarcophaga crassipalpis

2009-05-01

Full Text Available Abstract Background Flesh flies in the genus Sarcophaga are important models for investigating endocrinology, diapause, cold hardiness, reproduction, and immunity. Despite the prominence of Sarcophaga flesh flies as models for insect physiology and biochemistry, and in forensic studies, little genomic or transcriptomic data are available for members of this genus. We used massively parallel pyrosequencing on the Roche 454-FLX platform to produce a substantial EST dataset for the flesh fly Sarcophaga crassipalpis. To maximize sequence diversity, we pooled RNA extracted from whole bodies of all life stages and normalized the cDNA pool after reverse transcription. Results We obtained 207,110 ESTs with an average read length of 241 bp. These reads assembled into 20,995 contigs and 31,056 singletons. Using BLAST searches of the NR and NT databases we were able to identify 11,757 unique gene elements (ES. crassipalpis unigenes among GO Biological Process functional groups with that of the Drosophila melanogaster transcriptome suggests that our ESTs are broadly representative of the flesh fly transcriptome. Insertion and deletion errors in 454 sequencing present a serious hurdle to comparative transcriptome analysis. Aided by a new approach to correcting for these errors, we performed a comparative analysis of genetic divergence across GO categories among S. crassipalpis, D. melanogaster, and Anopheles gambiae. The results suggest that non-synonymous substitutions occur at similar rates across categories, although genes related to response to stimuli may evolve slightly faster. In addition, we identified over 500 potential microsatellite loci and more than 12,000 SNPs among our ESTs. Conclusion Our data provides the first large-scale EST-project for flesh flies, a much-needed resource for exploring this model species. In addition, we identified a large number of potential microsatellite and SNP markers that could be used in population and systematic

Cross-species transferability and expressed sequence tags (ESTs) in public databases are cost-effective means for developing simple sequence repeats (SSRs) for less-studied species like medicinal plants. In this study, 11 EST-SSR markers developed from 742 available ESTs of Withania Somnifera EST sequences and 95 SSR primer pairs derived from other solanaceous crops (tomato, eggplant, chili, and tobacco) were utilized for their amplification and validation. Out of 11, 10 EST-SSRs showed good amplification quality and produced 13 loci with a product size ranging between 167 and 291 bp. Similarly, of the 95 cross-genera SSR loci assayed, 20 (21 %) markers showed the transferability of 5, 27, 32, and 14.2 % from eggplant, chili, tomato, and tobacco, respectively, to ashwagandha. In toto, these 30 SSR markers reported here will be valuable resources and may be applicable for the analysis of intra- and inter-specific genetic diversity in ashwagandha for which till date no information about SSR is available.

Speculative petroleum systems of the Punta del Este Basin (offshore Uruguay

Ethel Morales

Full Text Available ABSTRACT: The Uruguayan continental margin was generated as the result of the breakup of Gondwana and, later, the opening of the South Atlantic Ocean, which began in the Jurassic. Three major areas of Meso-Cenozoic sedimentation are located in the Uruguayan offshore: the Punta del Este Basin, the southernmost sector of the Pelotas Basin and the Oriental del Plata Basin. These basins share the classical stages of tectono-sedimentary evolution of the other Atlantic basins, including the prerift (Paleozoic, rift (Jurassic-Early Cretaceous, transition (Barremian-Aptian and postrift (Aptian-present phases. Based on the analysis of basin evolution through seismic sections and well data as well as on the establishment of analogies with productive Atlantic basins, four speculative petroleum systems are proposed for the Punta del Este Basin: 1 Marine petroleum system of the prerift stage: Devonian/Permian-Devonian/Permian(?, 2 Lacustrine petroleum system of the synrift stage: Neocomian-Neocomian(?, 3 Marine petroleum system of the Cretaceous postrift: Aptian-Late Cretaceous(?, 4 Marine petroleum system of the Cenozoic postrift: Paleocene-Paleogene/Neogene(?.

Development of ESTs from chickpea roots and their use in diversity analysis of the Cicer genus

Directory of Open Access Journals (Sweden)

2005-08-01

Full Text Available Abstract Background Chickpea is a major crop in many drier regions of the world where it is an important protein-rich food and an increasingly valuable traded commodity. The wild annual Cicer species are known to possess unique sources of resistance to pests and diseases, and tolerance to environmental stresses. However, there has been limited utilization of these wild species by chickpea breeding programs due to interspecific crossing barriers and deleterious linkage drag. Molecular genetic diversity analysis may help predict which accessions are most likely to produce fertile progeny when crossed with chickpea cultivars. While, trait-markers may provide an effective tool for breaking linkage drag. Although SSR markers are the assay of choice for marker-assisted selection of specific traits in conventional breeding populations, they may not provide reliable estimates of interspecific diversity, and may lose selective power in backcross programs based on interspecific introgressions. Thus, we have pursued the development of gene-based markers to resolve these problems and to provide candidate gene markers for QTL mapping of important agronomic traits. Results An EST library was constructed after subtractive suppressive hybridization (SSH of root tissue from two very closely related chickpea genotypes (Cicer arietinum. A total of 106 EST-based markers were designed from 477 sequences with functional annotations and these were tested on C. arietinum. Forty-four EST markers were polymorphic when screened across nine Cicer species (including the cultigen.

Sin embargo, el uso de este tipo de estímulos plantea una serie de problemas de carácter ético y metodológico. Consecuentemente, en trabajos recientes se comprobó que podía obtenerse condicionamiento sustituyendo el habitual ruido blanco por un sonido cuya aversividad se derivaba más de su contenido semántico que de su intens...

Appraising the Early-est earthquake monitoring system for tsunami alerting at the Italian Candidate Tsunami Service Provider

2015-09-01

In this paper we present and discuss the performance of the procedure for earthquake location and characterization implemented in the Italian Candidate Tsunami Service Provider at the Istituto Nazionale di Geofisica e Vulcanologia (INGV) in Rome. Following the ICG/NEAMTWS guidelines, the first tsunami warning messages are based only on seismic information, i.e., epicenter location, hypocenter depth, and magnitude, which are automatically computed by the software Early-est. Early-est is a package for rapid location and seismic/tsunamigenic characterization of earthquakes. The Early-est software package operates using offline-event or continuous-real-time seismic waveform data to perform trace processing and picking, and, at a regular report interval, phase association, event detection, hypocenter location, and event characterization. Early-est also provides mb, Mwp, and Mwpd magnitude estimations. mb magnitudes are preferred for events with Mwp ≲ 5.8, while Mwpd estimations are valid for events with Mwp ≳ 7.2. In this paper we present the earthquake parameters computed by Early-est between the beginning of March 2012 and the end of December 2014 on a global scale for events with magnitude M ≥ 5.5, and we also present the detection timeline. We compare the earthquake parameters automatically computed by Early-est with the same parameters listed in reference catalogs. Such reference catalogs are manually revised/verified by scientists. The goal of this work is to test the accuracy and reliability of the fully automatic locations provided by Early-est. In our analysis, the epicenter location, hypocenter depth and magnitude parameters do not differ significantly from the values in the reference catalogs. Both mb and Mwp magnitudes show differences to the reference catalogs. We thus derived correction functions in order to minimize the differences and correct biases between our values and the ones from the reference catalogs. Correction of the Mwp

The mining of toxin-like polypeptides from EST database by single residue distribution analysis.

Science.gov (United States)

Kozlov, Sergey; Grishin, Eugene

2011-01-31

Novel high throughput sequencing technologies require permanent development of bioinformatics data processing methods. Among them, rapid and reliable identification of encoded proteins plays a pivotal role. To search for particular protein families, the amino acid sequence motifs suitable for selective screening of nucleotide sequence databases may be used. In this work, we suggest a novel method for simplified representation of protein amino acid sequences named Single Residue Distribution Analysis, which is applicable both for homology search and database screening. Using the procedure developed, a search for amino acid sequence motifs in sea anemone polypeptides was performed, and 14 different motifs with broad and low specificity were discriminated. The adequacy of motifs for mining toxin-like sequences was confirmed by their ability to identify 100% toxin-like anemone polypeptides in the reference polypeptide database. The employment of novel motifs for the search of polypeptide toxins in Anemonia viridis EST dataset allowed us to identify 89 putative toxin precursors. The translated and modified ESTs were scanned using a special algorithm. In addition to direct comparison with the motifs developed, the putative signal peptides were predicted and homology with known structures was examined. The suggested method may be used to retrieve structures of interest from the EST databases using simple amino acid sequence motifs as templates. The efficiency of the procedure for directed search of polypeptides is higher than that of most currently used methods. Analysis of 39939 ESTs of sea anemone Anemonia viridis resulted in identification of five protein precursors of earlier described toxins, discovery of 43 novel polypeptide toxins, and prediction of 39 putative polypeptide toxin sequences. In addition, two precursors of novel peptides presumably displaying neuronal function were disclosed.

La modernidad, en esa época, adquiere toda su madurez y habilita un giro, en la filosofía, occidental, que estetiza la razón. Radicalizado el giro, en el llamado postestructuralismo, es Vilém Flusser, quien, desde su nomadismo e indisciplinamiento, plantea una radical crítica al pensamiento hegeliano, desde “la imagen técnica” como “elogio de la superficialidad”, o, en nuestro parecer, “teoría de la pantalla”.

El argumento de la pobreza del estímulo, una vez más

Full Text Available El argumento más conocido en favor del innatismo de ciertas estructuras mentales sigue siendo el ‘Argumento de la Pobreza del estímulo’ (APE. La idea general del APE es que el conocimiento que se requiere para desarrollar una cierta capacidad cognitiva excede en gran medida la información disponible en el entorno, de manera que el organismo contribuye con información innata. Un examen de la literatura del APE lingüístico muestra que aún no está del todo claro qué clase de argumento es y lo que realmente muestra. Mi objetivo en este trabajo es ofrecer un diagnóstico de la estrategia innatista que utiliza el APE. Así, distingo tres tipos de APE y argumento, en primer lugar, que la versión más apropiada, según ciertos criterios empíricos y teóricos, no parece ser suficiente para el innatismo lingüístico y, en segundo lugar, que para ser suficiente, suele complementarse con un argumento ‘de sillón’, cuya consecuencia es que convierte al innatismo en una hipótesis empírica debilitada.

Extra heavy oil and refinery residues upgrading through Eni Slurry Technology : first EST commercial unit

Rispoli, G.; Sanfilippo, D.; Amoroso, A [Eni S.p.A., Rome (Italy)

2009-07-01

The production of heavy crude oils is projected to continue to grow in the upstream oil industry given that large reserves of unconventional extra heavy crude and bitumen exist in several geographic areas including Canada and Venezuela. As reserves of conventional crude oil continue to decline, these unconventional feedstocks are becoming an opportunity to pursue, but they require effective technologies for upgrading and meeting the growing demand for light and middle distillate fuels. This paper described the proprietary technology that offers a solution to upstream and downstream oil producers for bottom-of-the-barrel upgrading. En i Slurry Technology (EST) is constructing an industrial plant in its Sannazzaro refinery in Italy. The plant is designed to convert 23,000 BPSD of vacuum residue into high quality diesel and other valuable refinery streams such as liquefied petroleum gas, naphtha and jet fuel. EST is an H-addition process characterized by the use of a special homogeneous isothermal intrinsically safe reactor, and of a nano-dispersed non-ageing catalyst. EST converts more than 98 per cent of any type of residues to about 110 per cent volume of light products and distillates or extra heavy oils to high quality bottomless SCO. In typical performance, HDS is greater than 85 per cent, HDM greater than 99 per cent and HDCCR greater than 97 per cent. EST also achieves the target of zero fuel oil - zero coke. 12 refs., 4 tabs., 5 figs.

Assaying embryotoxicity in the test tube: current limitations of the embryonic stem cell test (EST) challenging its applicability domain.

Testing for embryotoxicity in vitro is an attractive alternative to animal experimentation. The embryonic stem cell test (EST) is such a method, and it has been formally validated by the European Centre for the Validation of Alternative Methods. A number of recent studies have underscored the potential of this method. However, the EST performed well below the 78% accuracy expected from the validation study using a new set of chemicals and pharmaceutical compounds, and also of toxicity criteria, tested to enlarge the database of the validated EST as part of the Work Package III of the ReProTect Project funded within the 6th Framework Programme of the European Union. To assess the performance and applicability domain of the EST we present a detailed review of the substances and their effects in the EST being nitrofen, ochratoxin A, D-penicillamine, methylazoxymethanol, lovastatin, papaverine, warfarin, β-aminopropionitrile, dinoseb, furosemide, doxylamine, pravastatin, and metoclopramide. By delineation of the molecular mechanisms of the substances we identify six categories of reasons for misclassifications. Some of these limitations might also affect other in vitro methods assessing embryotoxicity. Substances that fall into these categories need to be included in future validation sets and in validation guidelines for embryotoxicity testing. Most importantly, we suggest conceivable improvements and additions to the EST which will resolve most of the limitations.

Full Text Available Abstract Background Pigeonpea (Cajanus cajan (L. Millsp is one of the major grain legume crops of the tropics and subtropics, but biotic stresses [Fusarium wilt (FW, sterility mosaic disease (SMD, etc.] are serious challenges for sustainable crop production. Modern genomic tools such as molecular markers and candidate genes associated with resistance to these stresses offer the possibility of facilitating pigeonpea breeding for improving biotic stress resistance. Availability of limited genomic resources, however, is a serious bottleneck to undertake molecular breeding in pigeonpea to develop superior genotypes with enhanced resistance to above mentioned biotic stresses. With an objective of enhancing genomic resources in pigeonpea, this study reports generation and analysis of comprehensive resource of FW- and SMD- responsive expressed sequence tags (ESTs. Results A total of 16 cDNA libraries were constructed from four pigeonpea genotypes that are resistant and susceptible to FW ('ICPL 20102' and 'ICP 2376' and SMD ('ICP 7035' and 'TTB 7' and a total of 9,888 (9,468 high quality ESTs were generated and deposited in dbEST of GenBank under accession numbers GR463974 to GR473857 and GR958228 to GR958231. Clustering and assembly analyses of these ESTs resulted into 4,557 unique sequences (unigenes including 697 contigs and 3,860 singletons. BLASTN analysis of 4,557 unigenes showed a significant identity with ESTs of different legumes (23.2-60.3%, rice (28.3%, Arabidopsis (33.7% and poplar (35.4%. As expected, pigeonpea ESTs are more closely related to soybean (60.3% and cowpea ESTs (43.6% than other plant ESTs. Similarly, BLASTX similarity results showed that only 1,603 (35.1% out of 4,557 total unigenes correspond to known proteins in the UniProt database (≤ 1E-08. Functional categorization of the annotated unigenes sequences showed that 153 (3.3% genes were assigned to cellular component category, 132 (2.8% to biological process, and 132 (2

The mining of toxin-like polypeptides from EST database by single residue distribution analysis

Full Text Available Abstract Background Novel high throughput sequencing technologies require permanent development of bioinformatics data processing methods. Among them, rapid and reliable identification of encoded proteins plays a pivotal role. To search for particular protein families, the amino acid sequence motifs suitable for selective screening of nucleotide sequence databases may be used. In this work, we suggest a novel method for simplified representation of protein amino acid sequences named Single Residue Distribution Analysis, which is applicable both for homology search and database screening. Results Using the procedure developed, a search for amino acid sequence motifs in sea anemone polypeptides was performed, and 14 different motifs with broad and low specificity were discriminated. The adequacy of motifs for mining toxin-like sequences was confirmed by their ability to identify 100% toxin-like anemone polypeptides in the reference polypeptide database. The employment of novel motifs for the search of polypeptide toxins in Anemonia viridis EST dataset allowed us to identify 89 putative toxin precursors. The translated and modified ESTs were scanned using a special algorithm. In addition to direct comparison with the motifs developed, the putative signal peptides were predicted and homology with known structures was examined. Conclusions The suggested method may be used to retrieve structures of interest from the EST databases using simple amino acid sequence motifs as templates. The efficiency of the procedure for directed search of polypeptides is higher than that of most currently used methods. Analysis of 39939 ESTs of sea anemone Anemonia viridis resulted in identification of five protein precursors of earlier described toxins, discovery of 43 novel polypeptide toxins, and prediction of 39 putative polypeptide toxin sequences. In addition, two precursors of novel peptides presumably displaying neuronal function were disclosed.

2012-03-01

The cephalochordates, commonly known as amphioxus or lancelets, are now considered the most basal chordate group, and the studies of these organisms therefore offer important insights into various levels of evolutionary biology. In the past two decades, the investigation of amphioxus developmental biology has provided key knowledge for understanding the basic patterning mechanisms of chordates. Comparative genome studies of vertebrates and amphioxus have uncovered clear evidence supporting the hypothesis of two-round whole-genome duplication thought to have occurred early in vertebrate evolution and have shed light on the evolution of morphological novelties in the complex vertebrate body plan. Complementary to the amphioxus genome-sequencing project, a large collection of expressed sequence tags (ESTs) has been generated for amphioxus in recent years; this valuable collection represents a rich resource for gene discovery, expression profiling and molecular developmental studies in the amphioxus model. Here, we review previous EST analyses and available cDNA resources in amphioxus and discuss their value for use in evolutionary and developmental studies. We also discuss the potential advantages of applying high-throughput, next-generation sequencing (NGS) technologies to the field of amphioxus research.

Para una ética y una estética del software libre

Directory of Open Access Journals (Sweden)

Alonso, Andoni

2006-06-01

Full Text Available This paper deals with how an emergent community like hacker´s has developed a code of aestehtic and ethical values in different levels. The history of hackerism is a previous step to understand in a very basic way how code writing has forked in two different paths: free software and open code. Aesthetics can be a way to correlate creative work made by hackers and how avant-garde movements considered their work. From an ethical point of view it is difficult to find an unified agenda for all the different groups involved with free and open software. But this movement represents the emergence of a new ethical approach, retaking older attitudes like the commons.

El presente artículo estudia el modo en que la comunidad hacker ha desarrollado un código propio de valores estéticos y éticos. La historia del «hackerismo » supone un paso previo para la comprensión de cómo la escritura de código se ha bifurcado en dos líneas: el software libre y el código abierto. El estudio de las dimensiones estéticas de estos movimientos puede resultar muy provechoso para correlacionar el trabajo creativo de los hackers y la manera en que éste es considerado por los movimientos de vanguardia. Desde un punto de vista ético, es difícil definir un proyecto común a todos los grupos implicados. Sin embargo, este movimiento representa, en su conjunto, la emergencia de una nueva perspectiva ética que retoma viejas ideas como la del procomún.

2004-11-01

Full Text Available Abstract Background The ongoing efforts to sequence the honey bee genome require additional initiatives to define its transcriptome. Towards this end, we employed the Open Reading frame ESTs (ORESTES strategy to generate profiles for the life cycle of Apis mellifera workers. Results Of the 5,021 ORESTES, 35.2% matched with previously deposited Apis ESTs. The analysis of the remaining sequences defined a set of putative orthologs whose majority had their best-match hits with Anopheles and Drosophila genes. CAP3 assembly of the Apis ORESTES with the already existing 15,500 Apis ESTs generated 3,408 contigs. BLASTX comparison of these contigs with protein sets of organisms representing distinct phylogenetic clades revealed a total of 1,629 contigs that Apis mellifera shares with different taxa. Most (41% represent genes that are in common to all taxa, another 21% are shared between metazoans (Bilateria, and 16% are shared only within the Insecta clade. A set of 23 putative genes presented a best match with human genes, many of which encode factors related to cell signaling/signal transduction. 1,779 contigs (52% did not match any known sequence. Applying a correction factor deduced from a parallel analysis performed with Drosophila melanogaster ORESTES, we estimate that approximately half of these no-match ESTs contigs (22% should represent Apis-specific genes. Conclusions The versatile and cost-efficient ORESTES approach produced minilibraries for honey bee life cycle stages. Such information on central gene regions contributes to genome annotation and also lends itself to cross-transcriptome comparisons to reveal evolutionary trends in insect genomes.

A estética realista dos filmes sobre a ditadura militar no Brasil

2008-12-01

Full Text Available O cinema canaliza em seu aporte uma impressão de realidade baseada na experiência empírica do realizador e da sociedade ao qual ele pertence. Em sua condição de discurso, o cinema, assim como todas as formas narrativas, abrange um enunciado e um espectador. Diferentemente de um romance, a “gramática” cinematográfica é composta por um conjunto de elementos como a imagem, som, música entre outros que, organizados, contam uma história. Entretanto, a forma como estes componentes são gravados em imagens e ordenados numa seqüência narrativa não é única. Desta forma, podemos pensar qual é o propósito de uma escolha estética usual nos filmes Pra frente Brasil e Batismo de Sangue para representar a Ditadura Militar Brasileira.

Cartilaginous fishes are the most ancient group of living jawed vertebrates (gnathostomes) and are, therefore, an important reference group for understanding the evolution of vertebrates. The elephant shark (Callorhinchus milii), a holocephalan cartilaginous fish, has been identified as a model cartilaginous fish genome because of its compact genome (∼910 Mb) and a genome project has been initiated to obtain its whole genome sequence. In this study, we have generated and sequenced full-length enriched cDNA libraries of the elephant shark using the \\'oligo-capping\\' method and Sanger sequencing. A total of 6,778 full-length protein-coding cDNA and 10,701 full-length noncoding cDNA were sequenced from six tissues (gills, intestine, kidney, liver, spleen, and testis) of the elephant shark. Analysis of their polyadenylation signals showed that polyadenylation usage in elephant shark is similar to that in mammals. Furthermore, both coding and noncoding transcripts of the elephant shark use the same proportion of canonical polyadenylation sites. Besides BLASTX searches, protein-coding transcripts were annotated by Gene Ontology, InterPro domain, and KEGG pathway analyses. By comparing elephant shark genes to bony vertebrate genes, we identified several ancient genes present in elephant shark but differentially lost in tetrapods or teleosts. Only ∼6% of elephant shark noncoding cDNA showed similarity to known noncoding RNAs (ncRNAs). The rest are either highly divergent ncRNAs or novel ncRNAs. In addition to full-length transcripts, 30,375 5\\'-ESTs and 41,317 3\\'-ESTs were sequenced and annotated. The clones and transcripts generated in this study are valuable resources for annotating transcription start sites, exon-intron boundaries, and UTRs of genes in the elephant shark genome, and for the functional characterization of protein sequences.

Nos poemas dessas autoras, as imitações da pedra evocam o mysterium tremendum. Mensageiras do sagrado intocável que incita e invade o reino dos mortais, as estátuas parecem resistir à vida aprisionada no mármore com seu tanto de terrífico e fascinante que ponteia o divino e o humano.

The desert locust (Schistocerca gregaria) displays a fascinating type of phenotypic plasticity, designated as 'phase polyphenism'. Depending on environmental conditions, one genome can be translated into two highly divergent phenotypes, termed the solitarious and gregarious (swarming) phase. Although many of the underlying molecular events remain elusive, the central nervous system (CNS) is expected to play a crucial role in the phase transition process. Locusts have also proven to be interesting model organisms in a physiological and neurobiological research context. However, molecular studies in locusts are hampered by the fact that genome/transcriptome sequence information available for this branch of insects is still limited.

Full Text Available BACKGROUND: The desert locust (Schistocerca gregaria displays a fascinating type of phenotypic plasticity, designated as 'phase polyphenism'. Depending on environmental conditions, one genome can be translated into two highly divergent phenotypes, termed the solitarious and gregarious (swarming phase. Although many of the underlying molecular events remain elusive, the central nervous system (CNS is expected to play a crucial role in the phase transition process. Locusts have also proven to be interesting model organisms in a physiological and neurobiological research context. However, molecular studies in locusts are hampered by the fact that genome/transcriptome sequence information available for this branch of insects is still limited. METHODOLOGY: We have generated 34,672 raw expressed sequence tags (EST from the CNS of desert locusts in both phases.

We developed and characterized expressed sequence tags (ESTs)-simple sequence repeats (SSRs) and targeted region amplified polymorphism (TRAP) markers to examine genetic relationships in the persimmon genus Diospyros gene pool. In total, we characterized 14 EST-SSR primer pairs and 36 TRAP primer combinations, which were amplified across 20 germplasms of 4 species in the genus Diospyros. We used various genetic parameters, including effective multiplex ratio (EMR), diversity index (DI), and marker index (MI), to test the utility of these markers. TRAP markers gave higher EMR (24.85) but lower DI (0.33), compared to EST-SSRs (EMR = 3.65, DI = 0.34). TRAP gave a very high MI (8.08), which was about 8 times than the MI of EST-SSR (1.25). These markers were utilized for phylogenetic inference of 20 genotypes of Diospyros kaki Thunb. and allied species, with a result that all kaki genotypes clustered closely and 3 allied species formed an independent group. These markers could be further exploited for large-scale genetic relationship inference.

MuSICa at GRIS: a prototype image slicer for EST at GREGOR

Calcines, A.; Collados, M.; López, R. L.

2013-05-01

This communication presents a prototype image slicer for the 4-m European Solar Telescope (EST) designed for the spectrograph of the 1.5-m GREGOR solar telescope (GRIS). The design of this integral field unit has been called MuSICa (Multi-Slit Image slicer based on collimator-Camera). It is a telecentric system developed specifically for the integral field, high resolution spectrograph of EST and presents multi-slit capability, reorganizing a bidimensional field of view of 80 arcsec^{2} into 8 slits, each one of them with 200 arcsec length × 0.05 arcsec width. It minimizes the number of optical components needed to fulfil this multi-slit capability, three arrays of mirrors: slicer, collimator and camera mirror arrays (the first one flat and the other two spherical). The symmetry of the layout makes it possible to overlap the pupil images associated to each part of the sliced entrance field of view. A mask with only one circular aperture is placed at the pupil position. This symmetric characteristic offers some advantages: facilitates the manufacturing process, the alignment and reduces the costs. In addition, it is compatible with two modes of operation: spectroscopic and spectro-polarimetric, offering a great versatility. The optical quality of the system is diffraction-limited. The prototype will improve the performances of GRIS at GREGOR and is part of the feasibility study of the integral field unit for the spectrographs of EST. Although MuSICa has been designed as a solar image slicer, its concept can also be applied to night-time astronomical instruments (Collados et al. 2010, Proc. SPIE, Vol. 7733, 77330H; Collados et al. 2012, AN, 333, 901; Calcines et al. 2010, Proc. SPIE, Vol. 7735, 77351X)

The existence of an underlying connivance between ethics and aesthetics has been acknowledged ever since ancient times. Here we try to look into this hard and interesting issue from the open horizon of boundary-philosophy, as put forward in my latest publications. The task will be carried out at three stages. The first one is given over to an elucidation of one core concept of ethics, freedom, in an interactive connection with our fore-understanding of our human condition. Then we raise the (Kantian question about how the ethical «symbolically resounds» through art. The third and last stage brings up the subject of the link between ethics and aesthetics on the ground of several examples, both ancient and modern (from the great tragedies and some artistic manifestations of our modernity.

We procured 10000 ESTs and analyzed 267 EST-SSRs markers through computational approach. The average density was one SSR/10.45 kb or 6.4% frequency, wherein trinucleotide repeats (66.74% were the most abundant followed by di- (26.10%, tetra- (4.67%, penta- (1.5%, and hexanucleotide (1.2% repeats. Functional annotations were done and after-effect newly developed 63 EST-SSRs were used for cross transferability, genetic diversity, and bulk segregation analysis (BSA. Out of 63 EST-SSRs, 42 markers were identified owing to their expansion genetics across 20 different plants which amplified 519 alleles at 180 loci with an average of 2.88 alleles/locus and the polymorphic information content (PIC ranged from 0.51 to 0.93 with an average of 0.83. The cross transferability ranged from 25% for wheat to 97.22% for Schlerostachya, with an average of 55.86%, and genetic relationships were established based on diversification among them. Moreover, 10 EST-SSRs were recognized as important markers between bulks of pooled DNA of sugarcane cultivars through BSA. This study highlights the employability of the markers in transferability, genetic diversity in grass species, and distinguished sugarcane bulks.

Full Text Available La yuca (Manihot esculenta constituye la base de la alimentación para más de 1.000 millones de personas en el mundo, consolidándose como el cuarto cultivo más importante en el mundo después del arroz, el maíz y el trigo. La yuca es considerada como un cultivo relativamente tolerante a condiciones de estrés abiótico y biótico, sin embargo estas características se encuentran principalmente en variedades no comerciales. Las estrategias de mejoramiento genético convencional o mediadas por transformación genética representan una alternativa para introducir las características deseadas dentro de las variedades comerciales. Un paso fundamental con miras a acelerar los procesos de mejoramiento genético en yuca requiere el descubrimiento de los respectivos genes relacionados con las características buscadas, para lo cual los ESTs (del inglés Expressed Sequence Tags son una vía rápida para este fin. En este estudio se realizó un análisis de la colección completa de ESTs disponibles en yuca, representada por 80.459 secuencias, los cuales fueron ensamblados en un conjunto de de 29.231 genes únicos (unigen, representado por 10.945 contigs y 18.286 singletones. Estos 29.231 genes únicos pueden representar cerca del 80% de los genes del genoma de yuca. Entre el 5 y 10% de los unigenes de yuca no presentaron similitud con las secuencias presentes en las bases de datos de NCBI y pueden constituir genes específicos de yuca. A un grupo de secuencias del set unigen (29% fue posible asignarles una categoría funcionales de acuerdo al vocabulario Gene Ontology.

2004-02-01

To perform a comprehensive analysis of genes expressed in a model legume, Lotus japonicus, a total of 74472 3'-end expressed sequence tags (EST) were generated from cDNA libraries produced from six different organs. Clustering of sequences was performed with an identity criterion of 95% for 50 bases, and a total of 20457 non-redundant sequences, 8503 contigs and 11954 singletons were generated. EST sequence coverage was analyzed by using the annotated L. japonicus genomic sequence and 1093 of the 1889 predicted protein-encoding genes (57.9%) were hit by the EST sequence(s). Gene content was compared to several plant species. Among the 8503 contigs, 471 were identified as sequences conserved only in leguminous species and these included several disease resistance-related genes. This suggested that in legumes, these genes may have evolved specifically to resist pathogen attack. The rate of gene sequence divergence was assessed by comparing similarity level and functional category based on the Gene Ontology (GO) annotation of Arabidopsis genes. This revealed that genes encoding ribosomal proteins, as well as those related to translation, photosynthesis, and cellular structure were more abundantly represented in the highly conserved class, and that genes encoding transcription factors and receptor protein kinases were abundantly represented in the less conserved class. To make the sequence information and the cDNA clones available to the research community, a Web database with useful services was created at http://www.kazusa.or.jp/en/plant/lotus/EST/.

2013-01-01

The present study was performed to investigate the antitumor and radio sensitizing efficacy of Ganodarma lucidum (G. lucidum) and to evaluate its potential to improve hepatic dysfunction in Ehrlich solid tumor (EST) bearing mice. G. lucidum (100 mg/Kg body weight) was administered orally to EST bearing mice for 15 days before and 15 days after tumor inoculation. Irradiation was carried out the 8th day of tumor inoculation when the diameter of the tumor reached approximately 10 mm. Mice were exposed to fractionated doses of whole body γ-radiation (3x2Gy) at two days interval to attain a total dose of 6 Gy. Mice were divided into 6 groups (15 mice in each group) as follows: normal control, mice treated with G. lucidum for 30 days, EST bearing mice, EST bearing mice exposed to fractionated doses of γ-radiation (2Gy x 3), EST bearing mice treated with G. lucidum for 15 days before and 15 days after tumor inoculation and EST bearing mice received combined treatment radiation and G. lucidum. Five mice from each group were sacrificed, after 18 hr fasting after the last dose of G. lucidum treatment. Blood was collected, liver and tumor were removed for biochemical and histopathological studies. The remaining animals were observed for recording survival percentage and tumor size. In vitro study on Ehrlich Ascites Carcinoma cells showed that the percentage of nonviable cells (NVC%) increase with increasing G. lucidum concentration. The results revealed also that treatment of EST bearing mice with G. lucidum and/or γ- radiation increased the survivability and decrease the tumor size as compared to EST group. The biochemical analysis for EST bearing group recorded an elevation in the activities of lactate dehydrogenase (LDH), asparta amino transferase (AST) and alanine amino transferase (ALT) in the serum. Also, there was an elevation in the concentration of malondialdehyde (MDA), a marker of lipid peroxidation, accompanied by a decrease in superoxide dismutase (SOD

Desinterés y terror. El destino nihilista de la estética occidental en el L'uomo senza contenuto.

Paula Fleisner

2010-07-01

Full Text Available En el mismo año en que se publicaba póstumamente el así llamado “último gran tratado moderno de la disciplina estética”, la Teoría Estética de T. W. Adorno, un joven Giorgio Agamben escribía su contribución, marginal pero decisiva, a un debate muy presente en la filosofía italiana por esos días. Se trata del debate en torno a las relaciones entre el destino nihilista de la metafísica occidental, la estética y la política del que se ocupan entre otros el “pensiero debole” de Gianni Vattimo y el “pensiero negativo” de Massimo Cacciari. Este trabajo tiene como objetivo general analizar las tesis del primer libro de Agamben, L’uomo senza contenuto, en cuanto intento por comprender el proyecto estético de Occidente. Allí se afirma que el ingreso del arte en la dimensión estética con la Modernidad responde al desplazamiento de una consideración de la capacidad pro-ductiva humana (la “inquietante” téchne que permite al hombre llevar una cosa del no-ser al ser hacia una mirada centrada en el punto de vista del espectador que puede apreciar “desinteresadamente” la belleza. Pero este proceso, lejos de ser natural, evidencia una crisis del “hacer” humano en general. Si con Aristóteles podía distinguirse entre póiesis (un hacer aparecer o un traer a la presencia como forma de un saber y praxis (un realizar producto de la voluntad, entendida como apetito, como forma de un actuar, en la Modernidad asistimos al solapamiento de la esfera poiética por la de la praxis y a una progresiva reducción de toda actividad productiva al trabajo que, por reducir al hombre a su desnuda vida biológica, es la dimensión más baja de la vida activa. Teniendo en cuenta este diagnóstico agambeniano, me propongo pensar aquí el lugar central que tendría la estética como disciplina filosófica privilegiada para preguntar por las posibilidades actuales de una nueva póiesis y con ella de una “vita nova” para el hombre.

Full Text Available Tendo por base a filosofia de Herbert Marcuse, o presente artigo objetiva demonstrar a possibilidade de superação do princípio da realidade por meio dos pressupostos fornecidos pela educação estética. Centrada na formação do sujeito como um todo, a educação estética de Marcuse aproxima-se do conceito de Bildung, focando-se na tarefa de trazer de volta à racionalidade moderna as dimensões humanísticas que foram bloqueadas pelo processo da racionalização instrumental. Ao rechaçar a lógica competitiva e dar ênfase à libertação instintual, a educação estética seria capaz ainda de fomentar uma nova estrutura da experiência, que modificaria de modo essencial a relação dos indivíduos com os objetos e com o meio. Desse modo, a educação estética poderia projetar uma tecnologia livre para a realização do seu telos original: a preservação da vida.

Analysis of a normalised expressed sequence tag (EST) library from a key pollinator, the bumblebee Bombus terrestris.

2010-02-15

The bumblebee, Bombus terrestris (Order Hymenoptera), is of widespread importance. This species is extensively used for commercial pollination in Europe, and along with other Bombus spp. is a key member of natural pollinator assemblages. Furthermore, the species is studied in a wide variety of biological fields. The objective of this project was to create a B. terrestris EST resource that will prove to be valuable in obtaining a deeper understanding of this significant social insect. A normalised cDNA library was constructed from the thorax and abdomen of B. terrestris workers in order to enhance the discovery of rare genes. A total of 29'428 ESTs were sequenced. Subsequent clustering resulted in 13'333 unique sequences. Of these, 58.8 percent had significant similarities to known proteins, with 54.5 percent having a "best-hit" to existing Hymenoptera sequences. Comparisons with the honeybee and other insects allowed the identification of potential candidates for gene loss, pseudogene evolution, and possible incomplete annotation in the honeybee genome. Further, given the focus of much basic research and the perceived threat of disease to natural and commercial populations, the immune system of bumblebees is a particularly relevant component. Although the library is derived from unchallenged bees, we still uncover transcription of a number of immune genes spanning the principally described insect immune pathways. Additionally, the EST library provides a resource for the discovery of genetic markers that can be used in population level studies. Indeed, initial screens identified 589 simple sequence repeats and 854 potential single nucleotide polymorphisms. The resource that these B. terrestris ESTs represent is valuable for ongoing work. The ESTs provide direct evidence of transcriptionally active regions, but they will also facilitate further functional genomics, gene discovery and future genome annotation. These are important aspects in obtaining a greater

Telomerase is a ribonucleoprotein complex that adds heximeric repeats called telomeres to the growing ends of chromosomal DNA. Telomerase activity is present in a vast majority of tumors but is repressed in most normal tissues. Human telomerase catalytic subunit gene (hEST2) reverse transcriptase (RT) segment was cloned by PCR according to the sequence published in GeneBank. PCR was used to investigate the expression of the hEST2 RT segment in diverse tumors as well as in various normal tissues. Results indicated that hEST2 RT segment was detectable in tumor cells lines but not in normal cells and tissues. In order to identify the relationship between telomerase and the biological effect of radiation injury, HeLa cells, KB cells and A431 cells were employed to measure the change in telomerase activity after 60 Co-ray irradiation at RNA level and protein level. Quantitative PCR determined that expression of hEST2 RT segment that encodes seven motifs of the human telomeras decreased with increasing dosage of radiation. In addition, a PCR-based telomeric repeat amplification protocol was used to assay telomerase activity after exposure to radiation. The results strongly support the experiments we had made: Telomerase activity decreases with increasing dosage of radiation. We conclude that detection of the hEST2 RT segment by Northern blotting is a new method for detecting telomerase activity. Furthermore, radiation can cause a dose-dependent decrease in telomerase activity. The effect of radiation on telomerase is one possible reason for the death of cancer cells after irradiation.

EVER-EST (European Virtual Environment for Research - Earth Science Themes) is an European H2020 project (2015-2018) aimed at the creation of a Virtual Research Environment (VRE) for the Earth Sciences. The VRE is intended to enhance the ability to collaborate and share knowledge and experience among scientists. One of the innovations of the project is the exploitation of the "Research Object" concept (http://www.rohub.org). Research Objects encapsulate not only data and publications, but also algorithms, codes, results, and workflows that can be stored, shared and re-used. Four scientific communities are involved in the EVER-EST project: land monitoring, natural hazards, marine biology, and the GEO Geohazard Supersites community (http://www.earthobservations.org/gsnl.php). The latter is represented in the project by INGV and the University of Iceland, and has provided user requirements to tailor the VRE to the common needs of the worldwide Supersite communities. To develop and test the VRE we have defined user scenarios and created Research Objects embedding research activities and workflows on the Permanent Supersites Campi Flegrei, Mount Etna and Icelandic Volcanoes (http://vm1.everest.psnc.pl/supersites/). While these Supersites are test sites for the platform, during the last year of the project other Supersites may also be involved to demonstrate the added value of the collaborative environment in research activities aiming to support Disaster Risk Reduction. Using the VRE, scientists are able to collaborate with colleagues located in different parts of the world, in a simple and effective way. This includes being able to remotely access and share data, research results and ideas, to carry out training sessions and discussions, to compare different results and models, and to synthesize many different pieces of information in a single consensus product to be disseminated to end-users. In particular, a further need of the Supersite scientists, which can be

Full Text Available P. minus is an aromatic plant, the leaf of which is widely used as a food additive and in the perfume industry. The leaf also accumulates secondary metabolites that act as active ingredients such as flavonoid. Due to limited genomic and transcriptomic data, the biosynthetic pathway of flavonoids is currently unclear. Identification of candidate genes involved in the flavonoid biosynthetic pathway will significantly contribute to understanding the biosynthesis of active compounds. We have constructed a standard cDNA library from P. minus leaves, and two normalized full-length enriched cDNA libraries were constructed from stem and root organs in order to create a gene resource for the biosynthesis of secondary metabolites, especially flavonoid biosynthesis. Thus, large‑scale sequencing of P. minus cDNA libraries identified 4196 expressed sequences tags (ESTs which were deposited in dbEST in the National Center of Biotechnology Information (NCBI. From the three constructed cDNA libraries, 11 ESTs encoding seven genes were mapped to the flavonoid biosynthetic pathway. Finally, three flavonoid biosynthetic pathway-related ESTs chalcone synthase, CHS (JG745304, flavonol synthase, FLS (JG705819 and leucoanthocyanidin dioxygenase, LDOX (JG745247 were selected for further examination by quantitative RT-PCR (qRT-PCR in different P. minus organs. Expression was detected in leaf, stem and root. Gene expression studies have been initiated in order to better understand the underlying physiological processes.

High and low polymorphisms in simple sequence repeats of expressed sequence tag (EST-SSR) for specific proteins and enzymes, such as β-amylase, cellulose synthase, xyloglucan endotransglucosylase, fructose 1,6-bisphosphate aldolase, and fructose 1,6-bisphosphatase, were used to illustrate the genetic divergence within and between varieties of sugarcane (Saccharum spp.) and to guide the technological paths to optimize ethanol production from lignocellulose biomass. The varieties RB72454, RB867515, RB92579, and SP813250 on the second stage of cutting, all grown in the state of Paraná (PR), and the varieties RB92579 and SP813250 cultured in the PR state and in Northeastern Brazil, state of Pernambuco (PE), were analyzed using five EST-SSR primers for EstC66, EstC67, EstC68, EstC69, and EstC91 loci. Genetic divergence was evident in the EstC67 and EstC69 loci for β-amylase and cellulose synthase, respectively, among the four sugarcane varieties. An extremely high level of genetic differentiation was also detected in the EstC67 locus from the RB82579 and SP813250 varieties cultured in the PR and PE states. High polymorphism in SSR of the cellulose synthase locus may explain the high variability of substrates used in pretreatment and enzymatic hydrolysis processes, which has been an obstacle to effective industrial adaptations.

2015-11-01

A new carboxylic esterase RhEst1 which catalyzes the hydrolysis of (S)-(+)-2,2-dimethylcyclopropanecarboxylate (S-DmCpCe), the key chiral building block of cilastatin, was identified and subsequently crystallized in our previous work. Mutant RhEst1A147I/V148F/G254A was found to show a 5-fold increase in the catalytic activity. In this work, molecular dynamic simulations were performed to elucidate the molecular determinant of the enzyme activity. Our simulations show that the substrate binds much more strongly in the A147I/V148F/G254A mutant than in wild type, with more hydrogen bonds formed between the substrate and the catalytic triad and the oxyanion hole. The OH group of the catalytic residue Ser101 in the mutant is better positioned to initiate the nucleophilic attack on S-DmCpCe. Interestingly, the "170-179" loop which is involved in shaping the catalytic sites and facilitating the product release shows remarkable dynamic differences in the two systems. Based on the simulation results, six residues were identified as potential "hot-spots" for further experimental testing. Consequently, the G126S and R133L mutants show higher catalytic efficiency as compared with the wild type. This work provides molecular-level insights into the substrate binding mechanism of carboxylic esterase RhEst1, facilitating future experimental efforts toward developing more efficient RhEst1 variants for industrial applications.

2014-12-01

Full Text Available An expressed sequence tags (EST resource for tobacco plants (Nicotianatabacum was established using high-throughput sequencing of randomly selected clones from one cDNA library representing a range of plant organs (leaf, stem, root and root base. Over 5000 ESTs were generated from the 3’ ends of 8000 clones, analyzed by BLAST searches and categorized functionally. All annotated ESTs were classified into 18 functional categories, unique transcripts involved in energy were the largest group accounting for 831 (32.32% of the annotated ESTs. After excluding 2450 non-significant tentative unique transcripts (TUTs, 100 unique sequences (1.67% of total TUTs were identified from the N. tabacum database. In the array result two genes strongly related to the tobacco mosaic virus (TMV were obtained, one basic form of pathogenesis-related protein 1 precursor (TBT012G08 and ubiquitin (TBT087G01. Both of them were found in the variety Hongda, some other important genes were classified into two groups, one of these implicated in plant development like those genes related to a photosynthetic process (chlorophyll a-b binding protein, photosystem I, ferredoxin I and III, ATP synthase and a further group including genes related to plant stress response (ubiquitin, ubiquitin-like protein SMT3, glycine-rich RNA binding protein, histones and methallothionein. The interesting finding in this study is that two of these genes have never been reported before in N. tabacum (ubiquitin-like protein SMT3 and methallothionein. The array results were confirmed using quantitative PCR.

2010-11-01

Full Text Available Abstract Background Many species of marine shrimp in the Family Penaeidae, viz. Penaeus (Litopenaeus vannamei, Penaeus monodon, Penaeus (Fenneropenaeus chinensis, and Penaeus (Marsupenaeus japonicus, are animals of economic importance in the aquaculture industry. Yet information about their DNA and protein sequences is lacking. In order to predict their collective proteome, we combined over 270,000 available EST and cDNA sequences from the 4 shrimp species with all protein sequences of Drosophila melanogaster and Caenorhabditis elegans. EST data from 4 other crustaceans, the crab Carcinus maenas, the lobster Homarus americanus (Decapoda, the water flea Daphnia pulex, and the brine shrimp Artemia franciscana were also used. Findings Similarity searches from EST collections of the 4 shrimp species matched 64% of the protein sequences of the fruit fly, but only 45% of nematode proteins, indicating that the shrimp proteome content is more similar to that of an insect than a nematode. Combined results with 4 additional non-shrimp crustaceans increased matching to 78% of fruit fly and 56% of nematode proteins, suggesting that present shrimp EST collections still lack sequences for many conserved crustacean proteins. Analysis of matching data revealed the presence of 4 EST groups from shrimp, namely sequences for proteins that are both fruit fly-like and nematode-like, fruit fly-like only, nematode-like only, and non-matching. Gene ontology profiles of proteins for the 3 matching EST groups were analyzed. For non-matching ESTs, a small fraction matched protein sequences from other species in the UniProt database, including other crustacean-specific proteins. Conclusions Shrimp ESTs indicated that the shrimp proteome is comprised of sub-populations of proteins similar to those common to both insect and nematode models, those present specifically in either model, or neither. Combining small EST collections from related species to compensate for their

Development and Characterization of 1,906 EST-SSR Markers from Unigenes in Jute (Corchorus spp..

Directory of Open Access Journals (Sweden)

Liwu Zhang

Full Text Available Jute, comprising white and dark jute, is the second important natural fiber crop after cotton worldwide. However, the lack of expressed sequence tag-derived simple sequence repeat (EST-SSR markers has resulted in a large gap in the improvement of jute. Previously, de novo 48,914 unigenes from white jute were assembled. In this study, 1,906 EST-SSRs were identified from these assembled uingenes. Among these markers, di-, tri- and tetra-nucleotide repeat types were the abundant types (12.0%, 56.9% and 21.6% respectively. The AG-rich or GA-rich nucleotide repeats were the predominant. Subsequently, a sample of 116 SSRs, located in genes encoding transcription factors and cellulose synthases, were selected to survey polymorphisms among12 diverse jute accessions. Of these, 83.6% successfully amplified at least one fragment and detected polymorphism among the 12diverse genotypes, indicating that the newly developed SSRs are of good quality. Furthermore, the genetic similarity coefficients of all the 12 accessions were evaluated using 97 polymorphic SSRs. The cluster analysis divided the jute accessions into two main groups with genetic similarity coefficient of 0.61. These EST-SSR markers not only enrich molecular markers of jute genome, but also facilitate genetic and genomic researches in jute.

Development, cross-species/genera transferability of novel EST-SSR markers and their utility in revealing population structure and genetic diversity in sugarcane

KAUST Repository

Singh, Ram K.

2013-07-01

Sugarcane (Saccharum spp. hybrid) with complex polyploid genome requires a large number of informative DNA markers for various applications in genetics and breeding. Despite the great advances in genomic technology, it is observed in several crop species, especially in sugarcane, the availability of molecular tools such as microsatellite markers are limited. Now-a-days EST-SSR markers are preferred to genomic SSR (gSSR) as they represent only the functional part of the genome, which can be easily associated with desired trait. The present study was taken up with a new set of 351 EST-SSRs developed from the 4085 non redundant EST sequences of two Indian sugarcane cultivars. Among these EST-SSRs, TNR containing motifs were predominant with a frequency of 51.6%. Thirty percent EST-SSRs showed homology with annotated protein. A high frequency of SSRs was found in the 5\\'UTR and in the ORF (about 27%) and a low frequency was observed in the 3\\'UTR (about 8%). Two hundred twenty-seven EST-SSRs were evaluated, in sugarcane, allied genera of sugarcane and cereals, and 134 of these have revealed polymorphism with a range of PIC value 0.12 to 0.99. The cross transferability rate ranged from 87.0% to 93.4% in Saccharum complex, 80.0% to 87.0% in allied genera, and 76.0% to 80.0% in cereals. Cloning and sequencing of EST-SSR size variant amplicons revealed that the variation in the number of repeat-units was the main source of EST-SSR fragment polymorphism. When 124 sugarcane accessions were analyzed for population structure using model-based approach, seven genetically distinct groups or admixtures thereof were observed in sugarcane. Results of principal coordinate analysis or UPGMA to evaluate genetic relationships delineated also the 124 accessions into seven groups. Thus, a high level of polymorphism adequate genetic diversity and population structure assayed with the EST-SSR markers not only suggested their utility in various applications in genetics and genomics in

Expressed sequence tag (EST) analyses provide a rapid and economical means to identify candidate genes that may be involved in a particular biological process. These ESTs are useful in many Functional Genomics studies. However, the large quantity and complexity of the data generated during an EST sequencing project can make the analysis of this information a daunting task. In an attempt to make this task friendlier, we have developed JUICE, an open source data management system (Apache + PHP + MySQL on Linux), which enables the user to easily upload, organize, visualize and search the different types of data generated in an EST project pipeline. In contrast to other systems, the JUICE data management system allows a branched pipeline to be established, modified and expanded, during the course of an EST project. The web interfaces and tools in JUICE enable the users to visualize the information in a graphical, user-friendly manner. The user may browse or search for sequences and/or sequence information within all the branches of the pipeline. The user can search using terms associated with the sequence name, annotation or other characteristics stored in JUICE and associated with sequences or sequence groups. Groups of sequences can be created by the user, stored in a clipboard and/or downloaded for further analyses. Different user profiles restrict the access of each user depending upon their role in the project. The user may have access exclusively to visualize sequence information, access to annotate sequences and sequence information, or administrative access. JUICE is an open source data management system that has been developed to aid users in organizing and analyzing the large amount of data generated in an EST Project workflow. JUICE has been used in one of the first functional genomics projects in Chile, entitled "Functional Genomics in nectarines: Platform to potentiate the competitiveness of Chile in fruit exportation". However, due to its ability to

EST mining identifies proteins putatively secreted by the anthracnose pathogen Colletotrichum truncatum

Directory of Open Access Journals (Sweden)

Vandenberg Albert

2011-06-01

Full Text Available Abstract Background Colletotrichum truncatum is a haploid, hemibiotrophic, ascomycete fungal pathogen that causes anthracnose disease on many economically important leguminous crops. This pathogen exploits sequential biotrophic- and necrotrophic- infection strategies to colonize the host. Transition from biotrophy to a destructive necrotrophic phase called the biotrophy-necrotrophy switch is critical in symptom development. C. truncatum likely secretes an arsenal of proteins that are implicated in maintaining a compatible interaction with its host. Some of them might be transition specific. Results A directional cDNA library was constructed from mRNA isolated from infected Lens culinaris leaflet tissues displaying the biotrophy-necrotrophy switch of C. truncatum and 5000 expressed sequence tags (ESTs with an average read of > 600 bp from the 5-prime end were generated. Nearly 39% of the ESTs were predicted to encode proteins of fungal origin and among these, 162 ESTs were predicted to contain N-terminal signal peptides (SPs in their deduced open reading frames (ORFs. The 162 sequences could be assembled into 122 tentative unigenes comprising 32 contigs and 90 singletons. Sequence analyses of unigenes revealed four potential groups: hydrolases, cell envelope associated proteins (CEAPs, candidate effectors and other proteins. Eleven candidate effector genes were identified based on features common to characterized fungal effectors, i.e. they encode small, soluble (lack of transmembrane domain, cysteine-rich proteins with a putative SP. For a selected subset of CEAPs and candidate effectors, semiquantitative RT-PCR showed that these transcripts were either expressed constitutively in both in vitro and in planta or induced during plant infection. Using potato virus X (PVX based transient expression assays, we showed that one of the candidate effectors, i. e. contig 8 that encodes a cerato-platanin (CP domain containing protein, unlike CP proteins

Tentative mapping of transcription-induced interchromosomal interaction using chimeric EST and mRNA data.

Directory of Open Access Journals (Sweden)

Per Unneberg

Full Text Available Recent studies on chromosome conformation show that chromosomes colocalize in the nucleus, bringing together active genes in transcription factories. This spatial proximity of actively transcribing genes could provide a means for RNA interaction at the transcript level. We have screened public databases for chimeric EST and mRNA sequences with the intent of mapping transcription-induced interchromosomal interactions. We suggest that chimeric transcripts may be the result of close encounters of active genes, either as functional products or "noise" in the transcription process, and that they could be used as probes for chromosome interactions. We have found a total of 5,614 chimeric ESTs and 587 chimeric mRNAs that meet our selection criteria. Due to their higher quality, the mRNA findings are of particular interest and we hope that they may serve as food for thought for specialists in diverse areas of molecular biology.

Full Text Available Abstract Background Avocado (Persea americana belongs to the Lauraceae family and is an important commercial fruit crop in over 50 countries. The most serious pathogen affecting avocado production is Phytophthora cinnamomi which causes Phytophthora root rot (PRR. Root pathogens such as P. cinnamomi and their interactions with hosts are poorly understood and despite the importance of both the avocado crop and the effect Phytophthora has on its cultivation, there is a lack of molecular knowledge underpinning our understanding of defence strategies against the pathogen. In order to initiate a better understanding of host-specific defence we have generated EST data using 454 pyrosequencing and profiled nine defence-related genes from Pc-infected avocado roots. Results 2.0 Mb of data was generated consisting of ~10,000 reads on a single lane of the GS FLX platform. Using the Newbler assembler 371 contigs were assembled, of which 367 are novel for Persea americana. Genes were classified according to Gene Ontology terms. In addition to identifying root-specific ESTs we were also able to identify and quantify the expression of nine defence-related genes that were differentially regulated in response to P. cinnamomi. Genes such as metallothionein, thaumatin and the pathogenesis related PsemI, mlo and profilin were found to be differentially regulated. Conclusions This is the first study in elucidating the avocado root transcriptome as well as identifying defence responses of avocado roots to the root pathogen P. cinnamomi. Our data is currently the only EST data that has been generated for avocado rootstocks, and the ESTs identified in this study have already been useful in identifying defence-related genes as well as providing gene information for other studies looking at processes such as ROS regulation as well as hypoxia in avocado roots. Our EST data will aid in the elucidation of the avocado transcriptome and identification of markers for improved

The adzuki bean (Vigna angularis (Ohwi) Ohwi and Ohashi) is an important grain legume of Asia. It is cultivated mainly in China, Japan and Korea. Despite its importance, few genomic resources are available for molecular genetic research of adzuki bean. In this study, we developed EST-SSR markers for the adzuki bean through next-generation sequencing. More than 112 million high-quality cDNA sequence reads were obtained from adzuki bean using Illumina paired-end sequencing technology, and the sequences were de novo assembled into 65,950 unigenes. The average length of the unigenes was 1,213 bp. Among the unigenes, 14,547 sequences contained a unique simple sequence repeat (SSR) and 3,350 sequences contained more than one SSR. A total of 7,947 EST-SSRs were identified as potential molecular markers, with mono-nucleotide A/T repeats (99.0%) as the most abundant motif class, followed by AG/CT (68.4%), AAG/CTT (30.0%), AAAG/CTTT (26.2%), AAAAG/CTTTT (16.1%), and AACGGG/CCCGTT (6.0%). A total of 500 SSR markers were randomly selected for validation, of which 296 markers produced reproducible amplicons with 38 polymorphic markers among the 32 adzuki bean genotypes selected from diverse geographical locations across China. The large number of SSR-containing sequences and EST-SSR markers will be valuable for genetic analysis of the adzuki bean and related Vigna species.

Determinação de regiões de órbitas diretas estáveis ao redor da Lua

Neste Trabalho estamos investigando regiões do sistema Terra-Lua que contêm órbitas diretas estáveis ao redor da Lua visando a utilização destas órbitas em futuras missões de veículos espaciais como alternativas de trajetórias com baixo custo de manutenção. Adotando-se o problema restrito de três corpos, Terra-Lua-partícula, a localização e a extensão destas regiões de estabilidade foram investigadas numericamente considerando como estável toda órbita que permanece ao redor a Lua por, no mínimo, 1000 dias com energia de dois corpos da partícula em relação à Lua negativa. A estabilidade de tais regiões está associada a duas famílias de órbitas periódicas simples H1 e H2 e a órbitas quase-periódicas associadas a elas. Uma vez identificadas as regiões de estabilidade passamos a analisá-las introduzindo, paulatinamente, outras interações relevantes ao sistema como as perturbações do Sol (via problema restrito de quatro corpos), das marés, da pressão de radiação e do achatamento terrestre. Os resultados encontrados até o momento mostram que a perturbação do Sol é a única que reduz significativamente o tamanho das regiões de estabilidade. Também estamos investigando o comportamento de tais regiões quando características intrínsecas do sistema como as excentricidades das órbitas da Terra e da Lua e a inclinação da órbita Lua são consideradas. Com este estudo estamos reunindo informações que nos permitirão compreender a evolução das regiões de estabilidade no sistema Terra-Lua, bem como estabelecer parâmetros adequados para a utilização das trajetórias estáveis em futuras missões espaciais.

Full Text Available El frecuente hallazgo de restos humanos desarticulados y dispersos en sitios de la región Este del territorio uruguayo da lugar a la necesidad de recurrir en muchos casos a métodos alternativos de determinación de sexo, basados en análisis discriminantes. Las muestras de las que se parte en estos análisis son ya de poblaciones actuales, ya de poblaciones prehistóricas distintas a las representadas en el registro arqueológico uruguayo. Al determinar el número mínimo de individuos de un conjunto disperso, la edad y el sexo de los individuos representados cobran gran utilidad, y la precisión de los métodos de determinación de sexo basados en piezas aisladas se vuelve crucial. Este trabajo presenta la evaluación de 24 ecuaciones discriminantes canónicas sobre medidas de 7 huesos, en una muestra arqueológica de 15 individuos de dos sitios con estructuras monticulares ("cerritos de indios" del Este Uruguayo. El sexo de los esqueletos fue determinado anteriormente mediante métodos basados en la pelvis, el cráneo, o ambos. Los métodos evaluados presentaron grados de exactitud general de entre el 30 y el 100 por ciento, sin una dirección particular en los errores de clasificación. Esto pone de relieve la necesidad de revisar las ecuaciones utilizadas, recurriendo ya sea a una reelaboración de los coeficientes utilizados, o a un desplazamiento de los puntos de corte.

Full Text Available Os estudantes de graduação do curso de Psicologia do Instituto de Psicologia da Universidade de São Paulo, ao cursarem as disciplinas relacionadas à área da Psicologia Escolar, realizam estágios em instituições educativas. Imbuídos de uma postura crítica, os estagiários entram em contato com demandas de tratamento, prevenção e adaptação e compreendem a produção histórica destas. Todavia, em muitos momentos, os estagiários julgam essas demandas como se fossem equivocadas e, dessa forma, não conseguem perceber a multiplicidade de elementos que as constituem e as formas para agir em sua produção. O objetivo deste artigo é apresentar um percurso de trabalho enfatizando as estratégias criadas para dar conta de um dos desafios que se apresentam no grupo de supervisão: intervir nesse momento no qual os estagiários consideram o funcionamento da escola como algo exterior a eles. As estratégias criadas indicam que a desconstrução necessária na formação dos estudantes de Psicologia para que aprendam a intervir nos processos institucionais vividos durante os estágios requer, também, a desconstrução de uma forma de pensar que cria um suposto sujeito fora do diagrama de forças em que o processo do estágio faz parte.

EST analysis of the scaly green flagellate Mesostigma viride (Streptophyta: Implications for the evolution of green plants (Viridiplantae

2006-02-01

Full Text Available Abstract Background The Viridiplantae (land plants and green algae consist of two monophyletic lineages, the Chlorophyta and the Streptophyta. The Streptophyta include all embryophytes and a small but diverse group of freshwater algae traditionally known as the Charophyceae (e.g. Charales, Coleochaete and the Zygnematales. The only flagellate currently included in the Streptophyta is Mesostigma viride Lauterborn. To gain insight into the genome evolution in streptophytes, we have sequenced 10,395 ESTs from Mesostigma representing 3,300 independent contigs and compared the ESTs of Mesostigma with available plant genomes (Arabidopsis, Oryza, Chlamydomonas, with ESTs from the bryophyte Physcomitrella, the genome of the rhodophyte Cyanidioschyzon, the ESTs from the rhodophyte Porphyra, and the genome of the diatom Thalassiosira. Results The number of expressed genes shared by Mesostigma with the embryophytes (90.3 % of the expressed genes showing similarity to known proteins is higher than with Chlamydomonas (76.1 %. In general, cytosolic metabolic pathways, and proteins involved in vesicular transport, transcription, regulation, DNA-structure and replication, cell cycle control, and RNA-metabolism are more conserved between Mesostigma and the embryophytes than between Mesostigma and Chlamydomonas. However, plastidic and mitochondrial metabolic pathways, cytoskeletal proteins and proteins involved in protein folding are more conserved between Mesostigma and Chlamydomonas than between Mesostigma and the embryophytes. Conclusion Our EST-analysis of Mesostigma supports the notion that this organism should be a suitable unicellular model for the last flagellate common ancestor of the streptophytes. Mesostigma shares more genes with the embryophytes than with the chlorophyte Chlamydomonas reinhardtii, although both organisms are flagellate unicells. Thus, it seems likely that several major physiological changes (e.g. in the regulation of photosynthesis

Taraxacum koksaghyz Rodin (TKS) has been studied in many occasions as a possible alternative source for natural rubber production of good quality and for inulin production. Some tire companies are already testing TKS tire prototypes. There are also many investigations on the production of bio-fuels from inulin and inulin applications for health improvement and in the food industry. A limited amount of genomic resources exist for TKS and particularly no genetic linkage map is available in this species. We have constructed the first TKS genetic linkage map based on AFLP, COS, SSR and EST-SSR markers. The integrated linkage map with eight linkage groups (LG), representing the eight chromosomes of Russian dandelion, has 185 individual AFLP markers from parent 1, 188 individual AFLP markers from parent 2, 75 common AFLP markers and 6 COS, 1 SSR and 63 EST-SSR loci. Blasting the EST-SSR sequences against known sequences from lettuce allowed a partial alignment of our TKS map with a lettuce map. Blast searches against plant gene databases revealed some homologies with useful genes for downstream applications in the future.

2006-11-01

Full Text Available Abstract Background Expressed sequence tag (EST analyses provide a rapid and economical means to identify candidate genes that may be involved in a particular biological process. These ESTs are useful in many Functional Genomics studies. However, the large quantity and complexity of the data generated during an EST sequencing project can make the analysis of this information a daunting task. Results In an attempt to make this task friendlier, we have developed JUICE, an open source data management system (Apache + PHP + MySQL on Linux, which enables the user to easily upload, organize, visualize and search the different types of data generated in an EST project pipeline. In contrast to other systems, the JUICE data management system allows a branched pipeline to be established, modified and expanded, during the course of an EST project. The web interfaces and tools in JUICE enable the users to visualize the information in a graphical, user-friendly manner. The user may browse or search for sequences and/or sequence information within all the branches of the pipeline. The user can search using terms associated with the sequence name, annotation or other characteristics stored in JUICE and associated with sequences or sequence groups. Groups of sequences can be created by the user, stored in a clipboard and/or downloaded for further analyses. Different user profiles restrict the access of each user depending upon their role in the project. The user may have access exclusively to visualize sequence information, access to annotate sequences and sequence information, or administrative access. Conclusion JUICE is an open source data management system that has been developed to aid users in organizing and analyzing the large amount of data generated in an EST Project workflow. JUICE has been used in one of the first functional genomics projects in Chile, entitled "Functional Genomics in nectarines: Platform to potentiate the competitiveness of Chile in

Full Text Available Antecedentes y Objetivos. La liposucción es una técnica frecuente en el contexto de una abdominoplastia estética, pero puede ser causa de una seria complicación como es la perforación de una víscera intrabdominal, cuando la presencia de una hernia de pared no ha sido diagnosticada oportunamente. La ecografía es la primera opción como estudio preoperatorio y la tomografía axial computerizada (TAC es secundaria en pacientes obesos. Describimos la hernioplastia sin uso de material aloplástico y la reconstrucción del ombligo cuando se debe eliminar la cicatriz umbilical, todo ello dentro del marco de una abdominoplastia estética. Pacientes y Método. Revisamos entre enero de 2005 y diciembre de 2012, 104 pacientes sometidas a abdominoplastia estética en las que se solicitó en el preoperatorio ecografía y/o TAC de pared abdominal. Resultados. El 30% de las pacientes pertenecían al Tipo III y el 70% al Tipo IV según clasificación de Matarasso. El 27% presentaban hernia de pared abdominal: hernia umbilical directa 26%; hernia umbilical indirecta 33%; hernia epigástrica 37% y hernia infraumbilical 4%. De las ecografías solicitadas obtuvimos 25% diagnósticos positivos; 3% falsos negativos y 72% verdaderos negativos. De las TAC obtuvimos 25% positivos y 75% negativos. Conclusiones. La ecografía de la pared abdominal es útil pero insuficiente para el diagnóstico preoperatorio de hernia de pared abdominal cuando se va a realizar una abdominoplastia estética, debido a la ocurrencia de falsos negativos. La TAC es el complemento adecuado para los casos de difícil diagnóstico.

Wang, Hongtao; Li, Guisheng; Kwon, Woo-Saeng; Yang, Deok-Chun

2016-06-04

Panax ginseng is one of the most valuable medicinal plants in the Orient. The low level of genetic variation has limited the application of molecular markers for cultivar authentication and marker-assisted selection in cultivated ginseng. To exploit DNA polymorphism within ginseng cultivars, ginseng expressed sequence tags (ESTs) were searched against the potential intron polymorphism (PIP) database to predict the positions of introns. Intron-flanking primers were then designed in conserved exon regions and used to amplify across the more variable introns. Sequencing results showed that single nucleotide polymorphisms (SNPs), as well as indels, were detected in four EST-derived introns, and SNP markers specific to "Gopoong" and "K-1" were first reported in this study. Based on cultivar-specific SNP sites, allele-specific polymerase chain reaction (PCR) was conducted and proved to be effective for the authentication of ginseng cultivars. Additionally, the combination of a simple NaOH-Tris DNA isolation method and real-time allele-specific PCR assay enabled the high throughput selection of cultivars from ginseng fields. The established real-time allele-specific PCR assay should be applied to molecular authentication and marker assisted selection of P. ginseng cultivars, and the EST intron-targeting strategy will provide a potential approach for marker development in species without whole genomic DNA sequence information.

Orchardgrass (Dactylis glomerata L.), is a well-known perennial forage species; however, rust diseases have caused a noticeable reduction in the quality and production of orchardgrass. In this study, genetic diversity was assessed and the marker-trait associations for rust were examined using 18 EST-SSR and 21 SCoT markers in 75 orchardgrass accessions. A high level of genetic diversity was detected in orchardgrass with an average genetic diversity index of 0.369. For the EST-SSR and SCoT markers, 164 and 289 total bands were obtained, of which 148 (90.24%) and 272 (94.12%) were polymorphic, respectively. Results from an AMOVA analysis showed that more genetic variance existed within populations (87.57%) than among populations (12.43%). Using a parameter marker index, the efficiencies of the EST-SSR and SCoT markers were compared to show that SCoTs have higher marker efficiency (8.07) than EST-SSRs (4.82). The results of a UPGMA cluster analysis and a STRUCTURE analysis were both correlated with the geographic distribution of the orchardgrass accessions. Linkage disequilibrium analysis revealed an average r² of 0.1627 across all band pairs, indicating a high extent of linkage disequilibrium in the material. An association analysis between the rust trait and 410 bands from the EST-SSR and SCoT markers using TASSEL software revealed 20 band panels were associated with the rust trait in both 2011 and 2012. The 20 bands obtained from association analysis could be used in breeding programs for lineage selection to prevent great losses of orchardgrass caused by rust, and provide valuable information for further association mapping using this collection of orchardgrass.

Field Punta del Este (TPE) is constituted by a series of gneisses and migmatites formed in the range of 1000 and 900 Ma, and have been intensely reworked during Rio Doce orogeny (ca. 600-500 Ma). This cortical segment represents high-grade metamorphic terrain, correlatable with complex gneiss Southwest Africa, particularly with Kibariáno Belt - Namaqualanos recognized in the southwestern portion of Africa (Namibia). U-Pb zircon ages in tonalite granitoids indicate values ​​between 1000 and 900 Ma and were interpreted as indicating the time of generation of these rocks. This should also be the age of high-grade metamorphism that affected a large part of the gneissic rocks of the region. Moreover, the anatectic related mobilized leucosomes ages of migmatites gave ca. 520-540 Ma, indicating that the metamorphic conditions (overlapping) during the Rio Doce orogeny reached at least the amphibolite facies. The metasedimentary cover TPE occurs in the vicinity of the towns of La Paloma Rocha. These are represented by a siliciclastic metasedimentary sequence represented by Rocha Formation. Despite the poly phase deformation and low grade metamorphism affecting this training, primary structures are common such as stratification plano-parallel, cross-bedding, hummock y and massive levels with gradational stratification

This study was conducted to determine the physiologic and skeletal response to exogenous equine somatotropin (eST) in two-year-old horses in race training. Sixteen Quarter Horse geldings were paired by age (ave. age=26 months), and one horse from each pair was assigned at random to either the eST treatment group or the control. The experiment was conducted over 112 days during which the horses were broke to ride and trained on a dirt track in a regimen typical for racehorses in training. Radiographs were taken of the left third metacarpal on day 0,28, 42, 56, 70, 84 and 112. Jugular blood samples were collected every 14 days and analyzed for calcium (Ca), phosphorous (P), osteocalcin, 25-dihydroxyvitamin D (Vit D), parathyroid hormone (PTH), insulin-like growth factor-I (IGF-I) and growth hormone (GH). Daily injections of eST were well tolerated and resulted in no observed side effects. There was a trend (P= .14) for increased plasma GH concentrations in the treated horses as the trial progressed. Plasma IGF-I concentrations were increased (P .05). In this study, administration of eST was effective in elevating plasma IGF-I, which is stimulatory to osteoblasts, and serum osteocalcin, which is a product of osteoblastic activity

Toxocara canis is a widespread intestinal nematode parasite of dogs, which can also cause disease in humans. We employed an expressed sequence tag (EST) strategy in order to study gene-expression including development, digestion and reproduction of T. canis. ESTs provided a rapid way to identify genes, particularly in organisms for which we have very little molecular information. In this study, a cDNA library was constructed from a female adult of T. canis and 215 high-quality ESTs from 5'-ends of the cDNA clones representing 79 unigenes were obtained. The titer of the primary cDNA library was 1.83×10(6)pfu/mL with a recombination rate of 99.33%. Most of the sequences ranged from 300 to 900bp with an average length of 656bp. Cluster analysis of these ESTs allowed identification of 79 unique sequences containing 28 contigs and 51 singletons. BLASTX searches revealed that 18 unigenes (22.78% of the total) or 70 ESTs (32.56% of the total) were novel genes that had no significant matches to any protein sequences in the public databases. The rest of the 61 unigenes (77.22% of the total) or 145 ESTs (67.44% of the total) were closely matched to the known genes or sequences deposited in the public databases. These genes were classified into seven groups based on their known or putative biological functions. We also confirmed the gene expression patterns of several immune-related genes using RT-PCR examination. This work will provide a valuable resource for the further investigations in the stage-, sex- and tissue-specific gene transcription or expression. Copyright © 2011. Published by Elsevier Inc.

2008-05-01

Full Text Available Abstract Background Vitis vinifera (V. vinifera is the primary grape species cultivated for wine production, with an industry valued annually in the billions of dollars worldwide. In order to sustain and increase grape production, it is necessary to understand the genetic makeup of grape species. Here we performed mRNA profiling using Massively Parallel Signature Sequencing (MPSS and combined it with available Expressed Sequence Tag (EST data. These tag-based technologies, which do not require a priori knowledge of genomic sequence, are well-suited for transcriptional profiling. The sequence depth of MPSS allowed us to capture and quantify almost all the transcripts at a specific stage in the development of the grape berry. Results The number and relative abundance of transcripts from stage II grape berries was defined using Massively Parallel Signature Sequencing (MPSS. A total of 2,635,293 17-base and 2,259,286 20-base signatures were obtained, representing at least 30,737 and 26,878 distinct sequences. The average normalized abundance per signature was ~49 TPM (Transcripts Per Million. Comparisons of the MPSS signatures with available Vitis species' ESTs and a unigene set demonstrated that 6,430 distinct contigs and 2,190 singletons have a perfect match to at least one MPSS signature. Among the matched sequences, ESTs were identified from tissues other than berries or from berries at different developmental stages. Additional MPSS signatures not matching to known grape ESTs can extend our knowledge of the V. vinifera transcriptome, particularly when these data are used to assist in annotation of whole genome sequences from Vitis vinifera. Conclusion The MPSS data presented here not only achieved a higher level of saturation than previous EST based analyses, but in doing so, expand the known set of transcripts of grape berries during the unique stage in development that immediately precedes the onset of ripening. The MPSS dataset also revealed

Estética como fisiologia aplicada em Nietzsche

Renato Bittencourt

2010-07-01

Full Text Available A proposta deste artigo consiste em pensarmos a relação intrínseca que Nietzsche estabelece entre a estética e a compreensão orgânica da vida humana, associada diretamente a uma perspectiva fisiológica. Cabe ressaltar que a noção de fisiologia em Nietzsche não se fundamenta em parâmetros puramente biológicos ou materiais, mas envolve todos os atos criativos do indivíduo. Por conseguinte, para compreendermos de forma precisa a realização da criatividade artística é de suma importância que se faça valer a importância da fisiologia do artista no processo de elaboração da obra de arte. Onde os instintos vitais se encontram em declínio existencial, haverá uma obra de arte decadente; onde os instintos vitais manifestam exuberância, capacidade de assimilação e saúde, haverá uma glorificação da existência através da arte.

Así, en la estética arltiana de una literatura que encierra “la viol encia de un ‘cross’ a la mandíbula”, definida en las palabras preliminares a Los lanzallamas, se introducen algunos rasgos que provienen del modernismo y del imaginario decadente, en muchos aspectos, muy criticados por el propio escritor. En este marco, se analiza, en primer lugar, “Jehová” (1918, el primer cuento que publicó, cuya construcción evidencia lecturas de fuerte matriz modernista. Luego, se estudia el modo en que Arlt intenta separarse del modernismo-decadentismo en sus textos programáticos, sus novelas y sus primeras narraciones, y la forma en que, de todas maneras, se retoman en su literatura ciertos elementos que remiten visiblemente a la estética en cuestión. Finalmente, indagamos cómo, cuando en Arlt puede observarse una pretensión de “estilo alto”, aparece el modernismo

The "living fossil" Metasequoia glyptostroboides Hu et Cheng, commonly known as dawn redwood or Chinese redwood, is the only living species in the genus and is valued for its essential oil and crude extracts that have great potential for anti-fungal activity. Despite its paleontological significance and economical value as a rare relict species, genomic resources of Metasequoia are very limited. In order to gain insight into the molecular mechanisms behind the formation of reproductive buds and the transition from vegetative phase to reproductive phase in Metasequoia, we performed sequencing of expressed sequence tags from Metasequoia vegetative buds and female buds. By using the 454 pyrosequencing technology, a total of 1,571,764 high-quality reads were generated, among which 733,128 were from vegetative buds and 775,636 were from female buds. These EST reads were clustered and assembled into 114,124 putative unique transcripts (PUTs) with an average length of 536 bp. The 97,565 PUTs that were at least 100 bp in length were functionally annotated by a similarity search against public databases and assigned with Gene Ontology (GO) terms. A total of 59 known floral gene families and 190 isotigs involved in hormone regulation were captured in the dataset. Furthermore, a set of PUTs differentially expressed in vegetative and reproductive buds, as well as SSR motifs and high confidence SNPs, were identified. This is the first large-scale expressed sequence tags ever generated in Metasequoia and the first evidence for floral genes in this critically endangered deciduous conifer species.

Full Text Available Abstract Background The southern cattle tick, Rhipicephalus (Boophilus microplus, is an economically important parasite of cattle and can transmit several pathogenic microorganisms to its cattle host during the feeding process. Understanding the biology and genomics of R. microplus is critical to developing novel methods for controlling these ticks. Results We present a global comparative genomic analysis of a gene index of R. microplus comprised of 13,643 unique transcripts assembled from 42,512 expressed sequence tags (ESTs, a significant fraction of the complement of R. microplus genes. The source material for these ESTs consisted of polyA RNA from various tissues, lifestages, and strains of R. microplus, including larvae exposed to heat, cold, host odor, and acaricide. Functional annotation using RPS-Blast analysis identified conserved protein domains in the conceptually translated gene index and assigned GO terms to those database transcripts which had informative BlastX hits. Blast Score Ratio and SimiTri analysis compared the conceptual transcriptome of the R. microplus database to other eukaryotic proteomes and EST databases, including those from 3 ticks. The most abundant protein domains in BmiGI were also analyzed by SimiTri methodology. Conclusion These results indicate that a large fraction of BmiGI entries have no homologs in other sequenced genomes. Analysis with the PartiGene annotation pipeline showed 64% of the members of BmiGI could not be assigned GO annotation, thus minimal information is available about a significant fraction of the tick genome. This highlights the important insights in tick biology which are likely to result from a tick genome sequencing project. Global comparative analysis identified some tick genes with unexpected phylogenetic relationships which detailed analysis attributed to gene losses in some members of the animal kingdom. Some tick genes were identified which had close orthologues to mammalian genes

Full Text Available Abstract Background Lepeophtheirus salmonis is an ectoparasitic copepod feeding on skin, mucus and blood from salmonid hosts. Initial analysis of EST sequences from pre adult and adult stages of L. salmonis revealed a large proportion of novel transcripts. In order to link unknown transcripts to biological functions we have combined EST sequencing and microarray analysis to characterize female salmon louse transcriptomes during post molting maturation and egg production. Results EST sequence analysis shows that 43% of the ESTs have no significant hits in GenBank. Sequenced ESTs assembled into 556 contigs and 1614 singletons and whenever homologous genes were identified no clear correlation with homologous genes from any specific animal group was evident. Sequence comparison of 27 L. salmonis proteins with homologous proteins in humans, zebrafish, insects and crustaceans revealed an almost identical sequence identity with all species. Microarray analysis of maturing female adult salmon lice revealed two major transcription patterns; up-regulation during the final molting followed by down regulation and female specific up regulation during post molting growth and egg production. For a third minor group of ESTs transcription decreased during molting from pre-adult II to immature adults. Genes regulated during molting typically gave hits with cuticula proteins whilst transcripts up regulated during post molting growth were female specific, including two vitellogenins. Conclusion The copepod L.salmonis contains high a level of novel genes. Among analyzed L.salmonis proteins, sequence identities with homologous proteins in crustaceans are no higher than to homologous proteins in humans. Three distinct processes, molting, post molting growth and egg production correlate with transcriptional regulation of three groups of transcripts; two including genes related to growth, one including genes related to egg production. The function of the regulated

Full Text Available Diante do escasso conhecimento morfofisiológico do trato digestório do Tamandua tetradactyla, este trabalho pretendeu esclarecer a morfologia do estômago dessa espécie. Utilizaram-se seis espécimes, sendo três machos e três fêmeas jovens, provenientes da área de Mina Bauxita Paragominas - PA, doados, após morte por atropelamento, ao Laboratório de Pesquisa Morfológica Animal (LaPMA. Os animais foram fixados com solução aquosa de formaldeído (10%, seguido de dissecação, avaliação da topografia do estômago, com posterior descrição, mensuração e coleta de material para microscopia. As análises topográfica e macroscópica revelaram que o estômago, unicavitário, com presença de pequena e grande curvaturas, estava localizado no antímero esquerdo da cavidade abdominal, ligado cranialmente ao esôfago e caudalmente ao duodeno, e apresentou um aumento de superfície na região pilórica (toro pilórico. Histologicamente, era constituído por epitélio colunar simples (região glandular, epitélio estratificado pavimentoso (região aglandular, lâmina própria, muscular da mucosa, submucosa, muscular circular interna, muscular longitudinal externa e serosa. A região do piloro apresentou um grande espessamento da camada muscular da mucosa, e foram observadas nesta região fossetas gástricas profundas. O estômago de T. tetradactyla revelou características morfológicas macroscópicas e histológicas semelhantes às espécies domésticas e selvagens.

Full Text Available RESUMEN: El presente texto reivindica el pensamiento estético de Theodor W. Adorno, argumentando la actualidad de su legado más allá de su valor historiográfico como testigo crítico del arte moderno, con una especial atención a elementos que han sido malinterpretados en su recepción, como las aporías que constituyen la división entre alta cultura y cultura de masas, el diálogo de la estética adorniana con la evolución de las fuerzas productivas artísticas o su metodología teórica, que plantea exigencias cruciales a la estética y la teoría del arte como disciplinas académicas.ABSTRACT: The article vindicates Adorno’s aesthetic thought by presenting the value of Adorno’s legacy beyond its historiographic value as a critical witness of contemporary art. The article pays special attention to the aspects that have traditionally been misinterpreted in the reception of Adorno’s writings, such as the aporias that make up the division between high and low culture, the dialogue between Adorno’s aesthetics and the evolution of artistic forces, or his theoretical methodology, which raises crucial issues for the field of aesthetics and art theory as academic disciplines.

Full Text Available The structure and stability of fatty acid monolayers spread on aqueous solutions with ethanol has been studied. The experiments were carried out isothermically using a commercial Langmuir balance (Lauda. Monolayers exhibit solid or condensed liquid structure depending of the ethanol concentration in the subphase. Temperature has not a significant influence on the monolayer. Structure there is a loss of stearic acid film through solution into the adjacent subphase. This loss is increased with the temperature and ethanol concentration in the subphase.

Monocapas de ácidos grasos. I. Acido esteárico sobre disoluciones acuosas de etanol. Se ha estudiado la estructura y estabilidad de monocapas de ácido esteárico esparcidas sobre disoluciones acuosas que contienen etanol. Las experiencias se han realizado en una balanza de superficie comercial tipo Langmuir y se ha operado en condiciones isotérmicas. Las monocapas presentan estructuras de tipo sólida o de líquido condensado en función de la concentración de etanol en la subfase. La estructura que adopta la monocapa es prácticamente independiente de la temperatura. La pérdida de moléculas de ácido esteárico de la monocapa por disolución en la subfase se incrementa a los valores más elevados de temperatura y de concentración de etanol.

Full Text Available A sociedade romana produziu estátuas abundantemente, como argumenta Stewart (2003:118. As suas funções eram diversas e vários os seus propósitos. Neste artigo, buscaremos apresentar a importância político-cultural das estátuas imperiais na sociedade romana do século IV d.C. a partir da compreensão da gravidade dos acontecimentos ocorridos durante a deflagração de um levante que ficou conhecido, na historiografia, como Levante das Estátuas. Neste levante, estátuas imperiais foram destruídas. Para tanto, utilizaremos a documentação legada por um presbítero, João Crisóstomo, que pronunciou, tradicionalmente, 21 homilias que a historiografia vinculou ao Levante das Estátuas.Roman society abundantly produced statues as discussed by Stewart (2003:118. Their functions were diverse and purposes innumerous. In this article, we seek to present the politico-cultural importance of the imperial statues in Roman society in the 4th century AD from our understanding of the seriousness of the events that occurred during the outburst of an insurrection that was better known in historiography as the Revolt of the Statues, where imperial statues were mutilated and destroyed. We therefore used documents linked to a Presbyterian, John Chrysostom, who preached traditionally 21 homilies that the historiography linked to the Revolt of the Statues.

Background The globe artichoke (Cynara cardunculus var. scolymus L.) is a significant crop in the Mediterranean basin. Despite its commercial importance and its both dietary and pharmaceutical value, knowledge of its genetics and genomics remains scant. Microsatellite markers have become a key tool in genetic and genomic analysis, and we have exploited recently acquired EST (expressed sequence tag) sequence data (Composite Genome Project - CGP) to develop an extensive set of microsatellite markers. Results A unigene assembly was created from over 36,000 globe artichoke EST sequences, containing 6,621 contigs and 12,434 singletons. Over 12,000 of these unigenes were functionally assigned on the basis of homology with Arabidopsis thaliana reference proteins. A total of 4,219 perfect repeats, located within 3,308 unigenes was identified and the gene ontology (GO) analysis highlighted some GO term's enrichments among different classes of microsatellites with respect to their position. Sufficient flanking sequence was available to enable the design of primers to amplify 2,311 of these microsatellites, and a set of 300 was tested against a DNA panel derived from 28 C. cardunculus genotypes. Consistent amplification and polymorphism was obtained from 236 of these assays. Their polymorphic information content (PIC) ranged from 0.04 to 0.90 (mean 0.66). Between 176 and 198 of the assays were informative in at least one of the three available mapping populations. Conclusion EST-based microsatellites have provided a large set of de novo genetic markers, which show significant amounts of polymorphism both between and within the three taxa of C. cardunculus. They are thus well suited as assays for phylogenetic analysis, the construction of genetic maps, marker-assisted breeding, transcript mapping and other genomic applications in the species.

Full Text Available Abstract Background The western African clawed frog Xenopus tropicalis is an anuran amphibian species now used as model in vertebrate comparative genomics. It provides the same advantages as Xenopus laevis but is diploid and has a smaller genome of 1.7 Gbp. Therefore X. tropicalis is more amenable to systematic transcriptome surveys. We initiated a large-scale partial cDNA sequencing project to provide a functional genomics resource on genes expressed in the nervous system during early embryogenesis and metamorphosis in X. tropicalis. Results A gene index was defined and analysed after the collection of over 48,785 high quality sequences. These partial cDNA sequences were obtained from an embryonic head and retina library (30,272 sequences and from a metamorphic brain and spinal cord library (27,602 sequences. These ESTs are estimated to represent 9,693 transcripts derived from an estimated 6,000 genes. Comparison of these cDNA sequences with protein databases indicates that 46% contain their start codon. Further annotation included Gene Ontology functional classification, InterPro domain analysis, alternative splicing and non-coding RNA identification. Gene expression profiles were derived from EST counts and used to define transcripts specific to metamorphic stages of development. Moreover, these ESTs allowed identification of a set of 225 polymorphic microsatellites that can be used as genetic markers. Conclusion These cDNA sequences permit in silico cloning of numerous genes and will facilitate studies aimed at deciphering the roles of cognate genes expressed in the nervous system during neural development and metamorphosis. The genomic resources developed to study X. tropicalis biology will accelerate exploration of amphibian physiology and genetics. In particular, the model will facilitate analysis of key questions related to anuran embryogenesis and metamorphosis and its associated regulatory processes.

Manual cultivar identification diagram is a new strategy for plant cultivar identification based on DNA markers, providing information to efficiently separate cultivars. We tested 25 pairs of apple EST-SSR primers for amplification of PCR products from loquat cultivars. These EST-SSR primers provided clear amplification products from the loquat cultivars, with a relatively high transferability rate of 84% to loquat; 11 pairs of primers amplified polymorphic products. After analysis of 24 red-fleshed loquat accessions, we found that only 7 pairs of primers could clearly separate all of them. A cultivar identification diagram of the 24 cultivars was constructed using polymorphic bands from the DNA fingerprints and EST-SSR primers. Any two of the 24 cultivars could be rapidly separated from each other, according to the polymorphic bands from the cultivars; the corresponding primers were marked in the correct position on the cultivar identification diagram. This red-flesh loquat cultivar identification diagram can separate the 24 red-flesh loquat cultivars, which is of benefit for loquat cultivar identification for germplasm management and breeding programs.

Full Text Available O artigo discute as dimensões do cuidado a partir da experiência das autoras na docência em obstetrícia. Apresentam-se as estratégias utilizadas na supervisão de estágio relativas a duas dimensões do cuidado humanizado: a relação profissional-usuário e a organização dos serviços em dois hospitais. Inicialmente, faz-se uma breve leitura sobre a humanização do cuidado e a configuração de um novo paradigma de atenção à saúde. A seguir, problematiza-se a incorporação dessa dimensão nos processos de ensino-aprendizagem a partir de duas situações-problema vivenciadas durante os estágios. Observou-se que alguns profissionais dos hospitais onde os estágios são realizados incorporam as práticas desenvolvidas, e, gradativamente, a organização do serviço e as relações de cuidado em saúde vão se transformando.

El entorno cotidiano, la estética kitsch y su relación con los diseños

Full Text Available Algunos productos del diseño gráfico parecen reflejar directamente el entorno cotidiano de los seres humanos. El hogar es el primer lugar que se modifica de acuerdo con la percepción estética de sus habitantes. La estética kitsch está presente en la decoración de los hogares, pues es la que requiere menor esfuerzo tanto para aprenderse, como para realizarse. Los investigadores encontramos que usualmente hay cinco grupos de objetos en los hogares de las personas: religiosos, místicos, evocativos, naturales y utilitarios. Al analizar la organización de estos objetos aparece un orden, un acomodo reticular, una concordancia de color y una saturación. Por otro lado las portadas de las revistas de espectáculos en México presentan composiciones similares a las encontradas en las casas visitadas, tanto en el agrupamiento de objetos, como en la variedad y en la heterogénea calidad de las imágenes presentadas.

According to arrangement between the State Office for Nuclear Safety (SUJB) and the Federal Ministry of Agriculture and Forestry, Environment and Water Management, Radiation Protection Division (BMLFUW) there is prepared and regularly tested emergency data exchange between the ESTE systems at the SUJB and at the BMLFUW. The ESTE system is support instrument for off-site emergency response and its main goals in case of severe reactor accidents are: .detection of the way of the release from the reactor core to the environment .detection of the state of the reactor core, .prediction of the source term, .estimation of really observed release rate to the atmosphere, .calculations of radioactive clouds dispersion and radiological impacts assessments. The este systems are implemented at the Emergency Response Centre of the Czech Republic (SUJB) in Prague and Austrian versions are implemented at the Crisis Centre of the Austrian Republic (BMLFUW) in Vienna. The main objective of data exchange according to the above mentioned agreement is to extend bilateral information exchange and make a step in the direction of harmonizing emergency management in case of radiological accidents. Automatic data exchange between the este systems at the SUJB Prague and at the BMLFUW Vienna is performed for testing and training regularly once a month. This assists us to have the system ready in any time. (authors)

Full Text Available Resumo: O objetivo deste artigo é apreender a racionalidade tecnológica no contexto da Universidade Tecnológica Federal do Paraná. Única no país com esta denominação, ela tem a maioria dos seus cursos voltados para a formação de engenheiros no Brasil. No âmbito dessa formação, incluímos o estudo da estética, como discussão alternativa, por entendê-la significativa na formação social do sujeito enquanto dimensão emancipatória gerada no movimento de criação e de inovação tecnológica e que hoje é deixada em segundo plano nesse contexto. Este artigo constituiu-se a partir da revisão das ideias de Marcuse, Adorno, Habermas e Horkheimer, Rancière, os quais abordam a presente temática sob a perspetiva da autonomia do sujeito em oposição às interpretações normativas e tecnocráticas da sociedade.

The co-existence of several ploidy types in natural populations makes the cyprinid loach Misgurnus anguillicaudatus an exciting model system to study the genetic and phenotypic consequences of ploidy variations. A first step in such effort is to identify the specific ploidy of an individual. Currently popular methods of karyotyping via cytological preparation or flow cytometry require a large amount of tissue (such as blood) samples, which can be damaging or fatal to the fishes. Here, we developed novel microsatellite markers (SSR markers) from M. anguillicaudatus and show that they can effectively discriminate ploidy using samples collected in a minimally invasive way. Specifically, we generated whole genome transcriptomes from multiple M. anguillicaudatus using the Illumina paired-end sequencing. Approximately 150 million raw reads were assembled into 76,544 non-redundant unigenes. A total of 8,194 potential SSR markers were identified. We selected 98 pairs with more than five tandem repeats for further assays. Out of 45 putative EST-SSR markers that successfully amplified and harbored polymorphism in diploids, 11 markers displayed high variability in tetraploids. We further demonstrate that a set of five EST-SSR markers selected from these are sufficient to distinguish ploidy levels, by first validating them on 69 reference specimens with known ploidy levels and then subsequently using fresh-collected 96 ploidy-unknown specimens. The results from EST-SSR markers are highly concordant with those from independent flow cytometry analysis. The novel EST-SSR markers developed here should facilitate genetic studies of polyploidy in the emerging model system M. anguillicaudatus.
