An Approach to Textual Steganography  

NASA Astrophysics Data System (ADS)

Textual steganography is a means of concealing an encoded message within text. The appeal in such a system is its potential for hiding the fact that encoding is taking place. The failure to hide the presence of encoding is a form of information leakage and an inherent risk since it suggests that there is important or valuable information in transit. This is considered a major limitation of existing cryptographic techniques as applied to secure information transfer. In this paper, we describe an experimental system that we have developed as a test bed for textual steganography. This system allows us to explore the application of part of speech tagging, word sense disambiguation and synonym replacement as component strategies for textual steganography.

Universal lossless compression algorithm for textual images  

NASA Astrophysics Data System (ADS)

In recent years, an unparalleled volume of textual information has been transported over the Internet via email, chatting, blogging, tweeting, digital libraries, and information retrieval systems. As the volume of text data has now exceeded 40% of the total volume of traffic on the Internet, compressing textual data becomes imperative. Many sophisticated algorithms were introduced and employed for this purpose including Huffman encoding, arithmetic encoding, the Ziv-Lempel family, Dynamic Markov Compression, and Burrow-Wheeler Transform. My research presents novel universal algorithm for compressing textual images. The algorithm comprises two parts: 1. a universal fixed-to-variable codebook; and 2. our row and column elimination coding scheme. Simulation results on a large number of Arabic, Persian, and Hebrew textual images show that this algorithm has a compression ratio of nearly 87%, which exceeds published results including JBIG2.

A Computational Approach to Qualitative Analysis in Large Textual Datasets  

PubMed Central

In this paper I introduce computational techniques to extend qualitative analysis into the study of large textual datasets. I demonstrate these techniques by using probabilistic topic modeling to analyze a broad sample of 14,952 documents published in major American newspapers from 1980 through 2012. I show how computational data mining techniques can identify and evaluate the significance of qualitatively distinct subjects of discussion across a wide range of public discourse. I also show how examining large textual datasets with computational methods can overcome methodological limitations of conventional qualitative methods, such as how to measure the impact of particular cases on broader discourse, how to validate substantive inferences from small samples of textual data, and how to determine if identified cases are part of a consistent temporal pattern.

Relevance, textual unity, and politeness in writing about science  

SciTech Connect

The question of whether there are social implications of linguistic choices in unifying a text is investigated empirically by this study which accounts for the interpretation of implicatures in conversation and written texts. It considers Relevance Theory (Sperber and Wilson 1988, Blakemore 1987, Blass 1990) to be the explanation of the unity of the text, as opposed to semantic theories of cohesion (Halliday and Hasan 1976) or pragmatic theories of coherence (van Dijk 1977). This study presents a model of three types of textual unifiers: overt (referring specifically to the text), embedded (referring to intra- and extra-textual information), and inference (not referring to the text at all). It hypothesizes that different genres are characterized by the predominance of different types of textual unifiers, and that readers will prefer those texts that rely on inferential unifiers which emphasize the reader's ability to participate in creating the meaning of the text. Eighteen texts of 275 words each are selected from three genres: scientific magazines, introductory science textbooks, and essays on science. The texts are found to vary significantly by genre in the type of textual unifier used. An Overtness Index expresses the ratio of the marked forms: science textbooks have more Overt unifiers (such as connective phrases) and thus a high Overtness Index; essays rely more on Inference unifiers (not represented by words) and thus have a low Overtness Index. The texts are submitted to 188 readers, and a significantly high number of all types of readers prefer the texts with the lower Overtness Indices-the essays. Thus a low Overtness Index is one feature of texts preferred by readers, supporting the hypotheses that genres of texts vary in the type of unifier used and that readers prefer texts that allow them to participate in constructing the meaning of the text.

Textual Standardization and the DSM-5 "Common Language".  


In February 2010, the American Psychiatric Association (APA) launched their DSM-5 website with details about the development of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The APA invited "the general public" to review the draft diagnostic criteria and provide written comments and suggestions. This revision marks the first time the APA has solicited public review of their diagnostic manual. This article analyzes reported speech on the DSM-5 draft diagnostic criteria for the classification Posttraumatic Stress Disorder. It demonstrates how textual standardization facilitates the cultural portability of the DSM-5 diagnostic criteria such that a community of speakers beyond the borders of the APA come to be seen as exemplary speakers, writers, and revisers of the professional style. Furthermore, analysis shows how co-authoring practices recontextualize the "voice" and persona of putative patient reported speech on Criterion D2. As a consequence of textual standardization, spoken discourse becomes recontextualized as the product of scientific inquiry and the organization of psychiatric knowledge. PMID:24682628

Fusion of Laboratory and Textual Data for Investigative Bioforensics  

SciTech Connect

Chemical and biological forensic programs focus on the identification of a threat and acquisition of laboratory measurements to determine how a threat agent may have been produced. However, to generate investigative leads, it might also be useful to identify institutions where the same agent has been produced by the same or a very similar process, since the producer of the agent may have learned methods at a university or similar institution. We have developed a Bayesian network framework that fuses hard and soft data sources to assign probability to production practices. It combines the results of laboratory measurements with an automatic text reader to scan scientific literature and rank institutions that had published papers on the agent of interest in order of the probability that the institution has the capability to generate the sample of interest based on laboratory data. We demonstrate the Bayesian network on an example case from microbial forensics, predicting the methods used to produce Bacillus anthracis spores based on mass spectrometric measurements and identifying institutions that have a history of growing Bacillus spores using the same or highly similar methods. We illustrate that the network model can assign a higher posterior probability than expected by random chance to appropriate institutions when trained using only a small set of manually analyzed documents. This is the first example of an automated methodology to integrate experimental and textual data for the purpose of investigative forensics.

Gross's anatomy: textual politics in science/biology education research  

NASA Astrophysics Data System (ADS)

In approaching how the grotesque is—or should be—situated within contemporary science (biology) education practices, Weinstein and Broda undertake a passionate reclaim of an education that is at the same time scientific, critical, and liberatory. However legitimate, their work offers more than they probably could have anticipated: It exemplifies how the textual structure of a research article can be such as to "tip-off" readers about how it is supposed to be understood. In this way, what one learns from reading the manuscript is grounded on the way the authors examine the data presented. That is, the findings are not intrinsic to the materials collected, but constructed within the analyses that precede/follow the account of each one of the four "specimens" reported. Therefore, the present commentary seeks to re-consider the original study from an alternative perspective, one that challenges its seemingly objective (re)construction of facts by placing emphasis on how the text contains instructions for its own interpretation and validation. Ultimately, the purpose here is to describe and discuss the interpretive and validation work that is done by this discursive mechanism of self-appraisal rather than discredit the two authors' initiative.

Textrous!: Extracting Semantic Textual Meaning from Gene Sets  

PubMed Central

The un-biased and reproducible interpretation of high-content gene sets from large-scale genomic experiments is crucial to the understanding of biological themes, validation of experimental data, and the eventual development of plans for future experimentation. To derive biomedically-relevant information from simple gene lists, a mathematical association to scientific language and meaningful words or sentences is crucial. Unfortunately, existing software for deriving meaningful and easily-appreciable scientific textual ‘tokens’ from large gene sets either rely on controlled vocabularies (Medical Subject Headings, Gene Ontology, BioCarta) or employ Boolean text searching and co-occurrence models that are incapable of detecting indirect links in the literature. As an improvement to existing web-based informatic tools, we have developed Textrous!, a web-based framework for the extraction of biomedical semantic meaning from a given input gene set of arbitrary length. Textrous! employs natural language processing techniques, including latent semantic indexing (LSI), sentence splitting, word tokenization, parts-of-speech tagging, and noun-phrase chunking, to mine MEDLINE abstracts, PubMed Central articles, articles from the Online Mendelian Inheritance in Man (OMIM), and Mammalian Phenotype annotation obtained from Jackson Laboratories. Textrous! has the ability to generate meaningful output data with even very small input datasets, using two different text extraction methodologies (collective and individual) for the selecting, ranking, clustering, and visualization of English words obtained from the user data. Textrous!, therefore, is able to facilitate the output of quantitatively significant and easily appreciable semantic words and phrases linked to both individual gene and batch genomic data.

Textual query of personal photos facilitated by large-scale web data.  


The rapid popularization of digital cameras and mobile phone cameras has led to an explosive growth of personal photo collections by consumers. In this paper, we present a real-time textual query-based personal photo retrieval system by leveraging millions of Web images and their associated rich textual descriptions (captions, categories, etc.). After a user provides a textual query (e.g., “water”), our system exploits the inverted file to automatically find the positive Web images that are related to the textual query “water” as well as the negative Web images that are irrelevant to the textual query. Based on these automatically retrieved relevant and irrelevant Web images, we employ three simple but effective classification methods, k-Nearest Neighbor (kNN), decision stumps, and linear SVM, to rank personal photos. To further improve the photo retrieval performance, we propose two relevance feedback methods via cross-domain learning, which effectively utilize both the Web images and personal images. In particular, our proposed crossdomain learning methods can learn robust classifiers with only a very limited amount of labeled personal photos from the user by leveraging the prelearned linear SVM classifiers in real time. We further propose an incremental cross-domain learning method in order to significantly accelerate the relevance feedback process on large consumer photo databases. Extensive experiments on two consumer photo data sets demonstrate the effectiveness and efficiency of our system, which is also inherently not limited by any predefined lexicon. PMID:20714015

A Dynamic Ensemble Framework for Mining Textual Streams with Class Imbalance  

PubMed Central

Textual stream classification has become a realistic and challenging issue since large-scale, high-dimensional, and non-stationary streams with class imbalance have been widely used in various real-life applications. According to the characters of textual streams, it is technically difficult to deal with the classification of textual stream, especially in imbalanced environment. In this paper, we propose a new ensemble framework, clustering forest, for learning from the textual imbalanced stream with concept drift (CFIM). The CFIM is based on ensemble learning by integrating a set of clustering trees (CTs). An adaptive selection method, which flexibly chooses the useful CTs by the property of the stream, is presented in CFIM. In particular, to deal with the problem of class imbalance, we collect and reuse both rare-class instances and misclassified instances from the historical chunks. Compared to most existing approaches, it is worth pointing out that our approach assumes that both majority class and rareclass may suffer from concept drift. Thus the distribution of resampled instances is similar to the current concept. The effectiveness of CFIM is examined in five real-world textual streams under an imbalanced nonstationary environment. Experimental results demonstrate that CFIM achieves better performance than four state-of-the-art ensemble models.

Teaching Intraverbal Behavior to Children with Autism: A Comparison of Textual and Echoic Prompts  

PubMed Central

Although echoic prompts may be effective for teaching intraverbal behavior to children with autism, the performance of some children may become dependent on such prompts (i.e., the prompts cannot be eliminated). Recent research suggests that visual rather than echoic prompts may be used to teach children with autism a variety of skills and may facilitate independent performance. In the present study, an adapted alternating treatments design was used to compare the effects of using visual (textual) and echoic prompts on acquisition of intraverbal responses (answering questions) by 2 children with autism. The results indicated that the textual prompts were more effective than the echoic prompts. Implications for the use of visual prompts during instruction with children with autism are discussed.

Textual alchemy: the transformation of pseudo-Albertus Magnus's Semita recta into the Mirror of Lights.  


This article explores the strategies of and the reasons behind the reworking of pseudo-Albertus Magnus's Semita recta into the Mirror of Lights. I argue that the redactor sought to provide a more comprehensive defence of the legitimacy of alchemy than found in the Semita recta. In the process of doing so, he reshaped the original text so as to present three units that addressed different parts of the alchemical opus: first, theory and justification of alchemy; second, basic information on substances and procedures; and, third, practice. The redactor employed sophisticated textual tools identical to those seen in scholastic texts. These strategies, I argue, constitute part of the redactor's attempt to bring authority and credibility to his project and to alchemy in general. Certainly, much more attention needs to be paid to these experiments of textual alchemy in order to understand the practice of alchemy in the late medieval period. PMID:20506702

Using Semantic Web technology to support icd-11 textual definitions authoring.  


The beta phase of the 11th revision of International Classification of Diseases (ICD-11) intends to accept public input through a distributed model of authoring. One of the core use cases is to create textual definitions for the ICD categories. The objective of the present study is to design, develop, and evaluate approaches to support ICD-11 textual definitions authoring using Semantic Web technology. We investigated a number of heterogeneous resources related to the definitions of diseases, including the linked open data (LOD) from DBpedia, the textual definitions from the Unified Medical Language System (UMLS) and the formal definitions of the Systematized Nomenclature of Medicine-Clinical Terms (SNOMED CT). We integrated them in a Semantic Web framework (i.e., the Linked Data in a Resource Description Framework [RDF] triple store), which is being proposed as a backend in a prototype platform for collaborative authoring of ICD-11 beta. We performed a preliminary evaluation on the usefulness of our approaches and discussed the potential challenges from both technical and clinical perspectives. PMID:23601451

Comparing the quality of accessing medical literature using content-based visual and textual information retrieval  

NASA Astrophysics Data System (ADS)

Content-based visual information (or image) retrieval (CBIR) has been an extremely active research domain within medical imaging over the past ten years, with the goal of improving the management of visual medical information. Many technical solutions have been proposed, and application scenarios for image retrieval as well as image classification have been set up. However, in contrast to medical information retrieval using textual methods, visual retrieval has only rarely been applied in clinical practice. This is despite the large amount and variety of visual information produced in hospitals every day. This information overload imposes a significant burden upon clinicians, and CBIR technologies have the potential to help the situation. However, in order for CBIR to become an accepted clinical tool, it must demonstrate a higher level of technical maturity than it has to date. Since 2004, the ImageCLEF benchmark has included a task for the comparison of visual information retrieval algorithms for medical applications. In 2005, a task for medical image classification was introduced and both tasks have been run successfully for the past four years. These benchmarks allow an annual comparison of visual retrieval techniques based on the same data sets and the same query tasks, enabling the meaningful comparison of various retrieval techniques. The datasets used from 2004-2007 contained images and annotations from medical teaching files. In 2008, however, the dataset used was made up of 67,000 images (along with their associated figure captions and the full text of their corresponding articles) from two Radiological Society of North America (RSNA) scientific journals. This article describes the results of the medical image retrieval task of the ImageCLEF 2008 evaluation campaign. We compare the retrieval results of both visual and textual information retrieval systems from 15 research groups on the aforementioned data set. The results show clearly that, currently, visual retrieval alone does not achieve the performance necessary for real-world clinical applications. Most of the common visual retrieval techniques have a MAP (Mean Average Precision) of around 2-3%, which is much lower than that achieved using textual retrieval (MAP=29%). Advanced machine learning techniques, together with good training data, have been shown to improve the performance of visual retrieval systems in the past. Multimodal retrieval (basing retrieval on both visual and textual information) can achieve better results than purely visual, but only when carefully applied. In many cases, multimodal retrieval systems performed even worse than purely textual retrieval systems. On the other hand, some multimodal retrieval systems demonstrated significantly increased early precision, which has been shown to be a desirable behavior in real-world systems.

Integrating Ontological Knowledge and Textual Evidence in Estimating Gene and Gene Product Similarity  

SciTech Connect

With the rising influence of the Gene On-tology, new approaches have emerged where the similarity between genes or gene products is obtained by comparing Gene Ontology code annotations associ-ated with them. So far, these approaches have solely relied on the knowledge en-coded in the Gene Ontology and the gene annotations associated with the Gene On-tology database. The goal of this paper is to demonstrate that improvements to these approaches can be obtained by integrating textual evidence extracted from relevant biomedical literature.

Textual prompts as an antecedent cue self-management strategy for persons with mild disabilities.  


Providing learners written task analyses to be used as textual prompts was examined as a self-management strategy for persons with mild disabilities. Initially, modeling, corrective verbal feedback, and contingent descriptive praise were employed to train participants to use the written task analysis to perform one home maintenance task. Subsequently, participants were tested on their use of different task analyses combined with general feedback to perform two novel home maintenance tasks. No training was provided on how to use these new task analyses. Either a multiple baseline or a multiple probe across settings experimental design was used to control extraneous variables. Results indicated that the written task analyses served as self-administered textual prompts and, along with general feedback, provided stimulus control for the second and third tasks. When the self-management task analyses and general feedback were withdrawn, transfer of stimulus control occurred to the natural discriminative stimuli for the majority of tasks. The research suggests that written task analyses, as presented in the present study, may have utility for the self-management of instruction by persons with mild disabilities. PMID:8037645

VV 410, un sistema interactuante del tipo M 51  

NASA Astrophysics Data System (ADS)

We analize spectroscopic and photometric results for VV 410, an interacting system of galaxies of the M 51 type, whose components which have a separation of 78", are connected by a distorted long spiral arm. The main galaxy presents two marked regions (NW and SE regions) at the ends of the bar structure. It has been determined that there is starburst activity in the mentioned regions, being this activity enhanced at the SE region; the stellar formation activity is stronger in the satellite nucleus than in the main galaxy nucleus. Our results suggest that in the NW region would be an older population than the global one, being this older population more prevalent than in the SE region. Oxygen and Nitrogen abundances were derived, and starburst ages were estimated. Heliocentric radial velocities distributions were obtained for both galaxies, along their major axis, and masses were calculated. Photometric B V R I studies show that the NW and SE regions are quite blue, the same that the values found in the regions that belong to the external parts of the disc, near the SE region, while the nucleus of the main galaxy has redder colors (the extinction is high in this zone). The colors of the satellite are also quite blue.

A comparison of textual and echoic prompts on the acquisition of intraverbal behavior in a six-year-old boy with autism  

PubMed Central

A comparison of textual and echoic prompts was conducted to determine which form of prompts was more effective for teaching intraverbal behavior to a 6-year-old boy with autism. A multiple baseline design across three sets of questions measured (a) the number of full-sentence target answers, (b) partial answers that made sense, and (c) partial answers that did not make sense, or no response, to direct questions asked. A fading procedure using either scripted textual or scripted echoic prompts was employed to evoke the child's correct answers. Although both forms of prompts were effective, results indicated that textual prompts were much more effective. These findings suggest that textual prompts may be effective in teaching complex skills to children with autism. ImagesFig. 1

[Textual criticized and collated on names and breeds of Tibetan medicine "Dida"].  


Integrating textual criticism literatures with field survey, the name, classification and botanical originals of breeds of Tibetan medicine "Dida" were discussed in this paper. The results showed that it's very intricate and confusion in the names, breeds and botanical originals of "Dida", and those were the key restricting factors resulting in shortfall and difficult formulation in quality standard of "Dida". The similar situations are existing universally in ethnodrugs, and reflecting the necessity and urgency to collate ethnodrug breeds. On the other hand, Because of the morphologic description on the botanical origins of drug was often simple in the ancient literatures, and in most cases, the botanical origins of the drug were difficult to identify accurately on the basis of the literatures. So, in the collating the breeds, it's necessary to follow the principle of "according to the ancient literatures but no rigidly", and to pay attention to the historical vicissitude of the drug breeds and origins, and the survey of present resources and clinical using, draw actively on outcome of chemical and biological active researches. That inherited the characteristics and advantages of ethnodrugs, and promoted them them modernization. PMID:20222437

Aligning ontologies and integrating textual evidence for pathway analysis of microarray data  

SciTech Connect

Expression arrays are introducing a paradigmatic change in biology by shifting experimental approaches from single gene studies to genome-level analysis, monitoring the ex-pression levels of several thousands of genes in parallel. The massive amounts of data obtained from the microarray data needs to be integrated and interpreted to infer biological meaning within the context of information-rich pathways. In this paper, we present a methodology that integrates textual information with annotations from cross-referenced ontolo-gies to map genes to pathways in a semi-automated way. We illustrate this approach and compare it favorably to other tools by analyzing the gene expression changes underlying the biological phenomena related to stroke. Stroke is the third leading cause of death and a major disabler in the United States. Through years of study, researchers have amassed a significant knowledge base about stroke, and this knowledge, coupled with new technologies, is providing a wealth of new scientific opportunities. The potential for neu-roprotective stroke therapy is enormous. However, the roles of neurogenesis, angiogenesis, and other proliferative re-sponses in the recovery process following ischemia and the molecular mechanisms that lead to these processes still need to be uncovered. Improved annotation of genomic and pro-teomic data, including annotation of pathways in which genes and proteins are involved, is required to facilitate their interpretation and clinical application. While our approach is not aimed at replacing existing curated pathway databases, it reveals multiple hidden relationships that are not evident with the way these databases analyze functional groupings of genes from the Gene Ontology.

Ambienti Circumstellari ed Interstellari di Supernovae di vario Tipo ed Applicazioni Astrofisiche  

NASA Astrophysics Data System (ADS)

Nella presente tesi vengono studiati gli ambienti circumstellari ed interstellari di supernovae (anche SNe; singolare SN) di vario tipo. In particolare si descrivono alcune applicazioni astrofisiche, relative a questi ambienti, che permettono di desumere informazioni sui sistemi stellari progenitori delle supernovae o di determinare le distanze a tali oggetti. L' emissione radio da supernovae, prodotta nell' ambiente circumstellare ad opera dell'interazione idrodinamica del gas di SN con l' ambiente circostante, puo' essere impiegata come mezzo di indagine del sistema di pre-supernova. In particolare si e' introdotta l'idea che tale emissione possa essere impiegata nel caso delle SNe di tipo Ia come test dei sistemi progenitori di tipo simbiotico. Il test e' stato effettuato sulla SN 1986G, per la quale avevamo ottenuto limiti superiori a lunghezze d'onda radio. Nel caso che un sistema simbiotico sia responsabile di una SN Ia, l'interazione tra l' ejecta e una shell circumstellare origina, in un'epoca molto prossima al massimo di luce, un'emissione radio rivelabile con strumenti tipo Very Large Array. Inoltre l'emissione radio fornisce informazioni circa gli stadi di pre-supernova nel caso di altri tipi di supernova. In questo lavoro di tesi vengono presentati i risultati ottenuti nel caso delle SNe di tipo II 1984E e 1986E. Queste due SNe non mostrano emissione radio: la prima, in prossimita del massimo ottico, stava interagendo con una shell circumstellare prodotta da un episodio di perdita di massa di breve durata in fase di pre-supernova; la seconda, invece e' la prima SN ``vecchia'' ad essere rivelata nell' ottico ma non nel radio (l' oggetto non ha ancora iniziato la fase di supernova remnant ed emette radiazione ottica prodotta ancora per interazione circumstellare). In ambiente circum-interstellare, gli echi di luce, prodotti dallo scattering della luce della supernova ad opera della polvere presente, possono essere utilizzati per determinare le distanze extra-galattiche per via puramente geometrica (Sparks 1994; 1996). Osservazioni da terra, in imaging e polarimetria, sono state utilizzate per selezionare un numero promettente di candidati, che mostrano emissione visibile alla posizione della supernova. Tali candidati sono promettenti non solo per l' applicazione del metodo descritto ma anche per dedurre informazioni circa le supernovae medesime e le relative popolazioni stellari.

Combining Hierarchical and Associative Gene Ontology Relations with Textual Evidence in Estimating Gene and Gene Product Similarity  

SciTech Connect

Gene and gene product similarity is a fundamental diagnostic measure in analyzing biological data and constructing predictive models for functional genomics. With the rising influence of the Gene Ontology, two complementary approaches have emerged where the similarity between two genes or gene products is obtained by comparing Gene Ontology (GO) annotations associated with the genes or gene products. One approach captures GO-based similarity in terms of hierarchical relations within each gene subontology. The other approach identifies GO-based similarity in terms of associative relations across the three gene subontologies. We propose a novel methodology where the two approaches can be merged with ensuing benefits in coverage and accuracy, and demonstrate that further improvements can be obtained by integrating textual evidence extracted from relevant biomedical literature.

Textual entailment method for linking text of an abstract to text in the main body of a document  

US Patent & Trademark Office Database

A system and method are provided for processing an input document which enable assessment of the coherence of an abstract of the document. The method includes storing the document in memory and, for each sentence of the abstract, comparing the sentence with sentences of a main body of the document using textual entailment techniques to identify whether the sentence of the abstract entails a sentence in the main body of the document. Links can then be generated between the entailing sentences of the abstract and the corresponding entailed sentences of the document. The document and generated links are output. The links enable the coherence of the abstract to be evaluated, either manually or automatically, using an evaluation component of the system.

Teaching Generative Reading Via Recombination of Minimal Textual Units: A Legacy of Verbal Behavior to Children in Brazil  

PubMed Central

This paper reports results of two studies that sought to teach generative reading skills to a large group of Brazilian children who were exhibiting protracted failure in school. Inspired by Skinner’s analysis of verbal relations and minimal verbal units, the methodology took advantage of certain characteristics of Portuguese. Many words in this language are comprised of two-letter syllabic units (e.g., BO+LA= ball, CA+BO= handle, LA+TA= can) that can be recombined to form new words (e.g., BOCA= mouth, BOTA= boot), thus establishing a route to generative reading via recombinative generalization. Such syllabic units were incorporated within curricular framework that used matching-to-sample and learning by exclusion methods to teach matching relations involving pictures, printed and spoken words, and printed and spoken syllables. Study 1 was conducted within a university-based learning center that maintained certain aspects of laboratory conditions. It showed that teaching textual relations between dictated and printed syllables could control procedurally the inter- and intra-participant variability observed in past studies that lacked this feature -resulting in virtually universally positive teaching outcomes. Study 2 was conducted in a public school programs that applied the same basic training methodology. Positive training outcomes in an experimental group were approximately 3–5 times greater than that in a placebo control group. Together, these studies illustrate that the functional analysis in Verbal Behavior is having a direct impact in educational science in Brazil. It has led to procedures that can be effectively translated from the laboratory to the community via delivery systems that can be implemented in the developing world.

[The decipher, annotation and textual researches of 7 anti-dysentery prescriptions in the Tangut medical documents unearthed in Khara-Khoto].  


There were 7 anti-dysentery prescriptions in the Tangut medical documents unearthed in Khara-Khoto, preserved in Russia, which were deciphered, annotated and textually researched based on the Tangut tool books like Wenhai (Word Ocean), Tongyin (Homophones), and Fan han he shi zhang zhong zhu (A Tangut-Chinese Timely Gem Dictionary), combining with classical medical documents and application of knowledge of ancient Chinese language. It can be sure that these prescriptions came from the central plains of China during the Song Dynasty, which were made use of by the prescriptions as they were by the physicians of the Western Xia regime, either made modifications and adjustments or without any change. For example, local foods like local sugar and cheese were added. As for the administration and dosage, again, they were applied by following the original one or changing a little according to the local diet customs. PMID:24060025

Composição química, evolução e cinemática de estrelas de tipo solar  

NASA Astrophysics Data System (ADS)

A composição química das estrelas de tipo solar é um diagnóstico extremamente valioso da evolução química do disco da Galáxia. Existe alguma evidência de que tal evolução tem sido heterogênea no espaço e ao longo do tempo e que a composição química do Sol pode não ser um padrão representativo de abundâncias. Neste trabalho, foram obtidas as abundâncias dos elementos químicos C, N, Na, Mg, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Zr, Ba, La, Ce, Nd e Sm em uma amostra de estrelas de tipo solar na vizinhança solar (distâncias £ 25 pc). A técnica empregada foi a análise espectroscópica diferencial em relação ao Sol, baseando-se em dados de alta resolução (R ~ 46.000) e alta razão sinal/ruído (S/R > 300), obtidos com o espectrógrafo échelle de bancada do telescópio de 1,5 m do CTIO. Adicionalmente, abundâncias de C e N foram obtidas através de síntese de bandas moleculares dos Sistemas Eletrônicos Swan do C2 e Vermelho do CN utilizando-se um programa de síntese espectral. Os parâmetros atmosféricos foram estabelecidos usando cores fotométricas, o equilíbrio de excitação e ionização de linhas do Fe e a análise da temperatura e da luminosidade estelares no diagrama HR. Os resultados de abundâncias químicas obtidos proporcionam uma melhor compreensão da relação das abundâncias conhecidas para o Sol com a das estrelas anãs de tipo G da população local, uma vez que as razões de abundâncias de diversos elementos (em relação ao ferro) obtidas para estrelas de metalicidade semelhante à solar diferem daquelas obtidas para o Sol. Tais resultados também contribuem para um melhor entendimento do processo de evolução química da vizinhança solar e do enriquecimento nucleossintético do disco galáctico.

riassunto. Introduzione. L'obiettivo principale del presente studio caso-controllo è stato quello di valutare le relazioni intercorrenti tra la psicopatologia dei disturbi del comportamento alimentare (DCA) con il differente orientamento religioso: intrinseco ed estrinseco. Metodi. Sono stati confrontati un gruppo di pazienti affetti da DCA (23 con anoressia nervosa, 10 con bulimia nervosa e 39 con disturbo d'alimentazione incontrollata) con un gruppo di controllo di soggetti sani, utilizzando la Religious Orientation Scale (ROS). Risultati. I pazienti affetti da DCA hanno mostrato punteggi più alti nella sottoscala della religiosità estrinseca e minori punteggi nella sottoscala riguardante la religiosità intrinseca rispetto ai controlli sani. Nessuna differenza significativa è stata osservata tra i gruppi di DCA in termini di punteggi ROS. Conclusioni. Punteggi più elevati riscontrati in pazienti con orientamento religioso estrinseco sembrano essere associati con la presenza di DCA, mentre un orientamento religioso di tipo intrinseco sembra rappresentare un fattore protettivo.

Comportamiento del Helio en estrellas químicamente peculiares  

NASA Astrophysics Data System (ADS)

Las estrellas químicamente peculiares (CP) se caracterizan por tener deficiencias y sobreabundancias de algunos elementos químicos de hasta 106 veces la abundancia solar. Además presentan variaciones en las líneas espectrales. Se piensa que ello se debe a que los campos magnéticos presentes en este tipo de estrellas son principalmente dipolares, con un eje de simetría diferente del eje de rotación. La distribución de los elementos sobreabundantes y deficientes no es homogénea sobre la superficie estelar y las variaciones observadas serían una consecuencia directa de la rotación estelar. Entre los elementos con abundancia anómala se encuentra el Helio, cuyas líneas tienen intensidades que no son consistentes con una abundancia normal, que no puede ser determinada del modo usual, o sea, considerando una atmósfera con composición solar. Con el fin de determinar la abundancia de este elemento, se inició un estudio de estrellas anómalas de Helio, Hew y He strong. Además se determinarán las abundancias de otros elementos anómalos como ser el Si, Cr, Mg, Mn y Fe. Las mismas se determinan del modo tradicional, o sea: a) medida de los anchos equivalentes de las líneas de los distintos elementos analizados; b) adopción de la temperatura efectiva, gravedad y abundancia del Helio; c) cálculo del modelo de atmósfera d) comparación con las observaciones y reinicio de un proceso iterativo hasta lograr un acuerdo entre todos los parámetros analizados. Las observaciones se llevaron a cabo en el Complejo Astronómico El Leoncito. Se observaron setenta y ocho estrellas anómalas de Helio. En este momento se está procediendo a calcular las abundancias correspondientes a los distintos elementos químicos. Para ello se hace uso de los modelos de Kurucz, ATLAS9. Los cálculos NLTE de las líneas de Helio se llevan a cabo con el programa MULTI y se compararán con los realizados con el programa WIDTH9 de Kurucz (LTE), con el objeto de resaltar la importancia de los efectos NLTE.

Investigação dos perfís temporais de alta resolução de explosões solares tipo-III decimétricas  

NASA Astrophysics Data System (ADS)

Explosões solares tipo-III indicam a presença de feixes de elétrons acelerados durante "flares" solares. Sua investigação fornece informações tanto sobre os processos de aceleração de partículas quanto das características do agente causador e do local de aceleração. Explosões tipo-III decimétricas são geradas por feixes de elétrons viajando através de arcos magnéticos densos da baixa coroa solar. Os perfís temporais destes fenômenos, quando tomados com alta resolução, informam sobre os mecanismos de aceleração de partículas do feixe e o meio de transporte da energia liberada a partir da região de aceleração. Usando o Brazilian Solar Spectroscope (BSS), em operação no INPE, foram registradas dezenas de explosões tipo-III decimétricas, dentro da faixa de 2050-2250 MHz com alta resolução temporal (20 ms), em 13 de setembro de 2001, entre 13:00 e 16:10 UT. Foram selecionadas 10 explosões isoladas para uma investigação estatística detalhada de seus perfís temporais, em todos os cerca de 50 canais de freqüência. Os resultados indicam que cerca de 70% dos perfís temporais são complexos tanto durante a subida quanto descida. Os 30% restantes indicam que os perfís da subida podem ser bem representados, na maioria dos casos, por um processo não-linear e uma parcela significativa por processos lineares. Os perfís temporais da descida são dominados por um decaimento não-linear. Neste trabalho, será efetuada uma análise dos perfís temporais, tanto durante a subida quanto descida do fluxo, para as explosões selecionadas, em termos dos prováveis mecanismos de aceleração e relaxamento. 2

Nossa motivação para tal estudo, uma busca de caudas em raios-X duros em fontes do tipo Z, foi o pouco conhecimento sobre a emissão nesta faixa de energia das referidas fontes quando comparadas, por exemplo, as fontes do tipo atoll (também BXBM). Apresentam-se a análise/redução de dados e explicita-se a maneira como o HEXTE mede o ru1do de fundo. Especial atenção é direcionada a este item devido a localização das fontes do tipo Z e também ao problema de contaminação por fontes próximas. Com exceção de ScoX-1, nenhuma cauda em raios-X duros foi encontrada para as outras fontes, a despeito de resultados de detecção dessas caudas em algumas fontes pelo satélite BeppoSAX. As interpretações deste resultado serão apresentadas. Do ponto de vista deste estudo, nós deduzimos que a produção de caudas de raios-X duros em fontes do tipo Z é um processo disparado quando, pelo menos, uma condição é satisfeita: o brilho da componente térmica do espectro precisa estar acima de um certo valor limiar de ~4´1036ergs-1.

Nevado del Huila, Columbia  

NASA Technical Reports Server (NTRS)

Nevado del Huila Volcano in Colombia is actually a volcanic chain running north to south, capped by a glacier. With peaks ranging in height from 2,600 to 5,780 meters (8,530 to 18,960 feet), Nevado del Huila is a stratovolcano composed of alternating layers of hardened lava, solidified ash, and volcanic rocks. Its first recorded eruption occurred in the mid-sixteenth century. The long-dormant volcano erupted again in mid-April 2007. A few months before the eruption, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite captured this image of Nevado del Huila, on February 23, 2007. In this image, the bright white area just east of the central summit is ice. Immediately west of the summit are bare rocks, appearing as blue-gray. West of those rocks, white reappears, but this patch of white results from clouds hovering in the nearby valley. In the east, the colors turn to brown (indicating bare rock) and bright green (indicating vegetation). ASTER photographed Nevado del Huila near the end of a long phase of quietude. On April 17, 2007, local authorities recorded seismic activity associated with rock fracturing on the volcano's central summit, according to the ReliefWeb Website. Activity intensified the following day with an eruption and mudflows, forcing thousands of nearby residents to evacuate. As the Associated Press reported, the eruption caused avalanches and floods that wiped away both houses and bridges. It marked the volcano's first recorded eruption since the Spanish colonized the area five centuries earlier.

["Legal highs": paradisi sicuri e legali? Uno studio sulla diffusione, conoscenza e consapevolezza del rischio delle nuove droghe psicoattive tra gli studenti del Regno Unito].  


RIASSUNTO. Introduzione. La recente comparsa delle nuove sostanze ricreazionali, combinata alla possibilità offerta da Internet di diffondere le informazioni velocemente, ha sollevato numerose nuove preoccupazioni nel campo legislativo, nel campo della ricerca sulle nuove sostanze e per quanto riguarda la salute pubblica. Metodi. È stato utilizzato un questionario semistrutturato pubblicizzato sul sito di Study Room da novembre a dicembre 2010 per esplorare la consapevolezza, l'uso e la percezione di rischio delle "legal highs" tra la popolazione studentesca nel Regno Unito. Risultati. Un terzo (31,40%) dei 446 partecipanti ha riferito l'uso di queste sostanze. Gli intervistati hanno riferito soprattutto l'uso di: mefedrone (41,4%), Salvia divinorum (20%), "spice drugs" (10,7%), metilone (1,4%), nafirone (NRG) (2,1%) e benzilpiperazina (BZP) (2,1%), mentre il 15,7% non sapeva che tipo di composto avesse assunto. La maggioranza (78,9%) considerava queste sostanze "legali", mentre il 74,2% non le considerava più sicure di composti illegali. Metà del campione (50,8%) era consapevole della presenza di componenti illegali nei prodotti consumati. Conclusioni. Lo studio contribuisce al tentativo di stimare l'uso e la consapevolezza del rischio in merito alle nuove sostanze psicoattive tra gli studenti del Regno Unito. Si ritengono necessari ulteriori studi, soprattutto in termini di personalità e stili di vita, al fine di inquadrare meglio queste nuove forme di abuso, anche in setting non propriamente ricreazionali.

Alberto del Pozo  

NSDL National Science Digital Library

The Cuban Heritage Collection of the University of Miami Libraries was a recipient of 17 original illustrations by Alberto del Pozo in 1998 from the Campilli family. "The Oricha Collection" is their gift, and it contains illustrations in pen, crayon, and ink and the collection "pays homage to the primary gods and goddesses that comprise the Afro-Cuban religion of Santer'a." The "Introduction" near the top of the page, is a good place for visitors to start learning about Pozo, who was a Parson's School of Design-trained, Cuban artist who died at the age of 47. The "Biographical Sketch" is worth looking at as well. Examples of his colorful, heavily patterned and symbolism-intensive drawings of Santeria gods and goddesses can be found in the link "Gallery". The description of each drawing is given in English and Spanish. Finally, visitors interested in more information on the Santeria, can look at the "Further Readings" link for authoritative books on the subject.

El McVCO es un generador de frecuencias basado en un microcontrolador que reemplaza al oscilador controlado por voltaje (VCO) utilizado en telemetría analógica de datos sísmicas. Acepta señales de baja potencia desde un sismómetro y produce una señal subportadora modulada en frecuencia adecuada para enlaces telefónicos o vía radio a un lugar remoto de recolección de datos. La frecuencia de la subportadora y la ganancia pueden ser seleccionadas mediante un interruptor. Tiene la opción de poder operar con dos canales para la observación con ganancia alta y baja. El McVCO fue diseñado con el propósito de mejorar la telemetría analógica de las señales dentro de la Pacific Northwest Seismograph Network (PNSN) (Red Sismográfica del Noroeste del Pacífico). Su desarrollo recibió el respaldo del Programa de Geofísica de la Universidad de Washington y del "Volcano Hazards and Earthquake Hazards programs of the United States Geological Survey (USGS) (Programa de Investigaciones de Riesgos Volcánicos y Programa de Investigaciones de Riesgos Sísmicos de los EEUU). Cientos de instrumentos se han construido e instalado. Además de utilizarlo el PNSN, el McVCO es usado por el Observatorio Vulcanológico de Alaska para monitorear los volcanes aleutianos y por el USGS Volcano Disaster Assistance Program (Programa de Ayuda en las Catástrofes Volcánicas del USGS) para responder a crisis volcánicas en otros países.

Matching performance of vehicle icons in graphical and textual formats.  


The current research classified 82 vehicle icons into seven categories (image-related, concept-related, semi-abstract, arbitrary, abbreviation, word, and combined) for their matching accuracy, matching sequence, and matching time. These data can be compared and used as a framework for future icon development. Forty participants, all with a university degree, took part in this experiment. Half of the participants had intensive driving experience, while the other half never driven a car. The results indicated that on average, word icons had a significantly greater matching accuracy than the other icon formats; ranging from 4.7 to 20.8% difference. Regarding the matching sequence, participants matched image-related icons before other icon formats. Arbitrary and combined icons took significantly longer to match than other icon formats by 1.4-6.2 s. Based on the high matching accuracy (86.3%) and high ratings on subjective design features, word format can be used for functions describable using simple English for users with English reading ability. Confusion matrices showed that 63.2% of the misunderstandings were caused by similarity in format or function. PMID:24315463

Interpreting personalization in England's National Health Service: a textual analysis  

Microsoft Academic Search

Different versions of choice are at work in England's National Health Service. A hard version of choice associated with provider competition (and patient exit) appears to be giving way to a ‘softer’ concept of ‘personalization’, emphasizing choice and voice at the micro level, but also drawing on solidaristic themes. As personalization becomes increasingly central to health reform, it is important

A Template Engine for Parsing Objects from Textual Representations  

NASA Astrophysics Data System (ADS)

Template engines are widely used for separation of business and presentation logic. They are commonly used in web applications for clean rendering of HTML pages. Another area of usage is message formatting in distributed applications where they transform objects to appropriate representations. This paper explores the possibility of using templates for a reverse process--for creating objects starting from their representations. We present the prototype of engine that we have developed, and describe benefits and drawbacks of this approach.

Cockpit data link displays - An evaluation of textual formats  

NASA Technical Reports Server (NTRS)

Data link technologies are being investigated for air/ground information transfer for commercial aircraft operation. This study was designed to measure which of four alpha-numeric display formats for display of data link information would lead to the quickest and most accurate memory retrieval in a part-task simulation environment. Pilots viewed a clearance for 10-15 seconds and were subsequently queried about the content of that clearance. Speed and accuracy of responses were measured across three retention tasks. The three retention tasks included free recall of a particular clearance. recognition of a previous clearance, and the comparison of element values between a previously displayed and current clearance. Each format was tested with and without a distraction task. Subjective ratings of each format were also collected. The analyses revealed no significant differences for reaction time or accuracy among the four formats. Explanations for these results as well as alternative methodologies are discussed.

Extensión del Formalismo de Orbitales de Defecto Cuántico al tratamiento del efecto Stark (SQDO).  

NASA Astrophysics Data System (ADS)

El estudio experimental de las interacciones de átomos Rydberg altamente excitados con campos eléctricos ha experimentado un creciente interés durante las dos últimas décadas debido, en gran medida, al desarrollo de nuevas técnicas para crear y estudiar átomos Rydberg en el laboratorio. Acompañando a estas nuevas técnicas experimentales, es necesario el desarrollo de modelos teóricos que nos permitan contrastar sus medidas y conocer mejor los fundamentos de los mismos. Desde el punto de vista teórico el conocimiento del desdoblamiento de los niveles energéticos de un átomo en función de la magnitud del campo eléctrico aplicado (lo que se conoce como mapa Stark) es el mejor punto de partida para la descripción del sistema y un prerrequisito fundamental para el cálculo de distintas propiedades atómicas en presencia del campo eléctrico tales como intensidades de transición, umbrales de ionización de campo eléctrico, tiempos de vida, posición y anchura de cruces evitados, etc. En este trabajo presentamos la adaptación del método de orbitales de defecto cuántico [1,2,3] al tratamiento del efecto Stark (SQDO) [4] y su aplicación al cálculo de los desdoblamientos energéticos y fuerzas de oscilador de estados Rydberg en los átomos de Li, Na y K. El propósito de este estudio es, por un lado, desarrollar métodos fiables para la determinación de propiedades atómicas en presencia de campos eléctricos y, por otro, mostrar la fiabilidad de las funciones de onda QDO en la descripción del efecto Stark en sistemas atómicos.

Decoding F508del Misfolding in Cystic Fibrosis  

PubMed Central

The functional deficiency of the cystic fibrosis transmembrane conductance regulator (CFTR), a plasma membrane chloride channel, leads to the development of cystic fibrosis. The deletion of a phenylalanine at residue 508 (F508del) is the most common cause of CFTR misfolding leading to the disease. The F508del misfolding originates in the first nucleotide-binding domain (NBD1), which induces a global conformational change in CFTR through NBD1’s interactions with other domains. Such global misfolding produces a mutant chloride channel that is impaired in exocytic trafficking, peripheral stability, and channel gating. The nature and atomic details of F508del misfolding have been subject to extensive research during the past decade. Current data support a central role for NBD1 in F508del misfolding and rescue. Many cis-acting NBD1 second-site mutations rescue F508del misfolding in the context of full-length CFTR. While some of these mutations appear to specifically counteract the F508del-induced misfolding, others release certain inherent conformational constraints of the human wild-type CFTR. Several small-molecule correctors were recently found to act on key interdomain interfaces of F508del CFTR. Potential rational approaches have been proposed in an attempt to develop highly effective small molecule modulators that improve the cell surface functional expression of F508del CFTR.

Molecular basis of DEL phenotype in the Chinese population  

PubMed Central

Background Rh blood group system is the most complex and immunogenetic blood group system. Prevalent RHD alleles vary in different populations. We conducted the present study to examine the genotype of DEL individuals and to elucidate whether novel alleles exist in the Chinese population. Methods DEL phenotype was identified by a serologic adsorption-elution method. The nucleotide sequences of ten RHD exons and exon-intron boundary regions were evaluated by RHD gene-specific PCR-SSP and sequencing. Results Of 42306 samples from individual donors and patients, 165 samples were typed as D-negative. Among these D-negative samples, 41 DEL individuals were observed. Thirty-seven DELs were confirmed to have the RHD1227A allele. Two DELs seemed to have RHD-CE-D hybrid alleles, including one RHD-CE (4–7)-D and one RHD-CE (2–5)-D. Two novel RHD alleles were found among the rest of the DEL samples, including one RHD93T?>?A and one RHD838G?>?A. Conclusion In this study, about 24.85% (41/165) of the apparent D-negative Chinese individuals were DEL. RHD1227G?>?A is the most frequent allele in Chinese DEL phenotypes, accounting for 90.24% (37/41). The RHD-CE-D hybrid allele might be the second most frequent DEL allele in the Chinese population. Our study would contribute to the understanding of the molecular mechanism underlying D antigen expression of DEL individuals and provide useful information for designing suitable genotyping strategies in RhD-negative individuals in Asia.

The Revista Médica del Instituto Mexicano del Seguro Social was published for the first time 52 years ago, and it has walked its way from local to international distribution. This journal has 23 000 subscribers, it is included in Medline and it reached a 0.112 SCImago Journal Rank in 2012. Its website receives around 200 000 visits monthly and 45 % are foreign visits. In the future, the peer review system is going to be strengthened, and the journal is going to offer audio, video, and applications to reinforce interactive participation between authors, readers in order to reach modernity and draw young new attention.

Modelo semi-empírico de protuberancia solar a partir del diagnóstico de densidades  

NASA Astrophysics Data System (ADS)

A partir de la observación del espectro del quintuplete de C III alrededor de 1175 Å, se ha realizado el diagnóstico de la densidad y presión electrónica, basado en el cálculo del cociente de las intensidades observadas. Una vez establecida la densidad electrónica, y con el cálculo de las velocidades Doppler, hemos investigado el flujo de masa en la protuberancia en función de la temperatura. Estableciendo como hipótesis la conservación del número de partículas que ingresan y salen del cuerpo de la protuberancia, se investiga la variación del área de un tubo de flujo semi-empírico en función de la temperatura. A partir de dicho diagnóstico, se examina el comportamiento del radio del tubo magnético en función de la temperatura, los que dan cuenta de la abertura de las líneas de campo magnético que confinan el plasma y de la divergencia del campo magnético en diferentes alturas de la atmósfera solar.

Peat soil flows in Bahía del Buen Suceso, Tierra del Fuego (Argentina)  

NASA Astrophysics Data System (ADS)

On the southeastern edge of Tierra del Fuego, a mountainous area with a cold humid oceanic climate, peat soils cover not only flat areas but also steep hillslopes under an evergreen Nothofagus betuloides forest. Peat flows in the form of chutes are very frequent on these hillslopes. Some data were gathered on the field for 11 of these movements and from aerial photographs for 21 of them. The results suggest that peat soils become unstable when thickness exceeds a critical value which depends on the slope. This critical slope depends on the altitude and aspect regardless of soil thickness. A temporal analysis carried out by tree-ring counting demonstrated that the occurrence of these movements is not random though there are some periods of higher hazard, the probable triggering mechanisms being heavy snowfalls or earthquakes.

Análisis del espectro infrarrojo del polvo interestelar asociado con cúmulos globulares y de su evolución temporal  

NASA Astrophysics Data System (ADS)

El trabajo que se presenta investiga la dinámica de las partículas de polvo interestelar eyectadas por estrellas gigantes rojas en un cúmulo globular utilizando simulaciones numéricas de su interacción con el campo gravitatorio y con la radiación electromagnética de las estrellas. Se pretende con ello determinar la distribución espacial de ese material como una función del tiempo en un sistema similar a NGC 104 (47 Tuc). A partir de la distribución espacial resultante se obtuvo el espectro infrarrojo integrado el cual sugiere que el máximo contraste con la radiación estelar ocurre en longitudes de onda cercanas a 300 ?m y que decrece rápidamente hacia longitudes de onda menores, en las que suelen realizarse las observaciones.

Field measurements of del13C in ecosystem respiration  

NASA Astrophysics Data System (ADS)

Stable carbon isotope del13C-measurements are extensively used to study ecological and biogeochemical processes in ecosystems. Above terrestrial ecosystems, atmospheric del13C can vary largely due to photosynthetic fractionation. Photosynthetic processes prefer the uptake of the lighter isotope 12C (in CO2), thereby enriching the atmosphere in 13C and depleting the ecosystem carbon. At night, when ecosystem respiratory fluxes are dominant, 13C-depleted CO2 is respired and thereby depletes the atmospheric del13C-content. Different ecosystems and different parts of one ecosystem (type of plant, leaves, and roots) fractionate and respire with a different del13C-ratio signature. By determining the del13C-signature of ecosystem respiration in temporal and spatial scale, an analysis can be made of the composition of respiratory sources of the ecosystem. A field study at a dry cropland after harvest (province of Viterbo, Lazio, Italy) was performed in the summer of 2013. A FTIR (Fourier Transform Infrared Spectrometer) was set up to continuously measure CO2-, CH4-, N2O-, CO- and del13C-concentrations. The FTIR was connected to 2 different flux measurements systems: a Flux Gradient system (sampling every half hour at 1.3m and 4.2m) and 2 flux chambers (measured every hour), providing a continuous data set of the biosphere-atmosphere gas fluxes and of the gas concentrations at different heights. Keeling plot intercept values of respiratory CO2, measured by the Flux Gradient system at night, were determined to be between -25‰ and -20‰. Keeling plot intercept values of respiratory CO2, measured by the flux chamber system, varied between -24‰ and -29‰, and showed a clear diurnal pattern, suggesting different (dominant) respiratory processes between day and night.

Molecular and cytogenetic characterization of del(9p) syndrome  

SciTech Connect

The del(9p) syndrome is characterized by mental retardation, trigonocephaly, midface hypoplasia, upward slanting palpebral fissures, a long philtrum, and is typically associated with a breakpoint at 9p22. Seventeen unrelated patients with del(9p) and their parents were analyzed by high resolution chromosome studies, molecular analysis using a series of highly polymorphic dinucleotide repeat markers for 9p, and fluorescence in situ hybridization (FISH) to characterize precisely the extent of chromosome loss. Eleven patients were found to have an interstitial deletion with breakpoints assigned to 9p22.1 and 9p24.3 in most cases. Two patients had familial unbalanced translocations of maternal origin and four had de novo complex rearrangements identified by high resolution analysis and FISH utilizing chromosome libraries. PCR analysis of eleven families with eight minisatellite markers determined paternal origin of the deletion in six cases and maternal origin in five. This suggests that the molecular event resulting in the deletion is equally prevalent in both male and female gametogenesis and that genomic imprinting does not play a role in the pathogenesis of del(9p) syndrome. Increased precision in mapping these minisatellite markers was also possible through this work. This study demonstrates the existence of molecular heterogeneity as six patients with a cytological breakpoint at 9p22.1 revealed three different molecular breakpoints. These findings suggest that genotype-phenotype correlations in deletion syndromes such as this should be based on high-resolution molecular analysis of the deleted chromosome segment. Work is in progress to map a series of cosmid probes by FISH relative to chromosomal breakpoints in these patients. These combined studies should provide a better understanding of the mechanisms involved in the pathogenesis of del(9p) syndrome and may identify loci where genes responsible for one or more aspects of the del(9p) phenotype may reside.

Moléculas orgánicas obtenidas en simulaciones experimentales del medio interestelar.  

NASA Astrophysics Data System (ADS)

Las nubes moleculares son regiones de formación de estrellas, con temperaturas cinéticas entre 10-50 K y densidades de 103-106 átomos cm-3. Su materia está formada por gas y polvo interestelar. Estas partículas de polvo están cubiertas por una fina capa de hielo, de unos 0.01 ?m, que contiene H2O y a menudo CO, CO2, CH3OH y NH3. El hielo es presumiblemente irradiado por fotones ultravioleta y rayos cósmicos en las zonas poco profundas de las nubes moleculares y las regiones circunestelares. En un sistema de vacío, P ˜ 10-7 mbar, simulamos la deposición de hielo a partir de 10 K y la irradiación ultravioleta por medio de una lámpara de descarga de hidrógeno activada con microondas. La evolución del hielo se observa por medio de un espectrómetro infrarrojo. De este modo es posible determinar la composición del hielo observado en el medio interestelar y predecir la presencia de moléculas aún no detectadas en el espacio, que han sido producto del procesamiento del hielo en nuestros experimentos. También es posible calentar el sistema hasta temperatura ambiente para sublimar el hielo depositado. Cuando el hielo ha sido previamente irradiado, se observa un residuo compuesto por moléculas orgánicas complejas, algunas prebióticas, como varios ácidos carboxílicos, aminas, amidas, ésteres y en menor proporción moléculas heterocíclicas y aminoácidos. Algunas de estas moléculas podrían detectarse en estado gaseoso por medio de observaciones milimétricas y de radio. También podrían estar presentes en el polvo cometario, cuyo análisis químico está planeado por las misiones Stardust y Rosetta. Mientras tanto, nuestro grupo está llevando a cabo el análisis de partículas de polvo interplanetario (IDPs), algunas de las cuales pueden ser de origen cometario. Al igual que ocurre con los productos obtenidos por irradiación del hielo en nuestros experimentos, algunas IDPs son ricas en material orgánico que contiene oxígeno.

Prognostic Impact of del(17p) and del(22q) as Assessed by Interphase FISH in Sporadic Colorectal Carcinomas  

PubMed Central

Background Most sporadic colorectal cancer (sCRC) deaths are caused by metastatic dissemination of the primary tumor. New advances in genetic profiling of sCRC suggest that the primary tumor may contain a cell population with metastatic potential. Here we compare the cytogenetic profile of primary tumors from liver metastatic versus non-metastatic sCRC. Methodology/Principal Findings We prospectively analyzed the frequency of numerical/structural abnormalities of chromosomes 1, 7, 8, 13, 14, 17, 18, 20, and 22 by iFISH in 58 sCRC patients: thirty-one non-metastatic (54%) vs. 27 metastatic (46%) disease. From a total of 18 probes, significant differences emerged only for the 17p11.2 and 22q11.2 chromosomal regions. Patients with liver metastatic sCRC showed an increased frequency of del(17p11.2) (10% vs. 67%;p<.001) and del(22q11.2) (0% vs. 22%;p?=?.02) versusnon-metastatic cases. Multivariate analysis of prognostic factors for overall survival (OS) showed that the only clinical and cytogenetic parameters that had an independent adverse impact on patient outcome were the presence of del(17p) with a 17p11.2 breakpoint and del(22q11.2). Based on these two cytogenetic variables, patients were classified into three groups: low- (no adverse features), intermediate- (one adverse feature) and high-risk (two adverse features)- with significantly different OS rates at 5-years (p<.001): 92%, 53% and 0%, respectively. Conclusions/Significance Our results unravel the potential implication of del(17p11.2) in sCRC patients with liver metastasis as this cytogenetic alteration appears to be intrinsically related to an increased metastatic potential and a poor outcome, providing additional prognostic information to that associated with other cytogenetic alterations such as del(22q11.2). Additional prospective studies in larger series of patients would be required to confirm the clinical utility of the new prognostic markers identified.

Due to an error in transcription, the distance is given incorrectly in the text of ATel#5409. Along with the typo "Space Telescope Imaging Spectrograph", the text should read: Comparing these STIS UV spectra with high resolution IUE spectra of the CO nova OS And 1986 obtained between 12 days (LWP) and 22 days (SWP) after optical discovery (1986 Dec. 17, 27 respectively) shows a very close agreement such that when independently dereddened, the ratio of V339 Del to OS And between 1200 and 1900A is ~1.5 in flux (similar in the 2000-3000A range but more uncertain because of the earlier date of the long wavelength IUE observation), indicating that the distance to V339 Del is about 4.2 kpc (distance to OS And ~ 5.1 kpc with E(B-V)=0.25+/-0.05, see Schwarz et al.

The 2012 Reactivation of Nevado del Ruiz Volcano, Colombia  

NASA Astrophysics Data System (ADS)

Nevado Del Ruiz volcano is most known for its tragic November 13, 1985 explosive event, when a small eruption produced an enormous lahar that buried and destroyed the town of Armero in Tolima, causing an estimated 25,000 deaths. Similar but less deadly incidents occurred in 1595 and 1845, again where a small explosive eruption was followed by a large lahar. Other minor explosive events occurred in 1805, 1828-9, and 1989. The Armero tragedy was a major factor in the establishment of a volcano monitoring program in Colombia. The network monitoring Nevado del Ruiz volcano has dramatically improved since the 1985 eruption and now includes geodetic, geophysical, geochemical and visual monitoring. The activity of Nevado Del Ruiz between 1985 and 1991 saw significant increases in seismicity and significant gas emissions with the main eruptive events of November 13, 1985 and September 1st, 1989. The volcano became seismically active again in 1995 and 2002, whit an increase in seismicity, without any gas emission or eruption. In October 2010 the volcano entered in a new phase of unrest with increased seismicity (HB events), deformation and gas emissions, likely associated with a new magma intrusion. In February, 2012 the volcano had a new and significant increase in seismicity (VT-LP), followed in May and June 2012 by small phreatic and phreato-magmatic eruption. This eruptive activity is still ongoing. Deformation measurements at Nevado Del Ruiz volcano have been carried out since just after the tragic eruption of the 13th of November 1985. In 2007 seven new electronic tilt meters were set up to monitor the deformation. Significant uplift was measured from August 2007 to October 2010, for a total cumulative value of more than 500 microradians. From the end of 2011 to July 2012, moderate changes of uplift were detected for a total of 70 microradians. The analysis of these deformation data shows a pattern of surface displacement associated with an intrusion of new magma coming from a reservoir located approximately at a depth of approximately 8 km and accumulating in shallow reservoir less than 2 km beneath the main crater. We fit the data with both a spherical and a vertical spheroid source. The spherical source indicates the existence of an intrusion at a depth of 1823±1056 m with a volume change of (7±17)×106 m3 . The vertical spheroidal source suggests a source 1855 m deep with a volume change of 6×106 m3 . These results imply that while we have strong bounds on the depth of the intrusion, the actual volume of the source is less certain. Gas emission from Nevado del Ruiz volcano in April 7, 2012.

Mutations in TP53 are exclusively associated with del(17p) in multiple myeloma  

PubMed Central

Deletion of the 17p13 chromosomal region [del(17p)] is associated with a poor outcome in multiple myeloma. Most of the studies have targeted the TP53 gene for deletion analyses, although no study showed that this gene is the deletion target. In order to address this issue, we sequenced the TP53 gene in 92 patients with multiple myeloma at diagnosis, 54 with a del(17p) and 38 lacking del(17p). At least one mutation was found in 20 patients, all of them presenting a del(17p). The analysis of the mutation location showed that virtually all of them occurred in highly conserved domains involved in the DNA-protein interactions. In conclusion, we showed that 37% of the myeloma patients with del(17p) present a TP53 mutation versus 0% in patients lacking the del(17p). The prognostic significance of these mutations remains to be evaluated.

Hemizygous deletion of chromosome 22q11 (del22q11) causes thymic, parathyroid, craniofacial and life-threatening cardiovascular birth defects in 1 in 4,000 infants. The del22q11 syndrome is likely caused by haploinsufficiency of TBX1, but its variable expressivity indicates the involvement of additional modifiers. Here, we report that absence of the Vegf164 isoform caused birth defects in mice, reminiscent of those found in del22q11

Pragmatic evidence and textual arrangements: a case study of French clinical cancer guidelines.  


Both critics and supporters of evidence-based medicine view clinical practice guidelines as an important component of this self-defined "new paradigm" whose goal is to rationalize medicine by grounding clinical decision-making in a careful assessment of the medical literature. We present an analysis of the debates within a guideline development group (GDG) that led to the drafting, revision and publication of a French cancer guideline. Our ethnographic approach focuses on the various aspects of the dispositif (or apparatus) that defines the nature and roles of participants, procedures, topics and resources within the GDG. Debates between GDG members are framed (but not dictated) by procedural and methodological rules as well as by the reflexive critical contributions of the GDG members themselves, who justify their (tentative) recommendations by relating to its (possible or intended) audiences. Guideline production work cannot be reduced to an exchange of arguments and to consensus-seeking between pre-defined professional interests. It is about the production of a text in the material sense of the term, i.e. as a set of sentences, paragraphs, statements and formulations that GDG members constantly readjust and rearrange until closure is achieved. As such, guidelines partake in the emergence and stabilization of a new configuration of biomedical knowledge and practices grounded in the establishment of mutually constitutive links between two processes: on the one hand, the re-formatting of clinical trials into a device for producing carefully monitored evidence statements targeting specific populations and clinical indications and, on the other hand, the increasingly pervasive role of regulatory processes.

Engineering discovery learning: The contingency adduction of some precursors of textual responding in a beginning program  

PubMed Central

A learning situation in which the principal content of what is to be learned is not given but is independently discovered by the learner is often considered “discovery learning.” Recently, learning scientists have been able to make explicit some of the conditions under which such independent discovery is likely to occur (Andronis, 1983; Epstein, 1996; Johnson & Layng, 1992). One form of “discovery” can often be observed when skills learned under one set of conditions are recruited under new conditions to serve a new or different function—a process of “contingency adduction” (Andronis, Layng, & Goldiamond, 1997). The research reported here investigated the application of contingency adduction in a discovery learning context to establish sound-to-letter correspondence as part of an online reading/decoding program, Headsprout Early Reading. Beginning readers acquired novel letters/sounds correspondence with minimal presentations and few errors—often requiring only one presentation. This research suggests that instructional sequences may be designed to provide effective discovery learning activities to teach some phonics skills.

[Textual research on adulteration of Chinese materia medica in ancient China].  


By investigating the mainstream works of herbal classics of successive ages, it is found that adulteration of Chinese materia medica appeared early in ancient China. The main methods of adulteration was producing fraud medicines in the Northern-Southern Dynasties, fake medicines began to appear in the Tang Dynasty, and status of adulteration of Chinese materia medica ran unchecked since the Ming and Qing Dynasty. By statistics, there were 76 kinds of adulteration varieties before the Republican period. The main varieties were precious drugs, animal drugs and artifacts. Commonly methods used in the process included forging and adulterating, dealing with 11 kinds and 68 kinds respectively. Adulteration probably lead to the result of imposing the changes of the used medicinal parts of Herba Pogostemonis; Radix Aconiti Lateralis prepared by adding salt, Radix Angelica Sinensis processed by wine, and Radix Astragalis seu Hedysaris processed with bee honey. However, the root cause of adulteration in Chinese materia medica was the dissociation of professional physician and pharmacist, resulting in the ignorance of medical practitioners became unable to recognize Chinese materia medica; and the immorality of medicinal merchants. Besides, rating the quality of materia medica based on its producing areas without differentiating the false from the genuine may also contribute to this result passively. PMID:24429032

Integrating Query of Relational and Textual Data in Clinical Databases: A Case Study  

PubMed Central

Objectives: The authors designed and implemented a clinical data mart composed of an integrated information retrieval (IR) and relational database management system (RDBMS). Design: Using commodity software, which supports interactive, attribute-centric text and relational searches, the mart houses 2.8 million documents that span a five-year period and supports basic IR features such as Boolean searches, stemming, and proximity and fuzzy searching. Measurements: Results are relevance-ranked using either “total documents per patient” or “report type weighting.” Results: Non-curated medical text has a significant degree of malformation with respect to spelling and punctuation, which creates difficulties for text indexing and searching. Presently, the IR facilities of RDBMS packages lack the features necessary to handle such malformed text adequately. Conclusion: A robust IR+RDBMS system can be developed, but it requires integrating RDBMSs with third-party IR software. RDBMS vendors need to make their IR offerings more accessible to non-programmers.

Universal file format for products that allows both parametric and textual searching  

US Patent & Trademark Office Database

Methods are disclosed for loading a database for a computerized procurement system in a standard format that will allow suppliers in varying industries that have and have not standardized their nomenclature. The first step is for a supplier to put data describing an item into the CAE format. This format easily accommodates ISO, non-ISO, and UNSPSC compliant suppliers. The format is then converted into XML which allows for easy transmittal of the information on a computerized network. Thus anyone with access to the internet can relay this information to anyone else on the internet. The information is then deconverted back into the CAE file format once it is received by someone with a procurement database. The data is then stripped from the CAE format using a parser and properly loaded into a procurement database.

[Sick bodies textualized through images: what contemporary intensive care units can teach us].  


This paper belongs to a dissertation in which, what we have call "nursing worker cyborgizing" in intensive therapy is discussed. In order to carry out this discussion we based our work on cultural theorizing, as well as on Donna Haraway understanding of cyborg. For the corpses analysis manuals and assistance protocols were used. The methodological approach used in this work is the cultural analysis, as it has been used in the Poststructuralist Cultural Studies, in order to describe and analyze the production of images of sick bodies and its decoding process through a complex monitoring system in which sick bodies, machines and nursing practitioners, connect in different ways and effects. We have concluded that it is useful and relevant to consider and discuss these instances of production and diffusion of meanings attributed to the body, life, and the Nursing care. PMID:14692283

Using textual cause-of-death data to study drug poisoning deaths.  


Death certificate data are often used to study the epidemiology of poisoning deaths, but the International Classification of Diseases (ICD) codes used to tabulate death data do not convey all of the available information about the drugs and other substances named on death certificates. In the United States and some other countries, the SuperMICAR computer system is used to assign ICD codes to deaths. The SuperMICAR system also stores a verbatim record of the text entered for the cause of death. We used the SuperMICAR text entries to study the 7,817 poisoning deaths that occurred among Washington State residents between 2003 and 2010. We tabulated the drugs named on death certificates and computed age-adjusted and age-specific death rates for the top-named drugs and for prescription and illicit drugs. Methadone was named on 2,149 death certificates and was the most frequently named substance, followed by alcohol, opiate, cocaine, oxycodone, and methamphetamine. For both men and women and at all ages, prescription drugs were involved in more deaths than were illicit drugs. Among the 25 drugs named most frequently, only 4 have unique ICD codes; the other 21 can be identified only by using the SuperMICAR data. PMID:24521559

The index consists of a 'bibliographic' section and a keyword-section based on the permutation of. document titles, project titles, environmental impact statement titles, maps, etc. or lists of descriptors. The program can also create a back-of-the-book index to documents from a list of descriptors. By providing the user with a wide range of input and output options, the program provides the researcher, manager, or librarian with a means of-maintaining a list and index to documents in. a small library, reprint collection, or office file.

Estamos interesados en interpretar los excesos de flujo infrarrojo y/o ultravioleta observados en estrellas Be con respecto al de estrellas B normales, así como su posible correlación. Una envoltura rodeando la estrella distingue una estrella Be de una B normal; para explicar las observaciones es necesario entonces tener en cuenta todos los posibles procesos físicos que en ella tienen lugar. Adoptando un modelo atmosférico específico, hemos estudiado el proceso de recombinación dielectrónica de metales como MgII y FeII, teniendo en cuenta la posible influencia de la opacidad del medio en el flujo emitido.

Deadly Lahars from Nevado del Ruiz, Colombia: November 13, 1985  

NSDL National Science Digital Library

This web site describes a series of Lahars that occurred from the Nevado del Ruiz volcano in the Andes mountains, the northernmost and highest volcano in Colombia. Beginning in November 1984, the volcano began showing clear signs of unrest. An explosive eruption from Ruiz's summit crater on November 13, 1985, at 9:08 p.m. generated an eruption column and sent a series of pyroclastic flows and surges across the volcano's summit. Within minutes, pumice and ash began to fall to the northeast along with heavy rain that had started earlier in the day. Within four hours, lahars had traveled 100 km and left behind a wake of destruction: more than 23,000 people killed, about 5,000 injured, and more than 5,000 homes destroyed along the Chinchina, Guali, and Lagunillas rivers and destroying the town of Armero, Columbia. This deadly eruption of Nevado del Ruiz offers lessons on the generation of lahars for scientists, emergency-response professionals, and communities located downstream of such ice- and snow-covered volcanoes. The narrative is illustrated with 9 photographs.

Screening of antibacterial activity of Amaicha del Valle (Tucumán, Argentina) propolis.  


Propolis is extensively used in Argentine folk medicine. Alcoholic extracts of propolis from four localities of Amaicha del Valle (El Paraiso, La Banda Este, La Banda Oeste and El Molino), Province of Tucumán and from Cerrillos, Province of Santiago del Estero, Argentina were prepared. All showed antibacterial activity against Gram positive bacteria, the propolis from La Banda Este being the most active (MIC = 7.8 microg/ml) against Streptococcus piogenes, an antibiotic resistant bacterium. Thin layer chromatographic (TLC) separation profiles of propolis from Amaicha del Valle region were similar but differ from the alcoholic extract of the propolis from Cerrillos, another phytogeographical region of Argentina (provincia chaqueña). Bioautographic assays of the TLC profiles showed that several separated compounds of the Amaicha del Valle propolis have antibacterial activity. The difference in composition between Amaicha del Valle and Cerrillos propolis coincides with a different phytogeographical formation. PMID:10624867

Disruption of cytokeratin-8 interaction with F508del-CFTR corrects its functional defect  

PubMed Central

We have previously reported an increased expression of cytokeratins 8/18 (K8/K18) in cells expressing the F508del mutation of cystic fibrosis transmembrane conductance regulator (CFTR). This is associated with increased colocalization of CFTR and K18 in the vicinity of the endoplasmic reticulum, although this is reversed by treating cells with curcumin, resulting in the rescue of F508del-CFTR. In the present work, we hypothesized that (i) the K8/K18 network may interact physically with CFTR, and that (ii) this interaction may modify CFTR function. CFTR was immunoprecipitated from HeLa cells transfected with either wild-type (WT) CFTR or F508del-CFTR. Precipitates were subjected to 2D-gel electrophoresis and differential spots identified by mass spectrometry. K8 and K18 were found significantly increased in F508del-CFTR precipitates. Using surface plasmon resonance, we demonstrate that K8, but not K18, binds directly and preferentially to the F508del over the WT human NBD1 (nucleotide-binding domain-1). In vivo K8 interaction with F508del-CFTR was confirmed by proximity ligation assay in HeLa cells and in primary cultures of human respiratory epithelial cells. Ablation of K8 expression by siRNA in F508del-expressing HeLa cells led to the recovery of CFTR-dependent iodide efflux. Moreover, F508del-expressing mice topically treated with K8-siRNA showed restored nasal potential difference, equivalent to that of WT mice. These results show that disruption of F508del-CFTR and K8 interaction leads to the correction of the F508del-CFTR processing defect, suggesting a novel potential therapeutic target in CF.

Assessing Glacier Hazards At Ghiacciaio Del Belvedere, Macugnaga, Italian Alps  

NASA Astrophysics Data System (ADS)

The uppermost section of the Valle Anzasca behind and above the community of Macugnaga in the Italian Alps is one of the most spectacular high-mountain land- scapes in Europe, with gigantic rock walls and numerous steep hanging glaciers. Its main glacier, Ghiacciaio del Belvedere at the foot of the huge Monte Rosa east face, is a heavily debris-covered glacier flowing on a thick sediment bed. Problems with floods, avalanches and debris flows from this ice body have been known for extended time periods. Most recently, however, the evolution of this highly dynamic environ- ment has become more dramatic. An outburst of Lago delle Locce, an ice-dammed lake at the confluenec of the tributary Ghiacciaio delle Locce with Ghiacciaio del Belvedere, caused heavy damage in 1979 and necessitated site investigation and con- struction work to be done for flood protection. The intermittent glacier growth ten- dency in the 1970es induced strong bulging of the glacier surface and, in places, caused the glacier tongue to override historical morains and to destroy newly-grown forest stands. A surge-type flow acceleration started in the lower parts of the Monte- Rosa east face during summer 2000, leading to strong crevassing and deformation of Ghiacciaio del Belvedere and extreme bulging of its orographic right margin. High water pressure and accelerated movement lasted into winter 2001/2002: the ice now started overriding the LIA moraine near Rifugio Zamboni of the CAI. In addition but rather independently, a most active detachment zone for rock falls and debris flows developed for several years now in the east face of Monte Rosa, somewhat more to the south of the accelerated glacier movement and at an altitude where relatively warm permafrost must be expected. Besides the scientific interest in these phenomena, the growing hazard potential to the local infrastructure must be considered seriously. Es- pecially potentials for the destabilization of large rock and ice masses in the east face of Monte Rosa, for interruption of the access trail to the Rifugio Zamboni by overrid- ing and/or collapse of the lateral moraine, for impacts by ice invading various instal- lations (cable car, restaurant, ski runs, trails) near the moraine hill of Belvedere, and for sudden outbursts of pressurized subglacial water or the newly formed supraglacial lake must be envisaged.

Taphonomy of guanaco bones in Tierra del Fuego  

NASA Astrophysics Data System (ADS)

Guanaco carcasses are deposited in great quantities in Cabo San Pablo, Tierra del Fuego (Argentina), as a result of winter stress. Taphonomic studies indicate that the gnawing action of foxes on guanaco ( Lama guanicoe) carcasses produces only very tenuous marks on the bones. Lack of sustained interest in the carcasses by carnivores results in slow disarticulation. The articulated and disarticulated bones are exposed to heavy trampling by guanacos, a process that produces vertical migration of small/dense bones and fracturing of the most weathered bones. An understanding of this ongoing process is important for local archaeology, since modern bones are migrating into archaeological contexts. A regional approach to taphonomy is the most appropriate instrument to solve this and other related problems.

High precision ages from the Torres del Paine Intrusion, Chile  

NASA Astrophysics Data System (ADS)

The upper crustal bimodal Torres del Paine Intrusion, southern Chile, consists of the lower Paine-Mafic- Complex and the upper Paine-Granite. Geochronologically this bimodal complex is not well studied except for a few existing data from Halpern (1973) and Sanchez (2006). The aim of this study is to supplement the existing data and to constrain the age relations between the major magmatic pulses by applying high precision U-Pb dating on accessory zircons and 40Ar/39Ar-laser-step-heating-ages on biotites from the Torres del Paine Intrusion. The magmatic rocks from mafic complex are fine to medium-grained and vary in composition from quartz- monzonites to granodiorites and gabbros. Coarse-grained olivine gabbros have intruded these rocks in the west. The granitic body is represented by a peraluminous, biotite-orthoclase-granite and a more evolved leucocratic granite in the outer parts towards the host-rock. Field observations suggest a feeder-zone for the granite in the west and that the granite postdates the mafic complex. Two granite samples of the outermost margins in the Northeast and South were analyzed. The zircons were dated by precise isotope-dilution U-Pb techniques of chemically abraded single grains. The data are concordant within the analytical error and define weighted mean 206/238U ages of 12.59 ± 0.03 Ma and 12.58 ± 0.01 Ma for the two samples respectively. A 40Ar/39Ar-age for the second sample yield a date of 12.37 ± 0.11 Ma. Three 40Ar/39Ar -ages of biotites were obtained for rocks belonging to the mafic complex. A hbl-bio- granodiorite from the central part, approximately 150 m below the subhorizontal contact with the granite, gives an age of 12.81 ± 0.11 Ma. A hbl-bio-granodiorite and an olivine-gabbro west of the feeder-zone date at 12.42 ± 0.14 Ma and 12.49 ± 0.11 Ma, respectively. The obtained older age of 12.81 Ma for the granodiorite in the central part is consistent with structural relationships of brittle fracturing of the mafic complex by the granite and we conclude that some parts of the mafic complex were emplaced before the granite. The well defined 206/238U-age for zircons and the slightly younger 40Ar/39Ar -ages for biotites of both rock suites show that emplacement and cooling of the Torres del Paine Intrusion took place in a relatively short time-frame.

The first two algorithms involve simulation of Ricci flow, in complex and symplectic coordinates respectively. The third algorithm involves turning the PDE into an optimization problem on a certain space of metrics, which are symplectic analogues of the “algebraic” metrics used in numerical work on Calabi-Yau manifolds. Our algorithms should be applicable to general toric manifolds. Using our metric, we compute various geometric quantities of interest, including Laplacian eigenvalues and a harmonic (1,1)-form. The metric and (1,1)-form can be used to construct a Klebanov-Tseytlin-like supergravity solution.

Ozone studies in the Paso del Norte region  

NASA Astrophysics Data System (ADS)

The Paso del Norte region forms the largest contiguous bi-national conglomerate on the US-Mexico border. With a combined population of around 2 million inhabitants, the Paso del Norte region is isolated, more than 500 km away from the nearest urban area of comparable size, thus making it an ideal location for air quality studies of an isolated urban environment. The meteorological conditions leading to a high ozone episode in this region, such as the historical ozone episode of June 2006, are analyzed. It is well known that stagnation and minimal winds, high temperatures, and pressure ridges over the region are conducive to high ozone episodes. In addition, the planetary boundary height is studied to understand its impact on high ozone episodes. Several studies report that ground level ozone non-attainment regulations could be caused not only by local emissions, but also by atmospheric transport. In this work the atmospheric advection of pollutants into the region is analyzed using HYSPLIT backward trajectories. Furthermore, a novel backward trajectory clustering technique is implemented for the summer of 2006. The "ozone weekend effect" (OWE) is a phenomenon by which in some geographical regions ambient ozone concentrations tend to be higher on weekends than on weekdays, despite the lower emissions of ozone precursors during those days. The observed local OWE has never previously been studied in terms of the photolysis rates of four of the main ozone precursors. In this research a novel method that allows the calculation of actinic fluxes, photolysis frequencies and photolysis rates with a high degree of accuracy and reliability has been developed. This method utilizes a combination of the experimental data available for this region in conjunction with a radiative transfer model (TUV model). Three weekend-weekday cases during summers 2006, 2009 and 2010 are studied in this work. In this research, the photolysis impact on the local OWE is studied. The results obtained from this photolysis study demonstrate that the local ground level ozone formation is not only influenced by the strong solar radiation and changing aerosol makeup, but also by other heterogeneous factors and reactions. In addition, this research provided good evidence that the ground level ozone precursor regime in El Paso during the ozone episode of June 2006 was mostly VOC-limited. Much of this estimation was derived from measurements of local ambient VOC/NOx ratios. This finding shows that at least during June 2006, the non-linear surface ozone production increased during weekends compared to workdays in a habitually VOC-limited regime. The seasonal variations of columnar ozone as measured by a Multi-filter Rotating Shadowband instrument installed at the UTEP campus are analyzed for the first time for this region and results are presented. This investigation has addressed the problem of ground-level ozone formation in the Paso del Norte region. Urban ozone is a complex problem with many aspects that are not fully understood. In this investigation, a range of techniques has been used to address the study of local surface ozone episodes with the purpose of acquiring new insights and knowledge that will help understand and remediate the diverse atmospheric pollution events that affect this bi-national region recurrently. Innovative techniques were developed and used, ranging from the use of local ambient atmospheric pollution data to the utilization of complex modeling techniques to achieve the best possible computer results. Finally, the influence of ground level ozone concentrations in admissions to hospitals for this region due to respiratory diseases is analyzed. The comprehensive results obtained in this work will help to better understand ozone formation in the Paso del Norte Region for future policy regulation implementations.

Isotope hydrology of groundwaters in the Pampa del Tamarugal, Chile  

NASA Astrophysics Data System (ADS)

The water resources in northern Chile are extremely scarce and development is limited by this. This paper discusses the isotope hydrology of groundwaters in the Pampa del Tamarugal — an area of extreme aridity (rainfall < 1 mm/yr.) — whose groundwater resources are mined for the town of Iquique, as well as for industrial and agricultural purposes. The aim of the project was to obtain information on modern recharge and to delineate, if possible recharge environments. To obtain the necessary background information a precipitation survey in the high Andes, as well as spring- and surface-water studies were carried out. The results show that a well-defined meteoric water line exists where ? 2H = (7.8 ? 18O + 10.3)% , and altitude effects depend on air-mass movements and cannot be defined without a broader regional and detailed sampling programme. However, it is still possible to assign maximum altitudes of recharge to springs in the Andes and at the eastern border of the Pampa del Tamarugal. Comparison of these data with groundwater compositions show, that these groundwaters originate from infiltrating surface water rather than directly infiltrated precipitation. A dependence of individual groundwater systems on specific quebradas (river valleys) is recognized. However, low 14C activities indicate that most of the waters pumped today are fossil and at least several hundreds if not thousands of years old. Some minor subsurface recharge does occur at the foot of the Andes, especially at Pica where high-altitude waters discharge, but even there groundwater appears to be a diminishing resource.

[Progress in InDel as a new generation of genetic marker].  


As forensic DNA typing experienced three generations of genetic marker researching stage, short tandem repeat (STR) has been widely used in forensic identification as a mature tool. Further exploration of the human genome led to the discovery of polymorphism markers of single nucleotide polymorphism (SNP) and Insertion/Deletion (InDel). InDel, which combines the desirable characteristics of previous genetic markers as a new type of genetic marker, has got extensive concern in fields like medical molecular biology and forensic biology. This paper generally reviews the history of research and the corresponding results of InDel along the line of time axis as well as the different aims of these research focusing on the progress in the multiple amplification system with several InDel as the genetic marker (autosomal or X chromosome) in forensic biology and anthropology. Finally, the direction of research in this field and the problems to be solved have been put forward. PMID:23930511

The extracellular matrix protein Del1 induces apoptosis via its epidermal growth factor motif.  


Mouse Del1 is an extracellular matrix protein mainly expressed in the developing embryo. Del1 has three EGF motifs and two discoidin domains. The second EGF motif reportedly contains an RGD sequence that binds to integrin receptors. Here, we provide evidence that Del1 protein induces cell death in vitro. Chromatin condensation and DNA laddering were observed, suggestive of apoptosis. The results of analysis using the TUNEL method and annexin V staining were also consistent with apoptosis. The apoptosis-inducing activity of Del1 could be mapped to the third EGF motif, which fitted the consensus sequence CX(D/N)XXXX(F/Y)XCXC, wherein the aspartic acid residue (D) could be beta-hydroxylated. As little as twenty-five picomolar of recombinant E3 could induce apoptosis. PMID:20171188

[Molecular mechanism of RhDel phenotype in blood donation population of Chinese Harbin area].  


This study was aimed to explore the molecular mechanism of RhDel phenotype expression in blood donors of Chinese Harbin area. Three hundred and seventy-four RhD negative donors confirmed by indirect antiglobulin test were detected by using serological and molecular methods for red blood cell RhD blood group genotyping and RH gene variant detection. And the other special samples of undetermined RhD genotype were sequenced. The results showed that 62 cases of Del type were detected in 374 negative blood donors' samples, accounting for 16.6%, among them there were 61 cases of RHD1227A, and 1 case of rare RHD Del (cde) 1 allele was found. Sequencing analysis indicated that RHD711DelC allele existed in 11 cases. In addition, the new mutant alleles were found in 3 samples. It is concluded that RHD1227A allele is generally carried allele in Del phenotype population of Chinese Harbin area and is an important genetic marker in Del phenotype individual. PMID:23257457

Heterotic horizons, Monge-Ampère equation and del Pezzo surfaces  

NASA Astrophysics Data System (ADS)

Heterotic horizons preserving 4 supersymmetries have sections which are T 2 fibrations over 6-dimensional conformally balanced Hermitian manifolds. We give new examples of horizons with sections S 3 × S 3 × T 2 and SU(3). We then examine the heterotic horizons which are T 4 fibrations over a Kähler 4-dimensional manifold. We prove that the solutions depend on 6 functions which are determined by a non-linear differential system of 6 equations that include the Monge-Ampére equation. We show that this system has an explicit solution for the Kähler manifold S 2 × S 2. We also demonstrate that there is an associated cohomological system which has solutions on del Pezzo surfaces. We raise the question of whether for every solution of the cohomological problem there is a solution of the differential system, and so a new heterotic horizon. The horizon sections have topologies which include (( k - 1) S 2 × S 4# k( S 3 × S 3) × T 2 indicating the existence of exotic black holes. We also find an example of a horizon section which gives rise to two different near horizon geometries.

CASP8 -652 6N Del Polymorphism Contributes to Colorectal Cancer Susceptibility: Evidence from a Meta-Analysis  

PubMed Central

Objective Caspase-8 (CASP8) plays a central role in the apoptotic pathway and aberrant regulation of this pathway may cause cancers. Previous studies investigating the association between CASP8 -652 6N ins/del polymorphism and colorectal cancer (CRC) risk showed inconclusive results. We performed a meta-analysis of all available studies to investigate this association. Methods All studies published up to October 2013 on the association between CASP8 -652 6N ins/del polymorphism and CRC risk were identified by searching electronic databases PubMed, EMBASE, and Cochrane library. The association between CASP8 -652 6N ins/del polymorphism and CRC risk was assessed by odds ratios (ORs) together with their 95% confidence intervals (CIs). Results Six studies with 6,325 cases and 6,842 controls were included in the meta-analysis. We observed that the CASP8 -652 6N ins/del polymorphism was significantly correlated with CRC risk when all studies were pooled into the meta-analysis (ins/del vs. ins/ins: OR?=?0.890, 95%CI 0.821–0.964, P?=?0.004; del/del + ins/del vs. ins/ins: OR?=?0.899, 95%CI 0.833–0.970, P?=?0.006). In stratified analyses by ethnicity, source of control, and quality score, significant association was observed in Asians (ins/del vs. ins/ins: OR?=?0.862, 95%CI 0.761–0.977, P?=?0.020; del/del + ins/del vs. ins/ins: OR?=?0.845, 95%CI 0.749–0.953, P?=?0.006), population-based studies (ins/del vs. ins/ins: OR?=?0.890, 95%CI 0.813–0.975, P?=?0.012; del/del + ins/del vs. ins/ins: OR?=?0.901, 95%CI 0.827–0.982, P?=?0.018), and high quality studies. However, in subgroup analysis according to cancer location, no significant association was detected. Conclusions The present meta-analysis suggests that the CASP8 is a candidate gene for CRC susceptibility. The CASP8 -652 6N ins/del polymorphism may play a protective role in CRC development especially among Asians. Further large and well-designed studies are needed to confirm this association.

Screening for F508del as a first step in the molecular diagnosis of cystic fibrosis*,**  

PubMed Central

OBJECTIVE: To determine the relevance of screening for the F508del mutation of the cystic fibrosis transmembrane conductance regulator gene as a first step in the genetic diagnosis of cystic fibrosis (CF) by associating the genotype with various clinical variables. METHODS: We evaluated 180 CF patients regarding the F508del mutation. The clinical data were obtained from the medical records of the patients and from interviews with their parents or legal guardians. RESULTS: Of the 180 patients studied, 65 (36.1%) did not carry the F508del mutation (group 0 [G0]), 67 (37.2%) were F508del heterozygous (G1), and 48 (26.7%) were F508del homozygous (G2). All three groups showed associations with the clinical variables. Homozygosis was associated with younger patients, younger age at CF diagnosis, and younger age at the first isolation of Pseudomonas aeruginosa (PA), as well as with higher prevalence of pancreatic insufficiency (PI) and non-mucoid PA (NMPA) colonization. In comparison with G1+G2 patients, G0 patients were older; first experienced clinical symptoms, digestive disease, and pulmonary disease at an older age; were older at CF diagnosis and at first PA isolation; and had a lower prevalence of PI and meconium ileus, as well as of colonization by NMPA, mucoid PA, and Burkholderia cepacia. In G1 patients, values were intermediate for age at CF diagnosis; age at first PA isolation, first pulmonary symptoms, and first clinical manifestations; MPA colonization; and OR for PI. CONCLUSIONS: The identification of F508del in 63.9% of the patients studied showed that this can be a useful tool as a first step in the genetic diagnosis of CF. The F508del genotype was associated with clinical severity of the disease, especially with the variables related to CF onset.

Using Del-1 to tip the angiogenic balance in endothelial cells in modular constructs.  


Modular tissue engineering is a method of building vascularized tissue-engineered constructs. Submillimeter-sized collagen pieces (modules) coated with a layer of endothelial cells (EC; vascular component), and with embedded functional cells, are self-assembled into a larger, three-dimensional tissue. In this study, we examined the use of developmental endothelial locus-1 (Del-1), an extracellular matrix protein with proangiogenic properties, as a means of tipping the angiogenic balance in human umbilical vein endothelial cells incorporated in modular tissue-engineered constructs. The motivation was to enhance the vascularization of these constructs upon transplantation in vivo, in this case, without the use of exogenous mesenchymal stromal cells. EC were transduced using a lentiviral construct to overexpress Del-1. The Del-1 EC formed more sprouts in a fibrin gel sprouting assay in vitro compared with eGFP (control) transduced EC, as expected. Del-1 EC had a distinct profile of gene expression (upregulation of matrix metalloproteinase-9 [MMP-9], urokinase-type plasminogen activator [uPA/PLAU], vascular endothelial growth factor [VEGF-A], and intercellular adhesion molecule-1 [ICAM-1]; downregulation of angiopoietin-2 [Ang2]), also supporting the notion of "tipping the angiogenic balance". On the other hand, contrary to our expectations, when Del-1 EC-coated modules were implanted subcutaneously in a severe combined immunodeficient/beige animal model, the proangiogenic effect of Del-1 was less remarkable. There was only a small increase in the number of blood vessels formed in Del-1 implants compared with the eGFP implants, and only few blood vessels formed at the implant site in both cases. This was presumed due to limited EC survival after transplantation. We speculate that if we could improve EC survival in our study (for example, by adding other prosurvival factors or supporting cells), we would see a greater Del-1-induced angiogenic benefit in vivo as a consequence of increased Del-1 secretion by a higher number of surviving cells.

Magnetic fabric of the Torres del Paine, Patagonia  

NASA Astrophysics Data System (ADS)

The Miocene bimodal Torres del Paine Intrusive Complex (TIPC) consists of the lower Paine-Mafic-Complex (PMC) and the overlaying Paine Granite. Igneous structures (layering, xenolith orientations, and major contacts) are vertical in the westernmost part of the PMC, while they are sub-horizontal in the central and eastern parts. The TPIC is very homogeneous except in the PMC where complex interactions between mafic and felsic magmas were observed. No foliation or lineations are present in the field. Based on field-observations we distinguish at least three different sheet-like units in the Paine Granite, each one several tens to hundreds of meters thick. Younger sheets generally under-plate their precursor. We measured the anisotropy of magnetic susceptibility (AMS) on 145 samples from sites distributed horizontally over the entire surface of the TPIC and along 4 vertical profiles. The high intensity of the magnetic susceptibility for most of the Paine Granite and the PMC samples is due to the presence of magnetite. The magnetic lineations show a general WNW-ESE trend, parallel to the long axis of the intrusion. Lineations in the western part are strongly west-dipping to subvertical, parallel to the magmatic layering in the PMC. This supports the interpretation of a feeder-zone in that area. The lineations are sub-horizontal in the rest of the intrusion. Only minor variations in lineation orientation are observed in several hundred meter long vertical profiles in the central part of the Paine Granite. The magnetic foliations show the structural control exerted by the contact of the intrusion during its assembly: they are mostly horizontal in the central part, and are progressively steeper towards the contact. The low anisotropy is in agreement with the absence of texture observed in the field and thin sections. No sub-solidus deformation took place during the TPIC construction. The internal structures and magnetic fabrics support the interpretation of an intrusion assembled by horizontal transfer of magma in the form of sheet-like pulses stacking them vertically. Our results also show that the regional syn-magmatic deformation played no role in the emplacement of the TPIC.

The 1985 Nevado del Ruiz volcano catastrophe: anatomy and retrospection  

NASA Astrophysics Data System (ADS)

This paper seeks to analyze in an objective way the circumstances and events that contributed to the 1985 Nevado del Ruiz catastrophe, in order to provide useful guidelines for future emergencies. The paper is organized into two principal parts. In the first part, an Anatomy of the catastrophe is developed as a step-by-step chronicle of events and actions taken by individuals and organizations during the period November 1984 through November 1985. This chronicle provides the essential background for the crucial events of November 13. This year-long period is broken down further to emphasize essential chapters: the gradual awareness of the awakening of the volcano; a long period of institutional skepticism reflecting an absence of credibility; the closure of the credibility gap with the September 11 phreatic eruption, followed by an intensive effort to gird for the worst; and a detailed account of the day of reckoning. The second part of the paper, Retrospection, examines the numerous complicated factors that influenced the catastrophic outcome, and attempts to cull a few "lessons from Armero" in order to avoid similar occurrences in the future. In a nutshell, the government on the whole acted responsibly but was not willing to bear the economic or political costs of early evacuation or a false alarm. Science accurately foresaw the hazards but was insufficiently precise to render reliable warning of the crucial event at the last possible minute. Catastrophe was therefore a calculated risk, and this combination — the limitations of predication/detection, the refusal to bear a false alarm and the lack of will to act on the uncertain information available — provided its immediate and most obvious causes. But because the crucial event occurred just two days before the Armero emergency-management plan was to be critically examined and improved, the numerous circumstances which delayed progress of emergency management over the previous year also may be said to have contributed to the outcome. Thus the catastrophe was not caused by technological ineffectiveness or detectiveness, nor by an overwhelming eruption, or by an improbable run of bad luck, but rather by cumulative human error — by misjudgment, indecision and bureaucratic shortsightedness. Armero could have produces no victims, and therein dwells its immense tragedy.

Correlated Occurrence and Bypass of Frame-Shifting Insertion-Deletions (InDels) to Give Functional Proteins  

PubMed Central

Short insertions and deletions (InDels) comprise an important part of the natural mutational repertoire. InDels are, however, highly deleterious, primarily because two-thirds result in frame-shifts. Bypass through slippage over homonucleotide repeats by transcriptional and/or translational infidelity is known to occur sporadically. However, the overall frequency of bypass and its relation to sequence composition remain unclear. Intriguingly, the occurrence of InDels and the bypass of frame-shifts are mechanistically related - occurring through slippage over repeats by DNA or RNA polymerases, or by the ribosome, respectively. Here, we show that the frequency of frame-shifting InDels, and the frequency by which they are bypassed to give full-length, functional proteins, are indeed highly correlated. Using a laboratory genetic drift, we have exhaustively mapped all InDels that occurred within a single gene. We thus compared the naive InDel repertoire that results from DNA polymerase slippage to the frame-shifting InDels tolerated following selection to maintain protein function. We found that InDels repeatedly occurred, and were bypassed, within homonucleotide repeats of 3–8 bases. The longer the repeat, the higher was the frequency of InDels formation, and the more frequent was their bypass. Besides an expected 8A repeat, other types of repeats, including short ones, and G and C repeats, were bypassed. Although obtained in vitro, our results indicate a direct link between the genetic occurrence of InDels and their phenotypic rescue, thus suggesting a potential role for frame-shifting InDels as bridging evolutionary intermediates.

Correlated occurrence and bypass of frame-shifting insertion-deletions (InDels) to give functional proteins.  


Short insertions and deletions (InDels) comprise an important part of the natural mutational repertoire. InDels are, however, highly deleterious, primarily because two-thirds result in frame-shifts. Bypass through slippage over homonucleotide repeats by transcriptional and/or translational infidelity is known to occur sporadically. However, the overall frequency of bypass and its relation to sequence composition remain unclear. Intriguingly, the occurrence of InDels and the bypass of frame-shifts are mechanistically related - occurring through slippage over repeats by DNA or RNA polymerases, or by the ribosome, respectively. Here, we show that the frequency of frame-shifting InDels, and the frequency by which they are bypassed to give full-length, functional proteins, are indeed highly correlated. Using a laboratory genetic drift, we have exhaustively mapped all InDels that occurred within a single gene. We thus compared the naive InDel repertoire that results from DNA polymerase slippage to the frame-shifting InDels tolerated following selection to maintain protein function.

Observaciones del disco solar y de una protuberancia quiescente en radiación ultravioleta  

NASA Astrophysics Data System (ADS)

Observaciones del disco solar y de una protuberancia quiescente en el rango de longitudes de onda ultravioleta fueron obtenidas con el instrumento CDS (Coronal Diagnostic Spectrograph) y SUMER (Solar Ultraviolet Measurements of emitted radiation) a bordo de la sonda SOHO. El propósito es investigar las velocidades macroscópicas de varias especies metálicas que se observan tanto en el disco solar como en el plasma de las protuberancias. Para calcular las velocidades del disco solar aplicamos una técnica mixta para modelar la distribución de estructuras en UV en el Sol quieto. Las velocidades macroscópicas en las protuberancias se calcularon a partir de los corrimientos Doppler en cada línea espectral y luego se tomaron las del disco solar como referencia. Obtuvimos valores absolutos para las velocidades macroscópicas entre 5 y 40 km/seg. También detectamos comportamientos diferentes en las velocidades de las protuberancias en el centro con respecto a los bordes.

CASE REPORT: Phenotypic presentation of the Ser63Del MPZ mutation  

PubMed Central

Mutations in MPZ cause CMT1B, the second most frequent cause of CMT1. Elegant studies with Ser63del mice suggest that Ser63del MPZ is retained in the ER where it activates the unfolded protein response (UPR) that contributes to the neuropathy. Clinical information about patients with this mutation is limited. We present clinical and electrophysiological data on a large multigenerational family with CMT1B caused by Ser63del MPZ. The patients have a classical CMT1 phenotype that is much less severe than that of patients with Arg98Cys MPZ that also activates the UPR. These results suggest that clinical presentation along cannot predict which MPZ mutations will be retained in the ER and activate the UPR.

Biotic association and palaeoenvironmental reconstruction of the "Loma del Pterodaustro" fossil site (Early Cretaceous, Argentina)  

USGS Publications Warehouse

A sedimentological analysis of the basal section of the Early Cretaceous, lacustrine Lagarcito Formation at "Loma del Pterodaustro" (San Luis, Argentina) and a summary of its biological components are presented. Three sedimentological facies can be recognized in the basal sequence of the Lagarcito Formation. Fossil remains are particularly abundant in laminated claystones of a facies interpreted as deposits formed in offshore areas of the lake. The preservation of delicate structures allows recognition of these deposits as a Konservat Lagersta??tte. Up to now, rocks at "Loma del Pterodaustro" have yielded plants, conchostracans, semionotid and pleuropholid fishes, pterodactyloid pterosaurs, and a variety of invertebrate traces. The chronology of the Lagarcito Formation is discussed and it is concluded that this unit is of Albian age. The palaeoenvironment of deposition of the basal sequence of the Lagarcito Formation at "Loma del Pterodaustro" is interpreted as a perennial, shallow lake developed within an alluvial plain, under semiarid climatic conditions.

Origin and distribution of the BRCA2-8765delAG mutation in breast cancer  

PubMed Central

Background The BRCA2-8765delAG mutation was firstly described in breast cancer families from French-Canadian and Jewish-Yemenite populations; it was then reported as a founder mutation in Sardinian families. We evaluated both the prevalence of the BRCA2-8765delAG variant in Sardinia and the putative existence of a common ancestral origin through a haplotype analysis of breast cancer family members carrying such a mutation. Methods Eight polymorphic microsatellite markers (D13S1250, centromeric, to D13S267, telomeric) spanning the BRCA2 gene locus were used for the haplotype analysis. Screening for the 8765delAG mutation was performed by PCR-based amplification of BRCA2-exon 20, followed by automated sequencing. Results Among families with high recurrence of breast cancer (? 3 cases in first-degree relatives), those from North Sardinia shared the same haplotype whereas the families from French Canadian and Jewish-Yemenite populations presented distinct genetic assets at the BRCA2 locus. Screening for the BRCA2-8765delAG variant among unselected and consecutively-collected breast cancer patients originating from the entire Sardinia revealed that such a mutation is present in the northern part of the island only [9/648 (1.4%) among cases from North Sardinia versus 0/493 among cases from South Sardinia]. Conclusion The BRCA2-8765delAG has an independent origin in geographically and ethnically distinct populations, acting as a founder mutation in North but not in South Sardinia. Since BRCA2-8765delAG occurs within a triplet repeat sequence of AGAGAG, our study further confirmed the existence of a mutational hot-spot at this genomic position (additional genetic factors within each single population might be involved in generating such a mutation).

[Il ruolo del cervelletto nella depressione unipolare e bipolare: una rassegna delle principali evidenze neurobiologiche].  


riassunto. Evidenze derivanti da numerosi studi condotti sia su pazienti affetti da patologie cerebellari sia su soggetti sani suggeriscono che il cervelletto eserciti, oltre a un ruolo ormai ben definito nel controllo e nella regolazione delle funzioni motorie, una significativa attività di modulatore del tono dell'umore, del comportamento e delle funzioni cognitive. In questo lavoro di revisione abbiamo passato in rassegna tutti quegli studi di neuroimaging volti a indagare la presenza di alterazioni cerebellari sia morfologiche sia funzionali in pazienti affetti da disturbo bipolare (DB) e disturbo depressivo maggiore (DDM), ipotizzando l'esistenza di un meccanismo fisiopatologico alla base di questi disturbi, che coinvolga, almeno in parte, il cervelletto. Allo stesso scopo, sono stati esaminati anche quegli studi post mortem che indagavano la presenza di alterazioni cellulari e molecolari a partire da campioni di tessuto cerebellare, per esempio alterazioni delle proteine mitocondriali, della tirosin-chinasi B e del brain-derived neurotrophic factor (BDNF), del fattore di trascrizione SP4, della proteina fibrillare acida della glia (GFAP). In totale sono stati esaminati 28 studi, 12 inerenti le alterazioni morfologiche e funzionali del cervelletto nel DB, 13 inerenti le alterazioni morfologiche e funzionali del cervelletto nel DDM e 4 inerenti le alterazioni cerebellari post mortem in entrambi i disturbi. Dal nostro lavoro di revisione, in linea con quanto presente nella letteratura internazionale, emerge l'interessante ipotesi che il cervelletto funzioni come un "pacemaker emotivo" e che quindi una sua lesione potrebbe tradursi nell'incapacità dell'individuo di rimanere in equilibrio sulla sottile linea dell'eutimia, giustificando in questo modo la comparsa di profonde oscillazioni emotive sia sul versante depressivo sia su quello maniacale.

Haplotype analysis of the 185delAG BRCA1 mutation in ethnically diverse populations  

PubMed Central

The 185delAG* BRCA1 mutation is encountered primarily in Jewish Ashkenazi and Iraqi individuals, and sporadically in non-Jews. Previous studies estimated that this is a founder mutation in Jewish mutation carriers that arose before the dispersion of Jews in the Diaspora ?2500 years ago. The aim of this study was to assess the haplotype in ethnically diverse 185delAG* BRCA1 mutation carriers, and to estimate the age at which the mutation arose. Ethnically diverse Jewish and non-Jewish 185delAG*BRCA1 mutation carriers and their relatives were genotyped using 15 microsatellite markers and three SNPs spanning 12.5?MB, encompassing the BRCA1 gene locus. Estimation of mutation age was based on a subset of 11 markers spanning a region of ?5?MB, using a previously developed algorithm applying the maximum likelihood method. Overall, 188 participants (154 carriers and 34 noncarriers) from 115 families were included: Ashkenazi, Iraq, Kuchin-Indians, Syria, Turkey, Iran, Tunisia, Bulgaria, non-Jewish English, non-Jewish Malaysian, and Hispanics. Haplotype analysis indicated that the 185delAG mutation arose 750–1500 years ago. In Ashkenazim, it is a founder mutation that arose 61 generations ago, and with a small group of founder mutations was introduced into the Hispanic population (conversos) ?650 years ago, and into the Iraqi–Jewish community ?450 years ago. The 185delAG mutation in the non-Jewish populations in Malaysia and the UK arose at least twice independently. We conclude that the 185delAG* BRCA1 mutation resides on a common haplotype among Ashkenazi Jews, and arose about 61 generations ago and arose independently at least twice in non-Jews.

Parental origin of de novo deletions in the short arm of chromosome 9 in patients with a clinical diagnosis of del(9p) syndrome was assessed in 13 patients using polymerase chain reaction (PCR) analysis of highly polymorphic dinucleotide repeat microsatellite markers located in the putative deleted region. The deletion was found to be of paternal origin in 9 cases and of maternal origin in the remaining 4 cases, suggesting that the molecular event resulting in the deletion occurs in both male and female gametogenesis and that genomic imprinting does not appear to play a role in the pathogenesis of del(9p) syndrome. 22 refs., 1 fig.

Identification of a NBD1-binding pharmacological chaperone that corrects the trafficking defect of F508del-CFTR.  


Most cases of cystic fibrosis (CF) are attributable to the F508del allele of CFTR, which causes the protein to be retained in the endoplasmic reticulum (ER) and subsequently degraded. One strategy for CF therapy is to identify corrector compounds that help traffic F508del-CFTR to the cell surface. Pharmacological chaperones, or correctors that bind specifically to F508del-CFTR and restore function, would be the most promising drug development candidates, but few pharmacological chaperones exist for F508del-CFTR. Using differential scanning fluorimetry (DSF), we have surveyed corrector compounds and identified one, RDR1, which binds directly to the first nucleotide binding domain (NBD1) of F508del-CFTR. We show that RDR1 treatment partially rescues F508del-CFTR function in both cells and in an F508del-CF mouse model. Thus, RDR1 is a pharmacological chaperone of F508del-CFTR and represents a novel scaffold for drug development. PMID:21338920

A tectonically controlled basin-fill within the Valle del Cauca, West-Central Colombia  

SciTech Connect

Tertiary strata of the Valle del Cauca reflect a forearc/foreland basin tectonic history spanning a period from pre-uplift of the Cordillera Central to initiation of uplift of the Cordillera Occidental. Stratigraphy of the Valle del Cauca begins with Jurassic-Cretaceous rocks of exotic and/or volcanic provenance and of oceanic origin. Unconformably overlying these are Eocene to Oligocene basal quartz-rich sandstones, shallow marine algal limestones, and fine-grained fluvial/deltaic mudstones and sandstones with coalbeds. These Eocene to Oligocene deposits represent a period of low tectonic activity. During late Oligocene to early Miocene, increased tectonic activity produced conglomeratic sediments which were transported from east to west, apparently derived from uplift of the Cordillera Central, and deposited within a fluvial to deltaic setting. East-west shortening of the Valle del Cauca basin folded the Eocene to early Miocene units, and additional uplift of the Cordillera Central during the later Miocene resulted in syn-tectonic deposition of alluvial fans. After additional fold and thrust deformation of the total Eocene-Miocene basin-fill, tectonic activity abated and Pliocene-Quaternary alluvial and lacustrine strata were deposited. Within the framework of this depositional and tectonic history of the Valle del Cauca, hydrocarbon exploration strategies can be formulated and evaluated.
