Lineage delimitation and description of nine new species of bush frogs (Anura: Raorchestes, Rhacophoridae) from the Western Ghats Escarpment

Bush frogs of the genus Raorchestes are distributed mainly in the Western Ghats Escarpment of Peninsular India. The inventory of species in this genus is incomplete and there is ambiguity in the systematic status of species recognized by morphological criteria. To address the dual problem of taxon sampling and systematic uncertainty in bush frogs, we used a large-scale spatial sampling design, explicitly incorporating the geographic and ecological heterogeneity of the Western Ghats. We then used a hierarchical multi-criteria approach by combining mitochondrial phylogeny, genetic distance, geographic range, morphology and advertisement call to delimit bush frog lineages. Our analyses revealed the existence of a large number of new lineages with varying levels of genetic divergence. Here, we provide diagnoses and descriptions for nine lineages that exhibit divergence across multiple axes. The discovery of new lineages that exhibit high divergence across wide ranges of elevation and across the major massifs highlights the large gaps in historical sampling. These discoveries underscore the significance of addressing inadequate knowledge of species distribution, namely the ``Wallacean shortfall'', in addressing the problem of taxon sampling and unknown diversity in tropical hotspots. A biogeographically informed sampling and analytical approach was critical in detecting and delineating lineages in a consistent manner across the genus. Through increased taxon sampling, we were also able to discern a number of well-supported sub-clades that were either unresolved or absent in earlier phylogenetic reconstructions and identify a number of shallow divergent lineages which require further examination for assessment of their taxonomic status.

Differential proteomic and genomic profiling of mouse striatal cell model of Huntington's disease and control; probable implications to the disease biology

Huntington's disease (HD) is an autosomal dominant disorder of central nervous system caused by expansion of CAG repeats in exon1 of the huntingtin gene (Htt). Among various dysfunctions originated from the mutation in Htt gene, transcriptional deregulation has been considered to be one of the most important abnormalities. Large numbers of investigations identified altered expressions of genes in brains of HD patients and many models of HD. In this study we employed 2D SDS-PAGE/MALDI-MS coupled with 2D-DIGE and real-time PCR experiments of an array of genes focused to HD pathway to determine altered protein and gene expressions in STHdh(Q111)/Hdh(Q111) cells, a cell model of HD and compared with STHdh(Q7)/Hdh(Q7) cells, its wild type counterpart. We annotated 76 proteins from these cells and observed differential expressions of 31 proteins (by 2D-DIGE) involved in processes like unfolded protein binding, negative regulation of neuron apoptosis, response to superoxides etc. Our PCR array experiments identified altered expressions of 47 genes. Altogether significant alteration of 77 genes/proteins could be identified in this HD cell line with potential relevance to HD biology. Biological significance: In this study we intended to find out differential proteomic and genomic profiles in HD condition. We used the STHdh cells, a cellular model for HD and control. These are mouse striatal neuronal cell lines harboring 7 and 111 knock -in CAG repeats in their two alleles. The 111Q containing cell line (STHdh(Q111)/Hdh(Q111)) mimics diseased condition, whereas the 7Q containing ones (STHdh(Q7)/Hdh(Q7)), serves as the proper control cell line. Proteomic experiments were performed earlier to obtain differential expressions of proteins in R6/2 mice models, Hdh(Q) knock -in mice and in plasma and CSF from HD patients. However, no earlier report on proteomic alterations in these two HD cell lines and control was available in literature. It was, therefore, an important objective to find out differential expressions of proteins in these two cell lines. In this study, we annotated 76 proteins from STHdh(Q7)/Hdh(Q7) and STHdh(Q111)/Hdh(Q111) cells using 2D-gel/mass spectrometry. Next, by performing 2D-DIGE, we observed differential expressions of 31 proteins (16 upregulated and 15 downregulated) between these two cell lines. We also performed customized qRT-PCR array focused to HD pathway and found differential expressions of 47 genes (8 gene exptessions increased and 39 genes were decreased significantly). A total of 77 genes/proteins (Htt downregulated in both the studies) were found to be significantly altered from both the experimental paradigms. We validated the differential expressions of Vim, Hypk, Ran, Dstn, Hspa5 and Sod2 either by qRT-PCR or Western blot analysis or both. Out of these 77, similar trends in alteration of 19 out of 31 and 38 out of 47 proteins/genes were reported in earlier studies. Thus our study confirmed earlier observations on differential gene/protein expressions in HD and are really useful. Additionally, we observed differential expression of some novel genes/proteins. One of this was Hypk, a Htt-interacting chaperone protein with the ability to solubilize mHtt aggregated structures in cell lines. We propose that downregulation of Hypk in STHdh-Qm (Q111)/Hdh(Q111) has a causal effect towards HD pathogenesis. Thus the novel findings from our study need further research and might be helpful to understand the molecular mechanism behind HD pathogenesis. (C) 2015 Elsevier B.V. All rights reserved.

Algunas consideraciones sobre el pasado, presente y futuro de Europa

Resumen: El objetivo del presente trabajo es hacer un recorrido sobre los diversos lugares desde donde el pensamiento antiguo clásico ha abordado a “Europa” como concepto y como realidad. En primer lugar, indagando en sus testimonios se analizará cómo éstos fueron construyendo y transformando una conciencia geográfica del espacio territorial europeo. En segundo lugar, se esbozará la forma en que fue estructurándose, en principio, el “mito” de Europa como diosa, para luego ver cómo se estructuró la “idea” de Europa, afirmándose fundamentalmente en oposición al Asia y consolidándose en la asociación de continente y Cristiandad en tiempos medievales. Por último, se analizará el concepto como realidad histórica, para finalmente reflexionar brevemente sobre la situación de la cultura y cosmovisión europea en el siglo XX hasta hoy.

Lecciones de una crisis anunciada

Resumen: El autor examina las razones de la crisis actual e identifica dos clases de causas, las próximas, relacionadas con las particularidades específicas adoptadas por los mercados financieros, y las remotas, vinculadas a las transiciones culturales que acompañaron al cambio del capitalismo industrial al financiero Entre las causas próximas identificadas se encuentran la desregulación y la falta de supervisión del sector financiero iniciadas a partir de los años 70 en los EEUU, la necesidad de rendimientos cada vez mayores generada por los fondos de pensión y la utilización de modelos con supuestos y herramientas que, en última medida, subestimaban el riesgo de las inversiones. El segundo grupo, las causas remotas, esta compuesto por aquellas que cambiaron el marco cultural de la sociedad occidental. El autor sostiene que las teorías económicas sobre el accionar humano han logrado influenciarlo y que el paradigma de sociedad esta virando hacia uno que no incluye otro valor que la eficiencia, donde la empresa no es vista como una asociación sino como una mera mercancía.

El deán Gregorio Funes & Dámaso Antonio Larrañaga : evocando el pasado desde un presente revolucionario

Resumen: El avance que presentamos tiene el propósito de estudiar los antecedentes proto-historiográficos rioplatenses, a través del análisis del “Ensayo de la Historia civil de Buenos Aires, Tucumán y Paraguay”, del Deán Gregorio Funes, y del “Descubrimiento y Población de esta Banda Oriental del Río de la Plata. 1494 - 1818”, del Pbro. Dámaso Antonio Larrañaga. Ambos autores fueron eclesiásticos de acción destacada en el período revolucionario. Se establecerán ciertos ejes comparativos los cuales pretenden abarcar: 1) el periodo colonial, 2) el proceso revolucionario, 3) los límites geográficos por los cuales sobrevuelan los relatos, 4) los modos en que son descriptos los pueblos originarios, 5) los asuntos eclesiásticos y religiosos

El federalismo en el origen, consolidación, desarrollo y superación del constitucionalismo

Resumen: Los poderes territoriales predominaron en el nacimiento de los Estados en Europa occidental, en los que se advierten contrapesos entre órganos, de sustento consuetudinario y reconocimiento escrito de derechos. En la aparición y el afianzamiento del constitucionalismo escrito tienen singular importancia la transformación de confederaciones en Estados federales, en Estados Unidos, Suiza y Alemania; así como los procesos de Venezuela, Colombia, México, Brasil y Argentina. Su consolidación resulta de los sistemas de control de constitucionalidad: el difuso, que nace en Estados Unidos; y el concentrado, que comienza en Austria; ambos países federales. En la actualidad los Estados semicontinentales y las regiones de similares dimensiones pueden entenderse como superación del constitucionalismo, pues se ha modificado sustancialmente su ámbito geográfico, el cual resulta esencial para que la representación posea una inmediación suficiente y puedan funcionar los frenos y contrapesos que aseguran la moderación del poder. Una gran autonomía y fortaleza de las instituciones locales, es decir un auténtico federalismo, puede configurar un reaseguro suficiente para los objetivos iniciales del constitucionalismo: que el reconocimiento de los derechos y los equilibrios entre los titulares de poderes locales y centrales tengan la oportunidad de lograrse.

Ontologies for representation of folk song metadata

The digital management of collections in museums, archives, libraries and galleries is an increasingly important part of cultural heritage studies. This paper describes a representation for folk song metadata, based on the Web Ontology Language (OWL) implementation of the CIDOC Conceptual Reference Model. The OWL representation facilitates encoding and reasoning over a genre ontology, while the CIDOC model enables a representation of complex spatial containment and proximity relations among geographic regions. It is shown how complex queries of folk song metadata, relying on inference and not only retrieval, can be expressed in OWL and solved using a description logic reasoner.

Potential use of remote sensing to assess effects of wave action on plant re-establishment

Evaluation of the potential for remote sensing to detect a relationship between wave action factors and plant re-establishment after a habitat enhancement at Lake Kissimmee, Florida. Using Geographic Information Systems (GIS) and remote sensing, wave action factors were found to be inversely related to the probability of plant re-establishment. However, correlation of wave action factors with areal coverage of aquatic plants based on field measurements, were unable to detect a significant relationship. Other factors aside from wave action, including littoral slope and the presence of offshore vegetation, may have influenced plant re-establishment in these sites. Remote sensing techniques may be useful to detect large changes in plants communities, however small changes in plant coverages may not be detectable using this technique.

Using Remote Sensing and Spatial Information Technologies to Detect and Map Two Aquatic Macrophytes

This paper describes the light reflectance characteristics ofwaterhyacinth [Eichhornia crassipes (Mort.) Solms] and hydrilla [Hydrilla verticillata (L.F.) Royle] and the application of airborned videography with global positioning system (GPS) and geographic information system (GIS) technologies for distinguishing and mapping the distribution of these two aquatic weeds in waterways of southern Texas. Field reflectance measurements made at several locations showed that waterhyacinth generally had higher near-infrared (NIR) reflectance than associated plant species and water. Hydrilla had lower NIR reflectance than associated plant species and higher NIR reflectance than water. Reflectance measurements made on hydrilla plants submerged below the water surface had similar spectral characteristics to water. Waterhyacinth and hydrilla could be distinguished in color-infrared (CIR) video imagery where they had bright orange-red and reddish-brown image responses, respectively. Computer analysis of the imagery showed that waterhyacinth and hydrilla infestaions could be quantified. An accuracy assessment performed on the classified image showed an overall accuracy of 87.7%. Integration of the GPS with the video imagery permitted latitude/longitude coordinates of waterhyacinth and hydrilla infestation to be recorded on each image. A portion of the Rio Grande River in extreme southern Texas was flown with the video system to detect waterhyacinth and hydrilla infestaions. The GPS coordinates on the CIR video scenes depicting waterhyacinth and hydrilla infestations were entered into a GIS to map the distribution of these two noxious weeds in the Rio Grande River.
