Open Journal of Pathology (OJPathology) , 2016, DOI: 10.4236/ojpathology.2016.63014
Abstract: This work presents the pathology description, isolation and identification of canine herpesvirus (CHV-1) in Mexico, a virus that causes a generalized hemorrhagic infection in puppies from the canidae family. Methods: Isolates were obtained from puppies that died within the first four weeks of life and had lesions consistent with canine herpesvirus. Results: The main gross lesions were petechial and ecchymotic hemorrhages in kidneys, liver and lungs; proliferative interstitial nephritis; multifocal necrosis in liver and kidneys; and encephalitis with intranuclear inclusion bodies. Herpesvirus was confirmed through direct immunofluorescence, electron microscopy and polymerase chain reaction for DNA polymerase and glycoprotein B genes. Discussion: Eight strains were isolated and identified as canine herpesvirus corresponding to three of the working cases with gross and microscopic lesions very similar to those described in the literature; then, isolates were confirmed by PCR gene amplification, positive reactions on immunofluorescence and observations from electron microscopy. This work represents the first report of this disease, including gross and histological lesions, and confirmation by isolation and identification of the canine herpesvirus in Mexico.

Abstract:
Canine herpesvirus (CHV-1) causes disease associated with high mortality in infect-ed puppies, which represents large financial losses for dog breeders. Since CHV-1 at the time of the study he had not been reported in Mexico, the main objective of this study was to determine the prevalence of antibodies against CHV-1 in canine kennels in the metropolitan area of Mexico City. A commercial enzyme-linked immuno-sorbent assay (ELISA) was used, and the results were compared to those of a viral neutralization test. The ELISA kit uses the complete viral particle as the antigen. The plaque reduction neutralization test was combined with the immunoperoxidase technique because of the low cytopathic effect of CHV-1. Neutralizing antibodies were also detected in 20 randomly selected samples. The prevalence of CHV-1 with ELISA was 87%. The concordance between ELISA and serum neutralization (SN) was 0.1129, the sensitivity of the ELISA against SN was 1.0 (100%), the positive predic-tive value was 0.39 (39%), and the negative predictive value was 1 (100%). These results show that ELISA is useful for monitoring the dog population for CHV-1; a positive test result requires confirmation with an SN test, and a negative ELISA result indicates a high probability of being SN-negative. The only variables that were sta-tistically associated with CHV-1 prevalence were breed and kennel. A statistically significant relationship between the degree of ELISA and SN titer was obtained, with a confidence level of 95%. None of the clinical presentation factors was statistically significant. These results suggest that most of the canine population studied in Mex-ico is in a herpesvirus latency state.
Laurent Phenomenon Sequences

Mathematics , 2013,
Abstract: In this paper, we undertake a systematic study of recurrences x_{m+n}x_{m} = P(x_{m+1}, ..., x_{m+n-1}) which exhibit the Laurent phenomenon. Some of the most famous among these sequences come from the Somos and the Gale-Robinson recurrences. Our approach is based on finding period 1 seeds of Laurent phenomenon algebras of Lam-Pylyavskyy. We completely classify polynomials P that generate period 1 seeds in the cases of n=2,3 and of mutual binomial seeds. We also find several other interesting families of polynomials P whose generated sequences exhibit the Laurent phenomenon. Our classification for binomial seeds is a direct generalization of a result by Fordy and Marsh, that employs a new combinatorial gadget we call a double quiver.
Investigation of DNA Sequences Related to Latency-Associated Transcripts in the Genome of Canine Herpesvirus Type 1 (CHV-1) by Means of Bioinformatics Tools  [PDF]

Abstract: A characteristic common to herpesviruses is the ability to establish a latent infection in the hosts, a transcriptionally active region has detected during latency as well as a set of RNA that are known as Latency Associated Transcripts (LATs), their functions have been clarified in recent work. The present work was carried using different bioinformatics method in order to determine if Herpesvirus Canine 1 (CHV-1) has a region associated with latency. Our result was the selection of nine sequences candidate of micro RNA (miRNA) (MIREval 2.0 software), and 26 miRNA (miRNAFold v.1.0 software), of them, were selected 14 with real precursors of miRNA, two were found between the RL2 and RS1 genes, one in the RL2 gene and 11 in the RS1 gene. The results showed that the similarities of these regions are very low among the herpesviruses analyzed, so it was not possible to deduce the presence of the LAT gene in canine herpesvirus type 1 with bioinformatics. On the other hand, the comparison showed that the miRNA predicted: chv1-mir-mirnafold-8 has similarity with the ebv-mir-BART7-3p of Epstein-Barr Virus (EBV), in this way, the microRNAs predicted by means of bioinformatic programs met the theoretical requirements of these molecules, however at not having a degree of preservation in other herpesviruses, the expression by CHV-1 in latency cannot be confirmed and it is necessary to identify through experimental tests.
Cancelling out systematic uncertainties

Abstract: We present a method to minimize, or even cancel out, the nuisance parameters affecting a measurement. Our approach is general and can be applied to any experiment or observation. We compare it with the bayesian technique used to deal with nuisance parameters: marginalization, and show how the method compares and improves by avoiding biases. We illustrate the method with several examples taken from the astrophysics and cosmology world: baryonic acoustic oscillations, cosmic clocks, Supernova Type Ia luminosity distance, neutrino oscillations and dark matter detection. By applying the method we recover some known results but also find some interesting new ones. For baryonic acoustic oscillation (BAO) experiments we show how to combine radial and angular BAO measurements in order to completely eliminate the dependence on the sound horizon at radiation drag. In the case of exploiting SN1a as standard candles we show how the uncertainty in the luminosity distance by a second parameter modeled as a metallicity dependence can be eliminated or greatly reduced. When using cosmic clocks to measure the expansion rate of the universe, we demonstrate how a particular combination of observables nearly removes the metallicity dependence of the galaxy on determining differential ages, thus removing the age-metallicity degeneracy in stellar populations. We hope that these findings will be useful in future surveys to obtain robust constraints on the dark energy equation of state.

Identidades sociales en jóvenes de sectores populares aproximaciones a un grupo de raperos
James Cuenca
Culturales , 2008,
Abstract: Este estudio se enfoca en la manera en que un grupo de jóvenes de sectores populares de Cali, Colombia, ha construido sus identidades sociales en relación con el rap. Los datos que se presentan como evidencia se apoyan en una investigación etnográfica hecha en 1998 y 2000 con grupos de raperos que tienen una fuerte ascendencia en esta ciudad. La discusión que se propone se centra, básicamente, en dos aspectos. Uno, caracterizar el tipo de identidad que los jóvenes construyen alrededor de esta oferta cultural y, dos, analizar estas identidades como un tipo de productividad simbólica que los jóvenes realizan para resistir y luchar contra las condiciones de pobreza y exclusión social en que viven.
“Inscrutable Intelligence”: The Case against Plastic Surgery in the Works of Jean Stafford and Sylvia Plath
Mercè Cuenca
Coolabah , 2009,
Abstract: Jean Stafford’s short story “The Interior Castle” (1946) and Sylvia Plath’s“Face Lift” and “The Plaster”, written in the early 1960s but published posthumously inCrossing the Water (1971), dwell on a theme which is rarely tackled in PostwarAmerican literature: plastic surgery. Using a markedly mnemonic tone, both authorstrace in detail the passive submission of female bodies to male (re)construction. Whilethe history of women in early Cold War America is usually associated with thepatriarchal mystifying of housewifery, the myth of ideal, domestic femininity was alsointimately related to bodily beauty. The demand for physical “perfection” whichresulted from constructing women as, primarily, objects of male desire was mirrored inpopular magazines, such as Ladies’ Home Journal, which endorsed women’s seekingmedical aid to model themselves into “ideal” sexual mates (Meyerowitz in Meyerowitzed., 244). Women’s submission to the notion that they should use any means necessaryto become aesthetic objects to be appraised by men was thus represented as desirable. Inthis paper, I shall trace how both Stafford and Plath adopted a confessional style ofwriting in the abovementioned pieces in order to denounce the cultural construction ofwomen as passive bodies to be moulded at will, instead of as active, thinking subjects. Ishall argue that by reproducing the recollections and thoughts of the women beingstitched, sewn and bandaged in their pieces, both authors articulated an alternativeprotofeminist aesthetics based on the beauty of what Stafford described as “inscrutableintelligence”.
Non-Gaussianity from Large-Scale Structure Surveys

Advances in Astronomy , 2010, DOI: 10.1155/2010/768675
Abstract: With the advent of galaxy surveys which provide large samples of galaxies or galaxy clusters over a volume comparable to the horizon size (SDSS-III, HETDEX, Euclid, JDEM, LSST, Pan-STARRS, CIP, etc.) or mass-selected large cluster samples over a large fraction of the extra-galactic sky (Planck, SPT, ACT, CMBPol, B-Pol), it is timely to investigate what constraints these surveys can impose on primordial non-Gaussianity. I illustrate here three different approaches: higher-order correlations of the three dimensional galaxy distribution, abundance of rare objects (extrema of the density distribution), and the large-scale clustering of halos (peaks of the density distribution). Each of these avenues has its own advantages, but, more importantly, these approaches are highly complementary under many respects. 1. Introduction The recent advances in the understanding of the origin and evolution of the Universe have been driven by the advent of high-quality data, in unprecedented amount (just think of WMAP and SDSS, e.g.). Despite this, most of the information about cosmological parameters come from the analysis of a massive compression of the data: the power spectrum of their statistical fluctuations over the mean. The power spectrum is a complete statistical description of a random field only if it is Gaussian. Even the simplest inflationary models predict deviations from Gaussian initial conditions. These deviations are expected to be small, although “small” in some models may be “detectable.” For a thorough review of inflationary non-Gaussianity see [1]; for our purpose it will be sufficient to say that to describe inflation-motivated departures from Gaussian initial conditions many write [2–5] Here denotes a gaussian field and denotes Bardeen's gauge-invariant potential, which, on sub-Hubble scales reduces to the usual Newtonian peculiar gravitational potential, up to a minus sign. In the literature, there are two conventions for (1): the large-scale structure (LSS) and the Cosmic Microwave Background (CMB) one. In the LSS convention is linearly extrapolated at ; in the CMB convention is instead primordial: thus , where denotes the linear growth suppression factor relative to an Einstein-de-Sitter Universes. In the past few years it has become customary to always report values even if, for simplicity as it will be clear below, one carries out the calculations with . While for simplicity one may just assume in (1) to be a constant (yielding the so-called local model or local-type) in reality the expression is more complicated and is scale and configuration
