Abstract: The primary aim of ANTARES is neutrino astronomy with upward going muons created in charged current muon neutrino interactions in the detector and its surroundings. Downward going muons are background for neutrino searches. These muons are the decay products of cosmic-ray collisions in the Earths atmosphere far above the detector. This paper presents a method to identify and count electromagnetic showers induced along atmospheric muon tracks with the ANTARES detector. The method is applied to both cosmic muon data and simulations and its applicability to the reconstruction of muon event energies is demonstrated. © 2012 Elsevier B.V.

153. The structure and optical activity of SrS2O6.4H2O

Abstract: The optical rotatory power of SrS2O6.4H2O was measured at room temperature along and perpendicular to the optic axis for a wavelength λ = 633 nm. The values ρ|| = 2.65 and ρ⊥ = −0.6° mm−1 were obtained, where || and ⊥ mean along and perpendicular to the optic axis, respectively. For the measurements of the optical activity along a birefringent crystal section, the so-called HAUP device (High-Accuracy Universal Polarimeter) has been used. The values of the different optical parameters have been successfully explained using the classical point-dipole–dipole polarizability theory and a recently determined ordered superstructure assigned to the space group P31. In this way, a connection between the absolute structure of the crystal and the sign of the optical rotation has been established. The conclusion is reached that the main contributors to the optical activity are the water oxygen atoms; in particular, the gyration along the optic axis is satisfactorily described by the exclusive effect of these atoms.

Abstract: The ANTARES collaboration has built a deep sea neutrino telescope in the Mediterranean Sea consisting of a matrix of pressure resistant glass spheres holding large area photomultipliers. The aim of the telescope is to observe cosmic neutrinos through the Cerenkov light induced in sea water by charged particles produced in neutrino interactions with the surrounding medium. A relative time calibration between photomultipliers of the order of 1 ns is required to achieve an optimal performance. To this end, several time calibration subsystems have been developed for the whole telescope. In this article, the design, tests and integration of the last Laser Beacon model, developed to measure and monitor the relative time offsets between photomultipliers, are described.

Abstract: A study of inclusive production of the meson resonances ρ0, K*0 (892), f{hook}0 (975) and f{hook}2 (1270) in hadronic decays of the Z0 is presented. The measured mean meson multiplicity per hadronic event is 0.83 ± 0.14 for the ρ0 0.64 ± 0.24 for the K*0 (892), 0.10 ± 0.04 for the f{hook}0 (975) in the momentum range p > 0.05pbeam (xp > 0.05) and 0.11 ± 0.05 for the f{hook}2 (1270) for xp > 0.1. These values and the corresponding differential cross sections ( 1 σhadr) dσ dxp for the vector mesons are in good agreement with the predictions of the JETSET 7.3 PS and HERWIG 5.4 models. The f{hook}2 (1270) production is overestimated by HERWIG but its xp-shape is correctly reproduced. The measured ratios of the production cross sections σ(f{hook}2(1270)) σ(ρ0) = 0.22 ± 0.08 and σ(f{hook}2(1270)) σ(f{hook}0(975)) = 3-1 +7 for xp > 0.1 are consistent with the results obtained in hadronic reactions. © 1993.

Abstract: Starting from a given Markov kernel on a finite set $V$ and a bijection $g$ of $V$, we construct and study a time inhomogeneous Markov chain whose kernel at time $n$ is obtained from $K$ by transport of $g^{n-1}$. We show that this construction leads to interesting examples, and we obtain quantitative results for some of these examples., Published in at http://dx.doi.org/10.1214/09-AAP661 the Annals of Applied Probability (http://www.imstat.org/aap/) by the Institute of Mathematical Statistics (http://www.imstat.org)

158. Anisotropic chemical etching of semipolar [1011]/[101+1] ZnO crystallographic planes: polarity versus dangling bonds

Author: E, Palacios-Lidón, B, Pérez-García, P, Vennéguès, J, Colchero, V, Muñoz-Sanjosé, and J, Zúñiga-Pérez
Abstract: ZnO thin films grown by metal-organic vapor phase epitaxy along the nonpolar [formula: see text] direction and exhibiting semipolar [formula: see text] facets have been chemically etched with HCl. In order to get an insight into the influence of the ZnO wurtzite structure in the chemical reactivity of the material, Kelvin probe microscopy and convergent beam electron diffraction have been employed to unambiguously determine the absolute polarity of the facets, showing that [formula: see text] facets are unstable upon etching in an HCl solution and transform into [formula: see text] planes. In contrast, [formula: see text] facets undergo homogeneous chemical etching perpendicular to the initial crystallographic plane. The observed etching behavior has been explained in terms of surface oxygen dangling bond density, suggesting that the macroscopic polarity plays a secondary role in the etching process.

159. Prevalencia y distribución espacial de brucelosis, leucosis bovina, diarrea viral bovina y rinotraqueítis infecciosa bovina a partir del análisis ELISA de estanques prediales en lecherías de la IX Región, Chile

Abstract: Chile es reconocido internacionalmente por poseer una buena situación sanitaria pues el país ha podido alcanzar y mantener el estado de oficialmente libre de las principales enfermedades de la lista de la OIE. Sin embargo, aún coexisten en nuestros rebaños bovinos una serie de enfermedades, las cuales tienen un directo impacto en la producción, por cuanto disminuyen la fertilidad, producen pérdidas por aborto, alargan el lapso interparto y fundamentalmente constituyen barreras sanitarias para la exportación, ya que constituyen un riesgo de zoonosis para la población. En este trabajo se implementó un sistema de vigilancia predial basado en el análisis ELISA de muestras de leche del estanque, para estudiar la epidemiología y distribución espacial de cuatro de las principales enfermedades bovinas que afectan a la IX Región de Chile (brucelosis, leucosis bovina, DVB e IBR). Este sistema permitió monitorear el estado de estas enfermedades en 279 lecherías, cobertura que representó al 43% de las lecherías registradas en la IX Región, abarcando 19.635 vacas lecheras (14%). Con este sistema se pudo establecer por primera vez en la Región una alta prevalencia en la muestra para leucosis (59%), IBR (76%) y DVB (96%), mientras que se confirmó que brucelosis se encuentra restringida a unas pocas lecherías (5%). Este sistema de monitoreo predial acoplado al análisis espacial (SIG) permitió establecer la distribución de estas enfermedades en las distintas comunas de la Región, demostrando ser una valiosa herramienta de apoyo y de bajo costo para la vigilancia epidemiológica de enfermedades en el rebaño lechero, lo que avala la posibilidad de establecer dicha plataforma como sistema de vigilancia predial en la Región y su factibilidad de proyectarla a nivel nacional.

Abstract: We develop singular value techniques in the context of time inhomogeneous finite Markov chains with the goal of obtaining quantitative results concerning the asymptotic behavior of such chains. We introduce the notion of c-stability which can be viewed as a generalization of the case when a time inhomogeneous chain admits an invariant measure. We describe a number of examples where these techniques yield quantitative results concerning the merging of the distributions of the time inhomogeneous chain started at two arbitrary points.

Abstract: The total and differential cross-sections for the reaction e+e- → γγ(γ) are measured at centre of mass energies around 91 GeV using an integrated luminosity of 4.7 pb-1. The aggreement with QED prediction is good. Consequently there is no evidence for non-standard channels which would have the same experimental signature. The lower limits on the QED cuttoff parameters are Λ+ > 113 GeV and Λ- > 95 GeV. An upper limit on the effective coupling between a possible excited electron and the gamma is derived. At 95% confidence level the branching ratios for Z0 decay into π0γ, ηψ and γγγ are below 1.5 × 10-4, 2.8 × 10-4 and 1.4 × 10-4 respectively., 0, info:eu-repo/semantics/published

Abstract: The incommensurate structure of BCCD at 130 K with q = 0.296c∗ has been determined in the superspace-group P(Pnma):(1, s, −1) by means of single crystal X-ray diffraction data including main and first-order satellite reflections. Only zero and first-order harmonics have been considered in the modulation functions. The final agreement factors are R = 0.048, Ro = 0.042 and R1 =0.067, for all, main and first-order satellite reflections respectively. Only the atomic modulations of the betaine molecule could be interpreted in terms of rigid-body modulated motions. The symmetry of the structure is in accordance with a single A3 soft-mode model for the phase transition sequence.

Abstract: Restraint equations suitable for incommensurate (IC) structure refinement by least squares are defined. Other quantities used in the final results analysis are reviewed. The main purpose of such a restrained refinement is to prevent high local variations of stereochemical parameters (e.g. bond lengths and/or angles), leaving the corresponding average values to be refined. The method is a natural generalization of that commonly used for commensurate structures and in some cases does not require user-supplied parameters.

165. Detection of a SERK-like gene in coconut and analysis of its expression during the formation of embryogenic callus and somatic embryos

Abstract: Somatic embryogenesis involves different molecular events including differential gene expression and various signal transduction pathways. One of the genes identified in early somatic embryogenesis is S OMATIC E MBRYOGENESIS R ECEPTOR-like K INASE (SERK). Cocos nucifera (L.) is one of the most recalcitrant species for in vitro regeneration, achieved so far only through somatic embryogenesis, although just a few embryos could be obtained from a single explant. In order to increase efficiency of this process we need to understand it better. Therefore, the purpose of the present work was to determine if an ortholog of the SERK gene is present in the coconut genome, isolate it and analyze its expression during somatic embryogenesis. The results showed the occurrence of a SERK ortholog referred to as CnSERK. Predicted sequence analysis showed that CnSERK encodes a SERK protein with the domains reported in the SERK proteins in other species. These domains consist of a signal peptide, a leucine zipper domain, five LRR, the Serine-Proline-Proline domain, which is a distinctive domain of the SERK proteins, a single transmembrane domain, the kinase domain with 11 subdomains and the C terminal region. Analysis of its expression showed that it could be detected in embryogenic tissues before embryo development could be observed. In contrast it was not detected or at lower levels in non-embryogenic tissues, thus suggesting that CnSERK expression is associated with induction of somatic embryogenesis and that it could be a potential marker of cells competent to form somatic embryos in coconut tissues cultured in vitro.

Abstract: A programmable digital circuit typically consists of a microprocessor, a memory device, an input data device and an output data device, with its corresponding communication busses. These devices work following a program which is stored in the memory device, as codified instructions. An opto-electronic system that emulates a programmable digital circuit is proposed and described in this work. This circuit is commanded by a sequential program stored as a spatial distribution of Fourier Holograms into a photorefractive crystal. The sequential program is conformed by instructions, which have been codified as binary pixels maps. To read and decode each instruction, the spatial position of the photorefractive crystal must change; and then a CCD camera captures the output image of the Fourier Hologram. Our LabVIEW software decodes the instruction from the captured output image and it commands the circuit to realize the decoded instruction. This software controls the CCD camera and an electromechanical system which moves the spatial position of the photorefractive crystal. The electromechanical system is continuously in communication with a PC through our software. This is because the electronic circuit of the electromechanical system, moves three stepper motors; depending on the position in which the crystal needs to be to read the next instruction. The experimental results and the complete description of the practical advantages and disadvantages of the complete engineering system and the emulation of the opto-electronic programmable digital circuit will be described in this work.

Abstract: Despite many previous investigations, the symmetry and structure of thiourea in its modulated configuration is still under discussion. We report here a new determination of this structure by means of X-ray diffraction, using a rigid-body model for the molecular units. The diffraction diagram up to third order satellites was measured in the commensurate phase with q=1/9b*, the structure refinement being performed however in the superspace formalism. The superspace group P(Pnma):(sT1) describes adequately the structure symmetry, allowing excellent results in the refinement. The anharmonicity of the modulation functions is considerable, with non negligible contributions of second and third harmonics. Despite theoretical predictions on the contrary, the form of the rigid-body modulation functions indicate a certain soliton regime. At a final stage of the refinement the possible modulation of the atomic thermal tensors was also considered. The results evidence a significant second harmonic modulation ...

Abstract: ANTARES is a neutrino telescope being deployed in the Mediterranean Sea. It consists of a three dimensional array of photomultiplier tubes that can detect the Cherenkov light induced by charged particles produced in the interactions of neutrinos with the surrounding medium. High angular resolution can be achieved, in particular when a muon is produced, provided that the Cherenkov photons are detected with sufficient timing precision. Considerations of the intrinsic time uncertainties stemming from the transit time spread in the photomultiplier tubes and the mechanism of transmission of light in sea water lead to the conclusion that a relative time accuracy of the order of 0.5 ns is desirable. Accordingly, different time calibration systems have been developed for the ANTARES telescope. In this article, a system based on Optical Beacons, a set of external and well-controlled pulsed light sources located throughout the detector, is described. This calibration system takes into account the optical properties of sea water, which is used as the detection volume of the ANTARES telescope. The design, tests, construction and first results of the two types of beacons, LED and laser-based, are presented., 21 pages, 18 figures, submitted to Nucl. Instr. and Meth. Phys. Res. A

172. Estudio comparativo de un PCR anidado, ELISA y AGID en la detección del virus de la leucosis bovina en muestras de suero, sangre y leche

Abstract: Se evaluaron distintos métodos actualmente disponibles para el diagnóstico de la infección por el virus de la leucosis bovina (VLB). Los métodos empleados fueron AGID en suero, ELISA en muestras de suero y leche y PCR en linfocitos sanguíneos. De un total de 126 animales analizados, AGID identificó un menor número de animales positivos (75) comparado con las pruebas PCR y ELISA aplicadas en muestras de suero y leche (100). Tres animales positivos a AGID fueron negativos a PCR y 28 de las 51 muestras negativas a AGID fueron positivas mediante PCR. La sensibilidad diagnóstica de PCR con respecto a AGID fue de 96%, mientras que la especificidad fue de 45% (kappa 0,45). Todos los animales positivos a AGID fueron también positivos a ELISA aplicado tanto en suero como en leche, mientras que 25 animales negativos a AGID fueron consignados como positivos a ELISA, en ambas muestras biológicas. De esta forma, la sensibilidad diagnóstica de ELISA respecto a AGID fue de un 100%, mientras que la especificidad fue de 51% (kappa 0,55). La menor sensibilidad observada de AGID no es debido a reacciones falso positivas de ELISA y PCR, sino más bien a una mayor sensibilidad de estas últimas, lo que sugiere reconsiderar la utilización del método AGID en aquellos países en que aún se utiliza como método oficial en los programas de erradicación de leucosis.

Abstract: In 2005, the ANTARES Collaboration deployed and operated at a depth of 2500 m a so-called Mini Instrumentation Line equipped with Optical Modules (MILOM) at the ANTARES site. The various data acquired during the continuous operation from April to December 2005 of the MILOM confirm the satisfactory performance of the Optical Modules, their front-end electronics and readout system, as well as the calibration devices of the detector. The in-situ measurement of the Optical Module time response yields a resolution better than 0.5 ns. The performance of the acoustic positioning system, which enables the spatial reconstruction of the ANTARES detector with a precision of about 10 cm, is verified. These results demonstrate that with the full ANTARES neutrino telescope the design angular resolution of better than $0.3^\circ$ can be realistically achieved., Comment: 18 pages, 12 figures, submitted to Astroparticle Physics

Abstract: The aim of this study was to assess the suitability of using DNA isolated from milk somatic cells for the diagnosis and molecular typing of bovine leukaemia virus (BLV). A total of 40 bulk milk samples were analysed and thirty three of them resulted seropositive to BLV after being evaluated using an indirect ELISA test. A PCR test confirmed the presence of the virus in all 33 seropositive samples whereas in the remaining seronegative samples it was not possible to detect a specific band for the virus. A RFLP analysis identified 2 out of the 3 known subgroups of BLV genetic variants. Individual analysis carried out in the PCR positive herd confirmed the presence of more than one genetic variant within this herd, suggesting that there is a possibility of re-infection occurring with another virus strain. This report is the first to describe the application of a PCRRFLP test for the detection and molecular typing of BLV directly from milk samples. The simplicity of collecting bulk milk samples makes the described technique a convenient way for a quick diagnosis of the virus, which can also be used to study the molecular epidemiology and distribution of BLV infection in a specific area or even at national scale. &nbsp, Se evaluó la factibilidad de aplicar una prueba de PCR para el diagnóstico y tipificación molecular del virus de la leucosis enzoótica bovina (VLB), directamente desde muestras de leche. Se analizó un total de 40 muestras de estanque predial, 33 de las cuales fueron seropositivas a una prueba de ELISA. El PCR confirmó la presencia del virus en el 100% de los estanques seropositivos, mientras que en las muestras seronegativas no se obtuvo una banda de amplificación. El posterior análisis de estas muestras mediante RFLP permitió identificar la presencia de 2 de los 3 subgrupos conocidos de variantes genéticas del virus. La aplicación de esta prueba en 10 animales de un predio permitió confirmar la presencia de más de una variante genética dentro del mismo predio, sugiriendo la probable reinfección de este predio con otras cepas del virus. Es necesario destacar que este trabajo constituye el primer reporte de la aplicación de una prueba de PCR-RFLP para la detección y tipificación del VLB directamente desde muestras de leche. De esta forma, la técnica de PCR descrita se puede utilizar no sólo como complemento al diagnóstico del VLB, sino también como una forma conveniente de realizar la tipificación del virus en una zona determinada o incluso a nivel de país, lo cual proporciona una forma rápida y conveniente de estudiar la epidemiología y distribución de la infección del VLB en nuestros rebaños. &nbsp

Abstract: The ANTARES neutrino telescope, to be immersed depth in the Mediterranean Sea, will consist of a 3 dimensional matrix of 900 large area photomultiplier tubes housed in pressure resistant glass spheres. The selection of the optimal photomultiplier was a critical step for the project and required an intensive phase of tests and developments carried out in close collaboration with the main manufacturers worldwide. This paper provides an overview of the tests performed by the collaboration and describes in detail the features of the PMT chosen for ANTARES., Comment: 21 pages, 10 figures.

Abstract: The methanol extract of the rhizomes of Scirpus californicus (Cyperaceae) inhibited the enzyme xanthine oxidase (XO) in vitro. Bioassay-guided isolation led to piceatannol, scirpusin A and scirpusin B as the main XO inhibitors of S. californicus. Piceatannol, scirpusin A and B were mixed-type inhibitors of the XO with X 1 values of 1.1 x 10 -4 , 6 x 10 -4 and 5 x 10 -5 M, respectively. The extract and above mentioned compounds were marginally active as hypotensors when tested in normotensive rats at 2.5 mg/kg and were inactive towards the DNA binding assay in vitro.

Abstract: The acetone-water extract of Hexachlamys edulis (Myrtaceae) inhibited the enzyme xanthine oxidase (XO) in vitro. Bioassay-guided isolation led to the gallic acid ester in 2 of myricitrin (desmanthia-1), (-)-epigallocatechin-3-O-gallate (EGG) and pentagalloylglucose as the main XO inhibitors of H. edulis. Desmanthin-1 and EGG were mixed-type inhibitors of XO with K i values of 1.6 x 10 -4 M and 1.8 x 10 -4 M, respectively. Pentagalloylglucose was an uncompetitive XO inhibitor with a K EsI of 6.7 x 10 -6 M. From the active n-butanol soluble part of the aqueous acetone extract of H. edulis, several flavonoids were isolated. The flavonoids were mainly myricetin-3-O-monoglycosides with the quercetin glycoside avicularin as a minor compound displaying a weak inhibitory activity towards XO.

Abstract: The electronic and structural properties of ${\mathrm{In}}_{100\ensuremath{-}x}{\mathrm{Se}}_{x}$ liquid alloys close to their melting points have been investigated by combining x-ray-absorption experiments with ab initio molecular-dynamics simulations. Extended x-ray-absorption fine-structure data have been acquired at both the In and Se K edges in a large concentration range $(x=20%$ to $x=50%$ of Se content). Ab initio molecular-dynamics simulations have been carried out at the two most extreme concentrations explored experimentally. Liquid InSe is found to retain a semiconducting behavior which results from a low-dimensional structure, reminiscent of that of the ambient solid phase, characterized by strong In-Se interactions within tetrahedral units. On the other side, the ${\mathrm{In}}_{80}{\mathrm{Se}}_{20}$ liquid alloy shows a metalliclike behavior which is correlated to a more dense-packed structure.

Abstract: Since 1972, the relationship between HLA alleles and the susceptibility for Takayasu arteritis (TA) has been studied on different populations. Hence the results up to date are heterogeneous, the objective of the present review is to analyze the relationship between the presence of HLA alleles and the susceptibility for the development of TA considering the ethnic origin of the studied populations.We carried out a bibliographic review from clinical articles of case and controls studies on different populations on which the relationship between HLA alleles and the susceptibility for TA was studied, published since 1972 until February 2000.We reviewed articles of studies on Asian, Arab, North-American and Mexican Mestizo populations. On Asian populations TA was associated with HLA-A31, -B52, -B39, -B5 and -DR2, on Arabs with HLA-A2, -A9, -B35 and -DR7, on North-Americans with HLA-DR4 and on Mexican Mestizo with HLA-B5, -B52 and -DR6. On the other hand, recent reports establish that several HLA-B alleles (HLA-B52 and HLA-B39) associated with the disease share some residues important on the antigen presentation.Hence the heterogeneity of the results obtained up to date, it stands out the increase on HLA-B52 and HLA-DR4 reported on ethnically different populations. More recent data point the possible participation of an epitope located on the peptide-binding site of the HLA-B molecule (positions 63 and 67) that seems to be shared by several alleles associated with the disease. These residues might be participating on the presentation of an unknown antigen that would unchain the disease on the genetically susceptible individuals group.

Subjects: Diffraction, Materials science, Optics, Cinnabar, business.industry, High pressure, Lattice (order), Hexagonal phase, Analytical chemistry, business
Abstract: We have performed an energy-dispersive x-ray-diffraction experiment on ${\mathrm{ZnSe}}_{1\ensuremath{-}x}{\mathrm{Te}}_{x}$ alloys under high pressure with $x=0,$ 0.05, 0.1, and 0.2. In the downstroke a hexagonal phase appears. We suggest that this phase is cinnabar, whose stability range decreases as the Te content is reduced. The analysis of the whole series of compositions enables us to establish its lattice parameters in ZnSe $(a=3.785\AA{}$ and $c=8.844\AA{}$ at 10.5 GPa). The extinction of some diffraction peaks also suggests that the internal parameters u and $v$ are close to 0.5, indicating that the cinnabar phase in ZnSe is similar to that observed in GaAs and ZnTe.

183. [Genetic determinant factors of resistance to HIV infection and of control of progression to AIDS: implications on pathogenesis and therapeutic approaches for the eradication of HIV. A review]

Author: J, Zúñiga, G, Vargas-Alarcón, N, Salgado, C, Flores, S, Martínez-Tripp, A, Miranda, A, Balbuena, N, Osnaya, F, Juárez, J, Granados, and G, Reyes-Terán
Subjects: Major Histocompatibility Complex, Acquired Immunodeficiency Syndrome, Disease Progression, Cytokines, Humans, HIV Infections
Abstract: In this review, we describe and discuss the genetic factors that, up to some point, determine resistance to the infection and control the progression of the disease in HIV-infected individuals. Genetic factors may account for non-progression or slow progression of the disease in some of so called long-term non progressors HIV-infected individuals. In general, this group shows no symptoms for more than 10 years, while their circulating T CD4+ cells levels remain stable and they usually have a low virus load. Even though non-progression and rapid progression phenomenon are still not fully understood, there probability exists that some class I and class II MHC alleles are associated with a greater or smaller risk to develop AIDS. Class I HLA-B*35 and Cw*04 alleles are the ones commonly associated with the rapid transition of the infection into AIDS. In contrast, heterozygosity for class I HLA alleles and, particularly, the absence of HLA-B*35 and Cw*04 may contribute to non-progression. Studies which set forward other HLA alleles as possibly taking part of the pathogenic mechanism of non-progression are also described; although, relevant methodological problems can be noticed. Furthermore, this review explains and discusses allelic variations for some of the components of the chemokine receptors family, particularly the genes which codify for CCR5 and CCR2 and other genetic factors such as the SDF1-3'. A variant of the alpha SDF1 chemokine gene that have been associated with AIDS' slow progression or non-progression in HIV-infected individuals. As a whole, the factors described in this review are those that influence the natural history of the disease due to HIV and give an example of what genetic or multigenetic influence can have over the pattern of evolution of HIV infection. Finally, we mention the possible implications that the identification of the genetic markers has in the pathogenesis of HIV disease and in the development of the new therapeutic strategies to control or eliminate HIV.

Abstract: The purpose of this study is to describe a single-center experience in primary coronary angioplasty in 304 consecutive patients with acute myocardial infarction. Sixty-seven percent were men and 33% women, the mean age was 69 years. The time from onset to treatment was 3.5 hours, 14% had previous bypass surgery and 23% prior myocardial infarction, 11% arrived in cardiogenic shock. Coronary angiography showed multivessel disease in 56% of patients, 73% had TIMI 0-1 flow. Successful PTCA occurred in 95% and in hospital mortality was 6.5%. Primary coronary angioplasty is a successful reperfusion method in acute myocardial infarction and it is associated with low mortality even in high risk groups. The rates of success and major complications in this series are similar to other publications.

Abstract: 10 págs.; 7 figs.; 1 tab., The structures of the liquid, glass (i.e., amorphous), rotator-phase (RP) crystal, orientational glass (OG), and the stable (monoclinic) crystal phases of ethanol are investigated by means of neutron and x-ray diffraction. The RP crystal and OG phases show an intermediate kind of disorder between that of the fully disordered glass and liquid phases and that of the stable crystal. The Bragg pattern of the RP and OG crystals provides information about the time-averaged distribution of single-molecule orientations, and a contribution comprising intermodular correlations is isolated from the diffuse intensity. Finally, the RP→OG rotational freezing transition is analyzed in detail and shown to constitute a physical realization of the glass transition found in hard-needle models. ©1997 American Physical Society, This work was performed in part under DGICYT (Spain) Grant No. PB95-0072-C03-01.

187. Comparison among DNA polymerases 1, 2 and 3 from maize embryo axes. A DNA primase activity copurifies with DNA polymerase 2

Abstract: Three DNA polymerase activities, named 1, 2 and 3 were purified from maize embryo axes and were compared in terms of ion requirements, optimal pH, temperature and KCl for activity, response to specific inhibitors and use of templates. All three enzymes require a divalent cation for activity, but main differences were observed in sensitivity to inhibitors and template usage: while DNA polymerases 1 and 2 were inhibited by N-ethyl maleimide and aphidicolin, inhibitors of replicative-type enzymes, DNA polymerase 3 was only marginally or not affected at all. In contrast, DNA polymerase 3 was highly inhibited by very low concentrations of ddTTP, an inhibitor of repair-type enzymes, and a 100-fold higher concentration of the drug was needed to inhibit DNA polymerases 1 and 2. Additionally, DNA polymerases 1 and 2 used equally or more efficiently the synthetic template polydA-oligodT, as compared to activated DNA, while polymerase 3 used it very poorly. Whereas DNA polymerases 1 and 2 shared properties of replicative-type enzymes, DNA polymerase 3 could be a repair-type enzyme. Moreover, a DNA primase activity copurified with the 8000-fold purified DNA polymerase 2, strengthening the suggestion that polymerase 2 is a replicative enzyme, of the alpha-type. This DNA primase activity was also partially characterized. The results are discussed in terms of relevant data about other plant DNA polymerases and primases reported in the literature.

Abstract: From the data recorded with the DELPHI detector at LEP in the years 1991–1992, 46497 events were selected having a high-momentum muon in hadron jets. A fit to the average electric charge sum of the jets recoiling against a b-quark jet tagged by a high-PT muon results in an average mixing parameter of View the MathML source.

Abstract: Ventricular dysfunction is the most common cause of in-hospital death in patients with acute myocardial infarction. When cardiogenic shock is manifested the mortality is very high. Seven patients with cardiogenic shock complicating acute myocardial infarction were treated with emergency coronary angioplasty. Four patients required cardiopulmonary resuscitation (CPR), 2 intraaortic balloon pump support and one femoro-femoral bypass pump support during the coronary angioplasty. The angiography success rate was 86%. Two patients died, one in the catheterization laboratory and the other one 24 hours later. The hospital mortality was 29%. Of the patients who survived 4 are in functional class I and one in functional class II (NYHA). Coronary angioplasty therapy in patients with cardiogenic shock complicating acute myocardial infarction plays a decisive role in the reduction of mortality.

Abstract: During the last two decades, the clinical presentation of primary hyperparathyroidism (PHP) has changed due to the routine use of multiphasic biochemical screening tests. We assessed 84 patients with PHP treated in our service between 1977 and 1991. The yearly incidence increased from 1.6 to 7.6 patients/year with the introduction of multiphasic biochemical testing in our hospital in 1982; likewise the proportion of asymptomatic patients increased from 12.5 to 40.7%. The most frequent presenting symptoms were bone pain and renal colic. Nineteen percent of patients were over 70 years old and this age group had distinct clinical features. The plasma chlorine/phosphorus ratio was abnormal in 95% of cases; on the contrary only 7 of 18 patients had a urinary calcium excretion over 300 mg/day. Cervical ultrasound, performed in 45 patients had a positive predictive value of 78% to localize the lesion. Bone density was below fracture threshold in 50% of studied patients. The principal surgical finding was the presence of adenoma. Twenty one percent of patients had symptomatic hypocalcemia during the first week after surgery; however, only 2.5% of patients continued to have hypocalcemia one month after surgery. One patient had an inferior laryngeal nerve damage and two a cervical hematoma. It is concluded that the introduction of massive calcium measurements has allowed an early diagnosis of asymptomatic PHP, specially in elderly people.

Abstract: The tau lepton lifetime is measured using four different methods with the DELPHI detector. Three measurements using one prong decays are combined, accounting for correlations, resulting in tau(tau) = 298 +/- 7 (stat.) +/- 4 (syst.) fs while the decay length distribution of three prong decays gives tau(tau) = 298 +/- 13 (stat.) +/- 5 (syst.) fs. The combined result is tau(tau) = 298 +/- 7 fs. The ratio of the Fermi coupling constant from tau decay relative to that from muon decay is found to be 0.985 +/- 0.013, compatible with lepton universality.

Abstract: Distributions of event shape variables obtained from 120600 hadronic Z decays measured with the DELPHI detector are compared to the predictions of QCD based event generators. Values of the strong coupling constant αs are derived as a function of the renormalization scale from a quantitative analysis of eight hadronic distributions. The final result, αs(MZ), is based on second order perturbation theory and uses two hadronization corrections, one computed with a parton shower model and the other with a QCD matrix element model. © 1992 Springer-Verlag.

Abstract: Using a data sample of 115000 hadronic Z0 decays, a search was performed for the production of excited charged leptons decaying into an ordinary lepton and one photon. Pair production of excited leptons of mass below 45 GeV/c2 is excluded. From an analysis of the lepton-photon mass spectra this experiment is also able to exclude single production of these particles for masses that reach up to 85 GeV/c2, if the compositeness scale is below 1 TeV. © 1992 Springer-Verlag, 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: The average lifetime of B hadrons produced in hadronic Z0 decays has been measured with the DELPHI detector at LEP. The measurement is based on the analysis of the impact parameter distributions of high pt muons and hadrons. The resulting mean B lifetimes are τB=(1.30±0.10±0.08)ps and τB=(1.27±0.04±0.12)ps respectively, giving a combined value of τB=(1.28±0.10)ps. The hadronic sample was also used to measure the partial Z0 width {Mathematical expression} and gave a value of 0.222-0.031+0.033±0.017. © 1992 Springer-Verlag., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: The differential cross section for final state radiation from primary quarks is obtained from a study of isolated energetic photons produced in the reaction e+e-→Z0→hadrons+γ, as measured in the DELPHI detector at the CERN LEP collider. When combined with the measurement of the total hadronic width of the Z0, the observed rate determines the electroweak coupling constants of up and down type quarks, i.e. {Mathematical expression} No evidence is seen for additional photon production from anomalous decays of the Z0 or from decays of new particles. This measurement leads to upper limits on the production cross section times branching fraction of (a) the Higgs boson in the reaction e+e-→Z0→H +γ, H→hadrons, (b) an excited quark, q*→q+γ, and (c) the contribution of an anomalous decay of the Z0 into a photon and hadrons. These limits, all at the 95% confidence level, vary from 3 to 10pb as the mass of the intermediate state (H, q* or Z*) varies from 10 GeV/c2 to 80 GeV/c2. © 1992 Springer-Verlag, 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: The spectra of prompt electrons and muons from the semi-leptonic decays of heavy hadrons produced inZ 0 decays have been used to measure the coupling of theZ 0 tob quarks weighted by theB hadrons mean semi-leptonic branching fraction, giving a value: $$BR_{sl}^b *{{\Gamma _{b\bar b} } \mathord{\left/ {\vphantom {{\Gamma _{b\bar b} } {\Gamma _H }}} \right. \kern-\nulldelimiterspace} {\Gamma _H }} = 0.0221 \pm 0.0015$$ . The data has also been used to measure the value of the fragmentation parameter, defined in the context of the LUND PS Model, version 7.2, giving: $$\varepsilon (b) = \left( {8\begin{array}{*{20}c} { + 5} \\ { - 3} \\ \end{array} \pm 2} \right)10^{ - 3} $$ . The corresponding value of the mean fraction of the beam energy taken by aB hadron in the fragmentation of ab quark is: $$\overline {X_E^b } = 0.69\begin{array}{*{20}c} { + 0.02} \\ { - 0.03} \\ \end{array} \pm 0.01$$ . If the values of $$\Gamma _{b\bar b} $$ andΓ H are taken from the Standard Model, the following value is obtained for the mean semi-leptonic braching fraction ofB hadrons: BR sl =(10.1±0.7)%. Taking the value of $${{\Gamma _{b\bar b} } \mathord{\left/ {\vphantom {{\Gamma _{b\bar b} } {\Gamma _{\rm H} }}} \right. \kern-\nulldelimiterspace} {\Gamma _{\rm H} }}$$ from an independent analysis of DELPHI data based on the use of the boosted sphericity product, a value: BR sl =(10.1±1.3)% is obtained.
