Presión arterial : ¿esfigmomanómetro manual o digital?

El presente es un estudio prospectivo y comparativo entre la medición de la presión arterial obtenida de manera manual con esfigmomanómetro aneroide y la obtenida mediante monitor automático. El desarrollo de la práctica se realizó sobre un grupo de 100 pacientes hospitalizados en el servicio de Neurocirugía y Otorrinolaringología del Consorcio Hospital General de Valencia durante el primer trimestre del año 2007, mediante mediciones secuenciales y efectuadas por el mismo observador con ambos aparatos bien calibrados. Se observó mediante el método de correlación bivariada de Pearson que no existen diferencias estadísticamente significativas entre las presiones tomadas por ambos aparatos determinando así la fiabilidad del aparato automático utilizado en esta sala para el registro de la tensión arterial.This is a prospective and comparative work between arterial pressure obtained through manual measurement with aneroid sphygmomanometer and the arterial pressure obtained through automatic monitor. The practice was carried out in a group of 100 inpatients in the Neurosurgery and Otolaryngology Service in the Consortium of the General Hospital of Valencia during the first term of 2007. The development of this hospital training was made on each individual through sequential measurements and executed by the same observer with both well-calibrated machines. It was observed that through the method of Pearson's bivaried correlation there are not statistically significant differences between the pressures taken by both machines. As regards this fact, both automatic machines of arterial pressure register are [email protected] [email protected]

New method for carbon dioxide mineralization based on phosphogypsum and aluminium-rich industrial wastes resulting in valuable carbonated by-products

A new carbon mineralization method was designed based on a sequestration agent synthesised exclusively from industrial wastes. Phosphogypsum waste from the fertiliser industry was dissolved into caustic aqueous waste from the aluminium anodising industry. The resulting precipitate consisted of katoite (Ca3Al2(OH)12, a Si-free hydrogrossular solid solution end-member of the Al-containing hydrogarnet) and thenardite (Na2SO4); the latter easily removed by rinsing with water. The carbonation performance of this katoite-rich sequestration agent was evaluated using two different methods, by bubbling in aqueous media and by weathering. Both procedures yielded high carbonation efficiencies (80% and 100%, respectively), and resulted in a solid precipitate composed primarily of calcite (CaCO3) and aluminium hydroxide (Al(OH)3). Priority attention was given to the transfer of trace elements and radionuclides of the uranium series typically present in the phosphogypsum. Results confirmed that the traces were transferred to resulting final solid carbonate at concentrations similar to those present in the raw phosphogypsum. In conclusion, these carbonated minerals would trap substantial amounts of CO2 and produce final materials with similar civil engineering uses to those proposed for current phosphogypsum wastes. This work offers new methods for jointly managing specific industrial wastes oriented to more sustainable industrial processes and controlling CO2 emissionsGobierno de España MAT2013-42934- RJunta de Andalucía P12-RNM-226

Estudio fenológico y caracterización morfológica de variedades tradicionales de manzano y melocotonero

Las variedades locales de frutales seleccionadas a lo largo de los años por los agricultores, son muy interesantes para preservar la biodiversidad y los recursos fitogenéticos, ya que presentan unas características organolépticas peculiares y un valor cultural irremplazable. En 2007 se inició un trabajo de recuperación de variedades tradicionales de frutales en Andalucía (Proyecto INIA, RF2007-00027- C06-05) que contempla su prospección, localización, recogida de material vegetal, caracterización morfológica y molecular, multiplicación, documentación y mantenimiento en colección. En este trabajo se han caracterizado morfológicamente mediante caracteres UPOV las flores, hojas y ramos de un año, de cinco variedades tradicionales de manzano (Malus x domestica Borkh.) y dos de melocotonero [Prunus persica (L) Batsch], no estudiadas con anterioridad. Se ha evaluado la floración en la campaña 2011 y se han realizado los fenogramas correspondientesMICINN, INIA y Fondos FEDE

Methane dry reforming over Ni supported on pine sawdust activated carbon: Effects of support surface properties and metal loading

The influence of metal loading and support surface functional groups (SFG) on methane dry reforming (MDR) over Ni catalysts supported on pine-sawdust derived activated carbon were studied. Using pine sawdust as the catalyst support precursor, the smallest variety and lowest concentration of SFG led to best Ni dispersion and highest catalytic activity, which increased with Ni loading up to 3 Ni atoms nm-2. At higher Ni loading, the formation of large metal aggregates was observed, consistent with a lower "apparen" surface area and a decrease in catalytic activity. The H2/CO ratio rose with increasing reaction temperature, indicating that increasingly important side reactions were taking place in addition to MDR.Financial support was provided by CONICYT PFB-27 project (UDT-University of Concepción) and FONDECYT 1100884 grant

Fast-timing study of the l-forbidden 1/2+→3/2+ M1 transition in Sn129

R. Lică et al. ; 7 págs.; 5 figs.; 3 tabs. ; Open Access funded by Creative Commons Atribution Licence 3.0The levels in Sn129 populated from the β- decay of In129 isomers were investigated at the ISOLDE facility of CERN using the newly commissioned ISOLDE Decay Station (IDS). The lowest 12+ state and the 32+ ground state in Sn129 are expected to have configurations dominated by the neutron s12 (l=0) and d32 (l=2) single-particle states, respectively. Consequently, these states should be connected by a somewhat slow l-forbidden M1 transition. Using fast-timing spectroscopy we have measured the half-life of the 12+ 315.3-keV state, T12= 19(10) ps, which corresponds to a moderately fast M1 transition. Shell-model calculations using the CD-Bonn effective interaction, with standard effective charges and g factors, predict a 4-ns half-life for this level. We can reconcile the shell-model calculations to the measured T12 value by the renormalization of the M1 effective operator for neutron holes.This work was partially supported by the Spanish MINECO through Projects No. FPA2012-32443, No. FPA2013-41267-P, and CPAN Consolider (Project No. CSD-2007-00042), and by Romanian IFA Grant CERN/ISOLDE.

Musculoskeletal evaluation in severe haemophilia A patients from Latin America

There is a paucity of literature on haemophilia treatment in Latin American countries, a region characterized by rapidly improving systems of care, but with substantial disparities in treatment between countries. The aim of this study was to evaluate the musculoskeletal status of haemophilia patients from Latin America and to examine the relationship between musculoskeletal status and treatment practices across countries. The Committee of Latin America on the Therapeutics of Inhibitor Groups conducted a survey of its member country representatives on key aspects of haemophilia treatment in 10 countries. Musculoskeletal status of patients was obtained during routine comprehensive evaluations between March 2009 and March 2011. Eligible patients had severe haemophilia A (factor VIII <1%) without inhibitors (<0.6 BU mL−1) and were ≥5 years of age. Musculoskeletal status was compared between three groups of countries, based primarily on differences in the availability of long‐term prophylaxis. Overall, 143 patients (5–66 years of age) were enrolled from nine countries. In countries where long‐term prophylaxis had been available for at least 10 years (Group A), patients aged 5–10 years had significantly better mean World Federation of Hemophilia clinical scores, fewer target joints and fewer affected joints than patients from countries where long‐term prophylaxis has been available for about 5 years (Group B) or was not available (Group C). In Latin America, the musculoskeletal status of patients with severe haemophilia without inhibitors has improved significantly in association with the provision of long‐term prophylaxis. As more countries in Latin America institute this practice, further improvements are anticipated

Mechanisms of coronavirus pathogenicity and virus-host interactions

Trabajo presentado en la Conference on the Cooperation and Collaboration on Prevention and Control of Animal Diseases, celebrada en Hangzhou (China), del 21 al 23 de mayo de 2019Coronaviruses (CoVs) are important human and animal pathogens mainly causing respiratory and enteric infections with diverse severity. The presence of CoVs in bats, as animal reservoirs, and their ability for interspecies transmission have recently led to the emergence of novel CoVs responsible for epidemics in humans and livestock. In order to develop protection strategies against CoV infections, our laboratory is interested in the identification of (i) Viral factors involved in virulence and (ii) Host signaling pathways contributing to pathogenesis, using human coronaviruses SARS- and MERS-CoVs as model systems
