Simiele Narvarte,A.; Novoa Sanjurjo,F.; Gómez Rodríguez,N.; Antón Badiola,I.;
Anales de Medicina Interna , 2004, DOI: 10.4321/S0212-71992004001200006
Abstract: erdheim-chester disease is an idiopathic systemic histiocytosis hystologically different to langerhans histiocytosis which is characterized by symmetric sclerotic bone lesions, predominantly affecting the diaphyseal and metaphyseal areas of large bones. it is not classified within malignant histicytosis, but the clinical course tends to be agressive with a poor reponse to different schedules of treatment. in rare cases the association of both entities has been reported: erdheim-chester disease and langerhans histiocytosis. we present a new case with histological data of both histiocytosis whose clinical course included bone and muscle pain, insipidus diabetes, exophthalmos, bilateral symmetrical sclerosing bone lesions and a cerebellar syndrome.

Abstract: spinal cord compression and radicular involvement are infrequent events in the natural history of non-hodgkin?s lymphoma, which usually are secondary to invasion of spinal extradural space, and rarely are the presenting manifestations of this condition. thoracic segment is predominantly affected, but any spinal region can be affected. histologically, the spinal tumour are frequently a high-grade b lymphoma with aggressive behaviour. the aim of this work was to describe six new cases of non-hodgkin?s lymphoma in adults (five woman and one men), presenting with spinal neurological complications. the medical literature about this entity are revised.
HACIA UN ESTATUTO FISCAL DEL AUTONOMO. REFLEXIONES DE FUTURO SOBRE EL REGIMEN FISCAL DEL AUTONOMO/TOWARDS A FISCAL STATUTE OF THE AUTONOMOUS . REFLECTIONS OF FUTURE ON THE FISCAL REGIME OF THE AUTONOMOUS
César GARCíA NOVOA
Revista de Estudios Cooperativos , 2008,
Abstract: El concepto de trabajador autónomo tiene gran importancia desde la perspectiva fiscal. Es difícil admitir el concepto Estatuto Fiscal, pero sí es necesaria la reforma del régimen fiscal del autónomo. El autónomo es persona física y en el impuesto sobre la renta hay que garantizar la posibilidad de deducir todos los gastos relacionados con su actividad. Es necesario defender también la simplificación, siendo el mejor instrumento los impuestos objetivos en el Impuesto sobre la Renta y en el IVA. Debe suprimirse el llamado recurso permanente de las Cámaras de Comercio./The concept of autonomous worker is very important from the fiscal perspective. It is difficult to admit the concept Fiscal Statute. But there is necessary the reform of the tax regime of the autonomous. The autonomous one is a natural person. In the income tax it is necessary to guarantee the possibility of deducing all the expenses related to his activity. We must defend also the simplification. The best instruments are the objective taxes in the Income tax and in the VAT. There must be suppressed the so called recurso permanente of the Chambers of Commerce.
Análisis estadístico de los registros de ruido electroquímico obtenidos en la corrosión del aluminio
Sánchez, A.,Sanjurjo, M.,Bouzada, F.,Urréjola, S.
Revista de Metalurgia , 2005,
Abstract: Given that the experimental signals obtained in an electrochemical noise measurement, ENM, are recorded over a discrete time period, the most direct way of analising them will be in the time domain resorting to statistical methods. These can be classified into two groups according to use: those which attempt to quantify the degree of the corrosion process (standard deviations, statistical power); and those which attempt to provide information on the corrosion mechanism (based on the assumption that the shape of the time records is a reflection of itself). Among the later the use of the average, the skewness and the kurtosis of the signals or the pitting index can be pointed out as being able to reflect the changes in the corrosion mechanism. Noise resistance stands out above all these parameters. In this work has undertaken the statistical treatment of ENM data obtained by subjecting aluminium to three electrolytes that provoke several types of corrosion in it: passivity, pitting corrosion and generalized corrosion. En la mayoría de los experimentos sobre ruido electroquímico, ENM (Electrochemical Noise Measurement), las se ales experimentales se registran durante períodos de tiempo discretos. Resulta habitual, por ello, que en las publicaciones sobre esta técnica, la forma más directa de analizar esos datos consiste en acudir a métodos estadísticos en el dominio temporal. Estos métodos pueden ser clasificados, según su utilidad, en dos grupos: aquellos que pretenden cuantificar la magnitud del proceso de corrosión (desviaciones estándar, potencia estadística, etc.) y los que tratan de extraer información sobre el mecanismo del proceso corrosivo en sí mismo, los cuales se basan, en su mayoría, en la suposición de que la forma de los registros temporales son un reflejo del comportamiento de la interfase metal electrólito. Entre estos últimos, se pueden destacar el valor medio, el sesgo, la curtosis y el índice de picaduras, los cuales pueden reflejar cambios en el mecanismo de corrosión. Sobre todos estos parámetros destaca el uso de la resistencia de ruido. En este trabajo se ha llevado a cabo el tratamiento estadístico de los datos de ENM obtenidos cuando el aluminio es sometido a la acción a tres electrolitos diferentes, que provocan tres tipos distintos de corrosión: el agua destilada (pasividad), una disolución de cloruro de sodio (corrosión por picaduras) y una disolución de hidróxido de sodio (corrosión generalizada o uniforme).

Revista de Toxicología , 2003,
Abstract: Se presenta el caso de una mujer que ingirió 30 g de ácido valproico, entre otros psicofármacos, en una tentativa de suicidio. La intoxicación se caracterizó por el coma profundo, con hiperamoniemia (54 μmol/L) y una elevada concentración en sangre de ácido valproico (235 μg/mL). Aunque el curso clínico se complicó con una neumonía por aspiración, la paciente evolucionó favorablemente. Se discute el mecanismo por el que se produce la hiperamoniemia es ente tipo de intoxicación
Genomics, immune studies and diseases in bivalve aquaculture
A Romero,B Novoa,A Figueras
Invertebrate Survival Journal , 2012,
Abstract: Diseases are a critical bottleneck for the culture of bivalves causing important yield losses. Thestudy of bivalve diseases has relied on histological techniques and has focused on pathogenmorphology, the effect of external factors on the pathogens and infectivity, and on the development ofimmune and molecular diagnostic techniques. Recently, significant advances in the study of bivalvepathology have been reported; however, increased efforts using “omics tools” are required to explainkey physiological/immunological processes. Transcriptomic analysis in parallel with detailed functionalstudies of gene expression and cell biology in in vitro and in vivo experimental models are needed.Another important factor is the identification of “resistance traits” and a deeper understanding of theprocesses that contribute to the welfare of bivalves in culture. Additionally, the definition of "abnormalmortalities" is critical for managing and legislating bivalve aquaculture. The new technologies clearly“opens the door” for the directed manipulation of bivalves to improve the modern intensive aquaculturesystems. The future of bivalve research is exciting, and there is an obvious need to developmultidisciplinary international research studies involving research groups and growers organisations towork on shellfish pathology.

Open Journal of Internal Medicine (OJIM) , 2013, DOI: 10.4236/ojim.2013.34029
Abstract:

Medication reconciliation is priority in safety. Between 54% and 67% of hospitalized patients have at least one unintended discrepancies (UDs) between pharmacological treatment of a hospital inpatient and treatment that they were previously taking at home. Quasi-experimental pre-post study performed. The objective is to assess the impact of an intervention aimed at decreasing UDs between medication prescribed on admission and patient’s regular treatment. Patients who were hospitalised for more than 24 hours and were undergoing treatment prior to admission which involved taking three or more medicines were included. The number of patients included was 331 and 3781 medicines were reconciled. The incidence of UDs decreased significantly from 7.24% to 4.18%. Omission was the most common UD, with a significant decrease from 5.8% to 3.4%. Respect to clinical impact, we observed that error type C (error reached patient without causing harm) predominates, how- ever, experienced a statistically significant decrease from 5.3% to 2.4%.

USO DEL ANáLISIS DE IMáGENES EN EL DIAGNóSTICO DE LA "TRISTEZA DE LOS CíTRICOS" EN LIMONEROS (Citrus limon (L.) Burm.) DEL VALLE DE MALLARAUCO, CHILE

Abstract: with the objective of evaluating the use of image analysis in the detection of "citrus tristeza virus" on lemon trees (citrus limon (l.) burm.) and to calibrate a screening method for the disease, color aerial photographs of sectors with lemon orchards in the mallarauco valley; chile, and samples of healthy plants and plants with virus symptoms were taken. elisa tests for the virus and analysis of the spectral signatures of the sampled sites were performed. simple visual inspection of the photographs was enough to discriminate between areas with healthy and sick plants. the reflectivity of the three bands- blue, green and red - was higher in sick plants than in healthy plants. moreover, the discrimination between sectors of diseased plants was best on the red band. a significant correlation coefficient, 0.63, was found between sectors with ill plants and reflectance for the red band. on correlating the number of diseased plants with the area under curve of the spectral signatures a slightly superior correlation coefficient, 0.64 significant at 95%, was obtained. this implies that the technique not only can be used to discriminate between healthy and ill plants but also to evaluate the percentage of diseased plants in each sector of the orchard.
