Renal effects of vasodilators in acute heart failure  [PDF]
Mattia A. E. Valente, Adriaan A. Voors
World Journal of Cardiovascular Diseases (WJCD) , 2013, DOI: 10.4236/wjcd.2013.32A002
Abstract:

Vasodilator therapy is common in acute heart failure (AHF) patients, although evidence for morbidity and mortality benefits is limited for many of these drugs. AHF is frequently accompanied by renal dysfunction, which is a strong, independent predictor for poor prognosis. Several hemodynamic and neurohormonal effects of vasodilators—including preload and afterload reduction, activation or inhibition of neurohormonal and inflammatory cascades—have the potential to modulate cardiorenal interaction and impact renal function. However, the effect of vasodilators on renal function in acute heart failure is often poorly described. In this review, we provide an overview of the known cardiorenal effects of traditional and novel vasodilators in patients with acute heart failure.

Volem viure: nacionalismo occitano en el sur francés
Contreras Romero, Valente A.;
Política y cultura , 2006,
Abstract: this paper aims to show the peculiarity of the occitan nationalist movement that arose in southern france during the 1970′s. the paper is divided in two parts: the first one explains the rise of the occitan movement, which arose from three social resurgence movements that were closely linked to economic globalization and technological modernization; it also analyzes how the locals went about building their national identity and which were the causes that did not allow for the movement to consolidate itself as a sound nationalistic movement. the second part describes the current situation of the occitan political movement and its effects on french society.
Transforma es no estado capitalista: refletindo e refratando transforma es na quest o social
Heidrich, Andréa Valente
Textos & Contextos (Porto Alegre) , 2006,
Abstract: Neste artigo, pretende-se fazer uma revis o na literatura do Servi o Social relativamente à quest o social. Busca-se, ainda, retratar o debate corrente sobre a existência de uma “nova quest o social”, derivada das transforma es pelas quais a sociedade capitalista vem atravessando desde os anos de 1970. Procura-se demonstrar que, em que pese estas transforma es, a gênese da quest o social continua sendo a mesma: a contradi o inerente ao sistema capitalista e a explora o de uma classe social sobre a outra.
Volem viure: nacionalismo occitano en el sur francés
Valente A. Contreras Romero
Política y cultura , 2006,
Abstract: El presente trabajo intenta mostrar la particularidad del movimiento nacionalista occitano que surgió en el sur de Francia durante los a os setenta. El trabajo está compuesto por dos partes: en la primera explicaremos el surgimiento del movimiento occitano a partir de tres pronunciamientos de reivindicación social estrechamente ligados con la globalización económica y la modernización tecnológica; analizaremos cómo se fue construyendo su identidad nacional y cuáles fueron las causas que no permitieron que cuajara como un levantamiento nacionalista fuerte; en la segunda se expondrá el contexto actual del movimiento político occitano y su efecto en la sociedad francesa.
El riesgo asociado a la banca comercial y universal venezolana
Soto,Antonio; Valente,María;
Revista Venezolana de Gerencia , 2007,
Abstract: this article focuses on analyzing, from a theoretical-practical perspective, risk behavior related to credit, adjustment term and interest rates in commercial and universal venezuelan banking as a whole for the triennium 1998-2000, years in which economic policies experienced behaviors of a different sort. using descriptive-observational research, results revealed that this important segment of the financial sector demonstrated an exposure to adjustment term risk by obtaining liabilities consisting of short term deposits related to holding assets in medium and long-term loans. likewise, conclusions were that good performance of the economic environment reduces the possibilities that the financial system faces credit risk, given the better financial position of the economic agents selling funds that can be loaned. also, interest rate risk was not present in the venezuelan banking system during the period under study, given the disposition by monetary policies to try and reduce the differential between active and passive interest rates, without allowing this differential to become negative for this important sector of the venezuelan financial system.
El riesgo asociado a la banca comercial y universal venezolana
Antonio Soto,María Valente
Revista Venezolana de Gerencia , 2007,
Abstract: El presente artículo se centra en analizar desde una perspectiva teórico-práctica el comportamiento del riesgo crediticio, calce de plazos y tasas de interés en el conjunto de la banca comercial y universal venezolana para el trienio 1998-2000, a os éstos donde las políticas económicas experimentaron comportamientos de diferente corte. A través de una investigación de tipo descriptivo-observacional, los resultados revelan que este importante segmento del sector financiero presentó una exposición al riesgo de calce de plazos al obtener pasivos conformados por depósitos a corto plazo en relación a la tenencia de activos en préstamos a mediano y largo plazo. Igualmente se concluye, el buen desempe o del entorno económico reduce las posibilidades que el sistema financiero se enfrente al riesgo crediticio, dada la mejor posición financiera de los agentes económicos demandantes de fondos prestables. Por su parte, el riesgo de tasas de interés no estuvo presente en el sistema bancario venezolano durante el periodo de estudio, dada la disposición por parte de las políticas monetarias en tratar de bajar el diferencial entre las tasas de interés activas y pasivas, sin que este diferencial se tornara negativo para este importante sector del sistema financiero venezolano.
Prediction in the Hypothesis-Rich Regime
A. X. C. N. Valente
Quantitative Biology , 2010,
Abstract: We describe the fundamental difference between the nature of problems in traditional physics and that of many problems arising today in systems biology and other complex settings. The difference hinges on the much larger number of a priori plausible alternative laws for explaining the phenomena at hand in the latter case. An approach and a mathematical framework for prediction in this hypothesis-rich regime are introduced.
Homogenization of Portuguese long-term temperature data series: Lisbon, Coimbra and Porto
A. L. Morozova,M. A. Valente
Earth System Science Data (ESSD) & Discussions (ESSDD) , 2012, DOI: 10.5194/essd-4-187-2012
Abstract: Three long-term temperature data series measured in Portugal were studied to detect and correct non-climatic homogeneity breaks and are now available for future studies of climate variability. Series of monthly minimum (Tmin) and maximum (Tmax) temperatures measured in the three Portuguese meteorological stations of Lisbon (from 1856 to 2008), Coimbra (from 1865 to 2005) and Porto (from 1888 to 2001) were studied to detect and correct non-climatic breaks. These series, together with monthly series of average temperature (Taver) and temperature range (DTR) derived from them, were tested in order to detect breaks, using firstly metadata, secondly a visual analysis, and thirdly four widely used homogeneity tests: von Neumann ratio test, Buishand test, standard normal homogeneity test, and Pettitt test. The homogeneity tests were used in absolute (using temperature series themselves) and relative (using sea-surface temperature anomalies series obtained from HadISST2.0.0.0 close to the Portuguese coast or already corrected temperature series as reference series) modes. We considered the Tmin, Tmax and DTR series as most informative for the detection of breaks due to the fact that Tmin and Tmax could respond differently to changes in position of a thermometer or other changes in the instrument's environment; Taver series have been used mainly as control. The homogeneity tests showed strong inhomogeneity of the original data series, which could have both internal climatic and non-climatic origins. Breaks that were identified by the last three mentioned homogeneity tests were compared with available metadata containing data such as instrument changes, changes in station location and environment, observation procedures, etc. Significant breaks (significance 95% or more) that coincided with known dates of instrumental changes were corrected using standard procedures. It was also noted that some significant breaks, which could not be connected to known dates of any changes in the park of instruments or stations location and environment, were probably caused by large volcanic eruptions. The corrected series were again tested for homogeneity; the corrected series were considered free of non-climatic breaks when the tests of most of monthly series showed no significant (significance 95% or more) breaks that coincide with dates of known instrument changes. Corrected series are now available within the framework of ERA-CLIM FP7 project for future studies of climate variability (doi:10.1594/PANGAEA.785377).
