Association between MICA Gene Variants and the Risk of Hepatitis C Virus-Induced Hepatocellular Cancer in a Sicilian Population Sample
2018
There are currently no biomarkers that predict hepatocellular carcinoma (HCC) risk in patients with hepatitis C virus (HCV)-related cirrhosis. We investigated the relationships among major histocompatibility complex (MHC) class I chain-related gene A (MICA) polymorphisms, plasma levels of soluble MICA (sMICA), and HCC risk in patients with HCV-related HCC. One hundred fifty-four HCV-related HCC patients, 93 HCV-related liver cirrhosis (LC) cases, and 244 healthy controls, all sampled from the native Sicilian population, were genotyped using the KASP™ single-nucleotide polymorphism genotyping method. The MICA rs2596542 polymorphism showed that the G/G genotype was significantly more frequent…
Predicting the bioaccumulation of polyaromatic hydrocarbons and polychlorinated biphenyls in benthic animals in sediments
2016
There were two main objectives in this study. The first was to compare the accuracy of different prediction methods for the chemical concentrations of polyaromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in the organism, based on the measured chemical concentrations existing in sediment dry matter or pore water. The predicted tissue concentrations were compared to the measured ones after 28-day laboratory test using oligochaeta worms (Lumbriculus variegatus). The second objective was to compare the bioaccumulation of PAHs and PCBs in the laboratory test with the in situ bioaccumulation of these compounds. Using the traditional organic carbon-water partitioning model, tissue…
The Hamburg/ESO R-process Enhanced Star survey (HERES):XI. The highly r-process-enhanced star CS 29497-004
2017
We report an abundance analysis for the highly r-process-enhanced (r-II) star CS 29497-004, a very metal-poor giant with Teff = 5013K and [Fe/H]=-2.85, whose nature was initially discovered in the course of the HERES project. Our analysis is based on high signal-to-noise, high-resolution (R~75000) VLT/UVES spectra and MARCS model atmospheres under the assumption of local thermodynamic equilibrium, and obtains abundance measurements for a total of 46 elements, 31 of which are neutron-capture elements. As is the case for the other 25 r-II stars currently known, the heavy-element abundance pattern of CS 29497-004 well-matches a scaled Solar System second peak r-process-element abundance patter…
Monetary Plurality in Economic Theory
2018
The objective of this article is to identify the monetary plurality in economic theory. We will try to throw light on the way in which theories are attracted towards both unicity and plurality, and more specifically by unification and diversification of money. It should also be noted, in this respect, that the economics of money has undergone considerable development since the 1970s. A survey of the diverse theories, whether mainstream or not, static or dynamic, holistic or individualistic, will reveal the surprising amount of attention devoted to the problem of monetary unicity and/or plurality. We base our presentation on two lines of thought: -The first of these lines concerns a situatio…
ESTIMATION OF AN EXTENDED SAM WITH HOUSEHOLD PRODUCTION FOR SPAIN 1995
2005
This paper implements the conceptual framework sketched by Pyatt (1990) to construct an extended Social Accounting Matrix for Spain in 1995 (ESAM-95) to consider, in addition to the market economy, the production of services provided by households through unpaid work. In doing so, the ESAM-95 integrates the accounts related to market activities (ESA accounts) with non-market activities (non-ESA accounts) in a consistent way. Additional classifications are introduced in both ESA and non-ESA accounts in order to disaggregate the institutional accounts by household type and those of production factors by educational level and gender. The extended SAM is useful to calibrate CGE models in which …
Spain in the euro: a general equilibrium analysis
2010
Bayesian dynamic stochastic general equilibrium (DSGE) models combine microeconomic behavioural foundations with a full-system Bayesian likelihood estimation approach using key macro-economic variables. Because of the usefulness of this class ofmodels for addressing questions regarding the impact and consequences of alternative monetary policies they are nowadays widely used for forecasting and policy analysis at central banks and other institutions. In this paper we provide a brief description of the two main aggregate euro area models at the ECB. Both models share a common core but their detailed specification differs reflecting their specific focus and use. The New Area Wide Model (NAWM)…
The shadow price of foreign exchange with minimum wages
2001
Abstract This note derives the shadow price of foreign exchange in a small open economy with minimum wage unemployment under tariffs, quotas and voluntary export restraints. The analysis is conducted in a dual general equilibrium framework with many goods and factors.
Fiscal sustainability in the EU: From the short-term risk to the long-term challenge
2015
Abstract The paper analyses fiscal sustainability of public debt using a dynamic computable general equilibrium model. First, we identify the short-term risk for fiscal stress at country level; second, we investigate the assumption of convergence towards the government debt threshold (medium-term challenge); and, third, the requirement that debt projections do not show unsustainable trends (long-term challenge). The empirical implementation includes 18 EU Member States. Our findings show that the constant tax rate that stabilizes the public debt converges to 50 percentage of GDP for all the sample countries and tax revenues are the main driving forces for fiscal sustainability. Also our fin…
Fiscal Devaluations in EMU
2013
2013SummaryWe use a small open economy general equilibrium model to analyse the effects of a fiscal devalua-tion in an EMU country. The model has been calibrated for the Spanish economy, which is a goodexample of the advantages of a change in the tax mix given that its tax system shows a positive biasin the ratio of social security contributions over consumption taxes. The preliminary empirical evi-dence for European countries shows that this bias was negatively correlated with the current accountbalance in the expansionary years leading up to the 2009 crisis, a period when many EMU membersaccumulated large external imbalances. Our simulation results point to significant positive effects of…
