Medidas compensatorias en el MERCOSUR
2011
El Mercosur tiene establecido un procedimiento obligatorio de solución de controversias comerciales entre los Estados miembros. Los laudos arbitrales que se dicten son de obligado cumplimiento. Para el caso en el que un Estado miembro no cumpla un laudo arbitral, el Estado afectado le puede imponer unilateralmente medidas compensatorias para garantizar el cumplimiento del laudo. Al estudio de esta posibilidad se dedica este trabajo.
Computational analysis of lung deformation after murine pneumonectomy. [corrected].
2012
In many mammalian species, the removal of one lung (pneumonectomy) is associated with the compensatory growth of the remaining lung. To investigate the hypothesis that parenchymal deformation may trigger lung regeneration, we used microCT scanning to create 3-dimensional finite element geometric models of the murine lung pre- and post-pneumonectomy (24 hours). The structural correspondence between models was established using anatomic landmarks and an iterative computational algorithm. When compared with the pre-pneumonectomy lung, the post-pneumonectomy models demonstrated significant translation and rotation of the cardiac lobe into the post-pneumonectomy pleural space. 2-dimensional maps…
Redox signaling in acute pancreatitis
2015
Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On th…
Sprouting and intussusceptive angiogenesis in postpneumonectomy lung growth: mechanisms of alveolar neovascularization
2013
In most rodents and some other mammals, the removal of one lung results in compensatory growth associated with dramatic angiogenesis and complete restoration of lung capacity. One pivotal mechanism in neoalveolarization is neovascularization, because without angiogenesis new alveoli can not be formed. The aim of this study is to image and analyze three-dimensionally the different patterns of neovascularization seen following pneumonectomy in mice on a sub-micron-scale. C57/BL6 mice underwent a left-sided pneumonectomy. Lungs were harvested at various timepoints after pneumonectomy. Volume analysis by microCT revealed a striking increase of 143 percent in the cardiac lobe 14 days after pneum…
Mapping cyclic stretch in the postpneumonectomy murine lung
2013
In many mammalian species, the removal of one lung [pneumonectomy (PNX)] is associated with the compensatory growth of the remaining lung. To investigate the hypothesis that parenchymal deformation may trigger lung regeneration, we used respiratory-gated micro-computed tomography scanning to create three-dimensional finite-element geometric models of the murine cardiac lobe with cyclic breathing. Models were constructed of respiratory-gated micro-computed tomography scans pre-PNX and 24 h post-PNX. The computational models demonstrated that the maximum stretch ratio map was patchy and heterogeneous, particularly in subpleural, juxta-diaphragmatic, and cephalad regions of the lobe. In these…
Regulatory Network Of Angiogenesis Gene Expression During Post-Pneumonectomy Compensatory Growth

Invasive and native populations of common ragweed exhibit strong tolerance to foliar damage.
2013
8 pages; International audience; Tolerance and resistance are defence strategies evolved by plants to cope with damage due to herbivores. The introduction of exotic species to a new biogeographical range may alter the plant herbivore interactions and induce selection pressures for new plant defence strategies with a modified resource allocation. To detect evolution in tolerance to herbivory in common ragweed, we compared 3 native (North America) and 3 introduced (France) populations, grown in a common garden environment. We explored the effect of leaf herbivory on plant vegetative and reproductive traits. Plants were defoliated by hand, simulating different degrees of insect grazing by remo…
A BoD Composite Indicator to Measure the Italian “Sole 24 Ore” Quality of Life
2023
The measure of Quality of Life (QoL) is still a topic widely discussed in literature. In Italy, the newspaper “Il Sole 24 Ore” publishes a famous ranking that highlights strong disparities among provinces. In this paper, “Il Sole 24 Ore” and BoD-DEA methods are compared in order to show how different types of normaliza- tion and aggregation significantly influence the results making these rankings very fragile and questionable.
Facing natural disasters through the endorsement of authoritarian attitudes
2020
Abstract We analyzed the relations between exposure to news describing a natural disaster and right-wing authoritarianism (RWA) with 241 Italian adults, surveyed twice, before and after a severe earthquake. Our results were compatible with the idea that the exposure to earthquake news led to an increase in RWA among people who had low, but not among who had relatively high, authoritarian levels before the event. We discuss the findings in terms of compensatory control, and highlight strengths and limitations of the study.
Societal Threat to Safety, Compensatory Control, and Right-Wing Authoritarianism
2014
We analyzed directly and indirectly the relationships between societal threat to safety, perceived control, and the increase in right-wing authoritarianism (RWA) in two studies. In Study 1 (national sample of the Italian population, N=1,169), we performed a longitudinal analysis structured into three waves (January 2003, September 2004, and January 2005). A moderated regression analysis showed that RWA increased from 2003 to 2005 as a function of perceived societal threat to safety more among low- than among high RWA scorers. In experimental Study 2 (Italian university students, N=131) a moderated mediation model showed loss of perceived control to mediate the relation between societal thre…
