Implementing the NDC theoretical model: a comparison of Italy and Sweden
No full textThe paper compares two European pension reforms of the 90’s, the Italian and the Swedish, both based on the so called Notional Defined Contribution scheme that merges the pay-as-you-go financial architecture with the award and indexation formulas typical of defined-contribution funded systems. The analysis moves from a theoretical framework allowing to better understand the Italian and the Swedish implementations of the NDC model. The comparative analysis shows the incongruities and fragility of the Italian reform as opposed to the coherence and rationality of the Swedish one
Productivity shocks, stabilization policies and the dynamics of net foreign assets
No full textIn this paper we investigate the role of macroeconomic stabilization policies for the international transmission of productivity shocks and their effects on the external sector. We develop a two-country stochastic Dynamic New-Keynesian “perpetual youth” model of the business cycle with incomplete international financial markets. Our OLG structure implies stationary net foreign asset dynamics and allows for a thorough analysis of the interaction of monetary policy with non-balanced budget fiscal policy. We derive the dynamic and cyclical properties of fiscal deficit feedback rules and their implications for net foreign assets dynamics. Our results imply that the degree of “fiscal discipline”, i.e. the extent to which the fiscal rule responds to debt dynamics, is crucial for the dynamics of net foreign assets. We show that under a counter-cyclical fiscal rule with low fiscal discipline temporary positive productivity shocks may result in substantial deteriorations of the Net Foreign Asset position in the medium run. This result crucially hinges on the interplay among nominal rigidities, non-balanced budget fiscal policy, and the wealth effects on consumption that are implied by our OLG structure
Inhibition of nitric oxide synthase prevents magnesium-free-induced epileptiform activity in guinea-pig olfactory cortex neurones in vitro.
No full textThe effects of N-nitro-L-arginine methyl ester (L-NAME), a nitric oxide (NO) synthase inhibitor, were examined on Mg2+-free-induced epileptiform activity, in guinea-pig piriform cortex slices in vitro. L-NAME (0.1-1 mM) had no effect on neuronal membrane properties or electrically-evoked postsynaptic potentials (PSPs). In contrast, during superfusion of the slices with Mg2+-free solution neurones exhibited spontaneous and stimulus-evoked epileptiform potentials that were suppressed in the presence of L-NAME (100 mu M) or the selective NMDA receptor antagonist DL-APV (100 mu M). The inhibitory effects induced by L-NAME were reversibly reduced by L-arginine (1 mM), but not D-arginine (1 mM), the latter drug not being a substrate for NO formation. It was concluded that L-NAME can suppress epileptiform activity induced by Mg2+-free exposure primarily through a decrease in presynaptic transmitter release, although additional actions on the NMDA-receptor complex were also considered
308 nm monochromatic excimer light in the treatment of psoriasis
No full textBackground: Various reports showed the efficacy of Narrow Band UVB (311-313 nm) and excimer laser (308 nm) in the treatment of psoriasis. Objective: To prove the efficacy of light produced by xenon-cloride excimer at 308 nm (Monochromatic Excimer Light, MEL) in the treatment of stable forms of localized plaque psoriasis. Patients and methods: This study was an open trial with 152 patients affected with stable mild to moderate plaque psoriasis (PASI score between 4 and 12) were treated with a weekly session of MEL A total number of 6-16 sessions was performed with a dose increase according to patient phototype and response. Results: 152 patients were enrolled in the study and 149 completed the protocol. Patients were followed up every two weeks, 57 patients for one-year and 92 patients for 6 months. After 4 months there was complete remission in 87 patients, partial remission in 37 and moderate improvement in 25 patients. Conclusions: These preliminary results suggest that MEL can be considered as a valid option for treatment of selected forms of localized plaque psoriasis
