BACKGROUND: Several therapies are available for psoriasis, including in some countries oral fumaric acid derivatives (FADs). Even if FADs are not available in the Italian market, they can be prescribed and reimbursed by the National Health Service, on request from the treating physician, when considered as a valuable option in selected patient.METHODS: We performed a retrospective analysis of the

A monochromator has been developed for coronary angiography, comprising a single bent crystal of silicon in Laue transmission geometry. K spectra of laser irradiated solid tin and tantalum (Z=50 and 73, respectively) targets were measured. The high resolution crystal spectrometer resolve the Sn and Ta K alpha doublets, allowing in a proof-of-principle experiment the absolute K alpha photon numbers

Mercury concentrations in air and in condensed steam coming from fumarolic activity at the Solfatara crater (Phlegraean Fields - Italy) were determined. In the condensed steam, mercury was found mainly associated as Hg-S complexes and showed a flux in the range from 0.9 to 4.5 g day(-1). Using the point monitor technique, high values (up to 690 ng m(-3)) of atmospheric mercury levels were observed

The photoion excitation spectra of (NO)-N-14 and (NO)-N-15 have been studied in the 105-112 Mn excitation region using high-order harmonic laser spectroscopy. Utilizing the small bandwidth offered by this technique, the natural widths of prominent lines in this region have been measured. These lines originate from interactions between high-lying Rydberg levels converging to the NO+ electronic grou
