COMPARISON BETWEEN USES OF TOPICAL TACROLIMUS AND TRIAMCINOLONE OINTMENT FOR THE TREATMENT OF ORAL LICHEN PLANUS.

Comparison between uses of topical tacrolimus and triamcinolone ointment for the treatment of oral lichen planus.

Background: Lichen planus is a chronic mucocutaneous disease with primary or secondary involve- ment of the oral mucosa.In particular in case of erosive lichen planus most of the patients experience no long term symptoms relief of conventional topical treatment such as corticosteroid ointment.Topical tacrolimus applications to mucosal lesions seem

Advances in Mass Spectrometers for Flyby Space Missions for the Analysis of Biosignatures and Other Complex Molecules

Spacecraft flybys provide access to the chemical composition of the gaseous envelope of the planetary object.Typical relative encounter velocities range from km/s to tens of km/s in flybys.For speeds exceeding about 5 km/s, modern mass spectrometers analyzing the rapidly encountering gas suffer from intrinsic hypervelocity impact-induced fragmentat
