    Drug prescription in Italy (1996)
    Springer
    European journal of clinical pharmacology 49 (1996), S. 429-430 
    Details
    ISSN: 1432-1041
    Keywords: Key words Drug expenditure; rational prescribing ; Italy

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Abstract Drug use in Italy in the period 1983–1991 has been analysed. The twenty most used substances accounted for about 20% of the sold packages. The effect of marketing of new drugs is worth noting: new and more expensive drugs are preferred even when effective, safe and less expensive alternatives are available. Prescribers have to face a highly dynamic pharmaceutical market in which 30% of substances (among the 300 most sold) changes every five years. Other than a more rational formulary, independent information and continuing education have to be considered as tools to improve a more rational prescribing.

    Preparation and Characterization of Fullerenes Containing Sol-Gel Glass (1997)
    Springer
    Journal of sol gel science and technology 8 (1997), S. 609-613 
    Details
    ISSN: 1573-4846
    Keywords: hybrid material ; fullerene ; optical materials ; optical limiting

    Topics: Chemistry and Pharmacology
    Notes: Abstract Transparent materials containing C60 are interesting because of their optical limiting properties. Fullerenes can be incorporated in sol-gel matrices, but their poor solubility in the solvents commonly used in the process and their tendency to form clusters constitutes the main experimental problem. For this reason we have synthesized C60 derivatives with high solubility and having reactive groups that could covalently bond to the inorganic network. By this way and by an optimization of the sol-gel preparation procedure, transparent films and bulks were obtained. Good optical limiting performances were demonstrated by experimental measurements.
