Abstract: The present invention relates to the use of compound 1-[4-methylthiophenyl]-3-[3,5-dimethyl-4-carboxydimethyl-methyloxyphenyl]prop-2-en-1-one for treating fibrotic diseases and cancers.

Abstract: A surface acoustic electric wave device of the type comprising, over a large face of a planar piezo-electric substrate, a first row of parallel conductive fingers having an individual geometry chosen and distributed according to a chosen distribution arrangement along this row, a second row of parallel conductive fingers having an individual geometry chosen and distributed according to a chosen distribution arrangement along this row, the second row being interspaced from the first so as to allow a propagation of surface acoustic waves between the fingers of the first row and those of the second, which imparts to the device spectral and/or temporal characteristics defined by the acoustic propagation and the frequency selectivity due to the geometry of the fingers.

Abstract: The invention concerns electric/acoustic input transducers and acoustic/electric output transducers, in particular for a surface wave device, of the type comprising on a large face of a planar piezoelectric substrate: (i) two conductive input zones or output zones separated by a substrate band over which there extend respective parallel fingers which are interlaced according to a pattern chosen to form a row of fingers along this band, the general direction of the band being inclined to the direction of the fingers; and (ii) electric input means for applying high frequency signals between the zones so as to form sources of surface acoustic waves on the substrate or output means for extracting the signals detected by the device.
