Abstract: The invention relates to a device that comprises a memory circuit with memory cells that use floating gate storage transistors, which are conventionally called non-volatile memory cells. A particular embodiment relates to a teletext circuit. A teletext processing circuit comprising a decoder logic circuit and a memory circuit integrated together in an integrated circuit, the memory circuit comprising memory cells for storing teletext page data, the memory cells comprising floating gate storage transistors to store the teletext page data. The page data from memory is used to control the content of displayed teletext images.

Abstract: New bactericidal and/or bacteriostatic, thermostable peptides which are isolated from hemolymph of immune honeybees and which are distinct from lysozymes, attacins, cecropins, diptericins and magainins. The peptides feature at least the 10 C-terminal amino acids of the following peptide:H.sub.2 N-Gly-Asn-Asn-Arg-Pro-X-Tyr-Ile-Pro-Gln-Pro-Arg-Pro-Pro-His-Pro-Arg-Z-OHin whichX is a valyl or isoleucyl residue andZ is a leucyl or isoleucyl residue.
