Patent IL-192467-B (IL)
Title: Rna sequence-specific mediators of rna interference
IPC: A61K31/7105
Filed: 2008-06-26
Abstract: The present invention relates to a Drosophila in vitro system which was used to demonstrate that dsRNA is processed to RNA segments 21-23 nucleotides (nt) in length. Furthermore, when these 21-23 nt fragments are purified and added back to Drosophila extracts, they mediate RNA interference in the absence of long dsRNA. Thus, these 21-23 nt fragments are the sequence-specific mediators of RNA degradation. A molecular signal, which may be their specific length, must be present in these 21-23 nt fragments to recruit cellular factors involved in RNAi. This present invention encompasses these 21-23 nt fragments and their use for specifically inactivating gene function.; The use of these fragments (or chemically synthesized oligonucleotides of the same or similar nature) enables the targeting of specific mRNAs for degradation in mammalian cells, where the use of long dsRNAs to elicit RNAi is usually not practical, presumably because of the deleterious effects of the interferon response. This specific targeting of a particular gene function is useful in functional genomic and therapeutic applications.

The resulting wheel has light weight and high mechanical breakage strength, enabling high peripheral speed.
Patent IN-191872-B (IN)
Inventor: SANDMEIER HERMANN
IPC: B05D7/24
Filed: 1997-01-14
Abstract: Adhesive is applied by an arrangement of a chamber (23) containing the adhesive (24), a roller (1) partly immersed in the adhesive and an application roller (2) applying adhesive to a workpiece passing by the roller. In the absence of a workpiece, the axle of the application roller is swivelled away from the gripping device by an eccentric axle (36) which does not coincide with the axis of rotation of the roller. The axles of the application roller of that of the adhesive roller are movable so that the distance between the two rollers remains the same. Preferably the adhesive roller and a sealing roller (25) cover the front of the adhesive chamber, the former defining a gap with a vertical wall of the chamber for return of non-applied adhesive and the latter being sealed against the other vertical wall of the chamber and forming a gap with the adhesive roller for adhesive to pass through.
