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.

Abstract: A method and apparatus or configuration generates light of a given polarization state (P). A polarization state-sensitive beam splitter is acted upon by light (L) at an input (E<SUB>1</SUB>), light (L<SUB>P</SUB>) of the given polarization state being output by the beam splitter ( 1 ) at a first beam splitter output (A<SUB>1</SUB>). Light (L<SUB>S</SUB>) with polarization state (S) that is perpendicular to the given state (P) is changed with respect to this state and also output. The light of the changed polarization state again acts upon the polarization state-sensitive beam splitter at the input (E<SUB>1</SUB>). The apparatus or configuration achieves this by having the optic input (E<SUB>3</SUB>) of a polarization state-changing structural element whose optic output (A<SUB>3</SUB>) is operationally connected to the optic input (E<SUB>1</SUB>) of the polarization state-sensitive beam splitter, operationally connected to the second optic output (A<SUB>2</SUB>).

Abstract: A data packet router enables a mobile communication device to access a WAN such as the Internet via a PC connected to the WAN. The router comprises bearer plug-in modules which each enable connection between the mobile communication device and the computer over a different bearer. The PC is therefore used as an internet access point for mobile communication devices which can use any conventional bearer to connect to the PC (USB, RS232, Bluetooth wireless etc.). Hence, a mobile telephone could gain web access using conventional WAP or, with the present invention, it could also be connected to a PC using a convenient bearer and hence gain access to the internet via the PC. Because the router uses bearer plug-in modules, it is possible to write new bearer modules as and when new bearers are developed and to readily add them to upgrade existing implementations. This is valuable since new connectivity standards (and enhancements to old standards) are continually under development.
