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.

Abstract: Photosensitizer mixtures and method of treating cellulites by light illumination are presented. Photosensitizer is combined with cellular products, e.g. adipose cells, collagen, previously removed by liposuction. Concentrations used depend on treatment area, cellulite stage and whether cellulites are in depressed or elevated skin areas. The cosmetic treatment reduces/removes localized lipodystrophies, flaccidity, cellulite using localized laser, LED, etc emissions. Applied light energy destroys “fat” cells by a combination of chemical reactions primarily, and temperature, wherein cell walls break releasing cell fluid. Transmission devices guide radiation to the treatment site. One or more light sources like laser diodes or LEDs may be coupled into one or more optical fibers to increase the covered area and increase the amount of radiation in that area. Optical fibers can be introduced percutaneously or interstitially. Cell fluid in the treatment area is removed by a combination of techniques.

Abstract: A method for the treatment of myeloma and thymoma by administering a therapeutically effective dose of Mycobacterium indicus pranii with Cyclophosphamide. This disclosure generally relates to the field of cancer biology. More specifically, this disclosure relates to the immunotherapeutic treatment of myeloma and thymoma, using a combination of heat killed Mycobacterium indicus pranii and the widely administered chemotherapeutic drug, Cyclophosphamide.
