    Abstract: A punch press tool for stamping successive multicharacter impressions into a workpiece such as a piece of steel, sheet metal, or other workpiece, includes a guide body in which a stamp driver is slidably mounted for being driven downwardly toward the workpiece by a punch press ram which is a standard part of a high speed commercial punch press. A multicharacter marking stamp is supported at the lower end of the stamp driver for reciprocal movement therewith. The marking stamp includes multicharacter wheels that are rotated automatically during operation for advancing characters in sequence responsive to the movement of a character advancing arm. At least one character stamp operating lever is operatively associated with the punch press tool for articulation responsive to motion imparted to the tool by the ram. The lever has an operating element that is operatively associated with the character advancing arm of the multicharacter stamp for indexing the arm to enable successive characters thereof to be placed in an operating position responsive to a stroke of the punch press ram.

    Abstract: Fluorous-tagged oligonucleotide reagents and an oligonucleotide purification methodology making use thereof, the method comprising: Synthesizing oligonucleotides using oligonucleotide reagents each bearing at least one fluorous group to yield a mixture of synthesis products and reagents, the mixture including at least one target synthesized oligonucleotide bearing at least one fluorous group; passing the mixture through a separation medium having an affinity for the at least one fluorous group so that the target synthesized oligonucleotide bearing at least one fluorous group is adsorbed by the separation medium; washing the separation medium with at least a first solvent to selectively dissociate therefrom substantially all synthesis products and reagents of the heterogenous mixture other than the at least one target synthesized oligonucleotide bearing at least one fluorous group; and subsequently dissociating the at least one synthesized oligonucleotide from the separation medium, with or without the fluorous group.

    Abstract: The invention provides methods and compositions for reducing the number of cancer stem cells in a mixed population of differentiated cells (for example, cancer cells) and cancer stem cells. The cancer stem cells, if present, can be more resistant to traditional drug-based therapies and can provide a source for new, differentiated cancer cells associated with the development of drug-resistance and more aggressive phenotypes. When combined with traditional cancer therapies, for example, drug-based therapies, the methods and compositions of the invention provide a more effective way for treating cancer and can provide a model system for developing new cancer therapies and new treatment modalities.
