Abstract: Polyamide compositions containing guanidinyl radicals, including tetramethylguanidinyl radicals, are described. These polyamides are useful for medical applications, for example, for treating human papilloma virus infections.

Abstract: The present invention relates to polyamide compositions and therapies for treating cells infected with human papilloma virus (HPV).

Abstract: A method is provided for decontaminating a surface that is susceptible to contamination by a contaminant by applying to the surface a coating which produces a decontaminating agent for the contaminant in response to a signal, connecting the electroactive coating to a source of a signal, and when the surface is contaminated, applying the signal to the electroactive coating, thereby producing one or more decontaminating agents which neutralize or destroy the contaminant. Coatings for practicing the method and articles that have been protected by the novel coatings are also provided.

Abstract: Sperm in semen are sorted by fluorescence-activated cell sorting into gender-enriched populations enriched in X-chromosome or Y-chromosome bearing sperm by use of a fluorescent quantitative DNA-binding vital stain.

Abstract: The present invention is directed to the means by which to alter the binding affinity and/or specificity of a compound with a sequence of DNA in the minor groove of a double-strand thereof. More particularly, the present invention is directed to a synthetic and/or non-naturally occurring compound (e.g., an analog of a polyamide oligomer or polymer) which contains at least one hydrogen bond donor moiety and at least one hydrogen bond acceptor moiety, wherein the latter moiety or “building block” has a fused, bicyclic structure which is heteroaromatic, said structure having a heteroatom therein which acts as a hydrogen bond acceptor to bind guanine in the minor groove of the dsDNA sequence, and which is incapable of forming a tautomer. In one particular embodiment of the synthetic and/or non-naturally occurring compound, the fused, bicyclic structure occupies an initial or first terminal position within the compound.
