Abstract: The invention provides a hair shaping composition suitable for topical application to hair, the composition having a pH of 4 or less and comprising, in an aqueous continuous phase: (i) at least 0.5% (by weight based on the total weight of the composition) of one or more polyhydroxy acid lactones; (ii) at least 0.5% (by weight based on the total weight of the composition) of one or more aliphatic di- or tricarboxylic acids, and (iii) at least 0.1% (by weight based on the total weight of the composition) of glyoxylic acid or a salt or hydrate thereof.

Abstract: The present invention provides a purified preparation containing a polynucleic acid encoding at least one polypeptide selected from the group consisting of proteins encoded by one or more open reading frames (ORF's) of an Iowa strain of porcine reproductive and respiratory syndrome virus (PRRSV), proteins at least 80% but less than 100% homologous with those encoded by one or more of ORF 2, ORF 3, ORF 4 and ORF 5 of an Iowa strain of PRRSV, proteins at least 97% but less than 100% homologous with proteins encoded by one or both of ORF 6 and ORF 7 of an Iowa strain of PRRSV, antigenic regions of such proteins which are at least 5 amino acids in length and which effectively stimulate immunological protection in a porcine host against a subsequent challenge with a PRRSV isolate, and combinations thereof, in which amino acids non-essential for antigenicity may be conservatively substituted.

Abstract: The present invention provides an isolated DNA sequence encoding, for example, at least one polypeptide selected from the group consisting of proteins encoded by one or more open reading frames (ORF's) of an Iowa strain of porcine reproductive and respiratory syndrome virus (PRRSV), specifically ISU-12, and the polypeptides encoded by the isolated DNA sequences. The present invention also concerns a vaccine comprising an effective amount of such a protein; methods of producing antibodies which specifically bind to such a protein; and methods of protecting a pig against a PRRSV, and treating a pig infected by a PRRSV.
