IPC: G01N33/68
Filed: 2001-02-08
Abstract: The invention provides methods for diagnosing the efficacy of a patient to xenotypic antibody therapy which include (1) measuring the level of an antibody produced by a patient that specifically binds to a xenotypic antibody after administration of the xenotypic antibody to the patient; (2) measuring the level of an anti-idiotype antibody produced by a patient that specifically binds to a xenotypic antibody after administration of the xenotypic antibody to the patient; (3) measuring the level of an antibody produced by a patient that specifically binds to a target antigen of a xenotypic antibody after administration of a xenotypic antibody to the patient; and (4) measuring the level of a T cell response produced by a patient to a target antigen of the xenotypic antibody after administration of a xenotypic antibody to the patient. In the methods of the invention, an increase in the level of antibody or T cell response produced by the patient after the administration of the xenotypic antibody relative to the level antibody or T cell response produced by the patient prior to the administration of the xenotypic antibody is indicative of a favorable diagnosis of efficacy.

Title: Nanoscopic hair care products
Inventor: LINFORD MATTHEW R
IPC: A61K8/44
Filed: 2001-04-13
Abstract: The present invention is directed to a hair treatment preparation comprising  a payload in an intimate relationship to a polymeric nanostructure, the polymeric nanostructure being reactive to hair or capable of being immobiliz ed onto or in hair. The nanoscopic nature of the entities being engineered ensures three distinct characteristics. First, the imparted attribute can be  either nearly permanent or semi-permanent, depending on the attachment chemistry. In the semi-permanent version, the intended effect can be controllably erased by removal of the nanostructure by simple chemical or physical means. Second, the nanoscopic entities are invisibly small. Their presence does not deteriorate the hand or feel of the hair. Third, the nano- technology approach is infinitely flexible and adaptable. It can be coupled with many existing dyes, colorants, UV absorbers, fragrances, softening agen ts and the like for hair treatment. Methods for treating hair with the hair treatment preparations of the invention are also encompassed.
