Title: Antagonists of human gamma interferon
Inventor: SEELIG GAIL F
IPC: C07K16/00
Filed: 1991-09-25
Abstract: Novel synthetic polypeptides having amino acid sequences corresponding to the sequence of one or more specific regions of human gamma interferon are provided by this invention. These polypeptides specifically inhibit the binding of human gamma interferon to cellular receptors and the biological activity of such interferon.  Antibody antagonists of the binding of human gamma interferon to cellular receptors based upon the use of the polypeptides as antigens are also provided. Some of these antagonists bind to specific regions of gamma interferon which are believed to be involved in interactions between the interferon and its receptors. Other antibody antagonists are anti-idiotypic antibodies which appear to compete directly with gamma interferon for binding to the cellular receptors. Also provided are methods for the use of the polypeptides and antibodies as inhibitors of the binding of gamma interferon to its cellular receptors.

Abstract: A disposable absorbent article, such as a sanitary napkin, is disclosed that has components which may separate in the Z-direction with relation to other components of the article when the absorbent article is worn.  The sanitary napkin of the present invention comprises a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core positioned between the topsheet and the backsheet, and a liquid pervious spacing structure for moving the topsheet away from the core.  The spacing structure is generally positioned between the topsheet and the core.  The spacing structure has a longitudinal centerline, and opposed lateral sides which may move inwardly toward the longitudinal centerline when the spacing is compressed from the sides.  This results in at least a portion of the spacing structure moving the topsheet apart from the absorbent core.  In an alternative embodiment, the sanitary napkin of the present invention also has an absorbent core which separates from the backsheet of the sanitary napkin.

Title: Cell lines for assaying human interchromosomal recombination
Inventor: BENJAMIN MARK B
IPC: C12Q1/68
Filed: 1992-07-30
Abstract: Cell lines useful for analysis of human homologous interchromosomal recombination are described. The cell lines carry endogenous mutant alleles of a selectable gene and can regenerate a selectable phenotype through homologous genetic recombination but not by large deletion of nucleotides or by chromosome loss. Assays using the cell lines permit quantitative and qualitative analysis of recombination events which occur between human chromosomes in somatic cells in culture. The assay relies on normal genes in their normal chromosomal site. The assays can be used to test for environmental agents which induce homologous recombination in human cells.
