Patent CA-2287781-A1 (CA)
Title: Methods for measuring cellular proliferation and destruction rates in vitro and in vivo
Inventor: HELLERSTEIN MARC
IPC: C12Q1/68
Filed: 1998-05-08
Abstract: The present invention relates to methods for measuring the proliferation and destruction rates of cells by measuring deoxyribonucleic acid (DNA) synthesis and/or destruction. In particular, the methods utilize non-radioactive stable isotope labels to endogenously label DNA synthesized through the de novo nucleotide synthesis pathway in a cell.  The amount of label incorporated in the DNA is measured as an indication of cellular proliferation. The decay of labelled DNA over time is measured as an indication of cellular destruction. Such methods do not involve radioactivity or potentially toxic metabolites, and are suitable for use both in vitro and in vivo. Therefore, the invention is useful for measuring cellular proliferation or cellular destruction rates in humans for the diagnosis, prevention, or management of a variety of disease conditions in which cellular proliferation or cellular destruction is involved. The invention also provides methods for measuring proliferation or destruction of T cells in a subject infected with human immunodeficiency virus (HIV) and methods of screening an agent for a capacity to induce or inhibit cellular proliferation or destruction. In addition, the invention provides methods for measuring cellular proliferation in a proliferating population which utilize both radioactive isotope labels and stable isotopes to endogenously label DNA through the de novo nucleotide synthesis pathway.

Title: Protective varnish for dentin
Inventor: LYNCH EDWARD
IPC: A61K6/884
Filed: 1998-09-08
Abstract: A protective varnish is provided for prophylactic treatment of exposed dentin. The varnish offers mechanical protection from wear and prevents hypersensitivity by blocking the dentin tubules. The varnish comprises a matrix of curable resins. These resins penetrate the dentin and after curing enforce it, making the dentin more resistant to abrasion. The varnish may also offer an antimicrobial effect. This effect can be achieved by the varnish containing a broad spectrum antimicrobial agent such as 2,4,4'-trichloro-2'-hydroxydiphenyl ether.
