摘要:
Traditional methods for measuring the phosphorylation state of cellular proteins have relied on .sup.32 P-orthophosphate labeling of cells in culture. The problems associated with radioactive isotopes have therefor prohibited phosphorylation studies on whole animals and humans. The present invention provides a unique technique that allows quantitative attachment of probes (e.g. fluorophors or biotin) to phospho-proteins and peptides by activating phospho-amino acids. the phosphorylation state of cellular proteins derived from human tissues can now be measured. This method can be used for early detection of cancer and diabetes and also for the identification of pharmaceutical agents.

A stator assembly for use in a superconducting generator operated at frequencies up to 10 Hz is disclosed. The stator assembly includes a ferromagnetic stator winding support having a plurality of teeth defining slots, the slots configured to receive and support stator windings. The stator winding support is formed so that the ratio of the sum of the widths of the slots to the sum of the widths of the teeth and slots is in the range of 0.65 to 0.90.

摘要:
An antibody is provided which binds to active GGT, and can identify tissues which express GGT on their surface. Many solid tumors express GGT on their surface. Individuals identified with such tumors may be treated with inactivated prodrugs of chemotherapeutic agents at local dosage levels substantially above the maximum dosage levels currently permitted due to side effect limitations. The prodrugs are comprised of chemotherapeutic agents rendered inactive by the attachment of a gamma-glutamyl group thereto. The gamma-glutamyl group is cleaved by GGT on the surface of solid tumor cells expressing GGT, and thus active only locally against the tumor. Side effects are suppressed. The antibody is used to identify solid tumors that are candidates for this treatment, as well as to identify tissues which express GGT and which must therefore be the basis of selection criteria of various available chemotherapeutic agents.

摘要:
A cable includes a plurality of bundles of insulated electrical conductors, each bundle having a first conductor, a second conductor, and a third conductor in a layered configuration. The first conductor of each bundle is connected in parallel to the first conductor of the remaining bundles, the second conductor of each bundle is connected in parallel to the second conductor of the remaining bundles, and the third conductor of each bundle is connected in parallel to the third electrical conductor of the remaining bundles. In addition, within each bundle, the first, second and third electrical conductors are configured so that a magnetic field generated in response to currents flowing within the bundle is zero as seen at a plane oriented transverse to an electrical conduction direction of the cable and located between the ends of the cable.
