    摘要： Antineoplastic dendritic polymer conjugates which are useful drug delivery systems for carrying antineoplastic agents to malignant tumors are prepared by obtaining a dendritic polymer having functional groups which are accessible to an antineoplastic agent capable of interacting with the functional groups, and contacting the dendritic polymer with the antineoplastic agent. The preferred platin-based analogues of the antineoplastic agents conjugated to the dendritic polymer may be administered intravenously, orally, parentally, subcutaneously, intramuscularly, intraarterially or topically to an animal having a malignant tumor in an amount which is effective to inhibit growth of the malignant tumor. The antineoplastic dendritic polymer conjugates exhibit high drug efficiency, high drug carrying capacity, good water solubility, good stability on storage, reduced toxicity, and improved anti-tumor activity in vivo.

    摘要： The present invention relates to novel therapeutic and diagnostic arrays. More particularly, the present invention is directed to dendrimer based multifunctional compositions and systems for use in disease diagnosis and therapy (e.g., cancer diagnosis and therapy). The compositions and systems generally comprise two or more separate components for targeting, imaging, sensing, and/or triggering release of a therapeutic or diagnostic material and monitoring the response to therapy of a cell or tissue (e.g., a tumor).

    摘要： A molded plastic cup comprising a generally cylindrical body portion, a rim and a handle, and a method of forming the cup. The body portion has an open upper end, and the rim extends radially outwardly from the perimeter of the open end of the body portion. The handle is formed as an integral part of the cup. The handle extends outwardly from substantially diametrically opposed portions of the rim and then along the rim on one side of the cup between the diametrically opposed portions. The end portions of the handle extend from the rim, and are sufficiently flexible to allow the handle to be bent upwardly from the rim so that the handle arches diametrically across the upper end of the cup. The entire cup is thermoformed from a single sheet of plastic.

    摘要： A novel process for preparing poly(2-isopropenyl-2-oxazoline or oxazine) and its methyl methacrylate copolymer, which are useful as water borne curing agents, particularly in the non-stick coating industry. The process converts commercially available poly(methyl methacrylate) into poly(2-isopropenyl-2-oxazoline or oxazine) polymers or copolymers with methyl methacrylate, while circumventing the use of the highly toxic monomer, 2-isopropenyl-2-oxazoline or oxazine. The process involves converting a poly(methacrylic ester) to the corresponding poly(.beta.-hydroxy-N-ethyl or propyl methacrylamide) and activating the ring-forming .beta.-hydroxy-N-ethyl or propyl methacrylamide moiety to form an oxazoline or oxazine ring.

    摘要： The level of residual 2-isopropenyl-2-oxazoline monomer in polymers prepared therefrom can be reduced by reaction of the protonated salt of the monomer with a variety of nucleophiles. The products of the reaction with the monomer are much less toxic than the 2-isopropenyl-2-oxazoline and the utility of the polymer is thereby enhanced. The reaction product of 2-isopropenyl-2-oxazoline and H.sub.2 SO.sub.3 is itself novel and useful.
