摘要： A method and means for providing functional equivalents to organs wherein cells are grown on polymer scaffolding using cell culture techniques followed by transfer of the polymer-cell scaffold into a patient at a site appropriate for attachment, growth and function, after growth and vascularization. Once the structure is implanted and vascularization takes place, the resulting organ is a true blend of the parenchymal elements of the donated tissue and vascular and matrix elements of the host. A key element of the method is to design and construct the polymer scaffold using a material and shape that provides for attachment and growth of the cells such that adequate nutrients and oxygen are supplied to the inner layers of the cells by diffusion, until such time as implantation and vascularization occur.

摘要： A new class of poly(beta-amino alcohols) (PBAAs) has been prepared using combinatorial polymerization. The inventive PBAAs may be used in biotechnology and biomedical applications as coatings (such as coatings of films or multilayer films for medical devices or implants), additives, materials, excipients, non-biofouling agents, micropatterning agents, and cellular encapsulation agents. When used as surface coatings, these PBAAs elicited different levels of inflammation, both in vitro and in vivo, depending on their chemical structures. The large chemical diversity of this class of materials allowed us to identify polymer coatings that inhibit macrophage activation in vitro. Furthermore, these coatings reduce the recruitment of inflammatory cells, and reduce fibrosis, following the subcutaneous implantation of carboxylated polystyrene microparticles. These polymers may be used to form polyelectrolyte complex capsules for cell encapsulation. The invention may also have many other biological applications such as antimicrobial coatings, DNA or siRNA delivery, and stem cell tissue engineering.

摘要： Aminoalcohol lipidoids are prepared by reacting an amine with an epoxide-terminated compound are described. Methods of preparing aminoalcohol lipidoids from commercially available starting materials are also provided. Aminoalcohol lipidoids may be prepared from racemic or stereochemically pure epoxides. Aminoalcohol lipidoids or salts forms thereof are preferably biodegradable and biocompatible and may be used in a variety of drug delivery systems. Given the amino moiety of these aminoalcohol lipidoid compounds, they are particularly suited for the delivery of polynucleotides. Complexes, micelles, liposomes or particles containing the inventive lipidoids and polynucleotide have been prepared. The inventive lipidoids may also be used in preparing microparticles for drug delivery. They are particularly useful in delivering labile agents given their ability to buffer the pH of their surroundings.

摘要： The present invention generally relates to systems and methods for releasing a releasable species from an article using an external trigger, for example, using microwave radiation or other forms of radiation, e.g., radiofrequency radiation. Such systems and methods may be useful, for example, in biological applications (e.g., as an implant within a subject), industrial applications, commercial applications, or the like. One aspect of the invention is generally directed to an article containing a radiation- sensitive polymer or other radiation-sensitive material. Exposure of the radiation- sensitive material to radiation such as microwave and/or radiofrequency radiation may cause the material to increase in temperature. This increase in temperature may be used, in some cases, to cause the release of a drug or other releasable species from the article. For instance, a drug may be contained in a heat-sensitive material positioned in thermal communication with the radiation-sensitive material, or a drug may be contained within an enclosure that is isolated, at least in part, by a heat-sensitive material positioned in thermal communication with the radiation-sensitive material. In another aspect of the invention, a receive antenna, such as a microwave receive antenna may be used to focus microwave and/or radiofrequency radiation on an article. For instance, the receive antenna may focus microwave and/or radiofrequency radiation on a radiation-sensitive material in the article. Such focusing may be useful, in some embodiments, to control release of a drug or other releasable species from the article. Other aspects of the invention are directed to systems and methods of making or using such articles, e.g., by implanting the article within a subject, methods of treatment involving such articles, kits including such articles, and the like.

摘要： The present invention provides compositions and methods for noninvasive delivery of therapeutic agents across an intact tympanic membrane. For example, the compositions include a penetration enhancer which increases the flux of a therapeutic agent (e.g., antibiotic) across the tympanic membrane. Such compositions are particularly useful in the treatment of otitis media. Additionally, the composition may include a sustained release agents that, in some embodiments form sustained release reservoirs, in situ, once administered to a patient.
