Abstract:
In one aspect, the invention provides mesoporous silica nanoparticles (MSNPs), monodisperse populations of MSNPs and related protocells which exhibit single cell binding specificity to the substantial exclusion of non-targeted cells. For example, MSNPs and protocells of the invention may be used to target specific delivery of therapeutic agents to cancer cells or to specific blood vessel types (e.g. in the arterial, venous and/or capillary vessels or any combination of vessels). Related protocells, pharmaceutical compositions and therapeutic and diagnostic methods are also provided.
Abstract:
The invention provides novel antibiotic protocells comprising mesoporous nanoparticles encapsulated within a lipid bi- or multilayer. The nanoparticles have pore sizes and surface chemistries that enable facile adsorption and intracellular presentation of antibiotics which are effective in the treatment of a wide variety of bacterial infections, including F. tularensis, B. pseudomallei and P. aeruginosa-related infections. Related pharmaceutical compositions and methods of treatment are also provided.
Abstract:
The present invention is directed to methods of determining the presence or absence of a bacterial infection in a patient using isotopically-labeled tyrosine and/or isotopically-labeled p-hydroxyphenylacetic acid.
Abstract:
Novel particular-based pesticides formed from pesticidal agents encapsulated in one or more coatings wherein the coating enhances the pesticidal agent' s ability to control a pest population, and methods for making the same. In various embodiments the pesticidal agent may be a biopesticide and the coating may impart stability, protection from UV radiation and/or other environmental conditions, enhance the attractiveness of the pesticide to the pest, and/or serve to separate two different biologically incompatible pesticides within a mixture.
Abstract:
Embodiments of the present invention provide for the facile generation of a stable recombinant fusion polypeptides with intrinsic fluorescent properties. The recombinant antibodies may be suitable for qualitative and/or quantitative immunofluorescence analysis. Generally, the fluorescent polypeptides include a fluorescent domain comprising a C-terminus and an N-terminus; a first antibody domain covalently linked to the C-terminus; and a second antibody domain covalently linked to the N-terminus.
Abstract:
A device for coating dry powder microparticles onto a surface may include a jet mill configured to mill dry powder particles into microparticles having a desired aerodynamic diameter and to deaggregate the microparticles, a feed hopper structured and arranged to feed dry powder particles to the jet mill, a surface configured to receive dry powder microparticles and an exit nozzle associated with the jet mill. The exit nozzle may be arranged to direct deaggregated micronized dry powder particles from the jet mill to the surface to be coated. The device may further include a holder structured and arranged to hold an item, wherein the item includes the surface. In some aspects of the device, the item may be a film.
Abstract:
The present invention relates to the use of a mutant CRP molecule in which tyrosine 175 is replaced by leucine (Y175L CRP) or the leucine 176 is replaced by glutamic acid (L176E CRP) for the treatment of various disease states and conditions associated with SLE, including lupus of the skin (discoid), systemic lupus of the joints, lungs and kidneys, hematological conditions including hemolytic anemia and low lymphocyte counts, lymphadenopathy and CNS effects, including memory loss, seizures and psychosis, among numerous others as otherwise disclosed herein. In another aspect of the invention, the reduction in the likelihood that a patient who is at risk for an outbreak of a disease state or condition associated with SLE will have an outbreak is an additional aspect of the present invention. The present invention relates to the use of mutant Y175L CRP or L176E CRP in the treatment of a number of disease states or conditions that occur secondary to systemic lupus SLE. The present invention also relates to the treatment of immune thrombocytopenic purpura. Pharmaceutical compositions are also disclosed based these mutant CRP molecules.
Abstract:
The present invention is a method and system for developing a dynamic scheme for Gamma Knife radiosurgery based on the concept of "dose-painting" to take advantage of robotic patient positioning systems on the Gamma Knife C and Perfexion units. The spherical high dose volume created by the Gamma Knife unit will be viewed as a 3D spherical "paintbrush", and treatment planning is reduced to finding the best route of this "paintbrush" to "paint" a 3D tumor volume. Under the dose-painting concept, Gamma Knife radiosurgery becomes dynamic, where the patient is moving continuously under the robotic positioning system.
