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.
Abstract:
A neutron irradiation history sensor and detection method for detection of thermal neutrons exploit transmutation of 164Dy into 165Ho and 166Er and significant differences in optical properties of Dy, Ho, and Er in order to enable detection of relative fractions of Dy, Ho, and Er and thus the degree and timing of prior thermal neutron exposure that has occurred, providing a tamper-proof forensic record of the prior thermal neutron exposure. The irradiation history sensor and detection method advantageously employ Dy-containing nanocrytals (NCs) residing in a transparent host.
Abstract:
The present disclosure provides multi-walled carbon nanotubes and carbon nanotubes (CNTs) displaying catalytic enzymes bound to the nanotube sidewalls and devices, such as electrodes, incorporating these catalytic enzyme-bound CNTs (cebCNTs).
Abstract:
Hollow conjugated polyelectrolyte (HCPE) microcapsules contain at least one conjugated polyelectrolyte and at least one other polyelectrolyte of complementary charge and the microcapsule has a hollow core. The conjugated polyelectrolyte is a polymer with a multiplicity of charged repeating units where a portion of the charged repeating units form a pi-conjugated sequence. The complementary polyelectrolyte is a polymer with a complementary charged repeating unit to the charged repeating units of the conjugated polyelectrolyte. The HCPE microcapsules can be formed by successively coating a sacrificial core with alternating layers of complementary polyelectrolytes, at least one of which is a conjugated polyelectrolyte. The sacrificial core can be removed to form the hollow center of a HCPE microcapsule. The HCPE microcapsules can be contacted with a medium containing microbes where the HCPE microcapsules associate with the microbes and efficiently kill the microbes when irradiated with light or other electromagnetic radiation.
Abstract:
The present invention relates to molecules which function as selective modulators of the Ras-homologous (Rho) family of small GTPases, in particular, Cdc42 GTPase and their use to treat diseases, for example cancers, including metastatic cancer, genetic and acquired diseases where activation of Cdc42 GTPase plays a pivotal role, such as neurodegenerative diseases, rheumatoid arthritis, atherosclerosis, diabetes type I, autosomal polycystic kidney disease, cystic kidney disease, precystic kidney disease, microbial infections, including Chlamydia infections, E. coli infections, H. pylori infections and its secondary effects including gastric ulcers, Coxiella Brunetti (Q-fever) infections and Streptococcus pneumonia infections, fungal infections including Paracoccidiodes brasiliensis and Candida albicans and their secondary effects including lung edema. Additionally, compounds according to the present invention may be used to inhibit rejection in transplant patients (pursuant to transplantation), to promote immunosuppression, anti-inflammatory response and to mobilize stem cell (migration) in patients in need, among others.
Abstract:
The present invention is directed to novel non-invasive diagnostic tools/compounds comprising a cyclic peptide wherein the compound binds to a MSH receptor to image and treat cancers, especially, melanoma, including metastatic melanoma in vivo. The present invention represents a clear advance in the art which presently relies on tissue biopsy for diagnoses of these cancers. The novel imaging probes are capable of detecting cancerous melanoma cells, as well as their metastatic spread in tissues. The present invention represents a step forward in the diagnosis and treatment of melanoma, including metastatic melanoma using non-invasive molecular imaging techniques. The novel probes of the present invention are also useful to initiate therapy for melanoma as well as monitor patients response to chemotherapy treatments and other interventions or therapies used in the treatment of melanoma/metastatic melanoma. Compounds according to the present invention may be used as diagnostic tools for a number of conditions and diseases states as well as therapeutic agents for treating such conditions and disease states.
Abstract:
Swellable particles for delivering a working agent to the pulmonary system comprise a plurality of biodegradable particles each formed from a polymer network, each of the plurality of biodegradable particles having a mass mean aerodynamic diameter not exceeding 5 μm, the particles being swellable by hydration to a size that is greater than 6 μm volume mean diameter, and a working agent entrapped in the polymer network of each of the plurality of biodegradable particles.
Abstract:
Various embodiments provide methods of forming zero valent metal particles using an aerosol-reductive/expansion synthesis (A-RES) process. In one embodiment, an aerosol stream including metal precursor compound(s) and chemical agent(s) that produces reducing gases upon thermal decomposition can be introduced into a heated inert atmosphere of a RES reactor to form zero valent metal particles corresponding to metals used for the metal precursor cot pound(s).
Abstract:
The current invention is in the field of molecular biology/pharmacology and provides compounds which modulate the effects of GPR30 as well as the classical estrogen receptors alpha and beta (ERα and ERβ). These compounds may function as agonists and/or antagonists of one or more of the disclosed estrogen receptors. Diseases which are mediated through one or more of these receptors include cancer (particularly breast, reproductive and other hormone-dependent cancers, leukemia, colon cancer, prostate cancer), reproductive (genito-urological) including endometreitis, prostatitis, polycystic ovarian syndrome, bladder control, hormone-related disorders, hearing disorders, cardiovascular conditions including hot flashes and profuse sweating, hypertension, stroke, obesity, osteoporosis, hematologic diseases, vascular diseases or conditions such as venous thrombosis, atherosclerosis, among numerous others and disorders of the central and peripheral nervous system, including depression, insomnia, anxiety, multiple sclerosis, neuropathy, neurodegenerative disoders such as Parkinson's disease and Alzheimer's disease, as well as inflammatory bowel disease, Crohn's disease, coeliac (celiac) disease and related disorders of the intestine. A contraceptive indication to prevent or reduce the likelihood of pregnancy after intercourse is a further aspect of the present invention.
