Abstract:
A method of measuring the concentration of a magnetic material in an object using magnetic resonance imaging comprising administering magnetic material to the object; obtaining a set of T1-weighted and T2-weighted images of the object in order to determine a background magnetic resonance imaging signal intensity and measurements of the background nuclear magnetic relaxation times (T1, T2) of the object without magnetic material; and obtaining a set of T1-weighted and T2-weighted magnetic resonance images of the object with magnetic materials added; measuring effect of magnetic material on the relaxation times; and converting the T1-weighted and T2-weighted images into a set of contrast images which are subtracted from each other to yield a contrast difference image proportional to the concentration of the magnetic material.
Abstract:
Methods and composition for treating or preventing pulmonary hypertension are provided. In certain aspects, compounds that inhibit TH17 cell maturation or activity, such as retinoic acid receptor-related orphan nuclear receptor (ROR) inhibitors, are used to for the treatment of pulmonary hypertension.
Abstract:
The present invention is an apparatus and method for delivering energy using a renewable resource. The method includes providing a photovoltaic energy source and applying energy storage to the photovoltaic energy source via a battery storage unit. The energy output from the photovoltaic energy source and the battery system is controlled using a battery control system. The battery control system predicts peak load, develops a schedule that includes when to begin discharging power and when to stop discharging power, shifts power to the battery storage unit when excess power is available, and prioritizes the functionality of the battery storage unit and the photovoltaic energy source.
Abstract:
Thiophene containing water-soluble oligomers were synthesized and characterized. The photophysical properties of these compounds were studied; transient absorption spectroscopy was used to probe the triplet excited state and their ability to sensitize singlet oxygen was spectroscopically monitored in deuterated methanol. The above compounds were tested for their light activated biocidal properties against S. aureus both under UV and visible radiation. Among the oligomers studied, the terthiophene derivative was found to kill the bacteria efficiently.
Abstract:
Compositions and methods for the detection, prevention, or treatment of anthrax or other infectious diseases. In one aspect, the present invention provides methods for immunizing humans or animals against Bacillus anthracis or other capsulated pathogens. The methods include administering a capsular polypeptide of a pathogen of interest and a CD40 agonist to a human or animal. The capsular polypeptide or the CD40 agonist is administered in such an amount or frequency that an immunoprotective response can be elicited in the human or animal against the pathogen of interest. In another aspect, the present invention provides methods of using passive immunization with anti-capsular polypeptide antibodies to prevent or treat infections caused by Bacillus anthracis or other pathogens. In yet another aspect, the present invention provides methods useful for diagnosis of anthrax by detection of capsular polypeptide in serum or other biological samples.
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.
Abstract:
Active multifunctional nanoparticles provide significant enhancement of the efficacy of model therapeutic and gene agents due to increased diffusion and penetration through mucus and biological barriers under the influence of a magnetic field.
Abstract:
A supported bi-metallic non-platinum catalyst that is capable of oxidizing hydrazine to produce, as by-products of energy production, nitrogen, water, and zero or near-zero levels of ammonia is described. The catalyst is suitable for use in fuel cells, particularly those that utilizes an anion-exchange membrane and a liquid fuel such as hydrazine.
Abstract:
A pliable pressure sensitive sensor device and method of making the same is provided. The sensor includes first and second pliable protective layers, which cover sets of conductive fibers that spatially separated by an electrically conductive pliable layer, which deforms in response to a pressure event. The fiber sets form a grid pattern and are in electrical communication with sets of electrical contacts located in predetermined locations along the fibers. In response to a pressure event in proximity to the contact, the pliable layer deforms and increases the amount of surface area in contact with an electrical contact whereby an electrical resistance at an individual electrical contact decreases in response to the pressure event.
Abstract:
A dynamically reconfigurable framework manages processing applications in order to meet time-varying constraints to select an optimal hardware architecture. The optimal architecture satisfies time-varying constraints including for example, supplied power, required performance, accuracy levels, available bandwidth, and quality of output such as image reconstruction. The process of determining an optimal solution is defined in terms of multi-objective optimization using Pareto-optimal realizations.
