THE APPLICATION OF PHYSICAL-CHEMICAL PRINCIPLES TO BIOLOGICAL SYSTEMS FREQUENTLY LEADS TO SITUATIONS IN WHICH THE QUANTITATIVE TREATMENT OF CONCEPTUALLY SIMPLE MODELS IS CONFOUNDED BY THE COMPLEXITY OF THE SYSTEM. SUCH IS THE CASE, FOR EXAMPLE, IN THE STUDY OF THE PERMEATION (AND POSSIBLE CONCURRENT METABOLISM) OF DRUGS THROUGH COMPLEX BIOLOGICAL MEMBRANES, THE PHYSIOLOGICAL MODELING OF THE DISTRI ...

TECHNICAL RESEARCH ASSOCIATES, INC. PROPOSES THE DEVELOPMENTOF A NOVEL PLATELET-HARVESTING SYSTEM BASED ON A PREVIOUSLY DEVELOPED ULTRASOUND SEPARATION TECHNOLOGY. THIS TECHNOLOGY, DEVELOPED UNDER AN NHLBI GRANT, ALLOWS THE SEQUENTIAL SEPARATION OF CELLS BASED ON THEIR SIZE, EVEN THOSE CELLS THAT HAVE IDENTICAL DENSITIES. FIRST, RESIDUAL ERYTHROCYTES AND LARGE LEUKOCYTES CAN BE SEPARATED FROM PLAT ...

THE LONG-TERM OBJECTIVE OF THIS PROJECT IS TO DEVELOP A PROTOTYPE SCANNING SYSTEM FROM WHICH NOVEL AND ADVANCED ULTRASOUND SCANNING SYSTEMS CAN BE MANUFACTURED FOR THE IMAGING, TISSUE CHARACTERIZATION, AND DIAGNOSIS OF CANCER AND OTHER DISEASES. IT WILL GIVE SUPERIOR IMAGES OF OBSTETRICAL CONDITIONS, VASCULAR DISEASE, LIVER DISEASE, ANDOTHER ABDOMINAL CONDITIONS. THIS ADVANCED SYSTEM IS BASED ON E ...

Magnetic resonance imaging (MRI) is a powerful tool for the diagnosis of a broad range of clinicalconditions. Expensive contrast media (about $110.00/dose) contribute to its high cost. We will performthe preliminary steps necessary for a pre-IND evaluation by the FDA of a new inexpensive agent,Gadolinium DTPA Bisglucosamide. Preliminary investigations show lower animal toxicity, improvedgadolinium ...

DESCRIPTION (Provided by Applicant): The implications of developing materials with enhanced fracture toughness, damage resistance, reliability and ultra low wear is of significant interest to the orthopedic community, since it directly addresses a vital clinical concern- eliminating wear debris mediated THA implant failures. In Phase I we made a significant ...

There are many data acquisition systems available for neuroscientists interested in multi-channel neurophysiology but all use proprietary, independently-developed file formats for the acquired data. This creates several problems including difficulties in sharing data between laboratories and poor interoperability between equipment, data processing tools and spike classification software from diffe ...

DESCRIPTION (applicant's abstract): Our long-term goal is to advance techniques and instrumentation for rapid, automated analysis of nucleic acids during amplification. Our approach is to add fluorescent probes before amplification and analyze the results in real-time, completing the entire process in 10-20 min. No additional sample processing, membranes, arrays, or ...
