THE LONG-RANGE GOAL OF THIS PROGRAM IS THE DEVELOPMENT AND COMMERCIALIZATION OF PROTON ACCELERATORS SUITABLE FOR RADIATION THERAPY OF CANCER IN HOSPITAL OR CLINICAL SETTINGS. FOR THIS PURPOSE THE ACCELERATOR SHOULD HAVE AN ENERGY UP TO 250 MEV, AND MUST BE SIMPLE, RELIABLE, AND INEXPENSIVE COMPARED TO EXISTING ACCELERATORS FOR PHYSICS APPLICATIONS. IN ADDITION, WITH SUFFICIENT INNOVATION, IT COULD ...

THE LONG TERM OBJECTIVE OF THIS PROJECT IS THE DEVELOPMENT AND MARKETING OF EASILY SWALLOWED ELECTRODES FOR TEMPORARY TRANSESOPHAGEAL CARDIAC PACING. THIS "PILL ELECTRODE" CAN REPLACE CARDIAC CATHETERIZATION IN A VARIETY OF DIAGNOSTIC AND THERAPEUTIC APPLICATIONS, INCLUDING INITIATION AND/OR TERMINATION OF TACHYCARDIAS, SHORT TERM MAINTENANCE OF ADEQUATE RATE IN SINUS BRADYCARDIA, ACCELERATION OF ...

A PAUCITY OF KNOWLEDGE EXISTS ABOUT NEONATAL TRACE ELEMENT NUTRITION REQUIREMENTS, ESPECIALLY FOR PREMATURE INFANTS, WHOSE CRITICAL FINAL TRIMESTER ACCUMULATION OF ESSENTIAL TRACE ELEMENTS IS ABRUPTLY CEASED AT BIRTH. THE OBJECTIVE OF THIS PROPOSAL IS TO DEVELOP THE SCIENCE AND TECHNOLOGY "BRIDGE" REQUIRED TO DEMONSTRATE THE FEASIBILITY OF DIRECT, OR NEARLY DIRECT, DETERMINATION BY RESONANCE IONIZ ...

TRACE ELEMENT NUTRITURE IS INCREASINGLY ACKNOWLEDGED AS A KEY ASPECT OF GROWTH, DEVELOPMENT, AND HEALTH. TRACE CHROMIUM MAY BE RELATED TO REGULATION OF INSULATION ACTION, RESTORATION OF IMPAIRED GLUCOSE TOLERANCE, AND THE CAUSAL

INSTRUMENTATION ENABLING QUANTITATIVE TRACE ELEMENT-CONCENTRATION IMAGING WITH HIGH SENSITIVITY AND RESOLUTION (1 PPM, 5 ) OF BIOLOGICAL TISSUE SECTIONS OVER 2X2MM(2) WOULD BE A VALUABLE RESEARCH TOOL. SIMULTANEOUS STRUCTURAL IMAGING WOULD ENHANCE ITS UTILITY. SPUTTER-INITIATED RESONANCE IONIZATION SPECTROSCOPY (SIRIS) WILL BE ADAPTED TO PROVIDE STRUCTURAL IMAGING AND QUANTITATIVE ELEMENT-CONCENTR ...

EMERGING HEALTH AND MEDICAL RESEARCH PROBLEMS ARE PLACING STRINGENT REQUIREMENTS ON THE ABILITY TO CHARACTERIZE LABILEAND HIGH-MOLECULAR-WEIGHT ORGANIC COMPOUNDS. IN BIOTECHNOLOGY, FOR EXAMPLE, INTERMEDIATE SYNTHESIS PRODUCTS MUST BE IDENTIFIED. RECENT ION BOMBARDMENT DESORPTION MODELS SUGGEST THAT HIGHEST-MOLECULAR-WEIGHT COMPOUNDS WOULDDESORB MOST EFFICIENTLY THROUGH RAPID, MULTIPLE EXCITATIONS ...

N/A

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP QUANTITATIVE ESTROGEN RECEPTOR CONCENTRATION MEASUREMENTS USING HIGH- RESOLUTION DIGITAL IMAGE MICROSCOPY TECHNIQUES. THE TECHNIQUES WILL ENABLE DIRECT MEASUREMENTS OF RECEPTOR CONCENTRATION ON A CELL-BY-CELL BASIS. THIS IS AN IMPROVEMENT OVER THE CURRENT BIOCHEMICAL ASSAYS, WHICH GIVE ONLY AN AVERAGE VALUE FOR RECEPTOR CONCENTRATION. THE QUANTITATIVE AS ...

IT IS PROPOSED TO DEVISE SEROLOGICAL METHODS FOR ROUTINE IDENTIFICATION OF MALE AND FEMALE BOVINE EMBRYOS, WITH A VIEW TO THE CONTROL OF SEX RATIO DURING COMMERCIAL EMBYRO TRANSFER. EMBRYOS WILL BE EXPOSED TO NEWLY DEVELOPED MONOCLONAL ANTIBODIES DIRECTED AGAINST MALE-SPECIFIC H-Y ANTIGEN AND THEN TO GOAT ANTIMOUSE-IG BEARING THE FLUORESCENT DYE, FITC. THE EMBRYOS WILL BE SCORED FOR LABELING UNDER ...
