Urine-Sample-Collection Device for Use on the Space Shuttle
The in-flight urine collection absorber (IUCA) is a Johnson Space Center (JSC) breakthrough. It features a lightweight, compact design and is easy to use for collection of urine samples by male and female space shuttle crewmembers. The IUCA is superior to currently available hardware for...
Briefs: Medical
Wearable sensor patches — miniature biotelemetric units — have been proposed for use in measuring temperature, heart rate, blood pressure, and possibly other physiological parameters. The...
Briefs: Medical
A technique for noninvasive determination of the pressure in the cerebrospinal fluid (CSF) has been proposed. This technique would involve two main steps: First, an optical coherence tomographic...
Briefs: Medical
An improved solution for preserving samples of urine has been formulated. This solution preserves a much broader spectrum of analytes in urine than do other urine-preservative solutions here-tofore in use by NASA,...

Primers for Amplifying CMV DNA in Body Fluids and Tissue
A novel set of primers has been developed for use in a polymerase chain reaction (PCR) to amplify the deoxyribonucleic acid (DNA) of cytomegalovirus (CMV). The purpose of this development is to enable faster, more sensitive detection of CMV virus infecting body fluids and tissues.
Briefs: Medical
A whole-blood-staining device provides a means of (1) staining white blood cells by use of monoclonal antibodies conjugated to various fluorochromes, followed by (2) lysing and fixing of the cells by use of a...

Portable Device for Chemical Fixation of a Biological Sample
The Kennedy Space Center (KSC) fixation tube is a device for chemical fixation of a biological sample. It is mechanically resilient, small, and easy to use, and is thus well suited to use in the field as well as in the laboratory. Because typical chemical fixatives are extremely...
Briefs: Medical
A material developed for space suits has been found useful in a completely different application: making wicks to support seedlings and to carry water and nutrients to them during the initial stages of...
Briefs: Medical
An improved suit to be worn by a worker during abrasive blasting has been developed. Denoted an environmentally controlled abrasive-blasting suit (ECAB), it provides comprehensive protection...

Exoskeletal System for Neuromuscular Rehabilitation
A system of sensors and actuators designed to fit on the lower extremities of human patients and astronauts like an exoskeleton is under development to serve diverse purposes in neuromuscular research and rehabilitation. This system will be operated under both Earth and microgravity conditions. A...
Briefs: Medical
A noninvasive medical-imaging system produces false-color images that show regions of ischemia (reduced oxygenated blood flow) in organs and tissues. The system operates in real time, providing immediate...

Neutrophil-Screening Assay Using Two-Color Flow Cytometry
An in vitro test that includes the use of two-color flow cytometry has been developed for use in screening of neutrophils for their ability to fight infections. Neutrophils constitute the first line of defense of the human body against infections. Neutrophils engulf invading bacteria in a...
Briefs: Medical
A compact fiber-optic probe has been found to be useful for noncontact diagnosis of interior parts of eyes. The probe was originally developed for performing...
Briefs: Medical
A method of measuring the concentration of a selected organic compound (analyte) in a sample of water involves (1) producing hydrogen peroxide as a byproduct of enzyme-catalyzed...
