Chromatid Painting for Chromosomal Inversion Detection

Applications include clinical cytogenetics, biomedical research, and biodosimetry. Lyndon B. Johnson Space Center, Houston, Texas Chromosomal inversions, such as those occurring following exposure to ionizing radiation, are especially difficult to detect by current techniques. Therefore, their true frequency and importance have been underappreciated. Even the impressive technology of whole genome sequencing, which is becoming more readily and rapidly available, is useless for the detection of many chromosomal rearrangements within a chromosome. Likewise, stateof- the-art cytogenetic mBAND analysis of irradiated normal human tissue can only occasionally reveal radiationinduced inversions. A novel and innovative approach called differential Genomic Hybridization (dGH) or chromatid painting has been developed to further explore, expand, and capitalize on this new frontier of molecular cytogenetics.

Guidelines for Meal Replacement Bars in a Space Food System

Emergency relief organizations, food banks, the military, and food service markets all have use for the bars due to their nutritional offering and long shelf life. Lyndon B. Johnson Space Center, Houston, Texas To decrease the mass of the space food system and still maintain the nutritional intake of a mission crew, meal replacement bars and beverages are desired to supplement the menu and serve as meal alternatives. Nutritional requirements for such replacement products for breakfast and lunch have been established based on the current nutritional delivery of the International Space Station standard menu.

Assisting An Aging Population: Designing Medical Devices With Force Sensing Technology

With the geriatric population on the rise, design engineers are challenged with designing responsive, noninvasive, user-friendly medical devices that cater to the needs of an older generation. Patients are looking for cost-effective, easy to use assistive tools that help them regain independence and confidence in their everyday life. Force feedback is a key feature for many of these devices that provide the user and doctor with great insight that ultimately results in better quality of life for the patient. Medical devices with force feedback allow design engineers to create innovative products that differentiate them from the competition.

Medical 3D Printing and Additive Manufacturing: Going From Why to How

3D printing has been utilized in the medical industry for over 20 years. In recent years, the number of applications, utilization, and utility have increased exponentially. This increase has been driven by two key factors: (1) crossing the chasm from “how to print” to “why adopt 3D printing and additive manufacturing”, and (2) the dramatically increased selection of technologies and materials that meet the needs of medical professionals.
