Molds for Medical Technology

The demand for productivity in the field of medical consumables is consistently growing at a rapid rate. The growth of the world’s population, expanding urbanization, aging societies, and increasing self-medication are contributing to this growing demand, despite manufacturers’ limited production space. Costs continue to rise, and manufacturers are increasingly looking at stack molds for their capability to double the output while reducing waste.

Intranasal Scopolamine — INSCOP

This drug, in intranasal form, is an effective treatment for motion sickness. Lyndon B. Johnson Space Center, Houston, Texas Space motion sickness (SMS) commonly experienced by astronauts during a space mission often requires treatment with medication. However, exposure to a microgravity environment results in a myriad of physiological changes that alter bioavailability. In particular, studies indicate that the bioavailability of oral scopolamine (SCOP) is decreased during spaceflight. Although altered gastrointestinal function, including delayed gastric emptying, appears to contribute to decreased bioavailability of oral medications, other factors typical of spaceflight may influence the pharmacokinetics of medications administered via a variety of other non-parenteral routes.

Microbial Isolates from Research Activities as a Biological Resource

A collection of 1,530 individual isolates is used to evaluate the potential hazard of introducing sterilization-resistant microorganisms onto planetary spacecraft. NASA’s Jet Propulsion Laboratory, Pasadena, California International treaty requires spacecraft landing on planetary surfaces that may have water present, or may have supported life in the past, to adhere to strict guidelines governing the microbial contaminants that are incidentally present in, and on, spacecraft hardware introduced to those environments. Precautions to prevent microbial contamination of flight hardware are taken throughout assembly, test, and launch operations to minimize transferring biological contamination to the planet. Effectiveness of these precautions is assessed by conducting bioassays of spacecraft surfaces and assembly areas to estimate the number of microorganisms present. Microorganisms discovered are preserved as a living document and compendium for the mission. The organisms that are of greatest concern are those that are highly resistant to desiccation and spacecraft sterilization by dry heat.

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.

Avoiding Common Mistakes in Extractables/Leachables Program Design

Mistakes in program design for extractables/leachables testing can lead to significant delays, rounds of questions, and the need for additional testing. And, in some cases, all of the extractables/leachables testing may need to be repeated. To avoid these costly mistakes, it is important to understand the current standards as well as the current interpretations and opinions from regulators interpreting these standards. In this whitepaper the experts from WuXi AppTec discuss the current standards, interpretations and will provide you with tips to avoid common mistakes when designing your program.

Provision of Carbon Nanotube Buckypaper Cages for Immune Shielding of Cells, Tissues, and Medical Devices

This method may prevent the rejection of transplanted cells and tissue. Ames Research Center, Moffett Field, California NASA has patented a new technology that may prevent the rejection of transplanted cells and tissues. The human immune system identifies and rejects non-host cells and tissues with high efficiency. The new invention involves the fabrication and use of carbon nanotube buckypaper (CNTBP) “cages” for immune shielding. This approach promotes and supports a variety of useful biological processes that are difficult or impossible when cells or tissue are maintained in culture outside the body. It allows for the transplantation of cells or tissues from unrelated donors or from unrelated species (xenografts) into host subjects with dramatically reduced potential for rejection and/or the use of immunosuppressive therapies, which can be highly toxic. Current strategies for islet cell transplantation, for example, have shown marginal success due to limited graft survival, even with immunosuppressive therapy.
