Functionalized Patterning of Tissue Engineering Substrates

Task also includes bioprinting cell-laden constructs for multi-compartment tissue chambers. Lyndon B. Johnson Space Center, Houston, Texas Tissue engineering (TE) is an emerging field for tissue repair and regeneration compared to conventional techniques including autograft and allograft, through engineering functional implants created from living cells. TE is a highly interdisciplinary research area where material science, engineering, and biology are blended to achieve tissue regeneration. Efforts have been made to regenerate liver, skin, bone, and vascular tissues by applying a tissue engineering approach. To generate any type of tissue in a laboratory environment, scientists need to mimic the cellular microenvironment by offering structural, chemical, physical, and biological cues to the cells. Introduction of these cues to the cellular environment starts with manufacturing a supportive matrix called a scaffold.

Hearing Test System Suitable for Self-Administered Hearing Assessment

Lyndon B. Johnson Space Center, Houston, Texas Astronauts have developed hearing loss in space, so the goal of this project was to provide a robust, self-administered, accurate noise-tolerance hearing test system for astronauts. The device includes Bekesy-like threshold audiometry, distortion product otoacoustic emission testing, and gap-detection testing.

The Dusk of Fire-Wire, The Dawn of USB 3.0: Advancements and critical aspects of camera interfaces for next generation vision systems

Before 2011, many system designs were built on the most popular interface at the time: FireWire. This technology is slowly becoming obsolete and is commonly being replaced by USB 3.0, the new predominant interface for industrial and scientific cameras. In this paper we will outline why people are making the upgrade from FireWire to the USB 3.0 interface, and why USB 3.0 is here to stay.

Universal Cell-Directed Nanotheranostics

A modified stem cell includes a micro or nano particle-based delivery system. Lyndon B. Johnson Space Center, Houston, Texas The present invention relates to the field of nanotechnology and, more particularly, to the field of delivery of active agents such as therapeutic and/or imaging agents using micro/nanoscale particles. Porous particles, such as porous silicon particles and porous silica particles, have a number of applications including use as drug delivery carriers. A need exists to develop new types of porous particles and new methods of using them for the treatment of diseases such as cancer.

Fluid Preservation System (FPS)

This system can be used by first responders during natural disasters.Biological samples contain labile molecules that deteriorate rapidly ex-vivo. Terrestrially, biological samples are preserved either by freezing them (–80 °C) or by including preservation chemicals. While chemical preservation may be ideal for certain molecules, their functionality is selective and can, while preserving one set of molecules, damage others. Refrigeration poses major logistical challenges of power and logistics. These two options pose major cost and logistics burdens to NASA as they continue to collect biological specimens during flight. Although the International Space Station (ISS) includes a refrigerator to preserve samples, there are no such capabilities aboard return vehicles, especially unmanned vehicles. Furthermore, it should be noted that payloads that are dropped off in remote locations often are recovered after many days, making the biological samples extremely vulnerable to ambient conditions, often rendering them useless.

Using Electromagnetic Time-Variance Magnetic Fields to Generate and Re-Grow Cartilage

Lyndon B. Johnson Space Center, Houston, Texas Adevice provides electromagnetic pulses at a predetermined frequency that will result in cartilage cell regeneration and regrowth for patients with arthritis, which reduces or eliminates joint cartilage. The device can be wrapped around the joints in a patient where infected cartilage is located. Molecular and marker data have shown this innovation to work as described above. This is a non-invasive technology that regenerates the patient’s own tissue, allowing for possibly no significant side-effects or foreign matter reactivity.

Computer-Aided Design Tools to Support Human Factors Design Teams

Marshall Space Flight Center, Alabama The purpose of this work was to develop a database of human model behavior primitives, which are basic scripts that can be chained together to create simulations of humans performing certain tasks. This is unique in that the human model behaviors were collected using motion capture technology and then incorporated into virtual simulation software. Typically, human model behaviors are created based on the subjective observations of the analyst rather than by using realistic motion data. Limitations of this approach include less reliable human models and a more time-consuming process for creating the human model in the virtual environment.
