"GeneXpress Informatics, Inc. (GXI) and Dr. James P. Chambers of UTSA propose to develop a revolutionary differential gene display technology, called Preferential Display (PD) which will provide for a simplified, cost-effective method to identify thesegenes for use in discovering gene expression… More

GeneXpress Informatics, Inc. (GXI) and Dr. James P. Chambers of the University of Texas at San Antonio propose to use GXI's patent pending, Preferential Display (PD) technology to identify and isolate stress-related gene expression transcripts for the use in developing a real-time bioreactor… More

Exposure of humans to chemical or biological warfare agents has been demonstrate to be detected within hours of contact by measuring gene expression levels (profiles) on a genomic scale using microarray chips. While this technology has been shown to bedeployable in the field, the human genomics… More

During the Phase I, GeneXpress Informatics (GXI) provided proof-of-concept for the Preferential Display (PD) technology. GXI's Preferential Display (PD) technology is a paradigm shift in high throughput gene expression and analysis. The PD technology eliminates redundant sequences found between… More

Technology is needed to provide real-time assessment and evaluation of hematological parameters during prolong space flights and planetary missions. A key hematological parameter is the monitoring and measurement of emboli in the brain especially during Extra-Vehicular Activity (EVA) on planetary… More

GeneXpress Informatics, Inc. (GXI) proposes to develop a Multi-IMmunotoxicity Assay System (MIMAS) based upon the Luminex Corporation (Austin, TX) xMAP system, a flexible analyzer based on the principles of flow cytometry. The proposed MIMAS will utilize three core technologies. The first is the… More

Returning men to the Moon and manned Mars missions will require advanced bioastronanutics research. One possible risk is Decompression Sickness (DCS) resulting from extravehicular activity (EVA), after exposure to habitat conditions that would be generated using available Moon or Martian resources.… More

GeneXpress Informatics, Ten X Technology and the University of Texas Health Science Center at San Antonio (UTHSC-SA) has developed and demonstrated a Multi-ImmunoMagnetic Assay System (MIMAS) with a detection limit of 2 attograms/ml for a human IL-15 assay which is 6 orders of magnitude more… More

The DoD has funded a number of nanotechnology based obscurant projects. Recent studies have shown the potential health and environmental risk associated with nanoparticle exposures. Development of biologically based obscurants could eliminate these shortcomings by providing multi-spectral… More

In Phase I, GeneXpress Informatics (GXI) and Dr. James P. Chambers of the University of Texas at San Antonio proposed to develop biological obscurants for battlefield applications based on the use of bacteriochlorophylls. Upon completion and presentation of results to MARCORSYSCOM, GXI and Chambers… More

Studies have shown the potential health and environmental hazards associated with hexachloroethane (HC) and terephthalic (TA) smoke/obscurants. In order to avoid using these materials, new chemical formulations are needed to address toxicological concerns and yet still maintain Grenade Figure of… More
