Multiplexing Homocysteine in Primary Newborn Screening Assays Using Maleimides as Select Derivatization Agents
Mouse Embryo Culture Chamber and Imaging System and Methods of Use
The culture of mouse embryos ex utero and continuous monitoring and imaging of embryos as they develop have applications in drug testing, genetic studies, and basic research on embryonic development. However, the embryo culture systems currently available for post-implantation embryos include rolling bottle culture systems, which do not permit imaging of the developing embryos and do not support the long-term survival and development of embryos ex utero.
Micro-Dose Calibrator for Pre-clinical Radiotracer Assays
Molecular imaging is a disease-specific targeting modality that promises much more accurate diagnoses of serious diseases such as cancer and infections. Agents are being continually developed with a view to clinical translation, with several such therapies requiring measurement of very small doses. Currently, there is no way of accurately measuring small amounts of radioactivity used in many pre-clinical tracer studies, as on-the-market commercial dose calibrators measure at too high a dose range, typically at 10-1000 µCi and higher.
A Specialized Tissue Collection Device for the Preservation and Transportation of Needle Biopsies
The ability to hold and transport tissue, especially needle biopsies in a pre-defined and controlled environment is critical for the preservation of biopsy samples in downstream analytic applications. Currently, tissue specimens are placed in open containers with variable, poorly controlled solutions applied to them, often in less than sterile conditions. Evaluation of the tissue by examination through a stereoscope or similar approaches to determine adequacy is limited and requires manipulation of the tissue that can further damage the tissue.
Radiographic Marker for Portable Chest and Abdominal X-Rays
The NIH Clinical Center seeks parties interested to license a method and apparatus that can significantly improve the diagnostic performance of portable chest (CXR) and abdominal x-rays. This device (see image below) quantifies angulation of a patient to provide for a better comparison of day-to-day improvement. Potential applications include portable chest and abdominal x-rays performed at patient's hospital bedside.
Development Status:
A Preclinical Model for Mutant Human EGFR-driven Lung Adenocarcinoma
Previously described epidermal growth factor receptor- (EGFR) driven tumor mouse models develop diffuse tumors, which are dissimilar to human lung tumor morphology and difficult to measure by CT and MRI scans. Scientists at the National Cancer Institute (NCI) have developed and characterized a genetically engineered mouse (GEM) model of human EGFR-driven tumor model (hEGFR-TL) that recapitulates the discrete lung tumor nodules similar to those found in human lung tumor morphology.
A Preclinical Orthotopic Model for Glioblastoma Multiforme that Represents Key Pathways Aberrant in Human Brain Cancer
Current therapies for glioblastoma multiforme (GBM), the highest grade malignant brain tumor, are mostly ineffective, and better preclinical model systems are needed to increase the successful translation of drug discovery efforts into the clinic. Scientists at the National Cancer Institute (NCI) have developed and characterized an orthotopic genetically engineered mouse (GEM)-derived model of GBM that closely recapitulates various human GBM subtypes and is useful for preclinical evaluation of candidate therapeutics.
