The Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) seeks research partners, co-development partners, and/or licensees for hydrogels that can be used in tissue repair. Gels typically exhibit a decrease in mechanical strength (e.g., elastic modulus) upon swelling of the particles. The gels of this technology, however, exhibit an increase in mechanical strength upon swelling. The gels are comprised of a crosslinked polymer matrix dispersed in a crosslinked polymer matrix.
Researchers at the National Institute on Drug Abuse (NIDA) have developed an apparatus that is used to image rodents while they are awake. The biological effects of agents on the rats can be imaged (via MRI for instance) in real time over a prolonged period of time.
Researchers at the National Eye Institute (NEI), have developed a cryopreservation and cell recovery system designed specifically for the efficient cryopreservation, transportation and subsequent thawing of monolayers and tissues on a substrate. This closed cryopreservation/defrost system allows for sterility in addition to increased viability, recovery and safety of tissues that can be used for in vitro culture or surgical transplantation.
Researchers at the National Institutes of Health Clinical Center (NIHCC) and Northern Arizona University (NAU) seek licensing and/or co-development research collaborations for a wearable, pediatric, robotic exoskeleton that facilitates knee extension during walking to provide motorized movement assistance and training through the gait cycle. The Robotic Exoskeleton is specifically designed for therapy of crouch gait in children with cerebral palsy (CP). The design is a customizable human-machine interface that allows an individualized assistance protocol to help preserve and enhance muscle strength and control. Early clinical results from this intervention appear promising for a condition having few effective long-term interventions.
The National Cancer Institute (NCI) seeks research co-development opportunities and/or licensees for a new biomedical device for biopsy tissue collection and storage in a sterile, well-defined environment.
Researchers at the National Cancer Institute (NCI) have developed an engineered storage unit for frozen tissue, that provides a permanent base on which to mount tissue frozen in OCT and an enclosure for storage. The unit provides for chain-of-custody labeling and acts as an insulating container to protect the specimen. Other elements include devices for freezing the tissue to the base, as well as a holder for the base to facilitate cryosectioning. Application of the storage system allows a frozen tissue specimen to be moved between storage and cryosectioning without loss of label, deformation of tissue, or thermal alterations.
Researchers at the National Cancer Institute (NCI) developed a genetic assay for detecting transcription errors in RNA synthesis. This new assay extends the familiar concept of an Ames test which monitors DNA damage and synthesis errors to the previously inaccessible issue of RNA synthesis fidelity. The FDA requires genetic DNA focused tests for all drug approval as it assesses the in vivo mutagenic and carcinogenic potential of a drug. The new assay will open an approach to monitoring the impact of treatments on the accuracy of RNA synthesis. Errors in transcription have been hypothesized to be a component of aging and age-related diseases. The National Cancer Institute (NCI) seeks licensing partners for the genetic assay.
Scientists at the Eunice Kennedy Shriver National Institute for Child Health and Human Development (NICHD) have discovered that changes in the osmotic pressure of tissue or hydroscopic samples having a mass of less than about one microgram and that can exert a high osmotic pressure can be measured by this method.
The NICHD seeks research and co-development or licensees for a method of measuring small physical changes in small quantities of materials.
Surgery specialists from Johns Hopkins University, in collaboration with researchers at the National Cancer Institute (NCI), developed peptide hydrogel compositions and methods to suture blood vessels during microsurgery. The hydrogels particularly benefit surgeons in whole tissue transplant procedures. The NCI seeks co-development research collaborations for further development of this technology.
