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 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.
Pre-clinical radiotracer biomedical research involves the use of compounds labeled with radioisotopes, including cell binding studies, immune cell labeling techniques, and radio-ligand bio-distribution studies. Before this Micro-Dose Calibrator, measurement of pre-clinical level dosage for small animal studies was inaccurate and unreliable. This dose calibrator is a prototype ready for manufacturing. It is designed to accurately measure radioactive doses in the range of 50 nCi (1.8 kBq) to 100 µCi (3.7 MBq) with 1% precision. The NCI seeks co-development or licensing to commercialize it. Alternative uses will be considered.
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.
Researchers at the National Cancer Institute (NCI), in collaboration with surgery specialists from Johns Hopkins University, developed hydrogel compositions and methods to suture blood vessels with hydrogels during microsurgery. The hydrogels particularly benefit surgeons in whole tissue transplant procedures. The NCI seeks licensing and/or co-development research collaborations for further development of this technology.
