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.
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) 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.
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 Eye Institute (NEI) developed a surgical tool to place tissue into position in the retina. The NEI seeks co-development or licensing to commercialize a prototype already in pre-manufacturing. Alternative uses will be considered.
This surgical clamp device is particularly useful for intraocular surgeries requiring incision in the sclera. The device provides ease of use for repeated opening and closure of an incision or wound for entry of instruments into the eye. It maintains precise alignment of the wound margins, reducing loss of intraocular fluid and pressure. The NEI seeks licensees or collaborative co-development of this invention so that it can be commercialized.
