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 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.
