Two infectious bursal disease vaccines were administered to separate groups of maternally immune and susceptible chickens at various ages. Vaccine B caused no damage to the bursae of chickens examined histologically at nine and 20 days after vaccination. The bursae of chickens given vaccine A were shown to be severely damaged when similarly examined. Both(More)
We are developing a prototype storytelling robot for use with children in rehabilitation. Children can remotely control a large furry robot by using a variety of body sensors adapted to their disability or rehabilitation goal. In doing so, they can teach the robot to act out emotions (e.g. sad, happy, excited) and then write stories using the storytelling(More)
We are developing a prototype storytelling robot for use with children in rehabilitation. Children can remotely control a furry robot by using a variety of body sensors adapted to their disability or rehabilitation goal. We believe this robot can motivate children and help them reach their therapy goals through therapeutic play, either by exercising muscles(More)
Scytonema hofmanni, a filamentous freshwater cyanobacterium (blue-green alga), produces secondary metabolites which inhibit the growth of other cyanobacteria and green algae. A rapid, qualitative assay for this inhibition has been developed with Synechococcus as the test organism. This assay procedure has led to the isolation and characterization of an(More)
BACKGROUND Cesarean delivery is the most common surgical procedure performed in the USA. We evaluated the postoperative analgesic properties of neuraxial hydromorphone compared to neuraxial morphine for post-cesarean delivery analgesia. METHODS A retrospective chart review was performed of women who underwent cesarean delivery and received neuraxial(More)
The depression of response of Brucella abortus strain 19 caused by an infectious bursal disease vaccine virus given to chicks at one day old was shown to persist for four weeks. Histological examination of the bursa of Fabricius showed a gradual repopulation by bursal lymphocytes, after initial damage, concomitant with the development of a humoral response.
