Interactive electronic whiteboards in the medical classroom.
Most research on computer-assisted instruction has concentrated on developing systems to be used outside the teaching environment to supplement or complement in-class teaching. We believe that interactive large-screen computers can be used effectively in the classroom as electronic whiteboards to more effectively teach select medical school courses. We describe our experience with one such device, the Xerox LiveBoard, to teach a course on computer-assisted clinical decision analysis to a group of first-year medical students.

Information retrieval using a "digital book shelf".
WALT (Washington University's Approach to Lots of Text), is a prototype interface designed to support information retrieval research. The WALT interface serves as a "front end" to a wide array of retrieval engines including those based on Boolean retrieval, latent semantic indexing, term frequency--inverse document frequency, and Bayesian inference techniques. The WALT interface is composed of seven distinct components: a document examination component known as the Document Browsing Area; four navigation components called the Book Shelf, the Book Spine, the Table of Contents, and the Path Clipboard; a term-based information retrieval component called Control Panel; and a relevance feedback component known as the Reader Feedback Panel. WALT's most unique feature may be it's use of "book shelf" and "book spine" metaphors both to facilitate navigation and to provide a histogram-based display showing documents deemed appropriate for answering user queries.

Plasma transcobalamins in haematological disorders.
Plasma UBBC-B12 and transcobalamins were measured in 112 patients suffering from different haematological disorders. The data showed different patterns of changes in plasma transcobalamin profile in different haematological disorders. Plasma UBBC-B12 and transcobalamins were significantly higher than normal in untreated chronic myeloid leukaemia, acute promyelocytic leukaemia, nutritional megaloblastic anaemia and in refractory anaemias with hypercellular marrow. Normal levels of these proteins were noted in chronic lymphatic leukaemias, in primary and secondary hypereosinophilic states and in multiple myeloma. Subnormal levels of these proteins were observed in hypoplastic anaemia and acute lymphoblastic leukaemia. Chronic myeloid leukaemia patients during blast crisis and acute myeloid leukaemia patients except those suffering from acute promyelocytic leukaemia showed varying pattern of plasma transcobalamins depending on type of blast crisis or FAB subtype of AML. The significance of these changes in plasma transcobalamins have been discussed along with the experience of other workers in this field.
