Evaluating an interdisciplinary undergraduate training program in health promotion research.

Background: The University of California at Irvine Interdisciplinary Summer Undergraduate Research Experience (ID-SURE) program had three objectives: (1) designing an interdisciplinary health promotion training curriculum for undergraduate research fellows; (2) developing measures for evaluating and assessing program-related educational processes and products; and (3) comparing these educational process and product measures between groups of students who did or did not receive the training.

Methods: A total of 101 students participated in the ID-SURE program during 2005, 2006, and 2007. A longitudinal research design was employed whereby students' interdisciplinary attitudes and behaviors were assessed at the beginning and end of the training program.

Choice, Degree of Preference, and Happiness Indices with Persons with Intellectual Disabilities: A Surprising Finding.

Two persons with severe intellectual disabilities and two persons with profound intellectual disabilities were repeatedly presented with five different pairs of food items. The five pairs of items represented different degrees of preference, from highest to lowest. Happiness indices were monitored from the time that a pair of items was presented until a choice was made.

Structure of pteridine reductase (PTR1) from Leishmania tarentolae.

The protozoan parasites Leishmania utilize a pteridine-reducing enzyme, pteridine reductase (PTR1), to bypass antifolate inhibition. The crystal structure of PTR1 from L. tarentolae has been solved as a binary complex with NADPH at 2.
