Point 1: the American Veterinary Medical Association Council on Education's (AVMA COE's) accreditation pro-cess is aimed at minimum training for entry-level veterinarians. This has a two-fold consequence: 1. The opportunity to discover the absolute minimum number of necessary resources is opened.

Founded in 1884 by the University's Medical Faculty, the School has been a leader in moulding the education and practice of veterinary medicine in the nation and the world. Successfully integrating biomedical research into all aspects of veterinary medical education, the School has made significant contributions to basic and clinical research by exemplifying 'One Medicine'.

Studies in human patients, animal models, and companion animals have revealed different but complementary aspects of the aging process, ranging from fundamental biologic aspects of aging to the treatment of age-related diseases, both experimentally and in clinical practice. Participants concluded that neither animal nor human research alone will provide answers to most questions about the aging process.

While some molecules, including those involved in inflammatory/immune responses, have been implicated in the control of sleep, their role in this process remains unclear. The Drosophila model for sleep provides a powerful system to identify and test the role of sleep-relevant molecules.

One of the most consistent behavioral changes that occurs with age in humans is the loss of sleep consolidation. This can be quite disruptive and yet little is known about its underlying basis. To better understand the effects of aging on sleep:wake cycles, we sought to study this problem in Drosophila melanogaster, a powerful system for research on aging and behavior.

We tested the effect of modafinil, a novel wake-promoting agent, to discover whether its effect is conserved. Flies fed various concentrations of modafinil were compared to groups of control flies fed diluent only.

During the past century, flies thoroughly proved their value as an animal model for the study of the genetics of development and basic cell processes. During the past three decades, they have also been extensively used to study the genetics of behavior. For both circadian rhythms and for sleep, flies are helping us to understand the genetic mechanisms that underlie these complex behaviors.

To test the hypothesis that genes that are components of the molecular clock also regulate rest, the authors quantified the duration and intensity of consolidated rest and activity for the four viable Drosophila mutations of the central clock that lead to arrhythmic locomotor behavior and for the pdf mutant that lacks pigment-dispersing factor, an output neuropeptide. Only the cycle (cyc01) and Clock (Clk(Jrk)) mutants had abnormalities that mapped to the mutant locus, namely, decreased consolidated rest and grossly extended periods of activity.
