Keynote Speakers Prof. Xiao-Long Wang College of Veterinary Medicine, Nanjing Agricultural University. Nanjing 210095, P.R. China. E-mail: wangxiaolong888@sohu.com Professor Wang with his research group recently are working on pathogenesis of pulmonary hypertension syndrome of broilers associated with pulmonary arterial remodeling which might be regulated by nitric oxide and expression of PKC. They have Published several interesting papers on the journals of UK and USA Prof. Robert F. Wideman, Ph.D. Associate Director and Professor of Poultry Physiology Center of Excellence for Poultry Science University of Arkansas Fayetteville, AR 72701 USA E-mail: rwideman@uark.edu Dr. Wideman has published numerous research articles on the pathophysiology of kidney damage and urolithiasis in poultry, as well as on pulmonary hypertension syndrome (PHS, ascites) in broilers. Research conducted in Dr. Wideman's laboratory revealed key genetic x nutrition x disease interactions, leading to a comprehensive understanding of the complex triggers for urolithiasis outbreaks in poultry.

Prof. Mark Pines, Ph.D. Director of the Institute of Animal Science The Volcani Center, P.O. Box 6 Bet Dagan, 50250 Israel Email: pines@agri.huji.ac.il Dr. Pines' recent research has focused on the molecular basis of bone disorders in poultry. Recent key publications include an outstanding review (Pines M, Hasdai A and Monsonego-Ornan E. (2005) Tibial dyschondroplasia - tools, new insights and future prospects World's Poult. Sci. J. 61, 285-297), as well as important reports on the molecular basis for tibial dyschondroplasia (Tong A, Reich A, Genin O, Pines M, Monsonego-Ornan E. (2003). Expression of chicken 75-kDa gelatinase B-like enzyme in perivascular chondrocytes suggests its role in vascularization of the growth plate.J Bone Miner Res 18(8):1443-52).
