Houston Chronicle, Nov. 4, 2006 http://www.chron.com/disp/story.mpl/business/4309886.html Spurred by America's relentless appetite for anything that will slow the aging process, a Japanese pharmaceutical company has picked Pasadena as its U.S. base to manufacture a health supplement that is a hit in Japan.  Earlier this week, Kaneka Corp. opened an $80 million plant and hired more than 70 employees in Pasadena to make Coenzyme Q10. The antioxidant is a key ingredient in a variety of products that claim to alleviate the signs of aging and to boost energy levels. Studies conducted by the National Institute of Neurological Disorders and Stroke, University of Texas and Texas A&M University, among others, have shown that the supplement may help patients with Parkinson's, Alzheimer's and high blood pressure, according to Dr. Hans Langsjoen, associate professor of neurology at the University of Texas Medical Branch in Galveston. Langsjoen is a second-generation researcher of CoQ10 who has no financial connection to Kaneka.
