Vitamin D May Halt Lung Function Decline In Asthma And COPD
Vitamin D may slow the progressive decline in the ability to breathe that can occur in people with asthma as a result of human airway smooth muscle (HASM) proliferation, according to researchers at the University of Pennsylvania.

House Panel Passes Protection For Drug Makers
The House Energy and Commerce Committee passed an amendment to their broad health reform bill giving drug makers 12 years of exclusive rights to market new biologic drugs, "a setback" to the administration and consumer advocates who hoped to make generic drugs more widely available, the Wall Street Journal reports. The panel voted 47-11 on the measure, which "would also allow "evergreening," the practice by pharmaceutical companies of making minimal adjustments to their drugs, such as creating extended-release versions, as a way to lengthen their monopoly."

Removing Arsenic From Drinking Water: Guanajuato Will Be First To Try Rice's 'Nanorust'

Rice University researchers have announced that the first field tests of "nanorust," the university"s revolutionary, low-cost technology for removing arsenic from drinking water, will begin later this year in Guanajuato, Mexico. "Mexico"s debating the adoption of more stringent national standards for allowable levels of arsenic in drinking water, and officials in Guanajuato are looking ahead to explore ways they might meet stricter new standards," said nanorust inventor Vicki Colvin, Rice"s Pitzer-Schlumberger Professor of Chemistry and director of Rice"s Center for Biological and Environmental Nanotechnology (CBEN). Colvin and CBEN faculty, staff and students began visiting Guanajuato last fall to prepare for the upcoming tests. Guanajuato, which has a population of 80,000, is the capital of Guanajuato state. It is about 230 miles northwest of Mexico City. Arsenic is a colorless, odorless, tasteless element, and prolonged exposure to dangerous levels of arsenic can lead to skin discoloration, sickness and cancer. Arsenic-poisoned drinking water is a global problem, affecting tens of millions of people in communities in Asia, Africa, North America, South America and Europe. CBEN"s arsenic-removing technology is based on the unique properties of particles called "nanorust," tiny bits of iron oxide that are smaller than living cells. In 2006, Colvin and CBEN colleague Mason Tomson, professor in civil and environmental engineering, published with their students the first nanorust studies. Their initial tests indicated nanorust -- which naturally binds with arsenic -- could be used as a low-cost means of removing arsenic from water. Qilin Li, an assistant professor of civil and environmental engineering and CBEN faculty expert in water treatment, said Rice"s team plans to test nanorust-coated sand. The material will be used in sand filters to treat groundwater from wells. The water treated with nanorust will be kept separate from the water that is released for human consumption, Li said. "Our studies of nanorust have progressed rapidly over the past three years, but in order to move this technology toward practical application there is really no substitute for this type of field test," Li said. Pedro Alvarez, the George R. Brown Professor of Engineering and chair of the Department of Civil and Environmental Engineering, said, "One collateral benefit of the nanorust filters is that they may also help remove water-borne viruses that are responsible for a wide variety of gastrointestinal diseases."
