The technology holds promise for millions of people in India, Bangladesh and other developing countries where thousands of cases of arsenic poisoning each year are linked to poisoned wells.

More than 8.3 million single nucleotide polymorphisms (SNPs) were discovered among the genomes of the 15 mouse strains and the data are now publicly available. These new data will help researchers better understand complex genetic traits, such as why some individuals are more susceptible to certain diseases, and will serve as a valuable resource in determining how environmental agents influence the development of disease.

New research presented at CHEST 2006, the 72nd annual international scientific assembly of the American College of Chest Physicians (ACCP), shows that when used in combination, inhaled salmeterol (SAL) and fluticasone propionate (FP) reduced the risk of dying by up to 17.5 percent in patients with COPD. Currently, FP, an inhaled corticosteroid, and SAL, a long-acting B2-agonist bronchodilator, are used alone and in combination to treat both asthma and COPD.

This has led to the visualization of how human cells interact with some specific types of carbon nanoparticles. The method is described in a review article on carbon nanoparticle toxicity in a special section of the August 23, 2006, issue of the Journal of Physics: Condensed Matter devoted to developments in nanoscience and nanotechnology, now available online.

Screening asymptomatic patients is an important strategy for reducing these deaths, because by the time patients experience symptoms, the cancer may have progressed beyond the point where it can be cured. Generally, physicians recommend that patients begin screening at age 50 years, the authors write. However, physicians might recommend that individuals with certain risk factors, including family history, begin screening at earlier ages. Screening methods include flexible sigmoidoscopy, which involves inserting a flexible optical instrument through the rectum into the lower portion of the large intestine, and colonoscopy, which involves inserting a longer flexible optical instrument through the rectum and into the entire colon, is more expensive, has higher complication rates and usually is performed by a gastroenterologist or surgeon rather than a primary care physician.

The insights therefore suggest potential new avenues for the development of anti-inflammatory and pain medications, according to the researchers.
