Researchers have investigated the associations between ammonia, air pollution, socioeconomic status, and access to medical care with incidence and mortality rates of salivary cancer in the South Carolina population. The findings from this study revealed that an association was found between emissions of ammonia and mortality rates of salivary gland cancer in Caucasian men.
Nearly 2,900 new cases of salivary gland cancer will be diagnosed in the United States in 2004, an increasing number, and no one knows why. Some studies suggest environmental factors may play a role, but no definitive data have been presented.
Ammonia is an agent that has been implicated in cancers of the stomach but is not known as a risk for salivary gland cancer. The study, “Salivary Gland Cancer Mortality and Industrial Ammonia Emissions: A Geographic Association,” examines that concept. The authors Edward D. Gorham, Ph.D, and Frank C. Garland, Ph.D both of the Naval Health Research Center San Diego, CA, and the Department of Family and Preventive Medicine University of California, San Diego, Terry Day, M.D, Medical University of South Carolina, Charleston, SC, Cedric F. Garland, Dr.P.H, Department of Family and Preventive Medicine University of California, San Diego, and Franky Hasibuan, M.P.H., GEO Centers, Inc., San Diego, CA, will present their findings at the 6th International Conference on Head and Neck Cancer being held August 7-11, 2004, at the Marriott Wardman Park in Washington, DC.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...
Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles
Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
