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.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
