People who must stay awake for long shifts "“ soldiers, pilots, truckers, students, doctors, parents of newborns "“ may take comfort from new research showing that preventing the gas nitric oxide from building up in the brain may ward off the sleep urge. The research, conducted by investigators from Children's Hospital Boston and the University of Helsinki (Helsinki, Finland), ties together previous observations about sleep and finds that nitric oxide production in a specific...

By Gene Emery BOSTON (Reuters) - Letting some premature babies inhale small amounts of nitric oxide may prevent a potentially fatal lung disease known as bronchopulmonary dysplasia, two studies showed on Wednesday. Thousands of babies are born each year in the United States with lungs too immature to properly mix inhaled air with blood so that the oxygen can be pumped to the cells of the body. Progress in fighting the problem, which can cause brain damage, has been limited. The...

By Lisa Lambert WASHINGTON (Reuters) - Hundreds of U.S. chemical plants, companies and utilities have reduced their odds of being sabotaged and turned into deadly weapons by changing the chemicals they use or by moving, a think tank said on Tuesday. The liberal Center for American Progress found that 284 facilities took steps such as switching from using chlorine gas, ammonia and sulfur dioxide to less hazardous materials to process food or treat wastewater. Others removed their...

By Karla Gale NEW YORK (Reuters Health) - High blood levels of an enzyme called lactate dehydrogenase (LDH) predict complications in patients with sickle cell disease, a disorder in which red blood cells cannot delivery oxygen properly because the cells have abnormal sickle shape, new research shows. "Using modern technology, we reconfirmed that a very big source of LDH in the blood stream of patients with sickle cell disease is from the breakdown of red blood cells," not from the cell...

Researchers at the Georgia Institute of Technology and the John Innes Centre in the United Kingdom have uncovered a mechanism with which disease-causing bacteria may thwart the body's natural defense responses. The findings, which could ultimately lead to the development of more effective antibiotics, appear in the September 29, 2005 issue of the journal Nature. "Nitric oxide is produced by the body to fight infections. We discovered a mechanism that allows bacterial cells to detect nitric...

Researchers have found that an important chemical compound, nitric oxide, appears to slow or reverse the aging of eggs in mouse ovaries. The finding suggests nitric oxide could one day help women in their 30s and 40s remain fertile longer and increase their chances of having healthy babies, the scientists say. The finding, by investigators at Wayne State University School of Medicine in Detroit, was published in the Aug. 30 issue of the American Chemical Society's journal Biochemistry. In...

A new study from the Brady Urological Institute at Johns Hopkins suggests an over-supply of a simple blood sugar could be a major cause of erectile dysfunction in diabetic men. Researchers have found that one particular simple sugar, present in increased levels in diabetics, interferes with the chain of events needed to achieve and maintain erection and can lead to permanent penile impairment over time. The results, which have implications for new types of erectile dysfunction treatments...

Wound healing is slow when an animal is stressed, but extra oxygen almost completely reverses the effect, according to researchers at the University of Illinois at Chicago. In a study of laboratory mice, Phillip Marucha, professor of periodontics at the UIC College of Dentistry, and his colleagues found that psychological stress, brought on by confinement, delayed the closing of wounds by more than 45 percent. A range of cell and genetic changes accounted for the slow recovery. "The cells...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
