Researchers at UC San Diego have discovered that iron-containing nanoparticles being tested for use in several biomedical applications can be toxic to nerve cells and interfere with the formation of their signal-transmitting extensions.
Scientists at Johns Hopkins have identified the genetic culprits that trigger a hereditary form of a fatal lung disease. The findings, published in the March 29, 2007, issue of the New England Journal of Medicine, may provide new directions in diagnosis and treatment for families that inherit genes for the disease, as well as for those that develop non-inherited forms of the illness.
Soldiers exposed to the deafening din of battle have little defense against hearing loss, and are often reluctant to wear protective gear like ear plugs that could make them less able to react to danger. But what if a nutritious daily “candy bar” could prevent much of that potential damage to their hearing?
A study led by scientists from the University of North Carolina at Chapel Hill may have identified a molecular mechanism involved in the development of schizophrenia.
Women who have been diagnosed with breast cancer in one breast have a higher risk of contracting the disease in their opposite breast as well. A thorough examination of the opposite breast using mammography and ultrasound is therefore common practice.
A common asthma inhaler powered by a new propellant is safe and effective but could come at nearly triple the cost to consumers until a generic version hits the market, according to a review in today’s (March 29) New England Journal of Medicine.
DNA testing carried out by University of Leicester geneticists and funded by The Wellcome Trust has thrown new light on the ancestry of one of the USA?s most revered figures, the third President, Thomas Jefferson.
Compounds derived from the blue agave, a fruit used to make tequila, shows promise in early laboratory studies as a natural, more effective way to deliver drugs to the colon than conventional drug-carriers, according to chemists at the University of Guadalajara in Mexico.
If good genes spread through the population, why are people so different? A group of scientists think they have solved this long-standing puzzle.
Alan Garen, professor of molecular biophysics and biochemistry at Yale has received a $100,000 award from the Prostate Cancer Foundation to expand research on the delivery of a targeted therapy for prostate cancer using nanoparticles.
