The more we get, the more we need: Study shows how to prevent morphine 'tolerance'
11-01-2007 · EurekAlert!Tolerance to the pain-relieving effects of morphine -- which builds rapidly with prolonged use -- can be prevented by blocking a substance that's formed when the drug is taken, researchers at Saint Louis University have discovered. Their findings could lead to new therapies that allow morphine to be administered without patients becoming tolerant of it -- a significant obstacle to effective pain relief -- nor experiencing a host of severe side effects that accompany escalating doses of the painkiller.

- First-ever study: lack of critical lubricant causes wear in joints
11-06-2007 · EurekAlert!
For the first time, researchers have linked increased friction with early wear in the joints of animals. Work led by Brown University physician and engineer Gregory Jay, MD, shows mice that do not produce the protein lubricin begin to show wear in their joints less than two weeks after birth. This finding not only points up the protective power of lubricin but also suggests that it could be used to prevent joint wear after an injury.

- Novel MS drug shows promise in 2 lethal leukemias
08-28-2007 · EurekAlert!
A new study suggests that an experimental drug being tested for the treatment of multiple sclerosis and to prevent organ rejection might also help people with certain deadly forms of chronic and acute leukemia. The laboratory and animal study focused on the drug, called fingolimod. Researchers said it might help patients with advanced chronic myelogenous leukemia or acute lymphocytic leukemia, and whose cancer cells show a particular genetic change called the Philadelphia chromosome.

- Ski area affects mountain watershed, UVM study shows
05-17-2007 · EurekAlert!
In the first-ever study to document the effects of ski resort development on water flows and quality in the northeastern US, University of Vermont researchers studied side-by-side watersheds on Mount Mansfield. Their results show greater-than-expected water volume from the developed watershed, suggesting that models derived from timber extraction studies may underestimate the hydrologic effects of resort development. This study provides baseline data that may contribute to new stormwater management approaches in mountainside development.

- Early family intervention alters preschoolers' biological response to stress
10-01-2007 · EurekAlert!
Researchers have been studying family interventions that prevent young children from following in the footsteps of their older delinquent siblings. Now a new study shows that a non-medical early family intervention that improves caregiving also results in important changes in children's biological response to stress.

A 17-year University of Utah study of ground movements shows that the power of the huge volcanic hotspot beneath Yellowstone National Park is much greater than previously thought when the giant volcano is slumbering. Findings show gradual ground movements overpower quake movements at Yellowstone, and the hotspot makes the Teton fault behave unexpectedly.

- Bioabsorbable stent shows excellent performance
03-24-2007 · EurekAlert!
The use of slow-release drugs in stents (drug-eluting stents) has dramatically reduced restenosis rates after percutaneous coronary intervention. However, these permanent metal devices may impair coronary imaging, predispose patients to late stent thrombosis, prevent positive remodeling and hinder revascularization. A study presented today at the American College of Cardiology's Innovation in Intervention: i2Summit assesses the safety and performance of a bioabsorbable stent that, if effective, could eliminate several of the problems associated with metallic stents.
