New data examines effect of inhaled corticosteroids (ICS) on survival in patients with chronic obstructive pulmonary disease (COPD)
The findings of a retrospective database study examining the effect of inhaled corticosteroids (ICS) on survival in COPD patients1 were presented today at the American College of Chest Physicians CHEST 2002 Annual Conference in San Diego.
The investigators identified male and female patients, ages 40 and older, who were enrolled in the Lovelace
Aspirin may reduce ovarian cancer growth, a laboratory study by the USF College of Medicine has shown.
The study, published in the October issue of the journal Obstetrics and Gynecology, demonstrated that aspirin inhibited ovarian tumor cell growth by as much as 68 percent. The higher the dosage of aspirin added to the culture of ovarian cancer cells, the more growth inhibition was observed.
The researchers also found that combining aspirin with a monoclonal antibody specific for th
Drug users with access to controversial syringe-exchange programs are up to six times less likely to put themselves at risk of HIV infection, according to a new UC Davis study published in the November issue of Journal of Acquired Immune Deficiency Syndromes.
“While programs to control the spread of HIV by providing clean needles to drug users remain controversial in California and around the country, this study clearly shows that syringe-exchange programs save lives — and save society mil
Scientists and engineers build the transistors that run televisions, radios and similar electronic devices based on the moving electric charges of electrons. But the electron also has another key property: a magnetic “spin” that scientists believe could be exploited to develop faster, smaller and more efficient devices.
The first step is to determine the magnetic properties of materials that could be used to create futuristic nanoscale devices, a task that has escaped scientists until now.
In a finding that could open the door to future treatments for many genetic diseases such as sickle cell anemia and muscular dystrophy, researchers have produced high levels of transplanted, healthy stem cells in mice, while sharply reducing a hazardous side effect of cell and organ transplants called graft-versus-host disease.
By combining prenatal transplants of blood-forming stem cells with manipulations of blood cells after birth, researchers at The Childrens Hospital of Philadelphia a
Study finds expectation of humor has a biological effect on body
Go ahead, laugh. In fact, look forward to the upcoming positive event. It does the body good.
Yes, even looking forward to a happy, funny event increases endorphins and other relaxation-inducing hormones as well as decreases other detrimental stress hormones, a UC Irvine College of Medicine-led study has found.
In previous studies, the scientists found that anticipating a funny video reduced feelings
