Adding albuterol, a compound commonly used to treat asthma and other respiratory diseases, to an existing treatment for patients with multiple sclerosis appears to improve clinical outcomes, according to a report in the September issue of Archives of Neurology, one of the JAMA/Archives journals.

A pilot study suggests the diabetes medication pioglitazone is generally well tolerated and may warrant further study as a treatment for patients with Alzheimer's disease, according to a report posted online today that will appear in the January 2011 print issue of Archives of Neurology, one of the JAMA/Archives journals.
Taking oral antiviral medications following infection with the herpes simplex virus may be associated with a reduced risk of recurring eye-related manifestations of the disease, according to a report in the September issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
(New York, NY) Nearly half the surgeons who made at least $1 million in payments from orthopedic device companies did not have that relationship published in their scientific articles, according to a study released today in the on-line edition of the Archives of Internal Medicine. The study shows that readers are not being adequately informed about conflicts of interest even when the funds involved are significant.
When looking for a new physician, patients are often encouraged to select those who are board certified or who have not made payments on malpractice claims. Yet these characteristics are not always a good predictor of which physicians will provide the highest quality medical care, according to a new study from the RAND Corporation, a nonprofit research organization, and the University of Pittsburgh School of Medicine.
WASHINGTON, September 13 – Developing renewable energy sources has never been more important, and solar photovoltaic (PV) technologies show great potential in this field. They convert direct sunlight into electricity with little impact on the environment. This field is constantly advancing, developing technologies that can convert power more efficiently and at a lower cost.
STANFORD, Calif. - Repeated use of an antibiotic that is considered generally benign, because users seldom incur obvious side effects, induces cumulative and persistent changes in the composition of the beneficial microbial species inhabiting the human gut, researchers at the Stanford University School of Medicine have found.
DAVIS--A research team from the University of California, Davis and Peking University, China, has discovered a novel mechanism as to why the long-term, high-dosage use of the well-known arthritis pain medication, Vioxx, led to heart attacks and strokes. Their groundbreaking research may pave the way for a safer drug for millions of arthritis patients who suffer acute and chronic pain.
An unusual wildflower that accumulates metals in its leaves has been found to use them as a kind of 'armor' against bacterial infection. Scientists from Oxford University have shown that when Alpine pennycress (Thlaspi caerulescens) plants accumulate metals in their leaves, they become resistant to attack by the bacterium Pseudomonas syringae pv. maculicola. They report their findings September 9 in the open-access journal PLoS Pathogens.
RIVERSIDE, Calif. – Molecular machines can be found everywhere in nature, for example, transporting proteins through cells and aiding metabolism. To develop artificial molecular machines, scientists need to understand the rules that govern mechanics at the molecular or nanometer scale (a nanometer is a billionth of a meter).
A study led by researchers at the BC Centre for Excellence in HIV/AIDS (BC-CfE) at St. Paul's Hospital and the University of British Columbia has found that supervised injection facilities such as Vancouver's Insite connect clients with addiction treatment, which in turn resulted in greater likelihood of stopping injection drug use for at least six months.
The study, recently published in the peer-reviewed journal Drug and Alcohol Dependence, is the first ever to examine the link between a supervised injection facility and injection cessation.
Gainesville, FL. -- The first genetic study to compare nuclear DNA of endangered Antillean manatees in Belize with Florida manatees confirmed their designation as separate subspecies. Belize's manatees, however, were found to have extremely low genetic diversity, raising questions about their long-term genetic viability.
The Central American country of Belize hosts the largest known breeding population of Antillean manatees and is touted by biologists for its potential to repopulate other parts of Central America where manatees are severely reduced, rare or absent.
In work suggesting a new approach to treating polycystic kidney disease (PKD), a leading cause of kidney failure, researchers at Children's Hospital Boston were able to block the formation of fluid-filled cysts, the hallmark of the disease, in a mouse model. Their findings, using a compound that inhibits a receptor known as c-Met, will be published in the September 13th online edition of the Journal of Clinical Investigation.
New York (September 13, 2010) - A protein crucial for the immune response appears to be a key player in the progression of a devastating form of childhood leukemia called T-cell acute lymphoblastic leukemia (T-ALL). Suppressing the activity of the protein kills the leukemic cells, the study shows, opening a potential avenue to new drugs that could prevent progression of the disease.
