Largest ever overactive bladder study published in leading urology journal
The University Hospital of Maastricht today announced clinical trial results that demonstrate that patients taking a new, once-daily formulation of tolterodine, currently marketed in the U.S. as DETROLĀ® LA (tolterodine tartrate tablets), reported a 71% reduction in incontinence episodes per week compared to 60% in patients treated with the twice- daily formulation of DETROL.

Researchers pinpoint event that led to Mars' heyday
Planetary scientists at Washington University in St. Louis and various collaborators have concluded that the Tharsis rise in Mars' Western Hemisphere is key to many of the Red Planet's mysteries, including its large-scale shape and gravity field, and its early climate and water distribution.

Depression may increase risk of death from heart disease
Depression increases the risk of dying from heart disease, sometimes dramatically, according to research conducted in Holland and being published by a Wake Forest University faculty member in the March issue of Archives of General Psychiatry.

Sleeping dogs lend a paw to narcoleptics
Give a treat to a narcoleptic dog, and he's likely to pass out with excitement - an endearingly pitiful sight.

Researchers identify an enzyme that regulates the action of chronic cocaine
In a new finding that could have major implications for treatment of addiction, scientists have found that an enzyme called Cdk5 regulates the action of chronic cocaine in the brain.

Treatment for HIV disease found cost effective
Three-drug combination therapy for AIDS, in spite of its great expense, is a very cost-effective use of resources, report researchers from Massachusetts General Hospital and their colleagues.

UCSF studies illuminate possible new landscape for targeting cancer
Dual UCSF findings dramatize what scientists have just begun to recognize: While so-called oncogenic cells drive the development of cancerous tumors, other, seemingly innocent cells -- inflammatory cells - within emerging tumors can influence the fate of tumors, their aggression and their response to therapy.

Family important source of support for HIV-positive men
People diagnosed with HIV often turn to friends for support, and that's encouraged by doctors and therapists, but new research suggests this advice may not go far enough, says Julie Serovich, a researcher who has studied HIV-infected men since 1997 under a grant from the National Institutes of Mental Health.

Faster nanowires may advance nanotechnological applications for detecting glucose, hormones or DNA
Teeny-tiny wires capable of connecting with the kinds of molecules that make up the human body could be building blocks for what may be among the first nanotechnology applications: biological sensors for detecting glucose levels in diabetics, measuring hormone levels in menopausal women or identifying DNA at crime scenes.

Insulin in worms
In a search for the worm equivalent of human insulin, researchers from Massachusetts General Hospital made several findings that may change the way that the scientific community thinks about insulin and its related proteins.

Advance directives found key to reducing stress for families of hospitalized patients at the end of life
Researchers report that stress levels are extremely high for family members who must decide whether or not life support should be withdrawn from relatives too incapacitated to decide for themselves.
