Counting number of endothelial cells in blood may predict cancer treatment's effectiveness

Counting the amount of a type of normal cell circulating in the blood of people with cancer could predict whether a tumor progresses or responds to therapy, a new study led by the University of Michigan Comprehensive Cancer Center has found. The finding could give doctors an early indication of whether a treatment will be successful, sparing patients months of an ineffective therapy.

Magnetic stimulation treatment for depression

Barbara Baas ran away from home and tried to kill herself as a teenager. As an adult, she has tried more than 15 varieties of antidepressants. But, thanks to a new weapon, she has finally reached a truce in a 45-year battle.

Breast CT may improve on mammography - more gentler, more accurate

A new breast screening technology that may be able to detect tumors earlier than mammography -- without the need for uncomfortable breast compression -- is being tested in patients at the University of California, Davis, Medical Center.

Research offers new molecular approaches to therapies for the most deadly cancers

Researchers at Wake Forest University Baptist Medical Center have found promising new molecular targets and treatment approaches for some of the most malignant brain tumors.

Cytogen Corporation and Dowpharma collaborate to create a targeted oncology product designed to treat prostate and other cancers

Under the agreement, Dowpharma's proprietary MeO-DOTA bifunctional chelant technology will be used to radiolabel Cytogen's prostate-specific membrane antigen (PSMA) antibody with a therapeutic radionuclide. PSMA is a protein highly expressed on the surface of prostate cancer cells and the neovasculature of many solid tumors.

African Americans and Caucasians viewing African American faces display extremely similar changes in the activity of brain structures that respond to emotional events

The changes occur in the amygdala, a region of the brain that serves as an "alarm" to activate a cascade of other biological systems to protect the body in times of danger, said Matthew D. Lieberman, assistant professor of psychology at UCLA and lead author of the study.

Clues about how alcoholic behavior is “switched” on

As part of an ongoing effort to understand the biochemical basis of alcohol abuse, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have published two studies on how modulating receptors for dopamine - a chemical “signaler” in the brain’s reward circuits - affects drinking behavior in mice and rats.

"Anxiety Gene" linked to depression, makes the body out of tune

U.S. scientists in viewing the human body as a well-tuned orchestra, say that think they may have found a discordant note in the form of a gene which appears to increase the likelihood of some people developing anxiety and depression.

$Soft tissue injuries can predict risk of facial fractures in trauma patients$

Soft tissue injuries can predict risk of facial fractures in trauma patients

Trauma patients with specific types of facial soft tissue injuries should have a CT (computed tomography) scan of the face as well as a standard head scan to determine the presence and severity of facial fractures, according to a study published in the May issue of the Journal of Oral and Maxillofacial Surgery.

Promising new molecular targets and treatment approaches for some of the most malignant brain tumors

The first study identified a protein that seems to control the malignant features of brain tumor cells, suggesting a new treatment target for anti-cancer drugs. Researchers found that a little-known protein called Fra-1 was effective in controlling vascular endothelial growth factor D, a factor that promotes the growth of new blood vessels in most malignant brain tumors.

Suspect gene may increase susceptibility to anxiety and depression

People with the depression-linked gene variant showed less gray matter and weaker connections in the mood-regulating circuit. How well the circuit was connected accounted for nearly 30 percent of their anxious temperament

Impact of acupuncture goes beyond the acknowledged placebo effect

Researchers at the University of Southampton and University College London have shown for the first time that the impact of acupuncture goes beyond the acknowledged placebo effect caused by the patient's own expectation of feeling benefit from the treatment.

Abnormal heart scans predict higher risks for African-Americans and Hispanics

SPECT imaging scans show that abnormalities in blood flow to the muscle of the heart indicate higher cardiovascular disease risk in African-Americans and Hispanics than similar abnormalities in white patients, according to a new study (PDF) in the May 3, 2005, issue of the Journal of the American College of Cardiology.

MRI study shows hormone leptin alters brains, may ease cravings of people with obesity gene

A magnetic resonance imaging (MRI) study finds that the protein hormone leptin promotes development of gray matter in the part of the brain that regulates cravings and the ability to monitor personal behavior.

Fusing physics with medicine to fight cancer

Everyone’s lives are touched by cancer - it is a disease that affects 1 in 3 of us throughout our lifetime. Future developments that lead to earlier diagnosis and more effective therapy lie in further successful collaboration between high energy physicists and the healthcare industry.

Breast cancer screening situation will get worse

According to a recently published study, community-based mammography facilities do not have enough radiologists and certified technologists to adequately deliver screening and diagnostic services to the public, and the situation will probably get worse.

Search for new multiple sclerosis drug

UT Southwestern Medical Center is the lead research site testing a new treatment for a rare form of multiple sclerosis. Called "primary progressive," this type of MS affects about 15 percent of patients with the neurodegenerative disease.

Use of positron emission tomography may eliminate more strenuous drug development trials with animals

A number of articles explore the use of positron emission tomography (PET) and small animal imaging—nonsurgical techniques that open the door to understanding and treating human diseases—in the April issue of the Society of Nuclear Medicine’s Journal of Nuclear Medicine.

New statin study shows arrested progression of atherosclerosis

The first study to use cutting edge magnetic resonance imaging to examine the effect of a statin - rosuvastatin (Crestor) - on the fatty plaques in arteries, was presented yesterday at the 75th European Atherosclerosis Society Congress. ORION revealed that rosuvastatin has a beneficial effect on the size and composition of fatty plaques in arteries (specifically the carotid artery in the neck). Fatty plaques that are vulnerable to sudden rupture can cause heart attacks and strokes without warning.
