Scans show hysteria is caused by a brain dysfunction

Hysteria is an unexplained neurological disorder in which a patient complains of symptoms, ranging from numbness in a limb, to paralysis, memory loss and seizures, that cannot be traced to any known medical problem and doctors fail to find anything medically wrong with them.

Vascular targeted nanoparticles for imaging and treatment of brain tumors

Combining two promising approaches to diagnosing and treating cancer, a multidisciplinary research team at the University of Michigan has created a targeted multifunctional polymer nanoparticle that successfully images and kills brain tumors in laboratory animals.

Elasticity imaging could alleviate need for biopsies

A noninvasive technique to visualize soft tissue stiffness allows radiologists to accurately distinguish benign from malignant breast lesions.

High dopamine transporter levels not linked to attention-deficit hyperactivity disorder

Results from a brain-imaging study conducted at the U.S. Department of Energy's Brookhaven National Laboratory in collaboration with Mount Sinai School of Medicine in New York indicate that levels of a brain protein proposed as a diagnostic marker for attention-deficit hyperactivity disorder (ADHD) are not positively correlated with the disease.

Violent video games have an effect on kids brains

A new study has found that teenagers who play violent video games have increased activity in those areas of the brain which control emotional arousal, and decreased activity in the regions associated with control, focus and concentration.

Cone Beam Computed Tomography could make mammogram agony a thing of the past

A new breast scan process promises to make the annual mammogram agony many women endure a thing of the past.

An aching back? Well don't sit up straight!

By using a new form of magnetic resonance imaging (MRI), Scottish and Canadian researchers have been able to show that sitting in an upright position places unnecessary strain on the back.

Summary of FDA's approval of silicone breast implants

Two editorials respond to FDA's approval on Friday of the use of silicone breast implants manufactured by Santa Barbara, Calif.-based Mentor and Irvine, Calif.-based Allergan for breast reconstruction and cosmetic breast augmentation.

Watching a tumor cell migrate

Using a microfluidics device designed to reproduce the physical microenvironment of small blood vessels and the spaces between cells, researchers at the National University of Singapore have imaged single tumor cells deforming as they migrate through the device.

HRT shows promise in helping visual memory of postmenopausal women

Many women experience declines in their memory during and after menopause, a change thought to be due, in part, to the rapid hormonal changes they weather during that time.

Cause of exercise intolerance in heart failure patients

A new study shows that blood flow to the legs is relatively normal in people with diastolic heart failure, suggesting other potential causes of their inability to do everyday activities, according to researchers at Wake Forest University Baptist Medical Center.

Proteins may behave differently in natural environments

When in an environment similar to that in which they exist naturally, proteins and multiprotein assemblies may demonstrate actions or dynamics different than those they exhibit when in the static form in which they are most often studied, said researchers at Baylor College of Medicine in a report in the current issue of the journal Structure.

Waltzing is the way to mend a broken heart!

Italian researchers have found that in patients recovering from heart attacks dancing the waltz was as effective as routine training programs for improving heart health.

Research sheds light on episodic memory

Memories of events comprise many components--including sights, sounds, smells, and tastes. Somehow the many features of an episodic memory are woven together into a coherent whole, and researchers have had little understanding of how this binding takes place as the memories are processed by the brain's memory center, the hippocampus.

Shaped-beam radiosurgery treats tiniest lung tumors

Patients with metastatic cancer tumors in their lungs are much more likely to live disease-free if they have an experimental treatment involving shaped-beam radiosurgery rather that conventional treatment, according to a University of Rochester Medical Center study.

Researchers show brain injury may occur within one millisecond after head hits windshield

Research by a Sandia National Laboratories engineer and a University of New Mexico Health Sciences Center neurologist shows that brain injury may occur within one millisecond after a human head is thrust into a windshield as a result of a car accident.

MRI technology breaks new ground in molecular imaging

Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have developed a new technique for magnetic resonance imaging (MRI) that allows for detection of signals from molecules present at 10,000 times lower concentrations than conventional MRI techniques.
