Brain abnormalities in people who habitually lie

While previous research has shown that there is heightened activity in the prefrontal cortex - the area of the brain that enables most people to feel remorse or learn moral behavior - when normal people lie, this is the first study to provide evidence of structural differences in that area among pathological liars.

Compounds secreted by frog skin are potent blockers of HIV infection

The findings could lead to topical treatments for preventing HIV transmission, and they reinforce the value of preserving the Earth's biodiversity.

Potential beneficial effect of copper orotate

As one of the services for patients with Alzheimer's disease, the Department of Psychiatry at the Saarland University Medical Center offers participation in a clinical phase II trial. This clinical trial aims to elucidate a potential beneficial effect of copper orotate (an organic copper salt), which is given together with a standard cholinesterase inhibitor.

Speeding up fetal MRIs

A modified technique that uses the eyes as the line of reference means a 50 percent reduction in the time necessary to take MRI images of the fetal brain.

MRI may better enable physicians to plan care for infants with heart defects

Magnetic resonance imaging (MRI) techniques can provide real-time measurements of volume in a fetal heart, and may better enable physicians to plan care for infants with heart defects, according to a new study.

Alcoholics who smoke appear to lose more brain mass than alcoholics who don't smoke

It is already well-known that the brains of long-term alcoholics atrophy and shrink, the study authors say, but the new findings are the first evidence that cigarette smoking might contribute to that atrophy, particularly in grey matter of the parietal and temporal lobes.

Treatment of Nonalcoholic Fatty Liver Disease (NAFLD) in children

The Nonalcoholic Steatohepatitis (NASH) Clinical Research Network has launched its second clinical trial to study NASH, a liver disease that resembles alcoholic liver disease but occurs in patients who drink little or no alcohol. The first trial, launched in January of this year, focuses on adults, while the second trial studies the disease in children.

Recommendations for fellowship training in pediatric cardiology

The American College of Cardiology Foundation (ACCF), the American Heart Association (AHA), and the American Academy of Pediatrics (AAP) have joined forces to develop important first-ever recommendations for fellowship training in pediatric cardiology.

Digital mammography and breast cancer in older women

Digital mammography that uses computers to detect breast cancer found significantly (up to 28%) more cancers than screen film mammography in women 50 and younger, premenopausal and perimenopausal women, and women with dense breasts, according to results from one of the largest breast cancer screening studies ever performed.

Combining optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer

A new study shows that combining a technology called optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer from non-cancerous lesions--and potentially reduce the number of breast biopsies performed. The study appears in the October issue of the journal Radiology.

Still a long way to go in diagnostic evaluation of all patients who suffer ischemic strokes

Women who survive a stroke are less likely than men to get crucial tests of their heart and neck arteries that can help improve their treatment and reduce their risk of a second stroke, a new University of Michigan study finds.

Pulsing heart cell provides clues into how heart disease develops

A pulsing heart cell is giving Oregon Health & Science University researchers insight into how it sends and receives signals, and that's providing clues into how heart disease and other disorders develop.

Surprising immune system cells discovery

Immune system cells are connected to each other by an extensive network of tiny tunnels that, like a building's hidden pneumatic tube system, are used to shoot signals to distant cells.

Questionnaire helps identify women who have inherited genetic mutations that increase their risk for breast or ovarian cancer

A simplified way for patients to report and update their family medical histories could help identify women who have inherited genetic mutations that increase their risk for breast or ovarian cancer.

Israeli scientists successfully transplant ovaries in sheep and trigger early embryonic development

Israeli scientists report in Human Reproduction that they have successfully transplanted whole frozen and thawed ovaries in sheep, retrieved oocytes from these ovaries and triggered them in the laboratory into early embryonic development.

Neurologix announces positive interim results of gene therapy clinical trial for patients with Parkinson's disease

Neurologix has announced positive interim results of its landmark gene therapy clinical trial for patients with Parkinson's disease. Neurologix's 12-patient, dose-escalating Phase I trial is the world's first study to use a viral vector (the non-pathogenic adeno-associated virus, or AAV) for the treatment of an adult neurological disease.

PET brain scans of a brain chemical messenger system may prove sensitive enough to help plan brain surgery for epilepsy

When drugs fail to control epilepsy, brain surgery is often the only remaining therapeutic option. However, identifying the correct spot for surgery has traditionally required a separate preliminary -- and inherently risky -- surgical procedure.

Smaller prefrontal cortex is associated with early-onset drinking

Previous research has shown that alcohol-use disorders (AUDs) are associated with abnormalities of the prefrontal cortex, thalamus and the cerebellar hemispheres in adults.

First clinical guidelines to help improve the diagnosis and treatment of people with normal pressure hydrocephalus

An international team of medical experts led by a Virginia Commonwealth University researcher has established the first clinical guidelines to help improve the diagnosis and treatment of people with normal pressure hydrocephalus, a debilitating condition in the brain that often goes undiagnosed or is misdiagnosed as Alzheimer's or Parkinson's disease.
