Scientist finds different paths lead to similar cognitive abilities

Despite the divergent evolutionary paths of dolphins and primates -- and their vastly different brains -- both have developed similar high-level cognitive abilities, says Emory University neuroscientist and behavioral biologist Lori Marino.

How heart is formed in the embryo helps explain congenital heart disease

Children's Hospital of Pittsburgh Cardiologist Bradley B. Keller, MD, and his research team are discovering details in the lab that explain how the heart is formed in the embryo. This knowledge improves the chances of doctors identifying fetuses who can benefit from intervention to treat congenital defects.

Genomics and proteomics to increase the efficiency of drug discovery and development

While the United Sates is still the world leader, Europe is having a good deal of success in the field of advanced genomics and proteomics research. Significant government funding together with the presence of large pharmaceutical companies has made Europe a major competitor in the efforts to deploy genomics and proteomics as vital tools in drug discovery and development.

Immune cells in the liver travel in the liver's blood vessels with surprising speed and agility

Scientists at New York University School of Medicine viewing the actual journey of immune cells in the liver have found that these cells travel in the liver's blood vessels with surprising speed and agility.

Newer imaging technologies may lead to over treatment

Newer imaging technologies allow physicians to visualize more of the arteries in the lungs, including detecting small blood clots not previously seen, but seeing more may have little impact on the patient’s outcome, a new study suggests.

New antipsychotic drug prevents brain loss in schizophrenia

A new brain imaging study of recently diagnosed schizophrenia patients has found, for the first time, that the loss of gray matter typically experienced by patients can be prevented by one of the new atypical antipsychotic drugs, olanzapine, but not by haloperidol, an older, conventional drug.

Chemoembolization, first-line treatment for liver cancer

New research by Jeff Geschwind, M.D., director of interventional radiology and associate professor at Johns Hopkins University School of Medicine, has shown that liver cancer patients, most of whom have inoperable tumours, could benefit from chemoembolization, a nonsurgical treatment option that delivers a high-dose of chemotherapy to the tumour while decreasing blood flow through the arteries feeding the tumour, known as embolization.

Study shows connection of varicose veins to chronic pelvic pain

Research presented today at the Society of Interventional Radiology's 30th Annual Scientific Meeting found that 16 percent of women with varicose veins in their legs simultaneously had ovarian varicose veins -- a common but often under-diagnosed cause of chronic pelvic pain.

Different antipsychotic medications may have different effects on brain volume in patients with first episode of psychosis

After a first psychotic episode, patients who were treated with an atypical antipsychotic medication had less change in brain volume compared with patients treated with a conventional antipsychotic medication, according to an article in the April issue of Archives of General Psychiatry.

Brain region recovery possible in former methamphetamine users

Adaptive changes in chemical activity in certain regions of the brain of former methamphetamine users who have not used the drug for a year or more suggest some recovery of neuronal structure and function, according to an article in the April issue of Archives of General Psychiatry.

Uterine fibroid embolization is effective treatment for uterine fibroids

Data presented today at the 30th Annual Scientific Meeting of the Society of Interventional Radiology found that the nonsurgical embolization treatment for uterine fibroids had a 73 percent success rate at five years.

Finding opens new doors to determining susceptibility to antidepressant side effects

In a finding that opens new doors to determining susceptibility to antidepressant side effects, researchers at the UCLA Neuropsychiatric Institute report that changes in brain activity prior to treatment with antidepressants can flag patient vulnerability.

Clinical study of mirror neurons provides insights into autism and other disorders

Seeing is doing – at least it is when mirror neurons are working normally. But in autistic individuals, say researchers from the University of California, San Diego, the brain circuits that enable people to perceive and understand the actions of others do not behave in the usual way.

Optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques

A catheter-based imaging technology called optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques in patients with various cardiac symptoms. The report from researchers at Massachusetts General Hospital (MGH) will appear in the journal Circulation.

DNA sequencing made portable and faster by "colour-blind" technology

Researchers at Baylor College of Medicine (BCM) and Rice University have developed a"colour-blind" method of fluorescence detection which could open new doors that would take DNA sequencing to the patient's bedside, the doctor's office and even the scene of a crime or a battlefield.

Left-right brain mystery - trail is hot and cold

Australian National University (ANU) researchers have developed a new device that could potentially unravel the mysteries of the left and right brain by measuring ear temperature.

Diffusion MRI gives early indication if brain cancer therapy is effective

A special type of MRI scan that measures the flow of water molecules through the brain can help doctors determine early in the course of brain cancer regimen if a patient's tumor will shrink, a new study shows.

Ultrafast laser detection of cancer cells also may improve understanding of stem cells

To investigate tumors, pathologists currently rely on labor-intensive microscopic examination, using century-old cell-staining methods that can take days to complete and may give false readings.

Evidence of cross-activation in brain regions of people who see letters and numbers in colors

Synesthesia, a condition characterized by one sensory experience generating another – so that shapes have tastes, for instance – is estimated to affect between 1 in 200 to 1 in 2,000 people. The most common form involves seeing specific letters or numbers (graphemes) in specific colors.

Preventing eye disease in retinitis pigmentosa

Retinitis pigmentosa (RP) is an inherited eye disease that causes visual disability leading to blindness. Over the last 15 years, researchers have pinpointed defects in dozens of genes causing different forms of RP.
