Magnetic resonance imaging (MRI) is an imaging technique which physicians use for the diagnosis and treatment of medical conditions.

Enrollment commences in MINI-AMI study of Impella in STEMI patients

Abiomed, Inc., a leading provider of breakthrough heart support technologies, today announced the first patient enrolled in MINI-AMI, an FDA prospective, randomized, controlled multi-center study to assess the role of 24-hours of direct unloading of the left ventricle with Impella 2.5 support to reduce infarct size in patients with ST-elevation myocardial infarction (STEMI) without cardiogenic shock.

ALS damages neurons in parts of the brain responsible for cognition and behaviour

Recently published studies by a researcher in the Faculty of Medicine & Dentistry demonstrate that ALS - known as Lou Gehrig's disease - damages neurons in parts of the brain responsible for cognition and behaviour.

New insight into why some individuals may be more aggressive than others

Fluctuations of serotonin levels in the brain, which often occur when someone hasn't eaten or is stressed, affects brain regions that enable people to regulate anger, new research from the University of Cambridge has shown.

Researchers use MRI and PET/CT to assess safety, efficacy of heart drug dalcetrapib

Researchers from Mount Sinai School of Medicine have for the first time used several imaging techniques to prove the efficacy of a promising new treatment for atherosclerosis—the build-up of plaque in artery walls that can lead to a heart attack.

Women with BRCA gene mutation develop breast cancer earlier than their ancestors

Women with a deleterious gene mutation are diagnosed with breast cancer almost eight years earlier than relatives of the previous generation who also had the disease and/or ovarian cancer, according to new research from The University of Texas MD Anderson Cancer Center.

Cam impingement may increase risk of hip OA in young men

Hip impingement may be a risk factor of osteoarthritis (OA) of the hip. A new study reveals that the presence of an underlying deformity, known as cam impingement, is associated with hip damage in young men without any arthritis symptoms and detected using magnetic resonance imaging.

Study: K-complexes control effects of noise on sleep

During sleep, our perception of the environment decreases. However the extent to which the human brain responds to surrounding noises during sleep remains unclear. In a study published this week in Proceedings of the National Academy of Sciences (PNAS), researchers from University of Liège used brain imaging to study responses to sounds during sleep.

Stroke in the young on the rise: Study

A new study has revealed that more children and young adults in the U.S. are having strokes. Researchers speculate that unhealthy lifestyles could be a likely contributor.

Princeton researchers match images of brain activity with complex thought

In an effort to understand what happens in the brain when a person reads or considers such abstract ideas as love or justice, Princeton researchers have for the first time matched images of brain activity with categories of words related to the concepts a person is thinking about. The results could lead to a better understanding of how people consider meaning and context when reading or thinking.

New study pinpoints areas of the brain used exclusively for language

New research from MIT suggests that there are parts of our brain dedicated to language and only language, a finding that marks a major advance in the search for brain regions specialized for sophisticated mental functions.

Intra-aortic balloon counterpulsation prior to PCI does not reduce infarct size in AMI patients

Inserting intra-aortic balloon pumps prior to angioplasty in patients with acute myocardial infarction (AMI) does not reduce the scope of heart muscle damage, a condition referred to as infarct size, according to a new study conducted by Duke University Medical Center researchers.

Magnetic resonance imaging may predict survival in patients with advanced rectal cancer

A new study has shown that magnetic resonance imaging (MRI) used to evaluate responses to pre-surgery (neo-adjuvant) chemotherapy or radiation may predict survival among patients with advanced rectal cancer.

Scientists discover nanoparticles can disrupt intracellular transport pathways

Scientists at the Centre of Cancer Biomedicine at the Norwegian Radium Hospital are the first to show that uptake and accumulation of nanoparticles in cells can disrupt important intracellular transport pathways.

Risk of depression in formerly depressed people

Depression is increasingly recognized as an illness that strikes repeatedly over the lifespan, creating cycles of relapse and recovery. This sobering knowledge has prompted researchers to search for markers of relapse risk in people who have recovered from depression. A new paper published in Elsevier's Biological Psychiatry suggests that when formerly depressed people experience mild states of sadness, the nature of their brains' response can predict whether or not they will become depressed again.

Babies of mothers with higher pre-pregnancy BMI are fatter, finds study

Babies of mothers with a higher pre-pregnancy body mass index (BMI) are fatter and have more fat in their liver, a study published in September's issue of the journal Pediatric Research has found.

Study: Eye contact seems to act as an invitation for mimicry

Imitation may be the sincerest form of flattery but how do our brains decide when and who we should copy? Researchers from The University of Nottingham have found that the key may lie in an unspoken invitation communicated through eye contact.

Study tracks development of chimp brain and makes comparison to humans

In both chimpanzees and humans, portions of the brain that are critical for complex cognitive functions, including decision-making, self-awareness and creativity, are immature at birth. But there are important differences, too. Baby chimpanzees don't show the same dramatic increase in the volume of prefrontal white matter in the brain that human infants do.
