NEJM study finds drug-eluting stents more effective than bare-metal stents in heart attack patients
NewYork-Presbyterian Hospital and Columbia University Medical Center, together with the Cardiovascular Research Foundation (CRF), announced that its landmark study comparing the safety and efficacy of drug-eluting stents and bare-metal stents was published in the May 7 New England Journal of Medicine. view more (2009-05-27)
Larger skin lesions appear more likely to be melanomas
Skin lesions larger than 6 millimeters in diameter appear more likely to be melanomas than smaller lesions, according to a report in the April issue of Archives of Dermatology, one of the JAMA/Archives journals. The findings suggest that the diameter guidelines currently used by dermatologists to screen for melanoma are useful. view more (2008-04-22)
Master planners in brain may coordinate other areas' roles in cognitive tasks
Scientists have used data from scans of 183 subjects to identify brain areas that consistently become active in a variety of cognitive tasks, such as reading, learning a rhythm or analyzing a picture. view more (2006-06-01)
Computer obeys thoughts via Brain-Computer Interface
A research group led by Academy Professor Mikko Sams is developing a brain-computer interface, a device that transforms electrical or magnetic brain signals into commands a computer can understand. Equipment of this kind is necessary. For instance, it enables physically disabled persons to use a computer keyboard. The Brain-Computer Interface, or... view more... (2005-03-02)
A genetic factor predicts prognosis in brain tumor patients
PLoS ONE has just published a study which defines a gene locus on chromosome 1 that predicts prognosis of brain tumor patients and may even set the basis for the development of more efficient drugs to combat brain cancer. view more (2007-06-28)
Why the brain has 'gray matter'
By borrowing mathematical tools from theoretical physics, scientists have recently developed a theory that explains why the brain tissue of humans and other vertebrates is segregated into the familiar "gray matter" and "white matter." view more (2006-01-12)
18F-DG PET/CT can highly increase the detection of colorectal cancer
Combined positron emission tomography and computed tomography (PET/CT) is currently widely used in the clinical diagnosis of cancer to provide functional and morphological imaging. view more (2007-10-11)
MRI scans in premature infants can predict future developmental delays
A Washington University pediatrician at St. Louis Children's Hospital has found that performing MRI scans on pre-term infants' brains assists dramatically in predicting the babies' future developmental outcomes. view more (2006-08-17)
During exercise, the human brain shifts into high gear on 'alternative energy'
Alternative energy is all the rage in major media headlines, but for the human brain, this is old news. According to a study by researchers from Denmark and The Netherlands published in the October 2008 print issue of The FASEB Journal, the brain, just like muscles, works harder during strenuous exercise and is fueled by lactate, rather than... view more...

Finding out which parts of the brain do what
Ever since the Greeks proposed that different parts of the brain housed different parts of the ‘soul’, mankind has tried to discover where our mental functions are located. This evening, Thursday 22 February, in a public lecture at the Royal Society, 6 Carlton House Terrace, London SW1Y 5AG, Professor Alan Cowey FRS of the University... view more... (2001-02-15)
Mind over matter: SH2B1 in the brain regulates obesity
Obesity is one of the main risk factors for developing type II diabetes. Previous studies have shown that mice lacking a protein known as SH2B1 throughout their body are obese and develop diabetes. view more (2007-01-19)
Software enhancement of breast MRI scans help radiologists reduce false positives
Using commercially available software to enhance breast scans done by magnetic resonance imaging (MRI) reduces the number of false positive identifications of malignant tumors and the subsequent need for biopsies. view more (2007-06-25)
New Technique For Measuring Blood Flow To Brain In Babies (p 1749)
Authors of a research letter in this week's issue of THE LANCET describe how an ultrasound technique can be used as a non-invasive way of measuring blood flow to the brain in babies, which may be of benefit to infants with brain disorders arising from restrictions in cerebral blood flow. Changes in the rate of blood flow to the brain in premature... view more... (2002-11-27)
Bigger brain size matters for intellectual ability
Brain size matters for intellectual ability and bigger is better, McMaster University researchers have found. view more (2005-12-23)
Hold your horses
For those who suffer with the debilitating symptoms of Parkinson's disease, Deep Brain Stimulation offers relief from the tremors and rigidity that can't be controlled by medicine. view more (2007-10-26)
Obstructive sleep apnea patients show silent brain infarction lesions
Patients with moderate to severe sleep apnea who have significantly higher serum levels of inflammatory markers that serve as precursors to coronary artery disease, as well as lesions associated with silent brain infarction, have an elevated risk of stroke, according to a group of Japanese medical researchers. view more (2007-03-15)
New brain cells listen before they talk
Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells-a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or neurodegeneration, Yale School of Medicine... view more...

Is brain size linked to two common gene variants?
Human brain size is hereditary, but the genes that influence brain size in healthy people are unknown. view more (2006-05-17)
Family history of brain tumors linked to increased risk of brain cancer
People with a family history of cancerous brain tumors appear to be at higher risk of developing the same kind of tumors compared to people with no such family history. view more (2008-09-22)
Delusions associated with consistent pattern of brain injury
A new study provides a novel theory for how delusions arise and why they persist. NYU Langone Medical Center researcher Orrin Devinsky, MD, performed an in-depth analysis of patients with certain delusions and brain disorders revealing a consistent pattern of injury to the frontal lobe and right hemisphere of the human brain. view more (2009-01-14)
