Smoking damages the placenta and reduces foetal growth
Dr Peter Hindmarsh (University College, London), at the British Endocrine Societies 2003 meeting, will reveal new evidence that smoking when pregnant causes damage to the placenta and reduced birth weight. His team found that nutrient delivery to the baby was restricted and levels of an important developmental hormone, IGF-1, were reduced, causing... view more... (2003-03-19)
Screening to help prevent stroke in kids increases, but limited access a problem
The number of children with a certain blood disorder undergoing an ultrasound to help prevent stroke is up significantly in the past 10 years since the publication of a major study showing its benefits. view more (2009-04-14)
Insulin sensitizer also serves as energy-conserving signal to the brain
A fat-derived protein known for its effects on the liver and skeletal muscle might also serve as an energy-conserving signal to the brain during periods of starvation. view more (2007-07-11)
Cancer drug can extend survival in patients with deadly brain tumors
Avastin, a relatively new type of drug that shrinks cancerous tumors by cutting off their blood supply, can slow the growth of the most common and deadly form of brain cancer, a pilot study conducted at Duke University Medical Center has found. view more (2007-02-20)
Cellular cues identified for stroke recovery
When a stroke strikes, the supply of blood to the part of the brain affected is interrupted, starving it of oxygen. Brain cells can be seriously damaged or die, impairing local brain function. view more (2006-12-26)
Alzheimer's disease; new approach, new possibilities?
Scientists from the Flanders Interuniversity Institute for Biotechnology (VIB) associated with the University of Antwerp have achieved a new breakthrough in their research on the origins of Alzheimer's disease. view more (2005-07-28)
Statin treatment may curb Alzheimer's brain changes
People who take statin drugs may be less likely to develop the brain changes that signal Alzheimer's disease, according to a study published in the August 28, 2007, issue of Neurology(r), the medical journal of the American Academy of Neurology. view more (2007-08-28)
CSIRO imagery shows outer Great Barrier Reef at risk from river plumes
A stunning series of satellite imagery of Australia's Great Barrier Reef released by the CSIRO shows for the first time visual confirmation of the theory that sediment plumes travel to the outer reef, and beyond. view more (2007-02-28)
Research finds older women who are more physically fit have better cognitive function
New research published in the international journal Neurobiology of Aging by Marc Poulin, PhD, DPhil, finds that being physically fit helps the brain function at the top of its game. view more (2009-01-09)
MIT material stops bleeding in seconds
MIT and Hong Kong University researchers have shown that some simple biodegradable liquids can stop bleeding in wounded rodents within seconds, a development that could significantly impact medicine. view more (2006-10-10)
Animal Study Identifies Promising New Target for Brain Tumor Therapy
A drug that targets the body's immune cells may be effective in treating malignant brain tumors, according to a new study led by researchers at Duke's Preston Robert Tisch Brain Tumor Center. In animal models, the drug re-engaged the body's cancer-damaged immune system. view more (2007-05-09)
Brain plays key role in diabetes therapy
The brain plays a major role in the ability of insulin therapy to lower blood sugar in animals with diabetes. view more (2006-01-11)
Oxygen deprived brains repaired and saved
Scientists from Melbourne's Howard Florey Institute have found special proteins that protect the brain after it has been damaged by a lack of oxygen, which occurs in conditions such as stroke, perinatal asphyxia, near-drowning and traumatic brain injury. view more (2006-08-25)
Reef Sharks Threatened by Overfishing
A study by Australian scientists has warned that coral reef shark populations on the Great Barrier Reef are in the midst of a catastrophic collapse. view more (2006-12-06)
Common cold virus came from birds
A virus that causes cold-like symptoms in humans originated in birds and may have crossed the species barrier around 200 years ago, according to an article published in the December issue of the Journal of General Virology. Scientists hope their findings will help us understand how potentially deadly viruses emerge in humans. view more (2008-11-20)
Brain tumor researchers find their 'niche'
Brain tumors appear to arise from cancer stem cells (CSCs) that live within microscopic protective "niches" formed by blood vessels in the brain; and disrupting these niches is a promising strategy for eliminating the tumors and preventing them from re-growing. view more (2007-01-17)
There goes the neighborhood: Vascular niche nurtures brain tumor stem cells
Self-renewing cancer stem cells (CSCs) comprise only a tiny fraction of most brain tumors, but eliminating them is likely to have a profound impact on the ability of a tumor to survive and grow. view more (2007-01-17)
Stealth particles to target tumors
Stealth nano particles may some day target tumor cells and deliver medication to specific body locations, according to Penn State chemical engineers. view more (2005-09-01)
UT Southwestern study shows how substance in grapes may squeeze out diabetes
A naturally produced molecule called resveratrol, found in the skin of red grapes, has been shown to lower insulin levels in mice when injected directly into the brain, even when the animals ate a high-fat diet. view more (2009-10-15)
Possible new compound for treatment of cerebral malaria
In a paper published online in PLoS Medicine researchers from Marseille describe the effects of a new compound that may be a future treatment for patients with cerebral malaria. view more (2005-08-23)
