Dual-imaging technique useful before -- and during -- brain surgery
Brain specialists associated with the Neuroscience Institute at the University of Cincinnati (UC) and University Hospital say the ability to incorporate-in real time-two high-tech imaging tools into the operating room can improve the functional abilities of patients who undergo brain surgery.   view more (2007-06-11)

Molecular basis for neurodegeneration in Ataxia telangiectasia
An upcoming paper from Dr. David Wassarman (University of Wisconsin School of Medicine and Public Health) in the May 1 issue of G&D lends new insight into the pathogenesis of neurodegeneration in Ataxia telangiectasia.   view more (2008-04-15)

XMM-Newton reveals X-rays from gas streams around young stars
XMM-Newton has surveyed nearly two hundred stars under formation to reveal, contrary to expectations, how streams of matter fall onto the young stars' magnetic atmospheres and radiate X-rays.   view more (2007-06-01)

Gene changes linked to deficient immune suppression in MS
Oregon Health & Science University researchers have measured genetic changes reflecting a drop in the body's ability to suppress inflammatory cells that attack nerve fibers and promote progression of multiple sclerosis.   view more (2005-06-27)

Specialized white blood cells coordinate first responders to viral infection
Just as fire engines arrive quickly at the scene to save people and property, the cells that fight viruses have to reach the site of an infection promptly to mount a protective response.   view more (2008-04-25)

New model of p53 regulation proposed that suggests novel anticancer strategy
Genetically engineered mice convinced scientists at the Salk Institute for Biological Studies that it was time to overhaul widely held beliefs about how a powerful tumor suppressor called p53 is controlled in cells.   view more (2006-04-12)

New Evidence on How our Eyes use Light to Manage our Body Clock - University of Surrey Groundbreaking Study Results
A new study published this week shows for the first time that the human eye is sensitive to short wave length visible light and transmits information to the body clock in a way that may make it possible to manipulate waking and sleeping rhythms. This new data, gained from a study carried out at the... view more (2001-08-20)

Mental health intervention at school reduces PTSD among indonesian children affected by violence
A school-based intervention for children in communities affected by political violence in Indonesia reduced post-traumatic stress symptoms and helped maintain hope, but did not reduce traumatic stress-related symptoms, depressive symptoms, anxiety symptoms or functional impairment, according to a... view more (2008-08-13)

Vitamin D signals to prevent bone loss during osteoporosis
The risk of bone fracture resulting from falls increases as we age due to bone loss and osteoporosis. Physicians have routinely prescribed vitamin D and vitamin D-related drugs to retard bone loss, but until now, little was known about the specific targets of vitamin D in bone.   view more (2006-01-20)

Facial transplants are justified, say experts
With news of the world's first facial transplant hitting the headlines, experts in this week's BMJ debate whether the benefit of this procedure to someone with severe facial deformity outweighs the risk of long term suppression of the immune system.   view more (2005-12-09)

Chemotherapy and tamoxifen reduce risk of second breast cancer
Among breast cancer patients, both chemotherapy and tamoxifen independently reduced the risk of developing a second cancer in the other breast, according to a study published online December 25 in the Journal of the National Cancer Institute. The risk reduction persisted for at least 10 and 5... view more (2007-12-26)

Depression after unintended pregnancy is linked to abortion
Depression among women after an unintended first pregnancy is linked to whether they abort or carry to term, conclude researchers from the United States, in this week's BMJ.   view more (2002-01-16)

Reflecting on personal values offers protection from effects of stress, UCLA psychologists report
Reflecting on meaningful values provides biological and psychological protection from the adverse effects of stress, UCLA psychologists report in the November issue of the journal Psychological Science.   view more (2005-11-07)

Study shows Autism-related developmental 'red flags' identifiable at age two in children
Early detection of autism is critical for early intervention, yet autism spectrum disorders (ASD) are typically not diagnosed until after three years of age.   view more (2006-06-01)

Natural mechanism for immune suppression paves way for cancer trials
A natural mechanism pirated by tumors and HIV to evade the immune response is opening the door to better treatment for these conditions, researchers say.   view more (2007-03-29)

Music File Compressed 1,000 Times Smaller than MP3
Researchers at the University of Rochester have digitally reproduced music in a file nearly 1,000 times smaller than a regular MP3 file.   view more (2008-04-02)

Window of opportunity for restoring oaks small, new study finds
Communities of Oregon white oak were once widespread in the Pacific Northwest's western lowlands, but, today, they are in decline. Fire suppression, conifer and invasive plant encroachment, and land use change have resulted in the loss of as much as 99 percent of the oak communities historically... view more (2008-05-15)

Food for Flight: Monarch Butterfly Migration and Forest Restoration
USDA Forest Service (FS) research in the Ouachita Mountains of Arkansas suggests that decades of fire suppression have reduced the area's food supply for migrating monarch butterflies-and that restoration efforts that include prescribed burning can reverse this trend.   view more (2006-11-20)

Methadone Even at Therapeutic Levels Can Kill
Methadone is a possible cause of sudden cardiac death even when it isn't overdosed but is taken at therapeutic levels primarily for relief of chronic pain or drug addiction withdrawal, a new study by Oregon Health & Science University researchers suggests.   view more (2008-01-10)

Worm parasite may hold clues in bid for illness and allergy cures
Tiny worms that can trick the body's natural defences could hold the key to new treatments for a range of conditions, including diabetes, asthma and hay fever.   view more (2005-11-08)

Ritalin packs punch by elevating norepinephrine, suppressing nerve signal transmissions
Methylphenidate (Ritalin) elevates norepinephrine levels in the brains of rats to help focus attention while suppressing nerve signal transmissions in the sensory pathways to make it easier to block out extraneous stimuli, a Philadelphia research team has found.   view more (2006-05-30)

New research may show why some prostate cancer recurs after treatment
Cancer researchers have long worked to understand why some prostate cancers recur after the use of therapies designed to stop the production of testosterone and other androgens that fuel cancer cell growth.   view more (2007-10-12)

Hormone irregularities linked to chronic migraine
Hormonal irregularities may explain why migraine becomes chronic, shows research in the Journal of Neurology Neurosurgery and Psychiatry. Around 3 per cent of the population are chronic migraineurs, suffering pounding headaches for around 15 days a month. Hourly blood samples were taken from 17... view more (2001-11-23)

Separation from mom, dad linked with learning trouble in kids
In the wake of divorce, illness, violence and other problems that can unsettle homes, countless young children are liable to experience temporary separations from one or both parents before packing their knapsack for kindergarten.   view more (2008-05-16)

Parasite lipids against asthma or diabetes
Dutch research has demonstrated that lipids from the parasite schistosoma can inhibit human immune responses. This property makes the lipids interesting for a possible new treatment of diseases such as asthma and diabetes where the immune system responds inappropriately. During her doctoral... view more (2003-11-11)
