Like salty food? Chances are you had low blood sodium when you were born

...index of sodium loss. The latter was determined by screening all the serum sodium measurements of each infant's postnatal medical record, and selecting the lowest. Each child underwent a pediatric physical examination. To estimate current sodium appetite, participants were tested for their preferred concen...

NIH announces phase III clinical trial of creatine for Parkinson's disease

...inson’s researchers through a new rapid method for screening potential compounds. The double-blind, placebo-controlled, phase III study is one of the largest PD clinical trials to date. It will enroll 1720 people with early-stage PD at 51 medical centers in the United States and Canada. "This study is an ...

Using dental X-rays to detect osteoporosis

...victim at least once in their lifetime. Wide-scale screening for the disease is not currently viable, largely due to the cost and scarcity of specialist equipment and staff. The team has therefore developed an innovative software-based approach to detecting osteoporosis using routine dental x-rays, by automa...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

The database will be distributed through the computational data grid, and accessible through web portals mirrored at partner s...

Anti-fungal drug stops blood vessel growth

...l drugs had much lower inhibitory effect. “Our screening test did show that cholesterol-lowering statins also appear to stop blood vessel growth,?Liu says, “so there is likely some important connection between cholesterol and angiogenesis.? While the researchers still must tease out exactly how itracona...

Growth hormone to boost athletic performance risks diabetes

...t is easy to buy online and difficult to detect in screening tests—unlike anabolic steroids. The authors believe that this is the first reported case of diabetes associated with the use of high dose growth hormone, and urge anyone taking high doses to regularly check their blood sugar levels....

Colour sensor breath test can detect lung cancer

Researchers show that veins stiffen as we age

...nd 70 years old. Each individual underwent medical screening at Christiana Hospital, which included a lipid profile, blood pressure monitoring, electrocardiogram and several other tests to ensure overall good health. Then each participant was involved in a series of research trials at UD's Human Performance ...

These developments have reduced the cost, time, and space needed to carry out structural studies, as well as impro...

Transplanted brain cells hold promise for Parkinson's disease

...se process, which rarely happens since there is no screening test to catch it early. "Right now we are saying if you are able to identify Parkinson’s in the early stage, we think this therapy will work. An important question that remains is, ‘Can we rescue neurons that are dying from Parkinson’s"?This woul...

Hair-growth drug artificially lowers PSA levels in prostate cancer screening, study finds

The study, involving 308 men ranging in age from 40 to 60 years old, is available online in the British medical journal The Lancet and is scheduled to be published after Jan. 1, 2007. The stu...

Common ancestry of bacterium and plants could be key to an effective new treatment for chlamydia

... a new antibiotic is on. Leustek is going to start screening for chemicals that block the enzyme. He is also using the results of his research to work on another approach, which is to characterize the structure of the enzyme so that he could design an antibiotic that would disable the pathway. This approach is...

Natural anti-viral enzyme helps keep cancer cells alive, researchers find
