Star technology aids DNA analysis
University of Leicester astronomers and biologists have patented a new way of analysing DNA from gene-chips, which may be used in laboratories and hospitals to diagnose diseases from a single drop of blood and compare gene expression in different samples. The pioneering technique uses an instrument developed at the European Space Agency's... view more... (2003-11-03)

Early detection of Alzheimer's disease a possibility
Research investigating concentrations of magnetite, a magnetic form of iron, in Alzheimer's disease tissue has produced preliminary results that suggest the possibility of developing a technique to detect Alzheimer's disease before clinical symptoms appear. The research*, published in Biology Letters, an online supplement to the Royal Society's... view more... (2003-04-07)

People are unlikely to withdraw consent for genetic research
People are unlikely to withdraw consent for genetic research even when samples were taken many years ago, research in this week's BMJ suggests. In 1990 1583 randomly selected people in Sweden donated blood to a World Health Organisation project researching cardiovascular disorders and diabetes. Eleven years later, doctors sought their consent for... view more... (2002-09-18)
Household Exposure to Toxic Chemicals Lurks Unrecognized, Researchers Find
Although Americans are becoming increasingly aware of toxic chemical exposure from everyday household products like bisphenol A in some baby bottles and lead in some toys, women do not readily connect typical household products with personal chemical exposure and related adverse health effects. view more (2008-11-21)
DIAGNOSTIC TEST SHOULD LEAD TO BETTER CONTROL
A genetic test targeted at cattle could have a substantial impact in controlling sleeping sickness in east Africa, conclude authors of a fast-track study in this week's issue of THE LANCET. Sleeping sickness caused by Trypanosoma brucei rhodesiense (transmitted by the tsetse fly) is fatal if not treated. Drug treatment can be associated with... view more... (2001-12-12)
UC Davis study finds high arsenic levels in herbal kelp supplements
A study of herbal kelp supplements led by UC Davis public health expert Marc Schenker concludes that its medicinal use may cause inadvertent arsenic poisoning and health dangers for consumers, especially when overused. Schenker and two researchers evaluated nine over-the-counter herbal kelp products and found higher than acceptable arsenic levels... view more... (2007-04-09)

The report is available free online at www.liebertpub.com/ast view more (2008-08-14)
Free drug samples may burden patients' pockets
Following free drug sample receipt, patients who receive these samples have significantly higher out-of-pocket prescription costs than those who don't, according to the first study to look at the out-of-pocket cost associated with free-sample use. view more (2008-03-25)

New study raises questions about the number of people in the UK who could be incubating vCJD
A team of UK scientists found that 3 out of 12,674 stored appendix and tonsil samples showed evidence of the prion protein associated with vCJD, but urge caution about the way these results are interpreted. The research is published this week in The Journal of Pathology. The study aimed to help health policymakers estimate the numbers of people... view more... (2004-05-18)
Joint distraction promotes structural repair in patients with severe knee osteoarthritis
oint distraction (the use of a surgical frame around a degenerated joint to strengthen and promote repair) promotes cartilage repair in severe end stage osteoarthritis (OA) of the knee, as demonstrated for the first time by data presented today at EULAR 2008, the Annual Congress of the European League Against Rheumatism in Paris, France. view more (2008-06-16)
Pheromones Identified that Trigger Aggression between Male Mice
A family of proteins commonly found in mouse urine is able to trigger fighting between male mice, a study in the Dec. 6, 2007, issue of Nature has found. view more (2007-12-06)
Daily potassium citrate wards off kidney stones in seizure patients on high-fat diet
Children on the high-fat ketogenic diet to control epileptic seizures can prevent the excruciatingly painful kidney stones that the diet can sometimes cause if they take a daily supplement of potassium citrate the day they start the diet. view more (2009-07-22)
Methane found in desert soils bolsters theories that life could exist on Mars
Evidence of methane-producing organisms can be found in inhospitable soil environments much like those found on the surface of Mars. view more (2005-11-01)
Diamonds are a urologist's best friend
Wafer-thin coatings from diamond-like carbon can prevent dangerous biofilms of bacteria from forming on indwelling catheters in the urinary tract. What is more, the coated catheters glide into the ureter with considerably less friction, to the delight of medical staff, and even more so to that of the patients, who experience the procedure as... view more...

Unfavourable blood fat levels predict rheumatoid arthritis up to 10 years later
An unfavourable ratio of blood fats could herald the development of the inflammatory joint disease rheumatoid arthritis up to 10 years later, suggests research published ahead of print in the Annals of Rheumatic Diseases. view more (2006-06-05)
Testosterone, territoriality and the ‘home advantage’ in football
The `home advantage` is well known in football. The majority of teams in all divisions score more goals and win more games at home than away. Factors such as crowd support, referee bias, and familiarity with a venue, have been used to explain home advantage. New research presented today, Saturday 16 March, at The British Psychological Society... view more... (2002-02-27)
