Researchers at the University of Leicester have demonstrated that movable sequences of DNA, which give rise to genetic variability and sometimes cause specific diseases, are far more common than previously thought.
In a paper published in the leading journal Cell, Dr Richard Badge and his collaborators examined L1 (or LINE-1) retrotransposons: DNA sequences which can 'copy and paste' their genetic code around the genome. By breaking up genes, L1s can be responsible for some rare instances of genetic disease.
Rome, Italy: The first worldwide study of the societal impact of endometriosis has found a significant loss of work productivity among those women who suffer from the condition, a researcher told the 26th annual meeting of the European Society of Human Reproduction and Embryology today (Monday). Dr. Kelechi Nnoaham, from the Department of Public Health, University of Oxford, UK, said that the results of this multi-centre study would help highlight the previously unrecognised plight of an estimated 176 million women around the world whose lives are affected by endometriosis.
Scientists from the University of Warwick and University Hospitals Coventry and Warwickshire NHS Trust, are the first to directly measure a specific region of DNA in human embryos. The length of this region could be a quality marker for embryonic development.
AUGUSTA, Ga. – A tooth-bleaching agent may improve the oral health of elderly and special-needs patients, say dentists at the Medical College of Georgia and Western University of Health Sciences.
BUFFALO, N.Y. -- Vietnam War-era veterans exposed to Agent Orange appear to have significantly more Graves' disease, a thyroid disorder, than veterans with no exposure, a new study by endocrinologists at the University at Buffalo has shown.
Ajay Varanasi, MD, an endocrinology fellow in the UB Department of Medicine and first author on the study, garnered first prize in the oral presentation category for this research at the American Association of Clinical Endocrinologists annual meeting held in Boston in April.
A new study published online today by JAMA shows that among patients age 65 years and older, rosiglitazone (a medication for treating Type 2 diabetes) is associated with an increased risk of stroke, heart failure, and all-cause mortality (death) when compared with pioglitazone (another medication for diabetes). The study was published online today in advance of an upcoming Food and Drug Administration meeting that will review the safety of rosiglitazone. The paper will appear in the July 28 print issue of JAMA.
Eleven years after the introduction of the diabetes drug rosiglitazone, data from available clinical trials demonstrate an increased risk for heart attack associated with its use and suggest an unfavorable benefit-to-risk ratio, according to a report posted online today that will appear in the July 26 print issue of Archives of Internal Medicine, one of the JAMA/Archives journals. The study was published online in advance of an upcoming Food and Drug Administration meeting that will review the safety of rosiglitazone.
NEW YORK, June 27, 2010 – Researchers funded by JDRF have discovered that the hormone, serotonin, may be involved in the increase of insulin-producing beta cells during pregnancy. The findings reveal one of the mechanisms underlying beta cell expansion during pregnancy, and are the latest advances underscoring the potential for regeneration as a key component of a possible cure for type 1 diabetes.
In Japan, the hon-shimeji mushroom is a delicacy costing up to SEK 8,000 a kilo (800 Euro). Now a student at the University of Gothenburg, Sweden, has discovered that this tasty fungus also grows wild in Sweden.
"There will undoubtedly be a lot of interest in Sweden, and definitely in Japan once these discoveries become known there," says Henrik Sundberg, who conducted the study.
Bees could have a key role to play in urgently-needed new treatments to fight the virulent MRSA bug, according to research led at the University of Strathclyde in Glasgow, Scotland.
The scientists found that a substance known as beeglue or propolis, originating from beehives in the Pacific region, was active against MRSA, which causes potentially fatal infections, particularly in hospital patients.
The bug was either the underlying cause or a contributory factor in more than 1,900 deaths between 1996 and 2008.
28 June 2010 [Vienna, Austria] – Three leading scientific and health policy organizations today launched a global drive for signatories to the Vienna Declaration (www.viennadeclaration.com), a statement seeking to improve community health and safety by calling for the incorporation of scientific evidence into illicit drug policies. Among those supporting the declaration and urging others to sign is 2008 Nobel Laureate and International AIDS Society (IAS) Governing Council member Prof.
Neuherberg, Düsseldorf, June, 28. 2010. An international consortium including Helmholtz Zentrum München and the German Diabetes Center, Düsseldorf has identified 12 new gene variants which impact the individual's risk of developing type 2 diabetes. The study represents a major contribution towards elucidating the complex pathogenesis of this important widespread disease. Nature Genetics has published the findings of this study in its current issue.
For people with hypertension, eating dark chocolate can significantly reduce blood pressure. Researchers writing in the open access journal BMC Medicine combined the results of 15 studies into the effects of flavanols, the compounds in chocolate which cause dilation of blood vessels, on blood pressure.
How tall can a tree grow? Does sunlight or water limit the size and photosynthetic capacity of a leaf? Could constraints on leaf growth really determine the height of a tree? These are all questions that Alana Oldham of Humboldt State University, CA, was eager to answer as she and her colleagues dangled from an ancient redwood tree well over a football field's length in height above the ground.
