ANN ARBOR, Mich.---Like bad neighbors who decide to go wreck another community, prostate and breast cancer usually recur in the bone, according to a new University of Michigan study.
Now, U-M researchers believe they know why. Prostate cancer cells specifically target and eventually overrun the bone marrow niche, a specialized area for hematopoietic stem cells, which make red and white blood cells, said Russell Taichman, professor at the U-M School of Dentistry and senior author of the study.
BETHESDA, Md., March 24, 2011 – We all know the adage: A little bit of a good thing can go a long way. Now researchers in London are reporting that might also be true for a large protein associated with wound healing.
Arthritis researchers from North America and Europe will convene in Chicago this week to present new osteoarthritis research that could lead to better ways to detect, treat, prevent and cure osteoarthritis (OA), which affects 27 million Americans. Hosted by the Arthritis Foundation, the Segal North American Osteoarthritis Workshop (SNOW) on March 25-27 will focus on specific forms of OA, such as those that follow joint trauma, obesity and the aging process.
MANHATTAN, Kan. -- A recently patented adhesive made by Kansas State University researchers could become a staple in every astronaut's toolbox.
The patent, "pH dependent adhesive peptides," was issued to the Kansas State University Research Foundation, a nonprofit corporation responsible for managing technology transfer activities of K-State. The patent covers an adhesive made from peptides -- a compound containing two or more amino acids that link together -- that increases in strength as moisture is removed.
Tel Aviv — When the Human Genome Project ended a decade ago, scientists thought that they'd closed the lid on all that's to be known about our genes. But what they really did was open a Pandora's Box, says theoretical evolutionary biologist Prof. Eva Jablonka of Tel Aviv University's Cohn Institute for the History and Philosophy of Science and Ideas.
The absence of specific laws which define the ownership, storage and use of blood drops taken from every Australian baby since 1971 could threaten public trust in newborn screening (NBS) programs in Australia, a University of Melbourne academic has warned.
International piracy costs the shipping industry billions of dollars a year and leads to high-profile murders that make global headlines. Longstanding concerns over piracy have led to numerous international laws and conventions designed to keep pirates in check – but research from North Carolina State University shows that the tangled network of laws may actually be helping pirates escape justice.
Men with high-risk prostate cancer who take statin drugs commonly used to lower cholesterol while receiving radiation therapy are less likely to have their cancer return than patients who do not take these medications, according to a study published in the March issue of the International Journal of Radiation Oncology•Biology•Physics, an official journal of the American Society for Radiation Oncology (ASTRO).
Using commercially available parts, U.S. Department of Agriculture (USDA) scientists and colleagues have developed a new automated system for detecting insects based on the peculiar sounds the insects make while moving.
According to entomologist Richard Mankin of USDA's Agricultural Research Service (ARS), one likely application will be to automate routine monitoring of industrial-scale traps, especially those placed in hard-to-reach areas like crawl spaces or near food processing equipment.
Chevy Chase, MD—Levels of the hormone ghrelin are low in obese women and a recent study accepted for publication in Endocrinology, a publication of The Endocrine Society, reports that mice whose mothers had low ghrelin levels were less fertile due to a defect in implantation.
ANN ARBOR, Mich. – Seemingly every year there are reports of a young, apparently healthy athlete dying on the court or playing field.
The sudden death of Wes Leonard, a junior at Fennville High School, who died of cardiac arrest from an enlarged heart on March 3, may have parents and coaches wondering if enough is being done to identify athletes at risk for dying suddenly.
According to UK government statistics over 8 million working days per year are lost due to illness and about a third of these are due to minor ailments such as coughs, colds, sickness and diarrhea. Yet two individuals who are equally ill do not necessarily both report sick. New research published in BioMed Central's open access journal BMC Public Health shows that conflicts and stress at work can trigger taking sick leave.
Published in the journal Royal Society Proceedings B: Biology, the brightly-coloured image shows the presence of amides – the organic compounds, or building blocks of life – in the ancient skin of a reptile, found in the 50 million year-old rocks of the Green River Formation in Utah, USA.
This image had never been seen by the human eye, until a team led by Dr Roy Wogelius and Dr Phil Manning used state-of-the-art infra-red technology at The University of Manchester to reveal and map the fossilized soft tissue of a beautifully-preserved reptile.
Public satisfaction with the NHS is at a record high, says John Appleby, Chief Economist at the King's Fund, in an article published on bmj.com today.
It follows a report in the Observer newspaper accusing England's Health Secretary Andrew Lansley of "burying" similar survey results because they undermine his case for urgent radical reforms.
A new trade agreement between India and Europe would block access to life saving drugs for billions of people living in developing countries, warns an expert on bmj.com today.
The EU wants India to adopt tough new patent protection rules for drugs so that no new generic drug could be sold in India without the permission of the company that owned the brand name version of the drug, writes James Love at Knowledge Ecology International in an editorial.
