Ibruprofen and other commonly used painkillers for treating inflammation may increase the risk of heart attack

...as added to this combination, it produced clinical features of invasive human melanoma: darkly pigmented skin that progressed to ulcerated tumor nodules. Melanoma was observed as early as one month after the oncogenic combination was introduced. The tumors demonstrated aggressive local invasion but did not m...

Engineered skin offers clues to melanoma development

...as added to this combination, it produced clinical features of invasive human melanoma: darkly pigmented skin that progressed to ulcerated tumor nodules. Melanoma was observed as early as one month after the oncogenic combination was introduced. The tumors demonstrated aggressive local invasion but did not m...

Beauty queens urge girls not to sacrifice their bones

...elebrated worldwide on October 20, which this year features the theme "Move it or Lose it" - the role of exercise in building strong bones". The theme for World Osteoporosis Day 2006 will be "Bone Appetit-the importance of nutrition in bone health". Osteoporosis, in which the bones become fragile and break ...

Scientists discover stem cell origin of neck and shoulders

... trace what happened to a major shoulder bone that features in many extinct land animals. They found that it appears to survive in modern vertebrates as the scapular spine. Dr Koentges commented, "Now that we have identified these key players in forming the neck and the shoulders we can start looking for the...

Achilles heel of the herpes virus possibly found

...new papers show that the B5 receptor has important features that could explain why it is important to HSV's ability to fuse with the fluid membrane that encloses every human cell. The researchers were able to show that by placing only the DNA sequence that encodes B5 into HSV-resistant pig cells, they could m...

A whole lot of shaking goin' on triggers early hatching in red-eyed tree frogs

...s." To test the hypothesis that embryos use these features of vibrations to assess danger, Warkentin clumped the rain recordings together into tightly spaced segments, making them more snake-like. Conversely, she spliced bits of stillness into the snake vibrations, making them more rain-like. When snake-like...

Researchers grow stem cells from human skin

...ional molds and implanted in mice, they maintained features consistent with bone, muscle and fat tissue. "Our study shows that stem cells can be obtained from a simple skin biopsy and can be made to become three vital tissues," said Shay Soker, Ph.D., associate professor of surgery at Wake Forest's School of ...

Chickadees can help humans get their bearings

... all previously tested animals by ignoring angular features of their environment and following landmarks instead. Although able to learn geometry when guiding themselves to food in lab experiments, the birds consistently ignored the concept when a prominent landmark, in this case a blue wall, was present. "G...

Unique library of plant genes germinates, takes root at UNC

... know so much about. "We will continue to add new features to Phytome over the next few years," Vision said. "Perhaps the most important will be the ability to compare the genetic maps of multiple species simultaneously and predict the gene content in regions of plant genomes that have not yet been deciphere...

Researchers reveal secrets of flying snakes

... in August 2002, Socha described a few aerodynamic features of the paradise tree snake -- one of five snake species that are purported to "fly." He videotaped and photographed various snakes taking off from a 33-foot-high tower in an open field at the Singapore Zoological Gardens. He positioned two video came...

Atmosphere may cleanse itself better than previously thought

... systems of interest frequently have weak spectral features there, so they're tough to see," said Francisco, who contributed the study's computations. "The upshot is that a lot of atmospheric models ignore this region altogether, assuming that because nothing can be seen, nothing must be happening." The lase...

A probe, not an echo

... to 2 mm for the best alternatives). Several other features promise to make the technology a scientific and cl... improved resolution, the system can locate tissue features with extreme precision in a objective, fixed-coordinate 3D grid, crucial for guiding surgical proced...

DOE JGI launches IMG public online microbial genome data clearinghouse

...other single institution. The IMG system currently features over 200 organisms, with an additional 200 already in the queue for 2005. The release of IMG, accessible to the public at http://img.jgi.doe.gov/, is the result of a collaboration between the DOE JGI and Lawrence Berkeley National Laboratory's Biolog...

Next Generation Body Scanner Launched By The University Of Manchester

...s been manufactured by Philips Medical Systems and features a 5.5 tonne magnet, will be launched by Professor Colin Blakemore, Chief Executive of the Medical Research Council and Professor Alan Gilbert, President and Vice Chancellor of The University of Manchester - see EDITORS NOTES for further details.

AIDS Public Awareness Campaign Expands Following Report Of Rapidly Progressive HIV

... one's HIV status and getting tested. The campaign features television promotions with national celebrities, including Alicia Keys. The initiatives announced today build on the public awareness efforts now underway in New York. The Department is currently running a prevention campaign called "HIV Stops with ...

Scripps scientists find potential for catastrophic shifts in Pacific ecosystems

...tion. Regimes and rapid shifts between regimes are features that arise from so-called "nonlinear" interactions (where mutual effects do more than add-up, they gang-up and multiply). Nonlinear systems have the capacity for behaviors such as chaos and unpredictable changes of state, changes that can be both dra...

Finding hidden invaders in a Hawaiian rain forest

... sensing has been invaluable for understanding how features or processes that have been observed in one or a few places are distributed in space and time. These new methods discovered a consequence of biological invasion that had not been detected before AND showed how it varies across the landscape." "These...

Doctors closer to using gene analysis to help trauma patients

...uries. Researchers want to understand the genetic features that enhance a patient’s recovery as well as the elements that cause people to die sometimes weeks after an injury occurs. Identifying those factors could help physicians choose the best treatment, a decision that could mean the difference between li...

Marine sponge yields nanoscale secrets

...catalyst. They are learning how to write nanoscale features of semi-conductors on these chip surfaces. A few years ago, Morse and his research group began investigating how nature builds materials from silicon. Silicon is particularly interesting to Morse, because it is considered by many to be the most impo...

Biochemists report discovery of structure of major piece of telomerase; implications for cancer

... "This is a unique RNA structure, with distinctive features of RNA folding," said Feigon, who determined the structure with Theimer and Blois using nuclear magnetic resonance (NMR) spectroscopy. Mutations in the RNA are associated with the inherited diseases aplastic anemia and dyskeratosis congenita, which ...
