Advancements In Genomics Foster Deep Sea Discoveries

At one time, scientists wondered whether life existed in the deep recesses of the world’s oceans. What kinds of creatures, they wondered, could withstand the dark, cold and extreme pressure of such an environment? Researchers at Scripps Institution of Oceanography at the University of California, San Diego, and their colleagues have used innovations in genomics research to begin to develo...

Computer models aid understanding of antibody-dependent enhancement in spread of dengue fever

Evolutionary trade-off exists between advantage and disadvantage Some viruses' ability to exploit the human body's own defenses to increase their replication may be both a blessing and curse, according to the findings of a study conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. The process is known as antibody-dependent enhancement. Scientists believe antibo...

Findings advance use of adult stem cells for replacement bone

In a significant advance for regenerative medicine, researchers at Rice University have discovered a new way to culture adult stem cells from bone marrow such that the cells themselves produce a growth matrix that is rich in important biochemical growth factors. The research, which appears online this week in the Proceedings of the National Academy of Sciences, is notable not just because...

Bioactive cement scaffold may improve bone grafts

A new technology for implants that may improve construction or repair of bones in the face, skull and jaw, has been developed by researchers from the American Dental Association Foundation (ADAF) and the National Institute of Standards and Technology (NIST). Described in recent and upcoming journal articles,* the new technology provides a method for making scaffolds for bone tissue. The s...

Genes may determine success of hip replacement surgery

The success of long term hip replacement surgery may lie in the genes, suggests research published ahead of print in the Annals of the Rheumatic Diseases. Among those with symptoms, 91 had early signs of “aseptic loosening,?...

Percutaneous aortic valve replacement safe, successful in high-risk patients

Catheter techniques are expanding into new territory, successfully aiding in the replacement of narrowed, calcified aortic valves in patients too sick to withstand open-chest surgery. According to a study reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), May 9?2, 2007, in Orlando, FL, patients who were treated with the CoreValv...
