July 23, 2009 Circulating osteogenic precursor (COP) cells form bone in vivo. Bone from Blood: Circulating Cells Form Bone Outside the Normal Skeleton, Penn Study Finds
The accepted dogma has been that bone-forming cells, derived from the body's connective tissue, are the only cells able to form the skeleton. view more (2009-07-24)
Magnetic computer sensors may help study biomolecules
Magnetic switches like those in computers also might be used to manipulate individual strands of DNA for high-speed applications such as gene sequencing, experiments at the National Institute of Standards and Technology (NIST) suggest. view more (2007-05-11)
Penn researchers enlist proteins to 'switch on' heart tissue repair system in animal models
Researchers at the University of Pennsylvania School of Medicine are utilizing a protein to "switch on" the ability to repair damaged heart tissue. view more (2006-07-10)
Death rates decline following coronary bypass surgery regardless of hospital volume
Rates of death following coronary artery bypass graft (CABG) surgery have declined since 1997 while the number of procedures performed has decreased, according to a report in the April issue of Archives of Surgery, one of the JAMA/Archives journals. view more (2008-04-22)
HEART FAILURE UNDERDIAGNOSED IN UK PRIMARY CARE (pp 432, 439)
A UK study published in this week’s issue of THE LANCET suggests that heart failure is more common than previously thought. New strategies involving the assessment of left-ventricular function in patients with suspected heart failure could lead to more successful treatment. An estimated 120,000 patients are admitted to hospital every year... view more... (2001-08-08)
UC Davis researchers find decrease in hysterectomy complications
UC Davis researchers who studied hospital discharge records for nearly 650,000 California women over a 13-year period have found that complications from hysterectomies have significantly declined. view more (2008-09-18)
Gene That Controls Ozone Resistance of Plants Could Lead to Drought-Resistant Crops
Biologists at the University of California, San Diego, working with collaborators at the University of Helsinki in Finland and two other European institutions, have elucidated the mechanism of a plant gene that controls the amount of atmospheric ozone entering a plant's leaves. view more (2008-02-28)
Research uncovers new steps on pathway to enlarged heart
Researchers have new insight into the mechanisms that underlie a pathological increase in the size of the heart. The research, published by Cell Press in the October 24th issue of the journal Molecular Cell, may lead to the development of new strategies for managing this extremely common cardiac ailment that often leads to heart failure. view more (2008-10-24)
Smart memory foam made smarter
Researchers from Northwestern University and Boise State University have figured out how to produce a less expensive shape-shifting "memory" foam, which could lead to more widespread applications of the material, such as in surgical positioning tools and valve mechanisms. view more (2009-09-24)
Making a face: A new and earlier marker of neural crest development
The fate of cells that go on to form the face, skull and nerve centers of the head and neck in vertebrates is determined much earlier in development than previously thought, and is independent of interaction with other forming tissues. view more (2006-07-12)
Study compares 2 nonsurgical treatments for reflux disease
Two non-surgical, non-pharmacological treatments for gastroesophageal reflux disease (GERD) both appear effective in reducing medication use and improving voice and swallowing symptoms, according to a report in the January issue of Archives of Surgery, one of the JAMA/Archives journals. view more (2009-01-20)
Berkeley Researchers Identify Photosynthetic Dimmer Switch
In a study of the molecular mechanisms by which plants protect themselves from oxidation damage should they absorb too much sunlight during photosynthesis, a team of researchers has discovered a molecular "dimmer switch" that helps control the flow of solar energy moving through the system of light harvesting proteins. view more (2008-05-09)
