(CHICAGO) - Gastroenterologists at Rush University Medical Center are studying the safety and efficacy of a new system for delivering chemotherapy for patients with esophageal cancer, a rare, but deadly disease that attacks the throat. The unique drug therapy delivers a highly concentrated dose of chemotherapy injected directly on to the hard-to-reach tumors in the esophagus non-surgically.
In the first demonstration of its kind, researchers at the University of British Columbia have controlled the spin of electrons using a ballistic technique--bouncing electrons through a microscopic channel of precisely constructed, two-dimensional layer of semiconductor.
Westchester, Ill. - A study in the April 15 issue of the Journal of Clinical Sleep Medicine is the first to assess the effectiveness of treating sleep disorders in adults with a traumatic brain injury (TBI). Results indicate that treatment may result in the objective resolution of the sleep disorder without improvements in daytime sleepiness or neuropsychological function.
Rarely will physicians use the word "miraculous" when discussing patient recoveries. But that's the very phrase orthopaedic physicians and scientists are using in upstate New York to describe their emerging stem cell research that could have a profound impact on the treatment of bone injuries.
In parallel studies in human and mouse, two groups of researchers have come to the same conclusion: that a new kind of gene is associated with progressive hearing loss. The new gene - called a microRNA - is a tiny fragment of RNA that affects the production of hundreds of other molecules within sensory hair cells of the inner ear.
In an Early Edition issue of The Proceedings of the National Academy of Sciences (PNAS) on April 9, 2009, the researchers report that they have been able to determine the molecular structure of a plant photolyase protein that is surprisingly similar to two cryptochrome proteins that control the "master clock" in humans and other mammals.
BLOOMINGTON, Ind. - A team led by an Indiana University astronomer has found a sample of massive galaxies with properties that suggest that they may have formed relatively recently. This would run counter to the widely-held belief that massive, luminous galaxies (like our own Milky Way Galaxy) began their formation and evolution shortly after the Big Bang, some 13 billion years ago.
A new therapy for metastatic prostate cancer has shown considerable promise in early clinical trials involving patients whose disease has become resistant to current drugs.
Howard Hughes Medical Institute researchers have designed tiny RNA molecules that shut off the gene that causes Huntington's disease without damaging that gene's healthy counterpart, which maintains the health and vitality of neurons.
PITTSBURGH, April 9 - Stem cells collected from human corneas restore transparency and don't trigger a rejection response when injected into eyes that are scarred and hazy, according to experiments conducted in mice by researchers at the University of Pittsburgh School of Medicine. Their study will be published in the journal Stem Cells and appears online today.
LA JOLLA, Calif., April 8, 2009 -- Investigators at Burnham Institute for Medical Research (Burnham) have deciphered a large percentage of the total protein complement (proteome) in Schizosaccharomyces pombe (S. pombe) fission yeast.
Scientists at Schepens Eye Research Institute have found that the growth factor known as TGF-? is essential to the health of blood vessels in the retina and that blocking it can cause retinal dysfunction.
A new therapy for metastatic prostate cancer has shown considerable promise in early clinical trials involving patients whose disease has become resistant to current drugs.
BIRMINGHAM, Ala. - Motivation and expectation may be factors in helping older adults regain lost functional ability after hospitalization, say researchers with the Birmingham Veterans Administration Medical Center and UAB (University of Alabama at Birmingham).
WINSTON-SALEM, N.C. - Carrying extra weight earlier in life increases the risk of developing problems with mobility in old age, even if the weight is eventually lost, according to new research out of the Sticht Center on Aging at Wake Forest University School of Medicine.
