Enzyme delivered in smaller package protects cells from radiation damage

... enzyme systemically throughout the body which may spare healthy tissue the long-term consequences of therapeutic irradiation. These results are being presented at the 10th annual meeting of the American Society of Gene Therapy, being held May 30 to June 3 at the Washington State Convention & Trade Cen...

Natural polyester makes new sutures stronger, safer

...es after being implanted in a patient, which would spare children with heart valve defects from undergoing repeated surgeries. Tests of the device in animals have shown promise. "We've been able to show we can produce a valve scaffold that functions better and can grow with the animal," Williams said. "...

Many couples choose to donate surplus embryos for stem cell research

...0% of the couples would be willing to donate their spare embryos for stem cell research," said Pablo Menendez, director of the Spanish Stem Cell Bank in Granada, Spain. The new findings "contrast sharply" with a 2003 report, which found that, of 400,000 embryos stored at that time in U.S. fertility clin...

End of deforestation in view? Experts advance new way to size up global forest resources

...ountries forests have begun to enlarge, as farmers spare land and foresters also shift from extensive to intensive strategies. Says Mr. Ausubel: "This great reversal in land use could stop the styling of a Skinhead Earth and begin a great restoration of the landscape by 2050, expanding the global fores...

Parental genes do what's best for baby

...enomic imprinting ?only use one parent’s copy; the spare copy from the other parent is silenced by a chemical stamp.? The concept of imprinting has long puzzled scientists as it appears to undermine the natural benefits organisms gain from inheriting two sets of genes. If one copy of a gene is damaged...

Coming soon: 3-D imaging that flies 'through' and 'around' cancer

...on "may be used to detect and characterize cancer, spare someone from more invasive medical procedures, lead to better disease detection rates of colon cancer, provide surgical guidance and detect which tumors may be easier to biopsy," detailed Andrew Quon, clinical assistant professor of radiology/diagnos...

New genetic test for breast cancer

...er. "With better individualized treatment, we can spare women the side effects of chemotherapy where it is unnecessary." Dr. Sparano is the lead investigator for the clinical trial, called TAILORx (an acronym for Trial Assigning Individualized Options for Treatment). The study, sponsored by the National...

Johns Hopkins lab scientists tame overactive CF protein

...CF patients. Suspecting that inhibiting VCP would spare the chloride-transporting channels from premature demise, the team showed that when the VCP's level was lowered, it no longer destroyed CFTR. In a second set of tests, researchers blocked the destruction of CFTR with a proteasome-inhibiting drug cur...

Convergent evolution of molecules in electric fish

...tate and evolve without harming the fish. "The spare gene gave [the electric fish] a little bit of evolutionary leeway," says Zakon, professor of neurobiology. "This is really one of the first cases that the ancestral gene duplication in fish has actually been linked to a gene that has been freed up an...

The Amazon in 2050: Implementing the law could save a million square kilometers of rainforest

...g existing laws and proposed protected areas would spare the Amazon one million square kilometers of deforestation (one fifth of the entire forest area), avoiding 17 billion tons of carbon emissions to the atmosphere, the elimination of several forest formations, and the degradation of several major waters...

Young scientists turn to gel to ease side-effects of cancer treatment

...tment of Chemistry have developed a gel that could spare cancer patients some of the unpleasant and dangerous side-effects of radiotherapy. PhD students Andrew Wilson and Paul Watson, together with post-doctoral research fellow Mark Godber, have developed the gel which will help doctors to target cancer t...

Genetic defenders protect crops from fungal disease

...rificing these fallen cells, the defense genes can spare healthy ones from infection. Somerville, Stein, and colleagues at the Max Planck Institute for Plant Breeding in Köln disabled the protective genes in Arabidopsis by introducing mutations, one at a time and in various combinations. They infected the...
