MU researcher placing eye implants in cats to help humans see

...tial uses for this technology and the potential to create improved vision in some of the millions of people affected worldwide with retinal blindness," Narfstrom said. "This technology also may be beneficial for pets that have similar diseases because this technology can benefit both animals and humans."...

Researchers discover gene crucial for nerve cell insulation

Surgeons develop simpler way to cure atrial fibrillation

... heart within the jaws of the device, surgeons can create lines of ablation, or scar tissue, on the heart muscle. In the older Cox-maze III procedure, the lines of ablation were made by cutting the heart muscle, sewing the incisions back together and letting a scar form. The ablation lines redirect the abno...

New cell type identified in cancer development

... pCSCs, like normal stem cells, had the ability to create various types of benign cells in mice with healthy or recovering immune systems. These daughter cells, however, were likely to die, especially when they encountered signals to further differentiate ?a strong contrast to the behavior of normal stem ce...

Scientists sequence genome of parasite responsible for common sexually transmitted infection

...e medicines to treat the infection and potentially create a way to prevent infection altogether," says NIAID Director Anthony S. Fauci, M.D. Trichomoniasis is a sexually transmitted infection that affects both men and women and results in roughly 7.4 million new cases in the United States each year, acco...

Scientists find potential 'off-switch' for HIV virus

...before it can happen," Weinberger said. "If we can create drugs that target these enzymes, perhaps we can get SirT1 and related enzymes to assert themselves immediately, forcing HIV into hibernation with high frequency and reducing the threat to the host." Weinberger said that drugs already exist that t...

Instruction manual for creating a molecular nose

...duced to the cell extract. Previous attempts to create biosensors from membrane proteins failed due to an idiosyncrasy of these proteins: they are not water soluble. In the past, researchers tried to remove the proteins from their biological membranes by solubilising the latter using detergents. However,...

...respond against antigen. "Our next step is to create a strategy that allows us to downplay the regulato...cumulate the protein, which led the researchers to create a strategy that would allow the immune system to destroy tumor cells by targeting p53. "Instea...

Researchers develop technique for bacteria crowd control

...ient. The researchers used an electric current to create a controlled deviation of the pH levels from the bulk values. Since only living bacteria respond to the pH stimulation, using this method can separate living and dead cells or bacteria with different motility. The device, capable to change the th...

New study may show how to forestall a fatal, virus-caused immune-system meltdown

...une response in the right way at the right time to create safe and effective therapies.? According to Bowick, the Pichinde experiments have already generated some therapeutic leads, thanks to the unexpected discovery that a growth factor receptor molecule normally associated with cancers was activated lat...

Scientists unveil piece of HIV protein that may be key to AIDS vaccine development

...ntact without requiring a shape change in gp120 to create a stable bond between the two molecules. Essentially, the scientists found that the initial point of CD4 contact is a site of gp120 weakness because it is the site of recognition—called an epitope—for b12. "One of our primary goals is to develop H...

Breakthrough in understanding type-2 diabetes as key genes identified

...d a family link. Our new findings mean that we can create a good genetic test to predict people's risk of developing this type of diabetes. "If we can tell someone that their genetics mean they are pre-disposed towards type-2 diabetes, they will be much more motivated to change things such as their diet ...

Junek is also giving him other valuable insights gained through personal observations. Last year, when the grasshoppers re...

Genes and biomarkers that allow doctors to choose the right therapy for the right patient

...will respond to cancer therapies, enabling them to create more effective therapies for individual cancers ?personalized medicine. At the 2007 Annual Meeting of the American Association for Cancer Research, researchers present new biomarkers ?and techniques for determining biomarkers ?that could determine ho...

RNA enzyme structure offers a glimpse into the origins of life

...r its function and which parts could be removed to create a "minimal construct." At UC Santa Cruz, he began trying to grow crystals of the ribozyme so that he could use x-ray crystallography to determine its structure. Crystallizing RNA molecules is extremely difficult, and Robertson tried dozens of diff...

Gene therapy for blindness clears hurdle in mice

...ally muzzled, scientists have begun experiments to create a therapy in which healthy versions of the gene can be introduced into the eye using an apparently harmless virus to deliver the genetic material. "If we reduce the amount of protein formed by mutated rhodopsin, that may be sufficient to maintain ...

Applied scientists create wrinkled 'skin' on polymers

...are affected, the method enabled the scientists to create a variety of patterns--from simple one-dimensional wrinkles to peculiar and complex hierarchical nested wrinkles--along desired paths. Specific examples to date include "S" shapes, circular patterns, and long horizontal channels akin to the repeating...
