Artifical cornea lets woman blind 20 years see

...rnea, or keratoprosthesis, into one of her eyes -- restoring her sight in that eye and ultimately helping her regain much of her independence. Phifer is one of several hundred patients nationwide who have received such artificial corneas, which have revolutionized the treatment and care of patients like her. ...

Pair of cancer genes found to drive both cell migration and division

...eba's own PTEN, the human version cleaned up PIP3, restoring its normal distribution within the cell. This indicates that human cells likely use the new mechanism to divide as well. The next steps are to study the roles of the two genes in dividing cells by seeing if controlling the location of the PTEN and P...

Researchers pioneer new gene therapy technique using natural repair process

...the interleukin-2 receptor (IL-2R) in human cells, restoring both gene function and the production of the IL-2R protein. Mutations in the IL-2R gene are associated with a rare immune disease called severe combined immunodeficiency disease, or SCID. Children with SCID are unable to successfully fight off infect...

Stem cell treatment improves mobility after spinal cord injury

...derived treatment they developed was successful in restoring the insulation tissue for neurons in rats treated seven days after the initial injury, which led to a recovery of motor skills. But the same treatment did not work on rats that had been injured for 10 months. The findings point to the potential of us...

Stem cells in bone marrow replenish mouse ovaries

...first step toward investigating such potential for restoring fertility. In addition, the findings open the door for future studies examining whether restoration of ovaries could postpone the hormonal effects of menopause and could represent an alternative to hormone replacement therapy. Finally, the researcher...

Study shows eutrophic lakes may not recover for a millennium

...eveloping larger buffers around lakes and streams, restoring wetlands and encouraging the use of new manure storage and handling processes are also steps that can be taken to reduce phosphorus runoff. "Anything we can do to reduce the erosion of phosphorus is going to be beneficial," Carpenter says. ...

No small feat: First ever gene therapy success for muscular dystrophy achieved

...by binding to the key proteins on either end, thus restoring the cell's outside scaffolding and reestablishing the missing link to key structures inside the cell. Clearly, the authors are most excited about the impressive results achieved in their experiments using systemic gene delivery, which proved there c...

OHSU researchers discover potential mechanism to repair brain damage linked to Multiple Sclerosis

Getting close to nature is good for you

...his week's BMJ. The theory is known as ecotherapy: restoring health through contact with nature. Use of wildlife in some therapies is reported to improve quality of life, write the authors. Smaller animals (for example, squirrels, owls, and raccoons) have been used successfully in therapies for children with ...

Doing that involved a new gene therapy technique, explains Dr. Thébaud. Knowing that a particular protein, VEGF, a vascular endothelial growth factor, is crucial for...

Scientists crack code for motor neuron wiring

...understanding this code may help guide progress in restoring motor neuron function in people whose spinal cords have been damaged by trauma or disease. The studies suggest that the code -- which involves members of the family of transcription factors encoded by the Hox genes -- could also govern the establishm...
