Scientists focus on 'dwarf eye'

...detecting cells. Blindness occurs when these cells die after detachment of the retina from the RPE. Beneath the RPE are two layers of structural tissue that give the eye its shape. During childhood, these tissues stretch, like a balloon, as the eye grows. "The RPE is believed to be the key link in sign...

Fundamental discovery -- Bone fracture

Engineered molecule amplifies body's immune response

...o infection. In the more severe case, the children die in infancy of fatal viral infections. In less severe cases, they later develop infections due to mycobacteria. When interferon levels are too high, for example during treatment with interferon, there are side effects due to the increased nonspecific ...

Virologist finds contagious equine flu in dogs

...on that lasts a few weeks, although 1 to 5 percent die from related hemorrhagic pneumonia. From January to May 2005, outbreaks occurred at 20 racetracks in 10 states (Florida, Texas, Arkansas, Arizona, West Virginia, Kansas, Iowa, Colorado, Rhode Island and Massachusetts), according to the paper. "This ...

Chemical 'band-aid' prevents heart failure in mice with muscular dystrophy

... too. Many people with Duchenne muscular dystrophy die in their 20s from heart failure caused by cardiomyopathy, a gradual weakening of the heart muscle. Heart failure is the second leading cause of death in DMD. The chemical sealant that protected hearts in dystrophic mice from damage is called poloxam...

Study identifies gene in mice that may control risk-taking behavior in humans

...neuroD2 genes were not possible because these mice die within a few weeks of birth. In one experiment, mice were exposed to an adverse stimulus coupled with a non-adverse stimulus, a tone followed by a mild foot shock. Normal mice crouch down and stop moving the next time they hear the tone, a physiol...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

...y the time they are five. Few children in the U.S. die from RSV but it also attacks the elderly, causing some 17,000 to 18,000 deaths annually. Individuals with impaired immune systems are another highly susceptible group. Worldwide, the virus causes about one million deaths annually. Current methods of...

How cell suicide protects plants from infection

...is localized to a small number of cells that later die and form discrete brown lesions on the leaves. When the gene is inactivated, the plant can no longer regulate PCD, leading to cell death throughout the leaf and plant. PCD has been described in virtually all cell types, both plant and animal. It is ...

Leading scientists rank endangered dolphins, porpoises most in need of immediate action

Some species are being pushed to the brink of extinction," said Karen Baragona of WWF's species conservation program.

Research suggests fitness of Florida panthers improved by limited breeding with Texas animals

The paper also notes that "hybrid cats are beginning to expand their ranges to areas previously thought to be unsuita...

Ants, not evil spirits, create devil's gardens in the Amazon rainforest, study finds

...called formic acid into the leaves, which began to die within 24 hours. "Most of the leaves on these saplings were lost within five days, and the proportion lost was significantly higher than on ant-excluded saplings," the authors write. On the other hand, cedars treated with Tanglefoot fared well, wheth...

Gene loss accelerates aging

...th only one copy of the gene. Still, these animals die at a young age. So to study p63 function in adults, Mills and her colleagues devised a sophisticated molecular genetic technique that enabled them to eliminate both copies of the gene from particular tissues--including skin and other multi-layered ep...

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

...No effective treatments exist and children usually die quite young. Despite gene therapy being among the most vigorously studied approaches for muscular dystrophy, it has been beset with uniquely difficult hurdles. The genes to replace those that are defective in CMD are larger than most, so it has not ...
