Members of a University of Pennsylvania research team have shown that they can prevent, or even reverse, a blinding retinal disease, X-linked Retinitis Pigmentosa, or XLRP, in dogs. The disease in humans and dogs is caused by defects in the RPGR gene and results in early, severe and progressive vision loss. It is one of the most common inherited forms of retinal degeneration in man. "Every single abnormal feature that defines the disease in the dogs was corrected following treatment,"...

UK scientists create a functional model of the extracellular matrix which could lead to advances in regenerative medicine Scientists at the National Physical Laboratory (NPL) have created a functional model of the native extracellular matrix that provides structural support to cells to aid growth and proliferation. The model could lead to advances in regenerative medicine. The extracellular matrix (ECM) provides the physical and chemical conditions that enable the development of all...

Thanks to a new study of the retina, scientists at UC Santa Barbara have developed a greater understanding of how the nervous system becomes wired during early development. The findings reflect the expansion of developmental neurobiology and vision research at UCSB. The work is described in a recent publication of the Journal of Neuroscience. The research team examined the connectivity of nerve cells, called neurons, in mice. Neurons communicate with one another via synapses where the...

New York University biologists have identified a new mechanism for regulating color vision by studying a mutant fly named after Frank ('Ol Blue Eyes) Sinatra. Their findings, which appear in the journal Nature, focus on how the visual system functions in order to preserve the fidelity of color discrimination throughout the life of an organism. They also offer new insights into how genes controlling color detection are turned on and off. Many biologists study how different cells develop to...

  • Having so marked an appearance as easily to be recognized.
This word may come from the Swedish 'kanspak,' quick at recognizing persons or things, or else from confusion with 'conspicuous.'
