WAUKEGAN, Ill., March 31, 2014 /PRNewswire/ -- Pfanstiehl just announced the launch of its new high purity, low endotoxin, non-animal-derived Galactose (USP/NF, EP), manufactured in the US under strict cGMP, ICH Q7 compliant conditions. "Process scientists have observed the benefits of Galactose as a cell culture media component for years, but have had difficulty justifying the use of an animal origin or non-cGMP material," says Dr. Christopher Wilcox, VP, Business Development at...

Photoreactive compounds developed by LMU scientists directly modulate nerve-cell function, and open new routes to the treatment of neurological diseases, including chronic pain and certain types of visual impairment. All modes of sensory perception are based on communication between nerve cells. Both the response to the primary stimulus and the transmission of the resulting signal depend on the function of specialized receptor proteins that are associated with the surface membranes of...

Progressive degeneration of photoreceptors—the rods and cones of the eyes—causes blinding diseases such as retinitis pigmentosa and age-related macular degeneration. While there are currently no available treatments to reverse this degeneration, a newly developed compound allows other cells in the eye to act like photoreceptors. As described in a study appearing in the February 19 issue of the Cell Press journal Neuron, the compound may be a potential drug candidate for treating patients...

Animal study reveals “unexpected” role of horizontal cells in photoreceptor rod and cone cell development of retina Scientists are developing a clearer picture of how visual systems develop in mammals. The findings offer important clues to the origin of retinal disorders later in life. In research published this week in the Journal of Neuroscience, University at Buffalo scientists and colleagues focused on a particular protein, called a transcription factor, that regulates gene...

Improving The Skin's Response To UVA Light
2013-01-22 05:41:26

April Flowers for redOrbit.com - Your Universe Online A group of researchers from Brown University have demonstrated that certain skin cells use a light-sensitive receptor found outside of the eye to detect ultraviolet light and quickly begin producing melanin to prevent DNA damage. The same team, in a new study published in Proceedings of the National Academy of Sciences, has identified a key player in that biomolecular chain of events that could become a pharmacological target for...

On the road at night or on a tennis court at dusk, the eye can be deceived. Vision is not as sharp as in the light of day, and detecting a bicyclist on the road or a careening tennis ball can be tough. New research reveals the key chemical process that corrects for potential visual errors in low-light conditions. Understanding this fundamental step could lead to new treatments for visual deficits, or might one day boost normal night vision to new levels. Like the mirror of a telescope...

Researchers Find Easier Way To Perform Macular Degeneration Eye Test

Lawrence LeBlond for redOrbit.com - Your Universe Online Age-related Macular Degeneration (AMD) is a condition that generally occurs in people over the age of 50, but also occurs in higher numbers of people who smoke, who are white, and people who have a family history of the often debilitating condition. And for those who had gone through AMD testing, they had generally had to sit in a darkened room for 20 minutes before testing had begun. But now, researchers from Australia´s...

Research conducted at the Angiogenesis Laboratory at Massachusetts Eye and Ear Infirmary, has for the first time, identified the mode of death of cone photoreceptor cells in an animal model of retinitis pigmentosa (RP). This groundbreaking study, led by Demetrios G. Vavvas, M.D., Ph.D., and including Joan W. Miller, M.D., Mass. Eye and Ear/Mass General Hospital Chief of Ophthalmology and Chair of Ophthalmology at Harvard Medical School, has further identified the receptor interacting protein...

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...

After more than three decades of research, University of Pennsylvania veterinarians and vision-research scientists, with associates at Cornell University, have identified a gene responsible for a blindness-inducing disease that afflicts dogs. In the process, the Penn scientists may have discovered clues about how retinal cells, and perhaps even neurons, can be regenerated. The research was conducted by Gustavo D. Aguirre, William A. Beltran, Agnes I. Berta and Sem Genini of Penn's School...
