Accidental damage to thin or buried nerves during surgery can have severe consequences, from chronic pain to permanent paralysis. Scientists at the University of California, San Diego School of Medicine may have found a remedy: injectable fluorescent peptides that cause hard-to-see peripheral nerves to glow, alerting surgeons to their location even before the nerves are encountered. The findings are published in the Feb. 6 advance online edition of the journal Nature Biotechnology. Nerve...

Chandra Tucker shines a blue light on yeast and mammalian cells in her Duke University lab and the edges of them start to glow. The effect is the result of a light-activated switch from a plant that has been inserted into the cell. Researchers could use this novel "on-off switch" to control cell growth or death, grow new tissue or deliver doses of medication directly to diseased cells, said Tucker, an assistant research professor in the biology department at Duke. She and colleagues created...

Fluorescent microscopy makes use of molecules, such as green fluorescent protein (GFP), that emit colored light when illuminated with light of a specific wavelength. Molecules like GFP can be used to label proteins of interest and can reveal information about the relationships of molecules within cells. Fluorescence polarization, also known as anisotropy, is specific parameter of fluorescence that can provide additional information about the properties of individual molecules. Fluorescence...

Development Will Open New Avenues for Research Researchers from Carnegie Mellon University's Molecular Biosensor and Imaging Center (MBIC) are turning up the brightness on a group of fluorescent probes called fluoromodules that are used to monitor biological activities of individual proteins in real-time. This latest advance enhances their fluormodule technology by causing it to glow an order of magnitude brighter than typical fluorescent proteins. The new fluoromodules are five- to...

Scientists in Southampton, UK, and Ulm and Karlsruhe in Germany have shown that a variant form of a fluorescent protein (FP) originally isolated from a reef coral has excellent properties as a marker protein for super-resolution microscopy in live cells. Their findings have been published online by Nature Methods and will appear in print in the upcoming August issue of that journal. Fluorescent proteins produced by a range of marine animals glow with a rainbow of colors, adding to the visual...

Veterinary vision scientists at the University of Pennsylvania have safely and successfully used a viral vector in targeting a class of photoreceptors of the retina called rods, a critical first step in developing gene therapies for inherited blindness caused by rod degeneration. In this study, the viral vector, or missile that carries the genetic material designed to correct a DNA mutation, was not intended to treat a disease but to demonstrate through the use of a fluorescent protein that a...

Scientists at Carnegie Mellon University's Department of Chemistry and Molecular Biosensor and Imaging Center (MBIC) are advancing the state-of-the-art in live cell fluorescent imaging by developing a new class of fluorescent probes that span the spectrum "” from violet to the near-infrared. The new technology, called fluoromodules, can be used to monitor biological activities of individual proteins in living cells in real time. At the 239th national meeting of the American Chemical...

Scientists publish first direct measurements of 'superheating' phenomenon The same antifreeze proteins that keep organisms from freezing in cold environments also can prevent ice from melting at warmer temperatures, according to a new Ohio University and Queen's University study published today in the Early Edition of the journal Proceedings of the National Academy of Sciences. Antifreeze proteins are found in insects, fish, bacteria and other organisms that need to survive in cold...

Splitting fluorescent protein helps image clusters in live cells Half a protein is better than none, and in this case, it's way better than a whole one. A Rice University lab has discovered that dividing a particular fluorescent protein and using it as a tag is handy for analyzing the workings of live cells, particularly in the way they employ iron-sulfur clusters. Iron and sulfur in just the right amounts are critical to good health. They're in the food people eat and vitamins they take...

Model is expected to help researchers better understand social bonding and impairments to such behavior Researchers at the Yerkes National Primate Research Center, Emory University, have successfully generated the first transgenic prairie voles, an important step toward unlocking the genetic secrets of pair bonding. The future application of this technology will enable scientists to perform a host of genetic manipulations that will help identify the brain mechanisms of social bonding and...

The Zebrafish (Danio rerio) is a tropical fish belonging to the minnow family (Cyprinidae). It is a popular aquarium fish, where it is frequently sold under the trade name Zebra danio, and is also an important model organism. Characteristics The zebrafish arose in the Ganges region in Eastern India and is also native to Pakistan, Bangladesh, Nepal and Myanmar. It commonly inhabits streams, canals, ditches, ponds and slow-moving to stagnant water bodies, including rice fields. The...
