Emory Eye Center Implants Its First Retinal Chips In Patients With Retinitis Pigmentosa
An expanded clinical trial conducted by Optobionics Corporation involving the implantation of a retina mircrochip has allowed Emory Eye Center and the Atlanta Veterans Affairs Rehabilitation Research & Development Center to implant the device in several patients. The patients all have retinitis pigmentosa with moderate-to-severe vision loss. Three centers in the United States have been chosen...The Shapes Of Life: NIGMS Project Yields More Than 1,000 Protein Structures
The Protein Structure Initiative (PSI), a national program aimed at determining the three-dimensional shapes of a wide range of proteins, has now determined more than 1,000 different structures. These structures will shed light on how proteins function in many life processes and could lead to targets for the development of new medicines. The PSI is a 10-year, approximately $600 million pr...Navigating the brain for sense of direction as paradigm for higher cognitive functions
No matter how healthy a life one leads, no person has managed to live much longer than a century. Even though the advances of the modern age may have extended the average human life span, it is clear there are genetic limits to longevity. One prominent theory of aging lays the blame on the accumulation of damage done to DNA and proteins by “free radicals,?highly reactive molecules produced by the...UC San Diego biologists solve plant growth hormone enigma
Gardeners and farmers have used the plant hormone auxin for decades, but how plants produce and distribute auxin has been a long-standing mystery. Now researchers at the University of California, San Diego have found the solution, which has valuable applications in agriculture. The study, published in the July 1 issue of the journal Genes and Development, describes the discovery of a wh...Protein splicing upsets the DNA colinearity paradigm
Understanding medical research problems often relies on the direct, linear relationship between the sequence of a protein and the DNA encoding that protein. In fact, colinearity of DNA and protein sequences is thought to be a fundamental feature of the universal genetic code. However, a paper published today in Science by a team from the Brussels Branch of the global Ludwig Institute for Cancer R...Glutathione-S-Transferase (GST) Colorimetric Assay Kit from Sigma-Aldrich
Description:Biochem/physiol Actions: Glutathione-S-transferases (GSTs) are a group of enzymes important in the detoxification of many xenobiotics in mammals. The enzymes protect cells against toxicants by conjugating the thiol group of the glutathione to electrophilic xenobiotics, and thereby defend cells against the mutagenic, carcinogenic, and toxic effects of the compounds. GST activity is presen...ATX Ponceau S red staining solution from Sigma-Aldrich

The brightly-colored coral reefs that make scuba-diving and snorkeling so enjoyable when vacationers stay in the Caribbean or South Pacific are essential to the survival of many species of fish and underwater life. Not only do the reefs offer a haven for smaller fish to hide from the larger predators, but also some fish actually surv...Treatment Options For Retinitis Pigmentosa Questioned
Retinitis pigmentosa, a progressive eye disease targeting the light-collecting cells of the retina, affects one in 4,000 people worldwide and can cause // vision loss. Researchers say for patients suffering from retinitis pigmentosa, the addition of docosahexaenoic acid to vitamin A therapy may not provide long-term benefits, according to a recent study. Researchers followed 221 patients...The effects of Curcumin: a natural pigment in turmeric explored for its anti-cancer properties
Curcumin, the natural pigment that gives the spice turmeric its yellow color, has come under the scientific spotlight in recent years, with studies investigating its cancer-fighting abilities // .
