New effort to battle antibiotic resistance rallies researchers throughout Harvard University
Boston. MA--The National Institute of Allergy and Infectious Diseases of the National Institutes of Health (NIH) have awarded $5 million to an interdisciplinary group of Harvard researchers to launch the Harvard-wide Program on Antibiotic Resistance. Headed by Michael S. Gilmore, Ph.D., (Senior Scientist, Schepens Eye Research Institute and Schepens Professor of Ophthalmology [Department of Microbiology and Molecular Genetics], HMS), the group is uniting Harvard institutions in the fight against methicillin-resistant Staphylococcus aureus (MRSA) and other antibiotic resistant infection. The goal of the project is for the research team with a range of expertise to tackle the problem from different directions, and then to translate those findings into better treatments.

Researchers discover mechanism that helps humans see in bright and low light
Oct. 13, 2009 -- Ever wonder how your eyes adjust during a blackout? When we go from light to near total darkness, cells in the retina must quickly adjust. Vision scientists at Washington University School of Medicine in St. Louis have identified an intricate process that allows the human eye to adapt to darkness very quickly. The same process also allows the eye to function in bright light.

Master Proteins Dictate Retinal Differentiation Timetable
The embryonic construction of the vertebrate retina is a highly ordered affair. Following a precise timetable, six different specialized cell types emerge from a mass of identical, proliferating cells. The process of retinal cell differentiation, when so-called progenitor cells stop dividing and choose among the six fates, depends primarily on homeobox genes, major regulators of embryonic patterning. How these genes control the timing of retinal cell differentiation has remained an open questionuntil now.

Yellow plant pigments lutein and zeaxanthin reduce risk of age-related macular degeneration
Women younger than age 75 years who eat diets rich in the yellow plant pigments lutein and zeaxanthin may have a reduced risk of developing the eye disease age-related macular degeneration, according to a report in the August issue of Archives of Ophthalmology, one of the JAMA/Archives journals. Age-related macular degeneration (AMD) occurs when the macula, the area at the back of the retina that produces the sharpest vision, deteriorates over time. The condition is the leading cause of blindness in aging Americans, according to background information in the article. There is no cure for AMD and limited treatment options are available to slow its progression, so research on preventive measures is essential. Previous studies have suggested a potential link between AMD and lutein and zeaxanthin, plant pigments known as carotenoids and found in leafy green vegetables, corn, egg yolks, squash, broccoli and peas. These compounds may reduce the risk of AMD by absorbing blue light that could damage the macula, by preventing free radicals from damaging eye cells and by strengthening eye cell membranes.

Both ways of experiencing the world are automatic, and the neurons that make up the brain's visual system switch between these two modes continuously. But the exact neurons and mechanisms responsible are still a mystery to neuroscientists.

High Body Mass Index Increase the Genetic Risk of AMD
Current cigarette smoking was associated with a fivefold increased risk and high BMI (30 or higher) was associated with a twofold higher risk of AMD. The homozygous risk genotype (CC) plus smoking conferred a tenfold higher risk of AMD, compared with non-smokers with the non-risk (TT) genotype, while the risk genotype plus higher BMI increased risk of AMD almost sixfold. Gene plus environment risk scores provided an area under the receiver operating characteristic (ROC) curve of 0.70-0.75. The attributable risks for the combination of genes and environment were 69% to 73%.

Statins reduce incidence of nuclear cataract
The use of statins is linked with a lower incidence of nuclear cataract, the most common type of age-related cataract, according to a study in the June 21 issue of JAMA. Statins are widely used to decrease serum cholesterol for cardiovascular disease prevention. Statins have also been shown to have antioxidant activity. Oxidative stress (a condition in which antioxidant levels are lower than normal) has been thought to be a risk factor for age-related cataract, particularly nuclear cataract (the most common type of age-related cataract, which occurs in the center of the lens). Some evidence has suggested an association between nutritional intake of antioxidants and age-related cataract, according to background information in the article.
