He will present these findings for the first time on Sunday, April 19, 2009 at 10:30 a.m. at the Ernest N. Morial Convention Center, Nouvelle C Room, at the American Society for Nutrition, Experimental Biology 2009 Annual Meeting.
With funding from the National Eye Institute of the National Institutes of Health, Dr. Bazan and his colleagues developed a cell model with a mutation of the Ataxin-1 gene. The defective Ataxin-1 gene induces the misfolding of the protein produced by the gene. These misshapened proteins cannot be properly processed by the cell machinery, resulting in tangled clumps of toxic protein that eventually kill the cell. Spinocerebellar Ataxia, a disabling disorder that affects speech, eye movement, and hand coordination at early ages of life, is one disorder resulting from the Ataxin-1 misfolding defect. The research team led by Dr. Bazan found that the omega three fatty acid, docosahexaenoic acid (DHA), protects cells from this defect.
Dr. Bazan's laboratory discovered earlier that neuroprotectin D1 (NPD1), a naturally-occurring molecule in the human brain that is derived from DHA also promotes brain cell survival. In this system NPD1 is capable of rescue the dying cells with the pathological type of Ataxin-1, keeping their integrity intact.
"These experiments provide proof of principle that neuroprotectin D1 can be applied therapeutically to combat various neurodegenerative diseases," says Dr. Bazan. "Furthermore, this study provides the basis of new therapeutic approaches to manipulate retinal pigment epithelial cells to be used as a source of NPD1 to treat patients with disorders characterized by this mutation like Parkinson's, Retinitis Pigmentosa and some forms of Alzheimer's Disease."

Florida State University researchers examined the relationship between cardiovascular disease (CVD) risk factors such as body mass index, serum lipids and levels of high-sensitivity C-reactive protein (hs-CRP), and the degree to which these factors are influenced by dietary intake of fiber, fat and eggs. The study found:
no relationship between egg consumption and serum lipid profiles, especially serum total cholesterol, as well as no relationship between egg consumption and hs-CRP a positive correlation between dietary trans-fat intake and CVD risk factors, as well as a negative correlation between fiber and vitamin C intake and CVD risk factorsIn additional research presented at Experimental Biology, investigators with Exponent, Inc. evaluated egg consumption data from the NHANES III Follow-Up Survey to determine the association between egg consumption and heart health. The researchers developed a statistical model which showed:
no increased risk of death from coronary heart disease with increased egg consumption a reduced risk of mortality among men who consumed one to six eggs/week compared to less than one egg/week a significant reduction in risk of stroke among women who consumed one to six eggs/week and one or more eggs/dayThese studies support more than 30 years of research showing that healthy adults can consume eggs as part of a healthy diet. Eggs are all-natural and packed with a number of nutrients. One egg has 13 essential vitamins and minerals in varying amounts, high-quality protein and antioxidants, all for 70 calories. Eggs are also an excellent source of choline, an essential nutrient required for life's most basic functions and vital for fetal and infant brain development.
