Embryonic Stem Cells Improve Vision of Blind Patients

February 7, 2012 | by

Researchers at UCLA’s Jules Stein Eye Institute and colleagues have successfully used specialized retinal cells derived from human embryonic stem cells to improve the vision of two legally blind patients.

The trial was led by Dr. Steven Schwartz, opthalmologist and chief of the retina division at the Institute. Although the results are extremely promising, only two patients were treated. The trial will have to be preformed successfully many more times before the procedure can be accepted as an option for care.

Nevertheless, the preliminary findings represent a milestone in the therapeutic use of stem cells and may pave the way for a new therapy to treat eye diseases. The research was recently published online in the journal The Lancet.

Just Because It Isn’t Sweet … Doesn’t Mean It Isn’t Sugar

From a nutritional perspective, is a spoonful of white rice more like a spoonful of sugar or a spoonful of brown rice?

The reason has to do with the chemical nature of carbohydrates.

February is American Heart Month. Sponsored by the American Heart Association, American Heart Month is a time to battle cardiovascular disease and educate people on what they can do to live heart-healthy lives. Heart disease, including stroke, is the leading cause of death for men and women in the United States.

How much do you know about the condition of your heart? Heart health awareness typically focuses on heart disease in older adults caused by an unhealthy diet and a lack of exercise. But what if you could be at risk for cardiac arrest and sudden death even though you are young and in shape?

F1000 Launches Open Access Publishing for Biology and Medicine

February 1, 2012 | by

This week, the Faculty of 1000 (F1000), announced F1000 Research, a new fully Open Access publishing program across biology and medicine that will launch later this year [1]. F1000 Research is intended to address the major issues afflicting scientific publishing today: timely dissemination of research, peer review, and sharing of data.
