PHILADELPHIA — Nancy Bonini, Gideon Dreyfuss and Beatrice H. Hahn of the University of Pennsylvania have been elected members of the National Academy of Sciences, considered one of the highest honors that can be accorded a U.S. scientist or engineer.
PHILADELPHIA — Having a virtual copy of a patient’s blood in a computer would be a boon to researchers and doctors. They could examine a simulated heart attack caused by blood clotting in a diseased coronary artery and see if a drug like aspirin would be effective in reducing the size of such a clot.
Penn Study Confirms 2 Treatments for Age-related Macular Degeneration Provide Equal Vision Improvements
Two drugs commonly used to treat age-related macular degeneration (AMD) yield similar improvements in vision for patients receiving treatments on a monthly or as-needed basis, according to a study from researchers at the Center for Preventive Ophthalmology and Biostatistics (CPOB) at the Perelman School of Medicine at the University of Pennsylvania.
PHILADELPHIA — If Pygmies are known for one trait, it is their short stature: Pygmy men stand just 4’11” on average. But the reason why these groups are so short and neighboring groups are not remains unclear. Scientists have proposed various theories based on natural selection, including that Pygmies’ reduced size lowered nutritional requirements, helped them better handle hot climates, or allowed them to reach sexual maturity at an earlier age.
A cellular protein called HDAC6, newly characterized as a gatekeeper of steroid biology in the brain, may provide a novel target for treating and preventing stress-linked disorders, such as depression and post-traumatic stress disorder (PTSD), according to research from the Perelman School of Medicine at the University of Pennsylvania.
PHILADELPHIA -- Protein design is technique that is increasingly valuable to a variety of fields, from biochemistry to therapeutics to materials engineering. University of Pennsylvania chemists have taken this kind of design a step further; using computational methods, they have created the first custom-designed protein crystal.
