Study Finds Protein Levels in Spinal Fluid Correlate to Posture and Gait Difficulty in Parkinson’s Disease

BioFindGoldmanParkinsonsstoryimage.jpg

Levels of a protein found in the brain called alpha-synuclein (α-syn) are significantly lower than normal in cerebrospinal fluid collected in Parkinson’s disease patients suffering from postural instability and gait difficulty, a study led by movement disorders experts at Rush University Medical Center has found.

Number of Obese Years Not — Just Obesity — a Distinct Risk Factor for Heart Damage

VanessaNdumeleInfographic.jpg

In an analysis of clinical data collected on more than 9,000 people, Johns Hopkins researchers have shown that the number of years spent overweight or obese appear to “add up” to a distinct risk factor that makes those with a longer history of heaviness more likely to test positive for a chemical marker of so-called “silent” heart damage than those with a shorter history.

Researchers Achieve 'Olympic Ring' Molecule Breakthrough Just in Time for Winter Games

More than 7,000 miles away from the snowcapped peaks of PyeongChang, scientists from FSU’s Department of Chemistry and Biochemistry unlocked a novel strategy for synthesizing a highly versatile molecule called olympicene — a compound of carbon and hydrogen atoms named for its familiar shape. “An olympicene is a molecule consisting of five rings that resemble the shape of the famous Olympic rings,” said Cottrell Family Professor of Chemistry and Biochemistry Igor Alabugin. “This new process for synthesizing these molecules offers a unique tool for the preparation of structurally precise carbon-rich nanostructures.”
