Effectiveness of a Telephone‐Delivered Walk With Ease Program on Arthritis‐Related Symptoms, Function, and Activity: A Randomized Trial

Arthritis Care &Research, EarlyView.
Objective Walk With Ease (WWE) is a six‐week arthritis‐appropriate evidence‐based physical activity program traditionally offered in a face‐to‐face format. Because many populations encounter participation barriers to in‐person programs, WWE was modified for telephone delivery (WWE‐T).

Elucidating the Supramolecular Interaction of Positively Supercharged Fluorescent Protein with Anionic Phthalocyanines

Advanced Biology, EarlyView.
Positively supercharged mGreenLatern protein is self‐assembled electrostatically with negatively charged zinc phthalocyanines to yield bio‐based photoactive materials in aqueous media. The addition of phthalocyanines results in the formation of large complexes fully quenching of the protein fluorescence. The results indicate an energy transfer from the
