Falls are a persistent threat to longevity and quality of life, affecting 1/3 of older adults living in the community each year. There is strong evidence suggesting that a particular pattern within our walking reflects an ability to adapt to a continually changing environment. Specifically, the stride-to-stride patterns of healthy walking have a 1/f frequency spectrum. This has been observed to degrade to varying extents with aging and pathology. The aim of this study was to determine whether the presence of this structure of variability is related to an increased ability to withstand perturbations. We hypothesized that individuals who demonstrated …

Melanins are organic polymers made up of 5,6-dihydroxyindole carboxylic acid (DHICA) and 5,6-dihydroxyindole (DHI). Biochemical systems synthesize melanins through a complex reaction pathway. Previous research exhibited that naturally-occurring melanins (NatMel) and their synthetic analogues (SynMel) can potentially serve as electrode materials for aqueous charge storage devices. Small surface area creates technical challenges for these melanins as charge storage materials. This research herein demonstrates that the structure of melanins can affect the charge storage capacities of monovalent Na+cations and divalent Mg2+ cations. 2-D sheet-like peptide melanins (PepMel) were synthesized into tripeptides consisting of aspartic acid (D), phenylalanine (F), …
