Changes of molecular dynamics in the α-to-β transition associated with amyloid fibril formation were explored on apo-myoglobin (ApoMb) as a model system. Circular dichroism, neutron and X-ray scattering experiments were performed as a function of temperature on the protein, at different solvent conditions. A significant change in molecular dynamics was observed at the α-to-β transition at about 55 ˚C, indicating a more resilient high temperature β structure phase. A similar effect at approximately the same temperature was observed in holo-myoglobin, associated with partial unfolding and protein aggregation. A study in a wide temperature range between 20 K and 360 K …

Using MRS imaging and singular value decomposition (SVD), Manganas et al. (Science 318, 980,2007) reported a nuclear magnetic resonance diagnostic for neural progenitor cells. Characteristics of MRS experiments are known to be problematic for SVD-based methods. Absent detection using alternate methods of spectrum analysis or controls to quantify the false discovery rate, little significance can be attached to their result.
