From Globular Proteins to Amyloids proposes a model and mechanism for explaining protein misfolding. Concepts presented are based on a model originally intended to show how proteins attain their native conformations. This model is quantitative in nature and founded upon arguments derived from information theory. It facilitates prediction and simulation of the amyloid fibrillation process, also identifying the progressive changes that occur in native proteins that lead to the emergence of amyloid aggregations.

Discussion and conclusions
Chapter 10. Amyloids identification based on fuzzy oil drop model
Chapter 10.A. Amyloid as a ribbon-like micelle
Amyloid Aβ(1–40) peptide with the Osaka mutation (E22Δ)
