In this book, the authors present current research in the study of adhesions. Topics discussed in this compilation include surface analysis techniques for root canal filling adhesion studies; polysialylated-neural cell adhesion molecules in the human nervous system at prenatal, postnatal and adult ages; surgical adhesives; interaction of diamond-transition metal substrates and interfacial adhesion enhancement/failure mechanisms; inhibition and impairment of cell adhesions; and effects of anti-cell adhesion molecules to prevent heart transplant rejection.
