Tobacco-related-compound-induced Nitrosative Stress Injury in the Hamster Cheek Pouch

R.D.C. Barley, S. Pollock, M.C. Shallow, E. Peters, and E.W.N. Lam
Tobacco-related compounds, including nicotine, are genotoxic, and 3-nitrotyrosine is a quantifiable marker of peroxynitrite damage in intact hamster cheek pouch tissues.

Progress of Cell Proliferation in Striated Muscle Tissues during Development of the Mouse Tongue

J. Nagata and A. Yamane
The progress of cell proliferation in the muscle tissues of the mouse tongue may be independent of the developmental origins, innervations, and the distance of migration.

Epitope Mapping of Porphyromonas gingivalis Heat-shock Protein and Human Heat-shock Protein in Human Atherosclerosis

J.-I. Choi, S.-W. Chung, H.-S. Kang, B.Y. Rhim, Y.-M. Park, U.-S. Kim, and S.-J. Kim
The authors describe immunodominant cross-reactive epitopes that might be critical in the immunopathogenic process in human atherosclerosis and thus possible candidate peptides for prospective vaccine development against atherosclerosis.

Endurance during Chewing in Whiplash-associated Disorders and TMD

B. Häggman-Henrikson, C. Österlund, and P.-O. Eriksson
Routine examination of patients with whiplash-associated disorders should include jaw function, and the authors describe an endurance test that could also be a useful tool for non-dental professionals.

Information and Participation Preferences of Dental Patients

B.C. Schouten, M.A.J. Eijkman, and J. Hoogstraten
In the study of the etiology of patients’ preferences for information and participation, future research should incorporate factors such as dental anxiety and seriousness of the dental condition.
