CRITICAL REVIEWS IN ORAL BIOLOGY & MEDICINE:

Potassium Channel-blockers as Therapeutic Agents to Interfere with Bone Resorption of Periodontal Disease

P. Valverde, T. Kawai, and M.A. Taubman
This review elucidates recent advances in the use of potassium channel-blockers of Kv1.3 and IKCa1 to ameliorate the clinical signs or side-effects of several immunological disorders and to decrease inflammatory bone resorption in periodontal disease.

Parotid Secretory Granules: Crossroads of Secretory Pathways and Protein Storage

S.-U. Gorr, S.G. Venkatesh, and D.S. Darling
The authors suggest that unique sorting and retention mechanisms are responsible for the distribution of secretory proteins to different secretory pathways from the maturing secretory granules in parotid acinar cells.

Dental Epithelial Histomorphogenesis in vitro

B. Hu, A. Nadiri, S. Bopp-Küchler, F. Perrin-Schmitt, and H. Lesot
Initial potentialities of the mesenchyme are not specified by the primary enamel knot, and positional information of dental epithelial cells does not require the memorization of their history.

Gene Expression during Palate Fusion in vivo and in vitro

P. Pungchanchaikul, M. Gelbier, P. Ferretti, and A. Bloch-Zupan
In the organotypic model of palate fusion, the down-regulation of the transcription factor snail that occurs with the progression of palate development is not dependent on fusion of the palatal shelves.

Cyclosporin A Affects Signaling Events Differentially in Human Gingival Fibroblasts

A. Bostrom, H. Bharath, A. Saulewicz, and A.S. Narayanan
Cyclosporin A affects signaling molecules in human gingival fibroblasts differently from other cell types, and the CSA-induced increase in AP-1 activity may affect the expression of fibrogenic molecules in gingiva and promote gingival overgrowth.

Low HEMA Conjugation Induces High Autoantibody Titer in Mice

E. Sandberg, G. Bergenholtz, H. Kahu, and U.I. Dahlgren
The lower the degree of HEMA conjugation to self-protein, the higher the risk for autoantibody production to the carrier protein.

Functional Activity of Superior Head of Human Lateral Pterygoid Muscle during Isometric Force

S. Ruangsri, T. Whittle, K. Wanigaratne, and G.M. Murray
The superior and inferior heads of the human lateral pterygoid muscle should be regarded as a single muscle, with activities shaded according to the biomechanical demands of the task, as previously proposed by Hannam and McMillan (1994).
