Panoramic dental radiographs are commonly used in general dentistry and oral and maxillofacial surgery to examine upper and lower teeth, maxilla, mandible and the surroundings simultaneously. Carotid artery calcification, a specific indicator of atherosclerotic change of the carotid arteries, can be seen on the radiographs. Many studies have suggested that(More)
In this study, we examined histologically the effect of a bone morphogenetic protein (BMP) derived from bovine tooth on the periosteum. Supraperiosteal injection of crude BMP into femurs of Wistar rats (28 day old) resulted in periosteal cell proliferation with subsequent bone and cartilage formation. Moreover, proliferating periosteal cells migrated into(More)
A dodecapeptide (γ400-411) derived from a fibrinogen γ-chain carboxyl-terminal sequence recognizes specifically the active form of GPIIb/IIIa on the surface of activated platelets. For the purpose of efficient hemostasis, we previously developed ADP-encapsulated liposomes modified with human-dodecapeptide (HHLGGAKQAGDV, human-H12). On the other hand, the(More)
Pure trigeminal motor neuropathy is a very unusual disease that is characterized by trigeminal motor paralysis without trigeminal sensory disturbances and without the involvement of the other cranial nerves. We report a case of pure trigeminal motor neuropathy in a 70-year-old woman. The diagnosis was based on the results of clinical, electromyographic, and(More)
OBJECTIVE Eruption of cleft-associated permanent canines was studied in 190 patients with unilateral cleft lip/palate and whose permanent canines had not erupted at the time of alveolar bone grafting. In 162 of these patients, width of bone defect was compared between patients who underwent surgical exposure of canines and those whose canines erupted(More)
For the purpose of efficient hemostasis, we previously developed ADP-encapsulated liposomes modified with a dodecapeptide (HHLGGAKQAGDV, H12), H12-(ADP)Lipo. This liposome actually enhanced platelet aggregation in vitro, and showed significant hemostatic effect in vivo. Since fibrinogen (Fbg) is abundant in the bloodstream, it is unclear why this liposome(More)
