The localization of N-cadherin in the normal, and regenerating nerve fibers was investigated by immunocytochemistry in the chicken sciatic nerve. The normal unmyelinated fibers exhibited N-cadherin immunoreactivity on the plasma membranes of axons and Schwann cells where they were in contact with each other, while myelinated fibers displayed no(More)
The ultrastructural localization of R-cadherin in normal and regenerating chick sciatic nerves was investigated immunocytochemically, and was compared with that of N-cadherin. R-cadherin was found on the plasmalemmae of axons and Schwann cells where cell-cell contacts were made in the normal unmyelinated fibers. It was also noted that R-cadherin was(More)
The Ca(2+)-dependent intercellular adhesion molecule cadherin is known to be linked to the cytoskeleton by the protein catenin, an association of which appears to be important for the cell-adhesion function of cadherin. Catenin consists of three subtypes-alpha, beta, and gamma. In our previous study, N-cadherin was shown to be localized on the plasmalemma(More)
The localization of alpha E- and alpha N-catenin in dorsal root ganglia and spinal cord was examined immunocytochemically. Alpha E- and alpha N-catenin appeared to be co-localized in cell bodies of neurons in dorsal root ganglia, but alpha N-catenin was not expressed in cell bodies of neurons in the ventral horn that showed alpha E-catenin expression. These(More)
BACKGROUND Odontogenic diseases can be a risk factor for life-threatening infection in patients with hematologic malignancies during chemotherapy that induces myelosuppression of variable severity. Previous studies noted the necessity of the elimination of all odontogenic foci before hematopoietic stem cell transplantation. To enable planning for the(More)
In this study, cases of temporomandibular joint disorder (TMJD) were analyzed based on the subtype classification established by Japanese Society for the Temporomandibular Joint (JSTMJ) in 2001. The subject of our investigation consisted of cases who visited to the department of Oral and Maxillofacial Surgery of Kobe University Hospital in 2002 because of(More)
Squamous cell carcinoma (SCC) is the main histological type of oral cancer. Its growth rate and incidence of metastasis to regional lymph nodes is influenced by various factors, including hypoxic conditions. We have previously reported that transcutaneous CO2 induces mitochondrial apoptosis and decreases lung metastasis by reoxygenating sarcoma cells.(More)
In sinus floor augmentation of an atrophic posterior maxilla, platelet-rich fibrin (PRF) has been used as a graft material. We herein report two cases with histological evaluations of PRF after the surgery. The first case was a 28-year-old female with an atrophic right posterior maxilla who was treated with sinus floor augmentation and simultaneous implant(More)
There have been few reports of mouth closing disturbances in the final phase of occlusion caused by the posterior thickness of the retrodiscal tissue. Two such cases are described here. The first was a 70-year-old female suffering from a painless mouth closing disturbance on the right side of the temporomandibular joint (TMJ). She complained of a feeling(More)
INTRODUCTION Tumefactive fibroinflammatory lesion is an idiopathic fibrosclerosing disorder occurring in the head and neck region. It is one of a broad spectrum of entities named inflammatory pseudotumors and, as the name suggests, it mimics a lot of diseases such as malignancies or infections. Combined with its rarity, tumefactive fibroinflammatory lesion(More)
