p63 is a member of the p53 family and regulates crucial events in the formation of epithelial structures, but the role of p63 in tumor is unclear. We found that Snail-induced epithelial-to-mesenchymal transition (EMT) is accompanied by down-regulation of p63 in human squamous cell carcinomas (SCC). #Np63A is the predominantly expressed p63 isoform in SCC(More)
The global distribution of fluorocarbon-12 and fluorocarbon-11 is used to establish a relatively fast interhemispheric exchange rate of 1 to 1.2 years. Atmospheric residence times of 65 to 70 years for fluorocarbon-12 and 40 to 45 years for fluorocarbon-l1 best fit the observational data. These residence times rule out the possibility of any significant(More)
BACKGROUND Oral human papillomavirus (HPV) infection is associated with oral cancer development. However, few epidemiologic investigations have focused on oral HPV prevalence in healthy individuals. The objective of this study was to provide updated information regarding oral HPV prevalence in patients without oral cancer worldwide. METHODS We(More)
Objective Biocompatible materials such as interconnected porous hydroxyapatite ceramics (IP-CHA) loaded with osteogenic cells and bioactive agents are part of an evolving concept for overcoming craniofacial defects by use of artificial bone tissue regeneration. Amongst the bioactive agents, melatonin (MEL) and basic fibroblast growth factor (FGF-2) have(More)
OBJECTIVE The objective of this study was to clarify significant risk factors for postoperative complications in the oral cavity in patients who underwent oral surgery, excluding those with oral cancer. MATERIAL AND METHODS This study reviewed the records of 324 patients who underwent mildly to moderately invasive oral surgery (e.g., impacted tooth(More)
BACKGROUND Various instruments have been developed for collecting bone debris during intraoral autogenous bone graft procedures in implant surgery. The aim of this study was to quantitatively determine the degree of contamination in bone debris collected by different devices. METHODS Twelve patients underwent autogenous bone collection using a bone(More)
OBJECTIVE The objective of this study was to clarify differences regarding HPV16 infection and gene amplification between the oral cavity and oropharynx in healthy individuals. MATERIAL AND METHODS The subjects were 94 healthy asymptomatic individuals (41 males, 53 females; mean age 58.6 years, range 16-97 years) who visited the Department of Oral and(More)
A method is presented for combining remotely measured temperature soundings and wind data to provide a pressure-height reference level in the upper tropo-sphere. I n an initial phase of the study, balanced heights over North America were computed solely from standard wind reports and were found to conform closely to comparable National Meteorological Center(More)
