OBJECTIVES Oral health-related quality of life (OHRQoL) is being increasingly used in epidemiologic studies of dentistry. However, patient-reported OHRQoL does not always coincide with clinical measures. Previous studies have shown a relationship between OHRQoL and personality, but did not concomitantly investigate oral function. We aimed to examine the(More)
The MicroHyala(®) microneedle (MN) patch was developed to provide a simple, safe, and effective drug delivery system. In this study, we examined the performance and characteristics of our fabricated MN patch to identify potential quality issues with future commercial application. Mechanical failure force analysis identified that the strength of the MN patch(More)
Poorly differentiated type synovial sarcoma (PDSS) is a variant of synovial sarcoma characterized by predominantly round or short-spindled cell morphology. Although accumulating evidence from clinicopathologic studies suggests a strong association between this variant of synovial sarcoma and poor prognosis, little has been reported on the molecular basis of(More)
Dedifferentiated chondrosarcoma (DDCS) is a rare and aggressive bone tumor with poor prognosis. Primary DDCS of the mobile spine is extremely rare, particularly in the cervical spine. We herein describe a first case of cervical DDCS in an 81-year-old male presenting with a slowly growing mass. Radiographs showed an expansion of the cortical contour of the(More)
PURPOSE OF THE STUDY We examined the relationships among development of generativity, generative acts, and psychological well-being in old age and the possible mediating effects of perceived rejection and respect from younger generations. We hypothesized that generative action would not lead to well-being unless responding elders perceived respect from(More)
This study examined the associations between the complexity of an individual's primary lifetime occupation and his or her late-life memory and reasoning performance, using data from 824 community-dwelling participants aged 69-72 years. The complexity of work with data, people, and things was evaluated based on the Japanese job complexity score. The(More)
OBJECTIVE The present study examined the cultural differences and similarities in the levels and predictors of subjective well-being in Japanese and American centenarians. METHOD We analyzed data on cognitively intact Japanese (N = 59) and American (N = 125) participants from the Tokyo and Georgia Centenarian Studies, respectively. The Philadelphia(More)
OBJECTIVE It is well-documented that midlife hypertension (HT) is associated with decline of cognitive function. Recently, we reported that the influence of HT and/or elevated blood pressure on the progression of cognitive decline was attenuated at late life aged 70 of the general population in cross-sectional analysis. The purpose of this study is to(More)
BACKGROUND Metatarsalgia is frequently associated with hallux valgus. The aim of this study was to evaluate how the relative length and position of the first metatarsal head influenced metatarsalgia and plantar callosities beneath the lesser metatarsal heads. METHODS A retrospective analysis of the clinical data and radiographs of 102 cases was performed(More)
Much of our focus of attention has been on sub-clinical or subtle joint pain experienced by healthy soccer players. The present study aimed to determine at which joint such subclinical pains are the most prominent, and to examine the pain-relieving effect of a chicken comb extract (CCE)-containing supplement product (test product) on these athletes. A total(More)
