PURPOSE The purpose of this study was to record transmitted-light photoplethysmography (TLP) from young permanent teeth and examine its applicability to pulp vitality assessment. METHODS Twenty-six healthy and 7 nonvital upper maxillary incisors in 17 children (ages 7 years, 3 months to 14 years, 8 months) were examined. Recordings of TLP were made with(More)
BACKGROUND Maspin is a 42 kDa protein known to act as a tumor suppressor. Although its function has not been fully elucidated, numerous reports have investigated the prognostic impact of maspin in patients with several types of cancer. However, there have been no reports on the association between maspin expression and the prognosis of patients with soft(More)
BACKGROUND In recent years, neoadjuvant chemotherapy (NAC) is often performed for patients with unresectable breast carcinoma or without indication of breast conserving therapy. However, it is currently difficult to predict response to NAC with diagnostic imaging of breast carcinoma. In this study, we investigated imaging findings that could serve as a(More)
We report a 58-year-old man who suffered from shortness of breath on exertion with wheezing. A chest enhanced computed tomography (CT) scan showed an irregular tumor in the middle mediastinum involving the right main pulmonary artery, vena cava superior and right main bronchus. Transbronchial lung biopsy and endobronchial ultrasound-guided transbronchial(More)
We report 3 cases of patients with bronchogenic cyst arising in the posterior mediastinum. The patients were a 19-year-old male, a 36-year-old female and a 33-year-old female, whose cysts were detected as abnormal shadows in the chest. In 2 of them, neurogenic tumors were suspected preoperatively. We performed thoracoscopic resection for the 3 tumors.(More)
differentiation is a fundamental process during endochondral ossification. Retinoic acid (RA) has been shown to regulate this process, however, the mechanisms underlying RA regulation of chondrogenesis are not clearly understood. Chondroprogenitor cells, ATDC5 have been shown to be a useful in vitro model for examining the multiple step differentiation of(More)
