Sonic hedgehog (SHH) and its signaling have been identified in several human cancers, and increased levels of its expression appear to correlate with disease progression and metastasis. However, the role of SHH in bone destruction associated with oral squamous cell carcinomas is still unclear. In this study we analyzed SHH expression and the role played by(More)
The stochastic network calculus receives much attention as a new methodology for end-to-end performance evaluation of networks, taking account of the effect of statistical multiplexing. In our previous paper, we proposed a new stochastic network calculus for many flows from an approach like large deviations techniques, and obtained asymptotic end-to-end(More)
PURPOSE To identify the short-term outcome of patients who had seizures while watching an animated cartoon TV program, "Pocket Monster," on December 16, 1997. METHODS One and three years after the incident, questionnaires were sent to physicians of each patient about seizure recurrence, EEGs, and medication. RESULTS Among 103 patients in whom epileptic(More)
BACKGROUND Tachykinin 3 (TAC3) and its preferred tachykinin receptor 3 (TACR3) that are prominently detected in the central nervous system, play significant roles in physiological development and specifically in the human reproductive system. The roles of TAC3/TACR3 in oral squamous cell carcinoma are unknown. MATERIALS AND METHODS We examined the(More)
In a review of 145 children with partial onset epilepsy, the authors were able to determine a focus of children whose complex partial seizures (CPS) ran a benign course, who had no identifiable lesion on scanning and whose EEG focus was not fixed, but tended to shift. The authors suggest that a benign form of CPS in children can be recognised.
Admission control is a procedure to guarantee a given level of Quality of Service (QoS) by accepting or rejecting arrival connection requests. There are many studies on backlog or loss rate evaluation formulas for admission control at a single node. However, there are few studies on end-to-end evaluation formulas suitable for admission control. In a(More)
Segmental wall motion abnormalities are common in patients with myocarditis. Left ventricular (LV) regional wall motion was assessed in six patients with myocarditis by two-dimensional echocardiography. Some of our patients demonstrated regional thinning of the wall, similar to myocardial infarction. Therefore, segmental wall motion abnormalities with or(More)
The stochastic network calculus receives much attention as a new methodology for end-to-end performance evaluation of networks, taking account of the effect of statistical multiplexing. In this paper, we present a new stochastic network calculus for many flows from an approach like large deviations techniques. In an n-node discrete-time tandem network with(More)
Head and neck squamous cell carcinomas (HNSCCs) frequently invade the bones of the facial skeleton. Semaphorin 4D (Sema4D) is an axon guidance molecule produced by oligodendrocytes. Sema4D was also identified in the bone microenvironment and many cancer tissues including HNSCC. To date, however, the role of Sema4D in cancer-associated bone disease is still(More)
