Abstmct-The use of adaptive routing in a multicomputer inter-connection network improves network performance by making use of all available paths and provides fault tolerance by allowing messages to be routed around failed channels and nodes. This paper describes two deadlock-free adaptive routing algorithms. Both algorithms allocate virtual channels using(More)
BACKGROUND The proportion of suicide attempts by infliction of abdominal stab wounds (ASWs) is higher in Japan than in other counties. There are few clinical reports on these wounds, especially hara-kiri wounds, which involve transversely cutting the abdomen. This study aimed to investigate Japanese patients with self-inflicted hara-kiri wounds and(More)
BACKGROUND Recently it has become well accepted that neurogenesis occurs in the dentate gyrus of the hippocampus, a region important to memory and learning function in rodents and humans. Reports show that neurogenesis in the hippocampus is regulated by certain factors, such as exposure to an enriched environment, physical activity, aging and stress. The(More)
The dentate gyrus (DG) of the hippocampal complex is one of the few areas of the rodent brain where neurogenesis continues throughout adulthood. We investigated the effects of the molarless condition on cell proliferation, rate of differentiation into neurons in the subgranular zone of the DG, and plasma corticosterone levels. The molarless condition(More)
The etiology of a novel cardiac syndrome called "tako-tsubo" cardiomyopathy, otherwise known as "acute onset and reversible left ventricular apical wall motion abnormality (ballooning)," is very similar to that of acute myocardial infarction; however, it may also be associated with emotional or physical stress. We report a case of tako-tsubo-like left(More)
OBJECTIVE Since 2001, at our institution, a portable and percutaneous cardiopulmonary bypass system has been used for rewarming of patients with accidental deep hypothermia. Before 2001, a conventional internal rewarming technique was used. The aim of this research is to examine the efficacy of portable and percutaneous cardiopulmonary bypass for rewarming(More)
BACKGROUND Retropharyngeal hematomas are often associated with blunt cervical spine injury. Generally, they improve with conservative treatment; however, rarely, airway obstruction occurs due to delayed swelling of retropharyngeal hematoma. OBJECTIVES To report a case of sudden asphyxia due to retropharyngeal hematoma caused by blunt thyrocervical artery(More)
The 5-year relapse-free survival rate (5Y-RFS) and 5-year overall survival rate (5Y-OS) were investigated in 766 patients with stage II/III colorectal cancer (CRC). The Stage II group included 283 patients with colon cancer (CC), 40 patients with rectosigmoid junction cancer (RSC), and 74 patients with rectal cancer (RC), while the Stage III group comprised(More)
BACKGROUND There are few reports on long-term convalescence with regard to cardiac injury caused by blunt chest trauma. Nuclear medicine study of the heart (NMSH) in the early stages of injury is reportedly superior to detect the correlation between injury and fatal arrhythmia. Therefore, we prospectively performed NMSH and Holter electrocardiogram (ECG) in(More)
A previously healthy 21-year-old woman, transported to our medical emergency center for excluding organic brain disease, had undergone medical examination 9 days before for trembling in her left hand, which was caused by stress. The patient exhibited fever and strange behaviors, e.g., wandering around, babbling, and making smoking gestures; hence,(More)
