Abstract
OBJECTIVE A new strategy is required in order to regenerate a meniscus for extensive defects. Synovial mesenchymal stem cells (MSCs) are an attractive cell source for meniscus regeneration due to their high proliferation and chondrogenic potential. We examined the effect of repetitive intraarticular injections of synovial MSCs on meniscus regeneration in a massive meniscal defect of pigs. We followed up the efficacy using MRI evaluation in addition to macroscopic and histological observations. DESIGN Two weeks before the injection of synovial MSCs, the anterior half of the medial menisci was resected in both knees of pigs. Fifty million allogeneic synovial MSCs were injected into the right knee at 0, 2, and 4 weeks and followed up by sequential MRI. The regenerated meniscus, adjacent articular cartilage, and subchondral bone were evaluated by MRI at 2, 4, 8, 12 and 16 weeks. They were also evaluated macroscopically and histologically at 16 weeks (n = 7). RESULTS The resected meniscus regenerated significantly better in the MSC group than in the control group based on histological and MRI analyses. Macroscopically, the meniscal defect already appeared to be filled with synovial tissue at 2 weeks. Articular cartilage and subchondral bone at the medial femoral condyle were also significantly more preserved in the MSC group based on MRI, macroscopic, and histological analyses. CONCLUSIONS Intraarticular injections of allogeneic synovial MSCs appeared to promote meniscus regeneration and provide protection at the medial femoral articular cartilage in a porcine massive meniscal defect model.

Abstract
Soft tissue sarcomas are uncommon in the head and neck. Primary angiosarcomas of the oral cavity area are extremely rare, and have mostly been presented as case reports. This paper presents the clinical and histological features of three such cases. All patients were diagnosed based on the presence of rapidly extending masses involving the tongue, maxillary gingiva, or mandibular gingiva; bone destruction was present in two cases. The resected specimens revealed clustered large, pleomorphic, and spindle-shaped cells with a markedly haemorrhagic background. Tumour cells showed expression of vascular endothelial markers, such a CD31, CD34, and factor VIII-related antigen. Despite undergoing radical surgery, distant metastases developed in all three cases. We also studied the clinicopathological features of a series of oral angiosarcomas. This article therefore reports the clinicopathological features of the three new cases and provides a review of the cases of primary oral angiosarcoma reported during the past 20 years.

Abstract
We investigated completion phenomenon for proverbs in cases demonstrating transcortical sensory aphasia due to a variety of diseases. Lack of this completion was exclusively observed in patients with focal atrophy. These patients showed a selective and consistent impairment in word comprehension without phonemic cue effects in naming. The completion phenomenon was present in patients demonstrating transcortical sensory aphasia due to other cerebral diseases. In these patients, comprehension deficits were not selective for words, or words not comprehended were inconsistent and some phonemic cue effects were observed. In a previous study, we reported that completion phenomena for multiplication tables, serial numbers and names of days were frequently noted in patients with focal atrophy. Together with the present findings, these results suggest that lack of proverb completion may be attributed to a selective, systematic and complete loss of the meaning representations for language units such as words and proverbs. In addition, pathological processes of focal atrophy with temporal predominance might selectively affect the semantic memory for language as a unit.

Abstract
It is important to measure the microdistribution of (10)B in a cell to predict the cell-killing effect of new boron compounds in the field of boron neutron capture therapy. Alpha autoradiography has generally been used to detect the microdistribution of (10)B in a cell. Although it has been performed using a reactor-based neutron source, the realization of an accelerator-based thermal neutron irradiation field is anticipated because of its easy installation at any location and stable operation. Therefore, we propose a method using a cyclotron-based epithermal neutron source in combination with a water phantom to produce a thermal neutron irradiation field for alpha autoradiography. This system can supply a uniform thermal neutron field with an intensity of 1.7×10(9) (cm(-2)s(-1)) and an area of 40mm in diameter. In this paper, we give an overview of our proposed system and describe a demonstration test using a mouse liver sample injected with 500mg/kg of boronophenyl-alanine.

Abstract
The purpose of this study was to clarify the correlation between the radiation dose and histopathological findings in patients with glioblastoma multiforme (GBM) treated with boron neutron capture therapy (BNCT). Histopathological studies were performed on specimens from 8 patients, 3 had undergone salvage surgery and 5 were autopsied. For histopathological cure of GBM at the primary site, the optimal minimal dose to the gross tumor volume (GTV) and the clinical target volume (CTV) were 68Gy(w) and 44Gy(w), respectively.

Abstract
In Japan, multiple organ retrieval from brain-dead heart-beating donors has been gradually increasing since the law was adopted in 1997 and amended in 2009. However, almost more than 90% of total deceased donor kidney transplantation (DDKT) in Japan are still obtained from non-heart-beating donors (NHBD). The majority of NHBD are Maastricht categories IV and III. In category IV, we usually place a double balloon arterial and a venous drainage catheter via the femoral vessels after the diagnosis of clinical brain death and acquisition of informed consent from the family. After controlled cardiac arrest, the double balloons are inflated and in situ cold perfusion started as soon as possible to minimize warm ischemic time (WIT), seeking to achieve a zero to within a few minutes WIT in most cases. In category III, it is impossible to place the device prior to cardiac arrest. In these cases, after declaration of cardiac death, cardiopulmonary compression is accompanied by systemic heparinization, immediate laparotomy, and insertion of a cold perfusion catheter at the aortic and caval bifurcations to minimize WIT. NHBD kidney retrieval is critical; extirpation must be performed as rapidly as possible. The results of NHBD kidney transplantation in Japan are excellent, according to the advancement and utilization of in situ cannulation, organ perfusion, and sophisticated retrieval techniques. The patient and graft survival rates of DDKT at 1, 3, and 5 years in most recent 2001 to 2007 era were 95.4%, 92.2%, 89.1% (n = 945) and 89.2%, 83.7%, 77.8% (n = 919), respectively.

Abstract
STUDY DESIGN Single-subject case. OBJECTIVES To describe the atypical presentation of communication with a blind tetraplegic spinal cord injury patient on a respirator using an electrolarynx. SETTING Critical care center in Osaka, Japan. METHODS A 53-year-old blind man with tetraplegic spinal cord injury was admitted to our center. It was difficult for him to express his desires and to communicate with others about his severe condition and other details of his care. We began to use an electrolarynx to communicate with this patient because he could move his mouth. RESULTS With use of the electrolarynx, the patient gradually became better able to speak fluently by electrolarynx on the first day of use. The electrolarynx allowed us and his family to communicate with him. He was pleased with the improvement in communication. CONCLUSION An electrolarynx is a useful method for communicating with blind tetraplegic spinal cord injury patients on mechanical ventilation.

Abstract
Torsion of an ovary or fallopian tube (adnexal torsion) usually occurs in ovaries with tumors or functional cysts. In polycystic ovarian syndrome (PCOS), the ovaries are bilaterally enlarged, but these enlarged ovaries rarely twist. Recently, the authors encountered a PCOS patient with ovarian torsion after the cessation of Kaufmann treatment. The etiological factors were unclear, but the authors suggest that the increase in ovarian volume was due to transient hypergonadotropic feedback. Thus, more attention should be paid to adnexal torsion that may arise subsequent to transient hypergonadtropic states, in relation to the cessation of hormonal treatment, and enlarged ovaries in PCOS patients.
