Abstract
Endometriosis is a precancerous condition for endometriosis-associated ovarian cancer (EAOC). In the present study, conventional magnetic resonance imaging (MRI) and MR relaxometry were used to examine a case of clear cell carcinoma that arose in a pre-existing right-sided benign ovarian endometrioma (OE). The 42-year-old nulliparous woman suspected of EOAC, as assessed by conventional MRI, requested fertility-sparing surgery such as laparoscopic endometrioma cystectomy. Furthermore, the MR transverse relaxation rate (R2) was determined using a single-voxel, multi-echo MR sequence using a 3 Tesla-MR system. An R2 value <12.1 s-1 was indicative of malignancy, as described in previous studies. In the present study, MR relaxometry identified an R2 value of 7.98 s-1 in the right cyst, which suggested the malignant transformation of benign OE. Based on these findings, fertility-sparing surgery was contraindicated. In conclusion, MR relaxometry may represent a new clinical approach as an adjunctive modality for the diagnosis of EAOC. When patients exhibiting a pelvic mass suspected of EAOC desire fertility-sparing treatment options, MR relaxometry can facilitate the selection of conservative management.

Abstract
INTRODUCTION Magnetic resonance (MR) relaxometry provides a noninvasive predictive tool to discriminate between benign ovarian endometrioma (OE) and endometriosis-associated ovarian cancer (EAOC). Transverse relaxation rate R2 value was determined using a single-voxel, multi-echo MR sequence (HISTO) by a 3T-MR system. R2 with cutoff value of 12.1 s was established to discriminate between benign and malignant tumors. PATIENT CONCERNS We present a case of a 39-year-old woman who was initially thought to be malignant transformation of endometriosis by diagnostic MR imaging of the vascularized solid components. DIAGNOSIS A R2 value of 42.62 s on MR relaxometry demonstrated that this case is non-malignant. INTERVENTIONS To confirm the diagnose, left salpingo-oophorectomy by laparoscopic surgery was performed. OUTCOMES Histopathological results revealed seromucinous borderline tumor (SMBT). Our experience suggests that preoperative MR relaxometry may be useful for discriminating "borderline (SMBT)" from "malignancy (EAOC)." Furthermore, immunohistochemical studies of this case demonstrated ovarian SMBT cells were positive for estrogen receptor, progesterone receptor, and hepatocyte nuclear factor-1beta. A similar expression pattern was also observed in patients with benign OE. LESSONS In many respects, SMBT characteristics differ from those of EAOC but resemble those of benign OE. MR relaxometry unveils a new clinical approach as an adjunctive modality for discriminating SMBT from EAOC.

Abstract
BACKGROUND Bone marrow-derived mesenchymal stem cells (MSCs) can differentiate into various types of cell, and the extracellular matrix (ECM) is acknowledged to be important for the regulation of cell functions. In this study, we demonstrated the effects of ECMs on the differentiation of human bone marrow-derived MSCs into a smooth muscle cell (SMC) lineage. METHODS Human MSCs (hMSCs) were cultured on dishes coated with 3 types of ECM including laminin (LM), collagen type IV (Col-IV) and fibronectin for 7 days, and simultaneously cultured on a noncoated dish as a control. Cell numbers of these cultured hMSCs were counted, and their expression of SMC-specific genes and proteins was evaluated. hMSCs were then seeded on LM-coated biodegradable sheets and implanted into rat subcutaneous space. After 2 weeks of implantation, these tissues were evaluated. RESULTS The number of hMSCs was significantly increased by culture on Col-IV-coated dishes. The expression of SMC-specific genes and proteins (alpha-smooth muscle actin, ASMA; h1-calponin, CALP) in hMSC was significantly upregulated from culture on LM-coated dishes. LM-coated sheets showed a significantly increased expression of ASMA and CALP protein in vivo. Moreover, a fully differentiated marker (SM2) was expressed in the in vivo implanted hMSCs in the course of 2 weeks on the LM-coated sheet. CONCLUSION These results suggest that the signal transduction of the cell-matrix interaction for the differentiation of hMSCs into SMCs was activated when cultured with LM. LM-coated materials may thus be useful for cardiovascular tissue engineering.

Abstract
Bone-marrow-derived mesenchymal stem cells (MSCs) can differentiate into a variety of cell types including smooth muscle cells (SMCs). We have attempted to demonstrate that, following treatment with transforming growth factor-beta 1 (TGF-beta1) and ascorbic acid (AA), human bone-marrow-derived MSCs differentiate into the SMC lineage for use in tissue engineering. Quantitative polymerase chain reaction for SMC-specific gene (alpha smooth muscle actin, h1-calponin, and SM22alpha) expression was performed on MSCs, which were cultured with various concentrations of TGF-beta1 or AA. TGF-beta1 had a tendency to up-regulate the expression of SMC-specific genes in a dose-dependent manner. The expression of SM22alpha was significantly up-regulated by 30 microM AA. We also investigated the additive effect of TGF-beta1 and AA for differentiation into SMCs and compared this effect with that of other factors including platelet-derived growth factor BB (PDGF-BB). In addition to SMC-specific gene expression, SMC-specific proteins increased by two to four times when TGF-beta1 and AA were used together compared with their administration alone. PDGF did not increase the expression of SMC-specific markers. MSCs cultured with TGF-beta1 and AA did not differentiate into osteoblasts and adipocytes. These results suggest that a combination of TGF-beta1 and AA is useful for the differentiation of MSCs into SMCs for use in tissue engineering.

Abstract
PURPOSE To investigate the utilization of in-home services by severely mentally and physically handicapped persons at home in order to clarify the vital factors associated with the services. METHODS Questionnaires were delivered to 174 severely mentally and physically handicapped persons who were registered with 8 institutions in Tokyo and Kanagawa prefecture through each institution. One hundred and thirteen respondents among them were the subjects of this study. As a conceptual model Andersen's model was adopted. RESULTS (1) The age of subjects varied from 2 to 50. There were no subjects between the age of 7 to 17. The mean functional handicap severity score (SCORE) was 5.8 +/- 8.4 standard deviation. Ninety seven percent of main caregivers were mothers, even among the aged. (2) Over 1/2 of the subjects reported having utilized institutional services. On the other hand the percentage for visiting nurse service (VNS) and home help services were 28.3% and 7.7% respectively. (3) Subject who used V.N.S. had significantly higher SCORES and higher luck of health of caregivers. Caregivers utilized V.N.S. as a substitute to reduce their burden in activities care at home. On the other hand, users of institutional services showed high scores in difficulties with daily help and perceived difficulties with medical treatments: it showed that they sought institutional care to reduce there careburden. (4) Total number of used by each client for in-home service was explained only by both difficulties of daily help and SCORE from multiple regression analysis. CONCLUSION Users of visiting nursing service expect highquality care based on current medical knowledge and also with the aim of caregiver's health. With the increasing age of caregivers it appears to be important to enhance visiting nurse services, reduce the caregiver burden, and provide active support of home care for the handicapped.
