Abstract
A young girl in her teens presented with fever, rashes and various mucocutaneous symptoms. Flat erythematous macules were seen mainly on the limbs, without blisters or skin detachments. The lips were swollen with crusts and haemorrhage. The oral cavity and pharynx showed ulcerative lesions with exudate. Severe bilateral ocular lesions with pseudomembrane formation and corneal epithelial defects were present. Also, urogenital lesion and gastrointestinal symptoms with frequent haematochezia were observed. Her symptoms and pathological findings were consistent with Stevens-Johnson syndrome. She was treated with prednisolone and methylprednisolone pulse therapy. Her ocular and cutaneous symptoms improved without severe chronic complications. However, 1 month later, she developed dyspnoea, and a pulmonary function test revealed severe obstructive ventilation disorder. After discharge, she was regularly followed up for respiratory complications. High-resolution chest CT performed 9 months after onset revealed mosaic perfusions and bronchiectasis, consistent with bronchiolitis obliterans.

Abstract
A 9-month-old girl presented with progressive abdominal distension. Imaging revealed a huge cystic mass in the left retroperitoneum with solid components. The right kidney was absent and hydrometrocolpos was found. Tumour drainage and complete surgical excision were performed. A bulge in the right side of the uterus, suggestive of a uterine anomaly, was seen on laparoscopic observation. Pathology was consistent with teratoma with a small portion of immature neural tissue. The patient was discharged in good condition and was advised regular follow-up.

Abstract
Very early-onset inflammatory bowel disease (VEO-IBD) and infantile IBD occur in children aged less than six years and less than two years, respectively. Since childhood-onset IBD seems to be a more aggressive and rapidly progressive disease than adult-onset IBD, it should therefore be diagnosed and treated immediately. Here, we report a case of infantile IBD in a three-month-old infant with clinical and biochemical manifestations. The diagnosis was confirmed with histopathological evidence. The patient had been treated successfully with both mesalazine and prednisolone and with mesalazine alone on follow-up.

Abstract
BACKGROUND Sweet's syndrome is characterized by fever, leukocytosis, and tender erythematous papules or nodules. It is a rare condition, particularly in the pediatric population, and has recently been proposed to be an autoinflammatory disease that occurs due to innate immune system dysfunction, involving several cytokines, which causes abnormally increased inflammation. To the best of our knowledge, no report has documented the cytokine profile in a pediatric patient with Sweet's syndrome. CASE PRESENTATION A previously healthy 34-month-old Japanese girl was hospitalized because of remittent fever and pain in her right lower extremity with erythematous nodules. A skin biopsy of the eruption revealed dermal perivascular neutrophilic infiltration with no evidence of vasculitis, which led to the diagnosis of Sweet's syndrome. She was prescribed with orally administered prednisolone and a prompt response was observed; then, the prednisolone dose was tapered. During treatment she developed upper and lower urinary tract infections, after which her cutaneous symptoms failed to improve despite increasing the prednisolone dosage. To avoid long-term use of systemic corticosteroids, orally administered potassium iodide was initiated, but it was unsuccessful. However, orally administered colchicine along with prednisolone effectively ameliorated her symptoms, and prednisolone dosage was reduced again. We analyzed the circulating levels of interleukin-1β, interleukin-6, interleukin-18, neopterin, and soluble tumor necrosis factor receptors I and II, in order to clarify the pathogenesis of Sweet's syndrome. Of these cytokines, only interleukin-6 levels were elevated prior to orally administered prednisolone therapy. Following therapy, the elevated interleukin-6 levels gradually diminished to almost normal levels; interleukin-1β and interleukin-18 stayed within normal ranges throughout the treatment. Neopterin became marginally elevated after the start of treatment. Both soluble tumor necrosis factor receptor I and soluble tumor necrosis factor receptor II levels increased shortly after the onset of urinary tract infections. CONCLUSIONS This is the first case report of pediatric Sweet's syndrome in which serum cytokine levels were investigated. Future studies should gather more evidence to elucidate the pathophysiology of Sweet's syndrome.

Abstract
Subcortical structures, which include the basal ganglia and parts of the limbic system, have key roles in learning, motor control and emotion, but also contribute to higher-order executive functions. Prior studies have reported volumetric alterations in subcortical regions in schizophrenia. Reported results have sometimes been heterogeneous, and few large-scale investigations have been conducted. Moreover, few large-scale studies have assessed asymmetries of subcortical volumes in schizophrenia. Here, as a work completely independent of a study performed by the ENIGMA consortium, we conducted a large-scale multisite study of subcortical volumetric differences between patients with schizophrenia and controls. We also explored the laterality of subcortical regions to identify characteristic similarities and differences between them. T1-weighted images from 1680 healthy individuals and 884 patients with schizophrenia, obtained with 15 imaging protocols at 11 sites, were processed with FreeSurfer. Group differences were calculated for each protocol and meta-analyzed. Compared with controls, patients with schizophrenia demonstrated smaller bilateral hippocampus, amygdala, thalamus and accumbens volumes as well as intracranial volume, but larger bilateral caudate, putamen, pallidum and lateral ventricle volumes. We replicated the rank order of effect sizes for subcortical volumetric changes in schizophrenia reported by the ENIGMA consortium. Further, we revealed leftward asymmetry for thalamus, lateral ventricle, caudate and putamen volumes, and rightward asymmetry for amygdala and hippocampal volumes in both controls and patients with schizophrenia. Also, we demonstrated a schizophrenia-specific leftward asymmetry for pallidum volume. These findings suggest the possibility of aberrant laterality in neural pathways and connectivity patterns related to the pallidum in schizophrenia.

Abstract
For years, HCs with zero ODP and low GWP have been used as alternative B.A. (blowing agents) in the appliance industries. The improvement of insulation performance and lowering costs are significant factors in the development of R-PU (rigid polyurethane) foams especially blown with HCs. The development of R-PU foam with a lower density for cost effectiveness is progressing at present. Positive experiences as to the long-term dimensional stability of pentane blown R-PU foam accelerated this movement. The most important factor in the development of R-PU foam with a lower density is long-term dimensional stability. In this report, we propose a novel long-term dimensional stability test and its appropriateness is discussed. The influence of formulation and the boiling point (B.P.) of B.A. on long-term dimensional stability have also been studied. The use of a blowing agent mixture of cyclopentane and iso- or n-pentane with a lower B.P. allowed the achievement of density savings. The understanding of the relation between the formulation and long-term dimensional stability is an important issue for the development of R-PU foam.

OBJECTIVES The present study sought to evaluate the effect of electrical stimulation (ES) by using kilohertz frequency on muscle atrophy induced by sepsis. METHODS Seventeen male ICR mice were randomly divided into 3 groups: control, lipopolysaccharide (LPS)-injected for 4 days, LPS plus ES (LPS+ES). Sepsis was induced by 4 days of an intraperitoneal LPS injection (10 μg/g body weight/day). LPS+ES animals received the LPS injections and ES twice a day for 4 days. ELISA and western blot analysis determined the plasma levels of inflammatory cytokines and ubiquitinated proteins, while the tibialis anterior muscles were weighed and muscle fiber cross-sectional area (CSA) were measured to assess muscle atrophy, which were analyzed by Student's t-test and ANOVA. RESULTS LPS induced increased plasma levels of inflammatory cytokines, significant muscle mass loss (LPS: -29.0%, LPS+ES: -23.1%), decreased fiber cross-sectional area, and an up-regulation of atrogin-1 and ubiquitinated proteins in the tibialis anterior muscle compared with the control. ES attenuated the sepsis-induced loss of muscle mass and decreased fiber CSA, as well as attenuated the atrogin-1 and ubiquitinated protein up-regulation. CONCLUSIONS Electrical stimulation may prevent sepsis-induced muscle atrophy through ubiquitin-proteasome pathway inhibition.

Abstract
We previously reported our data on telaprevir (TVR) used in combination with pegylated-interferon and ribavirin (PEG-IFN/RBV) for the treatment of recurrent hepatitis C virus (HCV) genotype 1 infection after liver transplantation (LT). TVR substantially increases the blood levels of immunosuppressive agents such as cyclosporine and tacrolimus for drug-drug interactions. On the other hand, the effect of simeprevir (SMV) on the blood levels of these immunosuppressive agents is unclear. We report 2 patients who achieved viral responses with little effect on the blood levels of cyclosporine and tacrolimus using SMV plus PEG-IFN/RBV treatment. The first was a 71-year-old woman with HCV-related liver cirrhosis and hepatocellular carcinoma who failed to respond to PEG-IFN/RBV after living donor LT. She was treated with 40 mg/d of cyclosporine, and received SMV plus PEG-IFN/RBV treatment. The second was a 65-year-old man with HCV-related liver cirrhosis who failed to respond to PEG-IFN/RBV after living donor LT. He was treated with 3 mg/d of tacrolimus, and received SMV plus PEG-IFN/RBV treatment. Serum HCV RNA became undetectable using TaqMan polymerase chain reaction (PCR) test after 4 weeks of treatment in both patients, and no remarkable fluctuation in blood concentration was observed either in cyclosporine or tacrolimus during the 12 weeks of SMV treatment. Completion of 12-week SMV triple therapy was followed by PEG-IFNα2b plus RBV, and both patients achieved sustained virological response 12 weeks after the end of treatment. SMV plus PEG-IFNRBV treatment showed a remarkable viral response with little effect on blood levels of immunosuppressive agents for recurrent HCV genotype 1 infection after LT.

Abstract
BACKGROUND Hepatoblastoma is a rare childhood malignant tumor that originates from immature hepatic cells. Aminopeptidase-N(CD13), an ectopeptidase that promotes tumor invasion and metastasis, is expressed in fetal stage hepatic progenitor cells, although its role in hepatoblastoma remains unclear. METHODS The expression pattern of CD13 was investigated on immunohistochemistry in 30 tissue samples from 27 hepatoblastoma patients (16 with predominantly embryonal [pE] histology and 14 with predominantly fetal [pF] histology). Immunoreactive score (IRS) was used to quantify staining data, and the relationship between CD13 expression, clinicopathological factors, and clinical outcome was investigated. The biological function of CD13 was also examined in the hepatoblastoma cell lines Huh6 and HepG2. RESULTS All specimens stained positive for CD13, with higher CD13 expression in pE than in pF hepatoblastoma samples (median IRS, 4; range, 2-9 vs 2; range, 1-4). Strong CD13 expression was correlated with vascular invasion. Five year event-free survival and overall survival were better in patients with CD13(low) than in those with CD13(high) tumors (100% vs 51.0%, P = 0.026; and 100% vs 74.0%, P = 0.114, respectively). A CD13-neutralizing antibody and the potent CD13 inhibitor, Ubenimex, suppressed invasive activity in HepG2 cells in vitro. CONCLUSIONS CD13 expression is associated with hepatoblastoma invasiveness and could be a novel prognostic marker for hepatoblastoma.

Abstract
A 14-year-old girl with multiple intra-abdominal tumors was diagnosed with stage III Burkitt's lymphoma. She achieved complete remission after multi-drug chemotherapy, but she relapsed after six courses. Autologous peripheral blood stem cells (PBSC) or allogeneic PBSC harvested from an HLA-identical sibling were insufficient, and her family did not agree to bone marrow collection from the sibling. Although the patient relapsed nine times (the relapses involved intra-abdominal organs or bone) during the following 4 years 7 months, treatment with rituximab monotherapy or in combination with ifosphamide, carboplastin, and etoposide, or local irradiation (33.8-40.0 Gy) to treat the bone metastases, proved effective, resulting in complete or partial remission. At the time of writing, the patient was in a 10th cycle of remission lasting 1 year 6 months and had not required transplantation. Thus, a chemotherapy regimen including rituximab might be effective for Burkitt's lymphoma in patients experiencing multiple relapse.

Abstract
BACKGROUND Transient receptor potential channel melastatin 8 (TRPM8) is activated by cold temperatures and cooling agents (menthol and icilin). Recent studies showed TRPM8 is expressed in visceral organs and peripheral sensory pathways. However, the role of TRPM8 in visceral hyperalgesia is poorly understood in pathological states such as inflammatory bowel disease. Hence, we investigated the distribution of TRPM8 and its involvement in visceral hyperalgesia in experimental colitis mice. METHODS TRPM8 immunoreactivity was detected using immunohistochemical staining with fluorescein-conjugated tyramide amplification. Visceral hyperalgesia was measured by the intracolonic administration of TRPM8 agonist, WS-12, in control and dextran sodium sulfate (DSS)-induced colitis mice. KEY RESULTS TRPM8 immunoreactivity in the distal colon was much higher than in the transverse and proximal colon under physiological conditions. TRPM8 immunoreactivity markedly increased in the distal colon mucosa of DSS-induced colitis mice compared with control mice. The number of TRPM8 nerve fibers in mucosa of DSS- or 2,4,6-trinitrobenzene sulfonic acid-induced colitis model mice drastically increased compared with control mice. TRPM8 immunoreactivities colocalized with the calcitonin gene-related peptide- and substance P-immunoreactive nerve fibers in the mucosa. Intracolonic administration of WS-12 induced behavioral visceral pain-like responses. The numbers of these responses in the colitis model mice were 3 times higher than in control mice, and were decreased by pretreatment with the TRPM8 channel blocker AMTB. CONCLUSIONS & INFERENCES Increased expression of TRPM8 may contribute to the visceral hyperalgesia of experimental colitis.

Abstract
IMTs belong to the group of soft tissue tumor and could occur at any anatomical site; however, the causes and growth feature remain unclear. This case report documents a 10-yr-old male suffering from slowly developing dyspnea on exertion and cough around seven months post-HCT. He was diagnosed with an endobronchial tumor based on imaging, and histology confirmed ALK-positive submucosal spindle-shaped cells with infiltrative cells, compatible with IMT. We should be aware that IMT is a potential complication of pediatric allogeneic HCT and can cause sudden airway obstruction.

Abstract
Certain physiological states and diseases can alter the expression and activity of cytochrome P450 s (CYPs), which have the potential to cause unexpected adverse effects. We previously demonstrated that lipopolysaccharide (LPS)-induced inflammation attenuates the induction of CYPs by xenobiotics in mouse liver. In this study, to investigate whether anaphylaxis-induced inflammation affects the hepatic CYPs' expression, we examined the effects of ovalbumin (OVA)-induced anaphylaxis on constitutive CYP mRNA and protein expressions. We also compared these effects with those obtained with LPS treatment. In addition, we examined the tumor necrosis factor (TNF) alpha and interleukin (IL)-113 mRNA levels, because these cytokines are known to be induced by LPS treatment and anaphylactic reactions. LPS treatment decreased the constitutively expressed Cyp1a2, Cyp2c29, and Cyp3al 1 mRNAs, and increased the TNFalpha and IL-1beta mRNAs. LPS treatment also decreased the CYP1A2 and CYP3A protein levels. Anaphylaxis, on the other hand, did not change the levels of the constitutively expressed Cyp1a2, Cyp2c29, or Cyp3a1 1 mRNAs, although it increased the TNFalpha and IL-1beta mRNAs, as observed in the LPS-treated mice. These results suggest that anaphylaxis-induced inflammation had less effect than LPS-induced inflammation on these CYPs in the liver. In contrast, we observed that the expressions of Cyp2b10 mRNA and its protein were quite different from those of the other CYPs in both the anaphylactic and LPS-treated mice. Our findings strongly suggest that the alteration of the constitutive CYPs' expression levels during inflammation varies according to the immunostimulation pathway.

Abstract
We investigated the preventive effects of nucleoprotein on capillary regression and mitochondrial dysfunction induced by unloading in the soleus muscle of rats. Nucleoprotein is a supplement made from soft roe of salmon, and its major components are nucleotides and protamine. Adult male Sprague-Dawley rats were divided randomly into control, hindlimb unloading (HU), and hindlimb unloading plus nucleoprotein administration (HU+ NP) groups. Hindlimb unloading was carried out for 2 weeks in the rats belonging to the HU and the HU+ NP groups. The rats of the HU+ NP group were administered nucleoprotein (500 mg/kg) using a feeding needle twice a day for 2 weeks. Hindlimb unloading resulted in capillary regression, decreased succinate dehydrogenase activity of the muscle fiber, and decreased PGC-1α expression in the soleus muscle. These effects were prevented by administration of nucleoprotein. Nucleoprotein appears to prevent capillary regression and mitochondrial dysfunction caused by unloading of the skeletal muscle. Therefore, nucleoprotein supplementation may be an effective therapy for maintaining capillary network and mitochondrial metabolism of the muscle fiber during an unloading period.

Abstract
The congenital dyserythropoietic anemias (CDAs) are a heterogeneous group of genetic disorders of red cell production. They are characterized by ineffective erythropoiesis and dyserythropoiesis. Here, we present the clinical description and mutation analysis of a Japanese female with CDA type 1. She has long been diagnosed with unclassified congenital hemolytic anemia from the neonatal period. However, bone marrow morphology and genetic testing of the CDAN1 gene at the age of 12 years confirmed the afore-mentioned diagnosis. Thus, we should be aware of the possibility of CDA if the etiology of congenital anemia or jaundice cannot be clearly elucidated.

Abstract
AIM The capillary regression in skeletal muscles associated with a chronic decrease in activity is related to a dysfunction of endocapillary cells induced by over-expression of oxidative stress. We hypothesized that treatment with astaxanthin, an antioxidant, would attenuate the oxidative stress induced by decreased skeletal muscle use, and that this attenuation would prevent the associated capillary regression. The purpose of the present study was to investigate the antioxidant and preventive effects of astaxanthin on capillary regression in the soleus muscle during hindlimb unloading. METHODS Twenty-four adult male Wistar rats were assigned randomly either to a control, control plus astaxanthin treatment, hindlimb unloaded or hindlimb unloaded plus astaxanthin treatment group for 7 days. RESULTS Hindlimb unloading resulted in a decrease in mean soleus absolute weight, capillary number, volume and luminal diameter. The accumulation of reactive oxygen species and the over-expression of superoxide dismutase (SOD-1), a decrease in the levels of vascular endothelial growth factor (VEGF) and its receptors, an inhibition of the angiopoietin pathway and an increase of thrombospondin-1 (TSP-1), as an anti-angiogenic factor were showed. Administration of astaxanthin attenuated the changes in SOD-1 and VEGF, up-regulated the angiogenic factors and reduced the capillary regression in the soleus of hindlimb unloaded rats. In addition, the VEGF-to-TSP1 ratio was higher in the astaxanthin treated groups than in the control and HU groups. CONCLUSION These results suggest that astaxanthin may be an effective treatment to counter the detrimental effects of a chronic decrease in skeletal muscle use on the capillary network and associated angiogenic pathways.

Abstract
In acute lymphoblastic leukemia (ALL) patients, the bone marrow niche is widely known to be an important element of treatment response and relapse. Furthermore, a characteristic liver pathology observed in ALL patients implies that the hepatic microenvironment provides an extramedullary niche for leukemic cells. However, it remains unclear whether the liver actually provides a specific niche. The mechanism underlying this pathology is also poorly understood. Here, to answer these questions, we reconstituted the histopathology of leukemic liver by using patients-derived primary ALL cells into NOD/SCID/Yc (null) mice. The liver pathology in this model was similar to that observed in the patients. By using this model, we clearly demonstrated that bile duct epithelial cells form a hepatic niche that supports infiltration and proliferation of ALL cells in the liver. Furthermore, we showed that functions of the niche are maintained by the SDF-1/CXCR4 axis, proposing a novel therapeutic approach targeting the extramedullary niche by inhibition of the SDF-1/CXCR4 axis. In conclusion, we demonstrated that the liver dissemination of leukemia is not due to nonselective infiltration, but rather systematic invasion and proliferation of leukemic cells in hepatic niche. Although the contribution of SDF-1/CXCR4 axis is reported in some cancer cells or leukemic niches such as bone marrow, we demonstrated that this axis works even in the extramedullary niche of leukemic cells. Our findings form the basis for therapeutic approaches that target the extramedullary niche by inhibiting the SDF-1/CXCR4 axis.

Abstract
Induced pluripotent stem (iPS) cells are of potential value not only for regenerative medicine, but also for disease investigation. The present study describes the development of a neutrophil differentiation system from human iPS cells (hiPSCs) and the analysis of neutrophil function and differentiation. The culture system used consisted of the transfer of hiPSCs onto OP9 cells and their culture with vascular endothelial growth factor (VEGF). After 10 days, TRA 1-85(+) CD34(+) VEGF receptor-2 (VEGFR-2)(high) cells were sorted and co-cultured with OP9 cells in the presence of hematopoietic cytokines for 30 days. Floating cells were collected and subjected to morphological and functional analysis. These hiPSC-derived neutrophils were similar to peripheral blood mature neutrophils in morphology, contained functional neutrophil specific granules, and were equipped with the basic functions such as phagocytosis, superoxide production, and chemotaxis. In the process of differentiation, myeloid cells appeared sequentially from immature myeloblasts to mature segmented neutrophils. Expression patterns of surface antigen, transcription factors, and granule proteins during differentiation were also similar to those of granulopoiesis in normal bone marrow. In conclusion, differentiation of mature neutrophils from hiPSCs was successfully induced in a similar process to normal granulopoiesis using an OP9 co-culture system. This system may be applied to elucidate the pathogenesis of various hematological diseases that affect neutrophils.

Abstract
A 6-year-old male with chronic granulomatous disease, who was transplanted with bone marrow and exhibited increasing mixed chimerism, subsequently received two donor lymphocyte infusions (DLI). Two weeks after the second DLI, the patient developed acute graft-versus-host disease (GVHD) and progressive pancytopenia that was associated with autoantibody production. Conventional treatment did not improve the pancytopenia. However, administration of Rituximab (RTX) (375 mg/m(2)/week for four consecutive weeks) resulted in a rapid resolution of the pancytopenia. The patient achieved full donor chimerism without GVHD symptoms. RTX can be valuable for managing immune-mediated cytopenias that arise after DLI and are refractory to conventional therapies.

Abstract
The objectives of this study are to clarify (1) the difference in demographic and clinical variables at initial presentation between acute and chronic idiopathic thrombocytopenic purpura (ITP), and (2) the prognostic factors of patients with chronic ITP. We conducted a retrospective analysis of 247 children with newly diagnosed ITP between April 1991 and March 2006 who visited one of the 12 hospitals belonging to the Kyoto University Pediatric Hematologic Study Group. 180 and 67 cases were classified as the acute type and as the chronic type, respectively. Older age, higher initial platelet count, positive medical history or concomitant medical diagnosis, the absence of preceding infection or vaccination, and the absence of an increase in immunoglobulin were risk factors for the chronicity. The prognostic factors in chronic ITP were evaluated in 53 patients after excluding patients receiving splenectomy or having insufficient follow-up data. The overall time required for 50% resolution in patients with chronic ITP was approximately 5.6 years. Age at presentation of less than 3 years and higher platelet counts at the time of chronic ITP diagnosis were good prognostic factors. On the other hand, gender, initial platelet counts, and preceding infection or vaccination were not associated with the prognosis.

Abstract
To investigate the events leading to the depletion of CD4(+) T lymphocytes during long-term infection of human immunodeficiency virus type 1 (HIV-1), we infected human CD34(+) cells-transplanted NOD/SCID/IL-2Rgamma(null) mice with CXCR4-tropic and CCR5-tropic HIV-1. CXCR4-tropic HIV-1-infected mice were quickly depleted of CD4(+) thymocytes and both CD45RA(+) naïve and CD45RA(-) memory CD4(+) T lymphocytes, while CCR5-tropic HIV-1-infected mice were preferentially depleted of CD45RA(-) memory CD4(+) T lymphocytes. Staining of HIV-1 p24 antigen revealed that CCR5-tropic HIV-1 preferentially infected effector memory T lymphocytes (T(EM)) rather than central memory T lymphocytes. In addition, the majority of p24(+) cells in CCR5-tropic HIV-1-infected mice were activated and in cycling phase. Taken together, our findings indicate that productive infection mainly takes place in the activated T(EM) in cycling phase and further suggest that the predominant infection in T(EM) would lead to the depletion of memory CD4(+) T lymphocytes in CCR5-tropic HIV-1-infected mice.

Abstract
To gain a better understanding of the metabolic properties between the open acid and lactone form of HMG-CoA reductase inhibitors (statins), the paper focused primarily on characterizing the metabolic properties of statins. We compared the metabolism of the acid and lactone forms of several statins, including atrovastatin, simvastatin, cerivastatin fluvastatin, pitavastatin and rosuvastatin with respect to metabolic clearance, CYP enzymes involved and drug-drug interactions. A remarkable increase in metabolic clearance was noted for all lactones compared with all acids except for pitavastatin lactone. The metabolic clearances of the atrovastatin, simvastatin, cerivastatin, fluvastatin and rosuvastatin lactones were 73-, 70-, 30-, 7- and 64-fold higher, respectively, than those of the corresponding acids. CYP2Cs were critically involved in the metabolism of cerivastatin, fluvastatin and pitavastatin acids. In contrast, CYP2Cs were not involved in the metabolism of the corresponding lactones and CYP3A4 was mainly involved. Moreover, a substantial difference in the metabolic inhibition of statins was found between acids and lactones. Overall, the study demonstrates that CYP-mediated metabolism of lactones is also a common metabolic pathway for statins and that the CYP3A4-mediated metabolism of the lactone forms clearly will need to be taken into account in assessing mechanistic aspects of drug-drug interaction involving statins.

Abstract
The monkey is often used to predict metabolism of drugs in humans since it generally shows a metabolic pattern similar to humans. However, metabolic profiles different from humans are occasionally seen in monkeys for some drugs including pitavastatin. Recently, we have successfully identified a monkey-specific cytochrome P450 (CYP) 2C76, which possibly accounts for a species difference between monkeys and humans because of its sequence and functional uniqueness. The present study on the role of CYP2C76 and other monkey CYP2Cs in pitavastatin metabolism, as an example, has revealed that CYP2C76 is important for the metabolism of the lactone form, indicating a major role of CYP2C76 for the difference in the metabolism of pitavastatin and possibly other drugs between monkeys and humans. The current investigation on the involvement of CYP2C76 in the metabolism of other drugs is expected to reveal further the further importance of this monkey-specific drug-metabolizing enzyme.

Abstract
OBJECTIVES To evaluate the efficacy of gamma knife surgery (GKS) for the control of peritumoral oedema associated with metastatic brain tumours. METHODS A retrospective study of 280 consecutive metastatic brain tumours-100 from lung cancers, 100 from breast cancers and 80 from renal-cell carcinomas, associated with peritumoral oedema. The peritumoral oedema index was measured as A*B*C, where A (cm) was the maximum diameter of peritumoral oedema on the axial image, B (cm) was the maximum diameter perpendicular to A, and C (cm) was the maximum diameter on the coronal image. RESULTS The oedema index of the renal cancer metastases was significantly larger than those of lung and breast cancer metastases (p<0.01). The oedema index of the renal cancer metastases at final imaging was also larger than those of lung (p<0.05) and breast (p<0.01) cancer metastases. The delivered marginal dose (22 Gy or more) was significantly correlated with tumour growth control by multivariate analysis (p = 0.03). Primary site (renal or not renal: p<0.01) and delivered marginal dose (25Gy or more: p = 0.04) were significantly correlated with control of peritumoral oedema by multivariate analysis. CONCLUSIONS Brain oedema around metastatic brain tumours from renal-cell carcinomas was more extensive at the time of GKS and at final imaging compared with lung and breast cancer metastases. This paper suggests that the optimal doses for tumour growth control and brain oedema control may differ for metastatic brain tumours from renal-cell carcinomas.

Abstract
BACKGROUND We evaluated the clinical characteristics of microsurgery for vestibular schwannoma (VS) after failed gamma knife radiosurgery (GKS). METHOD Twelve patients, 5 men and 7 women aged 19 to 70 years (mean 54.5 years), who underwent microsurgery after failed GKS for VS were studied retrospectively. FINDINGS The median interval between GKS and microsurgery was 28.8 months (range, 6.6-120 months) and 4 patients had undergone previous microsurgery. The mean volume of tumour at GKS was 6.9 cm(3) (range, 0.5-19.7 cm(3)) and the mean prescription dose to the tumour margin was 12.3 Gy. Microsurgery involved the lateral suboccipital approach in all patients. Tumour expansion involved solid enlargement in 7 patients, cystic enlargement in 3, and central necrosis in 2. Bleeding was slight in all patients except in one, probably because of the previous irradiation. Adhesion to the brain stem was severe in 7 patients. Identification of the facial nerve was easy in 5 operations and difficult in 7. Dissection of the tumour from the facial nerve was difficult in most interventions because of severe adhesions or colour change. Severe adhesions between the trigeminal nerve and the tumour was observed in 2 patients. The tumour was subtotally removed except around the internal auditory canal in most patients. Only one residual tumour increased in size and needed second GKS. The function of the facial nerve deteriorated in 3 patients, was unchanged in 7, and improved in 2. All patients had lost hearing on the affected side at the time of microsurgery. CONCLUSIONS Microsurgery for VS after failed GKS presents some technical difficulties. Dissection of the tumour from the facial nerve or brain stem is likely to be difficult. We recommend subtotal resection without dissection of the facial nerve and tumour, because growth of the residual tumour was rare in our series.

Abstract
Clinical features, brain magnetic resonance imaging findings and EDSS scores of 11 patients with neurodegenerative central nervous system Langerhans cell histiocytosis were analyzed in Japan. All patients initially had multi-system-type Langerhans cell histiocytosis; 8 at 1-2 years of age and 3 at a later age. Neurodegenerative central nervous system Langerhans cell histiocytosis disease developed after a median time interval of 3.9 years from initial diagnosis. With a median follow-up of 4.5 years, 6 patients showed progression of disease with an EDSS score >3. This study demonstrates the importance of early detection of neurodegenerative central nervous system Langerhans cell histiocytosis by brain magnetic resonance imaging, particularly in the follow-up of patients who developed multi-system-type Langerhans cell histiocytosis in early infancy.

Abstract
Conditions that influence the selective development or recruitment of connective tissue-type and mucosal-type mast cells (MCs) are not well understood. Here, we report that cynomolgus monkey embryonic stem (ES) cells cocultured with the murine aorta-gonad-mesonephros-derived stromal cell line AGM-S1 differentiated into cobblestone (CS)-like cells by day 10-15. When replated onto fresh AGM-S1 with the addition of stem cell factor, interleukin-6, and Flt3 ligand, these CS-like cells displayed robust growth and generated almost 100% tryptase/chymase double-positive MCs within 3 weeks. At all time points, the percentage of tryptase-positive cells did not exceed that of chymase-positive cells. These ES-derived MCs were CD45+/Kit+/CD31+/CD203c+/HLA-DR- and coexpressed a high-affinity IgE receptor on their surface, which was upregulated after IgE exposure. Electron microscopy showed that they contained many electron dense granules. Moreover, ES-derived MCs responded to stimulation by via IgE and substance P by releasing histamine. These results indicate that ES-derived MCs have the phenotype of functionally mature connective tissue-type MCs. The rapid maturation of ES-derived MCs suggests a unique embryonic pathway in primates for early development of connective tissue-type MCs, which may be independent from the developmental pathway of mucosal-type MCs.

Abstract
Bedridden patients who receive good physical rehabilitation are able to exhibit clinical improvement. Accumulating evidence demonstrates that exercise increases endogenous neurogenesis and may even protect against central nervous system (CNS) disorders. Here, we explored the effects of lack of exercise on neurogenesis in rats by employing a routine hindlimb suspension (HS) model over a 2-week period, which consists of elevating their tails, thereby raising their hindlimbs above the ground and unloading the weights in these extremities. In addition, the effects of exercise and recovery time with normal caging after HS were also explored. BrdU (50 mg/kg, i.p.) was injected every 8 h over the last 4 days of each paradigm to label proliferative cells. Immunohistochemical results revealed that HS significantly reduced the number of BrdU/Doublecortin double-positive cells in the subventricular zone and dentate gyrus. Exercise and recovery time significantly improved atrophy of the soleus muscle, but did not attenuate the HS-induced decrement in BrdU/Dcx-positive cells. A separate cohort of animals was exposed to the same HS paradigm and enzyme-linked immunosorbent assay (ELISA) of neurotrophic factors was performed on brain tissue samples harvested at the end of the HS period, as well as plasma samples from all animals. ELISA results revealed that HS reduced the levels of brain-derived neurotrophic factor in the hippocampus and vascular endothelial growth factor plasma levels. This study revealed that lack of exercise reduced neurogenesis with downregulation of neurotrophic factors. The use of the HS model in conjunction with CNS disease models should further elucidate the role of exercise in neurogenesis and neurotrophic factors in neurologic disorders.

Abstract
BACKGROUND The results of gamma knife radiosurgery for haemangioblastomas were retrospectively studied to assess the efficacy for tumour growth control and clarify the clinical indications for gamma knife radiosurgery in these tumours. METHODS The medical records of 22 patients with 67 tumours, 12 men and 10 women aged 20-73 years (mean 51.9 years), who underwent gamma knife radiosurgery for haemangioblastomas between January 1993 and January 2006, were retrospectively reviewed. Ten patients with 54 lesions had von Hippel-Lindau disease. The mean tumour volume was 1.69 cm(3) (range 0.0097-16.4 cm(3)). Nineteen patients had undergone 1-4 open surgery procedures (mean 1.5) before gamma knife radiosurgery. Tumours without a cystic component, (the solid type), were found in 54 lesions and tumours associated with cyst, (the mural nodule with cyst type), in 13 lesions. The marginal dose was 8-30 Gy (mean 14.0 Gy). FINDINGS Follow-up magnetic resonance (MR) imaging was performed at 9-146 months (mean 63 months). The control rate for tumour growth was 83.6%. The only factor affecting tumour growth control was the presence of a cystic component at the time of gamma knife radiosurgery in both univariate and multivariate analysis. No complication such as radiation-induced peritumoural oedema or radiation necrosis occurred. CONCLUSION The presence of cystic components at the time of gamma knife radiosurgery was the only factor significantly correlated with unfavourable tumour growth control by gamma knife radiosurgery for haemangioblastomas. Gamma knife radiosurgery is effective for solid type tumours, even if the marginal dose is relatively low. Surgical removal is recommended for mural nodule with cyst type tumours, when possible.

Abstract
Several studies have shown that hepatocytes can be generated from hematopoietic stem cells, but this event is believed to be rare and to require hepatic damage. To investigate this phenomenon in human cells, we used a NOD/SCID/gamma(c)null (NOG) mouse model that can achieve a tremendously high level of chimerism when transplanted with human hematopoietic cells. Even without hepatotoxic treatment other than irradiation, human albumin and alpha-1-antitrypsin-positive cells were invariably detected in the livers of NOG mice after i.v. transplantation of human cord blood CD34+ cells. Human albumin was detected in the murine sera, indicating functional maturation of the human hepatocytes. Flow cytometric analysis of recipient liver cells in single-cell suspension demonstrated that human albumin-positive cells were also positive for both murine and human MHC and were negative for human CD45. PCR analysis of recipient livers revealed the expression of a wide variety of human hepatocyte- or cholangiocyte-specific mRNAs. These results show that human CD34+ cells fuse with hepatocytes of NOG mice without liver injury, lose their hematopoietic phenotype, and begin hepatocyte-specific gene transcription. These phenomena were not observed when CD34- cells were transplanted. Thus, our model revealed a previously unidentified pathway of human hematopoietic stem/progenitor cell differentiation.

Abstract
To investigate the contribution of genetic polymorphisms of SLCO1B1 and ABCG2 to the pharmacokinetics of a dual substrate, pitavastatin, 2 mg of pitavastatin was administered to 38 healthy volunteers and pharmacokinetic parameters were compared among the following groups: 421C/C(*)1b/(*)1b (group 1), 421C/C(*)1b/(*)15 (group 2), 421C/C(*)15/(*)15 and 421C/A(*)15/(*)15 (group 3), 421C/A(*)1b/(*)1b (group 4), 421A/A(*)1b/(*)1b (group 5), and 421C/A(*)1b/(*)15 (group 6). In SLCO1B1, pitavastatin area under plasma concentration-time curve from 0 to 24 h (AUC(0-24)) for groups 1, 2, and 3 was 81.1+/-18.1, 144+/-32, and 250+/-57 ng h/ml, respectively, with significant differences among all three groups. In contrast to SLCO1B1, AUC(0-24) in groups 1, 4, and 5 was 81.1+/-18.1, 96.7+/-35.4, and 78.2+/-8.2 ng h/ml, respectively. Although the SLCO1B1 polymorphism was found to have a significant effect on the pharmacokinetics of pitavastatin, a nonsynonymous ABCG2 variant, 421C>A, did not appear to be associated with the altered pharmacokinetics of pitavastatin.

Abstract
Sphere formation has been utilized as a way to isolate multipotent stem/progenitor cells from various tissues. However, very few studies on bone marrow-derived spheres have been published and assessed their multipotentiality. In this study, multipotent marrow cell populations were isolated using a three-step method. First, after elimination of hematopoietic cells, murine marrow-derived adherent cells were cultured in plastic dishes until small cells gradually appeared and multiplied. Cells were then cultured under non-adherent conditions and formed spheres that were immunopositive for a neural precursor marker, nestin. RT-PCR analysis also revealed that the spheres were positive for nestin in addition to PPARgamma, osf2, SOX9, and myoD, which are markers of precursors of adipocytic, osteoblastic, chondrocytic, and skeletal myeloblastic lineages, respectively. Finally, spheres were dissociated into single cells and expanded in adherent cultures. Under appropriate induction conditions, the sphere-derived cells acquired the phenotypic properties in vitro of neurons, skeletal myoblasts, and beating cardiomyocytes, as well as adipocytes, osteoblasts, and chondrocytes. Next, sphere-derived cells were transplanted into murine myocardial infarction models. One month later, they had become engrafted as cardiomyocytes, and cardiac catheterization showed significant functional improvements. Thus, sphere-derived cells represent a new approach to enhance the multi-differentiation potential of murine bone marrow.

Abstract
Few studies on the long-term culture of postnatal mouse hepatic stem/progenitor cells have been reported. We successfully adapted a serum-free culture system that we employed previously to expand fetal mouse hepatic stem/progenitor cells and maintained them in culture over long periods. The expanded postnatal cells contained immature alpha-fetoprotein-positive cells along with hepatocytic and cholangiocytic lineage-committed cells. These cells expressed CD49f but not CD45, CD34, Thy-1, c-kit, CD31, or flk-1, and oncostatin M induced their differentiation. This heterogeneous population contained side population (SP) cells, which express the ATP-binding cassette transporter ABCG2, and sca-1+ cells. As mice aged, the frequency of SP and sca-1+ cells decreased along with the ability of cultured cells to expand. Approximately 20%-40% of the SP cells expressed sca-1, but only a few sca-1+ cells were also SP cells. Analysis of colonies derived from single SP or sca-1+ cells revealed that, although both cells had dual differentiation potential and self-renewal ability, SP cells formed colonies more efficiently and gave rise to SP and sca-1+ cells, whereas sca-1+ cells generated only sca-1+ progeny. Thus, SP cells are more characteristic of stem cells than are sca-1+ cells. In regenerating livers, ABCG2+ cells and sca-1+ cells were detected around or in the portal area (the putative hepatic stem cell niche). The expanded cells share many features of fetal hepatic stem/progenitor cells or oval cells and may be useful in determining the mechanisms whereby hepatic stem cells self-renew and differentiate.

Abstract
STUDY DESIGN Retrospective study of the degree of gait independence achieved by persons with spinal cord injury (SCI) using knee-ankle-foot orthosis with a medial single hip joint (MSH-KAFO). OBJECTIVE To examine the effects of the neurological level, degree of paresis, age, and inhibitory physical/other factors on the gait with a MSH-KAFO in patients with SCIs. SETTING Three university hospitals and two rehabilitation hospitals in Japan. METHODS The 45 patients (36 men, nine women) examined included 10 with injuries in the cervical cord between C6 and C8 (group C), 20 with injuries in the upper-middle thoracic cord between T4 and T10 (group UT), and 15 with injuries in the lower thoracic-lumbar cord between T12 and L1 (group TL). Mean age was 34.0 years (range 16-68 years). Of these patients, 13 used the Walkabout, four used the gear joint, and 28 used the Primewalk as the medial hip joint. Recursive partitioning, which predicted the final status of gait from the level, degree of paresis, age, and inhibitory factors, was performed, and a decision tree for gait was constructed. Inhibitory factors were spasticity, involuntary spasms or muscle contractions, pain, contracture, weakness of the upper extremities, and decreased motivation to perform gait exercise. The degree of gait independence was rated on the following five-point scale: outdoor independent gait (5 points), indoor independent gait (4 points), indoor supervised gait (3 points), indoor assisted gait (2 points), and gait within parallel bars (1 point). New branches were added to the decision tree for gait based on the clinical experience, thereby constructing a new decision tree. RESULTS The coincident ratio between the value predicted on the basis of the decision tree of gait and the value actually observed was 53.3%. The coincident ratio between the value predicted on the basis of the modified decision tree of gait and the actually observed value was 68.9%. CONCLUSION The results provide valuable information to medical teams that may assist prescription of gait orthoses.

Abstract
A positive association between vascular endothelial growth factor-C (VEGF-C) expression and lymph node metastasis has been reported in several cancers. However, the relationship of VEGF-C and lymph node metastasis in some cancers, including non-small cell lung cancer (NSCLC), is controversial. We evaluated the VEGF-C and vascular endothelial growth factor receptor-3 (VEGFR-3) expression in NSCLC samples from patients who had undergone surgery between 1998 and 2002 using real-time quantitative RT–PCR and immunohistochemical staining. We failed to find a positive association between VEGF-C and VEGFR-3 mRNA expression and lymph node metastasis in NSCLC. An immunohistological study demonstrated that VEGF-C was expressed not only in cancer cells, but also in macrophages in NSCLC, and that VEGFR-3 was expressed in cancer cells, macrophages, type II pneumocytes and lymph vessels. The VEGF-C/VEGFR-3 ratio of the node-positive group was significantly higher than that of the node-negative group. Immunohistochemical staining showed that VEGFR-3 was mainly expressed in cancer cells. The immunoreactivity of VEGF-C and VEGFR-3 was roughly correlated to the mRNA levels of VEGF-C and VEGFR-3 in real-time PCR. VEGF-C mRNA alone has no positive association with lymph node metastasis in NSCLC. The VEGF-C/VEGFR-3 ratio was positively associated with lymph node metastasis in NSCLC. This suggests that VEGF-C promotes lymph node metastasis while being influenced by the strength of the VEGF-C autocrine loop, and the VEGF-C/VEGFR-3 ratio can be a useful predictor of lymph node metastasis in NSCLC.
