Abstract
INTRODUCTION Triple antiemetic therapy with neurokinin-1 receptor antagonist, 5-hydroxytryptamine type 3 receptor antagonist, and dexamethasone has been widely recommended for high emetogenic chemotherapeutic (HEC) agents and regimens, including anthracycline combined with cyclophosphamide (AC). The addition of olanzapine (OLZ) 5 mg or 10 mg to the recommended triple antiemetic therapy has demonstrated superiority in antiemetic efficacy compared with the standard triplet therapy for a cisplatin-based HEC regimen. Although OLZ plus the triple antiemetic treatment may also be effective for patients on an AC-based HEC regimen, no study has investigated its efficacy at a lower dose of 5 mg. METHODS AND ANALYSIS To assess whether 5 mg OLZ, as compared with placebo, in combination with triple combination therapy, significantly improves nausea and vomiting, we are conducting a randomised, parallel-group controlled clinical trial with a total of 500 patients at 15 study centres in Japan. The primary outcome is the complete response rate, defined as no emetic episodes and no use of rescue medication during 120 hours after the initiation of chemotherapy. Treatment group comparison for the primary endpoint will be done by using the Cochran-Mantel-Haenszel test. ETHICS AND DISSEMINATION The study was approved by the institutional review board of Juntendo University Hospital and relevant approval was obtained from all participating centres. All participants will be required to provide written informed consent. The trial results will be reported at conferences and in peer-reviewed journals. TRIAL REGISTRATION NUMBER Japan Registry of Clinical Trials (jRCT) jRCT1031200134; protocol date: 30 July 2020, version: 1.3, approval: 25 August 2020.

Abstract
Autism spectrum disorders (ASD) are associated with mutations of chromodomain-helicase DNA-binding protein 8 (Chd8) and tuberous sclerosis complex 2 (Tsc2). Although these ASD-related genes are detected in glial cells such as microglia, the effect of Chd8 or Tsc2 deficiency on microglial functions and microglia-mediated brain development remains unclear. In this study, we investigated the role of microglial Chd8 and Tsc2 in cytokine expression, phagocytosis activity, and neuro/gliogenesis from neural stem cells (NSCs) in vitro. Chd8 or Tsc2 knockdown in microglia reduced insulin-like growth factor-1(Igf1) expression under lipopolysaccharide (LPS) stimulation. In addition, phagocytosis activity was inhibited by Tsc2 deficiency, microglia-mediated oligodendrocyte development was inhibited, in particular, the differentiation of oligodendrocyte precursor cells to oligodendrocytes was prevented by Chd8 or Tsc2 deficiency. These results suggest that ASD-related gene expression in microglia is involved in oligodendrocyte differentiation, which may contribute to the white matter pathology relating to ASD.

Abstract
As a novel method of ivermectin (IVM) administration for the treatment of scabies, we devised a whole-body bathing (WBB), in which patients are immersed in a fluid that contains IVM. A multi-institutional trial for elderly patients with scabies was conducted to investigate the efficacy and safety of IVM-WBB. Seven elderly patients with scabies were enrolled and received IVM-WBB up to four times at 1-week interval. The cure for scabies was defined as the absence of mites in two consecutive microscopic or dermoscopic examinations at weekly intervals and the absence of new skin lesions indicative of scabies. Consequently, the cure rate on day 22, the primary end-point, was 71.4%, and all patients had been cured until day 29. Additionally, neither significant adverse events nor clinically problematic abnormal blood test values were obtained. Furthermore, no IVM was detected in the optional plasma (five cases) collected for IVM measurement after bathing. These results suggest that IVM-WBB was effective to treat scabies, causing no serious adverse events and with a very low internal exposure of IVM.

Abstract
'Academic Detailing' is an approach to providing doctors with information about medicines based on the latest non-commercial evidence-based data for proper prescription. Overseas, pharmacists have been active as academic detailers. Academic Detailing in Japan, as a new approach to disseminating comparative drug information based on basic pharmaceutical sciences and clinical evidence, will influence clinical decision making by doctors, and contribute to better patient-centered medical care. Pharmacists have been participating in ensuring the proper use of drugs by their patients by entering their homes or wards. However, in the future, it is necessary to take steps to improving pharmaceutical decision making by doctors. Therefore, we are considering the following educational points in the Japanese version of training an academic detailer. "A: We shall compare medicines based on basic pharmaceutical sciences and the latest non-commercial evidence-based data. B: We shall understand the point of using medicines based on the patient's condition. C: We shall choose cost-effective drugs from the viewpoint of pharmacoeconomics. And D: We shall acquire communication skills for effective academic detailing." In the future, this first class of Academic Detailers who facilitate academic detailing in the health care field will be pioneers. They will also participate in research to track and quantify the effects of academic detailing.

Abstract
BACKGROUND We have previously reported that human umbilical cord blood (UCB)-nucleated cells differentiate into hepatocyte-like cells when cultured in a 5-cytokine cocktail medium. We further found that UCB cells rather differentiated into dendritic-shaped cells by coculture with a human stellate cell (HSC) line, LI90. METHODS Monocytes from UCB and adult peripheral blood were cocultured with LI90 or rat primary HSCs in a cell-culture insert. Monocytes were also cultured with LI90-conditioned medium containing secreted factors, which were analyzed by a cytokine array. RESULTS In the coculture with LI90, resulting dendritic-shaped cells from monocytes expressed dendritic cell (DC) markers and activated allogeneic T cells, indicating that the dendritic-shaped cells were DCs. LI90 in the cytokine cocktail medium secreted various inflammatory factors, such as granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4. Fibroblast growth factor-2 in the cytokine cocktail was responsible for GM-CSF production from LI90 cells and for differentiation of monocytes into DCs in the LI90 coculture. Moreover, the coculture of monocytes with activated HSCs derived from damaged rat liver induced the differentiation of DCs, whereas quiescent HSCs derived from normal liver scarcely induced such a change. CONCLUSION These results suggest that activated HSCs are involved in differentiation of monocytes into DCs in the liver.

Abstract
Monkey embryonic stem (ES) cells have characteristics that are similar to human ES cells, and might be useful as a substitute model for preclinical research. When embryoid bodies (EBs) formed from monkey ES cells were cultured, expression of many hepatocyte-related genes including cytochrome P450 (Cyp) 3a and Cyp7a1 was observed. Hepatocytes were immunocytochemically observed using antibodies against albumin (ALB), cytokeratin-8/18, and alpha1-antitrypsin in the developing EBs. The in vitro differentiation potential of monkey ES cells into the hepatic lineage prompted us to examine the transplantability of monkey EB cells. As an initial approach to assess the repopulation potential, we transplanted EB cells into immunodeficient urokinase-type plasminogen activator transgenic mice that undergo liver failure. After transplantation, the hepatocyte colonies expressing monkey ALB were observed in the mouse liver. Fluorescence in-situ hybridization revealed that the repopulating hepatocytes arise from cell fusion between transplanted monkey EB cells and recipient mouse hepatocytes. In contrast, neither cell fusion nor repopulation of hepatocytes was observed in the recipient liver after undifferentiated ES cell transplantation. These results indicate that the differentiated cells in developing monkey EBs, but not contaminating ES cells, generate functional hepatocytes by cell fusion with recipient mouse hepatocytes, and repopulate injured mouse liver.

Abstract
BACKGROUND We previously reported that hepatocytes can be differentiated from embryonic stem (ES) cells by way of embryoid body (EB) formation and are transplantable into the mouse liver. However, the transplantation of EB-derived cells frequently resulted in teratoma formation in the recipient liver. In the present study, we eliminated the tumorigenic cells from EB outgrowths and examined the effects of enriched ES-cell-derived hepatocyte transplantation into an injured liver. METHODS On day 15 in culture, the EBs were partially disaggregated and subcultured. Hepatocytes in the subcultured cells were examined by the expression of hepatocyte markers. Undifferentiated cells contaminating in the EB-derived cells were eliminated by Percoll discontinuous gradient centrifugation. Furthermore, undifferentiated cells, endothelial cells, and macrophages were eliminated by magnetic cell sorting using platelet/endothelial cell adhesion molecule (PECAM)-1 and Mac-1 antibodies. These enriched ES-cell-derived hepatocytes were then transplanted into the injured mouse liver. RESULTS Percoll centrifugation and PECAM-1 antibodies eliminated the undifferentiated cells expressing Oct-3/4 from the EB-derived cells. ES-cell-derived hepatocytes showed expression of liver-related genes, synthesis of urea and glycogen, and structural characteristics during subculture. A transplantation study showed that the enriched ES-cell-derived hepatocytes integrated into the injured mouse liver and produced no teratomas. When the ES-cell-derived hepatocytes were transplanted into a CCl4-injured liver, the liver function was subsequently improved. CONCLUSIONS Functional hepatocytes can be differentiated from mouse ES cells by way of EB formation. The elimination of undifferentiated cells from the EBs provides transplantable cells for liver failure without tumorigenicity.
