Abstract
We report the case of a 66-year-old woman who presented with diarrhea and weight loss approximately 14 months after unrelated allogeneic bone marrow transplantation for acute myeloid leukemia. Her early post-transplant course was notable for mild acute skin graft-versus-host disease (GVHD) and biopsy-proven upper gastrointestinal (GI) acute GVHD, both of which resolved with treatment. She then developed weight loss and diarrhea treated with prednisolone for what was thought to be GI late acute GVHD. However, her diarrhea and weight loss persisted. Colonoscopy showed a grossly intact mucosa, and stool studies only confirmed steatorrhea. However, an atrophic pancreas was found on an abdominal computed tomography (CT) scan. Exocrine pancreatic enzymes, such as lipase and pancreatic amylase, were markedly decreased, yet pancreatic endocrine function remained intact. The patient's diarrhea and weight loss improved upon treatment with pancrelipase. Therefore, we suggest that her exocrine pancreatic insufficiency was likely partly caused by atypical chronic GVHD.

Abstract
Cardiotoxicity is a critical complication of allogeneic hematopoietic cell transplantation (allo-HCT). In particular, management of severe cardiotoxicity occurring in the early phases of allo-HCT is challenging. We encountered a case of severe cardiotoxicity resulting from AHF six days after allo-HCT, which resisted catecholamines and diuretics. The patient was treated with anthracycline-containing regimens and underwent myeloablative conditioning, including high-dose cyclophosphamide. As invasive circulatory assisting devices were contraindicated because of his immunocompromised status and bleeding tendency, we successfully treated the patient with ivabradine-containing medications. Ivabradine may therefore be considered an alternative drug for the treatment of severe cardiotoxicity induced by cytotoxic agents.

Abstract
We report the case of a 28-year-old woman who developed upper abdominal pain and jaundice after a second unrelated allogeneic hematopoietic cell transplantation (allo-HCT) for acute lymphoid leukemia (ALL). Laboratory data showed elevated levels of liver enzymes, amylase, and lipase. Although acute pancreatitis was suspected, no structural lesions were detected. Liver biopsy was compatible with late-onset acute graft-versus-host disease (GVHD), which resolved following treatment with methylprednisolone (mPSL) and tacrolimus (TAC). In addition, her serum amylase level and abdominal pain rapidly resolved following acute GVHD-directed therapy. Acute pancreatitis concomitant with late-onset acute liver GVHD is extremely rare and has not been documented subsequent to a second allo-HCT.

Abstract
Background Chronic myeloid leukemia is a hematologic malignancy associated with the fusion of two genes: BCR and ABL1. This fusion results from a translocation between chromosomes 9 and 22, which is called the Philadelphia chromosome. Although the Philadelphia chromosome is present in more than 90% of patients with chronic myeloid leukemia, 5–8% of patients with chronic myeloid leukemia show complex variant translocations. Herein, we report a unique case of a three-way translocation variant in chronic phase chronic myeloid leukemia. Case presentation A 40-year-old Asian male who presented with leukocytosis was diagnosed with chronic phase chronic myeloid leukemia. Cytogenetic karyotyping analysis showed 46,XY,t(4;9;22)(q21;q34;q11.2). He was treated with bosutinib and then changed to dasatinib because of intolerance, and MR4.5 (BCR-ABL/ABL ≦ 0.0032%, international scale) was achieved after 17 months of continuous treatment. Conclusion This was the 14th case of t(4;9;22), in particular, a new variant Ph translocation involved in chromosome 4q21 and the first successful case treated with tyrosine kinase inhibitors in the world. We summarize previous case reports regarding three-way variant chromosome translocation, t(4;9;22) and discuss how this rare translocation is linked to prognosis.

Abstract
A 67-year-old man was diagnosed with a submucosal primary gastric T-cell lymphoma (PGTL) via upper gastroenteroscopy following an annual health check-up. He received six cycles of CHOP and achieved a complete remission. However, the patient relapsed 4 months post therapy. A second remission, which was maintained for years, was achieved after surgical gastrectomy followed by adjuvant chemotherapies. Prior reports have shown that surgery combined with chemotherapies was curative for patients with newly-diagnosed PGTL. In this report, surgery combined with chemotherapies was successfully applied for early-relapsed PGTL.

Abstract
Acquired factor V deficiency (AFVD) is a rare autoimmune bleeding disorder. Unlike acquired hemophilia, bypass therapies with recombinant activated factor VII and activated prothrombin complex concentrates are ineffective for severe bleeding due to AFVD. Although several treatment strategies have been attempted, a standard of care for severe hemorrhage induced by AFVD is lacking. Herein, we report a case of AFVD with severe bleeding that responded to plasma exchange (PE) combined with immunosuppression. We also reviewed previously reported AFVD cases with severe hemorrhage and suggest that PE may be an effective initial treatment for AFVD-induced severe hemorrhage.

Abstract
Fast ignition (FI) is a promising approach for high-energy-gain inertial confinement fusion in the laboratory. To achieve ignition, the energy of a short-pulse laser is required to be delivered efficiently to the pre-compressed fuel core via a high-energy electron beam. Therefore, understanding the transport and energy deposition of this electron beam inside the pre-compressed core is the key for FI. Here we report on the direct observation of the electron beam transport and deposition in a compressed core through the stimulated Cu Kα emission in the super-penetration scheme. Simulations reproducing the experimental measurements indicate that, at the time of peak compression, about 1% of the short-pulse energy is coupled to a relatively low-density core with a radius of 70 μm. Analysis with the support of 2D particle-in-cell simulations uncovers the key factors improving this coupling efficiency. Our findings are of critical importance for optimizing FI experiments in a super-penetration scheme.

Abstract
A 70-year-old man having a mass lesion on his right lower abdomen for 2 months was admitted to our hospital for diagnosis. Upon admission, the patient experienced bilateral upper and lower limb weakness, which aggravated. He underwent nerve conduction study and was diagnosed with axonal neuropathy. Diagnosis of diffuse large B-cell lymphoma (DLBCL) was accomplished via biopsy of the mass lesion, with positive laboratory tests for anti-ganglioside antibodies. Based on these results, immune-mediated DLBCL-induced polyneuropathy was suspected, and chemotherapy (R-CHOP) was immediately started. Limb weakness improved and completely resolved. After six courses of R-CHOP, no evidence of DLBCL was observed on PET/CT (i.e., complete metabolic remission). The patient lived without DLBCL relapse or neurological symptoms after remission. Only few reports regarding immune-mediated polyneuropathy induced by malignant lymphoma are available in the literature, which, together with this case, suggest that prompt control of malignant lymphoma is crucial for favorable prognosis of neuropathy.

Abstract
Blastic plasmacytoid dendritic cell (pDC) neoplasm (BPDCN) is a relatively rare hematological malignancy with significantly complex clinicopathological features that are still unclear. This study aimed to analyze the clinicopathological data of BPDCN and evaluate immunohistochemical detection of minimal bone marrow (BM) involvement. In this study, we examined skin and BM lesions from 6 patients with BPDCN. Neoplastic cells tested positive for CD303 (polyclonal, 100%; monoclonal, 40%) in the skin lesions and for CD303 (polyclonal, 100%; monoclonal, 67%) in the BM clots. Although immunostaining of CD4, CD56, CD123, CD303, and TCLl detected minimal BM involvement in 3 patients, morphological identification was challenging in the BM clots stained with hematoxylin-eosin. In conclusion, our results demonstrate the significance of observing BM smears to detect neoplastic cells and that immunohistochemical examination, including CD303 antibodies, is useful to detect minimal BM involvement. This study is the first to report the expression of thymic stromal lymphopoietin (TSLP) and its receptor in BPDCN cells. Therefore, the TSLP/TSLP receptor axis may be associated with the proliferation of BPDCN, and consequently, the survival of patients.

Abstract
BACKGROUND In comparison with foreign countries, living-organ transplantations (LOT) have been performed more frequently than dead organ transplants, including brain-dead organ transplantation (BOT) in Japan. This situation has given rise to organ transplantation tourism. Therefore, we clarify laypersons' preferences regarding organ transplantation that are producing the current situation in Japan, to suggest a possible framework for further efforts. METHODS Voluntary completion of a quantitative and anonymous survey was promoted online (a sample size of 1030). The questionnaire had two types of variables concerning demographic characteristics and organ transplantation-related issues. RESULTS LOT was favored over BOT. However, for willingness to donate to family members, the participants showed a significantly more positive attitude toward brain-dead organ donors (BODs) than living organ donors (LODs). In the evaluation of each transplantation technology, BOT and LOT were positioned in the middle, between transplantation that does not depend on others and the utilization of animal organs. CONCLUSIONS Although LOT was favored over BOT, for participants hypothesized to be in a position to donate and receive organs, BODs received a conversely better reputation than LODs. Our survey and discussion suggest that the present conditions of organ transplantation in Japan might be because there is a lack of deliberation on transplantation tourism and LOT. Therefore, more surveys concerning LOT cases and the implications of avoidance of organs from brain-dead bodies, coupled with more discussions based on these surveys, are necessary to formulate a Japanese transplantation policy for the future.

Abstract
BACKGROUND Good glycaemic control in type 2 diabetes (T2DM) protects the microcirculation. Current guidelines suggest glycaemic targets be relaxed in advanced diabetes. We explored whether disease duration or pre-existing macrovascular complications attenuated the association between hyperglycaemia and microvascular function. METHODS 743 participants with T2DM (n = 222), cardiovascular disease (CVD = 183), both (n = 177) or neither (controls = 161) from two centres in the UK, underwent standard clinical measures and endothelial dependent (ACh) and independent (SNP) microvascular function assessment using laser Doppler imaging. RESULTS People with T2DM and CVD had attenuated ACh and SNP responses compared to controls. This was additive in those with both (ANOVA p < 0.001). In regression models, cardiovascular risk factors accounted for attenuated ACh and SNP responses in CVD, whereas HbA1c accounted for the effects of T2DM. HbA1c was associated with ACh and SNP response after adjustment for cardiovascular risk factors (adjusted standardised beta (β) -0.096, p = <0.008 and -0.135, p < 0.001, respectively). Pre-existing CVD did not modify this association (β -0.099; p = 0.006 and -0.138; p < 0.001, respectively). Duration of diabetes accounted for the association between HbA1c and ACh (β -0.043; p = 0.3), but not between HbA1c and SNP (β -0.105; p = 0.02). CONCLUSIONS In those with T2DM and CVD, good glycaemic control is still associated with better microvascular function, whereas in those with prolonged disease this association is lost. This suggests duration of diabetes may be a better surrogate for "advanced disease" than concomitant CVD, although this requires prospective validation.

Abstract
The prognosis for myelodysplastic syndrome with bone marrow fibrosis (MDS-F) is worse than the prognosis of MDS without fibrosis. Hematopoietic stem cell transplantation (HSCT) is the only curative therapy; however, the indications and the procedures involved in HSCT remain unclear. We herein describe a 69-year-old Japanese man with MDS-F who received haploidentical HSCT and post-transplantation cyclophosphamide. Although the first HSCT resulted in secondary graft failure, the second HSCT using PTCy led to successful engraftment after early improvement in fibrosis. Since the incidence of graft failure is high in myelofibrosis patients, a secondary HSCT using PTCy may be successful if employed.

Abstract
BACKGROUND There is a need to develop and validate surrogate markers of cardiovascular disease (CVD) in subjects with diabetes. The macrovascular changes associated with diabetes include aggravated atherosclerosis, increased arterial stiffness and endothelial dysfunction. The aim of this study was to determine which of these factors is most strongly associated with clinically manifest cardiovascular events. METHODS Vascular changes were measured in a cohort of 458 subjects with type 2 diabetes (T2D) and CVD (myocardial infarction, stroke or lower extremity arterial disease), 527 subjects with T2D but without clinically manifest CVD and 515 subjects without T2D and with or without CVD. RESULTS Carotid intima-media thickness (IMT) and ankle-brachial pressure index were independently associated with the presence of CVD in subjects with T2D, whereas pulse wave velocity and endothelial function provided limited independent additive information. Measurement of IMT in the carotid bulb provided better discrimination of the presence of CVD in subjects with T2D than measurement of IMT in the common carotid artery. The factors most significantly associated with increased carotid IMT in T2D were age, disease duration, systolic blood pressure, impaired renal function and increased arterial stiffness, whereas there were no or weak independent associations with metabolic factors and endothelial dysfunction. CONCLUSIONS Measures of atherosclerotic burden are associated with clinically manifest CVD in subjects with T2D. In addition, vascular changes that are not directly related to known metabolic risk factors are important in the development of both atherosclerosis and CVD in T2D. A better understanding of the mechanisms involved is crucial for enabling better identification of CVD risk in T2D.

Abstract
The aim of the present study was to determine whether dehydroepiandrosterone (DHEA) administration affects bone mass and local sex hormone levels in the cancellous region of young female rats. Eleven female rats (6 weeks old) were randomly divided into 2 groups: control rats (CON, n=5) and rats treated with DHEA (DHEA, n=6). DHEA dissolved in sesame oil was administered to the DHEA group intraperitoneally at 20 mg DHEA/kg body weight, and the CON group was treated with vehicle only (sesame oil, 0.5 ml). The rats were treated with DHEA or vehicle for 3 consecutive days, followed by 1 day of no treatment. The experimental period was 8 weeks. According to dual-energy X-ray absorptiometry and high-resolution microcomputed tomography data, the DHEA group exhibited increased trabecular bone mineral density (BMD), bone volume, and tibial thickness compared to the findings in the CON group, whereas no effect was observed on cortical BMD or morphometry. The concentrations of free testosterone and estradiol in the cancellous region of the tibia did not differ between the 2 groups, but the DHT concentration was significantly higher in the DHEA group than in the CON group. These findings suggest that an increase in local DHT levels may stimulate an increase in trabecular bone mass during growth phases in female rats.

Abstract
OBJECTIVES Hyperforin, a phloroglucinol derivative of St. John's Wort, has been identified as the major molecule responsible for this plant's products anti-depressant effects. It can be expected that exposure to St. John's Wort during pregnancy occurs with some frequency although embryotoxic or teratogenic effects of St. John's Wort and hyperforin have not yet been experimentally examined in detail. In this study, to determine any embryotoxic effects of hyperforin, we have attempted to determine whether hyperforin affects growth and survival processes of employing mouse embryonic stem (mES) cells (representing embryonic tissue) and fibroblasts (representing adult tissues). MATERIALS AND METHODS We used a modified embryonic stem cell test, which has been validated as an in vitro developmental toxicity protocol, mES cells, to assess embryotoxic potential of chemicals under investigation. RESULTS We have identified that high concentrations of hyperforin inhibited mouse ES cell population growth and induced apoptosis in fibroblasts. Under our cell culture conditions, ES cells mainly differentiated into cardiomyocytes, although various other cell types were also produced. In this condition, hyperforin affected ES cell differentiation into cardiomyocytes in a dose-dependent manner. Analysis of tissue-specific marker expression also revealed that hyperforin at high concentrations partially inhibited ES cell differentiation into mesodermal and endodermal lineages. CONCLUSIONS Hyperforin is currently used in the clinic as a safe and effective antidepressant. Our data indicate that at typical dosages it has only a low risk of embryotoxicity; ingestion of large amounts of hyperforin by pregnant women, however, may pose embryotoxic and teratogenic risks.

Abstract
The dissolution and degradation of dagger-endotoxin (crystal) of Bacillus thuringiensis subsp. kurstaki strain HD-1 were investigated. Crystals were dissolved in 0.1 M phosphate-carbonate-NaOH buffer at pH > 12. Swelling of crystals occurred in the buffer between pH 10 and 11, and crystals dissolved in the same buffer supplemented with gut juice protease of the silkworm Bombyx mori. The proteolytic dissolution of crystals occurred after a time lag of several minutes in 0.1 M carbonate-NaOH buffer, pH 10.2. The time lag was not observed when crystals were suspended in the buffer for 30 min before the addition of protease. After the dissolution of the crystals and further degradation of the solubilized protein, the appearance of a toxic protein with a molecular weight of 59,000, designated P-59, was observed. Lower-molecular-weight peptides (less than 40,000) showed no toxicity to the silkworm larvae on feeding. Digestion of the 120,000-dalton subunit of the crystal by gut juice protease also produced P-59. These observations suggest the occurrence of a similar process in vivo, i.e., the swelling of crystals due to the alkalinity of gut juice and the production of P-59, dependent on the hydrolysis of swollen crystals by gut juice protease.

Abstract
A compact cubic-anvil high-pressure device was developed for in situ neutron powder diffraction studies. In this device, a cubic shaped pressure medium is compressed by six anvils, and neutron beams pass through gaps between the anvils. The first high-pressure experiment using this device was conducted at J-PARC and clearly showed the neutron diffraction patterns of Pb. Combining the cubic-anvil high-pressure device with a pulsed neutron source will prove to be a useful tool for neutron diffraction experiments.

Abstract
AIM Addition of dehydroepiandrosterone (DHEA) to a cultured skeletal muscle locally synthesizes 5alpha-dihydrotestosterone (DHT). It induced activation of glucose metabolism-related signalling pathway via protein kinase B (Akt) and protein kinase C zeta/lambda (PKC zeta/lambda)-glucose transporter-4 (GLUT4) proteins. However, such an effect of DHEA in vivo remains unclear. METHODS Using streptozotocin (STZ)-induced rats with type 1 diabetes mellitus, we tested the hypothesis that a single bout of DHEA injection in the rats improves hyperglycaemia and muscle GLUT4-regulated signalling pathway. After 1 week of STZ injection (55 mg kg(-1)) with male Wistar rats, fasting glucose concentrations were determined in a blood sample taken from the tail vein. Blood glucose levels were then monitored for 180 min after DHEA or sesame oil (control) was injected (n = 10 for each group). RESULTS Blood glucose levels decreased significantly for 30-150 min after 2 mg DHEA injection in the STZ rats. In the skeletal muscle, expression and translocation of GLUT4 protein, phosphorylation of Akt and PKC zeta/lambda, and phosphofructokinase and hexokinase enzyme activities increased significantly by DHEA injection. However, DHEA-induced improvements in Akt and PKC zeta/lambda-GLUT4 pathways were blocked by a DHT inhibitor. CONCLUSION These results suggest that a single bout of DHEA injection can improve hyperglycaemia and activate the glucose metabolism-related signalling pathway via Akt and PKC zeta/lambda-GLUT4 proteins of skeletal muscles in rats. Moreover, these results show that a DHEA-induced increase in muscle glucose uptake and utilization might contribute to improvement in hyperglycaemia in type 1 diabetes mellitus.

Abstract
AIM The authors hypothesized that inconsistent SIgA response to exercise is caused by the different adaptative status of subjects to a cold environment. The purposes of the study were to examine whether moderate-intense exercise in a cold environment decreases SIgA and whether adaptation to a cold environment has any effect on SIgA. METHODS Young male skaters, short track (N=9) and inline (N=10), participated in this study. All subjects cycled for 60 min at 65% VO(2max) in cold (ambient temperature: 5 +or - 1 degrees Celsius, relative humidity 41 + or - 9%) and thermoneutral (ambient temperature: 21 + or - 1 degrees Celsius, relative humidity 35 + or - 5%) conditions. Saliva samples were collected as follows: before and after 1hour of environmental exposure; immediately, 30-min, 60-min and 120-min after the exercise. RESULTS AND CONCLUSIONS Salivary SIgA and saliva flow rate decreased after the exercise in both groups only in thermoneutral conditions. The SIgA secretion rate did not decrease after moderate-high intensity exercise in a cold environment, and the SIgA response to exercise was not affected by the different adaptative status of subjects to the cold environment.

Abstract
Radiation-induced bystander effects are established consequences of exposure to ionizing radiation. The operation of this mechanism has been seen in vitro and also between fish, mammals, and plants in vive where stress signals from treated organisms induce responses in neighbors. In vitro research shows that DNA repair deficient cells produce more toxic bystander responses. To test this in vivo two strains of Japanese medaka were tested. One is a mutant, repair deficient strain (ric2) and the other, the wildtype repair proficient strain (CAB). Irradiated fish swam with unirradiated partners in a strain mix and match protocol. The data suggest that medaka produce signals, when exposed to radiation, that induce unirradiated fish ofthe same strain swimming with them to produce an altered response to that seen in bystanders to sham irradiated fish. More apoptosis was seen in bystanders to repair deficient fish. When the strains are mixed, the bystanders of either strain respond like the donor strain. Measurements of Bcl-2 and cmyc proteins in the explants confirmed these observations. A possible role for p53 was also identified in that the use of reporters with mutant p53 demonstrated that CAB signals killed all the reporter cells by apoptosis. Use of a similar but p53 wildtype cell line had no such effect. The data add to the body of knowledge showing that bystander signals operate at hierarchical levels of organization greater than the individual and may therefore have relevance in radioecology and (eco)systems biology.

Abstract
We aimed to develop a valid model of immunosuppression induced by intense exercise in rats. Rats were divided into three groups. In the rest (Rest) group, saliva was collected from resting rats on 4 consecutive days. In the exercise (Ex) group, rats ran on a treadmill until exhaustion (exercise time: 60.0 +/- 3.7 min), and their saliva was collected before and after exercise; the salivary glands were removed after exercise. In the control (Con) group, saliva collection and gland removal were also performed, but the rats did not exercise. Secretory immunoglobulin A (SIgA) concentrations in saliva and polymeric immunoglobulin receptor (pIgR) mRNA expression in the glands were measured. There was no significant change in SIgA concentration in the Rest group over 4 days. In the Ex group, SIgA concentration decreased significantly after exercise compared with before, whereas there was no significant change in the Con group. The expression of pIgR mRNA was significantly lower in the Ex group post-exercise than in the Con group. Our procedure for saliva collection appeared suitable, and the exercise-induced SIgA suppression was probably caused by a decline in pIgR mRNA expression. We propose to use this reproducible and reliable rat model of exercise-induced SIgA suppression in future studies.

Abstract
This study reports on a 57-year-old woman who underwent a 3rd mitral valve replacement and presented with complaints of fatigue. Laboratory examination revealed severe hemolytic anemia, and trans-esophageal echocardiography revealed a paravalvular leak (PVL) around the prosthetic valve at the posterior trigone in the mitral position. PVL was regarded as the cause of hemolytic anemia. At surgery, a small tissue defect was detected around the calcified posterior trigone of the mitral annulus with no evidence of infective endocarditis. The mitral PVL was successfully repaired with suture closure of the annular defect. The postoperative course was uneventful: postoperative echocardiography revealed no evidence of PVL, and the hemolytic anemia subsided.

Abstract
A 60-year-old woman had previously undergone aortic valve replacement for aortic regurgitation. As the aortic wall was elastic hard, inflammatory change was suspected; therefore, we undertook a partial biopsy of the ascending aortic wall and the intraoperative pathological specimens were compatible with aortitis syndrome. As there was no active inflammatory change, she was diagnosed as inactive aortitis syndrome and steroid therapy was not applied. Seven years later, a follow-up computed tomography (CT) showed an ascending aortic aneurysm of 65 mm in diameter. Aortic root replacement was planned based on a clinical diagnosis of an aneurysm of the ascending aorta. The patient was discharged without complication 21 days after surgery. It is possible that an inactive stage of aortitis may lead to late dilatation of the ascending aorta; therefore, careful postoperative follow-up is necessary in such cases.

Abstract
AIM This study was intended to investigate various hormones during competition among female athletes. METHODS Subjects were elite female soccer players (n=9). Blood samples and profiles of mood states (POMS) were obtained before (Pre), during 3 days of competition (Competition), and after competition (Post-3 days). Serum concentrations were determined for dehydroepiandrosterone sulfate (DHEAS), cortisol (C), prolactin (PRL), testosterone (T), adrenocorticotropic hormone (ACTH), luteinising hormone (LH), and follicle stimulating hormone (FSH). RESULTS Levels of C and PRL increased significantly during competition (2nd: P<0.05; 3rd: P<0.01) compared with Pre. Levels of LH increased significantly during competition (3rd day) compared with Pre (P<0.05). Levels of DHEAS changed significantly during competition, whereas levels of T, ACTH, and FSH were unchanged during competition. The fatigue score of POMS increased significantly during competition (2nd day) compared with Pre (P<0.05). CONCLUSIONS We demonstrated that competitive stress affected hormonal status in female athletes. These findings suggest that hormonal changes reflect physical and mental stress during competition.
