Abstract
We investigated the molecular basis of factor VII (FVII) deficiency in a Japanese patient and identified compound heterozygous mutations. Factor VII activity and antigen levels in the patient were less than 5.0% and 6.5% of controls, respectively. All exons, exon-intron boundaries, and the 5' promoter region of F7 from genomic DNA were amplified using polymerase chain reaction (PCR). Sequencing analysis of PCR fragments revealed that the patient was heterozygous for a known T to C substitution at nucleotide position 38, which resulted in the p.Leu13Pro missense mutation (Factor VII Morioka) in the signal peptide region, and a novel mutation in the 5' promoter region (-58G>C). An electrophoretic mobility shift assay showed that the mutation in the promoter region reduced the binding of hepatocyte nuclear factor (HNF). It is presumed that the reduced binding of HNF-4 to the F7 promoter region reduces F7 transcription and thus reduces the synthesis and expression of FVII.

Abstract
Abstract
Background
Coronary microvascular dysfunction (CMD) is an early feature of diabetic cardiomyopathy, which usually precedes the onset of systolic and diastolic dysfunction (DDF). Continuous intracoronary thermodilution allows an accurate and reproducible assessment of absolute coronary blood flow and microvascular resistance thus allowing the evaluation of coronary flow reserve (CFR) and Microvascular Resistance Reserve (MRR), a novel index specific for microvascular function, which is independent from the myocardial mass. In the present study we compared absolute coronary flow and resistance, CFR and MRR assessed by continuous intracoronary thermodilution in diabetic versus non-diabetic patients. Left atrial reservoir strain (LASr), an early marker of DDF was compared between the two groups.
Methods
In this observational retrospective study, 108 patients with suspected angina and non-obstructive coronary artery disease (NOCAD) consecutively undergoing elective coronary angiography (CAG) from September 2018 to June 2021 were enrolled. The invasive functional assessment of microvascular function was performed in the left anterior descending artery (LAD) with intracoronary continuous thermodilution. Patients were classified according to the presence of DM. Absolute resting and hyperemic coronary flow (in mL/min) and resistance (in WU) were compared between the two cohorts. FFR was measured to assess coronary epicardial lesions, while CFR and MRR were calculated to assess microvascular function. LAS, assessed by speckle tracking echocardiography, was used to detect early myocardial structural changes potentially associated with microvascular dysfunction.
Results
The median FFR value was 0.83 [0.79–0.87] without any significant difference between the two groups. Absolute resting and hyperemic flow in the left anterior descending coronary were similar between diabetic and non-diabetic patients. Similarly, resting and hyperemic resistances did not change significantly between the two groups. In the DM cohort the CFR and MRR were significantly lower compared to the control group (CFR=2.4±0.6 and 2.9±0.8; MRR=2.8±0.9 and 3.5±1 for diabetic and non-diabetic patients respectively, [p<0.05 for both], Figure 1 and 2). Likewise, diabetic patients had a significantly lower reservoir, contractile and conductive LAS (all p<0.05).
Conclusions
Compared with non-diabetic patients, CFR and MRR were lower in patients with DM and non-obstructive epicardial coronary arteries, while both resting and hyperemic coronary flow and resistance were similar. LASr was lower in diabetic patients, confirming the presence of a subclinical DDF associated to the microcirculatory impairment. Continuous intracoronary thermodilution-derived indexes provide a reliable and operator-independent assessment of coronary macro- and microvasculature and might potentially facilitate widespread clinical adoption of invasive physiologic assessment of suspected microvascular disease.

Abstract
We assess the magnetic field configuration in modern fusion devices by comparing experiments with the same heating power, between a stellarator and a heliotron. The key role of turbulence is evident in the optimized stellarator, while neoclassical processes largely determine the transport in the heliotron device. Gyrokinetic simulations elucidate the underlying mechanisms promoting stronger ion scale turbulence in the stellarator. Similar plasma performances in these experiments suggests that neoclassical and turbulent transport should both be optimized in next step reactor designs.

Abstract
The analysis method of the Motional Stark Effect (MSE) diagnostic to measure the rotational transform and current profiles in the Large Helical Device has been improved. This was done by using the Variational Moments Equilibrium Code to calculate an equilibrium database for various pressure profiles and current profiles. This method looks for the radial profile of the rotational transform in the equilibrium database that gives the best fit to the polarization angle profiles measured with the MSE diagnostic. This analysis improves the measurements of rotational transform, especially near the magnetic axis, where the sensitivity of the polarization angle measurements becomes low and the uncertainty due to error in the estimation of the Pfirsch-Schlüter current becomes large. The radial profiles of the rotational transform and current profiles for Electron Cyclotron Current Drive and Neutral Beam Current Drive are obtained in the new analysis method with a sufficiently high accuracy to discuss the discrepancy of the current density profiles between the measurements and the calculations.

Abstract
Multicentric Castleman disease (MCD) comprises a heterogeneous group of lymphoproliferative disorders. Interleukin 6 (IL-6) plays an important role in the MCD pathophysiology. Here, we report the case of a 17-year-old Japanese man who presented with fever, headache, fatigue, and weight loss, with normal blood pressure. A movable mass was palpated in his lower abdomen. Laboratory tests revealed microcytic anemia and hypoalbuminemia, with elevated IL-6, sIL-2R, and vascular endothelial growth factor. Computed tomography of the abdomen demonstrated a 55-mm-diameter pelvic tumor and enlarged mesenteric lymph nodes. MCD was suspected, and the pelvic tumor resected. After the operation, his blood pressure rose slowly, and resulted to seizures of posterior reversible encephalopathy syndrome. Evaluation of hypertension revealed that plasma norepinephrine and normetanephrine concentrations were elevated, and pathological examinations showed that the resected tumor was positive for IL-6 and chromogranin-A. Therefore, we diagnosed the patient with IL-6-producing paraganglioma with MCD-mimicking symptoms. Moreover, IL-6-producing pheochromocytoma and paraganglioma should be included in differential diagnoses of MCD, even in normotensive patients.

Abstract
Dose-adjusted (DA)-EPOCH-R causes profound neutropenia requiring relatively long hospital stays with multiple doses of granulocyte colony-stimulating factor (G-CSF). A single-dose pegylated G-CSF (PEG-G-CSF) has been used for the treatment of chemotherapy-induced neutropenia. We retrospectively examined 15 patients (median age 61, range 33-75 years) treated with DA-EPOCH-R. In the first cycle of the DA-EPOCH-R therapy, a G-CSF preparation was used, and since the second cycle, the G-CSF and PEG-G-CSF use groups were divided. The median length of hospitalization after starting chemotherapy in the second-cycle DA-EPOCH-R was significantly shorter with PEG-G-CSF group (n=9) of 9 (7-13) days compared with G-CSF group (n=6) of 18 (15-22) days (P<0.001). Risk factors of febrile neutropenia, such as bone marrow invasion, performance status, serum albumin, and history of febrile neutropenia at the first DA-EPOCH-R cycle or previous chemotherapy were not significantly different for both groups, and the incidence of febrile neutropenia in PEG-G-CSF and G-CSF groups was 2.6% and 46.9%, respectively. These analyses suggest that PEG-G-CSF can be combined with DA-EPOCH-R without compromising treatment outcomes as compared with the daily dose of G-CSF.

Abstract
Challenges with various TLR ligands (TLRLs)in combination with D-galactosamine (GalN) in rodents may mimic diverse conditions of acute inflammation and organ failure. Here, we report that CpG (ODN1826, TLR9 agonist)/GalN induced a liver-specific injury with modest systemic effects, whereas R848 (resiquimod, TLR7/8 agonist)/GalN exhibited systemic and liver toxicity. We also observed the protective effect of Gr-1+ cells (the population containing neutrophils) against liver injury in both the R848/GalN and CpG/GalN models. In cytokine measurements, the intraperitoneal administration of antibodies showed a non-specific tolerance induction effect, which was more pronounced in the CpG/GalN than in the R848/GalN model. Cytokine analyses also suggested that the TLR9 agonist/GalN induced a limited degree of systemic inflammation compared to TLR7/8 agonist/GalN models. The relevance of this finding to the TLR9-mediated induction of stress tolerance (protective effect) in non-immune cells is discussed.

Abstract
A diamond-based neutral particle analyzer (DNPA) array composed of single-crystal chemical vapor deposition (sCVD) diamond detectors was installed on the Large Helical Device (LHD) for measuring the helically trapped energetic particles. In high neutron flux experiments, the unwanted neutron-induced pulse counting rate should be estimated using the neutron diagnostics because a diamond detector is sensitive to neutrons as well as energetic neutral particles. In order to evaluate the quantitative neutron-induced pulse counting rate on the DNPA, the response functions of the sCVD diamond detector for mono-energetic neutrons were obtained using accelerator-based D-D and D-7Li neutron sources in Fast Neutron Laboratory (FNL). As a result of the neutron flux estimation by the Monte Carlo N-Particle code at the NPA position in the LHD and the response function obtained in the FNL experiment, the counting rate of the neutron-induced signal was predicted to be 1.1 kcps for the source neutron emission rate of Sn = 1 × 1015 n/s. In the LHD experiment, the neutron-induced signals were observed by closing the gate valve during the plasma discharges. It is found that the counting rates of the neutron-induced signals proportional to Sn reached 1.1 kcps at Sn = 1 × 1015 n/s. As a result of the quantitative estimation of the neutron-induced signals on the DNPA using other neutron measurements, it has become possible to accurately measure energetic neutral particles in the high neutron flux experiment.

Abstract
BCR-ABL1-like acute lymphoblastic leukemia (ALL) is a neoplasm of lymphoblasts committed to the B-cell lineage that lack the BCR-ABL1 translocation but show a pattern of gene expression very similar to that seen in ALL with BCR-ABL1 with poor prognosis. A 22-year-old female was diagnosed with common-B-cell-ALL positive for CD10, CD19, CD22, CD79a, CD34, HLA-DR, and TdT in January 2017, and achieved complete remission (CR) with induction therapy, followed by consolidation therapy and maintenance therapy. In March 2020, 6 months after the completion of maintenance therapy, she relapsed. Inotuzumab ozogamicin (IO) was administered, and on day 28, bone marrow evaluation showed a morphologic CR. She had an HLA-identical sibling, and transplantation in her 2nd CR was planned. Because her ALL had been identified as BCR-ABL1-like ALL with CCDC88C-PDGFRB fusion, she was treated with imatinib for 2 months accompanied by 2 intrathecal methotrexate therapies, and 1 course of L-asparaginase, vincristine, and prednisolone in an outpatient setting. MRD analysis revealed potent efficacy of 2 months imatinib therapy; IgH MRD decreased from 1 × 10-2 to 1 × 10-3, and CCDC88C-PDGFRB/104ABL from 37.3 to 0. It is earnestly desired that well-designed clinical trials of TKI in ABL class-mutant BCR-ABL1-like ALL be conducted in Japan.

Abstract
Two new vertical neutron cameras characterized by high detection efficiency were developed on the Large Helical Device in order to observe poloidal structures of helically trapped beam ions created by the perpendicularly injected positive-ion based neutral beam (P-NB) and are newly operated since 2018. In this work, the neutron fields at the vertical neutron cameras are investigated using the Monte Carlo N-particle transport code to evaluate the performance of its collimators. The results indicate that neutrons are attenuated by the heavy concrete and are well collimated through the collimator to detectors. Neutron spectra at the detector position show over 99% of uncollided 2.45 MeV neutrons. Time evolution of neutron emission profiles during the short pulse of P-NB injection is measured by the vertical neutron cameras. Peaks on the neutron emission profiles corresponding to the helically trapped beam ion are successfully obtained, as designed. The decrease in line integrated neutron flux at the peak positions after the P-NB stops is consistent with the behavior of the total neutron emission rate measured by the neutron flux monitor.

Abstract
BACKGROUND Factor V (FV) deficiency is a monogenic inherited coagulation disorder considered to be an ideal indication for gene therapy. To investigate the possibility of therapeutic application of genome editing, we generated induced pluripotent stem cells (iPSCs) from a FV-deficient patient and repaired the mutation of factor V gene (F5) using a clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9). METHODS The patient's peripheral blood mononuclear cells were reprogrammed for iPSCs. The targeting vector was designed with homology arms against F5 containing the corrected sequence. Cas9 ribonucleoprotein (RNP) complex and targeting vector were electroporated into iPSCs. Gene-edited iPSCs were differentiated into hepatocyte-like cells (HLCs). RESULTS The mutation of F5 in patient-derived iPSCs was repaired by CRISPR/Cas9. In concentrated culture supernatants of patient-derived iPS-HLCs, neither FV antigen nor activity was detected, while in those of gene-corrected iPS-HLCs, FV antigen and specific activity were 67.0 ± 13.1 ng/mL and 173.2 ± 41.1 U/mg, respectively. CONCLUSIONS We successfully repaired the mutation of F5 using the CRISPR/Cas9 and confirmed the recovery of FV activity with gene-corrected iPS-HLCs. Gene-edited iPSCs are promising for elucidating the pathophysiology as well as for a modality of gene therapy.

Abstract
The isotope effect on energy confinement time and thermal transport has been investigated for plasmas confined by a stellarator-heliotron magnetic field. This is the first detailed assessment of an isotope effect in a stellarator heliotron. Hydrogen and deuterium plasmas heated by neutral beam injection on the Large Helical Device have exhibited no significant dependence on the isotope mass in thermal energy confinement time, which is not consistent with the simple gyro-Bohm model. A comparison of thermal diffusivity for dimensionally similar hydrogen and deuterium plasmas in terms of the gyroradius, collisionality, and thermal pressure has clearly shown robust confinement improvement in deuterium to compensate for the unfavorable mass dependence predicted by the gyro-Bohm model.

Abstract
The clustered regulatory interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) system is an efficient genome-editing tool that holds potential for gene therapy. Here, we report an application of this system for gene repair in hemophilia B (HB) using induced pluripotent stem cells (iPSCs). We prepared targeting plasmids with homology arms containing corrected sequences to repair an in-frame deletion in exon 2 of the factor IX (F9) gene and transfected patient-derived iPSCs with the Cas9 nuclease and a guide RNA expression vector. To validate the expression of corrected F9, we attempted to induce the differentiation of iPSCs toward hepatocyte-like cells (HLCs) in vitro. We successfully repaired a disease-causing mutation in HB in patient-derived iPSCs. The transcription product of corrected F9 was confirmed in HLCs differentiated from gene-corrected iPSCs. Although further research should be undertaken to obtain completely functional hepatocytes with secretion of coagulation factor IX, our study provides a proof-of-principle for HB gene therapy using the CRISPR/Cas9 system.

Abstract
Sonic hedgehog ( Shh) is important in pattern formation during development. Shh transcription is modulated by a long-range regulatory mechanism containing a number of enhancers, which are spread over nearly 850 kb in the mouse genome. Shh enhancers in the nervous system have been found between intron and 430 kb upstream of Shh. Enhancers in the oral cavity, pharynx, lung, gut, and limbs have been discovered between 610 kb and 850 kb upstream of Shh. However, the intergenic region ranging from 430 to 610 kb upstream of Shh remains to be elucidated. In the present study, we found a novel long-range enhancer located 558 kb upstream of Shh. The enhancer showed in vivo activity in oral cavity and whiskers. A targeted deletion from the novel enhancer to mammal reptile conserved sequence 1 (MRCS1), which is a known enhancer of Shh in oral cavity, resulted in supernumerary molar formation, confirming the essential role of this intergenic region for Shh transcription in teeth. Furthermore, we clarified the binding of Lef1/Tcfs to the new enhancer and MRCS1, suggesting that Wnt/β-catenin signaling regulates Shh signaling in the oral cavity via these enhancers.

Abstract
The resistive interchange mode destabilized by the resonant interaction with the trapped energetic ions is fully suppressed when the injected power of electron cyclotron heating exceeds a certain threshold. It is shown for the first time that the complete stabilization of the energetic-particle-driven mode without relaxing the energetic particle (EP) pressure gradient is possible by reducing the radial width of the eigenmodes δ_{w}, especially when δ_{w} narrows to a small enough value relative to the finite orbit width of EP.

Abstract
A 10-day-old male patient was referred to our hospital with severe umbilical bleeding. Prothrombin time (PT) and activated partial thromboplastin time (APTT) were prominently prolonged. Plasma coagulation factor X (FX) activity and antigen levels were 1% and 0.6%, respectively. A DNA sequence analysis of his leukocytes revealed a compound heterozygous state; known Gly244 to Arg (p.G244R) in exon 6 and a novel mutation of Gly 435 to Ser (p.G435S) in exon 8. A pedigree analysis showed that p.G244R originated from the paternal side, while p.G435S was from the maternal side. A p.G244R mutation was reported previously as FXDebrecen and this mutated protein was synthesized as a non-secretable protein. The glycine at amino acid position 435 in the C-terminal region is completely conserved in the trypsin-like serine protease family, including thrombin, FVII, protein C, plasmin, trypsin, and chymotrypsin. In a three-dimensional structural model of FX, Gly 435 was located within the 11th β-strand and buried in the back of the catalytic pocket. Therefore, the substitution to serine was expected to disrupt this structure. p.G435S FX was also predicted to be synthesized and exist in the cytoplasm, but not to be secreted into culture media by a cDNA expression assay. These two mutations may be responsible for the type 1 (null levels of both activity and antigen in plasma) FX deficiency with severe bleeding phenotype.

Abstract
A 72-year-old Japanese male was diagnosed as having monoclonal gammopathy of undetermined significance and was followed up without therapy. Three years later, the patient progressed to symptomatic multiple myeloma. Melphalan + prednisolone was administered as first-line chemotherapy for ~6 years. Since the patient was judged to exhibit refractory multiple myeloma, he subsequently received radiation therapy on the lumbar spine. The patient was enrolled in a clinical trial and received lenalidomide + lowdose dexamethasone (Rd) therapy. The patient achieved very good partial remission following four cycles of Rd. At this time, large granular lymphocytes (LGLs) increased to 25-40% of peripheral blood leukocytes, however, the LGLs were present in the blood (~8%) prior to lenalidomide treatment. By flow cytometry of surface antigens, it was revealed that the LGLs were positive for cluster of differnetiation (CD)2, 7, 8, 16, 56, and 57, and human leukocyte antigen-D related, however, were negative for CD3, 4 and 5, suggesting that these LGLs predominantly exhibited an natural killer (NK) cell phenotype. T-cell receptor β gene rearrangement was not detected by polymerase chain reaction. A 51Cr release assay was performed to investigate whether the NK cells actually possessed activity. A low level of M protein was sustained for ~15 months. This implied the enhancement of immune activation during lenalidomide treatment. The present case study suggested that LGL cells induced by lenalidomide may contribute to long-term restraint of myeloma cells. This immune system component may contribute to disease control.

Abstract
A new bursting m=1/n=1 instability (m,n: poloidal and toroidal mode numbers) with rapid frequency chirping down has been observed for the first time in a helical plasma with intense perpendicular neutral beam injection. This is destabilized in the plasma peripheral region by resonant interaction between helically trapped energetic ions and the resistive interchange mode. A large radial electric field is induced near the edge due to enhanced radial transport of the trapped energetic ions by the mode, and leads to clear change in toroidal plasma flow, suppression of microturbulence, and triggering an improvement of bulk plasma confinement.

Abstract
Thrombotic complications are a major cause of death in patients with Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs), which are closely associated with the JAK2 V617F activating mutation. However, whether the presence of the JAK2 V617F mutation affects thrombotic risk is currently unknown, although some reports have suggested a variable association with thrombosis. Therefore, we investigated the association between JAK2 V617F and various complications, including thrombosis, in Japanese patients with MPNs. We assessed the JAK2 V617F status in 140 patients who were diagnosed or doubted as having some type of MPN by utilizing a JAK2 V617F-specific guanine-quenching probe. JAK2 V617F was detected in 31 of 51 patients (60.8%) with essential thrombocythemia, all 16 patients (100%) with polycythemia vera, 4 of 11 patients (36.4%) with primary myelofibrosis, 2 of 18 patients (11.1%) with other types of MPNs, and none of the 44 patients with doubted MPN. In the 78 patients with classical MPN, JAK2 V617F correlated with a leukocyte count ≥10,000/μl (p=0.046). Complications of thrombosis, hemorrhage, and leukemic transformation occurred in 21 (41.2%), 4 (25.0%), and 3 (27.3%) patients with classical MPN, respectively, and thrombotic events (TE) occurred more frequently in patients with JAK2 V617F than without (p=0.047). Based on these findings, initial screening for the JAK2 mutation and careful monitoring for thrombotic events should be performed in patients with MPN.

Abstract
A 65-year-old Japanese male with therapy-related myelodysplastic syndrome was admitted for unrelated cord blood transplantation. A cord blood unit from a male donor was obtained from the Japan Cord Blood Bank Network. The patient then received a conditioning regimen consisting of fludarabine, intravenous busulfan, and total body irradiation. Successful engraftment was obtained. The bone marrow examination on day 28 revealed trilineage engraftment, and chimerism analysis by variable number of tandem repeat polymerase chain reaction confirmed complete donor chimerism. At that time, conventional cytogenetics of the bone marrow aspirate showed 20 out of 20 metaphases with the 47, XXY karyotype characteristic of Klinefelter syndrome. Klinefelter syndrome is the most common genetic cause of human male infertility with a reported prevalence of 0.1–0.2% in the general population. In Japan Cord Blood Bank Network, there is no informed consent from parents about the possibility that post-unrelated cord blood transplantation patient evaluation may reveal donor-origin inherited diseases including cytogenetic abnormality. It is desirable to have opportunities in Japan discussing whether parents will be notified of the possibility that post-unrelated cord blood transplantation evaluation may reveal donor-derived illness incidentally.

Abstract
Both cellular and humoral immune responses are crucial to induce potent anti-tumor immunity, but most of currently conducted peptide-based cancer vaccines paid attention to cellular responses alone, and none of them are yet approved as a therapeutic modality against cancer patients. We investigated humoral immune responses to CTL epitope peptides derived from tumor-associated antigens in healthy donors and patients with various diseases to facilitate better understanding of their distribution patterns and potential roles. Bead-based multiplex assay, ELISA, and Western blotting were used to measure immunoglobulins reactive to each of 31 different CTL epitope peptides. Importantly, the sums of anti-peptide IgG levels specific to 31 CTL epitope peptides were well correlated with better overall survival (OS) in patients with malignant diseases. Our results suggested that humoral immune responses to CTL epitope peptides were widely detectable in humans. Measurement of immunoglobulins specific to CTL epitope peptides may provide a new biomarker for OS of patients with malignant diseases, although it still remains to be determined whether the correlations between humoral immune responses to epitope peptides and OS are observed only for the CTL epitopes used, or also for other panels of peptides. Quantity of circulating IgG reactive to these peptides was also discussed.

Abstract
A 62-year-old woman with acute lymphoblastic leukemia in first complete remission was treated with unrelated cord blood transplantation, but exhibited primary graft failure. She then underwent HLA-haploidentical peripheral blood stem cell transplantation from her daughter. The conditioning regimen consisted of fludarabine 30 mg/m(2)/day for 6 days, intravenous busulfan 3.2 mg/kg/day for 2 days, and thymoglobulin 1 mg/kg/day for 2 days. Voriconazole was administered to prevent fungal infections. The patient achieved prompt hematopoietic recovery. Fever was observed 21 days after the second transplant, followed by sigmoid colon perforation and a liver space occupying lesion (SOL). A filamentous fungus was detected in a percutaneous biopsy of the liver SOL. In spite of changing the antifungal drug from voriconazole to liposomal amphotericin B, the patient died on day 41. The fungus was identified as Mucor indicus, a type of zygomycete. Although Mucor indicus inhabits soil, an infectious disease is extremely rare, and breakthrough infection after voriconazole prophylaxis had not been reported until now. It is mandatory to consider preventive antifungal treatment for drug-resistant fungal infectious diseases in patients after neutrophilic recovery with a strongly immunocompromised state after a HLA-haploidentical transplant.

Abstract
OBJECTIVE The neovascularization-related capacities of circulating angiogenic cells (CACs) are impaired in atherosclerotic patients, which may explain the unsatisfactory effects of therapeutic angiogenesis with atherosclerotic patient-derived CACs. Platelet-derived microparticles (PMPs) were reported to augment the re-endothelialization capacity of CACs. Accordingly, we investigated whether PMPs could augment the neovascularization-related capacities of atherosclerotic patient-derived CACs in vitro and in vivo and if so, the associated mechanisms. METHODS AND RESULTS We isolated mononuclear cells and PMPs from atherosclerotic patient-derived peripheral blood and generated PMP-pretreated CACs (PMP-CACs) by co-culture of the mononuclear cells and PMPs. Although the migration capacity of PMP-CACs was similar to that of CACs, the adhesion capacity of PMP-CACs was greater. PMPs released RANTES into the culture medium, and the receptors were similarly expressed on the surfaces of CACs and PMP-CACs. Intravenous injection of PMP-CACs to rats with hindlimb ischemia augmented neovascularization of the ischemic limbs more than the injection of CACs. The number of PMP-CACs incorporated into the capillaries of the ischemic limbs was greater than that of incorporated CACs. The augmented adhesion and neovascularization capacities by PMP-CACs were canceled out by a RANTES neutralizing antibody. CONCLUSIONS PMP-secreted RANTES may play a role in the augmenting adhesion and neovascularization capacities of CACs. Injection of PMP-CACs may be a new strategy to augment the effects of therapeutic angiogenesis for limb ischemia in atherosclerotic patients.

Abstract
Vascular endothelial growth factor (VEGF) has been reported not only to induce angiogenesis within the bone marrow, but also directly stimulate the proliferation and survival of multiple myeloma cells, thus being involved in the development and progression of this second most common hematological malignancy. We, along with others, have found that pigment epithelium-derived factor (PEDF) has anti-angiogenic and anti-vasopermeability properties both in cell culture and animal models by counteracting the biological actions of VEGF. However, effects of PEDF on VEGF-exposed myeloma cells remain unknown. In this study, we examined whether and how PEDF could inhibit the VEGF-induced proliferation and survival of myeloma cells. PEDF, a glutathione peroxidase mimetic, ebselen, or an inhibitor of NADPH oxidase, diphenylene iodonium significantly inhibited the VEGF-induced reactive oxygen species (ROS) generation, increase in anti-apoptotic and growth-promoting factor, myeloid cell leukemia 1 (Mcl-1) expression, and proliferation in U266 myeloma cells. VEGF blocked apoptosis of multiple myeloma cells isolated from patients, which was prevented by PEDF. PEDF also reduced p22phox levels in VEGF-exposed U266 cells. Furthermore, overexpression of dominant-negative human Rac-1 mutant mimicked the effects of PEDF on ROS generation and Mcl-1 expression in U266 cells. Our present study suggests that PEDF could block the VEGF-induced proliferation and survival of multiple myeloma U266 cells through its anti-oxidative properties via suppression of p22phox, one of the membrane components of NADPH oxidase. Suppression of VEGF signaling by PEDF may be a novel therapeutic target for multiple myeloma.

Abstract
The 8p11 myeloproliferative syndrome is a rare neoplasm associated with chromosomal translocations involving the fibroblast growth factor receptor 1 (FGFR1) gene located at chromosome 8p11-12. FGFR1 encodes a transmembrane receptor tyrosine kinase. The resultant fusion proteins are constitutively active tyrosine kinases that drive the proliferation of hematopoietic cells, whose uncontrolled growth can present as a myeloproliferative neoplasm. We report here the case of a 50-year-old man harboring the t(8;22)(p12;q11) chromosomal translocation in cells from both bone marrow and lymph nodes. He presented with acute leukemia and lymphoma with trilineage features. A novel mRNA in-frame fusion between exon 4 of the breakpoint cluster region (BCR) gene at chromosome 22q11 and exon 9 of FGFR1 gene on chromosome 8p11-12 was identified by reverse transcription polymerase chain reaction analysis and was confirmed by DNA sequencing. Because the patient was refractory to chemotherapy, cord blood transplantation was performed in progressive disease. It resulted in a successful outcome in which cytogenetic complete remission has been maintained for 2 years till date.

Abstract
Our objective was to evaluate the non-germinal center (GC) profile as a marker for response and survival in DLBCL and to compare the characteristics of patients with GC and non-GC DLBCL treated with rituximab-containing regimens. In this patient-level meta-analysis, retrospective data from 712 newly diagnosed DLBCL patients treated with chemoimmunotherapy from 7 centers were analyzed. GC and non-GC profiles were defined according to the Hans algorithm. Although the non-GC profile showed a trend towards worse overall survival (HR 1.24, 95% CI 0.92-1.66; p=0.15) and progression-free survival (HR 1.29, 95% CI 0.96-1.73; p=0.09), it did not retain its value in the multivariate survival analysis. Additionally, the non-GC profile was independently associated with worse complete response rates (OR 0.55, 95% CI 0.37-0.83; p<0.01) in the multivariate logistic regression analysis. Interestingly, Asian patients had higher proportion of GC DLBCL (p=0.01).

Abstract
OBJECTIVES Patients with left unilateral spatial neglect draw a human face more satisfactorily than other objects. The aim of the present study is to examine the features of face drawings by patients with neglect and to establish their meaning in the diagnosis of neglect. METHODS Sixty-four right-handed patients with a right hemisphere stroke underwent the conventional test of the Behavioural Inattention Test (BIT) and showed left unilateral spatial neglect in one or more of the subtests. From the "drawing a man or woman" subtest, 64 samples of face drawing, in which both eyes were placed, were obtained. The percentage deviation of the location of the eyes in the face outline was calculated for 46 face drawings without discontinuity of the outline or severe distortion of the construction. The percentage deviation of the location of the eyes was compared among the patients with neglect, right-hemisphere damaged patients without neglect, and healthy control subjects. RESULTS The patients with neglect placed the eyes with greater leftward deviation in the face outline compared with the other two groups. The percentage deviation of the eyes was, however, not associated with neglect severity scored with the BIT conventional test. Forty-three percent of the patients with neglect located the eyes leftward beyond the normal range obtained from the performance of the healthy subjects, while none of the patients without neglect showed such abnormal leftward deviation. CONCLUSIONS The leftward deviation of the eyes in the face drawing suggests the presence but not the severity of left unilateral spatial neglect.

Abstract
To investigate the association between hepatitis C virus (HCV) and B cell proliferation, we searched for the clonal B cells by flow cytometric analysis of the surface immunoglobulin kappa (kappa):lambda (lambda) light chain ratios of the circulating B (CD19+) cells in 240 HCV-positive patients and 150 negative controls with liver diseases. Clonal B cells with light chain restriction (kappa:lambda ratio >3:1 or <1:2) were analyzed for CD5 expression and the presence of monoclonal immunoglobulin heavy-chain (IGH) gene rearrangements and the t(14;18) chromosomal translocation. Clonal B cells were detected in 7 cases with HCV (2.9%), but was never detected in the controls (p < 0.05). Of the 7 cases, all had monoclonal IGH gene rearrangements and one had the t(14;18) chromosomal translocation. These HCV-related clonal B cells are not uniform in the intensity of CD5 expression and showed no increase in the frequencies of CD5+ population compared with non-clonal B cells. No "chronic lymphocytic leukemia-phenotype" cells were found. The loss of clonality was observed in 2 cases treated with interferon and in one case treated with splenectomy. The longitudinal study is required to determine whether these circulating clonal B cells progress to lymphoproliferative disorders in future or not.

Abstract
The predictive value of combined 123iodine-labelled 15-( p-iodophenyl)-3 R,S-methyl pentadecanoic acid imaging (123I-BMIPP) and early technetium-99m (99mTc)-tetrofosmin imaging was compared with combined 123I-BMIPP and delayed 99mTc-tetrofosmin or 123I-BMIPP and thallium-201 (201Tl) imaging for functional outcome of stunned myocardium after acute myocardial infarction (AMI) in 37 patients with AMI. All patients underwent successful percutaneous coronary intervention with/without stenting within 24 h of symptoms. Resting 201Tl, 99mTc-tetrofosmin and 123I-BMIPP imaging were performed within 10 days of hospital admission; 99mTc-tetrofosmin imaging was also performed 6 months later. Segments were mismatched when the 123I-BMIPP score was greater than the 99mTc-tetrofosmin or 201Tl scores, and were matched when all scores were the same. Left ventricular function was estimated using wall motion score. Sensitivity and regional wall motion were significantly better in mismatching 99mTc-tetrofosmin-early/123I-BMIPP segments than mismatching 201Tl/123I-BMIPP or 99mTc-tetrofosmin-delayed/123I-BMIPP segments. It is concluded that mismatching of 123I-BMIPP and early 99mTc-tetrofosmin uptake can predict improvement in wall motion of stunned myocardium better than the other two imaging combinations.

Abstract
While several trials have suggested that leukocytapheresis by filtration can benefit patients with active ulcerative colitis (UC), mechanisms underlying these benefits are largely unknown. We studied how leukocytapheresis mobilizes bone marrow cells into the peripheral circulation in patients with active UC. Leukocytapheresis transiently reduced peripheral leukocytes, followed by an overshoot increase with emergence of immature leukocytes. The numbers of colonies and CD34(+) cells were comparable between UC patients and normal controls. Shortly after leukocytapheresis, the numbers of both colonies and CD34(+) cells increased significantly in UC patients (P < 0.0001 and P = 0.0372, respectively). This was not associated with changes in the concentration of circulating cytokines or epinephrine. These results indicate that leukocytapheresis mobilizes bone marrow cells into the circulation. This cell replacement may partly explain the therapeutic benefit in UC. The functional role of the mobilized bone marrow cells in affected intestine remains to be characterized.

Abstract
In the process of developing a new dosimetry system for atomic bomb survivors in Hiroshima and Nagasaki (DS02), an intercomparison study between (152)Eu and (36)Cl measurements was proposed, to reconcile the discrepancy previously observed in the Hiroshima data between measurements and calculations of thermal neutron activation products. Nine granite samples, exposed to the atomic-bomb radiation in Hiroshima within 1,200 m of the hypocenter, as well as mixed standard solutions containing known amounts of europium and chlorine that were neutron-activated by a (252)Cf source, were used for the intercomparison. Gamma-ray spectrometry for (152)Eu was carried out with ultra low-background Ge detectors at the Ogoya Underground Laboratory, Kanazawa University, while three laboratories participated in the (36)Cl measurement using accelerator mass spectrometry (AMS): The Technical University of Munich, Germany, the Lawrence Livermore National Laboratory, USA and the University of Tsukuba, Japan. Measured values for the mixed standard solutions showed good agreement among the participant laboratories. They also agreed well with activation calculations, using the neutron fluences monitored during the (252)Cf irradiation, and the corresponding activation cross-sections taken from the JENDL-3.3 library. The measured-to-calculated ratios obtained were 1.02 for (152)Eu and 0.91-1.02 for (36)Cl, respectively. Similarly, the results of the granite intercomparison indicated good agreement with the DS02 calculation for these samples. An average measured-to-calculated ratio of 0.98 was obtained for all granite intercomparison measurements. The so-called neutron discrepancy that was previously observed and that which included increasing measured-to-calculated ratios for thermal neutron activation products for increasing distances beyond 1,000 m from the hypocenter was not seen in the results of the intercomparison study. The previously claimed discrepancy could be explained by insufficient understanding of the measured data.

Abstract
Periostin is a secreted protein that shares structural homology with the insect axon guidance protein fasciclin 1. Periostin is expressed predominantly in collagen-rich fibrous connective tissues that are subjected to constant mechanical stresses. We have shown previously that periostin is a novel component of subepithelial fibrosis in bronchial asthma. Here, we investigated the relationship between periostin and bone marrow (BM) fibrosis. Periostin was expressed in the stroma and stromal cells of BM fibrosis specimens and to a great extent its expression levels correlated closely to the grade of fibrosis, as estimated by silver staining. However, in the present study, we found no relationship between plasma periostin levels and the extent of BM fibrosis. We also demonstrated that periostin is secreted by human BM hTERT stromal cells and that its secretion is enhanced by TGF-beta, a cytokine produced by clonal proliferation of megakaryocytes and/or monocytes. These results indicate that periostin is a component of BM fibrosis and that it may play a role in the disease progression.

Abstract
We report a 66-year-old man with hepatitis C virus (HCV)-related cirrhosis and simultaneous hepatic relapse of non-Hodgkin's lymphoma (NHL) and of hepatocellular carcinoma (HCC). Although the liver is frequently involved by NHL, hepatic colocalization of NHL and HCC is rarely detected by imaging techniques. HCV has been suggested to be lymphotrophic as well as hepatotrophic, and therefore has attracted speculation about a causative role in some cases of lymphoma. The patient had a past history of cutaneous diffuse large B cell lymphoma (DLBCL) in concurrence with HCC 32 months previously. Complete remission (CR) had been maintained for both diseases until February 2004, when ultrasonography and computed tomography (CT) showed multiple liver tumors. Two of these, appearing hyperattenuating in the arterial phase of contrast-enhanced CT, were diagnosed histopathologically as HCC, and treated with radiofrequency ablation. The other tumors, hypoattenuating in the portal phase CT, were diagnosed histopathologically as DLBCL, and treated with cyclophosphamide, tetrahydropyranyl-Adriamycin, vincristine and prednisolone (THP-COP) in combination with rituximab. CR was achieved for both DLBCL and HCC. Given the previously demonstrated immune system tropism and perturbation by HCV, the virus might have contributed to the occurrence of the NHL as well as the HCC.
