Recently, balloon-occluded TACE(B-TACE) was developed in Japan. Despite the lack of a clear definition, B-TACE is generally defined as the infusion of emulsion of chemotherapeutic agents with lipiodol followed by gelatin particles under the occlusion of feeding arteries by a microballoon catheter, which leads to the dense lipiodol emulsion(LE) accumulation in HCC nodules. This phenomenon cannot be explained only by the prevention of proximal migration and leakage of embolization materials; it further involves causing local changes in the hemodynamics of the surrounding occlusion artery and targeted HCC nodules. Balloon-occluded arterial stump pressure plays an important role in the dense LE accumulation in targeted HCC nodules. Although randomized controlled trials comparing the therapeutic effect and the prognosis of B-TACE to those of the other TACE procedures, such as conventional-TACE and drug-eluting beads TACE, are still lacking, B-TACE is thought to be a promising treatment. The purpose of this review is to summarize the mechanism, therapeutic effect, indication, prognosis and complications of BTACE.展开更多

The results indicated that for the same aggregate, the rates of strength reduction due to the increases in void ratio were the same for binders with different strengths. To study the influence of aggregate size, 3 single size aggregates with nominal sizes of 5.0, 13.0 and 20.0 mm （Nos. 7, 6 and 5 according to JIS A 5001） were used to make porous concrete. The strengths of porous concrete are found to be dependent on aggregate size. The rate of strength reduction of porous concrete with small aggregate size is found to be higher than that with larger aggregate size. At the same void ratio, the strength of porous concrete with large aggregate is larger than that with small aggregate. The general equations for porous concrete are related to compressive strength and void ratio for different binder strengths and aggregate sizes.展开更多

In addition, cost-effective treatments are highly desirable when chemotherapy must be given repeatedly. The aim of this study was to evaluate the efficacy and usefulness of 5-fluorouracil (5-FU) and high-concentration cisplatin by short-term hepatic arterial infusion chemotherapy (3-day FPL) in advanced HCC patients. Methods: Thirty patients with unresectable advanced HCC were enrolled. The patients underwent hepatic arterial infusion chemotherapy via the implanted port system with 5-FU on days 1 - 3 and a fine-powder formulation of cisplatin in suspended pre-warmed lipiodol on day 2 every 4 to 10 weeks. Tumor response was assessed one month later with CT. Results: All patients had evidence of portal vein invasion (Vp2-4). Four patients achieved a complete response (CR), 8 patients achieved a partial response (PR), and 7 patients had stable disease (SD). The median progression-free survival (PFS) and overall survival (OS) were 198 days and 452 days, respectively. The OS was significantly longer in the successful disease control group (CR, PR, and SD) than in the progressive disease group (P < 0.005). Conclusions: Three-day FPL was effective and tolerable in advanced HCC patients due to its shorter time of administration than conventional FP therapy. Therefore, repetitive 3-day FPL appears useful and contributes to improving the prognosis and QOL of patients with advanced HCC. In addition, this protocol is a cost-effective treatment.展开更多

Materials and Methods: Sixty seven patients who received palliative radiotherapy between 2014 and 2015 were enrolled. Patient diseases were bone metastasis in 51 patients, lymph node metastasis in 7 patients, brain metastasis in 2 patients, local recurrence in 3 patients, and others in 4 patients. Median irradiated dose was 30 Gy in 10 fractions for palliative radiotherapy. We used the questionnaires EORTC-QLQ-C30 and EORTC-QLQ-C15-PAL to evaluate patient QOL and the Hospital Anxiety and Depression Scale to evaluate patient mental healthcare at the start and at the end of radiotherapy. Results: As compared to scores at the start of radiotherapy, at the end of radiotherapy, NRS and face scale significantly decreased. On the other hand, Eastern Cooperative Oncology Group Performance Status did not show any changes during palliative radiotherapy. In functional scales, average scores of RF2 and EF also improved. In symptom scales, average scores of FA, PA, and SL improved. In bone metastasis group, global health status/QOL, PA, and SL significantly improved. There was relationship between anxiety improvement and QOL improvement after palliative radiotherapy. Nausea and vomiting scores of EORTC-QLQ-C15-PAL were associated with the irradiated volume of palliative radiotherapy for pelvic region. Conclusion: Patient QOL of was improved by palliative radiotherapy regardless of PS. The possibility of palliative radiotherapy having a positive influence on patient psychophysiology was also suggested in younger age.展开更多

In IMRT, minimizing differences between the conditions used during planning CT and daily treatment is important to prevent adverse events in normal tissues. In the present study, we evaluated the impact of variation in bladder volume on the doses to various organs. A total of 35 patients underwent definitive radiotherapy at Saitama Medical Center. A Light Speed RT16 (GE Healthcare) was used for planning and to obtain examination CT images. Such images were acquired after 4 - 6 days of planning CT image acquisition. The IMRT plans were optimized using the planning CT data to satisfy the dose constraints set by our in-house protocols for the PTV and the OARs. The dose distributions were then re-calculated using the same IMRT beams, and checked on examination CT images. It was clear that bladder volume affected the doses to certain organs. We focused on the prostate, bladder, rectum, small bowel, and large bowel. Regression coefficients were calculated for variables that correlated strongly with bladder volume (p < 0.05). We found that variation in bladder volume [cm<sup>3</sup>] predicted deviations in the bladder V<sub>70Gy</sub>, V<sub>50Gy</sub>, and V<sub>30Gy</sub> [%];the maximum dose to the small bowel [cGy];and the maximum dose to the large bowel [cGy]. The regression coefficients were -0.065, -0.125, -0.180, -10.22, and -9.831, respectively. We evaluated the impacts of such variation on organ doses. These may be helpful when checking a patient’s bladder volume before daily IMRT for localized prostate cancer.展开更多

A 28-year-old Japanese woman complained of a severe dysmenorrhea. Left ovarian endometriotic cyst and deep infiltrating endometriosis were suspected. Two red-spots were also present in the posterior fornix of vagina. Vaginal cytology with?cytokeratin (CK) 7-immunocytochemistry suggested the presence of infiltrating endometriosis. She underwent left ovarian cystectomy and resection of thickened uterosacral ligaments with vaginal endometriotic spots, under a laparoscope, based on the diagnosis of endometriotic cyst. Histopathology revealed DIE with vaginal invasion. Immunostaining for CK7 was positive for endometriotic cyst, while CK20 was negative. The stromal cells in endometriosis were immunohistochemically positive for CD10. The vaginal fornix was well-healed one month later the surgery. Postoperatively, she got pregnant with her natural intercourse and delivered a healthy 2138 g girl at 36 weeks of gestation.展开更多

Novel treatments against PDAC are desperately needed. Anti-Gal is the most abundant natural antibody in humans,comprising about 1% of immunoglobulins and is also naturally produced in apes and Old World monkeys. The anti-Gal ligand is a carbohydrate antigen called "α-gal epitopes" with the structure Galα1-3Galβ1-4Glc NAc-R. These epitopes are expressed as major carbohydrate antigens in non-primate mammals,prosimians,and New World monkeys. Anti-Gal is exploited in cancer vaccines to increase the immunogenicity of antigen-presenting cells(APCs). Cancer cells or PDAC tumor lysates are processed to express α-gal epitopes. Vaccination with these components results in in vivo opsonization by anti-Gal Ig G in PDAC patients. The Fc portion of the vaccine-bound anti-Gal interacts with Fcγ receptors of APCs,inducing uptake of the vaccine components,transport of the vaccine tumor membranes to draining lymph nodes,and processing and presentation of tumor-associated antigens(TAAs). Cancer vaccines expressing α-gal epitopes elicit strong antibody production against multiple TAAs contained in PDAC cells and induce activation of multiple tumor-specific T cells. Here,we review new areas of clinical importance related to the α-gal epitope/anti-Gal antibody reaction and the advantages in immunotherapy against PDAC.展开更多

Here, we demonstrate that SOX2^+ foregut epithelial cells are prone to oncogenic transformation upon mutagenic insults, such as Kras^G12D and p53 deletion. GFP-based lineage-tracing experiments indicate that SOX2^+ cells are the cells-of-origin of esophagus and stomach hyperplasia. Our observations indicate distinct roles for oncogenic KRAS mutation and P53 deletion. p53 homozygous deletion is required for the acquisition of an invasive potential, and Kras^G12D expression, but not p53 deletion, suffices for tumor formation. Global gene expression analysis reveals secreting factors upregulated in the hyperplasia induced by oncogenic KRAS and highlights a crucial role for the CXCR2 pathway in driving hyperplasia. Collectively, the array of genetic models presented here demonstrate that stratified epithelial cells are susceptible to oncogenic insults, which may lead to a better understanding of tumor initiation and aid in the design of new cancer therapeutics.展开更多

Biomass is commonly used for the production of bio-ethanol by a series of processes such as pretreatment, enzymatic degradation, and fermentation. Hemicellulose, constituting 20 wt-% - 40 wt-% ofbiomass materials, contains various kinds of saccharides known to be bioactive substrates. Practical usage of hemicellulose is generally limited to its conversion to bio-ethanol. Here, we aimed to prepare hemicellulolic oligosaccharides, more valuable products other than ethanol. Therefore, the Hinoki slurry was treated with lime at room temperature for 3 h, and then neutralized with HCI. The resulting sample was treated with 13 types of commercial enzymes, and the saccharides produced in the supernatant were evaluated. The result showed that the commercial enzyme Cellulase SS （Nagase ＆ Co., LTD.） effectively degraded the slurry to produce disaccharides and trisaccharides. Analysis of sugar components by liquid chromatography/mass spectrography （LC/MS） after the derivation with ethyl 4- aminobenzoate （ABEE） showed that mannobiose, manno- Nose, and cellobiose were the major oligosaccharides. These results indicate valuable oligosaccharides can be successfully produced from Hinoki softwood slurry.展开更多

To compute these geometries on noisy intermediate-scalequantum devices, we proposed a strategy that combined a chemistry-inspired spin-restricted ansatz and a new excited statecalculation method called the variational quantum eigensolver under automatically-adjusted constraints (VQE/AC). Unlike theconventional excited state calculation method, called the variational quantum deflation, the VQE/AC does not require the pre-determination of constraint weights and has the potential to describe smooth potential energy surfaces. To validate this strategy,we performed the excited state calculations at the FC and CI geometries of ethylene and phenol blue at the complete active spaceself-consistent field (CASSCF) level of theory, and found that the energy errors were at most 2 kcal mol−1 even on the ibm_kawasakidevice.展开更多

Laser ablated polyynes are separated in size and dispersed in a film of polyvinyl alcohol (PVA), which is stretched to align the trapped linear polyyne molecules inside. As a nature of the structural anisotropy, transition dipole of the UV absorption for polyyne molecules is in parallel with the molecular axis and the absorption occurs only for the electromagnetic wave having the amplitude of its electric vector along the molecular axis. Aligned and fixed orientationally in the solid PVA film, polyyne molecules act as selective absorbers of one of the polarization components of incident light at particular wavelength. Using a light source of linearly polarized UV light, whose direction of polarization is rotatable, angular dependence of the absorption intensity is investigated for the stretched PVA film containing aligned polyyne molecules and analyzed in terms of an order parameter in the theory of linear dichroism.展开更多

Three low-lying states, namely the 0＋ground state, the 2^＋ state at Ex = 3.37 MeV, and the multiplet at around 6 MeV in10 Be, are populated by this one-neutron transfer reaction. These three states in10 Be are clearly discriminated from the -value spectrum, which is rebuilt from energies and angles of the recoil deuterons in coincidence with10 Be. A spectroscopic factor for each state is extracted by comparing the experimental differential cross sections to the theoretical calculation results using the finite range adiabatic distorted wave approximation method with different global nucleon-nucleus potentials. It is found that the newly extracted spectroscopic factors for the 0＋and 2＋states are consistent with the previous ones, but the factor for the multiplet is smaller than the value in the reference, and the possible reason is discussed.展开更多

文摘To test the influence of binder strength, porous concretes with 4 binder strengths between 30.0-135.0 MPa and 5 void ratios between 15%-35% were tested. The results indicated that for the same aggregate, the rates of strength reduction due to the increases in void ratio were the same for binders with different strengths. To study the influence of aggregate size, 3 single size aggregates with nominal sizes of 5.0, 13.0 and 20.0 mm （Nos. 7, 6 and 5 according to JIS A 5001） were used to make porous concrete. The strengths of porous concrete are found to be dependent on aggregate size. The rate of strength reduction of porous concrete with small aggregate size is found to be higher than that with larger aggregate size. At the same void ratio, the strength of porous concrete with large aggregate is larger than that with small aggregate.

Practical usage of hemicellulose is generally limited to its conversion to bio-ethanol. Here, we aimed to prepare hemicellulolic oligosaccharides, more valuable products other than ethanol. Therefore, the Hinoki slurry was treated with lime at room temperature for 3 h, and then neutralized with HCI. The resulting sample was treated with 13 types of commercial enzymes, and the saccharides produced in the supernatant were evaluated. The result showed that the commercial enzyme Cellulase SS （Nagase ＆ Co., LTD.） effectively degraded the slurry to produce disaccharides and trisaccharides. Analysis of sugar components by liquid chromatography/mass spectrography （LC/MS） after the derivation with ethyl 4- aminobenzoate （ABEE） showed that mannobiose, manno- Nose, and cellobiose were the major oligosaccharides. These results indicate valuable oligosaccharides can be successfully produced from Hinoki softwood slurry.
文摘Purpose: To determine if there is a difference in central corneal thickness (CCT) of white and yellow Brazilian patients. Methods: We retrospectively compared the CCT data of yellow patients living in Brazil and white Brazilian patients. CCT was measured with an ultrasound pachymeter (Compuscan P Ultrasonic Pachymeter System model UPC 1000 ). One eye of each patient was randomly selected for statistical analysis. A two sample t

文摘The ground and excited state calculations at key geometries, such as the Frank–Condon (FC) and the conical intersection (CI)geometries, are essential for understanding photophysical properties. To compute these geometries on noisy intermediate-scalequantum devices, we proposed a strategy that combined a chemistry-inspired spin-restricted ansatz and a new excited statecalculation method called the variational quantum eigensolver under automatically-adjusted constraints (VQE/AC). Unlike theconventional excited state calculation method, called the variational quantum deflation, the VQE/AC does not require the pre-determination of constraint weights and has the potential to describe smooth potential energy surfaces. To validate this strategy,we performed the excited state calculations at the FC and CI geometries of ethylene and phenol blue at the complete active spaceself-consistent field (CASSCF) level of theory, and found that the energy errors were at most 2 kcal mol−1 even on the ibm_kawasakidevice.

文摘Electronic absorption bands of conjugated linear carbon chain molecules, namely polyynes H(C≡C)nH (n=5-7), are exploited to devise light-polarizing films applicable to the UV. Laser ablated polyynes are separated in size and dispersed in a film of polyvinyl alcohol (PVA), which is stretched to align the trapped linear polyyne molecules inside. As a nature of the structural anisotropy, transition dipole of the UV absorption for polyyne molecules is in parallel with the molecular axis and the absorption occurs only for the electromagnetic wave having the amplitude of its electric vector along the molecular axis. Aligned and fixed orientationally in the solid PVA film, polyyne molecules act as selective absorbers of one of the polarization components of incident light at particular wavelength. Using a light source of linearly polarized UV light, whose direction of polarization is rotatable, angular dependence of the absorption intensity is investigated for the stretched PVA film containing aligned polyyne molecules and analyzed in terms of an order parameter in the theory of linear dichroism.

文摘A new ^11Be（p,d） transfer reaction experiment is performed in inverse kinematics with a radioactive11 Be beam at26.9 MeV. Three low-lying states, namely the 0＋ground state, the 2^＋ state at Ex = 3.37 MeV, and the multiplet at around 6 MeV in10 Be, are populated by this one-neutron transfer reaction. These three states in10 Be are clearly discriminated from the -value spectrum, which is rebuilt from energies and angles of the recoil deuterons in coincidence with10 Be. A spectroscopic factor for each state is extracted by comparing the experimental differential cross sections to the theoretical calculation results using the finite range adiabatic distorted wave approximation method with different global nucleon-nucleus potentials. It is found that the newly extracted spectroscopic factors for the 0＋and 2＋states are consistent with the previous ones, but the factor for the multiplet is smaller than the value in the reference, and the possible reason is discussed.
