Abstract
The use of cisplatin may cause nephrotoxicity in patients. Hydration solutions supplemented with magnesium could reduce cisplatin-induced nephrotoxicity. In this study, we evaluated the preventive effect of magnesium pre-loading on cisplatin-induced nephrotoxicity in patients with esophageal cancer. We retrospectively evaluated the prevalence of, and risk factors for, nephrotoxicity in 160 patients with esophageal cancer treated with the 5-fluorouracil/cisplatin regimen from 2014 to 2016 with and without magnesium supplementation. Significant differences were observed between the magnesium and non-magnesium groups in terms of frequency of estimated creatinine clearance of grade 2 or higher that was at 4% (n = 3) and 13% (n = 10) (p = 0.027), respectively. The logistic regression analysis revealed that eCcr of grade 2 or higher was significantly associated with the non-magnesium regimen (odds ratio (OR), 4.175; 95% confidence interval (CI) = 1.061-16.430; p = 0.041) and age ≥ 65 years (OR, 13.951; 95% CI = 1.723-112.974; p = 0.014). This study suggests that 20 mEq magnesium pre-loading significantly reduces the prevalence of cisplatin-induced nephrotoxicity. Furthermore, when cisplatin is administered to individuals older than 64 years, a close observation for the onset of cisplatin-induced nephrotoxicity is crucial.

Thymidylate synthase locus LOH in combination with genotype has prognostic and predictive significance in colorectal cancer. Mol Clin Oncol 2021; 15:235. [PMID: 34650802 PMCID: PMC8506693 DOI: 10.3892/mco.2021.2398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Accepted: 07/22/2021] [Indexed: 11/06/2022] Open
Abstract
The aim of the current study was to investigate the prognostic and predictive significance of polymorphisms in the thymidylate synthase (TS) gene, alongside the loss of heterozygocity (LOH) at this gene locus in patients with colorectal cancer. Genotyping was carried out for a variable number tandem repeat (VNTR) polymorphism in the TS 5'-untranslated region, a G/C single nucleotide polymorphism (SNP) located within this VNTR, and for TS LOH status in 246 colorectal cancer and paired normal DNA samples. The results were analyzed in relation to clinicopathological features, including the prognostic and predictive significance of TS genotype in patients who underwent curative surgery. Complete VNTR, SNP and LOH information for TS was obtained in 226 cases. No significant associations were observed between normal tissue TS genotype status and clinicopathological features. LOH of TS was observed in 58% of tumor samples and was associated with poor prognosis independently of clinical stage. Cases exhibiting TS LOH were classified into the three groups of 2R/loss, 3G/loss and 3C/loss. Patients with 3C/loss genotype status had poor outcomes when treated by surgery alone, but their survival was similar to patients with other genotypes following Fluorouracil (5-FU)-based adjuvant chemotherapy. The results suggested that LOH of the TS locus may be a significant prognostic factor in colorectal cancer, with the genotype of the residual allele also demonstrating an influence on prognosis. In conclusion, LOH status should be considered when TS genotype is explored as a potential prognostic and predictive marker for 5-FU-based adjuvant chemotherapy in colorectal cancer.

Abstract
We presented the case of a 63-year-old woman with severe abdominal distention due to recurrent retroperitoneal sarcoma. Further, the rapid progression of the tumor made it difficult to relieve the abdominal distention. Titrated intravenous morphine was administered. Although the dose of morphine was escalated and the patient was sedated, she continued to experience pain. The addition of a continuous epidural analgesic lidocaine to manage the abdominal distention was effective. This case report describes a stepwise approach with continuous epidural analgesia of lidocaine for a bulky tumor- related abdominal distention.

Abstract
AbstractObjectiveIn this study, we evaluated brain perfusion in patients with first-episode medicated schizophrenia using the new analytical method, statistical parametric mapping (SPM) applied to single photon emission computed tomography (SPECT).MethodWe performed SPECT with 99-Tc-ethyl cysteinate dimer (99mTc-ECD) of the brain and magnetic resonance imaging (MRI) in patients with schizophrenia (n = 30) and control subjects matched for age and gender (n = 37). A voxel-by-voxel group analysis was performed using SPM2 (Z > 3.0, P < 0.001, uncorrected for multiple comparisons).ResultIn comparison with control subjects, the volumes of the bilateral frontal areas were found to be decreased on MRI. Blood flow was found to be reduced in the bilateral temporal areas in the patients with schizophrenia on SPECT.ConclusionIn this study, patients with first-episode schizophrenia appeared to have significant bilateral temporal hypoperfusion, although temporal volumes were not significantly decreased in comparison with control subjects. Abnormality of temporal lobe blood flow in schizophrenia may show that functional changes occur earlier than structural changes, and may assist in the diagnosis of schizophrenia.

Abstract
Abstract
Background/Introduction
Outpatient cardiac rehabilitation (CR) is commonly recommended for patients with acute myocardial infarction (AMI). However, the survival benefit has recently been contested, especially with no survival benefit having been found in non-Western countries.
Purpose
To investigate whether outpatient CR, under current real-world clinical practice, is associated with lower mortality and morbidity risks in patients with AMI.
Methods
The retrospective cohort study was conducted from January 2011 to June 2016 (final date of follow-up: July 31, 2016) with a nation-wide administrative database for acute-care hospitals in Japan. Data for 7,411 patients were analyzed, with 5,654 fulfilling the inclusion criteria of being admitted for AMI and receiving both percutaneous coronary intervention and inpatient CR between January 2011 and December 2014. We compared patients who participated in outpatient CR at least once within 180 days of discharge and who did not. To account for measured baseline imbalances between outpatient CR participants and non-participants, 1:1 propensity-score matching was performed. The primary outcome was a composite of all-cause death and recurrence of AMI after the landmark time-point of day 180 after discharge. Secondary outcomes included all-cause death, recurrence of AMI, and heart failure.
Results
Among 5,654 patients (mean [SD] age, 66.8 [12.4] years; 21.2% female; median follow-up period [IQR] 1.44 [0.87 to 2.27] years), 730 (12.9%) received outpatient CR. Of 1,458 propensity-score matched patients, outpatient CR participants did not show a significantly lower risk of the primary outcome than non-participants (1.38 vs. 2.12 per 100 patient-years; hazard ratio [HR], 0.71 [95% CI, 0.32 to 1.61]). Similarly, outpatient CR participation was not associated with lower risks of all-cause death (0.68 vs. 1.31 per 100 patient-years; HR, 0.83 [95% CI, 0.25 to 2.73]), recurrence of AMI (0.69 vs. 0.88 per 100 patient-years; HR, 0.56 [95% CI, 0.19 to 1.66]) or heart failure (2.01 vs. 2.06 per 100 patient-years; HR, 0.89 [95% CI, 0.47 to 1.72]), respectively.
Conclusion
Among patients with AMI who received percutaneous coronary intervention and inpatient CR, outpatient CR was not associated with lower risks of mortality and morbidities. The survival benefit of outpatient CR should be reaffirmed under current real-world clinical practice, especially in non-Western countries.

Abstract
Abstract
Introduction
Asian dust (AD) is one of the health care problems because AD increases risk for mortality, respiratory, and cardiovascular disease. Previous animal studies showed that particulate matter from AD induced oxidative stress and systemic inflammation, increased blood pressure and heart rate, and decreased cardiac contraction. However, few reports show association of AD with increased blood pressure in human healthy subjects.
Purpose
The aim of this study was to investigate effects of AD on blood pressure and blood cell counts in human.
Methods
Using generalized linear models, we estimated the association between short-term exposure to AD and systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) and white blood cell (WBC) count in 296,168 participants aged 20 and older (men n=168,579, 56.9%) who underwent medical check-ups and had no anti-hypertensive agents between April 2005 and March 2015 in a health check-up center in Japan. AD days were the days on which AD events occurred, which were defined as decreased visibility (<10km) due to AD monitored by local meteorological observatory. Propensity score matching analysis was performed to reduce the effects of possible confounders such as age, sex, mean temperature, humidity. In multivariable generalized linear models, data of other air pollutant such as SO2, NO2, Ox or suspended particulate matter was used as covariate.
Results
During study period, 61 AD days were observed, and there were 4,670 participants undergoing medical check-ups on AD days. In the propensity score matched population (n=4,670, each), short-term exposure to AD was significantly associated with an increased risk of higher SBP, DBP, HR, or WBC count [β=1.303, 95% confidence interval (CI) 0.577 to 2.029 for SBP, β=0.630, 95% CI 0.122 to 1.138 for DBP, β=0.987, 95% CI 0.410 to 1.563 for HR, β=150.0, 95% CI 64.9 to 235.1 for WBC]. These significant associations were also observed in two-pollutant models. In subgroup analysis according to age, AD exposure had greater impact on SBP, DBP, and HR in younger people (20 to 40 years old), but WBC count in middle-high age (51 years and older).
GLM analysis according to age category
Conclusions
The present study showed that short-term exposure to AD was associated with higher SBP, DBP, HR and WBC count. Short-term exposure to AD may exacerbate sympathetic nervous system for the young and immune system for the elderly.

Abstract
Abstract
Background
Asian dust (AD) is considered as one of air pollution that increases risk of acute myocardial infarction (AMI). However, it has not been elucidated whether AD might increase the risk of myocardial infarction with nonobstructive coronary arteries (MINOCA).
Methods
A time-stratified case-crossover design and conditional logistic regression models was used to investigate the association between short-term exposure to AD and admission of AMI during the spring months in a nationwide administrative Diagnostic Procedure Combination (DPC) database, the Japanese Of All cardiac and vascular Diseases (JROAD)-DPC, between April 2012 through March 2016. MINOCA was defined as AMI having angiography without revascularization and coronary atherosclerosis, whereas myocardial infarction with obstructive coronary artery disease (MI-CAD) was AMI with revascularization and/or coronary atherosclerosis. Data for AD events, air pollutants (PM2.5, Ox, NO2, SO2), and meteorological variables were obtained from the nearest monitoring station of the hospital.
Results
During the study period, 3,233 MINOCA and 27,202 MI-CAD patients were identified from 30,435 AMI patients. Although the occurrence of AD events 2 days before the admission was not associated with the admission of AMI and MI-CAD, the AD events was significantly associated with the admission of MINOCA with adjustment for meteorological variables and each air pollutant. In subgroup analysis of MINOCA, patients without low ADL was associated with higher risk of the admission due to AD exposure than those with low ADL, with significant interaction.
Conclusions
AD events might be more likely to trigger onset of MINOCA than MI-CAD.

Abstract
61 Background: It is difficult to know when the best timing is to transfer terminally ill cancer patients from hospitals to palliative hospice home care for their quality of life to death. This study aimed to articulate the best time for medical teams working in hospitals to refer their terminally ill cancer patients to palliative home care. Methods: A statistical analysis of a survey was conducted with 1,055 surviving families whose members had died with palliative home care from 1995 to 2014. The questionnaire included the following 8 contents: 1. transfer timing from hospitalization to the home care; A. appropriate, B. too late, C. too early; and the contextual items ware, 2. peacefulness of patient at dying, 3. peacefulness of patient all through the care, 4. physical pain, 5. mental pain, 6. spiritual pain, 7. alleviation of family sufferings, 8. satisfaction of family as care-givers. The response rate is 31% (311 persons). However, we excluded responses without names on the questionnaire, of non-cancer patients, with death location out of home, and without answer to question 1, resulting in 166 responses for analysis. Results: Focusing on the question 1, number of responders are A; 113 (68%), B; 52 (31%), C; 1 (0.6%). The medians of home care days to death are A; 66, B; 23, C; analysis impossible. Comparison of respondents’ satisfaction according to number of days of palliative home care revealed that 89.4% people with two months or more before their patients’ death were satisfied (A), while 10.6% of those who had less than two month were unsatisfied (B+C). Conclusions: Most surviving families were satisfied if they had two months or more for palliative home care. This survey suggests the relevancy to start preparation for discharge that enables the patients to stay home with their family members for two months or more. [Table: see text]

Sex-based differences in CD103 + dendritic cells promote female-predominant Th2 cytokine production during allergic asthma. Clin Exp Allergy 2018; 48:379-393.

Abstract
BACKGROUND Gender disparities in adult patients with asthma regarding its prevalence and severity are mainly due to enhanced type 2 T-helper (Th2) cytokine production in female patients compared to that in male patients. However, the pathways mediating this effect remain unclear. OBJECTIVE We aimed to determine the roles of two major subsets of dendritic cells (DCs) in females, specifically those displaying CD11b or CD103, during enhanced Th2 priming after allergen exposure, using an ovalbumin-induced asthma mouse model. METHODS Sex-based differences in the number of DCs at inflamed sites, costimulatory molecule expression on DCs, and the ability of DCs to differentiate naïve CD4+ T cells into Th2 population were evaluated after allergen exposure in asthmatic mice. In addition, we assessed the role of 17β-oestradiol in CD103+ DC function during Th2 priming in vitro. RESULTS The number of CD11bhigh DCs and CD103+ DCs in the lung and bronchial lymph node (BLN) was increased to a greater extent in female mice than in male mice at 16 to 20 hours after ovalbumin (OVA) inhalation. In BLNs, CD86 and I-A/I-E expression levels and antigen uptake ability in CD103+ DCs, but not in CD11bhigh DCs, were greater in female mice than in male mice. Furthermore, CD4+ T cells cultured with CD103+ DCs from female mice produced higher levels of interleukin (IL)-4, IL-5, and IL-13, compared with CD4+ T cells cultured with CD103+ DCs from male mice. The 17β-oestradiol-oriented enhancement of CD86 expression on CD103+ DCs after allergen exposure induced the enhanced IL-5 production from CD4+ T cells. CONCLUSIONS AND CLINICAL RELEVANCE These findings suggest that with regard to asthma, enhanced Th2 cytokine production in females might be attributed to 17β-oestradiol-mediated Th2-oriented CD103+ DCs in the BLN.

Abstract
In this study, a co-culture system of hepatocytes and bone marrow cells (BMCs) was developed and characterized for the expression and maintenance of ammonia metabolism and albumin secretion activities. A culture medium supplemented with epidermal growth factor, insulin, L-proline, hydrocortisone and 20 % (v/v) heat-inactivated fetal bovine serum was developed. In addition to adhesive bone marrow cells, the co-existence of non-adhesive bone marrow cells was effective in expressing liver-specific functions for at least 3 weeks. On the other hand, experiments with Transwell in which cultured cells were separated by a semi-permeable membrane, suggested that soluble factors secreted by BMCs are the key components in the functional enhancement of cells. Furthermore, direct contact between hepatocytes and BMCs enhanced the formation of spheroids and the expression of liver specific functions. These results indicate that this co-culture system is promising in, for example, bioartificial liver, regenerative medicine, and liver function simulator applications.

Abstract
Introduction The dialyzer apparatus has been widely used as an artificial kidney in medical treatment. However, side effects such as amyloidosis have occurred during long-term treatment. Therefore, we focused on developing a hybrid artificial kidney with a filtration and reabsorption apparatus, but it was found that cells spread extensively and it is difficult to maintain a uniform monolayer with a regular cell shape on a collagen-coated substrate. The purpose of this study was to improve cell adhesion, uniform stable monolayer formation and active transport function by immobilization of arginine-glycine-aspartic acid (RGD) on the culture substratum. Materials and Methods Polycarbonate semipermeable membranes were coated with collagen, fibronectin, laminin and synthetic polypeptide, including RGD (Pronectin F). Cell adhesion and digoxin transport were estimated using a renal proximal tubule cell line that overexpressed the P-glycoprotein gene. Results and Discussion Under initial and confluent conditions, immobilized cell density in Pronectin F-coated wells was higher than that under other conditions. Transepithelial electrical resistance and digoxin transport activity on Pronectin F-coated membranes were the highest of all conditions. This might have been caused by uniform cell morphology and high cell density.

Abstract
OBJECTIVE There is some evidence that clozapine is significantly underutilised. Also, clozapine use is thought to vary by country, but so far no international study has assessed trends in clozapine prescribing. Therefore, this study aimed to assess clozapine use trends on an international scale, using standardised criteria for data analysis. METHOD A repeated cross-sectional design was applied to data extracts (2005-2014) from 17 countries worldwide. RESULTS In 2014, overall clozapine use prevalence was greatest in Finland (189.2/100 000 persons) and in New Zealand (116.3/100 000), and lowest in the Japanese cohort (0.6/100 000), and in the privately insured US cohort (14.0/100 000). From 2005 to 2014, clozapine use increased in almost all studied countries (relative increase: 7.8-197.2%). In most countries, clozapine use was highest in 40-59-year-olds (range: 0.6/100 000 (Japan) to 344.8/100 000 (Finland)). In youths (10-19 years), clozapine use was highest in Finland (24.7/100 000) and in the publicly insured US cohort (15.5/100 000). CONCLUSION While clozapine use has increased in most studied countries over recent years, clozapine is still underutilised in many countries, with clozapine utilisation patterns differing significantly between countries. Future research should address the implementation of interventions designed to facilitate increased clozapine utilisation.

Health state utility values and patient-reported outcomes before and after vertebral and non-vertebral fractures in an osteoporosis clinical trial. Osteoporos Int 2017; 28:1893-1901. [PMID: 28265719 DOI: 10.1007/s00198-017-3966-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2016] [Accepted: 02/09/2017] [Indexed: 10/20/2022]
Abstract
UNLABELLED We assessed the health state utility value (HSUV) reductions associated with vertebral fractures using data collected in the Japanese Osteoporosis Intervention Trial-03 (JOINT-03). Our analysis revealed that assessment of HSUVs after morphometric vertebral fracture is important to capture the burden of vertebral fractures. INTRODUCTION Evaluation of the HSUV after fracture is important to calculate the quality-adjusted life years (QALYs) of osteoporosis patients, which is essential information in the context of health economic evaluation. METHODS JOINT-03 study patients were aged ≥65 years and treated with risedronate and vitamin K2 or risedronate alone. Radiographic information and patient-reported outcomes measured by EQ-5D and a visual analogue scale (VAS) were assessed at registration and followed up after 6, 12, and 24 months. According to differences among the dates of these assessments and the radiographic information, we classified the follow-up HSUVs calculated based on EQ-5D results into before or after fracture categories regardless of clinical symptoms. RESULTS Among 2922 follow-up HSUVs, 201 HSUVs were categorized as HSUVs that were observed after incident vertebral fractures on X-ray films. The median time from the detection of an incident vertebral fracture until the EQ-5D assessment was 53 days (25th percentile, 0 day; 75th percentile, 357 days). The impact of incident vertebral fractures on HSUVs was quantified as -0.03. Among the five health profile domains on the EQ-5D, an incident vertebral fracture had significant effects on anxiety/depression, self-care, and usual activities. CONCLUSIONS The results suggest that incident morphometric vertebral fracture was associated with impairment of the HSUV for patients with osteoporosis not only immediately but also several months after the fracture.

Abstract
BACKGROUND AND PURPOSE Previous studies have reported that diabetes is a risk factor for both all-cause and vascular dementia; however, diabetes as a risk factor for Alzheimer's disease (AD) remains controversial. Therefore, the aim was to elucidate the association between diabetes and early-onset AD. METHODS A case-control study was conducted using a population-based database that included medical and pharmacy claims and insurance eligibility data, from beneficiaries of corporate employees and their dependent family members. Cases were aged 40-64 years and were first prescribed medications for AD between 2005 and 2016. Up to four controls matched for age, sex and hospital type were included for each case. Data were analyzed using conditional logistic regression and compared between the sexes. RESULTS Data from 371 patients with AD (mean age 56.3 ± 5.3 years; 48% female) and 1484 controls were analyzed. Use of antidepressants, antipsychotics and antithrombotics during the index month was higher amongst patients with AD (19.4%, 34.5% and 11.3%, respectively) than amongst controls (2.9%, 10.3% and 7.3%, respectively). Our findings suggest no evidence for an association between diabetes and risk of early-onset AD (adjusted odds ratio 1.31; 95% confidence interval 0.90-1.92). In the subgroup analyses, adjusted odds ratios in patients with diabetes were 0.73 (95% confidence interval 0.38-1.39) and 1.68 (95% confidence interval 1.06-2.67) for female and male patients, respectively. CONCLUSIONS There is no apparent association between diabetes and risk of early-onset AD in the total study population, although a weak association was observed amongst male patients.

Abstract
BACKGROUND The molecular profiles of tumors may inform the selection of appropriate targeted therapies. Circulating tumor cells (CTCs) reflect the real-time status of tumor genotypes. CTCs exhibit high genetic heterogeneity within a patient; accordingly, the analysis of individual CTCs, including their heterogeneity, may enable more precise treatments. We analyzed KRAS mutations in single CTCs from patients with metastatic colorectal cancer (mCRC) using a new single-cell picking system. METHODS Blood samples were obtained from 61 patients with mCRC. CTCs were enriched and fluorescently labeled using the CellSearch® System. They were recovered using the single-cell picking system based on the fluorescence intensity of marker dyes. Single CTCs and tumor tissue samples were examined for mutations in codons 12 and 13 of the KRAS gene. RESULTS CTCs were detected in 27 of 61 patients with mCRC. We isolated at least two CTCs from 15 of 27 patients. KRAS genotype was evaluated in a total of 284 CTCs from 11 patients, and 15 cells with mutations were identified in four patients. In 10 of 11 patients, the KRAS status was the same in the primary tumor and CTCs. In one patient, the KRAS status was discordant between the primary tumor and CTCs. In two patients, different KRAS mutations were found among individual CTCs. CONCLUSIONS We successfully isolated single CTCs and detected KRAS mutations in individual cells from clinical samples using a novel application of single-cell isolation system. Using the system, we detected CTC heterozygosity and heterogeneity in KRAS status among CTCs within a patient and between CTCs and tumor tissues.

Comparison of the quantitative analysis performance between pulsed voltage atom probe and pulsed laser atom probe. Ultramicroscopy 2017; 175:105-110.

Abstract
The difference in quantitative analysis performance between the voltage-mode and laser-mode of a local electrode atom probe (LEAP3000X HR) was investigated using a Fe-Cu binary model alloy. Solute copper atoms in ferritic iron preferentially field evaporate because of their significantly lower evaporation field than the matrix iron, and thus, the apparent concentration of solute copper tends to be lower than the actual concentration. However, in voltage-mode, the apparent concentration was higher than the actual concentration at 40K or less due to a detection loss of matrix iron, and the concentration decreased with increasing specimen temperature due to the preferential evaporation of solute copper. On the other hand, in laser-mode, the apparent concentration never exceeded the actual concentration, even at lower temperatures (20K), and this mode showed better quantitative performance over a wide range of specimen temperatures. These results indicate that the pulsed laser atom probe prevents both detection loss and preferential evaporation under a wide range of measurement conditions.

Abstract
Photosystem II (PSII) is a membrane protein complex that performs light-induced electron transfer and oxygen evolution from water. PSII consists of 19 or 20 subunits in its crystal form and binds various cofactors such as chlorophyll a, plastoquinone, carotenoid, and lipids. After initial light excitation, the charge separation produces an electron, which is transferred to a plastoquinone molecule (QA) and then to another plastoquinone (QB). PsbM is a low-molecular-weight subunit with one transmembrane helix, and is located in the monomer–monomer interface of the PSII dimer. The function of PsbM has been reported to be stabilization of the PSII dimer and maintenance of electron transfer efficiency of PSII based on previous X-ray crystal structure analysis at a resolution of 4.2 Å. In order to elucidate the structure–function relationships of PsbM in detail, we improved the quality of PSII crystals from a PsbM-deleted mutant (ΔPsbM-PSII) of Thermosynechococcus elongatus, and succeeded in improving the diffraction quality to a resolution of 2.2 Å. X-ray crystal structure analysis of ΔPsbM-PSII showed that electron densities for the PsbM subunit and neighboring carotenoid and detergent molecules were absent in the monomer–monomer interface. The overall structure of ΔPsbM-PSII was similar to wild-type PSII, but the arrangement of the hydrophobic transmembrane subunits was significantly changed by the deletion of PsbM, resulting in a slight widening of the lipid hole involving QB. The lipid hole-widening further induced structural changes of the bicarbonate ion coordinated to the non-heme Fe(ii) atom and destabilized the polypeptide chains around the QB binding site located far from the position of PsbM. The fluorescence decay measurement indicated that the electron transfer rate from QA to QB was decreased in ΔPsbM-PSII compared with wild-type PSII. The functional change in electron transfer efficiency was fully interpreted based on structural changes caused by the deletion of the PsbM subunit.

Abstract
Transparent ceramics are important for scientific and industrial applications because of the superior optical and mechanical properties. It has been suggested that optical transparency and mechanical strength are substantially enhanced if transparent ceramics with nano-crystals are available. However, synthesis of the highly transparent nano-crystalline ceramics has been difficult using conventional sintering techniques at relatively low pressures. Here we show direct conversion from bulk glass starting material in mutianvil high-pressure apparatus leads to pore-free nano-polycrystalline silicate garnet at pressures above ∼10 GPa in a limited temperature range around 1,400 °C. The synthesized nano-polycrystalline garnet is optically as transparent as the single crystal for almost the entire visible light range and harder than the single crystal by ∼30%. The ultrahigh-pressure conversion technique should provide novel functional ceramics having various crystal structures, including those of high-pressure phases, as well as ideal specimens for some mineral physics applications.
It is suggested that the optical and mechanical properties of transparent ceramics become very favourable if they can be synthesized as nanocrystals. Here, the authors report direct conversion of bulk glass starting material to pore-free nano-polycrystalline silicate garnet at high pressure and temperature.

Abstract
Abstract
Background: FOLFIRI plus bevacizumab (BV) is widely used as second-line chemotherapy for patients with metastatic colorectal cancer (mCRC) previously treated with FOLFOX/XELOX plus bevacizumab. However, there is insufficient data characterizing the effectiveness of administration of fluoropyrimidine beyond first disease progression. FOLFIRI requires using a CV catheter. Oral fluoropyrimidine may cause severe diarrhea when administered with irinotecan (CPT-11). CPT-11+BV may overcome those problems.
Methods: Patients with mCRC previously treated with at least four courses of fluoropyrimidine, oxaliplatin, and bevacizumab were designated to receive 150 mg/m2 of CPT-11 and 10 mg/kg of BV, every 2 weeks as second-line therapy. The primary endpoint was progression-free survival (PFS), and secondary endpoints included response rate (RR), overall survival (OS), and adverse events.
Results: Thirty patients from six institutes were enrolled from March 2011 to January 2014. Twenty-five (83.3%) patients were refractory to first-line therapy and eight patients (16.6%) were unable to tolerate first-line therapy. The median PFS was 5.7 months (95% CI; 4.2-7.3 months) and the RR was 6.7% (range, 0.8-22.1%. Grades 3-4 adverse events included leucopenia (36.7%), neutropenia (50%), thrombocytopenia (26.7%), anemia (30%), diarrhea (3.3%), anorexia (6.7%), and hypertension (3.3%). Relative dose intensities were 94.5% and 96.3% for CPT-11 and BV, respectively. Median OS was 11.8 months (6.3 months-not reached).
Conclusions: Administration of CPT-11 plus BV to patients with mCRC achieved comparable efficacy with relatively lower toxicities compared with the results of previous studies using FOLFIRI plus BV as second-line therapy. The dose intensity of CPT-11 was judged satisfactory. Clinical trial information: UMIN000005228

Abstract
BACKGROUND FOLFIRI and FOLFOX have shown equivalent efficacy for metastatic colorectal cancer (mCRC), but their comparative effectiveness is unknown when combined with bevacizumab. PATIENTS AND METHODS WJOG4407G was a randomized, open-label, phase III trial conducted in Japan. Patients with previously untreated mCRC were randomized 1:1 to receive either FOLFIRI plus bevacizumab (FOLFIRI + Bev) or mFOLFOX6 plus bevacizumab (mFOLFOX6 + Bev), stratified by institution, adjuvant chemotherapy, and liver-limited disease. The primary end point was non-inferiority of FOLFIRI + Bev to mFOLFOX6 + Bev in progression-free survival (PFS), with an expected hazard ratio (HR) of 0.9 and non-inferiority margin of 1.25 (power 0.85, one-sided α-error 0.025). The secondary end points were response rate (RR), overall survival (OS), safety, and quality of life (QoL) during 18 months. This trial is registered to the University Hospital Medical Information Network, number UMIN000001396. RESULTS Among 402 patients enrolled from September 2008 to January 2012, 395 patients were eligible for efficacy analysis. The median PFS for FOLFIRI + Bev (n = 197) and mFOLFOX6 + Bev (n = 198) were 12.1 and 10.7 months, respectively [HR, 0.905; 95% confidence interval (CI) 0.723-1.133; P = 0.003 for non-inferiority]. The median OS for FOLFIRI + Bev and mFOLFOX6 + Bev were 31.4 and 30.1 months, respectively (HR, 0.990; 95% CI 0.785-1.249). The best overall RRs were 64% for FOLFIRI + Bev and 62% for mFOLFOX6 + Bev. The common grade 3 or higher adverse events were leukopenia (11% in FOLFIRI + Bev/5% in mFOLFOX6 + Bev), neutropenia (46%/35%), diarrhea (9%/5%), febrile neutropenia (5%/2%), peripheral neuropathy (0%/22%), and venous thromboembolism (6%/2%). The QoL assessed by FACT-C (TOI-PFC) and FACT/GOG-Ntx was favorable for FOLFIRI + Bev during 18 months. CONCLUSION FOLFIRI plus bevacizumab was non-inferior for PFS, compared with mFOLFOX6 plus bevacizumab, as the first-line systemic treatment for mCRC. CLINICAL TRIALS NUMBER UMIN000001396.

Abstract
Triclosan (TCS) is an active antimicrobial ingredient used in many household products, such as skin creams and toothpaste. It is produced in high volumes, and humans are directly exposed to it and dispose it on a daily basis. TCS has been found to contaminate water worldwide. This study aimed to understand the potential developmental and metabolic abnormalities caused by TCS exposure by using zebrafish as the experimental model. Four developmental stages (70-85% epiboly, 10-12 somite, prim-5, and 5dpf) were selected to perform in situ hybridization staining to investigate the effects of TCS on dorsal ventral patterning, segmentation, brain development, and organ formation. Results showed, in terms of developmental toxicology, that neither phenotypic nor molecular changes were found after 5 days of 250μg/L TCS exposure. However, such dosage of TCS exposure resulted in lipid droplet accumulation in the yolk sac, which might due to the deregulated mRNA expression level of beta-oxidation transcripts. This study showed that 250μg/L TCS exposure does not affect normal embryogenesis or organogenesis; however, there are concerns regarding possible impairment of lipid metabolism.

Abstract
AIM To compare the multidetector-row computed tomography (MDCT) findings of IgG4-related sclerosing cholangitis (IgG4-SC) and extrahepatic cholangiocarcinoma (EH-CCA). MATERIALS AND METHODS Two radiologists who had no knowledge of the patients' clinical information retrospectively evaluated the CT findings of patients with IgG4-SC (n=33) and EH-CCA (n=39) on a consensus basis. Another radiologist measured the biliary lesions. IgG4-SC was diagnosed using the Japan Biliary Association criteria (2012) or the Mayo Clinic's HISORt criteria. EH-CCA was diagnosed based on surgical findings. RESULTS Compared with EH-CCA, IgG4-SC exhibited the following findings significantly more frequently: (a) wall thickening alone, (b) concentric wall thickening, (c) smooth inner margins, (d) homogeneous attenuation in the arterial phase, (e) a lesion involving the intrapancreatic bile duct, (f) smooth outer margins, (g) fully visible lumen, (h) a funnel-shaped proximal bile duct, (i) skip lesions, and (j) abnormal pancreatic findings. Conversely, (k) dual-layered attenuation in all phases was significantly more common in EH-CCA. The specificity values of parameters (e-k) were >80%. Regarding dimensions, (l) the biliary lesions were longer in IgG4-SC than in EH-CCA. (m) The diameters of the dilated proximal common bile duct and (n) the dilated proximal intrahepatic bile duct were smaller in IgG4-SC than in EH-CCA. CONCLUSION A number of CT findings are useful for differentiating between IgG4-SC and EH-CCA. CT findings (e-k) are particularly useful for this purpose.

Observation of co-segregation of titanium and boron at the interface between recrystallized and unrecrystallized grains in cold-rolled interstitial-free steel sheets.

Abstract
It has been reported that the addition of ppm levels of B strongly retarded the growth of recrystallized grain into unrecrystallized grains in the process of cold-rolling and annealing of Ti-added interstitial-free (IF) ferritic steels. This phenomenon was explained by solute drag effect based on the assumption that, during annealing, B atoms segregate at the interface between recrystallized and unrecrystallized grains where they interact with Ti atoms. To verify this, atom probe tomography analysis of the interface was performed in Ti-added IF steels with and without B addition. Needle tips containing the interface identified from electron backscattering diffraction analysis, were produced by focused ion beam milling with the lift-out method. To increase the experiment reliability, the misorientation angle of the aimed interface was compared with that estimated by field ion microscopy analysis. Considerable amount of Ti segregation was observed at the interface in the steel without B addition, which increased with increasing amount of B segregation in the steel with B addition. The results suggest that the retardation of the interface migration was caused by solute drag effect based on the simultaneous co-segregation of Ti and B due to their attractive interaction.

Full geometry optimizations followed by the vibrational analysis were performed for eight spin configurations of the CaMn4O4X(H2O)3Y (X = O, OH; Y = H2O, OH) cluster in the S1 and S3 states of the oxygen evolution complex (OEC) of photosystem II (PSII). The energy gaps among these configurations obtained by vertical, adiabatic and adiabatic plus zero-point-energy (ZPE) correction procedures have been used for computation of the effective exchange integrals (J) in the spin Hamiltonian model. The J values are calculated by the (1) analytical method and the (2) generalized approximate spin projection (AP) method that eliminates the spin contamination errors of UB3LYP solutions. Using J values derived from these methods, exact diagonalization of the spin Hamiltonian matrix was carried out, yielding excitation energies and spin densities of the ground and lower-excited states of the cluster. The obtained results for the right (R)- and left (L)-opened structures in the S1 and S3 states are found to be consistent with available optical and magnetic experimental results. Implications of the computational results are discussed in relation to (a) the necessity of the exact diagonalization for computations of reliable energy levels, (b) magneto-structural correlations in the CaMn4O5 cluster of the OEC of PSII, (c) structural symmetry breaking in the S1 and S3 states, and (d) the right- and left-handed scenarios for the O-O bond formation for water oxidation.

Effects of ouabain on respiratory rhythm generation in brainstem-spinal cord preparation from newborn rats and in decerebrate and arterially perfused in situ preparation from juvenile rats. Neuroscience 2014; 286:404-11. [PMID: 25512246 DOI: 10.1016/j.neuroscience.2014.12.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2014] [Revised: 10/31/2014] [Accepted: 12/05/2014] [Indexed: 11/25/2022]
Abstract
The significance of Na/K-ATPase on respiratory rhythm generation is not well understood. We investigated the effects of the Na/K-ATPase blocker, ouabain, on respiratory rhythm. Experiments were performed with brainstem-spinal cord preparation from 0 to 3-day-old Wistar rats and with decerebrate and arterially perfused in situ preparation from juvenile rats (postnatal day 11-13). Newborn rat preparations were superfused at a rate of 3.0 ml/min with artificial cerebrospinal fluid, equilibrated with 95% O2 and 5% CO2, pH 7.4, at 26-27 °C. Inspiratory activity was monitored from the fourth cervical ventral root (C4). Application of ouabain (15-20 min) resulted in a dose-dependent increase in the burst rate of C4 inspiratory activity. After washout, the burst rate further increased to reach quasi-maximum values under each condition (e.g. 183% of control in 1 μM, 253% in 10 μM, and 303% in 20 μM at 30 min washout). Inspiratory or pre-inspiratory neurons in the rostral ventrolateral medulla were depolarized. We obtained similar results (i.e. increased phrenic burst rate) in an in situ perfused preparation of juvenile rats. Genes encoding the Na/K-ATPase α subunit were expressed in the region of the parafacial respiratory group (pFRG) in neonatal rats, suggesting that cells (neurons and/or glias) in the pFRG were one of the targets of ouabain. We concluded that Na/K-ATPase activity could be an important factor in respiratory rhythm modulation.

The Tol2 transposon system mediates the genetic engineering of T-cells with CD19-specific chimeric antigen receptors for B-cell malignancies. Gene Ther 2014; 22:209-15.

Abstract
Engineered T-cell therapy using a CD19-specific chimeric antigen receptor (CD19-CAR) is a promising strategy for the treatment of advanced B-cell malignancies. Gene transfer of CARs to T-cells has widely relied on retroviral vectors, but transposon-based gene transfer has recently emerged as a suitable nonviral method to mediate stable transgene expression. The advantages of transposon vectors compared with viral vectors include their simplicity and cost-effectiveness. We used the Tol2 transposon system to stably transfer CD19-CAR into human T-cells. Normal human peripheral blood lymphocytes were co-nucleofected with the Tol2 transposon donor plasmid carrying CD19-CAR and the transposase expression plasmid and were selectively propagated on NIH3T3 cells expressing human CD19. Expanded CD3(+) T-cells with stable and high-level transgene expression (~95%) produced interferon-γ upon stimulation with CD19 and specifically lysed Raji cells, a CD19(+) human B-cell lymphoma cell line. Adoptive transfer of these T-cells suppressed tumor progression in Raji tumor-bearing Rag2(-/-)γc(-/-) immunodeficient mice compared with control mice. These results demonstrate that the Tol2 transposon system could be used to express CD19-CAR in genetically engineered T-cells for the treatment of refractory B-cell malignancies.
