Model tests were carried out to study the deformation characteristics of abutments during liquefaction. In the tests, fine sand was used to model the saturated ground and the embankment. The model constructed inside the box was subjected to sinusoidal vibration with the help of a shaking table. The variation of pore water pressure, the earth pressure and the acceleration were measured with different kinds of transducers and the deformed pattern of the model was observed through a video camera. In addition to the comparison and estimation of the earthquake resistance of various abutments, the effect of the sheet pile method with respect to the stability of abutments constructed on embankments was also investigated.

- Abstract
A biomembrane-related fibrillogenesis of Amyloid β from Alzheimer' disease (Aβ) is closely related to its accumulation behavior. A binding property of Aβ peptides from Alzheimer' disease to lipid membranes was then classified by a quartz crystal microbalance (QCM) method combined with an immobilization technique using thiol self-assembled membrane. The accumulated amounts of Aβ, Δf
max , was determined from the measurement of the maximal frequency reduction using QCM. The plots of Δfmax to Aβ concentration gave the slope and saturated value of Δfmax , (Δfmax )sat that are the parameters for binding property of Aβ to lipid membranes. Therefore, the Aβ-binding property on lipid membranes was classified by the slope and (Δfmax )sat . The plural lipid system was described as X + Y where X = L1 , L1 /L2 , and L1 /L2 /L3 . The slope and (Δfmax )sat values plotted as a function of mixing ratio of Y to X was classified on a basis of the lever principle (LP). The LP violation observed in both parameters resulted from the formation of the crevice or pothole, as Aβ-specific binding site, generated at the boundary between ld and lo phases. The LP violation observed only in the slope resulted from glycolipid-rich domain acting as Aβ-specific binding site. Furthermore, lipid planar membranes indicating strong LP violation favored strong fibrillogenesis. Especially, lipid planar membranes indicating the LP violation only in the slope induced lateral aggregated and spherulitic fibrillar aggregates. Thus, the classification of Aβ binding property on lipid membranes appeared to be related to the fibrillogenesis with a certain morphology., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

- Abstract
Objective: Weight loss (WL) is the most common symptom among patients with Parkinson's disease (PD) and has been reported to start several years before the diagnosis of PD. The relationship between WL and PD treatment is complex. This study aimed to characterize the impact of PD treatment on WL and find clues to establish the administration of nutrition for patients with PD., Materials and Methods: Eighty-two patients with PD (mean age, 58.4 ± 10.2 years; mean Hoehn and Yahr stage, 3.2 ± 0.7) were recruited. Their treatments included deep brain stimulation (DBS) therapy (n = 34), levodopa/carbidopa intestinal gel (LCIG) therapy (n = 13), and oral medication alone (n = 35). Based on the medical records, the age of onset, disease duration, treatment options, videofluoroscopic dysphagia scale, blood test results, and weight change were collected., Results: The median WL per year and rate of WL were -1.0 ± 2.8 kg and -1.9 ± 4.7 %, respectively. Most patients (93 %) were classified into normal nutrition and mild malnutrition groups by their CONUT scores. The median WL of the DBS group was significantly lower than that of the oral medication alone group (p < 0.01). The rate of WL showed a significant negative correlation with the age of onset (rho = -0.328, p = 0.003), but showed a significant positive correlation with the disease duration (rho = 0.231, p = 0.04)., Conclusion: These results highlighted WL in the early stages of PD and suggested the need for adequate monitoring for patients undergoing device-aided therapy as well as oral medicine-treated patients with greater WL., (Copyright © 2024 Elsevier B.V.

- Abstract
Stress-induced β2-adrenergic receptor (β2AR) activation in B cells increases IgG secretion; however, the impact of this activation on antibody affinity and the underlying mechanisms remains unclear. In the current study, we demonstrate that stress in mice following ovalbumin (OVA) or SARS-CoV-2 RBD immunization significantly increases both serum and surface-expressed IgG binding to the immunogen, while concurrently reducing surface IgG expression and B cell clonal expansion. These effects were abolished by pharmacological β2AR blocking or when the experiments were conducted in β2AR -/- mice. In the second part of our study, we used single B cell sorting to characterize the monoclonal antibodies (mAbs) generated following β2AR activation in cultured RBD-stimulated B cells from convalescent SARS-CoV-2 donors. Ex vivo β2AR activation increased the affinities of the produced anti-RBD mAbs by 100-fold compared to mAbs produced by the same donor control cultures. Consistent with the mouse experiments, β2AR activation reduced both surface IgG levels and the frequency of expanded clones. mRNA sequencing revealed a β2AR-dependent upregulation of the PI3K pathway and B cell receptor (BCR) signaling through AKT phosphorylation, as well as an increased B cell motility. Overall, our study demonstrates that stress-mediated β2AR activation drives changes in B cells associated with BCR activation and higher affinity antibodies., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

- Abstract
Delivery of messenger RNA (mRNA) using lipid nanoparticles (LNPs) is expected to be applied to various diseases following the successful clinical use of the mRNA COVID-19 vaccines. This study aimed to evaluate the effect of the cholesterol molar percentage of mRNA-LNPs on protein expression in hepatocellular carcinoma-derived cells and in the liver after intramuscular or subcutaneous administration of mRNA-LNPs in mice. For mRNA-LNPs with cholesterol molar percentages reduced to 10 mol% and 20 mol%, we formulated neutral charge particles with a diameter of approximately 100 nm and polydispersity index (PDI) <0.25. After the intramuscular or subcutaneous administration of mRNA-LNPs with different cholesterol molar percentages in mice, protein expression in the liver decreased as the cholesterol molar percentage in mRNA-LNPs decreased from 40 mol% to 20 mol% and 10 mol%, suggesting that reducing the cholesterol molar percentage in mRNA-LNPs decreases protein expression in the liver. Furthermore, in HepG2 cells, protein expression decreased as cholesterol in mRNA-LNPs was reduced by 40 mol%, 20 mol%, and 10 mol%. These results suggest that the downregulated expression of mRNA-LNPs with low cholesterol content in the liver involves degradation in systemic circulating blood and decreased protein expression after hepatocyte distribution., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 The Authors.

- Abstract
Mass photometry (MP) is a label-free, single-molecule technique that can determine molecular mass distribution with very low sample consumption in a short time. Because of the established experimental instrument and analytical software, MP measurements may be readily obtained; thus, the application of MP is expanding, especially in the fields of bioscience and biotechnology. However, because the MP data quality is strongly focus-dependent, optical settings must be intrinsically strict. In this study, we report the importance of the critical calibration of the mass photometer, which is required for the accurate estimation of high-molecular mass samples, such as adeno-associated virus vectors. Additionally, a method for optimizing the instrument settings, including the calibration of the stage, is presented., (Copyright © 2022 American Pharmacists Association. Published by Elsevier Inc.

- Abstract
Aims: Chronic inflammation plays crucial roles in obesity-induced metabolic diseases. Protein tyrosine phosphatase receptor type O (PTPRO) is a member of the R3 subfamily of receptor-like protein tyrosine phosphatases. We previously suggested a role for PTPRO in the inactivation of the insulin receptor. The present study aimed to elucidate the involvement of PTPRO in the control of glucose and lipid metabolism as well as in obesity-induced systemic inflammation., Materials and Methods: Lipid accumulation in adipose tissue and the liver, the expression of inflammatory cytokines, and insulin resistance associated with systemic inflammation were investigated in hyper-obese Ptpro-KO mice by feeding a high-fat/high-sucrose diet (HFHSD). The effects of the administration of AKB9778, a specific inhibitor of PTPRO, to ob/ob mice and cultured 3T3-L1 preadipocyte cells were also examined., Key Findings: Ptpro was highly expressed in visceral white adipose tissue and macrophages. Ptpro-KO mice fed HFHSD were hyper-obese, but did not have ectopic fat accumulation in the liver, dysfunctional lipid and glucose homeostasis, systemic inflammation, or insulin resistance. The administration of AKB9778 reproduced "the healthy obese phenotypes" of Ptpro-KO mice in highly obese ob/ob mice. Furthermore, the inhibition of PTPRO promoted the growth of lipid droplets in adipocytes through an increase in the phosphorylation of Tyr(117) in vimentin., Significance: Healthy systemic conditions with the attenuation of inflammation in hyper-obese Ptpro-KO mice were associated with the expansion of adipose tissue and low activation of NF-κb. Therefore, PTPRO may be a promising target to ameliorate hepatic steatosis and metabolic dysfunction., Competing Interests: Declaration of competing interest The authors declare no competing interests., (Copyright © 2022 The Authors.

- Abstract
In this study, we conducted a collaborative study on the classification between silicone oil droplets and protein particles detected using the flow imaging (FI) method toward proposing a standardized classifier/model. We compared four approaches, including a classification filter composed of particle characteristic parameters, principal component analysis, decision tree, and convolutional neural network in the performance of the developed classifier/model. Finally, the points to be considered were summarized for measurement using the FI method, and for establishing the classifier/model using machine learning to differentiate silicone oil droplets and protein particles., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 The Authors.

- Abstract
Alzheimer's disease (AD) has become a major public health problem that affects the elderly population. Therapeutic compounds with curative effects are not available due to the complex pathogenesis of AD. Daphnetin, a natural coumarin derivative and inhibitor of various kinases, has anti-inflammatory and antioxidant activities. In this study, we found that daphnetin improved spatial learning and memory in an amyloid precursor protein (APP)/presenilin 1 (PS1) double-transgenic mouse model of AD. Daphnetin markedly decreased the levels of amyloid-β peptide 1-40 (Aβ
40 ) and 1-42 (Aβ42 ) in the cerebral cortex, downregulated the expressions of enzymes involved in APP processing, e.g., beta-site APP-cleaving enzyme (BACE), nicastrin and presenilin enhancer protein 2 (PEN2). We further found the reduced serum levels of inflammatory factors, including interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and chemokine (C-C motif) ligand 3 (CCL3), while daphnetin increased total antioxidant capacity (T-AOC) and superoxide dismutase (SOD) levels in the serum. Interestingly, daphnetin markedly decreased the expression of glial fibrillary acidic protein (GFAP) and the upstream regulatory molecule- phosphorylated signal transducer and activator of transcription 3 (p-STAT3) in APP/PS1 mice, and mainly inhibited the phosphorylation of STAT3 at Ser727 to decrease GFAP expression evidenced in a LPS-activated glial cell model. These results suggest that daphnetin ameliorates cognitive deficits and that Aβ deposition in APP/PS1 mice is mainly correlated with astrocyte activation and APP processing., (Copyright © 2022 Elsevier Ltd.

- Abstract
Introduction: Acute otitis media is a highly prevalent disease in children. Although guidelines in many countries recommend amoxicillin as the first-line treatment for acute otitis media, the prescribing pattern in Japan is not clear. Our objective was to clarify the amoxicillin prescriptions as first-line antibiotics for acute otitis media and factors associated with amoxicillin prescriptions. Also, changes in amoxicillin prescriptions during the study period by medical facilities were investigated., Methods: Using an administrative claims database, we included new episodes of acute otitis media prescribed antibiotics in children under seven years of age between 2014 and 2018. The proportion of amoxicillin prescription was described. Using multivariate logistic regression analysis, factors associated with amoxicillin prescription were evaluated. Rate differences were calculated to describe changes in amoxicillin prescription by medical facilities., Results: 207,213 episodes in 149,929 patients were identified. Amoxicillin prescription was 24.0% and increased over the study period (P for trend <0.001). Characteristics of medical facilities were associated with amoxicillin prescriptions, and hospitals were more likely to prescribe amoxicillin (adjusted odds ratio: 1.71, 95% confidence intervals: 1.63 to 1.79). Compared to 2014, the range of increase in amoxicillin prescription in 2018 was greater in hospitals (14.9%) and pediatric clinics (10.5%) than in otolaryngology clinics (5.9%) and other specialty clinics (6.0%)., Conclusions: During the study period, amoxicillin prescriptions had increased compared to 2014, but the proportion was still low. Clinics prescribed less amoxicillin than hospitals, and the range of increase was small. Our results suggested that some interventions focused on clinics are needed., (Copyright © 2021 Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases.

- Abstract
Background: Evidence is limited regarding the association between low-carbohydrate diet (LCD) score and mortality among Asians, a population that consumes a large amount of carbohydrates., Objective: The present study examined the association between low-carbohydrate diet (LCD) score (based on percentage of energy as carbohydrate, fat, and protein) and the risk of total and cause-specific mortality among Asians., Design: This study was a prospective cohort study in Japan with follow-up for a median of 16.9 years involving 43008 men and 50646 women aged 45-75 years. Association of LCD score, LCD score based on animal sources of protein and fat, and LCD score based on plant sources of protein and fat with risk of mortality was assessed using Cox proportional hazards model., Results: A U-shaped association was observed between LCD score and total mortality: the multivariable-adjusted hazard ratios (HRs) (95% CI) of total mortality for lowest through highest scores were 1.00, 0.95 (0.91, 1.01), 0.93 (0.88, 0.98), 0.93 (0.88, 0.98), and 1.01 (0.95, 1.07) (P-non-linearity <0.01). A similar association was found for mortality from cardiovascular disease (CVD) and heart disease. LCD score based on carbohydrate, animal protein, and animal fat also showed a U-shaped association for total mortality (P-non-linearity <0.01). In contrast, LCD score based on carbohydrate, plant protein, and plant fat was linearly associated with lower total (HR, 0.89; 95% CI: 0.83, 0.94 for highest versus lowest quintile), CVD [0.82 (0.73, 0.92)], heart disease [0.83 (0.71, 0.98)], and cerebrovascular disease [0.75 (0.62, 0.91) mortality., Conclusions: Both LCD with high animal protein and fat and high-carbohydrate diet with low animal protein and fat were associated with higher risk of mortality. Meanwhile, LCD high in plant-based sources of protein and fat was associated with a lower risk of total and CVD mortality., Competing Interests: Conflict of interest None reported., (Copyright © 2020 The Authors.

- Abstract
Background: The present study aimed to investigate the correlation between preoperative 2-deoxy-2-[
18 F]fluoro-d-glucose (18 F-FDG) PET/CT findings and short-term survival in lung cancer patients with idiopathic interstitial pneumonia (IIP)., Methods: We retrospectively reviewed the data of 425 patients who underwent lung resection for non-small cell lung cancer without preoperative radiation therapy between November 2012 and October 2017. The maximum SUV (SUVmax) in the IIP area except the lung cancer site was measured in each patient., Results: Thirty-one of the 425 patients (7.3%) showed findings of IIP in chest CT. Five of the 31 patients (16.1%) developed acute exacerbation (AE) after lung resection (AE+ group). Twenty-six of the 31 patients (83.9%) did not develop AE (AE- group). In the AE+ group,18 F-FDG SUVmax in the IIP area was significantly higher (1.9 ± 0.6 vs. 2.7 ± 0.7, p = 0.02) compared with that in the AE- group. The receiver operating characteristic analysis identified an SUVmax threshold score of 2.55 (p = 0.02) for AE. There was no 90-day mortality in the patients with SUVmax < 2.55 (n = 25). On the other hand, the 90-day mortality rate in patients with SUVmax ≥ 2.55 (n = 6) was 33.3% (2 patients)., Conclusions:18 F-FDG PET/CT may predict AE after lung resection and could be related to short-term survival in lung cancer patients with IIP. Further investigations are needed to improve the prognosis in patients with high SUVmax in the IIP area., Competing Interests: Conflict of Interest Hisashi Oishi and his co-authors have no conflicts of interest., (Copyright © 2020 The Japanese Respiratory Society.

- Abstract
To evaluate the effect of multifactorial intervention on the onset and progression of diabetic kidney disease in the patients with type 2 diabetes, we analyzed the effects of intensified multifactorial intervention by step-wise intensification of medications and life-style modifications (intensive therapy treatment targets; HbA1c under 6.2%, blood pressure under 120/75 mmHg, low-density lipoprotein cholesterol under 80 mg/dL) comparing with the guideline-based standard care (conventional therapy treatment targets: HbA1c under 6.9%, blood pressure under 130/80 mmHg, low-density lipoprotein cholesterol under 120 mg/dL) on diabetic kidney disease. A total of 2540 eligible patients in the Japan Diabetes Optimal Integrated Treatment for three major risk factors of cardiovascular diseases (J-DOIT3) cohort were randomly assigned to intensive therapy (1269) and conventional therapy (1271) and treated for a median of 8.5 years. The prespecified kidney outcome measure was a composite of progression from normoalbuminuria to microalbuminuria or progression from normoalbuminuria to macroalbuminuria or progression from microalbuminuria to macroalbuminuria, serum creatinine levels elevated by two-fold or more compared to baseline, or kidney failure. Primary analysis was carried out on the intention-to-treat population. Changes in the estimated glomerular filtration rate and albuminuria were also analyzed. A total of 438 kidney events occurred (181 in the intensive therapy group and 257 in the conventional therapy group). Intensive therapy was associated with a significant 32% reduction in kidney events compared to conventional therapy and was associated with a change in HbA1c at one year from study initiation. Thus, prespecified analysis shows that intensified multifactorial intervention significantly reduced the onset and progression of diabetic kidney disease compared to currently recommended care., (Copyright © 2020 International Society of Nephrology.

- Abstract
Background: Transit-time flow measurement (TTFM) is frequently used for intraoperative graft flow analysis during coronary artery bypass grafting (CABG). Although the TTFM results may be influenced by fractional flow reserve (FFR) of the target coronary artery as a determinant of coronary lesion-specific ischemia, the data have been limited., Methods: We retrospectively investigated the relationships between the intraoperative TTFM variables and preoperative FFR values of the target coronary arteries in 40 in situ left internal thoracic artery (LITA) grafts to the left anterior descending artery (LAD), which were revealed to be patent on postoperative computed tomographic angiography., Results: The Spearman correlation coefficients of the TTFM variables with FFR were maximum flow, -0.12 (P = .301); minimum flow (Qmin), -0.43 (P = .004); mean flow (Qm), -0.30 (P = .036); pulsatility index, 0.37 (P = .012); diastolic filling, -0.36 (P = .012); percentage insufficiency, 0.45 (P = .002); and fast Fourier transform (FFT) ratio, -0.07 (P = .329). While Min and Qm showed significant negative correlation, the pulsatility index and percentage insufficiency showed significant positive correlation with FFR., Conclusions: Most TTFM variables, including Qm, of the LITA graft to the LAD during CABG are strongly affected by preoperative FFR values. Because the FFT ratio is not influenced by FFR, FFT analysis of the TTFM may be recommend in the case of the in situ LITA graft to the LAD with moderate stenosis with a higher FFR exceeding 0.75., (Copyright © 2021 The Society of Thoracic Surgeons.

- Abstract
Na
x is a [Na+ ] sensor expressed in specific glial cells in the sensory circumventricular organs (sCVOs) in the brain. We recently demonstrated that Nax signals are involved in the control of not only salt intake but also water intake behavior. Our pharmacological experiments suggested that Nax signals led to activation of neurons bearing TRPV4 by using epoxyeicosatrienoic acids (EETs) as gliotransmitters to stimulate water intake. In the present study, we performed selective lesions of individual sCVOs in wild-type (WT) mice and the site-directed rescue of Nax expression in Nax -gene knockout (Nax -KO) mice. These experiments revealed that the Nax channel in the organum vasculosum laminae terminalis (OVLT) functions as a [Na+ ] sensor for the control of water intake behavior. Direct measurements of 5,6-EET and 8,9-EET in the OVLT demonstrated that EET levels were indeed increased two-fold by water deprivation for two days in WT, but not Nax -KO mice, indicating that EETs were Nax -dependently produced in the OVLT in response to increases in [Na+ ] in body fluids. More importantly, intracerebroventricular injection of 5,6-EET at the same level was effective to induce water intake. Double staining revealed that Nax -positive cells also expressed Cyp2c44, a cytochrome P450 epoxygenase, to generate EETs. Collectively, these results indicate that Nax -positive glial cells produce EETs to activate TRPV4-positive neurons which may stimulate water intake, in response to increases in [Na+ ] of body fluids., (Copyright © 2019 Elsevier B.V. and Japan Neuroscience Society.

- Abstract
Background: An inverse association has been shown between dietary fiber intake and several noncommunicable diseases. However, evidence of this effect remains unclear in the Asian population., Objective: We examined the association between dietary fiber intake and all-cause and cause-specific mortality, as well as the association between fiber intake from dietary sources and all-cause mortality., Methods: We conducted a large-scale population-based cohort study (Japan Public Health Center-based prospective study). A validated questionnaire with 138 food items was completed by 92,924 participants (42,754 men and 50,170 women) aged 45-74 y. Dietary fiber intake was calculated and divided into quintiles. HR and 95% CI of total and cause-specific mortality were reported., Results: During the mean follow-up of 16.8 y, 19,400 deaths were identified. In multivariable adjusted models, total, soluble, and insoluble fiber intakes were inversely associated with all-cause mortality. The HRs of total mortality in the highest quintile of total fiber intake compared with the lowest quintile were 0.77 (95% CI: 0.72, 0.82; Ptrend <0.0001) in men and 0.82 (95% CI: 0.76, 0.89; Ptrend <0.0001) in women. Increased quintiles of dietary fiber intake were significantly associated with decreased mortality due to total cardiovascular disease (CVD), respiratory disease, and injury in both men and women, whereas dietary fiber intake was inversely associated with cancer mortality in men but not women. Fiber from fruits, beans, and vegetables, but not from cereals, was inversely associated with total mortality., Conclusion: In this large-scale prospective study with a long follow-up period, dietary fiber was inversely associated with all-cause mortality. Since intakes of dietary fiber, mainly from fruits, vegetables, and beans were associated with lower all-cause mortality, these food sources may be good options for people aiming to consume more fiber., (Copyright © The Author(s) 2020.)

- Abstract
Background & Aims: Increasing evidence has suggested a protective role of vitamin D on diabetes, but epidemiologic evidence is scarce among Asian populations. Here we prospectively examined the association between serum 25-hydroxyvitamin D
3 (25[OH]D3 ) and type 2 diabetes (T2D) risk in Japanese individuals., Methods: A nested case-control study was conducted in a biomarker cohort of 4754 employees (baseline age 34-69 years) who had attended in a comprehensive health checkup and donated a blood sample. Diabetes diagnosis was based on plasma glucose, glycated hemoglobin, and self-reporting during the 5-year follow-up. Using density sampling, two controls were randomly matched to each case by sex, age, and date of checkup; 336 cases and 668 controls had serum 25(OH)D3 data. Association between serum 25[OH]D3 and the risk of T2D was assessed using conditional logistic regression analysis., Results: Serum 25(OH)D3 was significantly and inversely associated with T2D risk after adjustment for known risk factors other than BMI (OR [highest vs. lowest serum 25(OH)D3 quartile] = 0.58, 95% CI = 0.36-0.92; P for trend = 0.03). This association was somewhat attenuated after additional adjustment for BMI (OR = 0.65, 95% CI = 0.40-1.08; P for trend = 0.08). The inverse association was more evident among individuals whose blood samples were taken during the darker season (OR = 0.45; P for trend = 0.01). In the highest quartile of 25(OH)D3 , progression from prediabetes to T2D was about 37% lower than in the lowest quartile., Conclusions: Higher circulating 25(OH)D3 was associated with a lower risk of T2D, and this association was stronger among individuals whose blood was taken during the darker season and among those with prediabetes., (Copyright © 2019 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

- Abstract
Aggregation of therapeutic monoclonal antibodies has a potential risk of immunogenicity, requiring minimization of aggregate formation. We have developed a fitting formula for antibody aggregation at 40°C based on physicochemical parameters, including colloidal and conformational stabilities. An IgG1 monoclonal antibody, MAb-T, was formulated in 24 combinations of different buffer types and pH with or without sodium chloride. The fitting formula for monomer loss was successfully established by nonlinear regression analysis of the results from accelerated stability testing. Calculated monomer fraction values by the fitting formula were strongly correlated with experimental values (R
2 = 0.92). The model includes secondary virial coefficient, B22 , as the representative parameter of colloidal stability, and aggregation temperature, Tagg , representing conformational stability. Then, we examined charge state, conformational flexibility, and thermal unfolding profile of MAb-T to clarify the molecular basis for the different aggregation propensities in sodium acetate buffer and in sodium citrate buffer at the same pH and buffer concentration. We concluded that the accumulation of citrate anions on the surface of MAb-T is the primary source of the less colloidal and conformational stabilities, resulting in the higher aggregation propensity in sodium citrate buffer., (Copyright © 2020 American Pharmacists Association®.

- Abstract
Background: Pulmonary endarterectomy (PEA) for chronic thromboembolic pulmonary hypertension (CTEPH) is technically demanding. We tried to identify the predictors for short- and long-term outcomes after PEA for CTEPH with aggressive use of pulmonary vasodilators, including epoprostenol sodium., Methods: From 2005 to 2013, 122 CTEPH patients, whose preoperative mean pulmonary artery pressure (mPAP) was 47 ± 10 mm Hg and pulmonary vascular resistance was 847 ± 373 dynes/s/cm
5 , underwent PEA with hypothermic circulatory arrest. Before PEA, all patients underwent pulmonary vasodilator therapy, including epoprostenol sodium of 2 to 6 ng/kg/min. We collected the perioperative and follow-up data retrospectively to identify the predictors for early and late outcomes after PEA., Results: In-hospital mortality was 7.4% (n = 9). Predictors for in-hospital death were age older than 65 years and New York Heart Association Functional Classification IV. Among the 113 PEA survivors, the mPAP and pulmonary vascular resistance significantly decreased. After the median follow-up of 6.8 years, the overall survival rates were 91.8%, 89.2%, 89.2%, 89.2%, and 86.1%, and the cardiac events-free rates were 100%, 98.1%, 95.8%, 85.5%, and 49.0%, at 1, 3, 5, 7, and 10 years, respectively, in the Kaplan-Meier model. A multivariate Cox proportional hazard model identified postoperative mPAP exceeding 30 mm Hg as the only predictor for late cardiac events., Conclusions: Early and late outcomes of PEA for CTEPH with perioperative aggressive pulmonary vasodilator treatment seem satisfactory. However, residual pulmonary hypertension remains challenging to achieve further improvement of late outcomes., (Copyright © 2019 The Society of Thoracic Surgeons. Published by Elsevier Inc.

- Abstract
Background: Few studies have assessed associations of non-enzymatic antioxidant capacity (NEAC) in the overall diet with all-cause or specific mortality, and their results have been inconsistent., Objectives: The present study investigated the association between dietary NEAC and all-cause or cause-specific mortality., Methods: The study was a large-scale population-based prospective cohort study in Japan consisting of 42,520 men and 50,207 women aged 44-76 y, who had no history of cancer, stroke, ischemic heart disease, or chronic liver disease. We evaluated FFQ-based dietary NEAC with use of published databases in which the NEACs of individual foods were analyzed by ferric reducing antioxidant power (FRAP) and oxygen radical absorbance capacity (ORAC) assays. Dietary NEAC was calculated by multiplying the estimated NEAC with the consumed amount and summing up those values for all foods, and was categorized in quartiles. We identified death and cause of death with use of residential registry and death certificates. HRs and 95% Cls for death from the second survey, which was conducted from April 1995 to December 2014 were estimated with Cox proportional hazards regression analysis., Results: After 1,498,308 person-years of follow-up, 12,978 total deaths occurred. The multivariable-adjusted HRs (95% Cls) for all-cause mortality for the highest compared with the lowest quartile of FRAP and ORAC were 0.85 (0.80, 0.89) and 0.84 (0.79, 0.89), respectively. Dietary NEACs were inversely associated with mortality from cardiovascular disease (CVD), but not from cancer. The multivariable-adjusted HRs (95% Cls) for CVD for the highest compared with the lowest quartile of FRAP and ORAC were 0.83 (0.75, 0.92) and 0.79 (0.70, 0.89), respectively., Conclusions: Higher dietary NEACs from FRAP and ORAC were associated with lower risk of all-cause mortality and mortality from CVD in Japanese adults., (Copyright © American Society for Nutrition 2019.)

- Abstract
A number of biopharmaceuticals are available as lyophilized formulations along with a prefilled syringe (PFS) containing water for injection (WFI). Submicron- and micron-size droplets of lubricating silicone oil (SO) applied to the inner surface of the PFS barrel might migrate into the WFI, to which protein pharmaceuticals can adsorb, potentially inducing an immune response. In the present study, we subjected siliconized cyclo-olefin polymer PFSs filled with WFI to dropping stress to simulate actual shipping conditions as well as evaluated the risk associated with the released SO droplets. The results confirmed the undesirable effects of SO on therapeutic proteins, including adsorption to SO droplets and increased secretion of several innate cytokines from human peripheral blood mononuclear cells of a small donor panel. Assessment of immunogenicity in vivo using BALB/c mice revealed a slight increase in the plasma concentrations of antidrug antibodies over 21 days in response to SO-containing antibody samples compared to the absence of SO. These results indicate that SO droplets form complexes with pharmaceutical proteins that can potentially invoke early- and late-stage immune responses. Therefore, the use of SO-free cyclo-olefin polymer PFSs as primary containers for WFI could contribute to the enhanced safety of reconstituted biopharmaceuticals., (Copyright © 2019 The Authors.

- Abstract
Antibody aggregates are a potential risk for immunogenicity; therefore, rational approaches to improve associated aggregation properties need to be developed. Here, we report the amino acid region responsible for aggregation initiation. Two types of therapeutic IgG1 antibody monomer samples were prepared: IgG1 mAb40-3M stored at 40°C for 3 months, which existed in monodisperse state, and the monomer mAb65-5m, which was dissociated from small soluble aggregates by heating at 65°C for 5 min. Hydrogen deuterium exchange mass spectrometry of mAb40-3M identified 2 sites in the Fc region (site 1, F239-M256; site 2, S428-G450) with increased exchange rates. Site 1 includes a region reported as being susceptible to structural change induced by stress. Exposure of site 1 was undetected after 2 months of storage at 40°C but was subsequently detectable after 3 months. As site 2 is spatially close to site 1, the structural change of site 1 could propagate site 2. Besides these 2 regions, hydrogen deuterium exchange mass spectrometry of mAb65-5m identified an exposure of I257-W281 in Fc (site 3), within which a peptide sequence with high aggregation tendency was discovered. We thus concluded that exposure of site 3 is a trigger for the association of a partially denatured antibody., (Copyright © 2019 American Pharmacists Association®. Published by Elsevier Inc.

- Abstract
Background & Aims: Cruciferous vegetables contain isothiocyanates, which effectively reduce inflammation and oxidative stress related to chronic diseases, inhibit the bioactivation of procarcinogens, and enhance the excretion of carcinogens. However, at present, no large cohort studies have investigated the effect of cruciferous vegetable on mortality. We aimed to examine the association between cruciferous vegetable intake and all-cause mortality, namely cancer, heart disease, cerebrovascular disease, and injuries, in a large cohort study conducted between 1990 and 1993, in Japan., Methods: The analysis included 88,184 participants (age: 45-74 years) with no history of cancer, myocardial infarction, and stroke. Participants were tracked for a median of 16.9 years, during which 15,349 deaths were occurred. The association between cruciferous vegetable intake and risk of all-cause and cause-specific mortality was determined by Cox proportional hazard regression analysis to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs), after adjustment for potential confounding factors., Results: An inverse association was found between cruciferous vegetable intake and total mortality in both gender. HRs (95% CI) for all-cause mortality in the highest compared to the lowest quintile were 0.86 (0.80, 0.93) for men (P = 0.0002 for trend) and 0.89 (0.81, 0.98) for women (P = 0.03 for trend). Cruciferous vegetable intake was associated with lower cancer mortality in men, as well as with heart disease-, cerebrovascular disease-, and injury-related mortality in women., Conclusions: This prospective study suggests that a higher cruciferous vegetables intake is associated with reduced risk of all-cause mortality., (Copyright © 2018 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

- Abstract
Background: Cardio-facio-cutaneous syndrome (CFCS) is a rare genetic disorder characterized by cardiovascular anomalies, dysmorphic faces, ectodermal abnormalities and developmental delays. Mutations in BRAF and other RAS-MAPK pathway-associated genes are commonly identified in patients with CFCS. While this molecular pathway is known to be associated with neuro-inflammatory conditions, only one case with CFCS has been reported thus far to develop acute encephalopathy in childhood., Case Report: A 3-year-old boy with dysmorphic features and mild psychomotor delay developed acute encephalopathy. After a 45-min long, generalized seizure, the magnetic resonance imaging revealed that the restricted diffusion signals spread to the bilateral subcortical white matters on day 1 of illness. Despite the 14 days of intensive care, the acute symptoms of encephalopathy left him intractable epilepsy and severe neurocognitive impairments. The whole-exome sequencing analysis identified a de novo heterozygous mutation of BRAF (NM_004333:p.Thr241Met) in this case., Conclusion: The present case suggests that the hyperactive condition of ERK signals might augment the development of acute encephalopathy and post-encephalopathic epilepsy in childhood., (Copyright © 2018 The Japanese Society of Child Neurology.

- Abstract
Bone mass is determined by coordinated acts of osteoblasts and osteoclasts, which control bone formation and resorption, respectively. Osteoclasts are multinucleated, macrophage/monocyte lineage cells from bone marrow. The Dok-family adaptors Dok-1, Dok-2 and Dok-3 are expressed in the macrophage/monocyte lineage and negatively regulate many signaling pathways, implying roles in osteoclastogenesis. Indeed, mice lacking Dok-1 and Dok-2, the closest homologues with redundant functions, develop osteopenia with increased osteoclast counts compared to the wild-type controls. Here, we demonstrate that Dok-3 knockout (KO) mice also develop osteopenia. However, Dok-3 KO, but not Dok-1/-2 double-KO (DKO), mice develop larger osteoclasts within the normal cell-count range, suggesting a distinctive role for Dok-3. Indeed, Dok-3 KO, but not Dok-1/-2 DKO, bone marrow-derived cells (BMDCs) generated larger osteoclasts with more nuclei due to augmented cell-to-cell fusion in vitro. In addition, while Dok-1/-2 DKO BMDCs generated more osteoclasts, Dok-1/-2/-3 triple-KO (TKO) BMDCs generated osteoclasts increased in both number and size. Furthermore, Dok-1/-2/-3 TKO mice showed the combined effects of Dok-3 and Dok-1/-2 deficiency: severe osteopenia with more and larger osteoclasts. Together, our findings demonstrate that Dok-3 and Dok-1/-2 play distinctive but cooperative roles in osteoclastogenesis and protect mice from osteopenia, providing physiological and pathophysiological insight into bone homeostasis., (Copyright © 2018 Elsevier Inc.

- Abstract
Background: The dystroglycan complex consists of two subunits: extracellular α-dystroglycan and membrane-spanning β-dystroglycan, which provide a tight link between the extracellular matrix and the intracellular cytoskeleton. Previous studies showed that 43 kDa β-dystroglycan is proteolytically cleaved into the 30 kDa fragment by matrix metalloproteinases (MMPs) in various non-muscle tissues, whereas it is protected from cleavage in muscles by the sarcoglycan complex which resides close to the dystroglycan complex. It is noteworthy that cleaved β-dystroglycan is detected in muscles from patients with sarcoglycanopathy, sarcoglycan-deficient muscular dystrophy. In vitro assays using protease inhibitors suggest that both MMP-2 and MMP-9 contribute to the cleavage of β-dystroglycan. However, this has remained uninvestigated in vivo., Methods: We generated triple-knockout (TKO) mice targeting MMP-2, MMP-9 and γ-sarcoglycan to examine the status of β-dystroglycan cleavage in the absence of the candidate matrix metalloproteinases in sarcoglycan-deficient muscles., Results: Unexpectedly, β-dystroglycan was cleaved in muscles from TKO mice. Muscle pathology was not ameliorated but worsened in TKO mice compared with γ-sarcoglycan single-knockout mice. The gene expression of MMP-14 was up-regulated in TKO mice as well as in γ-sarcoglycan knockout mice. In vitro assay showed MMP-14 is capable to cleave β-dystroglycan., Conclusions: Double-targeting of MMP-2 and MMP-9 cannot prevent cleavage of β-dystroglycan in sarcoglycanopathy. Thus, matrix metalloproteinases contributing to β-dystroglycan cleavage are redundant, and MMP-14 could participate in the pathogenesis of sarcoglycanopathy., (Copyright © 2017 Elsevier Inc.

- Abstract
Bronchiolitis obliterans after lung transplantation is a major cause of postoperative mortality in which T cell-mediated immunity is known to play an important role. However, the exact contribution of natural killer (NK) cells, which have functions similar to CD8
+ T cells, has not been defined. Here, we assessed the role of NK cells in murine bronchiolitis obliterans through heterotopic tracheal transplantations and found a greater percentage of NK cells in allografts than in isografts. Depletion of NK cells using an anti-NK1.1 antibody attenuated bronchiolitis obliterans in transplant recipients compared with controls. In terms of NK cell effector functions, an improvement in bronchiolitis obliterans was observed in perforin-KO recipient mice compared to wild type (WT). Furthermore, we found upregulation of NKG2D-ligand in allografts and demonstrated the significance of this using grafts expressing Rae-1, a murine NKG2D-ligand, which induced severe bronchiolitis obliterans in WT and Rag-1 KO recipients. This effect was ameliorated by injection of anti-NKG2D blocking antibody. Together, these results suggest that cytotoxicity resulting from activation of NK cells through NKG2D leads to the development of murine bronchiolitis obliterans., (© 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.)- Published

- Abstract
Background: The association between the circulating fatty acid (FA) composition and type 2 diabetes (T2D) has been reported in Western populations, but evidence is scarce among Asian populations, including Japanese, who consume large amounts of fish. Objective: The objective of the present study was to prospectively examine the association between circulating concentrations of individual FAs and T2D incidence among Japanese adults. Methods: We conducted a nested case-control study in a cohort of 4754 employees, aged 34-69 y, who attended a comprehensive health checkup in 2008-2009 and donated blood samples for the Hitachi Health Study. During 5 y of follow-up, diabetes was identified on the basis of plasma glucose, glycated hemoglobin, and self-report. Two controls matched to each case by sex, age, and date of checkup were randomly chosen by using density sampling, resulting in 336 cases and 678 controls with FA measurements. GC was used to measure the FA composition in serum phospholipids. Cox proportional hazards regression was used to estimate the HRs and 95% CIs after adjusting for potential confounders. We examined the association of T2D risk with 25 different individual and combinations of FAs. Results: T2D risk was positively associated with serum dihomo-γ-linoleic acid concentration (highest compared with the lowest quartile-HR: 1.49; 95% CI: 1.04, 2.11; P- trend = 0.02) and inversely associated with Δ5-desaturase activity (highest compared with the lowest quartile-HR: 0.72; 95% CI: 0.52, 0.99; P- trend = 0.02), independent of body mass index (BMI). There were also inverse associations between T2D risk with serum total n-6 (ω-6) polyunsaturated fatty acids (PUFAs), linoleic acid, and cis -vaccenic acid, but these were attenuated and became nonsignificant after adjustment for BMI. Serum n-3 (ω-3) PUFAs and saturated fatty acids (SFAs) were not associated with T2D risk. Conclusions: T2D risk was associated with circulating concentrations of the n-6 PUFA dihomo-γ-linoleic acid and Δ5-desaturase activity but not with n-3 PUFA or SFA concentrations in Japanese adults., Competing Interests: Author disclosures: SA, K Kurotani, MS, Takuya Hayashi, K Kuwahara, YM, TN, MK, T Honda, SY, Takeshi Hayashi, MN, and TM, no conflicts of interest., (© 2017 American Society for Nutrition.)

- Abstract
Background: Diet-induced metabolic acidosis has been linked to cardiometabolic abnormalities including hypertension and type 2 diabetes. However, there are limited data on its association with other chronic diseases and mortality. Objective: The present study aimed to examine the association between dietary acid load and total and cause-specific mortality. Design: This study was a large-scale, population-based, prospective cohort study in Japan involving 42,736 men and 49,742 women, aged 45-75 y, who had no history of cancer, stroke, ischemic heart disease (IHD), or chronic liver disease at baseline. Dietary intake was assessed by using a validated 147-item food-frequency questionnaire. Potential renal acid load (PRAL) and net endogenous acid production (NEAP) scores were derived from nutrient intake. Death and cause of death were identified by using the residential registry and death certificates. Cox proportional hazards regression was used to estimate HRs and 95% CIs for total and cause-specific mortality with adjustment for potential confounding variables. Results: During a median follow-up of 16.9 y, 12,993 total deaths occurred. A higher PRAL score was associated with higher total mortality: the multivariable-adjusted HR for total mortality for the highest compared with the lowest quartiles of PRAL scores was 1.13 (95% CI: 1.07, 1.18; P -trend < 0.001). This score was positively associated with mortality from cardiovascular disease (CVD) and particularly from IHD; the HRs (95% CIs) for the highest compared with the lowest quartile of PRAL score were 1.16 (1.06, 1.28) and 1.16 (1.02, 1.33) for CVD and IHD mortality, respectively. There was no association between PRAL score and cancer mortality. Similar associations were observed between NEAP score and total and cause-specific mortality. Conclusion: A high dietary acid load score was associated with a higher risk of total mortality and mortality from CVD, particularly from IHD, in Japanese adults., (© 2017 American Society for Nutrition.)

- Abstract
In solitary fibrous tumors (SFTs) of the pleura, malignant SFTs are uncommon. Although SFTs are known to cause paraneoplastic syndromes through the production of insulin-like growth factor, to the best of our knowledge, the production of beta-human chorionic gonadotropin (β-hCG) has been reported only in 1 case involving a patient with a benign SFT. We herein report the first case of the elevation of β-hCG serum levels associated with a malignant SFT in which the β-hCG serum level became a useful indicator of recurrence after the complete resection of the primary mediastinal lesion., (Copyright © 2016 The Society of Thoracic Surgeons.

- Abstract
Background: Vascular endothelial growth factor (VEGF) signaling is an important pathway in the development of diabetic retinopathy (DR). A recent report showed that leukocyte cell-derived chemotaxin 2 (LECT2) suppresses the VEGF signaling in endothelial cells. However, the clinical relevance of LECT2 in DR is unknown. This study aimed to investigate serum LECT2 levels and the presence of DR., Methods: The study included 230 people with type 2 diabetes mellitus (DM), 95 with DR and 135 without DR. Serum LECT2 levels were measured using an enzyme-linked immunosorbent assay. Data were evaluated using Spearman's rank correlation, univariate and multivariate logistic regression., Results: Serum LECT2 levels were significantly lower in participants with DM having DR than in those not having DR (35.6±14.9ng/ml vs. 44.5±17.6ng/ml, P<0.001). Spearman's rank correlation analysis revealed a significant association between serum LECT2 levels and the presence of DR (P<0.001). Multiple regression analysis revealed that serum LECT2 levels were independently related to DR (P<0.001)., Conclusions: These findings indicated that serum LECT2 level is negatively associated with the presence of DR and suggest that low circulating LECT2 level is a risk factor for DR., (Copyright © 2016 The Authors.

- Abstract
The brain monitors conditions of body fluids and levels of circulating neuroactive factors to maintain the systemic homeostasis. Unlike most regions in the brain, circumventricular organs (CVOs) lack the blood-brain barrier, and serve as the sensing center. Among the CVOs, the subfornical organ (SFO) is the sensing site of Na
+ levels in body fluids to control water and salt intake. The SFO harbors neuronal cell bodies with a variety of hormone receptors and innervates many brain loci. In addition, the SFO harbors specialized glial cells (astrocytes and ependymal cells) expressing Nax , a Na+ -level-sensitive sodium channel. These glial cells wrap a specific population of neurons with their processes, and control the firing activities of the neurons by gliotransmitters, such as lactate and epoxyeicosatrienoic acids (EETs), relevant to water/salt-intake behaviors. Recent advances in the understanding of physiological functions of the SFO are reviewed herein with a focus on the Na+ -sensing mechanism by Nax ., (Copyright © 2016 Elsevier Ireland Ltd and Japan Neuroscience Society.

- Abstract
Norovirus is detected from shellfish and environmental water more frequently in winter than in other seasons. However, there is no report regarding its viability in actual seawater in situ. We investigated the viability of murine norovirus strain 1 (MNV-1), a surrogate for human norovirus, in 2 types of aquatic locations, a seawater pool carrying oceanic water and inner bay carrying brackish water. Sterilized seawater was inoculated with MNV-1 and enclosed in dialysis tubes, which were placed at the 2 locations. MNV-1 exhibited higher level of viability in brackish than in oceanic water. Factors that influenced the viability of MNV-1 included salt concentration as well as temperature of the seawater. Therefore, based on our findings, coastal brackish water that is routinely used for harvesting or cleaning seafood at fishing ports may promote the viability of norovirus., (Copyright © 2016 Elsevier Ltd.

- Abstract
Background: Renal dysfunction is a common comorbidity in acute heart failure (AHF) patients. The prognostic significance of early treatment with tolvaptan in AHF patients complicated with renal dysfunction has not been elucidated., Methods: Post hoc analysis was performed on a randomized clinical study for prespecified prognostic endpoints and prespecified subgroups. 217 AHF patients with renal dysfunction (eGFR 15 to 60mL/min/1.73m(2)) were randomized within 6h from hospitalization to either tolvaptan treatment for 2days or conventional treatment. The primary outcome was the combined endpoint of all-cause death and HF readmission., Results: During follow-up (636days, median) 99 patients experienced combined endpoint and 53 patients died. There was no significant difference in event-free survival rate for either the combined events (Log-rank: P=0.197) or all-cause death (Log-rank: P=0.894) between tolvaptan and conventional groups. In prespecified subgroup analysis, in patients whose BUN/creatinine ratio was above the median (>20), tolvaptan significantly reduced the risk of combined events (HR: 0.52, 95% CI: 0.30-0.91, P=0.021) with a significant interaction (P value for interaction=0.045). Likewise, in patients whose eGFR was 30mL/min/1.73m(2) or above, tolvaptan reduced the risk of combined events (HR: 0.54, 95% CI: 0.32-0.90, P=0.017) with a significant interaction (P value for interaction=0.015)., Conclusion: Short-term use of tolvaptan in acute-phase in AHF with renal dysfunction showed a neutral effect on prognosis. Patients with relatively preserved renal function and relatively high BUN/creatinine ratios are potentially favorable subgroups for treatment with tolvaptan., (Copyright © 2016 Elsevier Ireland Ltd.

- Abstract
Estrogen deficiency-induced obesity has a high risk of visceral fat accumulation and body weight gain. It is also associated with many adverse health conditions. Taheebo extract from Tabebuia avellanedae has been recognized as playing several biological and pharmacological roles. Therefore, we investigated whether the intake of n-BuOH extract of Taheebo shows anti-obesity effect in ovariectomized (OVX) mice. After 16 weeks of feeding, the mice administrated with 0.5% n-BuOH extract of Taheebo showed significantly decreased body weight compared with that of the control mice, and the fat mass also showed a significant decrease. In 3T3-L1 cells, supplementation with n-BuOH extract of Taheebo significantly reduced the triglyceride (TG) levels. Furthermore, bioassay-guided purification of the n-BuOH extract based on the TG levels in 3T3-L1 cells led to the isolation of compound 2 (1-dehydroxy-3,4-dihydroaucubigenin). These results suggested that the anti-obesity effect of Taheebo extract is due to its capability in preventing the accumulation of adipocyte in mice. Taheebo extract might be a promising functional food resources capable of protecting against OVX-induced obesity., (Copyright © 2016 Elsevier Inc. All rights reserved.)

- Abstract
One of the β-1,3-glucans, laminarin, has been widely used as a substrate for enzymes including endo-1,3-β-glucanase. To obtain quantitative information about the molecular interaction between laminarin and endo-1,3-β-glucanase, the structural properties of laminarin should be determined. The results from pioneering work using analytical ultracentrifugation for carbohydrate analysis showed that laminarin from Laminaria digitata predominantly exists as a single-chain species with approximately 5% of triple-helical species. Differential scanning calorimetry experiments did not show a peak assignable to the transition from triple-helix to single-chain, supporting the notion that a large proportion of laminarin is the single-chain species. The interaction of laminarin with an inactive variant of endo-1,3-β-glucanase from Cellulosimicrobium cellulans, E119A, was quantitatively analyzed using isothermal titration calorimetry. The binding was enthalpically driven and the binding affinity was approximately 10(6) M(-1). The results from binding stoichiometric analysis indicated that on average, E119A binds to laminarin in a 2:1 ratio. This seems to be reasonable, because laminarin mainly exists as a monomer, the apparent molecular mass of laminarin is 3.6 kDa, and E119A would have substrate-binding subsites corresponding to 6 glucose units. The analytical ultracentrifugation experiments could detect different complex species of laminarin and endo-1,3-β-glucanase., (Copyright © 2016 Elsevier Ltd. All rights reserved.)

- Abstract
Background: Diet-induced metabolic acidosis has been linked to cardiometabolic abnormalities in Westerners, but the evidence on this issue is scarce in Asians., Objective: The present study prospectively examined the association between dietary acid load and type 2 diabetes (T2D) in Japanese adults., Methods: Study participants were 27,809 men and 36,851 women, aged 45-75 y, who completed a dietary questionnaire of the second survey of the Japan Public Health Center-based Prospective Study and had no previous history of T2D. Dietary intake was assessed by using a validated 147-item food-frequency questionnaire. Potential renal acid load (PRAL) and net endogenous acid production (NEAP) scores were derived from the nutrient intake. A multilevel logistic regression model was used to estimate ORs and 95% CIs of self-reported, physician-diagnosed T2D over 5 y, with adjustment for potential confounding variables., Results: A total of 1191 cases of newly diagnosed T2D were reported. PRAL score was positively associated with T2D in men; the multivariable-adjusted ORs (95% CIs) for the lowest through the highest quartiles of PRAL were 1.00, 1.09 (0.87, 1.36), 1.10 (0.88, 1.37), and 1.25 (1.01, 1.55) (P-trend = 0.047). Further adjustment for dietary intake strengthened the association. NEAP score was not associated with the risk of T2D (P-trend = 0.20). In stratified analyses, the positive association between PRAL and T2D was confined to younger men (age <50 y; P-trend = 0.046). There was no association between dietary acid load score and T2D in women., Conclusion: A high dietary acid load score is associated with an increased risk of T2D in Japanese men., (© 2016 American Society for Nutrition.)

- Abstract
Pulmonary arterial hypertension after arterial switch operation for transposition of the great arteries is an infrequent but life-threatening complication. We report successful lung transplantation in a case of pulmonary hypertension after arterial switch operation. Cardiopulmonary bypass outflow was established through the right subclavian and femoral arteries because of the previous arterial switch operation. Abnormal anatomy and severe pleural and pericardial adhesions as a result of previous operations resulted in prolonged graft ischemic and operation times. Despite delayed left heart adaptation and primary graft dysfunction requiring prolonged extracorporeal membrane oxygenation, the recipient was eventually discharged without activity limitations., (Copyright © 2015 The Society of Thoracic Surgeons.

- Abstract
Reelin has recently attracted attention because of its connection to several neuropsychiatric diseases. We previously reported the finding that prior transplantation of GABAergic neuron precursor cells into the medial prefrontal cortex (mPFC) of mice significantly prevented the induction of cognitive and sensory-motor gating deficits induced by phencyclidine (PCP). The majority of the precursor cells transplanted into the mPFC of the recipient mice differentiated into members of a somatostatin/Reelin-expressing class of GABAergic interneurons. These findings raised the possibility that Reelin secreted by the transplanted cells plays an important role in preventing the deficits induced by PCP. In this study, we investigated whether Reelin itself has a preventive effect on PCP-induced behavioral phenotypes by injecting conditioned medium containing Reelin into the lateral ventricle of the brains of 6- to 7-week-old male mice before administrating PCP. Behavioral analyses showed that the prior Reelin injection had a preventive effect against induction of the cognitive and sensory-motor gating deficits associated with PCP. Moreover, one of the types of Reelin receptor was found to be expressed by neurons in the mPFC. The results of this study point to the Reelin signaling pathway as a candidate target for the pharmacologic treatment of neuropsychiatric diseases., (Copyright © 2015 Elsevier Ireland Ltd and the Japan Neuroscience Society.

- Abstract
Purpose: We examined the association between green tea consumption and mortality due to all causes, cancer, heart disease, cerebrovascular disease, respiratory disease, injuries, and other causes of death in a large-scale population-based cohort study in Japan., Methods: We studied 90,914 Japanese (aged between 40 and 69 years) recruited between 1990 and 1994. After 18.7 years of follow-up, 12,874 deaths were reported. The association between green tea consumption and risk of all causes and major causes of mortality was assessed using the Cox proportional hazards regression model with adjustment for potential confounders., Results: Hazard ratios for all-cause mortality among men who consumed green tea compared with those who drank less than 1 cup/day were 0.96 (0.89-1.03) for 1-2 cups/day, 0.88 (0.82-0.95) for 3-4 cups/day, and 0.87 (0.81-0.94) for more than 5 cups/day (P for trend <.001). Corresponding hazard ratios for women were 0.90 (0.81-1.00), 0.87 (0.79-0.96), and 0.83 (0.75-0.91; P for trend <.001). Green tea was inversely associated with mortality from heart disease in both men and women and mortality from cerebrovascular disease and respiratory disease in men. No association was found between green tea and total cancer mortality., Conclusions: This prospective study suggests that the consumption of green tea may reduce the risk of all-cause mortality and the three leading causes of death in Japan., (Copyright © 2015 Elsevier Inc.

- Abstract
Background: Despite the rising consumption of coffee worldwide, few prospective cohort studies assessed the association of coffee intake with mortality including total and major causes of death., Objective: We aimed to investigate the association between habitual coffee drinking and mortality from all causes, cancer, heart disease, cerebrovascular disease, respiratory disease, injuries, and other causes of death in a large-scale, population-based cohort study in Japan., Design: We studied 90,914 Japanese persons aged between 40 and 69 y without a history of cancer, cerebrovascular disease, or ischemic heart disease at the time of the baseline study. Subjects were followed up for an average of 18.7 y, during which 12,874 total deaths were reported. The association between coffee intake and risk of total and cause-specific mortality was assessed by using a Cox proportional hazards regression model with adjustment for potential confounders., Results: We showed an inverse association between coffee intake and total mortality in both men and women. HRs (95% CIs) for total death in subjects who consumed coffee compared with those who never drank coffee were 0.91 (0.86-0.95) for <1 cup/d, 0.85 (0.81-0.90) for 1-2 cups/d, 0.76 (0.70-0.83) for 3-4 cups/d, and 0.85 (0.75-0.98) for >5 cups/d (P-trend < 0.001). Coffee was inversely associated with mortality from heart disease, cerebrovascular disease, and respiratory disease., Conclusion: With this prospective study, we suggest that the habitual intake of coffee is associated with lower risk of total mortality and 3 leading causes of death in Japan., (© 2015 American Society for Nutrition.)

- Abstract
Background/objectives: HMG-CoA reductase inhibitors (statins) reduce ischemic heart disease (IHD) in middle-aged diabetic individuals, and LDL-cholesterol (LDL-C) is a risk factor. However, their preventive effects on cerebrovascular attack (CVA) have not been identified in elderly, especially in elderly ≥ 75 years (late elderly), who account for approximately 30% of diabetic individuals in Japan. Randomized controlled studies of statins for late elderly are difficult to carry out, because many co-morbidities in elderly disrupt randomized controlled conditions., Methods: We performed a prospective cohort study (Japan Cholesterol and Diabetes Mellitus Study) with 5.5 years of follow-up since 2004. A total of 4014 type 2 diabetic patients without previous IHD or CVA (n=1936 women; age = 67.4 ± 9.5 years; ≥ 75 years: n = 1016) were enrolled, while 405 patients were registered as sub-cohort patients. We recorded detailed information on medications and laboratory data after every change in medication in patients of sub-cohort and suffered from IHD or CVA. We subdivided statin-users into prevalent, new and non-users., Results: A total of 104 CVAs occurred during 5.5-years. Plasma HDL-C level was inversely correlated with CVA in patients ≥ 65 years. In case-control study, among patients who were not prescribed statins, CVA increased in age-dependent manner. CVA incidence was lower in prevalent and new statin-users than in non-users (hazard ratio [HR]:0.46, 0.523), especially in late elderly (HR: 0.51, 0.21). Statins reduced CVAs mainly due to a direct effect and partially due to the effects of HDL-C and glucose metabolism. No significant differences were observed between statins., Conclusion: Statins prevented CVA in middle-aged, elderly and late elderly diabetic patients via a direct effect. This study is the first to demonstrate the usefulness of observational studies for statistically analyzing agents' effects on late elderly., (Copyright © 2014 Elsevier Ireland Ltd.

- Abstract
A 14-year-old female patient underwent right single living-donor lobar lung transplantation for bronchiolitis obliterans after bone marrow transplantation. The patient experienced a complication with severe hypoxemia requiring venovenous extracorporeal membrane oxygenation, which appeared to result from significant ventilation-perfusion mismatch caused by preferential ventilation of the transplanted lobe and relatively preserved perfusion to the native lung. On day 2, we performed left pulmonary artery banding, which significantly improved oxygenation leading to weaning from extracorporeal membrane oxygenation. Our experience indicates that contralateral pulmonary artery banding may be a feasible option to rescue patients from hypoxemia resulting from ventilation-perfusion mismatch after single living-donor lobar lung transplantation., (Copyright © 2014 The Society of Thoracic Surgeons.

- Abstract
An automatic polymerase chain reaction (PCR) product detection system for food safety monitoring using zinc finger (ZF) protein fused to luciferase was developed. ZF protein fused to luciferase specifically binds to target double stranded DNA sequence and has luciferase enzymatic activity. Therefore, PCR products that comprise ZF protein recognition sequence can be detected by measuring the luciferase activity of the fusion protein. We previously reported that PCR products from Legionella pneumophila and Escherichia coli (E. coli) O157 genomic DNA were detected by Zif268, a natural ZF protein, fused to luciferase. In this study, Zif268-luciferase was applied to detect the presence of Salmonella and coliforms. Moreover, an artificial zinc finger protein (B2) fused to luciferase was constructed for a Norovirus detection system. In the luciferase activity detection assay, several bound/free separation process is required. Therefore, an analyzer that automatically performed the bound/free separation process was developed to detect PCR products using the ZF-luciferase fusion protein. By means of the automatic analyzer with ZF-luciferase fusion protein, target pathogenic genomes were specifically detected in the presence of other pathogenic genomes. Moreover, we succeeded in the detection of 10 copies of E. coli BL21 without extraction of genomic DNA by the automatic analyzer and E. coli was detected with a logarithmic dependency in the range of 1.0×10 to 1.0×10(6) copies., (Copyright © 2013 Elsevier B.V.

- Abstract
Introduction: In the treatment of avulsion fractures of the posterior calcaneal tuberosity, open reduction and internal fixation are prone to several complications. We describe a new treatment using an Ilizarov external fixator, which can minimise the complications and achieve sufficient stability of the displaced fragment., Case Presentation: A 55-year-old woman sustained an avulsion fracture of the calcaneus. Examination revealed the development of bruising with extremely taut skin over the posterior prominence of the displaced bone. Radiographs demonstrated grossly proximal displacement of the tuberosity fragment. Surgery was exclusively percutaneous using an Ilizarov external fixator. The displaced fragment was adequately reduced and stabilised. Progressive weight bearing in the equinus position was initiated at the third week after surgery and the external fixator was removed at the seventh week. There was no skin necrosis or loss of reduction while the fixator was maintained. Postoperative follow-up for 2 years revealed full recovery., Discussion: Major postoperative complications after conventional open reduction and internal fixation include skin necrosis, skin irritation by metal implants and re-displacement of the reduced fragment. Our method of using an external fixator may decrease the incidence of these three complications. Skin incision and the risk of skin necrosis are inevitable during internal fixation. On the other hand, the use of an external fixator reduces or eliminates skin necrosis, as it is applied percutaneously for reduction and stabilisation of the fragment. External fixation is mostly recommended in cases of poor vascularity or bruising. In addition, skin irritation can be avoided upon removal of the external fixator. Re-displacement occurs occasionally as a serious complication in lag screw fixation, particularly in cases with poor purchase of the osteoporotic bone. Tension band wiring and application of an Ilizarov external fixator in avulsion fractures of the calcaneus can neutralise tension on the Achilles tendon during the healing process. Thus, both these methods are believed to provide sufficient mechanical stability to fix the fragment., Conclusion: This new method, involving application of an Ilizarov external fixator, is recommended when the avulsion fragment is large enough to accommodate Ilizarov wires, especially in cases of circulatory problems or bruising., (Copyright © 2013 Elsevier Ltd.

- Abstract
Microglia, which constitute the resident macrophages of the central nervous system (CNS), are generally considered as the primary immune cells in the brain and spinal cord. Microglial cells respond to various factors which are produced following nerve injury of multiple aetiologies and contribute to the development of neuronal disease. Chemokine (C-C motif) ligand 1 (CCL-1), a well-characterized chemokine secreted by activated T cells, has been shown to play an important role in neuropathic pain induced by nerve injury and is also produced in various cell types in the CNS, especially in dorsal root ganglia (DRG). However, the role of CCL-1 in the CNS and the effects on microglia remains unclear. Here we showed the multiple effects of CCL-1 on microglia. We first showed that CCR-8, a specific receptor for CCL-1, was expressed on primary cultured microglia, as well as on astrocytes and neurons, and was upregulated in the presence of CCL-1. CCL-1 at concentration of 1 ng/ml induced chemotaxis, increased motility at a higher concentration (100 ng/ml), and increased proliferation and phagocytosis of cultured microglia. CCL-1 also activated microglia morphologically, promoted mRNA levels for brain-derived neurotrophic factor (BDNF) and IL-6, and increased the release of nitrite from microglia. These indicate that CCL-1 has a role as a mediator in neuron-glia interaction, which may contribute to the development of neurological diseases, especially in neuropathic pain., (Copyright © 2013 The Authors.

- Abstract
A 44-year-old man with Eisenmenger's syndrome due to ventricular septal defect (VSD) was listed for lung transplantation. The patient's condition was complicated by a giant pulmonary artery (PA) aneurysm. Concurrent VSD closure and total reconstruction of the recipient PA with the donor aorta were planned. When the patient underwent bilateral lung transplantation, the aortic graft obtained turned out to be too short to complete the reconstruction. A PA graft made of the recipient's pericardium was successfully interposed between the donor's PA and the donor's aortic graft., (Copyright © 2013 The Society of Thoracic Surgeons.
