Abstract
The donation of the organs after brain death (DBD) has increased after the revision of the law in 2010 and the total number of heart transplantation( HTx) has reached to over 500 in Japan. However, donor shortage is critical as the annual number as remaining under 100 with unneglectable number of waiting deaths. Recently, HTx under donation after controlled circulatory death( cDCD) has been promoted in United Kingdom (UK) and Australia with promising outcomes. The cDCD appears to be an important option to expand the donor pool in Japan. Nation-wide and cross-cutting action among transplantation organs is warranted. Status of cDCD HTx in abroad and the domestic issues are reviewed.

Abstract
BACKGROUND We sought to evaluate our distributed practice program developed for training for beating heart anastomosis by employing a novel beating heart simulator. METHODS Eleven trainees watched and reviewed instructional video recordings of coronary anastomosis methods with a BEAT + YOUCAN training device, then performed coronary anastomosis procedures under a beating condition. Next, they participated in a four-hour training program developed by faculty surgeons. Ten different anastomosis components were assessed on a five-point rating scale (5, good; 3, average; 1, poor). After finishing the training program, each trainee again performed a coronary anastomosis procedure. Component scores were then compared before and after the training program. RESULTS The mean time to completion of the procedure improved from 1033 ± 424 to 795 ± 201 s (p < 0.05). Assessment scores improved from 1.88 ± 0.41 to 2.57 ± 0.30 (p < 0.05). Improvements in some technical components related to handling of instruments were noted (p < 0.05), whereas no significant improvement was seen with arteriotomy, graft orientation, suture management, or knot tying after finishing the training program. CONCLUSION Trainees who participated in our four-hour focused training program for coronary anastomosis with a novel beating heart simulator showed improved ability under the beating condition in regard to technical skills related to handling instruments.

Abstract
BACKGROUND PET (positron emission tomography) and CSF (cerebrospinal fluid) provide the "ATN" (Amyloid, Tau, Neurodegeneration) classification and play an essential role in early and differential diagnosis of Alzheimer's disease (AD). OBJECTIVE Biomarkers were evaluated in a Japanese multicenter study on cognitively unimpaired subjects (CU) and early (E) and late (L) mild cognitive impairment (MCI) patients. MEASUREMENTS A total of 38 (26 CU, 7 EMCI, 5 LMCI) subjects with the age of 65-84 were enrolled. Amyloid-PET and FDG-PET as well as structural MRI were acquired on all of them, with an additional tau-PET with 18F-flortaucipir on 15 and CSF measurement of Aβ1-42, P-tau, and T-tau on 18 subjects. Positivity of amyloid and tau was determined based on the positive result of either PET or CSF. RESULTS The amyloid positivity was 13/38, with discordance between PET and CSF in 6/18. Cortical tau deposition quantified with PET was significantly correlated with CSF P-tau, in spite of discordance in the binary positivity between visual PET interpretation and CSF P-tau in 5/8 (PET-/CSF+). Tau was positive in 7/9 amyloid positive and 8/16 amyloid negative subjects who underwent tau measurement, respectively. Overall, a large number of subjects presented quantitative measures and/or visual read that are close to the borderline of binary positivity, which caused, at least partly, the discordance between PET and CSF in amyloid and/or tau. Nine subjects presented either tau or FDG-PET positive while amyloid was negative, suggesting the possibility of non-AD disorders. CONCLUSION Positivity rate of amyloid and tau, together with their relationship, was consistent with previous reports. Multicenter study on subjects with very mild or no cognitive impairment may need refining the positivity criteria and cutoff level as well as strict quality control of the measurements.

Abstract
Abstract
Background
Although pulmonary endarterectomy (PEA) is an established surgical treatment for chronic thromboembolic pulmonary hypertension (CTEPH), a part of patients after PEA show residual pulmonary hypertension, leading to limited exercise capacity. Recently, several studies have indicated that balloon pulmonary angioplasty (BPA) improves hemodynamics, exercise capacity and prognosis in inoperable CTEPH patients. However, the effects of BPA in patients with residual pulmonary hypertension after PEA remain to be elucidated.
Aim
In the present study, we investigated comprehensive efficacy of BPA on hemodynamics, exercise capacity and right ventricular function in those with residual pulmonary hypertension after PEA.
Methods
From October 2010 to February 2019, 227 patients with CTEPH underwent PEA in our institution. Right heart catheterization after PEA (median follow up period from PEA to right heart catheterization 39 [10.5, 90] months) showed that 55 patients showed residual PH (mean pulmonary artery pressure (mPAP)≥25mmHg), and 38 of them referred to BPA (mean age 57 years old, male 8 (21%)) due to residual symptoms. In 29 out of 38 patients (76%) who completed BPA and underwent follow-up right heart catheterization, we examined hemodynamics, exercise capacity and right ventricular function before and after BPA. Follow-up examination was performed 3 months after last BPA session.
Results
In this study population (N=29), PEA significantly improved mPAP (47±7 to 38±10 mmHg), pulmonary vascular resistance (PVR, 14.6±4.6 to 9.2±4.6 WU) and right ventricular ejection fraction measured by magnetic resonance imaging (26.6±11.3 to 38.4±6.8%) (Figure). Median period from PEA to first BPA procedure was 42 [13.5, 94] months. Total session number during study period was 160 sessions, and mean session number of BPA was 5.5±1.5 per patient. Follow-up study revealed that BPA additionally improved mPAP (38±10 to 27±8 mmHg) and PVR (9.2±4.6 to 5.1±2.2 WU) (Figure). Similarly, 6-minute walk distance (393±125 to 452±125 m) and peak VO2 (16.4±3.8 to 18.1±4.6 ml/min/kg, p<0.05) were increased, and WHO functional class also significantly improved by BPA (I/II/III/IV, 0/21/8/ 0 to 1/27/1/0, p<0.01). In addition, right ventricular ejection fraction (38.4±6.8 to 44.2±7.1%) was increased after BPA (Figure). There were no procedure-related deaths and major lung injuries requiring oral intubation during study period. 3-year survival in patients after BPA was 100% (median follow-up period after last BPA session, 32 [18, 46] months).
Conclusion
In CTEPH patients with residual pulmonary hypertension after PEA, additional BPA significantly improved hemodynamics, right ventricular function, exercise capacity and residual symptoms without severe complications, leading to good prognosis. These results suggest that combination therapy of PEA and BPA could be an effective therapeutic option for post PEA patients with residual symptoms and exercise limitation.

Abstract
BACKGROUND AND PURPOSE Leptomeningeal glioneuronal heterotopia of the brain stem and cerebral migration abnormality were pathologically reported in Fukuyama congenital muscular dystrophy, but the radiologic assessments of the brain stem and cerebral venous system (which may be involved in the development of the anomaly) were insufficient. Here, we evaluated the brain stem and cerebral veins on MR imaging in patients with Fukuyama congenital muscular dystrophy. MATERIALS AND METHODS We retrospectively reviewed the MR imaging findings of 27 patients with Fukuyama congenital muscular dystrophy. We visually assessed the hypoplasia, superficial structures, and signal intensity of the brain stem on T2WI, FLAIR, and double inversion recovery images and the cerebral, superficial, and deep veins with and without hemorrhage on T2WI and SWI. RESULTS Brain stem fluffy structures were seen in 96.3% of the cases on T2WI. Superficial high signal intensity on T2WI and FLAIR images was seen in 96.3% and 92.6%, respectively. Abnormally located superficial vessels beneath the cortex were seen in 11.1% on T2WI. Hypoplasia of the superficial cerebral veins was noted in all patients who underwent SWI. Dilated and tortuous subependymal veins were seen in 40.0% on SWI. Hemorrhages were seen in 11.1% on T2WI and in 60.0% on SWI. CONCLUSIONS Superficial brain stem structural and signal abnormalities would be useful MR imaging findings to diagnose Fukuyama congenital muscular dystrophy as well as venous system abnormalities. Clinicians must keep in mind that this disease has a high risk of hemorrhage.

Abstract
Abstract
Background
Introduction: Several studies have reported that durable polymer drug-eluting stents could cause delayed healing and late catch-up. Although biodegradable polymer everolimus-eluting stents (BP-EES) might solve these problems, there is few data about mid-term clinical outcomes of BP-EES compared with durable polymer everolimus-eluting stents (DP-EES).
Purpose
This study aimed to compare mid-term clinical outcomes between BP-EES and DP-EES.
Methods
Between January to December 2016, 206 consecutive patients were treated with BP-EES and 177 consecutive patients were treated with DP-EES in our Heart Center. The primary endpoint was 3-year cumulative incidence of target lesion failure (TLF) defined as cardiac death, target vessel-related myocardial infarction and clinical-driven target lesion revascularization. Moreover, clinical-driven target vessel revascularization (TVR) and definite stent thrombosis (ST) were also evaluated.
Results
After propensity score matching, 160 patients were selected in each group. At 3 years, the cumulative incidences of TLF were 4.1% in BP-EES group vs. 7.9% in DP-EES (p = 0.12). Similarly, those of clinical-driven TVR were not different between the 2 groups (10.9% vs. 8.0%, p = 0.39). The incidence of definite ST in BP-EES tended to be higher than in that of DP-EES (BP-EES vs. DP-EES; 0% vs. 1.8%, p = 0.06).
Conclusions
There were no significant differences of TLF between BP-EES and DP-EES within 3 years. In this study, BP-EES seems to prevent definite ST and be safer than DP-EES in mid-term.

Abstract
Monozygotic twin embryos which can efficiently be produced by blastomere separation and aggregation of early cleavage stages of embryos using commercially provided well-of-the-well (WOW) culture dish. Phytohaemagglutinin (PHA) is a plant lectin that binds to and aggregates on the surface of animal cells, but also contains toxicity that causes food poisoning. The present study was conducted to evaluate the toxicity to embryos and the effect to development of isolated blastomeres on PHA-supplemented WOW culture. Embryos were produced using oocytes from ovaries collected at an abattoir by IVM, IVF, and invitro culture (IVC). The tissue culture medium 199 supplemented with 5% calf serum (CS), Brackett-Oliphant solution supplemented with 10mgmL−1 bovine serum albumin, and CR1aa medium containing 5% CS were used for each culture step. For the evaluation of PHA toxicity, 89 embryos that developed to the 5-8-cell stage were obtained at Day 2 after insemination. Each embryo was cultured in a droplet of 5 µL/embryo IVC culture medium supplemented with or without PHA. For the evaluation of PHA to development of isolated blastomeres, 111 of 8-cell stage embryos were obtained 48-54h post-insemination. Zonae pellucidae were removed by exposure to 0.25% pronase. Then, embryos were separated into single blastomeres by gentle pipetting in IVC medium. Each four blastomeres were formed in the shape of a bunch inside the thin cylinder at the tip of the Pasteur pipette by gentle pipetting. Then, each mass of blastomeres in each 60 masses was cultured individually in 5-µL droplets of IVC medium supplemented with or without PHA on the flat surface of a tissue culture dish. On the other hand, each four blastomeres were introduced into a single conical micro-well each having a diameter and depth of ~287µm and 168µm (Dai Nippon Printing). This culture of blastomeres was performed covered with a droplet of 2.5µL well−1 IVC medium supplemented with or without PHA in each 50 or 52 wells. In all of investigations, PHA was used at 50µgmL−1 (Akagi et al. 2011 J. Reprod. Dev. 57). Statistical analysis was performed using Student's t-test and analysis of variance. The blastocyst formation rate (71.1±2.3% vs. 72.7±1.7%), total cell number (120 vs. 122), and inner cell mass cell number (47 vs. 51) at Day 7 after IVF did not differ between PHA-supplemented and PHA-free group in the toxicity test, respectively. In the blastomere culture, the blastocyst formation rate was very low (10.0±5.9% vs. 5.0±2.9%) regardless of the PHA supplementation in drops on the flat surface of a tissue culture dish. On the other hand, blastocyst formation was improved using the WOW culture dish (24.0±3.6% vs. 40.4±7.6%) but there was no difference with or without PHA supplementation. Although nontoxicity of PHA and efficacy of WOW culture for isolated-aggregated blastomeres were confirmed, no improvement of PHA supplementation on development was observed in this study. Subsequently, experiments on the optimum concentration of PHA for aggregation and development of blastomeres in WOW culture are required.

This study aims to develop quality indicators (QIs) for the management of AAD, and to evaluate the associations between QIs and outcomes of AAD in a Japanese nationwide administrative database.
Methods
A total of 18,348 patients suffered from AAD (Type A: 10,131, Type B: 8,217) in the Japanese Registry of All Cardiac and Vascular Diseases database between 2012 and 2015 were studied. A systematic review was performed to establish initial index items for QIs. Evaluation was performed through the expert consensus meeting using a Delphi method. Associations between developed QIs and the mortality were determined by multivariate mixed logistic regression analyses.
Results
A total of nine QIs (five structural and four processatic) were developed. Achievements of developed QIs (High: 7–9, Middle: 4–6, Low: 0–3) were significantly associated with lower in-hospital mortality even after adjustment for covariates in both type A (Middle: odds ratio [OR], 0.257; 95% confidence interval [CI], 0.211–0.312; P<0.001; High: OR, 0.064; 95% CI, 0.047–0.086; P<0.001 vs. Low) and type B (Middle: OR, 0.447; 95% CI, 0.338–0.590; P<0.001; High: OR, 0.128; 95% CI, 0.077–0.215; P<0.001 vs. Low). Additionally, achievements of structural and processatic QIs were consistently associated with reduced in-hospital mortality.
QIs and in-hospital mortality
Conclusions
Developed QIs for AAD management were significantly associated with lower in-hospital mortality. Evaluation of each hospital's management with QIs could be helpful to equalize quality of treatment and to fill the evidence-to-practice gaps in the real-world treatment.

Abstract
Abstract
Background and introduction
Diabetic patients are at high risk of adverse cardiovascular events after percutaneous coronary intervention (PCI) even with durable polymer drug-eluting stents. A biodegradable polymer everolimus-eluting stents (BP-EES) might improve clinical outcomes in patients with diabetes mellitus.
Purpose
This study aimed to compare the mid-term clinical outcomes between BP-EES and durable polymer everolimus-eluting stents (DP-EES) in diabetic patients.
Methods
We investigated consecutive 383 patients treated with BP-EES or DP-EES at our Heart Center between January and December 2016. Among these patients, 155 (40.5%) patients had diabetes mellitus. The primary endpoint was 3-year cumulative incidence of target lesion failure (TLF) defined as target vessel-related myocardial infarction (MI) and clinical-driven target lesion revascularization (TLR). Moreover, the incidence of definite stent thrombosis (ST) was also evaluated.
Results
After propensity score matching, 148 patients were divided into 2 groups (BP-EES; N=74, DP-EES; N=74). The 3-year cumulative incidences of TLF were significantly lower in BP-EES group than in DP-EES group (BP-EES vs. DP-EES; 1.4% vs. 11.4%, p=0.01). The incidence of cardiac death, target vessel-related MI, and definite ST were none in the both group.

Conclusions
In diabetic patients, the incidence of TLR within 3 years was significantly lower in BP-EES than in DP-EES. In PCI for diabetic patients, BP-EES might improve clinical outcomes compared to DP-EES.

Abstract
In vitro-produced (IVP) embryos are more easily damaged by cryopreservation than in vivo-derived embryos. Therefore, transportation of fresh IVP embryos in a manner that can maintain viability is necessary. This study was conducted to determine the preferable culture conditions for transport of embryos at 5 days post-insemination (dpi) in 1.5-mL microtubes. Cumulus-oocyte complexes derived from an abattoir were matured and then inseminated with frozen-thawed semen. Presumptive zygotes were cultured in mCR1aa (CR1)+5% calf serum (CS) until use. In Exp. 1, embryos with 5 blastomeres at 5 dpi were randomly assigned to 1 of 3 groups: 25mM Hepes-CR1aa (H-CR1)+5% CS or 25mM Hepes-M199 (H-M199)+5% CS in air, or CR1 in 5% CO2. Embryos were cultured in microdrops overlaid with liquid paraffin in a petri dish for 48h at 38.5°C. In Exp. 2, the optimal number of embryos to culture per microtube was assessed. Presumptive zygotes were cultured in groups of 20, 40, or 80 in 1mL of CR1 covered with liquid paraffin in microtubes in an incubator at 38.5°C in 5% CO2 until 7 dpi. For Exp. 3, culture of embryos in microtubes in a portable incubator was tested. At 5 dpi, 5-cell embryos (n=17 to 36 per microtube) were statically cultured in 1mL of CR1 or H-CR1 in microtubes in a portable incubator set at 38.5°C for 48h. The CR1 was pre-equilibrated in an incubator in 5% CO2 for 24h before use. Embryos were harvested from microtubes after 48h and were then cultured in microdrops of CR1 overlaid with liquid paraffin in a petri dish in an incubator at 38.5°C in 5% CO2 until 8 dpi. In Exp. 4, embryos (n=29 to 39 five-cell embryos per microtube) were transported in a portable incubator by land for 1000km over a period of 44h using the same conditions as in Exp. 3. Control embryos were statically cultured in microdrops of CR1 in an incubator in 5% CO2. Statistical analyses were carried out by ANOVA (Exp. 1 and 2), t-test (Exp. 3), or Fisher’s exact test (Exp. 4). In Exp. 1, there was no effect (P>0.05) of culture medium on blastocyst development at 7 dpi (27.6±2.3, 25.7±7.2, and 17.3±2.9% for CR1, H-CR1, and H-M199, respectively). In Exp. 2, blastocyst development at 7 dpi was not affected (P>0.05) by the number of presumptive zygotes cultured per microtube (43.6±8.3, 42.4±4.0, and 39.9±2.9% for 20, 40, and 80 presumptive zygotes, respectively). In Exp. 3, blastocyst development at 8 dpi was not affected (P>0.05) by culture medium (60.7±7.4 and 53.1±4.4% for CR1 and H-CR1, respectively); however, the pH of CR1 changed from 7.5 to 8.1 at 48h after culture. In Exp. 4, blastocyst development at 8 dpi was not affected (P>0.05) by transport (57.1, 64.4, and 75.5% for CR1, H-CR1, and control, respectively). These results indicate that IVP embryos harvested at 5 dpi can be transported by portable incubator with no effect on embryo development to the blastocyst stage.

Abstract
We have reported monozygotic twin calves that can be produced efficiently by blastomere separation of 2-cell stage embryos and by the use of a commercially provided well-of-the-well culture dish (Hashiyada 2017 J. Reprod. Dev.). The present study was conducted to evaluate the effect of a culture supplement, l-ascorbic acid 2-phosphate (AA-2P), a sustained antioxidant substance that reduces reactive oxygen species. Embryos were produced using oocytes from ovaries collected at an abattoir by in vitro maturation, IVF, and in vitro culture (IVC). TCM199 supplemented with 5% calf serum, Brackett-Oliphant solution supplemented with 10mg mL−1 BSA, and CR1aa containing 5% calf serum were used for each culture step. Two-cell stage embryos were obtained 24 to 27h post-insemination (hpi). Zonae pellucidae were removed by exposure to 0.25% pronase. Then, embryos were separated into each blastomere by gentle pipetting in IVC medium. Each blastomere was introduced into a single conical micro-well of 25 wells, each having a diameter and depth of ~287 and 168µm (Dai Nippon Printing, Tokyo, Japan). Culture of blastomeres in wells was performed covered with a droplet of 2.5 µL/well IVC medium supplemented with 0 (n=212), 250 (n=214), 500 (n=206), and 750 µM (n=204) of AA-2P. The blastocyst formation rate at Day 8 after IVF, the quality of blastocysts assessed by morphological observation, and the cell numbers were compared among each concentration of AA-2P. In addition, the developmental speed to the blastocyst stage was analysed using time-lapse cinematography for 0 and 500 µM of AA-2P (n=40, respectively). Statistical analysis was performed using Fisher’s exact test and ANOVA. The blastocyst formation rate (32-40%), the total cell number (108-114), and inner cell mass cell number (26-28) did not differ among groups. The time to reach the 4-cell stage was significantly shorter in media supplemented with 0 µM (43 hpi) than with 500 µM (52 hpi); however, the time to reach the blastocyst stage did not differ (150 and 155 hpi, respectively). Regarding the proportion of quality grade 1 to 3 blastocysts and the developmental speed to the blastocyst stage, high-quality grade 1 embryos were significantly faster than those of middle and low-quality grade 2 and 3 ones in 0 (145 v. 154 hpi; P<0.05) and 500 µM (150v. 158 hpi; P<0.05) supplemented medium. In this experiment, no effect of AA-2P was observed for the culture of isolated blastomeres from 2-cell stage embryos, although it was suggested that blastomeres with high developmental competence reach the blastocyst stage faster, which might reflect the quality of the embryos.

Abstract
Excessive expansion of Staphylococcus aureus is associated with several skin diseases, including atopic dermatitis (AD). Recently, we have demonstrated that washing skins with ultra-pure soft water containing little bivalent metal ions improved skin conditions of atopic subjects. In this study, we investigated the roles of calcium or magnesium on the proliferation of S. aureus both in vitro and in vivo. Depletion of calcium and magnesium in the culture medium significantly suppressed the expansion of S. aureus growth. When S. aureus, diluted with water containing calcium/magnesium at the concentration of medium-hard water (83·0 mg l-1 as CaCO3 ) or the one that contains little calcium/magnesium, was applied onto the tape-stripped skin of Hos:HR-1 mice, growth of S. aureus in water without those minerals on the skin was suppressed. These results suggest that depletion of both calcium and magnesium abrogate the proliferation of S. aureus not only in the culture system but also on the skin surface of mice. Since colonization of S. aureus on the skin is well-known to exacerbate AD symptoms, usage of ultra-pure soft water containing less calcium and magnesium may improve the skin condition through the suppression of S. aureus growth on the skin of patients with skin problems. SIGNIFICANCE AND IMPACT OF THE STUDY This study demonstrates the importance of calcium and magnesium for the colonization and growth of Staphylococcus aureus by using both in vitro culture systems and in vivo experiments on the murine skin. Our results indicate that the removal of these metal ions is probably beneficial for protecting the skin from S. aureus. Thus, using ultra-pure soft water without metal ions may improve the skin condition of patients with skin problems through the protection from S. aureus colonization.

Abstract
Background Companion animals are also affected by IgE‐mediated allergies, but the eliciting molecules are largely unknown. We aimed at refining an allergen microarray to explore sensitization in horses and compare it to the human IgE reactivity profiles. Methods Custom‐designed allergen microarray was produced on the basis of the ImmunoCAP ISAC technology containing 131 allergens. Sera from 51 horses derived from Europe or Japan were tested for specific IgE reactivity. The included horse patients were diagnosed for eczema due to insect bite hypersensitivity, chronic coughing, recurrent airway obstruction and urticaria or were clinically asymptomatic. Results Horses showed individual IgE‐binding patterns irrespective of their health status, indicating sensitization. In contrast to European and Japanese human sensitization patterns, frequently recognized allergens were Aln g 1 from alder and Cyn d 1 from Bermuda grass, likely due to specific respiratory exposure around paddocks and near the ground. The most prevalent allergen for 72.5% of the tested horses (37/51) was the 2S‐albumin Fag e 2 from buckwheat, which recently gained importance not only in human but also in horse diet. Conclusion In line with the One Health concept, covering human health, animal health and environmental health, allergen microarrays provide novel information on the allergen sensitization patterns of the companion animals around us, which may form a basis for allergen‐specific preventive and therapeutic concepts.

Abstract
The pancreatic duct epithelium secretes the HCO3−-rich pancreatic juice. The HCO3− transport across the luminal membrane has been proposed to be mediated by SLC26A Cl−–HCO3− exchangers. To examine the electrophysiological properties of Cl−–HCO3− exchangers, we directly measured HCO3− conductance in the luminal membrane of the interlobular pancreatic duct cells from guinea pigs using an inside-out patch-clamp technique. Intracellular HCO3− increased the HCO3− conductance with a half-maximal effective concentration value of approximately 30 mM. The selectivity sequence based on permeability ratios was SCN− (1.4) > Cl− (1.2) = gluconate (1.1) = I− (1.1) = HCO3− (1.0) > methanesulfonate (0.6). The sequence of the relative conductance was HCO3− (1.0) > SCN− (0.7) = I− (0.7) > Cl− (0.5) = gluconate (0.4) > methanesulfonate (0.2). The current dependent on intracellular HCO3− was reduced by replacement of extracellular Cl− with gluconate or by H2DIDS, an inhibitor of Cl−–HCO3− exchangers. RT-PCR analysis revealed that the interlobular and main ducts expressed all SLC26A family members except Slc26a5 and Slc26a8. SLC26A1, SLC26A4, SLC26A6, and SLC26A10 were found to be localized to the luminal membrane of the guinea pig pancreatic duct by immunohistochemistry. These results demonstrate that these SLC26A Cl−–HCO3− exchangers may mediate the electrogenic HCO3− transport through the luminal membrane and may be involved in pancreatic secretion in guinea pig ducts.

Abstract
BACKGROUND AND PURPOSE Although Diffeomorphic Anatomical Registration Through Exponentiated Lie Algebra (DARTEL) has been introduced as an alternative to conventional voxel-based morphometry, there are scant data available regarding the optimal image-processing settings. The aim of this study was to optimize image-processing and ROI settings for the diagnosis of Alzheimer disease using DARTEL. MATERIALS AND METHODS Between May 2002 and August 2014, we selected 158 patients with Alzheimer disease and 198 age-matched healthy subjects; 158 healthy subjects served as the control group against the patients with Alzheimer disease, and the remaining 40 served as the healthy data base. Structural MR images were obtained in all the participants and were processed using DARTEL-based voxel-based morphometry with a variety of settings. These included modulated or nonmodulated, nonsmoothed or smoothed settings with a 4-, 8-, 12-, 16-, or 20-mm kernel size. A z score was calculated for each ROI, and univariate and multivariate logistic regression analyses were performed to determine the optimal ROI settings for each dataset. The optimal settings were defined as those demonstrating the highest χ2 test statistics in the multivariate logistic regression analyses. Finally, using the optimal settings, we obtained receiver operating characteristic curves. The models were verified using 10-fold cross-validation. RESULTS The optimal settings were obtained using the hippocampus and precuneus as ROIs without modulation and smoothing. The average area under the curve was 0.845 (95% confidence interval, 0.788-0.902). CONCLUSIONS We recommend using the precuneus and hippocampus as ROIs without modulation and smoothing for DARTEL-based voxel-based morphometry as a tool for diagnosing Alzheimer disease.

Abstract
Bioprostheses currently used for replacement of diseased cardiovascular tissue are preserved and partially protected from immune rejection through chemical fixation. However, after implantation, chemically preserved (fixed) material has limited durability and lacks the ability to revitalize through cellular ingrowth and remodeling. As an alternative to fixation, we aimed at thoroughly removing antigens from tissue, leaving an intact scaffold, suitable for integration and revitalization in the host. Extensive washing of porcine heart valves with a mixture of two detergents (SDS and Triton X-100) yielded an intact matrix devoid of cells and depleted of soluble proteins that was minimally immunogenic in rabbits. A detailed characterization of the biomechanics and durability of the tissue is under way. If the lack of immunogenicity is confirmed in primates, our results would suggest that a detergent-washed, unfixed porcine heart valve can be an attractive non-inflammatory scaffold for heart valve regeneration in humans.

Abstract
Monozygotic twin bovine embryos can be produced by blastomere separation of 2-cell embryos and commercial well-of-the-well (WOW) culture dish (Hashiyada et al. 2016 Reprod. Fertil. Dev. 28, 178) obtaining 60% and 48% of blastocyst formation and monozygotic blastocyst pairs, respectively. The present study was conducted to evaluate the fertility of blastocysts derived from this production system in Japanese Black beef cattle. Embryos were produced using oocytes collected by ovum pick-up technique. TCM-199 supplemented with 5% calf serum (CS), Brackett-Oliphant solution supplemented with 10 mg mL−1 BSA, and CR1aa containing 5% CS, were used for each culture step: in vitro maturation, fertilization, and culture (IVM,IVF, and IVC). Two-cell stage embryos were obtained 24 to 27 h post-insemination. Zonae pellucidae were removed by exposure to 0.25% pronase. Then, embryos were separated into blastomeres by gentle pipetting in IVC medium. Each blastomere was introduced into a single conical microwell of 25 wells, each having a diameter and depth of ~287 μm and 168 μm (Dai Nippon Printing, Tokyo, Japan). Blastomeres in wells were cultured covered with a droplet of 2.5 μL of IVC medium/well. The developed blastocysts in pairs on 7 days post-insemination were used for transfer. Single embryos of monozygotic twin embryos were transferred to Japanese Black cattle with a generally small body frame to produce twin calves from a set of recipients. Twin embryos were transferred in pairs to unilateral of uterus of non-lactating Holstein cows. Pregnancy and twin pregnancy were determined at 30 days of gestation by ultrasonography and were reconfirmed at 60 days with detection of fetal loss. Statistical significance was analysed by Fisher’s exact test. There was no significant difference in pregnancy rate or twin pregnancy rate between single embryo transfer (7/14, 50% and 2/7, 28.6%) and twin embryo transfer (9/21, 42.9% and 4/21, 19%). In either transfer method, fetal loss was not observed in diagnosis carried out at 60 days by ultrasonography. To date, 2 pairs of twin calves have been obtained from twin pregnant cows by twin embryo transfer within the normal range of gestation length (286 and 288 days) and birth weight (31-40 kg). These results indicate that blastocysts developed from blastomeres separated from 2-cell embryos by culturing with commercial WOW culture dish had fertility similar to that of intact embryos derived from standard in vitro culture and further demonstrate the possibility of production of normal twin calves.

Abstract
It has been reported that in vitro- and in vivo-matured oocyte obtained from fully growth follicles have high developmental competence. Furthermore, the timing of cleavage in early embryo after IVF affect pregnancy success after embryo transfer. It is still unknown whether origin of oocyte affects the timing of cleavage. In this study, we examined the influence of oocyte origin on cleavage timing of early embryo after IVF. Japanese Black cows were used as donors. Oocytes derived from non-stimulation follicles (control: CON), fully grown follicles after super-stimulation treatment (SST) and follicles just before ovulation after ovulation-induction treatment (in vivo-matured oocyte: VIVO) were obtained by ovum pick-up (OPU). In the CON group, OPU was conducted on arbitrary days except oestrus. In SST group, dominant follicles were aspirated and a CIDR was inserted into the vagina on Day 0, and then FSH was injected twice a day from the evening of Day 1 to the morning of Day 5 with decreasing doses in total 20 AU. In the evening of Day 4, prostaglandin F2α (0.5 mg of cloprostenol) was administered. On Day 6, SST oocytes were collected after CIDR withdrawl. In the VIVO group, the treatment was carried out as SST until prostaglandin F2α administration, and then CIDR withdrawal and administration of gonadotropin-releasing hormone (GnRH, 0.2 mg of fertirelin acetate) performed on the evening of Day 4 and morning of Day 5, respectively. The VIVO oocytes were collected at 25 to 26 h after GnRH. The CON and SST oocytes were inseminated after 20 to 22 h of IVM, and VIVO oocytes were inseminated at 30 h after GnRH, with 3 × 106 sperm mL−1, respectively. After 6 h of IVF, presumptive zygotes were individually cultured for 168 h, using a well-of-the-well dish (Dai-Nippon-Print, Japan) and were observed by time-lapse cinematography (CCM-4MZS; Astec, Japan) to analyse the cleavage timing of embryos. Oxygen consumption (O2) was measured in blastocysts on 168 hpi with a scaning electrochemical microscopy system (HV-405SP; Hokuto Denko, Japan). Statistical analysis was carried out by Steel-Dwass test for the timing of cleavage and Tukey-Kramer test for O2. In CON (n = 15), SST (n = 25), and VIVO (n = 36), the time of first cleavage was 27.5, 29.1, and 26.1 hpi, that of second cleavage was 38.9, 40.3, and 36.0 hpi, and that of third cleavage was 48.5, 46.1, and 45.9 hpi, respectively. These cleavage times were shorter in VIVO than in CON and SST (P < 0.01). The time interval between first and second cleavage (2nd cell cycle) was shorter in VIVO (10.1; P < 0.01) than CON (11.4) and SST (11.2). The time interval between second and third (3rd cell cycle) were shorter (P < 0.01) in SST (9.4) than in VIVO (10.1), and in VIVO than in CON (10.2), respectively. Consumption of O2 was lower (P < 0.01) in CON (0.61 × 10−14 mol s−1) than in SST (0.94 × 10−14 mol s−1) and VIVO (0.94 × 10−14 mol s−1). These results suggest that the origin of oocyte influences the length of cell cycle and O2 consumption of blastocyst producted in vitro.

Abstract
Neuronal intranuclear inclusion disease is a neurodegenerative disorder pathologically characterized by eosinophilic hyaline intranuclear inclusions. A high-intensity signal along the corticomedullary junction on DWI has been described as a specific MR imaging finding of the cerebrum in neuronal intranuclear inclusion disease. However, MR imaging findings of the cerebellum in neuronal intranuclear inclusion disease have not been fully evaluated. Here, we review MR imaging findings of the cerebellum in a series of 8 patients with pathologically confirmed neuronal intranuclear inclusion disease. The MR imaging results showed cerebellar atrophy (8/8 patients) and high-intensity signal on FLAIR images in the medial part of the cerebellar hemisphere right beside the vermis (the "paravermal area") (6/8) and in the middle cerebellar peduncle (4/8). The paravermal abnormal signals had a characteristic distribution, and they could be an indicator of the diagnosis of neuronal intranuclear inclusion disease even when using the results of past MR imaging examinations in which DWI findings were not examined.

Abstract
Early detection of gestation is important in the bovine industry. New methods have been developed to detect gene expression in leucocytes induced by interferon-tau (IFNT) as gestation biomarkers. However, it is debatable which blood cell is suitable for detecting gene expression. This study was aimed at confirming whether granulocytes respond to IFNT specifically. Granulocytes and mononuclear cells (MNCs) from cows, and several types of bovine cultured cells, were treated with recombinant (r) IFNT and gene expression was analysed by quantitative real-time reverse transcriptase (RT)-PCR and microarray analysis. Expression levels of IFN receptors (R1 and R2) were approximately 30- to 900-fold higher in granulocytes than in other cultured cells, and 1.5- to 2.5-fold higher in MNCs than in granulocytes. Microarray analysis following a 2h recombinant IFNT (rIFNT) treatment revealed expression changes for 900 genes in granulocytes. Genes with expression changes included known IFN-stimulated genes (ISGs; ISG15, OAS1, MX1, and MX2). Eighteen genes were selected following granulocyte microarray analysis and their expression changes were confirmed in early gestation, which revealed that nine genes had significantly higher expression levels in pregnant than in non-pregnant animals. In conclusion, granulocytes specifically responded to rIFNT treatment and the resulting gene expression changes correlated with those in vivo. Microarray analysis indicated that various genes showed expression changes in rIFNT-treated granulocytes, which may result in the identification of alternate candidate genes for the early detection of gestation. These results strongly indicate that gene expression in granulocytes is a suitable tool to determine pregnancy status.

Abstract
The density of intraepidermal nerve fibres has been shown to be higher in itchy dry skin than in healthy skin, suggesting that epidermal hyperinnervation is at least partly involved in peripheral itch sensitization. We investigated whether oral administration of milk-derived phospholipids (MPLs) would inhibit epidermal hyperinnervation in a mouse model of dry skin. We found that the number of intraepidermal nerve fibres was significantly lower in the MPL group than in the control group. Expression of nerve growth factor (NGF) levels in the epidermis was significantly decreased by oral administration of MPLs, whereas expression of semaphorin (Sema)3A, a nerve repulsion factor, was increased in the MPL group. These results suggest that dietary MPLs attenuate the penetration of nerve fibres into the epidermis by reducing epidermal NGF levels and increasing Sema3A level. Thus, dietary MPLs may have beneficial effects in the prevention and/or alleviation of dry skin-induced itch by reducing intraepidermal nerve fibre density.

The first measurement of transverse-spin-dependent azimuthal asymmetries in the pion-induced Drell-Yan (DY) process is reported. We use the CERN SPS 190 GeV/c π^{-} beam and a transversely polarized ammonia target. Three azimuthal asymmetries giving access to different transverse-momentum-dependent (TMD) parton distribution functions (PDFs) are extracted using dimuon events with invariant mass between 4.3 GeV/c^{2} and 8.5 GeV/c^{2}. Within the experimental uncertainties, the observed sign of the Sivers asymmetry is found to be consistent with the fundamental prediction of quantum chromodynamics (QCD) that the Sivers TMD PDFs extracted from DY have a sign opposite to the one extracted from semi-inclusive deep-inelastic scattering (SIDIS) data. We present two other asymmetries originating from the pion Boer-Mulders TMD PDFs convoluted with either the nucleon transversity or pretzelosity TMD PDFs. A recent COMPASS SIDIS measurement was obtained at a hard scale comparable to that of these DY results. This opens the way for possible tests of fundamental QCD universality predictions.

Abstract
Increased survival rates after corrective or palliative surgery for complex congenital heart disease (CHD) in infancy and childhood are now being coupled with increased numbers of patients who survive to adulthood with various residual lesions or sequelae. These patients are likely to deteriorate in cardiac function or end-organ function, eventually requiring lifesaving treatment including heart transplantation. Although early and late outcomes of heart transplantation have been improving for adult survivors of CHD, outcomes and pretransplant management could still be improved. Survivors of Fontan procedures are a vulnerable cohort, particularly when single ventricle physiology fails, mostly with protein-losing enteropathy and hepatic dysfunction. Therefore, we reviewed single-institution and larger database analyses of adults who underwent heart transplantation for CHD, to enable risk stratification by identifying the indications and outcomes. As the results, despite relatively high early mortality, long-term results were encouraging after heart transplantation. However, further investigations are needed to improve the indication criteria for complex CHD, especially for failed Fontan. In addition, the current system of status criteria and donor heart allocation system in heart transplantation should be arranged as suitable for adults with complex CHD. Furthermore, there is a strong need to develop ventricular assist devices as a bridge to transplantation or destination therapy, especially where right-sided circulatory support is needed.

Abstract
Most of what we know about gene transcription comes from the view of cells as molecular machines: focusing on the role of molecular modifications to the proteins carrying out transcriptional reactions at a loci-by-loci basis. This view ignores a critical reality: biological reactions do not happen in an empty space, but in a highly complex, interrelated, and dense nanoenvironment that profoundly influences chemical interactions. We explored the relationship between the physical nanoenvironment of chromatin and gene transcription in vitro. We analytically show that changes in the fractal dimension, D, of chromatin correspond to simultaneous increases in chromatin accessibility and compaction heterogeneity. Using these predictions, we demonstrate experimentally that nanoscopic changes to chromatin D within thirty minutes correlate with concomitant enhancement and suppression of transcription. Further, we show that the increased heterogeneity of physical structure of chromatin due to increase in fractal dimension correlates with increased heterogeneity of gene networks. These findings indicate that the higher order folding of chromatin topology may act as a molecular-pathway independent code regulating global patterns of gene expression. Since physical organization of chromatin is frequently altered in oncogenesis, this work provides evidence pairing molecular function to physical structure for processes frequently altered during tumorigenesis.

Abstract
BACKGROUND Chronic allograft dysfunction (CAD) is a main cause of graft failure in kidney transplantation. METHODS We retrospectively analyzed 279 kidney transplant recipients who survived with a functioning graft for at least 2 years. CAD was defined as chronic graft deterioration, excluding other specific causes. We defined the pattern of decline in estimated glomerular filtration rate (eGFR), as follows: (1) "plateau" was defined as decline in eGFR ≤2 mL/min/1.73 m2/year; "long plateaus" were those lasting more than 5 years; (2) "rapid decline" was a decrease in eGFR ≥20 mL/min/1.73 m2/year. Patients diagnosed with CAD were categorized according to the occurrence of rapid decline and/or long plateau as follows: group 1, neither rapid decline nor long plateau; group 2, rapid decline only; group 3, long plateau only; and group 4, both rapid decline and long plateau. RESULTS From a total of 81 graft losses, 51 (63%) failed because of CAD, with a median of 9.4 years. Sixteen patients belonged to group 1, 14 to group 2, 12 to group 3, and nine to group 4. Mean graft survival times in the four groups were 7.7 ± 1.1, 6.1 ± 3.1, 16.2 ± 2.5, and 10.8 ± 3.6 years, respectively (P < .001). There were significant differences among groups in donor age, year of transplantation, mean eGFR at baseline, and acute rejection rate after transplantation. CONCLUSIONS The results indicate that this cohort of kidney transplant recipients who had CAD comprised subgroups with different clinical courses.

Abstract
The aim of this study was to evaluate the effect of administration of eCG and intrauterine infusion of povidone-iodine to promote the early recovery of ovary and uterus functions in early stage after delivery on postpartum beef cows. Thirty-three postpartum Japanese Black cows without retention of placenta were used for this investigation. After delivery, cows nursed colostrums to calves for several hours in a pen, and then were separated from calves and returned into a barn managed in a group. In experimental group (n = 14), on Day 10 (Day 0 = day of parturition), an intramuscular administration of 500 IU of eCG and infusion of 30 mL of 2% povidone-iodine into the uterus body were conducted. The untreated cows delivered in the same period were compared as a control group (n = 19). Cows were inseminated artificially using commercial Japanese Black frozen–thawed semen when standing oestrus was detected until Day 90. Pregnancy diagnosis was performed 30 days after insemination by ultrasonography. For all of the experimental group and 8 cows in the control group, the diameter of follicles >8 mm and the diameter of cross-section between endometrium in uterus of the implanted side at the point of ~2 cm from bifurcation of the uterus were measured using an ultrasound scanning machine connected to a 7.5-MHz convex probe. This monitoring was carried out every 10 days from Day 10 until the day of first oestrus (= insemination) or until Day 80 for non-returned oestrus cows. Data were analysed using Fisher’s exact test and ANOVA. The ratio of returned oestrus by Day 90 was 100% (14/14) in experimental group and 89.5% (17/19) in control group. The first oestrus day postpartum in the experimental group and the control group was the almost same: 52.9 ± 12.1 (24–88) days and 57.2 ± 19.9 (29–78) days, respectively. The conception rate until Day 90 tended to be higher (P = 0.07) in the experimental group (78.6%, 11/14) than in the control group (47.4%, 9/19). The days inseminated to cows that were conceived, was almost same between the experimental group (57.5 ± 18.6, 24–87 d) and the control group (55.4 ± 12.9, 36–78 d). The ratio of cows observed follicles more than 8 mm, was higher in the experimental group than control group on Day 50 (90.9% v. 50.0%; P = 0.09) and Day 60 (66.7% v. 0%; P < 0.05), respectively. The diameter of uterus tended to be lesser in the experimental group than in the control group on Day 30 (16.9 ± 2.8 mm v. 19.2 ± 2.8 mm; P = 0.09), and that regressed linearly to Day 30 in the experimental group however that was prolonged until Day 40 (16.4 ± 1.7 mm) in the control group. These results indicate that administration of eCG and uterus infusion of povidone-iodine at an early stage postpartum may promote the early recovery of ovary and uterus functions in beef cows.

Abstract
Bovine oocytes obtained by ovum-pick-up (OPU) following follicle growth treatment (FGT) have improved quality and competence (Imai et al. 2008 Reprod. Fertil. Dev. 20, 182). However, the effect of the presence of FSH or epidermal growth factor (EGF) like peptide during in vitro maturation (IVM) on the developmental competence of FGT oocytes has not been well known. This study was undertaken to examine the developmental competence of FGT oocytes following IVM in the presence of FSH (recombinant human FSH) or EGF-like peptide (amphiregulin; Areg) and IVF. Japanese Black cows (n = 17) were used as donors. Five days after arbitrary OPU (opu group), follicles ≥8 mm in diameter were aspirated again, a controlled internal drug release (CIDR) was inserted into the vagina, and then pFSH was injected twice a day from the evening of Day 6 to the morning of Day 10 with decreasing doses (total of 20 AU; 4, 4, 3, 3, 2, 2, 1, 1 AU/day). On the evening of Day 8, PGF2α (0.5 mg of cloprostenol) was administered. On Day 11, oocytes were aspirated from follicles with ≥5 mm in diameter of the treated donors by OPU (fgt group). The cumulus-oocyte complexes (COC) were cultured in the absence (opu-cont and fgt-cont groups) or presence of 0.1 IU mL−1 FSH (opu-fsh and fgt-fsh groups) or 100 ng mL−1 Areg (opu-areg and fgt-areg groups) in IVM medium (mTCM199 containing 5 mg mL−1 BSA) for 20 to 22 h (1 COC/5 µL, total of 162–171 COC per group), and then co-cultured with 3 × 106 sperm/mL for 6 h. The presumptive zygotes were continued to culture in mCR1aa supplemented with 5% newborn calf serum for 216 h (1 zygote/5 µL) using micro-well culture dishes (Dai-Nippon-Print). When repeating this opu-fgt session in the same cow, an interval at least for 50 days was kept, and the session was performed 28 times. Statistical analysis was carried out by Mann-Whitney’s U-test (between opu and fgt groups) or Steel-Dwass test after Kruskal-Wallis test (among all groups). The number of follicles ≥5 mm increased in the fgt than opu group (17.8 v. 2.9; P < 0.01). The number of COC collected was not different between the opu and fgt groups (23.1 v. 19.6; P > 0.05). The blastocyst formation rate was higher in the fgt than opu group (36.9 v. 23.1%; P < 0.01). Within 6 groups, the blastocyst formation rate was higher in the fgt-fsh (43.3%; P < 0.01) and fgt-areg (39.5%; P < 0.05) groups than the opu-cont (16.3%) group. The rate in the fgt-fsh group was also higher than that in the opu-fsh group (43.3 v. 18.7%; P < 0.01). These results suggested that FGT improved the developmental competence of bovine oocytes, probably through improving the ability of the COC to react against FSH/Areg.

Abstract
AIMS Skin colonization of Staphylococcus spp. critically affects the severity of dermatitis in humans and animals. We examined different types of fatty acid salts for their antibacterial activity against Staphylococcus spp. when used in ultrapure soft water (UPSW). We also evaluated their therapeutic effect on a spontaneous canine model of dermatitis. METHODS AND RESULTS UPSW, in which Ca(++) and Mg(++) were replaced with Na(+) , was generated using a water softener with cation-exchange resin. Staphylococcus aureus (Staph. aureus), Staphylococcus intermedius (Staph. intermedius), and Staphylococcus pseudintermedius (Staph. pseudintermedius) were incubated with various fatty acid salts in distilled water (DW) or UPSW and the number of bacteria was counted. Among the fatty acids, oleic acid salt and linoleic acid (LA) salt reduced the number of these bacteria. Also, UPSW enhanced the antibacterial effect of LA on Staph. spp. In spontaneously developed itchy dermatitis in companion dogs, shampoo treatment with liquid soap containing 10% LA in UPSW improved skin conditions. CONCLUSIONS LA salt showed antibacterial activity against Staph. spp. Treatment with soap containing LA with UPSW reduced clinical conditions in dogs with dermatitis. SIGNIFICANCE AND IMPACT OF THE STUDY Because colonization of Staph. spp. on the skin exacerbates dermatitis, the use of LA-containing soap in UPSW may reduce unpleasant clinical symptoms of the skin.

Abstract
This paper describes the development study of the beam emission spectroscopy (BES) for the turbulent transport study in Heliotron J. Modification of the sightlines (10 × 4 for edge and 10 × 2 for edge) enables us to obtain 2-dimensional BES imaging. The cooling effect on the reduction in the electrical noise of avalanche photodiode (APD) assembly has been investigated using a refrigerant cooling system. When the temperature of the APD element has set to be -20 °C, the electrical noise can be reduced more than 50%. The measurement error of the phase difference in the case of low signal level has been tested by two light-emitting diode lamps. The APD cooling has an effect to improve the measurement error at the low signal level of APD.
