Abstract
Recently, monolayer SnS, a two-dimensional group IV monochalcogenide, was grown on a mica substrate at the micrometer-size scale by the simple physical vapor deposition (PVD), resulting in the successful demonstration of its in-plane room temperature ferroelectricity. However, the reason behind the monolayer growth remains unclear because it had been considered that the SnS growth inevitably results in a multilayer thickness due to the strong interlayer interaction arising from lone pair electrons. Here, we investigate the PVD growth of monolayer SnS from two different feed powders, highly purified SnS and commercial phase-impure SnS. Contrary to expectations, it is suggested that the mica substrate surface is modified by sulfur evaporated from the Sn2S3 contaminant in the as-purchased powder and the lateral growth of monolayer SnS is facilitated due to the enhanced surface diffusion of SnS precursor molecules, unlike the growth from the highly purified powder. This insight provides a guide to identify further controllable growth conditions.

Abstract
Abstract
Background
Because disease progression is so fast in sudden death of acute fulminant myocarditis, damage of myocardial cells is not evident in routine hematoxylin and eosin staining. To understand damage to myocardial cells and the mechanism of sudden death, immunohistochemical staining was performed for two forensic autopsy cases.
Case presentation
The patients were a healthy 5-year-old girl and 8-year-old boy. They suddenly died within 2 days of appearance of flu-like symptoms. An autopsy showed accumulation of yellowish-clear pericardial fluid containing fibrin deposits, fluid blood in the heart, and congestion of visceral organs. Histologically, minor necrosis or degeneration of myocardial cells with mainly lymphocytic infiltration was observed sometimes in tissue sections. Immunohistochemically, positive complement C9 staining and negative sirtuin 1 staining were found. These findings suggested wide damage of myocardial cells, even in regions with no marked changes in myocardial cells with hematoxylin and eosin staining. These areas corresponded to those with strong accumulation of lymphocytes.
Conclusions
Immunohistochemistry for complement C9 and sirtuin 1 might become a new tool for evaluating damage of myocardial cells of fulminant acute myocarditis.

Abstract
PURPOSE The investigators characterized the occurrence of maxillofacial injuries in cyclists and biomechanically analyzed the mechanisms of mandible fractures. METHODS We retrospectively analyzed injury data and performed biomechanical analyses with finite element models. Hospital records from 2011 through 2019 were reviewed to identify patients who had sustained oral and maxillofacial injuries while riding a bicycle. Patients with maxillofacial fractures were compared to those without. Logistic regression analysis was performed to identify which variables were independently associated with the occurrence of maxillofacial fractures. To reconstruct the injury scenario (one in which a person falls from a bicycle and contacts the road surface with their face), computer simulations using The Total Human Model for Safety model were performed. RESULTS The hospital records of 94 patients (62 men, 32 women; 26.1 ± 17.3 years of age) who sustained oral and maxillofacial injuries while riding a bicycle were reviewed. Twenty patients (21.3%) sustained maxillofacial fractures; mandible fractures were most common (16 patients). Patients with maxillofacial fractures were significantly older and had higher severity injuries; however, logistic regression analysis showed that only age was an independent predictor of the occurrence of maxillofacial fracture (odds ratio, 1.03; P = .025). In simulations, higher von Mises stresses were found in the mandible when the cyclist fell with the neck extended and the body horizontal, and consequently, the center of mandibular body strikes the road surface. Contact forces were approximately 8 kN. High tensile stresses occurred laterally and high compressive stresses occurred medially in the mandibular ramus, which indicated that the mandibular ramus deformed in the transverse plane. CONCLUSION Biomechanical analyses show that mandible fractures can occur when a cyclist falls from a bicycle and their lower face strikes the road's surface.

Abstract
BACKGROUND/AIM Because bicyclists and motorcyclists with oral and maxillofacial injuries often suffer from disabilities requiring long-term treatment, reducing the severity of such injuries is a valuable objective for improving these people's quality of life (QOL). The aims of this study were, first, to present the prevalence and patterns of oral and maxillofacial injuries of bicyclists and motorcyclists and to compare the features of these injuries and, second, to determine the factors contributing to long-term hospitalization for these patients and to propose effective preventive measures. MATERIAL AND METHODS This was a single-center retrospective analysis. Hospital records from 2011 through 2018 were reviewed for all patients who had sustained oral and maxillofacial injuries in bicycle or motorcycle collisions and had presented at a university hospital which was the only hospital in the region attended 24 hours per day by oral and maxillofacial surgeons. Characteristics of the oral and maxillofacial injuries, injury severity, and factors influencing the length of hospitalization were examined. RESULTS Records of 130 patients (82 bicyclists and 48 motorcyclists) with a mean age of 28.0 years were analyzed. Thirty-three patients (25.4%) had maxillofacial fractures, with 41 fracture lines while 103 patients (79.2%) had dental injuries and 57 patients (43.8%) had soft-tissue injuries. The distribution and prevalence of oral and maxillofacial injuries were similar for bicyclists and motorcyclists. However, motorcyclists had significantly higher Abbreviated Injury Scale (AIS) scores for facial injuries and the maximum AIS score than did bicyclists. According to a multiple regression analysis, the number of fracture lines and the requirement for intermaxillary fixation were independent factors influencing long-term hospitalization (standard regression coefficients: 6.795 and 6.715, respectively; P < .001). CONCLUSIONS The number of fracture lines and the use of intermaxillary fixation were independent factors influencing long-term hospitalization of both bicyclists and motorcyclists with oral and maxillofacial injuries.

Abstract
Abstract
Background
Polymer- and carrier-free Biolimus-A9-coated stent (DCS) is expected better vascular healing compared with conventional durable polymer drug-eluting stents (DES). Moreover, DCS had been demonstrated in clinical trials to allow one-month short dual antiplatelet therapy, which might achieve sufficient healing at only 1 month after implantation. However, the process of vascular healing after DCS implantation has not been elucidated by angioscopic observation.
Purpose
To evaluate the process of vascular healing at 1 month and 12 months after DCS implantation.
Methods
This study included 57 patients treated with DCS or durable polymer everolimus-eluting stents (EES) in our hospital from April 2017 to April 2019. Firstly, the angioscopic findings of DCS at 1 month (n=16) and 12 months (n=14) after implantation were respectively compared with EES at 12 months after implantation (EES-12, n=35) as a standard healing status of DES. Secondary, angioscopic findings of DCS at 1 month and 12 months after implantation were compared among the serially observed eight patients. Neointimal coverage (NIC) grade, yellow colour grade, and the presence of thrombus were evaluated. NIC grade was classified as grade 0 (no neointimal coverage), grade 1 (struts were bulged into lumen but covered), grade 2 (struts were embedded in the neointima but visible), or grade 3 (struts were fully embedded and invisible). Yellow colour grade was classified as grade 0 (white), grade 1 (light yellow), grade 2 (yellow), or grade 3 (intensive yellow).
Results
At 1 month after DCS implantation, dominant NIC grade was lower (0.3±0.5 vs. 1.5±0.7, p<0.001) and the frequency of thrombus was higher (38% vs. 6%, p=0.008) than EES-12. On the other hands, at 12 months after DCS implantation, dominant NIC grade was higher (2.1±0.6 vs. 1.5±0.7, p=0.013) and the frequency of thrombus was not different (7% vs. 6%, p=1.000) in comparison with EES-12. By serial observation of DCS, dominant NIC grade was higher at 12 months than at 1 month (2.3±0.5 vs. 0.4±0.5, p<0.001), while yellow colour grade (1.0±0.5 vs. 1.5±1.2, p=0.227) and the frequency of thrombus adhesion (0% vs. 38%, p=0.200) were not different.
Conclusion
Compared with EES-12, vascular healing of DCS was inferior at 1 month but superior at 12 months.

Abstract
Abstract
Background
Hemolysis of Impella is known as a major comorbidity and adequate device positioning and optimization of volume status are recommended. However, we have sometimes experienced hemolysis refractory to these adjustments and anatomical feature appears to be crucial in such cases.
Methods
We enrolled 26 patients (median 71 y; BSA 1.6 m2; LVEF 27%) with cardiogenic shock who received Impella insertion from March 2018 to November 2019. The angle of the aortic and mitral annulus which was drawn at the apical 3-chamber view on echocardiography, just before or after Impella insertion was measured (Figure). Hemolytic event was defined as follows; (1) Gross dark red urine and elevation of serum LDH level after initiation of Impella support were seen and subsequently required to lower the support level of Impella under P6. (2) Blood sample data indicating hemolysis (i.e. elevation of LDH level over 1.5 fold of normal range, anemia complicated with decreased haptoglobin, the elevation of total bilirubin level accompanied indirect bilirubin elevation) was found and subsequently required to initiate continuous hemodiafiltration.
Results
The freedom from hemolytic event was significantly lower in the narrow angle group (<126.5 degrees, Figure A) compared with the wide angle group (≥126.5 degrees, Figure B) (18% vs 83%, p<0.0001). The narrow angle was a significant risk factor of hemolytic event with an unadjusted hazard ratio 13.9 (95% confidence interval 2.88–67.2, p=0.0499) and a hazard ratio 15.5 (95% confidence interval 3.15–76.3, p=0.0008) adjusted for lower pulmonary artery pulsatility index, which was another risk factor significant in the univariate analyses. Furthermore, 30-day survival rate was significantly lower in the narrow angle group compared with the wide angle group (63% vs 100%, p=0.0116).
Conclusions
The narrow angle (<126.5 degrees) was an independent risk factor of hemolytic event and 30-day survival was lower compared with the wide angle group.

Abstract
Abstract
Background
Previous studies demonstrated Takotsubo syndrome (TS) was easy provoked by earthquake disaster. However, a previous other regional report demonstrated TS was not increased after 2011 east Japan earthquake disaster. The purpose of this study was to clarify incidence of TS after the earthquake disaster in Iwate prefecture during long term period.
Method
Consecutive hospitalized TS patients were registered during 8 years between 2009 and 2016 in our medical university and five Iwate prefecture hospitals. Moreover, patients were divided into two groups, i.e., those with the inland and those with tsunami-stricken area groups. Prevalence of TS were calculated by standard incidence ratio (SIR) before and after the earthquake disaster. Moreover, long-term prognosis in the both groups was compared using Kaplan-Meier analysis.
Results
A total of 112 TS (male 25 and female 87) were registered from acute coronary syndrome registry in each hospital (n=4,163). Averaged age was 75.3 year-old. A total number of TS just after the two months of the earthquake (March and April 2011) was nine and significance monthly variation was observed comparing with the other months (p=0.029). SIR before and after the disaster is as following Figure. There were no significant differences for long-term prognosis between the two groups (p=0.20).
Conclusion
Incidence of TS was increased in acute phase after east Japan earthquake disaster. However, significance increases were maintained during long-term period, although number of TS was decreased after acute phase. TS is increased not only acute but also chronic phase after the serious earthquake disaster.

Abstract
Purpose Acid-base transport in renal proximal tubules (PTs) is mainly sodium-dependent and conducted in coordination by the apical Na+/H+ exchanger (NHE3), vacuolar H+-adenosine triphosphatase (V-ATPase), and the basolateral Na+/HCO3- cotransporter. V-ATPase on PTs is well-known to play an important role in proton excretion. Recently we reported a stimulatory effect of insulin on these transporters. However, it is unclear whether insulin is involved in acid-base balance in PTs. Thus, we assessed the role of insulin in acid-base balance in PTs. Methods V-ATPase activity was evaluated using freshly isolated PTs obtained from mice, and specific inhibitors were then used to assess the signaling pathways involved in the observed effects. Results V-ATPase activity in PTs was markedly enhanced by insulin, and its activation was completely inhibited by bafilomycin (a V-ATPase-specific inhibitor), Akt inhibitor VIII, and PP242 (an mTORC1/2 inhibitor), but not by rapamycin (an mTORC1 inhibitor). V-ATPase activity was stimulated by 1 nm insulin by approximately 20% above baseline, which was completely suppressed by Akt1/2 inhibitor VIII. PP242 completely suppressed the insulin-mediated V-ATPase stimulation in mouse PTs, whereas rapamycin failed to influence the effect of insulin. Insulin-induced Akt phosphorylation in the mouse renal cortex was completely suppressed by Akt1/2 inhibitor VIII and PP242, but not by rapamycin. Conclusion Our results indicate that stimulation of V-ATPase activity by insulin in PTs is mediated via the Akt2/mTORC2 pathway. These results reveal the mechanism underlying the complex signaling in PT acid-base balance, providing treatment targets for renal disease.

Abstract
Few studies have compared the sensitivities of autopsy and post mortem computed tomography (PMCT) in detecting rib fractures caused by cardiopulmonary resuscitation (CPR). We aimed to compare the characteristics between both modalities for accurately detecting CPR-related rib fractures. This single-centre observational study included adult patients with autopsy records and PMCT scans at our institution from January 2013 to March 2019. CPR-related rib fractures were evaluated using autopsy and PMCT findings. In 62 patients enrolled, 339 rib fractures were detected on autopsy and/or PMCT (222 fractures on both PMCT and autopsy, 69 on PMCT alone, and 50 on autopsy alone). The agreement of detection for both modalities was substantial (kappa coefficient, 0.78). In the logistic regression model, incomplete fractures detected by PMCT and age <75 years were significantly associated with findings that were negative on autopsy but positive on PMCT, while rib number (ribs 1–3 and 7–12) and fracture location (posterolateral and paravertebral) were significantly associated with negative PMCT findings but positive autopsy findings. Autopsy and PMCT showed complementary roles, and are thus necessary in accurately detecting CPR-related rib fractures. Combining both modalities may contribute to improved CPR quality and better understanding of discrepancy in characteristics between the two modalities.

Abstract
AIMS About 80% of cases of locally advanced unresectable thoracic oesophageal squamous cell carcinoma recur within the irradiation fields after chemoradiotherapy. Radiation dose escalation using advanced radiotherapy techniques is expected to improve clinical outcomes by reducing local and regional recurrence. The current study aimed to determine the recommended escalated radiation dose for these patients. MATERIALS AND METHODS Patients with locally advanced unresectable thoracic oesophageal squamous cell carcinoma with good performance status underwent chemoradiotherapy using simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) with elective nodal irradiation. SIB-IMRT was delivered in five fractions per week. The radiation dose to the unresectable gross tumour was escalated from 66 Gy to a planned maximum dose of 72 Gy in 3 Gy increments in a standard 3 + 3 design. The doses to the resectable component, superficial tumours and elective nodal regions were fixed as 60, 51 and 48 Gy, respectively. Cisplatin and 5-fluorouracil were concurrently administered. Dose-limiting toxicity (DLT) was defined as acute grade 3 oesophagitis, grade 2 pneumonitis, grade 2 cardiac toxicity and a failure to complete planned radiotherapy within 60 days. Locoregional control and overall survival were estimated using the Kaplan-Meier method. Nine patients were enrolled. RESULTS DLTs occurred in one of six and two of three patients at doses of 66 and 69 Gy, respectively. All DLTs were grade 3 oesophagitis. The recommended dose was determined as 66 Gy delivered in 30 fractions based on the predefined criteria. With a median follow-up period of 23 months, the 1-year locoregional control and overall survival rates were 67 (95% confidence interval = 19-90) and 78% (95% confidence interval = 36-94), respectively. CONCLUSION The recommended radiation dose in chemoradiotherapy using SIB-IMRT with elective nodal irradiation was 66 Gy delivered in 30 fractions.
