Abstract
This study aimed to determine whether electrical stimulation-based twitch exercise is effective in inhibiting the progression of immobilization-induced muscle fibrosis. 19 Wistar rats were randomly divided into a control group (n=6), an immobilization group (n=6; with immobilization only), and a Belt group (n=7; with immobilization and twitch exercise through the belt electrode device, beginning 2 weeks after immobilization). The bilateral soleus muscles were harvested after the experimental period. The right soleus muscles were used for histological analysis, and the left soleus muscles were used for biochemical and molecular biological analysis. As a result, in the picrosirius red images, the perimysium and endomysium were thicker in both the immobilization and Belt groups compared to the control group. However, the perimysium and endomysium thickening were suppressed in the Belt group. The hydroxyproline content and alpha-SMA, TGF-beta1, and HIF-1alpha mRNA expressions were significantly higher in the immobilization and belt groups than in the control group. These expressions were significantly lower in the Belt group than in the immobilization group. The capillary-to-myofiber ratio and the mRNA expressions of VEGF and PGC-1alpha were significantly lower in the immobilization and belt groups than in the control group, these were significantly higher in the Belt group than in the immobilization group. From these results, Electrical stimulation-based twitch exercise using the belt electrode device may prevent the progression of immobilization-induced muscle fibrosis caused by downregulating PGC-1alpha/VEGF pathway, we surmised that this intervention strategy might be effective against the progression of muscle contracture. Keywords: Immobilization, Skeletal muscle, Fibrosis, Electrical stimulation-based twitch exercise, PGC-1alpha/VEGF pathway.

Abstract
PURPOSE/OBJECTIVE(S) The current study aims to propose a nomogram-based 2- and 3-years survival prediction model for esophageal squamous cell carcinoma treated by definitive radiotherapy using pretreatment computed tomography (CT), positron emission tomography (FDG PET) radiomic features and dosiomics features in addition to the common clinical factors using multi-institution data. MATERIALS/METHODS Data of 112 patients from one institution and 28 patients from the other institution were retrospectively collected. Radiomics and dosiomics features were extracted using five segmentations on CT and PET images and dose distribution. The least absolute shrinkage and selection operator (LASSO) with logistic regression was used to select radiomics and dosiomics features by calculating the radiomics and dosiomics scores (Rad-score and Dos-score), respectively, in the training model. The predictive clinical factors, Rad-score, and Dos-score were identified to develop a nomogram model. RESULTS We extracted 15219 features from the radiomics and dosiomics analysis. By LASSO Cox regression analysis, 13 CT-based radiomics features, 11 PET-based radiomics features, and 19 dosiomics features were selected. Clinical factors of T-stage, N-stage, and clinical stage were selected as significant prognostic factors by univariate Cox regression analysis. A predictive nomogram for prognosis in was established using these factors. In the external validation cohort, the C-index of the combined model of CT-based radiomics, PET-based radiomics, and dosiomics features with clinical factors were 0.74, 0.82, and 0.92, respectively. Moreover, we divided the cohort into high-risk and low-risk groups using the median nomogram score. Significant differences in overall survival (OS) in the combine model of CT-based radiomics, PET-based radiomics, and dosiomics features with clinical factors were observed between the high-risk and low-risk groups (P = 0.019, P = 0.038, and 0.014, respectively). CONCLUSION The current study established and validated 2- and 3-year survival prediction models based on radiomics and dosiomics features with clinical factors. The prediction model with dosiomics analysis could better predict OS than CT- and PET-based radiomics analysis in esophageal cancer patients treated with radiotherapy.

Abstract
PURPOSE/OBJECTIVE(S) The effectiveness of stereotactic body radiation therapy (SBRT) for hepatocellular carcinoma (HCC) has been shown in many studies and its therapeutic effect is similar to radiofrequency ablation (RFA). However, many of these studies were done in combination with transcatheter chemoembolization (TACE), for recurrent HCC, or on a small scale. To better understand the specific outcomes of SBRT for HCC, we conducted a multicenter retrospective analysis of SBRT for previously untreated initial HCC at Japanese Society of Clinical Oncology (JCOG) member hospitals. MATERIALS/METHODS Patientswho underwent SBRT for HCC at JCOG member hospitals between July 2013 and December 2017 and met the following eligibility criteria were included: (1) initial HCC; (2) ≤ 3 nodules, ≤ 5 cm in diameter; (3) a Child-Pugh (CP) score of A or B; and (4) unsuitability for or refusal of standard treatment, such as surgery, transplantation, RFA and TACE. We evaluated the overall survival (OS), recurrence-free survival (RFS) which was defined as the first instance of intra-hepatic recurrence after SBRT, disease-specific survival (DSS) using Kaplan-Meier analysis. Using Grey's test, patients who died of other diseases were analyzed as competing risks to estimate the cumulative incidence of local recurrence (CLR). Adverse events directly related to SBRT also analyzed using Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0). RESULTS Seventy-three patients with 79 lesions from 14 hospitals were analyzed. The median age was 77 years (range; 50-89 years), and the median tumor size was 23 mm (range; 6-50 mm). The median radiation dose was 40 Gy (range; 35-60 Gy) in five fractions (range; 4-8). The median follow-up period was 45 months (range; 0-103 months). There were three cases where follow-up was not possible due to unexpected events unrelated to SBRT, while the remaining 70 patients were successfully followed for at least six months. The 2 and 3year OS, RFS, DSS, and CLR rates were 84.3% (95% CI: 75.8-92.8%) and 69.9% (95% CI: 58.7-81%), 67.5% (95% CI: 56.0-79.0%) and 57.9% (95% CI: 45.2-70.5%), 95.1% (95% CI:89.7-100%)/87.6% (95% CI:78.8-96.3%), and 11.4% (95% CI: 5.3-20.0%) and 20.0% (95% CI: 11.2-30.5%), respectively. Four cases (5.5%) of adverse events of grade 3 or higher were reported: one case of grade 3 laboratory toxicities, one case of grade 3 liver failure, one case of grade 3 portal tumor thrombosis, and one case of grade 4 duodenal ulcer. No grade 5 toxicities were observed. CONCLUSION The results of our study demonstrate that SBRT for HCC is highly effective in achieving local control and is safe to administer. In addition, survival outcomes are favorable. SBRT is a promising treatment modality, especially for small HCCs for that is not suitable for standard treatment.

Abstract
Betacoronaviruses, containing sarbecoviruses such as severe acute respiratory syndrome coronaviruses (SARS-CoV) and merbecovirus such as Middle East respiratory syndrome coronavirus (MERS-CoV), caused three human outbreaks in the past 2 decades; in particular, SARS-CoV-2 has caused the coronavirus disease 2019 pandemic. Since the ancestor of betacoronaviruses originated from wild bats, unidentified bat betacoronaviruses are presumed to be transmitted to humans in the future. In this study, we detected novel bat merbecoviruses from Vespertilio sinensis and Eptesicus japonensis, belonging to the family Vespertilionidae, in Japan. We found that these merbecoviruses were phylogenetically most closely related to the those previously detected in China. Alignment of the predicted receptor-binding motif on the spike proteins indicated that the Japanese bat merbecoviruses did not possess the specific amino acid residues that could be responsible for binding of MERS-CoV to the human dipeptidyl peptidase-4 receptor, which is unlikely to infect humans. This study demonstrated that bat merbecoviruses are widely conserved in multiple bat species of Vespertilionidae in East Asia, emphasizing the need for extensive epidemiological and biological studies on bat betacoronaviruses to facilitate the risk assessment of their spillover potential to humans.

Abstract
Cerebellar-brain inhibition (CBI) is a transcranial magnetic stimulation (TMS) paradigm indexing excitability of cerebellar projections to motor cortex (M1). Stimulation involved with CBI is often considered to be uncomfortable, and alternative ways to index connectivity between cerebellum and the cortex would be valuable. We therefore sought to assess the utility of electroencephalography in conjunction with TMS (combined TMS-EEG) to record the response to CBI. A total of 33 volunteers (25.7 ± 4.9 years, 20 females) participated across three experiments. These investigated EEG responses to CBI induced with a figure-of-eight (F8; experiment 1) or double cone (DC; experiment 2) conditioning coil over cerebellum, in addition to multisensory sham stimulation (experiment 3). Both F8 and DC coils suppressed early TMS-evoked EEG potentials (TEPs) produced by TMS to M1 (P < 0.05). Furthermore, the TEP produced by CBI stimulation was related to the motor inhibitory response to CBI recorded in a hand muscle (P < 0.05), but only when using the DC coil. Multisensory sham stimulation failed to modify the M1 TEP. Cerebellar conditioning produced changes in the M1 TEP that were not apparent following sham stimulation, and that were related to the motor inhibitory effects of CBI. Our findings therefore suggest that it is possible to index the response to CBI using TMS-EEG. In addition, while both F8 and DC coils appear to recruit cerebellar projections, the nature of these may be different.

Abstract
This study investigated the effects of wheel-running using the upper limbs following immobilization after inducing arthritis in the knees of rats. Forty male Wistar rats (aged 8 weeks) divided into four groups randomly: arthritis (AR), immobilization after arthritis (Im), wheel-running exercise with the upper limbs following immobilization after arthritis induction (Im+Ex) and sham arthritis induction (Con). The knee joints of the Im and Im+Ex groups were immobilized with a cast for 4 weeks. In the Im+Ex group, wheel-running exercise was administered for 60 min/day (5 times/week). The swelling and the pressure pain threshold (PPT) of the knee joint were evaluated for observing the condition of inflammatory symptoms in affected area, and the paw withdraw response (PWR) was evaluated for observing the condition of secondary hyperalgesia in distant area. Especially, in order to evaluate histological inflammation in the knee joint, the number of macrophage (CD68-positive cells) in the synovium was examined. The expression of calcitonin gene-related peptide (CGRP) in the spinal dorsal horn (L2-3 and L4-5) was examined to evaluate central sensitization. The Im+Ex group showed a significantly better recovery than the Im group in the swelling, PPTs, and PWRs. Additionally, CGRP expression of the spinal dorsal horn (L2-3 and L4-5) in the Im+Ex group was significantly decreased compared with the Im group. According to the results, upper limb exercise can decrease pain in the affected area, reduce hyperalgesia in distant areas, and suppress the central sensitization in the spinal dorsal horn by triggering exercise-induced hypoalgesia (EIH).

Abstract
Sofosbuvir plus ledipasvir (SOF-LDV) combination therapy is a promising therapy for post-transplant hepatitis C virus (HCV) reinfection. It is known that gastric pH elevation induces lower absorption of ledipasvir; therefore, the use of proton pump inhibitors (PPIs) should be considered regarding dose reduction after SOF-LDV therapy induction. Here, we report two patients who developed duodenal ulcers due to the discontinuation of PPIs after the induction of SOF-LDV therapy for post-transplant HCV reinfection. The first patient was a 71-year-old man who had undergone living donor liver transplantation due to HCV-related liver cirrhosis. Lansoprazole, 30 mg daily, was discontinued upon SOF-LDV therapy induction. Seven days after SOF-LDV therapy induction, gastrointestinal endoscopy revealed the presence of a duodenal ulcer. The second patient was a 54-year-old man who had undergone living donor liver transplantation due to HCV-related end-stage liver disease. Similar to the first patient, rabeprazole sodium was discontinued upon the induction of SOF-LDV therapy. Eighteen days after SOF-LDV therapy induction, gastrointestinal endoscopy revealed the presence of a duodenal ulcer. In both cases, these duodenal ulcers improved after the resumption of the administration of PPIs, and a sustained virologic response at 12 weeks was achieved by SOF-LDV therapy with PPI use. Thus, PPI use should be continued consistently during SOF-LDV therapy for post-transplant HCV reinfection.

Abstract
Several recent studies have reported that various bat species harbor bat hepatitis E viruses (BatHEV) belonging to the family Hepeviridae, which also contains human hepatitis E virus (HEV). The distribution and ecology of BatHEV are not well known. Here, we collected and screened 81 bat fecal samples from nine bat species in Japan to detect BatHEV RNA by RT-PCR using HEV-specific primers, and detected three positive samples. Sequence and phylogenetic analyses indicated that these three viruses were BatHEVs belonging to genus Orthohepevirus D like other BatHEV strains reported earlier in various countries. These data support the first detection of BatHEVs in Japanese microbats, indicating their wide geographical distribution among multiple bat species.

Abstract
Dental pulp is a potential source of cells that can be used in cell replacement therapy for various nerve disorders, including stroke, spinal cord injury, and peripheral nerve defect. However, the validation of an animal model closely related to humans is needed in translational research. The miniature pig is a suitable experimental model in maxillofacial surgery, because its anatomical structure and size are similar to those of humans. However, the swine tooth is extremely long. The routine closed extraction procedure for harvesting dental pulp tissue causes root fracture. This report describes the details of a surgical procedure for tooth extraction. Four healthy 7-8-month-old male NIBS miniature pigs were used. Two mandibular deciduous right incisors (Di1 and Di2) were extracted in order to obtain dental pulp tissue. Gingival envelope incision with vertical-releasing incision was performed, and a full-thickness mucoperiosteal flap was made. The buccal alveolar bone was exposed and removed by osteotomy. Di1 and Di2 were extracted. Dental pulp tissue was obtained from these extracted teeth by splitting hard tissue. In this procedure, 9.8 ± 2.5 × 10(5) cells were obtained from the mandibular Di1 and Di2 (n = 4).

Abstract
The mycotoxin sterigmatocystin (STC) is produced mainly by some Aspergillus and Penicillium fungi; it naturally contaminates cereals, peanuts, and products derived from these crops, and is both mutagenic and carcinogenic. As an intermediate of aflatoxin (AF) biosynthesis, its structure is similar to that of AF. Although immunoaffinity columns (IACs) are a popular approach to sample clean-up, no IAC is commercially available for STC, but a commercially available IAC for AF shows cross reactivity to STC. We here developed a new method for analyzing STC in grains using such an IAC and liquid chromatography mass spectrometry (LCMS), and validated this method using six different grains. The STC limit of detection (signal-to-noise ratio, S/N = 3) was 2.5 pg (1.0 μg/kg in the product), and the calibration curve was linear in the range of 7.5-375 pg (3.0-150 μg/kg in the product). The within-day recovery of STC from samples spiked with STC at 5.0 and 50 μg/kg was 83.2-102.5% and the RSDr (relative standard deviation of repeatability) of these samples was 1.9-6.5%; the RSDr of STC-pretreated grain samples was 3.1-14.0%. Average recovery of STC from samples spiked with STC in the range of 5.0-100 μg/kg STC was 83.2-102.5%, with an RSDr of 0.24-6.5%; the RSDr of STC-pretreated grain samples was 2.4-14.0%. In an intermediate precision study, the average STC recovery from STC-spiked samples by three analysts was 95.2-107.5%, with RSDRi (intermediate precision) of 4.0-7.1%; the RSDRi of the STC-pretreated samples was 4.8-10.4%. Thus, the proposed method was effective for STC analysis in grains, and holds potential for a novel application of a commercial IAC, intended for AFs, in STC analysis.

Abstract
OBJECTIVE This study retrospectively evaluated the efficacy and toxicity of particle therapy using carbon ions or protons for primary sacral chordomas. METHODS We evaluated 23 patients with primary sacral chordoma treated with carbon ion therapy (CIT) or proton therapy (PT) between July 2005 and June 2011 at the Hyogo Ion Beam Medical Center, Hyogo, Japan. The median patient age was 72 years. 14 patients were treated with 70.4 Gy equivalents (GyE) in 16 fractions and 9 were treated with 70.4 GyE in 32 fractions. CIT was used for 16 patients, and PT was used for 7 patients. RESULTS The median follow-up period was 38 months. At 3 years, local control (LC), overall survival (OS) and progression-free survival (PFS) for all patients were 94%, 83% and 68%, respectively. The log-rank test revealed that male sex was significantly related to better PFS (p=0.029). No other factors, including dose fractionation and ion type, were significant for LC, OS or PFS. In nine patients, ≥ Grade 3 acute dermatitis was observed, and ≥ Grade 3 late toxicities were observed in nine patients. The 32-fraction protocol reduced severe toxicities in both the acute and late phases compared with the 16-fraction protocol. CONCLUSION Particle therapy for patients with sacral chordoma showed favourable LC and OS. Severe toxicities were successfully reduced by modifying the dose fractionation and treatment planning in the later treatment era. Thus, this therapeutic modality should be considered useful and safe. ADVANCES IN KNOWLEDGE This is the first study including both CIT and PT for sacral chordomas.
