Abstract
This paper describes a novel visible light positioning (VLP) system called RefRec+ allowing to estimate the six degree-of-freedom (6DoF) of a smartphone. In most existing VLP systems, their front camera faces multiple light sources installed at different places on a ceiling to detect their direct signals. To overcome the problem of the limited field of views that causes failure to capture required numbers of light sources for positioning and that of the high computational complexity because of image processing to a large-sized pixel data, RefRec+ captures indirect lights from the light sources reflected via a floor. RefRec+ estimates the 2-D position of a point of interest (POI) by calculating the received signal strength of individual light sources using the floor image captured by the camera. Using 2-D positions of multiple POIs and the angle of arrival method, RefRec+ obtains the 6DoF of the smartphone. Several experiments to confirm the performance of RefRec+ were conducted. Experimental results in a room measuring 4.0 m × 4.0 m using nine POIs each of which consists of 32 × 32 pixels in a captured image showed that the absolute errors at the 90th percentile for the 3-D coordinates were 0.2073 m, 0.1713 m, and 0.002464 m along the X, Y, and Z axes, respectively, and for the pitch, roll, and yaw angles were 5.78, 5.69 and 3.96 degrees, respectively.

Abstract
In this paper, we propose a method for recognizing handwritten characters by a finger using acoustic signals. This method is carried out using a smartphone placed on a flat surface, such as a desk. Specifically, this method uses an ultrasonic wave transmitted from the smartphone, which is reflected by the finger, and an audible sound is generated when writing a handwritten character. The proposed method does not require an additional device for handwritten character recognition because it uses the microphone/speaker built into the device. Evaluation results showed that it was able to recognize 36 types of characters with an average accuracy of 77.8% in a low noise environment for 10 subjects. In addition, it was verified that combining an audible sound and an ultrasonic wave in this method achieved higher recognition accuracy than when only an audible sound or an ultrasonic wave was used.

Abstract
Glomerular hyperfiltration is observed in an early stage of kidney diseases including diabetic nephropathy. A better understanding of pathophysiological changes in glomerular hyperfiltration is essential for development of new therapies to prevent kidney disease progression. In this study, we investigated glomerular changes including glomerular filtration rate (GFR) and glomerular size in the Spontaneously Diabetic Torii (SDT) fatty rat, an obese type 2 diabetic model, and we also evaluated pharmacological effects of the sodium glucose cotransporter 2 inhibitor dapagliflozin on the renal lesions. Dapagliflozin was administered to SDT fatty rats from 5 to 17 weeks of age. Blood and urinary biochemical parameters were periodically measured. GFR was determined by transdermal GFR monitor at 16 weeks of age and histopathological analysis was performed at 17 weeks of age. SDT fatty rat developed severe hyperglycemia and exhibited pathophysiological abnormalities in the kidney, such as an increased GFR, glomerular hypertrophy and tissue lesions. Dapagliflozin achieved good glycemic control during the experimental period, inhibited the increase in GFR, and improved histopathological abnormalities in tubules. These results suggest that the SDT fatty rat is a useful model for analyzing the pathogenesis of diabetic nephropathy during its early stage and dapagliflozin improves not only hyperglycemia but also glomerular hyperfiltration and tubule lesions in SDT fatty rat.

Abstract
The aim of this study was to verify the reproducibility and accuracy of preoperative planning in maxilla repositioning surgery performed with the use of computer-aided design/manufacturing technologies and mixed reality surgical navigation, using new registration markers and the HoloLens headset. Eighteen patients with a mean age of 26.0 years were included. Postoperative evaluations were conducted by comparing the preoperative virtual operation three-dimensional image (Tv) with the 1-month postoperative computed tomography image (T1). The three-dimensional surface analysis errors ranged from 79.9% to 97.1%, with an average error of 90.3%. In the point-based analysis, the errors at each point on the XYZ axes were calculated for Tv and T1 in all cases. The median signed value deviation of all calculated points on the XYZ axes was -0.03mm (range -2.93mm to 3.93mm). The median absolute value deviation of all calculated points on the XYZ axes was 0.38mm (range 0mm to 3.93mm). There were no statistically significant differences between any of the points on any of the axes. These values indicate that the method used was able to reproduce the maxilla position with high accuracy.

Abstract
The Linear IFMIF (International Fusion Materials Irradiation Facility) Prototype Accelerator (LIPAc) is aiming at demonstrating the low energy section of a 40 MeV/125 mA IFMIF deuteron accelerator up to 9 MeV with a full beam current in cw operation. For such a high-power beam, the LIPAc injector is required to produce a 100 keV D+ beam with 140 mA and match it for injection into the Radio Frequency Quadrupole (RFQ) accelerator. The injector is designed by CEA-Saclay based on the high intensity light ion source (SILHI). In 2019, the commissioning of the RFQ to demonstrate the D+ beam acceleration at a low duty cycle (0.1%) was conducted. A nominal beam current of 125 mA D+ beam was accelerated up to 5 MeV through the RFQ successfully. The LIPAc injector fully satisfied the requirements for RFQ beam commissioning at the pulse mode.

Abstract
Abstract
Background
Senescence at cellular level develops with various genotoxic stresses and it plays a pivotal role in aging and age-related disorders. Recently, it was shown that elimination of senescent cells, so called “senolysis” has potential to become a next generation therapy for age-related disorders including cardiovascular diseases, pulmonary emphysema, Alzheimer's diseases, etc. However, currently there is no senolytic agent available in clinical settings.
Purpose
Present study was aimed to identify a novel senolytic agent effective for cardiometabolic diseases in compounds already available in clinical settings. Here we demonstrate a compound called “seno-7284” exhibits senolytic effect in murine models of type 2 diabetes, atherosclerosis and progeroid.
Methods
We generated 1) diet-induced obase and diabetic model by imposing a high fat diet for two months, 2) atherosclerosis mice model by imposing western diet to ApoE homozygous knockout mice (ApoE-KO mice) for three months, and 3) Zmpste24 homozygous knockout mice (Zmpste24-KO mice) as a progeroid mice model. We administrated seno-7284 by mixing it into the diet (0.03% w/w). In one, two or four weeks after the administration of seno-7284 to each mice model, we collected tissue samples for further analyses.
Results
Seno-7284 reduced the accumulation of senescent cells in visceral adipose tissue of dietary obese mice as senescence-associated beta-galactosidase (SA-beta-gal) staining exhibits (Figure a). This effect was associated with the suppression in systemic glucose intolerance (Figure b), and adipose tissue inflammation in four weeks after the administration of seno-7284. Administrating seno-7284 for two weeks also reduced accumulation of senescent cells in atherosclerotic lesion in aorta of ApoE-KO mice (Figure c), and inhibited the progression of atherosclerosis (Figure d). Surprisingly, this drug significantly improved the lifespan of Zmpste24-KO mice by administering it from 12 weeks old. Further analysis including RNA-seq or metabolomic analysis suggested that seno-7284 stimulates endogenous senolytic function of NK cells and CD8+ T cells.
Conclusion
Our results indicate that seno-7284 mediates its biological effects by inducing senolysis in some murine aging models. Seno-7284 would become a promising therapeutic agent for age-related cardiometabolic diseases.

Abstract
Abstract
The long-chain branched ethylene-tetrafluoroethylene copolymer (B-ETFE) was synthesized by radical polymerization using ethylene, tetrafluoroethylene, termonomer, and a very small amount of divinyl monomer. We studied melt rheology under shear and elongational flow, and foamability for B-ETFE, comparing with conventional linear ETFE. Addition of a small amount of the divinyl monomer had a considerable impact on the melt rheology of ETFE and its blends. The observed non-linear elongational behavior and emergence of long relaxation time components can be explained by long-chain branching in the modified ETFE. B-ETFE and its blends showed excellent foaming processability: uniform and smaller cell sizes and much higher cell number densities than those of linear ETFE. To the best of our knowledge, this is the first report of the enhancement of the melt rheology of ETFE from the viewpoint of modification of its molecular architecture.

Abstract
We introduce a healing effect of graphene preventing carrier trapping by the defects near the surface of metal halide perovskites.
We herein report that surface modification of metal halide perovskites using graphene would be beneficial to improving the energy conversion efficiencies of perovskite solar cells. The present first-principles calculations on MAPbI3 with a single vacancy created by removing either I, Pb or MA show that the I and Pb vacancies near the surface result in the formation of Pb–Pb and I–I dimers, respectively. They are predicted to yield mid-gap levels, and would degrade the energy conversion efficiency of perovskite solar cells through carrier trapping. The present calculations suggest that when the surface of MAPbI3 is covered with a graphene sheet, the formation of the carrier trapping dimers would be suppressed. The origin of the “healing effect” of graphene on the lattice defect is ascribed to electronic interactions on the surface, which prevent charge localization at the lattice defects beneath the surface.

Abstract
Cathelicidin peptide LL-37 plays an important role in the early host response against invading pathogens via its broad-spectrum anti-microbial activity. In this study, we investigated LL-37 expression in the inflamed mucosa of inflammatory bowel disease (IBD) patients. Furthermore, the regulatory mechanism of LL-37 induction was investigated in human colonic subepithelial myofibroblasts (SEMFs). LL-37 mRNA expression and protein secretion were analysed using real-time polymerase chain reaction and enzyme-linked immunosorbent assay, respectively. Intracellular signalling pathways were analysed using immunoblotting and specific small interference RNA (siRNA). The expression of LL-37 mRNA was increased significantly in the inflamed mucosa of ulcerative colitis and Crohn's disease. The Toll-like receptor (TLR)-3 ligand, polyinosinic-polycytidylic acid (poly(I:C), induced LL-37 mRNA expression and stimulated LL-37 secretion in colonic SEMFs. The transfection of siRNAs specific for intracellular signalling proteins [Toll/IL-1R domain-containing adaptor-inducing interferon (IFN) (TRIF), tumour necrosis factor receptor-associated factor (TRAF)6, transforming growth factor β-activated kinase (TAK)1] suppressed the poly(I:C)-induced LL-37 mRNA expression significantly. Poly(I:C)-induced phosphorylation of mitogen-activated protein kinases (MAPKs) and activated nuclear factor kappa B (NF-κB) and activating factor protein (AP)-1. siRNAs specific for NF-κB and c-Jun inhibited poly(I:C)-induced LL-37 mRNA expression. LL-37 suppressed lipopolysaccharide (LPS)-induced interleukin (IL)-6 and IL-8 expression significantly in colonic SEMFs. The expression of LL-37 was up-regulated in the inflamed mucosa of IBD patients. LL-37 was induced by TLR-3 stimulation and exhibited an anti-microbial effect via interaction with lipopolysaccharide (LPS).

Abstract
Magnetization measurements under pressure reveal that the external hydrostatic pressure significantly increases in the ferrimagnetic transition temperature, Tc, for A2Mn[Mn(CN)6] (A = K, Rb, Cs). In the case of monoclinic A = K and Rb, dTc/dp values are 21.2 and 14.6 K GPa-1, respectively, and Tc increases by 53 and 39%, respectively, from ambient pressure to 1.0 GPa. The cubic A = Cs compound also shows a monotonous increase with an initial rate of 4.22 K GPa-1 and about 11.4 K GPa-1 above 0.6 GPa, and an overall Tc increase by 26% at 1.0 GPa. The increase in Tc is attributed to deformation of the structure such that the MnII-N≡C angle decreases with increasing pressure. The smaller the alkali cation, the greater the decrease in the MnII-N≡C angle induced by pressure and the larger the increase of dTc/dp. This is in accordance with the ambient-pressure structures for A2Mn[Mn(CN)6] (A = K, Rb, Cs), which have decreasing MnII-N≡C angles that correlate to the observed increasing Tcs as K > Rb > Cs. The large increase in Tc for the A = K compound is the highest class among several cyano-bridged metal complexes. The tuning of the transition temperature by such a weak pressure may lead to additional applications such as switching devices.

Abstract
Abstract
Background)
The addition of trastuzumab to standard neoadjuvant chemotherapy (NAC) doubles the pathological complete response (pCR) rate in patients with HER2-positive primary breast cancer. Patients who achieved pCR after NAC with trastuzumab showed a better prognosis compared to those without pCR. However, it is still difficult to predict the likelihood of recurrence after surgery at an individual patient-level. The aim of this study was to develop a mathematical model to predict disease-free survival (DFS) events such as recurrence for patients treated with NAC and trastuzumab. Because brain metastasis (BM) often occurs in HER2-positive cancer patients and it is a particular event for those, we planned to develop a specific model for BM as well.
Patients and Methods)
Data of 776 HER2-positive primary breast cancer patients from the multicenter cohort study (JBCRG-C03) were used in the analysis. All patients had received NAC plus trastuzumab between 2001 and 2010. Two prediction models using a machine learning method (alternating decision tree algorithm) were developed using age, body-mass index, menopausal status, clinical stage, histological type, ER/PgR status, histological/nuclear grade, type of surgery, pathological response, adjuvant radiation therapy, and adjuvant hormonal therapy. The model A (DFS) predicted the probability of any disease recurrence, death by any cause, or secondary malignancy within 5 years after starting treatment. The model B (BM) predicted the probability of occurrence of BM within the 5 years. First, bias-controlled virtual datasets were generated for the training of the models using a resampling method. Second, the models were optimized by cross-validation (CV). Finally, the developed models were validated using the original dataset. The area under the receiver operating characteristics curve (AUC) was calculated to assess the discrimination ability of the models.
Results)
The DFS and BM event was observed in 118 and 30 patients, respectively. The AUC values for the model A and model B were 0.833 (95% CI, 0.798–0.868, P < 0.001) and 0.927 (95% CI, 0.905–0.949, P < 0.001), respectively. The sensitivity and specificity at the cut-off value of 50% were 72.0% and 78.4% for the model A, and 100% and 83.7% for the model B, respectively. Patients predicted as “low-risk” by the model A showed a significantly better 5-year DFS rate than “high-risk” patients (91.2% vs 53.8%, P < 0.001). Patients predicted as “low-risk” by the model B showed a significantly better 5-year BM-free survival rate than “high-risk” patients (100% vs 76.1%, P < 0.001). The discrimination ability of these models were maintained for both ER/PgR-positive and ER/PgR-negative subgroups, and also for both pCR and non-pCR subgroups.
Conclusions)
Our models showed high accuracy for predicting DFS events and BM in HER2-positive primary breast cancer patients treated with NAC and trastuzumab. These two models would help to realize accurate prediction of DFS events and to optimize the postoperative surveillance plan. The identification of high-risk patients for recurrence including BM may be useful for selecting a patient-subpopulation who requires new therapeutic approach.

Abstract
Craniofrontonasal syndrome (CFNS) is a very rare genetic disorder, the common physical malformations of which include coronal synostosis, widely spaced eyes, clefting of the nasal tip, and various skeletal anomalies. Mutations of EFNB1, which encodes a member of the ephrin family of transmembrane ligands for Eph receptor tyrosine kinases, is the cause of CFNS. Although familial CFNS cases have been reported, no studies in the literature describe familial cases of CFNS expressing bilateral cleft lip and palate. Here, we describe a Japanese family with three cases of CFNS expressing bilateral cleft lip and palate.

Abstract
The aim of this study was to evaluate the efficacy of multiple applications of S(+)‐flurbiprofen plaster (SFPP), a novel Nonsteroidal anti‐inflammatory drug (NSAID) patch, for the alleviation of inflammatory pain and edema in rat adjuvant‐induced arthritis (AIA) model as compared to other NSAID patches. The AIA model was induced by the injection of Mycobacterium butyricum and rats were treated with a patch (1.0 cm × 0.88 cm) containing each NSAID (SFP, ketoprofen, loxoprofen, diclofenac, felbinac, flurbiprofen, or indomethacin) applied to the paw for 6 h per day for 5 days. The pain threshold was evaluated using a flexion test of the ankle joint, and the inflamed paw edema was evaluated using a plethysmometer. cyclooxygenase (COX)−1 and COX‐2 inhibition was evaluated using human recombinant proteins. Multiple applications of SFPP exerted a significant analgesic effect from the first day of application as compared to the other NSAID patches. In terms of paw edema, SFPP decreased edema from the second day after application, Multiple applications of SFPP were superior to those of other NSAID patches, in terms of the analgesic effect with multiple applications. These results suggest that SFPP may be a beneficial patch for providing analgesic and anti‐inflammatory effects clinically.

Abstract
BACKGROUND Acid inhibitory effects of proton pump inhibitors (PPIs) are influenced by CYP2C19 genotype. In contrast, the potent acid inhibition of vonoprazan is not influenced by CYP2C19 genotype. AIM To compare the acid inhibitory effects of vonoprazan and esomeprazole in relation to CYP2C19 genotype. METHODS Twenty-eight healthy Japanese volunteers [7 CYP2C19 poor metabolisers (PMs), 11 intermediate metabolisers (IMs) and 10 rapid metabolisers (RMs)] received four different regimens in a randomised crossover manner: (i) vonoprazan 20 mg twice daily (b.d.), (ii) vonoprazan 20 mg daily, (iii) esomeprazole 20 mg b.d. and (iv) esomeprazole 20 mg daily. The timing of each dosing was 1 h before a meal. Twenty-four-hour intragastric pH monitoring was performed on day 7 on each regimen. RESULTS In the overall genotype group, pH ≥4 holding time ratios (pH 4 HTRs) with vonoprazan b.d., vonoprazan daily, esomeprazole b.d. and esomeprazole daily were 100%, 95%, 91%, and 68% respectively. pH 5 HTRs were 99%, 91%, 84% and 54% respectively. Vonoprazan b.d. potently suppressed acid for 24 h, and was significantly superior to other regimens irrespective of CYP2C19 genotype. Vonoprazan daily was equivalent to esomeprazole b.d. in IMs and PMs, but superior in RMs. CYP2C19 genotype-dependent differences were observed in esomeprazole daily but not in vonoprazan b.d. or daily. CONCLUSION Vonoprazan 20 mg b.d. inhibits acid irrespective of CYP2C19 genotype, more potently than esomeprazole 20 mg b.d., pH 4 and 5 holding time ratios reached 100% and 99%, respectively.

Abstract
Preclinical Research This article describes the properties of a novel topical NSAID (Nonsteroidal anti-inflammatory drug) patch, SFPP (S(+)-flurbiprofen plaster), containing the potent cyclooxygenase (COX) inhibitor, S(+)-flurbiprofen (SFP). The present studies were conducted to confirm human COX inhibition and absorption of SFP and to evaluate the analgesic efficacy of SFPP in a rat adjuvant-induced arthritis (AIA) model. COX inhibition by SFP, ketoprofen and loxoprofen was evaluated using human recombinant COX proteins. Absorption of SFPP, ketoprofen and loxoprofen from patches through rat skin was assessed 24 h after application. The AIA model was induced by injecting Mycobacterium tuberculosis followed 20 days later by the evaluation of the prostaglandin PGE2 content of the inflamed paw and the pain threshold. SFP exhibited more potent inhibitory activity against COX-1 (IC50 = 8.97 nM) and COX-2 (IC50 = 2.94 nM) than the other NSAIDs evaluated. Absorption of SFP was 92.9%, greater than that of ketoprofen and loxoprofen from their respective patches. Application of SFPP decreased PGE2 content from 15 min to 6 h and reduced paw hyperalgesia compared with the control, ketoprofen and loxoprofen patches. SFPP showed analgesic efficacy, and was superior to the ketoprofen and loxoprofen patches, which could be through the potent COX inhibitory activity of SFP and greater skin absorption. The results suggested SFPP can be expected to exert analgesic effect clinically.

Abstract
The objective of linear IFMIF prototype accelerator is to demonstrate 125 mA/CW deuterium ion beam acceleration up to 9 MeV. The injector has been developed in CEA Saclay and already demonstrated 140 mA/100 keV deuterium beam [R. Gobin et al., Rev. Sci. Instrum. 85, 02A918 (2014)]. The injector was disassembled and delivered to the International Fusion Energy Research Center in Rokkasho, Japan. After reassembling the injector, commissioning has started in 2014. Up to now, 100 keV/120 mA/CW hydrogen and 100 keV/90 mA/CW deuterium ion beams have been produced stably from a 10 mm diameter extraction aperture with a low beam emittance of 0.21 π mm mrad (rms, normalized). Neutron production by D-D reaction up to 2.4 × 10(9) n/s has been observed in the deuterium operation.

Abstract
Bisphosphonates are widely used in the treatment of osteoporosis and contribute to the reduction of bone fractures. Ibandronate (IBN) is a highly potent, nitrogen-containing bisphosphonate, which is administered orally or intravenously at extended dosing intervals. Vitamin D or active vitamin D3 derivatives are also used in the treatment of osteoporosis, and are often used in combination with other drugs. In this study, we investigated the effect of treatment with the combination of once-monthly s.c. dosing of IBN plus once-daily oral eldecalcitol (ELD), an active vitamin D3 derivative, using aged ovariectomized (OVX) rats. Treatment was started the day after OVX, and analyses were performed 4, 8, and 12 weeks thereafter by determination of bone markers, bone mineral density, biomechanical properties, and histomorphometry. The combination treatment showed a synergistic effect in increasing both lumbar and femoral BMD, and resulted in a significant increase in bone ultimate load. The combination of IBN plus ELD acted synergistically to reduce bone resorption, whereas bone formation did not decrease any more than with monotherapy with either IBN or ELD. Bone formation independent of bone resorption (a process known as 'minimodeling') was not changed in vehicle treated OVX rats despite the increase in bone turnover. ELD upregulated minimodeling, which was however not diminished in the combination treatment. In conclusion, treatment with the combination of IBN plus ELD was beneficial in the treatment of osteoporosis in aged OVX rats. It exhibited a synergistic inhibitory effect on bone resorption and keeps bone formation at the level of sham controls. This uncoupling of bone resorption/bone formation was affected, to some extent, by minimodeling-based bone formation which is independent of bone resorption. This combination regimen which showed synergistic effect on BMD and bone ultimate load without inhibition of bone formation may be beneficial in long-term osteoporosis treatment to prevent bone fractures.

Abstract
OBJECTIVE In this study, we evaluated the effect of hip-joint rotation on the interface pressure over the sacrum and greater trochanter with a new protocol for positioning of bedridden elderly patients. METHOD The interface pressure values over the sacrum and greater trochanter in bedridden patients were evaluated. These were collected in the supine position, 90° lateral position, and 30° and 40° laterally inclined positions with external rotation or neutral positioning of the hip joint. Each interface pressure was assessed with a device measuring pressure distribution, after which, the peak pressure index (PPI) was calculated. RESULTS In the 17 patients examined, the PPI over the sacrum in the supine position was significantly greater than that in other positions. In the 30° and 40° laterally inclined positions, the PPIs over the greater trochanter were significantly lower in the neutral position of the hip joint compared with those in the external rotation position. CONCLUSION Our findings revealed the effects of hip-joint rotation on the interface pressure for the greater trochanter, possibly due to the increased distance between the greater trochanter and the sacrum caused by neutral position of the hip joint. The results demonstrate that it is to best place the hip joint in a neutral position when the legs are in contact with the bed in order to distribute the pressure over the greater trochanter in the 30° and 40° laterally inclined positions. These results can be applied to the clinical setting to improve patient positioning and decrease pressure ulcers.

Abstract
BACKGROUND Bacterial resistance of Helicobacter pylori to antibiotics is increasing and it often leads to failure of antibiotic treatment. A new sitafloxacin-based triple therapy was developed to counter this situation; the fluoroquinolone sitafloxacin has a low minimum inhibitory concentration for H. pylori. AIM To investigate the efficacy in Japanese patients of sitafloxacin-based triple therapy and document its efficacy in relation to anti-microbial susceptibility. METHODS We investigated the efficacy of a 1-week sitafloxicin-based regimen of rabeprazole 10 mg four times daily (q.d.s.), metronidazole 250 mg twice daily (b.d.) and sitafloxacin 100 mg b.d. in 180 H. pylori-positive Japanese patients (first-line treatment: n = 45, second-line; n = 41, third-line: n = 94). At 8 weeks, patients were given the (13) C-urea breath test to assess eradication status. RESULTS Eradication rate was 92.2% [95% confidence interval (CI): 87.3-95.7%, 166/180] in intention-to-treat analysis. Although the eradication rate was higher in patients treated with first-line therapy [45/45 (100%, 95% CI: 83.4-100%)] than in those with second- [38/41 (92.7%, 80.1-98.5%)] or third-line therapy [83/94 (88.3%, 80.0-94.0%)], no significant differences were noted with respect to the number of previous therapy attempts (P = 0.054). Eradication rates in patients infected with sensitive- and resistant strains to metronidazole were 96.6% (28/29) and 96.3% (77/80) (P = 0.941), respectively, while rates were 98.4% (60/61) in sitafloxacin-sensitive and 50.0% (1/2) in sitafloxacin resistant strains (P < 0.001). CONCLUSION Sitofloxacin-based triple therapy with metronidazole b.d. and rabeprazole q.d.s. achieved an eradication rate exceeding 88%, irrespective of eradication history, CYP2C19 genotype, or metronidazole resistance status.

Abstract
Myo-inositol (MI) added into in vitro culture media stimulates blastocyst development of mammals, including cattle (Holm et al. 1999 Theriogenology 52, 683–700), and these stimulatory effects are considered to be exerted via the incorporation of MI into phosphatidylinositol (Hynes et al. 2000 Mol. Reprod. Dev. 55, 265–269). Myo-inositol is catabolized by MI oxygenase (MIOX), which may affect bioavailability of MI for phosphatidylinositol pathway. In the present study, we investigated the expression pattern of MIOX transcripts in bovine pre-implantation embryos and the effects of anti-oxidative vitamins, which promote blastocyst hatching (Ikeda 2014 Reprod. Fertil. Dev. 26, 157), on the expression levels of MIOX in bovine blastocysts in vitro. Cumulus-enclosed oocytes obtained from slaughterhouse bovine ovaries were in vitro-matured for 22 h in modified SOF (mSOF) supplemented with 10% v/v FCS and 0.2 IU mL–1 FSH. After in vitro maturation, the oocytes were subjected to IVF with Percoll gradient-selected sperm in an mSOF-based medium for 20 h. After IVF, presumptive zygotes were freed from cumulus cells and cultured in mSOF up to Day 8 (IVF = Day 0). All cultures were performed at 38.5°C under 5% CO2, 5% O2, and 90% N2. Total RNA was extracted from embryos at the 1-cell, 2-cell, 8-cell, morula, and blastocyst stages (n = 15 × duplicates for each stage) and reverse transcribed to cDNA using oligo (dT) primer in a 31.5 μL reaction volume. Transcripts for MIOX were examined by quantitative reverse transcription-PCR (qRT-PCR) using 1 μL of the cDNA solution and succinate dehydrogenase as a reference gene. Moreover, IVF-derived 8- to 16-cell embryos on Day 3 were cultured in mSOF supplemented with or without a vitamin mix (11 μM a-tocopherol and 9 nM β-carotene) up to Day 8, and blastocysts (n = 10 × 3 replicates) were collected from each treatment. The expression levels of MIOX transcripts in the blastocysts were compared between the treatments by using qRT-PCR. The data were statistically analysed by Mann–Whitney U test. The MIOX transcripts were undetectable at the 1-cell and 2-cell stages and then expressed from the 8-cell stage onward. The vitamin treatment significantly (P < 0.05) decreased the expression level of MIOX in blastocysts. These results suggest that MIOX is one of embryonic-activated genes in bovine pre-implantation embryos, and the level of its expression is regulated by anti-oxidative vitamins. The stimulatory effects of anti-oxidative vitamins on blastocyst development might be in part via the modulation of MI bioavailability.
