Abstract
Abstract
Background
In recent years it has been attempted to use a distal radial artery (DRA) as a puncture site for cardiac catheterization and intervention. A patency of radial artery is important in hemodialysis patients because the radial artery is source as an arteriovenous shunt. However, the incidence of radial artery occlusion (RAO) is not known after DRA puncture.
Purpose
To compare RAO rates after DRA puncture between dialysis and non-dialysis patients.
Method
This was retrospective, observational and single center study. All consecutive 1,533 patients undergoing DRA puncture were analyzed. The primary endpoint is RAO rates. The secondary endpoint is composite bleeding adverse event rates. These endpoints were evaluated by a vascular echocardiography several hours or the next day after the procedure.
Result
Among 1,533 patients, 26 were dialysis patients and 1,504 were non-dialysis patients. 1,386 people (90.5%) succeeded in puncture. Radial artery occlusion occurred in 7 patients (0.4%), all of whom were non-dialysis patients. There was no significant difference of RAO rate in dialysis patients and non-dialysis patients.
Conclusion
When performing DRA puncture, the probability of radial artery occlusion is not higher in dialysis patients than non-dialysis patients. The DRA puncture may be one of the option as puncture site even in dialysis patients.

Abstract
Postural tachycardia syndrome (POTS) can cause orthostatic headache. However, it is difficult to differentiate POTS from spontaneous intracranial hypotension (SIH) caused by cerebrospinal fluid (CSF) leaks. We herein report a 53-year-old woman who presented with SIH associated with POTS. A cervicothoracic and lumbar epidural blood patch rapidly improved not only the headache but also the orthostatic tachycardia, suggesting POTS secondary to SIH. This case suggests that a CSF leak can cause secondary POTS. Therefore, POTS should be considered in patients with orthostatic headaches, even in the presence of a CSF leak.

Abstract
The potential of genomic selection (GS) is currently being evaluated for fruit breeding. GS models are usually constructed based on information from both the genotype and phenotype of population. However, information from phenotyped but non-genotyped relatives can also be used to construct GS models, and this additional information can improve their accuracy. In the present study, we evaluated the utility of single-step genomic best linear unbiased prediction (ssGBLUP) in citrus breeding, which is a genomic prediction method that combines the kinship information from genotyped and non-genotyped relatives into a single relationship matrix for a mixed model to apply GS. Fruit weight, sugar content, and acid content of 1,935 citrus individuals, of which 483 had genotype data of 2,354 genome-wide single nucleotide polymorphisms, were evaluated from 2009–2012. The prediction accuracy of ssGBLUP for genotyped individuals was similar to or higher than that of usual genomic best linear unbiased prediction method using only genotyped individuals, especially for sugar content. Therefore, ssGBLUP could yield higher accuracy in genotyped individuals by adding information from non-genotyped relatives. The prediction accuracy of ssGBLUP for non-genotyped individuals was also slightly higher than that of conventional best linear unbiased prediction method using pedigree information. This indicates that ssGBLUP can enhance prediction accuracy of breeding values for non-genotyped individuals using genomic information of genotyped relatives. These results demonstrate the potential of ssGBLUP for fruit breeding, including citrus.

Abstract
Catheter ablation for atrial fibrillation creates an iatrogenic atrial septal defect by transseptal puncture, which may produce a transient right-to-left shunt. We encountered a 44-year-old man who presented with de novo migraine-like headache after cryoballoon ablation for atrial fibrillation. On reviewing the literature, we found additional cases in which migraine-like headache occurred within one week after the procedure and spontaneously within three months. We should recognize migraine-like headache as a potential complication of catheter ablation.

Abstract
An 85-year-old woman hospitalized for rehabilitation after cerebral infarction developed persistent bloody diarrhea and was transferred to our hospital (day 1). Contrast-enhanced computed tomography of the abdomen showed edematous thickening extending from the left side of the transverse colon to the rectum, with decreased mucosal enhancement. She was diagnosed with ischemic enteritis. She fasted and was treated with fluids and antibiotics. The bloody diarrhea stopped, and she was restarted on the direct oral anticoagulant (DOAC) edoxaban on day 5. Endoscopy on day 11 showed linear ulceration and severe mucosal edema in the rectum. The diarrhea was persistent, so fasting and fluid therapy were continued. A blood test on day 18 showed significant prolongation of the prothrombin time (≥100 s), International Normalized Ratio (14.03), and activated partial thromboplastin time (87.5 s), as well as a significant increase in protein induced by vitamin K absence-II (12,469 mAU/mL). Her condition was diagnosed as a coagulation abnormality due to vitamin-K deficiency. A vitamin-K preparation was administered immediately, and her coagulation abnormality improved rapidly. In general, DOACs do not require routine monitoring with blood tests. However, frequent monitoring of the coagulation function is required in fasting patients on DOACs because acute coagulation abnormalities can be induced rapidly by vitamin-K deficiency. Given that non-valvular atrial fibrillation and ischemic enteritis are among the most prevalent diseases affecting older people, the likelihood of encountering these diseases in daily clinical practice will increase with the aging of the population. We herein report this instructive case suggesting that a severe coagulation abnormality may develop during treatment for ischemic enteritis in older people taking a DOAC.

Abstract
This study evaluated the effects of cryopreservation by slow freezing on the mitochondrial function, DNA integrity, and developmental ability of bovine embryos and examined whether resveratrol treatment of the frozen-thawed blastocysts improved embryonic viability. In vitro produced bovine embryos were subjected to slow freezing. After thawing, the ATP content and mitochondrial DNA integrity (mtDNA), determined by real-time PCR targeting short and long mitochondrial sequences, was found to be lower in frozen-thawed embryos than in fresh embryos, and mtDNA copy number was significantly reduced during the 24-hr incubation post warming. Furthermore, immunostaining against double-strand DNA revealed DNA damage in frozen-thawed embryos. When frozen-thawed embryos were incubated in the medium containing 0.5 µM resveratrol, SIRT1 expression, and survival rate of the embryos significantly improved compared with the vehicle-treated embryos. In addition, cell-free mtDNA content in medium was higher in case of resveratrol-treated embryos than of vehicle-treated embryos. In conclusion, slow freezing affects mitochondrial integrity and function in the blastocysts. In the frozen-thawed embryos, mitochondria were removed during post-thawing incubation and resveratrol enhanced the process, resulting in improved survivability of the embryos.

Abstract
Amino acids have emerged as novel biomarkers for predicting type 2 diabetes (T2D), but the epidemiologic data linking circulating amino acid profiles with T2D are sparse in Asian populations. We conducted a nested case-control study within a cohort of 4,754 nondiabetic Japanese employees who attended a comprehensive health checkup in 2008-2009 and agreed to provide blood samples. During a 5-year follow-up, incident T2D cases were ascertained based on plasma glucose, glycated hemoglobin, and self-report. Two controls matched to each case on sex, age, and the date of serum sampling were randomly selected by using density sampling, resulting in 284 cases and 560 controls with amino acid measures. High concentrations of valine, leucine, isoleucine, phenylalanine, tyrosine, alanine, glutamate, ornithine, and lysine were associated with an increased risk of incident T2D, in a linear manner. High glutamine concentrations were associated with a decreased risk of incident T2D. Further adjustment for the homeostasis model assessment of insulin resistance attenuated these associations. Overall, these amino acids may be novel useful biomarkers in the identification of people at risk of T2D before overt symptoms. Insulin resistance may account for or mediate the relationship between these amino acids and risk of incident T2D.

Abstract
Tritium dating requires a good understanding of the tritium and water inputs into hydrologic systems, including their main trends due to latitudinal, seasonal and altitudinal effects. Although tritium reached ambient levels at the end of the 20th century, tritium released from nuclear facilities and bomb tests since then has the potential to confound use of tritium for age dating. We therefore collected precipitation and snowpack samples for tritium analysis to confirm that tritium levels in Japanese precipitation had not exceeded ambient levels following the North Korean nuclear tests in January 6th 2016 and September 3rd 2017. As the result, the highest tritium concentration was 5.52(±0.27)TU at samples collected from January 8 to 11th at one Honshu and four Hokkaido locations and samples collected at six Honshu locations had 8.01(±1.5)TU from September 6 to 19th 2017. Confirming ambient tritium concentrations after both events we investigated the latitude tritium effect at selected coastal stations in Asia, indicating a break of latitude trend around Tokyo area, and established the latitude scaling factors to the north and south of the Tokyo area data. The seasonal trend was investigated during the winter-spring 2016 in precipitation samples confirming the higher spring tritium compared with winter continental tritium values. The altitude effect on tritium and stable (18O and 2H) isotopes was observed in Hokkaido snowpack, which had tritium concentrations ranging between 4.08 and 5.93 TU during March-April, and demonstrated two trends for western and central Hokkaido mountain ranges. Using established latitude and altitude scaling factors with the long-term continuous time-series of monthly Tokyo area tritium we estimated the annual weighted tritium at 110 meteorological stations in Japan with monthly precipitation demonstrating the applicability of this approach for future tritium-tracer studies across Asia.

Abstract
We report the case of a 46-year-old man with hemicrania continua presenting as exacerbations mimicking trigeminal neuralgia. The patient was tentatively diagnosed with trigeminal neuralgia, and treatment with various combinations of drugs was performed after the onset of pain. However, when the condition of the patient did not improve, we suspected hemicrania continua, and treatment with indomethacin was initiated. There was a marked alleviation of his pain within 24 hours. Thus, clinicians should be aware that the duration and frequency of exacerbations of hemicrania continua are variable.

Abstract
Abstract
Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a frequent side-effect of taxanes which play a central role in the treatment of breast cancer. CIPN can negatively influence long-term quality of life, warranting the development of effective prevention strategies. This study investigates the efficacy of frozen gloves and socks (FGS) in reducing the incidence and severity of nab-paclitaxel-induced peripheral neuropathy. Endpoints were evaluated using both clinician and patient reports.
Methods: This is a multicenter phase II single arm trial study of the effects of FGS for advanced or metastatic breast cancer patients receiving nab-paclitaxel (260 mg/m2) every 3 weeks. Patients wore FGS on their diseased side hand and foot for 60 min during infusion. The other side acted as the untreated control. CIPN was assessed using Patient Neurotoxicity Questionnaire (PNQ), PRO-CTCAE and CTCAE at baseline and every cycle of nab-paclitaxel. The primary endpoint was the incidence of CIPN assessed by PNQ (grade C or higher) after receipt of up to 4 cycles of nab-paclitaxel.
Results: Between September 2012 and January 2015, 50 patients from 16 sites were enrolled in this study. Of 50 patients, 27 (54%) received at least 4 cycles of nab-paclitaxel. There was a trend for the incidence of CIPN assessed by PNQ and PRO-CTCAE to be lower in the intervention side than in the control side, although this difference was not statistically significant. The incidence of CIPN assessed by CTCAE was significantly lower in the treated hand (Table).
Conclusions: Among breast cancer patients who received nab-paclitaxel, FGS produced favorable effects as detected by reduced clinician-reported CTCAE grades for CIPN, although the study did not detect differences in self-reported symptoms of CIPN using PRO-CTCAE or PNQ. Clinical trial information: UMIN000007907.

Abstract
AIM To evaluate the image quality of bone-vessel fused volume-rendering (VR) images reconstructed by three-dimensional "black bone" magnetic resonance imaging (MRI) based on the fast imaging employing steady-state acquisition cycled phases (FIESTA-C) sequence and time-of-flight magnetic resonance angiography (TOF-MRA). MATERIALS AND METHODS Seventeen patients were analysed in this retrospective study. All patients underwent both MRI techniques including FIESTA-C and TOF-MRA and computed tomography angiography (CTA). MRI- and CT-based bone-vessel VR images were reconstructed. Visual depictions of frontal and parietal branches from the superficial temporal artery (STA) were independently scored by three experienced radiological technologists using a four-grade system. RESULTS In the visual evaluation, the scores of the both right and left frontal branches in MRI-based VR image were significantly larger those at CT (p<0.01, respectively). The scores of both the right and left parietal branches tended to be larger in MRI-based than that in CT-based VR imaging, but were not significantly so (p=0.06, 0.13 respectively). In the interobserver agreement analysis, κ values were all good (range: 0.6-0.76) for STA branch evaluation in MRI-based VR images. CONCLUSION MRI bone-vessel fused VR imaging can non-invasively depict STA frontal branches with better visibility compared to the CT-based VR imaging. This technique may be useful for the preoperative evaluation of donor branches for STA-middle cerebral artery bypass surgery.

Abstract
AIM As the number of aged stroke patients increases in Japan, the proportion of older patients who receive recombinant tissue plasminogen activator (rt-PA, 0.6 mg/kg) is also rising. However, the Japanese stroke guideline indicates that rt-PA therapy must be administered very carefully in older patients (i.e. ≥81 years of age) because of serious complications after the therapy. We retrospectively assessed the clinical outcomes of rt-PA therapy in older patients. METHODS This study included 321 patients who received rt-PA therapy for acute cerebral infarction at our hospital between April 2007 and April 2017. The outcomes (modified Rankin Scale [mRS] score at 3 months after treatment) and symptomatic intracerebral hemorrhaging (sICH) were compared and analyzed between patients ≥81 years of age (group A) and those <81 years of age (group B). In addition, propensity score matching was performed for the factors shown to have significant differences by a univariate analysis in order to adjust for confounding factors, and the outcomes were compared. RESULTS There were 58 patients in group A (18.1%) and 263 patients in group B (81.9%). The rate of favorable outcomes (mRS 0-1) was lower in group A (12.1%) than in group B (44.1%) (P<0.01). The mortality rate was higher in group A (17.2%) than in group B (4.6%) (P=0.002). No marked differences were observed between the 2 groups regarding the rate of sICH (group A, 3.4%; group B, 3.0%; P=1.00). After propensity score matching, the proportion of patients with favorable outcomes was significantly lower in group A (13.2%) than in group B (36.8%) (P=0.032). There were no marked differences in the mortality rates between the groups (group A, 17.2%; group B, 4.6%) (P=0.200), and no patients in either group had sICH. CONCLUSION No marked differences in the incidence of ICH were observed between the older and younger groups receiving intravenous rt-PA therapy. However, in terms of efficacy, the proportion of patients with favorable outcomes was significantly lower in the older group than in the younger group.

Abstract
Grain-filling ability is one of the factors that controls grain yield in rice (Oryza sativa L.). We developed a method for describing grain weight distribution, which is the probability density function of single grain weight in a panicle, using 128 Japanese rice varieties. With this method, we quantitively analyzed genotypic differences in grain-filling ability and used the grain weight distribution parameters for genomic prediction subject to genetic improvement in grain yield in rice. The novel description method could represent the observed grain weight distribution with five genotype-specific parameters of a mixture of two gamma distributions. The estimated genotype-specific parameters representing the proportion of filled grains had applicability to explain the grain filling ability of genotypes comparable to that of sink-filling rate and the conventionally measured proportion of filled grains, which suggested the efficiency and flexibility of grain weight distribution parameters to handle several genotypes. We revealed that perfectly filled grains have to be prioritized over partially filled grains for the optimum allocation of the source of yield in a panicle, from the analysis for obtaining an ideal shape of grain weight distribution. We conducted genomic prediction of grain weight distribution considering five genotype-specific parameters of the distribution as phenotypes relating to grain filling ability. The proportion of filled grains, average weight of filled grains, and variance of filled grain weight, which were considered to control grain yield to a certain degree, were predicted with accuracies of 0.30, 0.28, and 0.53, respectively. The proposed description method of grain weight distribution facilitated not only the investigation of the optimum allocation of nutrients in a panicle for realizing high grain-filling ability, but also allowed genomic selection of grain weight distribution.

Abstract
Activation of mineralocorticoid receptor (MR) is evoked by aldosterone, and it induces hypertension and cardiovascular disease when it's concomitant with excessive salt loading. We have proposed the notion of "MR-associated hypertension", in which add-on therapy of MR blockers is effective even though serum aldosterone level is within normal range. To elucidate its underlying molecular mechanism, we focused on the effect of epidermal growth factor receptor (EGFR)/extracellular signal-regulated kinase (ERK) activation on MR activity. Epidermal growth factor (EGF) administration increased MR transcriptional activity through EGFR/ERK pathway and increased protein level by counteracting MR ubiquitylation in vitro. EGF administration in vivo also increased MR protein level and target gene expression in kidney, which were decreased by EGFR inhibitor. In addition, the administration of EGFR inhibitor lowered systolic blood pressure and MR activity in DOCA/salt-treated mice. In conclusion, EGFR/ERK pathway activation is considered as one of the underlying mechanisms of aberrant MR activation and EGFR/ERK pathway blockade could be an alternative approach for the prevention of MR-related cardiovascular events.

Abstract
OBJECTIVES The effect of a direct-acting oral anticoagulant (DOAC) dose on intracerebral hemorrhage (ICH) severity and outcome remains unclear. The aim of this study is to clarify the frequency of off-label dosing of DOAC treatments in ICH patients and compare clinical characteristics. PATIENTS AND METHODS We studied 43 patients with ICH who were treated with DOAC for nonvalvular atrial fibrillation before the onset of ICH. DOAC treatments were categorized into three groups based on the following doses: optimal dose, under-dose, and overdose. RESULTS Overall, 31 patients were optimally dosed, 10 were under-dosed, and 2 were overdosed. CHADS2 and CHA2DS2-VASc scores were the highest in the overdose group (median, 4, 6, respectively) and the lowest in the optimal dose group (median, 2, 4, respectively) (p = 0.006, p = 0.005, respectively). ICH severity measured using the National Institutes of Health Stroke Scale scores was the highest in the overdose group (median, 26.5) and the lowest in the under-dose group (median, 6.5) (p = 0.244). Larger initial hematoma volume was observed in the overdose group. The ratio of good outcome (modified Rankin Scale score ≤ 2) was higher in the under-dose group (40%) than the other groups, but this difference was not significant. CONCLUSION Our study shows only a few patients received overdosing of a DOAC before the onset of ICH, and they were associated with poorer functional outcomes. Conversely, under-dosing was associated with better functional outcomes than the other groups.

Abstract
In the breeding of citrus (Citrus spp.), suitable fruit quality is essential for consumer acceptance of new cultivars. To identify parental combinations producing F1 progeny with fruit-quality traits exceeding certain selection criteria, we developed a simple and practical method for predicting multiple-trait segregation in an F1 progeny population. This method uses breeding values of parental genotypes and an additive genetic (co)variance matrix calculated by the best linear unbiased prediction method to construct a model for trait segregation in F1 progeny. To confirm the validity of our proposed method, we calculated the breeding values and additive genetic (co)variances based on phenotypic records on nine fruit-quality traits in 2122 genotypes, and constructed a trait segregation model. Subsequently, we applied the trait segregation model to all pairs of the 2122 genotypes (i.e., 2,252,503 combinations), and predicted the most promising combinations and evaluated their probabilities of producing superior genotypes exceeding the nine fruit-quality traits of satsuma mandarin (Citrus unshiu Marcow.) or ‘Shiranuhi’ (‘Kiyomi’ × ‘Nakano No. 3’ ponkan), two popular citrus cultivars in Japan. We consider these results to be useful not only for selecting good parental combinations for fruit quality or other important traits but also for determining the scale of breeding programs required to achieve specific breeding goals.

Abstract
Breeding of fruit trees is hindered by their large size and long juvenile period. Genome-wide association study (GWAS) and genomic selection (GS) are promising methods for circumventing this hindrance, but preparing new large datasets for these methods may not always be practical. Here, we evaluated the potential of breeding populations evaluated routinely in breeding programs for GWAS and GS. We used a pear parental population of 86 varieties and breeding populations of 765 trees from 16 full-sib families, which were phenotyped for 18 traits and genotyped for 1,506 single nucleotide polymorphisms (SNPs). The power of GWAS and accuracy of genomic prediction were improved when we combined data from the breeding populations and the parental population. The accuracy of genomic prediction was improved further when full-sib data of the target family were available. The results suggest that phenotype data collected in breeding programs can be beneficial for GWAS and GS when they are combined with genome-wide marker data. The potential of GWAS and GS will be further extended if we can build a system for routine collection of the phenotype and marker genotype data for breeding populations.

Abstract
SummaryAn abnormal protein S (PS) was found in a Japanese family with a high incidence of thrombosis. The proband is a woman who was born in Tokushima Prefecture. She had superior sagittal sinus thrombosis, thrombophlebitis of the left leg, and thrombosis of the placenta. She had a normal plasma level of free PS antigen but decreased PS activity. Her mother and aunt also had thrombophlebitis of the leg, and together with four other family members also showed a normal level but decreased activity of PS. This suggests that hereditary dysfunction of PS is inherited in this family as an autosomal dominant trait. The proband’s PS appears to have a slightly higher molecular weight than normal PS both in the intact and modified form, suggesting that it has a molecular defect on the carboxyl-terminal side of the thrombin-sensitive site. This abnormal PS with apparently unique characteristics was named PS Tokushima.

Abstract
S-adenosylmethionine is an important compound, because it serves as the methyl donor in most methyl transfer reactions, including methylation of proteins, nucleic acids, and lipids. However, cellular defects in the genetic disruption of S-adenosylmethionine synthesis are not well understood. Here, we report the isolation and characterization of temperature-sensitive mutants of fission yeast S-adenosylmethionine synthetase (Sam1). Levels of S-adenosylmethionine and methylated histone H3 were greatly diminished in sam1 mutants. sam1 mutants stopped proliferating in vegetative culture and arrested specifically in G2 phase without cell elongation. Furthermore, sam1 mutants lost viability during nitrogen starvation-induced G0 phase quiescence. After release from the G0 state, sam1 mutants could neither increase in cell size nor re-initiate DNA replication in the rich medium. Sam1 is thus required for cell growth and proliferation, and maintenance of and exit from quiescence. sam1 mutants lead to broad cellular and drug response defects, as expected, since S. pombe contains more than 90 S-adenosylmethionine-dependent methyltransferases.

Abstract
Cough headache can be a primary benign condition or secondary to underlying etiologies. We herein describe a case of a 52-year-old woman with cough headache that presented as reversible cerebral vasoconstriction syndrome (RCVS). Some cases of RCVS are caused by an aberrant sympathetic response to activities that cause an intracranial pressure surge. Therefore, cough headache should be recognized as a possible presentation of RCVS, even without thunderclap headache or neurological deficits.

Abstract
BACKGROUND Numerous workers have participated in recovery efforts following the accident that occurred at the Tokyo Electric Power Company (TEPCO) Fukushima Daiichi Nuclear Power Plant after the Great East Japan Earthquake. These workers, belonging to various companies, have been engaged in various tasks since the accident. Given the hazards and stress involved in these tasks and the relatively long time required to transport sick or injured workers to medical institutions, it became necessary to quickly implement a more stringent management program for fitness for duty than in ordinary work environments. CASE It took considerable time to introduce and improve a fitness-for-duty program because of several concerns. Various efforts were conducted, sometimes triggered by guidance from the Ministry of Health, Labour and Welfare (MHLW), but the implementation of the program was insufficient. In April 2016, a new program was initiated in which all primary contractors confirmed that their subcontractors had achieved five conditions for workers' fitness for duty on the basis of guidance from the MHLW and occupational health experts. TEPCO confirmed that all primary contractors had implemented the program successfully as of the end of November 2016. CONCLUSION Following a disaster, even though the parties concerned understand the necessity of fitness-for-duty programs and that companies in high positions have responsibilities beyond their legal requirements, it is highly possible that they may hesitate to introduce such programs without guidance from the government. It is necessary to prepare a governmental framework and professional resources that introduce these stringent management programs quickly.
