Abstract
Globally tropical Scleractinian corals have been a focal point for discussions on the impact of a changing climate on marine ecosystems and biodiversity. Research into tropical Scleractinian corals, particularly the role and breakdown of photoendosymbiosis in response to warming, has been prolific in recent decades. However, research into their subtropical, temperate, cold- and deep-water counterparts, whose number is dominated by corals without photoendosymbiosis, has not been as prolific. Approximately 50% of Scleractinian corals (> 700 species) do not maintain photoendosymbiosis and as such, do not rely upon the products of photosynthesis for homeostasis. Some species also have variable partnerships with photendosymbionts depending on life history and ecological niche. Here we undertake a systematic map of literature on Scleractinian corals without, or with variable, photoendosymbiosis. In doing so we identify 482 publications spanning 5 decades. In mapping research effort, we find publications have been sporadic over time, predominately focusing on a limited number of species, with greater research effort directed towards deep-water species. We find only 141 species have been studied, with approximately 30% of the total identified research effort directed toward a single species, Desmophyllum pertusum, highlighting significant knowledge gaps into Scleractinian diversity. We find similar limitations to studied locations, with 78 identified from the global data, of which only few represent most research outputs. We also identified inconsistencies with terminology used to describe Scleractinia without photoendosymbiosis, likely contributing to difficulties in accounting for their role and contribution to marine ecosystems. We propose that the terminology requires re-evaluation to allow further systematic assessment of literature, and to ensure it's consistent with changes implemented for photoendosymbiotic corals. Finally, we find that knowledge gaps identified over 20 years ago are still present for most aphotoendosymbiotic Scleractinian species, and we show data deficiencies remain regarding their function, biodiversity and the impacts of anthropogenic stressors.

Abstract
This study aimed to investigate adverse reactions to medications administered during palliative care and compare the responses of Board-Certified Pharmacists in Palliative Pharmacy (BCPPP) and non-BCPPP professionals. Methods: This multicentre prospective survey included hospital and community pharmacists who are members of the Japanese Society for Pharmaceutical Palliative Care and Sciences. Study participants included patients who experienced new drug reactions during the study period and responded to the requested survey items. The follow-up period for each eligible patient began on the day the pharmacists initiated the intervention and ended at discharge, death, or after one month of intervention. The primary endpoint was the impact of pharmacist intervention on adverse drug reactions. The pharmacists included in the study evaluated the severity of adverse drug reactions to assess the effect of their intervention using an integrated palliative care outcome scale before and after the intervention. Key findings: During the survey period, 79 adverse drug reaction intervention reports from 69 patients were obtained from 54 pharmacists (28 certified and 26 non-certified). The response rate was 1.62% (54/3,343). The management of palliative pharmacotherapy side effects by BCPPP and non-BCPPP significantly improved the patients' activities of daily living (P < 0.001). The BCPPP group intervened for significantly more patients with adverse drug reactions and overall adverse drug reactions than the non-BCPPP group (P < 0.023 and P < 0.013, respectively). Conclusion: BCPPP interventions can improve symptom management.

Abstract
The stereo-controlled total synthesis of (-)-domoic acid is described. The critical construction of the C1'-C2' Z-configuration was accomplished by taking advantage of an unsaturated lactam structure. The side chain fragment was introduced in the final stages of synthesis through a modified Julia-Kocieński reaction, aiming for its efficient derivatization.

Abstract
Nucleolar stress response is caused by perturbations in ribosome biogenesis, induced by the inhibition of ribosomal RNA processing and synthesis, as well as ribosome assembly. This response induces p53 stabilization and activation via ribosomal protein L11 (RPL11), suppressing tumor progression. However, anticancer agents that kill cells via this mechanism, and their relationship with the therapeutic efficiency of these agents, remain largely unknown. Here, we sought to investigate whether topoisomerase inhibitors can induce nucleolar stress response as they reportedly block ribosomal RNA transcription. Using rhabdomyosarcoma and rhabdoid tumor cell lines that are sensitive to the nucleolar stress response, we evaluated whether nucleolar stress response is associated with sensitivity to topoisomerase inhibitors ellipticine, doxorubicin, etoposide, topotecan, and anthracyclines. Cell proliferation assay indicated that small interfering RNA-mediated RPL11 depletion resulted in decreased sensitivity to topoisomerase inhibitors. Furthermore, the expression of p53 and its downstream target proteins via western blotting showed the suppression of p53 pathway activation upon RPL11 knockdown. These results suggest that the sensitivity of cancer cells to topoisomerase inhibitors is regulated by RPL11-mediated nucleolar stress responses. Thus, RPL11 expression may contribute to the prediction of the therapeutic efficacy of topoisomerase inhibitors and increase their therapeutic effect of topoisomerase inhibitors.

Abstract
Simple Summary Pediatric patients with B-cell precursor acute lymphoblastic leukemia (BCP-ALL) relapse or are refractory to chemotherapy despite the low frequency of TP53 mutations. The nucleolar stress response is one of the mechanisms that activate P53 by ribosomal protein L11 (RPL11). We hypothesized that the lack of nucleolar stress response is related to chemoresistance and relapse in some pediatric BCP-ALL cases. We revealed that clinical BCP-ALL therapeutics, such as 6-mercaptopurine, methotrexate, daunorubicin, and cytarabine, induced the nucleolar stress response, and its treatment susceptibility was dependent on the nucleolar stress response. Furthermore, we observed decreased RPL11 expression at relapse in seven children with BCP-ALL in comparison to that at onset. Our findings provide new insights into the anti-leukemia mechanism in BCP-ALL and multidrug resistance and relapse via the nucleolar stress response, suggesting that the nucleolar stress response may be a potential therapeutic strategy to predict chemosensitivity and improve chemoresistance in pediatric BCP-ALL. Abstract Approximately 20% of pediatric patients with B-cell precursor acute lymphoblastic leukemia (BCP-ALL) relapse or are refractory to chemotherapy despite the low frequency of TP53 mutations. The nucleolar stress response is a P53-activating mechanism via MDM2 inhibition by ribosomal protein L11 (RPL11). We analyzed the role of the nucleolar stress response using BCP-ALL cell lines and patient samples by drug sensitivity tests, Western blotting, and reverse transcription polymerase chain reaction. We revealed that the nucleolar stress response works properly in TP53 wild-type human BCP-ALL cell lines. Next, we found that 6-mercaptopurine, methotrexate, daunorubicin, and cytarabine had anti-leukemic effects via the nucleolar stress response within BCP-ALL treatment. Comparing the samples at onset and relapse in children with BCP-ALL, RPL11 mRNA expression decreased at relapse in seven of nine cases. Furthermore, leukemia cells with relapse acquired resistance to these four drugs and suppressed P53 and RPL11 expression. Our findings suggest that the nucleolar stress response is a novel anti-leukemia mechanism in BCP-ALL. As these four drugs are key therapeutics for BCP-ALL treatment, dysfunction of the nucleolar stress response may be related to clinical relapse or refractoriness. Nucleolar stress response may be a target to predict and improve the chemotherapy effect for pediatric BCP-ALL.

We herein report a 13-year-old boy with a chief complaint of abdominal pain and a palpable mass. Contrast-enhanced computed tomography (CT) scan showed an abdominal bulky tumor involving the ascending colon causing severe stenosis, with multiple abdominal lymph node metastases detected by positron emission tomography (PET)-CT. Laparoscopic radical resection with right hemicolectomy and lymph node dissection was planned. The bulky tumor was dissected from the retroperitoneum and resected en bloc with the right-side colon and omentum. The preoperatively detected metastatic lymph nodes were resected along with the tumor. A 6-cm longitudinal umbilical incision was made, and the huge tumor was removed, with functional end-to-end anastomosis performed for intestinal reconstruction. The pathological diagnosis was Burkitt-like lymphoma with 11q aberration. The postoperative course was uneventful. Laparoscopy-assisted extirpation is feasible for pediatric solid tumors involving other organs, but indications and procedures should be carefully determined based on preoperative imaging, intraoperative findings and surgeon's skills.

Abstract
Drug resistance is a major problem in treatment with nelarabine, and its resolution requires elucidation of the underlying mechanisms. We established two nelarabine-resistant subclones of the human T-cell lymphoblastic leukemia cell line CCRF-CEM. The resistant subclones showed changes in the expression of several genes related to nelarabine intracellular activation and inhibition of apoptosis. Activation of the Akt protein upon nelarabine treatment was observed in both subclones. The combination treatment with nelarabine and PI3K/Akt inhibitors was shown to inhibit cell growth. Cross-resistance was observed with ara-C and not with vincristine, daunorubicin, or etoposide treatment. Thus, changes in the expression of cellular activation-related genes, inhibition of apoptosis, and induction of Akt may be involved in the development of nelarabine resistance in the CCRF-CEM cell model. The use of different classes of chemotherapeutic agents and combination therapy with PI3K/Akt pathway inhibitors may be used to overcome resistance to nelarabine.

Abstract
We report the synthesis of seven-membered iminosugars derived from a 3S-acetamido-4R,5R,6S-trihydroxyazepane scaffold and their evaluation as inhibitors of functionally related exo-N-acetylhexosaminidases including human O-GlcNAcase (OGA), human lysosomal β-hexosaminidase (HexAB), and Escherichia coli NagZ. Capitalizing on the flexibility of azepanes and the active site tolerances of hexosaminidases, we explore the effects of epimerization of stereocenters at C-3, C-5 and C-6 and C-alkylation at the C-2 or C-7 positions. Accordingly, epimerization at C-6 (L-ido) and at C-5 (D-galacto) led to selective HexAB inhibitors whereas introduction of a propyl group at C-7 on the C-3 epimer furnished a potent NagZ inhibitor.

Abstract
It is well known that black and green tea extracts, particularly polyphenols, have antimicrobial activity against various pathogenic microbes including viruses. However, there is limited data on the antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), which emerged rapidly in China in late 2019 and which has been responsible for coronavirus disease 2019 (COVID‐19) pandemic globally. In this study, 20 compounds and three extracts were obtained from black and green tea and found that three tea extracts showed significant antiviral activity against SARS‐CoV‐2, whereby the viral titre decreased about 5 logs TCID50 per ml by 1·375 mg ml−1 black tea extract and two‐fold diluted tea bag infusion obtained from black tea when incubated at 25°C for 10 s. However, when concentrations of black and green tea extracts were equally adjusted to 344 µg ml−1, green tea extracts showed more antiviral activity against SARS‐CoV‐2. This simple and highly respected beverage may be a cheap and widely acceptable means to reduce SARS‐CoV‐2 viral burden in the mouth and upper gastrointestinal and respiratory tracts in developed as well as developing countries.

Abstract
Abstract
Background
The evolutionary conserved NEAT1-MALAT1 gene cluster encounters high interest in cardiovascular medicine and oncology. The cluster generates large primary transcripts which remain nuclear, whereas novel tRNA-like transcripts (mascRNA, menRNA) enzymatically generated from these precursors translocate to the cytosol. We previously found that NEAT1 and MALAT1 deficient mice display accelerated atherosclerosis and vascular inflammation due to immune dysfunctions.
Methods
While the previously investigated mice were deficient in the entire NEAT1 or MALAT1 locus, here we aimed to selectively disrupt only tRNA-like transcripts “menRNA” arising from NEAT1, or “mascRNA” arising from MALAT1. To none of these a biological function has been assigned so far. Both lncRNAs give rise to transcripts of vastly different size (NEAT1: 23kb MENb, 3.7kb MENe, 59nt “menRNA”; MALAT1: 8.3 kb primary, 59nt “mascRNA”), and traditional knockout methods are unable to selectively inactivate one of the small transcripts only. Through CRISPR/Cas9 editing we therefore developed human monocyte-macrophage cell lines with short deletions in the respective tRNA-encoding sequences to disrupt normal menRNA or mascRNA formation, respectively. These editing procedures do not affect transcription of the respective lncRNA parent transcripts, and also not disturb regular formation of the triple-helix structures at their 3'-ends which support stabilization of the respective lncRNAs (Fig. 1).
Results
We found the tRNA-like transcripts menRNA and mascRNA critically influence innate immunity and angiogenesis. In addition to common anomalies resulting from their selective CRISPR-Cas9 mediated deletion (Fig. 1), there are specific disturbances associated with either Δmasc or Δmen cells (Fig. 2).
Both ΔmascRNA and ΔmenRNA human monocytes show profoundly altered ribosomal RNA/protein and tRNA-modifying enzyme expression, display anomalous growth/ angiogenetic factor expression, fundamentally change angiogenetic patterns in co-cultures with human endothelial cells, and have gravely disturbed innate immune responses (LPS, DNA and RNA viruses) (Fig. 1).
CRISPR-engineered ΔmenRNA cells share remakable similarities with human post-MI PBMCs, suggesting the NEAT1-menRNA system may significantly contribute to post-MI residual inflammatory risk despite optimal standard therapy (Fig. 2).
Conclusions
Beyond prior work in knockout mice documenting immune function of the NEAT1-MALAT1 cluster, the current study identifies menRNA and mascRNA as important novel components of human innate immunity with relevance for angiogenetic processes. These data provide a second mechanistic link for the apparent relevance of the NEAT1-MALAT1 gene cluster in cardiovascular and malignant diseases. As prototypes of a novel class of small noncoding RNAs (distinct from miRNAs and siRNAs) they may constitute cytosolic therapeutic targets.

Abstract
Being able to identify trustworthy strangers is a critical social skill. However, whether such impressions are accurate is debatable. Critically, the field currently lacks a quantitative summary of the evidence. To address this gap, we conducted two meta-analyses. We tested whether there is a correlation between perceived and actual trustworthiness across faces, and whether perceivers show above-chance accuracy at assessing trustworthiness. Both meta-analyses revealed significant, modest accuracy (face level, r = .14; perceiver level, r = .27). Perceiver-level effects depended on domain, with aggressiveness and sexual unfaithfulness having stronger effects than agreeableness, criminality, financial reciprocity, and honesty. We also applied research weaving to map the literature, revealing potential biases, including a preponderance of Western studies, a lack of "cross-talk" between research groups, and clarity issues. Overall, this modest accuracy is unlikely to be of practical utility. Moreover, we strongly urge the field to improve reporting standards and generalizability of the results.

Abstract
OBJECTIVE Quasi-moyamoya disease (QMMD) is moyamoya disease (MMD) associated with additional underlying diseases. Although the ring finger protein 213 (RNF213) c.14576G>A mutation is highly correlated with MMD in the Asian population, its relationship to QMMD is unclear. Therefore, in this study the authors sought to investigate the RNF213 c.14576G>A mutation in the genetic diagnosis and classification of QMMD. METHODS This case-control study was conducted among four core hospitals. A screening system for the RNF213 c.14576G>A mutation based on high-resolution melting curve analysis was designed. The prevalence of RNF213 c.14576G>A was investigated in 76 patients with MMD and 10 patients with QMMD. RESULTS There were no significant differences in age, sex, family history, and mode of onset between the two groups. Underlying diseases presenting in patients with QMMD were hyperthyroidism (n = 6), neurofibromatosis type 1 (n = 2), Sjögren's syndrome (n = 1), and meningitis (n =1). The RNF213 c.14576G>A mutation was found in 64 patients (84.2%) with MMD and 8 patients (80%) with QMMD; no significant difference in mutation frequency was observed between cohorts. CONCLUSIONS There are two forms of QMMD, one in which the vascular abnormality is associated with an underlying disease, and the other in which MMD is coincidentally complicated by an unrelated underlying disease. It has been suggested that the presence or absence of the RNF213 c.14576G>A mutation may be useful in distinguishing between these disease types.

Abstract
The core light-harvesting complexes (LH1) in bacteriochlorophyll (BChl) b-containing purple phototrophic bacteria are characterized by a near-infrared absorption maximum around 1010 nm. The determinative cause for this ultra-redshift remains unclear. Here, we present results of circular dichroism (CD) and resonance Raman measurements on the purified LH1 complexes in a reaction center-associated form from a mesophilic and a thermophilic Blastochloris species. Both the LH1 complexes displayed purely positive CD signals for their Qy transitions, in contrast to those of BChl a-containing LH1 complexes. This may reflect differences in the conjugation system of the bacteriochlorin between BChl b and BChl a and/or the differences in the pigment organization between the BChl b- and BChl a-containing LH1 complexes. Resonance Raman spectroscopy revealed remarkably large redshifts of the Raman bands for the BChl b C3-acetyl group, indicating unusually strong hydrogen bonds formed with LH1 polypeptides, results that were verified by a published structure. A linear correlation was found between the redshift of the Raman band for the BChl C3-acetyl group and the change in LH1-Qy transition for all native BChl a- and BChl b-containing LH1 complexes examined. The strong hydrogen bonding and π-π interactions between BChl b and nearby aromatic residues in the LH1 polypeptides, along with the CD results, provide crucial insights into the spectral and structural origins for the ultra-redshift of the long-wavelength absorption maximum of BChl b-containing phototrophs.

Abstract
Abstract
Introduction
Cervical spine (c-spine) injury has a high morbidity and mortality in patients over the age of 65; more than 60% result from falls from standing height (Beedham et al., 2019).
The Canadian Cervical Spine Rule (Stiell et al., 2001) deems that there is a high risk of c-spine fracture if any of the following apply:
The c-spine cannot be cleared clinically if the patient fits any of the above criteria. Imaging should be considered. As a result of recent clinical experiences Trust Guidelines at Stoke Mandeville Hospital now reflect this evidence (Hadley et al., 2019).
Methods
Fifty patients over the age of 65 who had a computerised tomography (CT) head scan in the Emergency Department (ED) following a traumatic head injury were randomly selected over a 1 month period. Cases were checked for examination of c-spine and/or CT c-spine. Results of the first cycle of the audit were presented at an ED Education Meeting. Indications for CT c-spine were displayed in poster format around the ED. Following these interventions, a re-audit was carried out using the same methodology.
Results
In fifty patients aged over 65 attending ED during one month, 16% had a CT c-spine in addition to a CT head. There was documented c-spine examination of 16% of those without CT c-spine on admission. In the re-audit 38% of the fifty patients who had a CT head underwent CT c-spine. In the group that did not have imaging of the c-spine, the proportion with documented cervical spine examination on admission remained the same (16%).
Conclusion
There was a 137.5% increase in the number of patients aged over 65 who appropriately underwent a CT c-spine as per Trust and National guidelines. Simple interventions (staff education and posters within the ED) were sufficient to significantly alter practice. Current trauma triage is not optimal for older patients who are reviewed by more junior doctors, less likely to be transferred to Major Trauma Centres and more likely to die than younger patients with similar injuries (Major Trauma In Older People 2017 Report). An older person’s trauma team in ED with age-appropriate triage would lead to appropriate imaging in a timely fashion, potentially improving the morbidity and mortality of these vulnerable patients.

Abstract
BACKGROUND The prognosis of patients with metastatic Ewing sarcoma family of tumors (ESFT) remains poor. PROCEDURE We retrospectively analyzed 57 patients diagnosed with metastatic ESFT between 2000 and 2018 to identify prognostic and therapeutic factors affecting the clinical outcome. RESULTS The 3-year overall survival (OS) rate of the entire cohort was 46.8% (95% confidence interval [CI], 33.0-59.4%). Treatment-related death was not observed. Multivariate analysis identified stem cell transplantation (SCT), response to first-line chemotherapy, and bone metastasis as independent risk factors for OS. Objective response rate to first-line chemotherapy was 65.1% in the 43 evaluable patients. There was no significant difference in the response to different types of first-line chemotherapy. Among patients with lung metastasis alone, the 3-year OS rate was higher in 13 patients who received local treatment than in four who did not, although the difference was not significant. CONCLUSIONS One possible reason for the high OS rates was the absence of treatment-related mortality even in patients receiving SCT, which could be attributed to advances in the management of post-SCT complications. Novel first-line chemotherapy strategies need to be established to improve the disease status prior to SCT in a higher proportion of patients.

Abstract
Herein, we describe a 13-year-old male adolescent who had chronic thrombocytopenia since infancy. In this case, X-linked thrombocytopenia (XLT) was suspected owing to a family history of chronic thrombocytopenia and small-sized platelets. Moreover, the patient was refractory to immunoglobulin therapy. The Wiskott-Aldrich syndrome protein (WASP) expression analysis revealed a decreased expression. Results showed a missense mutation [c.296A>G (p.Gln99Arg)] in exon 3 of the WASP-interacting protein region. Therefore, a diagnosis of XLT was made. To lift exercise restrictions, we initiated treatment with eltrombopag at a dose of 12.5 µg/day. The platelet count of the patient increased to approximately 50×103/µl after the treatment dose was escalated to 25 µg/day, and bleeding symptoms decreased after the patient resumed exercise. Ultrastructural platelet abnormalities and abnormal platelet aggregation were observed on transmission electron microscopy after the administration of eltrombopag. Therefore, eltrombopag treatment can increase platelet count and reduce bleeding symptoms in patients with XLT.

Abstract
The Japan Atomic Energy Agency (JAEA) started the Research and Development (R&D) to improve nuclear prediction techniques for High Temperature Gas-cooled Reactors (HTGRs). The objectives are to introduce a generalized bias factor method to avoid full mock-up experiment for the first commercial HTGR and to introduce reactor noise analysis to High Temperature Engineering Test Reactor (HTTR) experiment to observe sub-criticality. To achieve the objectives, the reactor core of graphite-moderation system named B7/4”G2/8”p8EUNU+3/8”p38EU(1) was newly composed in the B-rack of Kyoto University Critical Assembly (KUCA). The core is composed of the fuel assembly, driver fuel assembly, graphite reflector, and polyethylene reflector. The fuel assembly is composed of enriched uranium plate, natural uranium plate and graphite plates to realize the average fuel enrichment of HTTR and it’s spectrum. However, driver fuel assembly is necessary to achieve the criticality with the small-sized core. The core plays a role of the reference core of the bias factor method, and the reactor noise was measured to develop the noise analysis scheme. In this study, the overview of the criticality experiments is reported. The reactor configuration with graphite moderation system is rare case in the KUCA experiments, and this experiment is expected to contribute not only for an HTGR development but also for other types of a reactor in the graphite moderation system such as a molten salt reactor development.

Abstract
AIM To evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) for the antenatal diagnosis of placenta accreta spectrum (PAS). MATERIALS AND METHODS Data from 95 patients with placenta previa or low-lying placenta who underwent MRI at Osaka University Hospital for the antenatal diagnosis of PAS between January 2013 and December 2018 were reviewed retrospectively. The antenatal MRI signs suggesting PAS were assessed. Patients were divided into two groups depending on whether they were diagnosed with PAS. Factors that affected PAS diagnosis were identified using multivariate analysis. RESULTS The diagnostic accuracy of MRI for detecting PAS was as follows: 71.4% sensitivity, 96.4% specificity, and area under the curve (AUC) of 0.839 (95% confidence interval [CI]: 0.73-0.91). The diagnostic accuracy was lower in patients with in-vitro fertilisation with embryo transfer (IVF-ET): 22.2% sensitivity, 93.3% specificity, and AUC=0.578 (95% CI: 0.417-0.724). On multivariate analysis, only IVF-ET showed a significant association with false-positive or -negative MRI diagnosis of PAS (adjusted odds ratio: 26.5; 95% CI: 2.42-289.4; p=0.007). CONCLUSION IVF-ET affects the antenatal diagnosis of PAS using MRI.

Abstract
An isolate originally obtained from pond water in Osaka in 1992 and identified as Pythium marsipium, was subsequently classified as Globisporangium marsipium. According to molecular phylogenetic analyses based on the internal transcribed spacer regions of the nuclear ribosomal RNA and mitochondrial cytochrome c oxidase subunit 1 genes, this isolate was shown to represent a new species, described here as G. lacustre sp. nov. In addition, two further new combinations are introduced in Globisporangium as G. camurandrum and G. takayamanum based on their DNA phylogeny.

Abstract
AIM Patient body composition is an important indicator of metabolic status and is associated with cancer progression. Because body composition varies between men and women, we aimed to examine the difference in clinical impact of preoperative body composition according to sex. METHOD We used an integrated dataset of 559 colorectal cancer (CRC) patients. The association between preoperative body composition indices [body mass index (BMI), visceral to subcutaneous fat area ratio (VSR) and skeletal muscle index (SMI)] and patient outcome, clinicopathological factors and preoperative inflammation and nutritional status was analysed, comparing men and women. RESULTS Preoperative low BMI and low SMI in men was significantly associated with unfavourable overall survival (OS) [BMI: hazard ratio (HR) 2.22, 95% CI 1.28-4.14, P = 0.004; SMI: HR 2.54, 95% CI 1.61-4.07, P < 0.001] and high VSR in women was significantly associated with unfavourable OS (HR 1.79, 95% CI 1.03-3.02, P = 0.040). Additionally, low SMI in men was significantly associated with deeper tumour invasion and greater distant metastasis and high VSR in women was significantly associated with advanced age, right-sided tumour, lower total lymphocyte count and lower albumin levels. Interestingly, low BMI in men was significantly associated with deeper tumour invasion, but also with favourable inflammation and nutritional status (lower C-reactive protein and higher albumin). CONCLUSION The clinical impact of preoperative body composition differed between men and women: SMI in men and VSR in women were good prognosticators. Our findings may provide a novel insight for CRC treatment strategies.

Abstract
We report the first case of liver abscess due to Sterigmatomyces halophilus. Because this pathogen grows poorly in culture medium without added salts, it was identified by sequencing analysis targeting the rRNA gene internal transcribed spacer (ITS) region. This method could be useful for pathogens that cannot be cultured using standard methods.

Abstract
Gels are a soft elastic material consisting of a three-dimensional polymer network with nanometer-sized pores and are used in a variety of applications. However, gel networks typically have a substantial level of defects because the network formation reaction proceeds stochastically. In this study, we present a general scheme to fabricate gels with extremely low levels of defects by applying geometric constraints into pregel solution based on the "bond percolation" concept. In the formed gel, stationary laser speckles, which are an indicator of spatial defects, were not observed at all. In addition, we found that the concentration fluctuations of the polymer chains were ergodic across the whole gel network. In such a homogeneous gel, both the spatial and temporal correlations of polymer chains are the same before and after gelation.

Abstract
Abstract
Background
Cancer and cardiovascular disease (CVD) is the most common cause of death in developed countries, and substantial overlap exist in their medical care. However, the detailed and updated information on outcome of cancer patients with cardiovascular disease (CVD), particularly in clinically significant coronary artery disease (CAD) remain unknown.
Purpose
We sought to describe the prevalence and long-term outcomes of cancer patients undergoing percutaneous coronary intervention (PCI), which has become a coronerstone in the management of CVD.
Methods
Patient data extracted from a regional prospectiveprocedure-based multicenter registry for PCI was analyzed. A total of 4,455 patients who underwent PCI at 15 hospitals within metropolitan Tokyo from September 2008 to 2012 were followed for 2 years. “Active” cancer patient was defined as having a history of cancer not cured or in remission. We analyzed in acute and stable presentation.The occurrence of clinical outcomes was assessed via Kaplan-Meier survival curve, and Cox-regression hazard model to adjust for known clinical predictors.
Results
Within the studied patients, 173 (3.9%) had a concomitant “active” cancer at the time of intervention. There was a significant difference between the patients with and without active cancer in each situation. In stable presentation, cancer group were older, lower BMI, frequently had silent ischemia, COPD and cerebrovascular/peripheral disease, and less often had dyslipidemia compared with non-cancer group. In acute presentation, cancer group were older, frequently had COPD, CKD, peripheral disease and history of HF compared with non-cancer group. The prescription rate of RAAS inhibitor was lower in the cancer group than in the non-cancer group in acute presentation. Notably, in both acute and stable presentation, these patients had significantly higher risk of all-cause mortality (HR 8.01: 95%, p<0.001 and HR5.53: 95%, p<0.001, respectively), and they were also at higher risk of major cardo- and cerebrovascular events (MACCE; HR2.38, p<0.001, HR2.33, p=0.001), when referenced to non-cancer patients after 2 year of follow-up.
Conclusion
Cancer patient was present in 3.9% of all PCI patients and was strongly associated with both non-cardiac and cardiac adverse events.

Abstract
Abstract
Background
Heart failure (HF) is a common complication within the clinical spectrum of hypertrophic cardiomyopathy (HCM). HCM-related HF is recognized to be multifactorial, including outflow obstruction, diastolic dysfunction, or progression to end-stage; however, prognostic predictors of HF events are not fully understood. We sought to investigate predictors for various HF outcomes in HCM.
Methods
We studied 289 consecutive HCM patients with EF≥50%. Patients with outflow obstruction (peak pressure gradient ≥30mmHg) were defined as obstructive HCM. HF events assessed in this study were 1) HF admission and 2) progression to end-stage (EF<50%).
Results
The mean age was 63±16 years, 53% male, EF 61±5%, NYHA class 1.8±0.7, and 39% obstructive. During a median follow up of 5.2 [3.7–7.0] years, 48 HF admission and 19 progression to end-stage were observed. Only 8/48 (17%) patients with HF admission had progressed to end-stage; while 11/19 (58%) patients with progression to end-stage remained free from HF admission. Univariate Cox regression hazard analysis showed different prognostic predictors between HF admission and progression to end-stage (Table). Multivariate Cox regression hazard analysis showed atrial fibrillation was an independent predictor of HF admission (adjusted HR 2.711 [1.094–7.389], P=0.031); while LV end-systolic dimension was an independent predictor of progression to end-stage (adjusted HR 1.114 [1.018–1.229], P=0.025).

Conclusions
Different prognostic predictors were found for HF admission and progression to end-stage, suggesting the difficulty and multifactorial nature of HCM-related HF.

Abstract
Abstract
Background
Inflammation is a key driver of atherosclerosis and myocardial infarction (MI), and beyond proteins and microRNAs, long noncoding RNAs (lncRNAs) are implicated in inflammation control. To obtain further information on the role of lncRNAs in the context of atherosclerosis, we analyzed transcriptome maps of circulating immune cells (PBMCs) of post-MI patients in whom the lncRNA NEAT1 was suppressed. Here, we report immune disturbances in murine NEAT1 knockout models with wildtype or ApoE−/− genetic background.
Methods and results
RNA-sequencing (RNA-seq) of PBMCs from post-MI patients revealed profound transcriptome disturbances compared to healthy controls. Among these, NEAT1 suppression was notable since it affected the most highly expressed lncRNA as part of a molecular circuit also encompassing chemokines and interleukins.
We used NEAT1−/− mice to evaluate whether NEAT1 depletion per se may cause immune dysfunction. NEAT1−/− splenocytes displayed enhanced baseline ROS production, and RNA-seq identified anomalous expression and regulation of chemokines/ receptors, innate immunity genes, TNF and caspases. FACS revealed displayed anomalous Treg and TH cell differentiation in NEAT1−/− spleens vs. wildtype (WT).
Beyond grossly altered transcriptome, NEAT1−/− bone marrow derived macrophages (BMDMs) responded to LPS with increased (p<0.001) ROS production, enhanced baseline phagocytic activity (p<0.001), and attenuated proliferation (p=0.001). FACS revealed deregulated monocyte-macrophage differentiation in NEAT1−/− bone marrow and blood.
Further, NEAT1−/− mice displayed aortic wall CD68+ cell infiltration and there was evidence of myocardial inflammation which could lead to severe and potentially life-threatening structural damage in some of these animals. This observation suggests that even stochastic activation of the highly unstable NEAT1−/− immune system may trigger uncontrolled pathogenic cascades, explaining the survival disadvantage of NEAT1−/− mice.
In addition to these studies on homozygous NEAT1−/− deficiency in WT background, we obtained data on mice with partial i.e. heterozygous NEAT1−/+ deficiency on ApoE−/− background. Analysis of this new NEAT1−/+ ApoE−/− strain indicates that even partial NEAT1 deficiency leads to systemic inflammation with high IFN-gamma levels, when the animals are exposed to immune stress e.g. high LDL cholesterol.
Conclusions
Regarding the monocyte-enriched NEAT1 suppressed in post-MI PBMCs, the data from NEAT1−/− and NEAT1−/+ ApoE−/− mice document NEAT1 as a key immune system coordinator whose deficiency affects monocyte-macrophage and T cell differentiation and functions and renders the immune system unstable and highly vulnerable to immune stress. Since in patients NEAT1 is part of a molecular circuit persistently deregulated post-MI, too, it appears reasonable to further search for new therapeutic targets within this circuit, taking advantage of the described genetic animal models.

Abstract
Tumors of the skull base, such as meningiomas, tend to recur. With progress in free vascularized flap surgery, an increasing number of studies are investigating skull base reconstruction with free flaps after tumor removal. In this report, we discuss the results of second free flap surgery after skull base reconstructive surgery. We retrospectively analyzed data from patients treated at our center during the period from 2013 through 2017. All four patients identified had skull base anaplastic meningioma and had undergone radiotherapy. In all cases, the flap and donor blood vessel were sourced from sites that differed from those used in the previous surgeries. No complications developed, such as cerebrospinal fluid leakage, meningitis, wound infection, wound hemorrhage, or flap necrosis. Because the first flap was found to be unviable, it was difficult to preserve and was removed. Essential points in preventing complications are anchoring at the appropriate site, pinprick testing of the created flap, and use of multilayered countermeasures to prevent cerebrospinal fluid leakage.

Abstract
A prototypical electron-doped iron-based superconductor $LaFeAsO_{1-x}H_x$ undergoes an antiferromagnetic (AF) phase for $x \geq 0.49$. We performed NMR measurements on $LaFeAsO_{0.4}H_{0.6}$ at 3.7 GPa to investigate the magnetic properties in the vicinity of a pressure-induced QCP. The linewidth of $~^1H$-NMR spectra broadens at low temperatures below 30 K, suggesting that the ordered spin moments remain at 3.7 GPa. The coexistence of gapped and gapless spin excitations was confirmed in the ordered state from the relaxation time $T_1$ of $~^{75}As$. The pressure-induced QCP is estimated to be 4.1 GPa from the pressure dependence of the gapped excitation.

Abstract
Background Stratified mucin-producing intraepithelial lesion (SMILE) is a rare precursor lesion in the uterine cervix that is considered a variant of adenocarcinoma in situ (AIS). Although human papillomavirus (HPV) is thought to be related to the development of SMILE, there is little information available on the detection of HPV integrated into the lesion. Case presentation A 30-year-old female underwent a routine uterine cervical cancer screening, and her Pap smear indicated the possible existence of atypical glandular cells. A cervical biopsy with endocervical curettage was performed. The histopathological analysis showed that she had SMILE and high-grade squamous intraepithelial lesion (HSIL) on her cervix. The lesion was found to be positive for HPV genotypes 52 and 68 by multiplex PCR. In situ hybridization with HPV RNA probes revealed that these HPV types were involved in the onset of HSIL and SMILE, respectively. Conclusions Rare, high-risk HPV genotypes may contribute to the development of SMILE, and their detection can be useful for preventing the progression to carcinoma and ensuring adequate patient management.

Abstract
BACKGROUND Fatal adverse effects or relapse can occur with excessive or insufficient busulfan exposure in hematopoietic stem cell transplantation. Given that busulfan is mainly metabolized by glutathione S-transferase (GST), we investigated the influence of GST polymorphisms on busulfan pharmacokinetics in Japanese pediatric patients. METHODS Blood samples were taken from patients receiving high-dose i.v. busulfan as the first dose. Plasma busulfan concentration was measured using high-performance liquid chromatography. The area under the plasma busulfan concentration-time curve (AUC) was calculated. The genotype of GSTA1 was determined on polymerase chain reaction (PCR)-restriction fragment length polymorphism. Multiplex PCR was used to detect the presence or absence of GSTM1 and GSTT1 in the genomic DNA samples. RESULTS Twenty patients were consecutively enrolled. Phenotype prediction was defined as follows: poor metabolizer (n = 4), one or more GSTA1*B haplotype or GSTM1/GSTT1 double-null genotypes; and extensive metabolizer (n = 16), other genotypes. GSTA1, M1, and T1 independently had no significant differences in AUC0-∞ , clearance or elimination rate constant. For the infant with unexpectedly high AUC0-∞ (2,591 μmol/L min), the GSTA1, M1, and T1 polymorphisms were wild type. On further analysis, the poor metabolizer group had lower clearance and higher AUC0-∞, except for the aforementioned patient, compared with the extensive metabolizer group (1,531 vs 1,010 μmol/L min; P < 0.01). CONCLUSIONS GST polymorphisms may have affected busulfan pharmacokinetics, but these effects were obscured by other factors, such as underlying disease, systemic conditions, treatment history, and race.

Abstract
AIM Preoperative anaemia is associated with adverse outcomes in colorectal cancer (CRC). To clarify the reason for this we aimed to comprehensively assess the association of preoperative anaemia with tumour characteristics, host systemic inflammation and nutrition status, and perioperative blood transfusion. METHOD We used an integrated database of 592 CRC patients. The association of preoperative anaemic subtype, calculated from haemoglobin and erythrocyte mean corpuscular volume levels, with patient outcome, preoperative serum data relating to systemic inflammation and nutrition and perioperative blood transfusion was analysed. RESULTS Preoperative anaemia was significantly associated with poorer overall survival and relapse-free survival (RFS); in particular microcytic anaemia had a trend to poorer RFS than other forms of anaemia (P = 0.0648). In addition, preoperative anaemia was significantly correlated with right-sided tumours, greater depth of tumour invasion, use of neoadjuvant chemotherapy, poorer prognostic nutritional index and higher modified Glasgow Prognostic Score (mGPS). Microcytic anaemia in particular had a strong association with a greater depth of tumour invasion (P = 0.0072) and higher mGPS (P = 0.0058) than other causes of anaemia. Perioperative blood transfusion for CRC patients with anaemia was associated with adverse outcomes. CONCLUSIONS Preoperative anaemia, especially microcytic anaemia, was associated with poor patient outcomes, possibly due to poor systemic inflammatory and nutritional status, and it was not improved by perioperative blood transfusion. Our data suggest that preoperative anaemia and the anaemic subtype may serve as an easily available predictor of outcome in CRC.

Abstract
Behavioural and cognitive processes play important roles in mediating an individual's interactions with its environment. Yet, while there is a vast literature on repeatable individual differences in behaviour, relatively little is known about the repeatability of cognitive performance. To further our understanding of the evolution of cognition, we gathered 44 studies on individual performance of 25 species across six animal classes and used meta-analysis to assess whether cognitive performance is repeatable. We compared repeatability (R) in performance (1) on the same task presented at different times (temporal repeatability), and (2) on different tasks that measured the same putative cognitive ability (contextual repeatability). We also addressed whether R estimates were influenced by seven extrinsic factors (moderators): type of cognitive performance measurement, type of cognitive task, delay between tests, origin of the subjects, experimental context, taxonomic class and publication status. We found support for both temporal and contextual repeatability of cognitive performance, with mean R estimates ranging between 0.15 and 0.28. Repeatability estimates were mostly influenced by the type of cognitive performance measures and publication status. Our findings highlight the widespread occurrence of consistent inter-individual variation in cognition across a range of taxa which, like behaviour, may be associated with fitness outcomes.This article is part of the theme issue 'Causes and consequences of individual differences in cognitive abilities'.

Abstract
Fewer women than men pursue careers in science, technology, engineering and mathematics (STEM), despite girls outperforming boys at school in the relevant subjects. According to the 'variability hypothesis', this over-representation of males is driven by gender differences in variance; greater male variability leads to greater numbers of men who exceed the performance threshold. Here, we use recent meta-analytic advances to compare gender differences in academic grades from over 1.6 million students. In line with previous studies we find strong evidence for lower variation among girls than boys, and of higher average grades for girls. However, the gender differences in both mean and variance of grades are smaller in STEM than non-STEM subjects, suggesting that greater variability is insufficient to explain male over-representation in STEM. Simulations of these differences suggest the top 10% of a class contains equal numbers of girls and boys in STEM, but more girls in non-STEM subjects.
