Abstract
Plants are exposed to a variety of environmental stress, and starvation of inorganic phosphorus can be a major constraint in crop production. In plants, in response to phosphate deficiency in soil, miR399, a type of microRNA (miRNA), is up-regulated. By detecting miR399, the early diagnosis of phosphorus deficiency stress in plants can be accomplished. However, general miRNA detection methods require complicated experimental manipulations. Therefore, simple and rapid miRNA detection methods are required for early plant nutritional diagnosis. For the simple detection of miR399, microfluidic technology is suitable for point-of-care applications because of its ability to detect target molecules in small amounts in a short time and with simple manipulation. In this study, we developed a microfluidic device to detect miRNAs from filtered plant extracts for the easy diagnosis of plant growth conditions. To fabricate the microfluidic device, verification of the amine-terminated glass as the basis of the device and the DNA probe immobilization method on the glass was conducted. In this device, the target miRNAs were detected by fluorescence of sandwich hybridization in a microfluidic channel. For plant stress diagnostics using a microfluidic device, we developed a protocol for miRNA detection by validating the sample preparation buffer, filtering, and signal amplification. Using this system, endogenous sly-miR399 in tomatoes, which is expressed in response to phosphorus deficiency, was detected before the appearance of stress symptoms. This early diagnosis system of plant growth conditions has a potential to improve food production and sustainability through cultivation management.

Abstract
It has recently been reported that cholangiocyte organoids can be established from primary human hepatocytes. The purpose of this study was to culture the organoids in monolayers on inserts to investigate the biliary excretory capacity of drugs. Cholangiocyte organoids prepared from hepatocytes had significantly higher mRNA expression of CK19, a bile duct epithelial marker, compared to hepatocytes. The organoids also expressed mRNA for efflux transporters involved in biliary excretion of drugs, P-glycoprotein (P-gp), multidrug resistance-associated protein 2 (MRP2), and breast cancer resistance protein (BCRP). The subcellular localization of each protein was observed. These results suggest that the membrane-cultured cholangiocyte organoids are oriented with the upper side being the apical membrane side (A side, bile duct lumen side) and the lower side being the basolateral membrane side (B side, hepatocyte side), and that each efflux transporter is localized to the apical membrane side. Transport studies showed that the permeation rate from the B side to the A side was faster than from the A side to the B side for the substrates of each efflux transporter, but this directionality disappeared in the presence of inhibitor of each transporter. In conclusion, the cholangiocyte organoid monolayer system has the potential to quantitatively evaluate the biliary excretion of drugs. The results of the present study represent an unprecedented system using human cholangiocyte organoids, which may be useful as a screening model to directly quantify the contribution of biliary excretion to the clearance of drugs.

Abstract
INTRODUCTION Trabecular bone score (TBS) is partially independent of fracture risk. Reference values for TBS have not been established in official guidelines, and thus clinicians often have difficulty interpreting TBS results. This study aimed to investigate whether reference values for TBS could be a valid indicator for clinical vertebral fracture (CVF). MATERIALS AND METHODS This cross-sectional study involved 231 women with CVF and 563 women without CVF aged 60-90 years who underwent dual-energy X-ray absorptiometry during 2019-2023. They were divided into osteoporosis, osteopenia, and normal groups according to bone mineral density of the lumbar spine. Reference values for TBS were defined as low (≤ 1.23), intermediate (1.23-1.31), and high (≥ 1.31). RESULTS Among patients without anti-osteoporosis treatment (n = 476), the proportion with low TBS was 36.7% in the CVF group and 10.7% in the control group. The proportion with CVF was higher in the low TBS group than in the intermediate and high TBS groups, especially in the osteoporosis group (p < 0.001). The odds ratio for CVF was higher in the low TBS group than in the intermediate and high especially in patients with normal BMD and osteoporosis. The TBS cut-off values for incidence of CVF in the osteoporosis, osteopenia, and normal groups were 1.224, 1.319, and 1.322, respectively. CONCLUSIONS The reference value for low TBS (≤ 1.23) was useful as an indicator for CVF, especially in patients with osteoporosis. It is expected that reference values for TBS will be established in official guidelines in the future.

Abstract
Two endornaviruses, Phytophthora endornavirus 2 (PEV2) and Phytophthora endornavirus 3 (PEV3), have been discovered in pathogens targeting asparagus. In this study, we analyzed the nick structure in the RNA genomes of PEV2 and PEV3 in the host oomycetes. Northern blot hybridization using positive and negative strand-specific RNA probes targeting the 5' and 3' regions of PEV2 and PEV3 RNA genomes revealed approximately 1.0 kilobase (kb) RNA fragments located in the 5' regions of the two genomes. 3' RACE analysis determined that the size of the RNA fragments were 958 nucleotides (nt) for PEV2 and 968 nt for PEV3. We have successfully constructed full-length cDNA clones of the entire RNA genomes of PEV2 and PEV3 using a homologous recombination system in the yeast, Saccharomyces cerevisiae. These full-length cDNA sequences were ligated downstream of a constitutive expression promoter (TDH3) or a galactose-inducing promoter (GAL1) in the shuttle vector to enable the production of the full-length RNA transcripts of PEV2 and PEV3 in yeast cells. Interestingly, a 1.0 kb RNA fragment from the PEV3 positive-strand transcript was also detected with a 5'-region RNA probe, indicating that site-specific cleavage also occurred in yeast cells. Further, when PEV2 or PEV3 mRNA was overexpressed under the GAL1 promoter, yeast cell growth was suppressed. A fusion protein combining EGFP to the N-terminus of the full-length PEV2 ORF or C-terminus of the full-length PEV3 ORF was expressed, and allowed PEV2 and PEV3 ORFs to be successfully visualized in yeast cells. Expression of the fusion protein also revealed presence of heterogeneous bodies in the cells.

Abstract
The T2K experiment presents new measurements of neutrino oscillation parameters using 19.7 ( 16.3 ) × 10 20 protons on target (POT) in (anti-)neutrino mode at the far detector (FD). Compared to the previous analysis, an additional 4.7 × 10 20 POT neutrino data was collected at the FD. Significant improvements were made to the analysis methodology, with the near-detector analysis introducing new selections and using more than double the data. Additionally, this is the first T2K oscillation analysis to use NA61/SHINE data on a replica of the T2K target to tune the neutrino flux model, and the neutrino interaction model was improved to include new nuclear effects and calculations. Frequentist and Bayesian analyses are presented, including results on sin 2 θ 13 and the impact of priors on the δ CP measurement. Both analyses prefer the normal mass ordering and upper octant of sin 2 θ 23 with a nearly maximally CP-violating phase. Assuming the normal ordering and using the constraint on sin 2 θ 13 from reactors, sin 2 θ 23 = 0 . 561 - 0.032 + 0.021 using Feldman-Cousins corrected intervals, and Δ m 32 2 = 2 . 494 - 0.058 + 0.041 × 10 - 3 eV 2 using constant Δ χ 2 intervals. The CP-violating phase is constrained to δ CP = - 1 . 97 - 0.70 + 0.97 using Feldman-Cousins corrected intervals, and δ CP = 0 , π is excluded at more than 90% confidence level. A Jarlskog invariant of zero is excluded at more than 2 σ credible level using a flat prior in δ CP , and just below 2 σ using a flat prior in sin δ CP . When the external constraint on sin 2 θ 13 is removed, sin 2 θ 13 = 28 . 0 - 6.5 + 2.8 × 10 - 3 , in agreement with measurements from reactor experiments. These results are consistent with previous T2K analyses.

Abstract
Klebsiella pneumoniae has the ability to form biofilm; therefore, the treatment of prosthetic joint infection involving K. pneumoniae is often challenging. This report describes the first case of acute hematogenous prosthetic knee joint infection with K. pneumoniae that occurred as a result of an asymptomatic gallbladder abscess. The patient was a 78-year-old man who underwent bilateral total knee arthroplasty 6 years ago. He had pain and swelling in his right knee. The synovial fluid culture of the right knee revealed K. pneumoniae and prosthetic joint infection was diagnosed. Computed tomography revealed a gallbladder abscess in the absence of right upper abdominal pain. The patient underwent simultaneous debridement of the knee and open cholecystectomy. The treatment was successful and the prosthesis was retained. In cases of hematogenous prosthetic joint infection with K. pneumoniae, other sources of infection should be suspected and investigated regardless of whether they are symptomatic.

Abstract
The ability to engineer biologically viable hepatocytes and tissue matrices with long-term functional maintenance has attracted considerable interest in the fields of hepatocyte transplantation and liver tissue engineering. Here, newly developed hepatocyte sheets supplemented with adipose-derived stem cells (ADSCs) were evaluated to assess the effects of ADSCs on hepatocyte function and engraftment into the subcutaneous space. Eight-week-old male C57BL/6J mice were used as donors and 6-week-old male C.B-17/Icr-scid/scid mice were used as recipients. Hepatocyte-ADSC composite sheets were developed using temperature-responsive culture dishes. Hepatocyte viability in the hepatocyte-ADSC composite sheets was evaluated in an in vitro assay, and the outcome of subcutaneous transplantation of the sheet was evaluated. Hepatocyte viability was sustained in the hepatocyte-ADSC composite sheets in vitro. Albumin secretion was significantly higher (p = 0.015) in the hepatocytes of the hepatocyte-ADSC composite sheets (70.5 μg/mL) than in hepatocyte-only sheets (24.0 μg/mL). Cytokine assays showed that hepatocyte growth factor and interleukin-6 were contributed by ADSCs and not hepatocytes, which were not capable of constitutively secreting them. Immunohistochemically, phosphorylated STAT3 and c-MET expression in hepatocytes in the hepatocyte-ADSC composite sheets was significantly higher than that in the hepatocyte-only sheets. Engraftment of the transplanted hepatocyte-ADSC composite sheets was significantly enhanced without pretreatment of the subcutaneous tissue to induce a vascular network. In the hepatocyte-ADSC composite sheets, the viability of the hepatocytes was significantly maintained as the co-cultured ADSCs provided cytokines, enhancing pivotal cell signaling necessary for hepatocyte activity.

Abstract
The family Hadakaviridae, including the genus Hadakavirus, accommodates capsidless viruses with a 10- or 11-segmented positive-sense (+) RNA genome. Currently known hosts are ascomycetous filamentous fungi. Although phylogenetically related to polymycovirids with a segmented double-stranded RNA genome and certain encapsidated picorna-like viruses, hadakavirids are distinct in their lack of a capsid ('hadaka' means naked in Japanese) and their consequent inability to be pelleted by conventional ultracentrifugation; they show ribonuclease susceptibility in host tissue homogenates. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Hadakaviridae, which is available at ictv.global/report/hadakaviridae.

Abstract
Cellular senescence caused by oncogenic stimuli is associated with the development of various age-related pathologies through the senescence-associated secretory phenotype (SASP). SASP is mediated by the activation of cytoplasmic nucleic acid sensors. However, the molecular mechanism underlying the accumulation of nucleotide ligands in senescent cells is unclear. In this study, we revealed that the expression of RNaseH2A, which removes ribonucleoside monophosphates (rNMPs) from the genome, is regulated by E2F transcription factors, and it decreases during cellular senescence. Residual rNMPs cause genomic DNA fragmentation and aberrant activation of cytoplasmic nucleic acid sensors, thereby provoking subsequent SASP factor gene expression in senescent cells. In addition, RNaseH2A expression was significantly decreased in aged mouse tissues and cells from individuals with Werner syndrome. Furthermore, RNaseH2A degradation using the auxin-inducible degron system induced the accumulation of nucleotide ligands and induction of certain tumourigenic SASP-like factors, promoting the metastatic properties of colorectal cancer cells. Our results indicate that RNaseH2A downregulation provokes SASP through nucleotide ligand accumulation, which likely contributes to the pathological features of senescent, progeroid, and cancer cells.

Abstract
Background: Baseball is one of the most popular sports in Asia. It is known that baseball
can easily lead to back pain. However, there has been no survey of low back
pain (LBP) and lumbar disc degeneration in Japanese professional baseball
players to date. Purpose: To investigate the cause of LBP and lumbar degeneration in professional
Japanese baseball players. Study Design: Cross-sectional study; Level of evidence, 3. Methods: We retrospectively reviewed the medical records of Japanese professional
baseball players with LBP who visited our hospital. Data were collected from
July 2018 to April 2021. We also investigated whether the results differed
between players in their 20s and 30s or between pitchers and fielders. Data
analysis was performed using the chi-square test. Results: We surveyed 32 professional baseball players. The most frequent causes of LBP
among players in their 20s (n = 21) were lumbar disc herniation (LDH; 57%)
and spondylolysis (24%). Of the players with spondylolysis, 50% had
adult-onset spondylolysis. Players in their 30s (n = 11) most commonly had
discogenic pain (55%) as well as LDH and facet joint arthritis (each 18%).
The incidence of lumbar intervertebral disc degeneration was significantly
higher in players in their 30s (91%) than those in their 20s (14%), as was
the incidence of Schmorl nodes and Modic type 1 changes. There was no
significant difference in the cause of LBP or the incidence of lumbar
intervertebral disc degeneration between pitchers and fielders
(P = .59). Conclusion: Among professional baseball players in their 20s, lumbar degeneration was
less common, and they most frequently developed diseases less related to
degeneration, such as LDH. However, among players in their 30s, lumbar
degeneration was more advanced, and degenerative diseases such as discogenic
pain occurred more frequently. Research on training methods could lead to
the prevention of LBP. Our data may be applicable to other professional
athletes and will contribute to diagnosis and treatment.

Abstract
Backgroud Dual SC screw (DSCS) is a unique concept internal fixation device consisting of a sliding screw and barrel assembly that enables compression force to be applied to the femoral neck fracture side. There are two types of barrels: a thread barrel and a plate barrel that has a one-holed side plate to prevent varus deformity. We report clinical results of the application of a DSCS with combined use of a thread barrel screw as an anti-rotational screw and a plate barrel screw as a compression hip screw. Methods We used DSCS for femoral neck fractures in 196 hip joints of 190 patients between November 2005 and June 2017. Among them, 70 hips in 66 patients (13 men and 53 women; mean age, 73.2 years) were followed up for at least 24 months. There were 53 nondisplaced fractures (Garden's classification stage 1 or 2) and 17 displaced fractures (stage 3 or 4). We evaluated the postoperative walking ability of the patients who were followed up for at least 24 months and examined details of all complications. Results The mean follow-up period was 37.4 months (range, 24–144 months). Forty-two (64%) out of the 66 patients who were followed up for at least 2 years were able to walk independently with or without a cane. The incidence of complications was 11.5% in nondisplaced fractures and 17.5% in displaced fractures, and arthroplasty was required in 5.8% and 5.0%, respectively. The most frequent complication was secondary displacement including cutout and shortening of the femoral neck, but no implants showed varus displacement. Conclusions The application of DSCS for the treatment of femoral neck fractures had satisfactory results. The complication rate was low, and there was no postoperative varus displacement of DSCS in either displaced or nondisplaced fractures. We suggest DSCS is a reliable option for both displaced and nondisplaced femoral neck fractures.

Abstract
Alternaria alternata virus 1 (AaV1) has been identified in the saprophytic fungus Alternaria alternata strain EGS 35-193. AaV1 has four genomic double-stranded (ds)RNA segments (dsRNA1-4) packaged in isometric particles. The 3' end of each coding strand is polyadenylated (36-50nt), but the presence of a cap structure at each 5' end has not previously been investigated. Here, we have characterized the AaV1 genome and found that it has unique features among the mycoviruses. We confirmed the existence of cap structures on the 5' ends of the AaV1 genomic dsRNAs using RNA dot blots with anti-cap antibodies and the oligo-capping method. Polyclonal antibodies against purified AaV1 particles specifically bound to an 82kDa protein, suggesting that this protein is the major capsid component. Subsequent Edman degradation indicated that the AaV1 dsRNA3 segment encodes the major coat protein. Two kinds of defective AaV1 dsRNA2, which is 2,794bp (844 aa) in length when intact, appeared in EGS 35-193 during subculturing, as confirmed by RT-PCR and northern hybridization. Sequence analysis revealed that one of the two defective dsRNA2s contained a 231bp deletion, while the other carried both the 231bp deletion and an additional 465bp deletion in the open reading frame. Both deletions occurred in-frame, resulting in predicted proteins of 767 aa and 612 aa. The fungal isolates carrying virions with the defective dsRNA2s showed impaired growth and abnormal pigmentation. To our best knowledge, AaV1 is the first dsRNA virus to be identified with both 5' cap and 3'poly(A) structures on its genomic segments, as well as the specific deletions of dsRNA2.

Abstract
BACKGROUND This retrospective study aimed to compare the discriminative performance between magnetic resonance elastography (MRE) and biological markers in detecting liver fibrosis and in predicting postoperative ascites (PA). METHODS We enrolled 77 patients consecutively who underwent hepatectomy between March 2017 and June 2019. Liver fibrosis was histopathologically graded using the METAVIR scoring system as reference. Discriminative performance of non-invasive assessments in detecting different stages of liver fibrosis and predicting PA was evaluated by receiver-operator curve analysis. RESULTS The concordance indices (C-indices) for MRE and biological markers for detecting significant fibrosis (≥F2) and cirrhosis (F4) were: MRE, 0.84 and 0.86; Wisteria floribunda agglutinin + Mac-2 binding protein (WM2BP), 0.63 and 0.71; Hyaluronic acid (HA), 0.72 and 0.75; 7 S-type 4 collagen (T4C), 0.61 and 0.66; APRI, 0.76 and 0.83; and Fib-4, 0.75 and 0.76. Univariable logistic analysis for predicting PA showed that C-indices were 0.751 (p = 0.007), 0.798 (p = 0.106), 0.771 (p = 0.050), 0.674 (p = 0.855), 0.655 (p = 0.263), and 0.560 (p = 0.640) for MRE, WM2BP, Fib-4, HA, APRI, and T4C, respectively. CONCLUSION MRE has a higher diagnostic performance than biological markers in detecting the stages of liver fibrosis and is a predictor for PA after hepatectomy.

Abstract
BACKGROUND Prediction of post-hepatectomy liver failure (PHLF) based on remnant liver function reserve is important for successful hepatectomy. The aim of this study was to investigate whether intraoperative indocyanine green (ICG) clearance in a future remnant liver was a predictor of PHLF. METHODS This prospective study enrolled 31 consecutive patients who underwent anatomical hepatectomy between June 2016 and August 2019. Intraoperative ICG plasma disappearance rate (ICG-PDR) and ICG retention rate at 15 min (ICG-R15) were measured after clamping the selective hepatic inflow to the liver to be resected. The discriminative performance of the ICG-associated variables for the prediction of PHLF grade B/C was evaluated by receiver operator curve (ROC) analysis. RESULTS Of the operations performed, 87.1% were major hepatectomy. PHLF Grade B/C was observed in eight patients (25.8%) with no mortality. The concordance indices of intraoperative ICG-PDR and ICG-PDR for predicting PHLF were 0.834 (95% CI, 0.69-0.98) and 0.834 (95% CI, 0.69-0.98), respectively. A subgroup analysis of patients with preoperative biliary drainage (BD) (n = 17) showed that the concordance indices of intraoperative ICG-PDR increased to 0.923 (95% CI, 0.79-1.00). CONCLUSIONS Intraoperative ICG clearance in the remnant liver was a promising predictor for PHLF in patients undergoing anatomical hepatectomy, especially in patients with BD.

Abstract
In Oxford unicompartmental knee arthroplasty, the relationship between the mobile bearing and the vertical wall of the tibial tray is important in preventing bearing dislocation. Separation of the bearing from the vertical wall can cause spinning of the bearing with an increased risk of subsequent dislocation. We report on intraoperative adjustment of the tibial tray performed to prevent the bearing from spinning. After tibial and femoral bone cutting and adjustment of the flexion and extension gap, the trial bearing is inserted and the bearing-vertical wall distance is evaluated before the preparation using the tibial template and bearing trial. In the case of separation, it can be resolved by medialization with or without rotational adjustment. The technique is useful and can be easily performed, it is therefore recommendable for all cases of Oxford mobile-bearing unicompartmental arthroplasty.

Abstract
Two novel endornaviruses, Phytophthora endornavirus 2 (PEV2) and Phytophthora endornavirus 3 (PEV3) were found in isolates of a Phytophthora pathogen of asparagus collected in Japan. A molecular phylogenetic analysis indicated that PEV2 and PEV3 belong to the genus Alphaendornavirus. The PEV2 and PEV3 genomes consist of 14,345 and 13,810 bp, and they contain single open reading frames of 4,640 and 4,603 codons, respectively. Their polyproteins contain the conserved domains of an RNA helicase, a UDP-glycosyltransferase, and an RNA-dependent RNA polymerase, which are conserved in other alphaendornaviruses. PEV2 is closely related to Brown algae endornavirus 2, whereas PEV3 is closely related to Phytophthora endornavirus 1 (PEV1), which infects a Phytophthora sp. specific to Douglas fir. PEV2 and PEV3 were detected at high titers in two original Phytophthora sp. isolates, and we found a sub-isolate with low titers of the viruses during subculture. We used the high- and low-titer isolates to evaluate the effects of the viruses on the growth, development, and fungicide sensitivities of the Phytophthora sp. host. The high-titer isolates produced smaller mycelial colonies and much higher numbers of zoosporangia than the low-titer isolate. These results suggest that PEV2 and PEV3 inhibited hyphal growth and stimulated zoosporangium formation. The high-titer isolates were more sensitive than the low-titer isolate to the fungicides benthiavalicarb-isopropyl, famoxadone, and chlorothalonil. In contrast, the high-titer isolates displayed lower sensitivity to the fungicide metalaxyl (an inhibitor of RNA polymerase I) when compared with the low-titer isolate. These results indicate that persistent infection with PEV2 and PEV3 may potentially affect the fungicide sensitivities of the host oomycete.

Abstract
A 45-year-old woman with abdominal pain after minor trauma was referred to our hospital. Computed tomography (CT) showed a hypovascular tumor in the left liver lobe. A tumor biopsy revealed granuloma, although no findings indicated malignancy or infection. A follow-up imaging study showed spread of the hepatic tumor. Her abdominal pain worsened after a second minor trauma. CT revealed an intratumor abscess, and pus overflowed from the patient's umbilicus. The abscess was improved by antibiotics and drainage therapy. In this case, unusual imaging findings and an atypical disease course of a hepatic inflammatory pseudotumor were observed.

Abstract
Early intra-abdominal infection (IAI) following pancreaticoduodenectomy (PD) is an initial event relating to morbidities caused by postoperative pancreatic fistula (POPF). The aims of this study were to determine factors associated with IAI, and to investigate its impact on postoperative outcome. Consecutive patients, 113 in total, who underwent PD at Fukushima Medical University Hospital between January 2012 and September 2017 were included in this retrospective study. IAI was defined by positive bacterial culture from intra-abdominal drainage fluid any time through postoperative day 3 (POD3). Logistic regression analysis was used to identify the relevant factors associated with IAI. The clinical impact of the POD3 infection indicators related to POPF were assessed by multivariate analysis. The incidence of IAI, POPF, and mortality were 36.1%, 36.1%, and 0%, respectively. Independent factors associated with IAI were preoperative biliary drainage (PBD) (OR = 2.91, CI = 1.16-7.33, p = 0.023) and soft pancreas (OR = 8.67, CI = 2.37-31.77, p = 0.001). Among infection markers on POD3, the significant factors for POPF were CRP (OR = 1.18, CI = 1.08-1.30, p < 0.001), IAI (OR = 7,37, CI = 2.53-21.5, p < 0.001), and drain amylase (OR = 1.00, CI = 1.00-1.01, p = 0.001). In conclusion, PBD, soft pancreas, and higher age were associated with IAI. IAI has a significantly negative impact on postoperative outcome.

Abstract
Dendritic cell inhibitory receptor 3 (DCIR3, Clec4a3) and dendritic cell inhibitory receptor 4 (DCIR4, Clec4a1) are C-type lectin receptors that belong to mouse dendritic cell immunoreceptor (DCIR) family. We recently showed that DCIR3 and DCIR4 are co-expressed on inflammatory and patrolling monocytes. In this study, we investigated the expression of DCIR3 and DCIR4 on tissue-resident macrophages. We found that spleen red pulp macrophages, liver Kupffer cells, large and small peritoneal macrophages and small intestinal macrophages expressed both DCIR3 and DCIR4. By contrast, lung alveolar macrophages expressed DCIR3 but not DCIR4 and brain microglia expressed neither DCIR3 nor DCIR4. Considerable part of tissue-resident macrophages are derived from embryonic precursors. We, therefore, examined the expression of DCIR3 and DCIR4 on the embryonic precursors. Yolk-sac macrophages from embryonic day (E) 8.5 embryos expressed both DCIR3 and DCIR4, while DCIR3 and DCIR4 were expressed on subpopulations of fetal liver monocytes from E14.5 embryos. Our results, together with previous data, indicate that the expression of DCIR3 and DCIR4 is widely shared by mononuclear phagocytes, including monocytes and macrophages, and that the expression of DCIR3 and DCIR4 on the embryonic precursors are not always retained by their progenies, suggesting that expression of DCIR3 and DCIR4 on tissue-resident macrophages might be regulated by environment of the tissues where the embryonic precursors differentiate into macrophages. The majority of tissue-resident macrophages express DCIR3 and DCIR4. Brain microglia lack the expression of DCIR3 and DCIR4. Lung alveolar macrophages express DCIR3 but not DCIR4. Macrophages do not always retain DCIR3/DCIR4 expression on their precursors.

Abstract
To reduce the stress on the medial tibial cortex and to decrease the risk of fracture, a varus cut of the tibia appears to be a reasonable alternative to the orthogonal cut by conventional methods. We present a new instrument and procedure, which enables a varus tibial cut for Oxford unicompartmental knee arthroplasty. We used a custom-made, slidable fixator instead of the standard fixator to set the extramedullary rod on the leg. We also made a numeric formula and a chart to arrange the varus cutting angle using the length of the mediolateral shift of the distal end and the longitudinal extension length of the extramedullary tibial rod. A varus cut up to 4.5° can be controlled. This technique is a simple and useful means of obtaining a varus tibial cut for Oxford unicompartmental knee arthroplasty.

Abstract
New succinate dehydrogenase inhibitor fungicides (SDHIs), isopyrazam, pyraziflumid and isofetamid were introduced in the Japanese market in 2017-2018 to control powdery mildew on cucumber. SDHI resistance of the disease fungus (Podosphaera xanthii) was first reported during 2008-2009 against boscalid. Then, penthiopyrad which belongs to SDHIs was introduced in 2010, but subsequent monitoring study was not performed. We investigated the sensitivity of P. xanthii field isolates from Ibaraki Prefecture, Japan, to SDHIs and SdhB, SdhC and SdhD gene mutations, using a leaf disc assay and SDH gene analysis. A total of 19 out of the 22 selected isolates showed resistance to SDHIs. The 19 isolates were phenotypically categorized into three types: Resistant I as moderately and Resistant II as highly resistant to penthiopyrad, isopyrazam and pyraziflumid but sensitive to isofetamid and Resistant III as highly resistant to isofetamid but sensitive to the other three SDHIs. SDH gene analysis revealed that Resistant I and III isolates carried a substitution in PxD-S121P and PxC-A86V, respectively. Resistant II carried three different substitutions: PxC-G151R, PxC-G172D, and PxD-H137R. Among 127 isolates sampled from 16 cucumber greenhouses, 54 exhibited Resistant I phenotype and carried only PxD-S121P. Fifty-six isolates exhibited Resistant II and carried PxC-G151R (four isolates), PxC-G172D (24), and PxD-H137R (28). Only two isolates expressed the Resistant III phenotype carrying PxC-A86V. To the best of our knowledge, this is the first report demonstrating cross-resistance patterns and the molecular characterization of SDHIs in P. xanthii.

Abstract
BACKGROUND Bemisia tabaci is a notorious agricultural pest that causes serious damage to many crops via herbivory and spread of viral diseases. Effective control measures are, therefore, required. Integrating entomopathogenic fungi into the chemical control system offers promise for B. tabaci management. RESULTS In-vitro assays on the augmentative effect of Beauveria bassiana GHA strain with insecticides, and its compatibility with fungicides were tested. Varying egg mortality was observed for most insecticides except for milbemectin. Pyrifluquinazon was less effective against the nymphs. Flonicamid showed no insecticidal effect on either nymphs or adults. However, increased mortality in nymphs and adults was observed when flonicamid was mixed with Beauveria bassiana GHA strain. Furthermore, no significant synergistic effect of mixing pesticides with B. bassiana GHA strain was observed. Most insecticides (when not mixed with B. bassiana) showed high (>80%) mortality against B. tabaci nymphs and adults. Most fungicides tested showed no inhibitory effects on B. bassiana GHA strain against B. tabaci nymphs and adults. Fungistatic effect was observed in the mycelial and spore germination inhibition studies. Weekly rotation of some pesticides with B. bassiana GHA strain in greenhouse conditions yielded significant reduction in different growth stages of B. tabaci. However, no significant difference in viral incidence was observed. CONCLUSION Laboratory and field tests showed positive effects of augmenting pesticides and B. bassiana GHA strain against B. tabaci nymphs and adults. Therefore, augmentation of pesticides and B. bassiana GHA strain is one prospect towards developing an effective B. tabaci IPM system. © 2020 Society of Chemical Industry.

Abstract
A putative endornavirus was detected in Carolina geranium (Geranium carolinianum) in Louisiana, USA. The virus was provisionally named Geranium carolinianum endornavirus 1 (GcEV1). The viral RNA was sequenced, and it consisted of 14,625 nt containing a single ORF coding a putative polyprotein of 4815 aa with conserved domains for a helicase 1, peptidase C97, glycosyl transferase GTB-type, and RNA-dependent RNA polymerase 2. The 5'end consisted of 130 nt while the 3'end consisted of 54 nt ending in nine cytosine residues. The closest relative to GcEV1 was Phaseolus vulgaris endornavirus 3. In phylogenetic analyses, GcEV1 clustered with members of the genus Alphaendornavirus. GcEV1 was detected in 57 of 60 G. carolinianum plants collected from three distinct agroecosystems. The virus was not detected in eight other species of the genus Geranium. There was no association of a particular phenotypic trait of the host with the presence or absence of the virus. GcEV1 was transmitted at a rate of 100% in seeds of a self-pollinated G. carolinianum plant.

Abstract
Plant grafting is conducted for fruit and vegetable propagation, whereby a piece of living tissue is attached to another through cell-cell adhesion. However, graft compatibility limits combinations to closely related species, and the mechanism is poorly understood. We found that Nicotiana is capable of graft adhesion with a diverse range of angiosperms. Comparative transcriptomic analyses on graft combinations indicated that a subclade of β-1,4-glucanases secreted into the extracellular region facilitates cell wall reconstruction near the graft interface. Grafting was promoted by overexpression of the β-1,4-glucanase. Using Nicotiana stem as an interscion, we produced tomato fruits on rootstocks from other plant families. These findings demonstrate that the process of cell-cell adhesion is a potential target to enhance plant grafting techniques.

Abstract
The present case involved a 60-year-old man with autoimmune pancreatitis (AIP). While his AIP was in remission for 6 years, a follow-up CE-CT revealed a dilated main pancreatic duct (MPD) and an enhanced mural nodule. Fluorodeoxyglucose uptake was positive on positron emission tomography. Endoscopic retrograde pancreatography showed a filling defect of the MPD, and pancreatoscopy revealed a nodule partially covered with papillary lesions. Although a repeat biopsy revealed no evidence of malignancy, we speculated that there was a high likelihood of main-duct-type intraductal papillary mucinous neoplasm (IPMN)-derived carcinoma concomitant with AIP. Subsequently, the patient underwent subtotal stomach-preserving pancreaticoduodenectomy. A surgical specimen showed a 35 mm protuberant papillary lesion with abundant stroma, located in the main duct of the pancreas. Further histological evaluation revealed that the nodule was predominantly composed of IPMN with low-grade dysplasia, which was accompanied by abundant IgG4-positive lymphoplasmacytic infiltration, and fibrosis existed predominantly around the IPMN. The epithelium of the cyst showed mucinous hyperplasia with focal papillary structures of gastric phenotype (MUC5A+, MUC6+, MUC1-, MUC2-, CDX-). After surgical resection, we did not find any imaging evidence suggesting a recurrent tumor and AIP relapse in the remnant pancreas. In conclusion, we report a case of IPMN coincidentally found in a patient with type 1 AIP. Active AIP may exaggerate the morphology of IPMN, and careful evaluation should be performed to select appropriate management.

Abstract
The increase of the morbidity rate in age-related diseases, such as cancer, Alzheimer's disease, arteriosclerosis and pulmonary fibrosis, has become a profound social problem. Recent reports have pointed out that senescent cells accumulated in the body with aging might cause these aged-related pathologies. Cellular senescence is known as an irreversible cell cycle arrest induced by various stresses, and can function as an important tumor suppression mechanism to exclude the premalignant cells. In contrast, senescent cells provoke the phenomenon, termed the senescence-associated secretory phenotype, which causes the secretion of various inflammatory proteins, and it is at risk of facilitating chronic inflammation and oncogenic transformation to surrounding cells. We have previously reported that senescent cells secrete not only inflammatory proteins, but also extracellular vesicles (EV). EV include various cellular components, such as proteins, lipids and nucleic acids, which are proven to be important factors for cell-to-cell communication. Recent evidence suggests that EV secreted from senescent cells might contribute to tumorigenesis and age-associated pathologies as new senescence-associated secretory phenotype factors. In addition, we also showed that the EV secretion pathway is one of the essential defense mechanisms to maintain cellular homeostasis by excretion of intercellular toxic substances into extracellular space. Herein, this review shows the biological functions of EV secreted from senescent cells. Geriatr Gerontol Int 2020; ••: ••-••.

Abstract
Chronic periodontitis (ChP) is a prevalent inflammatory disease affecting 46% of the US population. ChP produces a profound local inflammatory response to dysbiotic oral microbiota that leads to destruction of alveolar bone and tooth loss. ChP is also associated with systemic illnesses, including cardiovascular diseases, malignancies, and adverse pregnancy outcomes. However, the mechanisms underlying these adverse health outcomes are poorly understood. In this prospective cohort study, we used a highly multiplex mass cytometry immunoassay to perform an in-depth analysis of the systemic consequences of ChP in patients before (n = 28) and after (n = 16) periodontal treatment. A high-dimensional analysis of intracellular signaling networks revealed immune system-wide dysfunctions differentiating patients with ChP from healthy controls. Notably, we observed exaggerated proinflammatory responses to Porphyromonas gingivalis-derived lipopolysaccharide in circulating neutrophils and monocytes from patients with ChP. Simultaneously, natural killer cell responses to inflammatory cytokines were attenuated. Importantly, the immune alterations associated with ChP were no longer detectable 3 wk after periodontal treatment. Our findings demarcate systemic and cell-specific immune dysfunctions in patients with ChP, which can be temporarily reversed by the local treatment of ChP. Future studies in larger cohorts are needed to test the boundaries of generalizability of our results.

Abstract
The family Endornaviridae includes viruses with linear, single-stranded, positive-sense RNA genomes that range from 9.7 to 17.6 kb and have been reported infecting plants, fungi and oomycetes. The family consists of two genera, Alphaendornavirus and Betaendornavirus, into which viruses are classified based on their genome size, host and presence of unique domains. Alphaendornavirus includes species whose members infect plants, fungi and oomycetes, while the genus Betaendornavirus includes species whose members infect ascomycete fungi. This is a summary of the ICTV Report on the family Endornaviridae, which is available at www.ictv.global/report/endornaviridae.

Abstract
Treatment containing FOLFIRINOX was planned to be administered to a 51-year-old man with locally advanced pancreatic cancer as second-line chemotherapy and to a 66-year-old woman with recurrent pancreatic cancer as third-line chemotherapy in their treatments. Since both patients were revealed to harbor UGT1A1 polymorphisms, which were highly associated with irinotecan-induced toxicity(the former: UGT1A1 *6/*28, the latter: UGT1A1*6/*6), there was no alternative hopeful treatment other than FOLFIRINOX for them. Therefore, FOLFIRINOX was administered very carefully. Although both patients showed Grade 4 neutropenia during the initial course, it was controllable with G-CSF administration and following stepwise reduction of the irinotecan dose. Severe diarrhea and other adverse events were not observed in both cases. Since the determined regimen of FOLFIRINOX for patients with high-risk UGT1A1 polymorphisms has not been developed yet, it would be critical to accumulate and review an experience of FOLFIRINOX administration for these patients.

Abstract
The identification of novel biomarkers for hepatocellular carcinoma (HCC) is of great importance in improving the outcome of patients with HCC. The present study aimed to determine the prognostic significance of the soluble intercellular adhesion molecule (sICAM)-1 in patients with HCC. The present study prospectively collected clinicopathological data from 36 patients with HCC who had undergone successful hepatectomy. An analysis using a receiver operating characteristic (ROC) curve was performed to determine the cut-off value for predicting prognosis. Overall survival (OS), recurrence-free survival (RFS) and potential prognostic factors were analyzed. The ROC curve analysis revealed a sICAM-1 cut-off value of 440 ng/ml. HCC patients with sICAM-1 ≥440 ng/ml exhibited a poorer OS and RFS than those with sICAM-1 <440 ng/ml (P=0.002). sICAM-1 ≥440 ng/ml (hazard ratio=3.623; 95% confidence interval: 1.145-11.458; P=0.028) and Child B (hazard ratio=1.514; 95% confidence interval: 1.066-2.150; P=0.021) were independent prognostic factors for OS, and sICAM-1 ≥440 ng/ml was an independent prognostic factor for RFS (hazard ratio=3.625; 95% confidence interval: 1.233-10.659; P=0.019). Serum sICAM-1 may be a promising predictor for the overall and recurrence-free survival of patients with HCC.

Abstract
This study examines the interaction between gender and classroom social goal structures and the impact they have on children's prosocial behaviors and classroom adjustment. Specifically, classroom social goal structures (consisting of prosocial and compliance goal structure) are the degree to which focal social goals are presented in classrooms. Numerous previous studies have tested the gender differences in social outcomes; however, the results of such past studies have been mixed, as some detected gender differences while others did not. This suggests the existence of moderator variables. Consequently, in this research, we focused on classroom-level moderators in the relationship between gender and social outcomes. We analysed a sample of 3,609 Japanese public elementary school children from 114 classrooms, and we detected the presence of cross-level interactions and found that classroom social goal structures can promote or degrade boys' social outcomes.

Abstract
Pancreatic metastatic tumors from thyroid carcinoma are extremely rare. We report a case of an 80-year-old female with a pancreatic metastatic tumor derived from papillary thyroid carcinoma which was initially resected 158 months prior to detection of the metastatic pancreatic tumor. The patient has encountered cervical lymph-node metastasis on three occasions following the initial operation. Metastatic pancreatic lesions and cervical lymph nodes were first detected using 18-fluorodeoxyglucose positron-emission tomography/computed tomography, and she was preoperatively diagnosed using endoscopic ultrasound-guided fine-needle aspiration biopsy. A coin lesion, 10 mm in size, was detected in the left lung by chest computed tomography with no abnormal uptake in 18-fluorodeoxyglucose positron-emission tomography/computed tomography. Distal pancreatectomy and cervical lymph-node dissection were performed. Adjuvant chemotherapy with weekly paclitaxel was administered because anaplastic transformation had been detected in one of the cervical lymph nodes. The patient eventually died from multiple lung metastases 11 months after removing the metastatic pancreatic lesion. We reported a rare case of a pancreatic metastatic tumor from thyroid carcinoma, and found that 18-fluorodeoxyglucose positron-emission tomography/computed tomography and endoscopic ultrasound-guided fine-needle aspiration biopsy are useful for preoperatively diagnosing tumors.

Abstract
Cluster bean (Cyamopsis tetragonoloba), also called guar, is a drought-tolerant annual legume. We conducted investigations to characterize a large dsRNA (~13-14 kbp) detected in a symptomless cluster bean genotype. The dsRNA was gel-purified and used for Illumina MiSeq sequencing. Reads were assembled, and BLASTx search results showed sequence similarity with viruses classified within the family Endornaviridae. The complete sequence of the putative endornavirus consisted of 12,895 nt and contained an open reading frame which coded for a polyprotein of 4,207 aa with conserved domains for methyltransferase, helicase, and RNA-dependent RNA polymerase. The virus was named cluster bean endornavirus 1 (CBEV-1). A BLASTx search using the polyprotein sequence showed that the closest endornavirus to CBEV-1 was Hordeum vulgare endornavirus.

Abstract
BACKGROUND Liver fibrosis is a risk factor for hepatectomy but cannot be determined accurately before hepatectomy because diagnostic procedures are too invasive. Magnetic resonance elastography (MRE) can determine liver stiffness (LS), a surrogate marker for assessing liver fibrosis, non-invasively. The aim of this study was to investigate whether the LS value determined by MRE is predictive of major complications after hepatectomy. METHODS This prospective study enrolled consecutive patients who underwent hepatic resection between April 2013 and August 2016. LS values were measured by imaging shear waves by MRE in the liver before hepatectomy. The primary endpoint was major complications, defined as Clavien-Dindo grade IIIa or above. Logistic regression analysis identified independent predictive factors, from which a logistic model to estimate the probability of major complications was constructed. RESULTS A total of 96 patients were included in the study. Major complications were observed in 15 patients (16 per cent). Multivariable logistic analysis confirmed that higher LS value (P = 0·021) and serum albumin level (P = 0·009) were independent predictive factors for major complications after hepatectomy. Receiver operating characteristic (ROC) analysis showed that the best LS cut-off value was 4·3 kPa for detecting major complications, comparable to liver fibrosis grade F4, with a sensitivity of 80 per cent and specificity of 82 per cent. A logistic model using the LS value and serum albumin level to estimate the probability of major complications was constructed; the area under the ROC curve for predicting major complications was 0·84. CONCLUSION The LS value determined by MRE in patients undergoing hepatectomy was an independent predictive factor for major complications.

Abstract
A double-stranded RNA (dsRNA) mycovirus was detected in a strain of Alternaria alternata showing impaired growth phenotypes. The A. alternata strain is the Japanese pear pathotype, which produces a host-specific AK-toxin. Sequence analysis of the viral genome dsRNAs revealed that this mycovirus consists of five dsRNAs and is evolutionarily related to members of the family Chrysoviridae; the virus was named Alternaria alternata chrysovirus 1 (AaCV1). AaCV1-ORF2 protein accumulated in dsRNA-high-titer sub-isolates with severely impaired phenotypes; heterologous AaCV1-ORF2 overexpression in Saccharomyces cerevisiae caused growth inhibition. In contrast to this yeast growth inhibition phenomenon, the dsRNA-high-titer isolates displayed enhanced pathogenicity against Japanese pear plants, in accordance with a 13-fold increase in AK-toxin level in one such isolate. These findings indicated that AaCV1 is a novel mycovirus that exhibits two contrasting effects, impairing growth of the host fungus while rendering the host 'hypervirulent' to the plant.

Abstract
Accumulating evidence indicates that the senescence-associated secretory phenotype (SASP) contributes to many aspects of physiology and disease. Thus, controlling the SASP will have tremendous impacts on our health. However, our understanding of SASP regulation is far from complete. Here, we show that cytoplasmic accumulation of nuclear DNA plays key roles in the onset of SASP. Although both DNase2 and TREX1 rapidly remove the cytoplasmic DNA fragments emanating from the nucleus in pre-senescent cells, the expression of these DNases is downregulated in senescent cells, resulting in the cytoplasmic accumulation of nuclear DNA. This causes the aberrant activation of cGAS-STING cytoplasmic DNA sensors, provoking SASP through induction of interferon-β. Notably, the blockage of this pathway prevents SASP in senescent hepatic stellate cells, accompanied by a decline of obesity-associated hepatocellular carcinoma development in mice. These findings provide valuable new insights into the roles and mechanisms of SASP and possibilities for their control. Activation of DNA damage response induces the acquisition of senescence-associated secretory phenotype (SASP) in senescent cells, but precise mechanisms remain unclear. Here, the authors show that the cytoplasmic accumulation of nuclear DNA activated cytoplasmic DNA sensors to provoke SASP.

Abstract
Type-2 bitter-taste receptors (TAS2Rs) are important for the evaluation of food quality and the nutritional control in animals. Mutations in some TAS2Rs including TAS2R38 are known to increase susceptibility to various diseases. However, the involvement of TAS2Rs in cancers has not been well understood. We conducted a pilot study by genotyping two TAS2R genes, TAS2R38 and TAS2R46, in Japanese cancer patients diagnosed with the following types of cancer: biliary tract cancer, hepatocellular carcinoma, pancreatic cancer, colorectal cancer and gastric cancer. We selected the two TAS2Rs because they carry virtually non-functional alleles in human populations. We found that cancer risk is not associated with any TAS2R46 genotypes since there were no significant differences in genotype frequencies between cancer patients and controls. On the other hand, we confirmed that phenylthiocarbamide (PTC) non-tasters homozygous (AVI/AVI) for TAS2R38 were more frequent among Japanese cancer patients than those among controls as suggested in a previous study. The AVI/AVI genotype was therefore considered to increases cancer risk. In contrast, we also found that homozygous (PAV/PAV) PTC tasters are less frequent among cancer patients, suggesting that the PAV/PAV is a cancer resistant genotype that decreases cancer risk. Genotype frequencies for heterozygous AVI/PAV genotype were not significantly different between the two groups. It is suggested that the risk and resistance of cancers is antagonistically controlled by the two TAS2R38 alleles, PAV and AVI, rather than by the AVI allele alone.

Abstract
We hereby report a case of long-term survival of metastatic and recurrent duodenal gastrointestinal stromal tumor(GIST) treated with multimodality managements. A 59-year-old man was diagnosed with duodenal GIST and underwent surgical resection of a primary lesion of the duodenum. Since the pathological findings on mitotic rate indicated its high risk of recurrence, the systemic treatment by imatinib mesylate was given shortly after the surgery. Six months later, metastatic lesions being considered to be imatinib-resistant were observed in the remnant liver. Since there were no other drugs available for GISTs in clinic at that time, surgery of central bisegmentectomy with partial resection of the liver was performed to eliminate all metastatic lesions. However, recurrences had been repeatedly diagnosed afterward. In response to them, four more surgery for recurrent liver or peritoneal tumors, two transcatheter arterial chemoembolizations(TACE)and one radiofrequency ablation(RFA)were performed on the basis of its resectability. Sunitinib malate had been given since it was approved for imatinib-resistant GISTs in clinic. Eventually, as long as 99 months had passed since we observed the first evidence of the resistance to imatinib mesylate when he died from the GIST.

Abstract
OBJECTIVE The objective of this study is to investigate the role of cathepsin H (CatH), a lysosomal cysteine protease, in the development of experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. METHODS EAE was induced in CatH-deficient mice (CatH-/-) and wild-type littermates (+/+) using myelin oligodendrocyte glycoprotein (MOG) 35-55. The effects of CatH deficiency were determined by clinical scoring, mRNA expression levels of Tbx21, Rorc and FoxP3, protein levels of poly(I:C)-induced toll-like receptor 3 (TLR3) and phosphorylation of IRF3, and secretion of interferon-β (IFN-β) by splenocytes. RESULTS AND CONCLUSIONS CatH-/- showed a significantly earlier disease onset of EAE and increased Th1 cell differentiation in splenocytes. Splenocytes prepared from immunized CatH-/- showed a significant decrease in poly(I:C)-induced increased TLR3 expression, interferon regulatory factor 3 (IRF3) phospholylation and IFN-β secretion. Therefore, CatH deficiency impaired TLR3-mediated activation of IRF3 and consequent secretion of IFN-β from dendritic cells, leading to the enhancement of Th1 cell differentiation and consequent early disease onset of EAE.

Abstract
We hereby report a case of long-term survival of the pancreatic tail cancer with a synchronous small liver metastasis. A 62- year-old male with pancreatic tail cancer was incidentally diagnosed with single tiny metastasis in the left medial section of the liver duringthe distal pancreatectomy. The lesion was also resected together with primary lesion. Since then, systemic chemotherapies such as gemcitabine(GEM)plus S-1 combination therapy, GEM alone therapy and S-1 alone therapy had been given to escape from recurrence. However, the recurrences were found in the liver at 21 months after surgery. Left hepatectomy was performed for metastatic lesions. Afterwards, proton radiation therapy was twice performed for the metastatic lesions in the liver which were unable to be removed by surgery alone. Partial resection of transverse colon was also needed to be performed for the bowel obstruction caused by recurrence on the surgical margin of the liver. Systemic chemotherapies includingS -1 therapy, FOLFIRINOX therapy and GEM plus nab-paclitaxel therapy have been continued throughout his entire treatment history after recurrence. He has been keepingin good physical condition with these multidisciplinary therapies, even though 51 months have passed since the first evidence of liver metastasis was diagnosed.

Abstract
AIMS To elucidate the biological characteristics and stability of a newly identified staphylococcal enterotoxin Q (SEQ) against heating and digestive enzymes and to evaluate the risk of seq-harbouring Staphylococcus aureus in food poisoning. METHODS AND RESULTS Purified SEQ was treated with heating, pepsin and trypsin which are related to food cooking, stomach and intestine conditions, respectively. Superantigenic activity of SEQ was assessed by determining the ability of IL-2 induction in mouse spleen cells. The emetic activity of SEQ was assessed using house musk shrew, a small emetic animal model. The results revealed that SEQ exhibits a remarkable resistance to heat treatment and pepsin digestion and has significant superantigenic and emetic activities. Furthermore, a sandwich ELISA for detection of SEQ production was developed, and the results showed that seq-harboring S. aureus isolates produce a large amount of SEQ. CONCLUSIONS The newly identified SEQ had remarkable stability to heat treatment and digestive enzyme degradation and exhibited significant superantigenic and emetic activities. In addition, seq-harbouring S. aureus isolated from food poisoning outbreaks produced a large amount of SEQ, suggesting that seq-harbouring S. aureus could potentially be a hazard for food safety. SIGNIFICANCE AND IMPACT OF THE STUDY This study found, for the first time, that SEQ, a nonclassical SE, had remarkable stability to heat treatment and enzyme degradation and exhibited significant emetic activity, indicating that SEQ is a high-risk toxin in food poisoning.

Abstract
BACKGROUND/AIM Pancreatobiliary cancer is a disease associated with a dismal prognosis and limited treatment options. The aim of the present study was to clarify the usefulness of circulating galectin-3 in pancreatobiliary cancer. PATIENTS AND METHODS We examined serum galectin-3 concentrations in 45 patients with pancreatobiliary cancer. Receiver operating characteristic curves were utilized to evaluate the accuracy of circulating galectin-3 to discriminate pancreatobiliary cancer patients from controls and predict the prognostic outcomes. RESULTS Circulating galectin-3 had diagnostic value at the cut-off level of 6.2 ng/ml, and the patients' overall survival was predictable at the cut-off level of 10.3 ng/ml. Furthermore, circulating galectin-3 ≥10.3 ng/ml was an independent prognostic marker in pancreatobiliary cancer. Regarding biliary cancer, higher galectin-3 was associated with malnutrition. On the other hand, regarding pancreatic cancer, higher galectin-3 levels were associated with higher inflammatory parameters. CONCLUSION Galectin-3 can be a useful biomarker in patients with pancreatobiliary cancer.

Abstract
Acinar cell cystadenocarcinoma is a rare malignant epithelial neoplasm of the pancreas with a diffusely cystic, gross architecture in which the cysts are lined with neoplastic epithelial cells that demonstrate evidence of pancreatic exocrine enzyme production. This is the 10th case that has been reported in the literature. A 77-year-old male complaining of left hypochondrial pain was referred to our hospital for treatment of a pancreatic tumor. A huge, honeycomb-structured tumor was detected in the pancreatic tail. Distal pancreatectomy with total resection of the residual stomach and partial resection of the transverse colon were performed. Microscopically, there were variably sized cystic lesions in the tumor. Immunohistochemical examinations revealed that tumor cells were positive for alpha 1-antichymotrypsin and alpha 1-trypsin, showing that tumor cells had features of pancreatic acinar cells. Thus, the tumor was diagnosed as acinar cell cystadenocarcinoma. Herein, we report a rare case with acinar cell cystadenocarcinoma, which is the 10th case reported in the literature based on a PubMed search. We managed to resect the tumor completely by distal pancreatectomy with total resection of the residual stomach and partial resection of the transverse colon. The patient is still alive 26 months after surgery without any recurrence after 1 year of adjuvant chemotherapy with S-1.
