Abstract
Background/Aim There have been many studies on skeletal muscle depletion before surgery, and skeletal muscle depletion is a known risk factor for poor prognosis. However, reports on the association between changes in skeletal muscle mass and prognosis after surgery for pancreatic cancer are very few. Patients and Methods The data of 137 patients who underwent pancreatectomy for pancreatic cancer between 2005 and 2022 were reviewed. Muscle areas were measured at the third lumbar vertebral level, and skeletal muscle mass index (SMI) reduction rates were calculated. Patients were divided into two groups using receiver operating characteristic (ROC) curve analysis based on the SMI reduction rate with a cutoff of 14% reduction rate. The clinicopathological factors, overall survival (OS), and recurrence-free survival (RFS) were compared between the two groups. Survival rates were analyzed both univariately and multivariately to clarify the factors associated with poor prognosis after pancreatectomy. Results A total of 102 patients met the inclusion criteria. SMI reduction rate ≥14% significantly correlated with advanced age and higher incidence of postoperative complications. In the multivariate Cox regression analysis, preoperative prognostic nutritional index (PNI) <40 and SMI reduction rate ≥14% were significantly associated with poor OS. Tumor size ≥3.0 cm, preoperative neutrophile-lymphocyte ratio ≥3.0, and SMI reduction rate ≥14% were significantly associated with poor RFS. Conclusion The rate of skeletal muscle mass reduction after pancreatic surgery is an independent prognostic factor for survival in patients with pancreatic cancer.

Abstract
The observation of amyloid-β (Aβ) lesions using autofluorescence in transgenic mice and human Alzheimer disease patients has been reported frequently. However, no reports verify the autofluorescence of spontaneous Aβ amyloidosis in animals, to our knowledge. We validated the autofluorescence of Aβ lesions in spontaneous squirrel monkey cases under label-free conditions; lesions had intense blue-white autofluorescence in fluorescence microscopy using excitation light at 400-440 nm. Thioflavin S staining and immunohistochemistry of the same specimens revealed that this blue-white autofluorescence was derived from Aβ lesions. Hyperspectral analysis of these lesions revealed a characteristic spectrum with bimodal peaks at 440 and 460 nm, as reported for Aβ lesions in mice. Principal component analysis using hyperspectral data specifically separated the Aβ lesions from other autofluorescent substances, such as lipofuscin. A non-labeled and mechanistic detection of Aβ lesions by hyperspectral imaging could provide valuable insights for developing early diagnostic techniques.

Abstract
Reactive lymphoid hyperplasia (RLH) of the liver is extremely rare. Despite advancements in diagnostic imaging technology, it is still difficult to distinguish from hepatocellular carcinoma (HCC). Herein, we present a case of hepatic RLH mimicking HCC that was postoperatively diagnosed using several imaging modalities. A 78-year-old female was referred to our hospital with a positive hepatitis C virus antibody (HCV Ab) test. Ultrasonography revealed a 13 mm isoechoic lesion in segment 8 of the liver. Contrast-enhanced computed tomography (CE-CT) demonstrated arterial hyperintensity and washout during the later phase. On ethoxybenzyl magnetic resonance imaging (EOB-MRI), the lesion was hyperenhanced in the arterial phase and of low intensity in the hepatocyte phase. Although the tumor markers were all within normal limits, the pattern of contrast enhancement of the tumor on CT and MRI was consistent with that of HCC. We performed S8 segmentectomy of the liver. Histological examination of the resected specimen revealed dense lymphoid tissue of variable sizes and shapes with expanded germinal centers. Immunohistochemical examination was positive for CD3, CD10 (germinal center), and CD20, and negative for B-cell lymphoma 2 (bcl-2) (germinal center) and Epstein-Barr virus (EBV). A polymerase chain reaction (PCR) analysis of IgH-gene rearrangements revealed polyclonality. Based on these findings, hepatic RLH was diagnosed. The postoperative course was uneventful, and the patient was discharged on the 10th postoperative day. She had a good quality of life after surgery and no liver nodule recurrence was detected at the 4-month medical follow-up. Hepatic RLH is an extremely rare disease and preoperative diagnosis is difficult. This should be considered in the differential diagnosis of single small hepatic tumors. An echo-guided biopsy and careful observation of imaging may help diagnose hepatic RLH, and a PCR analysis of IgH-gene rearrangements would be necessary for the definitive diagnosis of hepatic RLH.

Abstract
The patient was a 33-year-old female. She was referred to our hospital from a previous clinic with abdominal pain and vomiting. Contrast-enhanced abdominal CT revealed intussusception, leading to a diagnosis of intussusception with a small intestinal tumor as an advanced part. Intestinal obstruction symptoms were observed, and emergency surgery was performed on the same day. As a technique, single port surgery was selected, and laparoscopic reduction was attempted. However, it was ineffective. The site of intussusception was induced outside the body through a small laparotomy wound, and reduction was performed using Hutchinson's procedure. As an adjacent lymph node was markedly swollen, the mesentery involving this lymph node was dissected in a fan shape, and the tumor was extirpated. The tumor measured 40 mm in long diameter, being a hemicircular, protruding lesion. Histologically, disarray of short spindle tumor cells was observed. Immunostaining showed Kit- and DOG1-negtive reactions and partially α-SMA and desmin-positive reactions, suggesting leiomyosarcoma. With the establishment of an immunostaining-test-based classification, leiomyosarcoma is currently rare. In this study, we report a patient in whom single port surgery for intussusception related to small intestinal leiomyosarcoma was successful.

Abstract
Hyperscanning is a form of neuroimaging experiment where the brains of two or more participants are imaged simultaneously whilst they interact. Within the domain of social neuroscience, hyperscanning is increasingly used to measure inter-brain coupling (IBC) and explore how brain responses change in tandem during social interaction. In addition to cognitive research, some have suggested that quantification of the interplay between interacting participants can be used as a biomarker for a variety of cognitive mechanisms aswell as to investigate mental health and developmental conditions including schizophrenia, social anxiety and autism. However, many different methods have been used to quantify brain coupling and this can lead to questions about comparability across studies and reduce research reproducibility. Here, we review methods for quantifying IBC, and suggest some ways moving forward. Following the PRISMA guidelines, we reviewed 215 hyperscanning studies, across four different brain imaging modalities: functional near-infrared spectroscopy (fNIRS), functional magnetic resonance (fMRI), electroencephalography (EEG) and magnetoencephalography (MEG). Overall, the review identified a total of 27 different methods used to compute IBC. The most common hyperscanning modality is fNIRS, used by 119 studies, 89 of which adopted wavelet coherence. Based on the results of this literature survey, we first report summary statistics of the hyperscanning field, followed by a brief overview of each signal that is obtained from each neuroimaging modality used in hyperscanning. We then discuss the rationale, assumptions and suitability of each method to different modalities which can be used to investigate IBC. Finally, we discuss issues surrounding the interpretation of each method.

Abstract
PURPOSE/OBJECTIVE(S) Complete resection of borderline resectable pancreatic cancer (BRPC) is difficult because of its invasion to the vital vessels. Although neoadjuvant therapy is recommended for BRPC, its optimal regimens remain unclear. Neoadjuvant chemoradiotherapy using moderately hypofractionated intensity-modulated radiotherapy (NAC-MH-IMRT) has potentials to improve the treatment outcomes with shorter treatment periods. Therefore, we evaluated the outcomes for BRPC patients treated with NAC-MH-IMRT. MATERIALS/METHODS Between February 2013 and June 2021, patients with BRPC treated with NAC-MH-IMRT at our institution were evaluated. All patients were classified as BRPC-A and BRPC-V according to NCCN guidelines. Information regarding patient status, tumor and treatment characteristics, margin-negative resection (R0) rates, histological effects assessed by Evans classification, and outcomes were obtained from the clinical records. Overall survival (OS) and progression-free survival (PFS) were calculated by the Kaplan-Meier method from the start date of any first treatment for BRPC. Toxicity was evaluated by CTCAE version 5.0. RESULTS Sixty-eight patients were included in this study (Table). All patients underwent induction chemotherapy, and 67 were treated with IMRT at 42 Gy in 15 fractions with concurrent gemcitabine (for 65) or S-1 (for 2). All patients achieved completion of radiotherapy. Fifty-seven of the 68 patients (83.8%) underwent surgical exploration, and 48 patients (70.6%) had a resection. The R0 resection was achieved in 44 patients, and the R0 resection rate was 91.7% in resected patients. Therapeutic effects by Evans classification showed as below: Grade 1/2a/2b/3/4 = 6 (12.5%)/17 (35.4%)/17 (35.4%)/7 (14.6%)/1 (2.1%). Adjuvant chemotherapy was performed for 41 patients, and S-1 and gemcitabine were used for 40 and 1 patient(s), respectively. The median follow-up time and median survival time (MST) were 23.6 months and 42.7 months, and 2-year OS and PFS were 67.3% and 30.2%, respectively. Recurrence was observed in 54 patients (79.4%), and the first recurrence pattern was as follows: 7 (13.0%)/42 (77.8%)/5 (9.3%) patients had local recurrence, distant metastases, and both of them, respectively. Regarding ≥ Grade 3 gastrointestinal toxicity related NAC-MH-IMRT, grade 3 ileus was observed in 1 patient. CONCLUSION NAC-MH-IMRT for BRPC showed preferable outcomes and acceptable toxicities with high completion rate.

Abstract
There are great expectations for artificial intelligence (AI) in medicine. We aimed to develop an AI prognostic model for surgically resected non-small cell lung cancer (NSCLC). This study enrolled 1049 patients with pathological stage I-IIIA surgically resected NSCLC at Kyushu University. We set 17 clinicopathological factors and 30 preoperative and 22 postoperative blood test results as explanatory variables. Disease-free survival (DFS), overall survival (OS), and cancer-specific survival (CSS) were set as objective variables. The eXtreme Gradient Boosting (XGBoost) was used as the machine learning algorithm. The median age was 69 (23-89) years, and 605 patients (57.7%) were male. The numbers of patients with pathological stage IA, IB, IIA, IIB, and IIIA were 553 (52.7%), 223 (21.4%), 100 (9.5%), 55 (5.3%), and 118 (11.2%), respectively. The 5-year DFS, OS, and CSS rates were 71.0%, 82.8%, and 88.7%, respectively. Our AI prognostic model showed that the areas under the curve of the receiver operating characteristic curves of DFS, OS, and CSS at 5 years were 0.890, 0.926, and 0.960, respectively. The AI prognostic model using XGBoost showed good prediction accuracy and provided accurate predictive probability of postoperative prognosis of NSCLC.

Abstract
In this report, we disclose our discovery of a new antifungal natural product, sakurafusariene (1), from an in-house fractionated library of the culture broth of Fusarium sp. FKI-7550 strain by using a combination strategy of multidrug-sensitive yeast and chemical modification. Throughout our investigation, we encountered challenges in the isolation of natural product 1. A chemical modification strategy via alkylation of 1 allowed for removal of the impurities enabling us to elucidate the structure of 1. Furthermore, we synthesized ester derivatives using a method inspired by the isolation study of 1, which gave us valuable information to understand a preliminary structure-activity relationship against Pyricularia oryzae growth inhibitory activity.

Abstract
G-protein-coupled receptors (GPCRs) are pivotal cell membrane proteins that sense extracellular molecules and activate cellular responses. The G-protein α subunit i (Gαi) family represents the most common GPCR-coupling partner and consists of eight subunits with distinct signaling properties. However, analyzing the coupling pattern has been challenging owing to endogenous expression of the Gαi subunits in virtually all cell lines. Here, we generate a HEK293 cell line lacking all Gαi subunits, which enables the measurement of GPCR-Gαi coupling upon transient re-expression of a specific Gαi subunit. We profile Gαi-coupling selectivity across 11 GPCRs by measuring ligand-induced inhibitory activity for cAMP accumulation. The coupling profiles are then classified into three clusters, representing those preferentially coupled to Gαz, those to Gαo, and those with unapparent selectivity. These results indicate that individual Gαi-coupled GPCRs fine-tune Gαi signaling by exerting coupling preference at the Gαi-subunit level.

Abstract
OBJECTIVES Sarcopenia correlates with poor prognosis in various malignancies. However, the prognostic significance of sarcopenia remains to be determined in patients with non-small-cell lung cancer who undergo surgery after receiving neoadjuvant chemoradiotherapy (NACRT). METHODS We retrospectively reviewed the patients with stage II/III non-small-cell lung cancer who underwent surgery following NACRT. The paravertebral skeletal muscle area (SMA) (cm2) at the 12th thoracic vertebra level was measured. We calculated the SMA index (SMAI) as SMA/squared height (cm2/m2). Patients were divided into low and high SMAI groups, and the association of SMAI with clinicopathological factors and prognosis was assessed. RESULTS The patients' [men, 86 (81.1%)] median age was 63 (21-76) years. There were 106 patients including 2 (1.9%), 10 (9.4%), 74 (69.8%), 19 (17.9%) and 1 (0.9%) patients with stage IIA, IIB, IIIA, IIIB and IIIC, respectively. Of the patients, 39 (36.8%) and 67 (63.2%) were classified in the low and the high SMAI groups, respectively. Kaplan-Meier analysis showed that the low group had a significantly shorter overall survival and disease-free survival than the high group. Multivariable analysis identified low SMAI as an independent poor prognostic factor for overall survival. CONCLUSIONS Pre-NACRT SMAI correlates with poor prognosis; therefore, assessing sarcopenia based on pre-NACRT SMAI may help determine optimal treatment strategies and suitable nutritional and exercise interventions.

Abstract
Transient receptor potential (TRP) channels are activated by various extracellular and intracellular stimuli and are involved in many physiological events. Because compounds that act on TRP channels are potential candidates for therapeutic agents, a simple method for evaluating TRP channel activation is needed. In this study, we demonstrated that a transforming growth factor alpha (TGFα) shedding assay, previously developed for detecting G-protein-coupled receptor (GPCR) activation, can also detect TRP channel activation. This assay is a low-cost, easily accessible method that requires only an absorbance microplate reader. Mechanistically, TRP-channel-triggered TGFα shedding is achieved by both of a disintegrin and metalloproteinase domain-containing protein 10 (ADAM10) and 17 (ADAM17), whereas the GPCR-induced TGFα shedding response depends solely on ADAM17. This difference may be the result of qualitative or quantitative differences in intracellular Ca2+ kinetics between TRP channels and GPCRs. Use of epidermal growth factor (EGF) and betacellulin (BTC), substrates of ADAM10, improved the specificity of the shedding assay by reducing background responses mediated by endogenously expressed GPCRs. This assay for TRP channel measurement will not only facilitate the high-throughput screening of TRP channel ligands but also contribute to understanding the roles played by TRP channels as regulators of membrane protein ectodomain shedding.

Abstract
Smoking is one of the risk factors most closely related to the severity of coronavirus disease 2019 (COVID-19). However, the relationship between smoking history and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infectivity is unknown. In this study, we evaluated the ACE2 expression level in the lungs of current smokers, ex-smokers, and nonsmokers. The ACE2 expression level of ex-smokers who smoked cigarettes until recently (cessation period shorter than 6 months) was higher than that of nonsmokers and ex-smokers with a long history of nonsmoking (cessation period longer than 6 months). We also showed that the efficiency of SARS-CoV-2 infection was enhanced in a manner dependent on the angiotensin-converting enzyme 2 (ACE2) expression level. Using RNA-seq analysis on the lungs of smokers, we identified that the expression of inflammatory signaling genes was correlated with ACE2 expression. Notably, with increasing duration of smoking cessation among ex-smokers, not only ACE2 expression level but also the expression levels of inflammatory signaling genes decreased. These results indicated that smoking enhances the expression levels of ACE2 and inflammatory signaling genes. Our data suggest that the efficiency of SARS-CoV-2 infection is enhanced by smoking-mediated upregulation of ACE2 expression level.

Abstract
Purpose Dynamic morphological changes in the chromosome and cytoskeleton occur in mammals and humans during early embryonic development, and abnormalities such as embryonic chromosomal aneuploidy occur when development does not proceed normally. Visualization of the intracellular organelles and cytoskeleton allows elucidation of the development of early mammalian embryos. The behavior of the DNA and cytoskeleton in early mammalian embryos has conventionally been observed by injecting target molecule mRNAs, incorporating a fluorescent substance-expressing gene, into embryos. In this study, we visualized the chronological behavior of male and female chromosome condensation in mouse embryos, beginning in the two-pronuclear zygote, through the first division to the two-cell stage, using fluorescent chemical probes to visualize the behavior of DNA, microtubules, and microfilaments. Method Mouse two-pronuclear stage embryo were immersed in medium containing fluorescent chemical probes to visualize DNA, microtubules, and microfilaments. Observation was performed with a confocal microscope. Results This method allowed us to observe how chromosome segregation errors in first somatic cell divisions in mouse embryos and enabled dynamic analysis of a phenomenon called lagging chromosomes. Conclusions By applying this method, we can observe any stage of embryonic development, which may provide new insights into embryonic development in other mammals.

Abstract
PURPOSE Pheochromocytoma crisis is a life-threatening endocrine emergency that requires prompt diagnosis and treatment. Because of its rarity, sudden onset, and lack of internationally uniform and validated diagnostic criteria, pheochromocytoma crisis remains to be fully clarified. Therefore, we aimed to describe the clinical characteristics and outcomes of pheochromocytoma crisis through a literature review. METHODS We performed a systematic literature search of PubMed/MEDLINE database, Igaku-Chuo-Zasshi (Japanese database), and Google Scholar to identify case reports of pheochromocytoma crisis published until February 5, 2021. Information was extracted and analyzed from the literature that reported adequate individual patient data of pheochromocytoma crisis in English or Japanese. Cases were also termed as pheochromocytoma multisystem crisis (PMC) if patients had signs of hyperthermia, multiple organ failure, encephalopathy, and labile blood pressure. RESULTS In the 200 cases of pheochromocytoma crisis identified from 187 articles, the mean patient age was 43.8 ± 15.5 years. The most common symptom was headache (39.5%). The heart was the most commonly damaged organ resulting from a complication of a pheochromocytoma crisis (99.0%), followed by the lungs (44.0%) and the kidney (21.5%). PMC accounted for 19.0% of all pheochromocytoma crisis cases. After excluding 12 cases with unknown survival statuses, the mortality rate was 13.8% (26/188 cases). Multivariable logistic regression analysis revealed that nausea and vomiting were significantly associated with a higher mortality rate. CONCLUSION Pheochromocytoma can present with different symptomatology, affecting different organ systems. Clinicians should be aware that patients with nausea or vomiting are at a higher risk of death because of pheochromocytoma crisis.

Abstract
BACKGROUND Extrapulmonary tuberculosis commonly affects the lymphatic system, nervous system, and gastrointestinal system. Tuberculous infection in the muscle is very rare. Moreover, tuberculous infection in the diaphragm is extremely rare. We herein report a case of tuberculomas in the diaphragm and posterior mediastinum that were successfully diagnosed and treated. CASE PRESENTATION We encountered a 62-year-old woman with a tuberculoma in the diaphragm. The patient presented with mild dyspnea. Computed tomography showed a mass in the left diaphragm, focal thickening of the posterior mediastinum, and multiple nodules in the lungs. Positron emission tomography-computed tomography showed increased uptake in the left diaphragm mass and thickening of the posterior mediastinum; therefore, we considered the masses to be malignant and planned surgical resection. However, the patient was diagnosed with tuberculosis from a sputum culture, and she was treated with anti-tuberculous therapy. The masses in the diaphragm and posterior mediastinum had become enlarged after 6 months of anti-tuberculous therapy; therefore, the patient underwent resection of both masses. Tuberculous infection was histologically confirmed in each lesion. She was pathologically diagnosed with tuberculous abscesses in the diaphragm and posterior mediastinum and began treatment with anti-tuberculosis drugs. CONCLUSIONS Preoperative diagnosis of a tuberculoma in the diaphragm is usually difficult, and surgical intervention is important for both diagnosis and treatment.

Abstract
Abstract
Background
The lymphatic system has been suggested to play an important role in cardiovascular diseases including heart failure (HF). Vascular endothelial growth factor C (VEGF-C) and D (VEGF-D) are key regulators of lymphangiogenesis, and we recently reported the association of low VEGF-C with the risk of all-cause death and high VEGF-D with the risk of HF hospitalization in patients with HF.
Purpose
To investigate the association of VEGF-C and VEGF-D with prognosis in patients with HF with preserved ejection fraction (EF) (HFpEF: EF≥50%), mildly reduced EF (HFmrEF: EF, 40–49%), and reduced EF (HFrEF: EF<40%).
Methods
The PREHOSP-CHF study is a multicenter prospective cohort study to determine the predictive value of angiogenesis-related biomarkers in HF. A total of 1,024 patients (mean age 75.5±12.6 years; 58.7% male) admitted to acute decompensated HF were included in the analyses. Serum levels of VEGF-C and VEGF-D, as well as N-terminal pro B-type natriuretic peptide (NT-proBNP), high sensitivity cardiac troponin-I (hs-cTnI), high sensitivity C reactive protein, were measured at the time of discharge. Patients were followed-up over two years.
Results
The numbers of HFpEF, HFmrEF, and HFrEF were 429 (41.9%), 186 (18.2%), and 409 (39.9%), respectively. HFpEF patients were older, more likely to be female, and had more hypertension, atrial fibrillation, and anemia, but less coronary artery disease. NT-proBNP and hs-cTnI levels increased with decreasing EF. VEGF-C levels decreased with increasing EF (median [interquartile range]: HFpEF, 4508 [3318–5919] pg/ml; HFmrEF, 4719 [3663–6203] pg/ml; HFrEF, 5023 [3804–6382] pg/ml), whereas VEGF-D levels were comparable among the three EF groups (HFpEF, 404.6 [293.1–560.3] pg/ml; HFmrEF, 386.0 [298.5–556.3] pg/ml; HFrEF, 414.2 [296.1–557.3] pg/ml). In multivariate stepwise logistic regression analyses, anemia and high NT-proBNP were independently associated with low VEGF-C levels, and high NT-proBNP was independently associated with high VEGF-D levels, across all the EF groups. During the follow-up, incidences of all-cause death and HF hospitalizations were similar among the three EF groups (log-rank P=0.6 for all-cause death, and log-rank P=0.3 for HF hospitalization). On multivariate Cox proportional hazard analyses including established risk factors and cardiovascular biomarkers, VEGF-C levels tended to be inversely associated with the incidence of all-cause death in patients with HFpEF and HFrEF (Figure). On the contrary, VEGF-D levels were significantly and positively associated with the incidence of HF hospitalization in patients with HFpEF, and tended to be positively associated with it in patients with HFmrEF and HFrEF (Figure).
Conclusions
Low VEGF-C was associated with the risk of all-cause death in patients with HFpEF and HFrEF, while high VEGF-D was associated with the risk of HF hospitalization especially in HFpEF.

Abstract
Background Systemic artery to pulmonary vessel fistula (SAPVF) is an uncommon abnormal vascular communication between systemic arteries and the lung parenchyma. It has been reported that the appropriate treatment for SAPVF is embolization or surgical resection. However, in patients such as ours, who have many aberrant vessels or multiple lesions, surgery should be considered as the first-choice treatment. Case presentation This case report describes multiple SAPVFs and huge bullae at the apex of the left lung in a 43-year-old man that were resected completely with the video-assisted thoracoscopic surgery (VATS). The patient had an uneventful postoperative recovery without any complications and was discharged 9 days postoperatively. He had heavy smoking history, and the giant bullae and the diffuse emphysematous change were found in the lung. Therefore, the chronic inflammation may have been present in the thoracic cavity, which caused multiple SAPVFs. Conclusions We describe the clinical course and management of the patient with multiple SAPVFs who had no obvious history of surgery, trauma, or various inflammatory or infection diseases. VATS should be the first-choice treatment in patients with many abnormal vessels or multiple lesions.

Abstract
BACKGROUND Preoperative maximum standardized uptake value (SUVmax) of 2-[18F]-fluoro-2-deoxy-D-glucose positron emission tomography and serum carcinoembryonic antigen (CEA) have been reported as prognostic factors for lung adenocarcinoma. However, the significance of combined SUVmax and CEA in early-stage lung adenocarcinoma is not well known. METHODS We retrospectively evaluated the relationship between the combination of SUVmax and CEA and the prognosis of 410 patients with clinical stage IA lung adenocarcinoma who underwent resection. The cutoff values for SUVmax and CEA were determined by receiver operating characteristic curve analysis, and patients were categorized into high SC (SUVmax and CEA) group (SUVmax ≥2.96 and CEA ≥5.3), moderate SC group (either SUVmax <2.96 and CEA ≥5.3 or SUVmax ≥2.96 and CEA <5.3) and low SC group (SUVmax <2.96 and CEA <5.3). RESULTS Kaplan-Meier curve analysis showed that patients with clinical stage IA lung adenocarcinoma in the high SC group had significantly shorter overall survival (OS) and recurrence-free survival (RFS) than the other groups (p = 0.011 and p < 0.0001, respectively). Multivariate analysis showed that high SC was an independent prognostic factor of OS (p = 0.029) and RFS (p < 0.0001). CONCLUSIONS High values of SUVmax and CEA were associated with poor OS and RFS in patients with stage IA lung adenocarcinoma. Simultaneous evaluation of SUVmax and CEA may be an effective prognostic marker to determine the optimal treatment strategy of early-stage lung adenocarcinoma.

Abstract
Background Consolidation tumor ratio (CTR) is associated with cancer progression and histological invasiveness in lung adenocarcinoma (LAD). However, little is known about the association between CTR and immune‐related factors, including tumor‐infiltrating lymphocytes (TILs) density or tumor expression of programmed death ligand 1 (PD‐L1) and indoleamine 2,3‐dioxygenase 1 (IDO1) in small‐sized LAD. Methods This study included 258 patients with LAD (<3 cm) who underwent surgery. Patients were assigned to four groups: CTR = 0; 0 < CTR <0.5; 0.5 ≤ CTR <1 (ground‐glass opacity [GGO] group); and CTR = 1 (pure‐solid group). CD4+, CD8+, and FoxP3+ TIL density and PD‐L1 and IDO1 tumor expression were assessed by immunohistochemistry. Results Among the GGO group, CD8+ and FoxP3+ TIL density increased significantly with increasing CTR (p < 0.001 and p < 0.001, respectively). Moreover, PD‐L1 and IDO1 expression was significantly higher in the pure‐solid group than in the GGO group (p < 0.001 and p < 0.001, respectively). Conclusions CTR was correlated with the abundance of CD8+ and FoxP3+ TILs in the GGO group. PD‐L1 and IDO1 positivity rates were significantly higher in the pure‐solid group than in the GGO group. Increased CTR may be correlated with immunosuppressive condition.

Abstract
BackgroundTocilizumab (TCZ) is a humanized anti-IL-6 receptor monoclonal antibody that improves the signs and symptoms of rheumatoid arthritis (RA). In previous clinical trials, long-term outcomes have been increasingly evaluated in daily clinical practice. We report the five-year outcomes of TCZ treatment at our institute.ObjectivesThis retrospective study determined the long-term trends in TCZ use in clinical practice.MethodsData from the Toyohashi RA database (TRAD) were used. The TRAD is single-center retrospective data. Last observation carried forward was used as a complementary method for missing data. Participants were 59 RA patients in whom TCZ therapy was started at our institute from September 2009 to May 2016. Subsequent items, baseline patient characteristics, disease activity, treatment continuation rates of TCZ using the Kaplan-Meier method, reasons for stopping TCZ, concomitant use of methotrexate (MTX) and prednisolone (PSL) were investigated.ResultsBaseline characteristics at the start of TCZ treatment were 17 men and 42 women with a mean age of 58.6 years (30–81). The mean RA duration was 8.7 years (0–31). The mean SDAI score was 27.9 ± 11.6; the mean DAS28-CRP was 5.0 ± 1.0. CRP was 4.1 ± 3.0 mg/dl and MMP-3 388.3 ± 311.5 ng/ml. Methotrexate (MTX) was administered in 37 patients (62.7%, mean 6.0 mg, mean MTX dose administered in cases, 9.6 mg/week). Prednisolone (PSL) was administered in 37 patients (62.7%, mean 3.6 mg; the mean PSL dose administered in cases 5.7 mg/day).Regarding disease activity, the mean SDAI was 27.9 at baseline; 12.3 at three months; 8.1 at one year; 7.3 at two years; 6.5 at three years; 46.7 at four years; 5.6 at five years, and 5.2 at final observation. The SDAI significantly improved after two years compared to baseline. Remission and low disease activity also significantly improved at one year and gradually improved after one year (Figure 1). The remission rate at the final observation was 55.2%, with an SDAI ≦3.3.TCZ continuation rates were 86.9% at one year, 78.7% at three years, and 68.9% at five years (Figure 2). TCZ was discontinued due to adverse events in 11 cases (18%), and inadequate efficacy occurred in 9 (14.8%). The adverse events were respiratory infection (5), purulent arthritis (1), infectious endocarditis (1), subarachnoid hemorrhage (1), breast cancer (1), pruritis (1), and skin ulcer (1). Other reasons for discontinuation were dialysis (2), suspension of hospital visits (2), kidney transplant (1), and financial difficulties (1). Concomitant use from baseline to final observation declined from 62.7% to 15.3% for MTX and from 62.7% to 23.7% for PSL.ConclusionLong-term treatment with TCZ was acceptable. We found that with TCZ therapy, the remission and low disease activity rates significantly improved at one year and continued to improve after one year. Treatment persistence was high, but careful monitoring for infection is necessary.Disclosure of InterestsNone declared

Abstract
BackgroundAlthough biological drugs have dramatically changed and improved the outcome of patients with rheumatoid arthritis (RA), a lot of unresolved problems still exist. Although comorbidity by which enough treatment drugs cannot be prescribed or RA patients refractory to biological agents are representatives, financial difficulty is another representative. There are RA patients who hesitate biological treatment or treatment with Janus-kinase inhibitor due to financial difficulty. Although biosimilar disease-modifying anti-rheumatic drugs (DMARDs) are promising treatment options for such patients, real-world clinical experiences are still lacking in respect to exchanging from biological originator DMARDs to biosimilar DMARDs.ObjectivesThis retrospective study investigated the effects of switching from etanercept originator (ETN-OR) to ETN biosimilar (ETN-BS: LBEC0101 developed by LG Chem) on disease activity, physical function, and patient reported outcome (PRO) regarding a self-injection device in patients with well-controlled RA.MethodsData from the Toyohashi RA Database (TRAD) was used, which is a collection of single-center retrospective data. We retrospectively investigated disease activity, modified health assessment questionnaire (mHAQ), and patient characteristics in 42 RA patients that switched from ETN-OR to ETN-BS at least 6 months prior. Patients were also requested to answer the Toyohashi Self-Injection Assessment Questionnaire (T-SAQ), originally designed to assess PRO. T-SAQ consisted of 18 questions about self-injection device such as burden, learning, pain, convenience, handling and so on. Best was 0 and worst was 4 in each question and mean score of 18 questions was called total T-SAQ score. ResultsAll the patients were female. The mean age, RA duration, and ETN-OR treatment duration were 63.1 years, 18.3 years, and 3107 days, respectively. Mean disease activity and mean mHAQ after switching were as follows (baseline-3 months-6): DAS28-CRP (1.86-2.00-2.03), SDAI (4.3-5.0-5.3), and mHAQ (0.43-0.44-0.46). SDAI after 6 months was significantly elevated compare to baseline. Among each parameter, tender joints count at 3 months and patients’ global assessment at 6 months after switching are significantly increased compared to baseline (Table 1). Other parameters such as swollen joint counts, physician global assessment and CRP were not significantly changed. Total T-SAQ scores before and after switching were 1.3 and 1.1 (p < 0.01), respectively. Ease of use, mental tension, and pain were especially improved after switching to ETN-BS.ConclusionSwitching from ETN-OR to ETN-BS worsened disease activity in well-controlled RA patients in our real-world clinical practice due to not objective findings, but subjective complaints by RA patient. We thought that nocebo effect was one of the reasons to explain the results. On the other hand, the PRO regarding the injection device was improved. This improvement may be due to Finer needle of ETN-BS (ETN-OR: 27G, ETN-OR: 29G).Disclosure of InterestsNone declared

Abstract
BackgroundRomosozumab (ROMO) is an antisclerostin antibody that is used in the treatment of severe osteoporosis (OP). In March 2019, ROMO was approved for use in Japan for treating severe OP in clinical practice, causing an increase in its prescription in our institute. Although efficacy data for ROMO have been presented in clinical trials, there is a lack of real-world data. In our experience, ROMO treatment results in significant bone mineral density (BMD) gain in some patients, but not all. Therefore, understanding the predictors that enhance the efficacy of ROMO treatments to achieve BMD gain is essential.ObjectivesThis study investigated the efficacy of a 12-month ROMO treatment in patients with OP and explored the efficacy predictors of increased BMD.MethodsOur study included 52 patients with OP, who were started on ROMO treatment between June 2019 and August 2020. The following information was collected: 1) baseline characteristics, 2) time-course of BMD (lumbar spine [LS] and total hip [TH]) and bone turnover markers (BTM; bone-specific alkaline phosphatase [BAP], type I procollagen-N-propeptide [P1NP], type I procollagen-N-propeptide[NTX], and tartrate-resistant acid phosphatase-5b [TRACP-5b]), 3) multiple regression analysis results following Spearman’s correlation analysis of increased BMD values (%) at 12 months and BL characteristics, including BTM change (%) at one month, to investigate the efficacy predictors of ROMO.Results1) The mean age of the participants was 72.9 years (48 female and four male). Of the 52 understudied patients, 78.8% had past insufficiency fractures, whereas 21.2% had been treated with concomitant prednisolone. Furthermore, 21 patients had primary OP, 20 had rheumatoid arthritis, nine had glucocorticoid-induced OP, and two had other conditions. Pretreatments for OP were bisphosphonate (33 patients), vitamin D (6), none (5), selective estrogen receptor modulator (4), and denosumab (3).2) Both mean LS- and TH-BMD significantly increased in the patients for whom ROMO administration was continued for 12 months. The average percentage changes of LS- and TH-BMD were 7.1% and 1.6% at six months and 11.7% and 3.0% at 12 months, respectively (Figure 1). However, BAP and P1NP increased steeply at one month, followed by a gradual decrease. As observed, the average percentage changes of BAP and P1NP were +70.1% and +166.8% at one month, +50.3% and +91.7% at six months, and +24.4% and +41.5% at 12 months, respectively. The results also showed that TRACP-5b decreased from one to 12 months, with the average percentage changes being −22.9% at one month, −13.8% at six months, and −17.7% at 12 months. Moreover, NTX, a bone-resorptive marker, was slightly increased during ROMO treatment.3) Multiple regression analysis results revealed that the baseline BAP and percentage calcium changes at 12 months were significant factors positively correlated with the percentage change of LS-BMD at 12 months. As observed, the baseline T-score of LS-BMD was a significant factor negatively correlated with the percentage change of LS-BMD at 12 months. The standardized partial regression coefficient values were +0.68, +0.26, and −0.40, respectively. Moreover, the multiple regression analysis results revealed no significant factor that was correlated with the percentage changes of TH-BMD at 12 months.Figure 1.ConclusionROMO treatments rapidly increased BMD, especially LS-BMD, and changed BTM after one month. Baseline BAP were correlated with increased LS-BMD but not with TH-BMD. The factors correlated with increased BMD may differ between LS-BMD and TH-BMD.Disclosure of InterestsNone declared

Abstract
BackgroundOsteoporosis (OP) is a frequent complication identified in patients with rheumatoid arthritis (RA). Effective treatment must be provided to treat OP in RA (RAOP). Denosumab (DMB) is a promising drug, currently being used for the treatment of RAOP. Although DMB was determined to be effective in a long-term FREEDOM extension trial [1] for treating postmenopausal OP, its efficacy in the treatment of RAOP in real-world is not be fully evaluated.ObjectivesThis retrospective study assessed the five-year treatment outcome of DMB in Japanese patients with RAOP.MethodsData from the Toyohashi RA Database (TRAD) was used, which is a collection of single-center retrospective data. Our study included 65 female patients with RAOP for whom DMB treatment was initiated between October 2013 and May 2016. The following information was collected: 1) baseline characteristics, 2) DMB continuation rates using the Kaplan–Meier method and reasons for stopping DMB, 3) fracture occurrence during DMB treatment, and 4) time-course of bone mineral density (BMD) [lumbar spine (LS) and total hip (TH)] and bone turnover markers (BTM) [bone-specific alkaline phosphatase (BAP), type I procollagen-N-propeptide (P1NP), type I procollagen-N-propeptide (NTX), and tartrate-resistant acid phosphatase-5b (TRACP-5b)] in 38 patients who underwent DMB treatment over a period of five years.Results1) The mean age and RA duration were 69.4 years (46–86) and 17.2 years (1–49), respectively. Prednisolone and biologics were administered in 21 (32.3%) and 20 (30.8%) patients, respectively. Twenty-seven patients (41.5%) had a history of fragility fractures, and 24 patients (36.9%) had a history of vertebral fractures. Pretreatment drugs for OP were as follows: bisphosphonate in 22 patients; teriparatide, 17; none, 16; activated vitamin D, 7; and selective estrogen receptor modulator, 3.2) Continuation rates of DMB were 96.9% at one year, 95.4% at two years, 85.8% at three years, 79.4% at four years, and 71.1% at five years. DMB treatment was terminated in 24 patients due to lack of efficacy in nine patients, death in seven patients (unknown reason in four, pneumonia in two, and senile decay in one), adverse events except death in five patients (worsening of dementia in two, brain hemorrhage in one, necrosis of jaw in one, and pneumonia in one), and other reasons in three patients.3) Nine patients (13.8%) experienced fractures during DMB treatment; vertebral and non-vertebral fractures occurred in three and four patients, respectively. Two cases of fractures remained undefined.4) Both mean LS-BMD and TH-BMD significantly increased in 38 patients for whom DMB administration was continued for five years. Average percent changes of LS-BMD and TH-BMD were 3.9% and 3.0% at six months, 5.5% and 3.8% at one year, 7.6% and 4.1% at two years, 9.8% and 5.7% at three years, 10.8% and 6.5% at four years, and 12.9% and 6.8% at five years (Figure 1). Four BTMs, BAP, P1NP, NTX, and TRACP-5b, significantly decreased from six months to five years when compared to baseline values, with average changes at 5 years equaling −38.4%, −37.8%, −23.8%, and −24.6%, respectively.ConclusionDMB treatment of RAOP proved effective and reasonably safe, and it increased BMD by a percentage similar to that observed in the FREEDOM extension trial. However, DMB administration was ceased in 13.8% of cases due to fractures and lack of efficacy. Although DMB is recommended for the treatment of RAOP, future evaluations should be conducted to predict its efficacy and determine alternative treatment strategies.References[1]Bone HG et al.

Abstract
Abstract
Real-time diagnostics of ceramic powder injection molding using a commercial micromolding machine was performed using ultrasound. Miniature ultrasonic sensors were integrated onto the mold insert. Melt front, solidification, temperature variation and part detachment of the feedstock inside the mold cavity were observed. It has been demonstrated that ultrasonic velocity in feedstock inside the mold cavity, the ultrasonic contact duration during which the part and mold are in contact, and holding pressure can be used to assist with optimization of injection and cooling parameters to minimize energy consumption and maximize process efficiency.

Abstract
Non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations is highly sensitive to EGFR-tyrosine kinase inhibitor (EGFR-TKI). However, few cases of advanced NSCLC completely cured by EGFR-TKIs have been reported. We present an extremely rare case of lung adenocarcinoma that was completely cured by gefitinib administration. A 36-year-old Japanese woman was diagnosed with clinical Stage IIIB (T2N3M0) lung adenocarcinoma originating from the left upper lobe in April 2006. After the two cycles of chemotherapy, it was down-staged to ycStage IA (T1N0M0). She underwent a thoracotomy with left upper lobectomy, pulmonary angioplasty, and mediastinal nodal dissection in July 2006 [ypStage IIIA (T3N1M0)]. Eighteen months later, she was found to have lymphadenopathy of the right supraclavicular nodes. Fine needle aspiration cytology of the lymph node indicated adenocarcinoma. She started gefitinib therapy for recurrent lung cancer with EGFR mutation (exon 19 deletion) in January 2008. Four months afterward, computed tomography (CT) showed her right supraclavicular nodes had shrunk dramatically. Treatment with gefitinib was continued. Thereafter, no disease progression was observed throughout her approximately 8-year gefitinib treatment, and gefitinib was terminated in November 2016. Although the patient received no other treatment, she has suffered no recurrence in the 4 years since. A review of the literature, including our case, is also presented.

Abstract
Signaling-biased ligands acting on G-protein-coupled receptors (GPCRs) differentially activate heterotrimeric G proteins and β-arrestins. Although a wealth of structural knowledge about signaling bias at the GPCR level exists (preferential engagement of a specific transducer), little is known about the bias at the transducer level (different functions mediated by a single transducer), partly due to a poor understanding of GPCR kinase (GRK)-mediated GPCR phosphorylation. Here, we reveal a unique role of the Gq heterotrimer as a determinant for GRK-subtype selectivity that regulates subsequent β-arrestin conformation and function. Using the angiotensin II (Ang II) type-1 receptor (AT1R), we show that β-arrestin recruitment depends on both GRK2/3 and GRK5/6 upon binding of Ang II, but solely on GRK5/6 upon binding of the β-arrestin-biased ligand TRV027. With pharmacological inhibition or genetic loss of Gq, GRK-subtype selectivity and β-arrestin functionality by Ang II is shifted to those of TRV027. Single-molecule imaging identifies relocation of AT1R and GRK5, but not GRK2, to an immobile phase under the Gq-inactive, AT1R-stimulated conditions. These findings uncover a previously unappreciated Gq-regulated mechanism that encodes GRK-subtype selectivity and imparts distinct phosphorylation-barcodes directing downstream β-arrestin functions. GPCR kinases (GRKs) phosphorylate active-form G-protein-coupled receptors (GPCRs). Here, the authors reveal that Gq heterotrimer coupled with the angiotensin II type-1 receptor (AT1R) determines the GRK subtypes recruited to the complex in a microdomain, thus defining subsequent AT1R phosphorylation patterns, β-arrestin conformation and functionality.

Abstract
Abstract
Background
The lymphatic system has been suggested to play an important role in cardiovascular (CV) diseases including heart failure (HF). Vascular endothelial growth factor C (VEGF-C) and VEGF-D are key regulators of lymphoangiogenesis.
Purpose
To investigate the association of VEGF-C and VEGF-D with prognosis in patients with chronic HF (CHF).
Methods
The PREHOSP-CHF study is a multicenter prospective cohort study to determine the predictive value of angiogenesis-related biomarkers in CHF. A total of 1,024 patients (mean age, 75.5±12.6 years; male, 58.7%) admitted to acute decompensated HF were included in the analyses. The primary outcome was MACE defined as a composite of CV death or HF hospitalization. The secondary outcomes were all-cause death, CV death, and HF hospitalizations. Serum levels of VEGF-C and VEGF-D, as well as N-terminal pro B-type natriuretic peptide (NT-proBNP), high sensitivity cardiac troponin-I (hs-cTnI), high sensitive C reactive protein (hs-CRP), VEGF, and soluble VEGF receptor-2 (sVEGFR-2) were measured at the time of discharge. Patients were followed-up over two years.
Results
Median [interquartile range] of VEGF-C and VEGF-D levels were 4821 [3633–6131] pg/ml and 404 [296–559] pg/ml, respectively. In multivariate stepwise regression analysis, independent determinants of VEGF-C levels were younger age, female gender, absence of prior HF hospitalization, chronic kidney disease, and anemia, lower ejection fraction, lower NT-proBNP levels, higher VEGF levels, and higher sVEGFR-2 levels, while those of VEGF-D levels were lower body mass index, presence of diabetes and atrial fibrillation, and higher NT-proBNP levels. During the follow-up, a total of 209 (20.4%) all-cause deaths, 112 (10.9%) CV deaths, and 309 (30.2%) HF hospitalizations occurred. After adjusting for established risk factors and CV biomarkers, VEGF-C levels were significantly and inversely associated with the incidence of MACE and non-CV death (Fig.1, model 4). On the other hand, VEGF-D levels were significantly and positively associated with the incidence of HF hospitalization (Fig. 1, model 4). When we divided the patients into 4 groups based on the median of VEGF-C and VEGF-D levels, patients with low VEGF-C and high VEGF-D showed significantly higher incidence of MACE, all-cause death, CV death, and HF hospitalization compared to those with high VEGF-C and low VEGF-D (Fig. 2).
Conclusions
Among patients with CHF, VEGF-C and VEGF-D had different characteristic and association with the incidence of adverse events. VEGF-C levels were inversely associated with the incidence of MACE and non-CV death, and VEGF-D levels were positively associated with the incidence of HF hospitalization. These results suggests different effects of VEGF-C and VEGF-D in CHF. Combination of VEGF-C and VEGF-D enables us to make good risk stratification in patients with CHF.

Abstract
Amyloidosis is diagnosed by the histologic detection of amyloid deposits; however, this method has limitations such as a prolonged diagnosis time and the need for histologic proficiency. We aimed to develop a rapid and simple method for diagnosing amyloidosis by targeting amyloid-specific endogenous fluorescence, which has not been reported previously, to our knowledge. Fluorescence fingerprint analysis of amyloid extracts and tissue homogenates derived from amyloid A (AA) amyloidosis-affected cattle exhibited a specific intrinsic fluorescence pattern. Furthermore, principal component analysis using analytical data revealed that AA could be identified by peaks near λex 350 nm and λem 430 nm. Fluorescence spectrometry analysis using tissue homogenates, which does not require special histochemical staining, enables the rapid detection of bovine AA.

Abstract
This research proposes a relationship between two methods such as a numerical approach by conducting a microtremor array observation and field survey by using the seismic cone penetration test unit (SCPTu). A database of shear-wave velocity (Vs) measurements was established using the microtremor array technique and seismic cone penetration test unit (SCPTu) on high-quality samples of rock and soft soil in Padang city, Indonesia. The study also demonstrates that the Vs values obtained from the different methods are consistent with the microtremor array technique. This technique may thus be deemed a valuable tool, as it can be used in engineering practice with confidence. Comparison of the Vs for different soils at the first layer between the microtremor array observation results and the SCPTu results exhibited the microtremor array method is unable to determine the Vs at the layer where its Vs changes dramatically, such as at the same layer as station UNP at 2 to 3.5m deep.

Abstract
This prospective trial revealed the additional diagnostic value of staging laparoscopy with contrast-enhanced intraoperative ultrasonography and indocyanine green-fluorescence imaging, detecting radiologically occult liver metastases and other occult metastases effectively for patients with high-risk resectable or borderline resectable pancreatic cancer. The 2-year survival rate of patients without occult metastasis was significantly better than that of patients with occult metastasis. These favourable results for patients without occult metastasis indicate that an enhanced screening strategy and modern multidisciplinary treatment may improve the outcome even of patients affected by high-risk advanced pancreatic cancer.

Abstract
Soybean (Glycine max (L.) Merr.) plants form root nodules and fix atmospheric dinitrogen, while also utilizing the combined nitrogen absorbed from roots. In this study, nodulated soybean plants were supplied with 5 mM N nitrate, ammonium, or urea for 3 days, and the changes in metabolite concentrations in the xylem sap and each organ were analyzed. The ureide concentration in the xylem sap was the highest in the control plants that were supplied with an N-free nutrient solution, but nitrate and asparagine were the principal compounds in the xylem sap with nitrate treatment. The metabolite concentrations in both the xylem sap and each organ were similar between the ammonium and urea treatments. Considerable amounts of urea were present in the xylem sap and all the organs among all the treatments. Positive correlations were observed between the ureides and urea concentrations in the xylem sap as well as in the roots and leaves, although no correlations were observed between the urea and arginine concentrations, suggesting that urea may have originated from ureide degradation in soybean plants, possibly in the roots. This is the first finding of the possibility of ureide degradation to urea in the underground organs of soybean plants.

Abstract
BACKGROUND/AIM Albumin-bilirubin (ALBI) grade is an indicator of liver dysfunction and is useful for predicting postoperative prognosis of hepatocellular carcinomas. However, the significance of ALBI grade in non-small cell lung carcinoma (NSCLC) has not been elucidated. PATIENTS AND METHODS We analyzed 947 patients with pStage IA-IIIA NSCLC. We divided patients into ALBI grade 1 and grade 2/3 groups. We then analyzed the association of ABLI grade with clinicopathological characteristics and prognosis in NSCLC by using propensity-score matching. RESULTS ALBI grade 2/3 was significantly associated with older age, male sex, advanced pT status, and histological type. Even after propensity-score matching, ALBI grade 2/3 patients had significantly worse cancer-specific survival (CSS) than ALBI grade 1 patients (5-year CSS: 87.3% versus 92.8%; p=0.0247). In multivariate analysis, ALBI grade 2/3 was an independent predictor of CSS (HR=1.9; 95%CI=1.11-3.11; p=0.0177). CONCLUSION ALBI grade was an independent prognostic factor in surgically resected NSCLC.

Abstract
OBJECTIVE Sesamin is a functional ingredient in sesame (Sesamum indicum) seeds and has many physiological effects. This study investigated whether sesame lignans, sesamin and episesamin (1:1), can suppress age-related disorders of the kidney. MATERIALS AND METHODS Twenty-month-old mice were divided into three groups, and each group received a regular diet (O-C), diet containing sesame lignans (O-SE), and diet containing sesame lignans and α-tocopherol (VE; O-SE+VE), respectively, for 5 months. Six-month-old young mice (Y-C) were compared to the older mice. RESULTS Renal lipofuscin deposition was increased in the O-C group compared to that in the Y-C group and its deposition with aging was significantly decreased in both O-SE and O-SE+VE groups. Plasma blood urea nitrogen levels in the O-C group increased compared to those in the Y-C group; however, those in both O-SE and O-SE+VE groups did not differ from those in the Y-C group. The number of podocytes in the O-C group decreased compared to that in the Y-C group and this effect was attenuated in the O-SE and O-SE+VE groups. The effect was strongest in the O-SE+VE group. Histological examinations showed that glomerular hypertrophy accompanied by mesangial hyperplasia and renal tubular degeneration was less severe in the O-SE and O-SE+VE groups than in the O-C group. Moreover, age-related increases in the mRNA expression of NADPH oxidase- and inflammation-related genes, including p67phox, p40phox, TNFα, and IL-6, in the kidney were suppressed in the O-SE and O-SE+VE groups. CONCLUSIONS Sesame lignans might be useful to suppress age-related kidney disorders, and these effects could be enhanced with VE.

Abstract
Mechanisms that control mobilization of cytosolic calcium [Ca2+]i are key for regulation of numerous eukaryotic cell functions. One such paradigmatic mechanism involves activation of phospholipase Cβ (PLCβ) enzymes by G protein βγ subunits from activated Gαi-Gβγ heterotrimers. Here, we report identification of a master switch to enable this control for PLCβ enzymes in living cells. We find that the Gαi-Gβγ-PLCβ-Ca2+ signaling module is entirely dependent on the presence of active Gαq. If Gαq is pharmacologically inhibited or genetically ablated, Gβγ can bind to PLCβ but does not elicit Ca2+ signals. Removal of an auto-inhibitory linker that occludes the active site of the enzyme is required and sufficient to empower "stand-alone control" of PLCβ by Gβγ. This dependence of Gi-Gβγ-Ca2+ on Gαq places an entire signaling branch of G-protein-coupled receptors (GPCRs) under hierarchical control of Gq and changes our understanding of how Gi-GPCRs trigger [Ca2+]i via PLCβ enzymes.

Abstract
Leptomeningeal metastasis (LM) from lung cancer has poor prognosis, and effective therapy has not been established. We present the case of a 54-year-old man with LM from lung adenocarcinoma harboring EGFR L858R point mutation, who received osimertinib as first-line therapy. He had previously undergone left lower lobectomy and lymph node dissection for lung adenocarcinoma. Five years and 9 months after the operation, he developed symptoms of dizziness, lightheadedness, and headache. Magnetic resonance imaging showed high signal intensity in the cerebral sulcus and meninges, and cerebrospinal fluid (CSF) cytology indicated adenocarcinoma with EGFR L858R point mutation, which suggested LM. After CSF drainage and administration of corticosteroid and glycerol, the patient received osimertinib (80 mg/day) as first-line therapy. These symptoms including dizziness, lightheadedness, and headache were relieved and the MRI appearance was normal, and he survived for 19 months with no disease progression. Osimertinib is considered to be an effective therapeutic option for LM from lung adenocarcinoma harboring EGFR mutation.

Abstract
OBJECTIVE Sesamin is a major lignan constituent of sesame and possesses various health-promoting effects. Previous studies have demonstrated that sesamin extends the lifespan of Drosophila and Caenorhabditis elegans and corrects oxidative damage-related tissue dysfunction in mammals. To understand its anti-aging effects, we aimed to determine whether sesamin restores tissue function hampered by oxidative damage and suppresses several aging-related phenotypes using Drosophila senescence-accelerated models. MATERIALS AND METHODS We elucidated the anti-aging effects of sesamin on several aging-related phenotypes in the muscle, brain and midgut using the senescence-accelerated models (Sod1n1 mutant and Sod1-depleted flies) by immunostaining experiments. We determined the expression levels of several anti-oxidative and DNA repair genes using quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). We also identified the metabolite of sesamin in Drosophila by LC-MS/MS. RESULTS We confirmed that sesamin (0.35 and 2 mg/ml) extended the lifespan of the fly models. As observed in mammals, it can be absorbed and metabolized by Drosophila adults. The sesamin feeding suppressed the age-dependent impairment of locomotor activity and inhibited the accumulation of reactive oxygen species (ROS) in their bodies. Sesamin delayed the age-dependent accumulation of damaged proteins in the muscle, partially suppressed the loss of dopaminergic neurons in adult brains displaying ROS accumulation, and suppressed the accumulation of DNA damage and hyperproliferation of intestinal stem cells. Four antioxidative genes and two DNA repair genes were simultaneously upregulated in sesamin-fed adults. CONCLUSIONS: These observations represent the first direct evidence of the anti-aging effects of sesamin at the individual level. We propose that sesamin exerts anti-aging effects in the muscles, brain and midgut by inducing antioxidative and DNA repair genes, resulting in extended lifespan in flies.

Abstract
The hippocampus is functionally heterogeneous between the dorsal and ventral subfields with left–right asymmetry. To determine the possible location of contextual memory, we performed an inhibitory avoidance task to analyze synaptic plasticity using slice patch-clamp technique. The training bilaterally increased the AMPA/NMDA ratio at dorsal CA3–CA1 synapses, whereas the training did not affect the ratio at ventral CA3–CA1 synapses regardless of the hemisphere. Moreover, sequential recording of miniature excitatory postsynaptic currents and miniature inhibitory postsynaptic currents from the same CA1 neuron clearly showed learning-induced synaptic plasticity. In dorsal CA1 neurons, the training dramatically strengthened both excitatory and inhibitory postsynaptic responses in both hemispheres, whereas the training did not promote the plasticity in either hemisphere in ventral CA1 neurons. Nonstationary fluctuation analysis further revealed that the training bilaterally increased the number of AMPA or GABAA receptor channels at dorsal CA1 synapses, but not at ventral CA1 synapses, suggesting functional heterogeneity of learning-induced receptor mobility. Finally, the performance clearly impaired by the bilateral microinjection of plasticity blockers in dorsal, but not ventral CA1 subfields, suggesting a crucial role for contextual learning. The quantification of synaptic diversity in specified CA1 subfields may help us to diagnose and evaluate cognitive disorders at the information level.

Abstract
BACKGROUND Interleukin (IL)-38 was discovered in 2001 and is a member of the IL-1 family of cytokines. IL-38 shows anti-inflammatory activity in several inflammatory diseases. In lung adenocarcinoma, we previously demonstrated that high IL-38 expression in tumor cells was associated with poor prognosis. However, the role of IL-38 in the tumor microenvironment has not been clarified. METHODS IL-38-plasmid-transfected Lewis lung carcinoma cells (LLC-IL38) and empty vector-transfected LLC cells (LLC-vector) were established. Cell proliferation in vitro and tumor growth in vivo were examined, and immunohistochemical staining was used to assess tumor-infiltrating lymphocytes (TILs). A CD8+ lymphocyte depletion model was established to show the association between IL-38 and CD8+ lymphocytes. Moreover, we examined the association between IL-38 expression and CD8+ TILs in human samples, analyzing immunohistochemical staining in 226 patients with radically resected lung adenocarcinoma. RESULTS Tumor growth of LLC-IL38 in vivo was significantly increased compared with that of LLC-vector, although cell proliferation of LLC-IL38 in vitro was lower than that of LLC-vector. CD8+ TILs were significantly decreased in LLC-IL38 tumor compared with LLC-vector tumor. The difference in tumor growth between LLC-IL38 and LLC-vector became insignificant after depletion of CD8+ lymphocytes. In immunohistochemical staining in tissues from patients with lung adenocarcinoma, multivariate analysis showed high IL-38 expression was an independent negative predicter of high density of CD8+ TILs. CONCLUSION We demonstrated that high IL-38 expression in tumor cells was significantly associated with reduction of CD8+ TILs and tumor progression. These results suggest that IL-38 could be a therapeutic target for lung cancer.

Abstract
Beneficial effects of sesame lignans, especially antioxidative effects, have been widely reported; however, its potential effects on autonomic nerves have not yet been investigated. Therefore, the current study aimed to investigate the effect of sesame lignans on the autonomic nervous system. The sympathetic nerve activity in rat skeletal muscle was measured using electrophysiological approaches, with blood flow determined using the laser Doppler method. Sesame lignans were administered intragastrically at 2 and 20 mg/kg, and after 60 min, the sympathetic nerve activity was observed to increase by 45.2% and 66.1%, respectively. A significant increase in blood flow (39.6%) was also observed for the 20-mg/kg dose when measured at 55 min after administration. These sympathomimetic effects were completely prevented by subdiaphragmatic vagotomy, and the increase in blood flow was eliminated in the presence of the beta2-adrenergic receptor inhibitor butoxamine. Thus, it is proposed that sesame lignans can increase the blood flow of skeletal muscle, possibly by exciting sympathetic nerve activity through the afferent vagal nerve.

Abstract
Background Pancreatoduodenectomy (PD) with portal vein resection (PVR) is a standard operation for pancreatic ductal adenocarcinoma (PDAC) with portal vein (PV) invasion, but positive margin rates remain high. It was hypothesized that regional pancreatoduodenectomy (RPD), in which soft tissue around the PV is resected en bloc, could enhance oncological clearance and survival. Methods This retrospective study included consecutive patients who underwent PD with PVR between January 2005 and December 2016 in a single high‐volume centre. In standard PD (SPD) with PVR, the PV was skeletonized and the surrounding soft tissue dissected. In RPD, the retropancreatic segment of the PV was resected en bloc with its surrounding soft tissue. The extent of lymphadenectomy was similar between the procedures. Results A total of 268 patients were included (177 SPD, 91 RPD). Tumours were more often resectable in patients undergoing SPD (60·5 per cent versus 38 per cent in those having RPD; P = 0·014), and consequently they received neoadjuvant therapy less often (7·9 versus 25 per cent respectively; P < 0·001). R0 resection was achieved in 73 patients (80 per cent) in the RPD group, compared with 117 (66·1 per cent) of those in the SPD group (P = 0·016), although perioperative outcomes were comparable between the groups. Median recurrence‐free (RFS) and overall (OS) survival were 17 and 32 months respectively in patients who had RPD, compared with 11 and 21 months in those who had SPD (RFS: P = 0·003; OS: P = 0·004). Conclusion RPD is as safe and feasible as SPD, and may increase the survival of patients with PDAC with PV invasion.

Abstract
OBJECTIVE Low-density lipoprotein (LDL) oxidative susceptibility is recognized as a risk factor for atherosclerosis. We previously reported that the ingestion of a supplement containing sesame lignans (sesamin/episesamin) for 4 weeks reduced LDL oxidative susceptibility in humans. MATERIALS AND METHODS To elucidate the mechanisms underlying this observation, 12-week-old New Zealand White rabbits were fed a fat/cholesterol-enriched diet (100 g/day) for 6 weeks followed by oral administration of vehicle (control) or sesame lignans (50 mg/kg) for 4 weeks with the fat/cholesterol-enriched diet. RESULTS The results showed that the ingestion of sesame lignans prolonged LDL oxidation lag time, regardless of the existence of the anti-oxidative catechol metabolite of sesamin/episesamin in LDL. Plasma platelet-activating factor acetylhydrolase (PAF-AH) activity was significantly reduced by sesame lignans. The prolongation of LDL oxidation lag time was abolished by the addition of a PAF-AH inhibitor. The expression level of pro-inflammatory cytokines and macrophage infiltration observed in the liver following the feeding of the fat/cholesterol-enriched diet were also significantly reduced by sesame lignans. CONCLUSIONS These results indicate that sesame lignans reduce LDL oxidative susceptibility by downregulating plasma PAF-AH activity via the reduction of inflammation in the liver induced by fat/cholesterol-enriched diets.

Abstract
Immunoglobulin G4-related disease (IgG4-RD) is a fibroinflammatory condition which involves various organs. This is a very rare case of IgG4-related lung disease (IgG4-RLD) with the invasion into diaphragm. The patient was a 71-year-old man with a long-term exposure to asbestos who had a mass shadow in the left lower lung lobe, which was suspected to invade the left diaphragm on computed tomography (CT). Positron emission tomography (PET)/CT also presented an avid intake of fluorodeoxyglucose in the mass, which suspected lung cancer. Although bronchoscopic biopsy could not lead to the definite diagnosis, we performed left lower lobectomy combined with the resection of left diaphragm. The specimen showed the features of IgG4-RLD on pathology: the vein stenosis and fibrosis around the vein, the infiltration of IgG4-positive cells, and IgG cells to IgG4 cells ratio of 40%. Furthermore, there were inflammatory cells infiltrating to the diaphragm.

Abstract
WNT-Frizzled (FZD) signaling plays a critical role in embryonic development, stem cell regulation and tissue homeostasis. FZDs are linked to severe human pathology and are seen as a promising target for therapy. Despite intense efforts, no small molecule drugs with distinct efficacy have emerged. Here, we identify the Smoothened agonist SAG1.3 as a partial agonist of FZD6 with limited subtype selectivity. Employing extensive in silico analysis, resonance energy transfer- and luciferase-based assays we describe the mode of action of SAG1.3. We define the ability of SAG1.3 to bind to FZD6 and to induce conformational changes in the receptor, recruitment and activation of G proteins and dynamics in FZD–Dishevelled interaction. Our results provide the proof-of-principle that FZDs are targetable by small molecules acting on their seven transmembrane spanning core. Thus, we provide a starting point for a structure-guided and mechanism-based drug discovery process to exploit the potential of FZDs as therapeutic targets. WNT-Frizzled (FZD) signaling plays a critical role in embryonic development, tissue homeostasis and human disease but no small molecule drugs targeting FZD with distinct efficacy have emerged so far. Here, authors identify the Smoothened agonist SAG1.3 as a partial agonist for FZD6 with limited subtype selectivity.
