    Abstract: ... of adjuvant S-1 chemotherapy (ASC) for biliary tract cancer (BTC) after surgical resection ...

    Abstract Backgrounds: A recent randomized control trial (JCOG1202; ASCOT trial) demonstrated the efficacy of adjuvant S-1 chemotherapy (ASC) for biliary tract cancer (BTC) after surgical resection; however, the significance of the completion of ASC in the real-world setting remains unknown.
    Methods: Data of consecutive patients who underwent surgical resection for biliary tract cancer (BTC) from 2011 to 2021 were retrospectively reviewed. Of these, patients who underwent ASC were enrolled in this study. Patients were divided into two groups according to whether ASC was completed: the completion group and the non-completion group. Clinicopathological features and survival outcomes were assessed.
    Results: Of the 223 patients with BTC who underwent surgical resection, 75 patients who underwent ASC were included for analysis. Among them, 48 (64.0 %) completed the intended ASC course, while 27 cases (36.0 %) discontinued the treatment. The most common reason for the discontinuation was adverse event (n = 16, 59.3 %), followed by disease recurrence (n = 9, 33.3 %). Patients in the completion group showed significantly better overall survival (OS) (p < 0.001) and recurrence-free survival (RFS) (p < 0.001) compared to the non-completion group. Further, after excluding the patients in the non-completion group who discontinued ASC due to disease recurrence, the significance of ASC completion was retained for both OS and RFS.
    Conclusion: The completion of ASC was associated with improved prognosis in patients with BTC after surgical resection. The achievement of ASC should be the goal after surgical resection, while further study may be warranted regarding the resistance of ASC.

    Abstract Abstract Darwin’s naturalization conundrum describes two seemingly contradictory hypotheses regarding whether alien species closely or distantly related to native species should be more likely to naturalize in regional floras. Both expectations have accumulated empirical support, and whether such apparent inconsistency can be reconciled at the global scale is unclear. Here, using 219,520 native and 9,531 naturalized alien plant species across 487 globally distributed regions, we found a latitudinal gradient in Darwin’s naturalization conundrum. Naturalized alien plant species are more closely related to native species at higher latitudes than they are at lower latitudes, indicating a greater influence of preadaptation in harsher climates. Human landscape modification resulted in even steeper latitudinal clines by selecting aliens distantly related to natives in warmer and drier regions. Our results demonstrate that joint consideration of climatic and anthropogenic conditions is critical to reconciling Darwin’s naturalization conundrum.

    Abstract The prognosis of locally advanced gastric cancer is poor even if radical gastrectomy with D2 lymphadenectomy is followed by adjuvant chemotherapy. Hence, neoadjuvant chemotherapy is performed to try to improve the prognosis, as it can significantly downstage the tumor and safely improve the R0 resection rate of patients. Herein, we report a case of locally advanced gastric cancer with pancreatic invasion and gastric outlet obstruction that showed a pathological complete response after neoadjuvant chemotherapy with S-1 and oxaliplatin (SOX). A 74-year-old man presented to our hospital with abdominal pain and pyloric stenosis. CT images revealed a cStage IVb, cT4b tumor in the pancreas, cN1, cM0. Therefore, we performed laparoscopic gastrojejunostomy, and the patient's oral intake improved after surgery; we then administered neoadjuvant chemotherapy with SOX on postoperative day 18, without any surgical complications. After 3 courses of neoadjuvant chemotherapy, the patient underwent radical distal gastrectomy, thereby avoiding pancreatoduodenectomy. Histopathological examination of the resected sample revealed no residual cancer cells, indicating a pathological complete response. No recurrence has occurred for 1 year after surgery. Thus, neoadjuvant chemotherapy with SOX can help in tumor downstaging and may be a multipotent option for the treatment of locally advanced gastric cancer, such as cases with the invasion of other organs; this treatment can result in improved curability and avoid overinvasive surgery.

    Abstract Electrically conductive molecular junctions are highly desirable components for applications in future molecular-scale electronic circuits. Here, we demonstrate an electrically conductive hybrid molecular junction that consists of Au–S and Au−π bindings using a sumanene derivative with three phosphine–sulfide anchoring groups at the periphery of the sumanene backbone. The molecular junction was prepared between the Au electrodes by the scanning tunneling microscopy-based break junction method. The three anchoring groups and the sumanene backbone in the junction form the Au–S chemical bonds and Au−π direct bonds, respectively. The Au–S chemical binding immobilized the molecule on the Au electrode and provided the high mechanical stability of the junction, while the direct Au−π binding led to the large metal–molecule electric coupling and high electronic conductance of the molecular junction. This study analyzes the molecular design of the electrically conductive molecular junctions based on the hybrid binding groups.

    Abstract Abstract Background In developing countries, it is difficult to collect the data of the underlying cause of death (UCOD), especially when a death does not occur in a health facility. This study aimed to develop a short version of verbal autopsy (VA) and identify the UCOD of adults in Lao People’s Democratic Republic (Lao PDR). Methods A short version of VA for deaths outside health facilities was developed. This study included all deaths of people aged 15 years old or older in Xaiyabouli Province in 2020. Socio-demographic factors, place of death, and UCOD of the deceased were collected from health facilities or from family members using a questionnaire including the short VA form. UCOD was compared between home deaths and hospital deaths, between the age group of 15–59 years old and the age group ≥ 60 years old, and between males and females. Results Of all the 1,235 deaths included in this study, 1,012 deaths (81.9%) occured at home and 223 deaths (18.1%) at hospitals. The most common UCOD was senility (13.3%), followed by heart/renal failure (10.5%), pneumonia (9.6%) and traffic accident (7.1%). Compared to hospital deaths, home deaths had more people who were females, 75 years old or older, and Lao-Tai. Home deaths had more deaths than hospital deaths due to accident/injury (16.0% vs. 8.1%), tumor (4.7% vs. 1.8%), and senility (16.2% vs. 0%); fewer deaths due to heart/renal disease (15.1% vs. 32.3%), respiratory disease (12.2% vs. 18.8%), liver/gastro-intestine disease (5.3% vs. 9.0%), and infection (3.1% vs. 14.3%). The age group of 15–59 years had more deaths in the categories of accident/injury (28.1% vs. 4.4%), liver/gastro-intestine disease (8.1% vs. 4.4%), infection (7.2% vs. 3.5%), and tumor (6.0% vs. 2.8%). Males had more deaths due to tumor (5.2% vs. 3.0%) and fewer natural deaths (11.2% vs. 15.9%) than females. Conclusions The major UCOD category was heart/renal disease in the adult generation in Xaiyabouli Province. Cost-effective interventions based on the multisectoral noncommunicable disease ...

    Abstract Abstract The density of the solar wind plasma near the Earth’s magnetosphere sometimes decreases to only several per cent of the usual value, and such density extrema result in a significant reduction of the dynamic pressure and Alfvén Mach number ( $$M_A$$ M A ) of the solar wind flow. While a symmetric expansion of the Earth’s magnetosphere by the low dynamic pressure was assumed in previous studies, a global magnetohydrodynamic (MHD) simulation study predicted a remarkable dawn-dusk asymmetry of the magnetospheric shape under low-density solar wind and Parker-spiral interplanetary magnetic field (IMF) configuration. Here, we present observations consistent with the asymmetric deformation of the magnetosphere under low- $$M_A$$ M A solar wind and Parker-spiral IMF conditions, focusing on the significant expansion of the dawn-flank magnetosphere detected by the Geotail spacecraft. A global MHD simulation reproduced the dawnward expansion of the near-Earth magnetosphere, which was consistent with the observation by Geotail. The solar wind flow had a non-negligible dusk-to-dawn component and partly affected the dawnward expansion of the magnetosphere. Local, roughly Alfvénic sunward acceleration of magnetosheath ions at the dawn flank magnetopause suggests magnetosheath plasma entry into the magnetosphere through open field lines generated by magnetic reconnection at the dayside magnetopause. At the same time, Cluster 1 and 3, located near the southern polar cusp, also detected continuous antisunward ion jets and occasional sunward jets, which are consistent with the occurrence of magnetic reconnection near the southern cusp. These observations suggest that enhanced plasma acceleration at the dayside magnetopause operates under the low- $$M_A$$ M A solar wind and Parker spiral IMF conditions and that plasma influx across the dawnside magnetopause is at work under such a low- $$M_A$$ M A condition. These results can be helpful in understanding interactions between low- $$M_A$$ M A solar/stellar winds and celestial ...

    Abstract Glutathione S-transferase (GST) was found to complex with the Na⁺,K⁺-ATPase as shown by binding assay using quartz crystal microbalance. The complexation was obstructed by the addition of antiserum to the α-subunit of the Na⁺,K⁺-ATPase, suggesting the specificity of complexation between GST and the Na⁺,K⁺-ATPase. Co-immunoprecipitation experiments, using the anti-α-subunit antiserum to precipitate the GST-Na⁺,K⁺-ATPase complex and then using antibodies specific to an isoform of GST to identify the co-precipitated proteins, revealed that GSTπ was complexed with the Na⁺,K⁺-ATPase. GST stimulated the Na⁺,K⁺-ATPase activity up to 1.4-fold. The level of stimulation exhibited a saturable dose-response relationship with the amount of GST added, although the level of stimulation varied depending on the content of GSTπ in the lots of GST received from supplier. The stimulation was also obtained when recombinant GSTπ was used, confirming the results. When GST was treated with reduced glutathione, GST activity was greatly stimulated, whereas the level of stimulation of the Na⁺,K⁺-ATPase activity was similar to that when untreated GST was added. When GST was treated with H₂O₂, GST activity was greatly diminished while the stimulation of the Na⁺,K⁺-ATPase activity was preserved. The results suggest that GSTπ complexes with the Na⁺,K⁺-ATPase and stimulates the latter independent of its GST activity.

    Abstract: ... novel putative target genes for Alzheimer’s disease and successfully identified key genes that may serve ...

    Abstract Abstract Background Identifying novel therapeutic targets is crucial for the successful development of drugs. However, the cost to experimentally identify therapeutic targets is huge and only approximately 400 genes are targets for FDA-approved drugs. As a result, it is inevitable to develop powerful computational tools that can identify potential novel therapeutic targets. Fortunately, the human protein-protein interaction network (PIN) could be a useful resource to achieve this objective. Methods In this study, we developed a deep learning-based computational framework that extracts low-dimensional representations of high-dimensional PIN data. Our computational framework uses latent features and state-of-the-art machine learning techniques to infer potential drug target genes. Results We applied our computational framework to prioritize novel putative target genes for Alzheimer’s disease and successfully identified key genes that may serve as novel therapeutic targets (e.g., DLG4, EGFR, RAC1, SYK, PTK2B, SOCS1). Furthermore, based on these putative targets, we could infer repositionable candidate-compounds for the disease (e.g., tamoxifen, bosutinib, and dasatinib). Conclusions Our deep learning-based computational framework could be a powerful tool to efficiently prioritize new therapeutic targets and enhance the drug repositioning strategy.
