1094-408732142024Jul01Optics expressOpt ExpressAccurate two-dimensional simulation model and experimental demonstration in ultraviolet picosecond laser scribing ablation.240412405724041-2405710.1364/OE.524351Laser patterning of copper thin films is essential for the electronics manufacturing industry. In this work, to efficiently and accurately describe the physics process of UV-ps laser ablating copper thin film, a two-temperature model (TTM) consisting of the electron-lattice system and phase explosion mechanism was proposed. The process of electron heating and electron-lattice heat transfer in single pulse ablation were revealed. The average relative errors (ARE) of simulated ablation depth and width were 6.24% and 4.82%, respectively. The process of laser scribing ablation presents the characteristics of repeated ablation in the overlapping ablation region and new ablation in the non-overlapping region. The physics essence of laser scribing is the multiple laser ablations with different energies on the cross-section. The laser scribing cross-section ablation was simulated on 2D TTM. Compared with 3D simulation, though the ARE of ablation depth and width of 2D simulation slightly increased from 15.81% and 5.69% to 18.96% and 8.76%, respectively, the average solving time decreased significantly, from 81960 s to 2140 s. This comprehensive study aims to offer some insights into the characteristics of UV-ps laser ablation of copper thin film.XuZhiyingZZhaoNanNZhangCaijieCCaiShixianSWangKaiKWangKedongKLiJiamingJZhangQingmaoQYanXueqingXZhuKunKengJournal Article

1946-6242167722024Nov06Science translational medicineSci Transl MedIntegrative multiomic analysis identifies distinct molecular subtypes of NAFLD in a Chinese population.eadh9940eadh994010.1126/scitranslmed.adh9940Nonalcoholic fatty liver disease (NAFLD) has become a common health care burden worldwide. The high heterogeneity of NAFLD remains elusive and impairs outcomes of clinical diagnosis and pharmacotherapy. Several NAFLD classifications have been proposed on the basis of clinical, genetic, alcoholic, or serum metabolic analyses. Yet, accurately predicting the progression of NAFLD to cirrhosis or hepatocellular carcinoma (HCC) in patients remains a challenge. Here, on the basis of a Chinese cohort of patients, we classified NAFLD into three distinct molecular subtypes (NAFLD-mSI, NAFLD-mSII, and NAFLD-mSIII) using integrative multiomics including whole-genome sequencing (WGS), proteomics, phosphoproteomics, lipidomics, and metabolomics across a broad range of liver, blood, and urine specimens. We found that NAFLD-mSI had higher expression of CYP1A2 and CYP3A4, which alleviate hepatic steatosis through mediating free fatty acid/bile acid-mTOR-FXR/PPARα signaling. NAFLD-mSII displayed an elevated risk of liver cirrhosis along with increased hepatic infiltration of M1 and M2 macrophages because of lipid-triggered hepatic CCL2 and CRP production. NAFLD-mSIII exhibited a potential risk for HCC development by increased transcription of CEBPB- and ERCC3-regulated oncogenes because of activation of the EGF-EGFR/CHKA/PI3K-PDK1-AKT cascade. Next, we validated the existence of these three NAFLD molecular subtypes in an external cohort comprising 92 patients with NAFLD across three different Chinese hospitals. These findings may aid in understanding the molecular features underlying NAFLD heterogeneity, thereby facilitating clinical diagnosis and treatment strategies with the aim of preventing the development of liver cirrhosis and HCC.DingJingjingJ0000-0003-1508-7084Department of Gastroenterology, the First Affiliated Hospital (Southwest Hospital), Third Military Medical University (Army

1527-33502024Jul10Hepatology (Baltimore, Md.)HepatologyHepatic GDP-fucose transporter SLC35C1 attenuates cholestatic liver injury and inflammation by inducing CEACAM1 N153 fucosylation.10.1097/HEP.0000000000001003Inflammatory response is crucial for bile acid (BA)-induced cholestatic liver injury, but molecular mechanisms remain to be elucidated. Solute Carrier Family 35 Member C1 (SLC35C1) can transport Guanosine diphosphate-fucose into the Golgi to facilitate protein glycosylation. Its mutation leads to the deficiency of leukocyte adhesion and enhances inflammation in humans. However, little is known about its role in liver diseases.Hepatic SLC35C1 mRNA transcripts and protein expression were significantly increased in patients with obstructive cholestasis and mouse models of cholestasis. Immunofluorescence revealed that the upregulated SLC35C1 expression mainly occurred in hepatocytes. Liver-specific ablation of Slc35c1 ( Slc35c1 cKO ) significantly aggravated liver injury in mouse models of cholestasis induced by bile duct ligation and 1% cholic acid-feeding, evidenced by increased liver necrosis, inflammation, fibrosis, and bile ductular proliferation. The Slc35c1 cKO increased hepatic chemokine Ccl2 and Cxcl2 expression and T cell, neutrophil, and F4/80 macrophage infiltration but did not affect the levels of serum and liver BA in mouse models of cholestasis. Liquid chromatography with tandem mass spectrometry analysis revealed that hepatic Slc35c1 deficiency substantially reduced the fucosylation of cell-cell adhesion protein CEACAM1 at N153. Mechanistically, cholestatic levels of conjugated BAs stimulated SLC35C1 expression by activating the STAT3 signaling to facilitate CEACAM1 fucosylation at N153, and deficiency in the fucosylation of CEACAM1 at N135 enhanced the BA-stimulated CCL2 and CXCL2 mRNA expression in primary mouse hepatocytes and Primary Liver Carcinoma/Poliomyelitis Research Foundation/5- ASBT cells.Elevated hepatic SLC35C1 expression attenuates cholestatic liver injury by enhancing CEACAM1 fucosylation to suppress CCL2 and CXCL2 expression and liver inflammation.Copyright © 2024 The Author(s).

1932-620318102023PloS onePLoS OneSpeech errors in consecutive interpreting: Effects of language proficiency, working memory, and anxiety.e0292718e0292718e029271810.1371/journal.pone.0292718Interpreting can be seen as a form of language production, where interpreters extract conceptual information from the source language and express it in the target language. Hence, like language production, interpreting contains speech errors at various (e.g., conceptual, syntactic, lexical and phonological) levels. The current study delved into the impact of language proficiency, working memory, and anxiety on the occurrence of speech errors across these linguistic strata during consecutive interpreting from English (a second language) into Chinese (a first language) by student interpreters. We showed that speech errors in general decreased as a function of the interpreter's proficiency in the source (second) language and increased as a function of the interpreter's anxiety. Conceptual errors, which result from mistaken comprehension of the source language, decreased as a function of language proficiency and working memory. Lexical errors increased as a function of the interpreter's tendency of anxiety. Syntactic errors also decreased as a function of language proficiency and increased as a function of anxiety. Phonological errors were not sensitive to any of the three cognitive traits. We discussed implications for the cognitive processes underlying interpreting and for interpreting training.Copyright: © 2023 Zhao et al.

The functional role of OATP1B3 in humans has not been characterized, as SLCO1B3 is poorly conserved among species without mouse orthologs.Slc10a1-knockout (Slc10a1-/-), Slc10a1hSLCO1B3 (endogenous mouse Slc10a1 promoter-driven human-SLCO1B3 expression in Slc10a1-/- mice), and human SLCO1B3 liver-specific transgenic (hSLCO1B3-LTG) mice were generated and challenged with 0.1% ursodeoxycholic-acid (UDCA), 1% cholic-acid (CA) diet, or bile duct ligation (BDL) for functional studies. Primary hepatocytes and hepatoma-PLC/RPF/5 cells were used for mechanistic studies.Serum BA levels in Slc10a1-/- mice were substantially increased with or without 0.1% UDCA feeding compared with wild-type (WT) mice. This increase was attenuated in Slc10a1hSLCO1B3-mice, indicating that OATP1B3 functions as a significant hepatic BA uptake transporter. In vitro assay using primary hepatocytes from WT, Slc10a1-/-, and Slc10a1hSLCO1B3-mice indicated that OATP1B3 has a similar capacity in taking up taurocholate/TCA as Ntcp. Furthermore, TCA-induced bile flow was significantly impaired in Slc10a1-/- mice but partially recovered in Slc10a1hSLC01B3-mice, indicating that OATP1B3 can partially compensate the NTCP function in vivo. Liver-specific overexpression of OATP1B3 markedly increased the level of hepatic conjugated BA and cholestatic liver injury in 1% CA-fed and BDL mice. Mechanistic studies revealed that conjugated BAs stimulated Ccl2 and Cxcl2 in hepatocytes to increase hepatic neutrophil infiltration and proinflammatory cytokine production (eg, IL-6), which activated STAT3 to repress OATP1B3 expression by binding to its promoter.Human OATP1B3 is a significant BA uptake transporter and can partially compensate Ntcp for conjugated BA uptake in mice. Its downregulation in cholestasis is an adaptive protective response.Copyright © 2023 The Authors. Published by Elsevier Inc.

In the present study, the effects of capsaicin and fermentation time on the microbial community and flavor compounds of chili paste were investigated. After capsaicin supplementation, the total acid was significantly decreased (p < 0.05) along with lower total bacteria, especially lactic acid bacteria. Lactiplantibacillus, Lactobacillus, Weissella, Issatchenkia, Trichoderma, and Pichia were the shared and predominant genera; whereas, the Bacteroides and Kazachstania abundance was significantly increased due to the selection effect of capsaicin over time. Additionally, alterations of the microbial interaction networks and their metabolic preferences led to less lactic acid content with greater accumulation of ethyl nonanoate, methyl nonanoate, etc. This study will provide a perspective for selecting chili pepper varieties and improving the quality of fermented chili paste.Copyright © 2023 Elsevier Ltd.

In cholestasis, bile secretion is impaired, leading to liver injury. However, it remains to be elucidated whether gut microbiota plays a role in cholestatic liver injury. Here, we performed a sham operation and bile duct ligation (BDL) in antibiotic-induced microbiome depleted (AIMD) mice and assessed liver injury and fecal microbiota composition in these mice. Significant reductions in gut microbiota richness and diversity were found in AIMD-sham mice when compared to sham controls. Three-day BDL leads to great elevation of plasma ALT, ALP, total bile acids, and bilirubin where reduced diversity of the gut microbiota was also found. AIMD further aggravated cholestatic liver injury evidenced by significantly higher levels of plasma ALT and ALP, associated with further reduced diversity and increased Gram-negative bacteria in gut microbiota. Further analyses revealed increased levels of LPS in the plasma of AIMD-BDL mice where elevated expression of inflammatory genes and decreased expression of hepatic detoxification enzymes were also found in liver when compared to the BDL group. These findings indicate that gut microbiota plays a critical role in cholestatic liver injury. Maintaining its homeostasis may alleviate liver injury in patients with cholestasis.ZhouXueqianXCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing 400038, China.ZhangXiaoxunX0000-0002-3892-7464Cholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing 400038, China.ZhaoNanNCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing 400038, China.ZhangLiangjunLCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing 400038, China.QiuWenWCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing 400038, China.SongChunweiCCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing 400038, China.ChaiJinJCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing 400038, China.CaiShiyingSThe Liver Center, Yale University School of Medicine, 333 Cedar Street, New Haven, CT 06520, USA.ChenWenshengWCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing 400038, China.eng82070599National Natural Science Foundation of ChinaJournal Article20230206

2041-17231412023Feb09Nature communicationsNat CommunUnique DUOX2+ACE2+ small cholangiocytes are pathogenic targets for primary biliary cholangitis.29292910.1038/s41467-022-34606-wCholangiocytes play a crucial role in bile formation. Cholangiocyte injury causes cholestasis, including primary biliary cholangitis (PBC). However, the etiology of PBC remains unclear despite being characterized as an autoimmune disease. Using single-cell RNA sequencing (scRNA-seq), fluorescence-activated-cell-sorting, multiplex immunofluorescence (IF) and RNAscope analyses, we identified unique DUOX2+ACE2+ small cholangiocytes in human and mouse livers. Their selective decrease in PBC patients was associated with the severity of disease. Moreover, proteomics, scRNA-seq, and qPCR analyses indicated that polymeric immunoglobulin receptor (pIgR) was highly expressed in DUOX2+ACE2+ cholangiocytes. Serum anti-pIgR autoantibody levels were significantly increased in PBC patients, regardless of positive and negative AMA-M2. Spatial transcriptomics and multiplex IF revealed that CD27+ memory B and plasma cells accumulated in the hepatic portal tracts of PBC patients. Collectively, DUOX2+ACE2+ small cholangiocytes are pathogenic targets in PBC, and preservation of DUOX2+ACE2+ cholangiocytes and targeting anti-pIgR autoantibodies may be valuable strategies for therapeutic interventions in PBC.© 2023.

2058-7716912023Jan23Cell death discoveryCell Death DiscovHepatic TNFRSF12A promotes bile acid-induced hepatocyte pyroptosis through NFκB/Caspase-1/GSDMD signaling in cholestasis.26262610.1038/s41420-023-01326-zTumor necrosis factor receptor superfamily member-12A (TNFRSF12A) plays a critical role in inflammation and cell death. It is expressed in multiple tissues yet extremely low in normal liver. To date, little is known about its role in cholestasis. Therefore, we sought to delineate the role of TNFRSF12A in cholestasis and its underlying mechanisms. Human liver tissues were collected from patients with obstructive cholestasis (OC) or primary biliary cholangitis (PBC). Tnfrsf12a knockout (KO) mice were generated. Cholestasis was induced by bile-duct ligation (BDL) or 0.1% 5-diethoxycarbonyl-1,4-dihydrocollidine (DDC)-feeding. Human hepatoma PLC/PRF/5-ASBT and THP1 cell lines or primary mouse hepatocytes were used for mechanistic studies. Hepatic TNFRSF12A expression was markedly increased in OC or PBC patients. Genetic ablation of Tnfrsf12a in BDL- and 0.1%DDC-induced cholestatic mice significantly attenuated cholestatic liver injury with remarkable reduction of hepatocyte pyroptosis but without changing scores of necroptosis and apoptosis. Morphological features of hepatocyte pyroptosis and increased levels of pyroptosis-related proteins, NLRP3, cleaved-Caspase-1, and cleaved-GSDMD in OC patients and BDL-mice confirmed this observation. Further mechanistic studies revealed that bile acids (BAs) induced TNFRSF12A expression by enhancing the transcription factor c-JUN binding to the TNFRSF12A promoter and subsequently initiated hepatocyte pyroptosis by the NFκB/Caspase-1/GSDMD signaling. Interestingly, TWEAK, a typical ligand of TNFRSF12A, secreted by infiltrated macrophages in cholestatic livers, enhanced TNFRSF12A-induced hepatocyte pyroptosis. Taken together, we report, for the first time, that hepatic TNFRSF12A is dramatically increased in human cholestasis. Deletion of TNFRSF12A inhibits BAs-induced hepatocyte pyroptosis through the NFκB/Caspase-1/GSDMD signaling and thereby ameliorates cholestatic liver injury. As such, targeting TNFRSF12A could be a promising approach to treating cholestasis.© 2023.

1527-33507762023Jun01Hepatology (Baltimore, Md.)HepatologyRunt-related transcription factor-1 ameliorates bile acid-induced hepatic inflammation in cholestasis through JAK/STAT3 signaling.186618811866-188110.1097/HEP.0000000000000041Bile acids trigger a hepatic inflammatory response, causing cholestatic liver injury. Runt-related transcription factor-1 (RUNX1), primarily known as a master modulator in hematopoiesis, plays a pivotal role in mediating inflammatory responses. However, RUNX1 in hepatocytes is poorly characterized, and its role in cholestasis is unclear. Herein, we aimed to investigate the role of hepatic RUNX1 and its underlying mechanisms in cholestasis.Hepatic expression of RUNX1 was examined in cholestatic patients and mouse models. Mice with liver-specific ablation of Runx1 were generated. Bile duct ligation and 1% cholic acid diet were used to induce cholestasis in mice. Primary mouse hepatocytes and the human hepatoma PLC/RPF/5- ASBT cell line were used for mechanistic studies. Hepatic RUNX1 mRNA and protein levels were markedly increased in cholestatic patients and mice. Liver-specific deletion of Runx1 aggravated inflammation and liver injury in cholestatic mice induced by bile duct ligation or 1% cholic acid feeding. Mechanistic studies indicated that elevated bile acids stimulated RUNX1 expression by activating the RUNX1 -P2 promoter through JAK/STAT3 signaling. Increased RUNX1 is directly bound to the promotor region of inflammatory chemokines, including CCL2 and CXCL2 , and transcriptionally repressed their expression in hepatocytes, leading to attenuation of liver inflammatory response. Blocking the JAK signaling or STAT3 phosphorylation completely abolished RUNX1 repression of bile acid-induced CCL2 and CXCL2 in hepatocytes.This study has gained initial evidence establishing the functional role of hepatocyte RUNX1 in alleviating liver inflammation during cholestasis through JAK/STAT3 signaling. Modulating hepatic RUNX1 activity could be a new therapeutic target for cholestasis.Copyright © 2023 American Association for the Study of Liver Diseases.ZhangLiangjunL0000-0002-7053-8661Department of

Experiment 1 showed that deaf writers of Mandarin Chinese exhibited comparable extents of structural priming and comparable lexical boosts, suggesting that syntactic encoding in written language production is similarly sensitive to prior lexical-syntactic experience in deaf and hearing writers. Experiment 2 showed that, while hearing writers showed a boost in structural priming when the prime and the target had homographic or heterographic homophone dative verbs compared to unrelated ones, deaf writers showed a homophone boost only with homographic homophone verbs but not with heterographic homophone verbs. This finding suggests that while hearing people develop associated lemmas for homophones due to phonological identity, deaf people do so due to orthographic identity. Finally, Experiment 3 showed no boost in structural priming in deaf writers or hearing writers when the prime and the target had the same verb of the same orthography (i.e., in the same script) than of different orthographies (i.e., between Simplified and Traditional Chinese), suggesting that neither hearing nor deaf people use orthographic identity to reactivate the prime structure. In all, the findings suggest that syntactic encoding in writing employs the same syntactic and lexical representations in deaf and hearing writers, though lexical representations are shaped more by orthography than phonology in deaf writers.

1744-790964122022DecJournal of integrative plant biologyJ Integr Plant BiolArabidopsis Trithorax histone methyltransferases are redundant in regulating development and DNA methylation.243824542438-245410.1111/jipb.13406Although the Trithorax histone methyltransferases ATX1-5 are known to regulate development and stress responses by catalyzing histone H3K4 methylation in Arabidopsis thaliana, it is unknown whether and how these histone methyltransferases affect DNA methylation. Here, we found that the redundant ATX1-5 proteins are not only required for plant development and viability but also for the regulation of DNA methylation. The expression and H3K4me3 levels of both RNA-directed DNA methylation (RdDM) genes (NRPE1, DCL3, IDN2, and IDP2) and active DNA demethylation genes (ROS1, DML2, and DML3) were downregulated in the atx1/2/4/5 mutant. Consistent with the facts that the active DNA demethylation pathway mediates DNA demethylation mainly at CG and CHG sites, and that the RdDM pathway mediates DNA methylation mainly at CHH sites, whole-genome DNA methylation analyses showed that hyper-CG and CHG DMRs in atx1/2/4/5 significantly overlapped with those in the DNA demethylation pathway mutant ros1 dml2 dml3 (rdd), and that hypo-CHH DMRs in atx1/2/4/5 significantly overlapped with those in the RdDM mutant nrpe1, suggesting that the ATX paralogues function redundantly to regulate DNA methylation by promoting H3K4me3 levels and expression levels of both RdDM genes and active DNA demethylation genes. Given that the ATX proteins function as catalytic subunits of COMPASS histone methyltransferase complexes, we also demonstrated that the COMPASS complex components function as a whole to regulate DNA methylation. This study reveals a previously uncharacterized mechanism underlying the regulation of DNA methylation.© 2022 Institute of Botany, Chinese Academy of Sciences.ShangJi-YunJY0000-0003-1004-0818National Institute of Biological Sciences, Beijing, 102206, China.CaiXue-WeiXWNational Institute of Biological Sciences, Beijing, 102206, China.SuYin-NaYN0000-0002-7319-5086National Institute of Biological Sciences, Beijing, 102206, China.ZhangZhao-ChenZC0000-0002-0769-0388National Institute of Biological Sciences, Beijing, 102206, China.WangXinXNational Institute of Biological Sciences, Beijing, 102206, China.ZhaoNanN0000-0001-7147-9002National Institute of Biological Sciences, Beijing, 102206, China.HeXin-JianXJ0000-0002-2878-7461National Institute of Biological Sciences, Beijing, 102206, China.Tsinghua Institute of Multidisciplinary Biomedical Research, Tsinghua University, Beijing, 100084, China.engJournal Article20221205

Semaphorin7a (Sema7a) deficiency in mouse peritoneal macrophages reduces fatty acid (FA) oxidation. Here, we identified 17 individuals with SEMA7A heterozygous mutations in 470 patients with biopsy-proven NAFLD. SEMA7A heterozygous mutations increased susceptibility to NAFLD, steatosis severity, and NAFLD activity scores in humans and mice. The Sema7aR145W mutation (equivalent to human SEMA7AR148W) significantly induced small lipid droplet accumulation in mouse livers compared with WT mouse livers. Mechanistically, the Sema7aR145W mutation increased N-glycosylated Sema7a and its receptor integrin β1 proteins in the cell membranes of hepatocytes. Furthermore, Sema7aR145W mutation enhanced its protein interaction with integrin β1 and PKC-α and increased PKC-α phosphorylation, which were both abrogated by integrin β1 silencing. Induction of PKCα_WT, but not PKCα_dominant negative, overexpression induced transcriptional factors Srebp1, Chrebp, and Lxr expression and their downstream Acc1, Fasn, and Cd36 expression in primary mouse hepatocytes. Collectively, our findings demonstrate that the SEMA7AR148W mutation is a potentially new strong genetic determinant of NAFLD and promotes intrahepatic lipid accumulation and NAFLD in mice by enhancing PKC-α-stimulated FA and triglyceride synthesis and FA uptake. The inhibition of hepatic PKC-α signaling may lead to novel NAFLD therapies.ZhaoNanNDepartment of Gastroenterology, Institute of Digestive Diseases of PLA, Cholestatic Liver Diseases Center, and

1755-594928102022OctCNS neuroscience & therapeuticsCNS Neurosci TherTelitacicept following plasma exchange in the treatment of subjects with recurrent neuromyelitis optica spectrum disorders: A single-center, single-arm, open-label study.161316231613-162310.1111/cns.13904Neuromyelitis optica spectrum disorders (NMOSD), mainly mediated by B cells and AQP4 antibody, has a high rate of recurrence. Telitacicept is a novel drug specifically targeting the upstream signaling for the activation of B cell with its following production of autoimmune antibodies. Thus, it may be a promising approach. Our study preliminarily explored the potential safety and effectiveness of Telitacicept following plasma exchange in the treatment of recurrent NMOSD.This was a single-center, single-arm, open-label study enrolling eight patients with recurrent NMOSD in China. All patients received plasma exchange three times, followed by Telitacicept 240 mg every week for 46 times. The primary endpoint was the time of first recurrence after enrollment. Secondary end points included: changes in Expanded Disability Status Scale score, Optic Spinal Impairment Scale score, Hauser Ambulation Index, number of lesions on MRI, retinal nerve fiber layer thickness measured by optical coherence tomography, latency and amplitude of visual evoked potential, titer of AQP4 antibody, and immune parameters of blood. Safety was also assessed. The study was registered with Chictr.org.cn (ChiCTR1800019427).Eight eligible patients were enrolled. Relapse occurred in two patients (25%) and five patients (63%) remained relapse free after 48 weeks of treatment. The time to first recurrence was prolonged and the number of recurrences was reduced (p < 0.001, power of test = 1). One patient withdrew from the study due to low neutrophil count. No serious adverse events occurred.In this small, uncontrolled study, Telitacicept following plasma exchange has the potential to be a safe treatment for patients with recurrent NMOSD. It may prolong the recurrence interval and reduces the annual count of recurrences. A multicenter randomized controlled study with a larger sample is thus feasible and needed to further assess its safety and efficacy.© 2022 The Authors.

1664-2295132022Frontiers in neurologyFront NeurolHuman Umbilical Cord Mesenchymal Stem Cells to Treat Neuromyelitis Optica Spectrum Disorder (hUC-MSC-NMOSD): A Study Protocol for a Prospective, Multicenter, Randomized, Placebo-Controlled Clinical Trial.86008386008386008310.3389/fneur.2022.860083Neuromyelitis Optica spectrum disorder (NMOSD) is severe relapsing and disabling autoimmune disease of the central nervous system. Its optimal first-line treatment to reduce relapse rate and ameliorate neurological disability remains unclear. We will conduct a prospective, multicenter, randomized, placebo-controlled clinical trial to study the safety and effectiveness of human umbilical cord mesenchymal stem cells (hUC-MSCs) in treating NMOSD.The trial is planned to recruit 430 AQP4-IgG seropositive NMOSD patients. It consists of three consecutive stages. The first stage will be carried out in the leading center only and aims to evaluate the safety of hUC-MSCs. Patients will be treated with three different doses of hUC-MSCs: 1, 2, or 5 × 106 MSC/kg·weight for the low-, medium-, and high-dose group, respectively. The second and third stages will be carried out in six centers. The second stage aims to find the optimal dosage. Patients will be 1:1:1:1 randomized into the low-, medium-, high-dose group and the controlled group. The third stage aims to evaluate the effectiveness. Patients will be 1:1 randomized into the optimal dose and the controlled group. The primary endpoint is the first recurrent time and secondary endpoints are the recurrent times, EDSS scores, MRI lesion numbers, OSIS scores, Hauser walking index, and SF-36 scores. Endpoint events and side effects will be evaluated every 3 months for 2 years.Although hUC-MSC has shown promising treatment effects of NMOSD in preclinical studies, there is still a lack of well-designed clinical trials to evaluate the safety and effectiveness of hUC-MSC among NMOSD patients. As far as we know, this trial will be the first one to systematically demonstrate the clinical safety and efficacy of hUC-MSC in treating NMOSD and might be able to determine the optimal dose of hUC-MSC for NMOSD patients.The study was registered with the Chinese Clinical Trial Registry (CHICTR.org.cn) on 2 March 2016 (registration No. ChiCTR-INR-16008037), and the revised trial protocol (Protocol version 1.2.1) was released on 16 March 2020.Copyright © 2022 Yao, Xie, Cai, Zhang, Deng, Gao, Wang, Xu, Ding, Wu, Zhao, Wang, Song, Wang, Xie, Li, Wan, Lin, Jin, Wang, Qiu, Zhuang, Zhou, Jin, Ni, Yan, Guo, Xue, Qian and Guan.YaoXiao-YingXYDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.XieLiLClinical Research Center, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.CaiYuYDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.ZhangYingYDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.DengYeYDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.GaoMei-ChunMCDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.WangYi-ShuYSDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.XuHui-MingHMState Key Laboratory of Oncogenes and Related Genes, Renji-Med-X Clinical Stem Cell Research Center, Renji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.DingJieJDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.WuYi-FanYFDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.ZhaoNanNDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.WangZeZDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.SongYa-YingYYDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.WangLi-PingLPDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.XieChongCDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.LiZe-ZhiZZDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.WanWen-BinWBDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.LinYanYDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.JinHai-FengHFDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.WangKanKDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.QiuHui-YingHYDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.ZhuangLeiLDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.ZhouYanYDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.JinYu-YanYYDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.NiLi-PingLPDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.YanJia-LiJLDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.GuoQuanQDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.XueJia-HuiJHDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.QianBi-YunBYClinical Research Center, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.Shanghai Clinical Research Promotion and Development Center, Shanghai Hospital Development Center, Shanghai, China.GuanYang-TaiYTDepartment of Neurology, Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.engJournal Article20220425

1527-33507712023Jan01Hepatology (Baltimore, Md.)HepatologyIntestinal peroxisome proliferator-activated receptor α-fatty acid-binding protein 1 axis modulates nonalcoholic steatohepatitis.239255239-25510.1002/hep.32538Peroxisome proliferator-activated receptor α (PPARα) regulates fatty acid transport and catabolism in liver. However, the role of intestinal PPARα in lipid homeostasis is largely unknown. Here, intestinal PPARα was examined for its modulation of obesity and NASH.Intestinal PPARα was activated and fatty acid-binding protein 1 (FABP1) up-regulated in humans with obesity and high-fat diet (HFD)-fed mice as revealed by using human intestine specimens or HFD/high-fat, high-cholesterol, and high-fructose diet (HFCFD)-fed C57BL/6N mice and PPARA -humanized, peroxisome proliferator response element-luciferase mice. Intestine-specific Ppara or Fabp1 disruption in mice fed a HFD or HFCFD decreased obesity-associated metabolic disorders and NASH. Molecular analyses by luciferase reporter assays and chromatin immunoprecipitation assays in combination with fatty acid uptake assays in primary intestinal organoids revealed that intestinal PPARα induced the expression of FABP1 that in turn mediated the effects of intestinal PPARα in modulating fatty acid uptake. The PPARα antagonist GW6471 improved obesity and NASH, dependent on intestinal PPARα or FABP1. Double-knockout ( Ppara/Fabp1ΔIE ) mice demonstrated that intestinal Ppara disruption failed to further decrease obesity and NASH in the absence of intestinal FABP1. Translationally, GW6471 reduced human PPARA-driven intestinal fatty acid uptake and improved obesity-related metabolic dysfunctions in PPARA -humanized, but not Ppara -null, mice.Intestinal PPARα signaling promotes NASH progression through regulating dietary fatty acid uptake through modulation of FABP1, which provides a compelling therapeutic target for NASH treatment.Copyright © 2022 The Author(s).

But how do they do so? We contrasted a nonliteral syntactic analysis account, according to which people compute a syntactic analysis appropriate for this nonliteral meaning, with a nonliteral semantic interpretation account, according to which they arrive at this meaning via purely semantic processing. The former but not the latter account postulates that people consider not only a literal-but-implausible double-object (DO) analysis in comprehending The mother gave the candle the daughter, but also a nonliteral-but-plausible prepositional-object (PO) analysis (i.e., including to before the daughter). In three structural priming experiments, participants heard a plausible or implausible DO or PO prime sentence. They then answered a comprehension question first or described a picture of a dative event first. In accord with the nonliteral syntactic analysis account, priming was reduced following implausible sentences than following plausible sentences and following nonliterally interpreted implausible sentences than literally interpreted implausible sentences. The results suggest that comprehenders constructed a nonliteral syntactic analysis, which we argue was predicted early in the sentence.Copyright © 2022.

1469-813723322022JanThe New phytologistNew PhytolThe RNA recognition motif-containing protein UBA2c prevents early flowering by promoting transcription of the flowering repressor FLM in Arabidopsis.751765751-76510.1111/nph.17836FLOWERING LOCUS M (FLM) is a well-known MADS-box transcription factor that is required for preventing early flowering under low temperatures in Arabidopsis thaliana. Alternative splicing of FLM is involved in the regulation of temperature-responsive flowering. However, how the basic transcript level of FLM is regulated is largely unknown. Here, we conducted forward genetic screening and identified a previously uncharacterized flowering repressor gene, UBA2c. Genetic analyses indicated that UBA2c represses flowering at least by promoting FLM transcription. We further demonstrated that UBA2c directly binds to FLM chromatin and facilitates FLM transcription by inhibiting histone H3K27 trimethylation, a histone marker related to transcriptional repression. UBA2c encodes a protein containing two putative RNA recognition motifs (RRMs) and one prion-like domain (PrLD). We found that UBA2c forms speckles in the nucleus and that both the RRMs and PrLD are required not only for forming the nuclear speckles but also for the biological function of UBA2c. These results identify a previously unknown flowering repressor and provide insights into the regulation of flowering time.© 2021 The Authors.

1757-468413112021Nov08EMBO molecular medicineEMBO Mol MedA homozygous R148W mutation in Semaphorin 7A causes progressive familial intrahepatic cholestasis.e14563e14563e1456310.15252/emmm.202114563Semaphorin 7A (SEMA7A) is a membrane-bound protein that involves axon growth and other biological processes. SEMA7A mutations are associated with vertebral fracture and Kallmann syndrome. Here, we report a case with a mutation in SEMA7A that displays familial cholestasis. WGS reveals a SEMA7AR148W homozygous mutation in a female child with elevated levels of serum ALT, AST, and total bile acid (TBA) of unknown etiology. This patient also carried a SLC10A1S267F allele, but Slc10a1S267F homozygous mice exhibited normal liver function. Similar to the child, Sema7aR145W homozygous mice displayed elevated levels of serum ALT, AST, and TBA. Remarkably, liver histology and LC-MS/MS analyses exhibited hepatocyte hydropic degeneration and increased liver bile acid (BA) levels in Sema7aR145W homozygous mice. Further mechanistic studies demonstrated that Sema7aR145W mutation reduced the expression of canalicular membrane BA transporters, bile salt export pump (Bsep), and multidrug resistance-associated protein-2 (Mrp2), causing intrahepatic cholestasis in mice. Administration with ursodeoxycholic acid and a dietary supplement glutathione improved liver function in the child. Therefore, Sema7aR145W homozygous mutation causes intrahepatic cholestasis by reducing hepatic Bsep and Mrp2 expression.© 2021 The Authors Published under the terms of the CC BY 4.0 license.PanQiongQ0000-0003-1033-3098Cholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.LuoGangGCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.QuJiaquanJ0000-0002-0204-5646Cholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.ChenShengSDepartment of Pediatrics, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.ZhangXiaoxunX0000-0002-3892-7464Cholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.ZhaoNanNCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.DingJingjingJCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.YangHongHCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.LiMingqiaoMCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.LiLingLCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.ChengYingYCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.LiXuanXCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.XieQiaolingQCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.LiQiaoQCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.ZhouXueqianXCholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.ZouHuilingHDepartment of Pediatrics, Changsha Hospital for Maternal & Child Health Care, Changsha, China.FanShijunSMedical Research Center, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.ZouLingyunLBao'an Maternal and Child Health Hospital, Jinan University, Shenzhen, China.LiuWeiWInstitute of Immunology, Third Military Medical University (Army Medical University), Chongqing, China.DengGuohongGDepartment of Infectious Diseases, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.CaiShi-YingSYDepartment of Internal Medicine and Liver Center, Yale University School of Medicine, New Haven, CT, USA.BoyerJames LJL0000-0002-8959-6036Department of Internal Medicine and Liver Center, Yale University School of Medicine, New Haven, CT, USA.ChaiJinJ0000-0002-8543-4566Cholestatic Liver Diseases Center, Department of Gastroenterology, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing, China.engJournal ArticleResearch Support, Non-U.S. Gov't20210929

However, the epidemiological features of fractures in mainland China are not well known.To assess the prevalence of and factors associated with osteoporosis, clinical fractures, and vertebral fractures in an adult population 40 years or older in mainland China.This cross-sectional study, the China Osteoporosis Prevalence Study, was conducted from December 2017 to August 2018. A random sample of individuals aged 20 years or older who represented urban and rural areas of China were enrolled, with a 99% participation rate.Weighted prevalence of osteoporosis, clinical fracture, and vertebral fracture by age, sex, and urban vs rural residence as determined by x-ray absorptiometry, questionnaire, and radiography.A total of 20 416 participants were included in this study; 20 164 (98.8%; 11 443 women [56.7%]; mean [SD] age, 53 [13] years) had a qualified x-ray absorptiometry image and completed the questionnaire, and 8423 of 8800 (95.7%) had a qualified spine radiograph. The prevalence of osteoporosis among those aged 40 years or older was 5.0% (95% CI, 4.2%-5.8%) among men and 20.6% (95% CI, 19.3%-22.0%) among women. The prevalence of vertebral fracture was 10.5% (95% CI, 9.0%-12.0%) among men and 9.7% (95% CI, 8.2%-11.1%) among women. The prevalence of clinical fracture in the past 5 years was 4.1% (95% CI, 3.3%-4.9%) among men and 4.2% (95% CI, 3.6%-4.7%) among women. Among men and women, 0.3% (95% CI, 0.0%-0.7%) and 1.4% (95% CI, 0.8%-2.0%), respectively, with osteoporosis diagnosed on the basis of bone mineral density or with fracture were receiving antiosteoporosis treatment to prevent fracture.In this cross-sectional study of an adult population in mainland China, the prevalence of osteoporosis and vertebral fracture were high and the prevalence of vertebral fracture and clinical fracture was similarly high in men and women. These findings suggest that current guidelines for screening and treatment of fractures among patients in China should focus equally on men and women and should emphasize the prevention of vertebral fractures.WangLinhongLNational Center for Chronic and Non-communicable Disease Control and Prevention, Chinese Center for Disease Control and Prevention, Beijing, China.YuWeiWDepartment of Radiology,

1554-35285412022FebBehavior research methodsBehav Res MethodsObjective ages of acquisition for 3300+ simplified Chinese characters.311323311-32310.3758/s13428-021-01626-1We report the construction of two age-of-acquisition (AoA) norms for 3300+ characters in simplified Chinese, which make up about 99% of the texts used in daily life. We determined a character's AoA according to the time in which the character is formally learned in two sets of leading textbooks of Chinese in compulsory education, published respectively on the basis of the 2001 and 2011 national curriculum. Apart from having a significantly larger coverage of characters than previous norms, the current norms also outperformed them in explaining accuracy and reaction times in four large-scale databases for character decision, character naming, or character handwriting, even after controlling for the effects of frequency, number of meanings, and number of strokes. The explanatory advantage of the current norms suggests that, compared to earlier norms, the current norms capture more up-to-date character AoAs; these findings also highlight the diachronic nature of some lexical variables such as AoA and frequency. The developed objective AoA norms can be used for subsequent research on Chinese character recognition or production.© 2021.

The available choices for disease prevention are few or intolerable. Previous studies suggested that telitacicept may provide a promising therapeutic strategy for autoimmune diseases involving B cells. Therefore, this study aims to assess the effectiveness and safety of telitacicept for recurrent NMOSD. Methods: We will perform a single-arm, single-center, open-label, specialist study with a total enrollment of eight participants. The treatment regimen includes plasma exchange three times and subcutaneous injection of telitacicept for 46 cycles, with a total period of 48 weeks. The primary endpoint is the time to first recurrence after enrollment. Secondary endpoints are Expanded Disability Status Scale (EDSS) score, Opticospinal Impairment Scale (OSIS) score, Hauser Ambulation Index, number of lesions on MRI, and changes in visual evoked potential (VEP), optical coherence tomography (OCT) and immunologic status. All adverse events after medication will be documented and investigated. Discussion: This study will explore the safety and effectiveness of telitacicept following plasma exchange regarding the time to recurrence in neuromyelitis optica spectrum disorder (NMOSD) for the first time.

1664-2295122021Frontiers in neurologyFront NeurolAssociation Between Low-Density Lipoprotein Cholesterol and Platelet Distribution Width in Acute Ischemic Stroke.63122763122763122710.3389/fneur.2021.631227Objective: Elevated low-density lipoprotein cholesterol (LDL-C) is an established risk factor for ischemic stroke; however, whether LDL-C affects the platelet deformation function in the peripheral blood circulation in patients with acute ischemic stroke (AIS) is unknown. The present study aimed to investigate the relationship between LDL-C and platelet distribution width (PDW) in AIS patients. Methods: We conducted a cross-sectional hospitalized-based study of consecutive 438 patients with AIS within 24 h. Blood samples were collected upon admission and prior to drug administration, and LDL-C and PDW (a parameter that reflects the heterogeneity of platelet volume) were assessed. The relationship between LDL-C and PDW were analyzed by linear curve fitting analyses. Crude and adjusted beta coefficients of LDL-C for PDW with 95% confidence intervals were analyzed using multivariate-adjusted linear regression models. Results: The PDW was significantly higher in the high LDL-C group compared with those in the normal LDL-C group (16.28 ± 0.37 fl vs. 16.08 ± 0.37 fl, p < 0.001). Adjusted smoothed plots suggested that there are linear relationships between LDL-C and PDW, and the Pearson's correlation coefficient (95%) was 0.387 (0.304-0.464, p < 0.001). The beta coefficients (95% CI) between LDL-C and PDW were 0.15 (0.12-0.18, p < 0.001) and 0.14 (0.11-0.18, p < 0.001), respectively, in AIS patients before and after adjusting for potential confounders. Conclusion: Our study suggested that the elevated LDL-C level was related to increased PDW among AIS patients.Copyright © 2021 Yuan, Cai, Zhao, Zhao, Hong, Ding, Yang, Fan, Zhu, Zhou, Li, Zhu and Guan.YuanJianJDepartment of Neurology, Baoshan Branch, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.CaiJianJDepartment of Neurology, Baoshan Branch, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.Department of Neurology, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.ZhaoPeiPDepartment of Neurology, Baoshan Branch, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.ZhaoNanNDepartment of Neurology, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.HongRong-HuaRHDepartment of Neurology, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.DingJieJDepartment of Neurology, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.YangJinJDepartment of Neurology, Baoshan Branch, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.FanQing-LeiQLDepartment of Neurology, Baoshan Branch, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.ZhuJianJDepartment of Neurology, Baoshan Branch, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.ZhouXia-JunXJDepartment of Neurology, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.LiZe-ZhiZZDepartment of Neurology, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.ZhuDe-ShengDSDepartment of Neurology, Baoshan Branch, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.Department of Neurology, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.GuanYang-TaiYTDepartment of Neurology, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.engJournal Article20210305

However, the mechanism by which magnetic protein enables a biocompass is still under debate, mainly because of the absence of permanent magnetism in the magnetic protein at room temperature. Here, based on a widely accepted radical pair model of a biocompass, we propose a microscopic mechanism that allows the biocompass to operate without a finite magnetization of the magnetic protein in a biological environment. With the structure of the magnetic protein, we show that the magnetic fluctuation, rather than the permanent magnetism, of the magnetic protein can enable geomagnetic field sensing. An analysis of the quantum dynamics of our microscopic model reveals the necessary conditions for optimal sensitivity.

Methods A549 cells were treated with 0, 1, 2, 3, 4, 5, 6 μmol/L celastrol for 0, 24, 48, 72 hours. The effects of different concentrations and durations on the cell proliferation were evaluated by MTT assay to determine the optimal concentration and treatment time. In the subsequent experiments, A549 cells were treated with (0, 1, 3) μmol/L of celastrol for 48 hours. The effects of celastrol on the expression of BAX, B-cell lymphoma 2 (Bcl2), caspase-3, caspase-8, caspase-9 mRNA in A549 cells were detected by real-time quantitative PCR. The protein levels of BAX, Bcl-2, cleaved caspase-3(c-caspase-3), c-caspase-8, c-caspase-9 were assessed by Western blot analysis. Results Celastrol inhibited the viability of A549 cells in a concentration- and time-dependent manner. Compared with the group without celastrol treatment, the mRNA and protein level of Bcl2 in A549 cells treated with (1, 3) μmol/L celastrol decreased significantly, while the expression levels of BAX, caspase-3, caspase-8, caspase-9, c-caspase-3, c-caspase-8, c-caspase-9 increased significantly. Conclusion Celastrol could suppress the proliferation and induced the apoptosis of A549 cells through mitochondrial pathway.ZhaoNanNInstitute of Translational Medicine, First Affiliated Hospital, Jinzhou Medical University, Jinzhou 121000, China.WangHongHInstitute of Translational Medicine, First Affiliated Hospital, Jinzhou Medical University, Jinzhou 121000, China.MuChunqingCInstitute of Translational Medicine, First Affiliated Hospital, Jinzhou Medical University, Jinzhou 121000, China.WangQiuningQDepartment of Pharmacology, Jinzhou Medical University, Jinzhou 121000, China.CaiZhiyangZDepartment of Medicine Management, First Affiliated Hospital, Jinzhou Medical University, Jinzhou 121000, China. *Corresponding author, E-mail: Zhiycai2015@outlook.com.chiJournal Article

Background And Aims: Inflammatory response is crucial for bile acid (BA)-induced cholestatic liver injury, but molecular mechanisms remain to be elucidated. Solute Carrier Family 35 Member C1 (SLC35C1) can transport Guanosine diphosphate-fucose into the Golgi to facilitate protein glycosylation. Its mutation leads to the deficiency of leukocyte adhesion and enhances inflammation in humans.

Background & Aims: OATP1B3/SLCO1B3 is a human liver-specific transporter for the clearance of endogenous compounds (eg, bile acid [BA]) and xenobiotics. The functional role of OATP1B3 in humans has not been characterized, as SLCO1B3 is poorly conserved among species without mouse orthologs.

Methods: Slc10a1-knockout (Slc10a1), Slc10a1 (endogenous mouse Slc10a1 promoter-driven human-SLCO1B3 expression in Slc10a1 mice), and human SLCO1B3 liver-specific transgenic (hSLCO1B3-LTG) mice were generated and challenged with 0.

In three structural priming experiments, we investigated whether deaf and hearing writers differ in the processes and representations underlying written language production. Experiment 1 showed that deaf writers of Mandarin Chinese exhibited comparable extents of structural priming and comparable lexical boosts, suggesting that syntactic encoding in written language production is similarly sensitive to prior lexical-syntactic experience in deaf and hearing writers. Experiment 2 showed that, while hearing writers showed a boost in structural priming when the prime and the target had homographic or heterographic homophone dative verbs compared to unrelated ones, deaf writers showed a homophone boost only with homographic homophone verbs but not with heterographic homophone verbs.

Although the Trithorax histone methyltransferases ATX1-5 are known to regulate development and stress responses by catalyzing histone H3K4 methylation in Arabidopsis thaliana, it is unknown whether and how these histone methyltransferases affect DNA methylation. Here, we found that the redundant ATX1-5 proteins are not only required for plant development and viability but also for the regulation of DNA methylation. The expression and H3K4me3 levels of both RNA-directed DNA methylation (RdDM) genes (NRPE1, DCL3, IDN2, and IDP2) and active DNA demethylation genes (ROS1, DML2, and DML3) were downregulated in the atx1/2/4/5 mutant.

People sometimes interpret implausible sentences nonliterally, for example treating The mother gave the candle the daughter as meaning the daughter receiving the candle. But how do they do so? We contrasted a nonliteral syntactic analysis account, according to which people compute a syntactic analysis appropriate for this nonliteral meaning, with a nonliteral semantic interpretation account, according to which they arrive at this meaning via purely semantic processing. The former but not the latter account postulates that people consider not only a literal-but-implausible double-object (DO) analysis in comprehending The mother gave the candle the daughter, but also a nonliteral-but-plausible prepositional-object (PO) analysis (i.

We report the construction of two age-of-acquisition (AoA) norms for 3300+ characters in simplified Chinese, which make up about 99% of the texts used in daily life. We determined a character's AoA according to the time in which the character is formally learned in two sets of leading textbooks of Chinese in compulsory education, published respectively on the basis of the 2001 and 2011 national curriculum. Apart from having a significantly larger coverage of characters than previous norms, the current norms also outperformed them in explaining accuracy and reaction times in four large-scale databases for character decision, character naming, or character handwriting, even after controlling for the effects of frequency, number of meanings, and number of strokes.
