| 3 | Connexin 43 hemichannels protect bone loss during estrogen deficiency显示文摘Estrogen deficiency in postmenopausal women is a major cause of bone loss,resulting in osteopenia,osteoporosis,and a high risk for bone fracture.Connexin 43 (Cx43) hemichannels (HCs) in osteocytes play an important role in osteocyte viability,bone formation,and remodeling.We showed here that estrogen deficiency reduced Cx43 expression and HC function.To determine if functional HCs protect osteocytes and bone loss during estrogen deficiency,we adopted an ovariectomy model in wild-type (WT) and two transgenic Cx43 mice:R76W (dominant-negative mutant inhibiting only gap junction channels) and Cx43 Δ130–136 (dominant-negative mutant compromising both gap junction channels and HCs).The bone mineral density (BMD),bone structure,and histomorphometric changes of cortical and trabecular bones after ovariectomy were investigated.Our results showed that the Δ130–136 transgenic cohort had greatly decreased vertebral trabecular bone mass compared to WT and R76W mice,associated with a significant increase in the number of apoptotic osteocyte and empty lacunae.Moreover,osteoclast surfaces in trabecular and cortical bones were increased after ovariectomy in the R76W and WT mice,respectively,but not in Δ130–136 mice.These data demonstrate that impairment of Cx43 HCs in osteocytes accelerates vertebral trabecular bone loss and increase in osteocyte apoptosis,and further suggest that Cx43 HCs in osteocytes protect trabecular bone against catabolic effects due to estrogen deficiency. | Liang Ma Rui Hua Yi Tian Hongyun Cheng Roberto Jose Fajardo Joseph J.

| 4 | Schistosoma mansoni proteins attenuate gastrointestinal motility disturbances during experimental colitis in mice显示文摘AIM:To investigate the therapeutic effect of Schistosoma mansoni(S.mansoni) soluble worm proteins on gastrointestinal motility disturbances during experimental colitis in mice. METHODS:Colitis was induced by intrarectal injection of trinitrobenzene sulphate(TNBS) and 6 h later,mice were treated ip with S.mansoni proteins.Experiments were performed 5 d after TNBS injection.Inflammationwas quantified using validated inflammation parameters. Gastric emptying and geometric center were measured to assess in vivo gastrointestinal motility.Peristaltic activity of distal colonic segments was studied in vitro using a modified Trendelenburg set-up.Cytokine profiles of T-lymphocytes isolated from the colon were determined by real time reverse transcriptase-polymerase chain reaction. RESULTS:Intracolonic injection of TNBS caused severe colitis.Treatment with S.mansoni proteins significantly ameliorated colonic inflammation after 5 d.TNBS did not affect gastric emptying but significantly decreased the geometric center and impaired colonic peristaltic activity 5 d after the induction of colitis.Treatment with S.mansoni proteins ameliorated these in vivo and in vitro motility disturbances.In addition,TNBS injection caused a downregulation of effector T cell cytokines after 5 d,whereas a S.mansoni protein effect was no longer observed at this time point. CONCLUSION:Treatment with S.mansoni proteins attenuated intestinal inflammation and ameliorated motility disturbances during murine experimental colitis. | Nathalie E Ruyssers Benedicte Y De Winter Joris G De Man Natacha D Ruyssers Ann J Van Gils Alex Loukas Mark S Pearson Joel V Weinstock Paul A Pelckmans Tom G Moreels | 2010 | World Journal of Gastroenterology2010,16,6: | 11 |
| 5 | Contractile apparatus dysfunction early in the pathophysiology of diabetic cardiomyopathy显示文摘Diabetes mellitus significantly increases the risk of cardiovascular disease and heart failure in patients.Independent of hypertension and coronary artery disease,diabetes is associated with a specific cardiomyopathy,known as diabetic cardiomyopathy(DCM).Four decades of research in experimental animal models and advances in clinical imaging techniques suggest that DCM is a progressive disease,beginning early after the onset of type 1 and type 2 diabetes,ahead of left ventricular remodeling and overt diastolic dysfunction.Although the molecular pathogenesis of early DCM still remains largely unclear,activation of protein kinase C appears to be central in driving the oxidative stress dependent and independent pathways in the development of contractile dysfunction.Multiple subcellular alterations to the cardiomyocyte are now being highlighted as critical events in the early changes to the rate of force development,relaxation and stability under pathophysiological stresses.These changes include perturbed calcium handling,suppressed activity of aerobic energy producing enzymes,altered transcriptional and posttranslational modification of membrane and sarcomeric cytoskeletal proteins,reduced actin-myosin cross-bridge cycling and dynamics,and changed myofilament calcium sensitivity.In this review,we will present and discuss novel aspects of the molecular pathogenesis of early DCM,with a special focus on the sarcomeric contractile apparatus. | Mark T Waddingham Amanda J Edgley Hirotsugu Tsuchimochi Darren J Kelly Mikiyasu Shirai James T Pearson | 2015 | World Journal of Diabetes2015,6,7: | 10 |
| 6 | 胶州湾环境保护法律问题研究显示文摘胶州湾正面临着严重的环境问题,如湿地减少,海域面积不断缩小、纳潮量持续减小;水域污染严重,水质日益恶化;生物资源衰退等,针对这些问题,对涉及胶州湾的各级法律法规进行分析研究,找出了现行法律的欠缺之处:法律体系不完善、海洋执法水平较低、司法救济不足。立法方面,国家立法和地方立法不完善,尚未形成健全有效的胶州湾保护法律体系;执法方面,既往的执法工作取得了积极有效的成果,但执法能力仍然有待提高;司法方面,受制于我国司法体系,司法救济并没有真正到位。针对这些不足提出解决胶州湾法律问题的对策建议,主要有:健全海洋法律体系、提高海洋执法能力、健全司法救济制度。期望为青岛市整治胶州湾环境问题、合理开发利用胶州湾、保护胶州湾海洋环境提供参考。 | 马英杰 吕良爽 Stuart Pearson | 2015 | 海洋科学2015,39,3: | 5 |
| 7 | AONS Ⅱ: Continuing Preservation Software the Trend Towards 'Nirvana'显示文摘File format obsolescence is a major risk factor threatening the sustainability of and access to digital information. While the preservation community has become increasingly interested in tools for migration and transformation of file formats, the National Library of Australia is developing mechanisms specifically focused on monitoring and assessing the risks of file format obsolescence. This paper reports on the AONS II project, undertaken by the National Library of Australia (NLA) in conjunction with the Australian Partnership for Sustainable Repositories (APSR). The project aimed to develop a software tool which allows users to automatically monitor the status of file formats in their repositories, make risk assessments based on a core set of obsolescence risk questions, and receive notifications when file format risks change or other related events occur. This paper calls for the preservation community to develop a co-operating file format obsolescence community which includes registries, software tool creators and end users to effectively curate digital content in order to maintain long-term access. | DAVID PEARSON | 2008 | 现代图书情报技术2008,,1: | 4 |

| 11 | Toll-like receptor 7 deficiency suppresses type 1 diabetes development by modulating B-cell differentiation and function显示文摘Innate immunity mediated by Toll-like receptors(TLRs),which can recognize pathogen molecular patterns,plays a critical role in type 1 diabetes development.TLR7 is a pattern recognition receptor that senses single-stranded RNAs from viruses and host tissue cells;however,its role in type 1 diabetes development remains unclear.In our study,we discovered that Tlr7-deficient(Tlr7^(−/−))nonobese diabetic(NOD)mice,a model of human type 1 diabetes,exhibited a significantly delayed onset and reduced incidence of type 1 diabetes compared with Tlr7-sufficient(Tlr7^(+/+))NOD mice.Mechanistic investigations showed that Tlr7 deficiency significantly altered B-cell differentiation and immunoglobulin production.Moreover,Tlr7^(−/−)NOD B cells were found to suppress diabetogenic CD4^(+)T-cell responses and protect immunodeficient NOD mice from developing diabetes induced by diabetogenic T cells.In addition,we found that Tlr7 deficiency suppressed the antigen-presenting functions of B cells and inhibited cytotoxic CD8^(+)T-cell activation by downregulating the expression of both nonclassical and classical MHC class I(MHC-I)molecules on B cells.Our data suggest that TLR7 contributes to type 1 diabetes development by regulating B-cell functions and subsequent interactions with T cells.Therefore,therapeutically targeting TLR7 may prove beneficial for disease protection. | Juan Huang Jian Peng James Alexander Pearson Georgios Efthimiou Youjia Hu Ningwen Tai Yanpeng Xing Luyao Zhang Jianlei Gu Jianping Jiang Hongyu Zhao Zhiguang Zhou F.Susan Wong Li Wen | 2021 | Cellular & Molecular Immunology2021,18,2: | 3 |

| 14 | Impaired swallowing mechanics of post radiation therapy head and neck cancer patients: A retrospective videofluoroscopic study显示文摘AIM: To determine swallowing outcomes and hyolaryngeal mechanics associated with post radiation therapy head and neck cancer(rt HNC) patients using videofluoroscopic swallow studies. METHODS: In this retrospective cohort study, video-fluoroscopic images of rt HNC patients(n = 21) were compared with age and gender matched controls(n = 21). Penetration-aspiration of the bolus and bolus residue were measured as swallowing outcome variables. Timing and displacement measurements of the anterior and posterior muscular slings elevating the hyolaryngeal complex were acquired. Coordinate data of anatomical landmarks mapping the action of the anterior muscles(suprahyoid muscles) and posterior muscles(long pharyngeal muscles) were used to calculate the distance measurements, and slice numbers were used to calculate time intervals. Canonical variate analysis with post-hoc discriminant function analysis was performed on coordinate data to determine multivariate mechanics of swallowing associated with treatment. Pharyngeal constriction ratio(PCR) was also measured to determine if weak pharyngeal constriction is associated with post radiation therapy.RESULTS: The rt HNC group was characterized by poor swallowing outcomes compared to the control group in regards to: Penetration-aspiration scale(P < 0.0001), normalized residue ratio scale(NRRS) for the valleculae(P = 0.002) and NRRS for the piriform sinuses(P = 0.003). Timing and distance measurements of the anterior muscular sling were not significantly different in the two groups, whereas for the PMS time of displacement was abbreviated(P = 0.002) and distance of excursion was reduced(P = 0.02) in the rt HNC group. A canonical variate analysis shows a significant reduction in pharyngeal mechanics in the rt HNC group(P < 0.0001). The PCR was significantly higher in the test group than the control group(P = 0.0001) indicating reduced efficiency in pharyngeal clearance. CONCLUSION: Using videofluoroscopy, this study shows rt HNC patients have worse swallowing outcomes associated with reduced hyolaryngeal mechanics and pharyngeal constriction compared with controls. | William G Pearson Jr Alisa A Davidoff Zachary M Smith Dorothy E Adams Susan E Langmore | 2016 | World Journal of Radiology2016,8,2: | 2 |

| 16 | NOD2 and ATG16L1 polymorphisms affect monocyte responses in Crohn's disease显示文摘AIM:To assess whether polymorphisms in NOD2 and ATG16L1 affect cytokine responses and mycobacterium avium subspecies paratuberculosis (MAP) survival in monocytes from Crohn's disease (CD) patients.METHODS:Monocytes were isolated from peripheral blood of CD patients of known genotype for common single nucleotide polymorphisms of NOD2 and ATG16L1.Monocytes were challenged with MAP and bacterial persistence assessed at subsequent time-points.Cytokine responses were assayed using a Milliplex multi-analyte profiling assay for 13 cytokines.RESULTS:Monocytes heterozygous for a NOD2 polymorphism (R702W,P268S,or 1007fs) were more permissive for growth of MAP (P=0.045) than those without.There was no effect of NOD2 genotype on subsequent cytokine expression.The T300A polymorphism ofATG16L1 did not affect growth of MAP in our model (P=0.175),but did increase expression of cytokines interleukin (IL)-10 (P=0.047) and IL-6 (P=0.019).CONCLUSION:CD-associated polymorphisms affected the elimination of MAP fromex vivo monocytes (NOD2),or expression of certain cytokines (ATG16L1),implying independent but contributory roles in the pathogenesis of CD. | Dylan M Glubb Richard B Gearry Murray L Barclay Rebecca L Roberts John Pearson Jacqui I Keenan Judy McKenzie Robert W Bentley | 2011 | World Journal of Gastroenterology2011,17,23: | 2 |

| 20 | Light quality and temperature effects on antirrhinum growth and development显示文摘An experiment was carried out to examine the effects of light quality on the growth and development of antirrhinum under three different temperatures 19℃, 24℃ and 27℃ in glasshouses. Five different colour filters (i.e. 'Red absorbing', 'Blue absorbing', 'Blue and Red absorbing' and two 'partially Blue absorbing' materials) were tested, with one clear polythene as a control. Plant height, internode length and leaf area were significantly affected by the spectral filters as well as the temperature.Analysis of color filter's effect on presumed photoreceptors to exist indicated that antirrhinum plant height was regulated by the action of a blue acting photoreceptor (BAP) and not the phytochrome. There was no evidence for an effect ofphytochrome or BAP on time to flowering, however, increasing temperature levels effectively decreased the time to flowering. To predict the effects of different spectral qualities and temperature, simple models were created from data on plant height, internode length and time to flowering. These models were then applied to simulate the potential benefits of spectral filters and temperature in manipulation of growth control and flowering in antirrhinum. | KHATTAK Abdul Mateen PEARSON Simon | 2005 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2005,6,2: | 2 |
