6The wonders of BMP9:From mesenchymal stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism to regenerative medicine显示文摘Although bone morphogenetic proteins(BMPs)initially showed effective induction of ectopic bone growth in muscle,it has since been determined that these proteins,as members of the TGF-b superfamily,play a diverse and critical array of biological roles.These roles include regulating skeletal and bone formation,angiogenesis,and development and homeostasis of multiple organ systems.Disruptions of the members of the TGF-b/BMP superfamily result in severe skeletal and extra-skeletal irregularities,suggesting high therapeutic potential from understanding this family of BMP proteins.Although it was once one of the least characterized BMPs,BMP9 has revealed itself to have the highest osteogenic potential across numerous experiments both in vitro and in vivo,with recent studies suggesting that the exceptional potency of BMP9 may result from unique signaling pathways that differentiate it from other BMPs.The effectiveness of BMP9 in inducing bone formation was recently revealed in promising experiments that demonstrated efficacy in the repair of critical sized cranial defects as well as compatibility with bone-inducing bio-implants,revealing the great translational promise of BMP9.Furthermore,emerging evidence indicates that,besides its osteogenic activity,BMP9 exerts a broad range of biological functions,including stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism.This review aims to summarize our current understanding of BMP9 across biology and the body.Sami Mostafa Mikhail Pakvasa Elam Coalson Allen Zhu Alex Alverdy Hector Castillo Jiaming Fan Alex Li Yixiao Feng Di Wu Elliott Bishop Scott Du Mia Spezia Alissa Li Ofir Hagag Alison Deng Winny Liu Mingyang Li Sherwin S·Ho Aravind Athiviraham Michael J·Lee Jennifer Moriatis Wolf Guillermo A·Ameer Hue H·Luu Rex C·Haydon Jason Strelzow Kelly Hynes Tong-Chuan He Russell R·Reid 2019Genes & Diseases2019,6,3:15
7Diagnostic accuracy of endoscopic ultrasound in pancreatic neuroendocrine tumors: A systematic review and meta analysis显示文摘AIM: To detect pancreatic neuroendocrine tumors (PNETs) has been varied. This study is undertaken to evaluate the accuracy of endoscopic ultrasound (EUS) in detecting PNETs.METHODS: Only EUS studies confirmed by surgery or appropriate follow-up were selected. Articles were searched in Medline, Ovid journals, Medline nonindexed citations, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews. Pooling was conducted by both fixed and random effects model). RESULTS: Initial search identified 2610 reference articles, of these 140 relevant articles were selected and reviewed. Data was extracted from 13 studies (n = 456) which met the inclusion criteria. Pooled sensitivity of EUS in detecting a PNETs was 87.2% (95%CI: 82.2-91.2). EUS had a pooled specificity of 98.0% (95%CI: 94.3-99.6). The positive likelihood ratio of EUS was 11.1 (95%CI: 5.34-22.8) and negative likelihood ratio was 0.17 (95%CI: 0.13-0.24). The diagnostic odds ratio, the odds of having anatomic PNETs in positive as compared to negative EUS studies was 94.7 (95%CI: 37.9-236.1). Begg-Mazumdar bias indicator for publication bias gave a Kendall's tau value of 0.31 (P = 0.16), indication no publication bias. The P for χ2 heterogeneity for all the pooled accuracy estimates was > 0.10. CONCLUSION: EUS has excellent sensitivity and specificity to detect PNETs. EUS should be strongly considered for evaluation of PNETs.Srinivas R Puli Nikhil Kalva Matthew L Bechtold Smitha R Pamulaparthy Micheal D Cashman Norman C Estes Richard H Pearl Fritz-Henry Volmar Sonu Dillon Michael F Shekleton David Forcione 2013World Journal of Gastroenterology2013,19,23:14
8Immune response after photodynamic therapy increases anti-cancer and anti-bacterial effects显示文摘Photodynamic therapy(PDT) is a clinically approved procedure for treatment of cancer and infections. PDT involves systemic or topical administration of a photosensitizer(PS), followed by irradiation of the diseased area with light of a wavelength corresponding to an absorbance band of the PS. In the presence of oxygen, a photochemical reaction is initiated, leading to the generation of reactive oxygen species and cell death. Besides causing direct cytotoxic effects on illuminated tumor cells, PDT is known to cause damage to the tumor vasculature and induce the release of pro-inflammatory molecules. Pre-clinical and clinical studies have demonstrated that PDT is capable of affecting both the innate and adaptive arms of the immune system. Immune stimulatory properties of PDT may increase its beneficial effects giving the therapy wider potential to become more extensively used in clinical practice. Be-sides stimulating tumor-specific cytotoxic T-cells capable to destroy distant untreated tumor cells, PDT leads to development of anti-tumor memory immunity that can potentially prevent the recurrence of cancer. The immunological effects of PDT make the therapy more effective also when used for treatment of bacterial infections, due to an augmented infiltration of neutrophils into the infected regions that seems to potentiate the outcome of the treatment.Eleonora Reginato Peter Wolf Michael R Hamblin 2014World Journal of Immunology2014,4,1:14
9Orbital inflammatory disease:Pictorial review and differential diagnosis显示文摘Orbital inflammatory disease(OID) represents a collec tion of inflammatory conditions affecting the orbit. OID is a diagnosis of exclusion, with the differential diagno sis including infection, systemic inflammatory conditions and neoplasms, among other conditions. Inflammatory conditions in OID include dacryoadenitis, myositis, cel lulitis, optic perineuritis, periscleritis, orbital apicitis, and a focal mass. Sclerosing orbital inflammation is a rare condition with a chronic, indolent course involving dense fibrosis and lymphocytic infiltrate. Previously though to be along the spectrum of OID, it is now considered a distinct pathologic entity. Imaging plays an importan role in elucidating any underlying etiology behind orbita inflammation and is critical for ruling out other condi tions prior to a definitive diagnosis of OID. In this re view, we will explore the common sites of involvemen by OID and discuss differential diagnosis by site and key imaging findings for each condition.Michael N Pakdaman Ali R Sepahdari Sahar M Elkhamary 2014World Journal of Radiology2014,6,4:12
10Osteopontin increases hepatocellular carcinoma cell growth in a CD44 dependant manner显示文摘AIM:To investigate the role of osteopontin(OPN) and its splice variants in the proliferation of hepatocellular carcinoma(HCC).METHODS:The expression of OPN variants in HCC cell lines as well as HCC tissue samples and nontumour tissue was studied using polymerase chain reaction.OPN variant cDNAs were cloned into a mammalian expression vector allowing both transient expression and the production of stable OPN expressing cell lines.OPN expression was studied in these cells using Western blotting,immunofluoresnce and enzyme linked immunosorbent assay.A CD44 blocking antibody and siRNA targeting of CD44 were used to examine the role of this receptor in the OPN stimulated cell growth observed in culture.Huh-7 cells stably expressing either OPN-A,-B or-C were injected subcutaneously into the flanks of nude mice to observe in vivo tumour growth.Expression of OPN mRNA and protein in these tumours was examined using reverse transcriptionpolymerase chain reaction and immunohistochemistry.RESULTS:OPN is expressed in HCC in 3 forms,the full length OPN-A and 2 splice variants OPN-B and-C.OPN variant expression was noted in HCC tissue as well as cognate surrounding cirrhotic liver tissue.Expression of these OPN variants in the HCC derived cell line Huh-7 resulted in secretion of OPN into the culture medium.Transfer of OPN conditioned media to na ve Huh-7 and HepG2 cells resulted in significant cell growth suggesting that all OPN variants can modulate cell proliferation in a paracrine manner.Furthermore the OPN mediated increase in cellular proliferation was dependent on CD44 as only CD44 positive cell lines responded to OPN conditioned media while siRNA knockdown of CD44 blocked the proliferative effect.OPN expression also increased the proliferation of Huh-7 cells in a subcutaneous nude mouse tumour model,with Huh-7 cells expressing OPN-A showing the greatest proliferative effect.CONCLUSION:This study demonstrates that OPN plays a significant role in the proliferation of HCC through interaction with the cell surface receptor CD44.Modulation of this interaction could represent a novel strategy for the control of HCC.Renee J Phillips Karla J Helbig Kylie H Van der Hoek Devanshi Seth Michael R Beard 2012World Journal of Gastroenterology2012,18,26:12
11Effect of transjugular intrahepatic portosystemic shunt on pulmonary gas exchange in patients with portal hypertension and hepatopulmonary syndrome显示文摘AIM: To assess the impact of transjugular intrahepatic portosystemic shunt (TIPS) on pulmonary gas exchange and to evaluate the use of TIPS for the treatment of hepatopulmonary syndrome (HPS).METHODS: Seven patients, three of them with advanced HPS, in whom detailed pulmonary function tests were performed before and after TIPS placementat the University of Alabama Hospital and at the Hospital Clinic, Barcelona, were considered.RESULTS: TIPS patency was confirmed by hemodynamic evaluation. No changes in arterial blood gases were observed in the overall subset of patients. Transient arterial oxygenation improvement was observed in only one HPS patient, early after TIPS, but this was not sustained 4 mo later.CONCLUSION: TIPS neither improved nor worsened pulmonary gas exchange in patients with portal hypertension. This data does not support the use of TIPS as a specific treatment for HPS. However, it does reinforce the view that TIPS can be safely performed for the treatment of other complications of portal hypertension in patients with HPS.Graciela Martínez-Pallí Britt B Drake Joan-Carles García-Pagán Joan-Albert Barberà Miguel R Arguedas Robert Rodriguez-Roisin Jaume Bosch Michael B Fallon 2005World Journal of Gastroenterology2005,11,43:11
12动态概率神经网络及油气概率分布预测显示文摘传统概率神经网络(PNN)采用了前向径向基函数神经网络的局部化的、高斯型作用函数,虽然具有较好的分类能力,但也存在以下局限性:①如果学习样本增多,模式层的神经元个数也增多,导致运算矩阵的增大而使之几乎丧失处理大数据量实际资料的能力;②模式层到求和层的权值固定为常数,必然要求学习集合中各类样本的数量相等,从而会影响其接受实际数据的能力。为此文中引入了动态概率神经网络(DPNN),它与传统PNN在结构上的区别在于:①模式层到求和层不以等权连接,权值由学习样本集的概率分布所确定;②学习样本集中各类样本的数量(各类在模式层的神经元个数)可以不相等。文中还介绍了DPNN算法。理论数据测试充分展示了DPNN结构具有动态调整、学习收敛快速、分类识别能力强大等特点。通过选取G油田实际资料的22种属性作为网络的输入向量,用DPNN进行分类识别得到了含油气概率分布图,可为预测有利油气圈闭及油水分布规律提供依据。徐旺林 庞雄奇 吕淑英 Michael R Berthold 2005石油地球物理勘探2005,40,1:11
13Transcriptomic landscape regulated by the 14 types of bone morphogenetic proteins(BMPs)in lineage commitment and differentiation of mesenchymal stem cells(MSCs)显示文摘Mesenchymal stem cells(MSCs)are ubiquitously-existing multipotent progenitors that can self-renew and differentiate into multiple lineages including osteocytes,chondrocytes,adipocytes,tenocytes and myocytes.MSCs represent one of the most commonly-used adult progenitors and serve as excellent progenitor cell models for investigating lineagespecific differentiation regulated by various cellular signaling pathways,such as bone morphogenetic proteins(BMPs).As members of TGFb superfamily,BMPs play diverse and important roles in development and adult tissues.At least 14 BMPs have been identified in mammals.Different BMPs exert distinct but overlapping biological functions.Through a comprehensive analysis of 14 BMPs in MSCs,we demonstrated that BMP9 is one of the most potent BMPs in inducing osteogenic differentiation of MSCs.Nonetheless,a global mechanistic view of BMP signaling in regulating the proliferation and differentiation of MSCs remains to be fully elucidated.Here,we conducted a comprehensive transcriptomic profiling in the MSCs stimulated by 14 types of BMPs.Hierarchical clustering analysis classifies 14 BMPs into three subclusters:an osteo/chondrogenic/adipogenic cluster,a tenogenic cluster,and BMP3 cluster.We also demonstrate that six BMPs(e.g.,BMP2,BMP3,BMP4,BMP7,BMP8,and BMP9)can induce ISmads effectively,while BMP2,BMP3,BMP4,BMP7,and BMP11 up-regulate Smad-independent MAP kinase pathway.Furthermore,we show that many BMPs can upregulate the expression of the signal mediators of Wnt,Notch and PI3K/AKT/mTOR pathways.While the reported transcriptomic changes need to be further validated,our expression profiling represents the first-of-its-kind to interrogate a comprehensive transcriptomic landscape regulated by the 14 types of BMPs in MSCs.Linghuan Zhang Qing Luo Yi Shu Zongyue Zeng Bo Huang Yixiao Feng Bo Zhang Xi Wang Yan Lei Zhenyu Ye Ling Zhao Daigui Cao Lijuan Yang Xian Chen Bin Liu William Wagstaff Russell R*Reid Hue H*Luu Rex C*Haydon Michael J*Lee Jennifer Moriatis Wolf Zhou Fu Tong-Chuan He Quan Kang 2019Genes & Diseases2019,6,3:11
14An acorn squash (Cucurbita pepo ssp. ovifera) fruit and seed transcriptome as a resource for the study of fruit traits in Cucurbita显示文摘Acorn squash(Cucurbita pepo)is an iconic fall vegetable in the United States,known for its unique fruit shape and also prized for its culinary properties.Little is known about the metabolism that underlies the development of fruit quality attributes such as color,sweetness,texture and nutritional qualities in acorn squash,or any other winter squash grown worldwide.To provide insight into winter squash fruit and seed development and add to the genomic resources in the Cucurbita genus,RNA sequencing was used to generate an acorn squash fruit and seed transcriptome from the cultivar Sweet REBA at critical points throughout fruit development.141838600 high-quality paired-end Illumina reads were assembled into 55949 unigenes.85%of unigenes with predicted open reading frames had homology with previously identified genes and over 62%could be functionally annotated.Comparison with the watermelon and cucumber genomes provided confirmation that the unigenes are full-length and comprehensive,covering an average of 90%of the coding sequence of their homologs and 72%of the cucumber and watermelon exomes.Key candidate genes associated with carotenoid and carbohydrate metabolism were identified toward a resource for winter squash fruit quality trait dissection.This transcriptome represents a major advance in C.pepo genomics,providing significant new sequence information and revealing the repertoire of genes expressed throughout winter squash fruit and seed development.Future studies on the genetic basis of fruit quality and future breeding efforts will be enhanced by tools and insights developed from this resource.Lindsay E Wyatt Susan R Strickler Lukas A Mueller Michael Mazourek 2015Horticulture Research2015,2,1:11
15Inflammatory bowel disease serology in Asia and the West显示文摘AIM:To study serological antibodies in Caucasians and Asians,in health and inflammatory bowel disease(IBD),in Australia and Hong Kong(HK).METHODS:Anti-glycan antibodies[anti-chitobioside(ACCA),anti-laminaribioside(ALCA)],and anti-mannobioside(AMCA),anti-Saccharomyces cervisiae(gASCA);and atypical perinuclear anti-neutrophil cytoplasmic antibody(pANCA)were tested in IBD patients,their unaffected relatives,and healthy controls in Australia and HK(China).Antibody status(positive or negative)and titre was compared between subjects of different geography,ethnicity and disease state.RESULTS:Ninety subjects were evaluated:21 Crohn’s disease(CD),32 ulcerative colitis(UC),29 healthy controls,and 8 IBD patient relatives.Forty eight subjects were Australian(29 Caucasian and 19 ethnic Han Chinese)and 42 were from HK(all Han Chinese).Caucasian CD patients had a significantly higher antibody prevalence of gASCA(67%vs 3%,P<0.001),ALCA(44%vs 6%,P=0.005),and AMCA(67%vs 15%,P=0.002),whereas HK CD patients had a higher prevalence of only AMCA(58%vs 25%,P=0.035),when compared with UC and healthy subjects in both countries.Caucasian CD had significantly higher gASCA prevalence(67%vs 0%,P<0.001)and titre(median59 vs 9,P=0.002)than HK CD patients.Prevalence and titres of ALCA,ACCA and AMCA did not differ between CD in the two countries.Presence of at least one antibody was higher in Caucasian than HK CD patients(100%vs 58%,P=0.045).pANCA did not differ between countries or ethnicity.CONCLUSION:Serologic CD responses differ between HK Asian and Australian Caucasian patients.Different genetic,environmental or disease pathogenic factors may account for these differences.Lani Prideaux Michael A Kamm Peter De Cruz Daniel R van Langenberg Siew C Ng Iris Dotan 2013World Journal of Gastroenterology2013,19,37:10
16定量药理学:一个促进药物开发及转换型研究严谨思考的多学科领域显示文摘尽管从事定量药理学研究的科学工作者一再强调将定量分析的原则应用于促进新药研发的决策,定量药理学的发展还是超过了上述领域。普通研究和决策领域总是期望着常规和传统的研究范例发生进步,当与定量药理学相关的领域自身在发展并与其交互作用时,自然便产生对临床药理学的协同作用。创新性和可塑性训练计划和策略均是将来临床研究工作中必不可少的要素。掌握定量药理学领域的知识成为对药理科学家的要求,具有定量药理学背景的人员可望获得更高的薪水。目前定量药理学相关培训计划,教学资料,及学术权威均比较贫乏,学生们可以从企业化、调控性的背景的教师等多种机构的教职员那获得指导,此外也可以通过在线课程,可视化教学进修课程,与他们的导师保持联系。对课程和学位的管理可以采取灵活的态度,这样可在短期内培养更多的定量药理学工作者。Jeffrey S Barrett Michael J Fossler K.David Cadieu Marc R Gastonguay 沈杰 谢海棠 孙瑞元 2008中国临床药理学与治疗学2008,13,5:10
17Total pancreatectomy and islet autotransplantation: A decade nationwide analysis显示文摘AIM: To investigate outcomes and predictors of inhospital morbidity and mortality after total pancreatectomy(TP) and islet autotransplantation. METHODS: The nationwide inpatient sample(NIS) database was used to identify patients who underwent TP and islet autotransplantation(IAT) between 2002-2012 in the United States. Variables of interest were inherent variables of NIS database which included demographic data(age, sex, and race), comorbidities(such as diabetes mellitus, hypertension, and deficiency anemia), and admission type(elective vs nonelective). The primary endpoints were mortality and postoperative complications according to the ICD-9 diagnosis codes which were reported as the second to 25 th diagnosis of patients in the database. Risk adjusted analysis was performed to investigate morbidity predictors. Multivariate regression analysis was used to identify predictors of in-hospital morbidity.RESULTS: We evaluated a total of 923 patients who underwent IAT after pancreatectomy during 2002-2012. Among them, there were 754 patients who had TP + IAT. The most common indication ofsurgery was chronic pancreatitis(86%) followed by acute pancreatitis(12%). The number of patients undergoing TP + IAT annually significantly increased during the 11 years of study from 53 cases in 2002 to 155 cases in 2012. Overall mortality and morbidity of patients were 0% and 57.8 %, respectively. Postsurgical hypoinsulinemia was reported in 42.3% of patients, indicating that 57.7% of patients were insulin independent during hospitalization. Predictors of inhospital morbidity were obesity [adjusted odds ratio(AOR): 3.02, P = 0.01], fluid and electrolyte disorders(AOR: 2.71, P < 0.01), alcohol abuse(AOR: 2.63, P < 0.01), and weight loss(AOR: 2.43, P < 0.01). CONCLUSION: TP + IAT is a safe procedure with no mortality, acceptable morbidity, and achieved high rate of early insulin independence. Obesity is the most significant predictor of in-hospital morbidity.Reza Fazlalizadeh Zhobin Moghadamyeghaneh Aram N Demirjian David K Imagawa Clarence E Foster Jonathan R Lakey Michael J Stamos Hirohito Ichii 2016World Journal of Transplantation2016,6,1:9
18Gastrointestinal neuroendocrine tumors treated with high dose octreotide-LAR:A systematic literature review显示文摘AIM:To review literature on efficacy and safety of octreotide-long-acting repeatable(LAR)used at doses higher than the Food and Drug Administration(FDA)-approved 30 mg/mo for treatment of neuroendocrine tumors(NETs).METHODS:We searched Pub Med and Cochrane Library from 1998-2012,5 conferences(American Society of Clinical Oncology,Endocrine Society,European Neuroendocrine Tumor Society,European Society for Medical Oncology,North American Neuroendocrine Tumor Society)from 2000-2013 using Me SH and keyterms including neuroendocrine tumors,carcinoid tumor,carcinoma,neuroendocrine,and octreotide.Bibliographies of accepted articles were also searched.Two reviewers reviewed titles,abstracts,and full-length articles.Studies that reported data on efficacy and safety of≥30 mg/mo octreotide-LAR for NETs in human subjects,published in any language were included in the review.RESULTS:The search identified 1086 publications,of which 238 underwent full-text review(20 were translated into English);17 were included in the review.Studies varied in designs,subjects,octreotide-LAR regimens,and definition of outcomes.Eleven studies reported use of higher doses to control symptoms and tumor progression,although symptom severity and formal quality-of-life analysis were not quantitatively measured.Ten studies reported efficacy,describing 260 subjects with doses ranging from 40 mg/mo or 30 mg/3 wk up to 120 mg/mo.Eight studies reported expert clinical opinion that supported dose escalation of octreotide-LAR up to 60 mg/mo for symptom control and suggested increased doses may be effective at preventing tumor progression.Eight studies reported safety;there was no evidence of increased toxicity associated with doses of octreotide-LAR>30 mg/mo.CONCLUSION:As reported in this review,octreotide-LAR at doses>30 mg/mo is being prescribed for symptom and tumor control in NET patients.Furthermore,expert clinical opinion provided support for escalation of somatostatin analogs for refractory hormonal symptoms.Michael S Broder David Beenhouwer Jonathan R Strosberg Maureen P Neary Dasha Cherepanov 2015World Journal of Gastroenterology2015,21,6:8

20Mutants, Overexpressors, and Interactors of Arabidopsis Plastocyanin Isoforms: Revised Roles of Plastocyanin in Photosynthetic Electron Flow and Thylakoid Redox State显示文摘二相应 plastocyanin isoforms 被基因 PETE1 和 PETE2 编码为 Arabidopsis thaliana 的原子染色体。PETE2 抄本被表示在更加高水平和 PETE2 蛋白质是更丰富的 isoform。在 PETE 基因的空变化导致了植物,指明的 pete1 和 pete2,与减少的 plastocyanin 内容。尽管有在超过 90% 减少 plastocyanin 层次,而 pete1 大美人种,然而,它的自己上的一个 pete2 0 变化仅仅稍微影响光合作用和生长的率,与大约 6080% 野类型的 plastocyanin 水平,没显示出任何改变。因此, plastocyanin 集中不在最佳的生长条件下面为光合的电子流动正在限制,也许为蛋白质暗示另外的可能的生理的角色。确实, plastocyanin 以前被建议了在 thylakoid 氧化还原作用反应与细胞色素 c6A (Cyt c6A ) 合作,但是我们不为在二蛋白质之间的一个物理相互作用发现证据,用在酵母的相互作用试金。我们在酵母相互作用试金观察了 Cyt c6A 的 homodimerization,而且 Cyt c6A homodimers 没能与 plastocyanin 交往。而且, atc6-1 pete1 的 phenotypic 分析和 atc6-1 pete2 加倍异种,每缺乏的 Cyt c6A 并且二编码 plastocyanin 基因之一,没能揭示任何基因相互作用。在 pete1 pete2 的 PETE1 或 PETE2 的 Overexpression 在实质上野类型的光合的性能的两倍猛烈变异的背景结果,排除二 plastocyanin isoforms 能在 thylakoid 有不同函数的可能性电子流动。Paolo Pesaresi Michael Scharfenberg Martin Weigel Irene Granlund Wolfgang R Schroder Giovanni Finazzi Fabrice Rappaport Simona Masiero Antonella Furini Peter Jahns Dario Leister 2009Molecular Plant2009,2,2:7
