| 1 | Molecular mechanisms of mesenchymal stem cell differentiation towards osteoblasts显示文摘Bone is a dynamic tissue that is constantly renewed by the coordinated action of two cell types, i.e., the bone-resorbing osteoclasts and the bone-forming osteoblasts. However, in some circumstances, bone regeneration exceeds bone self repair capacities. This is notably often the case after bone fractures, osteolytic bone tumor surgery, or osteonecrosis. In this regard,bone tissue engineering with autologous or allogenic mesenchymal stem cells(MSCs) is been widely developed. MSCs can be isolated from bone marrow or other tissues such as adipose tissue or umbilical cord, and can be implanted in bone defects with or without prior amplification and stimulation. However, the outcome of most pre-clinical studies remains relatively disappointing. A better understanding of the successive steps and molecular mechanisms involved in MSC-osteoblastic differentiation appears to be crucial to optimize MSC-bone therapy. In this review, we first present the important growth factors that stimulate osteoblastogenesis. Then we review the main transcription factors that modulate osteoblast differentiation, and the microRNAs(miRs)that inhibit their expression. Finally, we also discuss articles dealing with the use of these factors and miRs in the development of new bone MSC therapy strategies. We particularly focus on the studies using human MSCs, since significant differences exist between osteoblast differentiation mechanisms in humans and mice for instance. | Maya Fakhry René Buchet David Magne Eva Hamade Bassam Badran | 2013 | World Journal of Stem Cells2013,5,4: | 32 |

| 4 | Short-type single balloon enteroscope for endoscopic retrograde cholangiopancreatography with altered gastrointestinal anatomy显示文摘AIM:To evaluate the effectiveness of a short-type single-balloon-enteroscope(SBE) for endoscopic retrograde cholangiopancreatography(ERCP) in patients with a reconstructed intestine.METHODS:Short-type SBE was developed to perform ERCP in postoperative patients with a reconstructed intestine.Short-type SBE is a direct-viewing endoscope with the following specifications:working length,1520 mm;total length,1840 mm;channel diameter,3.2 mm.In addition,short-type SBE has a water-jet channel.The study group comprised 22 patients who underwent 31 sessions of short-type SBE-assisted ERCP from June 2011 through May 2012.Reconstruction was performed by Billroth-Ⅱ(B-Ⅱ) gastrectomy in 6 patients(8 sessions),Roux-en-Y(R-Y) gastrectomy in 14 patients(21 sessions),and R-Y hepaticojejunostomy in 2 patients(2 sessions).We retrospectively studied the rate of reaching the blind end(papilla of Vater or choledochojejunal anastomosis),mean time required to reach the blind end,diagnostic success rate(defined as the rate of successfully imaging the bile and pancreatic ducts),therapeutic success rate(defined as the rate of successfully completing endoscopic treatment),mean procedure time,and complications.RESULTS:Among the 31 sessions of ERCP,the rate of reaching the blind end was 88% in B-Ⅱ gastrectomy,91% in R-Y gastrectomy,and 100% in R-Y hepaticojejunostomy.The mean time required to reach the papilla was 18.3 min in B-Ⅱ gastrectomy,21.1 min in R-Y gastrectomy,and 32.5 min in R-Y hepaticojejunostomy.The diagnostic success rates in all patients and those with an intact papilla were respectively 86% and 86% in B-Ⅱ gastrectomy,90% and 87% in R-Y gastrectomy,and 100% in R-Y hepaticojejunostomy.The therapeutic success rates in all patients and those with an intact papilla were respectively 100% and 100% in B-Ⅱ gastrectomy,94% and 92% in R-Y gastrectomy,and 100% in R-Y hepaticojejunostomy.Because the channel diameter was 3.2 mm,stone extraction could be performed with a wire-guided basket in 12 sessions,and wireguided intraductal ultrasonography could be performed in 8 sessions.As for complications,hyperamylasemia(defined as a rise in serum amylase levels to more than 3 times the upper limit of normal) occurred in 1 patient(7 sessions) with a B-Ⅱ gastrectomy and 4 patients(19 sessions) with an R-Y gastrectomy.After ERCP in patients with an R-Y gastrectomy,2 patients(19 sessions) had pancreatitis,1 patient(21 sessions) had gastrointestinal perforation,and 1 patient(19 sessions) had papillary bleeding.Pancreatitis and bleeding were both mild.Gastrointestinal perforation improved after conservative treatment.CONCLUSION:Short-type SBE is effective for ERCP in patients with a reconstructed intestine and allows most conventional ERCP devices to be used. | Hiroshi Yamauchi Mitsuhiro Kida Kosuke Okuwaki Shiro Miyazawa Tomohisa Iwai Miyoko Takezawa Hidehiko Kikuchi Maya Watanabe Hiroshi Imaizumi Wasaburo Koizumi | 2013 | World Journal of Gastroenterology2013,19,11: | 10 |
| 5 | Stress ulcer prophylaxis guidelines:Are they being implemented in Lebanese health care centers?显示文摘AIM:To evaluate the current practice of stress ulcer prophylaxis (SUP) in Lebanese Health care centers.METHODS:A multi-center prospective chart review study was conducted over 8 mo.A questionnaire was distributed to pharmacy students who collected data on demographics,SUP medications,dose,route,duration and associated risk factors.The appropriateness of SUP use was determined as per American Society of Health-System Pharmacists guidelines.Institutional review board approval was obtained from each hospital center.RESULTS:A total of 1004 patients were included.67% of the patients who received prophylaxis did not have an indication for SUP.The majority (71.6%) of the patients who were administered parenteral drugs can tolerate oral medications.Overall,the regimen of acid-suppressant drugs was suboptimal in 87.6% of the sample.This misuse was mainly observed in non-teaching hospitals.CONCLUSION:This study highlighted the need,in Lebanese hospitals,to establish clinical practice guidelines for the use of SUP;mainly in non-critical care settings. | Abeer Zeitoun Maya Zeineddine Hani Dimassi | 2011 | World Journal of Gastrointestinal Pharmacology and Therapeutics2011,2,4: | 10 |
| 6 | Association of Streptococcus bovis presence in colonic content with advanced colonic lesion显示文摘AIM:To prospectively examine the association between presence of Streptococcus bovis(S.bovis)in colonic suction fluid and the endoscopic findings on colonoscopy.METHODS:From May 2012 to March 2013,203 consecutivepatients who underwent colonoscopy for any reason were enrolled in the study.Exclusion criteria included:antibiotic use in the previous month,age younger than18 years,and inadequate preparation for colonoscopy.The colonoscopy was performed for the total length of the colon or to the occluding tumor.The endoscopic findings were registered.Samples were obtained proximal to the colonoscopic part of the suction tube from each patient and sent to the clinical microbiology laboratory for isolation and identification of S.bovis.Samples were incubated in enrichment media with addition of antibiotic disks for inhibition of growth of Gram-negative rods.The samples were seeded on differential growth media;suspected positive colonies were isolated and identified with Gram staining,catalase,and pyrrolidonyl arylamidase tests,and further identified using a VITEK2 system.Statistical analyses were performed using the Student’s t andχ2 tests.RESULTS:Of the 203 patients recruited,49(24%)patients were found to be S.bovis carriers;of them,the endoscopic findings included:17(34.7%)cases with malignant tumors,11(22.4%)with large polyps,5(10.2%)with medium-sized polyps,6(12.2%)with small polyps,4(8.1%)with colitis,and 6(12.2%)normal colonoscopies.Of 154 patients found negative for S.bovis,the endoscopic findings included:none with malignant tumors,9(5.8%)cases with large polyps,11(7.1%)with medium-sized polyps,26(16.9%)with small polyps,7(4.5%)with colitis,and101(65.6%)normal colonoscopies.S.bovis(Grampositive coccus)is considered part of the normal intestinal flora.There is an association between S.bovis bacteremia and colonic neoplasia.It is not well understood whether the bacterium has a pathogenetic role in the development of neoplasia or constitutes an epiphenomenon of colorectal neoplasms.There was a clear relationship between positivity for S.bovis in colonic suction fluid and findings of malignant tumors and large polyps in the colon.CONCLUSION:There is an association between S.bovis bacteremia and malignant colonic lesions;this should prompt for development of a reliable screening method for advanced colonic lesions. | Maya Paritsky Nina Pastukh Diana Brodsky Natalya Isakovich Avi Peretz | 2015 | World Journal of Gastroenterology2015,21,18: | 9 |

| 8 | An Alzheimer's Disease-Relevant Presenilin-1 Mutation Augments Amyloid-Beta-Induced Oligodendrocyte Dysfunction显示文摘研究表明,家族性阿尔茨海默病(FAD)患者处于无症状或临床前阶段时,脑白质即出现病理改变。此种改变在髓鞘破坏及阿尔茨海默病(AD)病理生理中的作用有待进一步研究阐明。笔者前期研究证实,三重转基因AD小鼠(人淀粉前体蛋白基因的Swedish突变,早老素-1 M146V(PS1M146V)敲入突变及tauP301L突变)表现出类似FAD患者的髓鞘破坏,Aβ1-42促进了白质病变。本研究离体实验证实,PS1M146V变异导致小鼠少突胶质前体细胞在分化过程中易出现类似Aβ1-42诱导的变化。PS1M146V的表达损伤少突胶质前体细胞的功能并影响髓鞘碱性蛋白的分布,暴露于Aβ1-42加重此影响。由PS1M146V及Aβ1-42导致的髓鞘破坏及髓鞘碱性蛋白在亚细胞结构中的误定位可被TWS119(糖原合成激酶(GSK)-3β抑制剂)抑制,提示GSK-3β激酶活动在此病理过程中有重要作用。综上所述,本研究有助于增加对AD早期无症状阶段,由PS1M146V及Aβ1-42导致少突胶质细胞功能异常及髓鞘损伤的机制的理解,并提供了针对少突胶质细胞预防AD相关白质病变的新的治疗靶点。 | MAYA K.DESAI BRENDAN J.GUERCIO WADE C.NARROW WILLIAM J.BOWERS | 2011 | 神经损伤与功能重建2011,6,2: | 6 |
| 9 | The role of DJ-1 in the oxidative stress cell death cascade after stroke显示文摘Oxidative stress is closely associated with secondary cell death in many disorders of the central nervous system including stroke,Parkinson’s disease,Alzheimer’s disease.Among many aberrant oxidative stress-associated proteins,DJ-1 has been associated with the oxidative stress cell death cascade primarily in Parkinson’s disease.Although principally expressed in the cytoplasm and nucleus,DJ-1 can be secreted into the serum under pathological condition.Recently,a close pathological association between DJ-1 and oxidative stress in stroke has been implicated.To this end,we and others have demonstrated the important role of mitochondria in neuroprotection for stroke by demonstrating that the translocation of DJ-1 in the mitochondria could potentially mitigate mitochondrial injury.Here,we discuss our recent findings testing the hypothesis that DJ-1 not only functions as a form of intracellular protection from oxidative stress,but that it also utilizes paracrine and/or autocrine cues in order to accomplish extracellular signaling between neighboring neuronal cells,resulting in neuroprotection.This article highlights recent evidence supporting the status of DJ-1 as key anti-oxidative stress therapeutic target for stroke. | Paolina Pantcheva Maya Elias Kelsey Duncan Cesar V.Borlongan Naoki Tajiri Yuji Kaneko | 2014 | Neural Regeneration Research2014,9,15: | 5 |
| 10 | Predictors of disease severity in ulcerative colitis patients from Southwestern Ontario显示文摘AIM:To understand the demographic characteristics of patients in Southwestern Ontario,Canada with ulcerative colitis(UC)in order to predict disease severity. METHODS:Records from 1996 to 2001 were exam- ined to create a database of UC patients seen in the London Health Sciences Centre South Street Hospital Inflammatory Bowel Disease Clinic.To be included, patients'charts were required to have information of their disease presentation and a minimum of 5 years of follow-up.Charts were reviewed using standardized data collection forms.Disease severity was generated during the chart review process,and non-endoscopic Mayo Score criteria were collected into a composite. RESULTS:One hundred and two consecutive patients'data were entered into the database.Demographic analyses revealed that 51%of the patients were male, the mean age at diagnosis was 39 years,13.7%had a first degree relative with inflammatory bowel disease (IBD),61.8%were nonsmokers and 24.5%were ex-smokers.In 22.5%of patients the disease was limited to the rectum,in 21.6%disease was limited to the sigmoid colon,in 22.5%disease was limited to the left colon,and 32.4%of patients had pancolitis. Standard multiple regression analysis which regressed a composite of physician global assessment of disease severity,average number of bowel movements,and average amount of blood in bowel movements on year of diagnosis and age at time of diagnosis was significant,R 2=0.306,F(7,74)=4.66,P<0.01. Delay from symptoms to diagnosis of UC,gender, family history of IBD,smoking status and disease severity at the time of diagnosis didnot significantly predict the composite measure. CONCLUSION:UC severity is associated with younger age at diagnosis and year of diagnosis in a longitudinal cohort of UC patients,and may identify prognostic UC indicators. | Lee S Roth Nilesh Chande Terry Ponich Maya L Roth James Gregor | 2010 | World Journal of Gastroenterology2010,16,2: | 4 |
| 11 | Multimodal alarm behavior in urban and rural gray squirrels studied by means of observation and a mechanical robot显示文摘Urbanization of animal habitats has the potential to affect the natural communication systems of any species able tosurvive in the changed environment. Urban animals such as squirrels use multiple signal channels to communicate, but it is unknownhow urbanization has affected these behaviors. Multimodal communication, involving more than one sensory modality,can be studied by use of biomimetic mechanical animal models that are designed to simulate the multimodal signals and be presentedto animal subjects in the field. In this way the responses to the various signal components can be compared and contrastedto determine whether the multimodal signal is made up of redundant or nonredundant components. In this study, we presentedwild gray squirrels in relatively urban and relatively rural habitats in Western Massachusetts with a biomimetic squirrel modelthat produced tail flags and alarm barks in a variety of combinations. We found that the squirrels responded to each unimodalcomponent on its own, the bark and tail flag, but they responded most to the complete multimodal signal, containing both theacoustic and the moving visual components, providing evidence that in this context the signal components are redundant and thattheir combination elicits multimodal enhancement. We expanded on the results of Partan et al. (2009) by providing data on signalingbehavior in the presence and absence of conspecifics, suggesting that alarm signaling is more likely if conspecifics arepresent. We found that the squirrels were more active in the urban habitats and that they responded more to tail flagging in theurban habitats as compared to the rural ones, suggesting the interesting possibility of a multimodal shift from reliance on audio tovisual signals in noisier more crowded urban habitats [Current Zoology 56 (3): 313-326, 2010]. | Sarah R.PARTAN Andrew G FULMER Maya A.M.GOUNARD Jake E.REDMOND | 2010 | Current Zoology2010,56,3: | 4 |
| 12 | 氨基酮戊酸光动力疗法抑制成纤维细胞生长因子10诱导的HaCaT细胞过度角化及增殖的机制研究显示文摘目的 探讨氨基酮戊酸光动力疗法(ALA-PDT)对成纤维细胞生长因子10(FGF-10)诱导的HaCaT细胞过度角化及增殖的作用及其机制。 方法 将培养的HaCaT细胞分为4组:空白对照组(无任何处理),FGF-10组(加入FGF-10孵育24 h),ALA-PDT组(ALA孵育24 h后红光照射),FGF-10 + ALA-PDT组(FGF-10孵育24 h后,再加ALA孵育24 h,红光照射)。用CCK-8法检测各组细胞增殖活性,Western印迹法检测K1、K6、K16及角质形成细胞生长因子受体(KGFR)的含量,ELISA法检测各组细胞上清液中白细胞介素1α(IL-1α)蛋白表达,免疫荧光检测各组细胞KGFR和K6蛋白表达水平。统计学分析采用析因设计的方差分析和单因素方差分析。结果 析因分析显示,ALA-PDT和FGF-10对HaCaT细胞增殖无交互作用(F交互 = 1.369,P = 0.276),FGF-10对HaCaT细胞增殖有促进作用(FFGF-10 = 20.853,P 〈 0.05),而ALA-PDT有抑制作用(FALA-PDT = 24.822,P 〈 0.05)。与空白对照组细胞增殖活性(A值为0.924 ± 0.024)比较,FGF-10组(1.233 ± 0.099)显著升高(P 〈 0.05),而ALA-PDT组(0.718 ± 0.107)显著降低(P 〈 0.05),FGF-10 + ALA-PDT组(0.901 ± 0.014)较FGF-10组显著降低(P 〈 0.05)。Western印迹法显示,FGF-10可促进K1、K6、K16蛋白和KGFR的表达(均P 〈 0.05),而ALA-PDT抑制这些蛋白的表达(均P 〈 0.05),FGF-10 + ALA-PDT组K1、K6、K16和KGFR的相对表达量与FGF-10组比较均显著降低(均P 〈 0.05)。ELISA法显示,FGF-10会增加HaCaT细胞IL-1α蛋白分泌(P 〈 0.05),但ALA-PDT对其没有影响(P = 0.467)。此外,免疫荧光检测显示,FGF-10增加HaCaT细胞K6和KGFR免疫荧光强度(P 〈 0.05),而ALA-PDT降低K6和KGFR免疫荧光强度(P 〈 0.05),FGF-10 + ALA-PDT组K6和KGFR免疫荧光强度显著低于FGF-10组(P 〈 0.05)。 结论 ALA-PDT能抑制FGF-10诱导的HaCaT细胞过度角化及增殖,其机制与下调K1、K6、K16、KGFR及IL-1α有关。 | 易飞 Maya Valeska Gozali 张家安 周炳荣 骆丹 张丽超 王申 刘娟 吴红巾 | 2015 | 中华皮肤科杂志2015,48,11: | 4 |

| 15 | Mapping novel genetic loci associated with female liver weight variations using Collaborative Cross mice显示文摘Background: Liver weight is a complex trait, controlled by polygenic factors and differs within populations. Dissecting the genetic architecture underlying these variations will facilitate the search for key role candidate genes involved directly in the hepatomegaly process and indirectly involved in related diseases etiology.Methods: Liver weight of 506 mice generated from 39 different Collaborative Cross(CC) lines with both sexes at age 20 weeks old was determined using an electronic balance. Genomic DNA of the CC lines was genotyped with high-density single nucleotide polymorphic markers.Results: Statistical analysis revealed a significant(P < 0.05) variation of liver weight between the CC lines, with broad sense heritability(H^2) of 0.32 and genetic coefficient of variation(CV_G) of 0.28. Subsequently, quantitative trait locus(QTL) mapping was performed, and results showed a significant QTL only for females on chromosome 8 at genomic interval 88.61-93.38 Mb(4.77 Mb). Three suggestive QTL were mapped at chromosomes 4, 12 and 13. The four QTL were designated as LWL1-LWL4 referring to liver weight loci 1-4 on chromosomes 8, 4, 12 and 13,respectively.Conclusion: To our knowledge, this report presents, for the first time, the utilization of the CC for mapping QTL associated with baseline liver weight in mice. Our findings demonstrate that liver weight is a complex trait controlled by multiple genetic factors that differ significantly between sexes. | Hanifa J.Abu-Toamih Atamni Maya Botzman Richard Mott Irit Gat-Viks Fuad A.Iraqi | 2018 | Animal Models and Experimental Medicine2018,1,3: | 3 |
| 16 | A new age in understanding adult hippocampal neurogenesis in Alzheimer’s disease显示文摘Several lines of evidence have established that proliferation and differentiation of neural stem cells into neurons within the sub-granular zone of the dentate gyrus,a process named adult hippocampal neurogenesis,contribute to maintaining healthy cognitive functions throughout life.The rate of adult hippocampal neurogenesis decreases with aging and a premature impairment of adult hippocampal neurogenesis has been observed both in animal models of Alzheimer’s disease and human post-mortem tissues.The causal relationship between adult hippocampal neurogenesis and the development of Alzheimer’s disease pathology has,however,not been established.This is partly due to the limitation of recapitulating the development of Alzheimer’s disease pathology in rodent models and the lack of translatable biomarkers to identify tractable targets in humans.While it is tempting to postulate that adult hippocampal neurogenesis could be leveraged to improve cognitive deficits in Alzheimer’s disease,consensual results have yet to be reached to fully explore this hypothesis.In this review,we discuss how the recent progress in identifying molecular pathways in adult hippocampal neurogenesis provides a good framework to initiate strategies for drug-based intervention in neurodegenerative diseases,especially in Alzheimer’s disease.We outline how discrepancies in pre-clinical disease models and experimental methodology have resulted in contradictory findings and propose a shift towards using more translatable approaches to model neurogenesis in Alzheimer’s disease.In particular,we review how exploring novel experimental paradigms including the use of human induced pluripotent stem cells and more complex cell culture systems,as well as standardizing protocols used to investigate evidence of neurogenesis in human tissues,could deliver deeper mechanistic insights that would kick-start innovative drug discovery efforts to promote healthy aging and cellular rejuvenation. | Maya A.Hanspal Sébastien Gillotin | 2022 | Neural Regeneration Research2022,17,12: | 3 |
