3Lower Bifidobacteria counts in both duodenal mucosa-associated and fecal microbiota in irritable bowel syndrome patients显示文摘AIM: To determine the composition of both fecal and duodenal mucosa-associated microbiota in irritable bowel syndrome (IBS) patients and healthy subjects using molecular-based techniques. METHODS: Fecal and duodenal mucosa brush samples were obtained from 41 IBS patients and 26 healthy subjects. Fecal samples were analyzed for the composition of the total microbiota using fluorescent in situ hybridization (FISH) and both fecal and duodenal brush samples were analyzed for the composition of bif idobacteria using real-time polymerase chain reaction. RESULTS: The FISH analysis of fecal samples revealed a 2-fold decrease in the level of bifidobacteria (4.2 ± 1.3 vs 8.3 ± 1.9, P < 0.01) in IBS patients compared to healthy subjects, whereas no major differences in other bacterial groups were observed. At the species level, Bifidobacterium catenulatum levels were significantly lower (6 ± 0.6 vs 19 ± 2.5, P < 0.001) in the IBS patients in both fecal and duodenal brush samples than in healthy subjects.CONCLUSION: Decreased bifidobacteria levels in both fecal and duodenal brush samples of IBS patients compared to healthy subjects indicate a role for microbiotic composition in IBS pathophysiology.Angèle PM Kerckhoffs Melvin Samsom Michel E van der Rest Joris de Vogel Jan Knol Kaouther Ben-Amor Louis MA Akkermans 2009World Journal of Gastroenterology2009,15,23:33
4Necrotizing enterocolitis: A multifactorial disease with no cure显示文摘Necrotizing enterocolitis is an inflammatory bowel disease of neonates with significant morbidity and mortality in preterm infants. Due to the multifactorial nature o the disease and limitations in disease models, early diagnosis remains challenging and the pathogenesis elusive. Although preterm birth, hypoxic-ischemic events formula feeding, and abnormal bacteria colonization are established risk factors, the role of genetics and vasoactive/inflammatory mediators is unclear Consequently, treatments do not target the specific underlying disease processes and are symptomatic and surgically invasive. Breast-feeding is the most effective preventative measure. Recent advances in the prevention of necrotizing enterocolitis have focused on bioactive nutrients and trophic factors in human milk. Developmen of new disease models including the aspect of prematurity that consistently predisposes neonates to the disease with multiple risk factors will improve our understanding of the pathogenesis and lead to discovery of innovative therapeutics.Kareena L Schnabl John E Van Aerde Alan BR Thomson Michael T Clandinin 2008World Journal of Gastroenterology2008,14,14:19
5Breeding better cultivars,faster:applications of new technologies for the rapid deployment of superior horticultural tree crops显示文摘Woody perennial plants,including trees that produce fruits and nuts of horticultural value,typically have long breeding cycles,and development and introduction of improved cultivars by plant breeders may require many breeding cycles and dozens of years.However,recent advances in biotechnologies and genomics have the potential to accelerate cultivar development greatly in all crops.This mini-review summarizes approaches to reduce the number and the duration of breeding cycles for horticultural tree crops,and outlines the challenges that remain to implement these into efficient breeding pipelines.Steve van Nocker Susan E Gardiner 2014Horticulture Research2014,1,1:19
6Delayed gastric emptying following pancreaticoduodenectomy:Incidence,risk factors,and healthcare utilization显示文摘AIM To characterize incidence and risk factors for delayed gastric emptying(DGE) following pancreaticoduodenectomy and examine its implications on healthcare utilization. METHODS A prospectively-maintained database was reviewed. DGE was classified using International Study Group of Pancreatic Surgery criteria. Patients who developed DGE and those who did not were compared. RESULTS Two hundred and seventy-six patients underwent pancreaticoduodenectomy(PD)(> 80% pyloruspreserving, antecolic-reconstruction). DGE developed in 49 patients(17.8%): 5.1% grade B, 3.6% grade C. Demographic, clinical, and operative variables were similar between patients with DGE and those without. DGE patients were more likely to present multiplecomplications(32.6% vs 4.4%, ≥ 3 complications, P < 0.001), including postoperative pancreatic fistula(POPF)(42.9% vs 18.9%, P = 0.001) and intra-abdominal abscess(IAA)(16.3% vs 4.0%, P = 0.012). Patients with DGE had longer hospital stay(median, 12 d vs 7 d, P < 0.001) and were more likely to require transitional care upon discharge(24.5% vs 6.6%, P < 0.001). On multivariate analysis, predictors for DGE included POPF [OR = 3.39(1.35-8.52), P = 0.009] and IAA [OR = 1.51(1.03-2.22), P = 0.035].CONCLUSION Although DGE occurred in < 20% of patients after PD, it was associated with increased healthcare utilization. Patients with POPF and IAA were at risk for DGE. Anticipating DGE can help individualize care and allocate resources to high-risk patients.Somala Mohammed George Van Buren II Amy Mc Elhany Eric J Silberfein William E Fisher 2017World Journal of Gastrointestinal Surgery2017,9,3:13

8糖尿病膀胱的尿动力学及病理学改变(附动物实验与临床观察)显示文摘目的:观察糖尿病膀胱(DCP)的尿动力学及病理学改变,探讨发病机制及病理演绎过程。方法:建立DCP wistar大鼠模型(30只),正常wistar大鼠作对照(30只),进行膀胱储尿期压、最大容量、最大膀胱压等测定,进行膀胱湿重、膀胱壁厚度及光镜、电镜的病理学观察。早期DCP患者(32例),晚期DCP(28例)及非DM人群(22例)进行尿流率、压力-流率尿道分布压及括约肌肌电图等测定,作相关统计学处理。结果:①60天后,DCP鼠组与对照组:膀胱储尿期压(0.45±0.08)kPa,(0.60±0.03)kPa(P<0.05);最大膀胱容量(3.49±0.40)ml,(1.82±0.12)ml(P<0.01);最大膀胱压(3.09±0.10)kPa,(4.91±0.30)kPa(P<0.01);膀胱顺应性(1.39±0.11)ml.kPa-1,(0.68±0.07)ml.kPa-1(P<0.01);湿重增加(P<0.01);逼尿肌细胞连接纤维化,成纤维细胞变性及胶原纤维排列紊乱。②相对于对照组,早期DCP患者最大尿流率偏低,为(15.97±5.71)ml.s-1(P<0.05),逼尿肌活动亢进(占59%),逼尿肌/括约肌协同失调(占37.5%);而晚期DCP患者最大尿流率明显下降,为(8.75±4.20)ml.s-1(P<0.01),膀胱容量增加,为(472.5±32.9)ml(P<0.01),剩余尿量增多,为(62.59±19.87)ml(P<0.01),逼尿肌收缩功能减弱。结论:DCP早期就有膀胱的动力学及病理学改变,以逼尿肌活动功能亢进,逼尿肌/括约肌协同失调较常见,晚期以逼尿肌收缩功能减弱为主,建议对DCP患者早期就应给予干预,控制病情的进一步恶化。卫中庆 van Koeveringe G A 田成功 王昱 于洪波 易超然 孙则禹 陈炜 van Kerrebroeck P E 2005临床泌尿外科杂志2005,20,11:11
9Schistosoma 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 2010World Journal of Gastroenterology2010,16,6:11
10Clinical outcomes of self-expandable stent placement for benign esophageal diseases: A pooled analysis of the literature显示文摘AIM: To analyze the outcomes of self-expandable stent placement for benign esophageal strictures and benign esophageal leaks in the literature.METHODS: The Pub Med, Embase and Cochrane databases were searched for relevant articles published between January 2000 and July 2014. Eight prospective studies were identified that analyzed the outcomes of stent placement for refractory benign esophageal strictures. The outcomes of stent placement for benign esophageal leaks, perforations and fistulae were extracted from 20 retrospective studies that were published after the inclusion period of a recent systematic review. Data were pooled and analyzed using descriptive statistics.RESULTS: Fully covered self-expandable metal stents(FC SEMS)(n = 85), biodegradable(BD) stents(n = 77) and self-expandable plastic stents(SEPS)(n = 70) were inserted in 232 patients with refractory benign esophageal strictures. The overall clinical success rate was 24.2% and according to stent type 14.1% for FC SEMS, 32.9% for BD stents and 27.1% for SEPS. Stent migration occurred in 24.6% of cases. The overall complication rate was 31.0%, including major(17.7%) and minor(13.4%) complications. A total of 643 patients were treated with self-expandable stents mainly for postsurgical leaks(64.5%), iatrogenic perforations(19.6%), Boerhaave's syndrome(7.8%) and fistulae(3.7%). FC SEMS and partially covered SEMS were used in the majority of patients. Successful closure of the defect was achieved in 76.8% of patients and according to etiology in 81.4% for postsurgical leaks, 86.0% for perforations and 64.7% for fistulae. The pooled stent migration rate was 16.5%. Stent-related complications occurred in 13.4% of patients, including major(7.8%) and minor(5.5%) complications.CONCLUSION: The outcomes of stent placement for refractory benign esophageal strictures were poor. However, randomized trials are needed to put this into perspective. The evidence on successful stent placement for benign esophageal leaks, perforationsand fistulae is promising.Emo E van Halsema Jeanin E van Hooft 2015World Journal of Gastrointestinal Endoscopy2015,7,2:10
11Pancreatic cancer: Advances in treatment显示文摘Pancreatic cancer is a leading cause of cancer mortality and the incidence of this disease is expected to continue increasing.While patients with pancreatic cancer have traditionally faced a dismal prognosis,over the past several years various advances in diagnosis and treatment have begun to positively impact this disease.Identification of effective combinations of existing chemotherapeutic agents,such as the FOLFIRINOX and the gemcitabine+nab-paclitaxel regimen,has improved survival for selected patients although concerns regarding their toxicity profiles remain.A better understanding of pancreatic carcinogenesis has identified several pre-malignant precursor lesions,such as pancreatic intraepithelial neoplasias,intraductal papillary mucinous neoplasms,and cystic neoplasms.Imaging technology has also evolved dramatically so as to allow early detection of these lesions and thereby facilitate earlier management.Surgery remains a cornerstone of treatment for patients with resectable pancreatic tumors,and advances in surgical technique have allowed patients to undergo resection with decreasing perioperative morbidity and mortality.Surgery has also become feasible in selected patients with borderline resectable tumors as a result of neoadjuvant therapy.Furthermore,pancreatectomy involving vascular reconstruction and pancreatectomy with minimally invasive techniques have demonstrated safety without significantly compromising oncologic outcomes.Lastly,a deeper understanding of molecular aberrations contributing to the development of pancreatic cancer shows promise for future development of more targeted and safe therapeutic agents.Somala Mohammed George Van Buren Ⅱ William E Fisher 2014World Journal of Gastroenterology2014,20,28:8

13Pancreatic endometrial cyst mimics mucinous cystic neoplasm of the pancreas显示文摘Pancreatic cysts include a variety of benign, premalignant, and malignant lesions. Endometrial cysts in the pancreas are exceedingly rare lesions that are difficult to diagnose pre-operatively. This report describes the findings in a 43-year-old patient with a recent episode of acute pancreatitis who presented with a large cyst in the tail of the pancreas. Imaging demonstrated a loculated pancreatic cyst, and cyst fluid aspiration revealed an elevated amylase and carcinoembryonic antigen. The patient experienced an interval worsening of abdominal pain, fatigue, diarrhea, and a 15-pound weight loss 3 mo after the initial episode of pancreatitis. With concern for a possible pre-malignant lesion, the patient underwent a laparoscopic distal pancreatectomy with splenectomy, which revealed a 16cm×12cm×4cm lesion. Final histopathology was consistent with an intra-pancreatic endometrial cyst. Here we discuss the overlapping imaging and laboratory features of pancreatic endometrial cysts and mucinous cystic neoplasms of the pancreas.Michael A Mederos Nicole Villafane Sadhna Dhingra Carlos Farinas Amy Mc Elhany William E Fisher George Van Buren II 2017World Journal of Gastroenterology2017,23,6:7
14Endoscopic ultrasonography-guided fine needle aspiration:Relatively low sensitivity in the endosonographer population显示文摘AIM:To assess the characteristics and quality of endoscopic ultrasonography-guided fine needle aspiration(EUS-FNA) in a large panel of endosonographers.METHODS:A survey was conducted during the 13th annual live course of endoscopic ultrasonography(EUS) held in Amsterdam,Netherlands.A 2-page questionnaire was developed for the study.Content validity of the questionnaire was determined based on input by experts in the field and a review of the relevant literature.It contained 30 questions that pertained to demographics and the current practice for EUS-FNA of responders,including sampling technique,sample processing,cytopathological diagnosis and sensitivity of EUS-FNA for the diagnosis of solid mass lesions.One hundred and sixty-one endosonographers who attended the course were asked to answer the survey.This allowed assessing the current practice of EUS-FNA as well as the self-reported sensitivity of EUS-FNA for the diagnosis of solid mass lesions.We also examined which factors were associated with a self-reported sensitivity of EUS-FNA for the diagnosis of solid mass lesions > 80%.RESULTS:Completed surveys were collected from 92(57.1%) of 161 endosonographers who attended the conference.The endosonographers had been practicing endoscopy and EUS for 12.5 ± 7.8 years and 4.8 ± 4.1 years,respectively;one third of them worked in a hospital with an annual caseload > 100 EUS-FNA.Endoscopy practices were located in 29 countries,including 13 countries in Western Europe that totaled 75.3% of the responses.Only one third of endosonographers reported a sensitivity for the diagnosis of solid mass lesions > 80%(interquartile range of sensitivities,25.0%-75.0%).Factors independently associated with a sensitivity > 80% were(1) > 7 needle passes for pancreatic lesions or rapid on-site cytopathological evaluation(ROSE)(P < 0.0001),(2) a high annual hospital caseload(P = 0.024) and(3) routine isolation of microcores from EUS-FNA samples(P = 0.042).ROSE was routinely available to 27.9% of respondents.For lymph nodes and pancreatic masses,a maximum of three needle passes was performed by approximately two thirds of those who did not have ROSE.Microcores were routinely harvested from EUS-FNA samples by approximately one third(37.2%) of survey respondents.CONCLUSION:EUS-FNA sensitivity was considerably lower than reported in the literature.Low EUS-FNA sensitivity was associated with unavailability of ROSE,few needle passes,absence of microcore isolation and low hospital caseload.Jean-Marc Dumonceau Thibaud Koessler Jeanin E van Hooft Paul Fockens 2012World Journal of Gastroenterology2012,18,19:7
15Systematic review: The placebo effect of psychological interventions in the treatment of irritable bowel syndrome显示文摘AIM To determine the placebo response rate associated with different types of placebo interventions used in psychological intervention studies for irritable bowel syndrome. METHODS Randomized controlled trials comparing psychological interventions(stress management/relaxation therapy(cognitive) behavioral therapy, short-term psychodynamic therapy, and hypnotherapy) for the treatment of adult patients with irritable bowel syndrome(IBS) diagnosed with the Manning or Rome criteria with an adequate placebo control treatment and reporting data on IBS symptom severity were identified by searching Pub Med, Embase, the Cochrane Library, CINAHL and Psyc INFO databases. Full-text articles that were written in English and published between 1966 and February 2016 in peer-reviewed journals were selected for the present review. Placebo interventions were considered to be adequate if the number of sessions and the amount of time spent with the therapist were the same as in the active treatment. The placebo response rate(PRR) was computed for IBS symptom severity(primary outcome measure) as well as for anxiety, depression and quality of life(secondary outcome measures). RESULTS Six studies, with a total of 555 patients met the inclusion criteria. Four studies used an educational intervention, whereas two studies used a form of supportive therapy as the placebo intervention. The PRR for IBS symptom severity ranged from 25% to 59%, with a pooled mean of 41.4%. The relative PRR for the secondary outcome measures ranged from 0% to 267% for anxiety, 6% to 52% for depression 20% to 125% for quality of life. The PRR associated with pharmacological treatments, treatment with dietary bran and complementary medicine ranged from 37.5% to 47%. Contrary to our expectations, the PRR in studies on psychological interventions was comparable to that in studies on pharmacological, dietary and alternative medical interventions.CONCLUSION The PRR is probably determined to a larger extent by patient-related factors, such as expectations and desire for the treatment to be effective, than the content of the placebo intervention.Carla E Flik Laura Bakker Wijnand Laan Yanda R van Rood André JPM Smout Niek J de Wit 2017World Journal of Gastroenterology2017,23,12:7
16How to Make Capsules Containing Rejuvenators for Their Use in Asphalt Concrete显示文摘Rejuvenators are products designed to restore original properties to oxidized asphalt binders by restoring the original ratio of asphaltenes to maltenes. But,for a rejuvenator to be successful,it must penetrate the pavement surface. Besides,application of a rejuvenator will also reduce the skid resistance of the pavement. To solve this,these rejuvenators can be encapsulated and mixed in asphalt concrete. Once the stress in the capsules reaches a certain threshold,the particles break and the rejuvenator is released,giving back the original properties of the pavement. The objective of this paper is to show how these capsules behave and define the most appropriate testing methods to find their effect on asphalt concrete. For this,two different types of rejuvenators will be encapsulated and their effect on the properties of the capsules investigated. Besides,the release mechanisms of the capsules will be unravelled.GARCIA A SCHLANGEN E VAN DE VEN M F C 2010武汉理工大学学报2010,32,17:7
17Selecting suitable solid organ transplant donors: Reducing the risk of donor-transmitted infections显示文摘Selection of the appropriate donor is essential to a successful allograft recipient outcome for solid organ transplantation. Multiple infectious diseases have been transmitted from the donor to the recipient via transplantation. Donor-transmitted infections cause increased morbidity and mortality to the recipient. In recent years, a series of high-profile transmissions of infections have occurred in organ recipients prompt-ing increased attention on the process of improving the selection of an appropriate donor that balances the shortage of needed allografts with an approach that mitigates the risk of donor-transmitted infection to the recipient. Important advances focused on improving donor screening diagnostics, using previously excluded high-risk donors, and individualizing the selection of allografts to recipients based on their prior infection history are serving to increase the donor pool and improve outcomes after transplant. This article serves to review the relevant literature surrounding this topic and to provide a suggested approach to the selection of an appropriate solid organ transplant donor.Christopher S Kovacs Jr Christine E Koval David van Duin Amanda Guedes de Morais Blanca E Gonzalez Robin K Avery Steven D Mawhorter Kyle D Brizendine Eric D Cober Cyndee Miranda Rabin K Shrestha Lucileia Teixeira Sherif B Mossad 2014World Journal of Transplantation2014,4,2:7
18m TOR signaling in liver regeneration: Rapamycin combined with growth factor treatment显示文摘AIM: To investigate the effects of mammalian target of rapamycin(mT OR) inhibition on liver regeneration and autophagy in a surgical resection model.METHODS: C57BL/6 mice were subjected to a 70% partial hepatectomy(PH) and treated intraperitoneally every 24 h with a combination of the m TOR inhibitor rapamycin(2.5 mg/kg per day) and the steroid dexamethasone(2.0 mg/kg per day) in phosphate bufferedsaline(PBS) or with PBS alone as vehicle control. In the immunosuppressant group, part of the group was treated subcutaneously 4 h prior to and 24 h after PH with a combination of human recombinant interleukin 6(IL-6; 500 μg/kg per day) and hepatocyte growth factor(HGF; 100 μg/kg per day) in PBS. Animals were sacrificed 2, 3 or 5 d after PH and liver tissue and blood were collected for further analysis. Immunohistochemical staining for 5-Bromo-2'-deoxyuridine(Brd U) was used to quantify hepatocyte proliferation. Western blotting was used to detect hepatic microtubule-associated protein 1 light chain 3(LC3)-Ⅱ protein expression as a marker for autophagy. Hepatic gene expression levels of proliferation-, inflammation- and angiogenesisrelated genes were examined by real-time reverse transcription-polymerase chain reaction and serum bilirubin and transaminase levels were analyzed at the clinical chemical core facility of the Erasmus MC-University Medical Center.RESULTS: m TOR inhibition significantly suppressed regeneration, shown by decreased hepatocyte proliferation(2% vs 12% Brd U positive hepatocyte nuclei at day 2, P < 0.01; 0.8% vs 1.4% at day 5, P = 0.02) and liver weight reconstitution(63% vs 76% of initial total liver weight at day 3, P = 0.04), and furthermore increased serum transaminase levels(aspartate aminotransferase 641 U/L vs 185 U/L at day 2, P = 0.02). Expression of the autophagy marker LC3-Ⅱ, which was reduced during normal liver regeneration, increased after mT OR inhibition(46% increase at day 2, P = 0.04). Hepatic gene expression showed an increased inflammation-related response [tumor necrosis factor(TNF)-α 3.2-fold upregulation at day 2, P = 0.03; IL-1Ra 6.0-fold upregulation at day 2 and 42.3-fold upregulation at day 5, P < 0.01] and a reduced expression of cell cycle progression and angiogenesis-related factors(HGF 40% reduction at day 2; vascular endothelial growth factor receptor 2 50% reduction at days 2 and 5; angiopoietin 1 60% reduction at day 2, all P ≤ 0.01). Treatmentwith the regeneration stimulating cytokine IL-6 and growth factor HGF could overcome the inhibitory effect on liver weight(75% of initial total liver weight at day 3, P = 0.02 vs immunosuppression alone and P = 0.90 vs controls) and partially reversed gene expression changes caused by rapamycin(TNF-α and IL-1Ra levels at day 2 were restored to control levels). However, no significant changes in hepatocyte proliferation, serum injury markers or autophagy were found.CONCLUSION: mT OR inhibition severely impairs liver regeneration and increases autophagy after PH. These effects are partly reversed by stimulation of the IL-6 and HGF pathways.Suomi MG Fouraschen Petra E de Ruiter Jaap Kwekkeboom Ron WF de Bruin Geert Kazemier Herold J Metselaar Hugo W Tilanus Luc JW van der Laan Jeroen de Jonge 2013World Journal of Transplantation2013,3,3:6
19High-density SNP-based genetic maps for the parents of an outcrossed and a selfed tetraploid garden rose cross, inferred from admixed progeny using the 68k rose SNP array显示文摘Dense genetic maps create a base for QTL analysis of important traits and future implementation of marker-assisted breeding.In tetraploid rose,the existing linkage maps include<300 markers to cover 28 linkage groups(4 homologous sets of 7 chromosomes).Here we used the 68k WagRhSNP Axiom single-nucleotide polymorphism(SNP)array for rose,in combination with SNP dosage calling at the tetraploid level,to genotype offspring from the garden rose cultivar‘Red New Dawn’.The offspring proved to be not from a single bi-parental cross.In rose breeding,crosses with unintended parents occur regularly.We developed a strategy to separate progeny into putative populations,even while one of the parents was unknown,using principle component analysis on pairwise genetic distances based on sets of selected SNP markers that were homozygous,and therefore uninformative for one parent.One of the inferred populations was consistent with self-fertilization of‘Red New Dawn’.Subsequently,linkage maps were generated for a bi-parental and a self-pollinated population with‘Red New Dawn’as the common maternal parent.The densest map,for the selfed parent,had 1929 SNP markers on 25 linkage groups,covering 1765.5 cM at an average marker distance of 0.9 cM.Synteny with the strawberry(Fragaria vesca)genome was extensive.Rose ICM1 corresponded to F.vesca pseudochromosome 7(Fv7),ICM4 to Fv4,ICM5 to Fv3,ICM6 to Fv2 and ICM7 to Fv5.Rose ICM2 corresponded to parts of F.vesca pseudochromosomes 1 and 6,whereas ICM3 is syntenic to the remainder of Fv6.Mirjana Vukosavljev Paul Arens Roeland E Voorrips Wendy P C van't Westende G D Esselink Peter M Bourke Peter Cox W Eric van de Weg Richard G F Visser Chris Maliepaard Marinus J M Smulders 2016Horticulture Research2016,3,1:6
