1Accuracy and responses of genomic selection on key traits in apple breeding显示文摘The application of genomic selection in fruit tree crops is expected to enhance breeding eficiency by increasing prediction accuracy,increasing selection intensity and decreasing generation interval.The objectives of this study were to assess the accuracy of prediction and selection response in commercial apple breeding programmes for key traits.The training population comprised 977 individuals derived from 20 pedigreed fllsib families.Historic phenotypic data were available on 10 traits related to productivity and fruit external appearance and genotypic data for 7829 SNPs obtained with an llumina 20K SNP array.From these data,a genome-wide prediction model was built and subsequently used to calculate genomic breeding values of five application fllsib families.The application families had genotypes at 364 SNPs from a dedicated 512 SNP array,and these genotypic data were extended to the high-density level by imputation.These five families were phenotyped for 1 year and their phenotypes were compared to the predicted breeding values.Accuracy of genomic prediction across the 10 traits reached a maximum value of 0.5 and had a median value of 0.19.The accuracies were strongly affected by the phenotypic distribution and heritability of traits.In the largest family,significant selection response was observed for traits with high heritability and symmetric phenotypic distribution.Traits that showed non-significant response often had reduced and skewed phenotypic variation or low heritability.Among the five application families the accuracies were uncorrelated to the degree of relatedness to the training population.The results underline the potential of genomic prediction to accelerate breeding progress in outbred fruit tree crops that still need to overcome long generation intervals and extensive phenotyping costs.Hélène Muranty Michela Troggio Inès Ben Sadok Mehdi Al Rifaï Annemarie Auwerkerken Elisa Banchi Riccardo Velasco Piergiorgio Stevanato W.Eric van de Weg Mario Di Guardo Satish Kumar François Laurens Marco C.A.M.Bink 2015Horticulture Research2015,2,1:14
2国际糖尿病足工作组:糖尿病足溃疡分类指南——《国际糖尿病足工作组:糖尿病足防治国际指南(2019)》的一部分显示文摘国际糖尿病足工作组(IWGDF)自1999年以来一直以循证为基础发布糖尿病足病的预防和管理指南。本文中针对日常临床工作中糖尿病足溃疡的分类提出了新指南,并对既有的分类进行了综述。新指南只对现患糖尿病足溃疡进行分类,不包括用于定义未来溃疡风险的分类系统。本指南的制定是基于对现有文献的综述以及专家对最大程度影响临床结局的8个关键因素的鉴定。分类级别是根据关键因素的数量、内部和外部有效性验证以及使用意向而制定的。判定分类评分的关键因素有3种:患者相关的因素(终末期肾衰竭)、肢体相关的因素(周围动脉病变和保护性感觉丧失)和溃疡相关的因素(面积、深度、部位、单发或多发以及感染)。特殊分类系统要考虑以下5种临床情况:①卫生专业人员之间交流;②预测单个溃疡预后;③对个案临床决策的辅助;④伤口评估,有感染或无感染及周围动脉病变(评估灌注及血管重建的潜在益处);⑤用于地方、区域或国家人群结局的稽查。指南推荐:①医务人员之间交流使用SINBAD系统。②无适用于预测个体溃疡预后的分类。③感染的评估采用美国传染病学会/国际糖尿病足工作组(IDSA/IWGDF)分类系统。④评估灌注及血管重建的潜在获益使用创面、缺血、足感染(WIfI)系统。⑤人群结局的稽查使用SINBAD系统。Matilde Monteiro-Soares David Russell Edward J Boyko William Jeffcoate Joseph L Mills Stephan Morbach Fran Game 王爱红(译) 冉兴无(审校) 2019感染.炎症.修复2019,20,4:10
3Quasispecies evolution in NS5A region of hepatitis C virus genotype 1b during interferon or combined interferon-ribavirin therapy显示文摘AIM: To evaluate the implication of substitutions in the hepatitis C virus (HCV) non-structural 5A (NS5A) protein in the resistance of HCV during mono-interferon (IFN) or combined IFN-ribavirin (IFN-R) therapy. Although NS5A has been reported to interact with the HCV RNA- dependent RNA polymerase, NS5B, as well as with many cellular proteins, the function of NS5A in the life cycle of HCV remains unclear. METHODS: HCV quasispecies were studied by clon- ing and sequencing of sequential isolates from patients infected by HCV genotype 1b. Patients were treated by IFN-α2b for 3 mo followed by IFN-α2b alone or com- bined IFN-R therapy for 9 additional months. Patients were categorized intro two groups based on their re- sponse to the treatments: 7 with sustained virological re- sponse (SVR) (quasispecies = 150) and 3 non-respond- ers (NR) to IFN-R (quasispecies = 106). RESULTS: Prior to treatment, SVR patients displayed a lower complexity of quasispecies than NR patients. Most patients had a decrease in the complexity of quasispe- cies during therapy. Analysis of amino acids substitu- tions showed that the degree of the complexity of the interferon sensitivity-determining region (ISDR) and the V3 domain of NS5A protein was able to discriminate thetwo groups of patients. Moreover, SVR patients displayed more variability in the NS5A region than NR patients. CONCLUSION: These results suggest that detailed mo- lecular analysis of the NS5A region may be important for understanding its function in IFN response during HCV 1b infection.Pascal Veillon Christopher Payan Hélène Le Guillou-Guillemette Catherine Gaudy Franoise Lunel 2007World Journal of Gastroenterology2007,13,8:9
4为不确定的未来实施洪水风险管理战略:荷兰,与莱茵河洪水共生存显示文摘无论从经济还是从自然保护角度,冲积平原和三角洲的社会压力都很大。随着经济的发展及大坝增高,由于预期的损失上升和更深的洪水,洪水风险在逐渐增加。全球变化,社会需求变化了,人们的观念也变化了,需要修订长期的洪水风险管理战略。而修订洪水风险管理战略应以柔性战略替代过去以加高大坝为主的刚性战略。柔性战略为主的洪水风险管理就意味着允许洪水临时性大面积泛滥,通过改变土地利用方式减少洪水灾害损失。这样的战略是基于风险管理和'与洪水共生存'的理念提出的,完全替代了过去的灾害控制观念。荷兰三角洲地区是世界人口密度最大区域之一,在这里,灵活的柔性洪水风险管理战略水文功能和'可持续的标准'被详细阐述和评估。Frans Klijn Michaёl vanBuuren Sabine A.M.vanRooij 石秋池 2004AMBIO-人类环境杂志2004,33,3:9
5Hepatitis B virus mutations potentially conferring adefovir/ tenofovir resistance in treatment-naive patients显示文摘Anti-hepatitis B virus(HBV)therapy leads to the emer- gence of mutant viral strains during the treatment of chronic hepatitis B with nucleos(t)ides analogues. The existence of HBV variants with primary antiviral resistance may be important for treatment choice. We studied two patients with chronic HBV infection by sequencing the HBV polymerase gene.They had adefovir-and tenofovir-related mutations in the viral polymerase,although they had never been treated. These mutations were rtV214A/rtN238T in one patient and rtA194T in the other.Thus,mutations in untreated patients deserve cautious surveillance.These data indicate that mutations that can theoretically confer adefovir or tenofovir resistance may emerge in treatmentnaive patients.Rebecca Pastor Franois Habersetzer Samira Fafi-Kremer Michel Doffoёl Thomas F Baumert Jean-Pierre Gut Franoise Stoll-Keller Evelyne Schvoerer 2009World Journal of Gastroenterology2009,15,6:6
6Relationship between Th17 immune response and cancer显示文摘Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades.Cancer has a close relationship with the immune system and,although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity,studies have emphasized their roles in cancer pathogenesis.The Th17 immune response profile is involved in several types of cancer including urogenital,respiratory,gastrointestinal,and skin cancers.This type of immune response exerts pro and antitumor functions through several mechanisms,depending on the context of each tumor,including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment.Among other factors,the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential,which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells.Interleukin(IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment,which allow Th17 cells to prevail in tumors.Moreover,the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers,being associated with variable clinical outcomes.The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets.Hanna Santos Marques Breno Bittencourt de Brito Filipe Antônio França da Silva Maria Luísa Cordeiro Santos Júlio César Braga de Souza Thiago Macêdo Lopes Correia Luana Weber Lopes Nayara Silva de Macêdo Neres Rafael Santos Dantas Miranda Dórea Anna Carolina Saúde Dantas Lorena Lôbo Brito Morbeck Iasmin Souza Lima Amanda Alves de Almeida Maiara Raulina de Jesus Dias Fabrício Freire de Melo 2021World Journal of Clinical Oncology2021,12,10:5
7Selection of patients and staging of peritoneal surface malignancies显示文摘Peritoneal carcinomatosis (PC) is a common evolution of cancer of the gastrointestinal tract, and has been traditionally regarded as a terminal disease with short median survival. During the last 20 years, thanks to its favourable oncologic results, a new loco-regional therapeutic approach, combining cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC), has an important development. Due to its significant, but acceptable, morbidity and mortality, and high cost, this comprehensive management plan requires knowledgeable patient selection. Quantitative prognostic indicators are required to assess a patient’s eligibility. Large multicenter studies have identified several prognostic factors, which can be used for a better selection of patients who would benefit from the combination of cytoreductive surgery with HIPEC. Indications for treatment of PC with cytoreduction and HIPEC are now validated for several diseases: peritoneal mesothelioma, pseudomyxoma peritonei, PC from the appendix, and colorectal cancer. Indications are still under discussion for gastric and ovarian carcinomatosis. Computed tomography is the best radiological for staging the disease. The extent of peritoneal carcinomatosis is, however, difficult to evaluate preoperatively, and precise evaluation is most often performed during surgical exploration. Cytoreductive surgery associated with HIPEC for the treatment of peritoneal carcinomatosis should be performed for young patients with limited and resectable carcino-matosis, in specialized institutions involved in the management of peritoneal surface malignancies.Eddy Cotte Guillaume Passot Franois-Noёl Gilly Olivier Glehen 2010World Journal of Gastrointestinal Oncology2010,2,1:4
8Neutralizing antibodies in hepatitis C virus infection显示文摘Hepatitis C virus (HCV) is a major cause of hepatitis world-wide. The majority of infected individuals develop chronic hepatitis which can then progress to liver cirrhosis and hepatocellular carcinoma. Spontaneous viral clearance occurs in about 20%-30% of acutely infected individuals and results in resolution of infection without sequaelae. Both viral and host factors appear to play an important role for resolution of acute infection. A large body of evidence suggests that a strong, multispecific and long-lasting cellular immune response appears to be important for control of viral infection in acute hepatitis C. Due too the lack of convenient neutralization assays, the impact of neutralizing responses for control of viral infection had been less defined. In recent years, the development of robust tissue culture model systems for HCV entry and infection has finally allowed study of antibody-mediated neutralization and to gain further insights into viral targets of host neutralizing responses. In addition, detailed analysis of antibody-mediated neutralization in individual patients as well as cohorts with well defined viral isolates has enabled the study of neutralizing responses in the course of HCV infection and characterization of the impact of neutralizing antibodiesfor control of viral infection. This review will summarize recent progress in the understanding of the molecular mechanisms of antibody-mediated neutralization and its impact for HCV pathogenesis.Mirjam B Zeisel Samira Fafi-Kremer Isabel Fofana Heidi Barth Franoise Stoll-Keller Michel Doffo■l Thomas F Baumert 2007World Journal of Gastroenterology2007,13,36:3
9A high-density, multi-parental SNP genetic map on apple validates a new mapping approach for outcrossing species显示文摘Quantitative trait loci(QTL)mapping approaches rely on the correct ordering of molecular markers along the chromosomes,which can be obtained from genetic linkage maps or a reference genome sequence.For apple(Malus domestica Borkh),the genome sequence v1 and v2 could not meet this need;therefore,a novel approach was devised to develop a dense genetic linkage map,providing the most reliable marker-loci order for the highest possible number of markers.The approach was based on four strategies:(i)the use of multiple full-sib families,(ii)the reduction of missing information through the use of HaploBlocks and alternative calling procedures for single-nucleotide polymorphism(SNP)markers,(iii)the construction of a single backcross-type data set including all families,and(iv)a two-step map generation procedure based on the sequential inclusion of markers.The map comprises 15417 SNP markers,clustered in 3 K HaploBlock markers spanning 1267 cM,with an average distance between adjacent markers of 0.37 cM and a maximum distance of 3.29 cM.Moreover,chromosome 5 was oriented according to its homoeologous chromosome 10.This map was useful to improve the apple genome sequence,design the Axiom Apple 480 K SNP array and perform multifamily-based QTL studies.Its collinearity with the genome sequences v1 and v3 are reported.To our knowledge,this is the shortest published SNP map in apple,while including the largest number of markers,families and individuals.This result validates our methodology,proving its value for the construction of integrated linkage maps for any outbreeding species.Erica A Di Pierro Luca Gianfranceschi Mario Di Guardo Herma JJ Koehorst-van Putten Johannes W Kruisselbrink Sara Longhi Michela Troggio Luca Bianco Hélène Muranty Giulia Pagliarani Stefano Tartarini Thomas Letschka Lidia Lozano Luis Larisa Garkava-Gustavsson Diego Micheletti Marco CAM Bink Roeland E Voorrips Ebrahimi Aziz Riccardo Velasco François Laurens W Eric van de Weg 2016Horticulture Research2016,3,1:3
