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

3Dietary and metabolomic determinants of relapse in ulcerative colitis patients: A pilot prospective cohort study显示文摘AIM To identify demographic, clinical, metabolomic, and lifestyle related predictors of relapse in adult ulcerative colitis(UC) patients.METHODS In this prospective pilot study, UC patients in clinical remission were recruited and followed-up at 12 mo to assess a clinical relapse, or not. At baseline information on demographic and clinical parameters was collected. Serum and urine samples were collected for analysis of metabolomic assays using a combined direct infusion/liquid chromatography tandem mass spectrometry and nuclear magnetic resolution spectroscopy. Stool samples were also collected to measure fecal calprotectin(FCP). Dietary assessment was performed using a validated self-administered food frequency questionnaire. RESULTS Twenty patients were included(mean age: 42.7 ± 14.8 years, females: 55%). Seven patients(35%) experienced a clinical relapse during the follow-up period. While 6 patients(66.7%) with normal body weight developed a clinical relapse, 1 UC patient(9.1%) who was overweight/obese relapsed during the follow-up(P = 0.02). At baseline, poultry intake was significantly higher in patients who were still in remission during follow-up(0.9 oz vs 0.2 oz, P = 0.002). Five patients(71.4%) with FCP > 150 μg/g and 2 patients(15.4%) with normal FCP(≤ 150 μg/g) at baseline relapsed during the follow-up(P = 0.02). Interestingly, baseline urinary and serum metabolomic profiling of UC patients with or without clinical relapse within 12 mo showed a significant difference. The most important metabolites that were responsible for this discrimination were trans-aconitate, cystine and acetamide in urine, and 3-hydroxybutyrate, acetoacetate and acetone in serum. CONCLUSION A combination of baseline dietary intake, fecal calprotectin, and metabolomic factors are associated with risk of UC clinical relapse within 12 mo.Ammar Hassanzadeh Keshtel iFloris F van den Brand Karen L Madsen Rupasri Mandal Rosica ValchevaKaren I Kroeker Beomsoo Han Rhonda C Bell Janis Cole Thomas Hoevers David S Wishart Richard N Fedorak Levinus A Dieleman 2017World Journal of Gastroenterology2017,23,21:9

9Psychosocial mechanisms for the transmission of somatic symptoms from parents to children显示文摘AIM: To examine familial aggregation of irritable bowel syndrome(IBS) via parental reinforcement/modeling of symptoms, coping, psychological distress, and exposure to stress.METHODS:Mothers of children between the ages of8 and 15 years with and without IBS were identified through the Group Health Cooperative of Puget Sound.Mothers completed questionnaires,including the Child Behavior Checklist(child psychological distress),the Family Inventory of Life Events(family exposure to stress),SCL-90R(mother psychological distress),and the Pain Response Inventory(beliefs about pain).Children were interviewed separately from their parents and completed the Pain Beliefs Questionnaire(beliefs about pain),Pain Response Inventory(coping)and Child Symptom Checklist[gastrointestinal(GI)symptoms].In addition,health care utilization data was obtained from the automated database of Group Health Cooperative.Mothers with IBS(n=207)and their 296 children were compared to 240 control mothers and their 335 children,while controlling for age and education.RESULTS:Hypothesis 1:reinforcement of expression of GI problems is only related to GI symptoms,but not others(cold symptoms)in children.There was no significant correlation between parental reinforcement of symptoms and child expression of GI or other symptoms.Hypothesis 2:modeling of GI symptomsis related to GI but not non-GI symptom reporting in children.Children of parents with IBS reported more non-GI(8.97 vs 6.70,P<0.01)as well as more GI(3.24 vs 2.27,P<0.01)symptoms.Total health care visits made by the mother correlated with visits made by the child(rho=0.35,P<0.001 for cases,rho=0.26,P<0.001 for controls).Hypothesis 3:children learn to share the methods of coping with illness that their mothers exhibit.Methods used by children to cope with stomachaches differed from methods used by their mothers.Only 2/16 scales showed weak but significant correlations(stoicism rho=0.13,P<0.05;acceptance rho=0.13,P<0.05).Hypothesis 4:mothers and children share psychological traits such as anxiety,depression,and somatization.Child psychological distress correlated with mother’s psychological distress(rho=0.41,P<0.001 for cases,rho=0.38,P<0.001 for controls).Hypothesis 5:stress that affects the whole family might explain the similarities between mothers and their children.Family exposure to stress was not a significant predictor of children’s symptom reports.Hypothesis 6:the intergenerational transmission of GI illness behavior may be due to multiple mechanisms.Regression analysis identified multiple independent predictors of the child’s GI complaints,which were similar to the predictors of the child’s non-GI symptoms(mother’s IBS status,child psychological symptoms,child catastrophizing,and child age).CONCLUSION:Multiple factors influence the reporting of children’s gastrointestinal and non-gastrointestinal symptoms.The clustering of illness within families is best understood using a model that incorporates all these factors.Miranda AL van Tilburg Rona L Levy Lynn S Walker Michael Von Korff Lauren D Feld Michelle Garner Andrew D Feld William E Whitehead 2015World Journal of Gastroenterology2015,21,18:2
