1Parvovirus B19 induced hepatic failure in an adult requiring liver transplantation显示文摘Parvovirus B19 induced acute hepatitis and hepatic failure have been previously reported, mainly in children. Very few cases of parvovirus induced hepatic failure have been reported in adults and fewer still have required liver transplantation. We report the case of a 55-year-old immunocompetent woman who developed fulminant hepatic failure after acute infection with Parvovirus B19 who subsequently underwent orthotopic liver transplantation. This is believed to be the first reported case in the literature in which an adult patient with fulminant hepatic failure associated with acute parvovirus B19 infection and without hematologic abnormalities has been identified prior to undergoing liver transplantation. This case suggests that Parvovirus B19 induced liver disease can affect adults, can occur in the absence of hematologic abnormalities and can be severe enough to require liver transplantation.Darin S Krygier Urs P Steinbrecher Martin Petric Siegfried R Erb Stephen W Chung Charles H Scudamore Andrzej K Buczkowski Eric M Yoshida 2009World Journal of Gastroenterology2009,15,32:3
2Landscape features and weather influence nest survival of a ground-nesting bird of conservation concern,the greater sage-grouse,in humanaltered environments显示文摘Introduction:Ground-nesting birds experience high levels of nest predation.However,birds can make selection decisions related to nest site location and characteristics that may result in physical,visual,and olfactory impediments to predators.Methods:We studied daily survival rate[DSR]of greater sage-grouse(Centrocercus urophasianus)from 2008 to 2010 in an area in Wyoming experiencing large-scale alterations to the landscape.We used generalized linear mixed models to model fixed and random effects,and a correlation within nesting attempts,individual birds,and years.Results:Predation of the nest was the most common source of nest failure(84.7%)followed by direct predation of the female(13.6%).Generally,landscape variables at the nest site(≤30 m)were more influential on DSR of nests than features at larger spatial scales.Percentage of shrub canopy cover at the nest site(15-m scale)and distances to natural gas wells and mesic areas had a positive relationship with DSR of nests,whereas distance to roads had a negative relationship with DSR of nests.When added to the vegetation model,maximum wind speed on the day of nest failure and a 1-day lag in precipitation(i.e.,precipitation the day before failure)improved model fit whereby both variables negatively influenced DSR of nests.Conclusions:Nest site characteristics that reduce visibility(i.e.,shrub canopy cover)have the potential to reduce depredation,whereas anthropogenic(i.e.,distance to wells)and mesic landscape features appear to facilitate depredation.Last,predators may be more efficient at locating nests under certain weather conditions(i.e.,high winds and moisture).Stephen L Webb Chad V Olson Matthew R Dzialak Seth M Harju Jeffrey B Winstead Dusty Lockman 2012Ecological Processes2012,1,1:2
3Stability of fruit quality traits in diverse watermelon cultivars tested in multiple environments显示文摘Lycopene is a naturally occurring red carotenoid compound that is found in watermelon.Lycopene has antioxidant properties.Lycopene content,sugar content and hollowheart resistance are subject to significant genotype×environment interaction(G×E),which makes breeding for these fruit quality traits difficult.The objectives of this study were to(i)evaluate the influence of years and locations on lycopene content,sugar content and hollowheart resistance for a set of watermelon genotypes,and(ii)identify genotypes with high stability for lycopene,sugar,and hollowheart resistance.A diverse set of 40 genotypes was tested over 3 years and 8 locations across the southern United States in replicated,multi-harvest trials.Lycopene was tested in a subset of 10 genotypes.Data were analyzed using univariate and multivariate stability statistics(BLUP-GGE biplot)using SASGxE and RGxE programs.There were strong effects of environment as well as G×E interaction on watermelon quality traits.On the basis of stability measures,genotypes were classified as stable or unstable for each quality trait.'Crimson Sweet'is an inbred line with high quality trait performance as well as trait stability.'Stone Mountain','Tom Watson','Crimson Sweet'and'Minilee'were among the best genotypes for lycopene content,sugar content and hollowheart resistance.We developed a stability chart based on marketable yield and average ranking generated from different stability measures for yield attributes and quality traits.The chart will assist in choosing parents for improvement of watermelon cultivars.See http://gffzz783b6e01a04243c3huqbp590pofv56owc.ffgz.tsg.suse.edu.cn/cucurbit/wmelon/wmelonmain.html.Mahendra Dia Todd C Wehner Penelope Perkins-Veazie Richard Hassell Daniel S Price George E Boyhan Stephen M Olson Stephen R King Angela R Davis Gregory E Tolla Jerome Bernier Benito Juarez 2016Horticulture Research2016,3,1:2
