1Contrast-enhanced ultrasound of histologically proven hepatic epithelioid hemangioendothelioma显示文摘AIM: To analyze contrast-enhanced ultrasound(CEUS) features of histologically proven hepatic epithelioid hemangioendothelioma(HEHE) in comparison to other multilocular benign focal liver lesions(FLL).METHODS: Twenty-five patients with histologically proven HEHE and 45 patients with histologically proven multilocular benign FLL were retrospectively reviewed. Four radiologists assessed the CEUS enhancement pattern in consensus.RESULTS: HEHE manifested as a single(n = 3) or multinodular(n = 22) FLL. On CEUS, HEHE showed rim-like(18/25, 72%) or heterogeneous hyperenhancement(7/25, 28%) in the arterial phase and hypoenhancement(25/25, 100%) in the portal venous and late phases(PVLP), a sign of malignancy. Eighteen patients showed central unenhanced areas(18/25, 72%); in seven patients(7/25, 28%), more lesions were detected in the PVLP. In contrast, all patients with hemangioma and focal nodular hyperplasia showed hyperenhancement as the most distinctive feature(P < 0.01).CONCLUSION: CEUS allows for characterization of unequivocal FLL. By analyzing the hypoenhancement in the PVLP, CEUS can determine the malignant nature of HEHE.Yi Dong Wen-Ping Wang Vito Cantisani Mirko D'Onofrio Andre Ignee Lorenzo Mulazzani Adrian Saftoiu Zeno Sparchez Ioan Sporea Christoph F Dietrich 2016World Journal of Gastroenterology2016,22,19:21
2Genome resequencing and transcriptome profiling reveal structural diversity and expression patterns of constitutive disease resistance genes in Huanglongbing-tolerant Poncirus trifoliata and its hybrids显示文摘Huanglongbing(HLB)is the most destructive bacterial disease of citrus worldwide.While most citrus varieties are susceptible to HLB,Poncirus trifoliata,a close relative of Citrus,and some of its hybrids with Citrus are tolerant to HLB.No specific HLB tolerance genes have been identified in P.trifoliata but recent studies have shown that constitutive disease resistance(CDR)genes were expressed at much higher levels in HLB-tolerant Poncirus hybrids and the expression of CDR genes was modulated by Candidatus Liberibacter asiaticus(CLas),the pathogen of HLB.The current study was undertaken to mine and characterize the CDR gene family in Citrus and Poncirus and to understand its association with HLB tolerance in Poncirus.We identified 17 CDR genes in two citrus genomes,deduced their structures,and investigated their phylogenetic relationships.We revealed that the expansion of the CDR family in Citrus seems to be due to segmental and tandem duplication events.Through genome resequencing and transcriptome sequencing,we identified eight CDR genes in the Poncirus genome(PtCDR1-PtCDR8).The number of SNPs was the highest in PtCDR2 and the lowest in PtCDR7.Most of the deletion and insertion events were observed in the UTR regions of Citrus and Poncirus CDR genes.PtCDR2 and PtCDR8 were in abundance in the leaf transcriptomes of two HLB-tolerant Poncirus genotypes and were also upregulated in HLB-tolerant,Poncirus hybrids as revealed by real-time PCR analysis.These two CDR genes seem to be good candidate genes for future studies of their role in citrus-CLas interactions.Nidhi Rawat Brajendra Kumar Ute Albrecht Dongliang Du Ming Huang Qibin Yu Yi Zhang Yong-Ping Duan Kim D Bowman Fred G Gmitter Jr Zhanao Deng 2017Horticulture Research2017,4,1:5

4Serous pancreatic neoplasia, data and review显示文摘AIM To describe the imaging features of serous neoplasms of the pancreas using ultrasound, endoscopic ultrasound, computed tomography and magnetic resonance imaging.METHODS This multicenter international collaboration enhances a literature review to date, reporting features of 287 histologically confirmed cases of serous pancreatic cystic neoplasms(SPN). RESULTS Female predominance is seen with most SPN presenting asymptomatically in the 5th through 7th decade. Mean lesion size was 38.7 mm, 98% were single, 44.2% cystic, 46% mixed cystic and solid, and 94% hypoechoic on B-mode ultrasound. Vascular patterns and contrast-enhancement profiles are described as hypervascular and hyperenhancing.CONCLUSION The described ultrasound features can aid differentiation of SPN from other neoplastic lesions under most circumstances.Christoph F Dietrich Yi Dong Christian Jenssen Valentina Ciaravino Michael Hocke Wen-Ping Wang Eike Burmester Kathleen Moeller Nathan SS Atkinson Paola Capelli Mirko D’Onofrio 2017World Journal of Gastroenterology2017,23,30:3

6One stop shop IV: taxonomic update with molecular phylogeny for important phytopathogenic genera: 76-100 (2020)显示文摘This is a continuation of a series focused on providing a stable platform for the taxonomy of phytopathogenic fungi and fungus-like organisms.This paper focuses on one family:Erysiphaceae and 24 phytopathogenic genera:Armillaria,Barrio-psis,Cercospora,Cladosporium,Clinoconidium,Colletotrichum,Cylindrocladiella,Dothidotthia,,Fomitopsis,Ganoderma,Golovinomyces,Heterobasidium,Meliola,Mucor,Neoerysiphe,Nothophoma,Phellinus,Phytophthora,Pseudoseptoria,Pythium,Rhizopus,Stemphylium,Thyrostroma and Wojnowiciella.Each genus is provided with a taxonomic background,distribution,hosts,disease symptoms,and updated backbone trees.Species confirmed with pathogenicity studies are denoted when data are available.Six of the genera are updated from previous entries as many new species have been described.Ruvishika S.Jayawardena Kevin D.Hyde Yi Jyun Chen Viktor Papp Balázs Palla Dávid Papp Chitrabhanu S.Bhunjun Vedprakash G.Hurdeal Chanokned Senwanna Ishara S.Manawasinghe Dulanjalee L.Harischandra Ajay Kumar Gautam Shubhi Avasthi Boontiya Chuankid Ishani D.Goonasekara Sinang Hongsanan XiangYu Zeng Kapila K.Liyanage NingGuo Liu Anuruddha Karunarathna Kalani K.Hapuarachchi Thatsanee Luangharn Olivier Raspé Rashika Brahmanage Mingkwan Doilom Hyang B.Lee Liu Mei Rajesh Jeewon Naruemon Huanraluek Napalai Chaiwan Marc Stadler Yong Wang 2020Fungal Diversity2020,,4:2
