| 3 | Microbial markers in colorectal cancer detection and/or prognosis显示文摘Colorectal cancer(CRC) is the second leading cause of cancer worldwide. CRC is still associated with a poor prognosis among patients with advanced disease. On the contrary, due to its slow progression from detectable precancerous lesions, the prognosis for patients with early stages of CRC is encouraging. While most robust methods are invasive and costly, actual patient-friendly screening methods for CRC suffer of lack of sensitivity and specificity. Therefore, the development of sensitive, non-invasive and cost-effective methods for CRC detection and prognosis are necessary for increasing the chances of a cure. Beyond its beneficial functions for the host, increasing evidence suggests that the intestinal microbiota is a key factor associated with carcinogenesis. Many clinical studies have reported a disruption in the gut microbiota balance and an alteration in the faecal metabolome of CRC patients, suggesting the potential use of a microbialbased test as a non-invasive diagnostic and/or prognostic tool for CRC screening. This review aims to discuss the microbial signatures associated with CRC known to date, including dysbiosis and faecal metabolome alterations, andthe potential use of microbial variation markers for noninvasive early diagnosis and/or prognostic assessment of CRC and advanced adenomas. We will finally discuss the possible use of these markers as predicators for treatment response and their limitations. | Romain Villéger Amélie Lopès Julie Veziant Johan Gagnière Nicolas Barnich Elisabeth Billard Delphine Boucher Mathilde Bonnet | 2018 | World Journal of Gastroenterology2018,24,22: | 10 |
| 4 | Type I interferons promote the survival and proinflammatory properties of transitional B cells in systemic lupus erythematosus patients显示文摘A hallmark of systemic lupus erythematosus(SLE)is the breaking of B-cell tolerance with the generation of high-affinity autoantibodies;however,the antibody-independent features of the B-cell compartment in SLE are less understood.In this study,we performed an extensive examination of B-cell subsets and their proinflammatory properties in a Chinese cohort of new-onset SLE patients.We observed that SLE patients exhibited an increased frequency of transitional B cells compared with healthy donors and rheumatoid arthritis patients.Plasma from SLE patients potently promoted the survival of transitional B cells in a type I IFN-dependent manner,which can be recapitulated by direct IFN-αtreatment.Furthermore,the effect of IFN-αon enhanced survival of transitional B cells was associated with NF-κB pathway activation and reduced expression of the pro-apoptotic molecule Bax.Transitional B cells from SLE patients harbored a higher capacity to produce proinflammatory cytokine IL-6,which was also linked to the overactivated type I IFN pathway.In addition,the frequency of IL-6-producing transitional B cells was positively correlated with disease activity in SLE patients,and these cells were significantly reduced after short-term standard therapies.Thus,the current study provides a direct link between type I IFN pathway overactivation and the abnormally high frequency and proinflammatory properties of transitional B cells in active SLE patients,which contributes to the understanding of the roles of type I IFNs and B cells in the pathogenesis of SLE. | Mei Liu Qiang Guo Chunmei Wu Delphine Sterlin Shyamal Goswami Ying Zhang Teng Li Chunde Bao Nan Shen Qiong Fu Xiaoming Zhang | 2019 | Cellular & Molecular Immunology2019,16,4: | 9 |
| 5 | 小麦挥发物对蚜虫及其天敌的行为影响——田间有效挥发性信息化合物的筛选(英文)显示文摘【目的】植物挥发性信息化合物能够影响植食性昆虫及其他天敌行为,因此,在植物-植食性昆虫-天敌互作系统中具有重要地位。目前,小麦[Triticum aestivum L.(Gramineae)]中多种挥发物已被鉴定,为明确其对蚜虫及其天敌的行为影响。【方法】本试验利用四臂嗅觉仪和风洞测定4种不同浓度的小麦挥发物(水杨酸甲酯、3-己酰醋酸酯、己烯醇和1-己醇)对麦长管蚜Sitobion avenae(Fabricus)及其两种重要天敌,异色瓢虫[Harmonia axyridis(Pallas)(Coleoptera:Coccinellidae)]和黑带食蚜蝇[(Episyrphus balteatus(De Geer)(Diptera:Syrphidae)]的行为反应。【结果】结果显示,水杨酸甲酯仅吸引异色瓢虫。3-己酰醋酸酯和己烯醇吸引麦长管蚜及异色瓢虫,但随其浓度增加对蚜虫的吸引作用降低,对异色瓢虫吸引作用增强。3-己酰醋酸酯对黑带食蚜蝇也具有吸引作用。另外,与天敌相比,1-己醇对麦长管蚜吸引作用更强。【结论】总之,本试验明确除1-己醇外,水杨酸甲酯、3-己酰醋酸酯、己烯醇可以作为吸引天敌,控制蚜虫的潜在用于推-拉策略的挥发物性化学信息物。 | 解海翠 Durieux Delphine 范佳 刘勇 Bragard Claude Haubruge Eric 孙京瑞 Francis Frédéric 陈巨莲 | 2014 | 应用昆虫学报2014,51,6: | 8 |

| 7 | New tools for optimizing fluid resuscitation in acute pancreatitis显示文摘Acute pancreatitis(AP)is a frequent disease with degrees of increasing severity responsible for high morbidity.Despite continuous improvement in care,mortality remains significant.Because hypovolemia,together with microcirculatory dysfunction lead to poor outcome,fluid therapy remains a cornerstone of the supportive treatment.However,poor clinical evidence actually support the aggressive fluid therapy recommended in recent guidelines since available data are controversial.Fluid management remains unclear and leads to current heterogeneous practice.Different strategies may help to improve fluid resuscitation in AP.On one hand,integration of fluid therapy in a global hemodynamic resuscitation has been demonstrated to improve outcomein surgical or septic patients.Tailored fluid administration after early identification of patients with high-risk of poor outcome presenting inadequate tissue oxygenation is a major part of this strategy.On the other hand,new decision parameters have been developed recently to improve safety and efficiency of fluid therapy in critically ill patients.In this review,we propose a personalized strategy integrating these new concepts in the early fluid management of AP.This new approach paves the way to a wide range of clinical studies in the field of AP. | Perrine Bortolotti Fabienne Saulnier Delphine Colling Alban Redheuil Sebastien Preau | 2014 | World Journal of Gastroenterology2014,20,43: | 5 |
| 8 | Clinical characteristics and outcomes of patients with hepatic angiomyolipoma:A literature review显示文摘First reported in 1976,hepatic angiomyolipoma(HAML)is a rare mesenchymal liver tumor occurring mostly in middle-aged women.Diagnosis of the liver mass is often incidental on abdominal imaging due to the frequent absence of specific symptoms.Nearly 10%of HAMLs are associated with tuberous sclerosis complex.HAML contains variable proportions of blood vessels,smooth muscle cells and adipose tissue,which renders radiological diagnosis hazardous.Cells express positivity for HMB-45 and actin,thus these tumors are integrated into the group of perivascular epithelioid cell tumors.Typically,a HAML appears on magnetic resonance imaging(or computed tomography scan)as a hypervascular solid tumor with fatty areas and with washout,and can easily be misdiagnosed as other liver tumors,particularly hepatocellular carcinoma.The therapeutic strategy is not clearly defined,but surgical resection is indicated for symptomatic patients,for tumors showing an aggressive pattern(i.e.,changes in size on imaging or high proliferation activity and atypical epithelioid pattern on liver biopsy),for large(>5 cm)biopsy-proven HAML,and if doubts remain on imaging or histology.Conservative management may be justified in other conditions,since most cases follow a benign clinical course.In summary,the correct diagnosis of HAML is challenging on imaging and relies mainly on pathological findings. | Paul Calame Gaelle Tyrode Delphine Weil Verhoeven Sophie Felix Anne Julia Klompenhouwer Vincent Di Martino Eric Delabrousse Thierry Thevenot | 2021 | World Journal of Gastroenterology2021,27,19: | 5 |

| 14 | What neonatal complications should the pediatrician be aware of in case of maternal gestational diabetes?显示文摘In the epidemiologic context of maternal obesity and type 2 diabetes(T2D),the incidence of gestational diabetes has significantly increased in the last decades.Infants of diabetic mothers are prone to various neonatal adverse outcomes,including metabolic and hematologic disorders,respiratory distress,cardiac disorders and neurologic impairment due to perinatal asphyxia and birth traumas,among others.Macrosomia is the most constant consequence of diabetes and its severity is mainly influenced by maternal blood glucose level.Neonatal hypoglycemia is the main metabolic disorder that should be prevented as soon as possible after birth.The severity of macrosomia and the maternal health condition have a strong impact on the frequency and the severity of adverse neonatal outcomes.Pregestational T2 D and maternal obesity significantly increase the risk of perinatal death and birth defects.The high incidence of maternal hyperglycemia in developing countries,associated with the scarcity of maternal and neonatal care,seriously increase the burden of neonatal complications in these countries. | Delphine Mitanchez Catherine Yzydorczyk Umberto Simeoni | 2015 | World Journal of Diabetes2015,6,5: | 4 |

| 18 | Identification of quantitative trait loci and candidate genes for primary metabolite content in strawberry fruit显示文摘Improvement of nutritional and organoleptic quality of fruits is a key goal in current strawberry breeding programs.The ratio of sugars to acids is a determinant factor contributing to fruit liking,although different sugars and acids contribute in varying degrees to this complex trait.A segregating F1 population of 95 individuals,previously characterized for several fruit quality characters,was used to map during 2 years quantitative trait loci(QTL)for 50 primary metabolites,L-ascorbic acid(L-AA)and other related traits such as soluble solid content(SSC),titratable acidity(TA),and pH.A total of 133 mQTL were detected above the established thresholds for 44 traits.Only 12.9%of QTL were detected in the 2 years,suggesting a large environmental influence on primary metabolite content.An objective of this study was the identification of key metabolites that were associated to the overall variation in SSC and acidity.As it was observed in previous studies,a number of QTL controlling several metabolites and traits were co-located in homoeology group V(HG V).mQTL controlling a large variance in raffinose,sucrose,succinic acid,and L-AA were detected in approximate the same chromosomal regions of different homoeologous linkage groups belonging to HG V.Candidate genes for selected mQTL are proposed based on their co-localization,on the predicted function,and their differential gene expression among contrasting F1 progeny lines.RNA-seq analysis from progeny lines contrasting in L-AA content detected 826 differentially expressed genes and identified Mannose-6-phosphate isomerase,FaM6PI1,as a candidate gene contributing to natural variation in ascorbic acid in strawberry fruit. | JoséG.Vallarino Delphine M.Pott Eduardo Cruz-Rus Luis Miranda Juan J.Medina-Minguez Victoriano Valpuesta Alisdair R.Fernie JoséF.Sánchez-Sevilla Sonia Osorio Iraida Amaya | 2019 | Horticulture Research2019,6,1: | 3 |

| 20 | Stability of highly supersaturated vanadium electrolyte solution and characterization of precipitated phases for vanadium redox flow battery显示文摘The vanadium redox flow battery(VRFB)has been receiving great attention in recent years as one of the most viable energy storage technologies for large-scale applications.However,higher concentrations of vanadium species are required in the H_(2)O-H_(2)SO_(4) electrolyte in order to improve the VRFB energy density.This might lead to unwanted precipitation of vanadium compounds,whose nature has not been accurately characterized yet.For this purpose,this study reports the preparation ofⅤ^((Ⅱ)),ⅤV^((Ⅲ)),Ⅴ^((Ⅳ))andⅤ^((Ⅴ))supersaturated solutions in a 5 M H_(2)SO_(4)-H_(2)O electrolyte by an electrolytic method,from the only vanadium sulfate compound commercially available(VOSO_(4)).The precipitates obtained by ageing of the stirred solutions are representative of the solids that may form in a VRFB operated with such supersaturated solutions.The solid phases are identified using thermogravimetric analysis,X-ray diffraction and SEM.We report that dissolvedⅤ^((Ⅱ)),Ⅴ^((Ⅲ))andⅤ^((Ⅳ))species precipitate as crystals of VSO_(4),V_(2)(SO_(4))3 and VOSO_(4) hydrates and not in their anhydrous form;conversely V^((Ⅴ))precipitates as an amorphous V_(2) O_(5) oxide partially hydrated.The measured hydration degrees(respectively 1.5,9,3 and 0.26 mol of H_(2)O per mol of compound)might significantly affect the overall engineering of VRFB operating with high vanadium concentrations. | Waldemir M.Carvalho Jr Laurent Cassayre Delphine Quaranta Fabien Chauvet Ranine El-Hage Theodore Tzedakis Béatrice Biscans | 2021 | Journal of Energy Chemistry2021,30,10: | 3 |
