Impact of vector dispersal and host-plant fidelity on the dissemination of an emerging plant pathogen

2012

International audience; Dissemination of vector-transmitted pathogens depend on the survival and dispersal of the vector and the vector's ability to transmit the pathogen, while the host range of vector and pathogen determine the breath of transmission possibilities. In this study, we address how the interaction between dispersal and plant fidelities of a pathogen (stolbur phytoplasma tuf-a) and its vector (Hyalesthes obsoletus: Cixiidae) affect the emergence of the pathogen. Using genetic markers, we analysed the geographic origin and range expansion of both organisms in Western Europe and, specifically, whether the pathogen's dissemination in the northern range is caused by resident vecto…

Stomatal deregulation in Plasmopara viticola-infected grapevine leaves.

2007

International audience; In grapevine, the penetration and sporulation of Plasmopara viticola occur via stomata, suggesting functional relationships between guard cells and the pathogen. This assumption was supported by our first observation that grapevine (Vitis vinifera cv. Marselan) cuttings infected by P. viticola wilted more rapidly than healthy ones when submitted to water starvation. • Here, complementary approaches measuring stomatal conductance and infrared thermographic and microscopic observations were used to investigate stomatal opening/closure in response to infection. • In infected leaves, stomata remained open in darkness and during water stress, leading to increased transpir…

The Sulfated Laminarin Triggers a Stress Transcriptome before Priming the SA- and ROS-Dependent Defenses during Grapevine's Induced Resistance agains…

2018

Grapevine (Vitis vinifera) is susceptible to many pathogens which cause significant losses to viticulture worldwide. Chemical control is available, but agro-ecological concerns have raised interest in alternative methods, especially in triggering plant immunity by elicitor treatments. The β-glucan laminarin (Lam) and its sulfated derivative (PS3) have been previously demonstrated to induce resistance in grapevine against downy mildew (Plasmopara viticola). However, if Lam elicits classical grapevine defenses such as oxidative burst, pathogenesis-related (PR)-proteins and phytoalexin production, PS3 triggered grapevine resistance via a poorly understood priming phenomenon. The aim of this st…

Method for 3D fibre reconstruction on a microrobotic platform

2015

Automated handling of a natural fibrous object requires a method for acquiring the three-dimensional geometry of the object, because its dimensions cannot be known beforehand. This paper presents a method for calculating the three-dimensional reconstruction of a paper fibre on a microrobotic platform that contains two microscope cameras. The method is based on detecting curvature changes in the fibre centreline, and using them as the corresponding points between the different views of the images. We test the developed method with four fibre samples and compare the results with the references measured with an X-ray microtomography device. We rotate the samples through 16 different orientatio…

Quistes de uraco en adultos. Presentación de 3 casos y revisión de la literatura

2022

Resumen El uraco es un grueso cordon fibroso que aparece a partir del quinto mes de gestacion como consecuencia de la obliteracion de la alantoides. Los quistes de origen uracal se producen como consecuencia de un defecto en la obliteracion de dicho conducto, anomalia que se detecta principalmente en ninos y raramente en adultos. Presentamos 3 casos de quistes uracales en adultos, uno de ellos detectado durante el estudio de dolor abdominal y los otros 2 hallados de forma incidental durante el estudio de otras patologias. En ningun caso se sospecho clinicamente la posibilidad de quistes uracales. Histologicamente, estas lesiones se encuentran revestidas por epitelio de tipo urotelial con ex…

El documento de voluntades anticipadas. Comparativa de la legislación actual en el marco de la Unión Europea

2021

Resumen La Ley 41/2002, de 14 de noviembre, basica reguladora de la autonomia del paciente da valor legal vinculante a las voluntades anticipadas (VA) en Espana. Sin embargo, la situacion en cada pais de la Union Europea es distinta y desconocida para la mayoria del personal sanitario. Para conocer esas diferencias, se realizo una recogida y estudio de las distintas legislaciones en materia de derechos del paciente, y se establecio una comparativa actualizada de las caracteristicas que cada pais otorga a las VA. De los 28 paises de la Union Europea, 15 han desarrollado legislacion especifica en materia de VA, y le otorgan caracter vinculante el 86% si se utiliza la formulacion escrita. Siet…

Una visión integral del cáncer (I). Microambiente tumoral: estudio, clasificación y reprogramación

2019

Resumen El grupo de enfermedades al que nos referimos como «cancer» comparte una estructura biologica conformada por un ecosistema complejo, donde se han alterado las relaciones intercelulares, los campos de informacion, el desarrollo y la funcion tisular. Mas alla de las alteraciones geneticas de la celula tumoral, la demostracion de un ecosistema alterado, con sus interconexiones a nivel sistemico, abre una nueva perspectiva de la biologia y del comportamiento del cancer. Diversas facetas del tumor, su morfologia, clasificacion, agresividad clinica, pronostico y respuesta al tratamiento aparecen ahora bajo una vision integral que ofrece un nuevo horizonte de estudio, investigacion y manej…

Sarcoma fibromixoide de bajo grado, un diagnóstico diferencial esencial en los tumores mixoides de apariencia benigna

2018

Resumen El sarcoma fibromixoide de bajo grado es una neoplasia poco frecuente que afecta preferentemente a adultos jovenes. Se trata de un tumor fibroblastico de apariencia enganosamente benigna que puede presentar recurrencias locales y metastasis a distancia tardias. Presentamos el caso de una nina de 11 anos que presentaba una lesion en el muslo, de la que se realizo exeresis completa. El estudio histologico mostro una neoplasia bien delimitada de estroma mixoide, con celularidad fusiforme sin atipia ni mitosis. La expresion inmunohistoquimica de MUC4, junto con el estudio de biologia molecular que detecto la expresion del gen de fusion FUS-CREB3L2, confirmaron el diagnostico de sarcoma …

Rabdomiosarcoma alveolar. Dos casos negativos para la fusión PAX3-FOXO1 y PAX7-FOXO1

2022

Resumen Los rabdomiosarcomas son los tumores de partes blandas mas frecuentes en la edad pediatrica y en adultos jovenes. Morfologicamente se distinguen dos subtipos principales: el rabdomiosarcoma alveolar y el rabdomiosarcoma embrionario. El subtipo alveolar se asocia generalmente con un peor pronostico y presenta una fusion genica caracteristica que clasicamente se ha utilizado para confirmar el diagnostico: PAX3/7-FOXO1. Presentamos dos casos que fueron remitidos a nuestro centro. Ambos mostraron morfologia alveolar clasica y diferenciacion muscular basada en la inmunohistoquimica; no obstante, carecian de la fusion caracteristica PAX3/7-FOXO1. El objetivo de este articulo es resaltar l…
