Trasplante de sangre cordón umbilical de donante no emparentado en adultos con enfermedades hematológicas malignas
2013
En los últimos años se ha producido un gran incremento de la actividad de trasplante de sangre de cordón umbilical (TSCU) en adultos. Diferentes estudios han demostrado que el TSCU es viable en pacientes adultos con enfermedades hematológicas malignas y se debe considerar como alternativa a la MO o SP de DNE adulto. Los objetivos de este trabajo de tesis doctoral fueron analizar los resultados terapéuticos de una amplia serie de pacientes adultos con neoplasias hematológicas sometidos a TSCU, así como analizar las variables independientes (explicativas) que pudieran tener un impacto en los resultados mediante métodos de análisis univariante y multivariante. Se analizaron 199 pacientes adult…
Santo Dominguito de Val: La ?tradición? como arma arrojadiza a disposición de los poderes establecidos
2019
This study focuses, from a short story of the blood libel of Saint Dominguito de Val, on answering the questions of when and why the ?tradition? was made about this saint, and the specific moments of his Revitalization until the end of the 17th century. Although the short story of the death of this infant has been occupied by the most diverse writers of the sixteenth and seventeenth centuries, we take as reference the master Espés and the chroniclers Blancas, Andrés de Uztarroz and Dormer.
EPIDEMIOLOGY OF BOUTONNEUSE FEVER IN WESTERN SICILY
1986
The distribution and prevalence of spotted fever group rickettsial infection in the ixodid dog tick Rhipicephalus sanguineus were found to occur at a rate of 19.7% with variation related to geographic and sociooccupational factors. A higher rate of infection was demonstrated in ticks removed from dogs associated with documented cases of boutonneuse fever. The results fit into available clinical and seroepidemiologic data on Rickettsia conorii infection in western Sicily.
Hereditary combined deficiency of the vitamin K-dependent clotting factors
2010
Abstract Hereditary combined vitamin K-dependent clotting factors deficiency (VKCFD) is a rare congenital bleeding disorder resulting from variably decreased levels of coagulation factors II, VII, IX and X as well as natural anticoagulants protein C, protein S and protein Z. The spectrum of bleeding symptoms ranges from mild to severe with onset in the neonatal period in severe cases. The bleeding symptoms are often life-threatening, occur both spontaneously and in a surgical setting, and usually involve the skin and mucosae. A range of non-haemostatic symptoms are often present, including developmental and skeletal anomalies. VKCFD is an autosomal recessive disorder caused by mutations in …
Effect of leaf removal and ripening stage on the content of quercetin glycosides in Sangiovese grapes
2021
Quercetin haze has been observed over the last few years in some aged Sangiovese wines. This problem could be due to an excess of the quercetin in the wine. Leaf removal increases the exposition of clusters to sunlight, which may enhance flavonol synthesis in the grapes. In this study, we evaluated the dynamics related to extractable flavonols in grapes grown in three usually defoliated Vitis vinifera (L.) cv. Sangiovese vineyards, whose wines showed quercetin precipitates. The particular structure of the vineyards in which the leaf removal experiments were carried out allowed the influence of vineyard, biotype and rootstock on grape flavonol contents at mid-maturation and technological mat…

Rôle des antigènes tissulaires de groupes sanguins humains A, B, H et Lewis dans l'évolution des Norovirus GII.4
2011
Noroviruses are one of the leading causes of gastroenteritis worldwide. Since 2002 successive GII.4 variants have circulated in the population before being replaced every 2-3 years, which raises questions about the role of their histo-blood group antigen (HBGAs) receptors in their evolution. We analyzed the interaction between representative GII.4 variants and HBGAs and determined the role of selected amino acids (aa) in the binding profiles. By mutagenesis, we showed that there was a strict structural requirement for the aa directly implicated in HBGA bindings. The ablation of the threonine 395 residue, an epidemiological feature of the post 2002 variants, allowed to gain the capacity to b…
Résistances aux herbicides : les estivales en force !
2015
Contexte - Des cas de moindre efficacité de désherbage à base d’herbicides inhibiteurs de l’ALS ont été signalés en cultures de printemps. Des tests ont été réalisés pour savoir s’il s’agit de résistances et, si oui, dues à quel mécanisme. PSD sur maïs - Cinq populations de graminées estivales (deux de panic pied-de-coq, une de sétaire verte, deux de digitaire sanguine) ont été prélevées dans des parcelles de maïs où le désherbage n’avait pas donné satisfaction. Des plantes résistantes ont été identifiées dans toutes ces populations. Le mécanisme a été identifié. Il s’agit dans tous les cas de RNLC, résistance non liée à la cible. Ambroisie - Une dizaine de populations d’ambroisie à feuille…
