Systematic analysis of specific and nonspecific auxin effects on endocytosis and trafficking.
2021
Abstract The phytohormone auxin and its directional transport through tissues are intensively studied. However, a mechanistic understanding of auxin-mediated feedback on endocytosis and polar distribution of PIN auxin transporters remains limited due to contradictory observations and interpretations. Here, we used state-of-the-art methods to reexamine the auxin effects on PIN endocytic trafficking. We used high auxin concentrations or longer treatments versus lower concentrations and shorter treatments of natural indole-3-acetic acid (IAA) and synthetic naphthalene acetic acid (NAA) auxins to distinguish between specific and nonspecific effects. Longer treatments of both auxins interfere wi…
Long-term mineral fertiliser use and maize residue incorporation do not compensate for carbon and nutrient losses from a Ferralsol under continuous m…
2015
9 pages; International audience; It has been repeatedly argued that mineral fertiliser application combined with in situ retention of crop residue biomass can sustain long-term productivity of West African soils. Using 20-year experimental data from southern Togo, a biannual rainfall area, we analysed the effect of two rates of mineral NPK fertiliser application to maize–cotton rotation on the long-term dynamics of soil C and nutrient contents, as compared with two control treatments. Mineral fertiliser treatments consisted of application to both maize (first season) and cotton (second season) the research-recommended NPK rates (Fertiliser-RR) and 1.5 times these rates (Fertiliser-1.5 RR). …

Ferroterapia en el manejo de la anemia en la enfermedad renal crónica no en diálisis: perspectiva del grupo de anemia de la S.E.N
2021
Resumen: Este trabajo realiza una actualización sobre el manejo del déficit de hierro en pacientes con enfermedad renal crónica (ERC), ya sea con o sin anemia. Se revisan las recomendaciones de las guías para el tratamiento de la ferropenia en la ERC. Además, muestra los nuevos estudios sobre ferroterapia en pacientes con ERC, así como los nuevos conocimientos sobre el déficit férrico y su impacto en los resultados clínicos.La anemia es una complicación frecuente de la ERC y se asocia con una disminución en la calidad de vida de los pacientes, así como un aumento de la morbimortalidad. El déficit de hierro (absoluto o funcional) es frecuente en pacientes con ERC que no reciben diálisis y pu…
Morphometric and kinematic sperm subpopulations in split ejaculates of normozoospermic men
2016
This study was designed to analyze the sperm kinematic and morphometric subpopulations in the different fractions of the ejaculate in normozoospermic men. Ejaculates from eight normozoospermic men were collected by masturbation in three fractions after 3-5 days of sexual abstinence. Analyses of sperm motility by computer-assisted sperm analysis (CASA-Mot), and of sperm morphometry by computer-assisted sperm morphometry analysis (CASA-Morph) using fluorescence were performed. Clustering and discriminant procedures were performed to identify sperm subpopulations in the kinematic and morphometric data obtained. Clustering procedures resulted in the classification of spermatozoa into three kine…
Assessment of genetically modified maize MON 87411 for food and feed uses, import and processing, under Regulation (EC) No 1829/2003 (application EFS…
2018
Maize MON 87411 was developed to confer resistance to corn rootworms (Diabrotica spp.) by the expression of a modified version of the Bacillus thuringiensis cry3Bb1 gene and a DvSnf7 dsRNA expression cassette, and tolerance to glyphosate-containing herbicides by the expression of a CP4 5-enolpyruvylshikimate-3-phosphate synthase (cp4 epsps) gene. The molecular characterisation data and bioinformatics analyses did not identify issues requiring assessment for food and feed safety. No statistically significant differences in the agronomic and phenotypic characteristics tested between maize MON 87411 and its conventional counterpart were identified. The compositional analysis of maize MON 87411…
MiR-144 overexpression as a promising therapeutic strategy to overcome glioblastoma cell invasiveness and resistance to chemotherapy
2019
Abstract Glioblastoma (GB) is the most aggressive and common form of primary brain tumor, characterized by fast proliferation, high invasion, and resistance to current standard treatment. The average survival rate post-diagnosis is only of 14.6 months, despite the aggressive standard post-surgery treatment approaches of radiotherapy concomitant with chemotherapy with temozolomide. Altered cell metabolism has been identified as an emerging cancer hallmark, including in GB, thus offering a new target for cancer therapies. On the other hand, abnormal expression levels of miRNAs, key regulators of multiple molecular pathways, have been correlated with pathological manifestations of cancer, such…
Practical Socioeducational to improve School Coexistence. And Experience in a center of unique educational action(Valencia, Spain
2017
[EN] Currently, problems related with coexistence, indiscipline, school violence and disruptive behavior in schools, make worry professionals, students, families and neighborhood. In this way, society at large and the educational community in particular are claiming over time about teaching solutions to mend this situation. In this paper, framed in a broader research, we present the results of application four educational strategies, in a CAES of Valencia (Spain). That strategies was classroom assembly, the reader patronage, game classroom, and art and Human rights. The project was implemented during 2014-2015 academic year, with 80 boys and girls of 4-11 age old. To check the improvement o…
