The Copper-microRNA Pathway Is Integrated with Developmental and Environmental Stress Responses in Arabidopsis thaliana
2021
As an essential nutrient, copper (Cu) scarcity causes a decrease in agricultural production. Cu deficiency responses include the induction of several microRNAs, known as Cu-miRNAs, which are responsible for degrading mRNAs from abundant and dispensable cuproproteins to economize copper when scarce. Cu-miRNAs, such as miR398 and miR408 are conserved, as well as the signal transduction pathway to induce them under Cu deficiency. The Arabidopsis thaliana SQUAMOSA-PROMOTER BINDING PROTEIN-LIKE (SPL) family member SPL7 binds to the cis-regulatory motifs present in the promoter regions of genes expressed under Cu deficiency, including Cu-miRNAs. The expression of several other SPL transcription f…
Progettare la vita di coppia tra lavoro precario e doppia carriera
2014
The study aims to investigate how some transformations in the world of work, such as job insecurity, have repercussions on the couple's life choices. In particular, the paper examines the changes in family projects of couples with "double job insecurity" and "dual career". These couples are often paralyzed by excessive state of uncertainty and/or hard working time, and this weakens their plans for the future. However, having a partner that experiences the same insecurities can help the two members of the couple bear the continuous "family transformations" and improve their equal relationship. The experience of these couples is marked by changes and by the need for coping with various aspect…
Constraining the pass-band of future space-based coronagraphs for observations of solar eruptions in the FeXIV 530.3 nm “green line”
2017
This research has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No 647214) and from the UK Science and Technology Facilities Council. Observations of the solar corona in the FeXIV 530.3 nm “green line” have been very important in the past, and are planned for future coronagraphs on-board forthcoming space missions such as PROBA-3 and Aditya. For these instruments, a very important parameter to be optimized is the spectral width of the band-pass filter to be centred over the “green line”. Focusing on solar eruptions, motions occurring along the line of sight will Doppler shift the line prof…
Determinación de marcas epigenéticas en genesimplicados en la respuesta temprana a Botrytis cinerea de Arabidopsis thaliana y Solanum lycopersicum
2018
Existen en estudios recientes realizados en plantas, evidencias que vinculan la presencia de modificaciones epigenéticas con su respuesta a estreses bióticos. Sin embargo, dentro de estos estreses no se encuentra a penas información sobre patógenos necrótrofos. En esta tesis se exploran las posibles alteraciones en la estructura cromatinica que plantas de las especies Arabidopsis thaliana y Solanum lycopersicum (tomate) podrían experimentar en varios de sus genes expresados en la respuesta a la infección por Botrytis cinerea, un hongo necrótrofo. Se plantea para ellos la puesta a punto de un protocolo de extracción de cromatina y de inmunoprecipitación de la misma (ChIP) y, se relatan las d…
Crystal structure of 3-(tri-phenyl-phosphoranyl-idene)-2,5-di-hydro-furan-2,5-dione tetra-hydro-furan monosolvate.
2018
The title pseudo-polymorph of 3-(triphenylphosphoranylidene)-2,5-dihydrofuran-2,5-dione crystallizes with a tetrahydrofuran solvent molecule, viz. C22H17O3P·C4H8O. The succinic anhydride ring is approximately planar (r.m.s. deviation = 0.032 Å). The tetrahydrofuran molecule is disordered over two orientations about a pseudo-twofold axis with refined occupancy ratio 0.718 (4):0.282 (4). In the crystal, C—H...O hydrogen bonds link molecules of the dihydrofuran-2,5-dione derivative into chains parallel to the b axis and arranged into layers stacked along [100] alternating with hydrogen-bonded tetrahydrofuran layers.
Crystal structures of organoplatinum complexes containing alkyleugenoxyacetate and p-chloroaniline
2016
In the title trans-dichloridoplatinum(II) complexes, the central PtII atom is further coordinated by the p-chloroaniline N atom and ethylenic double bond of alkyleugenoxyacetate.
Tris(1,10-phenanthroline-κ2N,N′)nickel(II) bis(hexafluoridophosphate)
2018
The asymmetric unit of the title compound, [Ni(C36H24N6)3](PF6)2, contains one and a half nickel(II) complex dications and three hexafluoridophosphate anions, one of the dications having crystallographic twofold rotational symmetry. Each NiIIatom displays a distorted octahedral coordination geometry provided by the six N atoms of three bidentate 1,10-phenanthroline ligands with bite angles of 79.68 (11)–80.76 (12)°. In the crystal, C—H...F hydrogen bonds link the anions and dications into a three-dimensional supramolecular framework. Within the framework complex dications with twofold rotational symmetry are linked by weak π–π stacking interactions [centroid-to-centroid distances = 3.712 (2…
Interconfronto di datazione TL ed OSL su terracotta
2010
Nell'ambito di uno specifico programma di datazione tramite luminescenza stimolata termicamente (TL) e otticamente (OSL) campioni di terracotta sono stati preparati e misurati con diverse tecniche allo scopo di minimizzare l'errore sull'età ottenuta. I valori di dose equivalente sono stati ottenuti, su aliquote preparate utilizzando il protocollo standard fine grain (4-11 micron), con la tecnica della doppia Single Aliquot Regeneration AR (d-SAR) nel caso dei segnali OSL. I risultati ottenuti verranno confrontati con le età OSL ottenute di quarzo di granulometria maggiore (90-150 micron).
Cuantificación del daño tisular en tejidos animales fetales tras el uso del Doppler pulsado
2015
El uso de los ultrasonidos (US) en la obstetricia es una herramienta esencial, siendo España uno de los países con mayor uso de la ecografía durante el embarazo. La aparición de nuevos marcadores de salud fetal, como son el estudio mediante Doppler pulsado del Ductus venoso fetal, en torno a la semana 14 de gestación, lleva asociada una mayor duración de las exposiciones en edades fetales muy tempranas. La posibilidad de un posible efecto dañino sobre el feto tras el uso del Doppler pulsado es una preocupación presente en la comunidad científica, siendo este tipo de exposiciones sometidos a los más estrictos controles de seguridad, mediante el control de las intensidades máximas de salida y…
