    Profound metabolic and structural changes are required for fleshy green fruits to ripen and become colorful and tasty. In tomato (Solanum lycopersicum), fruit ripening involves the differentiation of chromoplasts, specialized ...
  • Transcriptome analysis in tissue sectors with contrasting crocins accumulation provides novel insights into apocarotenoid biosynthesis and regulation during chromoplast biogenesis 

    Ahrazem, O.; Argandoña, J.; Fiore, A.; Aguado, C.; Luján, R.; Rubio-Moraga, A.; Marro, M.; Araujo-Andrade, C.; Loza-Alvarez, P.; Diretto, G.; Gómez-Gómez, L. (Nature, 2018-02-12)
    Article
    Accés obert
    Crocins, the red soluble apocarotenoids of saffron, accumulate in the flowers of Crocus species in a developmental and tissue-specific manner. In Crocus sieberi, crocins accumulate in stigmas but also in a distinct yellow ...
  • Synaptic phosphorylated a-synuclein in dementia with Lewy bodies 

    Colom-Cadena, Martí; Pegueroles, Jordi; Herrmann, Abigail G.; Henstridge, Christopher M.; Muñoz, Laia; Querol-Vilaseca, Marta; San Martin, Carla; Luque-Cabecerans, Joan; Clarimon, Jordi; Belbin, Olivia; Nuñez-Llaves, Raúl; Blesa, Rafael; Smith, Colin; McKenzie, Chris-Anne; Frosch, Matthew P.; Roe, Allyson; Fortea, Juan; Andilla, Jordi; Loza-Alvarez, Pablo; Gelpi, Ellen; Hyman, Bradley T.; Spires-Jone, Tara L.; Lleó, Alberto (Oxford, 2017-11-23)
    Article
    Accés obert
    Dementia with Lewy bodies is characterized by the accumulation of Lewy bodies and Lewy neurites in the CNS, both of which are composed mainly of aggregated a-synuclein phosphorylated at Ser129. Although phosphorylated ...
  • High-Resolution Morphological Approach to Analyse Elastic Laminae Injuries of the Ascending Aorta in a Murine Model of Marfan Syndrome 

    López-Guimet, Júlia; Andilla, Jordi; Loza-Álvarez, Pablo; Egea, Gustavo (Nature, 2017-05-04)
    Article
    Accés obert
    In Marfan syndrome, the tunica media is disrupted, which leads to the formation of ascending aortic aneurysms. Marfan aortic samples are histologically characterized by the fragmentation of elastic laminae. However, ...
  • STED imaging performance estimation by means of Fourier transform analysis 

    Merino, David; MALLABIABARRENA, ARRATE; ANDILLA, JORDI; ARTIGAS, DAVID; ZIMMERMANN, TIMO; LOZA-ALVAREZ, PABLO (OSA, 2017-04-17)
    Article
    Accés obert
    Due to relatively high powers used in STED, biological samples may be affected by the illumination in the process of image acquisition. Similarly, the performance of the system may be limited by the sample itself. ...
  • Polarized cortical tension drives zebrafish epiboly movements 

    Hernández-Vega, Amayra; Marsal, María; Pouille, Philippe-Alexandre; Tosi, Sebastien; Colombelli, Julien; Luque, Tomás; Navajas, Daniel; Pagonabarraga, Ignacio; Martín-Blanco, Enrique (EMBOpress, 2016-11-09)
    Article
    Accés obert
    The principles underlying the biomechanics of morphogenesis are largely unknown. Epiboly is an essential embryonic event in which three tissues coordinate to direct the expansion of the blastoderm. How and where forces ...
  • Two photon versus one photon fluorescence excitation in whispering gallery mode microresonators 

    Pastells, Carme; Marco, M. Pilar; Merino, David; Loza-Álvarez, Pablo; Pasquardini, Laura; Lorenzo, Lunelli; Pederzolli, Cecilia; Daldosso, Nicola; Farnesi, Daniele; Berneschi, Simone; Righini, Giancarlo C.; Quercioli, Franco; Conti, Gualtiero Nunzi; Soria, Silvia (ScienceDirect, 2016-02-01)
    Article
    Accés obert
    We investigate the feasibility of both one photon and two photon fluorescence excitation using whispering gallery mode microresonators. We report the linear and non linear fluorescence real-time detection of labeled IgG ...
  • Tomato fruit carotenoid biosynthesis is adjusted to actual ripening progression by a light-dependent mechanism 

    Llorente, Briardo; Andrea, Lucio D'; Aguila Ruiz-Sola, M.; Botterweg, Esther; Pulido, Pablo; Andilla, Jordi; Loza-Alvarez, Pablo; Rodriguez-Concepcion, Manuel (Wiley, 2016-01-01)
