Deep-Sea Bioluminescence Blooms after Dense Water Formation at the Ocean Surface

2013

The deep ocean is the largest and least known ecosystem on Earth. It hosts numerous pelagic organisms, most of which are able to emit light. Here we present a unique data set consisting of a 2.5-year long record of light emission by deep-sea pelagic organisms, measured from December 2007 to June 2010 at the ANTARES underwater neutrino telescope in the deep NW Mediterranean Sea, jointly with synchronous hydrological records. This is the longest continuous time-series of deep-sea bioluminescence ever recorded. Our record reveals several weeks long, seasonal bioluminescence blooms with light intensity up to two orders of magnitude higher than background values, which correlate to changes in th…

Delineamientos de desarrollo local en tiempos de incertidumbre: oportunidad para otro tipo de planteamientos / / / \ \ \ Local development outlines i…

2020

Resumen: La pandemia de Covid-19 han impactado en todos los ámbitos sociales y aspectos comunitarios, sociales y subjetivos. En el desarrollo local y regional esta situación ha tenido unos efectos devastadores sobre los que todavía es temprano para evaluar sus efectos, de tal manera que es posible referirse a un “antes” y un “después”. En este escenario y contexto inédito de incertezas y riesgos, es posible referirse a la contingencia como un nuevo marco de descripción de las sociedades, en la que los conceptos teóricos del desarrollo local (y social en general) deberán explorar nuevos conceptos emergentes, como son, el riesgo y el peligro, y con ello, repensar la lógica y teorías del desar…

Con el título “RECUPERACIÓN, TRANSFORMACIÓN Y RESILIENCIA: EL PAPEL DEL TERRITORIO (DE LA ORDENACIÓN DEL TERRITORIO Y LAS POLÍTICAS TERRITORIALES)”, el X CIOT, coorganizado por FUNDICOT y la CONSELLERIA DE POLÍTICA TERRITORIAL, OBRAS PÚBLICAS Y MOVILIDAD de la GENERALITAT VALENCIANA los días 17, 18 y 19 de noviembre de 2021 fue el foro de debate y discusión sobre el necesario papel que una adecuada planificación y gestión de las políticas territoriales tiene a la hora de afrontar los sucesivos retos a los que las sociedades actuales se vienen enfrentando. Y lo hará desde los ámbitos académico y científico, técnico y de la toma de decisiones. Los contenidos se estructuran en torno a cuatro e…

Study of cosmic ray events with high muon multiplicity using the ALICE detector at the CERN Large Hadron Collider

2016

ALICE is one of four large experiments at the CERN Large Hadron Collider near Geneva, specially designed to study particle production in ultra-relativistic heavy-ion collisions. Located 52 meters underground with 28 meters of overburden rock, it has also been used to detect muons produced by cosmic ray interactions in the upper atmosphere. In this paper, we present the multiplicity distribution of these atmospheric muons and its comparison with Monte Carlo simulations. This analysis exploits the large size and excellent tracking capability of the ALICE Time Projection Chamber. A special emphasis is given to the study of high multiplicity events containing more than 100 reconstructed muons a…

An Immunogenic Peptide Derived from NM23-H2 Is Expressed on Bcr/abl+ Cells.

2006

Abstract Objective: Most tumors express antigens which, when presented by MHC molecules, can be recognized by cytotoxic T-lymphocytes. These tumor-associated-antigens (TAA) are considered to be key determinants in the graft-versus-tumor effect after allogeneic hematopoietic cell transplantation (HCT) and are therefore potential candidates for tumor vaccination. Unfortunately only small numbers of TAA have been isolated to date. In this project we looked for immunogenic peptides presented by bcr/abl+ cells of an HLA-A32 CML patient. Methods: Leukemia-specific mixed lymphocyte leukemia cell cultures (MLLC) were generated by co-culturing irradiated bcr/abl+ cells from the patient with peripher…

Identification of a Novel Pathway in BCR/ABL Signal Transduction Involving Akt-Independent Activation of PLC-gamma/mTOR/p70-S6K.

2006

Abstract In BCR/ABL positive CML, defining new, additional therapeutic targets in the pathways, activated by BCR/ABL is critical for the development of new treatment strategies, especially for patients resistant or refractory to Imatinib. While studying the involvement of PI3K/Akt/mTOR signaling pathway in the development of such resistance we have uncovered the existence of additional, Akt-independent mechanism of activation of mTOR/p70-S6 Kinase pathway. Short term treatment with Imatinib (1μM, 4 hours) of the BCR/ABL-positive cell lines LAMA84, AR320, KCL22, K562, Ba/F3-BCR/ABL caused downregulation of p70-S6K phosphorylation and of S6 ribosomal protein phosphorylation without decreasing…

The European Regional Convergence Process, 1980-1995: Do Spatial Regimes and Spatial Dependence Matter?

2002

International audience; The authors show that spatial dependence and spatial heterogeneity matter in the estimation of the ß-convergence process among 138 European regions over the 1980 to 1995 period. Using spatial econometrics tools, the authors detect both spatial dependence and spatial heterogeneity in the form of structural instability across spatial convergence clubs. The estimation of the appropriate spatial regimes spatial error model shows that the convergence process is different across regimes. The authors also estimate a strongly significant spatial spillover effect: the average growth rate of per capita GDP of a given region is positively affected by the average growth rate of …

An improvement of ComiR algorithm for microRNA target prediction by exploiting coding region sequences of mRNAs

2020

AbstractMicroRNA are small non-coding RNAs that post-transcriptionally regulate the expression levels of messenger RNAs. MicroRNA regulation activity depends on the recognition of binding sites located on mRNA molecules. ComiR is a web tool realized to predict the targets of a set of microRNAs, starting from their expression profile. ComiR was trained with the information regarding binding sites in the 3’utr region, by using a reliable dataset containing the targets of endogenously expressed microRNA in D. melanogaster S2 cells. This dataset was obtained by comparing the results from two different experimental approaches, i.e., inhibition, and immunoprecipitation of the AGO1 protein--a comp…

Collateral sensitivity of drug-resistant ABCB5- and mutation-activated EGFR overexpressing cells towards resveratrol due to modulation of SIRT1 expre…

2019

Abstract Background In the drug discovery field, natural products deemed a precious source of novel lead compounds. They have the ability to bypass or overcome multidrug resistance (MDR) in cancer cells. Purpose In this study, the natural polyphenolic stilbene resveratrol (RES) has been studied for its cytotoxic activity toward MDR cancer cells. Methods Resazurin assay was used to investigate the cytotoxicity of RES not only against a panel of drug-resistant cancer cells overexpressing P-glycoprotein/ABCB1, BCRP/ABCG2, ABCB5 (ATP-binding cassette transporters), but also mutation-activated EGFR. The assessment of proteins expression was done by Western blot analysis. COMPARE and hierarchical…
