Nivelación hidrostática entre dos mareógrafos situados en el Puerto de Barcelona
Este estudio pretende relacionar los registros (marzo de 2013 a febrero de 2014) de dos mareógrafos situados en el
Puerto de Barcelona y que se han denominado BCN2 y BCN3. El mareógrafo BCN2 pertenece a la RED de MAReógrafos
de Puertos del Estado (REDMAR) y refiere los datos al NMMA1995 mientras que BCN3, propiedad de la Autoridad
Portuaria de Barcelona, los refiere a la Red Topográfica del Puerto de Barcelona observada mediante técnicas GNSS.
Ambos mareógrafos están separados unos 3Km. en línea recta y unos 8Km. por tierra. El objetivo ha sido determinar
la diferencia existente entre los ceros de referencia de los dos mareógrafos. El nivel de mar observado por los mareógrafos,
sin tener en cuenta la acción del oleaje, está afectado por la marea astronómica y la marea meteorológica. La
marea meteorológica es de tipo aleatorio, por el contrario la marea astronómica es de carácter determinista y se puede
resolver realizando el análisis de armónicos. Para ello, una vez realizado el control de calidad de los datos brutos, se
utilizó la aplicación T_TIDE en MATLAB obteniendo como resultado para cada mareógrafo tres gráficas y dos ficheros.
Las gráficas representan respectivamente el nivel del mar observado, la marea astronómica y la meteorológica o residuo
y de los dos ficheros, uno corresponde al cálculo de los componentes armónicos, del que nos interesa la componente
Z0 (nivel medio del mar) y el segundo contiene la componente meteorológica. Se puede concluir en que el cero
de referencia de BCN3 está situado 0,096 metros por encima del NMMA 1995.Peer ReviewedPostprint (published version
Acetylome in Human Fibroblasts From Parkinson's Disease Patients
Parkinson's disease (PD) is a multifactorial neurodegenerative disorder. The pathogenesis of this disease is associated with gene and environmental factors. Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most frequent genetic cause of familial and sporadic PD. Moreover, posttranslational modifications, including protein acetylation, are involved in the molecular mechanism of PD. Acetylation of lysine proteins is a dynamic process that is modulated in PD. In this descriptive study, we characterized the acetylated proteins and peptides in primary fibroblasts from idiopathic PD (IPD) and genetic PD harboring G2019S or R1441G LRRK2 mutations. Identified acetylated peptides are modulated between individuals' groups. Although acetylated nuclear proteins are the most represented in cells, they are hypoacetylated in IPD. Results display that the level of hyperacetylated and hypoacetylated peptides are, respectively, enhanced in genetic PD and in IPD cells
The Baleares 2013 Calibration Campaign of Jason-2 and Saral Altimeters
The 2013 Balearic campaign GNSS position analysis of the 2013 will be performed with different softwares by different groups (similarly as it is being done in
the International GNSS Service for their different products), in order improve the high demanded accuracy for JASON2 and SARAL altimeters precise calibration.
In particular JPL GIPSY-OASIS software will be used, with the undifferenced PPP ambiguity fixing strategy. In order to improve the results accuracy, two similar
networks are being processed. The first network includes the deployed GNSS receivers and the reference stations. The second one is a control network, defined
by using the permanent receivers in the California dense network with a similar distribution as the main altimeter campaign network. In this case, the position of
the receivers plying the role of buoys are being processed in the same kinematic way than the actual buoys, in order to compare them with the very accurate
positions obtained with GIPSY-OASIS static processing.Postprint (published version
Regulation of cell death receptor S-nitrosylation and apoptotic signaling by Sorafenib in hepatoblastoma cells
Nitric oxide (NO) plays a relevant role during cell death regulation in tumor cells. The overexpression of nitric oxide synthase type III (NOS-3) induces oxidative and nitrosative stress, p53 and cell death receptor expression and apoptosis in hepatoblastoma cells. S-nitrosylation of cell death receptor modulates apoptosis. Sorafenib is the unique recommended molecular-targeted drug for the treatment of patients with advanced hepatocellular carcinoma. The present study was addressed to elucidate the potential role of NO during Sorafenib-induced cell death in HepG2 cells. We determined the intra- and extracellular NO concentration, cell death receptor expression and their S-nitrosylation modifications, and apoptotic signaling in Sorafenib-treated HepG2 cells. The effect of NO donors on above parameters has also been determined. Sorafenib induced apoptosis in HepG2 cells. However, low concentration of the drug (10nM) increased cell death receptor expression, as well as caspase-8 and -9 activation, but without activation of downstream apoptotic markers. In contrast, Sorafenib (10 µM) reduced upstream apoptotic parameters but increased caspase-3 activation and DNA fragmentation in HepG2 cells. The shift of cell death signaling pathway was associated with a reduction of S-nitrosylation of cell death receptors in Sorafenib-treated cells. The administration of NO donors increased S-nitrosylation of cell death receptors and overall induction of cell death markers in control and Sorafenib-treated cells. In conclusion, Sorafenib induced alteration of cell death receptor S-nitrosylation status which may have a relevant repercussion on cell death signaling in hepatoblastoma cells.Instituto de Salud Carlos III PI13/00021Ministerio de Economía y Competitividad BFU2012-32056Consejería de Economía, Innovación, Ciencia y Empleo, Junta de Andalucía BIO-0216Consejería de Economía, Innovación, Ciencia y Empleo, Junta de Andalucía CTS-6264Consejería de Salud, Junta de Andalucía PI13/ 0002
Cold ischemia >4 hours increases heart transplantation mortality. An analysis of the Spanish heart transplantation registry
[Abstract]
Background.
Cold ischemia time (CIT) has been associated to heart transplantation (HT) prognosis. However, there is still uncertainty regarding the CIT cutoff value that might have relevant clinical implications.
Methods.
We analyzed all adults that received a first HT during the period 2008–2018. CIT was defined as the time between the cross-clamp of the donor aorta and the reperfusion of the heart. Primary outcome was 1-month mortality.
Results.
We included 2629 patients, mean age was 53.3 ± 12.1 years and 655 (24.9%) were female. Mean CIT was 202 ± 67 min (minimum 20 min, maximum 600 min). One-month mortality per CIT quartile was 9, 12, 13, and 19%. One-year mortality per CIT quartile was 16, 19, 21, and 28%. CIT was an independent predictor of 1-month mortality, but only in the last quartile of CIT >246 min (odds ratio 2.1, 95% confidence interval 1.49–3.08, p < .001). We found no relevant differences in CIT during the study period. However, the impact of CIT in 1-month and 1-year mortality decreased with time (p value for the distribution of ischemic time by year 0.01), particularly during the last 5 years.
Conclusions.
Although the impact of CIT in HT prognosis seems to be decreasing in the last years, CIT in the last quartile (>246 min) is associated with 1-month and 1-year mortality. Our findings suggest the need to limit HT with CIT > 246 min or to use different myocardial preservation systems if the expected CIT is >4 h
Impact of the “Law on promotion of personal autonomy and care for people dependent” in population with severe mental disorder
Law 39/2006, known as Dependence
Law, has generated skepticism since its
approval, for being focused on dependancy and
barely promoting personal autonomy, treating it
as a secondary issue.
As it relates to people with severe mental disorder,
a major concern to mental health professional
organizations and family associations
has been the compatibility of the law with the
services provided by the National health service
and whether the established selection criteria for
qualifying for the service fits the needs of this
group.
This article reflects the work done across several
Spanish autonomous regions by different professionals
in an attempt to convince the administration
to make the necessary adjustment to suit
the characteristics of people with serious mental
disorders.
After discussing its strengths and weaknesses, it
outlines three different ways to offset their risks
in three different regions, Extremadura, Andalucia
and Madrid. Finally it addresses the key aspects
of the law which need to be worked on, in
order to become a benefit for people with severe
mental disorder, and not a barrierLa Ley 39/2006, conocida como Ley de Dependencia, ha generado, desde su aprobación, desconfianza
por estar enfocada a la atención a la dependencia,
siendo la promoción de la autonomía personal
un elemento apenas desarrollado y secundario.
En el caso de las personas con trastorno mental grave,
lo que mayor preocupación ha causado a las organizaciones
de profesionales de la salud mental y a las
asociaciones de familiares ha sido la compatibilidad de
dicha Ley con las prestaciones del Sistema Nacional
de Salud y si el baremo establecido se ajustaba a las
necesidades de este colectivo.
Este artículo recoge el trabajo realizado desde diferentes
comunidades autónomas por diferentes profesionales
en un intento de, tras un análisis de la Ley,
plantear a la administración responsable de la misma
el necesario ajuste para adaptarla a las características
de las personas con trastorno mental grave.
Se analizan, en primer lugar, sus fortalezas y debilidades.
Posteriormente se exponen tres formas diferentes
de contrarrestar sus riesgos, en tres comunidades autónomas
diferentes, Extremadura, Andalucía y Madrid.
Finalmente se dan las claves de los aspectos de la Ley
sobre los que hay que seguir trabajando para que sea
una oportunidad para las personas con trastorno mental
grave, y no una barrer
Nature of viruses and pandemics: Coronaviruses
Coronaviruses (CoVs) have the largest genome among RNA viruses and store large amounts of information without genome integration as they replicate in the cell cytoplasm. The replication of the virus is a continuous process, whereas the transcription of the subgenomic mRNAs is a discontinuous one, involving a template switch, which resembles a high frequency recombination mechanism that may favor virus genome variability. The origin of the three deadly human CoVs SARS-CoV, MERS-CoV and SARS-CoV-2 are zoonotic events. SARS-CoV-2 has incorporated in its spike protein a furine proteolytic site that facilitates the activation of the virus in any tissue, making this CoV strain highly polytropic and pathogenic. Using MERS-CoV as a model, a propagation-deficient RNA replicon was generated by removing E protein gene (essential for viral morphogenesis and involved in virulence), and accessory genes 3, 4a, 4b and 5 (responsible for antagonism of the innate immune response) to attenuate the virus: MERS-CoV-Δ[3,4a,4b,5,E]. This RNA replicon is strongly attenuated and elicits sterilizing protection after a single immunization in transgenic mice with the receptor for MERS-CoV, making it a promising vaccine candidate for this virus and an interesting platform for vector-based vaccine development. A strategy could be developed for the design of RNA replicon vaccines for other human pathogenic coronaviruses.This work was supported by grants from the Government of Spain (PID2019-107001RB-I00 AEI/FEDER, UE; SEV 2017-0712 and PIE_INTRAMURAL_LINEA 1-202020E079), the CSIC (PIE_INTRAMURAL-202020E043), the European Commission (ISOLDA_848166 H2020-SC1-2019-Two-Stage-RTD, RIA; MANCO_101003651 H2020-SC1-PHE-CORONAVIRUS-2020 RIA), and the U.S. National Institutes of Health (NIH_2P01AI060699).Peer reviewe
