Monitoring crustal movements and sea level in Lanzarote
The Institute of Astronomy and Geodesy is measuring sea level variations in Lanzarote Island by two automated tide gauges of precision since 1993. In order to obtain "real" sea level variations a permanent GPS station has been installed near the tide gauges. The goal of this GPS station is to measurement vertical crustal movements in order to obtain absolute sea level variations removing these movements from tide gauge data. A vertical tie with high accuracy between the reference point of the pillar where the GPS antenna is installed and the tide gauges bench marks is absolutely necessary. We have carried out this altimetric link yearly since year 2000. Methods of repeated geometric and trigonometric levelling of very short tracts have been used due to the great level difference existent. The control of the local stability of the pillar where the GPS antenna has been established, is carried out by a micro-geodetic control network building around it. This network of 13 benchmarks has been regularly observed by classic and GPS geodetic techniques in years 2000, 2001, 2002, 2003 and 2004. The data of these campaigns have been processed by different types of adjustments in the same reference system. The precision of the measurements and the reliability of the networks have been calculated. In this work the results obtained, the evaluation of the altimetric links and levelling campaigns, and the comparison of the levels of different measurements are presented
Urinary Microbiome: Yin and Yang of the Urinary Tract

comments and discussion.The application of next generation sequencing techniques has allowed the characterization of the urinary tract microbiome and has led to the rejection of the pre-established concept of sterility in the urinary bladder. Not only have microbial communities in the urinary tract been implicated in the maintenance of health but alterations in their composition have also been associated with different urinary pathologies, such as urinary tract infections (UTI). Therefore, the study of the urinary microbiome in healthy individuals, as well as its involvement in disease through the proliferation of opportunistic pathogens, could open a potential field of study, leading to new insights into prevention, diagnosis and treatment strategies for urinary pathologies. In this review we present an overview of the current state of knowledge about the urinary microbiome in health and disease, as well as its involvement in the development of new therapeutic strategies.Programa Estatal de Investigacio' n, Desarrollo e Innovacion Orientada a los Retos de la Sociedad

Targeting ribosomal G-quadruplexes with naphthalene-diimides as RNA polymerase I inhibitors for colorectal cancer treatment
17 pags., 6 figs., 2 tabs.Sanchez-Martin et al. report a mode of action for naphthalene-diimides, a well-known class of G-quadruplexes ligands.
Their work provides evidence of naphthalene-diimides targeting G-quadruplexes in ribosomal DNA, inducing
a blockade of RNA polymerase I-mediated transcription and cell death. These compounds could be exploited in
colorectal cancer treatment.This work was supported by the European Commission (TAR-

Prevention of ventilator-associated pneumonia: the multimodal approach of the spanish ICU pneumonia zero program.
Objectives:
The “Pneumonia Zero” project is a nationwide multimodal intervention based on the simultaneous implementation of a comprehensive evidence-based bundle measures to prevent ventilator-associated pneumonia in critically ill patients admitted to the ICU.
Design:
Prospective, interventional, and multicenter study.
Setting:
A total of 181 ICUs throughout Spain.
Patients:
All patients admitted for more than 24 hours to the participating ICUs between April 1, 2011, and December 31, 2012.
Intervention:
Ten ventilator-associated pneumonia prevention measures were implemented (seven were mandatory and three highly recommended). The database of the National ICU-Acquired Infections Surveillance Study (Estudio Nacional de Vigilancia de Infecciones Nosocomiales [ENVIN]) was used for data collection. Ventilator-associated pneumonia rate was expressed as incidence density per 1,000 ventilator days. Ventilator-associated pneumonia rates from the incorporation of the ICUs to the project, every 3 months, were compared with data of the ENVIN registry (April–June 2010) as the baseline period. Ventilator-associated pneumonia rates were adjusted by characteristics of the hospital, including size, type (public or private), and teaching (postgraduate) or university-affiliated (undergraduate) status.
Measurements and Main Results:
The 181 participating ICUs accounted for 75% of all ICUs in Spain. In a total of 171,237 ICU admissions, an artificial airway was present on 505,802 days (50.0% of days of stay in the ICU). A total of 3,474 ventilator-associated pneumonia episodes were diagnosed in 3,186 patients. The adjusted ventilator-associated pneumonia incidence density rate decreased from 9.83 (95% CI, 8.42–11.48) per 1,000 ventilator days in the baseline period to 4.34 (95% CI, 3.22–5.84) after 19–21 months of participation.
Conclusions:
Implementation of the bundle measures included in the “Pneumonia Zero” project resulted in a significant reduction of more than 50% of the incidence of ventilator-associated pneumonia in Spanish ICUs. This reduction was sustained 21 months after implementation
Gallic Acid: A Natural Phenolic Compound Exerting Antitumoral Activities in Colorectal Cancer via Interaction with G-Quadruplexes
Natural phenolic compounds have gained momentum for the prevention and treatment
of cancer, but their antitumoral mechanism of action is not yet well understood. In the present
study, we screened the antitumoral potential of several phenolic compounds in a cellular model of
colorectal cancer (CRC).We selected gallic acid (GA) as a candidate in terms of potency and selectivity
and extensively evaluated its biological activity. We report on the role of GA as a ligand of DNA
G-quadruplexes (G4s), explaining several of its antitumoral effects, including the transcriptional
inhibition of ribosomal and CMYC genes. In addition, GA shared with other established G4 ligands
some effects such as cell cycle arrest, nucleolar stress, and induction of DNA damage. We further
confirmed the antitumoral and G4-stabilizing properties of GA using a xenograft model of CRC.
Finally, we succinctly demonstrate that GA could be explored as a therapeutic agent in a patient
cohort with CRC. Our work reveals that GA, a natural bioactive compound present in the diet, affects
gene expression by interaction with G4s both in vitro and in vivo and paves the way towards G4s
targeting with phenolic compounds.Instituto de Salud Carlos IIIEuropean Commission PI21/00497

Evaluation of Over-The-Row Harvester Damage in a Super-High-Density Olive Orchard Using On-Board Sensing Techniques
New super-high-density (SHD) olive orchards designed for mechanical harvesting using over-the-row harvesters are becoming increasingly common around the world. Some studies regarding olive SHD harvesting have focused on the effective removal of the olive fruits; however, the energy applied to the canopy by the harvesting machine that can result in fruit damage, structural damage or extra stress on the trees has been little studied. Using conventional analyses, this study investigates the effects of different nominal speeds and beating frequencies on the removal efficiency and the potential for fruit damage, and it uses remote sensing to determine changes in the plant structures of two varieties of olive trees (‘Manzanilla Cacereña’ and ‘Manzanilla de Sevilla’) planted in SHD orchards harvested by an over-the-row harvester. ‘Manzanilla de Sevilla’ fruit was the least tolerant to damage, and for this variety, harvesting at the highest nominal speed led to the greatest percentage of fruits with cuts. Different vibration patterns were applied to the olive trees and were evaluated using triaxial accelerometers. The use of two light detection and ranging (LiDAR) sensing devices allowed us to evaluate structural changes in the studied olive trees. Before- and after-harvest measurements revealed significant differences in the LiDAR data analysis, particularly at the highest nominal speed. The results of this work show that the operating conditions of the harvester are key to minimising fruit damage and that a rapid estimate of the damage produced by an over-the-row harvester with contactless sensing could provide useful information for automatically adjusting the machine parameters in individual olive groves in the future.Ministerio de Economía y Competitividad AGL2013-46343-RJunta de Andalucía P12-AGR-122
