Abstract
The ecological niche centrality hypothesis states that population abundance is determined by the position in the ecological niche, expecting higher abundances towards the center of the niche and lower at the periphery. However, the variations in the conditions that favor the persistence of populations between the center and the periphery of the niche can be a surrogate of stress factors that are reflected in the production of metabolites in plants. In this study we tested if metabolomic similarity and diversity in populations of the tree species Eucryphia cordifolia Cav. vary according to their position with respect to the structure of the ecological niche. We hypothesize that populations growing near the centroid should exhibit lower metabolites diversity than plants growing at the periphery of the niche. The ecological niche of the species was modeled using correlative approaches and bioclimatic variables to define central and peripheral localities from which we chose four populations to obtain their metabolomic information using UHPLC-DAD-QTOF-MS. We observed that populations farther away from the centroid tend to have higher metabolome diversity, thus supporting our expectation of the niche centrality hypothesis. Nonetheless, the Shannon index showed a marked variation in metabolome diversity at the seasonal level, with summer and autumn being the periods with higher metabolite diversity compared to winter and spring. We conclude that both the environmental variation throughout the year in combination with the structure of the ecological niche are relevant to understand the variation in expression of metabolites in plants.

Abstract
Fungal polysaccharides possess a broad biological activity, including cytotoxic and antioxidant activities. This work aimed to evaluate the cytotoxic and antioxidant activity of the acidic polysaccharides of Phylloporia boldo strain (named PBAP40). Cytotoxic activity of polysaccharide was evaluated determining the viability of three tumor cell lines by MTT assay. The effect of acidic polysaccharide on the cell cycle of HL-60 cell line was evaluated by flow cytometry, and the antioxidant activity was determined by DPPH and ABTS assays. PBAP40 showed cytotoxic effects in tumor cell lines. Results suggest that P. boldo acidic polysaccharides arrested tumor cells in the cell cycle Sub G1 phase. The acidic polysaccharides of PBAP40 strain were not cytotoxic for the non-tumor cell line. PBAP40 also showed excellent antioxidant activity. The FT-IR analysis of the acidic polysaccharides indicated the presence of glucans bearing α- and β- type glycosidic bonds.

Abstract
Despite its worldwide relevance as an invasive plant, there are few studies on Ulex europaeus (gorse) and its allelopathic activity is almost unexplored. The allelochemical profile of gorse was analysed through methanolic extract of pods and roots, and its phytotoxic effects on Lactuca sativa germination. The methanolic extract of pods had no effect in germination, while extract of roots resulted in a U-shaped dose-response curve: reducing the germination at concentration 0.5 mg mL-1. GC-MS analysis detected compounds with proven antimicrobial and antioxidant activities in the pods and cytotoxic compounds in the roots, which could explain the bioassay results. The quinolizidine alkaloids (QAs) composition was evaluated to predict possible biological functions. It showed the presence of QAs in gorse that are absent in their native range, indicating broad defense strategies against bacteria, fungi, plants, and insects in the Chilean ecosystem. This could explain the superiority of gorse in the invaded areas.

Abstract
INTRODUCTION There is no population-based study that accounts for the number of radical prostatectomies (RP) carried out in Spain, nor regarding the morbidity and mortality of this intervention. Our objective is to study the morbidity and mortality of RP in Spain from 2011 to 2015 and to evaluate the geographic variation. MATERIAL AND METHODS We designed a retrospective observational study of all patients submitted to RP in Spain during five consecutive years (2011-2015). The data was extracted from the «Conjunto Mínimo Básico de Datos» (CMBD). We have evaluated geographic variations in terms of morbidity and hospital stay, and the impact of the mean annual surgical volume for each center on these variables. RESULTS Between 2011-2015, a total of 37,725 RPs were performed in 221 Spanish public hospitals. The mean age of the series was 63.9±3.23 years. Of all RPs, 50% were performed through an open approach, and 43.4% have been operated on in hospitals with <500 beds. We observed an important variability in the distribution of the cases operated on in the different regions. The regions that perform more RPs are Andalusia, Catalonia, Galicia, and Madrid. Our study shows a complication rate of 8.6%, with hemorrhage and the need for transfusion being the most frequent (5.3 and 4%, respectively). There are significant differences in bleeding rates and hospital stay among regions, which are maintained after adjusting for patient characteristics and type of hospital. When studying the annual surgical volume of each hospital, we find that the impact on the rate of hemorrhage or transfusion is linear; however, hospital stay remains stable at around 5 days from 60 RPs/year. CONCLUSIONS In national terms, morbidity and mortality rates after RP are comparable to those described in the literature. This study reveals a clear dispersion in the hospitals that carry out this intervention, showing clear differences in terms of morbidity and hospital stay between the different regions.

Abstract
Scientific literature is full of works studying the removal of different pollutants from water through different Advanced Oxidation Processes (AOPs). Many of them only suggest it is reused for agricultural purposes or for small crops in pots. This study is based on the reuse of reclaimed agricultural wastewater contaminated with four insecticides (chlorantraniliprole, imidacloprid, pirimicarb and thiamethoxam) for growing lettuce in field conditions. First, solar photocatalysis with TiO2/Na2S2O8 was used on a pilot plant in a sunny area (Murcia, SE of Spain) as an environmentally friendly technology to remove insecticide residues and their main reaction intermediates from contaminated water. The necessary fluence (H, kJ m-2) to accomplish 90% removal (H90) ranged from 0.12 to 1212 kJ m-2 for pirimicarb and chlorantraniliprole, respectively. Only six (derived from imidacloprid, pirimicarb and thiametoxam) of 18 transformation intermediate products studied were detected in reclaimed water during the photoperiod (2000 kJ m-2 of accumulated UVA radiation) although all of them were totally photodegraded after a fluence of 1250 kJ m-2. Secondly, reclaimed agro-wastewater was used to irrigate two lettuce crops grown under greenhouse conditions and under agricultural field conditions. In no cases, insecticide residues nor their TIPs were noticed above their respective LOQs (limits of quantification) in soil and lettuce samples (between 0.03 and 0.04 μg kg-1 for pirimicarb and 2.49 and 2.23 μg kg-1 for thiamethoxam, respectively) when they were irrigated with reclaimed water, while residues of the four insecticides and some of their intermediates were found in soil and lettuce by the end of cultivation when they were irrigated with non-reclaimed contaminated water. According to the results, this technology can be applied in a sustainable way, mainly in areas with water scarcity and high solar radiation, contributing to water utilisation in drought areas and the use of renewable energy.

Abstract
The aim of this work was to know the differential composition of the dissolved fraction of a glyphosate-based herbicide (GBH), commercialized as GLIFOPAC, when reaches different aquatic environments and its ecotoxicological effects on crustaceans species living in them. Daphnia magna, Tisbe longicornis, and Emerita analoga were exposed to glyphosate herbicide called GLIFOPAC (480 g L-1 of active ingredient or a.i.) at concentrations between 0.5 and 4.8 g a.i. L-1. Acute toxicity in D. magna (48 h-LC50), E. analoga (48 h-LC50), and T. longicornis (96 h-LC50) was studied. Chromatographic analysis of the GBH composition used and water (freshwater/sea water) polluted with GLIFOPAC were evaluated. Results reported acute toxicity (48-96 h-LC50) values for D. magna, E. analoga and T. longicornis of 27.4 mg L-1, 806.4 mg L-1, and 19.4 mg L-1, respectively. Chromatographic evaluation described around 45 substances of the GLIFOPAC composition, such as from the surfactant structures (aliphatic chain with esther/ether group), metabolites (AMPA), and other substances (glucofuranose, glucopyranoside, galactopyranose). This study evidenced differences in the GLIFOPAC composition in freshwater and marine water, which may differentiate the toxic response at the crustacean-level in each aquatic environment.

Abstract
Background: Nance-Horan syndrome (NHS) is an X-linked rare congenital disorder caused by mutations in the NHS gene. Clinical manifestations include congenital cataracts, facial and dental dysmorphism and, in some cases, intellectual disability. The aim of the present work was to identify the genetic cause of this disease in two unrelated Spanish NHS families and to determine the relative involvement of this gene in the pathogenesis.Materials and methods: Four members of a two-generation family, three males and one female (Family 1), and seven members of a three-generation family, two males and five females (Family 2) were recruited and their index cases were screened for mutations in the NHS gene and 26 genes related with ocular congenital anomalies by NGS (Next Generation Sequencing).Results: Two pathogenic variants were found in the NHS gene: a nonsense mutation (p.Arg373X) and a frameshift mutation (p.His669ProfsX5). These mutations were found in the two unrelated NHS families with different clinical manifestations.Conclusions: In the present study, we identified two truncation mutations (one of them novel) in the NHS gene, associated with NHS. Given the wide clinical variability of this syndrome, NHS may be difficult to detect in individuals with subtle clinical manifestations or when congenital cataracts are the primary clinical manifestation which makes us suspect that it can be underdiagnosed. Combination of genetic studies and clinical examinations are essential for the clinical diagnosis optimization.

Abstract
Antarctica is still considered one of the few pristine areas in the globe. Despite this, several studies have shown phased out organic pollutants are present in several environmental abiotic and biological compartments. This study, based on blubber and fecal samples collected from five species of Antarctic pinnipeds, assessed the relationship between organochlorine pesticide (OCs) levels and trophic characterization using stable isotope analysis (δ13C and δ15N). The prevailing pollutants found in blubber were hexachlorocyclohexane isomers (HCHs), hexachlorobenzene (HCB), Heptachlor and Aldrin (0.84-564.11 ng g-1 l.w.). We also report a high presence of HCHs, Endrin, Dichlorodiphenyltrichloroethane (DDTs) and Methoxychlor (4.50-363.86 ng g-1 d.w.) in feces suggesting a detoxification mechanism. All the species tend towards high trophic positions (3.4-4.9), but with considerable variation in trophic niche and organochlorine pesticide concentrations per sampling site. This finding suggests that differences in pesticide levels in individuals are associated to foraging ecology.

Abstract
OBJECTIVES To evaluate the performance of rapid influenza diagnostic tests (RIDT) and influenza vaccines' effectiveness (VE) during an outbreak setting. METHODS We compared the performance of a RIDT with RT-PCR for influenza virus detection in influenza-like illness (ILI) patients enrolled during the 2016/17 season in Mexico City. Using the test-negative design, we estimated influenza VE in all participants and stratified by age, virus subtype, and vaccine type (trivalent vs quadrivalent inactivated vaccines). The protective value of some clinical variables was evaluated by regression analyses. RESULTS We enrolled 592 patients. RT-PCR detected 93 cases of influenza A(H1N1)pdm09, 55 of AH3N2, 141 of B, and 13 A/B virus infections. RIDT showed 90.7% sensitivity and 95.7% specificity for influenza A virus detection, and 91.5% sensitivity and 95.3% specificity for influenza B virus detection. Overall VE was 33.2% (95% CI: 3.0-54.0; p = 0.02) against any laboratory-confirmed influenza infection. VE estimates against influenza B were higher for the quadrivalent vaccine. Immunization and occupational exposure were protective factors against influenza. CONCLUSIONS The RIDT was useful to detect influenza cases during an outbreak setting. Effectiveness of 2016/17 influenza vaccines administered in Mexico was low but significant. Our data should be considered for future local epidemiological policies.

Abstract
INTRODUCTION The world population is ageing, and life expectancy is increasing. This situation will have a great impact on the management of patients with prostate cancer, especially in those of low risk, susceptible to a conservative management under active surveillance (AS). Regarding these patients' profile, it is necessary to answer the following questions: ¿for how long to continue with the AS scheme?, ¿which tests will be required?, ¿is it possible to carry out a transition to observation with oncological safety? The objective of this work is to analyse those patients with prostatic cancer who have been in AS with 75 years of age or more and assess the safety of the observation in an AS series with a long follow-up. MATERIAL AND METHODS We analysed our prospective cohort of AS patients between the years 1999 and 2018,including those who had been in follow-up with 75 years or more. They were offered treatment with curative intent when there were progression criteria and transition to observation under the urologist's decision. Some intermediate risk patients were included in the analysis. Comorbidity changes were analysed with the Charlson comorbidity index at entry and exit of AS. The progression and mortality of the patients were studied according to the management they received. RESULTS From 347 AS patients, 90 patients fulfilled the afore mentioned criteria and 15 (16.7%) were intermediate risk. The median follow-up was 6.4 years and 73 (81.1%) had low comorbidity (Charlson<2).There were 40 (44.4%) patients who left AS, 17 (18.9%) of them went to observationand the rest, 21 (23.3%), received curative treatment. There was a significant difference in comorbidity, measured by the Charlson index, at entry and exit of AS (P<.05) among patients receiving active treatment and the ones submitted to observation.No case of cancer-specific death or progression was observed in the observation group. CONCLUSION The transition from an active surveillance management to observation of prostate cancer elderly patients, as well as the decision to carry out a treatment with curative intent, seems controversial. In our series, this transition in patients older than 75 years does not increase the oncological risk.

Abstract
BACKGROUND/AIM Radiotherapy (RT) can lead to cardiovascular disease (CVD). Evidence suggests that radiation modulates miRNA levels. Our purpose was to assess the acute response to radiation-induced modulation of the expression of miRNA-146a, miRNA-155, miRNA-221, and miRNA-222, inflammatory response and endothelial dysfunction on endothelial cells. MATERIALS AND METHODS Human umbilical vein endothelial cells (HUVECs) were exposed to 2 Gy RT, and intracellular levels of selected miRNAs were measured by real-time polymerase chain reaction at 2 and 24 h. Cytokine and adhesion molecule release were also assessed. RESULTS Results showed that 2 Gy significantly increased the expression of miRNA-221 and miRNA-222, and reduced the level of miRNA-155 after 2 h; whereas miRNA-146a and miRNA-155 were significantly overexpressed and miRNA-222 was significantly down-regulated at 24 h. Interleukin-8 and soluble vascular cell adhesion molecule 1 levels were not affected by the studied RT. CONCLUSION RT at 2 Gy modulated expression of selected miRNAs by endothelial cells after 2 and 24 h, which might be related to CVD development in patients who receive RT.

Abstract
CONTEXT The objective of evidence-based medicine is to employ the best scientific information available to apply to clinical practice. Understanding and interpreting the scientific evidence involves understanding the available levels of evidence, where systematic reviews and meta-analyses of clinical trials are at the top of the levels-of-evidence pyramid. ACQUISITION OF EVIDENCE The review process should be well developed and planned to reduce biases and eliminate irrelevant and low-quality studies. The steps for implementing a systematic review include (i) correctly formulating the clinical question to answer (PICO), (ii) developing a protocol (inclusion and exclusion criteria), (iii) performing a detailed and broad literature search and (iv) screening the abstracts of the studies identified in the search and subsequently of the selected complete texts (PRISMA). SYNTHESIS OF THE EVIDENCE Once the studies have been selected, we need to (v) extract the necessary data into a form designed in the protocol to summarise the included studies, (vi) assess the biases of each study, identifying the quality of the available evidence, and (vii) develop tables and text that synthesise the evidence. CONCLUSIONS A systematic review involves a critical and reproducible summary of the results of the available publications on a particular topic or clinical question. To improve scientific writing, the methodology is shown in a structured manner to implement a systematic review.

Abstract
BACKGROUND Our main objective was to report the current use of active surveillance in Spain and to identify areas for potential improvement. METHODS A questionnaire generated by the Platform for Multicentre Studies of the Spanish Urology Association (AEU/PIEM/2014/0001, NCT02865330) was sent to all associate researchers from January to March 2016. The questionnaire included 7 domains covering various aspects of active surveillance. RESULTS Thirty-three of the 41 associate researchers responded to the questionnaire. Active surveillance is mainly controlled by the urology departments (87.9%). There was considerable heterogeneity in the classical clinical-pathological variables as selection criteria. Only 36.4% of the associate researchers used prostate-specific antigen density (PSAd). Multiparametric magnetic resonance imaging (mpMRI) was clearly underused as initial staging (6%). Only 27.3% of the researchers stated that their radiology colleagues had a high level of experience in mpMRI. In terms of the confirmation biopsy, most of the centres used the transrectal pathway, and only 2 out of 33 used the transperineal pathway or fusion software. Half of the researchers interviewed applied active treatment when faced with disease progression to Gleason 7 (3+4). There was no consensus on when to transition to an observation strategy. CONCLUSIONS The study showed the underutilisation of informed consent and quality-of-life questionnaires. PSAd was not included as a decisive element in the initial strategy for most researchers. There was a lack of confidence in the urologists' mpMRI experience and an underutilisation of the transperineal pathway. There was also no consensus on the follow-up protocols and active treatment criteria, confirming the need for prospective studies to analyse the role of mpMRI and biomarkers.

Abstract
The success of galling insects could be determined by synchronisation with host plant phenology and climate conditions, ensuring suitable oviposition sites for gall induction and food resources for their survival. The anatomical, histochemical and phenological synchronisation strategies between Calophya rubra (Blanchard) (Hemiptera: Psylloidea) and its host, the evergreen plant Schinus polygama (Cav.) (Cabrera) (Anacardiaceae), in the Mediterranean climate of southern Chile was evaluated and compared to that of the congeneric C. cf. duvauae (Scott) from Brazil and closely related host plant S. engleri in a subtropical climate. Anatomical, histometric, histochemical and vegetative phenology studies of the stem and galls were conducted from June 2015 to December 2016. Based on the anatomical, histometric and histochemical analysis, the conical stem gall traits imply gains over the non-galled stem toward the galling insect survival, but the maintenance of phellem, secretory ducts and pith indicate conservative developmental traits that cannot be manipulated by C. rubra. Our results indicate that the conditions of the Mediterranean climate zone limit C. rubra immature activity during unfavourable periods, probably determining a diapause period and a univoltine life cycle, which are peculiarities of the S. polygama- C. rubra system. The synchronisation between development and seasonality confers peculiarities to the S. polygama- C. rubra system in the Mediterranean climate zone.

Abstract
Summary
Objectives:
This paper presents a survey on HealthGrid technologies, describing the current status of Grid and eHealth and analyzing them in the medium-term future. The objective is to analyze the key points, barriers and driving forces for the take-up of HealthGrids.
Methods:
The article considers the procedures from other Grid disciplines such as high energy physics or biomolecular engineering and discusses the differences with respect to healthcare. It analyzes the status of the basic technology, the needs of the eHealth environment and the successes of current projects in health and other relevant disciplines.
Results:
Information and communication technology (ICT) in healthcare is a promising area for the use of the Grid. There are many driving forces that are fostering the application of the secure, pervasive, ubiquitous and transparent access to information and computing resources that Grid technologies can provide. However, there are many barriers that must be solved. Many technical problems that arise in eHealth (standardization of data, federation of databases, content-based knowledge extraction, and management of personal data …) can be solved with Grid technologies.
Conclusions:
The article presents the development of successful and demonstrative applications as the key for the take-up of HealthGrids, where short-term future medical applications will surely be biocomputing-oriented, and the future of Grid technologies on medical imaging seems promising. Finally, exploitation of HealthGrid is analyzed considering the curve of the adoption of ICT solutions and the definition of business models, which are far more complex than in other e-business technologies such ASP.

Abstract
INTRODUCTION The prognosis of patients diagnosed with metastatic prostate cancer seems to be modulated by factors such as the number and site of metastases. Our objective is to evaluate survival outcomes according to the number and site of metastases in our series of metastatic patients over the last 15 years. MATERIALS AND METHODS A retrospective analysis was performed on patients diagnosed between 1998 and 2014. We analyzed overall survival and progression-free survival, depending on the number and location of metastases on patients with newly diagnosed metastatic prostate cancer. Other potential prognostic factors were also evaluated: age, clinical stage, PSA at diagnosis, Gleason, PSA nadir, time till PSA nadir and first-line or second-line treatment after progression. RESULTS We analyzed a series of 162 patients. The mean age was 72.7yr (SD: 8.5). The estimated median overall survival was 3.9 yr (95% CI 2.6-5.2). The overall survival in patients with only lymph node metastases was 7 yr (95% CI 4.1-9.7), 3.9 (95%CI 2.3-5.5) in patients with only bone metastases, 2.5 yr (95% CI 2-2.3) in lymph nodes and bone metastases, and 2.2 yr (95% CI 1.4-3) in patients with visceral metastases (P<.001). In multivariate analysis, the location of metastasesis significantly associated with overall survival and progression-free survival. The number of metastases showed no association with survival. CONCLUSIONS The site of metastases has a clear impact on both overall survival and progression-free survival. Patients with only lymph node involvement had a better prognosis. The number of metastases showed no significant impact on survival in our series.

Abstract
BACKGROUND In the literature, mortality for radical cystectomy (RC) varies between 2.3% and 7.5%. In Spain, there are no published general data on morbidity and mortality. OBJECTIVE To identify the complications and mortality of RC in Spain through an analysis of all procedures performed over a 3-year period and to study the geographic variability of these results. MATERIAL AND METHODS We identified patients who underwent RC in the Spanish National Health System between 2011 and 2013 based on the minimum basic data set. We analysed the complications and mortality during hospitalisation and at 30, 60 and 90 days. We compared these results in the various autonomous communities, adjusted them by age, Charlson score and sex and subsequently added the hospital size. RESULTS We studied 7999 patients who underwent RC in 197 hospitals of the Spanish National Health System. The mean age of the series was 67.2±9.8 years. The median stay was 15 days (IQR, 11-24). Some 47.2% of the patients had complications. The mean mortality in-hospital and at 30, 60 and 90 days was 4.7, 2.9, 5 and 6.2%, respectively. There was considerable variability in the mortality at 90 days among the communities (3.8-9.1%). When adjusting by the patient and hospital characteristics, there were still significant geographic variations (3.8-11.5%). CONCLUSIONS RC mortality in Spain at 90 days is similar to the rate in the literature. There are significant geographic variations unexplained by the characteristics of the patients or by those of the hospitals in which these operations were performed.

Abstract
Inhibitors of the mechanistic target of rapamycin (mTOR) are currently used to treat advanced metastatic breast cancer. However, whether an aggressive phenotype is sustained through adaptation or resistance to mTOR inhibition remains unknown. Here, complementary studies in human tumors, cancer models and cell lines reveal transcriptional reprogramming that supports metastasis in response to mTOR inhibition. This cancer feature is driven by EVI1 and SOX9. EVI1 functionally cooperates with and positively regulates SOX9, and promotes the transcriptional upregulation of key mTOR pathway components (REHB and RAPTOR) and of lung metastasis mediators (FSCN1 and SPARC). The expression of EVI1 and SOX9 is associated with stem cell-like and metastasis signatures, and their depletion impairs the metastatic potential of breast cancer cells. These results establish the mechanistic link between resistance to mTOR inhibition and cancer metastatic potential, thus enhancing our understanding of mTOR targeting failure.

Abstract
BACKGROUND Lymphadenectomy for prostate cancer (PC) is the most reliable procedure for detecting lymphatic metastases. The optimal extension of this procedure is still a topic of debate. OBJECTIVE To analyse the diagnostic performance and complications of extended lymphadenectomy (ELD) and limited lymphadenectomy (LLD) in a series of patients with high-risk PC who underwent radical prostatectomy (RP). MATERIAL AND METHODS A retrospective study was conducted on patients with high d'Amico risk who underwent RP with lymphadenectomy between 1999 and 2014. A comparative analysis was performed of the diagnostic capacity of lymphatic metastases of ELD and LLD and of postoperative complications at 90 days. RESULTS Ninety-three patients were analysed, 20 (21.5%) and 73 (78.5%) of whom underwent ELD and LLD, respectively. The mean age of the series was 65.26 years (SD, 5.51). The median follow-up was 1.51 (0.61-2.29) years in the ELD group and 5.94 (3.61-9.10) in the LLD group. The median number of nodes obtained was 13 (9-23) in the ELD group compared with 5 (2-8) in the LLD group (p <.001). The percentages of patients with positive nodes in the ELD and LLD groups were 35% and 5.47%, respectively (p <.001). The overall complication rate at 90 days was 35.5% (33 patients). In the ELD group, 12 patients (60%) had complications, compared with 21 patients (28.8%) in the LLD group (p=.016), with no significant differences in severity according to the Clavien scale (p=.73). CONCLUSIONS In our series, the detection of metastatic nodes was significantly greater with ELD. ELD increases the number of complications, with no differences compared with LLD in severity according to the modified Clavien scale.

Abstract
The distribution of Acacia dealbata Link (Fabaceae) in its non-native range is associated with disturbed areas. However, the possibility that it can penetrate the native forest during the invasion process cannot be ruled out. This statement is supported by the fact that this species has been experimentally established successfully under the canopy of native forest. Nonetheless, it is unknown whether A. dealbata can express shade tolerance traits to help increase its invasive potential. We investigated the shade tolerance of A. dealbata under the canopy of two native forests and one non-native for three consecutive years, as well as its early growth and photosynthetic performance at low light intensities (9, 30, and 70 μmol m−2sec−1) under controlled conditions. We found many A. dealbata plants surviving and growing under the canopy of native and non-native forests. The number of plants of this invasive species remained almost constant under the canopy of native forests during the years of study. However, the largest number of A. dealbata plants was found under the canopy of non-native forest. In every case, the distribution pattern varied with a highest density of plants in forest edges decreasing progressively toward the inside. Germination and early growth of A. dealbata were slow but successful at three low light intensities tested under controlled conditions. For all tested light regimes, we observed that in this species, most of the energy was dissipated by photochemical processes, in accordance with the high photosynthetic rates that this plant showed, despite the really low light intensities under which it was grown. Our study reveals that A. dealbata expressed shade tolerance traits under the canopy of native and non-native forests. This behavior is supported by the efficient photosynthetic performance that A. dealbata showed at low light intensities. Therefore, these results suggest that Mediterranean forest ecosystems of South America can become progressively invaded by A. dealbata and provide a basis for estimating the possible impacts that this invasive species can cause in these ecosystems in a timescale.

Abstract
AIM To evaluate the effect of lymphadenectomy and/or radiotherapy on recurrence and survival patterns in endometrial carcinoma (EC) in a radiotherapy reference centre population. MATERIAL AND METHODS A retrospective population-based review was conducted on 261 patients with stages I-III EC. Univariate and multivariate analyses were carried out. Both recurrence and survival were analysed according to patient age, FIGO stage, tumour size, myometrial invasion, tumour grade, lymphadenectomy, external beam irradiation (EBI), and brachytherapy (BT). RESULTS Median age: 64.8 years. Median follow-up: 151 months. The following treatments were administered: surgery, 97.32%; lymph-node dissection, 54.4%; radiotherapy, 162 patients (62%) (EBI and BT: 64.1%, BT alone: 30.2%, EBI alone: 5.6%). Twenty-six patients (9.96%) suffered loco-regional recurrence, whilst 27 (10.34%) suffered distant failure. The 5-year overall survival (OS) for all stages was 80.1%. The 5-year disease free survival (DFS) was 92.1% for all patients. The 10-year DFS was 89.9%. The independent significant prognostic factors for a good outcome identified through the multivariate analysis were: age <75 years (p = 0.001); tumour size ≤2 cm (p = 0.003); myometrial invasion ≤50% (p = 0.011); lymphadenectomy (p = 0.02); EBI (p = 0.001); and BT (p = 0.031). Toxicity occurred in 114 of the 162 patients who received radiotherapy (70.5%). The toxicity was mainly acute, and late in only 28.3% (n = 45) of cases. The majority experienced G1-2 toxicity, and only 3% of patients experienced G3 late toxicity (5/162). CONCLUSIONS Our results suggest that age <75 years, tumour size ≤2 cm, myometrial invasion ≤50%, lymphadenectomy, EBI, and BT, are predictors of a good outcome in EC.

Abstract
OBJECTIVE To assess the safety of hospital discharge 24 hours after laparoscopic radical prostatectomy and to identify possible factors associated with longer hospital stays. MATERIAL AND METHODS Retrospective study of patients diagnosed with localized prostate cancer underwent to laparoscopic radical prostatectomy consecutively between May of 2007 and December of 2010. Those patients who met the following requirements were discharged in less than 24 hours: absence of complications, drainage debit minor than 50 cc, normal oral tolerance, no significant bladder haematuria and good functional recovery. Logistic regression analysis was conducted in order to assess the possible associated variables with longer hospital stays. RESULTS A total of 266 patients were analysed. The follow-up median was 34 months. Eighty patients (30.1%) were discharged in less than 24 hours. Average stay (SD) of all series was 2.9 days (3.08). Solely HTA, neurovascular bundles sparing and the development of lymphadenectomy were statistically significant between both groups in univariate analysis (discharge<24 hours vs. discharge>24 hours). In multivariate analysis, only HTA (OR=1.98 [CI 95%:1.13-3.47], P=.016) and lymphadenectomy performance (OR=2.56 [CI 95%:1.18-5.56] P=.017) were independent predictive variables of hospital stays longer than 24 hours. CONCLUSIONS Early hospital discharge of patients underwent to LRP is feasible and safe. In our series, the lymphadenectomy performance and the HTA were associated factors to longer hospital stay.

Abstract
PURPOSE Treating patients with large or pendulous breasts is challenging. Although brassiere cups are currently in use, no study has yet been carried out to assess their dosimetric impact. The aim of the present study was to evaluate the possible dosimetric advantages of the use of breast cups on patients with large or pendulous breasts. MATERIALS AND METHODS Two CT studies were carried out on 12 breast cancer patients with large or pendulous breasts, with one study involving the use of breast cups. Radiation plans were developed in accordance with each of the CT studies. The following were compared: planning target volume (PTV), volume irradiated by the 95% isodose, conformity index, homogeneity index, mean lung dose, and mean heart dose was also compared for left breast treatment. The plan involving the use of cups was found to be the best option, leading to all patients being treated with cups. The resulting acute toxicity and cosmesis were also recorded. Both scenarios involved the use of film dosimetry to evaluate the skin doses. RESULTS The use of breast cups resulted in a significant reduction of the PTV volume (from 1640 cm3 to 1283 cm3), of the irradiated volume (from 2154 cm3 to 1477 cm3) and of the conformity index (from 1383 to 1213). Despite slight improvements in the homogeneity index (from 0.12 to 0.10), statistical significance was not attained. The use of breast cups also led to significant dose reductions in V20 for lung (from 13.7% to 1.7%) and V5 for heart (from 9.8% to 2.7%). No differences in acute toxicity or cosmesis were observed compared to patients treated without cups. CONCLUSIONS Our results show that the use of brassiere cups during breast radiation therapy leads to improvements in the main dosimetric factors analyzed. Furthermore, modifications to standard irradiation protocols are not required. In summary, we consider the technique of using breast cups with radiation therapy highly appropriate when treating breast cancer patients with large or pendulous breasts.

Abstract
The goal of this work was to evaluate a washing process that uses organic solutions for polychlorinated biphenyl (PCB)-contaminated soil, and includes an ultrasound pre-treatment step to reduce operational times and organic solvent losses. In a preliminary trial, the suitability of 10 washing solutions of different polarities were tested, from which three n-hexane-based solutions were selected for further evaluation. A second set of experiments was designed using a three-level Taguchi L27 orthogonal array to model the desorption processes of seven different PCB congeners in terms of the variability of their PCB concentration levels, polarity of the washing solution, sonication time, the ratio washing solution/soil, number of extraction steps and total washing time. Linear models were developed for the desorption processes of all congeners. These models provide a good fit with the results obtained. Moreover, statistically significant outcomes were achieved from the analysis of variance tests carried out. It was determined that sonication time and ratio of washing solution/soil were the most influential process parameters. For this reason they were studied in a third set of experiments, constructed as a full factorial design. The process was eventually optimized, achieving desorption rates of more than 90% for all congeners, thus obtaining concentrations lower than 5 ppb in all cases. The use of an ultrasound-assisted soil washing process for PCB-contaminated soils that uses organic solvents seems therefore to be a viable option, especially with the incorporation of an extra step in the sonication process relating to temperature control, which is intended to prevent the loss of the lighter congeners.

Abstract
Aryl Hydrocarbon Receptor (AhR) ligands also known as dioxin-like compounds, constitute a substantial part of the total toxicity from many pollution sources, including pulp mill effluents. The aim of this article was to evaluate dioxin-like activity in different kraft mill effluents by a combination of yeast bioassays and gas chromatography-mass spectrometry (GC-MS) chemical analysis. The study includes kraft mill effluents from three sources of raw material: Pinus radiata, Eucalyptus globulus and a combination of both (50% each). The Recombinant Yeast Assay (RYA) showed an effective concentration of AhR ligands more than 30-fold higher in Eucalyptus globulus than in Pinus radiata effluents. Our results suggest that specific ligands, rather than the total amount of extractive material, determined the observed activity. Analysis of extract composition by GC-MS indicated that moderately hydrophobic aromatic compounds were likely responsible for the observed dioxin-like activity. In particular, benzaldehyde derivatives appeared as candidates for eliciting the observed dioxin-like activity in pulp mill effluents, giving their structural properties and their high concentration in AhR ligand-rich samples.

Abstract
The Biobío River basin is highly impacted by a variety of anthropogenic activities such as pulp mills and urban wastewaters subjected to different treatment processes. This work assesses for the first time, the contamination source and biological effects (estrogenic and dioxin-like activities) in the river basin by the determination of 45 organic microcontaminants in seven sediment samples. Pressurized solvent extraction combined with two-dimensional comprehensive gas chromatography coupled to time of flight mass spectrometry was employed for this purpose. The organic microcontaminants identified comprise monoterpenes, sesquiterpenes, diterpenes, ionones, lineal alkyl benzenes, polycyclic aromatic hydrocarbons, musk fragrances, sterols and phathalate esters. The presence of pine and eucalyptus pulp mill effluents increased the abundance of resin-derived neutral compounds and monoterpenes respectively. A principal component analysis showed that the Biobío River basin was impacted by domestic wastewater treatment plants (WWTPs), pine or eucalyptus Kraft pulp mills and pyrolytic and pyrogenic processes. Finally, the recombinant yeast assays showed that the presence of estrogenic and dioxin-like activity was mostly located in sediments impacted by domestic WWTP effluents.

Abstract
Low-dose radiotherapy (LD-RT) has been used for several benign diseases, including arthrodegenerative and inflammatory pathologies. Despite its effectiveness in clinical practice, little is known about the mechanisms through which LD-RT modulates the various phases of the inflammatory response and about the optimal dose fractionation. The objective of this review is to deepen knowledge about the most effective LD-RT treatment schedule and radiobiological mechanisms underlying the anti-inflammatory effects of LD-RT in various in vitro experiments, in vivo studies, and clinical studies.
