Use of Nanostructured Photocatalysts for Dye Degradation: A Review
Among the technologies proposed for wastewater treatment, the Advanced Oxidation Processes are viable and technological strategies for dyes degradation. Different photocatalytic systems classified in metal oxides alone or combined through hybrid composites or immobilized onto supports have been designed in various nanostructured shapes for their application in the photodegradation of polluting dyes. This review aims to describe the dyes as an environmental threat, photocatalysis as an effective process to remove dyes from water and provide an overview of the recent studies using photocatalytic systems grouped according to their development. Furthermore, this review describes the main parameters of a photocatalytic system with an important role in dye photodegradation. Finally, we discuss the limitations of photocatalysis for real industrial applications and the challenges for this environmental nanotechnology
Using MicroLEIS DSS to evaluate climate change impacts on land suitability in Andalusia, Spain
Comunicación oral presentada en la Sesión: SSS9.2: Studiying soils and/or land: Approaches for sustainable management of the environment.-- Congreso, celebrado del 7-12, abril 2013, en Viena, Austria.Understanding the effects of climate change on land suitability for crop production has become an important issue
with respect to food security in areas undergoing increasing population sizes. Land suitability for six common
Mediterranean crops was evaluated under current conditions and future climate change scenario. This evaluation
was performed using the Agro-ecological Decision Support System Micro LEIS (MicroLEIS DSS) through the
application of Terraza and Cervatana models.Peer reviewe

Age-related ultrastructural neurovascular changes in the female mouse cortex and hippocampus
Blood-Brain Barrier (BBB) breakdown occurs in ageing and neurodegenerative diseases. Although age-associated alterations have previously been described, most studies focused in male brains; hence, little is known about BBB breakdown in females. This study measured ultrastructural features in the ageing female BBB using transmission electron microscopy (TEM) and 3D reconstruction of cortical and hippocampal capillaries from 6- and 24-month-old female C57BL/6J mice. Aged cortical capillaries showed more changes than hippocampal capillaries. Specifically, aged cortex showed thicker basement membrane (BM), higher number and volume of endothelial pseudopods, decreased endothelial mitochondrial number, larger pericyte mitochondria, higher pericyte – endothelial cell contact and increased tight junction tortuosity compared to young animals. Only increased BM thickness and pericyte mitochondrial volume were observed in aged hippocampus. Regional comparison revealed significant differences in endothelial pseudopods and tight junctions between cortex and hippocampus of 24-month-old mice. Therefore, the ageing female BBB shows region-specific ultrastructural alterations that may lead to oxidative stress and abnormal capillary blood flow and barrier stability, potentially contributing to cerebrovascular diseases, particularly in post-menopausal women

Spatial analysis for assessing soil organic carbon stocks in southern Spain
Comunicación oral presentada al European Geosciences Union General Assembly 2012, que tuvo lugar del 22-27, abril, 2012, en Viena, Austria.The objectives of the present study were to estimate current soil organic carbon (SOC) stocks for each land use and
soil type, studying relationships between SOC stocks and selected environmental variables (elevation, temperature
and precipitation).Peer reviewe
Effects of Vaccinium berries (blueberries, cranberries and bilberries) on oxidative stress, inflammation, exercise performance, and recovery – a systematic review
This is the final version. Available on open access from the Royal Society of Chemistry via the DOI in this recordExercise-induced muscle damage is common in athletes and recreational exercisers and can lead to muscle soreness, weakness, and impaired muscle function. The precise mechanisms are unclear but oxidative stress and inflammation are thought to play a role. (Poly)phenols are substances abundant in Vaccinium berries that have been suggested to possess antioxidant and anti-inflammatory effects that could help improve exercise performance and/or recovery from exercise. The objective of this systematic review was to evaluate the benefits of Vaccinium berry supplementation on exercise performance and recovery, as well as on exercise-induced oxidative and inflammatory biomarkers in healthy individuals. A comprehensive search was conducted in PubMed, ProQuest Medline, Web of Science, Cochrane Library, and Scopus. Studies were included if the participants were healthy individuals who were supplemented with any Vaccinium berry or Vaccinium berry-based products in comparison to a control group. Of the 13 articles included in this review, no significant differences in the exercise performance were found and only one study reported benefits for markers of recovery. Interleukins and c-reactive protein were the most frequently reported biomarkers, but there was limited evidence that Vaccinium berry supplementation impacted them post-exercise. Most studies were of high quality and showed a low risk of bias. Vaccinium berry supplementation is not effective in modulating markers of exercise-induced inflammation and oxidative distress in healthy individuals; nevertheless, more studies are required to evaluate their effects on exercise performance and recovery in this population
European HYdropedological Data Inventory (EU-HYDI)
There is a common need for reliable hydropedological information in Europe. In the last decades research institutes, universities and government agencies have developed local, regional and national datasets containing soil physical, chemical, hydrological and taxonomic information often combined with land use and landform data. A hydrological database for western European soils was also created in the mid-1990s. However, a comprehensive European hydropedological database, with possible additional information on chemical parameters and land use is still missing.
A comprehensive joint European hydropedological inventory can serve multiple purposes, including scientific research, modelling and application of models on different geographical scales.
The objective of the joint effort of the participants is to establish the European Hydropedological Data Inventory (EU-HYDI). This database holds data from European soils focusing on soil physical, chemical and hydrological properties. It also contains information on geographical location, soil classification and land use/cover at the time of sampling. It was assembled with the aim of encompassing the soil variability in Europe. It contains data from 18 countries with contributions from 29 institutions. This report presents an overview of the database, details the individual contributed datasets and explains the quality assurance and harmonization process that lead to the final database
Hydrotherapy as a recovery strategy after exercise: a pragmatic controlled trial
Trial registration
ClinicalTrials.gov Identifier: NCT01765387Background
Our aim was to evaluate the recovery effects of hydrotherapy after aerobic exercise in cardiovascular, performance and perceived fatigue.
Methods
A pragmatic controlled repeated measures; single-blind trial was conducted. Thirty-four recreational sportspeople visited a Sport-Centre and were assigned to a Hydrotherapy group (experimental) or rest in a bed (control) after completing a spinning session. Main outcomes measures including blood pressure, heart rate, handgrip strength, vertical jump, self-perceived fatigue, and body temperature were assessed at baseline, immediately post-exercise and post-recovery. The hypothesis of interest was the session*time interaction.
Results
The analysis revealed significant session*time interactions for diastolic blood pressure (P=0.031), heart rate (P=0.041), self perceived fatigue (P=0.046), and body temperature (P=0.001); but not for vertical jump (P=0.437), handgrip (P=0.845) or systolic blood pressure (P=0.266). Post-hoc analysis revealed that hydrotherapy resulted in recovered heart rate and diastolic blood pressure similar to baseline values after the spinning session. Further, hydrotherapy resulted in decreased self-perceived fatigue after the spinning session.
Conclusions
Our results support that hydrotherapy is an adequate strategy to facilitate cardiovascular recovers and perceived fatigue, but not strength, after spinning exercise
