Lupinus mariae-josephi is a recently described endemic Lupinus species from a small area in Eastern Spain where it thrives in soils with active lime and high pH. The L. mariae-josephi root symbionts were shown to be very slow-growing bacteria with different phenotypic and symbiotic characteristics from those of Bradyrhizobium strains nodulating other Lupinus. Their phylogenetic status was examined by multilocus sequence analyses of four housekeeping genes (16S rRNA, glnII, recA, and atpD) and showed the existence of a distinct evolutionary lineage for L. mariae-josephi that also included Bradyrhizobium jicamae. Within this lineage, the tested isolates clustered in three different sub-groups that might correspond to novel sister Bradyrhizobium species. These core gene analyses consistently showed that all the endosymbiotic bacteria isolated from other Lupinus species of the Iberian Peninsula were related to strains of the B. canariense or B. japonicum lineages and were separate from the L. mariae-josephi isolates. Phylogenetic analysis based on nodC symbiotic gene sequences showed that L. mariae-josephi bacteria also constituted a new symbiotic lineage distant from those previously defined in the genus Bradyrhizobium. In contrast, the nodC genes of isolates from other Lupinus spp. from the Iberian Peninsula were again clearly related to the B. canariense and B. japonicum bv. genistearum lineages. Speciation of L. mariae-josephi bradyrhizobia may result from the colonization of a singular habitat by their unique legume host. © 2011 Elsevier GmbH.

Brassica insularis is a protected plant that grows on both coastal and inland cliffs in the western Mediterranean Basin. The objective of this study was to test if any variability exists in the salt stress response during seed germination and seedling development in this species relative to its provenance habitat. Variability among three populations in the salt stress effects on the seed germination and its recovery under different temperatures was evaluated. The effect of nebulisation of a salt solution on seedling development was evaluated between populations growing to different distance from the sea. Seeds of B. insularis could germinate at NaCl concentrations up to 200 mM. Its seed viability was negatively affected by salt, and the recovery ability decreased with increasing in temperature or salinity. Inter-population variability was detected in the salt response during the seed germination phase, as well as in seedling salt spray tolerance. The inland population seedlings showed a drastic decrease in survival and life span and failed to survive until the end of the experiment. By contrast, at least 90% of the coastal seedlings survived, even when sprayed at the highest frequency with the salt solution. This study allowed the investigation of two natural factors, soil salinity and marine aerosols, widely present in the B. insularis habitat and provided the first insights into the ecology of this protected species and its distribution in the Mediterranean. These results might be useful in understanding the actual distributions of other species with the same ecology that experience these same abiotic parameters. This article is protected by copyright.

The Valencian Plant Micro-reserves network comprises 298 protected sites, and considerable experience has been progressively accumulated during 15 years of continued management. However, an evaluation of its effectiveness as a tool to protect wild rare, endemic or endangered plants has not yet been made. As part of a larger evaluation effort, this paper assesses the effectiveness of the Valencian PMR network to incorporate the most relevant plants species targeted for conservation in the Valencian region. The results show that 77% of endemic, about 50% of rare and 57% of threatened species are represented in the PMR network. However, a comparison of these results is not possible today due to the lack of good analysis of networks of small protected sites focused on plant protection.

A postdoctoral researcher at the Universitat Jaume I has designed an innovative model for the selective recognition of nitrates, which is big news for the prevention of environmental pollution. The idea, developed by Vicente Martí-Centelles during a postdoctoral research stay at the University of Oxford, has been published in the prestigious journal Chemistry-A European Journal. The article describes the preparation of a sensor that can selectively detect the nitrate anion over all other anions, such as phosphate. The nitrate anion is a pollutant molecule found in fertilisers and, therefore, the water we drink and in rivers. At high levels, it is harmful to health and the environment. As a result of the blanket use of fertilisers in agriculture, the abundance of the nitrate anion has caused the alteration of the natural aquatic ecosystem. Moreover, water with elevated nitrate levels is thought to cause diseases such as methaemoglobinemia, also known as blue baby syndrome in infants, a disorder characterised by an abnormal accumulation of haemoglobin. The method proposed by Martí-Centelles paves the way for nitrate detection in water samples in different contexts, environmental or medical, to check for high levels and take preventive measures, where necessary. It is a ground-breaking model, with a purpose-designed chemical structure that homes in on this pollutant. This chemical structure is the first step towards an efficient recognition of nitrates and could find applications in the development of nitrate detection systems such as filters to remove these pollutants from water sources. Martí-Centelles explains: "User-friendly systems are possible where the molecule changes colour in the presence of nitrates, and even water filter systems similar to those that use resins that remove calcium from water. By including molecules based on our prototype, we can filter this nitrate from water, too." The research was carried out during a postdoctoral stay at the University of Oxford, supervised by Prof. Paul D. Beer, as part of the Generalitat Valenciana's VALi+d funding programme. It has been endorsed by UJI professor of organic chemistry, Santiago Luis Lafuente. The various stages were completed at Universitat Jaume I and the University of Oxford. Martí-Centelles also completed an industrial placement at Biotics at Espaitec, the Jaume I Science, Technology and Business Park, and completed his doctoral thesis at the UJI's Supramolecular and Sustainable Chemistry research group, led by Santiago Luis Lafuente.

This is a cross-sectional study in which we compared the perceived quality of life (QoL) of patients receiving outpatient treatment for cocaine (n = 727) and heroin dependence (n = 469), by analyzing differences by gender and time in treatment. Participants were recruited from addictive behavior centers in Spain in 2004. The World Health Organization Quality of Life Assessment Instrument (WHOQOL-Bref) was used as a measure. Analysis of covariance and multivariate linear regression were used. This study shows the relevance of considering the role of gender in QoL studies, and the need to evaluate the effectiveness of treatment in the improvement of QoL. Limitations of the study were noted. © 2014 Informa Healthcare USA, Inc.

InterCeram: International Ceramic Review | Year: 2012
The Eco-Management and Audit Scheme (EMAS) is a voluntary system, governed by Regulation (EC) No. 1221/2009, which enables member organizations to assess and improve their environmental performance and disseminate relevant information to the public and other stakeholders. Regulation (EC) No. 66/2010 on the EU Ecolabel, lays down rules for the establishment and implementation of a voluntary ecological labelling system, which aims to promote products and services that are eco-friendly throughout their life cycles and provide consumers with accurate, not misleading, and scientifically-based information on their environmental impact. Used together, the two tools, EMAS and EU Ecolabel, provide an opportunity for ceramic sector organizations to enhance their corporate image and reduce pressures from environmental authorities. This will improve relationships with customers, suppliers, governments and other stakeholders, and potentially open doors to new markets.

The aim of this paper is to study the quality of the websites of associations for people with polio and post-polio syndrome as an example of an important method for exchanging information and promoting the social visibility of physically disabled people. A descriptive cross-sectional study of 375 sites that met inclusion criteria, found using of the Google search engine, was carried out. The quality was studied through 22 variables, 8 of which make up the "Credibility Indicator". None of the websites met all the quality criteria nor all 8 items in the Credibility Index. A positive correlation between the variables of quality and credibility criteria (Pearson r = 0.81, p<0.001) was observed, therefore the Credibility Index is suggested as a useful tool for determining the quality of the websites. However, this tool must be supplemented with other qualitative approaches that explore both the contexts of lay-expert relationships and the function these sites serve.
