Construcción sociocultural de las emociones en el proceso del cuidado en la vejez en un contexto de exclusión social urbana. Prácticas y significados de mujeres adultas mayores y el cuidador(a), en sus comunidades de vida y sentido.

Esta investigación indaga sobre las emociones, los significados y las formas de regulación que se presentan en la construcción de las prácticas en el proceso del cuidado de mujeres adultas mayores. El estudio se realizó en dos municipios de la zona metropolitana de Guadalajara con un alto índice de adultos mayores que viven en marginación y exclusión social. Este trabajo tiene el afán de aportar conocimientos sobre el papel que tiene la comunicación al momento de intercambiar significados, los procesos comunicativos y el sentido que se configura y reproduce en la transmisión de significados en relación a las emociones que se gestan en el proceso de cuidar. Se da cuenta del lugar que ocupan las emociones en mujeres adultas mayores y en sus cuidadores principales, al estar ambos inmersos en un contexto de exclusión social urbana.Consejo Nacional de Ciencia y Tecnologí

Induced systemic resistance against Botrytis cinerea by Micromonospora strains isolated from root nodules

This article is part of the Research Topic: Harnessing useful rhizosphere microorganisms for pathogen and pest biocontrol.-- Edited by: Aurelio Ciancio, Corné M. J. Pieterse and Jesús Mercado-Blanco.Micromonospora is a Gram positive bacterium that can be isolated from nitrogen fixing nodules from healthy leguminous plants, where they could be beneficial to the plant. Their plant growth promoting activity in legume and non-legume plants has been previously demonstrated. The present study explores the ability of Micromonospora strains to control fungal pathogens and to stimulate plant immunity. Micromonospora strains isolated from surface sterilized nodules of alfalfa showed in vitro antifungal activity against several pathogenic fungi. Moreover, root inoculation of tomato plants with these Micromonospora strains effectively reduced leaf infection by the fungal pathogen Botrytis cinerea, despite spatial separation between both microorganisms. This induced systemic resistance, confirmed in different tomato cultivars, is long lasting. Gene expression analyses evidenced that Micromonospora stimulates the plant capacity to activate defense mechanisms upon pathogen attack. The defensive response of tomato plants inoculated with Micromonospora spp. differs from that of non-inoculated plants, showing a stronger induction of jasmonate-regulated defenses when the plant is challenged with a pathogen. The hypothesis of jasmonates playing a key role in this defense priming effect was confirmed using defense-impaired tomato mutants, since the JA-deficient line def1 was unable to display a long term induced resistance upon Micromonospora spp. inoculation. In conclusion, nodule isolated Micromonospora strains should be considered excellent candidates as biocontrol agents as they combine both direct antifungal activity against plant pathogens and the ability to prime plant immunity.This work was supported by MICINN Grant AGL2010-17380 and AGL-2012-39923.

The results confirm that the videos of experts are an essential educational resource for learning in a MOOC, similarly, the discussion forums are an important resource which are recurrent social spaces in different navigation paths complementing other activities

Ophiuroidea of the Avilés Canyons System (INDEMARES + LIFE Project).

The Avilés Canyons System (ACS) is located in the Cantabrian Sea (Bay of Biscay) and is composed of three canyons. It was declared Site of Community Importance (SCI: C ESZZ12003) within the Natura 2000 Network (Ministry of Agriculture, Food and Environment, 2014) due to their diversity of species and vulnerable habitats (Sánchez et.al., 2014). During the years 2010 - 2012 several campaigns of the INDEMARES LIFE - ACS project were carried out. This study includes the zone that goes from the beginning of the continental slope to the maximum depth sampled in the bathyal zone (depth range between 266 and 2291 m). A total of 7413 specimens which correspond to 48 species, were collected from 50 stations. The most abundant species were Ophiocten affinis (Lütken, 1858) with 4092 specimens and Ophiothamnus affinis Ljungman, 1872 with 1842. The most frequent ones were Ophiactis abyssicola (M. Sars, 1861) and Ophiacantha bidentata (Bruzelius, 1805) present in 48% and 26% of stations respectively. Comparing our species with public databases (OBIS, GBIF) and the bibliography, five potential new records have been found for the Cantabrian Sea, part of the North-Atlantic Marine Subdivision (Lavín et. al., 2012).Universidad de Málaga.

Estabilidad física de mezclas de aceite esencial de tomillo y un tensioactivo no iónico

El aceite esencial de tomillo es un componente natural con propiedades antioxidantes y antimicrobianas; propiedades que lo hacen muy interesante en campos como el alimentario, el cosmético o el agroalimentario. Los alquil polipentósidos son una nueva clase de tensioactivos derivados de recursos agrícolas renovables como paja de trigo. Son tensioactivos respetuosos con el medio ambiente, ya que muestran alta y rápida biodegradabilidad, así como baja toxicidad. En este trabajo se ha estudiado un alquil polipentósido comercialmente conocido como Appyclean 6548. Este tensioactivo no iónico es sólido a temperatura ambiente y soluble en disolventes orgánicos por lo que para ser usado como emulsionante de emulsiones ecológicas O/W es necesario fundirlo en la fase oleosa. Por este motivo, en esta investigación se estudia el efecto del tratamiento térmico al que es sometida una mezcla aceite esencial de tomillo/Appyclean 6548 en relación en peso 90,9/9,1, sobre su estabilidad física. Adicionalmente, se investiga la influencia de dicho tratamiento sobre la estabilidad física de emulsiones aceite esencial de tomillo/W obtenidas con una fase dispersa de concentración equivalente a la estudiada en la fase previa. Para abordar los objetivos planteados se han usado técnicas como la difracción láser y barridos de retrodispersión de luz.Thyme essential oil is a natural compound with antibacterial and antioxidant activity which are really interesting to be used as functional ingredient in food, cosmetics and agrochemical industries. Alkyl polypentosides are a new class of surfactants which coming from agricultural renewable resources as wheat straw. They are non-toxic and biodegradable surfactants commercially known as Appyclean. In this case, Applyclean 6548 was studied. This non-ionic surfactant is solid and it is immiscible in water so, the emulsifier was melted and dissolved in the oil phase. For this reason, the influence of thermal treatment was studied in a 90.9/9.1 mass ratio (thyme essential oil/Appyclean 6548) on physical stability of these dispersions. Additionally, this influence was investigated on the stability and droplet size distribution of thyme essential oil/W emulsions. In order to achieve this goal laser diffraction and multiple light scattering techniques were used.Plan Propio de la Universidad de Sevilla Proyecto: 2017/00000962Ministerio de Economía y Competitividad (España)/FEDER (UE) CTQ2015-70700-

Enfermedades psiquiátricas y trabajo. Revisión bibliográfica y jurisprudencial (Trastornos esquizofrénicos, trastorno bipolar y trastornos ansioso-depresivos)

Las enfermedades psiquiátricas en su conjunto y, algunas de ellas de forma específica, constituyen un problema de salud pública en todos los países y conllevan un coste económico asociado, tanto directo como indirecto. Pero además, cuando la persona enferma ejerce su derecho al trabajo ello comporta, en ocasiones, más allá de su diagnóstico y su tratamiento, la necesidad de tomar unas acciones en las empresas, limitantes adaptativas o restrictivas, para el trabajador afectado y la adopción de medidas socio-laborales con repercusión posterior administrativa y jurídica. Se revisarán en este trabajo las publicaciones médicas recogidas en la base de datos de referencia (Pub-Med) relativa a estas patologías, su diferenciación en cuanto a los aspectos clínico asistenciales y su comparativa con los socio-laborales. De igual forma se realiza en este trabajo una revisión del impacto de estas patologías en la base de datos jurídica (Westlaw Insignis) y su diferenciación según cada patología y área del derecho correspondiente. Sirvan los resultados para, a través del conocimiento actual de la situación, basada en estos datos, elaborar posibles estrategias preventivas de futuro ante conflictos médico legales y de nuevos enfoques más coordinados entre todos los agentes implicados.Psychiatric disorders as a whole and some of them in a specific way constitute a public health problem in all countries and entail an economic cost associated, both directly and indirectly. In addition, some issues are to be considered when the sick person exercises his right to work, beyond diagnosis and treatment of his/her disease. Companies need to take some actions whether adaptive or restrictive for the affected employee, and the adoption of socio-labor measures which will have administrative and legal impact. The medical publications listed in the reference database (Pub-Med) concerning these pathologies will be reviewed in this article with emphasis in those clinical aspects that correlate health care with socio-labor implications. Paralelly, this work reviews the impact of these diseases in the legal databases (Westlaw Insignis) and their differentiation according to each disorder and its corresponding area of the law.The conclusions of this work, through the current knowledge of the situation, will serve to develop possible preventive strategies to address future medico-legal conflicts as well as to develop more coordinated approaches among all the stakeholders

Oxidative stress status in an institutionalised elderly group after the intake of a phenolic-rich dessert

The present study was supported by a grant from Hero España S.A. M. C. R.-T. and J. L. Q. are recipients of a ‘Ramón y Cajal’ contract from the Ministry of Science and Technology and the University of Granada, Spain. We also thank the Fundacio´n Se´neca of the C.A.R.M. (Murcia, Spain) for the fellowship of J. G.-A.The elderly population undergoes a series of physiological and sociological changes common to old age with a high probability of suffering degenerative illness and malnutrition. A dessert rich in phenolic compounds has been designed by using concentrated juices of grape, cherry, blackberry, blackcurrant and raspberry with the aim of it being used as a complementary food in adulthood. In the present study, we investigated the effect of the intake of this dessert (a jar of 200 g daily for a period of 2 weeks), with an antioxidant activity equivalent to ten servings of fruits and vegetables, on several markers of oxidative and antioxidant status in DNA and plasma in a group of elderly individuals. Non-smoking institutionalised elderly subjects were recruited from a pool of volunteers in an old-age home in Murcia (Spain). Twenty-two subjects (six men and sixteen women) participated in the study. The study was designed as a randomised intervention trial with a period of 2 weeks. At days 1 and 15, blood samples were collected to analyse total antioxidant capacity, biochemical parameters, antioxidant vitamins, LDL peroxidation, and DNA damage in peripheral blood lymphocytes. The conclusion of the present study is that a 2-week intervention with our dessert enriched with natural polyphenol compounds in elderly individuals does not give enough time to find changes in the antioxidant and oxidative status. Also, the view that the marked antioxidant ability of polyphenols in vitro does not translate to analogous effects in vivo was confirmed. Moreover, a highly oxidative stress status during ageing was confirmed, together with the need to perform follow-up nutritional studies to improve this situation

Especias, hierbas medicinales y plantas. Usos en medicina. Revisión de la bibliografía científica (Medline)

Diversas hierbas, plantas y especias han sido importantes instrumentos de la medicina tradicional y, a veces, de la magia. Antes de la generalización de los medicamentos elaborados de forma industrial, solían prescribirse remedios compuestos por hierbas, muchos de ellos de probada eficacia, que han sido redescubiertos y utilizados en nuestros días. En la actualidad, la ciencia nos ofrece información contrastada sobre los efectos beneficiosos que las especias pueden suponer en determinadas patologías y las bondades médicas que se apuntan en el horizonte de la ciencia. Culturas orientales, como la India o la China, llevan años incorporando experiencias en esta línea de estudio. Se realiza en este trabajo una recopilación de algunas de estas publicaciones, dejando abierto el campo a futuros investigadores occidentales y especialmente españoles, sobre las opciones terapéuticas que ofrecen las especias y las plantas; un camino donde nuestra experiencia es aún escasa.Various herbs, plants and spices have been important tools for traditional medicine and sometimes magic. Before the widespread use of industrially manufactured drugs, very common remedies, made out of herbs were prescribed, many of them with proven efficacy that have been rediscovered and used nowadays. Today, science offers contrasted information on the beneficial effects that spices may represent for certain pathologies and their potential medical benefits that might arise in the horizon of science. Eastern cultures, such as India or China, spent years incorporating their experiences in this line of study. This work represents a compilation of some of these publications, leaving the field opened to future researchers, western and especially Spanish, on potential treatment options offered by spices and plants, a path where our experience is still limited
