Las empresas de inserción de Galicia. Un campo de intervención profesional para la educación social y la animación sociolaboral

Atès el seu nombre i la seva finalitat, i per a aportar un instrument més a la integració dels sectors exclosos, l’Estat espanyol va regular les empreses d’inserció a través de la Llei 44/2007, de 13 de desembre. La realització d’un TFG d’educació social ens vapermetre veure si són un instrument facilitador de la transició al treball i observar que, pel fet d’implicar la metodologia de l’animació sociolaboral, són un camp d’intervenciósocioeducativa per a l’educació social, si bé existeixen certes mancances pel que fa a la contextualització del paper i les funcions de l’educador/a social.On account of the number and purpose of the job integration agencies, and with a view to providing an additional impetus to the integration of disadvantaged sectors of society, the Spanish government passed Law 44/2007 of 13 December to regulate these firms. Our final-year degree project in Social Educationgave us an opportunity to see if they are an effective instrument in facilitating the transition to work and to observe that, when the methodology of socio-occupational animation is applied, they constitute a field of intervention for social education, despite the absence of certain aspects of contextualization of the roleand functions of the social educator.Debido a su número y a su finalidad, y para aportar un instrumento más a la integración de los sectores excluidos, el Estado españolreguló las empresas de inserción a través de la Ley 44/2007, de 13 de diciembre.

Accessibility of rail trails in Huelva, Andalusia (Spain)

The rail trails (converted disused railways) are infrastructures which can be reused mainly as non-motorised itineraries for hiking and cycle touring. Andalusia (Spain) has a network of 1442 km of disused railways, out of which 606 km are found in Huelva province (42.1%) as heritage from its former mining activity. The aim of this article is to devise a method which determines the real accessibility to rail trails and the volume of resident population who can reach them in a time period of 5, 10 and 15 minutes by road in a private vehicle. This process involves the determination of real accesses with accuracy and the differentiated calculation of the average speed on the different types of routes. The method is used for the three rail trails which currently exist in Huelva (98.6 km), having as a result a Map at a scale of 1:325,000

Integrin Signaling Regulates Spindle Orientation in Drosophila to Preserve the Follicular-Epithelium Monolayer

SummaryEpithelia act as important physiological barriers and as structural components of tissues and organs. In the Drosophila ovary, follicle cells envelop the germline cysts to form a monolayer epithelium. During division, the orientation of the mitotic spindle in follicle cells is such that both daughter cells remain within the same plane, and the simple structure of the follicular epithelium is thus preserved. Here we show that integrins, heterodimeric transmembrane receptors that connect the extracellular matrix to the cell's cytoskeleton [1, 2], are required for maintaining the ovarian monolayer epithelium in Drosophila. Mosaic egg chambers containing integrin mutant follicle cells develop stratified epithelia at both poles. This stratification is due neither to abnormal cell proliferation nor to defects in the apical-basal polarity of the mutant cells. Instead, integrin function is required for the correct orientation of the mitotic apparatus both in mutant cells and in their immediately adjacent wild-type neighbors. We further demonstrate that integrin-mediated signaling, rather than adhesion, is sufficient for maintaining the integrity of the follicular epithelium. The above data show that integrins are necessary for preserving the simple organization of a specialized epithelium and link integrin-mediated signaling to the correct orientation of the mitotic spindle in this epithelial cell type

Characteristics of strength and speed of execution in young women soccer players

El objetivo de este estudio fue caracterizar y comparar la fuerza máxima y rápida, la potencia anaeróbica, la velocidad de ejecución y de desplazamiento en función de la posición de juego en 59 jóvenes futbolistas distribuidas en dos categorías.

Luminescent microbial bioassays and microalgal biosensors as tools for environmental toxicity evaluation

This chapter deals with toxicity bioassays and biosensors based on luminescent microorganisms that report on global toxicity of a sample in such a way that luminescence is reduced or inhibited in the presence of toxic compounds that impair metabolism. Both natural as well as recombinant microorganisms are considered. A detailed description of their main characteristics and environmental applications is reported. A few examples of bioassays for detecting oxidative stress (both bioluminescent and fluorescent bioreporters) are also mentioned and discussed as reactive oxygen species (ROS) formation and subsequent oxidative stress if the antioxidant defenses of the cells are surpassed is one of the main mechanisms of toxicity for most pollutants. There is also a section dedicated to microalgal–based biosensors given their ecological relevance as primary producers, their easiness of culture and immobilization in different matrices, ability to acclimate to low nutrients conditions and ubiquity in aquatic environments. The most used toxicity endpoints for this type of biosensors are the alteration of photosynthetic activity (optical and amperometric biosensors) and the inhibition of enzymes such as alkaline phosphatase (APA) or sterases (mostly conductometric biosensors). The main information is shown in tables that include the microorganisms, their main characteristics (reporter gene systems, transducer types for biosensors) and their main environmental applications as well as relevant references. Although some of these bioassays have already been standardized by different international organizations, there are still many which are also promising tools for environmental global toxicity evaluation and should be fully validated and standardized for regulatory purposesThis research was supported by the Spanish Ministry of Economy and Competitiveness (MINECO), grant CTM2016-74927-C2-2-

Impact on human health of microorganisms present in fermented dairy products: An overview

Fermented dairy products provide nutrients in our diet, some of which are produced by the action of microorganisms during fermentation. These products can be populated by a diverse microbiota that impacts the organoleptic and physicochemical characteristics foods as well as human health. Acidification is carried out by starter lactic acid bacteria (LAB) whereas other LAB, moulds, and yeasts become dominant during ripening and contribute to the development of aroma and texture in dairy products. Probiotics are generally part of the nonstarter microbiota, and their use has been extended in recent years. Fermented dairy products can contain beneficial compounds, which are produced by the metabolic activity of their microbiota (vitamins, conjugated linoleic acid, bioactive peptides, and gamma-aminobutyric acid, among others). Some microorganisms can also release toxic compounds, the most notorious being biogenic amines and aflatoxins. Though generally considered safe, fermented dairy products can be contaminated by pathogens. If proliferation occurs during manufacture or storage, they can cause sporadic cases or outbreaks of disease. This paper provides an overview on the current state of different aspects of the research on microorganisms present in dairy products in the light of their positive or negative impact on human health. © 2015 María Fernández et al.The work at the Spanish author’s laboratories was mainly financed through the projects AGL2010-16525 and INIA RM2010-00017-00-00 from the Ministry of Economy and Competitiveness (Spain).Peer Reviewe

Immune modulating capability of two exopolysaccharide-producing bifidobacterium strains in a wistar rat model

Fermented dairy products are the usual carriers for the delivery of probiotics to humans, Bifidobacterium and Lactobacillus being the most frequently used bacteria. In this work, the strains Bifidobacterium animalis subsp. lactis IPLA R1 and Bifidobacterium longum IPLA E44 were tested for their capability to modulate immune response and the insulin-dependent glucose homeostasis using male Wistar rats fed with a standard diet. Three intervention groups were fed daily for 24 days with 10% skimmed milk, or with 109 cfu of the corresponding strain suspended in the same vehicle. A significant increase of the suppressor-regulatory TGF-β cytokine occurred with both strains in comparison with a control (no intervention) group of rats; the highest levels were reached in rats fed IPLA R1. This strain presented an immune protective profile, as it was able to reduce the production of the proinflammatory IL-6. Moreover, phosphorylated Akt kinase decreased in gastroctemius muscle of rats fed the strain IPLA R1, without affecting the glucose, insulin, and HOMA index in blood, or levels of Glut-4 located in the membrane of muscle and adipose tissue cells. Therefore, the strain B. animalis subsp. lactis IPLA R1 is a probiotic candidate to be tested in mild grade inflammation animal models. © 2014 Nuria Salazar et al.This work was financed by the Spanish Ministry of Economy and Competitiveness (MINECO) and the FEDER European Union funds through the projects AGL2010-16525 and AGL2012-33278.

Effect of an α-Tocopherol-Containing Antioxidant Parenteral Emulsion upon Gut Microbiota in Preterm Infants

Preterm babies are born with an immature intestine and are at higher risk for intestinal failure and needing for parenteral nutrition than full-term newborns. These babies show an altered intestinal microbiota, which may results of key importance for later health. However, there is a lack of information on effect of parenteral formulas upon the establishing infant microbiota. Moreover, the microbiota alterations present in preterm newborns have been related with an altered redox-potential which hinders the establishment of strict anaerobes. Thus, interventions aimed at reducing the oxidative stress in these infants, including those under parenteral nutrition, could also affect the intestinal microbiota composition. We assessed the effect upon the gut microbiota of the administration during 30 days of a lipid emulsion, containing ω3 polyunsaturated fatty acids and α-tocopherol, or a control emulsion containing soybean-bases lipids to parenterally-fed preterm newborns. In spite of its high antioxidant potential, the infants receiving the experimental fat emulsion showed a trend to increase of facultative anaerobes such as enterobacteria and specifically of Klebsiella. This study stresses the need of further work monitoring the impact of early-life parenteral nutrition on the establishment of the intestinal microbiota.This work was funded by the Luis Noé Fernández Award from Fundación Alimerka (Spain).Peer Reviewe
