Impact of an educational hands-on project on the antimicrobial, antitumor and anti-inflammatory properties of plants on Portuguese students' awareness, knowledge, and competences

Promoting environmental and health education is crucial to allow students to make conscious decisions based on scientific criteria. The study is based on the outcomes of an Educational Project implemented with Portuguese students and consisted of several activities, exploring pre-existent Scientific Gardens at the School, aiming to investigate the antibacterial, antitumor and anti-inflammatory properties of plant extracts, with posterior incorporation in soaps and creams. A logo and a webpage were also created. The effectiveness of the project was assessed via the application of a questionnaire (pre- and post-test) and observations of the participants in terms of engagement and interaction with all individuals involved in the project. This project increased the knowledge about autochthonous plants and the potential medical properties of the corresponding plant extracts and increased the awareness about the correct design of scientific experiments and the importance of the use of experimental models of disease. The students regarded their experiences as exciting and valuable and believed that the project helped to improve their understanding and increase their interest in these subjects and in science in general. This study emphasizes the importance of raising students’ awareness on the valorization of autochthonous plants and exploitation of their medicinal properties.

Concepts and objects of awareness in Alzheimer’s disease: an updated systematic review

ABSTRACT Objectives To compare and discuss the objects of awareness in Alzheimer’s disease (AD): awareness of cognitive deficits, of functional activities, of social-emotional functioning and behavioral impairment. Methods A search in the PsycINFo, Pilots, PubMed/Medline and ISI electronic databases according to Prisma methodology was performed. We included studies about awareness in people with AD published between 2010 and 2015, with the combination of keywords: “Alzheimer AND awareness of deficits”, “Alzheimer AND anosognosia”, “Alzheimer AND insight”, “dementia AND awareness of deficits”, “dementia AND anosognosia”, “dementia AND insight”. The articles were categorized according to the specific object of awareness. Results Seven hundred and ten records were identified and, after application of the exclusion criteria, 191 studies were retrieved for potential use. After excluding the duplicates, 46 studies were included. Most studies assessed the cognitive domain of awareness, followed by the functional, social-emotional, and behavioral impairment domains. Memory deficits were not sufficient to explain impaired awareness in AD. Longitudinal studies did not find discrepancies between patients and caregivers’ reports, indicating that awareness is not related to cognition. Conflicting findings were observed, including the relation between awareness, mood, severity of disease, and personal characteristics. Conclusions The studies show lack of conceptual consensus and significant methodological differences. The inclusion of samples without differentiation of dementia etiology is associated to symptomatic differences, which affect awareness domains. Awareness in AD is a complex and multidimensional construct. Different objects elicit different levels of awareness.

Current situation on the occurrence of mycotoxins and toxigenic fungi in Portugal

Mycotoxins are secondary metabolites produced by filamentous fungi that are toxic for humans and animals in small amounts and that are found worldwide in a large number of agricultural commodities. They are usually ingested involuntarily, when contaminated plant products are consumed, and represent a great risk for public health. Therefore, governments throughout the world have imposed strict legal limits for their levels in food and feed products in order to reduce potential health risks for consumers. Despite of its ubiquity, the mycotoxin problem is mainly dependent on regional factors, such as the mycotoxigenic characteristics of the local mycoflora, the local climate conditions, and the local agricultural practices. For this reason, a constant vigilance from local governmental food safety agencies and from the local researcher community is needed. This communication will review the current situation on the occurrence of mycotoxigenic fungi in some Portuguese cultures, such as wine grapes, corn and dried fruits. Particular attention will be given to the incidence of mycotoxigenic Aspergillus strains in those cultures and to the levels of ochratoxin A, aflatoxins, cyclopiazonic acid and fumonisin B2 produced. Data will be discussed taking into account the geographical origin of the isolates and the particular climate conditions of each sampling region. An updated review on the levels of the main mycotoxins found in local products and in imported commodities will also be presented.

Micro-empresa y capacidad empresarial en Córdoba: situación actual y perspectivas. Microenterprise and entrepreneurship in Córdoba: present situation and perpectives.

Las transformaciones del mercado laboral, tanto de los países desarrollados como en vías de desarrollo, han sido importantes en las últimas décadas. Una de sus manifestaciones es la creciente expansión del trabajo organizado en torno a los micro-emprendimientos. Las investigaciones existentes a nivel internacional indican que la capacidad empresarial que debe poseer el emprendedor es un factor que resulta crucial para el desarrollo y sostenimiento de estas formas de producción. Por tal razón, el estudio de este aspecto y de su relación con los micro-emprendimientos es un tema que está concitando creciente atención y sobre el que existe un cuerpo teórico de literatura específica que ha comenzado a transferirse a los países en vías de desarrollo, donde la discusión es aún incipiente. Los estudios han observado que los micro-emprendimientos están normalmente muy ligados a la familia, esto hace que su desenvolvimiento y evolución resulten afectados por las características particulares de cada hogar. Se trata de un complejo conjunto de situaciones sociales que se generan a partir de estas nuevas formas de organización del trabajo, donde resulta dificultoso distinguir entre el micro-emprendimiento y la figura del emprendedor, lo cual ha llevado a que muchas veces las políticas públicas, sensibles a la necesidad de apoyar a los grupos poblacionales vulnerables, adquirieran un sesgo pro-pobre, en detrimento de su objetivo principal de incentivar el desarrollo sustentable de pequeñas unidades productivas. El equipo de investigación autor del presente proyecto concluyó recientemente, en el marco de un proyecto PICTOR II, un primer estudio sobre la temática de los micro-emprendimientos en Córdoba, analizando los factores que ayudan a comprender mejor las razones por las que algunos emprendedores alcanzan un mayor éxito que otros, a partir del cual surgieron nuevos interrogantes sobre el rol de la política pública en esta materia, a los que se intentará dar respuesta en esta oportunidad. Más concretamente, en esta investigación se abordarán, ahora con profundidad, diversas cuestiones importantes que analizan el vínculo entre la figura del emprendedor con el micro-emprendimiento que posee y con el efecto general de las políticas públicas en el sector. Uno de los temas es determinar hasta qué punto el comentado sesgo "pro-pobre" estuvo presente en el caso de las políticas públicas aplicadas en Córdoba y qué consecuencias tuvo sobre los micro-emprendimientos y su sustentabilidad. Este aspecto está directamente ligado a la necesidad de discernir acerca de si el fundamento teórico de las políticas públicas diferencia adecuadamente entre el micro-emprendedor y la micro-empresa. Otra importante cuestión a abordar es la de indagar sobre la relación entre capacidad empresarial, capital humano y nivel socio-económico del emprendedor. Resultará de sumo interés identificar los factores que estimulan e inhiben las manifestaciones de capacidad empresarial individual, y establecer su relación con las posibilidades de sustentabilidad del micro-emprendimiento, lo cual debería ser tomado en cuenta por las políticas públicas. El caso de los individuos que se convirtieron en micro-emprendedores como una estrategia para superar la situación de desempleo en que se encontraban, es un tema que será examinado en especial y a la luz de la performance observada del emprendimiento. Serán fuentes primarias de información la Encuesta llevada a cabo en el proyecto PICTOR II arriba mencionado y una re-encuesta a los micro-emprendedores que fueron oportunamente entrevistados. A ello se agregará un estudio de casos de emprendimientos muy exitosos. Los datos de fuentes secundarias surgirán del INDEC, de organismos oficiales y de instituciones no gubernamentales. Los principales métodos y herramientas de análisis a utilizar son los que proporcionan la Estadística, la Econometría y la Micro-economía.

Analysis of energy management in GMIT

Energy management is the process of monitoring, controlling and conserving energy in a building or organisation. The main reasons for this are for cost purposes and benefit to the environment. Through various techniques and solutions for lighting, heating, office equipment, the building fabric etc along with a change in people’s attitudes there can be a substantial saving in the amount spent on energy. A good example o f energy waste in GMIT is the lighting situation in the library. All the lights are switched on all day on even in places where that is adequate daylighting, which is a big waste o f energy. Also the lights for book shelves are left on. Surely all these books won’t be searched for all at the one time. It would make much more sense to have local switches that the users can control when they are searching for a particular book. Heating controls for the older parts o f the college are badly needed. A room like 834 needs a TRV to prevent it from overheating as temperatures often reach the high twenties due to the heat from the radiators, computers, solar gains and heat from users o f the room. Also in the old part o f the college it is missing vital insulation, along with not being air tight due to the era when it was built. Pumped bonded bead insulation and sealant around services and gaps can greatly improve the thermal performance o f the building and help achieve a higher BER cert. GMIT should also look at the possibility o f installing a CHP plant to meet the base heating loads. It would meet the requirement o f running 4500 hours a year and would receive some financial support from the Accelerated Capital Allowance. I f people’s attitudes are changed through energy awareness campaigns and a few changes made for more energy efficient equipment, substantial savings can be made in the energy expenditure.

Efficiency and environmental regulation: a 'complex situation'

Production of desirable outputs is often accompanied by undesirable by products that have damaging effects on the environment, and whose disposal is frequently regulated by public authorities. In this paper, we compute directional technology distance functions under particular assumptions concerning disposability of bads in order to test for the existence of what we call ‘complex situations’, where the biggest producer is not the greatest polluter. Furthermore, we show that how in such situations, environmental regulation could achieve an effective reduction in the aggregate level of bad outputs without reducing the production of good outputs. Finally, we illustrate our methodology with an empirical application to a sample of Spanish tile ceramic producers.

Orientation of the snail Biomphalaria straminea (Dunker, 1848) in response to light in a situation of selection

The behavioral response of Biomphalaria straminea to light was evaluted in terms of location of the snail in a Y-shaped aquarium in a situation of selection and of the rate (cm/hour) and direction of locomotion under homogeneous 9vertical) or differential (horizontal) lighting upon only one arm of the aquarium. The light source consisted of daylight fluorescent lamps with a spectrum close to that of natural light, with illumination varying from 28 to 350 lux. Analysis of the data showed that all animals, whether in groups or isolated, were attracted to light, although the time needed to approach the light source was 50% shorter for the former than for the latter. The rate of locomotion of B. straminea was 35% higher than observed in B. glabrata and 51% higher than that observed in B. tenagophila studied under similar conditions. The results are discussed in terms of social factors and geographical distribution of the three species.
