A Fermented Food Product Containing Lactic Acid Bacteria Protects ZDF Rats from the Development of Type 2 Diabetes

Type 2 diabetes (T2D) is a complex metabolic disease, which involves a maintained hyperglycemia due to the development of an insulin resistance process. Among multiple risk factors, host intestinal microbiota has received increasing attention in T2D etiology and progression. In the present study, we have explored the effect of long-term supplementation with a non-dairy fermented food product (FFP) in Zucker Diabetic and Fatty (ZDF) rats T2D model. The supplementation with FFP induced an improvement in glucose homeostasis according to the results obtained from fasting blood glucose levels, glucose tolerance test, and pancreatic function. Importantly, a significantly reduced intestinal glucose absorption was found in the FFP-treated rats. Supplemented animals also showed a greater survival suggesting a better health status as a result of the FFP intake. Some dissimilarities have been observed in the gut microbiota population between control and FFP-treated rats, and interestingly a tendency for better cardiometabolic markers values was appreciated in this group. However, no significant differences were observed in body weight, body composition, or food intake between groups. These findings suggest that FFP induced gut microbiota modifications in ZDF rats that improved glucose metabolism and protected from T2D development

The impact of campus bullying on EEGAFI senior high school students’ academic performance

This study describes and analyzes the campus bullying experiences of senior high school students, their problems encountered, their emotional struggles, their coping strategies and even their insights and realizations that would be useful in making interventions in the future. Questions were given to scrutinize their experiences through Google forms platform which they have to choose an option from the Likert scale correspondingly. Findings from this study lead to a better understanding of campus bullying, encouraging school administrators, guidance consultants, class advisers, and subject teachers to develop policies to address the phenomenon of school bullying. Responding to bullying respectfully increases student motivation to learn and ultimately improves academic performance

Modificación de un material didáctico interactivo en la búsqueda de un aprendizaje más adaptativo

Este trabajo presenta la evolución de un material didáctico interactivo orientado hacia el sistema de especificaciones geométricas de productos, ISO GPS. El grupo de Innovación Educativa Ingeniería de Fabricación de la Universidad de Las Palmas de Gran Canaria ha buscado aportar un grado de adaptatividad más alto a este material implementándolo directamente en la plataforma Moodle. Se han reorganizado los contenidos en varios bloques para mejorar su progresividad, siendo necesario superar cuestionarios de conceptos básicos para ir avanzando hacia nuevos contenidos. También se le han incorporado nuevos recursos como videos interactivos de resolución de problemas y un simulador gráfico para la visualización de las tolerancias y ajustes. Se ha empleado metodologías con la participación activa y colaborativa de estudiantes, tanto para el desarrollo como en la evaluación de este nuevo material didáctico. Los resultados obtenidos evidencian que las mejoras introducidas han tenido un impacto positivo en el aprendizaje en los estudiantes, y se ha mostrado también como una herramienta muy adecuada para su uso en una modalidad de educación híbrida que integre la docencia presencial y la telemática

Incorporation of calcium in glasses: a key to understand the vitrification of sewage sludge

The quantity of sewage sludge generated daily by wastewater treatment plants represents a major environmental problem and a financial burden for plant operators. Valorization strategies focusing on reusing sewage sludge as a raw material are currently developed. Vitrification can help us reduce the volume of waste and binds the components in the structure of chemically stable glasses and glass‐ceramics. In this study, the vitrification of sewage sludge inside a basaltic rock has been simulated by producing glasses and a glass‐ceramic from basalt enriched in calcium that lie between the stability fields of pyroxene and melilite in the system CaO‐MgO‐SiO2‐Al2O3. CaO addition causes the oxidation of the melt at above the liquidus, increases the crystallization temperature, decreases the melting temperature and improves the microhardness of the glasses Glass‐ceramic processes improves the properties of the Ca‐doped basalt glass. The microhardness of the glass (8.2 GPa) and the glass‐ceramic (8.6 GPa) and leaching tests (in the ppb range) place both the glass and the glass‐ceramics at the high end of the mechanical properties and chemical resistance of ceramic tiles for the building industry

Spain

This chapter presents a review of the situation concerning the various geomorphological hazards in the country, including some information about existing programmes for research, control and mitigation. With its great variety of climatic, geological and morphodynamic environments, Spain is subject to every kind of natural hazard: tsunamis, floods, volcanism, and mass movements. The whole of the territory is prone to some kind of geomorphological hazard but it is in the eastern and southern coastal strips that the risks are greatest. One of the main problems for the mitigation of geomorphological hazards in Spain is the lack of an appropriate regulatory framework for the incorporation of natural hazard assessments into land-use planning and management at the macro-, meso- and micro-planning levels. The coverage of hazard mapping is still far from complete or adequate, and much work remains to be done. There has been considerable diversity in the methods used for risk assessment and for the cartographic representation of natural hazards. An urgent need is to establish common, accepted methodologies and criteria, based on indicators defined as clearly as possible, and to standardize map legends and scales for different planning levels. Information programmes for the general public also need to be considerably expanded

MAPC transplantation confers a more durable benefit than AC133+ cell transplantation

There is a need for comparative studies to determine which cell types are better candidates to remedy ischemia. Here, we compared human AC133+ cells and Multipotent Adult Progenitor Cells (hMAPC) in a mouse model reminiscent of critical limb ischemia. hMAPC or hAC133+ cell transplantation induced a significant improvement in tissue perfusion (measured by microPET) 15 days post-transplantation compared to controls. This improvement persisted for 30 days in hMAPC-treated but not in hAC133+-injected animals. While transplantation of hAC133+ cells promoted capillary growth, hMAPC transplantation also induced collateral expansion, decreased muscle necrosis/fibrosis and improved muscle regeneration. Incorporation of differentiated hAC133+ or hMAPC progeny into new vessels was limited, however, a paracrine angio/arteriogenic effect was demonstrated in animals treated with hMAPC. Accordingly, hMAPC-, but not hAC133+-conditioned media, stimulated vascular cell proliferation and prevented myoblast, endothelial and smooth muscle cell apoptosis in vitro. Our study suggests that although hAC133+ cell and hMAPC transplantation bothcontribute to vascular regeneration in ischemic limbs, hMAPC exert a more robust effect through trophic mechanisms, which translated into collateral and muscle fiber regeneration. This, in turn, conferred tissue protection and regeneration with longer-term functional improvement
