Innovación en las enseñanzas universitarias: experiencias presentadas en las III Jornadas de Innovación Educativa de la ULL

En este libro se recoge un conjunto de experiencias de innovación educativa desarrolladas en la ULL en el curso 2011-12. Se abordan distintos ámbitos y ramas del conocimiento, y ocupan temáticas variadas que han sido desarrolladas con rigor, y con un claro potencial para su extrapolación a efectos de la mejora educativa en el ámbito universitario. Esta publicación constituye una primera edición de una serie que irá recogiendo las experiencias de innovación educativa de la ULL. Este es un paso relevante para su impulso en nuestra institución, como lo es el de su vinculación con la investigación educativa, para potenciar su publicación en las revistas científicas en este ámbito cada vez más pujante y relevante para las universidades. Sobre todo representan el deseo y el compromiso del profesorado de la ULL para la mejora del proceso educativo mediante la investigación, la evaluación y la reflexión compartida de nuestras prácticas y planteamientos docentes

Human Exposure to Toxic Metals (Cd, Pb, Hg) and Nitrates (NO3−) from Seaweed Consumption

Seaweed is now considered a functional food with a high nutritional value in Western countries, and the consumption of different species of edible algae has grown exponentially in recent decades. However, anthropogenic pressure on the seas has increased the presence of pollutants such as toxic metals and nitrates that can accumulate in algae. It is necessary to know the levels of these contaminants and the dietary exposure from the consumption of edible algae. The content of toxic metals (Cd, Pb, Hg) and nitrates (NO3−) was determined in 72 samples of edible algae marketed in the Canary Islands (Spain). Cd stands out in the Asian algae hijiki (1.196 mg/kg) and nori (1.005 mg/kg). Pb stands out in the Asian wakame seaweed (0.119 mg/kg). The highest mean concentration of Hg was in European arame algae (0.055 mg/kg). Some samples of the nori seaweed had NO3− concentrations of >8000 mg/kg. Considering the consumption recommended by the manufacturer of 4 g/day, the maximum admissible intake values are not exceeded, and, consequently, this does not pose a risk to health. However, in the case of Cd, Pb, Hg, and NO3−, legislation is necessary to regulate their content in edible algae

Considerations on diagnosis and surveillance measures of PTEN hamartoma tumor syndrome : clinical and genetic study in a series of Spanish patients

Altres ajuts: European Regional Development Fund; Federación Española de Enfermedades Raras (FEDER); European Social Fund (ESF).Background: The limited knowledge about the PTEN hamartoma tumor syndrome (PHTS) makes its diagnosis a challenging task. We aimed to define the clinical and genetic characteristics of this syndrome in the Spanish population and to identify new genes potentially associated with the disease. Results: We reviewed the clinical data collected through a specific questionnaire in a series of 145 Spanish patients with a phenotypic features compatible with PHTS and performed molecular characterization through several approaches including next generation sequencing and whole exome sequencing (WES). Macrocephaly, mucocutaneous lesions, gastrointestinal polyposis and obesity are prevalent phenotypic features in PHTS and help predict the presence of a PTEN germline variant in our population. We also find that PHTS patients are at risk to develop cancer in childhood or adolescence. Furthermore, we observe a high frequency of variants in exon 1 of PTEN, which are associated with renal cancer and overexpression of KLLN and PTEN. Moreover, WES revealed variants in genes like NEDD4 that merit further research. Conclusions: This study expands previously reported findings in other PHTS population studies and makes new contributions regarding clinical and molecular aspects of PHTS, which are useful for translation to the clinic and for new research lines
