Safety of Dietary Guanidinoacetic Acid: A Villain of a Good Guy?
2021
Guanidinoacetic acid (GAA) is a natural amino acid derivative that is well-recognized for its central role in the biosynthesis of creatine, an essential compound involved in cellular energy metabolism. GAA (also known as glycocyamine or betacyamine) has been investigated as an energy-boosting dietary supplement in humans for more than 70 years. GAA is suggested to effectively increase low levels of tissue creatine and improve clinical features of cardiometabolic and neurological diseases, with GAA often outcompeting traditional bioenergetics agents in maintaining ATP status during stress. This perhaps happens due to a favorable delivery of GAA through specific membrane transporters (such as…
DNA-based applications in molecular electronics
2011
This thesis is mainly focused on DNA molecules and especially on self-assembled DNA constructs and their potential applications in nanotechnology and molecular electronics. In the field of molecular electronics the conductivity of DNA is a crucial - yet open - question, and it is of great concern, since DNA is a very promising molecule in a context of bottom-up based nanodevices due to its superior selfassembly characteristics. A key tool in all the experiments presented in this thesis is a dielectrophoretic trapping technique, which was exploited in spatial manipulation of individualDNA molecules, DNA constructs and also semiconducting quantum dots. In the case of DNA, the technique provid…
Nanodevices by DNA based gold nanostructures
2017
In this thesis DNA based structures were utilized to create gold nanostructures for nanosensing and nanoelectronic applications. In the past, both of these fields have been dominated by the conventional lithography methods, e.g., electron beam lithography and UV-lithography, but more recently scaling down the components by these techniques has become increasingly more complex and costly. Especially in the micro- and nanoelectronics, the increase in the component density and thus computational power would require fabrication of sub-10-nm components, which is challenging for the top-down approaches. Aforementioned developments have led researchers to seek alternative methods to fabricate these…
Sarcopenia and appendicular muscle mass as predictors of impaired fasting glucose/type 2 diabetes in elderly women
2021
Elderly women exhibit a high risk of type 2 diabetes (T2D), but no definitive data exist about the possible role of postmenopausal increases in visceral adiposity, the loss of lean body mass, or decreases in the sum of the lean mass of arms and legs (appendicular skeletal muscle mass (ASMM)). This retrospective, longitudinal study investigated whether body composition (bioelectrical impedance analysis) predicted the development of impaired fasting glucose (IFG) or T2D in a cohort of 159 elderly women (age: 71 ± 5 years, follow-up: 94 months) from southern Italy (Clinical Nutrition and Geriatric Units of the “Mater Domini” University Hospital in Catanzaro, Calabria region, and the “P. Giacco…
Una aproximación empírica a través de las relaciones Ciencia-Tecnología- Sociedad (CTS, en estudiantes de secundaria y universitarios valencianos
1995
Resumen basado en el de la publicación Resumen en inglés Se revelan las perspectivas sobre la Ciencia-Tecnología-Sociedad (STS) de estudiantes de secundaria y estudiantes universitarios. El inventario VOSTS (Aikenhead et al., 1989) se utilizó para reflejar las creencias, posiciones y alfabetización de CTS. Llos resultados apuntan a la necesidad de introducir nuevos conceptos y actitudes, enfatizando la epistemología,la información y la cognición. ESP
Food-Based Dietary Guidelines around the World: A Comparative Analysis to Update AESAN Scientific Committee Dietary Recommendations
2021
Food-Based Dietary Guidelines (FBDG) include dietary recommendations based on food groups according to the general and accepted nutrition principles and current scientific evidence. Adoption of FBDG contributes to the prevention of malnutrition in all its forms, promotes human health, and reduces environmental impact. The present review aims to perform an international comparative analysis of the FBDG adopted in different countries from three different continents (America, Asia, and Europe), with particular reference to the Spanish Food Safety and Nutrition Agency (AESAN, Agencia Española de Seguridad Alimentaria y Nutrición) Scientific Committee dietary recommendations. A total of twelve c…
Scientific opinion on an application by Dow AgroSciences LLC (EFSA-GMO-NL-2012-106) for the placing on the market of genetically modified herbicide-t…
2017
Abstract Soybean DAS‐44406‐6 expresses 5‐enolpyruvyl‐shikimate‐3‐phosphate synthase (2mEPSPS), conferring tolerance to glyphosate‐based herbicides, aryloxyalkanoate dioxygenase (AAD‐12), conferring tolerance to 2,4‐dichlorophenoxyacetic acid (2,4‐D) and other related phenoxy herbicides, and phosphinothricin acetyl transferase (PAT), conferring tolerance to glufosinate ammonium‐based herbicides. The molecular characterisation data and bioinformatics analyses did not identify issues requiring assessment for food/feed safety. The agronomic and phenotypic characteristics revealed no relevant differences between soybean DAS‐44406‐6 and its conventional counterpart, except for pod count, seed cou…

Dones batxilleres als anys 60. Entre el conservadorisme i la modernitat
2015
La histórica exclusió de les dones de l'ambit públic ha comportat que reberen una educació que les ha allunyades del poder economic,polític i social. No sols la Universitat, sinó fins i tot els estudis de Batxillerat, destinat s a formar l'elit de la societat, els han estat vetats. Després del parèntesi republicà, no seria fins els anys 60 quan les dones iniciarien una important incorporació als estudis de Batxillerat, fet al que contribuirien la creació de centres públics, pràcticament paralitzats durant trenta anys. Seria l'Institut José Segrelles d'Albaida el primer institut que es crearia des dels anys republicans a les comarques valencianes i afavoria, en els primers 60, que les dones …
Educación y biblioteca : revista de documentación y recursos didácticos
2011
Resumen basado en el de la publicación Se presentan los problemas que plantea el fomento del hábito lector en Educación Secundaria y Bachillerato. Se parte desde la enseñanza de la literatura como promotora de un hábito lector entre los jóvenes. El docente debe distinguir entre lo que supone la enseñanza de la literatura y el fomento del hábito lector. Se plantean actividades previas, durante y posteriores a la lectura que ayudan a crear y mantener la costumbre de leer. Se concluye que se debe encontrar un equilibrio entre la enseñanza tradicional de la literatura y la moderna educación literaria que influyan en la creación del hábito lector. Madrid Biblioteca de Educación del Ministerio de…
