Enhanced In Situ Availability of Aphanizomenon Flos-Aquae Constituents Entrapped in Buccal Films for the Treatment of Oxidative Stress-Related Oral D…
2019
In recent years, the key role of oxidative stress in pathogenesis of oral diseases has been emphasized and the use of antioxidant agents has been encouraged. Aphanizomenon flos-aquae (AFA) is a unicellular blue-green alga with antioxidant and anti-inflammatory properties. The aim of this study was the formulation and characterization of mucoadhesive thin layer films loaded with AFA, finalized to the treatment of oxidative stress (OS)-related oral diseases. First, to enhance the bioavailability of AFA constituents, the raw food grade material was appropriately treated by a high frequency homogenization able to disrupt cell walls. Thus, Eudragit®
Elaboración y validación biomecánica de un guante de protección para jugar a pelota valenciana. (Elaboration and biomechanical validation of a protec…

ResumenLa pelota valenciana es uno de los antiguos juegos de pelota a mano que perdura en la Comunidad Valenciana. Para amortiguar los impactos de la pelota durante el golpeo, los jugadores se confeccionan sus propias protecciones. En torno a ellas existen diversos factores que dificultan la práctica segura y eficaz de este deporte: el excesivo tiempo empleado en su elaboración, el elevado número de lesiones que sufren en las manos o el inadecuado control de la pelota que consiguen. En base a esto y a la inexistencia de un equipamiento deportivo específico para la mano, se ha desarrollado y validado un guante para intentar solventar estos inconvenientes. En la validación biomecánica se comp…
Influence of formalin fixation on the biomechanical properties of human diaphyseal bone.
2010
Owing to the lack of fresh human bones, formalin-fixed specimens are frequently used in biomechanical testing. However, formalin fixation is assumed to affect the biomechanical properties of bone. The aim of this study was to compare axial and torsional stiffness and bone mineral density in fresh and embalmed human bones. The subtrochanteric regions of 12 pairs of fresh human femora were randomised into two groups for paired comparison. After bone mineral density measurement, one group was preserved in 4% formalin. After 6 weeks, bone mineral density was remeasured and each specimen underwent axial and torsional loading. The formalin group showed significant higher stiffness values for tors…
Hereditariness of Aortic Tissue: In-Vitro Time-Dependent Failure of Human and Porcine Specimens
2018
This study aims to investigate the time dependent failure of aortic tissues for pathological and healthy samples by biomechanical testing. The experimental campaign has involved human pathological tissue and healthy swine tissue as preliminary study towards the development of novel failure criteria.
