Tissue Engineering Biopolymers

2011

Tissue engineering has always been a multidisciplinary research area focused on tissue regeneration and restoration of organs function, through implantation of cells or tissues growing outside the body. According to increase in knowledge of the interactions between living organisms and biomaterials, development and diversification of biocompatible devices has brought the world of medicine to what has been the greatest therapeutic revolution of our times. The main challenge of biomaterials is not only related to "tolerance-biocompatibility" by the body but also in its functionality. A biomaterial must be able to positively interact with tissues and exercise those functions for which it was d…

"Hoc opus fodit Pirus Martini de Pisis". Note su un capolavoro di oreficeria toscana con smalti del XIV secolo a Geraci Siculo

2012

Il prezioso ostensorio, trasformato in reliquiario nel XVII secolo, conservato nel tesoro della Chiesa Madre di Geraci Siculo (PA), è già noto da tempo agli studiosi perché firmato dall'orafo pisano Piro di Martino (lettura dell'iscrizione corretta, piuttosto che "Pino di Sammartino"). Il saggio, che per la prima volta ne descrive gli smalti traslucidi, propone una datazione alla seconda metà del XIV secolo per ragioni stilistiche e ne attribuisce la committenza al conte Francesco II Ventimiglia. The precious monstrance, transformed into a reliquary in the 17th century, kept in the treasury of the Mother Church of Geraci Siculo (PA), has long been known to scholars because it was signed by …

Broglie and Young, visionaries who shed light in the polar topology that grounds our reality: a hypothesis

2020

Una observación matemática que relaciona los patrones fractales y la operación de convolución en el contexto del procesamiento de imágenes digitales interrumpió una investigación que nos lleva a plantear la hipótesis de que el concepto de onda de materia (o dualidad onda-partícula) se encuentra en la dicotomía entre el par débil y un topología fuerte en el ámbito del marco de atractores singulares continuos en ninguna parte diferenciables y el concepto de fotón-solitón de Vigier. Tal inferencia parece ser más evidente en la interpretación de Broglie-Bohm de la mecánica cuántica en el cruce de características locales x globales. De esto se deduce también que la relación de los fenómenos natu…

Sterilization of three-dimensional tissue engineering scaffolds by supercritical carbon dioxide

2014

Medical devices, implants or patient-care equipment that will come into intimate contact with a patient must be effectively decontaminated to prevent infection or disease transmission. Non-sterile devices have significant ramifications for patient morbidity and mortality and two processes must be undertaken in order to make an item acceptable for use or implantation: cleaning and disinfection (or sterilization) [1]. Sterilization is the destruction of living organisms, and must be done without damaging the material surface and without compromising the bulk material strength or biocompatibility of implantable device. Common sterilization processes include steam autoclaving, gamma irradiation…

On Stability of a Concentrated Fiber Suspension Flow

2014

Linear stability analysis of a fiber suspension flow in a channel domain is performed using a modified Folgar-Tucker equation. Two kinds of potential instability are identified: one is associated with overcritical Reynolds number and another is associated with certain perturbations in fiber orientation field and is present for any Reynolds numbers. The second type of instability leads to initially growing transient perturbations in the microstructure. It is shown that both types of instability lead to instability of the bulk velocity field. As for the perturbed Orr-Sommerfeld eigenvalues, the presence of fibers increases the stability region; the stability region increases with growing C i …
