Medium-Term Culture of Primary Oral Squamous Cell Carcinoma in a Three-Dimensional Model: Effects on Cell Survival Following Topical 5-Fluororacile D…
2012
Since the activity of several conventional anticancer drugs is restricted by resistance mechanisms and dose-limiting side-effects, the design of formulations for local application on malignant lesions seems to be an efficient and promising drug delivery approach. In this study, the effect of locally applied 5-FU on cell death was evaluated both in a SCC4/HEK001 model and in a newly proposed 3D outgrowth model of oral squamous cell carcinoma (OSCC). Initially, the optimal drug dose was established by delivery of solutions containing different amounts of 5-FU. The solution containing 1% (w/v) of 5-FU resulted effective in inducing cell death with complete eradication of cell colonies. Buccal …
A 3D‑scaffold of PLLA induces the morphological differentiation and migration of primary astrocytes and promotes the production of extracellular vesi…
2019
The present study analyzed the ability of primary rat astrocytes to colonize a porous scaffold, mimicking the reticular structure of the brain parenchyma extracellular matrix, as well as their ability to grow, survive and differentiate on the scaffold. Scaffolds were prepared using poly-L-lactic acid (PLLA) via thermally-induced phase separation. Firstly, the present study studied the effects of scaffold morphology on the growth of astrocytes, evaluating their capability to colonize. Specifically, two different morphologies were tested, which were obtained by changing the polymer concentration in the starting solution. The structures were characterized by scanning electron microscopy, and a…
Proyecciones convergentes sobre el núcleo incertus en rata
2016
En un organismo animal, tanto la información procedente del entorno como la que proviene del medio interno ha de ser procesada, interpretada y almacenada mediante conexiones entre las distintas áreas del sistema nervioso central. Los centros superiores son los encargados del análisis y almacenamiento en forma de memoria de esta información. Estos centros superiores a su vez reciben proyecciones de núcleos subcorticales, cuya función, es la modulación de estos centros.En este trabajo ademas también proponemos la existencia de proyecciones desde los centros superiores hasta los núcleos subcorticales, generandose así un circuito tanto ascendente como descendente de la información.

ANP and vasopressin -presence in the ciliary body of eye in the pig, (Sus domesticus)
2014
The aqueous humor is produced in the ciliary body so, in this study we investigate on the ANP presence and vasopressin in the ciliary body of the pig eye since these peptide are involved in the homeostasis of the body fluids. The results show ANP-presence in the epithelial cells and in the endothelial cells of the blood vessels and VP-presence in the epithelial cells, in the endothelium of canal of Schelmm and in the muscle cells of the blood vessels. These peptides might regulate the synthesis and the composition of the aqueous humor and regulate the hydrodynamic flow and haemodynamic flow of the blood.
