Journal ArticleDOI
A review on cyclodextrin encapsulation of essential oils and volatiles
TL;DR: In this article, a guest inclusion into the apolar CyD cavity is proved by various analytical techniques, including NMR spectroscopy, UV-visible absorption spectrography, optical rotatory dispersion and circular dichroism, fluorescence, infrared/FT-IR spectrographic, thermo-analysis, TLC, mass spectromety, and powder X-ray diffractometry.
Journal ArticleDOI
Advanced Technologies for Oral Controlled Release: Cyclodextrins for Oral Controlled Release
PJ Salústio,Patrícia Pontes,Claudia Conduto,Inês Sanches,Catarina Carvalho,João Arrais,Helena Cabral Marques +6 more
TL;DR: The aim of this work was to review the applications of the CDs and their hydrophilic derivatives on the solubility enhancement of poorly water-soluble drugs in order to increase their dissolution rate and get immediate release, as well as their ability to control the release of drugs from solid dosage forms.
Journal ArticleDOI
A Comparative Study of Naproxen – Beta Cyclodextrin Complexes Prepared by Conventional Methods and Using Supercritical Carbon Dioxide
TL;DR: In this article, the physicochemical properties of the solid complexes prepared by traditional methods (kneading, freeze-drying and spraydrying) and using a supercritical fluid technology were compared.
Journal ArticleDOI
In vitro and in vivo topical delivery studies of tretinoin-loaded ultradeformable vesicles
Andreia Ascenso,Ana Salgado,Carla Euletério,Fabíola Silva Garcia Praça,Maria Vitória Lopes Badra Bentley,Helena Cabral Marques,Helena Oliveira,Conceição Santos,Sandra Simões +8 more
TL;DR: Tretino in-UDV is a promising delivery system for tretinoin dermal delivery without promoting skin irritation (unlike other commercial formulations), which is quite advantageous for therapeutic purpose.
Journal ArticleDOI
The Effect of Lycopene Preexposure on UV-B-Irradiated Human Keratinocytes
Andreia Ascenso,Tiago Pedrosa,Sónia Pinho,Francisco Pinho,José Miguel P. Ferreira de Oliveira,Helena Cabral Marques,Helena Oliveira,Sandra Simões,Conceição Santos +8 more
TL;DR: In this paper, the effects of preexposure to lycopene on UV-B-irradiated skin cells were investigated, and several parameters were analyzed by FCM and RT-PCR: genotoxicity/clastogenicity by assessing the cell cycle distribution; apoptosis by performing the Annexin-V assay and analyzing gene expression of apoptosis biomarkers; and oxidative stress by ROS quantification.
