have attracted a lot of interest to develop health and wellness promoting foods and beverages. However, bioactive lipids are water-insoluble and degrade easily during processing and storage, making their addition into foods and beverages challenging. The main objective of this thesis was to develop a novel green process to form bioactive lipid-carrier hollow solid lipid micro-and nanoparticles ...

The present review compiles the applications of lipid nanoparticles mainly solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) for the delivery of pharmaceutical actives. The attempts to overcome the low solubility and bioavailability of some drugs by their incorporation into lipid nanocarriers have been summarized. A special focus of this review is on different routes of ad...

INTRODUCTION Gemcitabine hydrochloride is an antimetabolite (pyrimidine analog) with poor oral bioavailability (9%) due to the first pass metabolism. GEM is a water soluble drug (log p = -1.4) with a short half-life of 42 to 94 minutes (short infusions) and 245 to 638 minutes (long infusions) respectively. Extensive first pass metabolism, low bioavailability, high dosing frequency and less half...

This paper aims to encapsulate into solid lipid nanoparticles a mixture of two bioactive compounds, a photoprotective agent and an antioxidant compound. The co-encapsulation effect of octocrylene sunscreen and flavonoid (luteolinon) has been studied on the specific properties like antioxidant activity, sun protection factor and photostability. Using the high preasure homogenization technique li...

RNA interference technology has been widely applied in biomedical therapy in recent years. A type of small RNA molecule - siRNA could regulate the expression of disease related genes by breaking down the integrity of mRNA with high specificity. However, the low efficiency of siRNA delivery to its target seriously hampered the RNAi therapy. Compared with viral-based delivery systems, non-viral-b...

Topical delivery has the advantages including being user friendly and cost effective. Development of topical delivery carriers for lutein is becoming an important issue for the ocular drug delivery. Quantification of the partition coefficient of drug in the ocular tissue is the first step for the evaluation of delivery efficacy. The objectives of this study were to evaluate the effects of lipid...

Colloidal lipid particles such as solid lipid nanoparticles and liquid crystalline nanoparticles have great opportunities as drug carriers especially for lipophilic drugs intended for intravenous administration. In order to evaluate drug release from these nanoparticles and determine their behavior after administration, emulsion droplets were used as a lipophilic compartment to which the transf...

Developing new functional biomaterials from biocompatible natural-based resources for gene/drug delivery has attracted increasing attention in recent years. In this work, we prepared a series of cationic nanoparticles (Diosarg-DOPE NPs) by assembly of a natural steroid diosgenin-based cationic lipid (Diosarg) with commercially-available helper lipid 1,2-dioleoyl-sn-glycero-3-phosphorethanolamin...
