Parietaria pollen is one of the major causes of allergic reaction in southern Europe, affecting about 30% of all allergic patients in this area. Specific immunotherapy is the only treatment able to modify the natural outcome of the disease by restoring a normal immunity against allergens. The preparation of allergen-solid lipid nanoparticles as delivery vehicles for therapeutic proteins, P. jud...

INTRODUCTION Resveratrol is a polyphenol found in grapes and red wines. Interest in this polyphenol has increased due to its pharmacological cardio- and neuroprotective, chemopreventive, and antiaging effects, among others. Nevertheless, its pharmacokinetic properties are less favorable, since the compound has poor bioavailability, low water solubility, and is chemically unstable. To overcome t...

Lipid nanoparticles can be optimized for the efficient delivery of mRNA via nebulization.

conclusions the results indicated that sod-loaded in sln was delivered into deep burned skin layer and induced high enzyme activity through the skin. low particle size, application of lecithin as surfactant and low crystallinity index (ci) percentage were important factors for increasing sod penetration through the burned rat skin. percentage of activity by sln dispersions through rat skin was ...

Drug delivery research areas is continuously broaden and modified as a results of the realization of many factors (such as poor drug solubility and/or absorption, rapid metabolism, high fluctuation in the drug plasma level and variability) adversely affect in-vivo results, in conventional drug delivery system. Lipids are one of the basic building blocks of biological membranes. Nanoscale-based ...

Purpose: Nanostructured lipid carriers (NLCs) composed of solid lipid and oil are a new generation of lipid nanoparticles which have exhibited some merits over traditional used lipid nanoparticles in fortifying food and beverages and nutraceuticals delivery systems such as liposomes and solid lipid nanoparticles. Methods: In this study, Precirol and Compritol as solid lipids, Miglyol and Octylo...

The aim of this study was to synthesize by high shear homogenization method and to characterize new solid lipid nanoparticles loaded with green tea extract, nanoparticles which show high antioxidant activity. In this respect, cetyl palmitate and glyceryl stearate were used as solid lipids in combination with two nonionic surfactants, Tween20 and Tween80 and an ionic surfactant as lecithin. The ...
