Lipid nanoparticles for the topical delivery of retinoids and derivatives
(Future Medicine Ltd., 2015)
Retinoids are lipophilic compounds that are highly used in cosmetics/therapeutics for skin disorders. Conventional formulations are limited by poor water solubility, high chemical/photochemical instability and the irritation ...
Lipid oxidation in biscuits: comparison of different lipid extraction methods
This study was conducted in order to describe a proper method of extraction and quantification of peroxides in a complex matrix as biscuits. Different lipid extraction methods were applied in low lipid biscuits: direct ...
Lipid peroxidation modifies the assembly of biological membranes "The lipid Whisker Model"
(Frontiers Media, 2015-01)
The aim of this opinion article is to point out the basic principles that modify the assembly of biological membranes during lipid peroxidation. With this objective in mind I describe: the structural and functional ...
Nuclear lipid droplets: a novel nuclear domain
(Elsevier Science, 2013-02)
We investigated nuclear neutral-lipid (NL) composition and organization, as NL may represent an alternative source for providing fatty acids and cholesterol (C) to membranes, signaling paths, and transcription factors in ...
Lipid-packing perturbation of model membranes by pH-responsive antimicrobial peptides
The indiscriminate use of conventional antibiotics is leading to an increase in the number of resistant bacterial strains, motivating the search for new compounds to overcome this challenging problem. Antimicrobial peptides, ...
Lipid peroxidation modifies the picture of membranes from the “Fluid Mosaic Model” to the “Lipid Whisker Model”
(Elsevier Masson, 2012-01)
The “Fluid Mosaic Model”, described by Singer and Nicolson, explain both how a cell membrane preserves a critical barrier function while it concomitantly facilitates rapid lateral diffusion of proteins and lipids within ...
Tocopherol in the lipid stability of tilapia (Oreochromis niloticus) hamburgers
Presence of tocopherol is effective for fish preservation during frozen storage, inhibiting lipid degradation by oxidation. This work evaluated the antioxidant effects of α-tocopherol in diet and postmortem addition on the ...
Inclusion of the Helper Lipid Dioleoyl-Phosphatidylethanolamine in Solid Lipid Nanoparticles Inhibits Their Transfection Efficiency
(Amer Scientific PublishersValenciaEUA, 2014)
Changes in lipid composition in hippocampus early and late after status epilepticus induced by kainic acid in wistar rats
Oxidative damage to biological membranes has been reported as a cause of alterations in many different diseases. We had previously reported lipid peroxidation in the kainic acid model of temporal epilepsy. In this study ...
Kinetic of phospholipid oxidation in liposomal suspensions
(eSAT Publishing House Pvt. Ltd, 2014-11)
In this paper, the effects of temperature, the addition of a free radical generator and the lipid content on the oxidation rate of phospholipids were investigated. Soy lecithin liposomes obtained by reverse-phase evaporation ...
