PURPOSE Agomelatine is a novel antidepressant drug suffering from an extensive first-pass metabolism leading to a diminished absolute bioavailability. The aim of the study is: first to enhance its absolute bioavailability, and second to increase its brain delivery. METHODS To achieve these aims, the nasal route was adopted to exploit first its avoidance of the hepatic first-pass metabolism to...

Chronic wounds and severe burns are diseases responsible for severe morbidity and even death. Wound repair is a crucial process and tissue regeneration enhancement and infection prevention are key factors to minimize pain, discomfort, and scar formation. The aim of this work was the development of lipid nanoparticles (solid lipid nanoparticles and nanostructured lipid carriers [NLC]), to be loa...

Alopecia is a dermatological disorder, commonly known as hair loss, which affects up to half of the Caucasian male population by middle age, and almost all (95%) Caucasian men by old age. Considering that alopecia affects so many people and that there is currently no scientifically proven treatment with few side effects, new drug-delivery systems able to improve alopecia therapy are urgently re...

Objective: Oxidative stress is a leading factor in the development of silver nanoparticle-induced toxicity. This study evaluated the effects of oral prescription of different doses of silver nanoparticles and propolis on lipid peroxidation in male Wistar rats. Materials and Methods: The male wistar rats were randomly divided into four groups. Control group and three different treatment groups ...

The present study was aimed at developing aqueous dispersion of Ketorolac-loaded solid lipid nanoparticles (SLN) by high speed stirring followed by ultrasonication technique and then incorporation into freshly prepared gel for transdermal delivery. A statistical central composite design was applied to study the effect of drug/lipid ratio and soya lecithin concentration on particle size and entr...

The candesartan cilexetil belongs to class II of the biopharmaceutical classification system and bioavailability is 15% due to the poor aqueous solubility. The purpose of the study is to improve aqueous solubility by nano technology of solid lipid nanoparticle by solvent evaporation method. Here glyceryl monosterate (lipid), polaxemor 407, tweeen 80 (co-surfactant and surfactant respectively) a...

AIM To analyze the neurotoxic potential of synthesized magnetite nanoparticles coated by dextran, hydroxyethyl starch, oxidized hydroxyethyl starch, and chitosan, and magnetic nanoparticles combined with ferritin as a native protein. METHODS The size of nanoparticles was analyzed using photon correlation spectroscopy, their effects on the conductance of planar lipid membrane by planar lipid b...

Ionizable Lipid Nanoparticles nanoparticle (LNP) systems are currently the leading nonviral delivery for enabling clinical potential of mRNA drugs. lipid is critical component nanoparticles. In article 2202590 by Gengshen Song, Jing Yang, Shengqi Wang, and co-workers, a novel ionizable YK009 designed developed LNP formulation. The YK009-LNP shows high efficacy good safety. An vaccine against SA...

Lipid-coated metal nanoparticles are developed here as a mimic of low-density lipoprotein (LDL) particles and used to study C-reactive protein (CRP) binding to highly curved lipid membranes. A 12 nm shift in the localized surface plasmon resonance (LSPR) was observed when CRP was added to the lipid-coated gold nanoparticles. Transmission electron microscopy (TEM) revealed that CRP induced a str...
