Background: Solid lipid nanoparticles (SLN) have drawn increasing interest in recent years. These are formed from stable or solid mixtures and then stabilized by emulsifiers. As nanoparticles, colloidal particles running size somewhere the 10 to 1000 nm range known. SLN provides fascinating properties, such as minimal scale, massive surface area, high medication piling, correspondence of stages...

objectives colloidal drug delivery system, solid lipid nanoparticles (slns), helps to increase the solubility of the drug and its oral bioavailability. methods tamoxifen (tam) as a nonsteroidalantiestrogen drug was formulated in sln and an in vitro study was conducted to determine the cytotoxicity effect of tam-loaded slns on human breast cancer cell lines mcf-7 (estrogen receptor-positive) and...

The purpose of this study was to use solid lipid nanoparticles (SLN) to improve the pharmacological activity of ofloxacin. Ofloxacin-loaded SLN were prepared using palmitic acid as lipid matrix and poly vinyl alcohol (PVA) as emulsifier by a hot homogenization and ultrasonication method. The physicochemical characteristics of SLN were investigated by optical microscope, scanning electron micros...

Solid lipid nanoparticles (SLNs) of coenzyme Q10 (CoQ10) were formulated by a high-pressure homogenization method. The best formulation of SLN dispersion consisted of 13% lipid (cetyl palmitate or stearic acid), 8% surfactant (Tween 80 or Tego Care 450), and water. Stability tests, particle size analysis, differential scanning calorimetry, transmission electron microscopy, and release study wer...

Solid lipid nanoparticles (SLN) have been reported to be an alternative system to emulsions, liposomes, microparticles and their polymeric counterparts for various application routes since the early 1990s due to their advantages. Various research groups have also increasingly focused on improving their stability in body fluids after administration by coating of particles with hydrophilic molecu...

The objective of the current study was to formulate solid lipid nanoparticles of oxybenzone to enhance its sunscreening efficacy while reducing its side effects. Solid lipid nanoparticles (SLNs) of oxybenzone were prepared by the solvent diffusion method. A complete 2(4) factorial design was used to optimize preparations. The study design involves the investigation of four independent variables...

Sarcolipin (SLN), a 31 amino acid integral membrane protein, regulates SERCA1a and SERCA2a, two isoforms of the sarco(endo)plasmic Ca-ATPase, by lowering their apparent Ca(2+) affinity and thereby enabling muscle relaxation. SLN is expressed in both fast-twitch and slow-twitch muscle fibers with significant expression levels also found in the cardiac muscle. SLN shares approximately 30% identit...

The aim of this study was to evaluate in vitro the permeation of the antioxidant agent Idebenone (IDE) loaded into solid lipid nanoparticles (SLN) across MDCKII-MDR1 cell monolayer, selected as an in vitro model of the Blood Brain Barrier (BBB). SLN were prepared using cetyl palmitate as solid lipid and different non-ionic surfactants, oleth-20, ceteth-20 and isoceth-20, by the phase inversion ...

BACKGROUND One of the major obstacles in the treatment of breast cancer is breast cancer stem cells (BCSC) which are resistant to standard chemotherapeutic drugs. It has been proven that microRNA-200c (miR-200c) can restore sensitivity to microtubule-targeting chemotherapeutic drugs by reducing the expression of class III β-tubulin. In this study, combination therapy with miR-200c and paclitaxe...
