Liposomes are widely used as drug delivery systems in different forms including osmotic pumps, infusion and IV injection. In spite of these, there is no data available about their behavior under convective flow (e.g. infusion or osmotic pumps) and upon stagnation in such drug delivery systems. As a part of a series of investigations in this area, the present study investigates the effects of vi...

Abstract: Aim: Berberine hydrochloride is a Traditional Chinese Medicine component with antibacterial, antiviral, anti-inflammatory, antioxidant and lowering blood sugar effects. However, the application of berberine has been hindered for long time due to its poor solubility low bioavailability. This study aims design liposomes-gel enhance bioavailability activity hydrochloride. Materials Metho...

objective(s) the objective of this study was to prepare, characterize and evaluate the nanoliposomes containing safranal as a natural sunscreen and moisturizer factor. materials and methods the experimental formulations included homosalate reference, nanoliposomes containing 0.25, 0.5, 1, 2, 4 and 8% safranal and empty liposomes. the liposomes were prepared using fusion method and homogenizatio...

Liposomes, as biocompatible and safe nanocarriers with easily modified surfaces, can be well used in the field of antitumor. Their targeting properties have contributed to reduction drug dosage non-target cell toxicity. To further exploit liposomes, passive active liposomes physicochemical been constructed by surface modification. This paper summarizes mechanisms action different types targeted...

Liposomes are sphere-shaped vesicles made up of one or more bilayers phospholipids. The ability delayed to transport medications, vaccines, diagnostic specialists, and other bioactive operators has accelerated development in the liposomal drug delivery system. system's pharmacyelements pharmacokinetics properties have been altered, resulting a higher therapeutic index lower overall toxicity. Th...

The purpose of this study was to optimize a method for the encapsulation of P5 peptide, a new designed peptide containing MHC class I epitopes from rat HER2/neu protein, into liposomes as an approach for breast cancer vaccine formulation. The efficiency of liposomal encapsulation of peptides is generally low and development of an optimized method to increase encapsulation efficiency is a big ch...

Background and aim: Efficacy of vaccines is mainly depending on the type of adjuvant used. Efficacy trials of first generation vaccine against leishmaniasis showed a limited efficacy due to lack of an appropriate adjuvant. The objective of this study was to investigate whether positively charged liposomes containing ALM could induce Th1 type immune response in susceptible Balb/c mice.Mate...

The aim of current study was to investigate the effect of Brij decoration of liposomes on in vitro and in vivo characteristics of the nanocarriers. Two hydrophilic Brij surfactants (Brij 35 and Brij 78) with almost similar molecular weight but differing in acyl chain were incorporated into liposomal bilayers at two percentages (5% and 10%). Conventional liposomes (CL) containing egg phosphatidy...

introduction : the encapsulation of nutraceuticals in lipid based carriers, such as liposomes, can lead to increasing of bio-active ingredients bioavailability and controlled release, maintaining their stability in different environmental conditions and increasing solubility of hydrophobic active ingredients in aqueous conditions. food grade liposomes are being increasingly used in food industr...

Assembling structures to divide space controllably and spontaneously into subunits at the nanometer scale is a significant challenge, although one that biology has solved in two distinct ways: prokaryotes and eukaryotes. Prokaryotes have a single compartment delimited by one or more lipid-protein membranes. Eukaryotes have nested-membrane structures that provide internal compartments--such as t...
