A novel composite liposomal system co-encapsulating paclitaxel (PTX) with chloroquine phosphate (CQ) was designed for treating PTX-resistant carcinoma. It was confirmed that liposomal CQ can sensitize PTX by means of autophagy inhibition and competitively binding with multidrug-resistance transporters. Furthermore, according to the in vitro cytotoxicity and apoptosis assay, real-time observatio...

UNLABELLED Solar radiation causes damage to human skin, and photoprotection is the main way to prevent these harmful effects. The development of sunscreen formulations containing nanosystems is of great interest in the pharmaceutical and cosmetic industries because of the many potential benefits. This study aimed to develop and evaluate an octyl methoxycinnamate (OMC) liposomal nanosystem (lipo...

The possibility of using glycol chitosan to obtain stabilized liposome containers for doxorubicin delivery is demonstrated. The dissociation constants of the liposome complexes with glycol chitosan (3.4 × 10–4 and 1.10 × 10–5 depending on the aggregation state of the liposomes) are determined. It is shown that the formation of liposome complexes with glycol chitosan has a significant prolongati...

Recent studies have demonstrated the presence of unesterified cholesterol-rich, liposome-like vesicles in the extracellular space of atherosclerotic lesions in humans and animals. Liposome-like vesicles accumulate in the subendothelial space in rabbits within 2 weeks of initiation of cholesterol feeding, well before foam cells appear. These observations suggest that extracellular liposome-like ...

BACKGROUND Liposome bupivacaine is a novel formulation of the local anesthetic bupivacaine, designed to provide prolonged postsurgical analgesia. This analysis examined pooled efficacy data as reflected in cumulative pain scores from 10 randomized, double-blind liposome bupivacaine clinical studies in which the study drug was administered via local wound infiltration. METHODS A total of 823 p...

CONTEXT Liposomes have been shown to improve human red blood cell (RBC) in vitro quality by minimizing membrane damage occurring during 42-d hypothermic storage. Small animal models are necessary to evaluate novel blood products and guide future clinical studies. OBJECTIVES The aim of this study was to assess the effect of liposome treatments on rat RBC hypothermic storage lesion (HSL) and to...

BACKGROUND Transcutaneous vaccines have received wide attention due to their easy-to-use, needle-free, noninvasive delivery. However, the novel barrier function of stratum corneum hinders the transport of antigen and adjuvant in transcutaneous immunization. Novel nanoscale delivery systems employing, for example, liposomes and nanoparticles, have been widely investigated to overcome the penetra...

Title: CONTROLLED LIPOSOME FORMATION AND SOLUTE ENCAPSULATION WITH CONTINUOUS-FLOW MICROFLUIDIC HYDRODYNAMIC FOCUSING Andreas Jahn, Doctor of Philosophy, 2008 Directed By: Professor Don L. DeVoe, Department of Mechanical Engineering Liposomes enable the compartmentalization of compounds making them interesting as drug delivery systems. A drug delivery system (DDS) is a transport vehicle for a d...

objective(s)cpg oligodeoxynucleotides (cpg odns) have been shown to have potent immunostimulatory adjuvant activity for a wide range of antigens. due to susceptibility of phosphodiester cpg odns (po cpg) to nuclease degradation, nuclease-resistant phosphorothioate cpg odns (ps cpg) were currently utilized in an in vivo model. in this study, according to some recently reported drawbacks with ps ...

background : historically, leishmanization is the most effective protective measure against cutaneous leishmaniasis (cl), cl lesion induced by leishmanization sometimes takes a long time to heal. ma­nipulation of leishmanization inoculums needed to induce a mild and acceptable cl lesion. the aim of this study was to explore if liposomal form of cpg odn (cytosin phosphate guanin oligodeoxynu­cle...
