Surface functionalization of liposomes can play a key role in overcoming the current limitations of nanocarriers to treat solid tumors, i.e., biological barriers and physiological factors. The phospholipid vesicles (liposomes) containing anticancer agents produce fewer side effects than non-liposomal anticancer formulations, and can effectively target the solid tumors. This article reviews info...

background: recent results have provided increasing evidence to support involvement of membrane damage in the mechanism of ionizing radiation induced killing of mammalian cells. these findings have stimulated renewed interest in evaluating the damage to membrane as a primary initiator in radiation-induced cell killing especially in apoptotic death. the present study was aimed to gain deeper ins...

PURPOSE Imatinib inhibits platelet-derived growth factor receptor (PDGFR), and evidence shows that PDGFR participates in the development and progression of cervical cancer. Although imatinib has exhibited preclinical activity against cervical cancer, only minimal clinical therapeutic efficacy was observed. This poor therapeutic efficacy may be due to insufficient drug delivery to the tumor cell...

PURPOSE Enhance skin penetration of hydrophilic and lipophilic compounds using liposomes that are responsible to the pH of the skin surface. METHODS pH-sensitive liposomes were prepared by a thin layer and freeze-thaw method with dioleoyl phosphatidyl ethanolamine and cholesteryl hemisuccinate. Liposomal fusion with stratum corneum lipid liposomes was measured using fluorescence resonance ene...

BACKGROUND Epidermal growth factor receptor (EGFR) is overexpressed in many solid tumor types, such as ovarian carcinoma. Immunoliposome based drug targeting has shown promising results in drug delivery to the tumors. However, the ratio of tumor-to-normal tissue concentrations should be increased to minimize the adverse effects of cytostatic drugs. METHODOLOGY/PRINCIPAL FINDINGS We studied th...

Giant liposomes are proposed as a potential delivery system in marine copepods, the dominant constituent of the zooplankton. Liposomes were prepared in the same size range as the food ingested by copepods (mean diameter of about 7 microm). The encapsulation of a hydrophilic and high molecular mass fluorescent compound, fluorescein isothiocyanate-dextran (FitcDx), within the liposomes provided a...

The major challenge to treat Parkinson’s disease (PD) is penetration of target molecule into the brain to improve the efficacy of drugs. To achieve better brain penetration and targeted delivery, 1,9-Pyrazoloanthrone (1,9-P) loaded liposomes were developed by solvent injection technique using ultrasonication and evaluated for particle size, morphology, entrapment efficiency, FT-IR, and in-vitro...

(DDC)2Zn, disulfiram (DS) metabolite, has shown promisinganticancer effects in vitro but further investigations vivo are limited by itspoor water solubility. In this study, liposomes assessed as a deliverysystem for (DDC)2Zn. Liposomes were prepared the thin-filmhydration method, followed high-pressure homogenisation (HPH) sizereduction. The nano-liposomes then characterised size, polydispersit...

In this work, a lipophilic ophthalmic drug, lutein, has been entrapped in liposomes, using supercritical assisted process. Effects of pressure, temperature, and drug to lipid ratio variation were studied on mean diameters lutein encapsulation efficiency. Liposomes with between 153 ± 38 267 56 nm produced, efficiencies 86.5 0.4% 97.8 1.2% obtained. A Scanning Electron Microscope confirmed spheri...
