Oncolytic viruses (OVs) constitute a promising class of cancer therapeutics which exploit validated genetic pathways known to be deregulated in many cancers. To overcome an immune response and to enhance its potential use to treat primary and metastatic tumors, a method for liposomal encapsulation of adenovirus has been developed. The encapsulation of adenovirus in non-toxic anionic lecithin-ch...

The lymphatic absorption and tissue distribution of free [14C]Adriamycin, "empty" [3H]liposomes, free [14C]Adriamycin plus empty [3H]liposomes, and [14C]Adriamycin entrapped into [3H]liposomes have been examined at intervals after i.p. injection into rats. Following treatment with empty [3H]liposomes, almost 30% of the liposomal lipid marker was recovered in 24-hr thoracic duct lymph, but when ...

Development of technology driven functional and natural health products has a number of challenges since bioactive ingredients incorporated are unstable to processing with reduced absorption, low bioavailability and reduced shelf life. Encapsulation offers a great potential for protecting and delivering bioactive components and micro-organisms through technology driven products to enhance human...

13 The hemagglutinating (HA) activity of Cratylia mollis lectin (Cra) was evaluated and the influence of ultrasound and mechanical agitation on its activity examined. The antitumor activity of Cra-loaded liposomes was also investigated. Liposomes were obtained by the lipid thin film method. Physicochemical characterization was carried out and long-term stability of Cra-loaded liposomes assessed...

Internal wool lipids (IWLs) are rich in cholesterol, free fatty acids, cholesteryl sulfate, and, mainly, ceramides. The repairing effect of these lipids structured as liposomes was demonstrated by reinforcing the skin-barrier integrity and increasing the water-holding capacity when applied onto the skin. This work was focused on the formation of liposomes with IWLs rich in ceramides, obtained a...

Curcumin is a bioactive compound from turmeric which has different biological properties and health benefits such as antioxidant, anti-inflammatory, antimicrobial, and anticancer activities. However, the low solubility, poor bioavailability, and rapid degradation under neutral or alkaline pH conditions or when exposed to light, limit the food applications of curcumin. These problems can be solv...

The purpose of the present study was to formulate effective and controlled release albendazole liposomal formulations. Albendazole, a hydrophobic drug used for the treatment of hydatid cysts, was encapsulated in nanosize liposomes. Rapid evaporation method was used for the preparation of albendazole-encapsulated conventional and PEGylated liposomes consisting of egg phosphatidylcholine (PC) and...

Although the encapsulation of paclitaxel into liposomes has been extensively studied, its significant hydrophobic and uncharged character has generated substantial difficulties concerning its efficient encapsulation into the inner water core of liposomes. We found that a more hydrophilic paclitaxel molecule, 7-glucosyloxyacetylpaclitaxel, retained tubulin polymerization stabilization activity. ...

Using the compound Styrene maleic anhydride (SMA) as a model of a drug, a novel approach for sustained endogenously formed liposome encapsulated drug delivery to the prostate gland has been evolved. Intra vas deferens depot of a combination of high molecular weight SMA (SMAh, the drug) and low molecular weight SMA (SMAl) is formed by one time injection. The SMAh breaks down sperm membrane to pr...
