Multiple phase emulsions are increasingly used as alternatives to simple emulsions in personal care products. One of the major advantages of these emulsions over simple emulsions is slow and controlled release of their ingredients. Other favorite cosmetic characteristics of multiple emulsions include occlusivity (in O/W/O emulsions), esthetics and consumer(More)
In the last decade, almost one-third of the newly discovered drugs approved by the US FDA were biomolecules and biologics. Effective delivery of therapeutic biomolecules to their target is a challenging issue. Innovations in drug delivery systems have improved the efficiency of many of new biopharmaceuticals. Designing of novel transdermal delivery systems(More)
This study describes the formulation and characterization of O/W and W/O creams containing urea-loaded microparticles prepared with poly (D, L-lactic-co-glycolic acid) (PLGA) in order to encapsulate and stabilize urea. The solvent evaporation method was used for preparing PLGA microparticles containing urea. The microparticles size was evaluated by laser(More)
This work describes the formulation and characterization of urea-loaded microspheres prepared using various polymers such as ethyl cellulose (EC), cellulose acetate phthalate (CAP) and poly (D,L-lactic-co-glycolic acid) (PLGA), along with the utilization of a solvent evaporation technique. The effect of various formulation parameters (i.e. polymer type and(More)
BACKGROUND Transmembrane delivery of active peptides and proteins, including skin delivery of cosmeceutical proteins such as collagen and elastin, has been a challenging issue. Amphipathic cell-penetrating peptides (CPPs) have been proposed as carrier peptides to mediate cellular uptake of proteins without covalent binding. MATERIALS AND METHODS In this(More)
In this study, gelatin microspheres containing lactic acid were prepared by the polymerization technique using glutaraldehyde as the cross-linking agent. Dried microspheres were loaded by immersing them in an aqueous solution of lactic acid. In order to prepare microspheres with an appropriate drug release profile, the effect of time of cross-linking and(More)
Gelatin microspheres containing lactic acid were prepared by a polymerization technique using glutaraldehyde as the cross-linking agent. Because particle size distribution of microspheres is a vital factor in the characterization of microspheres, the present study was carried out to evaluate the effect of process variables on the microspheres size(More)
Wound healing is a dynamic and complex biological process, which requires coordinated events including haemostasis, inflammation, proliferation, revascularisation and remodelling. Impaired wound healing is a common problem that occurs in both community and hospital settings. Various experimental and clinical studies have evaluated different modalities for(More)
Pressure ulcer (PrU)-related hospitalisation and mortality are critical issues in medical and surgical patients. Although animal studies have suggested the beneficial effects of sildenafil on wound healing, related clinical data are lacking. This is the first clinical study that has evaluated the effects of topical sildenafil on PrU healing in human(More)
