It is, sometimes, desirable to maintain a constant plasma drug concentration within the therapeutically effective concentration range. The use of high viscosity hydromiscible vehicles such as hydrophilic gels, is one of various approaches for controlled drug delivery, and represents an important area of pharmaceutical research and development. Of these systems, Pluronic F-127 (PF-127) provides ...

Pluronic based nano-particulate systems are innovative platforms for delivery of anti-cancer agents. These systems due to their pharmacological properties and suitable physicochemical characteristics are great opportunity for development cancer therapeutics. This mini-review tries to provide a more detailed overview on the currently available pluronic based drug delivery systems. In the section...

Calcium phosphates like hydroxyapatite (HA), beta-tricalcium phosphate (beta-TCP), and their mixtures (biphasic calcium phosphates; BCP) are used clinically to repair bone defects. These materials can be difficult to handle and have no inherent biological activity. Handling properties of other bone substitute materials have been improved by combining them with an inert carrier such as Pluronic ...

Herein, we explore the potential use of two micelle-forming block copolymers, i.e., Pluronic F-127 and poly(ethylene oxide)-b-poly(caprolactone), for application of fungicide agents. The polymer effect on the in vitro fungicide activity of a series of geranyl orcinol derivatives against Botrytis cinerea has been assessed. The results show that, for all test compounds, the incorporation into mic...

Because mononuclear phagocytes take up perfluorochemical emulsions (PFCE), we examined how prior treatment with PFCE affects the fate of circulating bacteria. Rats were preinjected with three daily intravenous injections of PFCE (2.0 ml/100 g) containing 12.5% (vol/vol) of a 4:1 mixture of F-dimethyl adamantane and F-trimethylbicyclo-nonane, 2.5% (wt/vol) Pluronic F-68 as the emulsifying agent,...

Aggregation of thermosensitive polymer-coated gold nanoparticles was performed in aqueous solution in the presence of a triblock copolymer poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (Pluronic P123, PEO(20)-PPO(68)-PEO(20)). The gold nanoparticles, AuNPs, which are covered by thermosensitive statistical copolymers poly(EO(x)-st-PO(y)), aggregate when the temperat...

Pluronic F-127 (PF-127) hydrogel is a versatile biomaterial with promising applications in drug delivery, tissue engineering, and regenerative medicine. PF-127 has antiadhesive activity that prevents bacterial adhesion by creating hydrated layer on the surface. This property makes suitable for preventing implant-associated infections. In this study, we aimed to evaluate antibacterial properties...

This research was designed to provide the first protocol establish an efficient solution for direct organogenesis regeneration in Passiflora quadrangularis using nodal explants from young shoots. Passifloraceae tissue culture has been associated with problems such as recalcitrance, sensitivity ethylene accumulation and browning of due presence phenols tissues. Due high rate endogenous contamina...

Domperidone is practically insoluble prokinetic drug; the systemic bioavailability of the drug following oral administration is only 13-17% because of extensive presystemic metabolism in the gut wall and liver. The applicability of the solid dispersion technique as a method for enhancing absorption of the drug through achieving better dissolution characteristics and better bioavailability for d...

Electromigration capillary methods are promising techniques in proteomics and they are still under research. We used a partial filling approach, i.e. a combination of gel and non-gel separation mechanisms in a single dimension. We tried using an interesting gel, Pluronic F 127, which can be considered as a surfactant capable of self-association both with isotropic and anisotropic gels. The Plur...
