In the present study solid dispersions of the antifungal drug Ketoconazole were prepared with Pluronic F-127 and PVP K-30 with an intention to improve its dissolution properties. Investigations of the properties of the dispersions were performed using release studies, Differential scanning calorimetery (DSC), X-ray powder diffraction (XRD) and Fourier transform infrared (FTIR). The results obta...

The aim of the present study was to formulate and evaluate nystatin containing thermosensitive mucoadhesive gel for vaginal drug delivery to achieve prolonging the residence time, sustained drug release, enhancing efficacy, decreasing recurrence, and increasing patient compliance in the treatment for vaginal candidiasis. Here nystatin (1%) as a model drug. A 3 full factorial design was employed...

BACKGROUND Surfactants may reduce the adhesion force holding bubbles to the vessel wall in gas embolism. The authors measured bubble adhesion force using excised microvessels. They assessed endothelial damage by measuring vessel reactivity and with microscopy. METHODS Microbubbles injected into arterioles resided for 5, 10, or 30 min, with intact or damaged endothelium. Perfusion was with rat...

Poloxamer micelles promise safety and efficacy for many water insoluble drugs. Chrysin has been reported to have anticancer, anti-inflammatory, antioxidant, and anti-aromatase activities but its water insoluble properties limit its pharmaceutical application. In the present study, chrysin loaded poloxamer micelles were developed. Two types of poloxamers, Pluronic F-68 and Pluronic F-127 were co...

The purpose of this study was to develop Pluronic F127 (PF127) based formulations of timolol maleate (TM) aimed at enhancing its ocular bioavailability. The effect of isotonicity agents and PF127 concentrations on the rheological properties of the prepared formulations was examined. In an attempt to reduce the concentration of PF127 without compromising the in situ gelling capabilities, various...

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 work reports on the new chemical dosimeters for UV radiation dose measurements coral reefs and in seawater. The proposed can measure actual of radiation, which consists 95% UVA 5% UVB unlike currently-used radiometers marine ocean waters that separately. are composed water, poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (Pluronic F-127) as a gel matrix, 2,3,5-t...

Additive manufacturing of porous Ti6Al4V (Ti64) parts is promising for biomedical applications. In this study, Ti64 scaffolds with two scales interconnected porosity networks were developed using a direct-ink writing process. Inks made by dissolving copolymer (Pluronic F-127) in water to obtain hydrogel, which was then loaded particles. Both Pluronic F-127 amount the hydrogel and solid loading ...

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...
