The aim of the present study was to investigate the potential of nanoemulsion formulations for transdermal delivery of celecoxib (CXB). The in vitro skin permeation profile of optimized formulations was compared with CXB gel and nanoemulsion gel. Significant increase in the steady state flux (Jss), permeability coefficient (Kp) and enhancement ratio (Er) was observed in nanoemulsion formulation...
A dual-frequency ultrasound transducer (DFUT) is usually preferred for its numerous advantageous applications, especially in biomedical imaging and sensing. However, most of DFUTs are based on the combination of fundamental and harmonic operations, or integration of multiple different single-frequency ultrasound transducers, hindering perfect beam alignment and acoustic impedance matching. A no...
Ultrasound has been widely utilized for medical diagnosis and therapy due to its ability to penetrate deep-seated tissue with less attenuation of energy and minimal undesirable side-effects. Functionalized fullerenes, such as polyhydroxy fullerene (PHF), have attracted particular attention due to their water solubility and potential application in tumor imaging and therapy as carbon nanomateria...
aim : to create an orthotopic hepatoma model with local metastasis monitored with ultrasound could be created as a platform for testing new treatments. background : hepatoma accounts for 25% of liver tumors in children with poor overall survival. intraabdominal metastasis are present in 35% of patients at time of diagnosis. we hypothesized that an orthotopic tumor model with local metastasis...
Nanoemulsions are particularly suitable as a platform in the development of delivery systems. The type of nanoemulsion with a higher stability will offer an advantage in the preparation of a delivery system for lipophilic drugs. Nanoemulsions can be fabricated by different processing methods, which are usually categorized as either high- or low-energy methods. In this study, a comparison betwee...
BACKGROUND The stability of protein drugs remains one of the key hurdles to their success in the market. The aim of the present study was to design a novel nanoemulsion drug-delivery system (NEDDS) that would encapsulate a standard-model protein drug--bovine serum albumin (BSA)--to improve drug stability. METHODS The BSA NEDDS was prepared using a phase-inversion method and pseudoternary phas...
