The aim of the present study was to evaluate the stability of celecoxib (CXB) using novel nanoemulsion formulation. Optimized nanoemulsion formulation of CXB was prepared by low energy emulsification method. Stability studies were performed for the period of 3 months. Droplet size, viscosity and refractive index (RI) were determined during storage. Shelf life of nanoemulsion formulation was als...

The aim of this work is to develop a curcumin nanoemulsion for transdermal delivery. The incorporation of curcumin inside a nanoglobul should improve curcumin stability and permeability. A nanoemulsion was prepared by the self-nanoemulsification method, using an oil phase of glyceryl monooleate, Cremophor RH40 and polyethylene glycol 400. Evaluation of the nanoemulsion included analysis of part...

The objective of the present investigation was to evaluate potential of nanoemulsions as a coating material for the tablets. The nanoemulsion of size less than 100 nm was prepared using a simple and low-energy spontaneous emulsification method. Conventional tablets containing theophylline as a model hydrophilic drug were prepared. The theophylline tablets were coated with the nanoemulsion using...

results the frequency of bi-rads category 3 lesions detected on screening ultrasound was 18% (90/500). of these patients, one was eventually proven to have malignancy with malignancy rate of 1.1%. this detected malignancy was early breast cancer with no lymph node metastasis. conclusions although the frequency of ultrasound bi-rads category 3 lesions is considerably high (18 %), the malignancy ...

Recent toxicology studies suggest that nanosized aggregates of fullerene molecules can enter cells and alter their functions, and also cross the blood-brain barrier. However, the mechanisms by which fullerenes penetrate and disrupt cell membranes are still poorly understood. Here we use computer simulations to explore the translocation of fullerene clusters through a model lipid membrane and th...

The aim of the present study is to formulate and investigate the potential of nanoemulsion formulation for topical delivery of ketoprofen. In this study, Palm Oil Esters (POEs) a newly introduced oil by Universiti Putra Malaysia researchers was chosen for the oil phase of the nanoemulsion, because the oil was reported to be a good vehicle for pharmaceutical use. Oil-in-water nanoemulsion was pr...

Nanoemulsions are a class of emulsions with a droplet size in the range of 50–500 nm and have attracted a great deal of attention in recent years because it is unique characteristics. The physicochemical properties of nanoemulsion suggests that it can be successfully used to recover the residual oil which is trapped in the fine pore of reservoir rock by capillary forces after primary and second...

ABSTRACT Objective(s): The oil-in-water (O/W) nanoemulsion is expanded in biomedical application due to their special properties. Mint and Parsley are known herbs with many health benefits. Chitosan (Ch) is a low toxic, biodegradable, biocompatible and safe polymer with the antibacterial activity which is used in production of nanomaterial. The aim of this study was to evaluate the nanoem...

The objectives of this study were to explore the inhibition mechanism of lung cancer cells A549 and H460 by curcuminoid extracts and nanoemulsions prepared from Curcuma longa Linnaeus. In addition, human bronchus epithelial cell line BEAS-2B (normal cell) was selected for comparison. A high-performance liquid chromatography (HPLC) method was developed to separate and quantify the various curcum...

A one-step, economical nanoemulsion method has been introduced to synthesize low-melting-point metallic nanoparticles. This nanoemulsion technique exploits the extremely high shear rates generated by the ultrasonic agitation and the relatively large viscosity of the continuous phase - polyalphaolefin (PAO), to rupture the molten metal down to diameter below 100 nm. Field's metal nanoparticles a...
