Proniosome formulations for pulmonary drug delivery
… Omron Micro Air NEU22 (passively vibrating-mesh) nebulisers. The Pari and Aeroneb Pro nebulisers generated higher aerosol and drug outputs compared with the Omron nebuliser. Whilst drug output was around 80% for the Pari and the Aeroneb Pro, it was around 70% for the Omron. Similarly, droplet size …

ANTIMONY SPECIATION BY CHROMATOGRAPHIC SAMPLE INTRODUCTION TO PLASMA SPECTROSCOPY
… first time. A fundamental investigation of the nebuliser/spray chamber assembly was carried out in terms of the effect on the quality of the chromatographic separations. It was found that the resolution was strongly dependent upon choice of nebuliser and spraychamber. Five nebulisers and two …

Development of a Dry Powder Inhaler and Nebulised Nanoparticle-Based Formulations of Curcuminoids for the Potential Treatment of Lung Cancer. Development of Drug Delivery Formulations of Curcuminoids to the Lungs using Air Jet Milling and Sonocrystallisation Techniques for Dry Powder Inhaler Preparations; and Nanoemulsion and Microsuspension for Nebuliser Formulations
Curcuminoids have strong anticancer activities but have low bioavailability. The highest rate of cancer deaths comes from lung tumours; therefore, inhaled curcuminoids could treat lung cancer locally. To date, there are no nebulised formulations of curcuminoids, and there are no inhalable …

Elemental speciation and miniaturised sample introduction studies for inductively coupled plasma mass spectrometry
… spray chambers. A low flow micro-concentric nebuliser (MicroMist) is used to generate the sample aerosol. No sample recondensation is ever observed in the evaporation chamber at flow rates up to 20 micro-l/min. A comparison with a commercial low volume cyclonic spray chamber (Cinnabar) is …

Relative bioavailability of terbutaline to the lungs following inhalation using different methods.
… Aeroneb Pro (vibrating mesh) and Sidestream jet nebulisers were determined by the CEN methodology and the Next Generation Impactor (NGI) methodology. The Aeroneb Pro was found to have significantly better aerodynamic properties than the Sidestream. The results from the NGI method were …

Proliposome Technology for Protein Delivery
… for respiratory tract delivery via medical nebulisers and nasal sprays with different operating principles. Liposomes generated from the proliposome technology were multilamellar as cryo-TEM studies revealed. The generated liposomes were capable of entrapping considerable concentrations of …

INVESTIGATION OF CHEMOMETRICS METHODS FOR CHARACTERISING DRIFT PHENOMENA IN iCK-AES
… (i.e. robust conditions, high RF power and low nebuliserflow rate). At soft conditions, low RF power and medium to high nebuliser flow rate, the system Is very unstable and intemal standardisation is not fully effective as a correction method. For such conditions, a novel correction procedure …

THE INTERFERENCE FREE DETERMINATION OF SELENIUM IN ENVIRONMENTAL AND CLINICAL SAMPLES BY ICP-MS
… of both nitrogen and helium to the argon nebuliser and outer gas streams, resulted in a reduction in the interference from argon polyatomic species. Careful optimisation of plasma parameters such as RF power and gas flow rates using a plasma containing 50% helium in the argon outer gas …

Proliposome and Prosurfactosome Formulations for Pulmonary Drug Delivery
… was studied using PARI LC sprint air jet nebuliser, Aeroneb pro and Beurer iH50 vibrating mesh nebulisers. Two stage (Twin) impinger was used to study the potential suitability of the generated vesicles for inhalation. VMD, span and zeta potential of vesicles before and after nebulisation …

FLUORESCENCE STUDIES IN THE INDUCTIVELY COUPLED PLASMA
… i.e. forward power; viewing height ALC; plasma, nebuliser and auxiliary gas flow rates. Once the optimum conditions had been determined, calibration curves were plotted for each of the elements studied (Ba, Li, Mg and Na). The calibration showed excellent linearity over five orders of magnitude …

Development of dry powder Inhaler and nebulised nanoparticles formulations of chrysin for the potential treatment of asthma. Development of dry powder inhaler of chrysin and nebulised nanoemulsion combination of chrysin and budesonide; Evaluating the anti-inflammatory activity of the combination formulation of chrysin and budesonide for asthma
Chrysin is a flavonoid that can be used as a medication for asthma and chronic obstructive pulmonary disease due to its anti-inflammatory activities. However, no studies have investigated the effectiveness of an inhaled formulation of chrysin on its own or in combination with corticosteroids. …
