Pulmonary drug delivery can have several advantages over other administration routes, in particular when using dry powder formulations. Such inhalation formulations generally include natural and bio-inspired excipients, which, among purposes, are used to improve dosing reproducibility aerosolization performance. Amino acids enhance dispersibility provide protection against moisture uptake. Suga...

BACKGROUND AND AIM: Different studies evaluating one-step self-etch (SE) adhesive systems show contradictory findings, so the aim of this study was to compare the microleakage of one-step SE adhesive systems and CLEARFIL SE BOND (that serves as the “gold-standard” SE adhesive) with low shrinkage composites. METHODS: In this in vitro study, Class V cavities with the occlusal margin in enamel and...

In this paper dynamic damping properties of a nominated flexible structural adhesive have been identified using an extended-direct modal based joint identification method. It has been revealed that damping characteristics of adhesive are correlated to both frequency and mode shape. Young’s and shear moduli increase with frequency but damping on the other hand, decrease. The results showed that ...

in this study, the usage of starch as adhesives in packaging industry and improving the properties of starch on the development of its applications have been discussed. starch is widely used in various industries, but in the celluloses packaging industry it can be just used as a coating binder, sizing agent or adhesive industries. in these industries, high print quality, low water absorption an...

background: the clinical success of sandwich technique depends on the strength of resin-modified glass ionomer cement (rmgic) bonding to both dentin and resin composite. therefore, the shear bond strength (sbs) of resin composite bonded to rmgic utilizing different resin adhesives versus a gic-based adhesive was compared. materials and methods: in this in vitro study, 84 holes (5×2 mm) were pre...

Hydrophobic grade fumed silicas are generally used in tabletting as lubricants. They are also found to retard the release of pharmaceutical actives. This is because of their hydrophobic nature, which gives good cohesive and adhesive properties. considering this point it was thought that they could be used as dry coating agents for solid dosages forms. The model drug selected for this work was p...
