Abstract A novel fire-retardant epoxy thermoset, containing boron polyol complex, was prepared and characterised. The additive a stoichiometric mixture of boric acid glycerol. Flame retardancy the resin improved by formation stable char layer that protected underlying from further burning. Phonon transport through polymer matrix via hydrogen bonding identified. acted as thermal bridge for inter...

A resin-bound dinuclear zinc(II) complex for the selective capture of pyrophosphopeptides is reported. The metal complex binds diphosphate esters over other anionic groups, such as monophosphate esters, sulfate esters, and carboxylic acids, with high specificity. Immobilization of the compound provided a reagent capable of binding and retaining nanomolar quantities of pyrophosphopeptide in the ...

The options for the fibre reinforcement of polymer matrix composites cover a range from short-fibre chopped strand mat, through woven fabric to unidirectional pre-impregnated (prepreg) reinforcements. The modelling of such materials may be simplified by assumptions such as perfect regular packing of fibres and the total absence of fibre waviness. However, these and other features such as the cr...

Natural resources in general and plant materials in particular are receiving more attention due to their safety as pharmaceutical excipients. Present work assessed the combination potential of natural hydrophobic resin, rosin, and synthetic polymer ethyl cellulose to mask the abhorrent inherent taste of ambroxol hydrochloride, by microencapsulation technique, and its possibility to formulate as...

Aim and Background:Taxol is a known substrate for P-glycoprotein, which induces drug resistance to cancerous cells. Therefore radiolabeled taxol can be a suitable probe for imaging of the P-glycoprotein transport ability to determine drug resistance. The aim of this study was to provide labeled taxol and to determine the rate of uptake in the tumor to evaluate the location of the tumor and the ...

In addition to sculpting eukaryotic transcripts by removing introns, pre-mRNA splicing greatly impacts protein composition of the emerging mRNP. The exon junction complex (EJC), deposited upstream of exon-exon junctions after splicing, is a major constituent of spliced mRNPs. Here, we report comprehensive analysis of the endogenous human EJC protein and RNA interactomes. We confirm that the maj...

A dentin-cement-prosthesis complex restored with either all-porcelain, cured resin-composite, or cast base metal alloy and cemented with either of the different resin cements was trimmed into a mini-dumbbell shape for tensile testing. The fractured surfaces and characterization of the dentin-cement interface of bonded specimens were investigated using a Scanning Electron Microscope. A significa...

AIM The aim of this report is to present five-year follow-ups of two different applications for the use of direct laminate resin-based composite veneers to improve esthetics. BACKGROUND Defects in the maxillary anterior teeth, such as enamel hypoplasia and peg lateral, can present esthetic challenges. Furthermore, a treatment plan that can be completed in a single appointment is highly desira...

Inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. The present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (PEC) based microparticles containing antibacterials for the treatment of lung infections.Chitosan polyelectrolyte complex...
