Cross-linked polyethylenes are being marketed by orthopaedic manufacturers to address the problem of osteolysis caused by polyethylene particulate wear debris. Wear testing of these cross-linked polyethylenes in hip simulators has shown dramatic reduction in wear rate compared with standard ultrahigh molecular weight polyethylene, either gamma irradiated in air or nitrogen - or ethylene oxide-s...

In this study, magnetic iron oxide nanoparticles (Fe3O4) with the size range of 20-30 nm were prepared by the modified controlled chemical co-precipitation method from the solution of ferrous/ferric mixed salt-solution in alkaline medium. In this process polyethylene glycol was used as a surfactant to prevent the solution from agglomeration. The prepared magnetic nanoparticles were characterize...

Multiple factors have been identified as contributing to polyethylene wear and debris generation of the acetabular lining. Polyethylene wear is the primary limiting factor in the functional behavior and consequent longevity of a total hip arthroplasty (THA). This retrospective study reviewed the clinical and radiographic data of 77 consecutive THAs comparing in vivo polyethylene wear of two sim...

In this study, mesoporous silica nanoparticles (MSNs) were used to prepare an oral push-pull osmotic pump. Fenofibrate, the selected model drug, was firstly loaded into the MSNs, followed by a suspending agent consisting of a drug layer of push-pull osmotic pump. Fenofibrate-loaded MSNs were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), nitrogen ad...

We report the fabrication of a coaxial electrospun scaffold with bioactive molecule in core and protein conjugated at surface. To construct scaffold, we chose polyethylene oxide for material polycaprolactone/Jeffamine blend shell.

Sorption of ethylene oxide during and after gaseous sterilization is influenced by numerous factors. It was found that ethylene oxide desorption not only depends on material to be fumigated but also to a considerable degree on the wrapping material. Although polyethylene, polyamide (nylon), polytetrafluoroethylene (Teflon), silicone, aluminum, and glass beads contained no quantities of ethylene...

Polyethylene oxide stabilized magnetic nanoparticles (PEO-MNPs) bio-functionalized with glycoconjugate (Neu5Ac(α2-3)Gal(β1-4)Glcβ-sp) (GM3-MNPs) are synthesized using click chemistry. Interaction of GM3-MNPs with Enterotoxigenic Escherichia coli (ETEC) strain K99 (EC K99) is investigated using different microscopic techniques. Our results suggest that GM3-MNPs can effectively act as non-antibio...

We have used the flow characteristics of an electrospinning jet to elongate and fix DNA molecules. We embedded and observed fluorescently labeled lambda bacteriophage DNA molecules in polyethylene oxide nanofibers. The embedded DNA molecules were imaged using fluorescence microscopy and found to be stretched to lengths approaching the full dyed contour length.

Graphene oxide nanoribbons (GONRs) were covalently functionalized with an antibody using polyethylene glycol (PEG) as a linker to produce a novel probe for surface enhanced laser desorption/ionization mass spectrometry (SELDI MS). This probe provides a highly sensitive and selective platform for enrichment and MS detection of small molecules in complex media.
