Characterizing the transformation near indents and cracks in clinically used dental yttria-stabilized zirconium oxide constructs
Abstract: Objectives: Tetragonal zirconia polycrystal (TZP) materials are widely used for full ceramic partial dentures, even though their mechanical properties might change during service. A key property for the durability of the constructs is thought to be an inhibition of crack propagation by phase transformation toughening. Because dental prosthesis are ground and polished for adjustment purposes, it is important to understand the effects of mechanical surface treatments, on localized transformation and around the propagating cracks.Methods: Sintered samples of commercially available 3mol-% Yittria-doped TZP were groun...

Novel dental adhesives containing nanoparticles of silver and amorphous calcium phosphate
The objectives of this study were to incorporate nanoparticles of silver (NAg) and nanoparticles of amorphous calcium phosphate (NACP) into adhesive for the first time, and to investigate the effects on dentin bond strength and plaque microcosm biofilms.Methods: Scotchbond multi-purpose adhesive was used as control. NAg were added into primer and adhesive at 0.1% by mass. NACP were mixed into adhesive at 10%, 20%, 30% and 40%. Microcosm biofilms were grown on disks with primer covering the adhesive on a composite. Biofilm metabolic activity, colony-forming units (CFU) and lactic acid were measured.Results: Human dentin she...

A six-year prospective randomized study of a nano-hybrid and a conventional hybrid resin composite in Class II restorations
The objective of this 6 year prospective randomized equivalence trial was to evaluate the long-term clinical performance of a new nano-hybrid resin composite (RC) in Class II restorations in an intraindividual comparison with its well-established conventional hybrid RC predecessor.Methods: Each of 52 participants received at least two, as similar as possible, Class II restorations. The cavities were chosen at random to be restored with an experimental nano-hybrid RC (Exite/Tetric EvoCeram (TEC); n=61) and a conventional hybrid RC (Exite/Tetric Ceram (TC); n=61). The restorations were evaluated with slightly modified USPHS ...

Poly(styrene oxide)-poly(ethylene oxide) block copolymers: From "classical" chemotherapeutic nanocarriers to active cell-response inducers.
Abstract Two poly(styrene oxide)-poly(ethylene oxide) (PSO-PEO) triblock copolymers with different chain lengths were analyzed as potential chemotherapeutic nanocarriers, and their ability to inhibit the P-glycoprotein (P-gp) efflux pump in a multidrug resistant (MDR) cell line were measured in order to establish possible cell-responses induced by the presence of the copolymer molecules. Thus, EO(33)SO(14)EO(33) and EO(38)SO(10)EO(38) polymeric micelles were tested regarding doxorubicin (DOXO) entrapment efficiency (solubilisation test), physical stability (DLS), cytocompatibility (fibroblasts), release profiles at...

Comparison of Nanocomplexes with Branched and Linear Peptides for SiRNA Delivery.
Abstract Efficient delivery of siRNA remains the greatest technological barrier to the clinical implementation of RNA interference strategies. We are investigating the relationship between the biophysical properties of siRNA nanocomplexes and their transfection efficiency as an approach to the generation of improved formulations. Peptide based formulations are of great interest and so in this study we have compared nanocomplex formulations for siRNA delivery containing linear and branched oligolysine or oligoarginine peptides. Peptides were combined with cationic liposomes in siRNA formulations and compared for tra...

Detection of circulating tumor cells via an X-ray imaging technique
Detailed information on the location and the size of tumor cells circulating through lymphatic and blood vessels is useful to cancer diagnosis. Metastasis of cancers to other non-adjacent organs is reported to cause 90% of deaths not from the primary tumors. Therefore, effective detection of circulating tumors cells (CTCs) related to metastasis is emphasized in cancer treatments. With the use of synchrotron X-ray micro-imaging techniques, high-resolution images of individual flowing tumor cells were obtained. Positively charged gold nanoparticles (AuNPs) which were inappropriate for incorporation into human red blood cells...

Intra‐operative ex vivo photoacoustic nodal staging in a rat model using a clinical superparamagnetic iron oxide nanoparticle dispersion
Abstract The ability to accurately detect tumor metastases in lymph nodes is essential for intra‐operative staging of various malignancies. Histopathological assessment of nodes has the drawback of a time delay before results are available to the surgeon and a likelihood of missing metastases. Photoacoustic (PA) imaging has been shown to possess the potential to detect melanoma metastases in resected in toto lymph nodes based on intrinsic contrast. To extend application of the method to other malignancies, extrinsic contrast for lymphatic mapping is important. We investigate in a metastatic animal model whether clinicall...

Effects of DMSA-Coated Fe3O4 Nanoparticles on the Transcription of Genes Related to Iron and Osmosis Homeostasis
In this article, we checked the effect of 2,3-dimercaptosuccinic acid-coated Fe3O4 nanoparticles on gene expression of mouse macrophage RAW264.7 cells and found that the transcription of several important genes related to intracellular iron homeostasis were significantly changed. We thus speculated that the cellular iron homeostasis might be disturbed by this nanoparticle through releasing iron ion in cells. To verify this speculation, we first confirmed the transcriptional changes of several key iron homeostasis- related genes, such as Tfrc, Trf, and Lcn2, using quantitative PCR, and found that an iron ion chelator, desfe...

Pan-Junctional Sarcoplasmic Reticulum in Vascular Smooth Muscle: Nanospace Ca2+ transport for Site- and Function-specific Ca2+ signalling.
Abstract This review focuses on how smooth muscle sarcoplasmic reticulum (SR), the major releasable Ca(2+) store in these cells, performs its many functions by communicating with the plasma membrane (PM) and other organelles across cytoplasmic nanospaces, defined by membrane-membrane junctions less than 50 nm across. In spite of accumulating evidence in favour of the view that cytoplasmic nanospaces are a pre-requisite for effective control of diverse cellular functions, our current understanding of how smooth muscle cells accomplish site and function specific Ca(2+) signalling remains in its infancy. We first pres...

Lectin Functionalized Nanocarriers for Gene Delivery.
Abstract Gene therapy has emerged as one of the most promising therapeutic methods to treat various diseases. However, inadequate gene transfection efficacy during gene therapy demands further development of more efficient gene delivery strategies. Targeting genetic material to specific sites of action endows numerous advantages over non-targeted delivery. An ample variety of non-viral gene delivery vectors have been developed in recent years owing to the safety issues raised by viral vectors. Non-viral gene delivery vectors containing specific targeting ligands on their surfaces have been reported to enhance the g...

Carbohydrate-PNA and Aptamer-PNA Conjugates for the Spatial Screening of Lectins and Lectin Assemblies.
This study involved the bivalent display both of the weak-affinity sLe(X) ligand and of a high-affinity DNA aptamer. Bivalent presentation led to rather modest (sixfold or less) enhancements of binding when the self-assemblies were targeted against L-selectin on gold nanoparticles. Spatial screening of L-selectin on the surfaces of leukocytes showed higher affinity enhancements (25-fold). This and the distance-activity relationships indicated that leukocytes permit dense clustering of L-selectin. PMID: 23292704 [PubMed - in process]

The marine polyketide myriaporone 3/4 stalls translation by targeting the elongation phase.
Abstract Myriaporone 3/4, a cytotoxic polyketide, has been reported as an inhibitor of eukaryotic protein synthesis. However, the mechanism by which it inhibits translation was unknown. Here we show that myriaporone 3/4 stalls protein synthesis in the elongation phase by inducing phosphorylation of eukaryotic elongation factor 2. The phosphorylation results from direct binding of myriaporone 3/4 to eukaryotic elongation factor 2 kinase. Our study also shows that myriaporone 3/4 in the nanomolar range inhibits in vitro tube formation by endothelial cells without being cytotoxic. In general, myriaporone 3/4 was at le...
