Effect of a modified adhesive system with encapsulated arginine and calcium carbonate on dentin permeability
AbstractTo modify an adhesive system with halloysite clay nanotubes (HNTs) containing arginine and calcium carbonate and to evaluate their cytocompatibility, viscosity and efficacy in reducing dentin permeability. HNTs containing arginine and calcium carbonate were incorporated into the primer and adhesive of a three-step adhesive system (SBMP), and their viscosity was measured. Discs (n = 4/group) were prepared: SBMP (control), HNT-PR (modified primer), HNT-ADH (modified adhesive) and HNT-PR + ADH (modified primer and adhesive) were evaluated regarding cell death and viability. Dentin discs were prepared and random...

Crosslinkable fluorophenoxy ‐substituted poly[bis(octafluoropentoxy) phosphazene] biomaterials with improved antimicrobial effect and hemocompatibility
In this study, two additional fluorinated polyphosphazenes (PPs, defined as LS02 and LS03) with fluorophenoxy-substituted side groups, 4-fluorophenoxy and 4-(trifluoromethyl)phenoxy, respectively, based on X-OFP general structure, were synthesized and applied as coatings on stainless steel. The linkage of fluorophenoxy groups to the P-N backbone of PPs was found to increase the surface stiffness and significantly reduced Staphylococcus bacterial adhesion and inhibited biofilm formation. It also significantly reduced microbial infection compared to OFP, our prior X-OFPs or poly[bis(trifluoroethoxy) phosphazene] (TFE). The b...

Friction reducing ability of a poly ‐l‐lysine and dopamine modified hyaluronan coating for polycaprolactone cartilage resurfacing implants
AbstractFrictional properties of cartilage resurfacing implants should be sufficiently low to limit damaging of the opposing cartilage during articulation. The present study determines if native lubricious molecule proteoglycan 4 (PRG4) can adsorb onto a layer-by-layer bioinspired coating composed of poly-l-lysine (PLL) and dopamine modified hyaluronic acid (HADN) and thereby can reduce the friction between implant and articular cartilage. An ELISA was developed to quantify the amount of immobilized human recombinant (rh)PRG4 after exposure to the PLL-HADN coating. The effect on lubrication was evaluated by comparing the c...

Simple bio ‐inspired coating of ureteral stent for protein and bacterial fouling and calcium encrustation control
In this study, commercial ureteral stent was coated with polydopamine (PDA), formed from self-polymerization of dopamine. The PDA coating was optimized in terms of dopamine concentration, pH, and coating time using response surface methodology. The chosen response parameters for optimization were calcium oxalate (CaC2O4) encrustation and protein adsorption. Optimized PDA coating conditions were determined to be the following: pH  9.0, 2 mg/mL DA, and 3 days coating. The optimized PDA-coated ureteral stent exhibited outstanding resistance against CaC2O4 encrustation, protein fouling, and bacterial adhesion due to its hy...

Preparation, function, and safety evaluation of a novel degradable dermal filler, the cross ‐linked poly‐γ‐glutamic acid hydrogel particles
AbstractPoly- γ-glutamic acid (PGA) is a naturally degradable hydrophilic linear microbial polymer with moisturizing, immunogenic, cross-linking, and hydrogel water absorption properties similar to hyaluronic acid, a biomaterial that is commonly used as a dermal filler. To explore the development feasibility of cross-linked PGA as a novel dermal filler, we studied the local skin response to PGA fillers and the effect of various cross-linking preparations on the average longevity of dermal injection. Injection site inflammation and the formation of collagen and elastin were also determined. PGA hydrogel par ticles prepared...

Silicon nanowire array overcomes chemotherapeutic resistance by inducing the differentiation of breast cancer stem cells
In this study, we report the SiNWA differentiates MCF-7-derived breast CSCs (BCSCs) into non-CSCs by modulating the morphology of cells. In vitro, the differentiated BCSCs lose the stemness properties and thus become sensitive to chemotherapeutic drugs, eventually leading to the death of BCSCs. Therefore, this work suggests a potential approach for overcoming chemotherapeutic resistance. (Source: Journal of Biomedical Materials Research Part B: Applied Biomaterials)

Effect of nano ‐ceramic coating on surface property and microbial adhesion to poly(methyl methacrylate)
AbstractTo improve surface properties of poly(methyl methacrylate) (PMMA) using nano-ceramic coatings and assess microbial adherence after long-term use of a chemical cleanser. Thirty-six PMMA samples were fabricated, polished and coated with a nano-thin TiO2 or mixed TiO2/ZrO2, with uncoated samples as controls. Six samples in each group (n = 12) were soaked in Polident denture cleaner 180 times for 30 min, while six were soaked in deionized water. Surface roughness of PMMA before and after being soaked in Polident was assessed. All samples were subsequently exposed toCandida albicans for 6  h and the adherent cells ...

Fabrication of hydroxyapatite ‐based nano‐gold and nano‐silver‐doped bioceramic bone grafts: Enhanced mechanostructure, cell viability, and nuclear abnormality properties
In this study, nano-gold (nAu) and nano-silver (nAg) were doped at the molar ratios of Molar5 –Molar30 to the Hydroxyapatite (HAp)-based bioceramic bone graft synthesized by the sol–gel method. The effects of nAu and nAg on structural, mechanical, cell viability, and nuclear abnormality of the synthesized bioceramic grafts were evaluated. The chemical and morphological properties of the bone grafts after production were examined through XRD and SEM–EDX analyses and mechanical tests. To determine the biocompatibility of the bone grafts, cell viability tests were performed using human fibroblast cells. In the cytotoxic...

Alkaline earth metals for osteogenic scaffolds: From mechanisms to applications
AbstractRegeneration of bone defects is a significant challenge today. As alternative approaches to the autologous bone, scaffold materials have remarkable features in treating bone defects; however, the various properties of current scaffold materials still fall short of expectations. Due to the osteogenic capability of alkaline earth metals, their application in scaffold materials has become an effective approach to improving their properties. Furthermore, numerous studies have shown that combining alkaline earth metals leads to better osteogenic properties than applying them alone. In this review, the physicochemical an...

Temperature influence on NiFeMo nanoparticles magnetic properties and their viability in biomedical applications
AbstractNiFeMo alloy nanoparticles were synthesized by co-precipitation in the presence of organic additives. Nanoparticles thermal evolution shows that there is a significant increase in the average size (from 28 to 60  nm), consolidating a crystalline structure of the same type as the Ni3Fe phase but with lattice parameter a  = 0.362 nm. Measurements of magnetic properties follow this morphological and structural evolution increasing saturation magnetization (Ms) by 578% and reducing remanence magnetization (Mr) by 29%. Cell viability assays on as-synthesized revealed that nanoparticles (NPs) are not cytotoxic up t...
