In this case report, a male patient desired a fixed implant prosthesis to replace his failing dentition and tooth-supported fixed and removable appliances. Utilizing a dentofacial analyzer, facial reference glasses, intraoral scans, and CBCT scans, the clinician was able to plan and complete the implant case in a digital workflow. The case illustrates a method of systematically diagnosing, planning, and staging treatment for a full-mouth implant rehabilitation with immediate function and dramatically improved esthetics.

To assess the anti-gingivitis and anti-plaque efficacy of a novel bioavailable stannous fluoride (SnF2) dentifrice to a negative control.

This was a 12-week randomized, controlled, double-blind, two-treatment, parallel group clinical study. One hundred generally healthy adults with evidence of plaque and gingivitis were enrolled into the study. Subjects were randomly assigned to one of two dentifrice treatments (1) novel SnF2 dentifrice containing the amino acid glycine as a stabilizing chelant (Procter and Gamble) or (2) a negative control sodium monofluorophosphate dentifrice. Gingivitis was assessed using the Löe-Silness Gingivitis Index (LSGI) at baseline, Week 1, and Week 12 while plaque was evaluated according to the Turesky Modification of the Quigley-Hein Plaque Index at baseline and Week 12.

One hundred subjects completed the trial. Subjects using the novel SnF2 dentifrice demonstrated statistically significantly fewer bleeding sites and a lower LSGI score versus those using the negative controudy.This case report describes the nonsurgical endodontic management of a distolingual floor perforation in a mandibular first molar using an internal matrix and mineral trioxide aggregate (MTA) cement. The pulp chamber was properly cleaned, and after placement of a synthetic collagen material that served as a barrier at the level of furcation, MTA was used to repair the perforation defect. Root canal treatment was completed and the tooth was restored with a composite restoration followed by a porcelain-fused-to-metal crown.The enterobacterial common antigen (ECA), a three-sugar repeat unit polysaccharide produced by Enterobacteriaceae family members, impacts bacterial outer membrane permeability, and its biosynthesis affects the glycan landscape of the organism. ECA synthesis impacts the production of other polysaccharides by reducing the availability of shared substrates, the most notable of which is the 55-carbon polyisoprenoid bactoprenyl phosphate (BP), which serves as a carrier for the production of numerous bacterial glycans including ECA, peptidoglycan, O-antigen, and more. Here, using a combination of in vitro enzymatic synthesis and liquid chromatography-mass spectrometry (LC-MS) analysis of bacterial lysates, we provide biochemical evidence for the effect on endogenous polyisoprenoid pools from cell culture that arises from glycan pathway disruption. In this work, we have cloned and expressed each gene involved in ECA repeat unit biosynthesis and reconstituted the pathway in vitro, providing LC-MS characterized standards for the investigation of cellular glycan-linked intermediates and BP. We then generated ECA deficient mutants in genes associated with production of the polysaccharide, which we suspected would accumulate materials identical to our standards. We found that indeed accumulated products from these cells were indistinguishable from our enzymatically prepared standards, and moreover we observed a concomitant decrease in cellular BP levels with each mutant. This work provides the first direct biochemical evidence for the sequestration of BP upon the genetic disruption of glycan biosynthesis pathways in bacteria. This work also provides methods for the direct assessment of both the ECA glycan, and a new understanding of the dynamic interdependence of the bacterial polysaccharide repertoire.Despite progress on DNA-assembled nanoparticle (NP) superstructures, their complicated synthesis procedures hamper their potential biomedical applications. Here, we present an exceptionally simple strategy for the synthesis of single-stranded DNA (ssDNA) assembled Fe3O4 supraparticles (DFe-SPs) as magnetic resonance contrast agents. Unlike traditional approaches that assemble DNA-conjugated NPs via Watson-Crick hybridization, our DFe-SPs are formed with a high yield through one-step synthesis and assembly of ultrasmall Fe3O4 NPs via ssDNA-metal coordination bridges. We demonstrate that the DFe-SPs can efficiently accumulate into tumors for sensitive MR imaging. By virtue of reversible DNA-metal coordination bridges, the DFe-SPs could be disassembled into isolated small NPs in vivo, facilitating their elimination from the body. This work opens a new avenue for the ssDNA-mediated synthesis of superstructures, which expands the repertoire of DNA-directed NP assembly for biomedical applications.Iron minerals are important soil components; however, little information is available for the transformation of antibiotics on iron mineral surfaces, especially under limited moisture conditions. In this study, we investigated the catalytic performance of four iron minerals (maghemite, hematite, goethite, and siderite) for the hydrolysis of chloramphenicol (CAP) antibiotic at different moisture conditions. this website All the iron oxides could efficiently catalyze CAP hydrolysis with the half-lives 10 wt % due to the competition of water molecules for surface reactive sites. For siderite, the CAP hydrolysis was resistant to excessive surface water. A bidentate H-bonding interaction mechanism would account for CAP hydrolysis on siderite. The results of this study highlight the importance of surface moisture on the catalytic performance of iron minerals. The current study also reveals a potential degradation pathway for antibiotics in natural soil, which has been neglected before.We report the deposition of cubic copper nanoparticles (Cu NPs) of varying size and particle density on silicon laser-induced periodic surface structures via reactive laser ablation in liquid (RLAL) using intense femtosecond laser pulses. link2 Two syntheses were compared (1) simultaneous deposition, wherein a silicon wafer was laser-processed in aqueous Cu(NO3)2 solution and (2) sequential deposition, wherein the silicon wafer was laser-processed in water and then exposed to aqueous Cu(NO3)2. Only simultaneous deposition resulted in high Cu loading and cubic Cu NPs deposited on the surface. The solution pH, Cu(NO3)2 concentration, and sample translation rate were varied to determine their effects on the size, morphology, and density of Cu NPs. Solution pH near ∼6.8 maximized Cu deposition. The Cu(NO3)2 concentration affected the Cu NP morphology but not the size or Cu loading. The sample translation rate most significantly affected the Cu loading, particle size, and particle density. The observed synthesis parameter dependence of these Cu NP properties resembles results by electrodeposition to grow Cu NPs on silicon surfaces, which suggests that Cu NP deposition by RLAL follows a mechanism similar to electrodeposition.A high-temperature air-stable solar selective absorber (SSA) based on TiW-SiO2 cermet is prepared by the co-sputtering method. The obtained SSA shows remarkable stability in spectrum, structure, and chemistry after air-annealing at 700 °C, demonstrating its resistance against air erosion at high temperature. Comparing with W-SiO2-based SSA, the addition of the Ti element is proved to be effective in enhancing the thermal stability of SSA. Nevertheless, as the temperature increases to 750 °C, perfectly round cavities appear and induce the deterioration of the coating. link3 A phase transformation from α-W to β-W is found at the interface of TiW/HMVF (high metal volume fraction layer) during deposition. Consequently, the inverse phase transformation from β-W to α-W at above 750 °C results in small vacancies at the interface, being the incentive of cavity generation. Afterward, the violent morphological changes of oxidized TiW accelerate the cavities expansion. To enhance its tolerance ability of service temperature, a Cr barrier layer is introduced to prevent the diffusion of oxygen into the TiW layer. Therefore, the optimal SSA performs stably at 800 °C and the failure temperature is elevated to 850 °C, revealing that the air-stable TiW-SiO2-based SSA has outstanding potential in high-temperature photothermal conversion.Ab initio molecular dynamics (MD) with hybrid density functionals and a plane wave basis is computationally expensive due to the high computational cost of exact exchange energy evaluation. Recently, we proposed a strategy to combine adaptively compressed exchange (ACE) operator formulation and a multiple time step integration scheme to reduce the computational cost significantly [J. Chem. Phys. 2019, 151, 151102 ]. However, it was found that the construction of the ACE operator, which has to be done at least once in every MD time step, is computationally expensive. In the present work, systematic improvements are introduced to further speed up by employing localized orbitals for the construction of the ACE operator. By this, we could achieve a computational speedup of an order of magnitude for a periodic system containing 32 water molecules. Benchmark calculations were carried out to show the accuracy and efficiency of the method in predicting the structural and dynamical properties of bulk water. To demonstrate the applicability, computationally intensive free-energy computations at the level of hybrid density functional theory were performed to investigate (a) methyl formate hydrolysis reaction in neutral aqueous media and (b) proton-transfer reaction within the active-site residues of the class C β-lactamase enzyme.Vascularization is the main obstacle for the bone tissue engineering strategies since the defect size is generally large. Incorporation of angiogenic factors is one of the strategies employed in order to accelerate vascularization and improve bone healing. In this study, a biphasic scaffold consisting of fibrous poly(lactide-co-glycolide) (PLGA) and poly(lactide-co-glycolide)-block-poly(ethylene glycol)-block-poly(lactide-co-glycolide) (PLGA-PEG-PLGA) hydrogel loaded with vascular endothelial growth factor-A (VEGF) inducer, GS4012, was constructed. Mesenchymal stem cells isolated from rat bone marrow (rBMSCs) were used for differentiation into osteogenic cells, and endothelial cells isolated from rat peripheral blood (rPBECs) were used to test the in vitro endothelial cell recruitment. The biphasic scaffold was tested for cell proliferation, ALP expression, VEGF induction, expression of osteogenic genes by rBMSCs, and recruitment of rPBECs in vitro and for improved bone healing and vascularization in vivo on critical size rat cranial defects.
