Synthesis of silver core-shell nanoparticles and their influence on an experimental resin endodontic sealer: An in vitro analysis. Int Endod J 2023; 56:289-303. [PMID: 36314859 DOI: 10.1111/iej.13859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Revised: 09/29/2022] [Accepted: 10/26/2022] [Indexed: 11/05/2022]
Abstract
AIM To avoid root canal recontamination and endodontic treatment failure, endodontic sealers with antibacterial activity could be an alternative. Silver nanoparticles have antibacterial activity and this study aimed to synthesize Ag@SiO2 nanoparticles, incorporate them into an experimental endodontic resin sealer and evaluate their influence on physicochemical and biological properties. METHODOLOGY Ag@SiO2 nanoparticles were produced using the sol-gel process, based on the Stöber method. The particles were characterized in terms of their chemical structure by Fourier transform-infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), UV-Vis spectral analysis, scanning electron microscopy, and transmission electron microscopy, where the particle morphology and diameter were analysed. A dual-cured experimental endodontic resin sealer was formulated using 70 wt% UDMA, 15 wt% GDMA, and 15 wt% BisEMA. The photoinitiators were added separately in two pastes. The Ag@SiO2 nanoparticles were incorporated into the endodontic sealer at the concentrations of 2.5 wt%, 5 wt%, and 10 wt%, and a control group without nanoparticles was also formulated. The endodontic sealers were evaluated for their flow, film thickness, degree of conversion, softening in solvent, radiopacity, cytotoxicity and antibacterial activity immediately and after 9 months in water storage. RESULTS Silver was detected in the chemical characterization of Ag@SiO2 that presented a spheric regular shape and average 683.51 nm ± 93.58 diameter. Sealers presented adequate flow and film thickness while radiopacity values were below the ones required by ISO 6876. All groups underwent softening after immersion in a solvent. The 10 wt% groups showed a higher loss of subsurface hardness (∆KHN%). No reduction in cell viability was observed. Enterococcus faecalis viability in biofilm was reduced in 10 wt% groups after 24 h and 9 months. CONCLUSION The addition of 10 wt% Ag@SiO2 reduced E. faecalis viability at immediate and longitudinal analysis while maintaining the physicochemical properties of developed sealers.

Abstract
Owing to the diverse composition, adjustable performance, and synergistic effect among components, core–shell micro/nanoparticles have been widely applied in the field of tribology in recent years. The strong combination with the matrix and the good dispersion of reinforcing fillers in the composites could be achieved through the design of core–shell structural particles based on the reinforcing fillers. In addition, the performance of chemical mechanical polishing could be improved by optimizing the shell material coated on the abrasive surface. The physical and chemical state of the core–shell micro/nanoparticles played important effects on the friction and wear properties of materials. In this paper, the synthesis methods, the tribological applications (acted as solid/liquid lubricant additive, chemical mechanical polishing abrasives and basic units of lubricant matrix), and the functionary mechanisms of core–shell micro/nanoparticles were systematically reviewed, and the future development of core–shell micro/nanoparticles in tribology was also prospected.

Abstract
A novel nanocrystals delivery system of parthenolide (PTL) was designed to combined application with sorafenib (Sora) for advanced hepatocellular carcinoma (HCC) therapy, attempting to not only improve the poor aqueous solubility of PTL, but also enhance the synergistic therapeutic effects with Sora. The PTL nanocrystals (PTL-NCs) were prepared by precipitation-high-pressure homogenization method. The formed PTL-NCs with rod morphology possessed size of 126.9 ± 2.31 nm, zeta potential of -11.18 ± 0.59 mV and drug loading of 31.11 ± 1.99%. Meanwhile, PTL in PTL-NCs exhibited excellent storage stability and sustained release behavior. The combination therapy of Sora and PTL-NCs (Sora/PTL-NCs) in vitro for HepG2 cells presented superior therapeutic effects over that of individual PTL and Sora on intracellular uptake, cell proliferation inhibition and migration inhibition. Meanwhile the strongest anti-tumor effect with 81.86% inhibition rate and minimized systemic toxicity of Sora/PTL-NCs in vivo were obtained on tumor-bearing mice compared with that of PTL (48.84%) and Sora (58.83%). Thus, these findings suggested that PTL-NCs as an effective delivery system for the synergistically used with Sora to gain an optimal response against HCC, for referenced in the industrialization of nanocrystals products for intravenous administration.

Abstract
As one of the most promising noninvasive therapeutic modalities, sonodynamic therapy (SDT) can focus the ultrasound energy on tumor sites located in deep tissue and locally activate the preloaded sonosensitizer to kill tumor cells. However, exploring sonosensitizers with high SDT efficacy and desirable biosafety is still a significant challenge. Herein, we utilized the hydrophilic-hydrophobic self-assembly technology to assemble the hydrophobic organic dye Ce6 and broad spectral anti-cancer agent Paclitaxel with hydrophilic organic dye IR783 to generate a nanoscale sonosensitizer, Ce6-PTX@IR783, without the introduction of extra nanomaterials into the fabrication to guarantee high therapeutic biosafety and further potential clinical translation. The constructed nanodrug was endowed with an external ultrasound-activatable chemo-sonodynamic effect and photoacoustic imaging performance via integrating multiple moieties into one nanosystem. Ce6 could enhance the sonodynamic effect, while PTX exerted a chemotherapeutic effect, and IR783 was applied to increase tumor-specific accumulation and assist in fulfilling photoacoustic imaging. In particular, the small particle size (70 nm) of Ce6-PTX@IR783 contributed to the increased tumor accumulation via the enhanced permeability and retention effect. The high synergistically chemo-sonodynamic therapeutic efficacy has been successfully demonstrated in vitro and in vivo, in addition to the demonstrated high biodegradability, biocompatibility and biosafety. This facile self-assembly procedure provides an intriguing strategy for highly efficient utilization of hydrophobic drugs and is liable to realize large-scale production and further clinical translation.

Abstract
Background Prednisolone (PD) is extremely effective for treating rheumatoid arthritis (RA). However, it distributes nonspecifically throughout the body and its use is associated with serious side effects, which promoted us to compound it into a phytomedicine for greater efficacy and safety. Methods We combined PD with curcumin (CU), an effective monomer from traditional Chinese medicine, and human serum albumin (HSA) in a nanoparticulate system (N-PD/CU) to compensate for the poor bioavailability of PD and CU. N-PD/CU was prepared by high-pressure homogenization, and its characteristics were evaluated in vitro. Next, we investigated its toxicity and mechanism of anti-inflammatory to macrophages. Finally, its pharmacokinetics, biodistribution and therapeutic efficacy were assessed in rats with adjuvant-induced arthritis (AIA). Results N-PD/CU showed a narrow size distribution around 150.4 ± 2.4 nm, a polydispersity index of 0.22 ± 0.02 and drug loading efficiency (DLE) of 88.75 ± 1.82% for PD and 85.79 ± 1.43% for CU. N-PD/CU showed sustained release of both drugs in vitro. N-PD/CU had no toxicity to macrophages in vitro on concentrations between 0.1 and 1.2 μmol/mL. In activated macrophages, N-PD decreased levels of pro-inflammatory cytokines, while N-CU increased levels of anti-inflammatory IL-10, and N-PD/CU exhibited best therapeutic effect in vitro, suggesting co-delivery of PD and CU may synergistically control the course of RA. In AIA rats, N-PD/CU accumulated in inflamed joints through the effect of extravasation through leaky vasculature and subsequent inflammatory cell-mediated sequestration (ELVIS effect) in inflammatory lesion and showed higher therapeutic efficacy than single-loaded nanoparticles, either free drug on its own, or a simple mixture of the two drugs. Conclusion This codelivery system based on HSA is a promising platform for combination chemotherapy in RA.

Abstract
In traditional nano drug-delivery systems, the complex chemical bonds between drug and carrier often complicate the preparation process and are less prone to rupture upon entry into the target, which is detrimental to the timely release of the drug. The π-π stacking provides us with a promising alternative as it is a weak interaction between the aromatic rings. Since most antitumor drugs are hydrophobic molecules with complex aromatic π-π-conjugated structures, the construction of self-assembly based on π-π stacking between drugs and carriers has the advantage of improving the stability and drug loading capacity as well as the improvement of hydrophilicity and biosafety. This article introduces the recent advances in π-π stacking-guided nano self-assembly for antineoplastic delivery.

Abstract
Amorphous nanosuspensions (ANSs) enable rapid release and improved delivery of a poorly water-soluble drug; however, their preparation is challenging. Here, using hemoglobin (Hb) as a carrier, ANSs aggregated from paclitaxel (PTX)⁻Hb complexes were prepared to improve delivery of the hydrophobic anti-cancer agent. An affinity study demonstrated strong interaction between Hb and PTX. Importantly, the complexes could aggregate into <300 nm ANSs with high drug loading, which acidic condition facilitated their formation. Furthermore, the ANSs possessed improved cytotoxicity against cancer cells over the crystalline nanosuspensions. Taken together, ANSs aggregated from PTX⁻Hb complexes were developed, which could kill cancer cells with high efficiency.

Abstract
Pharmaceutical drugs with low water solubility have always received great attention within the scientific community. The reduced bioavailability and the need of frequent administrations have motivated the investigation of new drug delivery systems. Within this context, drug carriers that release their payload in a sustained way and hence reduce the administration rate are highly demanded. One interesting strategy to meet these requirements is the entrapment of the drugs into gels. So far, the most investigated materials for such drug-loaded gels are derived from polymers and based on covalent linkages. However, over the last decade the use of physical (or supramolecular) gels derived from low molecular weight compounds has experienced strong growth in this field, mainly due to important properties such as injectability, stimuli responsiveness and ease of synthesis. This review summarizes the use of supramolecular gels for the encapsulation and controlled release of small therapeutic molecules.

Abstract
Polyglycidol-based nanohydrogels (nHGs) have been prepared by optimizing the use of liposome master templates resulting in a high-yielding and more practical one-pot process to provide materials capable of carrying drugs of adverse chemical nature. The nanogels prepared with the one-pot method showed favorable kinetics for the release of either Nile Red (NR) or lysozyme (LYS), loaded with gel precursors such as semi-branched poly(glycidol allylglycidyl ether), PEG dithiol (1KDa), a free radical initiator and liposomal lipids at the liposome formation step. This process is superior to a comparable step-wise traditional approach and circumvents loading of the gel precursors with the hydrophilic drug into preformed liposome templates. A thiol-ene crosslinking reaction accomplishes the formation of the nanonetwork resulting in nHGs prepared in the traditional step-wise (nHG-SW) approach and the one-pot (nHG-OP) process. Both nanogel networks were characterized in terms of particle size and zeta (ζ) potential with average values of 148nm±39nm and -25.9mV±9.2 for the nHG-SW and 132nm±32 and -23.1mV±9.7 for the nHG-OPs. Loading efficiency for both of the nanogels with NR was determined by spectrophotometry to be 28% (nHP-SW) and 31% (nHP-OP). The LYS loading was based on the target loading of 10μg/mg for both nanogels found to be 84% and 86% for the nHG-SW and nHP-OP, respectively. As proof of concept for combination drug delivery, the in vitro release of both drug mimics, NR and LYS, were monitored under physiologically relevant conditions by an optimized dialysis method. The implementation of the multi-functional and semi-branched polyglycidol is recognized as the main contributor for the observed highly controlled release of proteins that are otherwise rapidly released from common PEG-based nanogel networks. Furthermore, the one-pot process led to be the most favorable drug delivery system based on the release kinetics pointing to a denser polymer network.

Abstract
Nanogels are nanosized crosslinked polymer networks capable of absorbing large quantities of water. Specifically, smart nanogels are interesting because of their ability to respond to biomedically relevant changes like pH, temperature, etc. In the last few decades, hybrid nanogels or composites have been developed to overcome the ever increasing demand for new materials in this field. In this context, a hybrid refers to nanogels combined with different polymers and/or with nanoparticles such as plasmonic, magnetic, and carbonaceous nanoparticles, among others. Research activities are focused nowadays on using multifunctional hybrid nanogels in nanomedicine, not only as drug carriers but also as imaging and theranostic agents. In this review, we will describe nanogels, particularly in the form of composites or hybrids applied in nanomedicine.

Abstract
Background Rheumatoid arthritis (RA), induced by the prolonged inappropriate inflammatory responses, is one of the most prevalent of all chronic inflammatory joint diseases. Curcumin (CM), a yellow hydrophobic polyphenol derived from the herb turmeric, has various pharmacological activities against many chronic diseases and acts by inhibiting cell proliferation and metastasis and downregulating various factors, including nuclear factor kappa B, interleukin-1β and TNF-α. Given the pathogenesis of RA, we hypothesized that the drug also has antiarthritic effects. The aims of the present study included the following: 1) examining the therapeutic effect of CM administered via intravenous (iv) injection on RA and 2) formulating the drug into oil–water nanoemulsions (Ns) to overcome the low oral bioavailability of CM and achieve oral delivery of the drug. Methods The effect of CM administered through iv injection on adjuvant-induced arthritis in rats was studied in terms of paw swelling, weight indices of the thymus and spleen, and pathological changes in nuclear factor kappa B expression and inflammatory cytokines. Methotrexate was used as a positive control. The CM-Ns were prepared using a high-pressure homogenizing method and characterized with respect to the particle size and morphology. The stability of the CM-Ns in simulated gastrointestinal (GI) fluids and in vitro release were also investigated. A pharmacokinetic study of the CM-Ns and suspensions in which the plasma levels were determined using an high performance liquid chromatography method and the pharmacokinetic parameters were calculated based on a statistical moment theory was also performed in rats. Results CM administered via iv injection had a therapeutic effect on RA similar to methotrexate. CM-Ns with a diameter of approximately 150 nm were successfully prepared, and the drug was well encapsulated into the Ns without degradation in simulated GI conditions. The area under the curve (AUC) and Cmax for the CM-Ns were more than threefold greater than those for the suspensions; moreover, similar decreases in the levels of TNF-α and interleukin-1β in both synovial fluid and blood serum were obtained from oral administration of CM-Ns and iv injection. Conclusion CM was an effective antiarthritic agent, and the present N formulation appeared to be a promising system that allowed RA therapy with CM to be converted from iv to oral administration.

Abstract
A prodrug-based nanosystem obtained by formulating prodrug and nanotechnology into a system is one of the most promising strategies to enhance drug delivery for disease treatment. Herein, we report a new nanosystem based on HA-PTX conjugates (HA-PTX Ns), which penetrated across cell membranes into cytosol, thus enhancing paclitaxel (PTX) delivery. HA-PTX Ns were successfully obtained based on HA-PTX, and their average particle size was approximately 200 nm. Importantly, unlike other prodrug-based nanosystems, HA-PTX Ns obtained cellular entry without entrapment within the lysosomal-endosomal system by using pathways including clathrin-mediated endocytosis, microtubule-associated internalization, macropinocytosis and cholesterol-dependence. Due to significant accumulation in tumors, HA-PTX Ns had more than a 4-fold decrease in tumor volume on day 14 in contrast with PTX alone. In conclusion, HA-PTX Ns could enter cells, bypass the lysosomal-endosomal system and improve PTX delivery.

An ultrasensitive LC-MS/MS method with liquid phase extraction to determine paclitaxel in both cell culture medium and lysate promising quantification of drug nanocarriers release in vitro.

Abstract
The quantification of paclitaxel, a chemotherapy drug used to treat different types of cancers, has been performed from complete cell culture medium and cell lysate samples using a simple liquid-liquid extraction procedure in conjunction with liquid chromatography tandem mass spectrometry (LC-MS/MS). A simple sample preparation using methanol and acetic acid as a weaker acid was applied to avoid paclitaxel destruction and to achieve recovery exceeding 80 % from both matrices spiked with paclitaxel and docetaxel used as internal standard. This rapid, simple, selective and sensitive method enabled the quantification of paclitaxel within the linear range of 1-250nM in culture medium and 5-250nM in cell lysate. The lower limit of quantification was achieved in cell culture medium and cell lysates at 0.2 and 1pmol, respectively. This method was successfully applied to human non-small cell lung carcinoma cells (A549 cells) in order to quantify the amount of paclitaxel in both cell culture medium and lysate after incubation with 5, 50 and 100nM of paclitaxel. This ultra-sensitive method promises the quantification of ultra-low concentrations of paclitaxel released from any nanocarriers, allowing the determination of the kinetic profile of drug release, which is an essential parameter to validate the use of nanocarriers for drug delivery in cancer therapy.
