J Biomed Mater Res A 2021; 110:976-983. [PMID: 34908219 DOI: 10.1002/jbm.a.37346] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 11/27/2021] [Accepted: 12/04/2021] [Indexed: 12/12/2022]
Abstract
Protein-bound uremic toxins (PBUTs) are significant toxins that are closely related to the prognosis of chronic kidney disease. They cannot be effectively removed by conventional dialysis therapies due to their high albumin binding affinity. Our previous research revealed that cationic liposomes (i.e., polyethyleneimine [PEI]-decorated liposomes) could enhance the clearance of PBUTs via electrostatic interactions. However, the poor biocompatibility (hemolysis) restricted their applications in clinical dialysis treatment. Herein, we produced PEI-anchored, linoleic acid-decorated liposomes (CP-LA liposomes) via the conjugation of PEI to cholesterol chloroformate (Chol-PEI, CP), and linoleic acid (LA) was added to provide liposomal colloidal stability. The CP-LA liposomes outperformed the plain liposomes, demonstrating significantly higher PBUT binding rates and removal rates. In addition, in vitro dialysis simulation verified that the CP-LA liposomes had a better capacity for PBUT clearance than the plain liposomes, especially for PBUTs with a strong negative net charge. Hemolysis and cytotoxicity tests revealed that the biocompatibility of the CP-LA liposomes was better than that of the physically-decorated PEI-liposome. CP-LA liposomes possess great potential for PBUT clearance in clinical dialysis therapy.

Abstract
Mesoporous silica nanoparticles (MSNPs) are a particular example of innovative nanomaterials for the development of drug delivery systems. MSNPs have recently received more attention for biological and pharmaceutical applications due to their capability to deliver therapeutic agents. Due to their unique structure, they can function as an effective carrier for the delivery of therapeutic agents to mitigate diseases progress, reduce inflammatory responses and consequently improve cancer treatment. The potency of MSNPs for the diagnosis and management of various diseases has been studied. This literature review will take an in-depth look into the properties of various types of MSNPs (e.g. shape, particle and pore size, surface area, pore volume and surface functionalisation), and discuss their characteristics, in terms of cellular uptake, drug delivery and release. MSNPs will then be discussed in terms of their therapeutic applications (passive and active tumour targeting, theranostics, biosensing and immunostimulative), biocompatibility and safety issues. Also, emerging trends and expected future advancements of this carrier will be provided.

Abstract
In recent years, it has been found that exosomes can be used as nanocarriers, which can be used in the treatment of tumors by carrying contents. The exosomes are derived from the secretion of the organism's own cells and are characterized by a phospholipid bilayer structure and a small particle size. These characteristics guarantee that the exosomes can carry a wide range of tumor drugs, deliver the drug to the cancer, and reduce or eliminate the tumor drug band. The toxic side effects were significantly eliminated; meanwhile, the therapeutic effects of the drug on the tumor were remarkably improved. This paper reviewed the strategies and drugs presented by different scholars for the treatment of tumors based on the drugs carried by exosomes.

Abstract
Tyrosinase inhibitors could effectively limit the activity of tyrosinase in melanocytes to reduce the excessive synthesis and deposition of melanin. However, low skin permeability and lacking in targeting greatly restricted their application. Herein, ZnO quantum dots were synthesized by gel-sol method and grafted with BQ-788, which have been employed as transdermal and targeting carrier to delivery ellagic acid to melanocytes. Ellagic acid loaded ZnO quantum dots with the size distribution of around 9 nm could targetedly bind to melanocytes and enter the melanocytes by endocytosis within 1 h. The ellagic acid release behavior was controlled by the decreasing of pH via the rapid dissolution of ZnO. When the concentration of BQ-788/EA@ZnO was 12.5 μg/mL, the inhibition rate on tyrosinase activity and melanin deposition were up to 44.23 ± 4.97% and 37.50 ± 5.23%, respectively. In view of their good biocompatibility, they were of great potential in clinically external application for tyrosinase inhibition.

Abstract
OBJECTIVES This study aims to apply electrophoretic deposition (EPD) for occlusion of dentinal tubules in vitro and investigate its effect on tubule occlusion and shear bond strength (SBS). METHODS Charged mesoporous silica nanoparticles (MSNs) were synthesized and characterized through field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), dynamic light scattering (DLS), and Fourier transform infrared (FT-IR) spectroscopy analyses. Thirty-nine sensitive dentin specimens were modeled and assigned randomly to three groups with different treatments (n = 13 each): group 1, immersion in the MSN suspension; and groups 2 and 3, anodic EPD with the specimen on the negative and positive electrode respectively. The effect of dentinal tubule occlusion was evaluated by dentin permeability test (n = 10 each) and FESEM examination (n = 3 each). Moreover, 18 specimens were grouped (n = 6 each) and treated in the same method. A resin stick was bonded onto each of the specimen using a self-etch adhesive (single bond universal) for SBS testing. RESULTS Negatively-charged MSNs were synthesized and characterized as small and well-dispersed particles. After the EPD treatment (group 3), the dentinal tubules were effectively occluded by MSNs, which infiltrated into the tubules at a depth of approximately 7-8 μm and tightly associated with the tubular inwalls. SBS was not significantly different among the three groups (P > 0.05). CONCLUSIONS Synthesized MSNs were deposited into dentinal tubules by EPD treatment without compromising dentin bond strength. CLINICAL SIGNIFICANCE Application of EPD is a new approach for occlusion of dentinal tubules and exhibits potential in the study of dentin hypersensitivity.

Abstract
Although multi-drug synergetic therapy is increasingly important in clinical application, sophisticated delivery systems with the ability to deliver multiple drugs and realize sequential release with independently tunable kinetics at different stages are highly desirable. In this study, a dual-generation mesoporous silica nanoparticle (DAMSN) with three-dimensional dendrimer-like structure as an adaptable dual drug delivery system is developed. The DAMSN was synthesized via a heterogeneous interfacial reaction and was of uniformly spherical morphology (150–170 nm) with dendritic structures and hierarchical pores (inner pore, 3.5 nm; outer pore, 8.3 nm). And the inner generation of DAMSN was modified with 3-aminopropyltriethoxysilane (APTMS). The IBU and BSA as model drugs were loaded into the inner generation via covalent conjugation and the outer generation by electrostatic adsorption, respectively. Intriguingly, DAMSN underwent a rapid bio-degradation for about 4 days, partly due to its center-radial dendritic channel structure. The release results showed that IBU was of a typical two-phase release profile with almost zero release in the first 12 h and more sustained release for the following 88 h, while BSA was sustained over a long period of 100 h. Notably, the release behaviors of both drugs can be independently tailored by changing the intrinsic properties of the DAMSN. In addition, DAMSN exhibited good bio-compatibility. These results indicated that the dual-generation, dendrimer-like MSN structure could spatiotemporally present different drugs to realize sequential drug release, and has potential use in the field of tissue engineering and regenerative medicine. The designed DAMSN could simultaneously load IBU and BSA, and realize sequential drug release efficiently.![]()

Abstract
The low efficacy and high toxicity of chemotherapy have been driving increasing attention on development of combined anticancer therapy technique. In the current work, graphene oxide (GO)-hybridized nanogels (AGD) were developed for delivery of an anticancer drug (doxorubicin (DOX)), which simultaneously presented photothermal therapeutic effects against cancer cells. AGD nanogels were fabricated by in situ incorporating GO nanoplatelets into a biodegradable polymer (alginate) via a double emulsion approach using a disulfide molecule as crosslinker, followed by DOX encapsulation via electrostatic interactions. The nanogels released DOX drug in an accelerated way under both acidic and reducible conditions mimicking extracellular tumor microenvironments and intracellular compartments. The stimulative release controllability of the nanogels improved the DOX internalization and long-term drug accumulation inside A549 cells (an adenocarcinoma human alveolar basal epithelial cell line), which, together with their photothermal effect, resulted in a good anticancer cytotoxicity, indicating their promising potential for combinative anticancer therapy.
