“…107 Li et al developed a polymer with low toxicity (LP series) and one that was hyperbranched (HP series) as an miRNA transfection system, which was encapsulated in polylactic acid-glycolic acid sustained-release microspheres; the microspheres were further attached to a l -polylactic acid nano-porous scaffold to construct local miRNA. 102,107,108 The sustained release system was degraded at different speeds with polylactic acid-glycolic acids of different molecular weights to achieve sustained release. In this study, miRNA-26a was embedded in this miRNA local sustained release system and implanted into a mouse skull defect model, and showed good ability to promote bone defect repair in situ.…”

With the incidence of different bone diseases increasing, effective therapies are needed that coordinate a combination of various technologies and biological materials. Bone tissue engineering has also been considered as a promising strategy to repair various bone defects. Therefore, different biological materials that can promote stem cell proliferation, migration, and osteoblastic differentiation to accelerate bone tissue regeneration and repair have also become the focus of research in multiple fields. Stem cell therapy, biomaterial scaffolds, and biological growth factors have shown potential for bone tissue engineering; however, off-target effects and cytotoxicity have limited their clinical use. The application of nucleic acids (deoxyribonucleic acid or ribonucleic acid) and nucleic acid analogs (peptide nucleic acids or locked nucleic acids), which are designed based on foreign genes or with special structures, can be taken up by target cells to exert different effects such as modulating protein expression, replacing a missing gene, or targeting specific gens or proteins. Due to some drawbacks, nucleic acids and nucleic acid analogs are combined with various delivery systems to exert enhanced effects, but current studies of these molecules have not yet satisfied clinical requirements. In-depth studies of nucleic acid or nucleic acid analog delivery systems have been performed, with a particular focus on bone tissue regeneration and repair. In this review, we mainly introduce delivery systems for nucleic acids and nucleic acid analogs and their applications in bone repair and regeneration. At the same time, the application of conventional scaffold materials for the delivery of nucleic acids and nucleic acid analogs is also discussed.

“…Vibration is mainly caused by the electromagnetic force of linear motor. When studying vibration problem, the pumping-unit linear motor can be taken a mechanical system, each of which has its own properties like the degree of freedom, the mass matrix, stiffness matrix, damping matrix of the system and so on [6]. The pumping-unit linear motor suffers the radial electromagnetic force.…”

Taking efficient pumping-unit linear motor as the research object in this paper, SOLIDWORK has been used to establish 3D model and analyze multi-physics of the efficient pumping-unit linear motor, including vibration mode, stress analysis and the analysis of temperature field. Through the simulation analysis, getting efficient pumping unit linear motor of the top five order vibration frequency, pressure distribution and temperature distribution, theoretical references are provided for the analysis of the efficient pumping-unit linear motor. The innovation of the article is in coupling analysis of multi-physics.

“…Some ceramic crowns possess good mechanical strength but demonstrate insufficient translucency to match the natural appearance of the human tooth. Some ceramic crowns are too brittle to be used as posterior crowns, which are subjected to a stronger biting force than anterior crowns [3]. Rekow et al [4] reported the following as contributing factors to crown performance: material selection of crown and luting agent, crown thickness, cement space and tooth supporting structure, and whether the tooth has been treated endodontically or a build-up restoration is placed under the crown.…”

All-ceramic dental crown restoration is popular because it results in better aesthetic quality than metal alloy restoration. Ceramics also show superior biocompatibility and inertness to human biological systems. However, clinical experience indicates that all-ceramic crowns are not as durable as their porcelain-fused-to-metal counterparts, particularly on molar teeth. New ceramic biomaterials that combine durability with excellent aesthetic qualities have been developed. In this study, several promising bioceramics for dental crown applications are evaluated and compared. The evaluated parameters include strength of the material, survival rate in clinical performance, and aesthetic quality.
