Article Abstract
Alveolar bone loss has long been a challenge in clinical dental implant therapy. Simvastatin (SV) has been demonstrated to exert excellent anabolic effects on bone. However, the successful use of SV to increase bone formation in vivo largely depends on the local concentration of SV at the site of action, and there have been continuing efforts to develop an appropriate delivery system. Specifically, nanostructured lipid carrier (NLC) systems have become a popular type of encapsulation carrier system. Therefore, SV-loaded NLCs (SNs) (179.4 nm in diameter) were fabricated in this study, and the osteogenic effect of the SNs was evaluated in a critical-sized rabbit calvarial defect. Our results revealed that the SNs significantly enhanced bone formation in vivo, as evaluated by hematoxylin and eosin (HE) staining, immunohistochemistry, and a fluorescence analysis. Thus, this novel nanostructured carrier system could be a potential encapsulation carrier system for SV in bone regeneration applications.

Retinal neovascularization is one of the most prevalent fundus neovascular diseases, affecting vision and potentially leading to severe complications, such as retinal detachment or irreversible blindness. Current treatments primarily involve intravitreal injections (IVT) of anti-vascular endothelial growth factor (anti-VEGF) agents. However, such treatment often requires repeated injections, develop incomplete responses, and are associated with adverse effects.

The semiconductor-electrolyte interface with strong electrical tunability offers a platform for tuning nonlinear optical (NLO) processes and achieving giant optical nonlinearities. However, such a demonstration and fundamental mechanistic understanding of electrochemically tuned NLO properties have not been reported. Here, we developed an electrochemical Z-scan system to characterize the evolution of NLO responses in tellurium nanorod films under bias voltage.

Carvacrol (CAR) is a naturally occurring bioactive compound that is chemically unstable, and microencapsulation technology effectively protects its active components. Casein (CS) and chitosan (CH) were used for the first time as carriers to encapsulate CAR, forming highly stable carvacrol microcapsules (CAR@CS-CH). Under conditions of a 1:1 mass ratio of CS to CH and a pH of 5.
