Abstract
Persistent bleeding and the absence of alveolar bone stress following tooth loss can hinder socket healing, complicating future dental implant procedures, and potentially leading to neighboring tooth instability. Therefore, developing materials that promote alveolar bone regeneration and possess both hemostatic and osteogenic properties is crucial for preserving the extraction sites. This study introduces a silk-based laponite composite scaffold material with proficient hemostatic and osteogenic functions, and excellent shape-memory properties for efficient extraction- site filling. In vitro studies research demonstrated that the scaffold's inherent negative charge of the scaffold significantly enhanced blood coagulation and thrombin generation. Moreover, its porous structure and slightly rough inner surface promoted blood cell adhesion and, improved the hemostatic performance. Furthermore, the scaffold facilitated stem cell osteogenic differentiation by activating the TRPM7 channel through the released of magnesium ions. In vivo tests using rat models confirmed its effectiveness in promoting coagulation and mandibular regeneration. Thus, this study proposes a promising approach for post-extraction alveolar bone regenerative repair. The composite scaffold material, with its hemostatic and osteogenic capabilities and shape-memory features, can potentially enhance dental implant success and overall oral health.

An Effective Strategy for the Production of Lauric Acid-Enriched Monoacylglycerol via Enzymatic Glycerolysis from Black Soldier Fly (Hermetia illucens) Larvae (BSFL) Oil. Appl Biochem Biotechnol 2021; 193:2781-2792. [PMID: 33871767 DOI: 10.1007/s12010-021-03565-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Accepted: 04/08/2021] [Indexed: 10/21/2022]
Abstract
Here, we developed an efficient strategy for the production of lauric acid-enriched monoacylglycerol (MAG) via enzymatic glycerolysis using black soldier fly (Hermetia illucens) larvae (BSFL) oil. The effects of the substrate molar ratio, reaction temperature, type of immobilized lipase, and organic solvent on the MAG content and conversion degree of BSFL oil were optimized. The maximum substrate conversion rate (97.88%) and MAG content (70.84%) were obtained in a tert-butanol system at 50 °C with a glycerol/BSFL oil molar ratio of 4:1 by using immobilized MAS1 lipase as a catalyst. The MAG content in the purified product reached 97.7%, with lauric acid accounting for 50.2%. Improved oxidation stability was observed after glycerolysis. Overall, this study provides a new strategy for the preparation of lauric acid-enriched MAG from BSFL oil.
