Gelatin-Modified Bioactive Glass for Treatment of Dentin Hypersensitivity.
Int J Mol Sci
November 2024
Article Synopsis
- Dentin hypersensitivity occurs when exposed dentin, often due to a lack of enamel, reacts to external stimuli, causing discomfort.
- A new treatment using gelatin-modified bioactive glass (MBG@PDA@Gel) effectively blocks dentin tubules and promotes mineralization, showing better results than the traditional agent Gluma in lab tests.
- Animal studies revealed that MBG@PDA@Gel not only remineralizes demineralized dentin effectively but also remains stable in the oral cavity, enhancing the biocompatibility of the material.
As a broad-spectrum antimicrobial material, ZnO nanoparticles (NPs) offer a novel approach to infected wounds in the clinic; however, it is very necessary to improve the antimicrobial performance of ZnO to satisfy the clinic requirements. In this work, a new antimicrobial hybrid ZnO@PDA/GL13K was prepared by attaching the antimicrobial GL13K peptide on the surface of ZnO NPs via polydopamine (PDA) as a covalent bonding agent, which can enhance the reactive oxygen species (ROS) production and damage the cell wall, showing superior antimicrobial efficacy. Besides, the ZnO@PDA/GL13K hybrid can promote the healing of bacterial infected wounds, with the wound area only remaining 1.

- * Two studies were conducted: one with 154 residents and another with 136 college students in Beijing, both showing that risk preference influences the connection between procedural justice and public policy acceptance.
- * Findings indicate that risk-averse individuals are more affected by uncertainty in their acceptance of public policies than those who are risk-seeking, highlighting the complex interplay between these factors.
Bermuda grass () is notoriously difficult to control with some commonly used herbicides. We cloned a cytochrome P450 gene from Bermuda grass, named , which was found to confer tolerance to multiple herbicides in transgenic . These herbicides include: (1) acetolactate synthase (ALS) inhibitor herbicides nicosulfuron and penoxsulam; (2) p-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting herbicide mesotrione; (3) synthetic auxin herbicide dicamba; (4) photosynthesis inhibitor bentazon.
