Chessboard-like Burn Wound Healing Model of Mice Based on Digital Heating Device.

Severe burn injuries are among the most traumatic and physically debilitating conditions, impacting nearly every organ system and resulting in considerable morbidity and mortality. Given their complexity and the involvement of multiple organs, various animal models have been created to replicate different facets of burn injury. Methods used to produce burned surfaces vary among experimental animal models.

Amelogenin-Inspired Autoadaptive Peptide in a Caries Microenvironment Facilitates Long-Term Protection of the Dentin-Pulp Complex.

Dental caries, one of the most prevalent infectious diseases, is the primary contributor to the early loss of natural teeth and is a significant public health issue. Known as the tooth's bioactive core, the dentin-pulp complex (DPCX) comprises tightly connected hard and soft tissues that not only serve as a biological barrier for the inner tooth tissue but also produce reparative dentin following mild disruptions. While efforts to preserve DPCX are numerous, most strategies focus on temporary antibacterial measures, inflammation reduction, or tissue regeneration, lacking a comprehensive, long-lasting solution.

Mineralization promotion and protection effect of carboxymethyl chitosan biomodification in biomimetic mineralization.

Biomimetic mineralization emphasizes reversing the process of dental caries through bio-inspired strategies, in which mineralization promotion and collagen protection are equally important. In this study, carboxymethyl chitosan (CMC) was deemed as an analog of glycosaminoglycan for biomimetic modification of collagen, both of the mineralization facilitation and collagen protection effect were evaluated. Experiments were carried out simultaneously on two-dimensional monolayer reconstituted collagen model, three-dimensional reconstituted collagen model and demineralized dentin model.
