Resveratrol supplementation as a non-surgical treatment in periodontitis and related systemic conditions.

Periodontitis is a chronic inflammatory disease of the oral cavity that represents a significant public health problem, especially in geriatric populations. Indeed, periodontal pathogens like Porphyromonas gingivalis (P. gingivalis), the primary pathogen involved in the initiation and progression of periodontitis, can enter the bloodstream and unleash an inflammatory storm both local (mouth) and systemically, becoming a substantial contributor to the onset of disparate age-related conditions, such as cardiovascular and neurodegenerative diseases, diabetes and cancer. Resveratrol is a polypheno

Curcumin-Based Universal Grafting of Poly(OEGMA) Brushes and Their Antibacterial Applications.

Catechol and/or pyrogallol groups are recognized as crucial for the formation of polyphenol coatings on various substrates. Meanwhile, studies on polyphenolic molecules that do not contain such groups are relatively rare. The key molecule in turmeric-based universal (i.e., substrate-independent) coatings is curcumin, which contains no catechol or pyrogallol groups. As chemically reactive hydroxyl groups would remain after curcumin coating, it is hypothesized that curcumin coating can serve as a reactive layer for controlling interfacial properties. In this study, a curcumin-based surface modif
