A novel stable biomimetic adhesive coating for functionalization of orthodontic brackets against bacterial colonization and white spot lesions.
BMC Oral Health
January 2025
Oral Technology, University Hospital Bonn, 53111, Bonn, Germany.
Background: This study aimed to evaluate the efficacy of polydopamine (PDA) functionalization on orthodontic brackets in inhibiting biofilm formation and promoting surface bioactivity to buffer the acidity of caries-causing bacteria around orthodontic brackets and prevent demineralization. The stability of the coating in artificial saliva (AS) and distilled water was evaluated, along with its effect on pH changes in simulated body fluid (SBF) and distilled water.
Methods: Maxillary incisor orthodontic brackets underwent PDA functionalization using a dopamine hydrochloride solution following a specific protocol.

In this study, we developed calcium alginate-coated nanovesicles derived from macrophage membranes loaded with berberine (Ber@MVs-CA) for the oral treatment of ulcerative colitis (UC). Ber@MVs-CA demonstrates resistance to gastric acid and controlled drug release in the colonic pH environment, while actively targeting sites of ulcerative colitis injury. pH-responsive release of Ber in Ber@MVs-CA was confirmed through in vitro release experiments.

Smart packaging, also known as intelligent packaging, is responsive to external stimuli, moisture, light, oxygen, heat, pH, and bacterial growth. In this study, polyvinyl alcohol/nanochitosan/phycocyanin nanocomposite (PVA/NCH/PC-NC) for fish fillets of Oncorhynchus mykiss rainbow trout coating was prepared. Five treatments were prepared over a period of 14 days (0, 1, 7 and 14 days) under treatments of T: fish coated with PVA/NCH-NC without PC; T, T T and T fish coated with PVA/NCH/PC-NC (0.

Bovine mastitis is the most widespread disease that causes financial loss in the dairy industry. Staphylococcus aureus is a well-researched multidrug-resistant opportunistic bacterium that is frequently linked to subclinical mastitis and causes significant economic losses. A further problem in the management of S.

Background: For patients with osteoporosis and rotator cuff tears, there is still no consensus on current treatment methods. The material, structure, and number of anchors have important effects on the repair outcome.
Purpose: To investigate the use of chitosan quaternary ammonium salt-coated nickel-titanium memory alloy (NTMA) anchors to treat rotator cuff injury in shoulders with osteoporosis in a rabbit osteoporosis model.
