Six patients with rheumatoid arthritis (eight eyes) presented with small paracentral perforating corneal ulcers in otherwise quiet eyes. Initial management in five patients (seven eyes) consisted of systemic immunosuppression and therapeutic tissue adhesive with a bandage contact lens or tectonic keratoplasty. Ulceration recurred in all of these eyes, and recurrent ulcers treated with repeat tectonic keratoplasty or therapeutic tissue adhesive and a bandage contact lens all developed recurrent ulceration. The introduction of topical cyclosporine therapy in five eyes with recurrent corneal ulceration was associated with arrest of keratolysis and rapid re-epithelialization of the ulcer in all cases. One corneal ulcer was successfully treated initially with topical cyclosporine, tissue adhesive, and a bandage contact lens. In patients with rheumatoid arthritis and small paracentral corneal ulcerations or perforations, application of tissue adhesive and a bandage contact lens and introduction of topical cyclosporine may be the preferred initial treatment.

Introduction Cosmetic surgery has advanced significantly, with wound closure techniques crucial for determining aesthetic and healing outcomes. Recently, cyanoacrylate glue and subcuticular sutures have gained attention for their unique benefits in cosmetic procedures. Cyanoacrylate glue, a non-invasive tissue adhesive, facilitates faster wound closure with minimal trauma, while subcuticular sutures offer durable, concealed closures, particularly suited for areas under mechanical stress.

Regenerating periodontal bone defect surrounding periodontal tissue is crucial for orthodontic or dental implant treatment. The declined osteogenic ability of periodontal ligament stem cells (PDLSCs) induced by inflammation stimulus contributes to reduced capacity to regenerate periodontal bone, which brings about a huge challenge for treating periodontitis. Here, inspired by the adhesive property of mussels, we have created adhesive and mineralized hydrogel microspheres loaded with traditional compound cordycepin (MMS-CY).

Basic dyes are highly toxic and have adverse effects on humans such as accelerated heart rate, shock, cyanosis, and tissue necrosis upon ingestion or skin contact. Efficient removal of basic dye pollutants from wastewater is therefore essential for the protection of the environment and human health. Biomolecules exhibit excellent dye removal performance in terms of removal capacity, selectivity, and rate.

Delayed wound healing remains a major challenge in biomedical research, often leading to complications such as scarring, acute trauma, and chronic diseases. Effective wound management is crucial for enhancing treatment outcomes, preventing complications, and promoting tissue regeneration. In response to this need, a variety of polymeric biomaterials have been developed.

The weak cohesive strength of tissue adhesives hinders their practical applications. To overcome this challenge, we develop a green bio-adhesive that balances both cohesion and adhesion, drawing inspiration from the natural adhesion mechanisms of mussels. This bio-adhesive, referred to as OTS, was ingeniously crafted through the co-assembly of multi-surface-charged chitin nanofibers (OAChN) and tannic acid (TA), integrated with silk fibroin (SF), resulting in a material with enhanced cohesive strength and robust adhesive properties.
