Monitoring wound infection and providing appropriate treatment are crucial for achieving favorable outcomes. However, the time-consuming nature of laboratory culture tests may delay timely intervention. To tackle this challenge, a simple yet effective HDG hydrogel, composed of hydrogen peroxide (H₂O₂), dopamine, and GelMA polymer, is developed for the ultrafast detection and treatment of Staphylococcus aureus (SA) infections.

Inflammation aggravates secondary damage following spinal cord injury (SCI). M1 microglia induce inflammation and exert neurotoxic effects, whereas M2 microglia exert anti-inflammatory and neuroprotective effects. The sine oculis homeobox (SIX) gene family consists of six members, including sine oculis homeobox homolog 1 (SIX1)-SIX6.

Purpose: Corynebacterium species are commensals of human skin and mucous membranes and are recognized as important pathogens in ocular infections. This study investigated the clinical characteristics of Corynebacterium keratitis.
Methods: We retrospectively reviewed cases of bacterial keratitis in which Corynebacterium species were solely isolated from corneal scraping cultures collected at Ehime University Hospital between January 2010 and February 2024.
Low-temperature vacuum evaporation as a novel dehydration process for the long-term preservation of transplantable human corneal tissue.

Globally there is a shortage of available donor corneas with only 1 cornea available for every 70 needed. A large limitation to corneal transplant surgery is access to quality donor tissue due to inadequate eye donation services and infrastructure in many countries, compounded by the fact that there are few available long-term storage solutions for effectively preserving spare donor corneas collected in countries with a surplus. In this study, we describe a novel technology termed low-temperature vacuum evaporation (LTVE) that can effectively dry-preserve surplus donor corneal tissue, allowing it to be stored for approximately 5 years, shipped at room temperature, and stored on hospital shelves before rehydration prior to ophthalmic surgery.
