A scratch assay is a simple wound healing model for assessing cell migration in which a confluent cell layer is scratched to create a scratch zone ("wound") that cells migrate into. Here, we describe a scratch assay exhibiting delayed closure and increased inflammation, which more closely resemble chronic wounds. This delayed scratch closure assay is more relevant for screening compounds and studying delayed wound healing compared with traditional scratch wound assays that more closely resemble acute wounds.

: Chronic skin wounds are characterized by inflammation, persistent infections, and tissue necrosis. The presence of bacterial biofilms prolongs the inflammatory response and delays healing. Ozone is a potent antimicrobial molecule, and many formulations have been used in the advanced therapeutic treatment of chronic wounds.

A 22-year-old woman presented with an ulcer on her right earlobe 2 months ago, with inflammation and enlarged ipsilateral lymph nodes in her neck. She was treated with antibiotics without success and then was referred to an infectious disease specialist. She has a cat at home with sporotrichosis, but without direct contact with the lesion, she did not remember any scratching by the cat.

Acute flaccid paralysis (AFP) case surveillance is pivotal for the early detection of potential poliovirus, particularly in endemic countries such as Ethiopia. The community-based surveillance system implemented in Ethiopia has significantly improved AFP surveillance. However, challenges like delayed detection and disorganized communication persist.

Impairments in the differentiation and migratory capacity of epidermal stem cells (ESCs) are pivotal factors contributing to delayed wound healing. High mobility group box1 (HMGB1) has recently emerged as a potential target for tissue repair. Therefore, we aimed to investigate the role and molecular mechanisms of HMGB1 in ESCs during the wound-healing process.

Decoding visual and auditory stimuli from brain activities, such as electroencephalography (EEG), offers promising advancements for enhancing machine-to-human interaction. However, effectively representing EEG signals remains a significant challenge. In this paper, we introduce a novel Delayed Knowledge Transfer (DKT) framework that employs spiking neurons for attention detection, using our experimental EEG dataset.
