We previously demonstrated that cellular Sloan-Kettering Institute (c-Ski) played a dual role, both promoting wound healing and alleviating scar formation. However, its mechanism and therapeutic effects are not clear, especially compared with widely used treatments, such as basic fibroblast growth factor (bFGF) administration. However, Ski treatment led to an even shorter healing time and a more significant reduction in scar area than bFGF treatment. The mechanism underlying this difference was related to a reduced inflammatory response, more rapid re-epithelialization, less collagen after healing and a greater reduction in the proportion of alpha-smooth muscle actin and SMemb-positive cells after Ski treatment. These results not only confirm that Ski plays a dual role in promoting healing and reducing scarring but also suggest that Ski yields better treatment effects than bFGF, indicating better potential therapeutic effects in wound repair.

Background: Alzheimer's disease (AD) is a neurodegenerative disorder without a cure. Targeting this multifactorial disease by repurposing FDA approved drugs serves as a faster mode of treatment due to its pre-established human safety. We tested terazosin (TZ), an a-1 adrenergic receptor (AR) antagonist and phosphoglycerate kinase-1 (PGK1) activator as having potential to treat AD.

Cezanne-2 (Cez2) is a deubiquitinylating (DUB) enzyme involved in the regulation of ubiquitin-driven cellular signaling and selectively targets Lys11-linked polyubiquitin chains. As a representative member of the ovarian tumor (OTU) subfamily DUBs, it performs cysteine proteolytic isopeptide bond cleavage; however, its exact catalytic mechanism is not yet resolved. In this work, we used different computational approaches to get molecular insights into the Cezanne-2 catalytic mechanism.

Background: Occupational therapists (OTs) play a crucial role in rehabilitation, aiming to improve the lives of individuals with sensory impairment and an increased risk of cognitive decline. Despite being responsible for cognitive screenings on occasion, they have expressed limited confidence in performing these with their clients with visual and/or hearing impairments (VI/HI). To improve this situation, OTs should gain expertise in collaborative sensory rehabilitation.

Obstructive sleep apnea (OSA) is increasingly recognized for its link to idiopathic pulmonary fibrosis (IPF), though the underlying mechanisms remain poorly understood. Histone lysine demethylase 6B (KDM6B) may either prevent or promote organ fibrosis, but its specific role in IPF is yet to be clarified. This study aimed to investigate the function and mechanisms of KDM6B in IPF and the exacerbating effects of OSA.
