Article Abstract
Skin is the largest organ of the body and serves as a barrier against various environmental threats, including ultraviolet (UV) radiation, which could lead to pigmentation and an increased risk of melanoma. Oxidative stress has been identified as a significant factor in UV-induced skin pigmentation, yet there still remain significant challenges in understanding its role . Selenium nanoparticles have exhibited multiple bioactivities in many fields, but their application in skin diseases is limited. In this work, the zebrafish screen was first carried out in a transgene zebrafish larva cocultured with Nano-Se, which demonstrated a whitening effect of Nano-Se on pigmentation caused by UVB exposure . Further study showed that Nano-Se could also boost the effectiveness of tranexamic acid, combined with the whitening effect in relieving UVB-induced skin pigmentation and damage in mice. In a word, the Nano-Se described in this study offers an efficient and practical approach for synthesizing bioactive selenium nanoplatforms, broadening the application of nanoselenium to combat UVB-induced skin damage, and potentially revitalizing research of nanoselenium in various human diseases.

The salt-inducible kinase (SIK) family encompasses three isoforms, SIK1, SIK2, and SIK3, which are members of the AMP-activated protein kinase (AMPK) family of serine/threonine protein kinases. SIK inhibition has emerged as a potential therapeutic approach across multiple indications, as SIKs regulate a diverse set of physiological processes such as metabolism, bone remodeling, immune response, malignancies, skin pigmentation, and circadian rhythm. Within isoform-specific SIK inhibitors there is a need to understand the distinct role of each protein, and here we describe the first SIK1 selective inhibitors.

Nosocomial infections remain a major healthcare challenge, underlining the demand for antimicrobial technologies. Far UV-C (200-235 nm) has emerged as a safer alternative to traditional 254 nm UV-C for microbial reduction on skin and wounds but also in occupied spaces due to its strong germicidal properties and minimal skin penetration. However, studies on humans remain limited.

Background: Erythema, an early visual indicator of tissue damage preceding pressure injuries (PrIs), presents as redness in light skin tones but is harder to detect in dark skin tones. While thermography shows promise for early PrI detection, validation across different skin tones remains limited. Furthermore, most protocols and models have been developed under highly controlled conditions.

Pufferfish exhibit the smallest vertebrate genomes, making them ideal models for investigating evolutionary patterns and processes that affect genome size. While the Takifugu rubripes genome was fully sequenced two decades ago, key evolutionary drivers remain elusive. We sequenced 10 pufferfish genomes and generated 35 transcriptomes and 13 methylomes to understand genomic evolutionary mechanisms.

Objective: We identified a novel mutation in the protein kinase cAMP-dependent type I regulatory subunit α () gene in a Chinese patient presenting with multiple recurrent cardiac myxomas, confirming a diagnosis of Carney complex (CNC). By reviewing the relevant literature, we aimed to enhance our understanding of this condition.
