Paediatric Melanonychia: Diagnosis and Management
JEADV Clinical Practice, EarlyView.ABSTRACT Longitudinal melanonychia (LM) in children presents unique diagnostic and management challenges that cannot be adequately addressed by applying adult‐based criteria. Unlike in adults, there are no validated clinical, dermoscopic or histopathologic criteria for predicting nail unit melanoma in the paediatric population.

Med Research, EarlyView.This review details a three‐stage paradigm shift for tumor‐reactive CD8+ T‐cell identification: decoding transcriptomic states, deciphering clonal functional efficacy, and molecular‐level therapeutic TCR design. Addressing translational hurdles and generative AI “scientific blind spots”—such as missing catch bonds—we present a visionary roadmap.

Journal of Animal Ecology, EarlyView.Using novel approaches of Hill‐number based and coverage‐standardized dissimilarity metrics and community‐weighted traits, we show that tiger moth communities exhibit various traits prone to land‐use intensity and undergo a complex and non‐linear response to tropical rainforest recovery, corroborating recent findings on biotic differentiation (Keck et ...

Journal of Ginseng Research, 2017 Background: UV-B-exposed keratinocytes secrete various paracrine factors. Among these factors, basic fibroblast growth factor (bFGF) stimulates the proliferation of melanocytes. Ginsenosides, the major active compounds of ginseng, are known to have broad
