Population genetics and infection dynamics of Phocanema krabbei and P. decipiens (Nematoda: Anisakidae) in commercially exploited fish from the Northeast Atlantic

This study provides the first comprehensive assessment of *Phocanema krabbei* and *P. decipiens* infections in Northeast Atlantic fish, revealing that *P. krabbei* dominates the region with a single panmictic population, primarily infecting *Lophius* species and preferring muscle tissues, while highlighting significant public health and economic implications for the seafood industry.

Gelsolin: A Potential Prognostic Biomarker Linked to Immune Infiltration in Colon Adenocarcino

This study identifies Gelsolin (GSN) as a downregulated prognostic biomarker in colon adenocarcinoma, demonstrating that its reduced expression correlates with poorer patient survival, significant immune cell infiltration, and decreased serum levels, thereby suggesting its potential utility as a diagnostic marker and neo-antigen for targeted therapy.

Social media use, genotype and adolescent mental health: A social push pattern among girls

Using data from the UK Millennium Cohort Study and a trio design, this study finds that social media use acts as a "social push" that disproportionately harms girls' mental health by elevating risk across the board and compressing genetic differences, particularly among those with a low genetic propensity for poor well-being.

PrPC High Expression Predicts Poor Prognosis and Regulates Gastric Cancer EMT

This study demonstrates that high expression of cellular prion protein (PrPC) drives gastric cancer progression by promoting epithelial-mesenchymal transition (EMT) and correlates significantly with poor prognosis, establishing it as a valuable prognostic biomarker and potential therapeutic target.

Age but not sex modifies lymphoid immune responses in murine sepsis

This study utilizes single-cell RNA sequencing to demonstrate that while both age and sex shape baseline lymphoid composition in murine sepsis, aging uniquely drives distinct transcriptional reprogramming, metabolic shifts, and altered drug response profiles in lymphocytes, whereas sex does not significantly modify the septic immune response.

The Punnai Tree (புன்னை) of Classical Tamil Sangam Poetry: A Botanical Identification of Calophyllum inophyllum L. Through Primary Sources

By synthesizing botanical, geographical, linguistic, and literary evidence from sixteen sources, this paper definitively identifies the coastal Punnai tree of classical Tamil Sangam poetry as *Calophyllum inophyllum* L., distinguishing it from other South Indian *Calophyllum* species that inhabit mountainous regions.
