Dominance concentration and litter-associated trait shifts in ground-active arthropod assemblages along a recreational-use gradient

This study reveals that in Nanjing's Zijin Mountain, recreational use alters ground-active arthropod assemblages not by reducing total abundance, but by concentrating dominance in specific taxa like ants, reducing diversity, and shifting functional traits and community composition through the degradation of the litter layer.

S100A11 Regulates Tenocyte-Derived Stem Cell Apoptosis via the UCHL3/Bcl- 2/Bax/Caspase3 Signalling Pathway and Influences Tendinopathy Healing

This study demonstrates that S100A11 promotes tenocyte-derived stem cell apoptosis and impairs tendon healing by interacting with UCHL3 to dysregulate the Bcl-2/Bax/Caspase-3 signaling pathway, suggesting that inhibiting S100A11 could serve as an effective therapeutic strategy for tendinopathy.

Lithium treatment drives coordinated multi-kinase remodelling of the mouse synaptic phosphoproteome

This study reveals that lithium's mood-stabilizing effects in bipolar disorder arise from a coordinated reorganization of multi-kinase phosphorylation networks in mouse synapses, rather than single-target inhibition, with these lithium-sensitive pathways showing significant enrichment in bipolar disorder genetic risk loci.

Interaction-Token Structural Alignment (ITSA): An Interpretable Framework for Protein Similarity Based on Residue-Level Chemical Interactions

The paper introduces Interaction-Token Structural Alignment (ITSA), an interpretable framework that converts protein structures into residue-level biochemical interaction tokens for local alignment, demonstrating its effectiveness in capturing family-level similarity and preserving mechanistic context where traditional geometry-focused methods fall short.

Transforming MRI volumes with Space-Filling Curves reveals Multifractal Signatures of Ageing and Dementia Progression

This study introduces Multifractal Space-filling Curve Analysis (MFSCA) to demonstrate that the spatial organization of brain structures, as measured by multifractality in MRI data, progressively deteriorates from a complex, heterogeneous state to a simpler, homogeneous one with advancing age and the progression of dementia.
