What Drives GNN Performance in Tissue Dynamics? Insights from Vertex-Model Simulations

This study benchmarks five Graph Neural Network architectures on 1,615 simulated tissue graphs undergoing T1 transitions, revealing that the Provably Powerful Graph Network (PPGN) achieves high accuracy with minimal data by employing a hybrid prediction strategy and highlighting tissue disorder as a key factor influencing model reliability.

Functional Depth Biomarkers Distinguish Lung Squamous Cell Carcinoma from Lung Adenocarcinoma

This study introduces a functional depth analysis framework integrating spatial transcriptomics and network statistics to distinguish lung squamous cell carcinoma from adenocarcinoma by identifying subtype-specific pathway coordination architectures, mutation-driven rewiring, and microenvironment programming patterns that reveal novel mechanistic biomarkers for precision oncology.

Functional inertia reveals history-dependent organization of large-scale brain dynamics

This paper introduces "functional inertia" as a history-dependent, multilevel constraint on brain dynamics that structures activity into coherent regimes and explains how the same underlying mechanism can predict better cognitive performance in healthy individuals while driving greater symptom severity in schizophrenia, thereby reframing stability and volatility as context-dependent expressions of a single organizing principle.

Effects of shoe longitudinal bending stiffness and runner level on Achilles tendon loading in experienced and novice male runners: a musculoskeletal modelling study

This musculoskeletal modelling study reveals that both runner experience level and increased shoe longitudinal bending stiffness independently elevate Achilles tendon loading, with novice runners adapting to stiffer shoes through proximal compensations while experienced runners do not, supporting an individualized approach to optimal shoe stiffness.

Identification of the type II NAD(P)H dehydrogenase gene family reveals that TaNDC1 positively regulate Fusarium head blight resistance in wheat

This study comprehensively characterizes the wheat type II NAD(P)H dehydrogenase (TaND) gene family and identifies TaNDC1 as a positive regulator of Fusarium head blight resistance that interacts with the Fhb1 locus protein TaPFT.

The rapid drop of metronidazole concentration in TYI-S-33 culture medium without Giardia trophozoites

This study reveals that metronidazole concentrations in TYI-S-33 culture medium rapidly decline due to chemical interactions with iron-cysteine clusters rather than solely due to Giardia trophozoite uptake, a phenomenon that significantly alters the interpretation of drug efficacy in experimental settings.

Clinical, cellular, and genomic consequences of a population-enriched SETD1A missense variant

This study characterizes a population-enriched SETD1A missense variant (P596L) that increases bipolar disorder risk and causes cognitive deficits by inducing SETD1A hypofunction, which disrupts chromatin regulation, triggers replication stress, and impairs neurodevelopmental timing in a manner that can be partially rescued by pharmacologic inhibition of H3K4 demethylase KDM5.
