Fixed-panel tissue RNA prioritization in extraskeletal myxoid chondrosarcoma: CSPG4 evidence across cohorts with comparator and sequencing-year limits

This study evaluates a fixed 11-gene RNA panel in extraskeletal myxoid chondrosarcoma and identifies CSPG4 as a prioritized candidate with strong but year-sensitive and comparator-dependent expression, while ultimately concluding that current evidence precludes a broadly robust claim for its therapeutic selectivity due to unresolved issues regarding normal-tissue overlap and malignant-cell localization.

Motor performance, reward-based Y-maze behaviour and regional brain histological abnormalities in a Goldblatt renovascular hypertension rat model: an exploratory controlled study

This exploratory controlled study demonstrates that Goldblatt renovascular hypertension in rats is associated with significant motor deficits, delayed reward-based spatial navigation, and regional brain histological abnormalities, though the lack of animal-level correlations and hippocampal tissue limits definitive causal inferences.

A Darwinian Atomic-Process Paradigm for Complex-System Simulation: Local Trial, Conditional Gating, and Validation Against LTEE Data

This paper proposes a Darwinian atomic-process simulation paradigm inspired by tabletop role-playing games, which decomposes complex systems into stochastic local steps with conditional propagation gates, demonstrating through validation against Lenski Long-Term Evolution Experiment data that this approach significantly improves the accuracy of long-horizon adaptive dynamics modeling compared to standard models.

Quantitative dissection of the metastatic cascade at single colony resolution

This study introduces MOBA-seq, a high-throughput in vivo platform that quantitatively maps the genetic and microenvironmental determinants of the metastatic cascade at single-colony resolution, revealing metastatic seeding as the primary bottleneck and identifying key regulators like CREBBP in small cell lung cancer.

From Crop Raiding to Cultural Symbol: Reconciling Golden Langur (Trachypithecus geei) Conservation with Rural Livelihood in the Eastern Himalaya

This study demonstrates that the critically endangered Golden Langur persists in the human-dominated agricultural landscapes of the Eastern Himalaya through flexible habitat use and the maintenance of positive local attitudes driven by cultural values, suggesting that conservation success in fragmented habitats relies more on mitigating human-wildlife conflict than on expanding wilderness areas.

A Developmental Stability Theory of Predictive Hierarchies: Why Some Perceptual Architectures Remain Stable Under Perturbation

This paper proposes a Developmental Stability Theory that explains the late-adolescent onset of schizophrenia as a loss of stability in perceptual hierarchies, governed by a mathematical criterion linking effective dimensionality, neural coupling, and neuromodulatory gain to multiscale mechanisms ranging from NMDA receptor dysfunction to sensory experience.
