Umbilical cord-derived mesenchymal stromal cells attenuate neurogenic degeneration in infantile acute encephalopathy mice

This study demonstrates that intravenous administration of human umbilical cord-derived mesenchymal stromal cells (UC-MSCs) attenuates neurogenic degeneration and behavioral abnormalities in an infantile acute encephalopathy mouse model by suppressing neuroinflammation and modulating microglial activation.

Alpha Reactivity Dynamics Reveal Multi-System Variability Without Global Alpha Slowing in Fragile X Syndrome

This study demonstrates that Fragile X syndrome is characterized by region-specific alpha reactivity deficits and distributed network alterations without global alpha slowing, supporting a multi-system model of dysfunction where these dynamics serve as a promising translational biomarker.

TopBP1 condensates orchestrate nuclear actin assembly to ensure genome stability

This study reveals that TopBP1 condensates act as central architectural hubs that orchestrate nuclear actin assembly and nuclear envelope integrity via ATR-mTOR signaling to maintain genome stability during replication stress, a mechanism that is hijacked by chemo-resistant colorectal cancer cells to promote survival.

Effects of Landscape Change on Habitat Suitability for Iberian Large Carnivores: Current Trends and Future Scenarios

This study assesses how past and future land-use changes impact habitat suitability and connectivity for the Iberian wolf, brown bear, and Iberian lynx, revealing that while overall habitat availability has remained stable, agricultural intensification poses a severe future threat by increasing fragmentation and reducing connectivity, whereas rural abandonment offers potential improvements.

Spreading of α-synuclein rewires organelle communication and disrupts neuron-astrocyte mitochondrial quality control

This study reveals that spreading α-synuclein accumulates at tri-organelle contact sites to stabilize and rewire organelle communication, thereby impairing neuron-astrocyte mitochondrial quality control by disrupting mitochondrial transfer to astrocytes.

Normative modeling in neuroimaging across psychiatric and neurological disorders: a systematic review and the NORMA reporting checklist

This systematic review of 122 neuroimaging studies highlights the shift toward individualized normative modeling in psychiatry and neurology, identifies critical gaps in empirical foundations and reporting transparency, and introduces the 18-item NORMA checklist to standardize model construction, validation, and clinical application.
