An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

open access: yesAdvanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

open access: yesAdvanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

Distinct origins of human low and high alpha rhythms revealed by simultaneous EEG-SEEG

open access: yesCommunications Biology
Alpha-band activity is the most prominent neurobiological feature of scalp electroencephalography (EEG) signals, recent findings showed that there is more than one alpha rhythm coexisted in this 8-13 Hz band, but the generation mechanism of them was not ...

On the Physiological Modulation and Potential Mechanisms Underlying Parieto-Occipital Alpha Oscillations

open access: yesFrontiers in Computational Neuroscience, 2018
The parieto-occipital alpha (8–13 Hz) rhythm is by far the strongest spectral fingerprint in the human brain. Almost 90 years later, its physiological origin is still far from clear.

Alpha and Theta Rhythms as Markers of Cognitive Effort

open access: yesРоссийский психологический журнал, 2022
Introduction. This review article combines the theory of motivational intensity and the theory of mental effort with studies of oscillatory correlates of the performance of complex cognitive tasks. The phenomenon of effort has been a longstanding subject

Alpha, beta: The rhythm of the attentional blink [PDF]

open access: yesPsychonomic Bulletin & Review, 2017
Extant theories of the attentional blink propose that the most critical factor in determining second target accuracy is the time that elapses between the first and second targets. We report that this conclusion has overlooked an equally important determinant, namely, the frequency of the entraining stream in which these targets are embedded ...

Paul Valéry and the search for poetic rhythm [PDF]

open access: yes, 2010
Throughout his theoretical writings, Valéry insists on two fundamental principles: poetic rhythm is undefinable and yet it is central to poetry. Although his verse practice evolves from irregularity to regularity, Valéry insists that predictable metrical

Zwitterionic Polymer Coating Enabled Chronic Dopamine Sensing and Electrophysiology Recording in Free‐Moving Mice

open access: yesAdvanced Healthcare Materials, EarlyView.
Application of a zwitterionic poly(sulfobetaine methacrylate) (PSB) coating to microelectrode arrays and Ag/AgCl reference electrodes effectively inhibits biofouling and structural degradation. This strategy successfully enables simultaneous, long‐term electrophysiological recording and dopamine sensing in freely behaving mice, facilitating ...
