Polydopamine Nanoparticle‐Mediated Precise Near‐Infrared Optical Stimulation for Cognitive Enhancement

Advanced Science, Volume 13, Issue 56, 9 October 2026.
Polydopamine nanoparticles enable a precise, non‐genetic, and transcranial neuromodulation strategy via near‐infrared photothermal stimulation. By activating TRPV1 channels, this approach specifically enhances hippocampal gamma oscillations, thereby rescuing spatial memory deficits in models of perioperative neurocognitive disorder.

A Freeform Forward-modeling Pipeline for High-contrast Images of Circumstellar Disks Based on Automatic Differentiation

The Astronomical Journal
Modeling circumstellar disks in the traditional sense carries the assumption that the dust density distribution can be accurately described with a fixed parametric form.

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

Cytoskeleton, Volume 83, Issue 10, Page 779-794, October 2026.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Optical photometry of Sco X-2

Astronomy & Astrophysics, 1997
We present optical photometry of the galactic bulge low-mass X-ray binary GX 349+2 (Sco X-2) obtained in July 1993 and March 1996. Short-term variations up to one magnitude are present on time scales of a few hours, which are related to the known X-ray behaviour of the source.

Compound Ciwujia Granules Attenuate Stress‐Induced Anxiety‐ and Depression‐Like Behaviors via Inhibition of TNF‐α‐Associated Neuroinflammation in the dmPFC

CNS Neuroscience &Therapeutics, Volume 32, Issue 10, October 2026.
By restoring glutamatergic neuronal activity, suppressing TNF‐related inflammatory signaling pathway, and reducing microglial overactivation in the dmPFC, CWJ ameliorated stress‐induced behavioral abnormalities. ABSTRACT Aims Compound Ciwujia Granules (CWJ) have shown antidepressant‐like effects, but the neural and molecular mechanisms underlying these

Both Genetic Manipulation and Acupuncture Alleviate Depressive‐Like Behavior Mediated by Astrocytic P2X7 Receptors

MedComm, Volume 7, Issue 10, October 2026.
The efficacy of the chronic unpredictable mild stress (CUMS) model in mice was assessed using the tail suspension test (TST; A) and the forced swim test (FST; B). In both major depressive disorder (MDD) mouse models, CUMS significantly increased immobility time, indicating the development of depressive‐like behavior.

Function within disorder: Small heat shock proteins use different functional regions to chaperone tau aggregation

Protein Science, Volume 35, Issue 10, October 2026.
Abstract In numerous neurodegenerative diseases known collectively as tauopathies, the microtubule‐associated protein tau forms fibrillar aggregates that are hallmarks of disease pathology. Tauopathies represent a substantial fraction of diseases associated with protein misfolding.
