Astrocytic PERK Deficiency Drives Prefrontal Circuit Dysfunction and Depressive‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
Chen et al. show that the endoplasmic reticulum (ER) stress sensor PERK is downregulated in prefrontal cortex (PFC) astrocytes in major depressive disorder and in chronic‐stress mouse models. In young mice, astrocyte‐specific PERK loss reduces the synaptogenic cue thrombospondin‐1 (TSP1), leading to synaptic and circuit deficits and depressive‐like ...

TNEA Regulates Hippocampal Oscillation by Improving Inhibitory Synaptic Plasticity to Ameliorates Cognitive Impairment in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
TNEA improves cognition in 5xFAD mice by modulating parvalbumin‐positive interneurons in hippocampal CA1. TNEA enhances gamma oscillations during rest and theta power during novel object recognition, restoring excitation/inhibition balance. These findings support TNEA as a minimally invasive therapy for Alzheimer's disease.

Irreversible transformation of ferromagnetic ordered stripe domains in single-shot IR pump - resonant X-ray scattering probe experiments

open access: yes, 2015
The evolution of a magnetic domain structure upon excitation by an intense, femtosecond Infra-Red (IR) laser pulse has been investigated using single-shot based time-resolved resonant X-ray scattering at the X-ray Free Electron laser LCLS. A well-ordered

Nasal Mucosa‐Derived Extracellular Vesicles as a Systemic Antiaging Intervention

open access: yesAdvanced Science, EarlyView.
This study shows that nasal mucosa‐derived extracellular vesicles (nmEVs) exert systemic anti‐ageing effects in mice by restoring circadian rhythm, suppressing cellular senescence, and improving cognitive function. In aged human bone marrow mesenchymal stem cells, nmEVs reverse senescence‐associated phenotypes and reactivate core clock gene expression.

Lesarten des Labyrinths / Schemata des Lesens [PDF]

open access: yes, 2009
Die Erzählung vom Labyrinth präsentierte sich als eine lineare Verfallsgeschichte vom 'ursprünglich und eigentlich' einwegigen Labyrinth zum Irrgarten, wie sie Eco noch mit seiner dreistufigen Fortschrittsgeschichte bestätigt und fortschreibt.

Enhanced Selenium Supplement Extends Lifespan and Delays Multi‐Organs Aging by Regulating the Sik1 Pathway Through Maintaining Calcium Homeostasis

open access: yesAdvanced Science, EarlyView.
Aging involves physiological decline and heightened disease susceptibility, necessitating effective interventions. Redox‐responsive selenium‐loaded nanoparticles (SeMSNs) are developed, which delay cellular senescence by reducing oxidative stress and senescence markers (p16/p21). In aged mice, SeMSNs extend lifespan, improve organ function, and restore

Microglial Feimin Alleviates Cognitive Impairment in High‐Fat Diet‐Fed Mice

open access: yesAdvanced Science, EarlyView.
Microglial feimin deletion exacerbates lipotoxicity‐induced neuroinflammation and cognitive decline. In both in vitro and in vivo models, loss of feimin aggravated lipid droplet accumulation, IL‐1β/IL‐6 release, and neuronal injury through the PI3K–AKT–mTOR pathway, ultimately leading to severe neuronal apoptosis and cognitive impairment under high‐fat
