Table_2_Identification of Potential Key circRNAs in Aged Mice With Postoperative Delirium.XLS
Postoperative delirium (POD) is a common postoperative complication in elderly patients and seriously affects postoperative recovery. The exact mechanism of POD is still unclear. Therefore, it is necessary to explore the mechanism of POD in transcriptional regulation. At present, circRNAs have been proven to play an important role in a variety of mental health and cognitive disorders, such as Alzheimerâs disease, depression and schizophrenia. To reveal the effect of circRNA on POD, we used microarray to analyze the differential expression profiles of circRNAs in the hippocampus of 12-month-old mice between the tibial fracture and control groups. A total of 1,4236 circRNAs were identified. Compared with the control group, there were 500 circRNAs with increased expression and 187 with decreased expression. The accuracy of the microarray data was further verified by qRTâPCR. Finally, GO enrichment and KEGG pathway analyses indicated that changes in axon orientation, ubiquitin-mediated proteolysis, glutamate synapses, the estrogen signaling pathway, the RAS signaling pathway and other systems may be important potential pathological mechanisms in the progression of POD. In particular, we found that the HOMER1 gene and its transcript mmu_circRNA_26701 are specifically expressed in the glutamate synapse, which may provide new clues and intervention targets for the progression of this refractory disease.</p

A Hydrogel Electrolyte toward a Flexible Zinc-Ion Battery and Multifunctional Health Monitoring Electronics
The compact design of an environmentally adaptive battery
and effectors
forms the foundation for wearable electronics capable of time-resolved,
long-term signal monitoring. Herein, we present a one-body strategy
that utilizes a hydrogel as the ionic conductive medium for both flexible
aqueous zinc-ion batteries and wearable strain sensors. The poly(vinyl
alcohol) hydrogel network incorporates nano-SiO2 and cellulose
nanofibers (referred to as PSC) in an ethylene glycol/water mixed
solvent, balancing the mechanical properties (tensile strength of
6 MPa) and ionic diffusivity at â20 °C (2 orders of magnitude
higher than 2 M ZnCl2 electrolyte). Meanwhile, cathode
lattice breathing during the solvated Zn2+ intercalation
and dendritic Zn protrusion at the anode interface are mitigated.
Besides the robust cyclability of the Znâ„PSCâ„V2O5 prototype within a wide temperature range (from â20
to 80 °C), this microdevice seamlessly integrates a zinc-ion
battery with a strain sensor, enabling precise monitoring of the muscle
response during dynamic body movement. By employing transmission-mode operando XRD, the self-powered sensor accurately documents
the real-time phasic evolution of the layered cathode and synchronized
strain change induced by Zn deposition, which presents a feasible
solution of health monitoring by the miniaturized electronics

Enhancing Temperature Adaptability of Aqueous Zinc Batteries via Antifreezing Electrolyte and Site-Selective ZnSe-Ag Interface Layer Design
Rechargeable
aqueous zinc batteries (RAZBs) represent a sustainable,
environmentally benign, cost-efficient energy storage solution for
the scaled renewable power system. However, the cycling endurance
and temperature adaptability of RAZBs are hindered by practical technological
barriers such as the subzero freezing point of aqueous electrolyte,
severe cation dissolution of the cathode, and dendrite growth on the
Zn anode. Herein, we optimize the hybrid electrolyte formulation of
8 M ZnCl2 in the ethylene glycol-water mixed solvent to
reconfigure the hydrogen bonding and [Zn(H2O)1.80(EG)0.23]2+ solvation sheath, which well balances
the ionic conductivity and the antifreezing property until â125
°C. As monitored by operando X-ray diffraction,
meanwhile, the structural dissolution of the V2O5 cathode upon the dynamic cycling and static idling storage at elevated
temperature are effectively restrained. At the anode side, the thermally
induced substitution between the Ag2Se overcoating and
Zn foil in situ constructs the site-selective, mosaic
interface layer, in which the solvophilic ZnSe facilitates the desolvation,
while the Ag species provide zincophilic nucleation sites for high-throughput
Zn deposition. The synergistic coupling of the antifreezing electrolyte
and anode interfacial design enables the wide-temperature-range adaptability
of the RAZB prototype (10 ÎŒm Zn foil and 1 mAh cmâ2 V2O5 cathode), which balances the cycling
endurance (92.5% capacity retention rate for 1000 cycles), 84.7% mitigation
of the self-discharge rate at 55 °C, as well as the secured cyclability
even at â40 °C
Boosting Li-Ion Diffusion Kinetics of Na<sub>2</sub>Ti<sub>6â<i>x</i></sub>Mo<sub><i>x</i></sub>O<sub>13</sub> via Coherent Dimensional Engineering and Lattice Tailoring: An Alternative High-Rate Anode
Featured with an exposed active facet,
favorable ion diffusion
pathway, and tailorable interfacial properties, low-dimensional structures
are extensively explored as alternative electroactive materials with
game-changing redox properties. Through a stepwise âproton
exchange-insertion-exfoliationâ procedure, in this article,
we develop Na2Ti6âxMoxO13 (NTMO) nanosheets with weakened
out-of-plane bonding and in-plane Mo6+ doping of the tunnel
structure. Real-time phase tracking of the laminated NTMO structures
upon the lithiation/delithiation process suggests mitigated lattice
variation; meanwhile, the kinetics simulation shows a mitigated Li-ion
diffusion barrier along the [010] orientation. At an industrial-level
areal capacity loading (2.5 mAh cmâ2), the NTMO
electrode maintains robust cycling endurance (91% capacity retention
for 2000 cycles) even at 40 C, as well as the high energy/power densities
in the as-constructed NTMO||LiFePO4 full cell prototype.
The dimensional and lattice modifications presented in this study
thus encourage further exploration of the tailored cation diffusion
pathway for the construction of fast-charging batteries
Unleashing the Potential of High-Capacity Anodes through an Interfacial Prelithiation Strategy
The scalable development of an environmentally adaptive
and homogeneous
Li+ supplementary route remains a formidable challenge
for the existing prelithiation technologies, restricting the full
potential of high-capacity anodes. In this study, we present a moisture-tolerant
interfacial prelithiation approach through casting a hydrophobic poly(vinylidene-co-hexafluoropropylene) membrane blended with a deep-lithiated
alloy (Li22Si5@C/PVDF-HFP)
onto Si based anodes. This strategy could not only extend to various
high-capacity anode systems (SiOx@C, hard
carbon) but also align with industrial roll-to-roll assembly processes.
By carefully adjusting the thickness of the prelithiation layer, the
densely packed Si@C electrode (4.5 mAh cmâ2) exhibits
significantly improved initial Coulombic efficiency until a close-to-unit
value, as well as extreme moisture tolerance (60% relative humidity).
Furthermore, it achieves more than 10-fold enhancement of ionic conductivity
across the electrode. As pairing the prelithiated Si@C anode with
the LiNi0.8Co0.1Mn0.1O2 cathode, the 2 Ah pouch-format prototype balances an energy density
of âŒ371 Wh kgâ1 and an extreme power output
of 2450 W kgâ1 as well as 83.8% capacity retention
for 1000 cycles. The combined operando phase tracking and spatial
arrangement analysis of the intermediate alloy elucidate that the
enhanced Li utilization derives from the gradient stress dissipation
model upon a spontaneous Li+ redistribution process
