Ultrafast Preparation of High-Entropy NASICON Cathode Enables Stabilized Multielectron Redox and Wide-Temperature (-50-60 °C) Workability in Sodium-Ion Batteries.

Avoiding severe structural distortion, irreversible phase transition, and realizing the stabilized multielectron redox are vital for promoting the development of high-performance NASICON-type cathode materials for sodium-ion batteries (SIBs). Herein, a high-entropy NaVFeTiMnCr(PO) (HE-NaTMP) cathode material is prepared by ultrafast high-temperature shock, which inhibits the possibility of phase separation and achieves reversible and stable multielectron transfer of 2.4/2.

Unloading damage evolution and rockburst risk assessment of Xuefengshan No.1 tunnel by combining multiple approaches.

Large-scale rock burst disasters often occur in high-stress and deep-buried tunnels, due to challenges in accurate forecasting and the lack of clarity regarding the underlying mechanisms largely.

Correlation of Phase Structure, Defect Relaxation, and Microwave Dielectric Properties in Low-Loss MgTiO Ceramic Systems.

Low-loss microwave dielectrics are of significant importance for the miniaturization and integration of microwave devices. In this paper, the ceramics of nominal composition MgTiO ( = 3-6) are synthesized, and the correlations among their phase compositions, defect behaviors, and microwave dielectric properties are systematically investigated. The analyses indicate that the MgTiO ceramics are a biphasic system consisting of hexagonal ilmenite-structured MgTiO and cubic spinel-structured MgTiO.

Niche Partitioning and Intraspecific Variation of Thaumarchaeota in Deep Ocean Sediments.

Deep-sea sediments contain a large number of Thaumarchaeota that are phylogenetically distinct from their pelagic counterparts. However, their ecology and evolutionary adaptations are not well understood. Metagenomic analyses were conducted on samples from various depths of a 750-cm sediment core collected from the Mariana Trench Challenger Deep.

Attempts to Create Transgenic Mice Carrying the Q3924E Mutation in RyR2 Ca Binding Site.

Over 200 point mutations in the ryanodine receptor (RyR2) of the cardiac sarcoplasmic reticulum (SR) are known to be associated with cardiac arrhythmia. We have already reported on the calcium signaling phenotype of a point mutation in RyR2 Ca binding site Q3925E expressed in human stem-cell-derived cardiomyocytes (hiPSC-CMs) that was found to be lethal in a 9-year-old girl. CRISPR/Cas9-gene-edited mutant cardiomyocytes carrying the RyR2-Q3925E mutation exhibited a loss of calcium-induced calcium release (CICR) and caffeine-triggered calcium release but continued to beat arrhythmically without generating significant SR Ca release, consistent with a remodeling of the calcium signaling pathway.

Refining Stereotaxic Deep Brain Stimulation Surgery Procedures for Parkinson Disease in Pursuit of Zero Pneumocephalus: 2-Dimensional Operative Video.

Background And Objectives: Deep brain stimulation (DBS) is a well-established intervention for alleviating both motor and nonmotor symptoms of Parkinson disease. However, a common complication of stereotaxic DBS surgery is pneumocephalus, which can compromise electrode accuracy, complicate postoperative assessments, and negatively affect the long-term outcomes of DBS surgery. This report proposes a comprehensive and robust set of recommendations aimed at optimizing DBS surgical protocols to achieve zero pneumocephalus outcomes.

In Situ Cascade Catalytic Polymerization of Dopamine Based on Pt NPs/CoSAs@NC Nanoenzyme for Constructing Highly Sensitive Photocurrent-Polarity-Switching PEC Biosensing Platform.

Nanozymes open up new avenues for amplifying signals in photoelectrochemical (PEC) biosensing, which are yet limited by the generated small-molecule signal reporters. Herein, a multifunctional nanoenzyme of Pt NPs/CoSAs@NC consisting of Co single atoms on N-doped porous carbon decorated with Pt nanoparticles is successfully synthesized for cascade catalytic polymerization of dopamine for constructing a highly sensitive photocurrent-polarity-switching PEC biosensing platform. Taking protein tyrosine phosphatase 1B (PTP1B) as a target model, Pt NPs/CoSAs@NC nanoenzymes are linked to magnetic microspheres via phosphorylated peptides.

Rnd3 protects against doxorubicin-induced cardiotoxicity through inhibition of PANoptosis in a Rock1/Drp1/mitochondrial fission-dependent manner.

Doxorubicin, a representative drug of the anthracycline class, is widely used in cancer treatment. However, Doxorubicin-induced cardiotoxicity (DIC) presents a significant challenge in its clinical application. Mitochondrial dysfunction plays a central role in DIC, primarily through disrupting mitochondrial dynamics.

Salivary features of periodontitis and gingivitis in type 2 diabetes mellitus.

Type 2 diabetes mellitus (T2DM) is associated with cellular abnormalities, tissue and organ dysfunctions, and periodontitis. This investigation examined the relationship between the oral microbiome and salivary biomarkers in T2DM patients with or without periodontitis. This cohort (35-80 years) included systemically healthy non-periodontitis (NP; n = 31), T2DM without periodontitis (DWoP; n = 32) and T2DM with periodontitis (DWP; n = 29).

Spatial distribution of bacteria in response to phytoplankton community and multiple environmental factors in surface waters in Sanggou Bay.

Coastal bays link terrestrial and oceanic carbon reservoirs and play important roles in marine carbon cycles. Particulate organic carbon (POC) produced by phytoplankton is a major autochthonous carbon source in coastal bays. Previous studies on the fate of POC produced by phytoplankton mainly focused on the relationship between phytoplankton and zooplankton in classic food webs, while our knowledge on the roles of bacterioplankton is still limited, particularly in bays under highly intensive aquaculture activities.

[Retracted] Limb remote ischemic post‑conditioning reduces injury and improves long‑term behavioral recovery in rats following subarachnoid hemorrhage: Possible involvement of the autophagic process.

Following the publication of the above paper, a concerned reader drew to the attention of the Editorial Office that the 'Sham' brain image featured in Fig. 1B on p. 23 was strikingly similar to an image that was published subsequently in the journal , whereas the control TUNEL assay data shown in Fig.

Regulation of SR and mitochondrial Ca signaling by L-type Ca channels and Na/Ca exchanger in hiPSC-CMs.

Rationale & Methods: While signaling of cardiac SR by surface membrane proteins (I & I) is well studied, the regulation of mitochondrial Ca by plasmalemmal proteins remains less explored. Here we have examined the signaling of mitochondria and SR by surface-membrane calcium-transporting proteins, using genetically engineered targeted fluorescent probes, mito-GCamP6 and R-CEPIA1er.

Results: In voltage-clamped and TIRF-imaged cardiomyocytes, low Na induced SR Ca release was suppressed by short pre-exposures to ∼100 nM FCCP, suggesting mitochondrial Ca contribution to low Na triggered SR Carelease.

Time-decay patterns and irregular disturbance: contrasting roles of abundant and rare microbial communities in dynamic coastal seawater.

Unlabelled: Microbial communities in coastal seas experience strong environmental disturbances, yet their response patterns, especially regarding differently abundant subcommunities, remain poorly understood. Here, through 16S rRNA gene amplicon sequencing, we investigated the diversity, time-decay pattern, and assembly process of abundant, conditionally rare taxa (CRT) and rare microbial subcommunities in temperate coastal waters over 60 consecutive weeks. The abundant (50.

Current progress in deciphering the molecular mechanisms underlying plant salt tolerance.

Enhancing crop salt tolerance through genetics and genomics is important for food security. It is environmentally friendly and cost-effective in maintaining crop production in farmlands affected by soil salinization and can also facilitate the utilization of marginal saline land. Despite the limited success achieved so far, it is becoming possible to bridge the gap between fundamental research and crop breeding owing to a deeper understanding of plant salt tolerance at both physiological and molecular levels.

Myricetin Alleviates Silica-Mediated Lung Fibrosis via PPARγ-PGC-1α Loop and Suppressing Mitochondrial Senescence in Epithelial Cells.

Objective: Long-term inhalation of silica dust particles leads to lung tissue fibrosis, resulting in impaired gas exchange and increased mortality. Silica inhalation triggers the aging of epithelial cells (AECs), which is a key contributor to the development of pulmonary fibrosis.
