Detoxifying reactive oxygen species (ROS) that accumulate under saline conditions is crucial for plant salt tolerance. The Salt Overly Sensitive (SOS) pathway functions upstream, while flavonoids act downstream, in ROS scavenging under salt stress. However, the potential crosstalk between the SOS pathway and flavonoids in regulating salt stress responses and the associated mechanisms remain largely unexplored.

A universal strategy that bridges small-area devices and large-area modules is imperative for advancing PSC technology from the lab toward market readiness. Here, to effectively address the Pb-based defect proliferation issues of perovskite surfaces, an ,-maleoyl-glycine (NMG) post-treatment anchoring strategy was proposed.

The Ni and GdCe targets are first cosputtered to form films with a stack-layered structure of metallic Ni and GDC, followed by sputtering YZr and GdCe targets alternatively to make multilayer electrolytes. By annealing the sputtered anode-electrolyte assembly with the LaSrCoFeO cathode in a single step at 1000 °C, full cells feature heterostructure ceramic multilayers; NiO-GDC nanocomposites with heterointerfaces are constructed, while the multilayer electrolytes are fully dense.

While the neural mechanisms underlying CSM remain poorly understood, changes in brain network connectivity, particularly within the context of static and dynamic functional network connectivity (sFNC and dFNC), may provide valuable insights into disease pathophysiology. This study investigates brain-wide connectivity alterations in CSM patients using both sFNC and dFNC, combined with machine learning approaches, to explore their potential as biomarkers for disease classification and progression.

In this article, we explore the risk factors of ARF and propose a prognostic model of ARF for PCP patients.
Methods: In this multi-center, retrospective study in 6 secondary or tertiary academic hospitals in China, 120 PCP patients were screened from the Dryad database for the development of a predictive model.
Nickel-based electrocatalysts are promising for industrial water electrolysis, but the dense hydroxyl oxide layer formed during the oxygen evolution reaction (OER) limits active sites accessibility and presents challenges in balancing structural stability with effective charge transfer. Based on this, an efficient in situ leaching strategy is proposed to construct grain boundary-rich catalyst structure with high charge transfer ability and a deep catalytic active layer reached >200-nm. Under OER conditions, stable sub-nano NiAl particles are embedded in Ni(Fe)OOH, originating from leaching out the unstable NiAl phase of the initial NiAl/NiAl alloy doped with Fe.

Objective: To investigate whether activation of mitochondrial acetal dehydrogenase 2 (ALDH2) alleviates hypoxic pulmonary hypertension by regulating the SIRT1/PGC-1α signaling pathway.
Methods: Thirty 8-week-old C57 BL/6 mice were randomized into control, hypoxia, and hypoxia +Alda-1 (an ALDH2 activator) group (=10), and the mice in the latter two groups, along with 10 ALDH2 knockout (ALDH2) mice, were exposed to hypoxia (10% O, 90% N) with or without daily intraperitoneal injection of Alda-1 for 4 weeks. The changes in right ventricular function and pressure (RVSP) of the mice were evaluated by echocardiography and right ventricular catheter test, and pulmonary artery pressure was estimated based on RVSP.
To develop an energy-efficient system for the removal of chlorinated organic pollutants, Fe-Ni/reduced graphite oxide/polymerized polypyrrole@nickel foam was constructed as a catalytic cathode for pulsed electrocatalytic degradation, where cathode-catalyzed production of hydrogen radicals (H*) and hydroxyl radical (·OH) generated at the anode led to dechlorination of 4-chlorophenol (4-CP), and dechlorination products were mineralized and degraded under the action of·OH. When energy was continuously supplied to the reaction system in the constant potential mode, the 4-CP concentration near the electrode was insufficient, limiting the reaction rate. Conversely, in the square-wave pulsed potential mode, mass transfer limitations were mitigated, significantly enhancing reaction efficiency and reducing energy consumption.

Nickel oxide (NiOx) films prepared by magnetron sputtering technology exhibit excellent scalability and reproducibility, which could well meet the requirements of the large-scale production of inverted PSCs. However, NiOx prepared by vacuum methods generally has fewer surface hydroxyl groups, deteriorating the wettability and damaging the interface contact with the perovskite.
