The iridium oxide (IrO) catalyst for the oxygen evolution reaction used industrially (in proton exchange membrane water electrolyzers) is scarce and costly. Although ruthenium oxide (RuO) is a promising alternative, its poor stability has hindered practical application. We used well-defined extended surface models to identify that RuO undergoes structure-dependent corrosion that causes Ru dissolution.

In situ synchrotron x-ray scattering performed during growth of the parent phase, NdNiO, shows that the necessary layer-by-layer deposition sequence does not follow the sequence of the formula unit but an alternate order due to the relative stability of the perovskite unit cell. We exploit this insight to grow ultrathin NdNiO heterostructures and conduct in situ studies of topotactic reduction, finding that formation of the square-planar phase occurs rapidly and is highly sensitive to reduction temperature, with small deviations from the optimum condition leading to inhomogeneity and the loss of superconductivity.

Here we report the upcycling of polyethylene terephthalate (PET) plastic and CO2 toward valuable potassium diformate, terephthalic acid, and H2 fuel via decoupled electrolysis. This product-oriented process is realized by two electrolyzers: (1) a solid-state-electrolyte based CO2 electrolyzer and (2) a solid-polymer-electrolyte-based PET electrolyzer.

Estimation of ancestral admixture is essential for creating personal genealogies, studying human history, and conducting genome-wide association studies (GWAS). The following three primary methods exist for estimating admixture coefficients. The frequentist approach directly maximizes the binomial loglikelihood.

Originally introduced in the Bayesian imaging literature, ProxMCMC employs the Moreau-Yosida envelope for a smooth approximation of the total-variation regularization term, fixes variance and regularization strength parameters as constants, and uses the Langevin algorithm for the posterior sampling. We extend ProxMCMC to be fully Bayesian by providing data-adaptive estimation of all parameters including the regularization strength parameter.

Nuclear factor erythroid-derived 2-related factor 2 (NRF2), a pivotal regulator of redox homeostasis, orchestrates antioxidant response that effectively counters oxidative stress and inflammatory response in a variety of acute pathophysiological conditions, including acute kidney injury (AKI) and early stage of renal toxicity. However, if persistently activated, NRF2-induced transcriptional cascade may disrupt normal cell signaling and contribute to numerous chronic pathogenic processes such as fibrosis.

This study was aiming to identify markers associated with ferroptosis/cuproptosis in AAA by bioinformatics analysis combined with machine learning models and to perform experimental validation.
Methods: This study used three scRNA-seq datasets from different mouse models and a human PBMC bulk RNA-seq dataset.
Rheumatoid arthritis (RA) is a prevalent autoimmune disease characterized by chronic inflammation and excessive proliferation of the synovium. Currently, treatment options focus on either reducing inflammation or inhibiting synovial hyperplasia. However, these modalities are unsatisfactory in achieving the desired therapeutic outcomes.

However, some patients cannot achieve complete or partial remission at 6 months. This study aimed to evaluate the efficacy of traditional immunotherapy combined with hydroxychloroquine (HCQ), a well-known immune regulator, in patients with PMN.

This study aimed to explore the relationship between mutations and immune checkpoint molecules (ICMs) in patients with acute myeloid leukemia (AML).
Methods: The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) databases were used to identify the ICMs associated with mutations.
Purpose: This study aimed to identify major lesion characteristics of chronic total occlusions (CTOs) that predict failed percutaneous coronary intervention (PCI) using pre-procedure coronary computed tomography angiography (CCTA) in combination with conventional coronary angiography (CCA).
Methods: Consecutive patients with at least one CTO of the native coronary arteries received CCTA and CCA-guided PCI, with computed tomography performed before or during PCI.
Results: A total of 76 patients with CTO were included in this study.
Objective: To evaluate the efficacy and safety of prophylactic nebulized antibiotics in preventing intensive care unit (ICU)-acquired pneumonia through a meta-analysis.
Methods: Randomized controlled trials (RCTs) investigating the potential reduction in the incidence of ICU-acquired pneumonia through prophylactic nebulized antibiotics were collected by searching the PubMed, Embase, and Cochrane Library databases from their inception to January 23, 2024. The primary endpoint was the incidence of ICU-acquired pneumonia, while the secondary endpoints included mortality, length of ICU stay, mechanical ventilation days, and nebulization-related side effects.
Objective: To evaluate the clinical efficacy of early tracheotomy in neurologic critical care patients.
Methods: A retrospective analysis was conducted on 100 patients with severe craniocerebral injury (SCI) who underwent percutaneous tracheotomy at The First Affiliated Hospital, Zhejiang University School of Medicine from January 2021 to February 2022. Of them, 52 cases (observation group) received the procedure within 24 hours of injury, while 48 patients (control group) received the procedure after 24 hours.
Dual leucine zipper kinase (DLK), expressed primarily in neuronal cells, is a regulator of neuronal degeneration in response to cellular stress from chronic disease or neuronal injury. This makes it an attractive target for the treatment of neurodegenerative diseases such as Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis, and neuronal injury, such as chemotherapy-induced peripheral neuropathy. Here, we describe the discovery of a potent, selective, brain-penetrant DLK inhibitor, KAI-11101 ().

Microglia play a dual role in neuroinflammatory disorders that affect millions of people worldwide. These specialized cells are responsible for the critical clearance of debris and toxic proteins through endocytosis. However, activated microglia can secrete pro-inflammatory mediators, potentially exacerbating neuroinflammation and harming adjacent neurons.

The water-liftoff fabrication of freestanding oxide membranes at nanometer-scale thickness marks a major breakthrough in expanding the family of soft electromagnetic materials. The structure reconstruction in the newly formed two-dimensional freestanding membrane due to the chemical liftoff provides an excellent opportunity to achieve applicable functionalities. In this report, we present the anisotropic relaxation of a LaMnO epitaxial film into a nearly wrinkle- and crack-free membrane, realized by high-temperature (160 °C)-treated PMMA as the protective layer during the water liftoff process.

Methods: This retrospective study hypothesizes that, unlike in cases of trauma and degenerative disorders where delayed decompression surgery often leads to poor outcomes, delayed decompression surgery for MESCC-induced paralysis yields relatively favorable results. This study included MESCC patients who had been paralyzed for more than 48 h and underwent decompressive surgery between January 2012 and December 2020.
Cervical cancer, often driven by high-risk human papillomavirus (HPV) infections such as HPV16 or HPV18, remains a leading cause of cancer-related deaths. HPV16, found in about 90% of cervical cancer patients, harbors key oncogenic related genes (E6, E7, E2, E5) and an upstream regulatory region (URR) that contribute to cancer progression. This study introduces a novel approach using a recombinant oncolytic herpes simplex virus type 1 (HSV-1) named SONC103, armed with a CRISPR/Cas9 gene editing system.

In the present study, we aimed to mechanistically explore the role of PINK1 in pilocarpine-induced status epilepticus (SE) in Sprague-Dawley rats. Evidence from immunohistochemistry, western blotting, biochemical assays, and behavioral testing showed that pilocarpine-induced SE led to increased levels of PINK1 phosphorylation, mitophagy, mitochondrial oxidative stress, neuronal damage and learning and memory deficits.
