Tailoring molecular diffusion in core-shell zeolite imidazolate framework composites realizes efficient kinetic separation of xylene isomers.

The separation of xylene isomers is a critical and energy-intensive process in the petrochemical industry, primarily due to their closely similar molecular structures and boiling points. In this work, we report the synthesis and application of a novel core-shell zeolitic imidazolate framework (ZIF) composite, ZIF-65@ZIF-67, designed to significantly enhance the kinetic separation of xylene isomers through a synergistic "shell-gated diffusion and core-facilitated transport" strategy. The external ZIF-67 shell selectively restricts the diffusion of larger isomers (MX and OX), while the internal ZIF-65 core accelerates the diffusion of PX, thereby amplifying the diffusion differences among the isomers.

Recent advances in optical heavy water sensors.

DO and HO, as two important solvents with very similar properties, play a pivotal role in nuclear industrial production, life and scientific research. Unfortunately, DO and HO are highly susceptible to contamination by each other, so effective qualitative and quantitative analyses of both are necessary. This review comprehensively discusses the progress in optical sensing for the detection of a trace amount of HO in heavy water or , mainly including five types of analytical systems: inorganic nanocrystals, carbon-based nanomaterials, lanthanide complexes, organic polymers, and organic small molecules.

Mung bean-derived carbon dots suppress ferroptosis of Schwann cells the Nrf2/HO-1/GPX4 pathway to promote peripheral nerve repair.

Schwann cells (SCs) can potentially transform into the repair-related cell phenotype after injury, which can promote nerve repair. Ferroptosis occurs in the SCs of injured tissues, causing damage to the SCs and exacerbating nerve injury. Targeting ferroptosis in SCs is a promising therapeutic strategy for effective repair; however, research on ferroptosis in the peripheral nervous system remains limited.

Near-Infrared Photothermally Assisted Nanoprobes Boost Signal Amplification for Fluorescence Imaging and Urinalysis of Tumor.

Early diagnosis of tumors allows effective treatment of primary cancers through localized therapeutic interventions. However, developing diagnostic tools for sensitive, simple, and early tumor (especially less than 2 mm in diameter) detection remains a challenge. Herein, we presented a biomarker-activatable nanoprobe that enabled a near-infrared (NIR) photothermally amplified signal for fluorescence imaging and urinalysis of tumor.

Objectives: This study aimed to investigate whether observed and genetically predicted early-onset CHD were related to subsequent dementia and WMH volume.

Gluteus medius contracture: A case report and review of the literature.

Rationale: Bilateral gluteus medius contractures in adults are rare in clinical practice, with only a few cases reported. These contractures may result from repeated intramuscular injections during childhood. Understanding the clinical manifestations, diagnostic process, treatment, and outcomes can provide insights into effective management strategies.

Development and validation of a radiomics-visual evoked potential nomogram for preoperative prediction of visual outcome after endoscopic craniopharyngioma resection.

Objective: Craniopharyngiomas are rare, benign brain tumors that are primarily treated with surgery. Although the extended endoscopic endonasal approach (EEEA) has evolved as a more reliable surgical alternative and yields better visual outcomes than traditional craniotomy, postoperative visual deterioration remains one of the most common complications, and relevant risk factors are still poorly defined. Hence, identifying risk factors and developing a predictive model for postoperative visual deterioration is indeed necessary.

Therapeutic Potential of GLP-1 Receptor Agonists in Diabetes and Cardiovascular Disease: Mechanisms and Clinical Implications.

Background: Glucagon-like peptide-1 (GLP-1) is a crucial incretin hormone secreted by intestinal endocrine L cells. Given its pivotal physiological role, researchers have developed GLP-1 receptor agonists (GLP-1 RAs) through structural modifications. These analogues display pharmacological effects similar to those of GLP-1 but with augmented stability and are regarded as an effective means of regulating blood glucose levels in clinical practice.

Buffering or not working: group counseling for depression and loneliness among boarding primary school students.

Introduction: Due to the acceleration of modern life rhythm, students with developing minds are susceptible to negative external influences, leading to a growing concern for their mental health. Boarding primary school students have limited interaction with relatives compared to their non-boarding counterparts, rendering them more prone to feelings of depression and loneliness, resulting in various negative emotions. Therefore, our study aimed to explore the effects of group counseling interventions on reducing depression and loneliness among adolescents.

Impaired Presynaptic Function Contributes Significantly to the Pathology of Glycine Receptor Autoantibodies.

Background And Objectives: Autoantibodies (aAbs) against glycine receptors (GlyRs) are mainly associated with the rare neurologic diseases stiff person syndrome (SPS) and progressive encephalomyelitis with rigidity and myoclonus (PERM). GlyR aAbs are also found in other neurologic diseases such as epilepsy. The aAbs bind to different GlyR α-subunits and, more rarely, also to the GlyR β-subunit.

Activated Graphite with Richly Oxygenated Surface from Spent Lithium-Ion Batteries for Microwave Absorption.

Designing spent graphite anodes from lithium-ion batteries (LIBs) for applications beyond regenerated batteries offers significant potential for promoting the recycling of spent LIBs. The battery-grade graphite, characterized by a highly graphitized structure, demonstrates excellent conductive loss capabilities, making it suitable for microwave absorption. During the Li-ion intercalation and deintercalation processes in battery operation, the surface layer of spent graphite (SG) becomes activated, forming oxygen-rich functional groups that enhance the polarization loss mechanism.

Experience using olverembatinib as maintenance therapy in patients with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph ALL) after allogeneic hematopoietic cell transplantation (allo-HCT) is limited. We retrospectively collected data from 26 patients with Ph ALL who received only olverembatinib as maintenance therapy after allo-HCT. Olverembatinib was administered as prophylaxis in 18 patients (69.

Molybdate uptake interplay with ROS tolerance modulates bacterial pathogenesis.

The rare metal element molybdenum functions as a cofactor in molybdoenzymes that are essential to life in almost all living things. Molybdate can be captured by the periplasmic substrate-binding protein ModA of ModABC transport system in bacteria. We demonstrate that ModA plays crucial roles in growth, multiple metabolic pathways, and ROS tolerance in .

CISD2-mediated mitochondrial dysfunction and iron redistribution contributes to ferroptosis in arsenic-induced nonalcoholic steatohepatitis.

Arsenic in the environment, such as sodium arsenic (NaAsO), is a frequently occurring hazard that has been linked to nonalcoholic steatohepatitis (NASH). Our prior research established the involvement of ferroptosis in arsenic-induced NASH, but the precise underlying mechanisms remain elusive. Here, we found that exposure to NaAsO had a suppressive effect on the expression of CDGSH iron-sulfur domain-containing protein 2 (CISD2) at the protein and gene levels, and overexpression of CISD2 inhibited NaAsO-induced ferroptosis and NASH.
