The ongoing interplay among plants, insects, and bacteria underscores the intricate balance of defense mechanisms in ecosystems. Regurgitant bacteria directly/indirectly impact plant immune responses, but the underlying mechanism is unclear. Here, we focus on the interaction between regurgitant bacteria, diamondback moth (DBM), and plant.

Enhanced removal of sulfonamide antibiotics in water using high-performance S-nZVI/BC derived from rice straw.

Sulfonamide antibiotics (SAs) are widely used in the biomedical field but pose an environmental risk as ecotoxic pollutants. Developing eco-friendly methods to degrade SAs into harmless compounds is crucial. In this work, biochar (BC) was prepared from rice straw via pyrolysis and used to support S-nZVI, thereby forming the S-nZVI/BC composites.

Microenvironmental modulation breaks intrinsic pH limitations of nanozymes to boost their activities.

Functional nanomaterials with enzyme-mimicking activities, termed as nanozymes, have found wide applications in various fields. However, the deviation between the working and optimal pHs of nanozymes has been limiting their practical applications. Here we develop a strategy to modulate the microenvironmental pHs of metal-organic framework (MOF) nanozymes by confining polyacids or polybases (serving as Brønsted acids or bases).

Clozapine and rapamycin reverse behavioral abnormalities in an animal model of autoimmune schizophrenia.

Objective: Autoantibody-associated psychosis represents a distinct disease subgroup of patients with schizophrenia with a suspected autoimmune origin. Although preliminary studies have suggested adjunctive drug treatment strategies targeting the immune system, further validation of these findings is warranted. Autoantibodies against SFT2D2 have been identified in patients with schizophrenia.

Topotactic Transformation in FeO Induces Spontaneous Growth of Compositionally Diverse Nanostructures.

Topotactic transformation is an emerging strategy for synthesizing materials with exotic functional properties. In this report, instead of producing new crystals with related structures, we exploited the topotactic transformation phenomenon to spontaneously produce compositionally diverse nanostructures on the transforming substrate. The surface of magnetite nanoparticles (FeO NPs) is topotactically transformed into maghemite (γ-FeO).

Transcriptomic analysis of male diamondback moth antennae: Response to female semiochemicals and allyl isothiocyanate.

Female semiochemicals and allyl isothiocyanate (AITC) attract moths, and the moths use odorant-degrading enzymes (ODEs) to break down the excess odor. By identifying antennae-specific ODEs, researchers have established the molecular foundation for odorant degradation and signal inactivation in insects. This enables further exploration of new pest control methods.

Methods: A retrospective analysis of clinical data from 16585 trauma patients treated at the First Hospital of Lanzhou University Trauma Center from November 1, 2021 to October 31, 2023 was conducted.

Whether perceived limb heaviness affects return to work among patients with ischemic stroke.

This study aims to explore the relationship between perceived limb heaviness and return to work (RTW) among ischemic stroke patients. We retrospectively reviewed the data of consecutive participants recruited in the CIRCLE study. Perceived limb heaviness was gathered from self-reported by 1-year follow-up.

Absorption and transport of different ZnO nanoparticles sizes in Agrostis stolonifera: Impacts on physiological, biochemical responses, root exudation, and microbial community structure.

Nanomaterials play a crucial role in various applications, but their environmental impact necessitates effective recycling strategies. This study investigates the effects of different ZnO nanoparticles (ZnO-NPs) sizes (0, 30, 50, and 90 nm) on Agrostis stolonifera, focusing on physiological and biochemical responses, root exudate, and microbial community structure. The results showed that the most optimal physiological and biochemical responses, including enhanced plant growth and increased activities of superoxide dismutase, peroxidase, and catalase, were observed at 50 nm ZnO-NPs.

Copper depletion-induced tumor cuproptosis.

Copper homeostasis is crucial for cells, especially for rapidly proliferating cancerous cells. Copper imbalance-induced cell death (, cuproptosis) has emerged as a new strategy for tumor therapy. While copper accumulation-induced cuproptosis has been extensively investigated and its underlying mechanism recently elaborated, copper depletion-induced cuproptosis remains largely unexplored.

Global patterns of leukemia by subtype, age, and sex in 185 countries in 2022.

In 2022, leukemia ranked as the second most common hematological malignancy after non-Hodgkin lymphoma worldwide. However, updated global estimates of leukemia incidence by subtype are unavailable. We estimated leukemia incidences for different leukemia subtypes by country, world region, and human developmental index using data from the Cancer Incidence in Five Continents databases combined with the GLOBOCAN 2022 estimates of leukemia in 185 countries.

A nomogram for predicting hemorrhagic transformation in acute ischemic stroke receiving intravenous thrombolysis with extended time window.

A recent randomized controlled clinical trial expanded the time window of intravenous thrombolysis (IVT) in patients with acute ischemic stroke (AIS) beyond 4.5 hours by applying neuroimaging standards, enabling more patients to benefit from IVT. However, hemorrhagic transformation (HT) after IVT is still a major concern.

Vanishing point estimation inspired by oblique effect in a field environment.

Estimating a vanishing point (VP) is a core problem for understanding three-dimensional scenes and autonomous navigation. Existing methods are essential to estimating VPs in indoor and urban environments. However, doing so in diverse, unstructured, changing, and unexpected field environments remains a considerable challenge.

Asymmetric right ventricular myocardial work correlates with gold standard measurements of cardiac function in pulmonary hypertension.

Right ventricular (RV) (dys)function determines outcomes in pulmonary hypertension (PH). We previously found that asymmetric RV myocardial work (MW) corresponds with inefficient RV function in experimental PH models. We therefore aimed to investigate regional distribution of RV MW and its correlation with catheter hemodynamics in children with PH.

Risk stratification in the clinical application of minimal residual disease assessment in acute myeloid leukemia.

Background: In acute myeloid leukemia (AML), further investigation is warranted to integrate measurable residual disease (MRD) with genetic characteristics for formulating a dynamic prognostic system for predicting response and selecting appropriate postremission therapeutic strategies.

Methods: The authors incorporated MRD with genetic risk classification and assessed its impact on transplantation decision making within different risk cohorts, comprising 769 patients with newly diagnosed AML across three clinical trials. Only patients who achieved complete remission (CR) within two courses of chemotherapy were selected.

Helicobacter pylori outer membrane vesicles directly promote Aβ aggregation and enhance Aβ toxicity in APP/PS1 mice.

NompC regulates locomotion and touch sensation in Bactrocera dorsalis.

No mechanoreceptor potential C (NompC) is a major mechanotransduction channel with an important role in sensing of external mechanical stimuli by insects, which help these organisms to avoid injury and adapt to environmental changes. To explore the biological functions of NompC in Bactrocera dorsalis, a notorious agricultural pest, we successfully generated NompC knockout strains using clustered regularly interspaced small palindromic repeats (CRISPR) / CRISPR-associated nuclease 9 (Cas9) technology. BdorNompC knockout led to an adult lethal phenotype, with approximately 100% mortality at 3 d after eclosion.

Pan-cancer and single-cell analysis reveal dual roles of lymphocyte activation gene-3 (LAG3) in cancer immunity and prognosis.
