Soil cadmium (Cd) pollution poses a significant environmental threat, impacting global food security and human health. Recent studies have highlighted the potential of arbuscular mycorrhizal (AM) fungi to protect crops from various heavy metal stresses, including Cd toxicity. To elucidate the tolerance mechanisms of maize in response to Cd toxicity under AM symbiosis, this study used two maize genotypes with contrasting Cd tolerance: Zhengdan958 (Cd-tolerant) and Zhongke11 (Cd-sensitive).

Natural killer cell-derived exosomes (NK-exo), as an important bridge of information transmission between cells, also have a certain killing effect on tumor cells. On this basis, this study investigated the specific regulatory mechanism of NK-exo on LC cells.

This one-shot learning rule differs in five essential aspects from previously considered plasticity mechanisms. We introduce a transparent model for the core function of this learning rule and establish a theory that enables a principled understanding of the system of memory traces that it creates.

However, the mechanism associated with its symptoms such as anxiety-like behaviors is not well understood. It is aimed to investigate the underlying mechanisms of the medial septum (MS)-medial habenula (MHb) neural circuit modulating the anxiety-like behaviors of PTSD mice through in vivo fiber photometry recording, optogenetics, behavioral testing by open-field and elevated plus maze, fluorescent gold retrograde tracer technology, and viral tracer technology.

Background: Cancer patterns in China are becoming similar to those in the United States (US). Comparing the recent cancer profiles, trends, and determinants in China and the US can provide useful reference data.
Methods: This study used open-source data.
Introduction: Involved site radiation therapy (ISRT) is a widely used treatment for primary ocular adnexal mucosa-associated lymphoid tissue (MALT) lymphoma with control rates over 85%; however, its complications could reach 30%-50%. Intralesional rituximab injection has shown promising results with remission rates between 65% and 100% and minimal complications. This study aimed to conduct a multicentre randomised controlled clinical trial to compare the safety and efficacy of intralesional rituximab injection versus ISRT on primary ocular adnexal MALT lymphoma.

However, the frequent start-up and shut-down (SU/SD) caused fuel starvation operation condition seriously deteriorates the performance and lifetime of the fuel cell. In this manuscript, VO was incorporated in the anode to restrain fuel starvation of the electrode.

Cisplatin (CDDP) is the first treatment choice for ovarian cancer and it is initially effective. However, 80% of ovarian cancer patients eventually relapse and develop resistance, resulting in chemotherapy failure.

Herein, we have reported an approach to develop lysine-targeted covalent inhibitors of PI3Kδ by in situ interaction upgradation of the H-bonding to covalent bonding. Several warhead groups were introduced and screened in situ, leading to lysine-targeted covalent inhibitors bearing aromatic esters with high bioactivity and PI3Kδ selectivity.

Introduction: Acute leukemia harboring rearrangement of the Mixed lineage leukemia (MLL) and/or mutation of the nucleophosmin is a type of poorly prognostic and highly malignant leukemia which is extremely difficult to treat. Blocking the protein-protein interaction between Menin and MLL is a strategic approach for treating leukemias, as a new direction for drug discovery. Many biotech and pharmaceutical companies made great efforts to this drug development field, and a large number of small molecular Menin-MLL PPI inhibitors were reported during the recent three years.

Recurrent neural networks in the machine learning domain and bio-inspired spiking neural networks in the neuromorphic computing domain are two promising candidate models for dealing with spatiotemporal data via extrinsic dynamics and intrinsic dynamics, respectively. Nevertheless, these networks have disparate modeling paradigms, which leads to different performance results, making it hard for them to cover diverse data sources and performance requirements in practice.

Here, we report that the host is a critical modulator to regulate the lifestyle switch and pathogenicity heterogeneity of the opportunistic pathogens utilizing the and bacterium model system. First, we find that larvae efficiently outcompete and typically drive a bacterial switch from pathogenicity to commensalism toward the fly.

However, it is often difficult to explore the generation mechanism and achieve polymorphic control in artificial supramolecular assembly systems. In this work, we propose a feasible thought for exploring the transformation mechanism of polymorphism in peptide assembly from the perspective of thermodynamic regulation, which enables polymorphic composition to be limited by switchable intramolecular CH⋯π attraction within a certain temperature range.
