La Doped Nickel-Manganese Oxide as High-Capacity Cathode for Sodium-Ion Batteries Guided by Bayesian Optimization.

In sodium-ion batteries, the layered transition metal oxides used as cathode often experience interlayer sliding of interlayer spacing and lattice variations during charge/discharge, leading to structural damage and capacity degradation. To address this challenge, a La doping strategy guided by Bayesian optimization has been employed to prepare the high-performance O3-NaNiMnCuLaO (NMCL) cathode material. Density functional theory calculations reveal that the O 2p orbital overlaps with the t orbital of transition metals in NMCL, facilitating the formation of Na-O-La bonds and promoting the oxygen redox reaction kinetics.

The natural immune molecules urinary Tamm-Horsfall protein and pentraxin 3 as predictors for recurrent urinary tract infection severity: a single-center self-control study.

Objective: The innate immune defense plays a pivotal role in protecting the urinary tract from uropathogenic invasion and maintaining immune homeostasis. Dysregulation of the innate immune system can result in recurrent urinary tract infections (RUTI) due to heightened susceptibility to uropathogens. Despite this, predicting the risk of recurrence and the degree of immune compromise in patients who have had one urinary tract infection remains challenging.

Microglia depletion reduces neurodegeneration and remodels extracellular matrix in a mouse Parkinson's disease model triggered by α-synuclein overexpression.

Chronic neuroinflammation with sustained microglial activation occurs in Parkinson's disease (PD), yet the mechanisms and exact contribution of these cells to the neurodegeneration remains poorly understood. In this study, we induced progressive dopaminergic neuron loss in mice via rAAV-hSYN injection to cause the neuronal expression of α-synuclein, which produced neuroinflammation and behavioral alterations. We administered PLX5622, a colony-stimulating factor 1 receptor inhibitor, for 3 weeks prior to rAAV-hSYN injection, maintaining it for 8 weeks to eliminate microglia.

Temperature-dependent toxicity and mechanisms of florfenicol on the embryonic development of marine medaka (Oryzias melastigma).

The extensive use of antibiotics and their persistence in the environment have seriously threatened marine ecosystems in recent years. The frequent occurrence of extreme weather due to climate change has also increased the uncertainty of effective toxicity identification and risk assessment of the chemicals of concern. This study aimed to investigate the toxic effects and potential mechanisms of florfenicol (0.

MIFS: An adaptive multipath information fused self-supervised framework for drug discovery.

The production of expressive molecular representations with scarce labeled data is challenging for AI-driven drug discovery. Mainstream studies often follow a pipeline that pre-trains a specific molecular encoder and then fine-tunes it. However, the significant challenges of these methods are (1) neglecting the propagation of diverse information within molecules and (2) the absence of knowledge and chemical constraints in the pre-training strategy.
