A comprehensive computational strategy that combined QSAR modelling, molecular docking, and ADMET analysis was used to discover potential inhibitors for β-secretase 1 (BACE-1). A dataset of 1,138 compounds with established BACE-1 inhibitory activities was used to build a QSAR model using mol2vec descriptors and support vector regression. The obtained model demonstrated strong predictive performance (training set:  = 0.

Recovery trajectories in intracerebral hemorrhage (ICH) are recognized as distinct from those observed in ischemic stroke. This narrative review aims to clarify the pathophysiology underlying ICH recovery patterns, highlighting the unique timeline and nature of functional improvements seen in ICH survivors. Population-based cohort studies tracking functional outcomes in a longitudinal fashion, along with randomized clinical trial data with standardized outcome assessments, have demonstrated that ICH recovery generally has a delayed onset in the first weeks, followed by a steep early subacute stage recovery (typically up to 3 months) continuing in protracted, gradual improvements beyond 3 to 6 months.

Article Synopsis
  • * Results suggested that while ECG-AF had a lower risk of IS recurrence within the first year after the stroke, over the longer term, there was no significant difference compared to KAF.
  • * Prolonged monitoring (AFDAS) consistently showed a lower risk for recurrent IS compared to KAF throughout the study, indicating potential advantages in identifying AF later on in terms of treatment outcomes.

Background: Acute lung injury (ALI) triggers the activation of pulmonary macrophages, which in turn produce excessive amounts of reactive oxygen species (ROS).

Results: We synthesized ROS-responsive red light-emitting carbon dots (RCMNs) that target lung macrophages, possess bioimaging capabilities, and efficiently eliminate intracellular ROS, thereby demonstrating anti-inflammatory effects for treating acute lung injury (ALI). In an LPS-induced ALI mouse model, RCMNs showed bioimaging and therapeutic potential, reducing lung damage and inflammation by targeting ROS-damaged tissue.

The stability and reversibility of Zn anode can be greatly improved by in situ construction of solid electrolyte interphase (SEI) on Zn surface via a low-cost design strategy of ZnSO electrolyte. However, the role of hydrogen bond acceptor -SO accompanying ZnS formation during SEI reconstruction is overlooked. In this work, we have explored and revealed the new role of -SO and ZnS in the in situ formed sulfide composite SEI (SCSEI) on Zn anode electrochemistry in ZnSO aqueous electrolytes.

Perovskite solar modules (PSMs) show outstanding power conversion efficiencies (PCEs), but long-term operational stability remains problematic. We show that incorporating -dimethylmethyleneiminium chloride into the perovskite precursor solution formed dimethylammonium cation and that previously unobserved methyl tetrahydrotriazinium ([MTTZ]) cation effectively improved perovskite film. The in situ formation of [MTTZ] cation increased the formation energy of iodine vacancies and enhanced the migration energy barrier of iodide and cesium ions, which suppressed nonradiative recombination, thermal decomposition, and phase segregation processes.

We present an ultraviolet (UV) - extreme-ultraviolet (XUV) pump-probe beamline with applications in ultrafast time-resolved photoelectron spectroscopy. The UV pump pulses, tuneable between 255 and 285 nm and with µJ-level energy, are generated by frequency up-conversion between ultrashort visible/infrared pulses and visible narrow-band pulses. Few-femtosecond XUV probe pulses are produced by a high-order harmonic generation source equipped with a state-of-the-art time-delay compensated monochromator.

The persistence of farmland plastic pollution has raised significant concerns regarding its potential long-term impacts on soil health in the context of global climate change. However, there are still gaps in the understanding of the impacts of plastic residues on soil microbial communities and functions in agricultural environments under unstable and extreme climatic conditions. In this study, the effects of plastic residues (two types and three shapes) on farmland soil bacterial communities and functions across varying environmental conditions were investigated through microscopic experiments.

Objective: In this study, we aim to explore the genetic imprint of Bronze Age globalization in East Asia from a phylogeographic perspective by examining the Y-chromosome haplogroup Q1a1a-M120, and to identify key demographic processes involved in the formation of early China and the ancient Huaxia people.

Methods: Over the past few decades, we have collected the sequences of 347 Y chromosomes from the haplogroup Q1a1a-M120. These sequences were utilized to analyze and reconstruct a highly revised phylogenetic tree with age estimates.

DDT (dichlorodiphenyltrichloroethane) is a commonly used insecticide that is recalcitrant and highly stable in the environment. Currently, DDT residue contamination, especially in agricultural soil, is still a concern in many countries, threatening human health and the environment. Among the approaches to resolve such an issue, novel biodegradation-based methods are now preferred to physicochemical methods, due to the sustainability and the effectiveness of the former.

  • Host microbes like Staphylococcus aureus (S. aureus) are becoming recognized as important factors in cancer, but their specific roles, especially in breast cancer, are not fully understood.
  • The study found that S. aureus infection leads to ineffective DNA damage response in breast cells, promoting tumor progression and metastasis through the activation of certain immune pathways.
  • Key findings show that S. aureus triggers receptors in breast cells, which activates the NF-κB p65 pathway, ultimately facilitating breast cancer cell spread and highlighting a connection between bacterial infections and cancer metastasis.

Platinum-based chemotherapy is the first-line treatment for tongue squamous cell carcinoma (TSCC), but most patients rapidly develop resistance. Circular RNAs (circRNAs) are a class of critical regulators in the pathogenesis of several tumors, but their role in cisplatin resistance in TSCC has not been fully elucidated. Here we found that circMAPKBP1 was enriched in cisplatin resistant TSCC cells and was closely associated with enhanced autophagic activity.

Durable response to chimeric antigen receptor T (CART) cell therapy remains limited in part due to CART cell exhaustion. Here, we investigate the regulation of CART cell exhaustion with three independent approaches including: a genome-wide CRISPR knockout screen using an in vitro model for exhaustion, RNA and ATAC sequencing on baseline and exhausted CART cells, and RNA and ATAC sequencing on pre-infusion CART cell products from responders and non-responders in the ZUMA-1 clinical trial. Each of these approaches identify interleukin (IL)-4 as a regulator of CART cell dysfunction.

Isolated attosecond pulse (IAP) generation usually involves the use of short-medium gas cells operated at high pressures. In contrast, long-medium schemes at low pressures are commonly perceived as inherently unsuitable for IAP generation due to the nonlinear phenomena that challenge favourable phase-matching conditions. Here we provide clear experimental evidence on the generation of isolated extreme-ultraviolet attosecond pulses in a semi-infinite gas cell, demonstrating the use of extended-medium geometries for effective production of IAPs.

Aqueous Mn-ion batteries (MIBs) exhibit a promising development potential due to their cost-effectiveness, high safety, and potential for high energy density. However, the development of MIBs is hindered by the lack of electrode materials capable of storing Mn ions due to acidic manganese salt electrolytes and large ion radius. Herein, the tunnel-type structure of monoclinic VO nanorods to effectively store Mn ions via a reversible (de)insertion chemistry for the first time is reported.
