Exogenous Calcium Enhances Castor Tolerance to Saline-Alkaline Stress by Regulating Antioxidant Enzyme Activity and Activating Ca and ROS Signaling Crosstalk.

Saline-alkaline stress is a major factor limiting agricultural development, with calcium (Ca) playing a role in regulating plant tolerance through multiple signaling pathways. However, the specific mechanisms by which Ca mediates saline-alkaline stress tolerance at the molecular level remain incompletely understood. This study investigates the effects of exogenous Ca application on enhancing plant tolerance to saline-alkaline stress, focusing on its impact on the antioxidant system and Ca and reactive oxygen species (ROS) signaling pathways.

Spatially organized tumor-stroma boundary determines the efficacy of immunotherapy in colorectal cancer patients.

Colorectal cancer (CRC) patients with mismatch repair (MMR)-deficient (dMMR) but not MMR-proficient (pMMR) tend to benefit from immune checkpoint blockade (ICB) therapy. To profile the tumor microenvironments (TME) underlying these varied therapeutic responses, we integrate spatial enhanced resolution omics-sequencing (Stereo-seq), single-cell RNA sequencing, and multiplexed imaging analysis to create high-definition spatial maps of tumors from treatment-naïve and ICB-treated CRC patients. Our results identify the spatial organization and immune status of the tumor-stroma boundary as a distinctive feature of dMMR and pMMR CRCs, which associates with ICB response.

Artificial Neural Network Model for Predicting Mechanical Strengths of Economical Ultra-High-Performance Concrete Containing Coarse Aggregates: Development and Parametric Analysis.

Ultra-high-performance concrete with coarse aggregates (UHPC-CA) has the advantages of high strength, strong shrinkage resistance and a lower production cost, presenting a broad application prospect in civil engineering construction. In view of the difficulty in establishing a mathematical model to accurately predict the mechanical properties of UHPC-CA, the back-propagation artificial neural network (BP-ANN) method is used to fully consider the various influential factors of the compressive strength (CS) and flexural strength (FS) of UHPC-CA in this paper. By taking the content of cement (C), silica fume (SF), slag, fly ash (FA), coarse aggregate (CA), steel fiber, the water-binder ratio (), the sand rate (SR), the cement type (CT), and the curing method (CM) as input variables, and the CS and FS of UHPC-CA as output objectives, the BP-ANN model with three layers has been well-trained, validated and tested with 220 experimental data in the studies published in the literature.
