Here, we characterize hemocyte subpopulations in before and after DIV1 infection at single-cell resolution.

Development and validation of a fusion model based on multi-phase contrast CT radiomics combined with clinical features for predicting Ki-67 expression in gastric cancer.

The present study aimed to develop and validate a fusion model based on multi-phase contrast-enhanced computed tomography (CECT) radiomics features combined with clinical features to preoperatively predict the expression levels of Ki-67 in patients with gastric cancer (GC). A total of 164 patients with GC who underwent surgical treatment at our hospital between September 2015 and September 2023 were retrospectively included and were randomly divided into a training set (n=114) and a testing set (n=50). Using Pyradiomics, radiomics features were extracted from multi-phase CECT images and were combined with significant clinical features through various machine learning algorithms [support vector machine (SVM), random forest (RandomForest), K-nearest neighbors (KNN), LightGBM and XGBoost] to build a fusion model.

Provoking tumor disulfidptosis by single-atom nanozyme via regulating cellular energy supply and reducing power.

Disulfidptosis, a recently identified form of programmed cell death, is initiated by depletion of endogenous nicotinamide adenine dinucleotide phosphate (NADPH) under glucose starvation. Tumor cells, owing to their heightened requirements of energy and nutrients, are more susceptible to disulfidptosis than normal cells. Here, we introduced an effective strategy to induce tumor disulfidptosis via interrupting cellular energy supply and reducing power by integrating a copper single-atom nanozyme (CuSAE) and glucose oxidase (GOx).

Three-stage phosphorus release model during macrophyte decomposition in macrophyte-dominated eutrophic lake.

Phosphorus (P) release during macrophyte decomposition plays a pivotal role in the lake phosphorus cycle, particularly in macrophyte-dominated eutrophic (MDE) lakes.

The conformational epitope of Ara h 5 was crucial to the severe reactivity of peanut allergy.

Conformational epitopes are associated with the development of food allergic tolerance and the severity of food allergy. Peanut can trigger severe anaphylactic reactions, however, the reason behind the severe allergic reactions caused by peanut remains unexplained. The purpose of this article was to provide an explanation for the severe allergy caused by peanut, focusing on the conformational epitopes of Ara h 5 and Ara h 8 allergens that exhibit cross-reactivity with asthma reactions.

Modeling microbial impact on macrophyte debris decomposition in macrophyte-dominated eutrophic lakes.

The decomposition of macrophytes plays a crucial role in the nutrient cycles of macrophyte-dominated eutrophication lakes. While research on plant decomposition mechanisms and microbial influences has rapid developed, it is curious that plant decomposition models have remained stagnant at the single-stage model from 50 years ago, without endeavor to consider any important factors. Our research conducted in-situ experiments and identified the optimal metrics for decomposition-related microbes, thereby establishing models for microbial impacts on decomposition rates (k_RDR).
