This study reports a novel hollow CuO@CuS material used as a catalyst for enzyme free glucose detection. CuO@CuS is successfully synthesized by a facile in-situ growth method. The obtained CuO@CuS exhibits a hollow structure with a CuS rich surface. Compared to CuO spheres, electrochemical results reveal that the CuO@CuS material exhibits a much higher catalytic activity toward glucose oxidation due to synergistic effect between CuO and CuS. The as-prepared CuO@CuS produces a high sensitivity, a fast sensing response, a wide linear range in concentrations of 1-1000 μM, and an excellent selectivity, thus prove to be a promising catalyst for enzyme free glucose detection.

Cotton is essential for the global textile industry however, climate change, especially extreme temperatures, threatens sustainable cotton production. This research aims to identify breeding strategies to improve heat tolerance and utilize stress-resistant traits in cotton cultivars. This study investigated heat tolerance for 50 cotton genotypes at the seedling stage by examining various traits at three temperatures (32 °C, 45 °C and 48 °C) in a randomized plot experiment.

Long noncoding RNAs (lncRNAs) are key regulators during gastric cancer (GC) development and may be viable treatment targets. In the present study, we showed that the expression of the long intergenic noncoding RNA 01016 (LINC01016) is significantly higher in GC tissues with lymph node metastasis (LNM) than those without LNM. LINC01016 overexpression predicts a poorer relapse-free survival (RFS) and overall survival (OS).

Hepatocellular carcinoma (HCC) is the most prevalent form of liver cancer, and ranks among the most lethal malignancies globally, primarily due to its high rates of recurrence and metastasis. Despite the urgency, no reliable biomarkers currently exist for predicting tumor recurrence in HCC. Telomerase reverse transcriptase (TERT) promoter mutations (TERTpm) and cellular tumor antigen p53 mutations (TP53m) have been frequently documented in HCC, but their combined clinical significance remains undefined.

Background: The threat of toxic malathion residues to human health has always been a serious food safety issue. The CRISPR/Cas system represents an innovative detection technology for pesticide residues, but its application to malathion detection has not been reported yet. In addition, the multiple-guide RNA (gRNA) powered-CRISPR/Cas biosensor has the advantages of being fast, sensitive and does not require pre-amplification.

Recently, multi-enzyme cascade catalysis has attracted increasing attention due to the advantages of integrating multiple enzymes, few side reactions and high catalytic efficiency. Herein, a novel dual-enzyme cascade system (GOx-FMt-HRP) was developed through cofactor-directed orientational co-immobilization of glucose oxidase (GOx) and horseradish peroxidase (HRP) onto functional montmorillonite (FMt). The presented method realizes the reconstitution of cofactors and apo-enzymes (enzymes without cofactors), which enables enzymes to be immobilized in specific orientations on the support, thereby effectively reducing changes in their conformation.
