Iron-cerium co-doped carbon dots (Fe,Ce-CDs) were synthesized by one-step hydrothermal method using tartaric acid and L-tryptophan as ligands. Fe,Ce-CDs shows excellent peroxidase-like (POD) activity and nitrite (NO) can promote the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) to its blue oxidation product (oxTMB) due to the formation of ∙NO free radical. NO further react with oxTMB to form a yellow color via diazotization resulting in the absorbance Change at 450 nm.

In this study, we elucidated that wheat TaPEPC10, regulated by the transcription factor TabHLH86, reduces tolerance to cadmium (Cd) stress. To investigate the function and regulatory mechanism of phosphoenolpyruvate carboxylase (PEPC) genes in wheat under Cd stress, we employed bioinformatics approaches to identify 18 PEPC genes and predicted TaPEPC10 as a key responder based on its expression profile under Cd stress. We conducted phenotypic analyses and measured various physiological and biochemical indices in TaPEPC10 mutant wheat under Cd stress.

Background: Cardiac ischemia reperfusion (I/R) injury is a serious consequence of reperfusion therapy for myocardial infarction (MI). Peptidylarginine deiminase 4 (PAD4) is a calcium-dependent enzyme that catalyzes the citrullination of proteins. In previous studies, PAD4 inhibition protected distinct organs from I/R injury by preventing the formation of neutrophil extracellular traps (NETs) and attenuating inflammatory responses.

Microbial contamination of absorbable collagen membranes used in guided bone regeneration (GBR) may compromise healing outcomes. This study aimed to investigate whether the minimum inhibitory concentration (MIC) of hydrogen peroxide (HO) can improve the antibacterial effect of indocyanine green (ICG)-mediated antimicrobial photodynamic therapy (PDT) on absorbable collagen membranes while reducing the need for high HO concentrations. A laboratory-based model was developed using Streptococcus sanguinis and Staphylococcus aureus.

Wheat blast caused by the fungus (MoT) pathotype is a catastrophic disease that threatens global food security. Lately, was discovered as a blast resistance gene in wheat genotype S615. However, while has recently been cloned, the precise underlying biochemical and molecular mechanism by which this gene confers resistance against MoT, remains to be fully elucidated.
