Article Abstract
The mechanisms of cadmium (Cd) uptake and redistribution throughout the peanut lifecycle remain unclear. This study employed multi-isotope labeling techniques in hydroponic and soil-foliar systems, revealing that Cd uptake during podding (Cd) constituted 73.7% of kernel Cd content, whereas contributions from the flowering (Cd) and seedling (Cd) stages were 22.2 and 4.1%, respectively. Stem-stored Cd (Cd) contributes 53.2% to kernel Cd accumulation, while leaf-stored Cd (Cd) contributes 46.8%. Prestored Cd in shoots demonstrated the most efficient transport to pods, approximately twice that of Cd and Cd. Cd and Cd were predominantly stored in leaves (51.0%), while Cd mainly in stems (46.3%), 2.8 times its presence in leaves (16.5%), indicating distinct root-stem-kernel translocation. In the transfer of shoot Cd from stems to pods, 29.3% of Cd and 25.0% of Cd were exported. This study provides novel insights into Cd dynamics in peanuts, establishing a foundation for future Cd regulation strategies.

Cadmium-Induced Bone Toxicity: Deciphering the Osteoclast-Osteoblast Crosstalk.

Cadmium (Cd), a pervasive environmental and industrial toxicant, bioaccumulates and exerts severe detrimental effects on skeletal integrity across diverse animal species. Cd-induced bone injury manifests as osteoporosis, osteomalacia, and increased fracture risk, posing significant health and welfare concerns for wildlife and livestock inhabiting contaminated ecosystems. The pathogenesis hinges critically on the disruption of bone remodeling, a tightly regulated process orchestrated by osteoclasts (OCs) responsible for bone resorption and osteoblasts (OBs) responsible for bone formation.

Cadmium (Cd), a highly toxic non-essential heavy metal, disrupts cellular processes even at low concentrations. The current studies of Cd stress rely on whole-plant models with prolonged treatments, obscuring early response signals. Tobacco, a typical model plant, lacks protoplast-level investigations under Cd stress.

Cadmium (Cd) pollution in farmland soils threatens food safety, making it essential to study soil-crop Cd transport mechanisms and develop remediation strategies. While organosilicon-modified materials demonstrate potential in blocking metal uptake by crops, their underlying mechanisms remain underexplored. This study employed stable isotope Cd tracing to investigate Cd absorption, translocation, allocation in soil-pakchoi system mediated by organosilicon (DMDCS and D6).

Microplastics (MPs), as wastes derived from various plastic commodities, have distinct heterogeneity in their sources. The overlook of MP sources may decrease the prediction reliability of their carrier-effects and the execution efficiency of their refined control. Hence, this study focuses the influence of source heterogeneity on the Cd(II) carrier-effect of MPs, aiming to improve the insights on Cd(II)-pollution pattern reshaped by MPs.

This study investigates the association between chronic heavy metal exposure (lead [Pb], arsenic [As], cadmium [Cd]) and major adverse cardiovascular events (MACE) using data from 15,342 participants in the 2003-2018 NHANES survey. Utilizing eight machine learning algorithms (including logistic regression, Random Forest, XGBoost, and LightGBM) combined with SHapley Additive exPlanations (SHAP) analysis, we evaluated the impact of these metals on angina, myocardial infarction (MI), and heart failure (HF), while adjusting for demographic and socioeconomic confounders. Results identified cadmium as the predominant risk factor across all cardiovascular outcomes: RandomForest achieved optimal angina prediction, XGBoost highlighted Cd's strongest association with MI, and LightGBM confirmed Cd's dominance in HF risk stratification.
