Objective: To accelerate the onset of systemic lupus erythematosus in C57BL/6 mice by injecting cadmium chloride nanoemulsion and shorten the traditional modeling time.
Methods: Pristane cadmium chloride nanoemulsion was prepared, and 66 C57BL/6 mice were randomly divided into four groups. The pristane group was intraperitoneally injected with 0.6 mL of pristane blank nanoemulsion, the model group was injected with 0.6 mL of pristane cadmium chloride nanoemulsion, the Cadmium chloride control group was injected with 0.6 mL of cadmium chloride nanoemulsion, and the control group was injected with the same amount of 0.9% sodium chloride solution. Urine protein content, anti-dsDNA antibody content, Th1 cell/Th2 cell ratio, and kidney staining were detected in each group.
Results: The model group began to develop disease in the 4th week, the anti-dsDNA antibody level reached 566.71 ± 1.44 ng/L, and the proteinuria reached 245.38 ± 30.54 ng/mL. The model group showed an onset at least 5 weeks earlier than that in the pristane group. There was no significant difference in anti-dsDNA antibody content between Cadmium chloride control group and blank group. At the 12th week, the Th1/Th2 cell ratio in the model group significantly decreased, and the pathological changes in the kidneys were consistent with the typical manifestations of lupus in mouse models.
Conclusion: These results suggest that cadmium chloride promotes earlier onset of pristane-induced systemic lupus erythematosus in a C57BL/6 mouse model.

Introduction: Manganese-oxidizing bacteria (MOB) play a critical role in converting soluble Mn(II) to insoluble Mn(III/IV) oxides, which have been widely applied for environmental remediation, particularly in heavy metal pollution control. Therefore, the discovery of novel MOB strains is of great significance for advancing pollution mitigation and ecosystem restoration.
Methods: In this study, a manganese-oxidizing bacterial strain was isolated from Mn-contaminated soil near an electroplating factory using selective LB medium supplemented with 10 mmol/L manganese chloride (MnCl), and the Leucoberbelin Blue (LBB) assay was employed to screen and identify strains with strong Mn(II)-oxidation ability.

Background: Evaluation of the combined effects of endocrine-disrupting chemicals and dietary factors provides critical information for cumulative health risk assessment. Herein, we investigated the effects of cadmium (Cd) exposure and high fructose (HFr) diet on metabolic and reproductive health in female mice.
Methods: Female CD-1 mice were exposed to cadmium chloride (CdCl) (0.

Cadmium (Cd) is a respiratory toxicant. Previous reports have confirmed that chronic respiratory Cd exposure causes chronic obstructive pulmonary disease-like lesions in a murine model. This study aimed to evaluate the influence of short-term Cd exposure on lung function.

Heavy metal contamination in freshwater ecosystems poses persistent threats to aquatic organisms and public health. This study evaluates the transgenerational toxicity of cadmium chloride and copper sulfate on , focusing on development, reproduction, and midgut histopathology over two successive generations. Larval bioassays showed cadmium chloride to be more toxic than copper sulfate, with early instars exhibiting higher sensitivity (LC = 8.

Cadmium chloride (CdCl₂) is a powerful environmental toxin that has been documented to induce severe hepatic and renal damage through oxidative stress mechanisms. This study evaluated the protective impact of combined low dose of gamma irradiation (LDR) and trans-resveratrol (Trans-Res) on CdCl₂-induced hepato-renal toxicity in rats. Five groups of 50 male albino rats had been classified as; control, CdCl₂ (2 mg/kg), CdCl₂+LDR (0.
