Article Abstract
Objective: Heavy metals and environmental pollutants, such as cadmium chloride, congenital disorders, and certain diseases, can lead to infertility in men. In this study, the effects of lupeol (an active pentacyclic triterpenoid with antioxidant properties) on testicular injuries induced by cadmium chloride were investigated in male rats.
Materials And Methods: Lupeol was obtained from Sigma-Aldrich, and the experiment included 40 male Wistar rats divided into 8 groups (healthy control, healthy rats treated with 100, 200, and 400 mg/kg of lupeol, cadmium chloride, and three groups that received cadmium chloride and were treated with 100, 200, and 400 mg/kg of lupeol). After oral treatment, rats were anesthetized, and blood and testicular tissue sampling was done. Subsequent analysis of oxidative stress enzymes, such as malondialdehyde (MDA) and superoxide dismutase (SOD), testosterone, sperm motility, and Aquaporin 9 (AQ9) levels was performed using ELISA, histopathology, and immunohistochemistry techniques, respectively. Immunohistochemistry staining was done for expression of Aquaporin 9 in seminiferous tubules.
Results: The results showed that compared to the healthy control, cadmium chloride caused a significant decrease in SOD, testosterone, sperm motility, and sperm vitality, with severe destruction of spermatogenic tubes and a significant increase in MDA and AQ9 rate. Rats which were treated with cadmium chloride+400 mg/kg of lupeol showed a significant increase in SOD, testosterone, histopathology, sperm motility, and sperm vitality rate, and significant organization of spermatogenic tubes in testis tissue. There was also a decrease in MDA and AQ9 of rats that received high-dose lupeol. (p<0.001).
Conclusion: This study suggests that lupeol has a high potential for improving male reproduction and antioxidants in rats exposed to oxidative stress.

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.

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.
