Objective: To investigate the adverse effects of perinatal exposure to nonylphenol (NP) on the reproductive development of F1 male SD rats in sexual maturation period.
Methods: The pregnant rats were randomly divided into control, 50 mg/kg, 100 mg/kg, and 200 mg/kg NP groups respectively. NP was administered to dams by gavage from gestation day 7 to weaning period. Rat pups were sacrificed at postnatal day 55. The concentration of serum testosterone was measured by radioimmunoassay. The epididymis was subjected to the determination of sperm count and motility while the testis was submitted to histopathological and immunohistochemical analyses.
Results: Compared with control, the concentration of serum testosterone, sperm count and motility in the 200 mg/kg NP dose groups significantly decreased (P < 0.05), and the histopathological examination revealed that NP-treated groups had higher rates of maldeveloped siminiferous tubules, smaller amount of Sertoli cells and weaker spermatogenesis. The expression of proliferative cell nuclear antigen (PCNA) significantly decreased in the 200 mg/kg NP dose groups (P < 0.05). The expression of Arom in 100 mg/kg and 200 mg/kg NP dose groups was lower than that in control. There was no significant difference in ER expression between the control and NP-treated groups.
Conclusion: These findings indicated that 200 mg/kg Nonylphenol apparently damaged the reproductive development of F1 male SD rats in the sexual maturation period.

Background: The retinal degenerative diseases retinitis pigmentosa (RP) and atrophic age- related macular degeneration (AMD) are characterized by vision loss from photoreceptor (PR) degeneration. Unfortunately, current treatments for these diseases are limited at best. Genetic and other preclinical evidence suggest a relationship between retinal degeneration and inflammation.

Quinoa, rich in pharmacologically active ingredients, possesses the potential benefit in preventing cognitive impairments induced by hypoxia. In this study, the efficacy of quinoa ethanol extracts (QEE) consumption (200 and 500 mg/kg/d, respectively) against hypobaric hypoxia (HH)-induced cognitive deficits in mice was investigated. QEE significantly ameliorated hypoxic stress induced by HH, as evidenced by improvements in baseline indices and reductions in hypoxia-inducible factor 1α levels.

Introduction: Alzheimer's disease (AD) is a leading cause of dementia, characterized by progressive neurodegeneration and cognitive dysfunction. The disease aetiology is closely associated with proteinopathies, mitochondrial abnormalities, and elevated ROS generation, which are some of the primary markers for AD brains.
Objectives: The current research was intended to elucidate the chemical interaction of β-pinene against potential targets and evaluate its neuroprotective potential in ICV-STZ-induced sAD.

Gestational diabetes mellitus (GDM) significantly disrupts placental structure and function, leading to complications such as intrauterine growth restriction (IUGR) and preeclampsia. This study aimed to investigate the effects of GDM on placental histology, angiogenesis, and oxidative stress, as well as evaluate metformin's protective role in mitigating these changes. A total of 60 pregnant Sprague-Dawley rats were divided into four groups: control, metformin-treated, GDM, and GDM with metformin.

Background: Lead (Pb) could be toxic to the female reproductive system, and resveratrol (Res) may overcome this toxicity.
Objective: To investigate the Res impact on the catalase (), glutathione peroxidase (), and superoxide dismutase () gene expression in the ovary and on the Cat and Gpx enzyme activity in the serum of rats exposed to lead acetate.
Materials And Methods: In this experimental study, 33 female Wistar rats (8-10 wk, 180-200 gr) were divided into 6 groups: a control group (normal saline), a Res group (40 mg/kg), and a Pb group (lead acetate 30 mg/kg).
