Abstract
BACKGROUND Heavy metals are one of the environmental pollutants. Lead (Pb) is one of the most common of these heavy metals. In this study, it was aimed at investigating the effects of syringic acid (SA) against testicular toxicity in rats administered lead acetate (PbAc). METHODS In the present study, a total of 35 Sprague-Dawley rats, 7 in each group, were used. The rats were divided into 5 groups, with 7 male rats in each group. Rats were given PbAc and SA orally for 7 days. The effects of PbAc and SA on epididymal sperm quality and apoptosis, inflammation, oxidative stress and histopathological changes in testicular tissue were determined. RESULTS While PbAc disrupted the seminiferous tubules and produced atrophic images, SA corrected these histological abnormalities. PbAc adminisration significantly reduced the levels of SOD, GSH, GPx, CAT, NRF-2 and NQO1 and significantly increased the levels of MDA and 8-OHdG in the testicular tissue of rats, while SA improved this situation. NF-κB, TNF-α, IL-1β, NLRP3, RAGE, ATF6, PERK, IRE1, CHOP, and GRP78 genes expression levels increased with PbAc administration, however these levels decreased with SA administration. In addition, PbAc increased the levels of apoptotic markers Bax, Caspase-3 and APAF-1 and decreased the level of Bcl-2, while SA improved this situation. It was observed that PbAc significantly reduced sperm quality in rats, while SA positively affected sperm quality. CONCLUSION As a result, SA administered against PbAc-induced testicular dysfunction in rats can provide effective protection at doses of 25 mg/kg/bw and 50 mg/kg/bw.

ACS OMEGA 2023; 8:14792-14798.

Abstract
This study was planned to research the in vivo effects of lead (Pb) ions and sodium tetraborate (Na2B4O7) on G6PD and 6PGD, which are some of the enzymes of the pentose phosphate pathway, which carries vital importance for metabolism, and GR and GST, which are glutathione metabolism enzymes, and the in vitro effects of the same agents on the 6PGD enzyme. According to the in vivo analysis results, in comparison to the control group, the rat liver G6PD (p < 0.05), and 6PGD (p < 0.01) enzyme activities in the Na2B4O7 group were significantly lower. In addition, GR and GST enzyme activities were insignificantly lower in the Na2B4O7 group compared to the control group (p > 0.05). The Pb group had lower G6PD and 6PGD enzyme activity levels and higher GR and GST enzyme activity levels compared to the control group, while these changes did not reach statistical significance (p > 0.05). In the in vitro analyses of the effects of Pb ions on the 6PGD enzyme that was purified out of rat liver with the 2',5'-ADP-Sepharose 4B affinity chromatography method, it was determined that Pb ions (200-1200 μM) increased the rat liver 6PGD enzyme activity levels by 33%. On the other hand Na2B4O7 was not significantly effective on 6PGD activity. These results will also contribute to future studies in understanding the physiopathology of the states triggered by Pb ions and sodium tetraborate (Na2B4O7).

Abstract
One of the most prevalent harmful heavy metals is lead (Pb). It is generally recognized to be harmful to the testicles. Asparagus officinalis has many saponins, flavonoids, and other phenolics with strong antioxidant and anti-inflammatory effects. The effects of A. officinalis (asparagus) aqueous extract (AOAE) on testicular damage caused by lead acetate (PbAc) were investigated in this study. In this way, 20 mg/kg PbAc was injected intraperitoneally 2 h after mice were administered 400 mg/kg AOAE orally for 14 days. In the biochemical analysis of testicular tissue, PbAc decreased enzymatic and nonenzymatic antioxidant molecules in testicular tissue, while increasing lipid peroxidation, nitric oxide, inflammatory markers [nuclear factor kappa-B (NF-κB), tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1 β), IL-6, and inducible nitric oxide synthase (iNOS)], and apoptotic-related proteins. Additionally, PbAc was discovered to reduce sperm motility and increase the percentage of dead sperm. However, due to its antioxidant qualities, AOAE has been found to reduce oxidative stress, therefore protecting against inflammation and apoptosis. It also allowed the AOAE sperm parameters to restore to their previous values in the control group. According to the findings, AOAE could be a natural substance that could be used to treat Pb-induced testicular toxicity; this protection may be attributed to its anti-oxidative, anti-inflammatory, and anti-apoptotic effects. However, this study warrants further works to explore in detail the underlying mechanisms of the alleviating effects of AOAE against Pb-induced toxicity and which of its active ingredients is responsible for this protection.

Abstract
The ability of the body to maintain homeostasis requires constant communication between the brain and peripheral tissues. Different organs produce signals, often in the form of hormones, which are detected by the hypothalamus. In response, the hypothalamus alters its regulation of bodily processes, which is achieved through its own pathways of hormonal communication. The generation and transmission of the molecules involved in these bi-directional axes can be affected by redox balance. The essential trace element selenium is known to influence numerous physiological processes, including energy homeostasis, through its various redox functions. Selenium must be obtained through the diet and is used to synthesize selenoproteins, a family of proteins with mainly antioxidant functions. Alterations in selenium status have been correlated with homeostatic disturbances in humans and studies with animal models of selenoprotein dysfunction indicate a strong influence on energy balance. The relationship between selenium and energy metabolism is complicated, however, as selenium has been shown to participate in multiple levels of homeostatic communication. This review discusses the role of selenium in the various pathways of communication between the body and the brain that are essential for maintaining homeostasis.

Pergularia tomentosa coupled with selenium nanoparticles salvaged lead acetate-induced redox imbalance, inflammation, apoptosis, and disruption of neurotransmission in rats’ brain. OPEN CHEM 2022.

Abstract
Abstract
In this study, the neuroprotective potential of either Pergularia tomentosa leaf methanolic extract (PtE) alone or in combination with selenium nanoparticles (SeNPs-PtE) was investigated against lead acetate (PbAc)-induced neurotoxicity. Experimental rats were pretreated with PtE (100 mg/kg) or SeNPs-PtE (0.5 mg/kg) and injected intraperitoneally with PbAc (20 mg/kg) for 2 weeks. Notably, SeNPs-PtE decreased brain Pb accumulation and enhanced the level of dopamine and the activity of AChE compared to the control rats. In addition, elevated neural levels of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, and glutathione along with decreased lipid peroxidation levels were noticed in pretreated groups with SeNPs-PtE. Moreover, SeNPs-PtE significantly suppressed neural inflammation, as indicated by lower levels of interleukin-1 beta, interleukin-6, tumor necrosis factor-alpha, nuclear factor-kappa B p65, and nitric oxide in the examined brain tissue. The molecular results also unveiled significant down-regulation in iNOS gene expression in the brains of SeNPs-PtE-treated rats. In addition, SeNPs-PtE administration counteracted the neural loss by increasing B-cell lymphoma 2 (Bcl-2) and brain-derived neurotrophic factor levels as well as decreasing BCL2-associated X protein and caspase-3 levels. To sum up, our data suggest that P. tomentosa extract alone or in combination with SeNPs has great potential in reversing the neural tissue impairment induced by PbAc via its antioxidant, anti-inflammatory, and anti-apoptotic activities. This study might have therapeutic implications in preventing and treating several lead-induced neurological disorders.
