Abstract
Nonylphenol (NP) is an organic pollutant and endocrine disruptor chemical that has harmful effects on the environment and living organisms. This study looked at whether kidney tissues subjected to increasing doses of nonylphenol generated alterations in histopathologic, pro-inflammatory, and autophagic markers. Fifty rats were divided into five groups of ten each: group I: healthy group, II: control (corn oil), group III: 25 μl/kg NP, group IV: 50 μl/kg NP, group V: 75 μl/kg NP. The kidney tissue samples were obtained for histopathological, immunohistochemical, and biochemical analyses. The histological deteriorations observed in all NP groups included tubular epithelial cell degeneration, inflammation areas, and hemorrhage. The immunohistochemical investigations showed that NP significantly elevated the autophagy markers (Beclin-1, LC3A/B, p62), pro-inflammatory cytokines (TNF-α, IL-6), HIF-1α, and eNOS in group III, IV and V compared with group I and II. The biochemical analysis also revealed that pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6) increased in correlation with the NP doses, but only IL-1β reached statistical significance in NP treated rats kidney tissue. The biochemical findings have been confirmed by the histological studies. The damage to renal tissue caused by NP exposure may worsen it by increasing inflammatory and autophagic markers.

Protective Effects of Boric Acid Taken in Different Ways on Experimental Ovarian İschemia and Reperfusion. Biol Trace Elem Res 2024; 202:2730-2743. [PMID: 37743417 DOI: 10.1007/s12011-023-03871-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 09/14/2023] [Indexed: 09/26/2023]
Abstract
Ovarian ischemia is a gynecological emergency that occurs as a result of ovarian torsion, affects women of reproductive age, and reduces ovarian reserve. The current study was designed to investigate the effect of boric acid taken in different ways on histopathological changes, autophagy, oxidative stress, and DNA damage caused by ischemia and reperfusion in the ovary of adult female rats. We established seven groups of 70 adult female rats: untreated control, intraperitoneal boric acid group (IpBA), oral boric acid group (OBA), ischemia/reperfusion group (ischemia/2 h reperfusion; OIR), ischemia/reperfusion and local boric acid group (OIR + LBA), ischemia/reperfusion and intraperitoneal boric acid group (OIR + IpBA), and ischemia/reperfusion and oral boric acid group (OIR + OBA). On the 31st day of the experimental procedure, both ovaries were harvested for histologic (hematoxylen and eosin and Masson trichrom), biochemical (ELISA and AMH, MDA, SOD, and CAT analyses), and comet evaluation. In the OIR group, hemorrhage, edema, inflammation, and diminished follicle reserve were seen in the ovary. Boric acid treatment reduced the ovarian ischemia/reperfusion damage, and the follicles exhibited similar morphological features to the control group. Moreover, boric acid treatment decreased the levels of Hsp70, NF-KB, COX-2, and CD31, which increased as a result of OIR. On the other hand, SCF and AMH levels, which decreased as a result of OIR, increased with boric acid treatment. The levels of autophagy markers (Beclin-1, LC3, and p62) reached values close to those of the control group. According to the biochemical findings, it was concluded that boric acid is also effective on oxidative stress, and the AMH level was particularly high in the OIR + OBA group, consistent with the immunohistochemical staining result. In addition, it was observed that the DNA damage caused by OIR reached values close to those of the control group, especially in the OBA after OIR. This study showed the therapeutic effects of boric acid on OIR injuries; thus, boric acid may be a potential therapeutic agent for ovarian protection and fertility preservation in cases that may cause ovarian torsion.

Abstract
Radiation has been widely used in many business sectors over the last century. Our study investigated the possible teratogenic effects of radiation on the bones of rat fetuses and the protective effect of melatonin against these effects. In this study, 15 pregnant female Wistar albino rats were used. These rats were divided into four groups: the control group, melatonin group (10 mg/kg/day), radiation group (0.5 gray), radiation (0.5 gray) + melatonin group (10 mg/kg/day), and sham group (1 mm hanks/day). The skeletal system development of fetuses was examined with double skeletal and scanning electron microscope (SEM), histopathological methods. In our study, fetal weight, placental weight, and fetal morphometric values were found to be statistically significantly decreased in the radiation group compared to the control group (p < .05). In immünohistochemistry (IHC) analysis, alkaline phosphatase, and tartrate-resistant acid phosphatase) concentrations were found to be significantly lower in the radiation group compared to the other groups. In the SEM analysis, it was observed that the amount of calcium and sodium decreased when the radiation group was compared with the other groups. As a result, when exposed to ionizing radiation during pregnancy, melatonin has a protective feature against the negative effects of radiation on the bone development of fetuses. RESEARCH HIGHLIGHTS: In our study, fetuses obtained from pregnant rats exposed to ionizing radiation were examined. In this study, the effect of melatonin on bone development in fetuses exposed to gray ionizing radiation was investigated. There are few studies on our subject in the literature. We believe that our findings will contribute to other planned studies.

Abstract
BACKGROUND AND OBJECTIVE Radiation therapy is a routine clinical practice that has been used for a long time in the treatment of cancer patients. The most important dose-limiting organ in patients receiving radiotherapy for various conditions is the brain. The mechanisms underlying brain and pituitary gland damage caused by radiation are largely unknown. It is of great importance to use radioprotective agents to protect against damage. This study aims to evaluate the neuroprotective effects of quercetin in experimental radiation-induced brain and pituitary gland damage. MATERIALS AND METHODS A total of 60 adult male Wistar-albino rats were randomly divided into six groups (control, sham, radiation, quercetin, radiation + quercetin, and quercetin + radiation groups, with ten rats in each group). Quercetin was given to rats by oral gavage at 50 mg/kg/day. A whole-body single dose of 10 Gy radiation was applied to the rats. Tissue samples belonging to the groups were compared after excision. Histopathological changes in the brain tissue and pituitary gland were examined with hematoxylin-tissue samples in the groups and compared histologically and immunohistochemically. RESULTS The histopathological examination of the brain and anterior pituitary gland sections showed marked damage in the radiation-treated rats, while the quercetin-administered groups showed normal tissue architecture. While neuropeptid Y immunoreactivity was increased, synaptophysin immunoreactivity was decreased in the brains of radiation-treated rats. However, when neuropeptide Y and synaptophysin expression were assessed in the anterior pituitary gland, there was no significant difference between the groups. CONCLUSION Consequently, quercetin may be a potential pharmacological agent in modulating radiation-induced damage in rats. However, extra experimental and preclinical studies are needed to confirm our findings before they can be used clinically.

Abstract
PURPOSE Hypocholesterolemic medications similar to atorvastatin are efficient in lowering blood lipid levels; however, compared to other medications in the statin family, their impact on bone metabolism is claimed to be insufficient. The impact of atorvastatin on bone regeneration in dental implantology in individuals with hyperlipidemia who received atorvastatin in the clinic is doubtful. METHODS In the study, 16 male New Zealand rabbits of 6 months were used. All rabbits were fed a high-cholesterol diet for 8 weeks, and hyperlipidemia was created. It was confirmed that the total cholesterol level in rabbits was above 105 mg/dl. A critical-sized defect was created in the mandible. The defect was closed with xenograft and membrane. Oral 10 mg/kg atorvastatin was started in the experimental group, and no drug was administered in the control group. At 16th week, animals were sacrificed. For histomorphological examination, the new bone area, osteoclast, and osteoblast activities were evaluated. RESULTS While new bone area (45,924 µm2, p < 0.001) and AP intensities (105.645 ± 16.727, p = 0.006) were higher in the atorvastatin group than in the control group, TRAP intensities in the control group (82.192 ± 5.346, p = 0.021) were higher than that in the atorvastatin group. CONCLUSIONS It has been found that high blood lipid levels will adversely affect bone graft healing and the use of systemic atorvastatin contributes to bone healing. Clinicians should pay attention to the selection of surgical materials, considering the importance of questioning drug use in their patients and the risks in cases of non-use.

Abstract
In this study, we reported boric acid's protective effects on the quality of nonylphenol (NP)-exposed oocytes. Female rats were classified into 4 groups: control, boric acid, NP, and NP+boric acid. Histopathological studies and immunohistochemical analysis of anti-müllerian hormone (AMH), mechanistic target of rapamycin (mTOR), Sirtuin1 (SIRT1), stem cell factor (SCF) studies were done. The comet assay technique was utilized for DNA damage. The ELISA method was used to determine the concentrations of oxidative stress indicators (SOD, CAT, and MDA), ovarian hormone (INH-B), and inflammation indicators (IL-6 and TNF-α). Boric acid significantly reduced the histopathological alterations and nearly preserved the ovarian reserve. With the restoration of AMH and SCF, boric acid significantly improved the ovarian injury. It downregulated SIRT1 and upregulated the mTOR signaling pathway. It provided DNA damage protection. Ovarian SOD, CAT levels were decreased by boric acid. Boric acid co-administration significantly reduced NP's MDA, IL-6, and TNF-activities. This results imply that boric acid has a protective role in ovarian tissue against NP-mediated infertility.

Abstract
Portulaca oleracea L. (P. oleracea) or purslane is a plant from the Portulacaceae family, which is used as food and traditional medicine for various diseases. This review article provides comprehensive information on the antioxidant, immunomodulatory, and anti-inflammatory properties of P. oleracea and its constituents. The literature survey of the different databases until the end of June 2023 was explored based on the keywords including the "P. oleracea, purslane, anti-inflammatory, immunomodulatory, and antioxidant properties." The plant contains flavonoids, alkaloids, terpenoids, fatty acids, vitamins, minerals, and some other compounds. The results indicated that P. oleracea and its constituents showed anti-inflammatory and immunomodulatory properties through reduction of inflammatory mediators including interferon gama (IFN-γ), interleukin (IL)-10, IL-4, tumor necrosis factor-alpha (TNF-α), and nitric oxide. Improvement in cytokines' serum levels (IFN-γ, IL-10, and IL-4) and increased IgG and IgM serum levels, as well as reduction of IgE, phospholipase A2, and total protein were demonstrated for P. oleracea. The plant and its constituents also improved oxidative stress by reduction of oxidant and increase of antioxidant markers. P. oleracea could be considered as an effective remedy for various inflammatory and immune diseases.

Abstract
Radiotherapy is one of the inevitable treatment approaches for several types of cancer. We aimed to show the protective and therapeutic effects of daily use of melatonin on liver tissues subjected to a single dose of 10 Gy (gamma-ray) total body radiation. Rats were divided into 6 groups, of which 10 were in each: control, sham, melatonin, radiation, radiation+melatonin, and melatonin+radiation. The rats received 10 Gy of external radiation throughout their entire bodies. The rats were given 10 mg/kg/day of melatonin intraperitoneally before or after radiation treatment, depending on the group. Histological methods, immunohistochemical analysis (Caspase-3, Sirtuin-1, α-SMA, NFΚB-p65), biochemical analysis by ELİSA (SOD, CAT, GSH-PX, MDA, TNF-α, TGF-β, PDGF, PGC-1α) and the Comet assay as a marker of DNA damage were applied to the liver tissues. Histopathological examinations showed structural changes in the liver tissue of the radiation group. Radiation treatment increased the immunoreactivity of Caspase-3, Sirtuin-1 and α-SMA, but these effects were relatively attenuated in the melatonin-treated groups. The melatonin+radiation group had statistically significant results close to those of the control group, in terms of Caspase-3, NFΚB-p65 and Sirtuin-1 immunoreactivity. In melatonin treated groups, hepatic biochemical markers, MDA, SOD, TNF-α, TGF-β levels, and DNA damage parameters were decreased. Administration of melatonin before and after radiation has beneficial effects, but using it before radiation may be more efficient. Accordingly, daily melatonin usage could mitigate ionizing radiation induced damage.

Correlation of chemokines and growth factors with radiation-induced liver injury after interstitial high dose rate (HDR) brachytherapy of liver metastases.

Abstract
Background Locoregional therapies, as imaging-guided tumor-directed procedures, are emerging treatment strategies in the management of primary and secondary liver malignancies such as e.g. colorectal cancer liver metastases. As one of those, irradiation-based interstitial high dose rate brachytherapy (iBT) of liver metastases bears a risk of developing focal radiation-induced liver injury (fRILI). Since little is known about biological factors involved in hepatic dysfunction after irradiation, the aim of this study was to identify factors, that may play a role in the underlying mechanism of fRILI, and that potentially may serve as biomarkers for post-therapeutic fRILI to improve specific management and treatment of patients. Methods Twenty-two patients with hepatic malignancies (tumor patients, TP) underwent iBT with total ablative doses of radiation to the target volume ranging from e.g. 15 to 25 Gy. Hepatobiliary magnetic resonance imaging (MRI) was performed 6 weeks after iBT to quanitify fRILI. Blood samples were taken before (pre) and 6 weeks after (post) iBT from TP, and from ten healthy volunteers (HV controls) for the analyses of humoral mediators: monocyte chemoattractant protein-1 (MCP-1), chemokine (C-X3-C motif) ligand 1 (CX3CL1), vascular endothelial growth factor (VEGF) and beta-nerve growth factor (beta-NGF) using the Multi-Analyte Flow Assay via flow cytometry. Correlation analyses between the humoral mediators (pre and post iBT) with the tumor volume and fRILI were performed. Results While MCP-1 and CX3CL1 tended to decrease in TP vs. HV, VEGF was significantly decreased in TP vs. HV pre and post iBT (p < 0.05). Beta-NGF levels were significantly increased in TP vs. HV pre and post iBT (p < 0.05). Baseline circulating levels of MCP-1, VEGF and beta-NGF have shown significant positive correlations with the hepatic tumor volume (p < 0.05). Circulating levels of humoral mediators before treatment did not correlate with fRILI, while CX3CL1 and VEGF after iBT have shown significant positive correlations with fRILI (p < 0.05). Conclusion Tumor volume and threshold dose of irradiation damage correlated positively with MCP-1 and VEGF as well as NGF and CX3CL, respectively. Thus, investigation of biological mediators in blood samples from tumor patients may provide an appropriate tool to predict fRILI after interstitial HDR brachytherapy of liver metastases.
