Abstract
ABSTRACT Introduction : Acute kidney injury (AKI) is an important clinical issue that arouses global concerns, which puzzles clinicians and lacks effective drug treatment for AKI until the present. Melatonin has been well recognized to modulate the sleep-wake cycle and had the renal protective effect. However, there are still few clinical trials investigating the relationship between melatonin and AKI. The conclusions drawn in existing clinical studies are still inconsistent. The study systematically reviewed and assessed the efficacy of melatonin in preventing AKI. Methods : A systematic literature search was conducted in the PubMed, Embase, and Cochranelibrary on May 19, 2023. Eligible records were screened according to the inclusion and exclusion criteria. The risk ratio and the corresponding 95% confidence intervals were selected to evaluate the effects of melatonin on AKI. We pooled extracted data using a fixed- or random effects model based on a heterogeneity test. Results : Six randomized controlled trials regarding the use of melatonin in preventing kidney injury met our inclusion criteria. The pooled results showed that melatonin increased the estimated glomerular filtration rate, and effectively inhibited the occurrence of AKI. Melatonin tended to reduce the serum creatinine and urea nitrogen levels, but there was no statistical significance. Conclusions : Melatonin can increase the estimated glomerular filtration rate and effectively inhibit the occurrence of AKI. More well-designed randomized controlled trials are needed to verify the protective effect of melatonin in the future.

Abstract
Melatonin is a neurohormone that is mainly secreted by the pineal gland. It coordinates the work of the superior biological clock and consequently affects many processes in the human body. Disorders of the waking and sleeping period result in nervous system imbalance and generate metabolic and endocrine derangements. The purpose of this review is to provide information regarding the potential benefits of melatonin use, particularly in kidney diseases. The impact on the cardiovascular system, diabetes, and homeostasis causes melatonin to be indirectly connected to kidney function and quality of life in people with chronic kidney disease. Moreover, there are numerous reports showing that melatonin plays a role as an antioxidant, free radical scavenger, and cytoprotective agent. This means that the supplementation of melatonin can be helpful in almost every type of kidney injury because inflammation, apoptosis, and oxidative stress occur, regardless of the mechanism. The administration of melatonin has a renoprotective effect and inhibits the progression of complications connected to renal failure. It is very important that exogenous melatonin supplementation is well tolerated and that the number of side effects caused by this type of treatment is low.

Abstract
OBJECTIVES To examine the protective effects of melatonin on laryngeal radiation damage. MATERIALS AND METHODS 31 rats were divided into 4 groups as follows: 1) the control (C) group (n=7), was only injected with intraperitoneal ethanol solution; 2) the melatonin (M) group (n=8), was injected intraperitoneal melatonin solution with 5 mg/kg; 3) the radiotherapy (RT) group (n=8) was given laryngeal radiation after intraperitoneal injection of ethanol solution; 4) the M + RT group (n=8), RT was given 30 minutes after 5 mg/kg dose of melatonin solution was injected. Drug and radiation applications were continued for 5 days. The weight changes of the rats were recorded. At the end of the study, inflammation, neutrophil migration and lymphoid aggregates, collagen distribution, laryngeal glandular structures and biochemical analysis of laryngeal tissues [malondialdehyde (MDA), total oxidant status (TOS) and total antioxidant status (TAS)] were determined. RESULTS In the M+RT group, the first day and the 30th weight differences were significantly increased when compared with the RT group (p=0.050). Inflammation, neutrophil migration, lymphoid aggregate, disorganized collagen distribution and loss of glandular tissues were found statistically more in the RT group than in the C group (p<0.05). MDA and TOS levels were in the M + RT group exhibited better values than they did in the RT group (p<0.05). TAS levels was markedly increased in the M + RT group than in the RT group (p<0.001). CONCLUSION Administration of melatonin to rats prior receiving laryngeal radiation, decreases the level of oxidative stress markers and increases the level of anti-oxidative markers.

Abstract
This study aimed to elucidate the effects of amifostine (ethyol) (AM), a synthetic radioprotector, and red ginseng (RG), a natural radioprotective agent, against the toxic effect of ionizing radiation (IR) on kidney tissues through changes in biochemical and histopathological parameters in addition to contributions to the use of amifostine and RG in clinical studies . Five groups were established: Group I (control, receiving only saline by gavage), Group II (IR only), and Group III (IR+AM, 200 mg/kg intraperitoneally (i.p.). Group IV (IR + RG, 200 mg/kg orally once a day for 4 weeks), and Group V (IR+RG+AM, 200 mg/kg orally once/day for 4 weeks before IR and 200 mg/kg AM administered (i.p.) 30 min before IR). All groups, except for the control group, were subject to 6-Gy whole-body IR in a single fraction. 24 h after irradiation, all animals were sacrificed under anesthesia. IR enhanced MDA, 8-OHdG, and caspase-3 expression while decreasing renal tissue GSH levels ( p < .05). Significant numbers of necrotic tubules together with diffuse vacuolization in proximal and distal tubule epithelial cells were also observed. The examination also revealed substantial brush boundary loss in proximal tubules as well as relatively unusual glomerular structures. While GSH levels significantly increased in the AM, RG, and AM+RG groups, a decrease in KHDS, MDA, 8-OHdG, and caspase-3 expression was observed, compared to the group subject to IR only ( p < .05). Therefore, reactive oxygen species-scavenging antioxidants may represent a promising treatment for avoiding kidney damage in patients receiving radiation.

Abstract
More than half of cancer patients need radiotherapy during the course of their treatment. Despite the beneficial aspects, the destructive effects of radiation beams on normal tissues lead to oxidative stress, inflammation, and cell injury. Kidneys are affected during radiotherapy of abdominal malignancies. Radiation nephropathy eventually leads to the release of factors triggering systemic inflammation. Currently, there is no proven prophylactic or therapeutic intervention for the management of radiation-induced nephropathy. This article reviews the biomarkers involved in the pathophysiology of radiation-induced nephropathy and its underlying molecular mechanisms. The efficacy of compounds with potential radio-protective properties on amelioration of inflammation and oxidative stress is also discussed. By outlining the approaches for preventing and treating this critical side effect, we evaluate the potential treatment of radiation-induced nephropathy. Available preclinical and clinical studies on these compounds are also scrutinized.

Abstract
Prevention of oxidative stress and inflammation in chronic kidney disease patients (CKD) on dialysis may reduce dialysis-associated complications. Administration of powerful antioxidants may improve the consequences of peritoneal dialysis (PD) and hemodialysis (HD). This narrative review aimed to show the potential therapeutic effects of melatonin (MLT) on the consequences of CKD patients receiving HD or PD. The results of preclinical and clinical studies have proven that CKD and dialysis are accompanied by reduced endogenous MLT levels and related complications such as sleep disorders. Enhanced oxidative stress, inflammation, cellular damages, and renal fibrosis, along with dysregulation of the renin-angiotensin system (RAS), have been observed in CKD and patients on dialysis. Results of studies have revealed that the restoration of MLT via the exogenous source may regulate oxidative stress, inflammation, and RAS functions, inhibit fibrosis, and improve complications in patients with long-term dialysis patients. In summary, treatment of patients with CKD and dialysis with exogenous MLT is suggested as a practical approach in reducing the outcomes and improving the quality of life in patients via antioxidant, anti-inflammatory, and anti-fibrotic signaling pathways. Therefore, this hormone can be considered in clinical practice to manage dialysis-related complications.

Abstract
Radiation treatments often unfavorably damage neighboring healthy organs and cause a series of radiation sequelae, such as radiation-induced hematopoietic system diseases, radiation-induced gastrointestinal diseases, radiation-induced lung diseases, and radiation-induced skin diseases. Recently, emerging nanomaterials have exhibited good superiority for these radiation-induced disease treatments. Given this background, the rational design principle of nanomaterials, which helps to optimize the therapeutic efficiency, has been an increasing need. Consequently, it is of great significance to perform a systematic summarization of the advances in this field, which can trigger the development of new high-performance nanoradioprotectors with drug efficiency maximization. Herein, this review highlights the advances and perspectives in the rational design of nanomaterials for preventing and treating various common radiation-induced diseases. Furthermore, the sources, clinical symptoms, and pathogenesis/injury mechanisms of these radiation-induced diseases will also be introduced. Furthermore, current challenges and directions for future efforts in this field are also discussed.

Abstract
PURPOSE In this study, we evaluated the renal protective effects of montelukast (MLK) against ionizing radiation (IR) induced nephrotoxicity in mice. MATERIALS AND METHODS Radioprotective effects of MLK were assessed by biochemical analysis including measurements of kidney malondialdehyde (MDA), reduced glutathione (GSH), and serum creatinine and urea levels. Besides, for further evaluation of protective effects of MLK on renal system, 99m Tc-dimercaptosuccinic acid (DMSA) has been applied. The total antioxidant capacity of MLK was measured by using 1,1-diphenyl-2-picryl hydrazyl radical reagents and compared with butylated hydroxyl toluene standard antioxidant. RESULTS The biochemical evaluation revealed that better results have been achieved for the groups administered with MLK than the only radiation group. Besides only IR-treated mice group, those treated with MLK demonstrated a significant decrease in urea and creatinine levels. Statistically, significant differences of MDA and SHG levels (P < .05) were found between the radiation group and MLK plus IR-treated group. Also, 99m Tc-DMSA kidney uptake value (%ID/g) was observed lower for MLK plus IR-treated mice group than only radiation-treated mice group. CONCLUSIONS According to our findings, MLK has a potential role to be used as a renal protective agent against gamma radiation in radiotherapy.

Abstract
Abstract
Kidneys are one of the main dose-limiting organs in radiotherapeutic procedures of lower abdomen. Likewise, the threat of exposure of radiosensitive organs such as kidneys in warfare or radiation accidents among military personal or due to terrorist activities in general public is of increasing concern. These events warrant the need for appropriate animal models to study the acute and chronic effects of low- and high-dose rate radiation exposures. In this study, for the first time, we validated Tsc2+/– mouse model to study whether radiation accelerates carcinogenesis in kidneys. Tsc2+/– mice at increasing age groups at 8 and 10 months were exposed to repeated doses of gamma radiation (0.4 Gy × 5) and assessed for aggravated kidney tumor formation at 2 months post-irradiation. Animals from irradiated group showed a significant increase in numbers of bilateral, multifocal tumors compared with mock-irradiated animals. Intra-glomerular reactive oxygen species (ROS) levels measured by dihydroethidium florescence showed significant increases in ROS production in irradiated Tsc2+/– mice compared with non-irradiated animals. Similarly, selective hematological parameters and glomerular filtration rate were further reduced significantly in irradiated Tsc2+/– mice. Tsc2 protein, tuberin in irradiated mice, however, remains at the same reduced levels as that of the mock-irradiated heterozygous Tsc2 mice. The results indicate that radiation alters kidney homeostatic function and influences high spontaneous incidence of renal cell carcinoma in this rodent model. Repurposing of Tsc2+/– mice model will, therefore, provide a unique opportunity to study acute and delayed effects of radiation in the development of kidney cancers.

Abstract
AIMS As a source of growth factors and with its cytoprotective properties, platelet-rich plasma (PRP) received considerable attention in regenerative medicine. Thus, this study was designed to evaluate the protective efficacy of PRP against γ-radiation-induced nephrotoxicity. MAIN METHODS Forty male rats were distributed in four groups: 1) control, 2) PRP, 3) Radiation, and 4) PRP + radiation. Nephrotoxicity was examined in rats after a whole body γ-irradiation at a single dose of 8 Gy. Activated PRP (0.5 ml/kg BW) was injected subcutaneously twice weekly for three successive weeks prior to γ-irradiation. At the end of the experiment, creatinine, urea, albumin, and neutrophil gelatinase-associated lipocalin (NGAL) serum levels, as well as renal relative gene expression level of kidney injury molecule-1 (KIM-1) were estimated. Further, malondialdehyde level, nitric oxide content and reduced glutathione content in addition to superoxide dismutase and catalase activities were measured. Moreover, the expression levels of B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X (Bax), and caspase-3 proteins were assayed. KEY FINDINGS PRP pre-treatment significantly reduced the radiation-induced abnormalities in kidney histology and attenuated the induced cell injury. Furthermore, PRP notably ameliorated the state of oxidative stress and appeared to inhibit the induced apoptosis. SIGNIFICANCE This study lends a probable protective role of PRP against γ-radiation-induced nephrotoxicity which can highlight the possibilities of its application as a complementary procedure during radiotherapy.

Abstract
Taurine (2-aminoethanesulfonic acid) is a sulfur-containing organic acid possessing several important effects, including antioxidant and anti-inflammatory ones. Exposure to ionizing radiation generates free radicals and reactive oxygen species (ROS) in irradiated cells, and free radical generation leads to oxidative stress. It is known that radiation nephropathy includes an inflammation-based process in which ROS and cytokines are responsible. Different doses of explored radiation can cause apoptosis, inflammation and a profound oxidative stress in kidneys. Oxidative stress is involved in renal injury after exposure to both ionizing radiation and inflammation. In this review, we describe the protective effect of taurine against several kidney diseases and the potential effects of taurine in the mitigation of radiation nephropathy. We also report that X-irradiation decreased the expression of taurine and TauT in the kidney. Taurine administration suppressed the decrease in the expression of taurine and TauT in the kidney after radiation exposure. Taurine might contribute to the mitigation of kidney injury induced by radiation.

The aim of the present study was to investigate the effectiveness of melatonin and genistein in preventing radiation therapy (RT)-induced liver injury in mice. A total of 70 Swiss Albino male mice were divided into 7 equal groups (n=10/group) as follows: Melatonin (M group, G3), genistein (G group, G4), polyethylene glycol-400 (P group, G5), RT only (RT group, G2) and sham irradiation (C group, G1). RT plus genistein (RT+G group, G7) and RT plus melatonin (RT+M group, G6) were the co-treatment groups. Firstly, hepatic tissue damage was induced in mice via exposure to a single dose of 6-Gy irradiation. RT was performed with a cobalt-60 teletherapy machine (80 cm fixed source-to-surface distance, 2.5-cm depth). Melatonin was processed (100 mg/kg, intraperitoneal) 30 min before and genistein was administered (200 mg/kg, SC) one day prior to the single dose of irradiation. Six months following irradiation, all mice were sacrificed. The degree of liver injury was measured using histological liver sections. Liver injury was significantly worse in the RT group than in the control group (C; RT vs. C; P<0.05); however, liver injury decreased following co-treatment with melatonin or genistein vs. RT alone (RT+M and RT+G vs. RT; P<0.05). No difference was observed between the RT+M and RT+G groups (P>0.05). The present study revealed that melatonin and genistein administration prior to irradiation protects mice against liver injury, which may have therapeutic implications for RT-induced injuries.

Abstract
PURPOSE Kidneys are exposed to ionizing radiation during radiotherapy in patients with abdominal malignancy. The aim of this study is to investigate the protective effect of atorvastatin (ATV) against ionizing radiation-induced nephrotoxicity in mice. MATERIALS AND METHODS Sixty male BALB/c mice were randomly divided into six groups (10 mice per group); control, irradiation (IR), IR plus ATV (10, 20 and 50 mg/kg) and only ATV (50 mg/kg). ATV groups received ATV for seven days via oral gavage before exposure to IR. Animals were exposed to 2 Gy whole body of X-ray on day 8. After exposure to IR, biochemical, histological and immunohistological assays were performed. RESULTS ATV significantly decreased the level of oxidative stress biomarkers in irradiated mice in comparison with IR alone. A significant reduction in the urea and creatinine levels was observed in ATV plus IR group compared to IR alone. Tubular degeneration, glomerular atrophy, interstitial expansion and fibrosis were observed in irradiated mice. Tubular degeneration and atrophy in the kidneys of IR plus ATV group were less than IR group. In addition, pre-treated animal with ATV significantly showed reduction in caspase-3 immunoreactivity. CONCLUSION ATV has significant protective effect against radiation-induced nephrotoxicity in mice and is a promising medication for protection of patients during radiotherapy.

Abstract
Toxicity induced by radiation therapy is a curse for cancer patients undergoing treatment. It is imperative to understand and define an ideal condition where the positive effects notably outweigh the negative. We used a microarray meta-analysis approach to measure global gene-expression before and after radiation exposure. Bioinformatic tools were used for pathways, network, gene ontology and toxicity related studies. We found 429 differentially expressed genes at fold change >2 and p-value <0.05. The most significantly upregulated genes were synuclein alpha (SNCA), carbonic anhydrase I (CA1), X-linked Kx blood group (XK), glycophorin A and B (GYPA and GYPB), and hemogen (HEMGN), while downregulated ones were membrane-spanning 4-domains, subfamily A member 1 (MS4A1), immunoglobulin heavy constant mu (IGHM), chemokine (C-C motif) receptor 7 (CCR7), BTB and CNC homology 1 transcription factor 2 (BACH2), and B-cell CLL/lymphoma 11B (BCL11B). Pathway analysis revealed calcium-induced T lymphocyte apoptosis and the role of nuclear factor of activated T-cells (NFAT) in regulation of the immune response as the most inhibited pathways, while apoptosis signaling was significantly activated. Most of the normal biofunctions were significantly decreased while cell death and survival process were activated. Gene ontology enrichment analysis revealed the immune system process as the most overrepresented group under the biological process category. Toxicity function analysis identified liver, kidney and heart to be the most affected organs during and after radiation therapy. The identified biomarkers and alterations in molecular pathways induced by radiation therapy should be further investigated to reduce the cytotoxicity and development of fatigue.

Abstract
The aim of the present study was to compare the effects of melatonin and genistein on radiation-induced nephrotoxicity (RIN). A total of 70 Swiss Albino mice were divided into 7 groups. Five control groups were defined, which were sham irradiation (C, G1), radiation therapy only (RT, G2), melatonin (M, G3), genistein (G, G4) and polyethylene glycol-400 (G5), respectively. The co-treatment groups were the RT plus melatonin (RT+M, G6) and RT plus genistein (RT+G, G7) groups. Irradiation was applied using a cobalt-60 teletherapy machine (80-cm fixed source-to-surface distance, 2.5-cm depth). Melatonin was administered (100 mg/kg, intraperitoneal injection) 30 min before the single dose of irradiation, whereas genistein was administered (200 mg/kg, subcutaneous injection) 1 day before the single dose of irradiation. All the mice were sacrificed 6 months after irradiation. As an end point, the extent of renal tubular atrophy for each mouse was quantified with image analysis of histological sections of the kidney. Tissue malondialdehyde (MDA) levels were also measured in each animal. In the histopathological examination of the mouse kidneys, there was a statistically significant reduction (P<0.05) in the presence of tubular atrophy between the RT+M and RT+G groups and the RT group. There was a statistically significant increase in MDA levels in the irradiated versus sham groups (RT vs. C; P<0.05); however, MDA levels were significantly decreased by co-treatment with melatonin or genistein vs. RT alone (RT+M and RT+G vs. RT; P<0.05). In conclusion, the present experimental study showed that melatonin and genistein supplementation prior to irradiation-protected mice against RIN, which may have therapeutic implications for radiation-induced injuries.

Abstract
Stress is known to precipitate neuropsychiatric diseases, and depending upon its nature and intensity it can also influence the functioning of the immune system. Melatonin (N-acetyl-5-methoxy tryptamine) a pineal gland hormone and potent antioxidant is known to protect against many diseases. Effect of melatonin in stress-induced neuro-immunomodulation is not well elucidated. Therefore in the present study, the protective effects of melatonin were evaluated in restraint stress (RS)-induced behavioral and immunological changes in rats. RS for 1 h significantly reduces (i) percentage of open-arm entries and (ii) percentage of time spent on open-arm in elevated plus maze (EPM) test parameters (p < 0.01) and significant increase in MDA levels in brain homogenate when compared to non-RS control groups (p < 0.05). In immunological studies, both humoral and cell-mediated immune responses to antigen were significantly suppressed by RS for 1 h for 5 consecutive days, as evidenced by significant reduction in (i) anti-SRBC antibody titre, (ii) PFC counts, (iii) percentage change in paw volume, and (iv) Th1 (IFN-γ) and Th2 (IL-4) cytokine levels (p < 0.001 in all parameters). These RS-induced immunological changes were associated with significantly increased lipid peroxidation (MDA) levels in serum and significantly decreased activity of (i) SOD, (ii) CAT, and (iii) GSH levels in RS (X5)-exposed group (p < 0.02). Pretreatment with melatonin (10, 50, and 100 mg/kg) significantly reversed these RS-induced changes in EPM test parameters and humoral and cell-mediated immunological parameters, as well as oxidative stress markers in a dose-dependent manner by differential degrees (p < 0.001). Results are strongly suggestive of the involvement of free radicals during stress-induced neurobehavioral and immunological changes. These changes were significantly restored by melatonin pretreatment. We can conclude that melatonin may have a protective role during such stress-induced neuro-immunomodulation.

Abstract
BACKGROUND NPAS2 is a product of the circadian clock gene. It acts as a putative tumor suppressor by playing an important role in DNA damage responses, cell cycle control and apoptosis. Chronic lymphocytic leukemia (CLL) appears to be an apoptosis related disorder and alteration in the NPAS2 gene might therefore be directly involved in the etiology of CLL. Here, the Ala394Thr polymorphism (rs2305160:G>A) in the NPAS2 gene was genotyped and melatonin concentrations were measured in a total of seventy-four individuals, including thirty-seven CLL cases and an equal number of age- and sex-matched healthy controls in order to examine the effect of NPAS2 polymorphism and melatonin concentrations on CLL risk in a Pakistani population. MATERIALS AND METHODS Genotyping of rs2305160:G>A polymorphism at NPAS2 locus was carried out by amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). Melatonin concentrations were determined by enzyme linked immunosorbent assay (ELISA). Statistical analysis was performed using Statistical Package for Social Sciences software. RESULTS Our results demonstrated no association of the variant Thr genotypes (Ala/ Thr and Thr/Thr) with risk of CLL. Similarly, no association of rs2305160 with CLL was observed in either females or males after stratification of study population on a gender basis. Moreover, when the subjects with CLL were further stratified into shift-workers and non-shift-workers, no association of rs2305160 with CLL was seen in either case. However, significantly low serum melatonin levels were observed in CLL patients as compared to healthy subjects (p<0.05). Also, lower melatonin levels were seen in shift-workers as compared to non-shift-workers (p<0.05). There was no significant difference (p>0.05) in the melatonin levels across NPAS2 genotypes in all subjects, subjects with CLL who were either shift workers or non-shift-workers. General Linear Model (GLM) univariate analysis revealed no significant association (p>0.05) of the rs2305160 polymorphism of the NPAS2 gene with melatonin levels in any of the groups. CONCLUSIONS While low melatonin levels and shift-work can be considered as one of the risk factors for CLL, the NPAS2 rs2305160 polymorphism does not appear to have any association with risk of CLL in our Pakistani population.

Abstract
The aim of this study was focused on investigating the possible protective effect of erdosteine against gamma radiation-induced renal lesions in male albino rats. Twenty-eight albino rats were divided into four equal groups as follows: control group, irradiated group (animals subjected to whole-body gamma irradiation at a dose of 5 Gy), treated group (each rat received 100 mg/kg body weight once daily, orally by gastric tube, erdosteine for 1 week), and treated irradiated group (each rat received 100 mg/kg body weight once daily, orally by gastric tube, erdosteine for 1 week, then exposed to whole-body gamma irradiation at a dose of 5 Gy). The results revealed that the administration of erdosteine to rats before irradiation significantly ameliorated the changes occurred in kidney function (creatinine and urea) compared with irradiated group. Also the changes in serum tumor necrosis factor α, interleukin 1β, and interleukin 6 activities were markedly improved compared with the corresponding values of irradiated group. Kidney catalase and glutathione peroxidase (GPx) activities and reduced glutathione concentration showed approximately normal level when compared with the irradiated group. The histopathological results showed distinctive pattern of renal lesions in irradiated group, while in treated irradiated group the renal tissues showed relatively well-preserved architecture. Erdosteine acts in the kidney as a potent scavenger of free radicals to prevent or ameliorate the toxic effects of gamma irradiation as shown in the biochemical and histopathological changes and might provide substantial protection against radiation-induced inflammatory damage.

Abstract
In recent years, the negative impact of oxidative stress on fertility has become widely recognised. Several studies have demonstrated its negative effect on the number and quality of retrieved oocytes and embryos following in-vitro fertilisation (IVF). Melatonin, a pineal hormone that regulates circadian rhythms, has also been shown to exhibit unique oxygen scavenging abilities. Some studies have suggested a role for melatonin in gamete biology. Clinical studies also suggest that melatonin supplementation in IVF may lead to better pregnancy rates. Here we present a critical review and summary of the current literature and provide suggestions for future well designed clinical trials.
