Abstract
Cadmium (Cd) is a toxic heavy metal with significant environmental health hazards. It enters the body through various routes with tissue accumulation. The relatively longer half-life with slow body clearance significantly results in hepatotoxicity during its liver detoxification. Therefore, researchers are exploring the potential use of herbal-derived phytocomponents to mitigate their toxicity. Here, we investigated, for the first time, the possible ameliorative effect of the phytochemical Morin (3,5,7,29,49-pentahydroxyflavone) against acute Cd-induced hepatotoxicity while resolving its underlying cellular mechanisms in a rat animal model. The study involved 50 adult male Sprague-Dawley rats weighing 200-250 g. The animals were divided into five equal groups: control, Cd, Morin100 + Cd, Morin200 + Cd, and Morin200. The 2nd, 3rd, and 4th groups were intraperitoneally treated with Cd (6.5 mg/kg), while the 3rd, 4th, and 5th groups were orally treated with Morin (100 and 200 mg/kg) for 5 consecutive days. On the 6th day, hepatic function (serum ALT, AST, ALP, LDH enzyme activities, and total bilirubin level) testing, transcriptome analysis, and immunohistochemistry were performed to elucidate the ameliorative effect of Morin on hepatotoxicity. In addition to restoring liver function and tissue injury, Morin alleviated Cd-induced hepatic oxidative/endoplasmic reticulum stress in a dose-dependent manner, as revealed by upregulating the expression of antioxidants (SOD, GSH, Gpx, CAT, and Nrf2) and decreasing the expression of ER stress markers. The expression of the proinflammatory mediators (TNF-α, IL-1-β, and IL-6) was also downregulated while improving the anti-inflammatory (IL-10 and IL-4) expression levels. Morin further slowed the apoptotic cascades by deregulating the expression of pro-apoptotic Bax and Caspase 12 markers concomitant with an increase in anti-apoptotic Blc2 mRNA expression. Furthermore, Morin restored Cd-induced tissue damage and markedly suppressed the cytoplasmic expression of JNK and p-PERK immunostained proteins. This study demonstrated the dose-dependent antioxidant hepatoprotective effect of Morin against acute hepatic Cd intoxication. This effect is likely linked with the modulation of upstream p-GRP78/PERK/ATF6 pro-apoptotic oxidative/ER stress and the downstream JNK/BAX/caspase 12 apoptotic signaling pathways.

Abstract
This study aimed to examine the protective role of nebivolol (NEB) on liver tissue against the lipopolysaccharide (LPS)-induced sepsis model in rats by targeting endoplasmic reticulum (ER) stress-related binding immunoglobulin protein (Bip), CCAAT-enhancer-binding protein homologous protein (Chop) signaling pathways. Four groups, each comprising eight rats, were established: control, LPS, LPS + NEB, and NEB. Biochemical analyses included total oxidant status (TOS), serum aspartate transaminase (AST), and alanine aminotransferase (ALT) levels. Additionally, genetic assessments involved Chop and Bip/GRP78 mRNA expression levels, while histopathological examinations were conducted. Immunohistochemistry was used to determine interleukin-1 beta (IL-1 β) and caspase-3 levels. The LPS group exhibited significantly higher AST, ALT, oxidative stress index, and TOS levels compared to the control group. Moreover, the LPS group demonstrated markedly increased Chop and Bip/GRP78 mRNA expression compared to the control group. Immunohistochemical analysis of the LPS group revealed significant upregulation in IL-1β and caspase-3 expressions compared to the control group. Additionally, the LPS group showed significant hyperemia, mild hemorrhage, and inflammatory cell infiltrations. Comparatively, the LPS+NEB group exhibited a reversal of these alterations when compared to the LPS group. Collectively, our findings, suggest that NEB holds promise as a treatment in conditions where oxidative damage, inflammation, and ER stress-related apoptosis play significant roles in the pathogenesis.

Abstract
Cadmium (Cd) is recognized as being linked to several liver diseases. Currently, due to the limited spectrum of drugs available for the treatment of Cd intoxication, developing and designing antidotes with superior detoxification capacity and revealing their underlying mechanisms remains a major challenge. Therefore, we developed the first next-generation probiotic E. coli 1917-pSK18a-MT that delivers metallothionein (MT) to overcome Cd-induced liver injury in C57BL/6 mice by utilizing bacterial surface display technology. The results demonstrate that E. coli 1917-pSK18a-MT could efficiently express MT without altering the growth and probiotic properties of the strain. Moreover, we found that E. coli 1917-pSK18a-MT ameliorated Cd contamination-induced hepatic steatosis, inflammatory cell infiltration, and liver fibrosis by decreasing the expression of aminotransferases along with inflammatory factors. Activation of the Nrf2-Keap1 signaling pathway also further illustrated the hepatoprotective effects of the engineered bacteria. Finally, we showed that E. coli 1917-pSK18a-MT improved the colonic barrier function impaired by Cd induction and ameliorated intestinal flora dysbiosis in Cd-poisoned mice by increasing the relative abundance of the Verrucomicrobiota. These data revealed that the combination of E. coli 1917 and MT both alleviated Cd-induced liver injury to a greater extent and restored the integrity of colonic epithelial tissues and bacterial dysbiosis.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2023; 334:122250. [PMID: 37487871 DOI: 10.1016/j.envpol.2023.122250] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 07/13/2023] [Accepted: 07/22/2023] [Indexed: 07/26/2023]
Abstract
Microplastics (MPs) are a newly emerging type of pollutants. To date, MPs have been found in the atmosphere, soil, water, and even in human samples, posing a non-negligible threat to humans. Furthermore, multiple heavy metals have been found to co-exist with MPs or be absorbed by MPs. This leads to a widespread concern about their combined toxicity, which is currently elusive. Herein, we investigated the single or combined toxic effects of polystyrene MPs (PS-MPs) and cadmium chloride (CdCl2) on the liver and hepatocytes. After co-incubation, cadmium (Cd) can be absorbed by PS-MPs, resulting in physiochemical alterations of PS-MPs. In vivo and in vitro experiments revealed that PS-MPs solely or together with CdCl2 induced ferroptosis in hepatocytes, a newly defined programmed cell death characterized by lipid oxidation and iron accumulation. PS-MPs exerted more ferroptotic effect on hepatocytes than CdCl2, and combined exposure to PS-MPs and CdCl2 enhanced their ferroptotic effect, mainly by stimulating reactive oxygen species (ROS) production and inhibiting antioxidant activity. Upon single or combined exposure to PS-MPs and CdCl2, the induction of ferroptosis in hepatocytes can be inhibited by N-acetyl-cysteine (NAC, an ROS scavenger), deferoxamine (DFO, an iron chelator), and particularly ferrostatin-1 (Fer-1, a specific ferroptosis inhibitor). Fer-1 efficiently rescued the cell viability of hepatocytes upon exposure to PS-MPs and CdCl2 through enhancing the antioxidant system via upregulating GPX4 and SLC7A11. These findings would contribute to an in-depth understanding of the single and combined toxicity of microplastics and cadmium.

Exploring the role of ATP-sensitive potassium channel, eNOS, and P-glycoprotein in mediating the hepatoprotective activity of nicorandil in methotrexate-induced liver injury in rats. Immunopharmacol Immunotoxicol 2023; 45:607-615.

Abstract
BACKGROUND Methotrexate (MTX) is a commonly used chemotherapeutic agent; however, its clinical use is challenged by various types of injuries, including hepatotoxic side effects. Therefore, finding new protective drugs against MTX-induced toxicities is a critical need. Moreover, the different mechanisms mediating such effects are still not clear. The current study aimed to evaluate the possible ameliorative action of nicorandil (NIC) in MTX-induced hepatotoxicity and examine the roles of the ATP-sensitive potassium channel (KATP), endothelial nitric oxide synthase (eNOS), and P-glycoprotein (P-gp). MATERIALS AND METHODS Thirty-six male Wistar albino rats were used. NIC (3 mg/kg/day) was given orally for 2 weeks, and hepatotoxicity was induced by a single intraperitoneal injection of MTX (20 mg/kg) on the 11th day of the experiment. We confirmed the role of KATP by co-administering glimepiride (GP) (10 mg/kg/day) 30 min before NIC. The measured serum biomarkers were [alanine transaminase (ALT) and aspartate transaminase (AST)], total antioxidant capacity (TAC), malondialdehyde (MDA), nitric oxide (NOx), tumor necrosis factor-alpha (TNFα), superoxide dismutase (SOD), and P-gp. Histopathology, eNOS, and caspase-3 immunoexpression were evaluated. RESULTS The MTX group displayed hepatotoxicity in the form of elevations of ALT, AST, MDA, NOx, and caspase-3 immunoexpression. Furthermore, the histopathological examination showed marked liver injury. TAC, SOD, P-gp, and eNOS immunoexpression showed significant inhibition. In the protective group, all parameters improved (P value < 0.05). CONCLUSION NIC has an ameliorative action against MTX-induced hepatotoxicity, most probably via its antioxidant, anti-inflammatory, and anti-apoptotic functions together with the modulation of the KATP channel, eNOS, and P-glycoprotein.

Abstract
This study aimed to investigate the potential of nebivolol in preventing doxorubicin-induced cardiotoxicity by targeting the inflammatory, oxidative, and apoptotic pathways. Twenty-eight male rats were randomly divided into four groups, each consisting of seven rats. The control group received standard diets and unrestricted access to water. The rats in the normal saline (N/S) group were administered a 0.9% normal saline solution for two weeks. The doxorubicin group (the "induced group") received doxorubicin at a dosage of 2.5 mg/kg three times per week for two weeks. The nebivolol group received an oral dose of 4 mg/kg of nebivolol for the same duration. The cardiac tissues of rats treated with doxorubicin exhibited increased levels of tumor necrosis factor, interleukin-1, malondialdehyde, and caspase-3 compared to the normal saline control group (p<0.05), along with decreased levels of total antioxidant capacity and Bcl-2. These results show that doxorubicin is harmful to the heart. The administration of nebivolol significantly reduced the cardiotoxic effects induced by doxorubicin, as indicated by a statistically significant decrease in the levels of inflammatory markers, specifically tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) (p<0.05). The nebivolol group exhibited a significant decrease in malondialdehyde levels, which serves as a signal of oxidation, in cardiac tissue compared to the doxorubicin-only group (p<0.05). Additionally, the nebivolol group showed a significant increase in overall antioxidant capacity. Nebivolol dramatically attenuated doxorubicin-induced cardiotoxicity in rats, likely by interfering with oxidative stress, the inflammatory response, and the apoptotic pathway.

Abstract
Cadmium (Cd), a highly toxic pollutant, impairs oocyte fertilization, through oxidative damage on cumulus cells (CCs). This study analysed the transcriptomic profile of CCs of cumulus-oocyte complexes (COCs) from adult and prepubertal sheep, exposed to Cd nanomolar concentration during in vitro maturation. In both age-groups, CCs of matured oocytes underwent RNA-seq, data analysis and validation. Differentially expressed genes (DEGs) were identified in adult (n = 99 DEGs) and prepubertal (n = 18 DEGs) CCs upon Cd exposure. Transcriptomes of adult CCs clustered separately between Cd-exposed and control samples, whereas prepubertal ones did not as observed by Principal Component Analysis. The transcriptomic signature of Cd-induced CC toxicity was identified by gene annotation and literature search. Genes associated with previous studies on ovarian functions and/or Cd effects were confirmed and new genes were identified, thus implementing the knowledge on their involvement in such processes. Enrichment and validation analysis showed that, in adult CCs, Cd acted as endocrine disruptor on DEGs involved in hormone biosynthesis, cumulus expansion, regulation of cell signalling, growth and differentiation and oocyte maturation, whereas in prepubertal CCs, Cd affected DEGs involved in CC development and viability and CC-oocyte communications. In conclusion, these DEGs could be used as valuable non-invasive biomarkers for oocyte competence.

Abstract
Methotrexate (MTX) is an effective chemotherapeutic agent against a wide range of tumors and autoimmune diseases; however, hepatotoxicity limits its clinical use. Oxidative stress and inflammation have been implicated in the pathogenesis of MTX-induced hepatotoxicity. Paeonol is a natural phenolic compound reported for its antioxidant and anti-inflammatory properties. The current study aimed to investigate the protective effect of paeonol against MTX-induced hepatotoxicity in rats and various mechanisms that underlie this postulated effect. Paeonol was administered orally in a dose of 100 mg/kg, alone or along with MTX, for 10 days. Hepatotoxicity was induced via a single intraperitoneal dose of MTX (20 mg/kg) on day 5 of the experiment. Concomitant administration of paeonol with MTX significantly ameliorated distorted hepatic function and histological structure, restored hepatic oxidative stress parameters (MDA, NO, and SOD), and combated inflammatory response (iNOS and TNF-α). Additionally, paeonol enhanced cell proliferation and survival, evidenced by upregulating the proliferating cell nuclear antigen (PCNA) and suppressing apoptosis and the disposition of collagen fibers in rat livers treated with MTX. Importantly, paeonol upregulated the drug efflux transporters, namely P-glycoprotein (P-gp) and the multidrug resistance-associated protein 2 (Mrp-2) in MTX-treated rats. In conclusion, paeonol offered a potent protective effect against MTX-induced hepatotoxicity through suppressing oxidative stress, inflammation, fibrosis, and apoptosis pathways, along with P-gp and Mrp-2 upregulation.

Abstract
Hepatic ischemia/reperfusion (HIR) is the most common type of liver injury following several clinical situations. Modulating oxidative stress and inflammation by Nrf2/HO-1 and TLR4/MYD88/NF-κB pathways, respectively, is involved in alleviating HIR injury. Paeonol is a natural phenolic compound that demonstrates significant antioxidant and anti-inflammatory effects. The present study explored the possible protective effect of paeonol against HIR injury and investigated its possible molecular mechanisms in rats. Rats were randomly divided into four groups: sham-operated control, paeonol-treated sham-operated control, HIR untreated, and HIR paeonol-treated groups. The results confirmed that hepatic injury was significantly aggravated biochemically by elevated serum levels of alanine transaminase and aspartate transaminase, as well as by histopathological alterations, while paeonol reduced the increase in transaminases and alleviated pathological changes induced by HIR. Additionally, paeonol inhibited the HIR-induced oxidative stress in hepatic tissues by decreasing the upraised levels of malondialdehyde and nitric oxide and enhancing the suppressed levels of reduced glutathione and superoxide dismutase activity. Furthermore, paeonol activated the protective antioxidative Nrf2/HO-1 pathway. The protective effect of paeonol was associated with inhibiting the expression of the inflammatory key mediators TLR4, MYD88, NF-κB, and TNF-α. Finally, paeonol inhibited the increased mRNA levels of the pro-apoptotic marker Bax and enhanced the reduced mRNA levels of the anti-apoptotic marker Bcl-2. Taken together, our results proved for the first time that paeonol could protect against HIR injury by inhibiting oxidative stress, inflammation, and apoptosis.

Nebivolol elicits a neuroprotective effect in the cuprizone model of multiple sclerosis in mice: emphasis on M1/M2 polarization and inhibition of NLRP3 inflammasome activation. Inflammopharmacology 2022; 30:2197-2209. [PMID: 35948811 DOI: 10.1007/s10787-022-01045-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Accepted: 07/23/2022] [Indexed: 11/05/2022]
Abstract
BACKGROUND AND AIM Multiple sclerosis (MS) is a demyelinating neurodegenerative inflammatory disease affecting mainly young adults. Microgliosis-derived neuroinflammation represents a key hallmark in MS pathology and progression. Nebivolol (Neb) demonstrated antioxidant, anti-inflammatory and neuroprotective properties in several brain pathologies. This study was conducted to investigate the potential neuroprotective effect of Neb in the cuprizone (Cup) model of MS. METHODS C57Bl/6 mice were fed 0.2% Cup mixed into rodent chow for 5 weeks. Neb (5 and 10 mg/kg/day) was administered by oral gavage during the last 2 weeks. RESULTS Neb prevented Cup-induced weight loss and motor deficits as evidenced by increased latency to fall in the rotarod test and enhanced locomotor activity as compared to Cup-intoxicated mice. Neb reversed Cup-induced demyelination as confirmed by Luxol fast blue staining and myelin basic protein western blotting. Administration of Neb modulated microglial activation status by suppressing M1 markers (Iba-1, CD86, iNOS, NO and TNF-α) and increasing M2 markers (Arg-1 and IL-10) as compared to Cup-fed mice. Furthermore, Neb hindered NLRP3/caspase-1/IL-18 inflammatory cascade and alleviated oxidative stress by reducing lipid peroxidation, as well as increasing catalase and superoxide dismutase activities. CONCLUSION These findings suggest the potential neuroprotective effect of Neb in the Cup-induced model of MS in mice, at least partially by virtue of shifting microglia towards M2 phenotype, mitigation of NLRP3 inflammasome activation and alleviation of oxidative stress.

Abstract
BACKGROUND The potential protective properties of carvacrol (CRV), which possesses various biological and pharmacological properties, against lung toxicity caused by cadmium (Cd), a major environmental pollutant, were investigated in the present study. METHODS AND RESULTS In the study, rats were given 25 or 50 mg/kg CRV orally 30 min after administrating 25 mg/kg cadmium chloride for seven days. Subsequently, the levels of 8-OHdG, MMP-2, and MMP-9, as well as markers of oxidative stress, inflammation, and apoptosis, were analyzed in the lung tissue of the animals. The results revealed that CRV exhibited antioxidant characteristics and raised SOD, CAT, GPx, and CAT levels and decreased the MDA levels induced by Cd. It also suppressed proinflammatory cytokines by lowering the levels of CRV NF-κB and p38 MAPK, thus exerting an anti-inflammatory effect against Cd. It was found that the levels of Bax, Caspase-3, and cytochrome c increased by Cd were decreased by the application of CRV. CRV also showed an anti-apoptotic effect by increasing Bcl-2 levels. The levels of 8-OHdG, MMP2, and MMP9, which increased with Cd administration, were observed to reduce after treatment with CRV. CONCLUSIONS The results indicate that CRV has protective properties against Cd-induced lung toxicity.

Abstract
Cadmium (Cd) is a widespread environmental heavy metal pollutant that has high toxicity to human health. Cd accumulates in the liver and results in oxidative stress and inflammatory reactions. Melatonin (MT), a hormone exhibiting strong antioxidative properties, has been proved to have hepatoprotective effect against both acute and chronic liver injury. However, the molecular mechanism underlying MT's hepatoprotective effect against Cd-induced liver injury remain not fully understood. In this study, the potential protective effect of MT on Cd-induced hepatic injury was investigated. Adult male C57BL/6 mice were randomly divided into four groups: control, CdCl2, MT, and CdCl2 plus MT groups. Animals were daily treated with either CdCl2 (5 mg/kg) or MT (10 mg/kg) or both through intragastric administration for 30 consecutive days. Serum enzymatic analysis indicated that treatment mice with Cd significantly increased AST, ALT, LDH and ALP levels, by contrast, MT treatment resulted in significant decreases of AST, ALT, LDH and ALP levels in the serum of Cd treated mice. By biochemical analysis, it was found that MT treatment significantly increased the activities of SOD, GSH, GST, CAT and GR, while significantly decreased the contents of MDA in the liver tissue of Cd treated mice. Moreover, MT treatment also suppressed the Cd-induced inflammation by reducing the inflammatory mediators, including IL-1β, IL-6, TNF-α and iNOS. Furthermore, MT treatment ameliorated the Cd-induced histopathological variations of liver tissue, which was confirmed by the biochemical and molecular data. It is clear from the results of this study that MT exerts hepatoprotective effect by improving the redox state, suppressing inflammatory reaction and cell apoptosis as well as ameliorating the performance of liver tissue histopathology, which is eventually reflected by the improvement of liver function in mice.

Abstract
AIM Cadmium (Cd) is a toxic heavy metal that causes severe toxic effects on different tissues including liver and kidney. Therefore the research for alternatives to reduce the damage caused by Cd has substantial importance. This study was performed to examine the possible modulatory effects of carvacrol (CRV) against Cd-induced hepatorenal toxicities and the possible mechanisms underlying these effects. MATERIALS AND METHODS In the present study, 35 male Wistar rats were randomly divided into 5 groups. The rats were treated with Cd (25 mg/kg) and treated with CRV (25 and 50 mg/kg body weight) for 7 consecutive days. KEY FINDINGS CRV could modulate Cd-induced elevations of ALT, ALP, AST, urea, creatinine, MDA and enhance antioxidant enzymes' activities such as SOD, CAT, and GPx, and GSH's level. CRV also reversed the changes in levels of inflammatory biomarker and apoptotic genes that include NF-κB, Bcl-3, MAPK-14, iNOS, COX-2, MPO, PGE2, Bax, Bcl-2, P53, Caspase-9, Caspase-6 and Caspase-3 in both tissues. The levels of 8-OHdG in the Cd-induced liver and kidney tissues were modulated after CRV treatment. Furthermore, CRV treatment considerably lowered Cd, Na, Fe, and Zn content while increased K, Ca, Mg and Cu contents in both tissues as compared to the Cd-exposed rats. SIGNIFICANCE The results of the present study revealed that CRV supplementation could be a promising strategy to protect the liver and kidney tissues against Cd-induced oxidative damage, inflammation and apoptosis.

Abstract
Cadmium (Cd), an environmental pollutant, is evidenced to cause hepatotoxicity. In this study, the potential protective effect of caffeic acid phenethyl ester (CAPE) on cadmium-induced liver damage was investigated. Forty male mice were treated daily with either CdCl2 (1.5 mg/kg body weight (b.w.), gavage) or CAPE (10 μmol/kg b.w., gavage) or both for 4 weeks. CAPE administration significantly reduced Cd level and liver and body weight, and increased AST, ALT and ALP level. Moreover, CAPE prevented CdCl2-induced oxidative stress via PI3K/Akt/mTOR pathway and inhibited apoptosis by regulating apoptosis markers. CAPE also suppressed the CdCl2-induced inflammation by reducing the inflammatory mediators, including TNF-α, IL-6 and IL-1β. Furthermore, CAPE alleviated CdCl2-induced reduction of TLR4. It should be noted that this effect was achieved by targeting miR-182-5p, and CAPE improved miR-182-5p level. The improvement of the liver tissue histopathology by CAPE confirmed the biochemical data. These results show for the first time that miR-182-5p/TLR4 axis involved in CAPE's protection against CdCl2-induced hepatotoxicity, and may provide novel insights into the treatment of cadmium-related diseases.

Abstract
Gene therapy has become a revolution and its breakthrough is a corner stone in modern science. This treatment has rising advantages with limited negative aspects. Gene therapy is a therapeutic method in which, transfer of DNA to an individual to manipulate a defective gene is performed and to mitigate a disease which is not responding to pharmacological therapy. The gene therapy strategies are divided into two main categories such as direct in-vivo gene delivery of manipulated viral vector vehicle into the host and ex-vivo genetically engineered stem cells. In this review, we tried to cover all aspects of gene therapy studies; starting with the concept of gene, its treatment, gene delivery system and types, clinical trial either by vitro or In-Vivo -Clinical Trials and Clinical Intoxication of Gene Therapy. Therefore, the promise of successful treatment with gene therapy could positively affect millions of lives. The main aim of this review is to address the principles of gene therapy, various methods involved in the gene therapy, clinical applications and its merits and demerits.

Abstract
AIM Ovarian torsion is a common gynecological emergency of reproductive ages, occurring at rates of 2.7-7.4%. This study aimed to evaluate the antioxidant effects of Nebivolol (NEB) and histopathological changes in experimental ischemic (I) and ischemic-reperfusion (I/R) injury in rat ovaries. METHODS Forty-eight adult female rats were randomly separated into six groups as group 1 (control) receiving an oral saline solution for 3 days; group 2 (I) that underwent ischemia for 3 h with the application of atraumatic vascular clips; group 3 (I/R); group 4 (I + NEB) receiving 10 mg/kg NEB by oral gavage 30 min prior to the ischemia induction; group 5 (I/R + NEB) receiving 10 mg/kg NEB, and group 6 (control + NEB) receiving oral 10 mg/kg NEB for 3 days before ischemia induction followed by consequent reperfusion. Ovarian tissue damage was scored by histopathological analysis. Ovarian tissue malondialdehyde (MDA) and glutathione (GSH) levels were measured biochemically. RESULTS The levels of MDA and tumor necrosis factor-alpha (TNF-α), and TUNEL assay positivity scores increased in the I and I/R groups. GSH levels decreased in all case groups (P < 0.05). The oral administration of NEB (10 mg/kg) to the I- and I/R-groups reduced the levels of MDA and TNF-α and TUNEL assay immunopositivity scores (P < 0.05). GSH levels increased in the treatment groups. CONCLUSION The current experimental ovarian torsion study suggests a protective role for NEB against I and I/R injury in rat ovaries. NEB may be a novel agent for decreasing ovarian I/R injury.

Abstract
The overexpression of inducible nitric oxide synthase (iNOS) induces cell apoptosis through various signal transduction pathways and aggravates lung injury. Caspase‑3 is an important protein in the apoptotic pathway and its activation can exacerbate apoptosis. Simvastatin, a hydroxymethyl glutaryl‑A reductase inhibitor, protects against smoke inhalation injury by inhibiting the synthesis and release of inflammatory factors and decreasing cell apoptosis. Following the establishment of an animal model of smoke inhalation injury, lung tissue and serum were collected at different time points and the protein and mRNA expression of iNOS and caspase‑3 in lung tissue by immunochemistry, western blot and reverse transcription‑quantitative polymerase chain reaction, the malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in lung tissue and serum were analyzed using thiobarbituric acid method and the WST‑1 method. The results were statistically analyzed. The lung tissues of the rats in the saline group and the low‑, middle‑ and high‑dose groups exhibited clear edema and hemorrhage, and had significantly higher pathological scores at the various time points compared with the rats in the control group (P<0.05). Furthermore, lung tissue and serum samples obtained from these four groups had significantly higher mRNA and protein expression levels of iNOS and caspase‑3 (P<0.05), significantly lower SOD activity and higher MDA content (P<0.05). Compared with the saline group, the low‑, middle‑ and high‑dose groups had significantly lower pathological scores (P<0.05), significantly lower mRNA and protein expression levels of iNOS, caspase‑3 and MDA content in lung tissues (P<0.05) and significantly higher SOD activity in lung tissues and serum. The middle‑ and high‑dose groups had significantly lower pathological scores (P<0.05), significantly decreased iNOS and caspase‑3 mRNA and protein expression in lung tissues, significantly higher SOD activity in lung tissues and serum and a significantly lower MDA content (P<0.05) compared with the low‑dose group. With the exception of SOD activity in lung tissues at 24 and 72 h and MDA content in serum at 48 h, no significant differences were observed between the middle‑ and high‑dose groups. The present study demonstrated that there was an association between the therapeutic effect and dosage of simvastatin within a definitive range. In rats with smoke inhalation injury, simvastatin inhibited iNOS and caspase‑3 expression in lung tissues and mitigated oxidative stress, thereby exerting a protective effect. In addition, the effect and dose were associated within a definitive range.

Abstract
The environmental pollution caused by cigarette smoke (CS) seriously endangers people's health. Epigallocatechin-3-gallate (EGCG) is the most abundant catechin in green tea. In this study, rats were exposed to CS for 90 days. Kidney function was evaluated by detecting the levels of serum creatinine and blood urea nitrogen. Liver function was evaluated by detecting the activities of alanine aminotransferase and aspartate transaminase. The renal and hepatic oxidative stress and inflammation were assessed by detecting the levels of malondialdehyde, reduced glutathione, antioxidant enzymes (superoxide dismutase and glutathione peroxidase) and proinflammatory cytokines. Organ fibrosis was evaluated by observing collagen deposition via masson staining, by examining the hydroxyproline level, by measuring the mRNA levels of fibrosis-associated genes collagen (Col)-1A1 and Col-3A1, as well as by assessing the activity of profibrotic TGF-β1 pathway. Additionally, renal and hepatic epithelial-mesenchymal transition (EMT) were evaluated. It was observed that EGCG ameliorated the renal and hepatic oxidative stress, inflammation, EMT, as well as inhibited the activation of TGF-β1 signaling pathway induced by CS. These results showed that EGCG could attenuate CS-induced renal and hepatic fibrosis.

Abstract
Senna alexandrina is traditionally used for its antioxidant and anti-inflammatory properties, but little information is available concerning its potential protective effects against cadmium, which is a widespread environmental toxicant that causes hepatotoxicity. Here, we explored the effects of S. alexandrina extract (SAE) on cadmium chloride (CdCl2)-induced liver toxicity over 4 weeks in rats. Rats were allocated into four groups: control, SAE (100 mg/kg), CdCl2 (0.6 mg/kg), and SAE + CdCl2, respectively. Cadmium level in hepatic tissue, blood transaminases, and total bilirubin as indicators of liver function were assessed. Oxidative stress indices [malondialdehyde (MDA), nitrate/nitrite (NO), and glutathione (GSH)], antioxidant molecules [superoxide dismutase (SOD, catalase (CAT), glutathione-derived enzymes, and nuclear factor erythroid 2-related factor 2 (Nrf2)], pro-inflammatory mediators [interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α)], apoptosis proteins (Bcl-2, Bax, and caspase-3), and histological alterations to the liver were examined. SAE administration before CdCl2 exposure decreased cadmium deposition in liver tissue and the blood liver function indicators. SAE pre-treatment prevented oxidative, inflammatory, and apoptotic reactions and decreased histological alterations to the liver caused by CdCl2 exposure. SAE can be used as a promising protective agent against CdCl2-induced hepatotoxicity by increasing Nrf2 expression. Graphical abstract.

Abstract
A wide range of contaminants, industrial by-products, plastics, and pharmaceutics belonging to various categories, have been found in sea water. Although these compounds are detected at concentrations that might be considered as sub-lethal, under certain conditions they could act synergistically producing unexpected effects in term of toxicity or perturbation of biochemical markers leading to standard pathway. In this study, the Sparus aurata fibroblast cell line SAF-1, was exposed to increasing concentrations of carbamazepine (CBZ), polybrominated diphenyl ether 47 (BDE-47) and cadmium chloride (CdCl2) until 72 h, to evaluate the cytotoxicity and the expression of genes related to antioxidant defense, cell cycle and energetic balance. In general, both vitality and gene expression were affected by the exposure to the different toxicants, in terms of antioxidant defense and cell cycle control, showing the most significant effects in cells exposed to the mixture of the three compounds, respect to the single compounds separately. The synergic effect of the compounds on the analyzed biomarkers, underlie the potential negative impact of the contaminants on health of marine organisms.

Abstract
Cadmium (Cd) is a highly toxic heavy metal with several harmful effects including cardiotoxicity. For the first time, we aimed to evaluate the possible cardioprotective effect of carvedilol (CAR) in Cd induced cardiotoxicity and study the mechanisms involved in such protection including endothelial nitric oxide synthase (eNOS) and HO1/Nrf2 pathway. CAR (1,10 mg/kg/d) was administered orally for 4 weeks with Cd induced cardiac injury (3 mg/kg/d) orally for 4 weeks. We measured cardiac enzymes, mean arterial pressure changes, heme oxygenase-1 (HO1) and total antioxidant capacity (TAC). Moreover; cardiac tissue malondialdehyde (MDA), tumor necrosis factor alpha (TNFα), western blotting of caspase3 and eNOS levels and histopathology were evaluated. Immunoexpression of eNOS in cardiac tissue, gene expression changes of HO1, and nuclear factor erythroid 2-related factor 2 (Nrf2) using real time polymerase chain reactions (rtPCR) were detected. Our results showed that CAR could significantly decrease Cd induced cardiotoxicity.

Abstract
The adverse health consequences of environmental, occupational, and dietary exposure to either diethylnitrosamine (DEN) or cadmium (Cd) have been widely investigated. However, because most environmental exposures to xenobiotics do not occur in isolation but in mixtures, the effects of simultaneous exposure to both DEN and Cd on hepatorenal function deserves investigation. The present study investigated the impact of 7 days oral co-exposure to 10 mg/kg body weight (b.w.) of DEN and 5 mg/kg b.w. of Cd on biomarkers of hepatic and renal functions, antioxidant defense systems, and oxidative stress indices in the liver and kidney of prepubertal rats. The results showed that the significant ( p < 0.05) increases in the levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma glutamyl transferase, urea, and creatinine following separate administration of DEN and Cd to rats were further increased in the co-exposure group. Moreover, marked decreases in the activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione-S-transferase as well as glutathione levels following individual administration of DEN and Cd to rats were exacerbated in the co-exposure group. Further, the marked increase in the lipid peroxidation level and the histopathological lesions in the liver and kidney of rats treated with DEN or Cd alone were intensified in the co-exposure group These findings indicate that co-exposure to DEN and Cd elicited more severe hepatic and renal oxidative damage in the rats, thus suggesting a greater risk to humans who are co-exposed to them.

Abstract
The aim of this study was to investigate effect of nitric oxide (NO) modulation on possible nephroprotective mechanisms of nebivolol (NEB) in cyclosporine A (CsA)-induced nephrotoxicity. Rats were treated with 20 mg/kg/day s.c. of CsA for 21 days, with NEB alone (10 mg/kg/day orally) or together with a NOS inhibitor, L-NAME (10 mg/kg/day i.p.). NEB conferred nephroprotection against CsA-induced toxicity, significantly decreasing serum kidney function tests and improving renal histopathology. NEB showed antioxidant effects, by significantly decreasing renal malondialdehyde levels, while increasing reduced glutathione levels and catalase activity. NEB showed anti-inflammatory and anti-apoptotic effects; reducing renal expression NF-κB and fas ligand. NEB also reversed CsA-induced effects on NO system; increasing renal NO level, with up-regulation of eNOS and down-regulation of iNOS expression. Administering L-NAME with NEB reversed all beneficial effects of NEB. Thus, NEB's modulation of NO system in CsA-induced nephrotoxicity might be the triggering mechanism controlling NEB's nephroprotective effect.

Abstract
Cadmium (Cd) is a common heavy metal contamination that is highly toxic to liver. Puerarin (PU), a potent free radical scavenger, has been shown to exert cytoprotective effect in numerous pathological processes. However, whether PU affords protection against Cd-induced hepatotoxicity remains unclear to be known. Here, we aimed to investigate the protective effect of PU on Cd-induced hepatotoxicity in an immortalized mouse hepatocyte line, AML-12. First, Cd-induced cytotoxicity in AML-12 cells was obviously ameliorated by PU treatment. Also, Cd-induced apoptotic cell death was markedly alleviated by PU treatment, evidenced by two methods. Simultaneously, Cd-elevated malondialdehyde and reactive oxygen species levels were significantly reduced by PU administration, demonstrating the antioxidant effect of PU against Cd exposure. Moreover, Cd-induced blockage of autophagic flux in AML-12 cells was obviously restored by PU treatment, evidenced by immunoblot analysis of autophagy marker proteins and tandem fluorescent-tagged LC3 method. Resultantly, Cd-induced autophagosome accumulation was significantly alleviated by PU treatment. In conclusion, these observations demonstrate that PU treatment alleviates Cd-induced hepatic cell damage by inhibiting apoptosis and restoring autophagy activity, which is intimately related with its antioxidant activity.

Abstract
The study investigated, in a rat model of low-level and moderate environmental exposure to cadmium (Cd; 1 or 5 mg Cd/kg diet, respectively, for 3 to 24 months), whether the co-administration of 0.1% extract from Aronia melanocarpa L. berries (AE) may protect against oxidative stress in the liver and in this way mediate this organ status. The intoxication with Cd, dose- and duration-dependently, weakened the enzymatic antioxidative barrier, decreased the concentrations of reduced glutathione and total thiol groups, and increased the concentrations of oxidized glutathione, hydrogen peroxide, xanthine oxidase, and myeloperoxidase in this organ. These resulted in a decrease in the total antioxidative status, increase in the total oxidative status and development of oxidative stress (increased oxidative stress index and malondialdehyde concentration) and histopathological changes in the liver. The administration of AE at both levels of Cd treatment significantly improved the enzymatic and nonenzymatic antioxidative barrier, decreased pro-oxidant concentration, and protected from the development of oxidative stress in the liver and changes in its morphology, as well as normalized the serum activities of liver enzymes markers. In conclusion, consumption of aronia products may prevent Cd-induced destroying the oxidative/antioxidative balance and development of oxidative stress in the liver protecting against this organ damage.
