Effects of Moringa oleifera Leaf Extract on Diabetes-Induced Alterations in Paraoxonase 1 and Catalase in Rats Analyzed through Progress Kinetic and Blind Docking. Antioxidants (Basel) 2020; 9:antiox9090840. [PMID: 32911700 PMCID: PMC7555439 DOI: 10.3390/antiox9090840] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Revised: 08/18/2020] [Accepted: 09/03/2020] [Indexed: 02/07/2023] Open
Abstract
In our study, we aimed to evaluate the effects of Moringa oleifera leaves extract on rat paraoxonase 1 (rPON1) and catalase (rCAT) activities in alloxan-induced diabetic rats. Our study included three groups; group C (control, n = 5); group D (diabetic, n = 5); and group DM (M. oleifera extract-supplemented diabetic rats, n = 5). Daily oral administration of M. oleifera extract at 200 mg/kg doses produced an increase in endogenous antioxidants. Serum rPON1 (lactonase) and liver cytosol catalase activities were determined by a spectrophotometric assay using progress curve analysis. We found a decrease in the Vm value of rPON1 in diabetic rats, but dihydrocoumarin (DHC) affinity (Km) was slightly increased. The value of Vm for the DM group was found to be reduced approximately by a factor of 3 compared with those obtained for group C, whereas Km was largely changed (96 times). Catalase activity was significantly higher in the DM group. These data suggest that the activation of rPON1 and rCAT activities by M. oleifera extracts may be mediated via the effect of the specific flavonoids on the enzyme structure. In addition, through molecular blind docking analysis, rPON1 was found to have two binding sites for flavonoids. In contrast, flavonoids bound at four sites in rCAT. In conclusion, the data suggest that compounds from M. oleifera leaves extract were able to influence the catalytic activities of both enzymes to compensate for the changes provoked by diabetes in rats.

Abstract
Backgrounds Melatonin has significant antioxidant and hepatoprotective effects in normal and oxidative stress conditions. The aim of the present study was to assess the effects of melatonin on antioxidant, hepatic, and renal factors in intact and castrated dogs. Twenty male mixed-breed adult dogs were aligned in an experimental randomized and controlled trial. The dogs were randomly divided into four equal groups: melatonin, castrated, castrated and melatonin, and control. They were treated with melatonin (0.3 mg/Kg, once daily, orally) immediately after the castration for 1 month and their blood samples were collected weekly from 2 days after treatment with melatonin. Results Treating castrated dogs with melatonin increased the level of glutathione peroxidase, superoxide dismutase, and catalase compared with that of the control and castrated groups. The malondialdehyde level increased significantly following castration. Melatonin treatment decreased malondialdehyde concentration in the castrated dogs. Castration increased the level of alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase significantly in comparison with that of the control group. Treating the castrated dogs with melatonin decreased significantly liver enzymes compared with those of the castrated dogs. Blood urea nitrogen and creatinine levels increased in the castrated dogs in comparison with that of the control group. Conclusions The administration of melatonin in castrated dogs increased antioxidant activity and decreased oxidation products, compared with those of the castrated and untreated dogs, without adverse effects on liver enzymes and kidney function.

Abstract
Perfluorooctanoic acid (PFA) has been identified as an environmental contaminant of high concern for human health. In this study, we demonstrated that PFA induces a dose (0 to 1.5 mM) dependent cytotoxicity in S. cerevisiae cells which can be rescued by astaxanthin. The percent sensitivity induced by PFA and the cell protection offered by astaxanthin (30 μM) were demonstrated by CFU counts and spots. The increase in intracellular ROS, superoxide dismutase (SOD), glutathione and lipid peroxidation levels in PFA treated cells suggested that increased oxidative stress resulted in yeast cell death. In contrast, decreased ROS level, increased SOD activity, reduced glutathione and decreased lipid peroxidation by astaxanthin supplementation suggest that the cells are protected from the PFA induced oxidative stress mediated cytotoxicity. Reduced chromatin condensation and nuclear fragmentation in astaxanthin pre-treated cells indicate that astaxanthin rescued the cells from PFA induced apoptosis. Our overall results suggest that PFA induces oxidative stress-mediated cytotoxicity in yeast cells, which were rescued by astaxanthin treatment.

Abstract
Oxidative stress is part of the mechanisms involved in ethanol toxicity. We investigated effects of vitamins C (VC), E (VE) and the combination of VC+VE on chronic ethanol-induced toxicity in rat erythrocytes. The following groups were treated for 30 days: control (C), VC (200 mg/kg), VE (200 mg/kg), VC (200 mg/kg) + VE (200 mg/kg), ethanol 4 g/kg, ethanol + VC, ethanol + VE and ethanol + VC + VE. The doses of vitamins and ethanol were selected for per kilogram of animal's body weight. Blood samples collected at the end of treatments were analyzed for erythrocyte osmotic fragility and plasma scavenging activity. The washed erythrocytes were used to determine superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and malondialdeyde (MDA). Ethanol induced erythrocyte fragility (p < 0.001) and increased lipid peroxidation (p < 0.001) in rat erythrocytes. Furthermore, there were significant decreases in plasma scavenging (p < 0.001), SOD (p < 0.001), CAT (p < 0.01) and GPx (p < 0.001) activities in erythrocytes of ethanol-treated animals. Although VC or VE alone restored all of ethanol-induced disturbances to near normal (p > 0.05) but there were still significant differences compared to control animals. Combination therapy completely corrected ethanol-induced erythrocyte fragility, lipid peroxidation and prooxidant/antioxidant imbalance. We showed the beneficial effects of VC and VE combination in decreasing erythrocyte fragility and lipid peroxidation in both ethanol and control groups. Therefore this combination treatment may provide a new potential alternative for prevention of ethanol toxicity which deserves consideration and further examination.

Abstract
Oxidative stress and increased production of reactive oxygen species have been implicated in pesticides and heavy metals toxicity. The objective of this study was to investigate the efficacy of Turnera diffusa Willd (damiana) on counteracting fenitrothion (FNT) and/or potassium dichromate (CrVI)-induced testicular toxicity and oxidative injury in rats. FNT and/or CrVI intoxicated animals revealed a significant increase in thiobarbituric acid reactive substances and hydrogen peroxide levels. While, reduced glutathione and protein content, as well as antioxidant enzymes, phosphatases, and aminotransferases activities, were significantly decreased. In addition, significant changes in testosterone and follicle-stimulating hormone levels were detected. Furthermore, histological and immunohistochemical alterations were observed in rat testes and this supported the observed biochemical changes. On the other hand, rats treated with damiana alone decreased lipid peroxidation and increased most of the examined parameters. Moreover, damiana pretreatment to FNT and/or CrVI-intoxicated rats showed significant improvement in lipid peroxidation, enzyme activities, and hormones as compared with their respective treated groups. Conclusively, rats treated with both FNT and/or CrVI showed pronounced hazardous effect especially in their combination group in addition, Turnera diffusa had a potential protective role against FNT and/or CrVI induced testicular toxicity.

Abstract
The ubiquitous use of diazinon (DZN, an organophosphorus insecticide) has increased the probability of occupational, public, and the ecosystem exposure; these exposures are linked to negative health outcomes. The flavonoids curcumin (CUR) and quercetin (QUE) exert significant anti-inflammatory and antioxidant activities against toxicants, including insecticides. However, it is unclear whether their combination enhances these activities. Therefore, 40 albino rat were divided randomly into the CTR, DZN, CUR + DZN, QUE + DZN, and CUR + QUE + DZN groups, which are treated daily via gavage for 28 days. DZN induced neurohepatic inflammation and oxidative damage, which was confirmed by significant (P < 0.05) induction of aspartate and alanine aminotransferases, alkaline phosphatase, lactate dehydrogenase, γ-glutamyl transferase, and tumor necrosis factor-α and inhibition of acetylcholinesterase activity. Furthermore, the liver and brain of DZN-exposed rats exhibited a notable elevation in MDA level paralleled with reduction in antioxidant molecules, i.e., glutathione, superoxide dismutase, glutathione peroxidase, and catalase. The pretreatment of DZN-intoxicated rats with CUR or QUE substantially mitigated neurohepatic dysfunction and inflammation and improved liver and brain antioxidant status with reducing oxidative stress levels. Furthermore, pretreatment with CUR + QUE synergistically restored the neurohepatic dysfunction and oxidative levels to approximately normal levels. The overall results suggested that CUR or QUE inhibits DZN-mediated neurohepatic toxicity via their favorable anti-inflammatory, antioxidant, and free radical-scavenging activities. Moreover, both QUE and CUR may be mutual adjuvant agents against oxidative stress neurohepatic damages.

Abstract
Organophosphorus pesticides form a diverse group of chemicals, having a wide range of physicochemical properties with crucial toxicological actions and endpoints. These are extensively used to control pests of different food (fruits, vegetables, tea, etc.) and non-food (tobacco, cotton, etc.) crops. Malathion is an important widely used organophosphorus pesticide but its hepatotoxic effects on fish are not well studied. Therefore, the current study was designed to investigate the hepatotoxic effects of Malathion on rohu (Labeo rohita) fish in a semi-static system using different parameters. The LC50 of Malathion was found to be 5 µg/L for rohu for 96 h through Probit analysis and was used for further toxicity testing. To find the hepatotoxic effects of Malathion, changes in different biochemical indices including protein contents, Lipid Peroxidation (LPO), activities of four protein metabolic enzymes [Aspartate Aminotransferase (AAT), Lactate Dehydrogenase (LDH), Alanine Aminotransferase (AlAT), and Glutamate Dehydrogenase (GDH)], seven antioxidant enzymes [Catalase (CAT), Superoxide Dismutase (SOD), Peroxidase (POD), Glutathione (GSH), Glutathione Reductase (GR), Glutathione-s-transferase (GST), and Glutathione Peroxidase (GSH-Px)], DNA damage [in term of comet tail length, tail moment, DNA percentage in tail, and olive tail moment], reactive oxygen species (ROS), and Histopathological alterations were assayed. Malathion exposure led to a time-reliant significant (P < 0.05) decrease in protein contents and a significant (P < 0.05) increase in ROS, LPO, enzymatic activities, and DNA damage. The histopathological examination of the liver showed different changes including hepatic necrosis, fatty infiltration, hemorrhage vacuolation, glycogen vacuolation, congestion, and cellular swelling. The current study clearly revealed Malathion as a potent hepatotoxic pesticide; therefore the injudicious, indiscriminate and extensive use of Malathion should be prohibited or at least reduced and strictly monitored.

Abstract
This study was conducted to evaluate the protective effects of Sardinella pilchardis oil and vitamin E against chlorpyrifos- (CPF-) induced liver, kidney, and brain oxidative damage in female rats. The rats were divided into 6 experimental groups: the control group, the group treated with fish oil, the group that received fish oil for 2 weeks and CPF orally for 7 days, the group treated only with CPF, the group treated with vitamin E for 2 weeks and CPF for 7 days, and the group treated with vitamin E. Oral exposure to CPF induced a significant increase in serum biochemical parameters; hepatic, kidney, and brain LPO; and a decrease in superoxide dismutase, catalase, and glutathione peroxidase activities. Fish oil or vitamin E decreased significantly the mentioned biochemical parameters as compared to rats treated with CPF alone. This study suggests that fish oil has an ameliorative effect for the alleviation of the oxidative damage induced by CPF.

Abstract
AIM Oxidative stress is an important component of the mechanism of pesticide toxicity. The aim of the present study was to investigate the time-dependent melatonin effects against abamectin-induced oxidative stress in a S.litura model. Larvae were divided into 5 different groups; (1) control group,(2) Melatonin group (4.3×10-5M/100ml diet), (3) Abamectin group 1.5ml/L, (4) Pre-melatonin treated group (PM) (4.3×10-5M/100ml diet) before abamectin exposure 1.5ml/L, (5) Post-melatonin treated group (TM) after abamectin exposure. Melatonin was supplemented via artificial diet in PM and TM animals during 24h. MAIN METHODS Midgut, fatbody, and hemolymph, were collected for the analysis of oxidative stress markers (Total ROS, GSH, nitrite, TBARS, LPO), antioxidant enzyme levels (SOD, GST, CAT, POX, APOX) in fifth instar larvae. Midgut damage was examined by using morphological analysis. KEY FINDINGS Our results observed that ABA group showed significant changes (p<0.001) in the ROS and carbonyl content in midgut. The increase of antioxidant enzyme levels (SOD, CAT, POX, and APOX) in midgut was led by the continuous free radical scavenger cascade of melatonin. Significant (p<0.01) increases in CAT and APOX levels were seen in the fatbody of PM and TM treated insects. SIGNIFICANCE In conclusion, the results of the study revealed that abamectin toxicity generates oxidative stress in the insect, while pre-melatonin treatment reduces this damage due to its antioxidant properties, especially POX levels in midgut, fatbody, and hemolymph. Therefore, indoleamine can play a vital role curtailing the abamectin toxicity in time dependent manner in S.litura.

Abstract
This study investigated the morphological, biochemical and molecular aspects of liver injury in rats after the exposure to difenoconazole and the protective effects of quercetin against hepatotoxicity and genotoxicity induced by this fungicide. Rats were given graded doses of difenoconazole associated or not to quercetin daily for 20 days. Our results showed a significant increase in PLT (platelets) and WBC (white blood cells) in rats treated with higher doses of difenoconazole (1/38 and 1/9 of LD50). However, a significant decrease in Hb (hemoglobin) rate and RBC (red blood cells) number in rats treated with higher doses of difenoconazole (1/38 and 1/9 of LD50) was obtained. Besides, difenoconazole treatment caused an increase in hepatic enzyme activities of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH). Difenoconazole increased the levels of malondialdehyde (MDA) and advanced oxidation protein products (AOPPs), and decreased superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) activities and vitamin C levels in liver tissues compared to the control group. We also noted a degradation of nucleic acids, testifying difenoconazole genotoxicity. Changes in hepatic tissues were confirmed by histological findings. Co-administration of quercetin (20 mg/kg) improved hematological and biochemical parameters and showed a significant liver protective effect by decreasing MDA levels and producing advanced oxidation protein, along with increased antioxidative enzyme activities and vitamin C levels. Results were confirmed by the improvement of histological impairments. Thus, it appears that quercetin was effective in preventing acute liver injury induced by exposure to difenoconazole.

Abstract
Agricultural workers are exposed to many contaminants and suffer from respiratory and other symptoms. Dusts, gases, microbial products and pesticide residues from farms have been linked to effects on the health of agricultural workers. Growing sets of data from in vitro and in vivo models demonstrate the role of the innate immune system, especially Toll-like receptor 4 (TLR4) and TLR9, in lung inflammation induced following exposure to contaminants in agricultural environments. Interestingly, inflammation and lung function changes appear to be discordant indicating the complexity of inflammatory responses to exposures. Whereas the recent development of rodent models and exposure systems have yielded valuable data, we need new systems to examine the combined effects of multiple contaminants in order to increase our understanding of farm-exposure-induced negative health effects.

Abstract
Background: Chlorpyrifos (CP) is an organophosphorus pesticide that induces oxidative stress through the production of free radicals and depletes intracellular antioxidant reserves. In this study, the efficacy of three antioxidants (melatonin, coenzyme Q10 (CoQ10), and vinpocetine) on alleviation of toxic effects of CP was evaluated. Materials and Methods: Cytotoxicity of CP, in the presence or absence of effective doses of melatonin, CoQ10, and vinpocetine, was determined in human peripheral blood lymphocytes after 72-h exposure. The levels of acetylcholinesterase (AChE) activity along with tumor necrosis factor α (TNF-α), as inflammatory index, were measured. Further, the viability and oxidative stress markers including cellular mitochondrial activity, cell death modes (apoptosis vs. necrosis), total antioxidant power (TAP), total thiol molecules (TTM), lipid peroxidation (LPO), and myeloperoxidase (MPO) activity were measured. Results: CoQ10 and also the combination of the three antioxidants were the most notable in opposing toxicity of CP and led to increasing TAP and TTM; improvement of AChE activity; and lowering LPO, MPO, TNF-α, and apoptosis compared to CP alone. Conclusion: CP toxicity overwhelms the intracellular antioxidant defense mechanisms. Exogenous supplementation with antioxidants, such as the ones we have investigated, seems to be effective in the prevention of cytotoxicity of CP.

Abstract
The imidacloprid is used worldwide as a pesticide and has been linked with endocrine disturbances and reduced pulmonary function. However, effects of imidacloprid alone or in combination with microbial molecules on lungs are not fully understood. Because the pulmonary effects of interactions of endotoxins with imidacloprid are unknown, we designed a study to investigate that in a mouse model. Mice (N=14) were given imidacloprid orally @ 1/20(th) of LD50 dissolved in corn oil for 30days. After the treatments, six animals from each group were challenged with E. coli lipopolysaccharide (LPS) @ 80μg/animal via intranasal route and remaining animals were challenged with normal saline solution @ 80μl/animal via same route. Imidacloprid in combination with LPS led to significant increase in total cell and neutrophil counts in BAL and peripheral blood. Semi-quantitative histopathology revealed lung injury in imidacloprid treatment group and injury was more marked in animal receiving both imidacloprid and LPS. There was no change (p<0.05) in the expression of TLR-4 and TNF-α both at mRNA and protein levels following exposure to imidacloprid alone or in combination with LPS. The data show that imidacloprid alone or in combination with LPS resulted changes in lung morphology without altering the expression of TLR-4 and TNF-α. Furthermore, pre-treatment with imidacloprid didn't affect response to LPS.

Abstract
Metals are ubiquitously present in the environment and pesticides are widely used throughout the world. Environmental and occupational exposure to metal along with pesticide is an area of great concern to both the public and regulatory authorities. Our major concern is that combination of these toxicant present in environment may elicit toxicity either due to additive or synergistic interactions or 'joint toxic actions' among these toxicants. It poses a rising threat to human health. Water contamination particularly ground water contamination with arsenic is a serious problem in today's scenario since arsenic is associated with several kinds of health problems, such arsenic associated health anomalies are commonly called as 'Arsenism'. Uncontrolled use and spillage of pesticides into the environment has resulted in alarming situation. Moreover serious concerns are being addressed due to their persistence in the environmental matrices such as air, soil and surface water runoff resulting in continuous exposure of these harmful chemicals to human beings and animals. Bio-availability of these environmental toxicants has been enhanced much due to anthropological activities. Dreadfully very few studies are available on combined exposures to these toxicants on the animal or human system. Studies on the acute and chronic exposure to arsenic and DDVP are well reported and well defined. Arsenic is a common global ground water contaminant while dichlorvos is one of the most commonly and widely employed organophosphate based insecticide used in agriculture, horticulture etc. There is thus a real situation where a human may get exposed to these toxicants while working in a field. This review highlights the individual and combined exposure to arsenic and dichlorvos on health.

Abstract
The present study was designed to assess the possible protective effects of Quercetin (QUER), a flavonoid with well-known pharmacological effects, against Dichlorvos (DDVP)-induced toxicity in vitro using HCT116 cells. The cytotoxicity was monitored by cell viability, reactive oxygen species (ROS) generation, anti-oxidant enzyme activities, malondialdehyde (MDA) production, and DNA fragmentation. The apoptosis was assessed through the measurement of the mitochondrial transmembrane potential (ΔΨm) and caspase activation. The results indicated that pretreatment of HCT116 cells with QUER, 2 h prior to DDVP exposure, significantly decreased the DDVP-induced cell death, inhibited the ROS generation, modulated the activities of catalase (CAT) and superoxide dismutase (SOD), and reduced the MDA level. The reductions in mitochondrial membrane potential, DNA fragmentation, and caspase activation were also attenuated by QUER. These findings suggest that dietary QUER can protect HCT116 cells against DDVP-induced oxidative stress and apoptosis.

Abstract
OBJECTIVE Chlorpyrifos (CP) as an organophosphorus pesticide is thought to induce oxidative stress in human cells via producing reactive oxygen species (ROS) that leads to the presence of pathologic conditions due to apoptosis along with acetylcholinesterase (AChE) inhibition.This study aimed to evaluate the apoptotic effects of CP and to assess the protective potential of CeO2nanoparticle (CNP) and sodium selenite (SSe) by measuring cascades of apoptosis, oxidative stress, inflammation, and AChE inhibition in human isolated lymphocytes. MATERIALS AND METHODS In the present experimental study, we examined the anti-oxidative and AChE activating potential of CNP and SSe in CP-treated human lymphocytes. Therefore, the lymphocytes were isolated and exposed to CP, CP+CNP, CP+SSe, and CP+CNP+SSe after a three-day incubation. Then tumor necrosis factor-alpha (TNF-α) release, myeloperoxidase (MPO) activity, thiobarbituric acid-reactive substances (TBARS) levels as inflammatory/oxidative stress indices along with AChE activity were assessed. In addition, the apoptotic process was measured by flow cytometry. RESULTS Results showed a significant reduction in the mortality rate, TNF-α, MPO activity, TBARS, and apoptosis rate in cells treated with CNP, SSe and their combination. Interestingly, both CNP and SSe were able to activate AChE which is inhibited by CP. The results supported the synergistic effect of CNP/SSe combination in the prevention of apoptosis along with oxidative stress and inflammatory cascade. CONCLUSION CP induces apoptosis in isolated human lymphocytes via oxidative stress and inflammatory mediators. CP firstly produces ROS, which leads to membrane phospholipid damage. The beneficial effects of CNP and SSe in reduction of CP-induced apoptosis and restoring AChE inhibition relate to their anti-oxidative potentials.

Abstract
AIM To examine the possible protective effect of Satureja khuzistanica essential oil (SKE) on antioxidant enzyme activity in alloxan-induced Type 1 diabetic rats. METHOD Thirty Sprague-Dawley male rats were divided into three groups randomly; group one as control, group two diabetic, with no treatment, and group three treatment with SKE at 500 ppm in drinking water, respectively. Diabetes was induced in the second and third groups by alloxan injection subcutaneously. After eight weeks, animals were anaesthetized. Blood samples were also collected before killing to measure antioxidant enzymes activity. RESULTS SKE significantly increased the serum level of glutathione and the serum activity of glutathione peroxidase, superoxide dismutase, and catalase in the treated group compared with the diabetic untreated group. CONCLUSION The findings showed that SKE exerts beneficial effects on the antioxidant enzymes activity in alloxan-induced Type 1 diabetic rats.

Abstract
Previous studies showed that the spatial cognitive deficits of rats were induced by chronic melamine exposure, which was associated with the hippocampal oxidative damage. Currently, we examined the antioxidative effect of vitamins C and E combination on cognitive function in melamine-treated rats. Melamine was oral administrated to male adolescent Wistar at a dosage of 300mg/kg/day for 28days. After that, animals received vitamins C and E at a dose of 150 and 200mg/kg, respectively, intraperitoneally for the next 7days. Cognitive behaviors were investigated using the Morris water maze test. The biochemical indexes were detected in the hippocampal homogenate. The treatment with vitamin complex significantly ameliorated cognitive deficits induced by melamine. ROS, MDA, and NO contents were almost back to normal, while SOD, CAT, GSH-Px, and NOS activities were improved as well. The neural apoptosis in the hippocampus were ameliorated by regulating the expression of anti-apoptotic protein (Bcl-2) and caspase-3. Additionally, histological observation showed that vitamin complex effectively alleviated the injuries of hippocampal neurons. These results suggest that the potential therapeutic for oxidative damage induced neuronal apoptosis after treatment of vitamins C and E combination, which is most likely related to the antioxidative effects.

Abstract
Pesticides are omnipresent in environment, water, fruits, and vegetables and are considered as risk factors for human health. Consumers are mainly exposed to pesticides through diet, and the main question to be answered concerns the impact of such exposure on health. In this study, we developed a mouse model to mimic consumer exposure. During gestation and lactation periods, the experimental mouse dams (M) received one of the following treatments: (a) diet-free of pesticides; (b) diet enriched with chlorpyrifos (CPF; 44.0 μg kg(-1)); c) diet + oral vitamin E (vit. E; α-tocopherol; 200 mg/kg/mouse); and (d) diet enriched with CPF (44.0 μg/kg + oral vit. E (200 mg/kg/mouse). At weaning, pups (P) and dams were killed, and organs as well as blood samples were collected. Compared with control results, CPF induced alteration of measured parameters (e.g. organ weight, alkaline phosphatase, urea, malondialdehyde, superoxide dismutase, and cholinesterase) either in mouse dams or in their offspring. Also, CPF induced histological impairment in kidney, liver, and ovary. Administration of vit. E in conjunction with CPF clearly alleviated deviation of these parameters than those of control ones. In conclusion, a dietary exposure of mice during gestation and lactation to low dose of CPF led to significant changes in the mother but also in the weaned animals that have not been directly exposed to this pesticide. These biological and histological modifications could be reversed by an oral supplementation of vit. E.

Abstract
Diazinon (DZN) is one of the most organophosphate insecticides that widely used in agriculture and industry. Selenium is generally recognized to be a trace mineral of great importance for human health, protecting the cells from the harmful effects of free radicals. Therefore, the present study was carried out to investigate the alterations in biochemical parameters, free radicals and enzyme activities induced by diazinon in male rat serum, and the role of selenium in alleviating the negative effects of DZN. Animals were divided into four groups of seven rats each; the first group was used as control. Groups 2, 3 and 4 were treated with selenium (Se; 200μg/kg BW), diazinon (DZN; 10mg/kg BW) and diazinon plus selenium, respectively. Rats were orally administered their respective doses daily for 30 days. Results obtained showed that DZN significantly induced thiobarbituric acid reactive substances (TBARS) and decreased the activities of glutathione S-transferase (GST), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GR) and the levels of reduced glutathione (GSH) in rat sera. Aminotransferases (AST, ALT), phosphatases (AlP, AcP) and lactate dehydrogenase (LDH) activities were significantly increased while acetylcholinesterase (AChE) activity was decreased due to DZN administration. Also, DZN treatment caused significant perturbations in lipids profile and serum biochemical parameters. On the other hand, Se alone significantly decreased the levels of TBARS, total lipids, cholesterol, urea and creatinine, while increased the activities of antioxidant enzymes and glutathione content, total protein (TP) and albumin. In addition, Se in combination with DZN partially or totally alleviated its toxic effects on the studied parameters. In conclusion, Se has beneficial effects and could be able to antagonize DZN toxicity.

Abstract
This study examined the effect of lethal (4.5 μg/l) and sublethal (0.45 μg/l) malathion levels on oxidative stress responses of the freshwater edible fish, Labeo rohita. Fish were exposed to lethal (1-4 days) and sublethal (1, 5, 10, and 15 days) periods. In the present study, catalase and protease activity, hydrogen peroxide, malondialdehyde, protein carbonyls, and free amino acids levels increased in the gill, liver, and kidney tissues of fish exposed to lethal and sublethal concentrations of malathion except protein content. Time- and concentration-dependent induction/reduction of the above parameters by lethal and sublethal concentrations of malathion was observed in the tissues (the gill, liver, and kidney) of L. rohita. Thus, the results clearly infer oxidative damage and decline in antioxidant defense due to malathion-induced oxidative stress.

Abstract
AbstractMelatonin is a hormone produced by the pineal gland. In addition to its hormonal effect, it has strong antioxidant properties. Melatonin is probably best known for its ability to control circadian rhythm; it is sold in many countries as a supplement or drug for improving of sleep quality. However, melatonin’s effect is not limited to control of circadian rhythm:. it is involved in other effects, including cell cycle control and regulation of several important enzymes, including inhibition of inducible nitric oxide synthase. Melatonin affects immunity as well. It can modulate the immune response on disparate levels with a significant effect on inflammation. The role of melatonin in body regulatory process is not well understood; only limited conclusions can be drawn from known data. The current review attempts to summarize both basic facts about melatonin’s effects and propose research on the lesser known issues in the future.

Abstract
Melatonin is a neurohormone secreted by the pineal gland. It is widely present in both plant and animal sources. In several countries, it is sold over the counter as tablets and as food supplement or additive. Currently, it is most often used to prevent jet lag and to induce sleep. It has been and is being used in several clinical trials with different therapeutic approaches. It has sedative, analgesic, anti-inflammatory, anti-oxidative and chronobiotic effects. In the present review, the potential therapeutic benefits of melatonin in anaesthesia and critical care are presented. This article aims to review the physiological properties of melatonin and how these could prove useful for several clinical applications in perioperative management, critical care and pain medicine. The topic was handsearched from textbooks and journals and electronically from PubMed, and Google scholar using text words.

Abstract
The joint action of pyrethroids, lambda-cyhalothrin (LC) in combination with organophosphates, fenitrothione (FNT) on antioxidant defense system and lipid peroxidation biomarkers in rat testes was studied. The results suggest that incubation of testes homogenate with different concentrations of insecticide mixture for different time intervals significantly decreased the activity of antioxidant enzymes, like glutathione S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT), and the level of reduced glutathione (GSH). In addition, a significant inhibition in transaminases (AST, ALT), phosphatases (AcP, AlP) activity and protein content were observed. On the other hand, FNT plus LC increased the cellular lipid peroxidation (LPO) level and the activity of lactate dehydrogenase (LDH). In conclusion, the use of insecticides mixture might cause marked oxidative damage in a concentration and time-dependent manner.

Abstract
Coenzyme Q10 is a natural antioxidant and scavenging free radicals. In the present study, we examined antioxidative activities of coenzyme Q10 and possible protective effect of coenzyme Q10 on in vivo and in vitro lipid peroxidation, antioxidant enzymes activity and glomerulosclerosis in alloxan-induced type 1 diabetic rats. Thirty Sprague-Dawley male rats were divided into three groups randomly: group 1 as control, group 2 as diabetic untreatment, and group 3 as treatments with coenzyme Q10 by 15 mg/kg i.p. daily, respectively. Diabetes was induced in the second and third groups by alloxan injection subcutaneously. After 8 weeks, animals were anaesthetized, liver and kidney were then removed immediately and used fresh or kept frozen until their lipid peroxidation analysis. Blood samples were also collected before killing to measure the lipid peroxidation and antioxidant enzymes activity. Kidney paraffin sections were prepared and stained by periodic acid-Schiff method. Glomerular volume and leukocyte infiltration were estimated by stereological rules and glomerular sclerosis was studied semi-quantitatively. Coenzyme Q10 significantly inhibited leukocyte infiltration, glomerulosclerosis and the levels of malondialdehyde (MDA) serum and kidney content in treated group compared with the diabetic untreated group. Coenzyme Q10 significantly inhibited LDL oxidation in vitro. Coenzyme Q10 significantly increased the serum levels of glutathione (GSH) and serum activity of catalase (CAT) and superoxide dismutase (SOD) in treated group compared with the diabetic untreated group. Coenzyme Q10 alleviates leukocyte infiltration and glomerulosclerosis and exerts beneficial effects on the lipid peroxidation and antioxidant enzymes activity in alloxan-induced type 1 diabetic rats.

Abstract
Reactive oxidative species (ROS) generated by environmental toxicants including pesticides could be one of the factors underlying the neuronal cell damage in neurodegenerative diseases. In this study we found that chlorpyrifos (CPF) induced apoptosis in dopaminergic neuronal components of PC12 cells as demonstrated by the activation of caspases and nuclear condensation. Furthermore, CPF also reduced the tyrosine hydroxylase-positive immunoreactivity in substantia nigra of the rat. In addition, CPF induced inhibition of mitochondrial complex I activity. Importantly, N-acetyl cysteine (NAC) treatment effectively blocked apoptosis via the caspase-9 and caspase-3 pathways while NAC attenuated the inhibition of mitochondrial complex I activity as well as the oxidative metabolism of dopamine (DA). These results demonstrated that CPF-induced apoptosis was involved in mitochondrial dysfunction through the production of ROS. In the response of cellular antioxidant systems to CPF, we found that CPF treatment increased HO-1 expression while the expression of CuZnSOD and MnSOD was reduced. In addition, we found that CPF treatment activated MAPK pathways, including ERK 1/2, the JNK, and the p38 MAP kinase in a time-dependent manner. NAC treatment abolished MAPK phosphorylation caused by CPF, indicating that ROS are upstream signals of MAPK. Interestingly, MAPK inhibitors abolished cytotoxicity and reduced ROS generation by CPF treatment. Our results demonstrate that CPF induced neuronal cell death in part through MAPK activation via ROS generation, suggesting its potential to generate oxidative stress via mitochondrial damage and its involvement in oxidative stress-related neurodegenerative disease.

Abstract
The present study was carried out to determine histopathological effects of nicotine, one of the most significant components of tobacco, on mouse liver and ameliorative effect of melatonin on liver damage. A total of 140 mature Swiss Albino mice ( Mus musculus) were divided into four experimental groups: control group, nicotine group, melatonin group and nicotine + melatonin group. Each group was further subdivided into seven groups (five mice each) according to the time of killing (12 h and days 1, 3, 5, 7, 14 and 21 after drug administration). In nicotine and nicotine + melatonin groups, 3 mg/kg of nicotine was injected intraperitoneally every day until killing. The nicotine + melatonin group was additionally injected with 10 mg/kg of melatonin after 30 min of nicotine injection. The melatonin group was injected only with 10 mg/kg of melatonin every day until killing. All the treatments were given 2 h before sunset, when melatonin receptors were active. After the last injection, five mice from each group were killed at 12th hour and on days 1, 3, 5, 7, 14 and 21; the livers were removed for histopathological processing by light microscopy. The histopathological results revealed time-dependent degeneration in the livers of mice in nicotine group. Regenerative changes in the nicotine and melatonin groups were observed when compared with nicotine groups.

Protective effects of catechin and quercetin on antioxidant status, lipid peroxidation and testis-histoarchitecture induced by chlorpyrifos in male rats.

Abstract
Mature male Wistar rats were given chlorpyrifos (5.4 mg/kg, 1/25 of the oral LD(50)), catechin (20 mg/kg),quercetin (20 mg/kg), catechin plus chlorpyrifos, and quercetin plus chlorpyrifos daily via gavage for four weeks. No statistical differences were found in the catechin-only and quercetin-only groups compared with the control group. By the end of the fourth week, chlorpyrifos alone increased the levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), while decreased glutathione peroxidase (GPx) and glutathione-S-transferase (GST) activities compared with the control group in rat testis tissues. In the catechin-plus-chlorpyrifos and quercetin-plus-chlorpyrifos groups, there were statistically significantly decreased MDA levels, SOD and CAT activities, while increased GPx and GST activities compared with the chlorpyrifos-only group. Light microscopic analyses revealed that chlorpyrifos-only induced numerous histopathological changes in the testis tissues. Milder pathological alterations were observed in rats catechin-plus-chlorpyrifos, and quercetin-plus-chlorpyrifos. Thus, it appears that catechin and quercetin ameliorate chlorpyrifos induced toxicity except histopathological changes in rat testis tissues.

Abstract
Oxidative stress is considered to be the main cause of diabetic complications. In the current study, we investigated the effect of selenium-vitamin E combination and melatonin on lipid peroxidation (LPO) and scavenging enzyme activity in the blood of streptozocin (STZ)-induced diabetic pregnant rats. Forty female Wistar rats were randomly divided into five groups. The first and second groups were used as the non-pregnant control and pregnant control groups, respectively. The third group was the pregnant diabetic group. Vitamin E plus selenium and melatonin were administered to the diabetic pregnant rats consisting fourth and fifth groups, respectively. Diabetes was induced on day 0 of the study by STZ. Blood samples were taken from all animals on the 20th day of pregnancy. LPO level was higher in diabetic pregnant rats than in control, although superoxide dismutase, catalase, and glutathione peroxidase activities were lower in diabetic pregnant animals than in control. LPO levels were lower both in the two treatment groups than in the diabetic pregnant rats, whereas selenium-vitamin E combination and melatonin caused a significant increase in the activities of these antioxidant enzymes (p<0.01). In conclusion, vitamin E plus selenium seems to be a more potent antioxidant compared to melatonin in diabetic pregnant rats. Melatonin did not significantly affect the elevated glucose concentration of diabetic pregnant treated with melatonin group. Vitamin E plus selenium may play a role in preventing diabetes-related diseases of pregnant subjects.

Abstract
Excessive generation of reactive oxygen species (ROS) can induce oxidative damage to vital cellular molecules and structures including DNA, lipids, proteins, and membranes. Recently, melatonin has attracted attention because of their free radical scavenging and antioxidant properties. The aim of this study was to evaluate the possible protective role of melatonin against atrazine-induced oxidative stress in rat erythrocytes in vivo. Adult male albino rats of Wistar strain were randomly divided into four groups. Control group received isotonic saline; melatonin (10 mg/kg bw/day) group; atrazine (300 mg/kg of bw/day) group; atrazine + melatonin group. Oral administration of atrazine and melatonin was given daily for 21 days. Oxidative stress was assessed by determining the glutathione (GSH) and malondialdehyde (MDA) level, and alteration in antioxidant enzymes such as superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), glutathione-S-transferase (GST), and glucose-6-phosphate dehydrogenase (G-6-PD) in the erythrocytes of normal and experimental animals. A significant increase in the MDA levels and decrease in the GSH was observed in the atrazine treated animals (P < 0.05). Also, significant increase in the activities of SOD, CAT, GPx, and GST were observed in atrazine treated group compared to controls (P < 0.05). Moreover, significant decrease in protein, total lipids, cholesterol, and phospholipid content in erythrocyte membrane were demonstrated in atrazine treated rats. Administration of atrazine significantly inhibits the activities of G-6-PD and membrane ATPases such as Na(+)/K(+)-ATPase, Mg(2+)-ATPase, and Ca(2+)-ATPase (P < 0.05). Scanning electron microscopic (SEM) examination of erythrocytes revealed morphological alterations in the erythrocytes of atrazine treated rats. Furthermore, supplementation of melatonin significantly modulates the atrazine-induced changes in LPO level, total lipids, total ATPases, GSH, and antioxidant enzymes in erythrocytes. In conclusion, the increase in oxidative stress markers and the concomitant alterations in antioxidant defense system indicate the role of oxidative stress in erythrocytes of atrazine-induced damage. Moreover, melatonin shows a protective role against atrazine-induced oxidative damage in rat erythrocytes.

Abstract
A large number of genome-scale networks, including protein-protein and genetic interaction networks, are now available for several organisms. In parallel, many studies have focused on analyzing, characterizing, and modeling these networks. Beyond investigating the topological characteristics such as degree distribution, clustering coefficient, and average shortest-path distance, another area of particular interest is the prediction of nodes (genes) with a given characteristic (labels) - for example prediction of genes that cause a particular phenotype or have a given function. In this chapter, we describe methods and algorithms for predicting node labels from network-based datasets with an emphasis on label propagation algorithms (LPAs) and their relation to local neighborhood methods.

Abstract
OBJECTIVE To determine the effects of pinealectomy on endometrial explants in rats and evaluate the activity of superoxide dismutase (SOD) and catalase (CAT) and the levels of malondialdehyde (MDA) in the rat endometriosis model. STUDY DESIGN Rats with experimentally induced endometriosis were randomly divided into three groups after second-look laparotomies. Group 1 (pinealectomy, n = 8) and Group 2 (pinealectomy+melatonin, n = 8) underwent pinealectomies after the second-look laparotomies. Group 3 was presented as control group (vehicle solution+without pinealectomy (n = 6)). Melatonin was administered intraperitoneally for 4 weeks in Group 2, whereas an equal volume of vehicle solution was given to Groups 1 and 3. Evaluation of the volume of the endometrial explants, histopathological examination and preservation of explant epitheliums according to the scoring system were undertaken. RESULTS There was a statistically significant increase in spherical explant volumes of Group 1 compared to Groups 2 and 3. In Group 1, the level of MDA was significantly higher and SOD and CAT activity was significantly lower compared to Groups 2 and 3. A statistically significant increase in the epithelial lining scores of explants was noted in Group 1 compared to Groups 2 and 3. CONCLUSION The effects of pinealectomy on the progression of endometriosis explants were reversed by melatonin.
