Liver is very sensitive to environmental contaminants such as pesticides, it being the first target of toxicity of a substance. The objective of this study was to investigate the possible effects of the insecticide imidacloprid (IMI) on the liver of Oreochromis niloticus according concentrations used for growing sugarcane. A semi-quantitative analysis of histopathological alterations of IMI on liver was performed by light microscopy and cellular labeling of heat shock proteins (HSP70) by immunohistochemistry. The most common changes in liver at all concentrations of IMI were hydropic degeneration, pyknotic nuclei, and loss of cell limits. Steatosis and increased levels of HSP70 were detected in hepatocytes with the highest concentration of IMI. In conclusion, the tested concentrations of IMI induced histopathological changes in the liver of O. niloticus and active defence mechanisms to maintain the morphophysiological integrity of the liver. This insecticide has a toxicity potential for these fish, which is a non-target organism of its action.

“…The distillation of sugarcane juice and molasses to produce ethanol generates large quantities of vinasse: about 10e14 L per litre of ethanol produced (Júnior et al, 2015;Orteg on et al, 2016). This effluent is characterized by strong brown colour, acidic pH, high turbidity, high content of organic compounds (acids, alcohols, aldehydes, ketones, esters and sugars) that contribute for its chemical oxygen demand (COD) and biochemical oxygen demand (BOD 5 ), and high concentration of ions (K þ , Ca 2þ , Mg 2þ , Fe 3þ , Cl À and SO 4 2À ) (Barrera et al, 2013;Christofoletti et al, 2013;Marinho et al, 2014;Orteg on et al, 2016). As vinasse presents high organic matter and nutrient contents, it has been common practice to use it as fertilizer in sugarcane fields (Júnior et al, 2014;Moraes et al, 2015).…”

“…The benefits should not be used as the sole justification for the indiscriminate disposal of vinasse into agricultural fields, so that this practice might be a palliative alternative providing a false impression of solving efficiently the management of vinasse (Fuess and Garcia, 2014). In fact, when used in large quantities, the soils become saturated and there is a risk of contamination of surface water and groundwater nearby the fields (Christofoletti et al, 2013;Marinho et al, 2014), causing serious environmental problems. Due to its strong organic matter content (high values of BOD 5 and COD), vinasse causes depletion of dissolved oxygen in surface water, lowers the pH, causes the death of aquatic fauna and flora, and introduces contaminants that hinder the use of water for human routines; further, it provides unpleasant odours (Christofoletti et al, 2013).…”

The post-treatment of biodigested sugarcane vinasse was envisaged in the present study following three different approaches: i) coagulation/flocculation e Approach 1; ii) combination of coagulation/flocculation with photo-Fenton reaction e Approach 2; iii) coagulation/flocculation followed by biological degradation and photo-Fenton reaction e Approach 3. The coagulation/flocculation per se provided a slight increase in effluent's biodegradability, a decrease in toxicity and turbidity, and provided moderate removals of total organic carbon (TOC), biochemical oxygen demand (BOD 5) and chemical oxygen demand (COD). The operating costs associated with chemicals consumption are low (5.7 R$/m 3 z 1.4 V/m 3). The second and third treatment approaches allowed to reach a nontoxic effluent, improved the biodegradability and led to similar high global organics removal efficiencies. The combined treatment consisting of coagulation/flocculation plus photo-Fenton oxidation (Approach 2) revealed to be a promising solution for treating this wastewater, in order to be recirculated into the high rate anaerobic reactor. Additionally, this solution provides smaller costs (84.9 R$/m 3 z 20.2 V/m 3) associated with chemicals and energy consumption, which are however very high. Nonetheless, this cost can be reduced by about 40% if solar radiation is used in the photo-Fenton process.

“…In this study, expression of MnGPx-3 increased at first and then decreased in the gill and hepatopancreas in response to hypoxia, while a slow decline occurred under reoxygenation (Fig 5A and 5C). Multiple studies have suggested that GPx mRNA levels can be an appropriate indicator of oxidative stress which is caused by various xenobiotics [37][38]. MnGPx-3 mRNA levels rose in the early stage of hypoxia, indicating that the hepatopancreas and gills of M. nipponense have a strong oxidative stress reaction in response to hypoxia.…”

Glutathione peroxidase (GPx) has been the focus of increased research because of its important role as an antioxidant and in reactive oxygen species (ROS) induced damage repair. Studies on GPxs have relevance with Macrobrachium nipponense because it has poor tolerance to hypoxia in Macrobrachium nipponense. The two subunits named as MnGPx-3 and MnGPx-4 according to the glutathione peroxidase nomenclature system. Both full-length cDNAs were cloned from the hepatopancreas. In this study, we analyzed the expression of two GPxs in Macrobrachium nipponense in response to changes in environmental oxygen. Expression levels of MnGPx-3 and MnGPx-4 indicated that both have strong responses to hypoxia. In situ hybridization showed that MnGPx-3 and MnGPx-4 were located in secretory and storage cells in hepatopancreas. These results suggest that GPx gene is expressed and released by secretory cells and released response to hypoxia. In the gill tissue, however, GPxs are located in blood cells, suggesting that they perform different functions in different tissues or organs. The results of in situ hybridization were consistent with those of quantitative Real-time PCR. This study provides a basis for understanding the oxidative stress response in M. nipponense under hypoxia.
