Abstract
Hospital effluent (HE) is one of the most important sources of pharmaceuticals released into the environment. This kind of pollution is a recognized problem for both human health and aquatic life. Consequently, in the present study, we assessed the effects of untreated hospital effluent on mice via biochemical and histopathological determinations. Female mice were given free access to water bottles containing untreated HE at different dilutions for 21 days. Then clinical biochemistry and histopathology evaluation were conducted. Serum biochemistry analysis showed the presence of significant increase in cholesterol, triglycerides, glycaemia and total bilirubin. However, phosphatase alkaline and urea activities have been significantly decreased compared to the control group. No significant variation was observed for the rest of the studied parameters (high-density lipoproteins; low-density lipoproteins and uric acid). Additionally, multiple alterations, including cellular necrosis, leucocyte infiltration and congestion, were observed in different tissues of mice exposed to the tested HE.

Protective effect of astaxanthin against SnS 2 nanoflowers induced testes toxicity by suppressing RIPK1-RIPK3-MLKL signaling in mice. Food Chem Toxicol 2020; 145:111736.

Abstract
The reproductive toxicity of SnS2 nanoflowers (SnS2 NFs) has been studied in our previous experiment, but the underlying mechanism is still not clear. Astaxanthin (ASX) is a red carotenoid pigment with antioxidant, anticancer and anti-inflammatory properties, showing neuroprotective properties via its antioxidant capacity. To examine the ASX effect on sub-chronic testis injury induced by SnS2 NFs, we randomly and equally divided 40 Kunming male mice into four groups (control, ASX control, NF and NF + ASX groups). Then, ASX dissolved in olive oil was administered intragastrically for 30 consecutive days. Results showed that ASX treatment improved the sperm parameters in mice. Meanwhile, the ASX treatment significantly attenuated testis histopathological injury and ultrastructure alterations induced by SnS2 NFs. It also alleviated testicular oxidative stress, inflammation, apoptosis and necroptosis in mice. Furthermore, ASX markedly upregulated the expression of Bcl-2 and downregulated the expressions of Fas, FasL, RIPK1, FADD, Bax, Cytochrome C, Caspase-9, Cleaved Caspase-8, Cleaved Caspase-3, RIPK3, MLKL and FLIP in the testis tissues compared with the NF group. Therefore, ASX had a markedly protective effect against SnS2 NFs in mice, and the potential mechanism is associated with its ability to inhibit the oxidative stress, inflammatory response, testicular apoptosis and necroptosis, as well as downregulating in the expression of the RIPK1-RIPK3-MLKL signaling and mitochondrial related apoptosis genes.

Abstract
The liver is one of the most important multi-functional organs in the human body. Amongst various crucial functions, it is the main detoxification center and predominantly implicated in the clearance of xenobiotics potentially including particulates that reach this organ. It is now well established that a significant quantity of injected, ingested or inhaled nanomaterials (NMs) translocate from primary exposure sites and accumulate in liver. This review aimed to summarize and discuss the progress made in the field of hepatic nanotoxicology, and crucially highlight knowledge gaps that still exist.Key considerations include In vivo studies clearly demonstrate that low-solubility NMs predominantly accumulate in the liver macrophages the Kupffer cells (KC), rather than hepatocytes.KCs lining the liver sinusoids are the first cell type that comes in contact with NMs in vivo. Further, these macrophages govern overall inflammatory responses in a healthy liver. Therefore, interaction with of NM with KCs in vitro appears to be very important.Many acute in vivo studies demonstrated signs of toxicity induced by a variety of NMs. However, acute studies may not be that meaningful due to liver's unique and unparalleled ability to regenerate. In almost all investigations where a recovery period was included, the healthy liver was able to recover from NM challenge. This organ's ability to regenerate cannot be reproduced in vitro. However, recommendations and evidence is offered for the design of more physiologically relevant in vitro models.Models of hepatic disease enhance the NM-induced hepatotoxicity.The review offers a number of important suggestions for the future of hepatic nanotoxicology study design. This is of great significance as its findings are highly relevant due to the development of more advanced in vitro, and in silico models aiming to improve physiologically relevant toxicological testing strategies and bridging the gap between in vitro and in vivo experimentation.

Abstract
Recently, interest in the potential applications of tin disulphide nanoflowers (SnS2 NFs) in the treatment of waste water and their antibacterial properties has increased. However, their effects on neurotoxicity, brain cognition and behavioural injury, as well as the underlying mechanisms of these effects have remained unknown. In the present study, we compared the neurotoxicity of SnS2 NFs (50 nm) administered intragastrically at different doses (5, 10, and 50 mg kg-1) in mice for 60 days. The results showed that the neurotoxicity of SnS2 NFs in mice is dose-dependent. Furthermore, expression levels of genes related to oxidative stress, metabolism and signal transduction were also modified in the brain tissues of mice exposed to SnS2 NFs, supporting the SnS2 NF-dependent neurotoxic phenotype. Additionally, SnS2 NF exposure resulted in an abnormal ultrastructure in the hippocampus of the treated mice. Nevertheless, their body weight, organ coefficient and behaviour assessed in an open-field test and learning and memory test results assessed using a Morris water maze test remained unaffected. This suggested that the increased risk of neurotoxicity in SnS2 NF-treated mice was dependent on the dosage of SnS2 NFs. The relative level of safety was <5 mg kg-1 for 50 nm SnS2 NFs. The present study provides an experimental basis for the safe application of SnS2 NFs; however, chronic behavioural effects of SnS2 NFs remain unknown.
