This study aimed to determine the potential toxicological effects of carbon nanotubes (CNTs), their modifications with ethylenediamine (ED) and boric acid (BA) on aquatic organisms. Specifically, the research focused on the morphological, physiological, and histopathological-immuno-histochemical responses in zebrafish (Danio rerio) embryos and larvae, via applying different concentrations of CNTs, CNT-ED, and CNT-ED-BA (Control, 5, 10, and 20 mg/L). The results indicated that 20 mg/L CNT nanoparticles were toxic to zebrafish larvae, with mortality rates increasing with CNT and CNT-ED concentra ...Дагы
1. Aflatoxins (AFs) are metabolites which especially have toxic effects on proteins, and are detoxified by the aflatoxin-B-1 aldehyde reductase (AFAR) pathway. In this pathway, the aldo-keto reductase family 7, member A2 (AKR7A2) enzyme, which is controlled by nucleic-related erythroid factor 2 (Nrf2), plays an active role. However, data on the efficacy of this critical pathway in broilers is limited. 2. The aim of the following study was to investigate the changes in the expression levels of AKR7A2, Nrf2, and caspase-3, and the effects of Nigella sativa seeds (NS), thymoquinone (TMQ), and ben ...Дагы
Many lichen secondary metabolites contributed to the field of pharmacology as an active ingredient of different drugs for years. In the present study, we aimed to test the anticancer activity of olivetoric acid (OA), which we isolated from Pseudevernia furfuracea (L.) Zopf in human hepatocellular carcinoma cells (HepG2). In addition, we used non-tumoral human liver cells (THLE2) to test the level of side effects of OA in vitro. For this purpose, cytotoxic (apoptotic and necrotic), oxidant, genotoxic activities and expression levels of apoptotic genes caused by different concentrations (12.5-40 ...Дагы
In the present study, we investigated the protective effect of magnolin (MAG) against oxidative stress induced by cyclophosphamide (CP) and its role in the Nrf2/HO-1 signaling pathway. Rats were administered MAG (1 mg/kg, i.p.) for 14 days and CP (75 mg/kg, i.p.) on the 14th day. CP administration increased tissue damage, as evidenced by elevated levels of transaminases (aspartate and alanine), alkaline phosphatase, and renal parameters (blood urea nitrogen and creatinine). Additionally, 8-hydroxy-2́-deoxyguanosine and malondialdehyde levels were increased, whereas glutathione levels, along wi ...Дагы
