Using Oreochromis niloticus for Assessment of Water Quality in Water Treatment Plants
The present study was suggested in order to explore the capability of water treatment plants to induce changes in organisms using the fish as a model. To achieve such a purpose, Oreochromis niloticus were chosen as a test material for the study. Two hundred apparently healthy Oreochromis niloticus were divided into 7 groups (control and 3 different WTPs) to assess differences developed from wat...
متن کاملEffects of Sublethal Nitrite and Ammonia in Oreochromis Niloticus L. Infected with Edwardsiella Tarda
In this study, the effects of sublethal nitrite and sublethal ammonia on experimentally infected Nile Tilapia’s haematological and immunological parameters have been investigated. The groups were K: control group, Group A: ammonia exposed group, AB: infected with Edwardsiella tarda and exposed to ammonia, Group N: nitrite exposed group, NB: infected with E. tarda and exposed to nitrite, B: infe...
متن کاملA novel cold-adapted imidase from fish Oreochromis niloticus that catalyzes hydrolysis of maleimide.
In this paper we report the first comparative study of cold-adapted imidase (EC 3.5.2.2) from the fish (Oreochromis niloticus) liver and its thermophilic counterparts taken from pig liver and Escherichia coli (overexpressed recombinant hydantoinase from Agrobacterium radiobacter NRRL B1). Approximately 6000-fold purification and a 40% yield of fish imidase activity were obtained through ammoniu...
متن کاملCloning and Characterization of Type III Iodothyronine Deiodinase from the Fish Oreochromis niloticus.
Type III iodothyronine deiodinase (D3) catalyzes the inner ring deiodination (IRD) of T4 and T3 to the inactive metabolites rT3 and 3,3'-diiodothyronine (3,3'-T2), respectively. Here we describe the cloning and characterization of complementary DNA (cDNA) coding for D3 in fish (Oreochromis niloticus, tilapia). This cDNA contains 1478 nucleotides and codes for a protein of 267 amino acids, inclu...
متن کاملCadmium and Lead Alter the Antioxidant and Osmoregulation Systems in the Erythrocyte of Fish (Oreochromis niloticus)
The erythrocytes deliver oxygen to all around body cells that make them extremely vital for the metabolism. Metals are transferred through the blood, meaning the erythrocytes face with metals continuously. The present study intended to explore the responses of osmoregulation (Na/K-ATPase, Mg-ATPase, Ca-ATPase) and antioxidant system parameters (CAT, SOD, GPX, GR, GST, tGSH, rGSH, GSSG, GSH/GSSG...
