Dietary manganese requirement of fingerling Indian major carp, Labeo rohita (Hamilton) estimated by growth, tissue manganese concentration and hepatic manganese-superoxide dismutase activity

Blue Fluorescent Nitrogen‐Doped Carbon Dots for the Specific Detection of Mn2+

“…Manganese (Mn) is one of the elements widely distributed in the earth‘s crust, frequently co‐occurring with iron [1] . As one of the essential trace elements in human body, manganese is the cofactor of numerous enzymes in the biological system and has crucial physiological roles in the body [2] . And it has vital physiological functions in promoting bone development, [3] ensuring healthy brain metabolism, maintaining normal sugar metabolism [4] and fat metabolism, [5] and improving the hematopoietic function of the body [6] .…”

Effects of dietary tryptophan on the antioxidant capacity and immune response associated with TOR and TLRs/MyD88/NF-κB signaling pathways in northern snakehead, Channa argus (Cantor, 1842)

“…In addition, the lipid peroxidation of ROS with polyunsaturated fatty acids (PUFA) in the cell membrane, and the end products of peroxidation, such as malondialdehyde (MDA), have toxic effects on cells (16,17). Total antioxidant capacity (T-AOC), superoxide dismutase (SOD) and catalase (CAT) are important components of the antioxidant defense system in fish, which can remove excess ROS in the body, and maintain normal physiological and life activities (16,18). Supplementation of amino acids in the diet has improved antioxidant capacity and reduced oxidative stress in several fish (19)(20)(21).…”

“…When fish are subjected to oxidative stress, the content of reactive oxygen species (ROS) in fish increases ( 13 , 14 ), which can attack macromolecules such as proteins and nucleic acids in the organism, leading to oxidative damage ( 15 ). In addition, the lipid peroxidation of ROS with polyunsaturated fatty acids (PUFA) in the cell membrane, and the end products of peroxidation, such as malondialdehyde (MDA), have toxic effects on cells ( 16 , 17 ). Total antioxidant capacity (T-AOC), superoxide dismutase (SOD) and catalase (CAT) are important components of the antioxidant defense system in fish, which can remove excess ROS in the body, and maintain normal physiological and life activities ( 16 , 18 ).…”
