Fate of COD and ammonia-nitrogen in a highly stressed watercourse in Northern China: the Zhangweinan Canal basin

Water International, 2011
A simple method is presented to assess the accumulation of chemical oxygen demand (COD) and ammonia-nitrogen (NH3−N) loads as applied to the Zhangweinan Canal basin, one of the most highly stressed watercourses in the heavily developed Hai River basin in China. The river was divided into seven monitoring sections. The pollution sources and processes in

Cooperative adaptation strategies of different tissues in blunt snout bream (Megalobrama amblycephala) juvenile to acute ammonia nitrogen stress

Environmental Science and Pollution Research, 2023
Ammonia-nitrogen is a common stress factor for aquatic organisms in their habitation environment, which is enriched in water due to high-density farming and environmental pollution. Ammonia nitrogen can enter fish body through gill, epidermis, digestive tract, and other tissues, causing fish ammonia poisoning. In the present study, juvenile blunt snout

miR-2765 involved in ammonia nitrogen stress via negative regulation of autophagy in shrimp

International Journal of Biological Macromolecules
MicroRNA (miRNA) is a highly conserved non-coding tiny endogenous RNA molecule that regulates various cellular functions by inhibiting mRNA translation or promoting the degradation of proteins. In this study, we identified a specific miRNA (designed as Pva-miR-2765) from Penaeus vannamei, which widely distributed in different tissues of shrimp, with ...

Dietary nano cerium oxide promotes growth, relieves ammonia nitrogen stress, and improves immunity in crab (Eriocheir sinensis)

Fish & Shellfish Immunology, 2019
Oxidative stress plays a crucial role in ammonia nitrogen toxicity. In this study, the beneficial effects of dietary nano cerium oxide (nano CeO2) as a potent antioxidant were examined in the Chinese mitten crab (Eriocheir sinensis). Crabs were fed a diet supplemented with 0, 0.2, 0.4, 0.8, 1.6, 3.2, 6.4, or 12.8 mg/kg nano CeO2 for 60 d.

Transcription factor GATA5 enhances autophagy by modulating miR-2765 in Penaeus vannamei under ammonia nitrogen stress

International Journal of Biological Macromolecules
The transcription factor GATA is recognized as a key regulator of cell generation and differentiation, playing a significant regulatory role in immune responses triggered by both biotic and abiotic stress. However, the regulatory network of GATA in crustaceans remains poorly understood.

The study of MDM2 binding protein (MTBP) in response to apoptosis in Litopenaeus vannamei under ammonia and nitrite nitrogen stress

Fish & Shellfish Immunology
MDM2 binding protein (MTBP) is a protein that interacts directly with MDM2. This study characterized the LvMTBP, revealing a 2752 bp cDNA sequence encoding an 834-amino acid hydrophilic protein with conserved MTBP_N and MTBP_C domains. Phylogenetic analysis demonstrated close evolutionary relationships with Penaeus species.

Interaction Effects between Micropterus salmoides and Edwardsiella piscicida under Ammonia Nitrogen or Nitrite Stress

This study investigated the interactive effects of ammonia nitrogen (AN) and nitrite stress on largemouth bass (Micropterus salmoides) in the context of Edwardsiella piscicida (E. piscicida) infection. The results indicated that a combined stress of 2 mg/L nitrite initially induced a short-term immune enhancement in the host.
