Mechanism of digestion enzymes and related genes in response to acute ammonia-nitrogen stress in juvenile yellowfin tuna (Thunnus albacares)

Marine Environmental Research
To investigate the impact of acute ammonia stress (NH3-N) on the digestive physiology and gene expression in juvenile yellowfin tuna (Thunnus albacares), we used natural seawater (0 mg/L ammonia) as the control. Ammonia concentrations of 5 and 10 mg/L were set to measure the levels of digestive enzymes in the intestine, liver, stomach, and pyloric ...

Fluoride stress regulates microbial-induced calcium precipitation: Synergistic removal of high ammonia nitrogen and fluoride and response mechanism

Environmental Research
Deep treatment of photovoltaic wastewater is one of the core environmental challenges constraining its green development. This study isolated a salt-tolerant strain, Acinetobacter LX-6, exhibiting both efficient heterotrophic nitrification-aerobic denitrification and biomineralization capabilities.

Algal-Bacterial Symbiosis System Tolerant to High Ammonium Nitrogen: From Acclimation to Ammonia Stress Response

Algal-bacterial symbiosis (ABS) systems represent a highly promising approach for treating wastewater, yet how to establish ammonia-tolerant ABS systems through acclimation and the underlying tolerance mechanisms remain poorly understood. In this study, a novel acclimation strategy was developed to construct ammonia-tolerant ABS systems under high ...

Value of rest-stress myocardial positron tomography using nitrogen-13 ammonia for the preoperative prediction of reversible asynergy.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1989
To determine the predictive value of stress [13N]ammonia positron emission tomography (PET) for reversible ischemia, 31 patients with coronary artery disease underwent rest-stress [13N]ammonia PET before and after coronary artery bypass surgery. The circumferential profile analysis was applied to determine the presence of transient defect (TD) and ...
