Determination of urinary ammonium excretion is helpful in evaluating patients with acid-base disorders, chronic kidney disease, and nephrolithiasis. However, urinary ammonium levels are only measured by specialized laboratories in the United States, limiting widespread implementation. We evaluated the performance of a plasma ammonium assay to quant...

Nitrogen (N) isotope ratios (δ15N) of multiple N species including ammonium (NH4 +), nitrate (NO3 −), dissolved organic N (DON), and total dissolved N (TDN) can serve as indicators of the sources of wet N deposition. However, methods for sequential analysis of these multiple N species are not well developed. In this study, methods for the determina...
Nitrogen (N) is an essential element for plant growth and development. The application of a balanced and optimal amount of N is required for sustainable plant yield. For this, different N sources and forms are used, that including ammonium (NH4+) and nitrate (NO3−). These are the main sources for N uptake by plants where NH4+/NO3− ratios have a sig...

Nitrate (NO3−) and ammonium (NH4+) are the primary forms of inorganic nitrogen acquired by plant roots. LncRNAs, as key regulators of gene expression, are a class of non-coding RNAs larger than 200 bp. However, knowledge about the regulatory role of lncRNAs in response to different nitrogen forms remains limited, particularly in woody plants. Here,...

The role of the liver in the metabolism of toxic compounds and in Aβ and α-synuclein clearance is related to neurological disorders such as Alzheimer’s Ddisease (AD) and Parkinson’s Disease (PD) development, although the supplementation with certain compounds may exert a protective effect. The current Western diet and alterations in the BA profile,...
The review describes the place of membrane methods in solving the problem of the recovery and re-use of biogenic elements (nutrients), primarily trivalent nitrogen NIII and pentavalent phosphorus PV, to provide the sustainable development of mankind. Methods for the recovery of NH4+ − NH3 and phosphates from natural sources and waste products of hu...

It is effective to adsorb phosphate and ammonium from water by sludge-based biochar, while the desorption performance has not been studied systematically. Biochar in this study was prepared through the co-pyrolysis of sludge and walnut shells to remove NH4+ and PO43- from water. The desorption characteristics of NH4+ and PO43- from the post-adsorpt...

The Sharply increasing atmospheric nitrogen (N) deposition may substantially impact the N availability and photosynthetic capacity of terrestrial plants. Determining the trade-off relationship between within-leaf N sources and allocation is therefore critical for understanding the photosynthetic response to nitrogen deposition in grassland ecosyste...

This article presented new sequences of fish gelatin (FG) as a polymer host for solid polymer electrolytes (SPEs) impregnated with ammonium nitrate (NH4NO3) and the impact of different amounts of salt on the properties of the formed electrolyte were investigated. X-ray diffraction (XRD) analysis revealed that the electrolyte containing 25 wt.% NH4N...
