The liver‐brain axis: A multidimensional regulatory network implicated in Alzheimer's disease pathogenesis and clinical implications

Animal Models and Experimental Medicine, EarlyView.
Schematic diagram of the core pathways of the liver‐brain axis in regulating AD. The liver regulates cerebral Aβ deposition, tau phosphorylation, and neuroinflammation through pathways such as metabolic detoxification (urea cycle, ketone body metabolism, glutathione antioxidant system), molecular secretion (APOE, CRP, FGF21, IGF‐1), and Aβ clearance ...

Carbon‐Confined Fe3C/Fe3N Janus Interfaces for Selective Nitric Oxide‐to‐Ammonia Electroreduction

Angewandte Chemie, EarlyView.
A defect‐rich, graphitic‐carbon‐confined Fe3C/Fe3N Janus catalyst integrates NO transport, adsorption/activation, and interfacial H supply for efficient nitric oxide electroreduction to ammonia. Built from earth‐abundant elements, this architecture enables high‐yield and high‐efficiency NH3 synthesis while valorizing industrial NO emissions.

Assembly of Bioactive Superstructures via Metal–Phenolic Complexation for Blood Purification

Angewandte Chemie, EarlyView.
Bioactive superstructures are assembled via metal–phenolic‐mediated assembly on agarose templates, followed by modification with human serum albumin. These superstructures demonstrate high bilirubin adsorption efficiency, strong antibacterial activity, and anticoagulant activity, providing a strategy for the rational design of multifunctional blood ...

Contribution of ammonia-oxidizing archaea and ammonia-oxidizing bacteria to ammonia oxidation in two nitrifying reactors

Environmental Science and Pollution Research, 2018
In this study, two laboratory nitrifying reactors (NRI and NRII), which were seeded by sludge from different sources and operated under different operating conditions, were found to possess distinct dominant ammonia-oxidizing microorganisms. Ammonia-oxidizing archaeal (AOA) amoA genes outnumbered ammonia-oxidizing bacterial (AOB) amoA genes in reactor ...

Ammonia-Oxidizing Bacteria in Wastewater

2011
Ammonia-oxidizing bacteria (AOB) have a key role in the conversion of ammonia to nitrite in wastewater treatment plants (WWTPs). The characterization of AOB communities in such systems requires the use of genomic methods as AOB are difficult to isolate from environmental samples.

Ammonia-oxidizing activity and microbial structure of ammonia-oxidizing bacteria, ammonia-oxidizing archaea and complete ammonia oxidizers in biofilm systems with different salinities

Bioresource Technology
Ammonia-oxidizing activity of different ammonia-oxidizing microorganisms (AOMs), such as ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA), and complete ammonia oxidizers (comammoxs), were investigated by adding the inhibitors such as 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl 3-oxide, octyne, and KCLO3 in biofilm systems with ...

The Oxidation of Ammonia

Nature, 1919
IT is regretted that there is an error in the second equation of those suggested in NATURE of April 24 which makes the scheme there given impossible. The writer still considers that nitrohydroxylamic acid is a possible intermediate product, as will be explained below, but it cannot be derived as previously given.

The production of nitric oxide by marine ammonia‐oxidizing archaea and inhibition of archaeal ammonia oxidation by a nitric oxide scavenger

Environmental Microbiology, 2015
Summary Nitrification is a critical process for the balance of reduced and oxidized nitrogen pools in nature, linking mineralization to the nitrogen loss processes of denitrification and anammox. Recent studies indicate a significant contribution of ammonia‐oxidizing archaea ( AOA

Ammonia Oxidizing Bacteria

2023
Ammonia oxidising bacteria (AOB) and archaea are ubiquitous microorganisms, but their abundance and diversity vary widely across environments and play a crucial role in many ecosystems and aquatic ecosystems in particular. However, characterization of AOB communities require genomic methods as they are difficult to isolate from samples.
