Biological denitrification is limited by slow nitrate (NO3-) reduction due to low electron transfer efficiency, unsatisfactory community functional efficiency and insufficient metabolic activity of microbial communities. To overcome these challenges, Ni2+ and Fe2+ were incorporated with gallic acid (GA) to form bimetallic polyphenol networks (NiFeGA BPNs) ...

Background: One of the main neuropathological hallmarks of Alzheimer's disease (AD) is the accumulation of amyloid-beta oligomers (Aßo), which begins in the brain approximately 15 years prior to the onset of clinical symptoms. Aßo-induced neuronal hyperactivity has emerged as an early functional characteristic of AD, contributing to synaptic deficits, ...

Background: Tau pathology is an important neuropathological marker of Alzheimer's Disease (AD) and correlates closely with neurodegeneration and cognitive decline. To date, much of the work examining tau propagation has been performed using mutated tau and/or transgenic animal models. Since t ...

Sulfur autotrophic denitrification (SAD) offers a sustainable solution for nitrogen removal in low carbon to nitrogen ratio (C/N) municipal wastewater, yet its efficiency and startup time pose significant challenges. To overcome these, we developed iron-sulfur-modified carriers (FeS@MC) and integrated them into an in-situ sequencing batch reactor (S-Fe-SB ...

Studying ion transport in the interaction confinement regime has important implications for membrane design and advanced electrochemical devices. A key example is the rapid-charging capability of aqueous organic redox flow batteries, enabled by near-frictionless Na+/K+ transport within triazine framework membranes. However, achieving similar breakthroughs ...

In Alzheimer's disease, there is an imbalance in neurotransmitter release and altered neuronal activation. Here, we present a protocol approach to analyze neuronal activity by combining local field potential (LFP) recording with microdialysis within the same animal. We describe steps for measuring glutamate and GABA levels following hippocampal amyloi ...

Astrocytes critically shape whole-brain structure and function by forming extensive gap junctional networks that intimately and actively interact with neurons. Despite their importance, existing computational models of whole-brain activity ignore the roles of astrocytes while primarily focusing on neurons. Addressing this oversight, we introduce a biophys ...

Background: Tau aggregates in Alzheimer's disease (AD) induce loss of synapses and neurons, leading to cognitive impairment. Predicting tau and neurodegeneration temporal evolution could be used for prognostication and for assessing results of therapeutic trials. Tau PET and MRI volumetry are ...

A novel multi-signal functional material consisting of Hematin, Fe, and guanosine monophosphate (GMP) was successfully constructed (Hematin@Fe/GMP) to enhance denitrification efficiency based on the signal network regulation of electron transfer, micromolar Fe utilization, and microbial community. Hematin@Fe/GMP enhanced nitrate reduction rate by 2.33-fol ...

In this study, a functionally stable insoluble Cu/Fe nanoparticles (Cu/Fe NPs) were synthesized and applied denitrification with different contaminants. The results showed that 50 mg/L Cu/Fe NPs increased NO3--N reduction rate up to 14.3 mg/(L·h) about 3 folds compared with the control system (4.7 mg/(L·h)), and Cu/Fe NPs exhibited excellent restorative e ...
