Triple-mode sensing platform for acetylcholinesterase activity monitoring and anti-Alzheimer's drug screening based on a highly stable Cu (I) compound.

Acetylcholinesterase (AChE) and AChE inhibitors play critical roles in the early diagnosis and treatment of Alzheimer's disease (AD). Herein, a fluorescence/colorimetry/smartphone triple-mode sensing platform was constructed for both AChE activity monitoring and AChE inhibitor screening by exploring a Cu (I) compound, CuI (SR) (R = CHCHNH), as a fluorescent probe. In comparison of most other fluorescent probes, CuI (SR) presented exceptional stability against pH, temperature, UV irradiation, redox agents, and metal ions, as well as good recyclability due to its unique chemical structure.

The optimal denitrification conditions for SSAD and SLAD systems were pH of 7, HRT of 3 h, temperatures of 20-25 °C with NO-N removal rates of more than 99%.

YTHDF1 in periaqueductal gray inhibitory neurons contributes to morphine withdrawal responses in mice.

Mild to moderate drought stress reinforces the role of functional microbiome in promoting growth of a dominant forage species () in desert steppe.

Background: Desert steppe ecosystems are prone to drought stress, which influences the ecological balance and sustainable development of grasslands. In addition to directly restrict plant growth, drought stress indirectly impacts plant fitness by altering the diversity and function of root-associated microbiomes. This begs the question of whether the functional microbiome of forage plants, represented by synthetic microbial communities (SynComs), can be leveraged to mitigate drought stress in desert steppes and promote the ecological restoration of these fragile ecosystems.

Nitrate Reduction by NiFe-LDH/CeO: Understanding the Synergistic Effect between Dual-Metal Sites and Dual Adsorption.

Electrocatalytic nitrate reduction reaction (EC-NITRR) shows a significant advantage for green reuse of the nitrate (NO) pollutant. However, the slow diffusion reaction limits the reaction rate in practical EC-NITRR, causing an unsatisfactory ammonia (NH) yield.

Fluorometric and colorimetric dual-mode sensing of α-glucosidase based on aggregation-induced emission enhancement of AuNCs.

Herein, a fluorometric and colorimetric dual-mode assay platform used for α-glucosidase (α-Glu) activity sensing based on aggregation-induced emission enhancement (AIEE) of AuNCs was developed for the first time. The quantum yield (QY) and fluorescence lifetime of AuNCs were successfully ameliorated by Ce-triggered AIEE (Ce@AuNCs).
