Tetracyclines (TCs) residues pose a significant threat to the aquatic environment and human health, therefore this study aims to develop a simple, rapid, and sensitive TCs detection method. Herein, a dual-responsive gel probe (LDH-CES@N) was designed, consisting of the intercalation of graphene quantum dots into europium-doped layered double hydroxide (LDH). In the presence of TCs, the as-prepared probe exhibited dual emission fluorescence at 504 nm and 616 nm due to the synergistic effect of aggregation-induced emission and antenna effect.

An in situ self-cleaning covalent organic framework featuring arylbiguanide arms (Aryl-BIG-COF) was first developed to remove emerging organic pollutants such as propranolol (PRO) from water. The main breakthroughs addressed the scarcity of functional active sites, the impracticality of ex situ regeneration, and the rapid recombination of electronhole pairs in the application of COFs. Owing to the directional capture ability and electronic structure regulation of the arylbiguanide arms, the adsorption capacity and photocatalytic degradation rate of the newly synthesized COF increased by nearly four and seven times, respectively.

Background: Studies suggest a potential link between stroke and Alzheimer's disease wherein stroke may serve as a trigger for the onset or acceleration of Alzheimer's pathogenesis as damage to the brain's blood vessels may lead to the accumulation of amyloid beta protein which is a hallmark of Alzheimer's disease. Recent research has shown that stroke treatment may hold the key to treating Alzheimer's disease. The anti-inflammatory potentials of Cholinergic signaling are a novel therapeutic target in memory decline associated with Alzheimer's.

Background: One of the pathological hallmarks in Alzheimer's disease (AD) brain is neurofibrillary tangles (NFTs) composed of highly phosphorylated tau protein. Clinical benefit of traditional Japanese Kampo Yokukansan for dementia patients, including AD was suggested. In this study, we investigated whether yokukansan participates in the degradation of phosphorylated tau and toxic oligomeric species of tau by using cell culture model of tauopathy, M1C cells.
