Kidney stones are a common urological disorder with increasing prevalence worldwide. The treatment of kidney stones mainly relies on surgical procedures or extracorporeal shock wave lithotripsy, which can effectively remove the stones but also result in some complications and recurrence. Therefore, finding a drug or natural compound that can prevent and treat kidney stones is an important research topic. In this study, we aimed to investigate the effects of yellow tea on kidney stone formation and its mechanisms of action. We induced kidney stones in rats by feeding them an ethylene glycol diet and found that yellow tea infusion reduced crystal deposits, inflammation, oxidative stress, and fibrosis in a dose-dependent manner. Through network pharmacology and quantitative structure-activity relationship modeling, we analyzed the interaction network between the compounds in yellow tea and kidney stone-related targets and verified it through in vitro and in vivo experiments. Our results showed that flavonoids in yellow tea could bind directly or indirectly to peroxisome proliferator-activated receptor gamma (PPARG) protein and affect kidney stone formation by regulating PPARG transcription factor activity. In conclusion, yellow tea may act as a potential PPARG agonist for the prevention and treatment of renal oxidative damage and fibrosis caused by kidney stones.

Developing dithienylethene (DTE)-based fluorescence switches triggered by biocompatible visible light has always been a long-term goal in view of their potential in numerous biological scenarios. However, their practical availability is severely limited by the short visible light (generally less than 500 nm) required for photocyclization, their inability to achieve red or near-infrared emission, and their short fluorescence lifetimes. Herein, we present a novel DTE derivative featuring a dimethylamine-functionalized BF-curcuminoid moiety (NBDC) by using an "acceptor synergistic conjugation system" strategy.

A simple, tailor-made, novel chemosensor based on 1,10-phenanthroline Schiff base incorporating N, N-Diethylamino salicylaldehyde (1) was designed and synthesized. The sensing ability of chemosensor 1 was tested via colorimetric, UV-Vis and fluorescence spectroscopy. Chemosensor 1 could effectively and specifically detect diethylchlorophosphate (DCP) in acetonitrile displaying naked eye colour change from pale yellow to dark yellow while fluorogenic colour changes from blue to pink fluorescence (365 nm UV lamp irradiation).

Article Synopsis
- Lithocarpus polystachyus, known as 'sweat tea,' is an important tree in China whose leaves are beneficial for diabetes treatment due to their high dihydrochalcone content.
- In January 2024, a significant disease outbreak was reported on these trees in Hunan Province, affecting about 74% of surveyed plants, with symptoms evolving from small yellow lesions to large brown patches and ultimately leaf necrosis.
- Pathogen isolation methods revealed that the fungus responsible for the disease was identified as Diaporthe sp., confirmed by examining colony characteristics and genomic DNA analysis.

The human intestinal tract plays a pivotal role in safeguarding the body against noxious substances and microbial pathogens by functioning as a barrier. This barrier function is achieved through the combined action of physical, chemical, microbial, and immune components. Tea (Camellia sinensis) is the most widely consumed beverage in the world, and it is consumed and appreciated in a multitude of regions across the globe.
