Herein, we report a new phenolphthalein appended Schiff base (PASB) as reversible fluorescent sensor for the detection of pyrophosphate (PPi) ions through the metal displacement mechanism. PASB showed sensing exclusively toward Al ions in DMF/HO (v/v = 1/4, pH 5.5) solution, which resulted in a significant fluorescence enhancement at 540 nm. The 1: 2 binding stoichiometry for the complex formation between PASB and Al was confirmed by Job's plot and mass spectroscopic studies. Moreover, a solution of the in situ formed PASB-Al complex displayed a high selectivity to PPi. The addition of PPi to PASB-Al ensemble significantly quenched its fluorescence. Thus, a dual response was established based on "Off-On-Off" strategy for detection of both Al and PPi. The detection limit is 5.86 nM and 26 nM for Al and PPi, respectively. On this basis, we use PASB to detect Al in food samples. Furthermore, PASB was successfully applicable to detect Al and PPi for intracellular imaging in Human liver cancer cells.

This study was designed to investigate the protective effect and mechanism of Sufentanil on acute lung injury in septic mice based on network pharmacology and animal experiments, and to provide new ideas for clinical treatment. To this end, a protein-protein interaction (PPI) network for common targets was first constructed with Swiss Target Prediction Database, GeneCards Database, Draw Venn Diagram Software, STRING 11.5 Database, Cytoscape 3.

Lymphocytic esophagitis (LE) is an uncommon subtype of esophagitis defined by persistent esophageal inflammation characterized by a high count of intraepithelial lymphocytes with scarce granulocytes. Although LE can present with atypical features such as chest pain, its clinical presentation can mimic that of gastroesophageal reflux disease or eosinophilic esophagitis, highlighting the importance of biopsy in diagnosing LE. Studies are still limited in understanding the pathophysiology behind this disease warranting further research.

This study reports on the influence of lactic acid fermentation on the proteomic and peptidomic profiles of spirulina protein isolate (SPI)-fortified, freeze-dried powders containing living Lacticaseibacillus rhamnosus GG (LGG) cells during in vitro digestion. For comparison, powders fortified with whey protein isolate (WPI) and pea protein isolate (PPI) were also evaluated. Prior to freeze-drying, the powder precursors were either non-treated or fermented.

Background: Rheumatoid arthritis (RA) is an inflammatory disease of the joints mediated by immune cells. As an immune-related mode of cell death, pyroptosis has yet to be fully understood in RA. This research identified novel pyroptosis-related markers in RA and confirmed its functional significance in RA.
