Irisin regulates integrin αvβ5/FAK/ERK to inhibit neutrophil extracellular traps formation and reduce pancreatic beta-cells pyroptosis in type 2 diabetes mellitus.

Background: Dysregulation of neutrophil extracellular traps (NETs), through overproduction or poor clearance, can lead to tissue damage and is linked to inflammatory conditions like type 2 diabetes mellitus (T2DM). Irisin, a hormone believed to modulate energy metabolism and enhance insulin sensitivity, holds promise as a potential treatment for T2DM. This study aims to investigate the role of Irisin in alleviating β-cell pyroptosis by inhibiting NETs formation and elucidating the underlying molecular mechanisms.

2-Bromohexadecanoic Acid as a Novel Bidentate Ligand for Passivation of Cesium Lead Halide Perovskite Nanocrystals with Near-Unity Photoluminescence Quantum Yield and Superior Photostability.

Halide vacancies on the surfaces of cesium lead halide perovskite (CsPbX, X = Cl, Br, or I) nanocrystals (NCs) play a crucial role in their photoluminescence quantum yield (PLQY) and photostability. However, effectively passivating these vacancies remains a challenge. Here, 2-bromohexadecanoic acid (BHA) is introduced as a bidentate auxiliary ligand for CsPbX NCs.

Enhancing the Optical Properties and Stability of CsPbBr Quantum Dots through Ligand Modification, Encapsulation, and Interaction with a Superhydrophobic Polymer.

Reducing the detachment of ligands on all-inorganic cesium lead bromide perovskite quantum dots (CsPbBr PQDs) presents a significant challenge to their practical applications, despite their remarkable optoelectronic properties. Herein, a novel strategy was introduced to passivate the surface defects of CsPbBr PQDs by employing short-chain surface ligands and functional groups within a polymer matrix to enhance their processability. Guanidinopropanoic acid (GPA) was employed as a coligand alongside oleic acid and oleylamine to synthesize CsPbBr-GPA PQDs via the hot injection method.

The number of "turn-on" fluorescent probes for Cu is relatively limited, and interference from other metal cations presents a significant challenge for these sensors. In this study, we synthesized and characterized a rhodamine B-based sensor, designated as RBHP, using 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (PMBP) and rhodamine B hydrazide. Selectivity, sensitivity, solvent effects, water content, and pH of RBHP in relation to Cu²⁺ were conducted.

Methylammonium Cation-Regulated Controllable Preparation of CsPbBr Perovskite Quantum Dots in Polystyrene Fiber with Enhanced Water and UV Light Stabilities.

In situ fabrication of lead halide perovskite quantum dots (PQDs) is important for narrow-band emitters for LED displays due to the simple work procedure and convenient usability; however, the growth of PQDs is not readily controllable in the preparation, resulting in low quantum efficiency and environmental instability of PQDs. Here, we demonstrate an effective strategy to controllably prepare CsPbBr PQDs in polystyrene (PS) under the regulation of methylammonium bromide (MABr) via electrostatic spinning and thermal annealing techniques. MA slowed down the growth of CsPbBr PQDs and acted as a surface defect passivation reagent, which was proved by Gibbs free energy simulation, static fluorescence spectra, transmission electron microscopy, and time-resolved photoluminescence (PL) decay spectra.

At present, though calcium (Ca) reagents with high calcium contents are widely synthesized, their wide application is limited due to their low absorption rates and poor bioavailability. Here we use a carboxymethyl cellulose (CMC) derivative with high water solubility and biocompatibility as a ligand to bind Ca2+. The resulting CaCMC complex exhibits remarkable solubility and absorbability under both basic and acidic conditions as well as in stomach mimicking and the gastrointestinal tract.

Currently, nanomaterials with peroxidase activity have become an important colorimetric tool for biomolecular detection. However, compared with natural enzymes, the efficiency of most nanozymes is still lower.

Reversible Response of Luminescent Terbium(III)-Nanocellulose Hydrogels to Anions for Latent Fingerprint Detection and Encryption.

Fingerprint fluorescence imaging has become one of the most prominent technologies in the field of forensic medicine, but it seldom considers the security protection of detection information, which is of great importance in modern society. Herein we demonstrate that luminescent Tb -carboxymethyl cellulose (CMC) complex binding aptamer hydrogels that are reversibly responsive to ClO /SCN can be used for the selective detection, protection, and storage of fingerprint information. The imaging information of the fingerprint can be quenched and recovered by ClO /SCN regulation, respectively, resulting in reversible on/off conversion of the luminescence signals for the encryption and decryption of multiple levels of information.
