LIFs-Based Fluorescent Analysis of Silver Ions in Water Using AIEgen-Embedded PVA Hydrogel.

The detection and quantification analysis of silver ions is important to protect human health and improve the level of wastewater treatment. In this work, a polyvinyl alcohol (PVA) hydrogel-based sensing material based on an aggregation-induced emission strategy was developed and combined with a portable laser-induced fluorescence spectroscopy (LIFs) device for the direct detection and quantification of silver ions in water. Considering the requirements of environmental water analysis regarding portability, reliability, and convenience, this fluorescence turn-on strategy was optimized accordingly to ensure the accuracy and stability of the analysis in complex natural water environmental.

Effective extraction of Xuetongsu and its role in preventing RA synovial hyperplasia by targeting synovial cell migration and apoptosis.

Kadsura heteroclita (Roxb) Craib also named Xuetong in Tujia ethnomedicine in China, has been traditionally employed in rheumatoid arthritis (RA) treatment. Our preceding investigations have elucidated that Xuetongsu (XTS), a triterpenoid compound predominant in Xuetong, showed excellent anti-RA-fibroblast-like synoviocytes (RAFLS) proliferation effect. However, XTS belongs to the trace components of the Xuetong plant, which poses certain limitations to the research.

Kadsura heteroclita (Roxb) Craib, also called Xuetong in Chinese Tujia ethnomedicine, is utilized for its medicinal properties, including promoting blood circulation, dispelling "wind evil", and relieving "damp evil". It has been used in the treatment of arthralgia and RA, within Tujia ethnomedicinal practices.

[MMPs/pH synergically responsive XTS-Prussian blue nanoparticles inhibiting proliferation and migration of RAFLS assisted with laser irradiation].

Rheumatoid arthritis(RA) is a condition in which the joints are in a weakly acidic environment. In RA, RA fibroblastlike synoviocytes( RAFLS) in the joints become abnormally activated and secrete a large amount of matrix metalloproteinases(MMPs), and the receptor protein CD44 on the cell membrane is specifically upregulated. Xuetongsu(XTS), an active ingredient in the Tujia ethnomedicine Xuetong, is known to inhibit the proliferation of RAFLS.

Fluorogenic in-situ Labelling of Gelatin Polymer in Aqueous Solution and Hydrogel.

Gelatin polymers made from partially degraded collagen are important biomaterials, but their in-situ analysis suffers from uncontrollable covalent labelling and poor spatial-temporal imaging resolution. Herein, three tetrazolate-tagged tetraphenylethylene fluorophores (TPE-TAs) are introduced for practical fluorogenic labelling of gelatin in aqueous phase and hydrogels. These probes with aggregation-induced emission characteristics offer negligible background and elicit turn-on fluorescence by simply mixing with the gelatin in aqueous phase, giving a detection limit of 0.

Recent advances of NFATc1 in rheumatoid arthritis-related bone destruction: mechanisms and potential therapeutic targets.

Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease characterized by inflammation of the synovial tissue and joint bone destruction, often leading to significant disability. The main pathological manifestation of joint deformity in RA patients is bone destruction, which occurs due to the differentiation and proliferation of osteoclasts. The transcription factor nuclear factor-activated T cell 1 (NFATc1) plays a crucial role in this process.
