Surface-modified carbon quantum dot for enhanced fluorescent-sensing of hexagonal valent chromium.

As one of the most harmful heavy metal pollutants, hexavalent chromium Cr(VI) is becoming a serious threat to human health. Thus pursuing a remarkably sensitive method to monitor the Cr(VI) concentration in natural conditions is favored for the fast response to prevent harm. In the present work, an ethylenediamine (En) and SiO-modified wool keratin-based carbon quantum dot (CQD)(En@CQDs@SiO) fluorescent sensor is prepared, and the En is found to improve the discrimination ability by binding the Cr(VI) with the surface carboxyl groups.

Compositional Differences of Various Sorption States of Cu and Cd on Goethite in the Presence of Oxyanions: A Quantitative Study.

The anionic species of antimony(V) and phosphate(V) are commonly found in the contaminated soil of mining areas, exerting a significant influence on the sorption of heavy metals and thus affecting their migration. This study quantitatively discussed the sorption mechanism of Sb and P in promoting the sorption of Cd or Cu on goethite through a series of extraction methods. In the single sorption system, the majority of Cu (87-98%) is adsorbed on goethite in the form of EDTA-extractable Cu (EF Cu, possibly inner-sphere complexes) under pH conditions of 3.

Cianidanol from Sea Buckthorn Exert Anti-Inflammatory Effects by the Inhibiting JAK2/STAT3 Signaling Pathway via an Integrative Pharmacology Strategy.

Sea buckthorn is a model of medicine and food homology, but the chemical composition and mechanism of anti-inflammatory effects are limited. In this study, the key components and mechanisms of the anti-inflammatory effects of sea buckthorn were identified based on UPLC-Q-TOF-MS, network pharmacology, molecular docking, molecular dynamics and RAW264.7 cells.

Phoenixin's Influence on HPG Axis and Inflammation in Elite Ice Hockey Athletes: A Cross-Sectional Analysis.

The neuropeptide phoenixin (PNX) may be involved in regulating the hypothalamic-pituitary-gonadal (HPG) axis and inflammatory responses. This study aims to investigate the role of PNX in the regulation of HPG axis function in ice hockey players and its impact on body composition. This cross-sectional study included 65 male ice hockey players aged 18-22, divided into untrained, non-elite athlete, and elite athlete groups.
