Herein, biogenic silver nanoparticles, Cafi-AgNPs was produced based on Cassia fistula-phenolic-rich extract (Cafi) only, without any toxic chemical reagent or organic solvent. Cafi bioactives were characterized using UHPLC-ESI-QTOF-MS/MS analysis. The as-synthesized nanoparticles were characterized using physico-chemical techniques including UV-vis, TEM, SEM, EDX, FTIR, DLS, Zeta potential, XRD, TGA and DGA. In addition, their antioxidant properties and cytocompatibility on erythrocytes and HEK-293 cells were examined. Results show that Cafi mediated the successful synthesis of stable well-dispersed AgNPs. Cafi-AgNPs demonstrated potent reducing and radical scavenging activities against ABTS˙, DPPH˙ and NO˙. Furthermore, Cafi-AgNPs was compatible with human erythrocytes and HEK-293 cells. Based on the superior surface plasmonic and biological attributes of Cafi-AgNPs, its potential in HO sensing was evaluated. The proposed sensor demonstrated satisfactory analytical performances with linearity of 10-200 μM, detection limit of 3.0 μM for HO and was successfully applied in the detection of HO in human plasma.

Natural plant-derived polysaccharides exhibit substantial potential for treating ulcerative colitis (UC) owing to their anti-inflammatory and antioxidant properties and favorable safety profiles. However, their practical application faces several challenges, including structural instability in gastric acid, imprecise targeting of inflamed regions, and limited intestinal retention times. To address these limitations, pH-responsive, colon-targeting microspheres (pWGPAC MSs) are developed for delivering phosphorylated wild ginseng polysaccharides (pWGP) to alleviate UC.

Background: Atherosclerosis, a persistent inflammatory disease marked by the presence of atherosclerotic plaques or fibrous plaques, is a significant contributor to the onset of the development of cardiovascular disease. Berk contains various active ingredients that have anti-inflammatory, antioxidant, and hypolipidemic properties. Nevertheless, the potential effects of on atherosclerosis have not been systematically reported.

Background: Oxaliplatin-induced neuropathy (OIN) is a severe painful condition that strongly affects the patient's quality of life and cannot be counteracted by the available drugs or adjuvants. Thus, several efforts are devoted to discovering substances that can revert or reduce OIN, including natural compounds. The carob tree, L.

Flavonoids are naturally occurring polyphenolic compounds known for their extensive range of biological activities. This review focuses on the inhibitory effects of flavonoids on acetylcholinesterase (AChE) and their potential as therapeutic agents for cognitive dysfunction. AChE, a serine hydrolase that plays a crucial role in cholinergic neurotransmission, is a key target in the treatment of cognitive impairments due to its function in acetylcholine hydrolysis.
