Summary: Sodium citrate has been found to increase the negative charges on bitumen surfaces, leading to enhanced bitumen liberation and prevention of slime coating. Similar chemicals like EDTA and phosphate also increase the negative charges on bitumen surfaces, while sodium sulfate has the opposite effect. Ligands such as sodium citrate can remove metal ions from bitumen and adsorb onto the bitumen surface, modifying the zeta potential at the bitumen/water interface.

Summary: The optical-electrical properties of CuO-NPs have been widely expanded for high-tech applications. In this study, CuO-NPs were synthesized using a safer and eco-friendly method by stabilizing them with biopolymer sodium hyaluronate (SH). The resulting CuO-NPs exhibited controlled characteristics and were stable, crystalline, and of restricted distribution. The synthesis process was found to be primarily responsible for the formation and stabilization of CuO-NPs through redox reaction and capping effect. Additionally, the SH-stabilized CuO-NPs demonstrated strong bactericidal, anti-diabetic, DNA cleavage, and antioxidant activities, as well as catalytic activity for dye reduction. These findings highlight the potential of CuO-NPs as versatile agents in various biomedical and industrial processes, including wastewater treatment.

Summary: Plasma protein binding plays a crucial role in the pharmacokinetics and pharmacodynamics of therapeutic bioactive materials. In this study, the interaction of nordentatin, a member of coumarins, with human alpha-1 acid glycoprotein (AGP) was investigated, and the anticancer potency of nordentatin against human colorectal cancer cells was evaluated. The results showed that nordentatin binds to AGP through a static quenching mechanism and exhibits inhibitory effects on the growth of HCT-116 cells by increasing intracellular ROS and [Ca2+] levels and triggering apoptosis-related gene overexpression. Therefore, nordentatin could be a promising plant-based therapy for colorectal cancer.
