Regulation of Cbfa1 Expression by Total Flavonoids of Herba Epimedii

open access: yesEndocrine Journal, 2006
Core binding factor alpha1 (Cbfa1) is a member of the runt family of transcription factors, which appears to play a pivotal role in regulating the differentiation of osteoblastic precursors and the activity of mature osteoblasts. Total flavonoids of Herba epimedii (HEF) is a recognized bone anabolic agent, but there is lack of reports on the modulation

Aloe vera–Based Green Synthesis of Silver Nanoparticles With Characterization, Potent Antibacterial and Antioxidant Properties

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Green synthesis has emerged as a suitable alternative to the traditional method for manufacturing nanoparticles (NPs) as it provides a safer, sustainable, healthy, and environmental path for the NPs synthesis. Silver nanoparticles (AgNPs) were prepared using a green method with locally sourced Aloe vera leaf extract.

Synthesis and Characterization of Ag–Fe Bimetallic Nanoparticles and Nanocomposites (Alloys and Core–Shells) for Photocatalytic Degradation of Bromophenol Blue Dye Using Grewia optiva Leaf Extract

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Ag–Fe bimetallic nanoparticles (alloy and core–shell structures) were synthesized using Grewia optiva leaf extract through a green, phytochemical‐mediated approach. The effects of pH, temperature, extract concentration, and Ag:Fe molar ratio on nanoparticle formation were systematically optimized, enabling size‐controlled and morphologically ...
