Minimizing quantification uncertainty in nanoplasmonic platforms: Multifunctional MoS2‐integration for precise biomarker determination

InfoMat, EarlyView.
The multifunctional integration of MoS2 into the SERS platform addresses key limitations in accurate quantification. Atomically thin MoS2 reduces spot‐to‐spot variations via plasmonic calibration and improves quantification reliability by ensuring consistent signal changes with analyte concentration.

Effect of ELF e.m. fields on metalloprotein redox-active sites

, 2007
The peculiarity of the distribution and geometry of metallic ions in enzymes pushed us to set the hypothesis that metallic ions in active-site act like tiny antennas able to pick up very feeble e.m. signals.

Effects of catechins, resveratrol, silymarin components and some of their conjugates on xanthine oxidase‐catalyzed xanthine and 6‐mercaptopurine oxidation

Journal of the Science of Food and Agriculture, Volume 105, Issue 5, Page 2765-2776, 30 March 2025.
Abstract BACKGROUND Over the past two decades, the global incidence of gout has markedly increased, affecting people worldwide. Considering the side effects of xanthine oxidase (XO) inhibitor drugs (e.g. allopurinol and febuxostat) used in the treatment of hyperuricemia and gout, the potential application of phytochemicals has been widely studied.

Effect of post‐harvest ultrasound treatment on phytochemical enhancement in Gynura procumbens leaves and their protection against oxidative stress‐induced muscle atrophy

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Gynura procumbens is a medicinal plant widely recognized for its antioxidant and anti‐inflammatory properties. Despite its traditional use in Southeast Asia, its potential role in promoting muscle health has not been thoroughly investigated.

Purine and pyrimidine bases as growth substances for lactic acid bacteria [PDF]

, 1941
In 1936 Richardson (1) showed that uracil was essential for the anaerobic growth of Staphylococcus aureus, but not for aerobic growth of the same organism.
