Summary: The adverse effects of modern fungicide consumption have led to problems in the agroecosystem, making it important to research alternatives. The use of herbal extracts containing secondary metabolites has become a trend in sustainable agriculture. However, issues arise due to poor solubility and volatility, which can be addressed through the use of nano- or micro-particles for bioactive compound delivery. In this study, the potential of Vernonia amygdalina EtOAc extract and microspheres loaded with the extract to inhibit Phytophthora palmivora growth was evaluated, with the microspheres showing significant improvement compared to the direct usage of the extract.

Summary: In this study, the extraction, purification, and biochemical properties of polyphenol oxidase (PPO) from bitter leaf were investigated. The enzyme showed diphenolase activity and exhibited preference for catechol as a substrate. The optimum pH and temperature for the enzyme were 5.5 and 50 degrees C, respectively. Metal ions such as Na+, K+, and Ba2+ activated the enzyme, while Cu2+ and NH4+ inhibited its activity. The vaPPO demonstrated stability in the presence of organic solvents and high temperatures, making it suitable for biotechnological applications.

Summary: The neuroprotective effect of betulinic acid against oxidative neurotoxicity induced by iron was investigated in isolated rat brains. The induction of oxidative neurotoxicity resulted in suppressed antioxidant levels and increased levels of reactive oxygen species. Treatment with betulinic acid reversed these effects and restored the depleted compounds. Pathway analysis revealed the activation of neuroprotective metabolic pathways upon betulinic acid treatment. Molecular docking showed a strong binding affinity between betulinic acid and ATPase. These findings suggest that betulinic acid confers neuroprotection by restoring redox balance and modulating various metabolic pathways.
