CRISPR-Based Enhancement of Secondary Metabolites in Artemisia annua: Focus on Artemisinin Biosynthesis
Abstract: Medicinal plants are natural biofactories producing secondary metabolites with significant therapeutic value, including terpenoids, alkaloids, and phenolics. Among these, artemisinin, a sesquiterpene lactone from Artemisia annua L. is the cornerstone of global antimalarial therapy along with additional anticancer, antiviral, and antimicrobial activities. However, artemisinin content in the native plants is inherently low (typically 0.01–0.8% dry weight), restricting affordable and consistent supply. Conventional approaches to increase production include classical breeding, singlegene …

Effect of Polymer Crosslinking on Drug Release Kinetics
Abstract: In order to improve treatment effectiveness and minimise adverse effects, polymer-based drug delivery systems are often used to produce regulated and sustained drug release. Polymer crosslinking, which alters the structural, mechanical, and degrading characteristics of the polymer matrix, is one of the key elements affecting drug release kinetics. The porosity, swelling behaviour, and rate of degradation of the polymer are all impacted by the crosslinking process, which may be accomplished …
