Light-Responsive Smart Nanoliposomes: Harnessing the Azobenzene Moiety for Controlled Drug Release under Near-Infrared Irradiation.

The azobenzene moiety is an intriguing structure that deforms under UV and visible light, indicating a high potential for biomedical applications. However, its reaction to UV radiation is problematic because of its high energy and low tissue penetration. Unlike previous research on azobenzene structures in photoresponsive materials, this study presents a novel method for imparting photostimulation-responsive properties to liposomes by incorporating the azobenzene moiety and extending the light wavelength with up-conversion nanoparticles.

A novel CT-responsive hydrogel for the construction of an organ simulation phantom for the repeatability and stability study of radiomic features.

Radiomic features have demonstrated reliable outcomes in tumor grading and detecting precancerous lesions in medical imaging analysis. However, the repeatability and stability of these features have faced criticism. In this study, we aim to enhance the repeatability and stability of radiomic features by introducing a novel CT-responsive hydrogel material.

Simply and Cheaply Prepared Liposomal Membrane for Nanocarriers: High Encapsulation Efficiency Based on Broad Regulation of Surface Charges and pH-Switchable Performance.

The zeta potential of nanoparticles impacts their distribution and metabolism in the body as well as their interaction with medications of varying charges, hence altering therapeutic efficacy and safety. In this paper, the external charges of liposomes were regulated by utilizing a simple and economical method based on competition for protons of cationic chitosan (CS) and anion hyaluronic acid (HA). The charge regulation of a liposomal membrane is generally accomplished by adjusting the ratio of charged lipids within a liposome (e.

Tree peony transcription factor PrWRI1 enhances seed oil accumulation.

Background: WRINKLED1 (WRI1) encodes a transcription factor, belonging to the APETALA2 (AP2) family, and plays a key role in regulating plant oil biosynthesis. As a newly woody oil crop, tree peony (Paeonia rockii) was notable for the abundant unsaturated fatty acids in its seed oil. However, the role of WRI1 during the accumulation of P.
