The study synthesized Pluronic F-127 coated zinc oxide nanoparticles (PF-127ZnO NPs) using leaf extract and evaluated their antibacterial, antioxidant, and anticancer properties using various characterization methods such as UV-Vis, Fourier Transform Infra-Red, Photoluminescence spectroscopy, FESEM, EDAX, TEM, SAED, XRD, and DLS. The disc diffusion technique was used to evaluate the antibacterial properties of synthesized Pluronic F-127 coated zinc oxide nanoparticles against various pathogens and significant anticancer activity was noticed. The study examined the cytotoxicity of PF127ZnO nanoparticles to Hep3B cells . The cytotoxicity was IC50 at 10 µM concentration. The study examined the biocompatibility of PF-127ZnO NPs, revealing membrane blebbing, chromatin condensation, and stimulation of the proapoptotic protein caspase cascade family. The study reveals that PF-127ZnO NPs, synthesized from leaf extract, exhibit antibacterial and antihepatic properties, offering potential biomedical applications due to their high stability and biocompatibility.

Hyperuricemia-related diabetic wounds are notoriously difficult to treat due to elevated uric acid (UA) levels, excessive reactive oxygen species (ROS), and chronic inflammation. Current therapies often fail to address these underlying causes, underscoring the need for innovative approaches that not only clear UA but also mitigate inflammation and promote tissue regeneration. In this study, we developed a polyrotaxane-based microsphere (HPR MS) system conjugated with 4,5-diamino-2-thiouracil (DT) to achieve high-affinity UA clearance without increasing cytotoxicity.

To design a multifunctional nanozyme hydrogel with antibacterial, photo-responsive nitric oxide-releasing, and antioxidative properties for promoting the healing of infected wounds. We first developed ultra-small silver nanoparticles (NPs)-decorated sodium nitroprusside-doped Prussian blue (SNPB) NPs, referred to as SNPB@Ag NPs, which served as a multifunctional nanozyme. Subsequently, this nanozyme, together with geniposide (GE), was incorporated into a thermo-sensitive hydrogel, formulated from Poloxamer 407 and carboxymethyl chitosan, creating a novel antibacterial wound dressing designated as GE/SNPB@Ag hydrogel.

Background/objectives: A sustained-release formulation of fenofibrate while enhancing drug dissolution with minimal food effect is critical for maximizing the therapeutic benefits of fenofibrate. Therefore, this study aimed to develop an effective solid dispersion formulation of fenofibrate for simultaneous enhancement in the extent and duration of drug exposure.
Methods: Fenofibrate-loaded solid dispersions (FNSDs) were prepared using poloxamer 407 and Eudragit RSPO at varied ratios via solvent evaporation.

Indomethacin (IDM) is commonly used to treat chronic inflammatory diseases such as rheumatoid arthritis and osteoarthritis. However, long-term oral IDM treatment can harm the gastrointestinal tract. This study presents a design for encapsulating IDM within mixed micelles (MMs)-loaded dissolving microneedles (DMNs) to improve and sustain transdermal drug delivery.
