Summary: This study investigates the possible mechanism of doxorubicin-mediated cardiotoxicity and explores the use of chitosan nanoparticles conjugated with doxorubicin and supplemented with propionic acid to reduce the cardiotoxicity. The results show that DCNPs and propionic acid have a protective effect against doxorubicin-induced cardiotoxicity.

Summary: Selective delivery of high dosage of doxorubicin to the lung was achieved through the use of hollow microcapsules. The microcapsules were non-toxic, compatible with red blood cells, and did not affect blood coagulation time. PET-CT images showed that the majority of the loaded drug was delivered to the lungs and sustainably released.

Summary: Natural antimicrobial peptides (AMPs) are a promising source for new antimicrobial agents, but their clinical application is limited by poor bioavailability and toxicity. This study addresses these limitations by designing a new series of chitosan derivatives that mimic the structure of AMPs, with one derivative showing the most potent antimicrobial activity against Gram-negative bacteria while causing minimal cell death in tested cell lines. The results confirm the importance of cationicity and lipophilicity for selective bacteria targeting with the potential for chitosan nanoparticles as a new class of AMPs mimics effective against Gram-negative bacteria.

Summary: In this study, L-Cysteine-coated magnetic iron oxide nanoparticles loaded with doxorubicin were synthesized and extensively characterized. The binding of doxorubicin to L-Cysteine was confirmed, and the internalization of the nanoparticles delivering doxorubicin was observed in melanoma cells. The nanoparticles also modulated cell signaling pathway activity, induced cell cycle arrest and apoptosis, and exhibited pH-dependent drug release. These results demonstrate the potential of the nanoparticles as efficient drug delivery vehicles in melanoma therapy.

Summary: A high-performance carrageenan/ZnO/chitosan composite film (F-CA/ZnO/CS) was fabricated using solution/dispersion casting and layer-by-layer methods. The film exhibited enhanced mechanical strength, transparency, and decreased water vapor transmission compared to carrageenan film (F-CA) and carrageenan/ZnO composite film (F-CA/ZnO). The addition of ZnO and CS also improved the antibacterial activity against Escherichia coli and Staphylococcus aureus. F-CA/ZnO/CS has the potential to be used in food packaging, wound dressings, and antimicrobial coatings.

Summary: Chitosan and pea protein isolate were used to prepare nanoparticles and their structures and functional properties were evaluated. The particle size and interface properties of the nanoparticles varied with different ratios, and the emulsifying activity was affected by the proportion of protein. The nanoparticles with a ratio of 1:1 showed the highest potential and the best thermal stability, while those with a ratio of 1:3 displayed a spherical morphology.

Summary: This study aimed to investigate the loading of sildenafil citrate in three commercial transdermal vehicles using 3D full-thickness skin equivalent and compare the results with permeability experiments using porcine skin. The results showed that the results obtained using the 3D skin equivalent were comparable to those obtained using porcine skin, suggesting that the 3D skin model can be a valid alternative for ex-vivo skin absorption experiments.
