Summary: The major challenges in current cancer chemotherapy, including drug resistance, low efficacy, and non-selectivity, can lead to undesirable side effects. This study presents a solution to these challenges through a dual targeting approach for tumors that overexpress CD44 receptors. A nanoformulation called tHAC-MTX nano assembly, composed of hyaluronic acid (HA) conjugated with methotrexate (MTX) and complexed with a thermoresponsive polymer 6-O-carboxymethylchitosan (6-OCMC) graft poly(N-isopropylacrylamide) [6-OCMC-g-PNIPAAm], was developed. The nano assembly exhibited faster drug release at higher temperatures of tumor tissues and enhanced drug release in the presence of hyaluronidase enzyme. The nanoparticles also showed higher cellular uptake and cytotoxicity in cancer cells that overexpress CD44 receptors, suggesting a receptor binding and cellular uptake mechanism. Such multi-targeting nano-assemblies have the potential to improve the efficacy and reduce the side effects of cancer chemotherapy.

Summary: In this experimental work, the EPR signal intensity of hydroxyapatite (HAP) samples was studied from a dosimetric standpoint. HAP samples were prepared in different ways and irradiated with various absorbed doses. The EPR signal intensity of the samples was tested in air at room temperature, showing a linear relationship with dose up to 10 kGy. The findings highlight the importance of fabrication procedure, particle size, carbon impurity, and morphology in determining the EPR signal intensity, with a sample having a grain size of approximately 30 nm and a carbon impurity of 0.47% exhibiting the highest EPR signal intensity with dose.

Summary: The objective of this study was to develop HAp particles for targeted delivery of honokiol to tumor sites after glioma surgical management. Honokiol is released from the HAp-honokiol particles inside cancer cells through endocytosis and acid lysosomal dissolution. HAp-honokiol treatment showed sustained drug release without compromising drug efficacy, leading to a significant reduction in tumor size in a mouse glioma model. These findings suggest that HAp-honokiol particles have potential as an effective drug delivery system for glioma treatment.

Summary: Direct photocatalytic oxidation of methane to liquid oxygenated products at room temperature is achieved using atomically dispersed nickel anchored on a nitrogen-doped carbon/TiO2 composite (Ni-NC/TiO2) catalyst. The Ni-NC/TiO2 catalyst exhibits high activity and selectivity for the formation of Cl oxygenates, with a yield of 198 umol and a selectivity of 93% in 4 hours. The enhanced performance is attributed to the presence of single-atom Ni-NC sites that facilitate electron transfer and activate O2 to form reactive oxygen species.

Summary: The traditional process of synthetic nitrogen-fixing ammonia is energy-consuming and environmentally unfriendly. Therefore, exploring new methods for ammonia synthesis under mild conditions is crucial. Photocatalytic nitrogen fixation utilizes solar energy as an energy source to convert nitrogen to ammonia through photocatalysis at normal temperatures. In recent years, the development of highly efficient photocatalysts has been a hot topic. This study mainly discusses the structure and design of photocatalytic nitrogen-fixing materials, such as introducing vacancies, conducting element doping, and constructing heterojunctions. The study also introduces the oxidation process of N-2 to nitrogen compounds, providing inspiration for the research and development of nitrogen-fixing photocatalysts.
