Summary: The investigation on the functionalization process of quantum dots (QDs) using transferrin is very essential due to the high importance of transferrin in targeting tumor. The study found that both CdSe and CdSe@ZnS QDs triggered the fluorescence quenching of transferrin by the static quenching mechanism. The binding constant for CdSe@ZnS QDs was higher than CdSe QDs, indicating a stronger binding between CdSe@ZnS QDs and transferrin. The interaction between QDs and transferrin resulted in conformational changes of the latter and the release of iron ions from transferrin.

Summary: An efficient and stable fluorescent probe for Al3+ based on the fluorescence 'turn-on' mode of zinc sulfide crystal composite zinc oxide quantum dots (ZnS/ZnO QDs) was established in this work. The synthesized ZnS/ZnO QDs showed fluorescent enhancement to Al3+ and presented wide linear ranges for detection. The mechanism of fluorescence enhancement was related to the QDs dispersion and charge transfer weaken, as determined by recording the fluorescent lifetime of samples.

Summary: This study demonstrates the synthesis and photocatalytic performance of ZnS-ZnO composites with different compositions of ZnS-c, ZnS-h, and ZnO phases for H2 production. The solvothermal method was used to partially sulfide ZnO at different temperatures (150°C, 200°C, and 250°C) using mono ethylene glycol and thiourea as solvent and sulfur source, respectively. The material characterization involved X-ray diffraction, electron microscopy, UV-visible spectroscopy, X-ray photoelectron microscopy, N2 adsorption-desorption isotherms, and photoelectrochemical techniques. The highest photoactive material was synthesized at 200°C, showing an H2 production rate of 580 µmol h-1 g-1, attributed to the optimized interfacial properties between ZnS-c/ZnS-h and ZnO in the coupled photocatalytic system.

Summary: In this study, a blend of polyvinyl alcohol (PVA) and carboxymethyl cellulose (CMC) loaded with different ratios of zinc sulfide quantum dots (ZnS QDs) was prepared using thermolysis and casting methods. The nano nature of the powder filler was examined using X-ray diffraction analysis, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The optical features of the PVA/CMC blend were investigated using UV-vis diffuse reflectance spectroscopy. The results showed that increasing the loading ratio of ZnS QDs significantly affected the optical properties of the blend, providing the possibility for tuning the band gap, refractive index, and optical conductivity. The present materials have the potential for a wide range of applications in optoelectronics, coatings, and lenses.

Summary: Mixture design is a statistical tool that optimizes the composition of a mixture using a minimum number of experiments. In this study, a simplex-lattice mixture design method was used to optimize the composition of a mixture of essential oils from basil, citronella, cedarwood, and thyme. The optimized parameter was the antioxidant activity, and the test results showed a synergistic effect between the components of essential oils. The designed mixture with the highest antioxidant activity consisted of 54.4% citronella essential oil, 33.0% thyme essential oil, 9.2% cedarwood essential oil, and 3.4% basil essential oil.

Summary: This article systematically reviews the anti-blood stasis effects of the bioactive components of Salvia miltiorrhiza (SM), focusing on their molecular mechanisms. Phenolic acids and tanshinones in SM are the main bioactive components that protect vascular endothelial cells, regulate blood coagulation and fibrinolysis, inhibit platelet activation, and dilate blood vessels. The underlying mechanisms involve multiple signaling pathways such as Nrf2/HO-1, TLR4/MyD88/NF-kappaB, PI3K/Akt/eNOS, MAPKs, and Ca2+/K+ channels.

Summary: This study investigated the vasoprotective effects of apigenin and its underlying mechanisms in endothelial dysfunction associated with diabetes. The results showed that apigenin improved endothelial function and reduced oxidative stress through the activation of AMPK/PI3K/Akt/eNOS and Nrf2/HO-1 pathways. These findings suggest the therapeutic potential of apigenin as a natural dietary flavonoid against vascular diseases associated with diabetes.
