Summary: The extraction of lutein from marigold petals using a surfactant-based aqueous two-phase system is reported. The effectiveness of the hydrophilic-lipophilic balance of surfactants on extraction performance for lutein extraction is demonstrated. Optimized conditions for maximum lutein extraction are obtained (Temperature = 37.5 degrees C, S/L = 0.00375, and surfactant amount = 1.5% (v/v)), and the obtained lutein extract shows higher antioxidant activity compared to extracts obtained by organic solvents.

Summary: The study found that lutein dipalmitate could spontaneously bind to ovalbumin via van der Waals force and hydrogen bond, leading to conformational changes in ovalbumin and promoting its aggregation. Additionally, ovalbumin had a positive effect on the stability of marigold lutein esters extracts.

Summary: Despite the lack of research on the facilitation of positive emotions by classroom teachers during emergency remote teaching (ERT), this study interviewed 18 university English teachers in Hong Kong to identify the strategies they used during the ERT period. The results show that the constructionist approach, a traditional learning theory, played an unexpectedly important role in promoting positive student emotions and encouraging learning. Cognitive demanding tasks helped divert students' attention from negative emotions and interactions also played an essential role in reducing negative emotions and facilitating learning.

Summary: This research investigates the impact of foliar polyamine spray on the growth, photosynthetic indices, secondary metabolites, and antioxidant activity of pot marigold. The results show that polyamine spray, especially spermidine, significantly enhances morphological and photosynthetic parameters, increases total oil and phenolic/flavonoid content, and improves antioxidant capacity. Additionally, polyamine application increases the abundance of sesquiterpene hydrocarbons in essential oils and carotenoids in flowers, indicating potential applications in the pharmaceutical industry.

Summary: The study revealed that the addition of marigold powder had certain effects on the pasting properties of wheat flour and the quality of noodles, but did not cause negative impacts at a certain level. After cooking, the lutein content in the noodles decreased, but still met the recommended daily intake, and adding marigold powder enhanced the antioxidant properties of the noodles.

Summary: Carotenoids from locally adapted and organically grown cereal genotypes showed large variations in content and composition, with different dominant types in wheat, rye, and barley. High-level genotypes exhibited high carotenoid values, while barley genotypes demonstrated relatively high stability. The local adaptation of the evaluated cereal genotypes provides opportunities for local production of high value, highly nutritious food products.

Summary: Spinel-type porous Co0.7Zn0.3Fe1.7Ni0.3O4 mesoporous flower-like microspheres were synthesized using a hydrothermal technique. The microspheres exhibited interconnected porous nano lamella and an increase in lattice constants due to Zn and Fe substitution. The electrochemical sensor showed excellent sensitivity and reproducibility towards glucose, with a 92% response and low interference from other substances.

Summary: This study aimed to investigate and optimize the quality and sensory properties of baked products with lutein-enriched marigold flower powder (MP). Different particle sizes of MP were added to sponge cakes, with superfine MP showing the highest lutein content and sensory acceptance. The results suggest that jet milling can improve the texture, lutein content, and sensory qualities of baked products with MP.

Summary: This study proposed a method for the remediation of diesel-contaminated soil (DCS) using alkoxyethanol aqueous two-phase extraction (ATPE), with high efficiency in removing diesel and high reusability. The process hardly caused residual organic solvents on the soil surface, and the soil structure and properties remained relatively unchanged after remediation.

Summary: A novel method for fabricating drug-preloaded gelatin microspheres (GMS) using a water-in-water emulsification technique was developed. The drug-loaded GMS showed improved stability, drug-loading efficiency, and sustained release compared to conventional GMS. Incorporation of the drug-loaded GMS into multicellular spheroids enhanced cell viability and improved therapeutic efficacy in a wound healing mouse model.
