Summary: Melatonin (MT) is a plant hormone that protects plants from adverse environmental conditions. This study analyzed the responses of Wolffia arrhiza exposed to cadmium (Cd) and MT. The levels of MT and its precursors were higher in plants exposed to Cd, and the application of MT and Cd intensified their biosynthesis. MT enhanced the growth and content of pigments, protein, and sugars, while Cd treatment decreased these compounds, which were mitigated by MT. Cd increased stress markers, while MT reduced their content in duckweed exposed to Cd. In summary, MT is an essential phytohormone for plant growth and development, especially during heavy metal stress.

Summary: Brassinolide and Brassinazole have concentration-dependent effects on the growth and biosynthesis of Wolffia arrhiza, with 0.1 mu M Brassinolide showing the most stimulatory effects on growth and levels of various compounds in the plant. Meanwhile, 1 mu M and 10 mu M Brassinazole caused significant decreases in duckweed weight and targeted compound levels. Moreover, Brassinolide mitigated the inhibitory effect of Brassinazole and enhanced the BR level in duckweed treated with Brassinazole for the first time.

Summary: The study successfully transformed 8550 explants with Agrobacterium, resulting in 41 hygromycin-resistant Wolffia lines with a transformation efficiency of 0.48%. 40 of these lines expressed the hirudin-1 gene, with the maximum accumulation of recombinant hirudin being 0.02% of total soluble protein. The results will be used for developing an expression system based on Wolffia plants for producing hirudin and other recombinant pharmaceutical proteins.

Summary: This study conducted a comprehensive investigation of the morphology and anatomy of Wolffia globosa, the only Wolffia species in China. It revealed that the reproductive strategy of W. globosa plants allows for rapid biomass accumulation and widespread distribution in various habitats. The reduced body plan and limited cell types in Wolffia plants make them suitable for studying structural reduction in higher plants and exploring fundamental developmental processes that cannot be addressed using other model plants.

Summary: This study investigated the physical changes induced by drying treatments, such as protein denaturation, cell membrane integrity, and viscoelastic relaxation, as possible causes of the variation in moisture sorption isotherms (MSIs) and hysteresis. Experimental and theoretical evaluations of MSIs were conducted. The Flory-Huggins theory analysis concluded that protein denaturation does not significantly affect moisture sorption and hysteresis. Cell membrane integrity only influences moisture sorption at high relative humidity. Additional experiments showed that mushrooms exhibit temperature and moisture-dependent viscoelastic properties, and viscoelastic relaxation is likely the determining factor affecting the variations in MSI and hysteresis.

Summary: The effect of dried jackfruit powder on the extrusion of cornmeal was studied to create a naturally flavored and nutritious expanded snack. Both ripe and unripe jackfruit powder were added to corn grits to investigate the impact of macronutrient composition, feed composition and particle size on extrusion parameters. The addition of jackfruit hindered the expansion ratio of the extrudate, with ripe jackfruit increasing sugar content and unripe jackfruit increasing fiber content. Ripe jackfruit also had higher moisture sorption, resulting in a higher water solubility index of the extrudate. The starch-sugar-fiber composition had a larger effect on expansion than feed particle size.

Summary: Phosphorus-induced eutrophication of freshwaters is a great global challenge that requires the development of phosphate sorbents with high affinity and selectivity. Introduction of lanthanum into the structure of single sheet iron oxide improves phosphate sorption affinity and selectivity. The resulting La-SSIs show fast phosphate sorption, high stability, and high selectivity for phosphate, making them a promising sorbent for treating low-phosphate yet eutrophying natural waters.

Summary: The study investigated sorption isotherms of sorbitol osmotically pre-treated cambuci slices at different temperatures with the DDI method, finding that the fruits exhibited hydrophobic behavior at low water activities and the pre-treatment acted as a humidifier. Results showed that relative humidity, pre-treatment, and temperature significantly influenced the equilibrium moisture content, with X-eq decreasing at lower relative humidity, while the isosteric heat of sorption reinforced the water-binding property of sorbitol.

Summary: This study proposes a methodology to predict water-sorption isotherms and kinetics in amorphous pharmaceutical formulations. The validity of this approach was verified through experiments on polyvinylpyrrolidone-based polymers and indomethacin. The accurate prediction of water-sorption isotherms was achieved by combining PC-SAFT with NET-GP approach.

Summary: This study investigated the role of autophagy-related proteins in the infection of epithelial cells by Candida albicans. The results showed that autophagy-related proteins were recruited to invasion sites and autophagosomes were formed during active penetration of C. albicans into host cells. These autophagic events were associated with plasma membrane damage. Additionally, the autophagy-related proteins ATG5 and ATG16L1 played a crucial role in maintaining plasma membrane repair and protecting epithelial cells against C. albicans-induced cell death.

Summary: This study fills the research gap in designing drying and storage conditions for red water lily petals, and provides insights into sorption isotherms and factors affecting quality changes during storage. The GAB model accurately describes the sorption isotherm, while the Blahovec-Yanniotis model explains the contribution of water in both adsorption and desorption processes. Storage time and relative humidity play a crucial role in quality changes, and the correlation between color parameters and antioxidant capacities can be used as a nondestructive analytical technique.

Summary: The global market value of snack foods increases annually. However, overconsumption of snack foods, especially junk foods causes various health problems. Healthy snacks are considered as alternative choices. Banana is used for healthy snack production due to its health-promoting compounds. In this study, different pre-frying treatments were proposed to reduce oil content in banana chips. Quality parameters were assessed and principal component analysis (PCA) was used to select the most appropriate treatment. The results showed that MRF was the most suitable method with a 40% reduction in oil absorption.
