In the present work, two downstream processes - high-pressure homogenization at 100 (HPH-100) and 1200 bar (HPH-1200), and enzymatic hydrolysis (EH) - were tested to produce biostimulant extracts from Tetradesmus obliquus grown in piggery wastewater at two concentrations (12.8 and 88.3 g/L). Extracts before and after centrifugation (C) were evaluated in four bioassays using garden cress (germination), mung bean (auxin-like activity), and cucumber (auxin- and cytokinin-like activity) relative to distilled water. The initial microalgal culture, without any treatment, had the best germination results (162 % at 0.2 g/L) and the only one that showed cytokinin-like activity (141 % at 0.5 g/L). In both auxin-like bioassays, the HPH-1200 + C and EH + C originated high values (186 and 155 % for cucumber, 290 and 285 % for mung bean, respectively). For mung bean, the HPH-1200 achieved the highest auxin-like effect (378 %). Finally, the extracted biomass contained essential nutrients for biofertilization, complementing the biostimulant extracts for sustainable agriculture application.

Mung bean hull polyphenols (MBPs) have the potential to retard starch digestion by altering its multi-scale structures. However, the regulatory mechanism and the key structural characteristics that contribute to digestion resistance remain unclear. In this study, MBPs were non-covalently interacted with wheat starch (WS) under hydrothermal treatments.

Background And Aims: Homozygous familial hypercholesterolemia (HoFH) is a hereditary lipid metabolism disorder characterized by severe elevation of low-density lipoprotein cholesterol (LDL-C) and heightened risk of premature atherosclerotic cardiovascular disease (ASCVD). Lomitapide, an inhibitor of microsomal triglyceride transfer protein, has shown promise in reducing LDL-C levels, albeit with variable response in real-world settings. Sex-based differences in treatment efficacy and safety remain unclear.

The widespread use of nanoparticles raises substantial environmental, health, and safety issues. The specific mechanisms by which they impact plants and animals, as well as the entire scope of their possible impact, are still unknown. The current work investigates the impact of varying CuO NPs concentrations on phytotoxicity, cytotoxicity, genotoxicity, and antioxidant activity.

Pathogen-carrying seeds can significantly impact plant growth and development and may lead to serious public health incidents. Modern agriculture heavily relies on synthetic chemical microbicides and physical methods to eradicate pathogens transmitted by plant seeds. To counteract the misuse of microbicides, a class of cationic amphiphilic aggregate-induced emission luminogens (AIEgens) are developed as photodynamic seed sterilization agents.

Diet digestibility can vary based on factors such as the type of ingredients, processing techniques, formulation, fiber content, and nutrient interactions. Unlike proteins and fats, there is no specific carbohydrate requirement, which typically constitutes 30%-60% of commercial dried dog foods. Because of the significant proportion of carbohydrates in dog food, this study aimed to evaluate the differences in nutrient digestibility among barley, brown rice, corn, mung bean, and rice, which are common carbohydrate sources in commercial dog foods.
