Dual Action of Reduced Allergenicity and Improved Memory of Instant Soybean Powder Hydrolysates.

Soy allergens are susceptible to inducing allergic reactions in infants and young animals, which have an impact on the effective daily utilization of proteins. In this study, we used Alcalase-hydrolyzed instant soybean powder (ISP) to clarify the sensitization changes of instant soybean powder hydrolysates (ISPH), and we explored the assisted memory-enhancing effects. BALB/c mice in the ISPH group showed significant improvement in the allergy symptoms, with their allergy symptom scores decreasing to (1.57 ± 0.53) and their specific serum IgE and IgG1 binding capacity decreasing by 28.00 and 25.73% (P < 0.05), which suppressed the mast cell degranulation rate. Meanwhile, the plasma HIS and IL-4 levels decreased by 12.59 and 25.32%, and the plasma INF-γ and IL- 10 levels increased by 30.64 and 27.79%, which obviously regulated the imbalance of Th1/Th2 cells and attenuated the tissue damage (P < 0.05). Furthermore, ISPH improved behavioral characteristics, increased cholinergic system activity, reduced neuronal cell damage or apoptosis, and increased the number of Nissl bodies to help improve memory in Kunming mice (P < 0.05). In general, alcalase-hydrolyzed ISP had the dual effects of reducing allergenicity and aiding in memory improvement.

A novel asymmetric CDI device for targeted removal of cation in water desalination.

A novel asymmetric capacitive deionisation (CDI) device was home-made for the removal of cations from an aqueous solution through the structural innovation in this experiment. The adsorbent materials were characterised by Scanning Electron Microscope and BET as well as performing cyclic voltammetry curve tests. The results showed that the materials exhibited excellent performance (the specific surface area is 321.14 m²/g) and the maximum specific capacitance of the adsorbent material can reach 60 F/g at the 5 mV/s. The optimal operating conditions of the asymmetric CDI device were obtained using an orthogonal test method analysis and response surface methodology: the best desalination efficiency of CDI obtained at the concentration is 455.82 mg/L, the potential is 1.18 V and the flow rate is 46.54 mL/min. After the analysis of first-order kinetic model, it can be obtained that the fastest adsorption efficiency for Ca2+, followed by Mg2+, and the slowest for Na+, and the CDI device had a better adsorption effect on divalent cations. Simulation by Comsol software showed that the adsorption efficiency was better at a high flow rate. In addition, the CDI device has good stability and the mechanism of targeted cation removal and mass transfer process of the CDI were discussed in detail.

Experimental and theoretical study of a new CDI device for the treatment of desulfurization wastewater.

According to the characteristics of desulfurization wastewater, A new capacitive deionization (CDI) device was designed to study the desalination characteristics of desulfurization wastewater in this paper. The experiments investigated the desalination efficiency under different conditions which find that the best desalination efficiency is achieved at a voltage of 1.2V, pH=11 and 50°C. Besides, ion adsorption is more favorable under acidic and alkaline conditions. The anion and cation removal performance experiments showed that the order of cation removal is Mg2+>Na+>Ca2+>K+ and the order of anion removal is Cl->CO32->NO3->SO42->HCO3-. The mechanism of CDI was studied and analyzed by the isothermal adsorption model and COMSOL simulation software. It was found that the Freundlich model and Redlich-Peterson model have a good fit with the experimental results. The experiments show that the CDI device has excellent stability. CDI device was used to treat actual desulfurization wastewater. Furthermore, the study provides theoretical support for the industrial application of CDI for desulfurization wastewater treatment in the future. Graphical abstract.
