Peptidoglycan recognition proteins (PGRPs) are members of an important class of pattern recognition receptors in insects that can specifically recognize peptidoglycan (PGN) in bacterial cell walls and participate in immune regulation and bacterial clearance. Although the role of PGRPs in regulating the innate immune response in Drosophila melanogaster has been studied, little is known regarding PGRPs in Lepidoptera species. In this study, five short (S)-type Bombyx mori PGRPs (BmPGRPs) were cloned, expressed, and evaluated for their function in innate immunity.

Article Synopsis
  • The study involved preparing Al2O3 as a support for catalysts using the sol-gel method and creating manganese oxide (MnOx) and cerium oxide (CeO2) catalysts through isometric impregnation.
  • The experiments focused on the SCR denitrification process using NH3 and examined catalysts' physicochemical properties via BET, XRD, and SEM to analyze their performance.
  • Results indicated that the optimal MnOx/Al2O3 catalyst was achieved with a 7% MnOx loading and a 4% CeO2 addition, with a calcination temperature of 550 degrees C enhancing catalytic activity and stability.

The influence of some experimental factors on removal efficiency of nitric oxide (NO) under the condition of liquid-phase oxidation with UV/H2O2, such as H2O2 concentration, solution temperature, initial pH, NO concentration, illumination condition, O2 content and gas flow rate, were investigated by employing orthogonal experiments and single factor experiments. The results showed that NO could be efficiently removed by the aqueous oxidation technology with UV/H2O2 system, and the highest NO removal rate was about 80%. Moreover, H2O2 concentration, temperature and initial pH had varying degree effects on purifying NO-containing gas, whereas NO removal rate were more affected by H2O2 concentration and temperature.

A cake collapse model was developed by taking the combined effects of fractal dimension, relaxation ratio, coordination number, and aggregate diameter into consideration. The cake porosity including intraaggregate and interaggregate porosities was modeled successively by three typical coordination numbers (n = 6, 8, and 12). Accordingly, an inversion method made it possible to deduce the coordination number using the measured cake porosities, and the reverse-calculated value with minimum error and the corresponding relaxation ratios were applied as the parameters for the model.

The catalysts were prepared by activated carbon fiber (ACF) loaded different contents of NiO and NiO-CeO2, Urea was loaded on the prepared catalysts as reductant. The experiments of selective catalytic reductions (SCR) of NO were carried out from 30 to 120 degrees C. The experiments of SEM, BET and XRD of the samples were also carried out selectively to study the catalysts properties, respectively.

Surfactants increase wetting, solubilization of carbon black and reduce interfacial tension between surfactants and carbon black are very important for the wet removal of furnace smoke. Calculated hydrophile-lipophile balance value (HLB), critical micelle concentration (CMC) and Gibbs-free-energy (deltaG0(mf)) of mixed surfactants solution generated on the basis of selected mathematical models. The CMC of AEO-9, SDBS solution at different ratios and smoke removal efficiency at the CMC were gained by experiments.

The active carbon fiber (ACF) loaded different contents of La2O3 catalysts were prepared, and their catalytic activities and durability for the purification of NO were investigated, and for comparison, those of ACF and HNO3/ACF for the title reaction were also investigated. The orthogonal experiment results showed that the best volume fraction of oxygen in the mixed gas was 5%, and the best air speed of mixed gas was 5000 m3 (m3 x h)(-1). The catalytic experiment results showed that the activity of HNO3/ACF was better than that of ACF when the temperature was below 414.
