Summary: The combination of lactic acid, nisin, and ultrasound showed a strong synergistic effect in reducing Listeria monocytogenes and Escherichia coli O157:H7 in enoki mushrooms. The transmission electron microscopy analysis demonstrated collapse of peripheral cytoplasm layers and breakage of cell wall structures in L. monocytogenes exposed to the combined treatments. These findings suggest the potential of using this combination for controlling the mushroom carriage of harmful bacteria.

Summary: This study compared different methods to reduce and prevent cross-contamination of Listeria monocytogenes and L. innocua on Fuji apples. The results showed that using a dip procedure with 0.25 ml/dL H2O2-PAA was the most effective in reducing the contamination for both L. monocytogenes and L. innocua. Additionally, using a low pressure, conventional, hand-held garden sprayer with 0.25 ml/dL H2O2-PAA minimized the cross-contamination rate. The study also found that L. innocua is a suitable surrogate for L. monocytogenes on apples.

Summary: A novel proteoglycan named PGD1-1 was isolated from Flammulina velutipes, with anti-proliferation and pro-apoptotic activities demonstrated against HepG-2 cells. PGD1-1 significantly inhibited cell proliferation by affecting lipid peroxidation and nitric oxide production, and promoted early apoptosis in HepG-2 cells. This suggests that PGD1-1 may serve as a potent ingredient for inhibiting the proliferation of HepG-2 cells and provide a basis for the development of functional ingredients from F. velutipes.

Summary: The study revealed a low contamination incidence of L. monocytogenes in cattle and sheep farm environments but a high incidence in slaughtering environments. L. innocua was more common and significantly higher than L. monocytogenes in both farm and slaughtering environments. Molecular and genetic analyses indicated the transmission of Listeria from farm and slaughtering environments to end products, with certain strains associated with human listeriosis cases in China. Virulence markers and antibiotics resistance of L. monocytogenes suggest a potential public health risk.

Summary: The Markov Chain Monte Carlo (MCMC) method is increasingly popular in uncertainty analysis of hydrological simulation. However, the estimation of the constant standard deviation (02) in the approach is subjective, hindering performance improvement. This study investigates the statistical meaning of parameter 02 and develops a new label called Confidence Level of Model (CLM) to interpret it. The MCMC method based on CLM performs well in generating regular posterior distributions and narrow, symmetrical confidence intervals.

Summary: This study investigates the influence of board culture on bank innovation and explores the mechanisms involved. Using the cultural context of the East and state-owned bank attributes, data from China's A-share listed banks between 2003 and 2018 were analyzed. Results indicate that indicators of masculinity, indulgence, and cultural diversity are positively correlated with bank innovation, while power distance and uncertainty avoidance are negatively correlated. Further analysis reveals that the impact of Oriental culture on bank innovation is mediated by human capital investment, efficiency, and risk-taking. The findings remain robust after controlling for endogenous issues and factors such as Confucian culture.
