Mucin 2 (MUC2) is a critical component of the intestinal mucus barrier. Lactic acid bacteria (LAB) strains can improve mucosal homeostasis. In this study， we determined the expression of Muc2 induced by dead bacteria and cell-free conditioned medium (CM) of 50 LAB strains in the human goblet cell line， LS174T. Dead bacteria or CM of LAB affected the Muc2 expression in a species- and strain-specific manner under homeostasis. Next， LAB strains with different regulatory abilities were selected， gavaged into mice， and exposed to dextran sodium sulfate (DSS) after 1 week. Different LAB strains inhibited intestinal injury to different degrees， with Lactobacillus acidophilus FCQHC4L1 exerting the most potent effect. FCQHC4L1 significantly decreased the secretion of pro-inflammatory factors， promoted the expression and secretion of mucin， and inhibited colitis development. This strain also regulated the gut microbiota and increased the secretion of butyric acid. Moreover， CM of FCQHC4L1 inhibited endoplasmic reticulum (ER) stress and ameliorated the abnormal expression of MUC2 by suppressing the activation of the GRP78/ATF6 and GRP78/IRE1/XBP1 signaling pathways. Our results highlight the potential of FCQHC4L1 as a therapeutic agent for strengthening the mucus barrier and improving the gut health.

Optical networks are evolving toward ultrawide bandwidth and autonomous operation. In this scenario, it is crucial to accurately model and control optical power evolutions(OPEs) through optical amplifiers(OAs), as they directly affect the signal-to-noise ratio and fiber nonlinearities. However, a fundamental contradiction arises between the complex physical phenomena in optical transmission and the required precision in network control. Traditional theoretical methods underperform due to ideal assumptions, while data-driven approaches entail exorbitant costs associated with acquiring massive amounts of data to achieve the desired level of accuracy. In this work, we propose a Bayesian inference framework(BIF) to construct the digital twin of OAs and control OPE in a data-efficient manner. Only the informative data are collected to balance the exploration and exploitation of the data space, thus enabling efficient autonomous-driving optical networks(ADONs). Simulations and experiments demonstrate that the BIF can reduce the data size for modeling erbium-doped fiber amplifiers by 80% and Raman amplifiers by 60%. Within 30 iterations, the optimal controlling performance can be achieved to realize target signal/gain profiles in links with different types of OAs. The results show that the BIF paves the way to accurately model and control OPE for future ADONs.

0 INTRODUCTION To relieve the short supply of suitable land for residing,cultivating,and commerce,it is accepted to reclaim land from lakes,river estuaries,and coastal regions in many countries(Mancini et al.,2020).The large-scale reclamation activities have an irreversible effect on the mico-geomorphology and hydrodynamic system of seasonally flooded areas(Zhang et al.,2019;Yu et al.,2018).For example,coastal regions reclaimed extended the groundwater flow paths,as well as created groundwater level rise,resulting in water-logging in the reclaimed area(Hu et al.,2008).Similar changes in groundwater flow systems may alter groundwater-lake water interactions,and it can ultimately affect the water cycle in the lake ***,such detailed studies are presently *** addition,natural exchanges between the lake and groundwater systems can be strongly affected by physical hydrological processes(Javadzadeh et al.,2020),chemical properties(Kamtchueng et al.,2015),and bioto behavior(Hancock et al.,2005).
