ADT-OH improves intestinal barrier function and remodels the gut microbiota in DSS-induced colitis

Frontiers of Medicine   Pages 972-992 doi: 10.1007/s11684-023-0990-1

Abstract: Owing to the increasing incidence and prevalence of inflammatory bowel disease (IBD) worldwide, effective and safe treatments for IBD are urgently needed. Hydrogen sulfide (H2S) is an endogenous gasotransmitter and plays an important role in inflammation. To date, H2S-releasing agents are viewed as potential anti-inflammatory drugs. The slow-releasing H2S donor 5-(4-hydroxyphenyl)-3H-1,2-dithiole-3-thione (ADT-OH), known as a potent therapeutic with chemopreventive and cytoprotective properties, has received attention recently. Here, we reported its anti-inflammatory effects on dextran sodium sulfate (DSS)-induced acute (7 days) and chronic (30 days) colitis. We found that ADT-OH effectively reduced the DSS-colitis clinical score and reversed the inflammation-induced shortening of colon length. Moreover, ADT-OH reduced intestinal inflammation by suppressing the nuclear factor kappa-B pathway. In vivo and in vitro results showed that ADT-OH decreased intestinal permeability by increasing the expression of zonula occludens-1 and occludin and blocking increases in myosin II regulatory light chain phosphorylation and epithelial myosin light chain kinase protein expression levels. In addition, ADT-OH restored intestinal microbiota dysbiosis characterized by the significantly increased abundance of Muribaculaceae and Alistipes and markedly decreased abundance of Helicobacter, Mucispirillum, Parasutterella, and Desulfovibrio. Transplanting ADT-OH-modulated microbiota can alleviate DSS-induced colitis and negatively regulate the expression of local and systemic proinflammatory cytokines. Collectively, ADT-OH is safe without any short-term (5 days) or long-term (30 days) toxicological adverse effects and can be used as an alternative therapeutic agent for IBD treatment.

Smooth tracking control for conversionmode of a tilt-rotor aircraft with switching modeling Research Article

Kebi LUO, Shuang SHI, Cong PENG

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 11,   Pages 1591-1600 doi: 10.1631/FITEE.2300266

Abstract: This paper investigates the problem in conversion mode of a with a switching modeling method and a technique. Based on the nonlinear model of the conversion mode, a switched linear model is developed by using the Jacobian linearization method and designing the switching signal based on the mast angle. Furthermore, an scheme is designed to deal with the conversion mode control issue. Moreover, instead of limiting the amplitude of control inputs, a method is developed to create bumpless performance. Finally, the XV-15 is chosen as a prototype to illustrate the effectiveness of this developed control method.

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 3, doi: 10.1007/s11783-019-1117-4

Abstract:

The discharge characteristics during the degradation of MNZ by DBD were investigated.

Increasing the discharge frequency can promote the degradation of MNZ.

MNZ removal reaches 99.1% at the initial concentration of 40 ppm within 120 min.

Coexisting organic matter inhibits the degradation of MNZ.

The energy efficiency of DBD for MNZ removal is higher than other technologies.
