Objective This study aimed to investigate the lipid-lowering activity of LFBEP-C1 in high glucose-fed Caenorhabditis elegans(C.elegans).Methods In this study,the fermented barley protein LFBEP-C1 was prepared and tested for its potential anti-obesity effects on C.elegans.The worms were fed Escherichia coli OP50(E.coli OP50),glucose,and different concentrations of LFBEP-C1.Body size,lifespan,movement,triglyceride content,and gene expression were analyzed.The results were analyzed using ANOVA and Tukey's multiple comparison test.Results Compared with the model group,the head-swing frequency of C.elegans in the group of LFBEP-C1 at 20μg/mL increased by 33.88%,and the body-bending frequency increased by 27.09%.This indicated that LFBEP-C1 improved the locomotive ability of C.elegans.The average lifespan of C.elegans reached 13.55 days,and the body length and width of the C.elegans decreased after LFBEP-C1 intake.Additionally,LFBEP-C1 reduced the content of lipid accumulation and triglyceride levels.The expression levels of sbp-1,daf-2,and mdt-15 significantly decreased,while those of daf-16,tph-1,mod-1,and ser-4 significantly increased after LFBEP-C1 intake.Changes in these genes explain the signaling pathways that regulate lipid metabolism.Conclusion LFBEP-C1 significantly reduced lipid deposition in C.elegans fed a high-glucose diet and alleviated the adverse effects of a high-glucose diet on the development,lifespan,and exercise behavior of C.elegans.In addition,LFBEP-C1 regulated lipid metabolism mainly by mediating the expression of genes in the sterol regulatory element-binding protein,insulin,and 5-hydroxytryptamine signaling pathways.

Engineering transition metal compounds(TMCs)catalysts with excellent adsorption-catalytic ability has been one of the most effec-tive strategies to accelerate the redox kinetics of sulfur cathodes.Herein,this review focuses on engineering TMCs catalysts by cation doping/anion doping/dual doping,bimetallic/bi-anionic TMCs,and TMCs-based heterostructure composites.It is obvious that introducing cations/anions to TMCs or constructing heterostructure can boost adsorption-catalytic capacity by regulating the electronic structure including energy band,d/p-band center,electron filling,and valence state.Moreover,the elec-tronic structure of doped/dual-ionic TMCs are adjusted by inducing ions with different electronegativity,electron filling,and ion radius,resulting in electron redistribution,bonds reconstruction,induced vacancies due to the electronic interaction and changed crystal structure such as lat-tice spacing and lattice distortion.Different from the aforementioned two strategies,heterostructures are constructed by two types of TMCs with different Fermi energy levels,which causes built-in electric field and electrons transfer through the interface,and induces electron redistribution and arranged local atoms to regulate the electronic structure.Additionally,the lacking studies of the three strategies to comprehensively regulate electronic structure for improving catalytic performance are pointed out.It is believed that this review can guide the design of advanced TMCs catalysts for boosting redox of lithium sulfur batteries.

Lithium sulfur(Li-S)battery is a kind of burgeoning energy storage system with high energy density.However,the electrolyte-soluble intermediate lithium polysulfides(Li PSs)undergo notorious shuttle effect,which seriously hinders the commercialization of Li-S batteries.Herein,a unique VSe_(2)/V_(2)C heterostructure with local built-in electric field was rationally engineered from V_(2)C parent via a facile thermal selenization process.It exquisitely synergizes the strong affinity of V_(2)C with the effective electrocatalytic activity of VSe_(2).More importantly,the local built-in electric field at the heterointerface can sufficiently promote the electron/ion transport ability and eventually boost the conversion kinetics of sulfur species.The Li-S battery equipped with VSe_(2)/V_(2)C-CNTs-PP separator achieved an outstanding initial specific capacity of 1439.1 m A h g^(-1)with a high capacity retention of 73%after 100 cycles at0.1 C.More impressively,a wonderful capacity of 571.6 mA h g^(-1)was effectively maintained after 600cycles at 2 C with a capacity decay rate of 0.07%.Even under a sulfur loading of 4.8 mg cm^(-2),areal capacity still can be up to 5.6 m A h cm^(-2).In-situ Raman tests explicitly illustrate the effectiveness of VSe_(2)/V_(2)C-CNTs modifier in restricting Li PSs shuttle.Combined with density functional theory calculations,the underlying mechanism of VSe_(2)/V_(2)C heterostructure for remedying Li PSs shuttling and conversion kinetics was deciphered.The strategy of constructing VSe_(2)/V_(2)C heterocatalyst in this work proposes a universal protocol to design metal selenide-based separator modifier for Li-S battery.Besides,it opens an efficient avenue for the separator engineering of Li-S batteries.

OBJECTIVE: To explore the mechanism by which Tongqiao Yizhi granule（通窍益智颗粒, TQYZKL） intervenes pyroptosis to treat vascular dementia（VaD） in a rat model. METHODS: The rat model of VaD was established by two-vessel occlusion（2VO）. The rats were randomly divided into Sham group, Model group, Nimodipine group, TQYZKL（6.2 g·kg-1·d-1）, TQYZKL(12.4 g·kg-1·d-1), TQYZKL(24.8 g·kg-1·d-1). The Morris water maze（MWM） test was carried out to test the learning and memory function; Hematoxylin-eosin staining and transmission electron microscopy（TEM） to observe the pathological damage in the hippocampus; Tunel fluorescence staining to detect neuronal pyroptosis in the hippocampus. The expression levels of pyroptosis-related proteins, namely Golgi peripheral membrane protein p65（P65）, nucleotide oligomerization domain-like receptors 3（NLRP3）, caspase-1 and Gasdermin D（GSDMD）, were detected using Western blotting and reverse transcription polymerase chain reaction. Moreover, the serum levels of interleukin-1β（IL-1β） and interleukin-18（IL-18） were determined through the enzyme-linked immunosorbent assay. RESULTS: The study revealed that TQYZKL effectively improved the ability of VaD ratsto learn and memorize, relieved the pathological damage in the hippocampus, restored neuronal morphology, and reduced the expression of pyroptosis-related proteins P65, NLRP3, caspase-1, GSDMD-N, IL-18 and IL-1β（P < 0.05）. CONCLUSION: TQYZKL inhibits neuronal pyroptosis in the hippocampus of VaD rats by regulating nuclear factor kappa-B/NLRP3/caspase-1 signaling pathway, thus exerting a therapeutic effect on VaD in the rats.

未来食品学报(英文) 2024年第3期4卷 258-266页

作者： juan bai Linzhao He Jinfu Zhang Xiangyue Gu Beiqi Wu Anlin Wang Ying Zhu Jiayan Zhang Yansheng Zhao Jie Yuan Xiang Xiao School of Food and Biological Engineering Jiangsu UniversityZhenjiang 212013China

Highland barley is a well-known cereal in Qinghai-Tibet Plateau area with high nutritional value,which has been reported to be a health-promoting grain for the obesity and the diabetes.Fermentation by certain microbiota can improve the flavor property and nutritional characteristics.In the present study,Lactiplantibacillus plantarum and Saccharomyces cerevisiae were singly or jointly applied to ferment highland barley,and the profile of volatile substances and lipid-lowering effects of the respective extracts were analyzed.Results indicated that either L.plantarum or S.cerevisiae or co-fermentation could consume the polysaccharides of highland barley to provide energy,and dramatically increase the contents of total protein and polyphenol.Gas chromatography-mass spectrometry(GC-MS)analysis revealed that the presence of S.cerevisiae was critical for production of the pleasant flavors,especially for the ethyl ester substances including hexadecanoic acid ethyl,hexanoic acid ethyl ester and so on.Meanwhile,we found that fermented highland barley extracts by L.plantarum exhibited stronger lipid-lowering effects in Caenorhabditis elegans than that by S.cerevisiae,while the co-fermentation not only emitted pleasant odors but also exerted high hypolipidemic function.In all,co-fermentation by L.plantarum and S.cerevisiae was proposed to be a promising processing to improve the flavor and functional properties of highland barley.

Bitter Melon Powder Protects against Obesity-associated Fatty Liver Disease by Improving Colonic Microenvironment in Rats with High-fat Diet-induced Obesity

引用

Biomedical and Environmental Sciences 2017年第8期30卷 611-615页

作者： bai juan ZHU Ying DONG Ying School of Food and Biological Engineering Jiangsu University Zhenjiang 212013 Jiangsu China

This study explored how bitter melon powder （BMP） alters the colonic microenvironment during the development of obesity-associated fatty liver in rats. We observed that BMP effectively inhibited the body weight gain and lipid accumulation in the liver, ameliorated glucose intolerance, and increased the colon weight after an 8-week treatment compared to that in the high-fat diet （HFD） group. BMP significantly decreased fecal water toxicity towards HT-29 cells, as revealed by the cell counting kit （CCK）-8 assay results, and the mRNA expression of Toll-like receptor 4 （TLR4） in colon mucosa. Additionally, gut permeability in the BMP group was restored to normal levels. Finally, BMP alleviated the inflammatory state of the rat colon mucosa and liver tissues as well as the systemic inflammation.

Biomedical and Environmental Sciences 2019年第8期32卷 578-591页

作者： XIAO Xiang bai juan LI Ming Song ZHANG Jia Yan SUN Xin juan DONG Ying School of Food and Biological Engineering Jiangsu University

Objective We aimed to explore how fermented barley extracts with Lactobacillus plantarum dy-1(LFBE) affected the browning in adipocytes and obese rats.Methods In vitro, 3T3-L1 cells were induced by LFBE, raw barley extraction(RBE) and polyphenol compounds(PC) from LFBE to evaluate the adipocyte differentiation.In vivo, obese SD rats induced by high fat diet(HFD) were randomly divided into three groups treated with oral gavage:(a) normal control diet with distilled water,(b) HFD with distilled water,(c) HFD with 800 mg LFBE/kg body weight(bw).Results In vitro, LFBE and the PC in the extraction significantly inhibited adipogenesis and potentiated browning of 3T3-L1 preadipocytes, rather than RBE.In vivo, we observed remarkable decreases in the body weight, serum lipid levels, white adipose tissue(WAT) weights and cell sizes of brown adipose tissues(BAT) in the LFBE group after 10 weeks.LFBE group could gain more mass of interscapular BAT(IBAT) and promote the dehydrogenase activity in the mitochondria.And LFBE may potentiate process of the IBAT thermogenesis and epididymis adipose tissue(EAT) browning via activating the uncoupling protein 1(UCP1)-dependent mechanism to suppress the obesity.Conclusion These results demonstrated that LFBE decreased obesity partly by increasing the BAT mass and the energy expenditure by activating BAT thermogenesis and WAT browning in a UCP1-dependent mechanism.
