However, the protective role of <em>Ginkgo biloba</em> seed polysaccharide against NAFLD remains unclear. In this study, we isolated and purified polysaccharide (GBSP-2) from <em>Ginkgo biloba</em> seeds.

By studying a mouse model, we investigated the effect of GBSP-2 (100 or 200 mg/kg) on high-fat-diet-induced NAFLD. We demonstrated that GBSP-2 significantly alleviated NAFLD, as evidenced by reduced hepatic steatosis, decreased inflammation, improved oxidative stress and ameliorative glucolipid metabolic disorders. Furthermore, GBSP-2 mitigated gut microbiota disturbance of NAFLD mice and markedly increased the abundance of <em>Akkermansia</em>, <em>Romboutsia</em>, <em>Lactobacillus</em> and <em>Bacteroides</em>. Mechanistically, GBSP-2 could activate AMPK/ACC signaling pathway to inhibit lipid synthesis by generating 3,4-dihydroxyphenylpropionic acid (DHPPA).

Doxycycline is an antibiotic that requires an effective immune function but paradoxically has immune-attenuating effects by reducing TLR2 activity, potentially increasing antibiotic needs. We hypothesize that IMMPs are recognized by various cell surface TLRs, leading to the activation of the NF-κB signaling pathway. Furthermore, IMMPs' immune-stimulating effect could prevent the doxycycline-induced reduction of TLR2 activity in immune cells.

Additionally, preincubation of macrophages with IMMPs enhanced cytokine production and partially prevented doxycycline-induced cytokine reduction in response to TLR2 activation. Molecular docking analyses support IMMPs and doxycycline binding to these TLRs.

Phase changing materials (PCM) are promising thermal storage and management materials which have potential to mitigate food waste, yet they often suffer from leakage and non-shape stability. Here, a green shape-stabilized polyethylene glycol 300 (PEG) nanocellulose-based composite was developed using readily available and cost-effective side streams from the brewery industry. Two different routes were examined for the incorporation of PEG into the cellulose nanofiber (CNF) cryogel including adding different dry mass ratios of PEG in the sol stage, with or without physical crosslinking, or adding the PEG after CNF gelation. FTIR and TGA analysis revealed the improved thermal stability of PEG after incorporation into the CNF cryogel. The PEG/CNF composite produced by adding PEG in the gel stage outperformed the other material formulations by demonstrating the highest enthalpy value (93.2 J/g) and the best mechanical properties (Young's modulus of 140 kPa). The package containing the PEG/CNF composite could maintain the meat temperature below 0 °C around 4 times longer than the control package when the cold system was interrupted. Furthermore, the PEG/CNF composite showed a positive effect on the color and drip loss values of frozen meat.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"349 ","pages":"Article 123031"},"PeriodicalIF":10.7,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142705167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
