However, the practical application of Zn metal anodes is constrained by well-known challenges such as dendrite growth and significant interfacial side reactions. This study introduces a trace amount of taurine (TAU) as a leveling additive into the electrolyte to optimize the microstructure of the electrolyte and the anode interface chemistry. On one hand, the preferential adsorption of TAU on the Zn surface promotes the in situ formation of a stable, protective molecular interfacial layer on the anode, which helps to refine the deposited grains and guide the uniform deposition of Zn2+. On the other hand, the introduction of TAU can regulate the hydrogen bond structure in the electrolyte, reduce the activity of water, thereby significantly inhibiting the occurrence of side reactions such as hydrogen evolution. Consequently, the Zn//Zn symmetric cell system demonstrates an extended cycle life of over 1150 cycles at a current density of 1 mA cm−2 and maintains stable cycling performance for over 600 cycles at 10 mA cm−2. Moreover, the Zn//Cu asymmetric cell system achieves over 1400 cycles of reversible deposition/dissolution at a current density of 1 mA cm−2, with a coulombic efficiency of 99.4%. The incorporation of TAU further enhances the cycle stability of the Zn//MnO2 full cell. These innovative achievements have laid a solid foundation for the broader industrial adoption of aqueous zinc-ion batteries.","PeriodicalId":102,"journal":{"name":"RSC Advances","volume":" 54","pages":" 40247-40254"},"PeriodicalIF":3.9,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/ra/d4ra06825d?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most of the reported MOFs have low electrical conductivity and poor stability, and therefore addressing these problems is crucial for achieving higher electrocatalytic performance. Meanwhile, direct observations of the electrocatalytic behavior, which is of great significance to the understanding of the electrocatalytic mechanism, remain highly challenging. Here, we report on a significant electrocatalytic performance enhancement of Co-MOF-74 for the OER after decoration by copper phthalocyanine (CuPc) molecules. Co-MOF-74@CuPc, synthesized by solvothermal reactions, displays a low overpotential of 293 mV and a robust long-term stability (70 h) at 10 mA cm−2. The enhancement has been attributed to strong electronic interaction between the π-conjugated CuPc molecule and Co-MOF-74, which promotes the electron transfer, increases the electrocatalytic active surface area and regulates the electronic structure during the OER process.","PeriodicalId":102,"journal":{"name":"RSC Advances","volume":" 54","pages":" 40173-40178"},"PeriodicalIF":3.9,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/ra/d4ra05547k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mostly, oral or injectable formulations are used to treat RA, underscoring the critical need for an innovative medication delivery method to enhance therapeutic outcomes and patient compliance. The present study integrated 3D bioprinting and electrospinning technologies to create a unique double-layered transdermal patch (TDDP) for the treatment of RA. The first layer was prepared by 3D-printing a newly developed hydrogel (HG) containing hyaluronic acid (HA) that maintains the joint components and dexamethasone (DEX), an anti-inflammatory agent. A second layer of electrospun polycaprolactone (PCL) nanofibers (NFs) loaded with naringin (NAR), an antimicrobial and anti-inflammatory natural plant extract, was fabricated and integrated with the former layer. The morphology of the NFs was investigated using SEM, and their diameter ranged from 156.28 to 220.66 nm. The physicochemical properties of the suggested TDDP were investigated using FTIR and DSC. The DEX-loaded 3D-printed HG was able to release about 98% of the loaded DEX over a period of 10 days. In vivo experiments definitively confirmed the efficacy of the newly developed TDDPs, showcasing a substantial reduction in the levels of proinflammatory cytokines (IL-6 and TNF-α) through sandwich ELISA measurements in Rattus norvegicus plasma samples. Besides, the stained photomicrographs of the ankle joints of the animals confirmed the alleviation of the RA symptoms via reducing cell infiltration with a preserved joint tissue structure.","PeriodicalId":102,"journal":{"name":"RSC Advances","volume":" 54","pages":" 40187-40197"},"PeriodicalIF":3.9,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/ra/d4ra07306a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While studies have shown the involvement of host metabolic changes (e.g., lipid metabolism and amino acid metabolism) in the development of food allergy (FA), the adaptive changes in glucose metabolism induced by food allergen exposure remain largely unclear. In this study, BALB/c mice were sensitized intraperitoneally with an ovalbumin (OVA)/aluminum adjuvant, followed by oral OVA challenges to induce anaphylaxis. Increased levels of serum OVA-specific IgE and MCPT-1, and Th2 response bias were also presented in FA mice. Subsequently, the intestinal untargeted metabolomic analysis revealed the signature enrichment of glycolysis, manifested by increases in glycolytic metabolites including glucose-6-phosphate, fructose-6-phosphate, 2-phosphoglycerate, and lactate in FA mice. Consistently, the serum lactate level was found to be significantly elevated in allergic mice. Oral administration of OVA also upregulated the expression of critical metabolic enzymes in glycolysis, namely hexokinase 2, phosphoglycerate mutase 1, and lactate dehydrogenase. Moreover, the hypoxia inducible factor-1 (HIF-1) signaling pathway was activated in FA mice, and the expression of HIF-1α, known as the upstream regulator of glycolysis, was increased after oral OVA challenges. In vitro inhibition of HIF-1α was found to impede mast cell inflammatory responses to allergens. In summary, this study demonstrated that OVA-induced FA exhibited a glucose metabolic feature of HIF-1α-mediated glycolysis upregulation, suggesting the potential of HIF-1α/glycolysis targeted strategies in the alleviation of FA.","PeriodicalId":77,"journal":{"name":"Food & Function","volume":" ","pages":""},"PeriodicalIF":5.1,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142875532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a comprehensive evaluation of their impact on modulating albuminuria risk within population-based epidemiological studies is still limited. This study aimed to fill this gap by examining the correlation between flavonoid intake and albuminuria risk, while also shedding light on the potential mediating influence of inflammation in this association. Methods: We utilized data from 29 940 participants spanning three cycles (2007-2008, 2009-2010, and 2017-2018) of the National Health and Nutrition Examination Survey (NHANES). We employed rigorous analytical methods, encompassing logistic regression, restricted cubic splines (RCS), and mediation analysis, to assess the link between dietary flavonoid intake and albuminuria risk. Results: Our findings reveal consistent negative associations between total flavonoids and specific subclasses, including flavonols, flavones, flavan-3-ols, anthocyanidins, and catechins, and the risk of albuminuria. Specifically, after adjusting for confounding factors, each logarithmic unit increase in these flavonoid categories was associated with a decrease in albuminuria risk ranging from 3% to 12%. The mediating proportion of C-reactive protein (CRP) in the relationships between the intake of total flavonoids, flavonols, flavones, catechins, and flavan-3-ols and albuminuria risk was 7.3%, 5.6%, 2.3%, 7.7%, and 4.6%, respectively. Conclusions: These results indicate that increased consumption of flavonoid-rich foods contributes to a reduced risk of albuminuria.","PeriodicalId":77,"journal":{"name":"Food & Function","volume":" ","pages":""},"PeriodicalIF":5.1,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142875533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
