Emulsion gels, also known as gelled emulsions or emulgels, have garnered great attention both in fundamental research and practical applications due to their superior stability, tunable morphology and microstructure, and...

BackgroundHashimoto’s thyroiditis, an autoimmune thyroid disease, shows high morbidity worldwide, particularly in female. Patients with Hashimoto’s thyroiditis have an increasing risk of hypothyroidism during the occurrence and progression of Hashimoto’s thyroiditis. In recent years, metabolomics has been widely applied in autoimmune diseases, especially thyroid disorders. However, metabolites analysis in Hashimoto’s thyroiditis is still absent.MethodsA total of 92 samples were collected, including 35 cases in the control group, 30 cases in the Hashimoto’s thyroiditis with euthyroidism group, and 27 cases in the Hashimoto’s thyroiditis with subclinical hypothyroidism group. SPSS 25.0 for statistical analysis and ROC curve, SIMCA 14.0, Metaboanalysis for multifactor analysis, and Origin 2021 for correlation analysis.Results21 metabolites were identified. 10 metabolites were obtained from control group versus HTE group, 8 serum metabolites were abnormal between control group and HTS group, 3 metabolites were derived from HTE group versus HTS. Kyoto Encyclopedia of Genes and Genomes Enrichment analysis showed that fatty acid degradation, Arginine, and proline metabolism have a significant impact on HTE, while lysine degradation, tyrosine metabolism play an important role HTS group, compared to control group. In the comparison between the HTE and HTS group, Valine, leucine, and isoleucine degradation and Valine, leucine, and isoleucine biosynthesis exists a key role. Correlation analysis shows clinical are not related to metabolites. ROC curve indicates SM, LPC, PC can efficiency in identification patients with HT in different clinical stage from healthy individuals.ConclusionSerum metabolites were changed in HT. Phospholipids such as SM, LPC, PC influence the pathogenesis of Hashimoto’s thyroiditis. Fatty acid degradation and lysine degradation pathways have an impact on different clinical stage of HT.

Janus particles, having the property integration of each component, have attracted increasing attention due to their considerable potential in the field of material engineering applications. However, organic solvents or sophisticated equipment during the fabrication processes is generally inevitable. Here, we report a facile route to prepare Janus droplets and hydrogels via aqueous two-phase systems (ATPS). Simply merging two polymers, i.e., polyethylene glycol (PEG) and dextran (DEX), aqueous droplets on a superamphiphobic surface leads to phase separation, provided that their concentrations exceed the threshold in the mixed aqueous droplets, thus generating a Janus structure. Various morphologies of such Janus droplets can be well controlled by manipulating the locations of these two polymers' concentration on the phase diagram, and the evolution of the mixed droplets are deterministic on the basis of the kinetics of their phase separation and the degree of hydrophobicity of the substrate. Introducing monomers and/or nanoparticles, further, into a certain phase of the ATPS droplet followed by photopolymerizing enables Janus hydrogel particles with diverse functionalities to be obtained. The ease and green techniques with which the Janus balance and curvature between two phases of the Janus droplet can be finely tuned point to new directions in designing Janus particles and hold great promises in biological engineering.

Background TgAb and TPOAb are effective and sensitive diagnose index for HT which is a common AID.TgAb and TPOAb present varying degrees correlatuion with different metabolites in different gender. However, the morbidity in female are higher than male in HT. The research in exploring the correction between metabolic and positive-TgAb or positive-TPOAb in female HT patients is still absent. Methods 14 healthy, 14 TPOAb(+), 4 TgAb(+) patients serum sample were included. Metabolites were detected using the LC-MS. Sstatistical analysis were performed by SPSS. PLS-DA and OPLS-DA were carried by SIMCA. VIP > 1.5 metabolites by OPLS-DA were assessed for statistical significance by t-test or non-parametric test. Enrichment analysis and heatmap of metabolite were conducted by MetaboAnalyst. Correlation analysis was performed by Origin 2021. The ROC curve was established by SPSS. Metabolite point plotting was drawn by Graph prism 9.0. Results Based on VIP > 1.5 and P < 0.05 as selection criteria, 36 metabolites were derived. 13 metabolites were selected from the control vs the TPOAb (+) group, 23 metabolites were identified from the control vs the TgAb (+) group. TgAb and Phenylacetyl-L-glutamine / TPOAb and LPC 16:0 sn-1 performed strong correlation the TPOAb (+) group. Furthermore, TPOAb and LPE 16:1 was presented correlation the TgAb (+) group. Enrichment analysis of metabolic pathways showed that Glycine, serine and threonine metabolism was significant in TPOAb (+), while Galactose metabolism in TgAb (+) group. Conclusion The level of serum metabolites in TPOAb(+) TgAb(-) female patients and TPOAb(-) TgAb(+) female patients are different.
