Metabolomic profiles in allergic rhinitis: A systematic review and meta-analysis.

Background: Allergic rhinitis (AR) is a prevalent chronic inflammatory condition that significantly affects patient quality of life and poses a substantial public health burden. Recent advancements in metabolomics have facilitated a deeper understanding of the metabolic pathways involved in AR, offering potential for new biomarkers and therapeutic targets.

Objective: To conduct a systematic review and meta-analysis of clinical studies summarizing the metabolomic profiles of AR to gain deeper insights into the metabolic changes and pathologic processes underlying AR.

Biomolding Technique to Fabricate the Hierarchical Topographical Scaffold of POMA To Enhance the Differentiation of Neural Stem Cells.

In this paper, a biomolding technique was first used to fabricate a scaffold of hierarchical topography with biomimetic morphology for tissue engineering. First, poly(-methoxyaniline) (POMA) was synthesized by conventional oxidative polymerization, followed by characterizations with Fourier transform infrared spectroscopy (FTIR) and gel permeation chromatography (GPC). Moreover, the POMA scaffold with 3D biomimetic morphology was fabricated using poly(dimethylsiloxane) (PDMS) as negative soft template from natural leaf surfaces of , followed by transferring the pattern of PDMS template to POMA.
