A Scalable and Robust Water Management Strategy for PEMFCs: Operando Electrothermal Mapping and Neutron Imaging Study.

Effective water management is crucial for the optimal operation of low-temperature polymer electrolyte membrane fuel cells (PEMFCs). Excessive liquid water production can cause flooding in the gas diffusion electrodes and flow channels, limiting mass transfer and reducing PEMFC performance. To tackle this issue, a nature-inspired chemical engineering (NICE) approach has been adopted that takes cues from the integument structure of desert-dwelling lizards for passive water transport.

Effects of Spermidine on Mouse Gut Morphology, Metabolites, and Microbial Diversity.

Spermidine is a class of biologically active organic small molecules that play an important role in maintaining intestinal homeostasis. The specific objective of this study was to explore the effects of spermidine on intestinal morphology, metabolites, and microbial diversity in mice. We showed that 0.

[Phytoestrogen-like effect of Siwu Decoction and molecular mechanism: based on network pharmacology and in vivo experiment].

This study explored the phytoestrogen-like effect of Siwu Decoction(SWD) and the estrogen receptor(ER)-mediated molecular mechanism based on network pharmacology and in vivo experiment. The active components and targets of SWD were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and related targets of "estrogen" from GeneCards and Online Mendelian Inheritance in Man(OMIM). Cytoscape and STRING were employed to construct the protein-protein interaction(PPI) network and "chemical component-target-disease" network and core targets were identified, followed by Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment of the core targets by R software.
