State switch control of magnetically suspended flywheel energy storage system in uninterrupted power supply system.

The magnetically suspended flywheel energy storage system (MS-FESS) is an energy storage equipment that accomplishes the bidirectional transfer between electric energy and kinetic energy, and it is widely used as the power conversion unit in the uninterrupted power supply (UPS) system. First, the structure of the FESS-UPS system is introduced, and the working principles at different working states are described. Furthermore, the control strategy of the FESS-UPS is developed, and the switch oscillation of the FESS-UPS system between the charging and discharging states is analyzed.

Prokaryotic and eukaryotic periphyton responses to warming, nutrient enrichment and small omnivorous fish: a shallow lake mesocosms experiment.

Global change stressors, including climate warming, eutrophication, and small-sized omnivorous fish, may exert interactive effects on the food webs and functioning of shallow lakes. Periphyton plays a central role in the primary production and nutrient cycling of shallow lakes but constitutes a complex community composed of eukaryotes and prokaryotes that may exhibit different responses to multiple environmental stressors with implications for the projections of the effects of global change on shallow lakes. We analyzed the effects of warming, nutrient enrichment, small omnivorous fish and their interactions on eukaryotic and prokaryotic periphyton structures in shallow lake mesocosms.

Mannose-modified exosomes loaded with MiR-23b-3p target alveolar macrophages to alleviate acute lung injury in Sepsis.

The anti-inflammatory role of miR-23b-3p (miR-23b) is known in autoimmune diseases like multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. However, its role in sepsis-related acute lung injury (ALI) and its effect on macrophages in ALI remain unexplored. This investigation aimed to evaluate miR-23b's therapeutic potential in macrophages in the context of ALI.

Clinical significance analysis of microRNA-199a-3p in gingival crevicular fluid for patients with chronic periodontitis.

Objective: The aim was to investigate the clinical performance of microRNA-199a-3p (miR-199a-3p) in patients with chronic periodontitis.

Methods: 91 patients with chronic periodontitis and 78 healthy individuals were enrolled for the research subjects. MiR-199a-3p expression was detected using real-time quantitative PCR (RT-qPCR) assay.

GALNT5 promotes migration and invasion of pancreatic ductal adenocarcinoma cells by activating Erk signaling pathway.

Aberrant glycosylation has been implicated in promoting the progression and metastasis of pancreatic ductal adenocarcinoma (PDAC). However, the contribution of different glycosylation-related genes in PDAC remains to be clarified. In this study, we performed a differential analysis of RNA-Seq data from TCGA and GTEx and found GALNT5 as the most significant upregulated glycosylation-related gene in PDAC.
