4. Volatile contributions to aviation nvPM: a mass spectrometric analysis of nvPM emissions

Author

Yu, Z. and Miake-Lye, R.C.

Abstract

Certification standards for non-volatile particulate matter (nvPM) emissions from aircraft engines have recently been adopted by ICAO as the CAEP10 standard in 2016 and the CAEP11 standard in 2019. The measurements of the nvPM levels are prescribed in ICAO (2019) and SAE documents (2021). The measurement system specifications are designed to minimize the volatile contributions to the measured nvPM quantities. In a series of “certification-like” measurement campaigns that were used to collect data for developing the ICAO nvPM standards, the volatile particulate matter (vPM) contributions to the measured nvPM were quantified. An Aerosol Mass Spectrometer (AMS) in concert with a Cavity Attenuation Phase Shift (CAPS) monitor were used to measure the vPM and nvPM levels, respectively. These vPM contributions are primarily representative of coatings on the nvPM soot particles. Data from a range of engine designs were collected and the relative amounts of vPM to nvPM were ascertained to determine how much the vPM component could affect the nvPM quantification. For the engines evaluated, which span a variety of in‑service engines in the commercial fleet, the vPM contributions are small, averaging 3 % of the nvPM mass value, and were usually relatively independent of engine power condition.

9. Synthesis of Multicomponent Carbides by the Vacuum-Free Electric-Arc Method

Author

Gumovskaya, A. A., Vasilyeva, Yu. Z., Pak, A. Ya., and Mamontov, G. I.

Abstract

This paper presents the results of experimental studies in the field of the electric-arc synthesis of a solid solution of TiZrNbHfTaC5multicomponent carbide using an atmospheric plasma reactor. The implementation of the synthesis of carbide in air is possible due to the formation of a buffer layer of carbon monoxide, which prevents the oxidation of synthesis products. It is shown that when TiO2, ZrO2, Nb2O5, HfO2, and Ta2O5metal-oxide powders are used as precursors, it is possible to provide such parameters of the synthesis process that ensure the formation of a high-entropy TiZrNbHfTaC5carbide phase with a face-centered cubic lattice. According to the data of transmission electron microscopy, the synthesis products contain particles with a wide size distribution from tens of micrometers to submicron and nanoscale ones.

31. MicroRNA-137 inhibits pituitary prolactinoma proliferation by targeting AKT2

Author

Xu, Q., Yu, Z. X., Xie, Y. L., Bai, L., Liang, S. R., Ji, Q. H., and Zhou, J.

Abstract

Purpose: Prolactinoma is the most common type of pituitary adenoma. Most prolactinoma need medical treatment, but some of them are aggressive and require surgery. In previous decades, some miRNAs have been manifested as oncogenes or tumor suppressors. Consequently, miRNAs' abnormal expression involves tumorigenesis, invasion, and metastasis of different types of tumors, including pituitary tumors. The current study aim to explore the aggressiveness-associated miRNAs in prolactinoma and underlying molecular mechanisms based on the bioinformatic analysis and fundamental experiment studies. Methods: GSE46294 miRNA expression profile from the Gene Expression Omnibus (GEO) database was downloaded. Differentially expressed miRNAs (DEMs) were filtered from this data. Subsequently, the target genes of downregulated miRNAs were analyzed by Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment. RT-qPCR, western blot, and CCK-8 assays were used to validate the effect of miR-137 on the proliferation of MMQ cells through AKT2. Finally, the binding site of rat miR-137 to AKT2 were predicted by Targetscanand Bibiservdatabase, and verified by double luciferase reporter assay. Results: Twenty-four changed DEMs (fourteen upregulated and ten downregulated) were identified. Target genes of downregulated DEMs were classified into three groups by GO terms. KEGG pathway enrichment analysis revealed these target genes enriched in the PI3K-Akt pathway. We also confirmed that miR-137 can target AKT2 and inhibit the proliferation of MMQ cells induced by AKT2. Conclusion: MiR-137 suppressed prolactinomas' aggressive behavior by targeting AKT2.
