Journal of Materials Science & Technology 2021年第10期69卷 119-128页

In this study, we reported the in-situ fabrication of a series of Fe_(2)O_(3)/TiO_(2) monolithic catalysts on flexible Ti mesh via plasma electrolytic oxidation process, hydrothermal reaction and chemical bath deposition(CBD) method. The morphology tailoring of Fe_(2)O_(3) nanostructures finds that Fe2O3 nanosheets supported on TiO2 exhibit superior catalytic performance with a complete oxidation of CO at 260℃. The catalytic stability test indicates that the in-situ grown Fe_(2)O_(3)/TiO_(2) catalysts own outstanding performance for continuous CO oxidation due to the strong substrate adhesion without mass loss. The microstructures and interfaces of Fe_(2)O_(3)/TiO_(2) catalysts are well studied using series of characterization techniques. The in-situ preparation strategy of metal oxide catalysts in this work will open up more opportunities for the rational design of variety of monolithic catalysts used for CO oxidation, de-NO_(x), three-way catalysis and other related application in industry.

Stability study of Disperse Blue 79 under ionizing radiation

Ionizing radiation is a promising method for dye degradation or textile coloration using commercial azo dyes and small molecular weight organic dyes. Thus, the stability of the molecular structure of an azo dye is important under ionizing radiation. Disperse Blue 79, as an example azo dyes, was irradiated with gamma rays or electron beam (EB) to investigate the radiation-induced effects on the molecular structure. Ultraviolet visible spectroscopy (UV Vis), nuclear magnetic resonance (NMR) spectra analysis, and mass spectrometry (MS) studies indicated that acetoxy and methoxyl were easily cleaved on the irradiation of the aqueous dye solution but retained a stable structure on the irradiation of the powder form. Gamma rays and EB showed similar effects on the decomposition process. Chromaticity changes using the Lab* method showed that the dye turned to dark yellow and the value of b* of the irradiated dyes increased with the increasing absorbed dose, which indicated that Disperse Blue 79 could be partly decomposed in an aqueous solution This work was nancially supported by the National Natural Science Foundation of China (Nos. 11875313, 11605274, and 11575277).

Furthermore, the results demonstrated that the chemical stability of the Disperse Blue 79 under ionizing radiation are different in its powder form with the dye in the aqueous solution.

The Hippo pathway and its correlation with acute kidney injury

Zoological Research 2022年第5期43卷 897-910页

作者： Chi zhang Chuan-Lei li Ke-xin Xu Zhi-Huang zheng Guo-Zhe Cheng Hui-Juan Wu Jun liu Department of Nephrology Shanghai General HospitalShanghai Jiaotong University School of MedicineShanghai 201600China Department of Pathology School of Basic Medical ScienceFudan UniversityShanghai 200030China

Acute kidney injury(AKI) is a significant clinical complication with a substantial impact on morbidity and mortality, for which therapeutic options remain limited. The Hippo signaling pathway is an evolutionarily conserved pathway implicated in cell proliferation, dedifferentiation, and apoptosis via phosphorylation and inactivation of its downstream effectorsYes-associatedprotein(YAP)/transcriptional co-activator with PDZ-binding motif(TAZ). Recent studies have revealed that the Hippo pathway plays a pivotal role in the pathogenesis and repair of AKI. The Hippo pathway can mediate renal dysfunction through modulation of mitochondrial apoptosis under AKI conditions. Transient activation of YAP/TAZ in the acute phase of AKI may benefit renal recovery and regeneration, whereas persistent activation of YAP/TAZ in severe AKI may lead to maladaptive repair and transition to chronic kidney disease. This review aims to summarize recent findings on the associations between the Hippo pathway and AKI and to identify new therapeutic targets and strategies for AKI.
