Light quality regulates plant growth and photosynthesis, the drivers of fruit quality, and light quality can be controlled by colored light-quality selective plastic films in field production. To identify the optimal color of plastic film for high-quality strawberry (Fragaria × ananassa) fruit production, plant growth, photosynthetic abilities, and fruit qualities were investigated under transparent (T), red (R), yellow (Y), green (G), blue (B), and purple (P) films. The R film showed the maximum promoting effects on leaf area, petiole length, leaf biomass, and shoot biomass. The R film improved photosynthetic abilities by increasing photosynthetic pigment content, quantum yield (φPo), electron transfer (Ψo and φEo), the density of reaction centers (RC/CSm), and the photosynthetic performance index (PIabs), and by decreasing the dissipation of absorbed solar energy as heat (φDo), while varied reverse effects were detected under other films. For fruit qualities, the R film also improved fruit weight and the content of total sugar, anthocyanin, and soluble protein. Therefore, the R light-quality selective plastic film should be suitable for strawberry production due to the promoting effects on plant growth, photosynthetic abilities, and fruit weight and quality.

Cermet materials are important new engineering materials with combined advantages of ceramics and metals. In this study,Al2O3/Al cermet materials were prepared through powder metallurgy. The effect of sintering technology on the properties ofAl2O3/Al cermet materials was analyzed as basis for preparing high-performance cermet materials. Results showed that whenthe sintering temperature was increased from 700 oC to 1000 oC under holding time for 1 h, the densification degree and hardnessof Al2O3/Al cermet materials decreased and the electric resistivity increased. In the microstructure of Al2O3/Al cermet materials,Al particles were larger and continuously distributed, whereas the Al2O3 particles were smaller and discontinuously distributed. When the holding time was increased under sintering temperature of 700 oC, the densification degree and hardness of Al2O3/Alcermet materials also increased, and the electric resistivity decreased. When 25 wt% Al2O3/Al cermet materials were sintered at700 oC for 3 h, the densification degree was higher, with hardness of 2203 HV and electric resistivity of 0.0159 Ω • m.

The neuronally expressed developmentally downregulated 4 (NEDD4) gene encodes a ubiquitin ligase that targets the epithelial sodium channel for degradation and has been implicated in tumor growth in various cancers. Hence, in this study, we intended to characterize the functional relevance of the NEDD4-mediated Kruppel-like factor 8/microRNA-132/nuclear factor E2-related factor 2 (KLF8/miR-132/NRF2) axis in the development of bladder cancer. NEDD4 and KLF8 were overexpressed in bladder cancer tissues and were associated with poorer patient survival rates. In bladder cancer cells, NEDD4 intensified the stability and transcriptional activity of KLF8 through ubiquitination to augment cell viability and migratory ability. Our investigations revealed that NEDD4 promotes the binding of KLF8 to the miR-132 promoter region and inhibits the expression of miR-132. KLF8 inhibited the expression of miR-132 to augment the viability and migratory ability of bladder cancer cells. Furthermore, miR-132 downregulated the expression of NRF2 to restrict the viability and migratory ability of bladder cancer cells. In addition, in vivo findings verified that NEDD4 regulates the KLF8/miR-132/NRF2 axis by accelerating tumor growth and lung metastasis. In conclusion, this study highlights NEDD4 as a potential therapeutic target against tumor recurrence and metastasis in bladder cancer.
