Jin Xining,Zhai Huijie,Wang Pingxi,Zhang Xiaoxiang,Wu Xiangyuan,Zhang Huaisheng,Chen Shilin,Huang Zhongwen 한국유전학회 2022 Genes & Genomics Vol.44 No.8
Background: There were significant differences in the change of moisture content and grain composition at the late stage of grain development among different maize varieties, but the regulation mechanism is not clear. Objective: To explore the key genes causing the variation in physiological traits of two typical maize inbred lines in late grain development. Methods: The grains at different development stages were selected as materials to determine the content of water, sucrose, starch and ABA. Transcriptomic and proteomic analysis of the materials were performed to screen relevant genes. Results: The grain dehydration rate and the content of sucrose, starch and ABA were showed significant differences between two varieties in the late stage of grain development. The enrichment analysis of common differentially expressed genes (proteins) showed that most of the genes (proteins) were enriched in the extracellular region. The downregulated genes were mainly concentrated in carbohydrate metabolism and lipid metabolism, while the upregulated genes were mainly in response to stress. Furthermore, this study also identified many key candidate genes (dehydrin genes, pathogenesis-related genes, sucrose synthase and secondary metabolites related genes) related to late grain development of maize. Conclusions: The suggested genes related to late grain development of maize can be candidates for further functional study.
Effect of Sn on Plastic Deformation Ability of Fe–Si–B–P–Sn bulk Metallic Glasses
Xiaoyu Wu,Xining Li,Xue Li,Shengli Li 대한금속·재료학회 2023 METALS AND MATERIALS International Vol.29 No.12
Fe-based bulk metallic glasses have the advantages of high strength and low coercivity. However, their plastic deformationability is negligible. Therefore, in this study, Sn was added to a Fe–Si–B–P bulk metallic glass matrix to study its influence onthe formation and plastic deformation ability of Fe–Si–B–P bulk metallic glasses. The results showed that the mixing enthalpyof Sn was less than that of Fe and other metal-like atoms, which caused Sn atoms to separate from Si-, B- and P-centeredclusters, resulting in metal-like clusters not occupying adjacent positions and the voids between clusters being occupied bySn atoms. With increasing Sn, the metal-metal bonds of the linked clusters increased and the macroscopic performance wasmanifested in an improvement in the plastic deformation ability. With 0.3 at% Sn addition, the alloy system showed the bestplastic deformation ability increasing from 0.7 to 2.2% and the yield strength of 3150 MPa.

<P>Through a simple room-temperature photoreduction process, this letter conformally replicates 3D submicrometer structures of wing scales from two butterfly species into Ag to generate practical surface-enhanced Raman scattering (SERS) substrates. The Ag replicas of butterfly scales with higher structural periodicity are able to detect rhodamine 6G at a low concentration down to 10(-9) M, which is three orders of magnitude lower than the detectable concentration limit of using quasi-periodic Ag butterfly structures. This result presents a way to select suitable scale morphologies from 174,500 species of Lepidopterans to replicate, as consumable SERS substrates with low cost and high reproducibility.</P>

Purpose The influence of fasting blood glucose (FBG) and cholesterolemia primary liver cancer (PLC) in China was analyzed via a large prospective cohort study based on a community population, and the combined effects between them were investigated. Materials and Methods Overall, 98,936 staff from the Kailuan Group who participated in and finished physical examinations bet-ween 2006 and 2007 were included in the cohort study. Their medical information was collected and they were followed up after examination. The correlations of serum FBG or total cholesterol (TC) with PLC were analyzed. Then, we categorized all staff into four groups: normal FBG/non-hypocholesterolemia, normal FBG/hypocholesterolemia, elevated FBG/non-hypocholesterolemia, elevated FBG/hypocholesterolemia, and normal FBG/non-hypocholesterolemia was used as a control group. The combined effects of elevated FBG and hypocholesterolemia with PLC were analyzed using the Age-scale Cox proportional hazard regression model. Results During 1,134,843.68 person-years follow-up, a total of 388 PLC cases occurred. We found the elevated FBG and hypocholesterolemia increase the risk for PLC, respectively. Compared with the non-hypocholesterolemia/normal FBG group, the risk of PLC was significantly increased in the non-hypocholesterolemia/elevated FBG group (hazard artio [HR], 1.19; 95% confidence interval [CI], 0.88 to 1.62) and hypocholesterolemia/normal FBG group (HR, 1.53; 95% CI, 1.19 to 1.97), and in the hypocholesterolemia/elevated FBG group (HR, 3.16; 95% CI, 2.13 to 4.69). And, a significant interaction effect was found of FBG and TC on PLC. All results were independent from the influence of liver disease. Conclusion Elevated serum FBG and hypocholesterolemia are risk factors for PLC, especially when combined. Thus, for the prevention and treatment of PLC, serum FBG and TC levels should be investigated.

Electromagnetic environment assessment is an important step in the design process of a wireless power transfer (WPT) system to ensure that it complies with electromagnetic radiation standards. Electromagnetic environment assessment usually requires an effective magnetic field analytical model. However, the traditional magnetic field analytical model does not consider the impact of shielding media on the external electromagnetic environment of the WPT system. Therefore, based on subdomain analysis technology in the Cartesian coordinate system, this paper establishes a three-dimensional magnetic field analytical model that comprehensively considers coil parameters, passive shielding media, and active shielding coils. To solve the problem of re-dividing various regions when migrating, a misalignment parameter was introduced in the modeling analysis. In addition, an efficient active shielding coil modeling method is proposed based on electromagnetic theory, which reduces the analytical calculation time of the model. Finally, a 200 W WPT system electromagnetic environment assessment platform that includes both active and passive shielding is built. Under different misalignment and transmission distance conditions, the maximum error of the model calculation and finite element analysis (FEA) is less than 3%, and the maximum error of the model calculation and measurement values is less than 8%. Research results verify the accuracy of the proposed three-dimensional magnetic field analytical model and the effectiveness of the shielding measures. This paper lays a theoretical foundation for the electromagnetic environment assessment of WPT systems and the pre-design of shielding measures.
