Zhen Wang,Xiansong Liu,Xucai Kan,Ruiwei Zhu,Wei Yang,Qiuyue Wu,Shengqiang Zhou 한국물리학회 2019 Current Applied Physics Vol.19 No.8

The flattening of FeSiAl soft magnetic powder was achieved by ball milling process, and MnZn/FeSiAl composite magnetic powder core was prepared by press molding. The effect of different coating amount of MnZn ferrite on the soft magnetic properties of FeSiAl was studied. At the same time, the optimal stress-relieving annealing temperature of the composite magnetic powder core is revealed. The results showed that the addition of MnZn ferrite affected the magnetic properties such as saturation magnetization (Ms), initial permeability (μi) and power loss (Pcm) of FeSiAl soft magnetic. With the increase of MnZn ferrite addition content, the saturation magnetization of composites decreased gradually, and the magnetic permeability increased first and then decreased, and the loss decreased first and then increased. When the addition content of MnZn ferrite was 5%, the permeability reached the maximum, which was 28.1% higher than that of the pure FeSiAl magnetic powder core under the same conditions. At the same time, the loss was the lowest, which was 13.3% lower than the pure FeSiAl powder core under the same conditions. When the annealing temperature is around 650 °C, the magnetic powder core has the largest magnetic permeability and the lowest loss.

Antiglycation and Antioxidant Properties of Soy Sauces

Changwe Mashilipa,Qiuyu Wang,Mark Slevin,Nessar Ahmed 한국식품영양과학회 2011 Journal of medicinal food Vol.14 No.12

Diabetes-induced hyperglycemia increases formation of advanced glycation end products (AGEs) and metalcatalyzed production of free radicals. This study compared the antioxidant capacities of dark and light soy sauces of different brands and investigated their abilities to inhibit AGEs and whether their mechanism of action was pre- or post-Amadori or involved chelation of transition metals. The antioxidant capacities of soy sauces were compared using the 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) method and by measuring their total phenolic contents. Model proteins (lysozyme, albumin)were glycated using fructose with or without soy sauces with subsequent analysis of cross-linked AGEs by sodium dodecyl sulfate–polyacrylamide gel electrophoresis. The effect of soy sauces on pre- and post-Amadori inhibition of AGEs was investigated by measuring fructosamine and AGEs following reincubation of ribose-glycated (ribated) lysozyme, respectively. Dark soy sauces had higher antioxidant capacities and phenolic content and were more effective inhibitors of post-Amadori–derived cross-linked AGEs. However, light soy sauces were more effective at inhibiting fructosamine and had more potent metal chelation properties. This study reports the antiglycation properties of soy sauces, but further studies are required to determine the constituents responsible for this effect and whether soy sauce consumption can reduce oxidative stress and AGEs in diabetic subjects.

Polymerized Ionic Liquid for the Regulation of Phase Structure of PLA/PCL Blends

Yiyang Zhou,Qiuyue Meng,Ping Wang,Haibing Wei,Pei Xu,Yunsheng Ding 한국고분자학회 2022 Macromolecular Research Vol.30 No.9

Polymerized ionic liquid containing block structure (PIL) has been used as regulator for the phase structure of poly(lactide) (PLA)/poly(ε-caprolactone) (PCL) blends. The phase structure, crystallization, rheology behavior and mechanical properties of PLA/PCL and PLA/PCL/PIL blends were systematically investigated. PIL could be located in PCL phase or at the PLA/PCL interface, enhancing the interaction between polymer components. The crystallization ability of PLA and PCL was simultaneously enhanced with the addition of PIL, since the plasticization effect of ionic moiety and PEO segments in PIL as well as the nucleation effect of PIL-formed ionic cluster. When PIL content was 0.5 wt%, the PLA/PCL/0.5PIL blend system exhibited much better mechanical properties than additivefree PLA/PCL blend. But as PIL contents increased, the significantly change in viscosity ratio between PLA and PCL would lead to obviously change in phase structure of PLA/PCL blend, thus the mechanical properties of the blends would be degraded.

To address problems associated with the potential toxicity of sludge when it is applied in land utilization, this study investigated the variations by which activated sludge becomes toxic when fed with wastewater containing mixed chlorophenols, and compared variations in sludge toxicity due to inputs of mixed chlorophenols and single chlorophenol groups. In this study, 4-chlorophenol (4-CP), 2,4,6-trichlorophenol (2,4,6-TCP) and mixed chlorophenols which consist of both 4-CP and 2,4,6-TCP were studied in sequencing batch reactors (SBR). The results indicate that in 0-30 d, the toxicity of sludge fed with mixed chlorophenols is higher than that of sludge fed with single chlorophenol groups. During 50-100 d, the toxicity of sludge fed with mixed chlorophenols ranged between two single chlorophenol groups. EPS and protein in EPS had a significant relationship with sludge toxicity, but there was no significant relationship between polysaccharide in EPS and sludge toxicity.

MondoA Is Required for Normal Myogenesis and Regulation of the Skeletal Muscle Glycogen Content in Mice

Hui Ran,Yao Lu,Qi Zhang,Qiuyue Hu,Junmei Zhao,Kai Wang,Xuemei Tong,Qing Su 대한당뇨병학회 2021 Diabetes and Metabolism Journal Vol.45 No.3

Background: Skeletal muscle is the largest tissue in the human body, and it plays a major role in exerting force and maintaining metabolism homeostasis. The role of muscle transcription factors in the regulation of metabolism is not fully understood. MondoA is a glucose-sensing transcription factor that is highly expressed in skeletal muscle. Previous studies suggest that MondoA can influence systemic metabolism homeostasis. However, the function of MondoA in the skeletal muscle remains unclear. Methods: We generated muscle-specific MondoA knockout (MAKO) mice and analyzed the skeletal muscle morphology and glycogen content. Along with skeletal muscle from MAKO mice, C2C12 myocytes transfected with small interfering RNA against MondoA were also used to investigate the role and potential mechanism of MondoA in the development and glycogen metabolism of skeletal muscle. Results: MAKO caused muscle fiber atrophy, reduced the proportion of type II fibers compared to type I fibers, and increased the muscle glycogen level. MondoA knockdown inhibited myoblast proliferation, migration, and differentiation by inhibiting the phosphatase and tensin homolog (PTEN)/phosphoinositide 3-kinase (PI3K)/Akt pathway. Further mechanistic experiments revealed that the increased muscle glycogen in MAKO mice was caused by thioredoxin-interacting protein (TXNIP) downregulation, which led to upregulation of glucose transporter 4 (GLUT4), potentially increasing glucose uptake. Conclusion: MondoA appears to mediate mouse myofiber development, and MondoA decreases the muscle glycogen level. The findings indicate the potential function of MondoA in skeletal muscle, linking the glucose-related transcription factor to myogenesis and skeletal myofiber glycogen metabolism.
