Heat shock protein A9 (HSPA9), a member of the heat shock protein family, is a putative receptor for Tembusu virus (TMUV). By using Western blot and co-immunoprecipitation assays, E protein domains I and II were identified as the functional domains that facilitate HSPA9 binding. Twenty-five overlapping peptides covering domain I and domain II sequences were synthesized and analyzed by using an HSPA9 binding assay. Two peptides showed the capability of binding to HSPA9. Dot blot assay of truncated peptides indicated that amino acid residues 19 to 22 and 245 to 252 of E protein constitute the minimal motifs required for TMUV binding to HSPA9. Importantly, peptides harboring those two minimal motifs could effectively inhibit TMUV infection. Our results provide insight into TMUV–receptor interaction, thereby creating opportunities for elucidating the mechanism of TMUV entry.

Service-oriented manufacturing is a trend in the manufacturing industry in the 21st century. Numerous theories related to this trend have been proposed. In particular, three typical theories, namely, industry 4.0, industrial Internet, and cloud manufacturing (CMfg), are discussed in this paper, including their differences. Existing problems in CMfg are analyzed. From the perspective of the service supplier, and by considering former research, three application modes of CMfg are proposed. A 3D printing application mode of CMfg is presented based on the characteristics of 3D printing and discussed in detail. The key technologies of 3D printing in CMfg are explained according to the differences between traditional manufacturing and CMfg.

Interface solar desalination technology is an important green and sustainable strategy to solve the freshwater crisis. Herein, polyaniline (PANI) membranes were prepared by immersion precipitation phase inversion (NIPs) method and using for solar-driven water evaporation. To improve the light absorption rate of the PANI membrane, acid doping modification was carried out to the membrane. The results show that the polyaniline-p-toluene sulfonic acid (PANI-PTSA) membrane modified by p-toluene sulfonic acid (PTSA) has microporous structure, and the hydrophilicity was greatly improved after modification. The water evaporation rate and solar energy conversion efficiency of PANI-PTSA membrane were 1.38 kg/(m2h) and 80.7% under 1 kW/m2 sunlight irradiation, respectively, significantly improved compared to the original membrane. Due to the electrostatic repulsion effect of PANI-PTSA on anion charged SO − 3 , Na+ is separated from Cl−, which reduces the salt crystallization in the evaporator, indicating that PANI-PTSA membrane has certain salt resistance in solar desalination experiments. This work provides a simple method to prepare the PANI-PTSA membrane with high efficiency and salt resistance that has huge potential for practical application of interface solar desalination technology.

In this work, coryphantha elephantidens-like SnO2 with porous structures were prepared successfully by a simple hydrothermal route, through adjusting the temperature of hydrotherm. Its morphology was characterized by Xray diffraction (XRD), scanning electron microscopy (SEM) and Brunauer–Emmett–Teller (BET). Compared to the regular nanospheres, the coryphantha elephantidens-like SnO2 nanospheres had obviously higher gas-sensing response, owing to the special structure with large specific surface area (161.16m2 g−1). It surprised us that the coryphantha elephantidens-like SnO2 sensor could easily distinguish between ethanol and acetone, whose chemical property were similar. Moreover, it also exhibited wide measurement range, fast response speed (less than 10 s) and good repeatability at a low temperature (180 °C) to ethanol. The desirable specific surface area and pore volume were conducive to molecules adsorption and diffusion, which were believed to be the major cause of the improvement of gas sensing performance.

Obesity and diabetes are growing health problems worldwide. In this study, dietary provision of Chinese ginseng (0.5 g/kg diet) prevented body weight gain in high-fat (HF) diet-fed mice. Dietary ginseng supplementation reduced body fat mass gain, improved glucose tolerance and whole body insulin sensitivity, and prevented hypertension in HF dietinduced obese mice. Ginseng consumption led to reduced concentrations of plasma insulin and leptin, but had no effect on plasma adiponectin levels in HF diet-fed mice. Body temperature was higher in mice fed the ginseng-supplemented diet but energy expenditure, respiration rate, and locomotive activity were not significantly altered. Dietary intake of ginseng increased fatty acid oxidation in the liver but not in skeletal muscle. Expression of several transcription factors associated with adipogenesis (C/EBPa and PPARc) were decreased in the adipose tissue of HF diet-fed mice, effects that were mitigated in mice that consumed the HF diet supplemented with ginseng. Abundance of fatty acid synthase (FASN) mRNA was greater in the adipose tissue of mice that consumed the ginseng-supplemented HF diet as compared with control or un-supplemented HF diet-fed mice. Ginseng treatment had no effect on the expression of genes involved in the regulation of food intake in the hypothalamus. These data suggest that Chinese ginseng can potently prevent the development of obesity and insulin resistance in HF diet-fed mice.
