Frontiers of Agricultural Science and Engineering 2017, Volume 4, Issue 3, Pages 342-352 doi: 10.15302/J-FASE-2017162

Abstract: Neutrophils are vital components of defense mechanisms against invading pathogens and are closely linked with the individual antiviral capacity of pigs and other mammals. Neutrophilia is a well-known clinical characteristic of viral and bacterial infections. Using Affymetrix porcine genome microarrays, we investigated the gene expression profiles associated with neutrophil variation in porcine peripheral blood before and after polyriboinosinic-polyribocytidylic acid stimulation. Transcriptomic analysis showed 796 differentially expressed genes (DEGs) in extreme response (ER) pigs and 192 DEGs in moderate response (MR) pigs. Most DEGs were related to immune responses, included , , , , , , , and . Gene ontology analysis indicated that the DEGs of both ER and MR pigs were involved in common biological processes, such as cell proliferation, growth regulation, immune response, inflammatory response and cell activation. The ER and MR groups also showed differences in DEGs involved in biological processes. DEGs involved in cell division and cell cycle were specifically found in the ER pigs, whereas DEGs involved in cell migration were specifically found in the MR pigs. The study provides a basic understanding of the molecular basis for the antiviral capacity of pigs and other mammals.

Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 4, Pages 448-455 doi: 10.1007/s11709-014-0262-x

Abstract: Rock mass classification system is very suitable for various engineering design and stability analysis. classification method is confirmed by Japan Highway Public Corporation that this method can figure out either strength or deformability of rock mass, further appropriating the amount of rock bolts, thickness of shotcrete, and size of pitch of steel ribs just after the blasting procedure. Based on these advantages of method, in this study, according to data of five deep and long tunnels in Iran, two equations for estimating the value of method from and classification systems were developed. These equations as a new method were able to optimize the support system for and classification systems. From classification and its application in these case studies, it is pointed out that the method for the design of support systems in underground working is more reliable than the and classification systems.

Presence and Antimicrobial Susceptibility of RE-cmeABCi>-Positive Campylobacteri> Isolated Article

Dejun Liu, Weiwen Liu, Xing Li, Hong Yao, Zhangqi Shen, Yang Wang, Jianzhong Shen

Engineering 2020, Volume 6, Issue 1, Pages 34-39 doi: 10.1016/j.eng.2019.10.013

Abstract:

Campylobacter spp. (C. spp.) are the leading cause of human gastroenteritis worldwide. RE-CmeABC is a newly identified resistance-enhancing multidrug efflux pump of C. spp. that confers high-level resistance to fluoroquinolones, phenicols, macrolides, and tetracyclines, all of which are critical drugs in both human and veterinary medicine. In this study, we analyzed the presence and antimicrobial susceptibility of RE-cmeABC-positive Campylobacter isolates of food-animal origin from three representative regions (Shandong, Shanghai, and Guangdong) in China over three successive years, from 2014 to 2016. A total of 1088 Campylobacter isolates (931 C. coli and 157 C. jejuni) were recovered from the RE-cmeABC screening. We detected 122 (11.2%) RE-cmeABC-positive isolates of chicken origin, including 111 (70.7%) C. jejuni and 11 (1.2%) C. coli. This multidrug efflux pump is more prevalent among C. jejuni than C. coli. The level of resistance was significantly different in 111 RE-cmeABC-positive C. jejuni versus 46 RE-cmeABC-negative C. jejuni for florfenicol, clindamycin, and erythromycin (P < 0.05), but not for ciprofloxacin (CIP), tetracycline (TET), and gentamicin. However, the isolates harboring RE-cmeABC could shift the minimum inhibitory concentration distribution to the higher range for CIP and TET. Pulsed-field gel electrophoresis (PFGE) analysis suggested that horizontal transmission might be involved in the dissemination of RE-cmeABC in Shanghai and Guangdong, while clonal expansion was predominant in Shandong. Three isolates shared the indiscriminate PFGE types of RE-cmeABC-positive C. jejuni isolates in Shanghai and Guangdong, and four isolates in Shanghai and Shandong. Our study suggests the possibility of a wide dissemination of RE-cmeABC in Campylobacter of food-animal origin, which would pose a significant threat to public health.
