Botha, Ishaq Ahmad, M. Maaza, Fabian I. EzemaAbstractBiogenic synthesis of silver nanoparticles (AgNPs) was conducted via an aqueous extract of fresh leaf of Gongronema Latifolium (FLGL) an herbaceous flowering plant as a fuel agent. The effects of different AgNO3 concentration with the fixed volume of FLGL on the properties of the formulated AgNPs were investigated. Also, the antibacterial activity AgNPs formed was observed through the solid ...

Authors: Monini M, Ostanello F, Vignolo E, Pagani E, Gamper S, Spertini S, Masi E, Rabini M, Stenico A, Poznanski E, Di Bartolo I Abstract In October 2017, two outbreaks of gastroenteritis (GE) occurred among patrons of a cafeteria in Italy in one week. Virological and bacteria investigations on stool samples, environment and food were conducted to identify the infectious agents and the possible source of infection. Forty-five cases occurred in the two outbreaks, including 13 laboratory-confirmed cases of norovirus GI. Nine staff members were interviewed, six were confirmed positive for NoV GI and 3 experienced GE ...

Publication date: Available online 15 July 2019Source: PlasmidAuthor(s): Shao-Heng Bao, Dong-Yi Zhang, Er MengAbstractPinene is a monoterpene with wide industrial applications, especially as a promising high energy-density jet fuel. Traditional production of pinene on an industrial scale is material consumptive and has a low yield. As an alternative, microbial organisms have been engineered though advanced synthetic biological techniques to produce a variety of heterologous products, including pinene. Here, we investigated the stability of genetic circuits encoding the pinene producing pathway during fermentation and its r...

Publication date: September 2019Source: Fish &Shellfish Immunology, Volume 92Author(s): Dinglong Yang, Yijing Han, Lizhu Chen, Ruiwen Cao, Qing Wang, Zhijun Dong, Hui Liu, Xiaoli Zhang, Qianqian Zhang, Jianmin ZhaoAbstractIn the present study, a macin was cloned and characterized from clam Venerupis philippinarum (designed as VpMacin). The full-length cDNA of VpMacin was of 579 bp, encoding a peptide of 87 amino acids with the predicted molecular weight of 9.7 kDa. Analysis of the conserved domain suggested that VpMacin was a new member of the macin family. In non-stimulated clams, VpMacin transcripts exhibited diffe...

We focused on a transaminase-mediated cascade for bioamination from an alcohol or aldehyde. The cascade can convert an alcohol or a...

We report a rapid method for synthesis of zeolitic imidazolate framework 8 (ZIF-8)-decorated graphene oxide (GO) composites (ZGO) with good antibacterial properties. The ZGO composites were synthesized at room temperature with low GO to metal salt ratios. The samples were characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, thermal gravimetric analysis, and surface area analysis. The characterization results show that ZIF-8 with a size of approximately 120 nm is successfully decorated on the surface of GO sheets with the host ZIF-8 framework maintained in the s...

In conclusion, this is the first study that describes the dynamics of plasma ecDNA and DNase activity in early sepsis in detail. Our study is the basis for further studies focused on the timing of exogenous DNase treatment in sepsis. Additional studies will be needed to monitor plasma ecDNA in later time points that are more clinically relevant.
