Quorum sensing (QS) is a ubiquitous cell-cell communication mechanism in microbes that coordinates population-level cell behaviors, such as biofilm production, virulence, swarming motility, and bacterial persistence. Efforts to engineer QS systems to take part in metabolic network regulation represent a promising strategy for synthetic biology and pathway engineering. Recently, design, construction, and implementation of QS circuits for programmed control of bacterial phenotypes and metabolic pathways have gained much attention, but have not been reviewed recently. In this article, the architectural organizations and genetic contributions of the naturally occurring QS components to understand the mechanisms are summarized. Then, the most recent progress in application of QS toolkits to develop synthetic networks for novel cell behaviors creation and metabolic pathway engineering is highlighted. The current challenges in large-scale application of these QS circuits in synthetic biology and metabolic engineering fields are discussed and future perspectives for further engineering efforts are provided. © 2020 WILEY-VCH Verlag GmbH & Co.

A wide range of highly functionalized phenols were obtained in good yields including a complex drug molecule, which revealed the high functional group tolerance of this protocol. © 2020 Wiley-VCH Verlag GmbH & Co.

The C-terminus of α2AP is crucial for the initial interaction with plasmin(ogen) and the rapid inhibitory mechanism. Approximately 35% of circulating α2AP has lost its C-terminus (non-plasminogen binding α2AP/NPB-α2AP) and thereby its rapid inhibitory capacity. The C-terminal cleavage site of α2AP is still unknown. A commercially available monoclonal antibody against α2AP (TC 3AP) detects intact but not NPB-α2AP, suggesting that the cleavage site is located N-terminally from the epitope of TC 3AP. OBJECTIVES To determine the epitope of TC 3AP and then to localize the C-terminal cleavage site of α2AP. METHODS For epitope mapping of TC 3AP, commercially available plasma purified α2AP was enzymatically digested with Asp-N, Glu-C, or Lys-N. The resulting peptides were immunoprecipitated using TC 3AP-loaded Dynabeads® Protein G. Bound peptides were eluted and analyzed by liquid chromatography-tandem mass spectometry (LC-MS/MS). To localize the C-terminal cleavage site precisely, α2AP (intact and NPB) was purified from plasma and analyzed by LC-MS/MS after enzymatic digestion with Arg-C. RESULTS We localized the epitope of TC 3AP between amino acid residues Asp428 and Gly439. LC-MS/MS data from plasma purified α2AP showed that NPB-α2AP results from cleavage at Gln421-Asp422 as preferred site, but also after Leu417, Glu419, Gln420, or Asp422. CONCLUSIONS The C-terminal cleavage site of human α2AP is located N-terminally from the TC 3AP epitope. Trichostatin A clinical trial Because C-terminal cleavage of α2AP can occur after multiple residues, different proteases may be responsible for the generation of NPB-α2AP. © 2020 The Authors.

Still, no vascular access site is free of complications and reports of hematoma and pseudoaneurysm formation related to distal radial artery access have been reported in the literature. We present a case of a 71-year-old male who developed an arteriovenous fistula (AVF) involving the distal left radial artery following repeated access of the artery. This rare complication is likely avoidable with a comprehensive understanding of the surrounding anatomy and proper procedural technique, including the routine use of ultrasound for access. © 2020 Wiley Periodicals, Inc.OBJECTIVES Our aim was to verify the alleviation effect of sphingosine-1-phosphate (S1P) in a miniature pig model. MATERIAL AND METHODS Thirty male miniature pigs were randomly separated into 10 groups in our experiment. We administered S1P through the parotid duct in a retrograde fashion 2 hr before irradiation (IR). The salivary flow rate and blood flow rate were tested 20 weeks after IR. The apoptotic level was checked at 12, 24 hr and 7 days post-IR. RESULTS Twenty weeks after IR, the salivary flow rate of the IR-side parotid gland in IR + S1P group can be maintained at about 40% of the non-IR side, while only 20% was maintained in the IR group. The blood flow rate and microvascular density were significantly higher in the IR + S1P group than in the IR group. The apoptotic level and cleaved caspase-3 expression were downregulated in IR + S1P group, and the ratio of Bcl-2/Bax was increased. The blood flow rate and CD31 level were significantly restored at 12, 24 hr and 7 days post-IR. CONCLUSION Sphingosine-1-phosphate may partially alleviate IR-induced parotid dysfunction by decreasing apoptosis of microvascular endothelial cells and maintaining the blood flow rate. © 2020 John Wiley & Sons A/S.

We evaluated final infarct size by cardiac magnetic resonance (CMR) performed 6 months after anterior STEMI treated with remote ischemic conditioning and clinical outcomes up to 3 years after the event. METHODS One hundred and fifteen patients with anterior STEMI were randomized to remote ischemic per-postconditioning (RIperpostC) or sham procedure as adjunct to primary PCI. The primary outcome was myocardial salvage index (MSI) on CMR 6 months after the event. Secondary outcomes were absolute infarct size, left ventricular function, cardiac mortality, major adverse cardiac and cerebrovascular events (MACCE-composite of all-cause mortality, myocardial infarction, readmission for heart failure, ischemic stroke, and target lesion revascularization) and all the individual components of MACCE.
