Recent studies have shown that the ferric uptake regulator (Fur) of Edwardsiella tarda (Fur(Et)) shares high sequence identity with the Escherichia coli Fur (Fur(Ec)) at the N-terminal DNA-binding region. In the present study, the functional importance of the C-terminal region of Fur(Et) was investigated. It was found that Fur(Et) bearing deletion of the C-terminal 12 residues still possesses m...

OBJECTIVE Junctional adhesion molecule-C (JAM-C) is an adhesion molecule that has multiple roles in inflammation and vascular biology, but many aspects of its functions under pathological conditions are unknown. Here we investigated the role of JAM-C in leukocyte migration in response to ischemia reperfusion (I/R) injury. METHODS AND RESULTS Pretreatment of mice with soluble JAM-C (sJAM-C), u...

A series of materials was prepared by curing acrylated epoxidized soybean oil (AESO) and dibutyl itaconate (DBI) or ethyl cinnamate (EC) comonomers to provide examples of thermosets with a high proportion of bio-based carbon, in accordance with the principles of green chemistry. The comonomers, representative of cellulose-derived (DBI) or potentially lignin-derived (EC) raw materials, were test...

We have developed a new multienzyme control serum, Seraclear-HE, which was designed to function not only as an accuracy and precision control serum but also as an intermethod calibrator for unifying interlaboratory clinical enzyme data in terms of reference method values. Seraclear-HE contains as analytes the following enzymes of human origin only: aspartate aminotransferase (AST, EC 2.6.1.1) a...

The preservation of vascular endothelial cell (EC) barrier integrity is critical to normal vessel homeostasis, with barrier dysfunction being a feature of inflammation, tumor angiogenesis, atherosclerosis, and acute lung injury. Therefore, agents that preserve or restore vascular integrity have important therapeutic implications. In this study, we explored the regulation of hepatocyte growth fa...

The heparin-binding affinity of the tetrameric extracellular superoxide dismutase (EC-SOD) is a result of the cooperative effect of the heparin-binding domains of the subunits, located in the hydrophilic, strongly positively charged C-terminal ends. EC-SOD C, the high-heparin-affinity type, exposed to immobilized trypsin and plasmin was found to rapidly lose its affinity for heparin, without an...

Atherosclerotic cardiovascular disease is the leading cause of mortality in the Western world. Dysfunction of the mitochondrial respiratory chain and overproduction of reactive oxygen species (ROS) are associated with atherosclerosis and cardiovascular disease. Oxidation increases the atherogenecity of LDL. Oxidized LDL may be apoptotic or nonapoptotic for vascular endothelial cells (EC), depen...

Endothelial cells (EC) synthesize platelet-activating factor (PAF) when stimulated with agonists that bind to cell-surface receptors. We examined events that link receptor binding to synthesis of PAF by EC. Bovine EC stimulated with agonists that interact with specific cell-surface receptors accumulated PAF only in the presence of extracellular calcium. Hormonal stimulation of EC resulted in Ca...
