In this paper, we investigate how detailed tracking of user interaction can be monitored using standard web technologies. Our motivation is to enable implicit interaction and to ease usability evaluation of web applications outside the lab. To obtain meaningful statements on how users interact with a web application, the collected information needs to be(More)
Vascular endothelial growth factor and its receptors, FLK1/KDR and FLT1, are key regulators of angiogenesis. Unlike FLK1/KDR, the role of FLT1 has remained elusive. FLT1 is produced as soluble (sFLT1) and full-length isoforms. Here, we show that pericytes from multiple tissues produce sFLT1. To define the biologic role of sFLT1, we chose the glomerular(More)
In insulin-responsive tissues, insulin is a potent activator of protein kinase B (PKB)-mediated glucose uptake through the facilitative glucose transporter GLUT4. In platelets, glucose uptake is mediated through GLUT3, which is present in plasma (15%) and intracellular alpha-granule (85%) membranes. Here we report the PKB-mediated glucose uptake by(More)
The aim of our study was to investigate the phenomenon of intussusceptive angiogenesis with a focus on its molecular regulation by vascular endothelial growth factor receptor (VEGFR)/platelet-derived growth factor receptor β (PDGFRβ) pathways and biological significance for glomerular recovery after acute injury. Glomerular healing by intussusception was(More)
Eph receptor tyrosine kinases and their ligands (ephrins) have a pivotal role in the homeostasis of many adult organs and are widely expressed in the kidney. Glomerular diseases beginning with mesangiolysis can recover, with podocytes having a critical role in this healing process. We studied here the role of Eph signaling in glomerular disease recovery(More)
When people collaborate remotely, the WWW is part of the shared resources they use together. However, web pages do not offer support for collabo-rative interaction such as viewing or influencing another user's browsing session – additional software needs to be installed for these features. In this paper, we present UsaProxy 2, an HTTP proxy that allows the(More)
Neuropilin1 (Nrp1) is a co-receptor best known to regulate the development of endothelial cells and is a target of anticancer therapies. However, its role in other vascular cells including pericytes is emergent. The kidney is an organ with high pericyte density and cancer patients develop severe proteinuria following administration of NRP1B-neutralizing(More)
