The orphan receptor tyrosine kinase Tie-1 is expressed in endothelial cells and is essential for vascular development. Nothing is known about the signaling pathways utilized by this receptor. In this study we have used chimeric receptors composed of the TrkA ectodomain fused to the transmembrane and intracellular domains of Tie-1, or the related receptor Tie-2, to examine Tie-1 signaling capaci...

Liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 K. The studied systems exhibit two types of liquid-liquid equilibrium (LLE) behavior. The system consisting of benzyl alcohol displays type-1 LLE behavior, while a type-2 behavior is exhibited by th...

This paper presents an algorithm based on multi-objective approach for network reconfiguration. Multiple objectives are considered for reduction in the system power loss, deviations of the nodes voltage and transformers loading imbalance, while subject to a radial network structure in which all the loads must be energized and no branch current constraint is violated. These three objectives are ...

The central aim of supply chain management, to have the right product in the right quantities (at the right place) at the right moment at minimal cost. Advancements in information technologies have enabled major innovations in the reengineering of industry's supply chains, redefining the ways companies operate their supply chains. New ventures have emerged to create values for business partners...

Long’s Interactional Input Hypothesis and Smith’s Input Enhancement Hypothesis hold both foci on Zellig Harris's (1976) formalist approach. Accordingly, the pivotal role of learner’s attention as one of the subcomponents of focus-on-form approach may have confused instruction types. However, whether such learning theories on drawing learners' attention on target language forms suit all types of...

OBJECTIVE To investigate the involvement of Tie-1 and Tie-2, receptor tyrosine kinases required for angiogenesis, in synovial proliferation and angiogenesis of rheumatoid arthritis (RA). METHODS Synovial tissues from 10 patients with RA and three control subjects were analysed by double immunohistochemistry and reverse transcriptase polymerase chain reaction (RT-PCR). RESULTS Expression of ...
