Basic Study Of Micromachined Dep (dielectrophoretic) Manipulator
… separation in such volumes is still a challenge. DEP (dielectrophoresis) is one of the most widely used methods in handling the microparticles. In this thesis we show that forces generated by nonuniform electric field (DEP) can be used for trapping and separating the microparticles (latex beads). …

Regulation of Wnt signalling pathways by the Dishevelled DEP domain
… Dishevelled (DVL). During canonical (β-catenin dependent) signalling, Dishevelled assembles signalosomes via dynamic head-to-tail polymerization of its DIX domain, which are cross-linked by its DEP domain through a conformational switch from monomer to domain-swapped dimer. The domain-swapped …

Effects of air pollution on vascular thrombosis
… the hypothesis that diesel exhaust particulates (DEP) increase thrombogenicity by impairing the release of tissue plasminogen activator (t-PA) from vascular endothelial cells, thus inhibiting the endogenous fibrinolytic mechanisms that promote thrombus breakdown. The initial aims of this work were …

How does pulmonary exposure to particulate matter predispose the heart to increased injury after myocardial infarction?
… in urban cities is diesel exhaust particulate (DEP). Air pollution has been linked with increased risk of recurrent myocardial infarction (MI) and MI related death (Brook, 2008). This may be due, in part, to effects on atherosclerotic plaque stability and blood clotting tendency. Whether …

Cognitive Style as a Mediator between Parental Psychological Maltreatment and Depression in Adolescent Boys
… parental psychological maltreatment (PM) and depression (DEP) in a sample of adolescent boys. Rose and Abramson (1992) hypothesized that PM affects the development of DEP more than physical abuse (PA) or sexual abuse (SA) due to its unique characteristic of being a direct attack on an …

Optimizing mixer geometries for dielectrophoretic micro-concentrators
Dielectrophoretic (DEP) force, generated by interdigitated electrodes (IDEs), has been utilized to capture bio-particles for microfluidic concentration. However, due to the localized DEP force, DEP-based ,/ -concentrators usually have shallow channels and thus are operated under low flow rates. In …
