While existing route planning techniques for public transit networks are efficient in finding optimal routes, we argue that users could be confused by these theoretical optimal yet impractical routes. To improve user satisfaction, we develop PARTNER - a practical route planning system that can provide users with options to take the next best route if they(More)
The objective of this study was to evaluate the effects of polymerized porcine hemoglobin (pPolyHb) on hemodynamic stability and oxygen delivery in a rat model of hemorrhagic shock. Rats underwent controlled hemorrhage, resulting in the loss of 65% of their blood volume in 90 minutes. The results showed that pPolyHb was superior to hetastarch and saline,(More)
The effects of polymerized porcine hemoglobin (pPolyHb) on hemodynamic stability and maintenance of mesenteric microvascular function were explored in a rat model of hemorrhagic shock (HS). Following controlled hemorrhage, rats were infused with equal volumes of either pPolyHb, hetastarch (HES), or red blood cell (RBC). The results showed that pPolyHb was(More)
Polymerized porcine hemoglobin (pPolyHb), which was synthesized from chemically modified porcine hemoglobin, can carry and deliver oxygen to tissues in addition to restoring intravascular volume. Assessment of the inflammatory response generated in the host is a part of the overall safety evaluation of pPolyHb. In this study, we measured the levels of(More)
The objective of this study was to investigate the recovery ability of polymerized porcine hemoglobin (pPolyHb) in a rat model of acute anemia caused by normovolemic hemodilution (ANH). After the ANH procedure, rats were infused with either pPolyHb or red blood cells. The results showed pPolyHb could carry a sufficient amount of oxygen to the tissues to(More)
