Cerebral ischemia is known to be accompanied by brain edema. This increase in brain tissue water content probably influences the final outcome of an ischemic insult negatively. Despite extensive investigations on different aspects of brain edema, information on edema development during the early recirculation period following ischemia is sparse. We assessed changes in brain water content, as re...

Advances in technology, the desire to minimize blood product transfusions, and concerns relating to inflammatory mediators have lead many practitioners and manufacturers to minimize cardiopulmonary bypass (CBP) circuit designs. The oxygenator and arterial line filter (ALF) have been integrated into one device as a method of attaining a reduction in prime volume and surface area. The instruction...

This work studied the influence of effluent recirculation upon the kinetics of anaerobic degradation of dairy wastewater in the feedless phase of intermittent upflow anaerobic sludge bed (UASB) reactors. Several laboratory-scale tests were performed with different organic loads in closed circuit UASB reactors inoculated with adapted flocculent sludge. The data obtained were used for determinati...

To determine the role of enterohepatic recirculation on its nonlinear elimination, we studied the enteral absorption of mezlocillin in rabbits. Mezlocillin was not substantially absorbed from the stomach or duodenum. We conclude that enterohepatic recirculation does not cause the dose-dependent elimination kinetics of mezlocillin.

In this paper, we propose to regulate the output of an autocatalytic bioprocess by means of a recirculation loop. We show that controlling the recirculation flow rate allows the stabilization of a particular output under a constant or even an unknown input flow. Furthermore, we obtain a convergence in finite time with a smooth feedback law Copyright c ©2005 IFAC.

Conditions for stagnation, recirculation and ventilation potential of the atmosphere were studied in five argentine cities: Resistencia, Cordoba, Buenos Aires, Mar del Plata and Comodoro ́ Rivadavia, located in different regions of the country. Wind run and recirculation factors were calculated for a 24-h transport time using 2 years of hourly surface measurements of wind speed Ž . and direction...

Extracorporeal membrane oxygenation (ECMO) is used as a lifesaving rescue treatment in refractory respiratory or cardiac failure. During venovenous (VV) ECMO, the presence of recirculation is known, but quantification and actions to minimize recirculation after measurement are to date not routinely practiced. In the current study, we investigated the effect of draining cannula design on recircu...
