[Characteristics of fish aggregation devices (FADs)and associated tuna schools behavior in Chinese tuna purse seine fishery.].

The use of fish aggregation devices (FADs) can increase catchability of tuna purse seine for associated tuna schools. In the past decades, large scale deployments of FADs have drawn the international attention due to their negative effects on the marine environment. Finding a FAD design ecologically and economically compatible has therefore become a challenge for tuna purse seine fishe-ry.

Propofol attenuates hydrogenperoxide-induced apoptosis in human umbilical vein endothelial cells via multiple signaling pathways.

Background: Propofol has been reported to protect vascular endothelial cells against oxidative stress. In this study we investigated its effect on hydrogen peroxide (H2O2)-induced apoptosis of human umbilical vein endothelial cells (HUVECs) and examined the possible signaling pathways.

Methods: HUVECs were pretreated with propofol (1, 5, 25, and 50 µM) for 30 min and then co-incubated with 0.

Propofol attenuation of hydrogen peroxide-induced injury in human umbilical vein endothelial cells involves aldose reductase.

Propofol is a widely used intravenous anesthetic agent with antioxidant/antiapoptotic properties. Aldose reductase (AR) has been implicated in oxidative stress and apoptosis in endothelial cells. AR inhibition may protect cells from cardiovascular injury.
