BACKGROUND Neuroprotection from therapeutic hypothermia increases when combined with the anaesthetic gas xenon in animal studies. A clinical feasibility study of the combined treatment has been successfully undertaken in asphyxiated human term newborns. It is unknown whether xenon alone would be sufficient for sedation during hypothermia eliminating or(More)
As the optical penetration depth and thermal diffusion effect are small, shear waves and longitudinal waves generated by a laser pulse in thermoelastic regime are generally weak in metallic materials. The method of laser ultrasonic is rarely applied to inspect the inner cracks. In this paper, phased array laser ultrasonic is developed to focus and steer(More)
We describe the synthesis and positive inotropic evaluation of a series of 2-(4-substitutedbenzylpiperazin-1-yl)-N-(2-oxo-2,3-dihydrobenzooxazol-6-yl)acetamides by measuring left atrial stroke volume in preparations of isolated rabbit hearts. Several compounds were developed from and showed favorable activities compared with the standard drug milrinone.(More)
