Hemodynamic evaluation of a new pulsatile flow generation method in cardiopulmonary bypass system

Вестник трансплантологии и искусственных органов, 2019
This paper proposes a new method of generating pulsatile flow using non-pulsating pumps (NPP) without modulating the rotation speed of the pump rotor. At the initial stage, this method was proposed for NPP-based cardiopulmonary bypass (CPB) systems.

The influence of portal blood upon lipid metabolism in normal and diabetic dogs and baboons [PDF]

, 1975
It has been reported that hyperlipidemia can be alleviated in human beings with an end to side portacaval shunt. Understanding the mechanism of the effect has important implications, including the possibility of devising other ways of lowering serum ...
