Normothermic Machine Perfusion (NMP) in rat livers extended from 6 to 24 hours
(World Scientific) In a paper published inTECHNOLOGY, a team of researchers from Massachusetts General Hospital (MGH) have demonstrated 24-hour rat liver viability in a normothermic machine perfusion (NMP) system. Rat liver perfusion is an efficient and cost-effective method to study how various pharmacologic agents impact liver parenchyma. (Source: EurekAlert! - Medicine and Health)

What Causes Tachycardia?
Discussion
Tachycardia is a rapid heart rate that is above normal for age and level of exertion. Tachycardia is common, particularly sinus tachycardia due to normally encountered circumstances such as pain, fever or exercise. It is usually a normal physiologic process but sustained tachycardia often indicates a potentially abnormal underlying cause.
Sinus tachycardia has a rapid heart rate with normal P waves and P-R intervals and variations from moment to moment and respiration. Generally it is not over 200 beats/minute. Vagal stimulation can slow the heart rate; this is a gradual slowing, not an abrupt slowing seen in ...
