Hydraulic Pressure Extremes Ratio & Extremes Ratio Efficiencies

Qi Maolin

Strategic Study of CAE 2001, Volume 3, Issue 4,   Pages 73-75

Abstract: applies basic formula to the calculation of a relationship between the hydraulic pressure extremes ratioof hydraulic system and the extremes ratio efficiencies.This relationship shows that the greater the hydraulic pressure extremes ratio is, the lower the extremesratio efficiencies are.The article holds that the hydraulic pressure extremes ratio can be designed and chosen.

Diagnostic evaluation of plasma aldosterone concentration to plasma renin activity ratio in primary aldosteronism

ZHANG Huilan, WANG Daowen

Frontiers of Medicine 2008, Volume 2, Issue 1,   Pages 11-14 doi: 10.1007/s11684-008-0003-4

Abstract: Using the plasma aldosterone concentration to plasma renin activity ratio (PAC/PRA ratio) as the screeninghypertensive patients, we studied the clinical characteristics and the diagnostic value of PAC/PRA ratioOne hundred and twenty-six suspected primary aldosteronism patients whose PAC/PRA ratio was > 25 ng/dLThe PAC/PRA ratio can be considered as a routine screening test in hypertensives, especially resistanthypertensive patients and a high PAC/PRA ratio is an invaluable index in primary aldosteronism diagnosis
