nique and the patient’s enlarged heart geometry.5,6 In addition, echocardiography is not a monitoring device. Right heart catheterization (RHC) is a direct measurement of hemodynamic parameters7 and is a reliable tool for evaluating hemodynamic changes in PH patients. However, the frequent use of RHC is also limited by its invasiveness, infection risk, and expense.8 Therefore, a noninvasive tec...

STUDY OBJECTIVES Parapneumonic effusions are common, and measurement of pleural pH is one of the most useful measurements in assessing the need for tube drainage. Use of pleural pH assumes that a single measurement conveys a representative picture of pH throughout the effusion. Often effusions are multiloculated, and varying concentrations of nondiffusible acids such as lactic acid, if present ...

Rice proteins were extracted from defatted rice flour. Turbidity measurement of supernatants revealed isoelectric points of albumin (pH 4.1), globulin (pH 4.3 and pH 7.9), and glutelin (pH 4.8), at which they were precipitated with 82.3 to 93.2% recovery efficiency. Prolamin did not aggregate and precipitate upon pH adjustment, but was precipitated by acetone. Denaturation temperatures (73.3, 7...
