A new enzyme linked immunosorbent assay (ELISA) kit which utilizes a monoclonal antibody against prostatic acid phosphatase (PAP) was compared with current radioimmunoassay (RIA) methodology which uses a polyclonal antibody. Both assays are double antibody immunoassays with the major difference being the method of antibody preparation. A study of intrarun precision using control material showed...

An improved method of noninvasive assessment of pulmonary arterial pressure is presented. The already existing radionuclide method for assessment of pulmonary arterial pressure based on right ventricular ejection fraction, although having a relatively good positive predictive accuracy (75 percent), lacks in specificity and correlates only weakly with pulmonary arterial pressure, r = .66. In the...

Procedures have been developed for the determination in serum and urine of 21 drugs which include all of the barbiturates, methyprylon, glutethimide, meprobamate, propoxyphene, methaqualone, primidone, diphenylhydantoin, methadone, codeine, morphine, amphetamine and methamphetamine. The method involves pipeting 1.0 ml of serum or urine into an extraction tube, adding an internal standard togeth...

this experiment conducted to evaluate the effect of different methods of force molting on performance, egg quality of laying hens with one hundred eighty of 52-wk old hy-line layer in completely randomized design with six treatments, five replicates for 90 days. treatments include 1 - feed withdrawal (fw), 2 - 50 percent alfalfa meal: 50 percent layer ration, 3 - 75 percent alfalfa meal: 25 per...

1. Twenty-seven energy and protein balances were done using nine cross-bred (Brown Swiss times Sahiwal) mature bullocks in a series of three balance trials. The bullocks were fed 75, 100 and 125 percent of the metabolizable energy (ME) and digestible crude protein standard values recommended by the (US) National Research Council (1966). Heat production was estimated by indirect calorimetry, by ...

In a survey of 75 dancers (mean age, 24.3 years) in four professional ballet companies, we found that the prevalence of scoliosis was 24 percent and that it rose with increases in age at menarche. Fifteen of 18 dancers (83 percent) with scoliosis had had a delayed menarche (14 years or older), as compared with 31 of 57 dancers (54 percent) without scoliosis (P less than 0.04). The dancers with ...

Background: There has been much discussion amongst automated software defect prediction researchers regarding use of the precision and false positive rate classifier performance metrics. Aim: To demonstrate and explain why failing to report precision when using data with highly imbalanced class distributions may provide an overly optimistic view of classifier performance. Method: Well documente...
