Enzyme-linked immunosorbent assays (ELISA) were developed for quantifying cytomegalovirus (CMV) and rubella antibodies using a single serum dilution (1/800) in conjunction with a standard curve. A near linear relation was found between the logarithms of absorbance values of sera at a dilution of 1/800 and the titres as determined by an end point dilution ELISA. The reproducibility of the single...

An enzyme-linked immunosorbent assay (ELISA) was developed for the detection of toxoplasma antibodies using a single serum dilution (1:800) in conjunction with a standard curve Antigen was prepared from Toxoplasma gondii cultivated in human cell cultures. A nearly linear relationship was found between the logarithms of the absorbance values of 120 human sera at a dilution of 1/800 and the titre...

A miniature scintillation detector recently designed and constructed in this laboratory can be inserted into the esophagus and under fluoroscopic vision positioned so that radioactivity emitted from the blood in the descending aorta can be detected and a time-concentration curve recorded from which cardiac output can be determined. Twenty simultaneous determinations of cardiac output by the iso...

Here we describe the treatment of the small-angle X-ray Scattering (SAXS) data used during SpeG quaternary structure study as part of the research article "Substrate induced allosteric change in the quaternary structure of the spermidine N-acetyltransferase SpeG" published in Journal of Molecular Biology [1]. These data were collected on two separate area detectors as separate dilution series o...

mHE indicator-dilution method has been widely employed for determination of cardiac output since its introduction by Stewart' and Hamilton and associates.2 The effect of unrecognized recirculation of indicator particles upon the primary indicator time-concentration curve has caused concern as to whether this method may be employed in such conditions as mitral regurgitation3' 4and as to whether ...

A dye dilution and an electric conductivity method for measuring end-diastolic volume and stroke volume of the left ventricle are described, and equations for the calculation of stroke volume are given. When dye is injected "instantaneously" into the left ventricle during diastole, the aortic dye concentration-time curve obtained is a step-like curve and not a smooth curve. The ventricle emptie...

0305-7364/0 * For corre bcgn.grignon. There is still disagreement about whether crop growth rate or soil nitrate concentration control nitrogen absorption by crops under ®eld conditions. The in ̄uence of these factors on the control of N uptake rate was examined in the absence of water stress, using data on dry matter production, above-ground nitrogen accumulation and soil nitrate concentration ...

BACKGROUND & OBJECTIVES Leptospirosis, a zoonosis with a worldwide distribution is an acute febrile illness caused by spirochaetes of the pathogenic Leptospira interrogans. Microscopic agglutination test (MAT), the reference method for diagnosis was successively done to evaluate the modified ELISA which was developed with the recombinant LipL32 antigen for the detection of anti-leptospiral anti...
