Because our assay was not only a single-point determination of survival, information about growth performance could also be acquired easily.
To reduce the considerable expense and labour required for the titration curves, simplified avidity tests based on single-point determinations using EIAs have been described [ 6, 8- 11].
In a pilot study, we showed that single time point determination of tramadol concentration 4 hours after IV tramadol bolus accurately predicts integral tramadol exposure and hence tramadol metabolism in critically ill adults [2].
The rapid loss of GFP in soybean cotyledonary cells made analysis difficult and this target tissue is completely unsuitable for transient expression analysis using single time point determinations.
Since single time point determinations at 24 h are often used for transient expression analysis using GFP [ 33] and GUS [ 49], loss of transient gene expression as reported here in soybean cotyledonary tissues should be recognized as a potential problem in interpreting results.
As immunoglobulin levels in health vary significantly, interpretation of single-time point determinations of immunoglobulin concentration in the context of sepsis pathobiology is a key challenge.
In addition, single point NH4+-N and PON determinations were made on the control water samples described above, as well as samples from eight additional distinct fecal plumes sampled during this period and a similar operation in July 2008.
For comparisons among animals, single point dilutions were selected following the determination of the linear range of serum antibody binding.
Second, the results of reduced dynamic orbit determination using BDS/GPS code and phase measurements, standalone BDS SPP (Single Point Positioning) kinematic solution and real-time orbit determination using BDS/GPS code measurements are presented and analyzed.
The study employed an exploratory sequential cross-sectional research design that allows data collection at a single point in time, and it is most appropriate for descriptive and determination of relationships between variables (Babbie 2007).
Conversely, air sampling conducted when ventilation rates are atypically high or temperatures are atypically low could lead to an incorrect determination that no actions are indicated based upon a measurement from a single point in time.
