Sentence examples for concentrations of spot from inspiring English sources

VMA concentrations of spot urine samples (2-hour collection) were determined by chomatographic-spectrohotometric assay (FAR, Verona, Italy).

Furthermore, we observed considerable intraday variability in the concentrations of spot samples for MEHHP (51%) and MEP (21%).

More important, we observed a significant within-day variance in BPA urinary concentrations of spot samples collected from the same person.

To assess the impact of creatinine adjustment on the total variance when exposure is categorized from the BPA concentrations of spot urine samples, we built three different models.

We also observed relatively low between-person ICCs (0.09 0.23) for the creatinine-corrected BPA concentrations of spot, first morning, and simulated 24-hr urine collections.

Table 2 also lists the mean creatinine-corrected urinary BPA concentrations of spot, first morning, and simulated 24-hr voids from each participant averaged over the entire study period.

The specificity of each hybridization probe was determined by the co-hybridization of nylon membranes containing different concentrations of spotted cDNA probe: 20 pg, 2 pg, and 0.2 pg of cDNA from each gene were diluted in 3 μl of 20 × SSC buffer, heat-denatured for 5 min by boiling and then quenched on ice.

The specificity of the mammaglobin A and lipophilin B hybridization probes was determined by co-hybridization of nylon membranes containing different concentrations of spotted mammaglobin A and lipophilin B cDNAs in plasmid clones: 1 ng, 100 pg, 10 pg and 1 pg of cDNA from each gene were diluted in 100 ul of 15XSSC buffer, heat-denatured for 5 min by boiling and then quenched on ice.

The creatinine concentration of spot samples ranged from 9.4 to 213.2 mg/dL (mean, 86.6 mg/dL) for FMV samples and from 4.5 to 158.7 mg/dL (mean, 68.6 mg/dL) for non-FMV samples.

The dimension of the spotting pins as well as composition and concentration of spotting reagents were major factors determining the spot size.

However, the differences in urine dilution still explained some of the observed variance in BPA concentrations of the spot samples, because when we accounted for urine dilution, the model fits improved (models B and C vs. A).
