For o,p′-DDT, the span of measured serum levels became extended toward the high end because of the high measured values in parts of the Canary Islands and Portugal.
We agree that reporting drug exposure (and measured serum levels of drug in experimental animals) would be the optimal measurement upon which to construct dose-response curves and to later correlate with clinical data.
To evaluate the bone resorption activity during leukemia development, we measured serum levels of CTX, a marker of bone resportion, by ELISA.
We measured serum levels of galectin-3 in patients with nonalcoholic fatty liver disease (NAFLD) and examined their association with clinical and histological phenotypes.
Using New York University Women's Health Study subjects, we measured serum levels of prohepcidin with ELISA and hepcidin with mass spectrometry as well as ferritin and soluble transferrin receptor 1 (sTfR1) in 45 normal healthy post-menopausal women over a 1-year period with 2 samples per subject.
Suzuki et al. measured serum levels of HGF and VEGF at 1, 3 and 7 days after bland embolization of HCC.
We measured serum levels of total and free thiamine, thiamine mono di and triphosphate (TMP, TDP and TTP respectively), as well as the erythrocyte transketolase activity and arterial lactate at the time of admission.
We measured serum levels of rheumatoid factor and antibodies against single-stranded DNA (ssDNA) for evidence of autoimmunity.
To test this hypothesis, we measured serum levels of total and gastric mucosa-specific IgM in AID−/− and AID+/+ mice.
To determine whether the changes in bone cellularity and microarchitecture were due to alterations in serum concentrations of calciotropic hormones, we measured serum levels of parathyroid hormone (PTH) and 25-dihydroxy-vitamin D [25(OH D] in Lmna−/− mice and compared them with their WT controls.
Finally, to determine whether the reduction in cell numbers seen in Lmna−/− mice correlated with circulating levels of biomarkers of osteoclastic activity (bone resorption) similar to those used in the clinical setting, we measured serum levels of C-telopeptide (C-Tx) in both null and WT animals.
