More recent blood concentration data, from NHANES 2001/2, suggest an adult average at 21.7 pg/g TEQ lwt.
Hence, regression equations produced during the eutrophication phase in the late 1980s generally underestimated the Chla concentration corresponding to more recent and lower TN concentrations obtained during the oligotrophication phase.
To explore the nature of this apparent discrepancy, here we tested the performance of RCBS, CAI and RCBSPC against the more recent and larger protein concentration data set of Ishihama et al. The results, summarized in Table 3, are in broad agreement with those obtained in the former data sets.
Although most studies highlight effects at relatively high NP concentrations, more recent approaches document sublethal implications at field-relevant levels particularly over multiple generations (as reviewed in [177]).
In more recent studies, elevated serum concentrations of more acute phase proteins were shown, including sialic acid, α-1 acid glycoprotein, C-reactive protein (CRP) and serum amyloid A (Crook et al 1993; Pickup et al 1997).
In a more recent study, high urinary BPA concentrations were associated with cardiovascular diagnoses, diabetes, and clinically abnormal concentrations of the liver enzymes γ-glutamyltransferase and alkaline phosphatase (Lang et al. 2008).
A more recent study showed that auxin concentrations remain relatively constant over the course of berry development [ 53].
In contrast, some more recent studies found that glucose concentrations are slightly higher in plasma than in serum.
However, more recent data indicate that transcobalamin concentrations elevate only in conditions with macrophage activation (31, 46).
37 More recent data has revealed high concentrations of both maraviroc, a CCR5 antagonist, and raltegravir, an integrase inhibitor, in both the male and female genital tracts.
