At pH 2 and T = 75 °C for 7 min, only Se(IV) was able to form the piazselenol complex with 4-nitro-o-phenylenediamine.
Figures 5 and 6 show micro-XRF spectra of skin from mice exposed for either 14 days or 196 days, respectively, to As only, Se only, As + Se, or neither As nor Se (control).
If only SEs or 95% CIs are reported for means and no SDs, the SDs will be calculated as follows: SD=SEM×Square root of sample size.
The greater average LT50 of invasives compared with native species in our study was driven by differences at 24°C, where mortality was only 14.0% (±6.11 SE) for invasives but was 57.8% (±21.20) for natives (t-test, t = 2.649, p = 0.033; Figure 3).
In the first weeks of life, milk is the only source of Se for the calf, but the Se content in the milk is rather low [ 3].
In the first weeks of life, milk is the only source of Se for the calf and insufficient level of Se in the milk may lead to Se deficiency.
Only for Se the concentration scheme used was as follows: 1, 1 × 2.5, and 1 × 5, which corresponded to 0.08, 0.2, and 0.4 μM, in order to avoid the cytotoxicity showed in preliminary experiments by Se concentrations higher than 0.4 μM.
In the Table 2, while "strictly defined" includes only not-for-profit SE, and hybrid SE (both economic and socially oriented) as parts of the spectrum, "broadly defined" includes all the five categories.
The emerging findings clearly favour environmental or an interaction between genetics and environmental factors rather than only genetic factors per se, for it is hard to imagine genetic factors where the effect is delayed to later adult life [ 61].
However, only values for Se and Sp when the test is used on individual serum samples are available (and not pool Se (PSe) and pool Sp (PSp)) (Manufacturer data on file).
