The individual dose of PCB-153 at this mixture dose was approximately 254 μg/kg/day.
The lowest mixture dose was equivalent to the sum of the chemicals' individual NOAELs for retained nipples (NR NOAEL), the middle dose was 5-fold higher, and the highest dose was 10-fold this value.
For the TEF mixture, doses were formulated for comparison with the 10, 22, 46, and 100 ng/kg TCDD group by using the WHO TEFs of 1.0 for TCDD, 0.1 for PCB-126, and 0.5 for PeCDF.
For the mixture, the dose is an additive function of the component congener doses and the ratios of their ED50 values to that of TCDD (Toyoshiba et al. 2004).
The absolute doses of each chemical in the stock solution (i.e., the highest mixture dose examined) were equal to 33% of the ED30 for the chemical [see also Supplemental Material, Table 1 (doi:10.1289/ehp.0900667. S1 via http://dx.doi.org/)].
"The recommended dose is a 50 50 mixture of xenon and oxygen, inhaled for a few minutes, ideally before going to bed," reported the Economist.

For example, at the second highest mixture dose there was a 38% decrease in T4.
Each vaccine dose was a lyophilized mixture of the four lipopeptides that was reconstituted with 0.5 ml of a 5% isotonic glucose solution and injected either intradermally (0.1 ml, 100 µg of each peptide) or intramuscularly (0.5 ml, 500 µg of each peptide).
Since the highest dose of individual compounds resulted in mortality, this dose was not employed for mixture studies.
