Reason for Erratum:
Due to typesetting errors, three mistakes were introduced in the published article.
In the section “7.5. Gut Microbiota, Cecotrophy, Coprophagy”, page 6, left column, 2nd line, should read:
Correct: Rats ingest between 50 and 65% of their feces (82).
Incorrect: Rats ingest between 50 and 65 of their feces (82).
In the section “7.6. Serum Levels in Humans”, page 6, left column, 2nd paragraph, 9th line, should read:
Correct: MS/MS measurements reported that T1AM concentrations in human sera or plasma are far below 1 nM (70). Roy et al. proved excellent stability of deuterated and non-deuterated T1AM in pooled human serum by incubating it for 24 hours at 37°C (57).
Incorrect: MS/MS measurements reported that T1AM concentrations in human sera or plasma are far below 1 nM (57, 70) proved excellent stability of deuterated and non-deuterated T1AM in pooled human serum by incubating it for 24 h at 37°C.
In the section “8. CONCLUSION”, page 6, right column, the last sentence should read:
Correct: One can agree with Hoefig et al. (16), that it will take much less time today compared to earlier discoveries, to unravel the mysteries of the novel T4 metabolite.
Incorrect: One can agree with (16) that it will take much less time today compared to earlier discoveries, to unravel the mysteries of the novel T4 metabolite.
The publisher apologizes for these mistakes. These errors do not change the scientific conclusions of the article in any way.
The original article was updated.
