Researchers measured levels of 11-deoxycortisol, 17-hydroxypregnenolone, 17-hydroxyprogesterone, pregnenolone and androstenedione via liquid chromatography-mass spectrometry, and levels of ...

FROM the moment of conception an interplay of biochemical processes ensures the growth and development of the fetus and its placenta. Such an interplay must function under an intricate system of ...

We measured cortisol, 11-deoxycortisol, 17-hydroxyprogesterone, 17-hydroxypregnenolone, dehydroepiandrosterone sulfate, and ACTH in 40 extremely low birth weight infants enrolled in a study of low ...

The data suggest that a pathway is possible which by-passes progesterone to form androgens: pregnenolone→17α-hydroxypregnenolone → 17 α-hydroxyprogesterone→androstenedione. This report ...
