Although synthesized in the same pituitary gonadotropes, the secretion profiles of lutropin (LH) and follitropin (FSH) differ. LH is secreted through a regulated pathway and associated with a bolus release at mid-estrous cycle. In contrast, the majority of FSH is secreted constitutively with an incremental increase until ovulation. Both share an identicalα subunit, and thus theβ subunit contains determinants for sorting into the regulated pathway. Previously, we demonstrated that a hydrophobic carboxyl-terminal heptapeptide of the LHβ subunit (Leu-Ser-Gly-Leu-Leu-Phe-Leu), not found in the FSHβ subunit, influences the intracellular behavior of the LH dimer. To test the hypothesis that the peptide contributes …

Current exercises recommended during pregnancy are prescribed at the same intensity as the general adult population, 3-6 METs. It is unclear whether these MET values can be applied to the pregnant population. Purpose: To determine energy expenditure of pregnant women while participating in three exercises (walking, stationary biking, and prenatal aerobics) during the second and third trimesters. And second, to determine whether the energy expenditure of the exercises would change from the second to third trimester. Methods: Participants were 3 women, ages 23-32, in their second trimester (weeks 14-26) of pregnancy at commencement of the study. Subjects reported to the …
