Do ovarian Hormones Regulate SP-D Expression in the Mouse Uterus During Estrous Cycle and Early Pregnancy?
Estrogen positively regulates expression of SP-D in the mouse uterus. Progesterone, along with estrogen synergizes SP-D expression, however, when administered alone results in negative regulation.
Circulating residual heparin is commonly presented following cardiac surgery and does not correlate with APTT. Considering that mixing studies normalize APTT in most samples, elevated APTT following CPB may reflect deficiency of coagulation factors or presence of a coagulation inhibitor such as protamine. Further studies are required to confirm this observation.
