Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations. Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels.

The “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle.

MMPs are produced as inactive precursors that require activation by other peptidases, denaturants, or heat. Cell adhesion receptors known as integrins appear to have a role in MMP expression and function. Plasminogen, its activators, and its inhibitors appear to participate in this process. Human endometrium, embryos, and trophoblasts express both uPA and its receptor, and mutations in these have been associated with implantation failure. Polycystic ovary syndrome PCOS is associated with elevated PAI-1 activity, which may contribute to the higher than expected rate of pregnancy loss via this pathway.

Activation of matrix metalloproteinases MMP. This process is inhibited by tissue inhibitors of metalloproteinases TIMPs. Integrin cell adhesion molecules Integrins, one member of a larger family of cell adhesion molecules, have been well studied at the levels of the embryo, trophoblast, and endometrial epithelium and stroma throughout the menstrual cycle and into pregnancy Fig.

They observed that in uteri obtained prior to cycle day 20, all embryos were free-floating in the tubes or uterus, while in uteri obtained after day 21 the embryos were attached to the uterine lining.
