To help cleanse your system of this now needless tissue, your body begins to produce a substance called prostaglandin, which, in turn, stimulates powerful uterine contractions.
In addition, endometrial lesions emit high levels of a hormonelike substance known as prostaglandin, which can cause dramatic contractions within the uterus or fallopian tubes.
Older glaucoma drugs like latanoprost and travoprost -- called prostaglandin analogs because they bind to prostaglandins or lipids -- also stimulated lash growth but not as much.
The drug is a synthetic prostaglandin, which is a hormone-like messenger found in both sexes that acts on stomachs, kidneys, blood vessels and the uterus.
Others cells from each patient were subjected to UVR and levels of a pro-inflammatory chemical called prostaglandin-E2 (PGE2) measured.
Older glaucoma drugs like latanoprost and travoprost -- called prostaglandin analogs because they bind to prostaglandins or lipids -- also stimulated lashes but not as much.
