Kozma, Fruzsina, Robert A. Johnson, Fan Zhang, Changhua Yu, Xianglan Tong, and Alberto Nasjletti. Contribution of endogenous carbon monoxide to regulation of diameter in resistance vessels. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1087–R1094, 1999.— Endogenous carbon monoxide was proposed to subserve vasodepressor functions. If so, inhibition of heme oxygenase may be exp...

Hypertension is the most common medical disorder of pregnancy in the United States, affecting 6% to 8% of pregnant women. It is also a leading cause of maternal and fetal morbidity and mortality worldwide1; approximately 63,000 women die every year because of the maternal hypertensive syndromes preeclampsia and eclampsia.2 Hypertensive disorders also result in fetal complications such as preter...
