Mitochondrial role in adaptive response to stress conditions in preeclampsia
Preeclampsia (PE) is a pregnancy-specific syndrome, characterized in general by hypertension with proteinuria or other systemic disturbances. PE is the major cause of maternal and fetal morbidity and mortality worldwide. However, the etiology of PE still remains unclear. Our study involved 38 patients: 14 with uncomplicated pregnancy; 13 with early-onset PE (eoPE); and 11 with late-onset PE (lo...
متن کاملEndothelial dysfunction and preeclampsia: role of oxidative stress
Preeclampsia (PE) is an often fatal pathology characterized by hypertension and proteinuria at the 20th week of gestation that affects 5-10% of the pregnancies. The problem is particularly important in developing countries in where the incidence of hypertensive disorders of pregnancy is higher and maternal mortality rates are 20 times higher than those reported in developed countries. Risk fact...
متن کاملCorrelation Between Soluble Vascular Endothelial Growth Factor A, Its Receptor 1 And Response To Chemotherapy In Acute Leukemia In Children
Background and Objective: Vascular endothelial growth factor (VEGF) and its receptors (VEGF-R1 and R2) are major regulators of angiogenesis. This study was designed to assess serum levels of VEGF and VEGF-R1 and their prognostic significance in newly diagnosed childhood acute leukemia. Materials and Methods: For this purpose, VEGF and VEGF-R1 were determined using enzyme linked immuno-sorba...
متن کاملArginase contributes to endothelial cell oxidative stress in response to plasma from women with preeclampsia.
AIMS Preeclampsia is a hypertensive disorder characterized by vascular oxidative stress. Decreased availability of the vasodilator nitric oxide (NO) has been postulated to be involved in the pathophysiology of this disorder. Arginase, an enzyme that competes with nitric oxide synthase (NOS) for l-arginine, not only reduces NO formation but also increases superoxide production by NOS. In placent...
متن کاملEndothelial Nox2 overexpression potentiates vascular oxidative stress and hemodynamic response to angiotensin II: studies in endothelial-targeted Nox2 transgenic mice.
Vascular disease states are associated with endothelial dysfunction and increased production of reactive oxygen species (ROS) derived from vascular NADPH oxidases in both vascular smooth muscle cells (VSMCs) and endothelial cells. Recent evidence suggests an important role for VSMC NADPH oxidases in vascular ROS production. However, it is unclear whether increased NADPH oxidase activity in endo...
