OBJECTIVE To investigate whether angiogenic factors are associated with risk of developing preeclampsia in pregnant women with systemic lupus erythematosus (SLE). METHODS We performed a nested case-control study within a cohort of SLE women with singleton pregnancies. The study included 42 patients with SLE who eventually developed preeclampsia and 75(More)
Leukocyte-platelet interaction is important in mediating leukocyte adhesion to a thrombus and leukocyte recruitment to a site of vascular injury. This interaction is mediated at least in part by the beta2-integrin Mac-1 (CD11b/CD18) and its counter-receptor on platelets, glycoprotein Ibalpha (GPIbalpha). High molecular weight kininogen (HK) was previously(More)
INTRODUCTION AND OBJECTIVES To investigate the role of the 4G/5G polymorphism in the plasminogen activator inhibitor-1 (PAI-1) gene in patients with ST-elevation myocardial infarction (STEMI) aged < or =45 years and its influence on regulation of the plasma PAI-1 concentration. METHODS This case-control study included 127 consecutive patients aged < or(More)
Platelet membrane glycoprotein IIb/IIIa plays an important role in adhesion and platelet aggregation. Polymorphisms of genes in platelet activation and fibrinolysis have been associated with myocardial infarction (MI), however this has not been confirmed by others, and results are still controversial. The aim of this study was to determine the frequency(More)
BACKGROUND The polymorphism Glu298Asp of endothelial nitric oxide (eNOS) gene has been associated with hypertension and coronary artery disease in several populations worldwide, but results are still controversial. We examined the possible association of the Glu298Asp with premature ST elevation myocardial infarction (STEAMI) in young Mexican population. (More)
Previously we demonstrated that domain 5 (D5) of high-molecular-weight kininogen (HK) inhibits neovascularization in the chicken chorioallantoic membrane (CAM) assay and further found that kallikrein cleaved HK (HKa) inhibited FGF2-and VEGF-induced neovascularization, and thus was antiangiogenic. In this study, we sought to demonstrate whether uncleaved HK(More)
BACKGROUND The protein:creatinine ratio in random, untimed urine samples correlates with 24-h protein excretion in pregnant women with and without hypertension. Nevertheless, whether this ratio is appropriate as a screening test for proteinuria is still unclear, in part because of the paucity of large studies. METHODS We measured protein:creatinine ratios(More)
INTRODUCTION Clopidogrel is recommended in addition to aspirin to prevent atherothrombotic events in patients with acute coronary syndromes (ACS) and in those undergoing percutaneous coronary intervention (PCI). However, an interindividual variability in platelet inhibition response to clopidogrel has been demonstrated, and is associated with recurrent(More)
We have shown that human high molecular weight kininogen is proangiogenic due to release of bradykinin. We now determined the ability of a murine monoclonal antibody to the light chain of high molecular weight kininogen, C11C1, to inhibit tumor growth compared to isotype-matched murine IgG. Monoclonal antibody C11C1 efficiently blocks binding of high(More)
Inflammation is accompanied by activation of the plasma kallikrein-kinin system (KKS). KKS activation has been demonstrated in a variety of inflammatory human diseases. To further explore the participation of KKS in arthritis and inflammatory bowel disease, we used two experimental animal models in arthritis and enterocolitis. We found that activation of(More)
