Platelet aggregation and TGF-beta(1) plasma levels in pregnant women with preeclampsia
(Elsevier B.V., 2008-10-01)
Objectives: Platelets and transforming growth factor-beta(1) (TGF-beta(1)) are thought to be involved in the pathogenesis of preeclampsia. Our objectives were to determine plasma concentration of TGF-beta(1) in normotensive ...
Platelet activation in experimental arterial thrombosis.
(1987-12-01)
Platelet aggregates were studied in dogs with induced arterial thrombosis, by the method of Wu and Hoak. Blood was withdrawn from a jugular vein and from the femoral vein on the operated side 24 h after thrombus induction ...
Evaluation of platelet number and function and fibrinogen level in patients bitten by snakes of the Bothrops genus.
(1995-01-01)
Platelet function and plasma fibrinogen levels were evaluated in 14 patients, 10 males and 4 females, aged 13-59 years bitten by Bothrops genus snakes. There was a statistical difference (p < 0.05) among plasma fibrinogen ...
Platelet hyperaggregability in high-fat fed rats: A role for intraplatelet reactive-oxygen species production
(Biomed Central Ltd., 2012-01-16)
c Background: Adiposity greatly increases the risk of atherothrombotic events, a pathological condition where a chronic state of oxidative stress is reported to play a major role. This study aimed to investigate the ...
Platelet aggregation and antibacterial effects of an L-amino acid oxidase purified from Bothrops alternatus snake venom
(Elsevier B.V., 2004-06-01)
The isolation and biochemical/enzymatic characterization of an L-amino acid oxidase, Balt-LAAO-I, from Bothrops alternates snake venom, is described. Balt-LAAO-I is an acidic glycoprotein, pI similar to 5.37, homodimeric, ...
Characterization of a new platelet aggregating factor from crotoxin Crotalus durissus cascavella venom
(Springer, 2006-04-01)
In this article we investigated the platelet aggregating activity of whole crotoxin and its subunits isolated from Crotalus durissus cascavella venom. During the purification protocols of the venom, using HPLC molecular ...
Effects of simvastatin/ezetimibe on microparticles, endothelial progenitor cells and platelet aggregation in subjects with coronary heart disease under antiplatelet therapy
(Associação Brasileira de Divulgação Científica, 2014-05-02)
It is not known whether the addition of ezetimibe to statins adds cardiovascular protection beyond the expected changes in lipid levels. Subjects with coronary heart disease were treated with four consecutive 1-week courses ...
