Recent studies provide evidence on the emerging role of the SOCS1 gene in the development and progression of atherosclerotic lesions. This gene encodes for the suppressor of the cytokine signaling-1 protein that interacts directly with the Janus kinases that are essential intracellular mediators of the immune cytokine action. The aim of this study was to(More)
BACKGROUND Clopidogrel is a pro-drug and its intestinal absorption is limited by the P-glycoprotein encoded by the ABCB1 gene. It is metabolized hepatically by cytochrome P450 enzymes encoded by CYP genes to produce an active metabolite that antagonizes the P2Y12 platelet receptor. Some patients exhibit poor clopidogrel responsiveness due to polymorphisms,(More)
There is continued debate as to whether a combined reperfusion regimen with platelet glycoprotein IIb/IIIa inhibitors provides additional benefit in optimal myocardial reperfusion of patients with a ST-elevation acute myocardial infarction (AMI). In addition, the best angiographic method to evaluate optimal myocardial reperfusion is still controversial.(More)
Inflammation plays an essential role in the development and progression of atherosclerotic lesions. Cytokines of the interleukin-1 family are central regulators in immunoinflammatory mechanisms. In the present work, the role of interleukin 1 (IL-1) and IL-1 receptor antagonist (IL-1RN) gene polymorphisms as susceptibility markers for acute coronary syndrome(More)
A three-year prospective study was conducted to assess the efficacy and safety of transjugular liver biopsy with a Trucut-type needle employing an automated device. Fifty-two consecutive patients (39 women and 13 men), ages 46.3+/-14.6 years, in whom percutaneous liver biopsy was contraindicated were included in the study. An 18-gauge transjugular hepatic(More)
BACKGROUND inflammation plays an essential role in the development and progression of atherosclerotic lesions and plaque disruption. Cytokines are central regulators in immunoinflammatory mechanisms. The aim of the present study was to evaluate the role of INF-γ and IL-6 gene polymorphisms as susceptibility markers for acute coronary syndromes (ACS) in a(More)
BACKGROUND Inflammation plays an essential role in the development and progression of atherosclerotic lesions. The major histocompatibility complex class II trans-activator (MHC2TA) is considered an important molecule in the inflammatory process regulation. The aim of the present study was to evaluate the role of MHC2TA gene polymorphisms as susceptibility(More)
Rheumatic fever is the most common cause of acquired heart disease in children and young adults worldwide, mainly in developing countries, and is the reason that a large number of patients with mitral stenosis will require some modality of treatment during their life span. The early therapeutic approach for this condition was solely surgical, but since the(More)
BACKGROUND Pregnancy can cause life-threatening complications in women with mitral stenosis. Frequently, there is an urgent need to increase the mitral valve area mechanically. In selected cases, percutaneous mitral balloon valvotomy (PMBV) has emerged as a safe and effective alternative to surgical commissurotomy. HYPOTHESIS The study evaluates the(More)
