Essential hypertension (HTA) is the clinical expression of a disordered interaction between the genetic, physiological, and biochemical systems that under usual conditions maintain cardiovascular homeostasis. We studied the effects of the angiotensinogen M235T, angiotensin converting enzyme insertion/deletion (ACE I/D), and angiotensin II receptor 1 (AT1R)(More)
Numerous studies have reported beneficial effects of antioxidant drugs on semen quality, but there is no well-defined therapeutical protocol in male infertility. This study aimed to test the effects of vitamin E and selenium supplementation on lipid peroxidation and on sperm parameters. The study included 54 voluntary and infertile men who produced semen(More)
BACKGROUND Percutaneous balloon mitral commissurotomy (BMC) has been proposed as an alternative to surgical closed mitral commissurotomy (CMC) and open mitral commissurotomy (OMC) for the management of rheumatic mitral valve stenosis (MS). METHODS AND RESULTS We conducted a prospective, randomized trial comparing the results of the 3 procedures in 90(More)
INTRODUCTION Excess of total homocysteine (tHcy) and decrease of thiolactonase activities (HTase) have been proposed as risk factors for coronary artery diseases (CAD). OBJECTIVES We evaluated the relationship of tHcy and HTase with paraoxonase 1 (PON1) gene polymorphism according to CAD severity. DESIGN AND METHODS 118 healthy volunteers and 91 CAD(More)
The aim of this study was to evaluate plasma lipoprotein(a) [Lp(a)] concentrations in Tunisian patients with type 2 diabetes mellitus (DM), to correlate the values with other lipid parameters, and to examine the relationship to glycemic control and coronary heart disease (CHD). Diabetic patients with and without CHD (n=200) had significantly higher levels(More)
BACKGROUND/AIMS The role of methylenetetrahydrofolate reductase (MTHFR) and angiotensin-converting enzyme (ACE) gene polymorphisms as being risk factors for diabetes is still controversial. The aim was to investigate the distribution of ACE and MTHFR genotypes as well as to evaluate the role of plasmatic total homocysteine levels (tHcy) and ACE activity in(More)
To evaluate the predictors of early mortality in patients on chronic hemodialysis, we reviewed the records of 192 patients starting chronic hemodialysis at our centre between January 1996 and September 1999. The overall incident mortality within 90 days was 32 (16.7%) patients. The cardiovascular causes accounted for 50% of all the causes of mortality. By(More)
Suitable stabilization conditions obtained for continuous chaotic systems are generalized, in this paper, to discrete-time chaotic systems. The proposed approach , leading to these conditions for complete synchronization, anti-synchronization and hybrid synchronization phenomena studies, is based on the use of state feedback and aggregation techniques for(More)

Based on aggregation techniques associated with the arrow form matrix, to derive the stability property of dynamic discrete-time complex systems, a new strategy of control is formulated for chaos hybrid synchronization of two identical 3D Henon maps. The designed state feedback controller ensures that the state variables of both controlled hyperchaotic(More)
UNLABELLED BACKGROUND The development of Primary Biliary Cirrhosis (PBC) during the course of Systemic Lupus Erythematosus (SLE) is extremely rare. We report the case of a geriatric woman who was diagnosed with SLE at 69 years of age then with primary biliary cirrhosis one year later. CASE PRESENTATION A 70-years-old woman, who had been diagnosed with(More)
