[Virtual simulation for learning cataract surgery].

Introduction: The training in phacoemulsification cataract surgery in our context requires a long learning curve for a novice surgeon starting from the observation period to the realization of the different operating stages being supervised by a senior surgeon, all under stressful conditions. Topical or locoregional anesthesia limits the communication in the operating room between the novice surgeon and his mentor; thus, increasing the risk of having more operative complications. To reduce the teaching time of cataract surgery, our department has introduced virtual simulator trainings for phacoemulsification.

Flocculation monitoring of wastewater by using impedance spectroscopy.

The aim of the present work is to monitor the flocculation process using the analysis of the electric and dielectric properties. Therefore the dielectric and electrical characteristics of wastewater with different cationic polymer concentrations were investigated via the impedance spectroscopy (IS) method. Impedance measurements were carried at different concentration of cationic polymer in the frequency range from 0.

IL-17A, IL-17RC polymorphisms and IL17 plasma levels in Tunisian patients with rheumatoid arthritis.

Background: Interleukin-17 (IL-17), a cytokine mainly secreted by Th17 cells, seems to play a significant role in the pathogenesis of rheumatoid arthritis (RA). Functional genetic polymorphisms in IL-17 and its receptor genes can influence either qualitatively or quantitatively their functions. Therefore, we aimed to study the impact of IL17-A and IL17RC polymorphisms on plasma level of IL-17 and RA susceptibility and severity.

Comparison of corneal thickness and biomechanical properties between North African and French patients.

Purpose: To determine whether corneal thickness and rigidity vary between French and North African refractive surgery candidates.

Setting: Three clinics in North Africa and 1 hospital in France.

Design: Cross-sectional study.
