A recent worldwide survey shows that radiofrequency (RF) catheter ablation of paroxysmal atrial fibrillation (AF) is associated with a success rate of 75% without antiarrhythmic drugs, with major complications still occurring in 4–5% of the patients. This drives a continuous quest for a more effective and safer ablation approach. Currently, the use of robotic navigation systems, alternative for...

Background Planarian stem cells, or neoblasts, drive the almost unlimited regeneration capacities of freshwater planarians. Neoblasts are traditionally described by their morphological features and by the fact that they are the only proliferative cell type in asexual planarians. Therefore, they can be specifically eliminated by irradiation. Irradiation, however, is likely to induce transcriptom...

Catheter ablation has become an accepted treatment approach for drug-refractory, symptomatic atrial fibrillation (AF). The technical aspects of the procedure have evolved, but to a remarkable degree, the objective of the procedure is nearly the same as when it was first introduced: the electrical isolation of the principal trigger sites of AF, the pulmonary veins (PVI). The procedure has an exc...

Control of the longitudinal profile of ablated structures during laser processing is a key technological requirement. We report here on the direct machining of trenches in silicon with circular profiles using femtosecond accelerating beams. We describe the ablation process based on an intensity threshold model, and show how the depth of the trenches can be predicted in the framework of a causti...

  Atrial fibrillation (AF) is associated with inflammatory and hypercoagulability state. Previous studies evaluated the safety and efficacy of dabigatran and warfarin in prevention of thrombothic complications. This study was intended to assess the influence of these drugs on hemostatic and inflammatory markers among patient underwent pulmonary vein ablation.   A total of 100 patients with AF w...

Classic anti reflux procedures on children with a history of posterior urethral valve does not usually yield good results and often ends up with ureteral obstruction and even permanent urinary diversion. From 1981 through 1988,21 boys with history of posterior urethral valve (PUV) underwent evaluation for vesicoureteral (VU) reflux 17 boys had VU reflux. Following valve ablation, reflux di...

Introduction: Different approaches have been developed to find the position of the internal auditory canal (IAC)in middle cranial fossa approach. A feasibility study was performed to investigate the combination of cone beam computed tomography (CBCT), optical coherence tomography (OCT), and laser ablation to assist a surgeon in a middle cranial fossa approach by outlining the internal auditory ...
