In the recent years, laser ablation in liquid has become an increasingly important technique for the fabrication of NPs. this paper reports our recent studies on the generation of ZnO NPs by ablation of metal targets in aqueous environments using Q-switch Nd-YAG laser (λ=532nm) immersed in NaOH (0.1M). The Surface topography studied by atomic force microscopy revealed wider size distributio...

Uterine fibroids are benign solid tumors that are present in the majority of women. While often asymptomatic, fibroids can result in abnormal uterine bleeding, pelvic pressure, pain, subfertility, dyspareunia and other symptoms. Submucous and intramural fibroids are most associated with heavy menstrual bleeding; subserosal fibroids are more often innocuous unless sufficiently large so as to con...

purpose: to investigate the effects of surface ablation excimer surgery on higher-order aberrations and to assess the safety and efficacy of wavefront-guided surface ablation excimer surgery in patients with hyperopia and hyperopic astigmatism. methods: in this analytical & descriptive study, wavefront-guided surface ablation excimer surgery was performed in 58 eyes of 31 patients with hyperopi...

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 who...

In order to compare the clinical efficacy, safety, success rate and probable complications of rollerball ablation with cutting loop endometrial resection in the treatment of menorrhagia, eighty-three women in reproductive age suffering from menorrhagia who did not respond to medication were treated in a randomized study comparing cutting loop endometrial resection with hysteroscopic rollerb...

background: about half of all patients who undergo mitral valve surgery suffer from atrial fibrillation (af). cox described the surgical cut-and-sew maze procedure, which is an effective surgical method but has some complications. this study was designed to evaluate the efficacy of a substitution method of radiofrequency ablation (rfa) for patients undergoing mitral valve surgery with af. metho...

background: noninvasive techniques for the localization of the accessory pathways (aps) might help guide mapping procedures and ablation techniques. we sought to examine the diagnostic accuracy of strain imaging for the localization of the aps in wolff-parkinson-white syndrome. methods: w e prospectively studied 25 patients (mean age = 32 ± 17 years, 58.3% men) with evidence of pre-excitation o...

introduction: one of the minimally invasive methods of treatmenting liver malignancies is radiofrequency ablation (rfa) which can be applied to primary or secondary tumors. nevertheless, the disease recurrence is probable after rfa application partially due to the inadequate capability of temperature monitoring of the target tissue and visualizing the thermal damage. the goal of this work was t...

patients and methods this was a retrospective study including 207 consecutive patients who were enrolled using computerized hepatocellular carcinoma database consisting of 105 patients who underwent combined tace with rfa, and 102 patients who underwent tace alone with long-term follow-up. results the complete remission rate was meaningfully higher in the combination group (97.1%, 102/105) than...
