The midterm efficacy of hybrid ablation of atrial fibrillation (AF) reported in recent papers is about 70% in terms of sinus rhythm maintenance without antiarrhythmic drugs. Bearing in mind that the majority of patients enrolled are patients with persistent and long-standing persistent AF, the reported efficacies seem to be very good. Despite the high efficacies, safety remains a critical issue in hybrid, and especially thoracoscopic ablations. The frequency of complications during thoracoscopic ablations is more than 10% in the majority of reports...

Over the recent years, the advent of single-shot techniques, such as circular catheter and cryoballoon ablation, has ushered in a new era in the catheter ablation approach and rhythm control strategies of patients with atrial fibrillation (AF). These techniques make it easier to navigate the heart and have the potential to decrease the threshold for, expand the access to, and increase patient and physician acceptance of rhythm-control therapies, that may lead to reduction of the AF disease burden and its socioeconomic impact...

BACKGROUND: The net benefit from local ablative therapy for pulmonary oligometastases remains unknown. The outcomes of stereotactic ablative radiotherapy (SABR) for metastatic lung lesions (MLLs) were analyzed retrospectively and compared with those of SABR for primary lung lesions (PLLs). METHODS: Medical records of patients treated with lung SABR between 2011 and 2014 were retrospectively reviewed. Basic patient, lesion and treatment characteristics were compared using the Pearson chi-square test for categorical and Mann-Whitney U test for continuous variables...

BACKGROUND: Lung Cancer is a primary tumor with poor prognosis. For early stage lung cancer, treatment options include surgical resection and microwave techniques. Percutaneous ablative techniques emerged as best therapeutic options for nonsurgical patients. METHODS: The aim of this study was to retrospectively analyze the clinical effect of CT-guided microwave ablation (MWA) treatment for patients with lung cancer who were not eligible for surgical resection. MWA was used to treat the tumor lesion of 113 patients with lung cancer who were in our hospital from Jan, 2013 to Jun, 2015...

The degradation of nonfunctional mitochondrial proteins is of fundamental relevance for maintenance of cellular homeostasis. The heteromeric CLPXP protein complex in the mitochondrial matrix is part of this process. In the fungal aging model Podospora anserina, ablation of CLPXP leads to an increase in healthy lifespan. Here, we report that this counterintuitive increase depends on a functional autophagy machinery. In PaClpXP mutants, autophagy is involved in energy conservation and the compensation of impairments in respiration...

Aims: Distinguishing between ventricular arrhythmias originating from the left ventricular infero-septal papillary muscles (PM) and those from the left posterior fascicle (LPF) by surface electrocardiography (ECG) is very difficult. This study aimed to report the ECG characteristics and radiofrequency catheter ablation of PM and LPF ventricular arrhythmias. Methods and results: A total of 127 patients underwent catheter ablation of idiopathic ventricular arrhythmias originating from the LPF (n = 106; 85 males; 10-70 years) or PM (n = 21; 14 males; 4-68 years) were studied...

Marjolin's ulcer is the malignant transformation of chronic nonhealing ulcers that have developed in burn scars or in any other chronic wound. Development of this malignancy tends to be slow and insidious, but it becomes more aggressive when the Marjolin's ulcer breaks free of the scar. We reviewed 24 cases of patients who complained of chronic burn wounds suspected to be Marjolin's ulcers. Histologically, chronic ulcer and pseudoepitheliomatous hyperplasia were 21%, respectively, and malignancy, including squamous cell carcinoma and leiomyosarcoma, were 58%...

In the study of adult stem cells and regenerative mechanisms, planarian flatworms are a staple in vivo model system. This is due in large part to their abundant pluripotent stem cell population and ability to regenerate all cell and tissue types after injuries that would be catastrophic for most animals. Recently, planarians have gained popularity as a model for eye regeneration. Their ability to regenerate the entire eye (comprised of two tissue types: pigment cells and photoreceptors) allows for the dissection of the mechanisms regulating visual system regeneration...

Titanium dioxide (TiO2) is a wide bandgap semiconductor that is chemically stable, non-toxic, and economical compared to other semiconductors and has been implemented in a wide range of applications such as photocatalysis, photovoltaics, and memristors. In this work we studied the femtosecond laser ablation of titanium dioxide powders (P25) dispersed either in water or deposited onto a fluoride-doped tin oxide (FTO) substrate. The process was used as a route to induce the phase-transformation of TiO2 nanoparticles which was governed by laser parameters such as ablation time and power...

Controlling nucleus localization is crucial for a variety of cellular functions. In the Drosophila oocyte, nuclear asymmetric positioning is essential for the reorganization of the microtubule (MT) network that controls the polarized transport of axis determinants. A combination of quantitative three-dimensional live imaging and laser ablation-mediated force analysis reveal that nuclear positioning is ensured with an unexpected level of robustness. We show that the nucleus is pushed to the oocyte antero-dorsal cortex by MTs and that its migration can proceed through distinct tracks...

Photo-related nanomedicine is of particular interest as an emerging paradigm toward precise cancer therapy, as demonstrated by the recent developments of photothermal therapy (PTT), an emerging technique employing light converting agents to burn cancerous cells by over-dosed optical energy-converted heat. However, most of the laser irradiations needed for effective PTT significantly exceed the maximal permissible power density in human skin, which is likely to damage surrounding normal tissues. Herein, we report a strategy of intranuclear PTT of cancer enabled by nuclear-targeted delivery of gold nanorods of ~ 10...

REVIEW
Sergio Conti, Atul Verma
Atrial fibrillation is the most common cardiac arrhythmia and the number of patients is expected to continuously increase in the next years. Catheter ablation is an effective, safe, and well-established treatment for patient with symptomatic and drug-resistant paroxysmal atrial fibrillation (PAF). Over the last decade, there was an increasing body of evidence demonstrating superiority of catheter ablation over antiarrhythmic drugs (AADs) in maintaining sinus rhythm. However, randomized clinical trials have not been conclusive to consider catheter ablation as a first-line therapy for PAF...

AIM: For selected patients with brain metastases (BMs), the role of stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (SFRT) is well recognized. The recent introduction of flattening filter free (FFF) delivery during linac-based SRS or SFRT allows shorter beam-on-time, improving patients' comfort and facility workflow. Nevertheless, limited experiences evaluated the impact of FFF linac-based SRS and SFRT in BMs treatment. Aim of the current study was to analyze SRS/SFRT linac-based FFF delivery for BMs in terms of dosimetric and early clinical results...

BACKGROUND: Catheter ablation has become the first line therapy in patients with symptomatic, recurrent, drug-refractory atrial fibrillation. Circumferential pulmonary vein ablation is still the standard approach in these patients. However, the results are not very favorable (especially in patients with persistent atrial fibrillation). Therefore, more complex ablation strategies and the usefulness of (short-term) adjunctive antiarrhythmic drug therapy are a matter of discussion. The aim of this study was to analyze whether short-term amiodarone therapy after catheter ablation (3 months) has a positive effect on the success rates after circumferential pulmonary vein ablation in patients with persistent atrial fibrillation...
