Isolation and Characterization of Meniscus Progenitor Cells From Rat, Rabbit, Goat, and Human.

Objective: Meniscus progenitor cells (MPCs) have been identified as promising candidates for meniscus regeneration, and it is crucial for us to understand meniscus injury repair mechanism at the cellular level. In this study, we investigate the biological properties of MPCs isolated from different species using the differential adhesion to fibronectin (DAF) technique. We aim to characterize MPCs in different species and evaluate the feasibility of these models for future meniscal investigation.

On-road measurements of pollutant concentration profiles inside Yangkou tunnel, Qingdao, China.

To obtain physical properties of pollutant concentrations encountered by vehicle commuters during travelling Yangkou tunnel (7.76 km) of Qingdao City, particle concentration measurements are accompanied by the measurements of gaseous species (CO and CO). The field campaigns are on-road conducted from April 26 to September 23, 2014.

Congestive heart failure after extensive catheter ablation for atrial fibrillation: prevalence, characterization, and outcome.

Introduction: This study sought to describe a new complication of catheter ablation for atrial fibrillation (AF): new onset congestive heart failure (CHF) after extensive ablation for AF.

Methods And Results: Data from 12 patients developing CHF after ablation were prospectively collected. All patients underwent extensive ablation for AF including circumferential pulmonary venous ablation and complex fractionated atrial electrograms guided ablation.

Efficacy, safety and outcome of catheter ablation for atrial fibrillation in octogenarians.

Background And Objectives: Catheter ablation is effective in treating patients with atrial fibrillation (AF). The aim of the study was to evaluate the safety, efficacy and outcome of catheter ablation for AF in octogenarians.

Methods And Results: 377 consecutive patients were divided into three groups based on age: ≥80 years (group 1; n=49), 70-79 years (group 2; n=151), 60-69 years (group 3; n=177).
