Radiofrequency catheter ablation procedures are considered a reasonable option for patients with symptomatic, drug refractory atrial fibrillation (AF). Ablation procedures have been reported to effectively restore sinus rhythm and provide long-term relief of symptoms. Both electrical and structural remodeling occurs with AF. A reversal of the electrical remodeling develops within 1 week after r...

Visual deprivation leads to massive reorganization in both the structure and function of the occipital cortex, raising crucial challenges for sight restoration. We tracked the behavioral, structural, and neurofunctional changes occurring in an early and severely visually impaired patient before and 1.5 and 7 mo after sight restoration with magnetic resonance imaging. Robust presurgical auditory...

Despite huge investments over the last quarter century in the US, it is widely recognized that the ubiquitous practice of stream restoration has produced few documented cases of long-term ecological benefits, especially at the watershed scale. This dubious track record results from several factors including inadequate monitoring and feedback, an emphasis on small-scale static projects that are ...
