Endobronchial removal of uncovered stent using argon plasma coagulation via fibreoptic bronchoscopy.

Bronchial stenosis is a complication of lung transplantation that often requires repeated balloon dilation, endobronchial treatments, and possibly stent placement. Endobronchial stents, particularly uncovered ones, may have several complications including excessive granulation tissue that cause airways obstruction and impaired mucociliary clearance, which may lead to inflammation and infections. Removal of epithelized endobronchial stents is usually done in the operating room using rigid bronchoscopy.

Genetic and morphological evidence for substantial hidden biodiversity in a freshwater crayfish species complex.

North America is a center of biodiversity for freshwater crayfish, with >300 described species, mostly in the family Cambaridae. However, the phylogenetic and phylogeographic relationships among these taxa are poorly understood, despite their ubiquitous occurrence in North American freshwater habitats. Here, we target the geographically widespread Orconectesvirilis and its sister taxa for genetic and morphological investigation.
