When invasions go unnoticed: Public perception of the freshwater jellyfish Craspedacusta sowerbii in Europe

People and Nature, EarlyView.
Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

Transcriptomic comparative study between canalicular adenoma and HMGA2::WIF1 canalicular‐like pleomorphic adenoma

The Journal of Pathology, EarlyView.
Abstract Canalicular adenoma (CA) is a benign salivary gland tumor predominantly affecting the upper lip and is characterized by monomorphic epithelial cells arranged in branching cords within a loose and vascularized stroma. Unlike pleomorphic adenoma (PA), CA lacks a chondroid matrix and exhibits specific histological features, such as high cuboidal ...
