Metal-contaminated environments may produce soluble metal(loid) particles whose stability and transportability are determined by environmental conditions and particle composition. The Coeur d'Alene River Basin of northern Idaho, USA, is impacted by legacy mine waste-estimated 56 million tonnes of waste rock containing 900,000 t of Pb and 700,000 t of Zn were discharged into the Coeur d'Alene River and its tributaries during mining of argentiferous galena-sphalerite deposits. These legacy disposal practices resulted in substantial metal contamination-including As, Cd, Fe, Pb, Mn, and Zn-of floodplain sediments. Monthly lakewater samples and sediment cores were collected along the shoreline of a metal-contaminated lateral lake of the Coeur d'Alene River. Porewater was extracted from upper and losummer transition that induces redox changes and increases particle stability. The presence of mining-related minerals and seasonal changes in environmental conditions allow for formation of dissolved metal particles, but the limited stability of the particles and/or low permeability of the sediments appear to limit, but not fully restrict, possible transport of metal particles to the overlying lakewater.Objective Patient-derived xenografts (PDX) are useful preclinical models to study cancer biology and mechanisms of drug response/resistance, particularly in molecularly targetable tumors. However, PDX engraftment may not be stochastic. We investigated clinical, histological and molecular features associated with PDX engraftment in a large cohort of EGFR-mutated lung adenocarcinoma (LUAD). Material and methods Samples were collected by different methods from patients at various disease stages and
