Selenium nanoparticles (SeNPs) have been demonstrated potential for use in diseases associated with oxidative stress. Functionalized SeNPs lower toxicity and higher biocompatibility could bring better therapeutic activity clinical application value. Herein, this work was conducted to investigate the protective effect of Pleurotus tuber-regium polysaccharide-protein complex funtionnalized...

BACKGROUND Interspecific hybridization is widespread, occurring in a taxonomically diverse array of species. The Cyprinidae family, which displays more than 30% hybridization, is a good candidate for studies of processes underlying isolation and speciation, such as genetic exchange between previously isolated lineages. This is particularly relevant in the case of recent hybridization between an...
