Production of pili, hemolysin and siderophores in the urinary isolates of Escherichia coli [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo, 2013
Introduction. Escherichia coli (E. coli) are the most frequent cause of the urinary tract infections. Uropathogenic E. coli (UPEC) produce virulence factors which enable them to survive in the urinary tract and cause an infection. Objective.

Tumor Microenvironment‐responsive Nanocatalyst for Targeted Chemodynamic Cancer Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
An Tumor microenvironment‐responsive nanocatalyst system composed of PLGA‐encapsulated Ca–Fe peroxide and polyarginine enables sustainable Fenton reaction in tumors. Low levels of H2O2 (50–100 µm) initiate the nanoparticle degradation, while polyarginine‐derived nitric oxide accelerates Fe3+ reduction, leading to self‐amplifying •OH generation for ...
