We offer our heartfelt condolences to his esteemed family, the world nephrology community and Iranian nephrologist colleagues on the death of Professor Barry Brenner, who spent his fruitful life advancing the knowledge of nephrology.  
During his trip to Iran, Professor Brenner was very impressed with the advancement of nephrology knowledge in Iran.  His passing is considered a loss for the nephrology community throughout the world. 
We hope that we can advance the knowledge of nephrology so that we can bring peace and happiness to the mind of this great teacher.
