Cardiothoracic Surgery Research
Congratulations to Scott B. Johnson, MD, Professor, and Head of Division of Thoracic Surgery, who has been awarded $50,000 by the IIMS/CTSA Pilot Project grant for proposal entitled “Efficacy of Inhaled Nanoparticle Tacrolimus in Preventing Rejection in a Rodent Lung Transplant Model.” This proposal is one of 16 to be funded (some in partnership with CTRC and SOM), ranking near the top of the 74 submissions.
In addition, Dr. Johnson has been awarded $9,900 for academic year 2011-2012 by the Institute for Integration of Medicine and Science in support of his Translational Technology Resources (TTR) application entitled, “Evaluation of Inhaled Nanoparticle Tacrolimus in Attenuation of Ischemia Reperfusion Injury in a Rat Lung Transplant model.”

Biosketch: Nitin A Das is a medical graduate from Christian Medical College, Ludhiana, India and completed one-year rotatory internship as part of this education. Thereafter, he served as a Medical Officer at a rural Mission Hospital for two years, where he was involved in direct patient care of all ages and walks of life, at both in-patient and out-patient, and performed several major and minor surgical procedures. He pursued a post-graduate training in General Surgery at St Stephen's Hospital, Delhi, India as a Diplomate of National Board for over two years. After coming to United States in 2002, Nitin cleared his USMLE Boards and was ECFMG certified and was accepted into the General Surgery Residency program at St Louis University Hospital, St Louis, MO. He did two years of Preliminary residency and then joined Washington University as a Post-doctoral Research Fellow. He was with the Cardiothoracic Surgery Division at WUSM for two years and performed several rat lung transplants. During this time he also taught the procedure to visiting micro-surgeons and new researchers in the lab. He also participated in research using emphysematous human lungs and collaborated with other disciplines viz. Radiology. He cherishes his involvement with the human lung transplant program and the opportunity to go on harvest of the donor specimens. After two years in lung transplant research, Nitin made a lateral move to the Division of Urology Research Lab where he studied the urodynamic changes in a porcine ureter in presence of ureteric stone. He also studied the benefit of selective arterial clamping during partial nephrectomy to minimize post-op renal impairment. He presented the research done at International and National meetings.
He has joined the Department of Cardiothoracic Surgery Research Lab as a Research Coordinator since June 2010 and intends to play an active role in the on-going research endeavors especially those related to lung transplantation. He will be collaborating with other PIs as well in their new and on-going projects not related to lung transplantation including clinical research.
