Dr. Colburn studies several important areas in medicine, including the effectiveness of treatments for idiopathic clubfoot, a condition in newborns where the foot is misaligned. His work with the Ponseti method has shown that most babies can be corrected without surgery. Additionally, he examines how proteins and immunosuppressive drugs affect kidney transplant success, particularly in conditions like chronic allograft nephropathy. Another key area of his research involves muscle recovery after blood flow issues, seeking to find better treatment options for patients recovering from traumas or surgeries.
Key findings
In a study of 57 clubfeet treated with the Ponseti method, 54 were successfully corrected without surgery, highlighting the method's effectiveness in infants.
The protein selenium-binding protein-1 was almost absent in kidney transplants affected by chronic allograft nephropathy, indicating its potential role in improving graft survival.
After muscle ischemia in rabbits, the best recovery of muscle function observed was 61% in controlled reperfusion, with some methods resulting in complications where blood flow could not effectively return.
Rapamycin antagonizes the effects of cyclosporin A and tacrolimus on T cell activation, providing crucial insights into how these drugs can be optimized for organ transplant patients.

Plain English This study explored new ways to combine two complex techniques—block copolymer self-assembly and optical lithography—using a special type of material called photoresist. The researchers found that by using these materials, they could create tiny, precise structures that are smaller than typical patterns made with standard lithography. This advance is significant because it allows for improved manufacturing of materials that could enhance various technologies.

Plain English Researchers studied a protein called selenium-binding protein-1 (SBP-1) in smooth muscle cells within kidneys of rhesus monkeys that had chronic allograft nephropathy (CAN), a condition that can occur after kidney transplantation. They found that SBP-1 was nearly absent in the kidney transplants affected by CAN, while another protein, SMC alpha-actin, was still present, suggesting that the loss of SBP-1 is significant in the disease process. Understanding this relationship is important because it could lead to better treatments for preserving kidney transplants.

Rapamycin antagonizes cyclosporin A- and tacrolimus (FK506)-mediated augmentation of linker for activation of T cell expression in T cells.

International immunology
Cho CS, Chang Z, Elkahwaji J, Scheunemann TL, Manthei ER +3 more
Plain English This study examined how three immunosuppressive drugs—rapamycin, cyclosporin A (CsA), and tacrolimus (FK506)—affect a signaling molecule called LAT, which is important for T cell activation. The researchers found that while CsA and FK506 increase LAT expression, rapamycin actually inhibits it, meaning it works against the effects of the other two drugs. This matters because it helps explain why these drugs have different effects on the immune system, which can lead to better designs for new treatments with fewer side effects.

Evaluation of the treatment of idiopathic clubfoot by using the Ponseti method.
2003
The Journal of foot and ankle surgery : official publication of the American College of Foot and Ankle Surgeons
Colburn M, Williams M
Plain English This study looked at how effective the Ponseti method is for treating babies with clubfoot, a condition where the foot is turned inward and downward. Out of 57 clubfeet treated with this method, 54 were corrected successfully without needing surgery, and only 2 patients required surgery afterward. This is significant because it shows that most babies with clubfoot can be treated effectively without surgery, reducing the risk of complications.
Who this helps: This helps infants with clubfoot and their families.
Skeletal muscle function after ischemia: "no reflow" versus reperfusion injury.
1991
The Journal of surgical research
Quiñones-Baldrich WJ, Chervu A, Hernandez JJ, Colburn M, Moore WS
Plain English This study investigated how well rabbit leg muscles recover after a period of restricted blood flow, or ischemia, when different methods of restoring blood flow are used. After five hours without blood, the muscle function was tested and found to be only slightly better in some methods compared to others, with the best recovery seen in controlled reperfusion and leukopenic/thrombocytopenic controlled reperfusion, both showing 61% function of normal muscle. Importantly, one method involving a drug (urokinase) completely prevented a serious issue called "no reflow," which prevents blood from returning to the muscle tissue, whereas this problem affected 40% to 67% of the muscles in the other methods.
Who this helps: This research helps doctors treat muscle injuries caused by blood flow issues in patients, especially those undergoing surgeries or trauma care.
