Summary
This study aims to define in both animal models and children how the testis descends from the abdomen to scrotum, and how undescended testis and inguinal hernia are likely to be caused by defects in the same, very indirect signalling pathway. The results will demonstrate where to look for genetic causes and proof of principle for possible future medical treatments for the 3 commonest major operations in children for congenital and acquired undescended testis and inguinal hernia.
Nitric Oxide On Cardio Pulmonary Bypass In Congenital Heart Disease

Summary
Children undergoing open heart surgery on a heart lung machine can experience serious side effects from the exposure to the artificial circulation during surgery and may have either prolonged need for life support in intensive care or even may suffer from long term complications. In this study we investigate the use of a new approach using nitric oxide, a anti-inflammatory gas, during surgery to reduce these side effects.
Novel Cell Therapy For Hirschsprung Disease: From Patient IPS Cells To Large Animal Trials

Funding Amount

Summary
In Hirschsprung disease the lower bowel has no nerve cells. It does not function so it is surgically removed but quality of life is poor. A new idea is to replace the missing cells with new ones. Human infants are very large so we will use new stem cell technologies to create large numbers of cells. We will use polymer chemistry to devise a method of getting the cells into such a large organ as the bowel, and trial these on a model, the piglet, which closely resembles in size the human baby.
