Hemorrhage due to trauma is the leading cause of preventable death among American soldiers, according the National Institute of Trauma. Uncontrollable bleeding is also seen regularly in civilian incidences of trauma and is a common major surgical complication. The human blood clotting process involves a complex cascade of tightly regulated enzymatic reactions. Two of the most important proteins in this cascade are fibrinogen and thrombin. Thrombin is an enzyme that activates fibrinogen monomers to form a polymeric fibrin network, forming the basis of a blood clot. During trauma, a state of consumptive coagulopathy, the body depletes these two proteins causing ...

T-Cell Manufacture For Treatment Of Acute Lymphoblastic Leukemia, Amit Pujari, Chi-Wei Man, Jinsang Park

Senior Design Reports (CBE)

Adoptive T-cell therapy is a recent medical development that has shown clinical success in treating relapsed acute lymphoblastic leukemia (ALL), a common form of cancer with a poor prognosis. Ironically, the treatment’s greatest advantage is at the same time deterring large pharmaceutical companies from commercializing it. Adoptive T-cell therapy is successful in treating ALL largely because it takes a patient’s own cells and engineers them to fight the cancer. While the autologous nature of the treatment helps to incorporate the engineered T-cells into the patient’s body, it also makes each treatment patient-specific. This does not fit into ...
