    Sammanfattning : Currently, the transplantation of islets of Langerhans is a viable means to maintain control of blood sugar levels and reduce the risk of hypoglycemia in defined populations with brittle type I diabetes mellitus or those requiring pancreatectomy. However, the process of islet isolation is highly variable and not all isolations result in islet numbers or quality suitable for transplantation. LÄS MER

  3. 2. Technical challenges in human islet isolation

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Transplantation of islets of Langerhans is an effective treatment option for patients with brittle type 1 diabetes mellitus. This treatment restores glucose control and also reduces hypoglycemia. Unfortunately, the outcome from islet isolations is variable, and many preparations do not yield sufficient islet number or islet quality. LÄS MER

    Sammanfattning : General attrition rates in drug development pipeline have been recognized as a necessity to shift gears towards new methodologies that allow earlier and correct decisions, and the optimal use of all information accrued throughout the process. The quantitative science of pharmacometrics using pharmacokinetic-pharmacodynamic models was identified as one of the strategies core to this renaissance. LÄS MER
