A new method for identifying rigid link models of lower limbs.

A new method for identifying rigid link models of human lower limbs has been proposed in this paper. The method was motivated by necessity of simulating human body movements for rehabilitation or for design of assistive devices. The method is based on combination of random search and least squares estimation techniques.

Clinical outcome and accommodation in ABO incompatible kidney transplantation.

We performed 84 ABO-incompatible kidney transplants at Toho University since 1989, with plasmapheresis and exchange replacing AB blood group plasma as pre-conditioning to reduce anti-donor blood group antibodies. Our current immunosuppression protocol consists of basiliximab, MMF, steroid, and cyclosporine or tacrolimus, including splenectomy. Overall patient/ graft survival rates (n=84) were 95/93 at one year, 94/92 at 3 years, 87/80 at 5 years, 87/75 at 7 years, and 83/67 at 10 years.

ABO incompatible kidney transplantation --immunological aspect-.

ABO incompatible kidney transplantation (ABOINCKT) has been developed in Japan because of the shortage of cadaveric donors. We have performed 76 living-donor ABOINCKT in our center. Donor blood type antibody was removed by immunoadsorption or plasmapheresis and exchange.

Reversibility from delayed hyperacute rejection in ABO-incompatible renal transplantation: histopathological findings of renal allograft biopsy.

ABO-incompatible renal transplantation (ABOIRTx) tend to lead to blood type antibody-mediated rejection, the so-called delayed hyperacute rejection (DHAR), which results in short-term graft loss. To clarify the accurate incidence and prognostic value of DHAR among ABOIRTx, we reviewed biopsy specimens obtained from ABOKTx allografts with abrupt dysfunction during the early period after transplantation. Among 74 ABOIRTx patients, 34 patients displayed allograft dysfunction within 14 days following transplantation.
