BACKGROUND After heart transplantation, 1-year and 5-year survival rates are 79% and 63%, respectively, with rejection, infection, and allograft coronary artery disease accounting for the majority of deaths. Mycophenolate mofetil (MMF), an inhibitor of the de novo pathway for purine biosynthesis, decreases rejection in animals and in human renal(More)
Adiponectin is a hormone that lowers glucose production by increasing liver insulin sensitivity. Insulin blocks the generation of biochemical intermediates for glucose production by inhibiting autophagy. However, autophagy is stimulated by an essential mediator of adiponectin action, AMPK. This deadlock led to our hypothesis that adiponectin inhibits(More)
In low flow states, underestimation errors occur when the Gorlin formula is used to calculate valve area. A model of valvular stenosis designed to examine changes in the hydraulic discharge coefficient (Cd) and coefficient of orifice contraction (Cc) may explain these errors. Unsteady flow was examined in a pulsatile pump model and in a dog model. Valve(More)
BACKGROUND Bone morphogenetic proteins (BMP) induce ectopic bone formation in vivo and may play a role in normal bone development. In addition, bone morphogenetic activity, as measured in a bone-forming assay in immunodeficient, athymic nu/nu mice, is present in a proportion of osteosarcomas; this activity, which may be mediated by BMP, is correlated with a(More)
BACKGROUND Pegylated liposomal doxorubicin (PL-DOX) has been shown in preclinical models to induce less cardiotoxicity than non-liposomal doxorubicin. Endomyocardial biopsy is a highly sensitive and specific method for detecting anthracycline-induced cardiac damage. PATIENTS AND METHODS Myocardial tissue from ten KS patients who had received cumulative(More)
BACKGROUND Bone morphogenetic proteins (BMPs) are potent inducers of bone formation. Functional and immunohistochemical studies have identified BMPs in a subset of osteosarcomas. In the present study, the authors extend the analysis of BMP expression to other bone and soft tissue sarcomas. METHODS Monoclonal antibody AbH3b2/17 against human BMP-2 and(More)
Leukaemia inhibitory factor (LIF) is a cytokine which possesses a wide range of biological activities including, like IL-6, the capacity to stimulate acute phase protein (APP) synthesis. We have developed a sensitive and specific ELISA for human LIF, and tested the circulating cytokine levels in various disease states, some of which are associated with(More)
We postulated that transplant coronary artery disease with rapid progression to more than 50% stenosis within a 1-year interval may have a different prognosis from transplant coronary artery disease with a more indolent rate of progression. Annual coronary angiograms of 139 consecutive patients who underwent transplantation between January 1968 and February(More)
'Autoantigen complementarity' is a theory proposing that the initiator of an autoimmune response is not necessarily the autoantigen or its molecular mimic, but may instead be a peptide that is 'antisense/complementary' to the autoantigen. We investigated whether such complementary proteins play a role in the immunopathogenesis of autoimmune(More)
Cardiac transplantation now permits prolonged survival for some patients with otherwise fatal heart disease. This report summarizes the hemodynamic and clinical characteristics of 25 patients who have survived five or more years after cardiac replacement. The average age of the patients at the time of operation was 40 +/- 10 (SD) years; 23 were men. The(More)
