A 2008 survey of American Association of Hip and Knee Surgeons membership explored current venous thromboembolism (VTE) protocols for lower-extremity total joint surgery. Fifty-three percent reported a change in VTE-related practices in the last 5 years. More than 70% reported that their primary hospital now mandates VTE prophylaxis. Although 74% of their(More)
To improve the efficacy of immunotherapy for cancer and autoimmune diseases, recent ongoing and completed clinical trials have focused on specific targets to redirect the immune network toward eradicating a variety of tumors and ameliorating the self-destructive process. In a previous review, both systemic immunomodulators and monoclonal antibodies (mAbs),(More)
Familial and twin studies in Caucasians have established that the MHC class II allele HLA-DRB1*0301 (DR3) is a strong susceptibility gene in Graves' hyperthyroid disease (GD). To determine if a DR3 transgene could help establish an animal model for GD, we expressed DR3 molecules in class II-knockout NOD mice (H2Ag7-). DR3+g7- mice were given cardiotoxin(More)
Certain blood group antigens may play a role in the removal of senescent red cells from the circulation. In order to elucidate this hypothesis, we have investigated the effect of red cell aging on Rh blood group antigens. Red cells from volunteer donors were separated into subpopulations of uniformly defined densities on discontinuous Stractan density(More)
Experimental autoimmune thyroiditis (EAT) can be induced in genetically susceptible mice by immunization with the self antigen, thyroglobulin (Tg). Since susceptibility is linked to H2 class II molecules, we have generated human leukocyte antigen (HLA) class II transgenic mice to study potential HLA associations with Hashimoto's thyroiditis. DR3(More)
Murine experimental autoimmune thyroiditis (EAT) is a model for Hashimoto's thyroiditis that has served as a prototype of T cell-mediated autoimmunity for more than three decades. Key roles for MHC restriction and autoantigen influence on susceptibility to autoimmunity have been demonstrated in EAT. Moreover, it has served a unique role in investigations of(More)
BACKGROUND Colorectal cancer (CRC) is increasing in young patients. We aimed to assess the trends of CRC and its corresponding clinical presentation in the young. METHODS Cancer registry patients were divided into 3 groups according to age:<50, 50-75, and >75 years. Charts were reviewed for average-risk patients <50 years of age to assess(More)
We have examined the induction of autoimmunity and the maintenance of sustained hyperthyroidism in autoimmunity-prone human leucocyte antigen (HLA) DR3 transgenic non-obese diabetic (NOD) mice following chronic stimulation of the thyrotropin receptor (TSHR) by monoclonal thyroid-stimulating autoantibodies (TSAbs). Animals received weekly injections over the(More)
When CD4+ CD25+ regulatory T cells are depleted or inactivated for the purpose of enhancing antitumor immunity, the risk of autoimmune disease may be significantly elevated because these regulatory T cells control both antitumor immunity and autoimmunity. To evaluate the relative benefit and risk of modulating CD4+ CD25+ regulatory T cells, we established a(More)
Both genetic and environmental factors contribute to autoimmune disease development. Previously, we evaluated genetic factors in a humanized mouse model of Hashimoto's thyroiditis (HT) by immunizing human leucocyte antigen DR3 (HLA-DR3) and HLA-DQ8 transgenic class II-knock-out non-obese diabetic (NOD) mice. DR3+ mice were susceptible to experimental(More)
