development of inhibitor to factor viii is the most serious complication of hemophilia therapy. to determine the prevalence of inhibitors in iran hemophilia a patients exposed to blood products, 1280 hemophilia a patients (age range 9 months-84 years) were evaluated. all patients received several blood products such as fresh frozen plasma (ffp), cryoprecipitate, and factor viii. 635 of 1280 pat...

This study was designed to detect vascular endothelial growth factor (VEGF) and its soluble receptor (sVEGFR-1) in follicular fluid specimens and to evaluate the importance of sVEGFR-1 with respect to ovarian response to gonadotrophin stimulation. A total of 69 patients was treated for IVF with recombinant human follicle stimulating hormone (FSH). Concentrations of VEGF and sVEGFR-1 were quanti...

A recently established, one-dimensional isoelectric focusing (IEF) method for distinguishing major histocompatibility complex (MHC) class II polymorphisms in an outbred species, cattle, has allowed us to analyse the involvement of the MHC in the recognition of antigen by bovine T cells. Bovine T-cell lines of Th cell phenotype (BoCD4+) specific for ovalbumin were generated from six individual h...

Granulocyte colony-stimulating factor (G-CSF) can effectively mobilize hematopoietic stem and progenitor cells from bone marrow into blood, thereby allowing peripheral blood stem cells (PBSCs) to be used for transplantation. The efficiency of PBSC mobilization response to G-CSF is a multigene trait. DBA/2 (high-responder) and C57BL/6 (low-responder) mice were used for a genetic analysis of G-CS...

It has previously been demonstrated that gingival fibroblasts derived from nifedipine-reactive patients (nifedipine responders) show a greater cell proliferation rate than those from nifedipine non-reactive patients (nifedipine non-responders) in the presence of 1 microM nifedipine. The aim of the present study was to characterize cell cycle differences between nifedipine responder and non-resp...

The H-2 haplotype of the chimeric host determines the responder phenotype of maturing T cells. Spleen cells of chimeric mice formed when (K(k) nonresponder to D(b) x K(b) responder to D(b) plus vaccinia)F(1) bone marrow cells were used to reconstitute K(b)D(b) (C57BL/6 D(b) responder) irradiated recipients generated high levels of D(b) plus vaccinia virus-specific cytotoxic T cells. The same st...

BACKGROUND The risk for donors of allogeneic hematopoietic stem cells transplants is generally considered negligible. Scattered reports of severe complications and a recent controversy on hematopoietic malignancies after granulocyte colony-stimulating factor administration have challenged this opinion. DESIGN AND METHODS Three hundred and thirty-eight allogeneic transplant teams from 35 prima...
