Currently little is known about the mechanisms regulating the homing and the early engraftment of prenatally transplanted hematopoietic cells due to the lack of a relevant functional assay. In this study, we have defined a reproducible kinetic profile of the homing and the early engraftment events in a murine model of prenatal stem cell transplantation. Light density mononuclear cells (LDMCs) f...

OBJECTIVE Neurologic complications are known as important cause of morbidity and mortality in orthotopic heart transplantation. Our aim was to identify the frequency and outcome of neurologic complications after heart transplantation in a prospective observational study. METHOD From September 93 to September 99, as part of our routine heart transplantation protocol all patients with end-stage...

INTRODUCTION Infections caused by multiple drug-resistant pathogens represent an increasingly often encountered challenge in clinical practice. The problem particularly applies to patients with chronic lung diseases resulting in multiple hospitalisations. The aim of this paper was to analyse the incidence of alert pathogens isolated from patients hospitalised in the department of lung diseases,...

BACKGROUND A growing body of evidence demonstrated an immune etiology as well as nonimmune mechanisms for episodes of clinical acute rejection and long-term allograft dysfunction. OBJECTIVE To investigate the correlation of IFN-γ-producing cells and TGF-β with incidence of clinical acute rejection in living-related and unrelated kidney allogarft recipients during the first post-transplant yea...

BACKGROUND Augmentation cystoplasty before or after renal transplantation is an option for patients with end-stage renal disease who are candidates for renal transplantation and have low capacity and poorly compliant bladders. OBJECTIVE To compare two surgical methods of bladder augmentation-enterocystoplasty (EC) and ureterocystoplasty (UC)-before kidney transplantation, and their outcome wi...

Adult hematopoietic stem cells (HSCs) are routinely used to reconstitute hematopoiesis after myeloablation; however, transplantation efficacy and multilineage reconstitution can be limited by inadequate HSC number, or poor homing, engraftment, or self-renewal. Here we report that mouse and human HSCs express prostaglandin E2 (PGE2) receptors, and that short-term ex vivo exposure of HSCs to PGE2...

Blood cells transplantation is largely replacing bone marrow transplantation because engraftment is more rapid. This accelerated engraftment is thought to be mediated by relatively mature committed hematopoietic progenitor cells. Herein, we have used a modified rhodamine (Rho) staining procedure to identify and purify Rho+/++ (dull/bright) and Rho- (negative) subpopulations of hematopoietic pro...

Acute liver failure (ALF) due to hepatitis A virus (HAV) infection is an uncommon but potentially lethal illness. The aim of this study was to identify readily available laboratory and clinical features associated with a poor prognosis among ALF patients with HAV infection. The presenting features of 29 adults with anti-HAV IgM positive ALF enrolled in the ALFSG_between 1998 and 2005 were revie...

Background: It is suggested that HA-1 mismatching among hematopoietic stem cell transplanted recipients-donors is associated with acute graft-versus-host disease (aGVHD). So the aim of this study was to evaluate HA-1 frequency and examine the correlation between HA-1 disparity and GVHD patients who received transplantation from a HLA-identical sibling. Samples and Methods: the DNA was extracted...
