BACKGROUND End-stage renal disease patients have a dysfunctional, prematurely aged peripheral T-cell system. Here we hypothesized that the degree of premature T-cell ageing before kidney transplantation predicts the risk for early acute allograft rejection (EAR). METHODS 222 living donor kidney transplant recipients were prospectively analyzed. EAR was defined as biopsy proven acute allograft...

647 Credits have traditionally served as an incentive for physicians to participate in the continuing medical education (CME), which is the means for lifelong learning. The public at large has granted special rights to the profession of medicine giving them their most precious commodity; their lives. The providers of CME have a responsibility to maintain and update physicians' knowledge and com...

Sensitized candidates for heart transplant usually end up on a long waiting list and have an increased risk of rejection, graft loss, and incidence of cardiac allograft vasculopathy. An increasing number of studies have demonstrated the negative effect of preformed and posttransplant antibodies on graft survival. Thus, in sensitized patients, the combination of new, appropriate, desensitization...

Transfusion of crossmatch-incompatible red blood cells (RBCs) can result in antibody-mediated hemolysis. However, in some patients, crossmatch-incompatible RBCs lose the incompatible antigen from their surface, and then circulate normally ("antigen loss"). Although antigen loss has been reported in the settings of autoimmune hemolytic anemia and transfusion of crossmatch-incompatible RBCs, mech...

We consider the strong rescattering effects that can occur in the decays such as B → Kπ, Kπ, Kρ . . . and their impact on direct CP violation in these modes. First we discuss, in general, how the CPT theorem constrains the resulting pattern of partial rate asymmetries leading to different brands of direct CP. Traditional discussions have centered around the absorptive part of the penguin graph ...

The clinical merit of surveillance kidney graft biopsies remains controversial. A retrospective, multicenter analysis evaluated 12-month surveillance biopsies (SB, 154 patients) versus no SB (NSB, 138 patients (11 with diagnostic biopsy)) in patients >18 months posttransplant with estimated GFR (eGFR) ≥30 mL/min. The primary objective was to describe renal function at 18 months post-transplant ...

BACKGROUND Group II allergens are a major cause of sensitization in patients allergic to mites. To facilitate the antigenic analysis of group II allergens and to develop improved methods of allergen detection, we compared IgG anti-group II antibody responses in inbred mouse strains and raised a panel of monoclonal antibodies (mAbs). METHODS IgE antibody responses were compared by antigen-bind...

The Fcg receptor IIIb (FcgRIIIb) for the Fc domain of IgG is expressed exclusively on neutrophils. The FcgRIIIb bears allotypic polymorphisms referred to as NA1, NA2, and SH, which are known for their frequent involvement in alloimmune and autoimmune neutropenias as well as in transfusion reactions. The bactericidal capacity of isolated neutrophils is easily activatable, and activation results ...

OBJECTIVES The relevance of anti-HLA antibodies in patients awaiting kidney transplants is well recognized. During the past 40 years, kidney transplant candidates have been tested for these antibodies, and the choice of the detection assay has become essential. Recently, the pioneer method, the complement-dependent cytotoxicity, has been integrated but has not been replaced by more-sensitive so...

Anti-HER2 antibody conjugated with quantum dots (anti-HER2ab-QDs) is a very recent fluorescent nanoprobe for HER2+ve breast cancer imaging. In this study we investigated in-vivo toxicity of anti-HER2ab conjugated CdSe/ZnS QDs in Wistar rats. For toxicity evaluation of injected QDs sample, body weight, organ coefficient, complete blood count (CBC), biochemistry panel assay (AST, ALT, ALP, and GG...
