Atypical hemolytic and uremic syndrome (aHUS) is a severe disease strongly associated with genetic abnormalities in the complement alternative pathway. In renal posttransplantation, few data are available on recurrence risk and graft outcome according to genetic background in aHUS patients. The aim of this study was to identify risk factors for recurrence(More)
BACKGROUND There have been few prospective studies on the natural history of nonadherence (NA) in kidney transplant recipients (KTRs) over time. The objective of this study was to prospectively evaluate the rate of and risk factors for NA in a French cohort of KTRs. METHOD A total of 312 KTRs from eight French transplantation centers were included in this(More)
BACKGROUND To define the role of mammalian target of rapamycin inhibitors in kidney transplantation, we compared efficacy and safety of two immunosuppressive regimens-a calcineurin inhibitor-free regimen with depletive induction versus a calcineurin inhibitor-based regimen. METHODS De novo renal allograft recipients were randomized before transplantation(More)
We have used a sensitive gel electrophoresis assay to detect the products of Escherichia coli RecA protein catalysed strand exchange reactions between gapped and duplex DNA molecules. We identify structures that correspond to joint molecules formed by homologous pairing, and show that joint molecules are converted by RecA protein into heteroduplex monomers(More)
The concerted action of DNA gyrase and RecA protein of Escherichia coli on intact and gapped homologous or partially homologous plasmid DNA molecules leads to the formation of covalently closed DNA containing one strand of each parental molecule. Large regions of non-homology can be incorporated into the closed circular duplex. Both proteins are essential(More)
There is increasing interest in tacrolimus-minimization regimens. ASSET was an open-label, randomized, 12-month study of everolimus plus tacrolimus in de-novo renal-transplant recipients. Everolimus trough targets were 3-8 ng/ml throughout the study. Tacrolimus trough targets were 4-7 ng/ml during the first 3 months and 1.5-3 ng/ml (n = 107) or 4-7 ng/ml (n(More)
The product of the uvrD gene of Escherichia coli, UvrD (helicase II), is known to be involved in methyl-directed mismatch repair, transposon excision and uvrABC excision repair. In conjugational crosses, various uvrD mutants have been reported to result in higher, lower or unaffected recombination frequencies. In an attempt to clarify the role of UvrD in(More)
BACKGROUND Infections of renal grafts with Candida species can induce life-threatening complications in the recipient. METHODS A 9-year retrospective study involving all of the transplant centers in France was designed to determine the incidence, origin, characteristics, and outcome of graft-site candidiasis that occurred after kidney transplantation.(More)
