Primary cultures of human amniotic membrane (PCHAM) cells display very low proliferation rates while their doubling times vary between 150 h and 210 h even after mitogenic stimuli. However, the pattern of proto-oncogenes (c-fos, c-myc and c-jun) expression in these cells, upon serum restimulation, resembled that of cell lines that display shorter population(More)
BACKGROUND Peripheral blood lymphocyte (PBL) analysis by flow cytometry has been inconsistently reported as an adjunctive method for diagnosing acute kidney transplant rejection. However, there is good evidence that lymphocytes infiltrating renal grafts differ from those found at the peripheral level. We hypothesized that the study of aspiration biopsy(More)
PURPOSE The aim of this work is to evaluate the patient-reported health-related quality of life (HRQOL), according to the type and location of vascular access used for dialysis procedure. METHODS In this transversal study, 322 end-stage renal disease (ESRD) patients under online hemodiafiltration (OL-HDF, 59.63% males; 64.9±14.3 years) were enrolled.(More)
The presence and changes of estradiol nuclear binding and related functions in uterine luminal and glandular epithelium were studied before and after blastocyst implantation using receptor autoradiography with (3)H-estradiol-17beta in association with (3)H-thymidine incorporation and immunocytochemical binding of antibody to estrogen receptor ER-alpha.(More)
BACKGROUND The new immunosuppressive drug Rapamycin (Rapa) is endowed with a mechanism of action that is distinct from that of calcineurin inhibitors. It has been claimed that Rapa does not significantly modulate either the cytokine expression or the transcription of several growth factors in mitogen-activated T cells. Previously, we reported that(More)
BACKGROUND The urinary excretion of free dopamine has been used as an index of the renal synthesis of amine. However, it is now well recognized that in the kidney, newly-formed dopamine is significantly inactivated through deamination to 3,4-dihydroxyphenylacetic acid (DOPAC) by monoamine oxidase (MAO). The aim of the present study was to assess the renal(More)
OBJECTIVE Chronic renal failure is associated with metabolic derangements, affecting proteins, amino acids, and lipids. Usually these patients follow a restricted diet. Kidney transplant patients enjoy a recovery of renal function, but their therapeutics may entail significant changes in general metabolism. We compare the anthropometric results during the(More)
PURPOSE Patients' perception of health-related quality of life (HRQOL) is a consistent and powerful predictor of the outcome of end-stage renal disease (ESRD) patients under dialysis. This study aims to identify factors that could affect the HRQOL of ESRD patients under online hemodiafiltration (OL-HDF). METHODS We evaluated 322 ESRD patients under OL-HDF(More)
The aim of this work was to evaluate the predictors of mortality in a group of end-stage kidney disease (ESRD) patients under dialysis, by performing a three-year follow-up study. From the 236 patients included in this study, 54 patients died during the three-year follow-up period. Our data showed that the risk of death was higher in patients presenting(More)
