BACKGROUND The pleiotropic actions of statins have been largely explored. These drugs have been tested in several models of progressive renal disease, most of them accompanied by hypertension. We sought to investigate more closely the effects of simvastatin on renal interstitial fibrosis due to unilateral ureteral obstruction (UUO). METHODS Munich-Wistar(More)
BACKGROUND Vascular calcification (VC) is commonly seen in patients with chronic kidney disease (CKD). Elevated levels of phosphate and parathormone (PTH) are considered nontraditional risk factors for VC. It has been shown that, in vitro, phosphate transforms vascular smooth muscle cells (VSMCs) into calcifying cells, evidenced by upregulated expression of(More)
OBJECTIVES Chronic kidney disease is a major public health problem worldwide. In Brazil, approximately 100,000 patients (January 2012) receive renal replacement therapy. Nevertheless, data on dialysis incidence in the Brazilian population are scarce. This study aims to analyze the incidence of patients starting dialysis therapy in São Paulo City, the(More)
BACKGROUND Mesenchymal stromal cells (MSCs) represent an option for the treatment of acute kidney injury (AKI). It is known that young stem cells are better than are aged stem cells at reducing the incidence of the senescent phenotype in the kidneys. The objective of this study was to determine whether AKI leads to premature, stress-induced senescence, as(More)
Diabetes mellitus leads to increased Advanced Glycation End Products (AGE) production, which has been associated with secondary diabetic complications. Type 1 diabetic patients undergoing pancreas-kidney transplantation (SPKT) can restore normoglycemia and renal function, eventually decreasing AGE accumulation. We aimed to prospectively study AGE evolution(More)
A continuing medical education (CME) course was implemented for Latin American nephrologists in 2013. The topic was Immunopathology in native and transplanted kidneys. The course was given in Spanish and Portuguese. The activities included a distance education seven-week asynchronous online modality with multiple educational strategies. Thirty hours of(More)
Amniotic fluid (AF) contains a variety of cell types derived from fetal tissues that can easily grow in culture. These cells can be obtained during amniocentesis for prenatal screening of fetal genetic diseases, usually performed during the second trimester of pregnancy. Of particular interest, some expanded sub-populations derived from AF cells are capable(More)
