We investigated the role of cardiomyocyte apoptosis in the remodeling of the left ventricle from 24 h to 12 wk after myocardial infarction in the rat. Infarct size planimetry, quantification of cardiomyocyte apoptosis, terminal deoxynucleotide transferase-mediated dUTP nick-end labeling (TUNEL) methodology, and echocardiography (left ventricular diastolic(More)
BACKGROUND The recently identified gene NPHS1 with its mutations causing congenital nephrotic syndrome of the Finnish type (CNF) is highly promising in providing new understanding of pathophysiology of proteinuria. Earlier we cloned a rat NPHS1 homologue, as well as characterized and raised antibodies to the respective protein product nephrin. METHODS(More)
Endothelial dysfunction is associated with hypertension, hypercholesterolemia, and heart failure. We tested the hypothesis that spontaneously diabetic Goto-Kakizaki (GK) rats, a model for type 2 diabetes, exhibit endothelial dysfunction. Rats also received a high-sodium diet (6% NaCl [wt/wt]) and chronic angiotensin type 1 (AT(1)) receptor blockade (10(More)
Activation of the complement (C) system has been documented in both experimental and clinical studies of myocardial infarction, but the exact time course and mechanisms leading to C activation have remained unclear. Our earlier postmortem study on human beings showed that formation of the membrane attack complex (MAC) of C was associated with loss of CD59(More)
Heymann nephritis developed in rats immunized with brush border membrane fractions isolated from rat kidney tubules. Glomerular autoantibodies eluted from cryostat sections of nephritic kidneys reacted in immunoelectron microscopy with the outer surface of isolated brush border membrane vesicles. This indicates that the autoantigens are plasma membrane(More)
BACKGROUND Hypertension, a known independent risk factor for end-stage renal failure, damages the kidney in multiple ways. It produces hemodynamic and mechanical stress, which may lead to glomerular endothelial dysfunction. Both of these mechanisms may lead to increased glomerular leakiness, hence proteinuria, which may damage the kidney further.(More)
BACKGROUND Only a minority of hypertensive individuals is adequately controlled for their hypertension, partially because reliable predictors for efficient antihypertensive drug therapy are lacking. METHODS In a prospective, randomized, double-blind, cross-over, placebo-controlled study (The GENRES Study), 208 moderately hypertensive Finnish men (aged 35(More)
OBJECTIVES To assess and compare the effects of candesartan or lisinopril, or both, on blood pressure and urinary albumin excretion in patients with microalbuminuria, hypertension, and type 2 diabetes. DESIGN Prospective, randomised, parallel group, double blind study with four week placebo run in period and 12 weeks' monotherapy with candesartan or(More)
Myoblast sheet transplantation is a promising novel treatment modality for heart failure after an ischemic insult. However, low supply of blood and nutrients may compromise sheet survival. The aim of this study was to investigate the effect of mitochondria-protective Bcl-2-modified myoblasts in cell sheet transplantation therapy. In the Bcl-2-expressing rat(More)
Heme oxygenase-1 (HO-1) is a cytoprotective enzyme, which regulates cell proliferation and has potential antifibrogenic properties. In the present study, we investigated the effects of pre-emptive HO-1 induction by cobalt protoporphyrin IX on the healing of myocardial infarction in rats. The proliferation and repair of cardiac cells was assessed by(More)
