Chemopreventive Efficacy of Atorvastatin against Nitrosamine-Induced Rat Bladde...

To investigate the anti-carcinogenic effects of Atorvastatin (Atorva) on a rat bladder carcinogenesis model with N-butyl-N-(4-hydroxibutil)nitrosamine (BBN), four male Wistar rat groups were studied: (1) Control: vehicle; (2) Atorva: 3 mg/kg bw/day; (3) Carcinogen: BBN (0.05%); (4) Preventive Atorva: 3 mg/kg bw/day Atorva + BBN. A two phase protocol was used, in which the drug and the carcinogen were given betw...

Sitagliptin delays progression of renal lesions in a rodent model of type 2 dia...

Surgical complications in 2000 renal transplants

INTRODUCTION: Renal transplantation is the best treatment for end-stage renal disease. In the last years, we have seen improvements in immunosuppressive treatment, which have allowed patients to experience a better quality of life and graft survival. Nevertheless, surgical complications remain important problems that increase morbidity, mortality, costs, and hospitalization. Our purpose was to evaluate surgical...

Pancreatic lesions and metabolic aggravation are prevented by low doses of sita...

Introduction: The management of type 2 diabetes is designed to reduce disease-related complications and improve long-term outcomes. Inhibition of dipeptidyl peptidase-4 (DPP-4) activity by sitagliptin has been shown to improve glycaemic control in patients with type 2 diabetes Mellitus (T2DM) by prolonging the actions of incretin hormones, but the real impact of low-dose sitagliptin treatment on cardiometabolic...

Renal structure modification in an animal model of type 2 diabetes with aging: ...

Background and aims: The Zucker Diabetic Fatty (ZDF-fa/fa) rat is one of the most used models for the study of type 2 diabetes (T2DM). Characterization of renal morphology in this model may provide useful insights into the mechanism of diabetic nephropathy progression. The purpose of the present study was to determine renal morphology, identify and characterize renal dysfunction complications such as hydronephr...

Erythropoietin doping as cause of sudden death in athletes: an experimental study

Aims: To evaluate the cardiovascular (CV) effects of rhEPO treatment in rats under chronic aerobic exercise and to assess the probable cause of sudden death in one rat. Protocol: Male Wistar rats: control - sedentary; rhEPO - 50 IU/Kg/3xwk; swimming (EX) -1 hr, 3x/wk; EX+EPO. Hematology, catecholamines and serotonin, redox status and inflammation, were assessed. One rat of EX+EPO group suffered a sudden death e...

Hemorheological and cardiovascular effects of erythropoietin in a rat model of ...

Recombinant human erythropoietin (rhEPO) has been therapeutically used for correction of anaemia. However, due to the increase in circulating red blood cells (RBCs) it promotes, thus increasing oxygen delivery to muscles and improving performance in sport, it has been also illegally used as sports doping. Besides the well known increase of hematocrit and blood viscosity; which might cause serious complications ...

Caracterização hemorreológica, bioquímica e cardiovascular num modelo de doença...

Chronic kidney disease (CKD) is a major public health problem throughout the world. The major outcomes include a rapid progression, with development of anaemia and serious complications, namely thromboembol ic and cardiovascular events. The pathophysiological alterations depend on the CKD degree, which will also determine the moment to initiate hemodialysis and recombinant erythropoietin (rhEPO) therapies Thus,...

Effect of recombinant human erythropoietin in a rat model of moderate chronic r...

Background/Aims: Chronic renal failure (CRF) patients develop anaemia, thus promoting cardiovascular complications, which seems to be favoured by the low kidney erythropoietin (EPO) production. The renal insufficiency degree might determine the moment to start recombinant human EPO (rhEPO) therapy. It has been attributed important non-hematopoietic effects to rhEPO, which might underlie cardio and renoprotectio...

Anti-inflammatory, anti-proliferative and antioxidant profiles of selective cyc...

PURPOSE: To evaluate the efficacy of a selective cyclooxygenase-2 (COX-2) inhibitor in rat bladder cancer chemoprevention, as well as to assess the relevance of inflammation, proliferation and oxidative stress in tumor growth and in its prevention. RESULTS: The main findings were: (I) the incidence of carcinoma was: control: 0% (0/8); BBN: 65% (13/20); CEL: 0% (0/8) and BBN + CEL: 12.5% (1/8); (II) the mean tu...
