13. Superimposing a high-fat diet on Schistosoma mansoni infection affects renin-angiotensin system components in the mouse kidney
Abstract INTRODUCTION: The levels of the full-length form of the (pro)renin receptor (PRR), a component of the renin-angiotensin system (RAS), may be reduced in the membranes of kidneys in renal diseases. This study aimed to investigate the RAS components in the kidneys of mice submitted to a combination of a high-fat diet and Schistosoma mansoni infection.

14. Effects of Aliskiren, an RAAS inhibitor, on a carrageenan-induced pleurisy model of rats
Abstract Our aim is to investigate the potentially preventive effects of Aliskiren in a carrageenan-induced lung pleurisy model and to compare the standard anti-inflammatory agents, indomethacin and dexamethasone. The pleurisy model was induced through the injection of carrageenan (0.2 ml-%2) into the pleural cavity. After the experiment, serum and lung tiss

15. Renovascular hypertension increases serum TNF and CX3CL1 in experimental Trypanosoma cruzi infection
Trypanosoma cruzi triggers a progressive inflammatory response affecting cardiovascular functions in humans and experimental models. Angiotensin II, a key effector of the renin-angiotensin system, plays roles in mediating hypertension, heart failure, and inflammatory responses. T. cruzi and AngII can induce inflammatory responses by releasing inflammatory me

16. The Evolving Role of Erythropoietin in Lung of Irradiated Rats
ABSTRACT The aim of the present study is to evaluate the possible curative effect of erythropoietin (EPO) on radiation-induced damage to the lung and its renin angiotensin system. EPO (200 U/100g) was i.p. injected to male rats one hour post 6 Gy whole body gamma irradiation. The animals were sacrificed after 14 days post irradiation. Irradiation induced sig

17. Effects of warming yang and invigorating qi prescription on renin-angiotensin-aldosterone system in rats with heart failure after myocardial infarction
Abstract This study investigated the effects of warming yang and invigorating qi prescription on renin-angiotensin-aldosterone system (RAAS) in rats with heart failure after myocardial infarction. 126 rats were randomly divided into model group, sham operation, warming yang, invigorating qi, warming yang+invigorating qi, digoxin and captopril group for respe

18. Renin-angiotensin system blockers regulate the metabolism of isolated fat cells in vitro
Due to the presence of the renin-angiotensin system (RAS) in tissues and its specific influence on white adipose tissue, fat cells are possible targets of pharmacological RAS blockers commonly used as anti-hypertensive drugs. In the present study, we investigated the effects of different RAS blockers on fat cell metabolism, more specifically on lipolysis, li

19. Relationship between major depressive disorder and ACE gene I/D polymorphism in a Turkish population
Abstract Background Major depressive disorder (MDD) is a complex disease and a significant health problem that is prevalent across the world. Angiotensin-converting enzyme (ACE) has an important role in renin-angiotensin system (RAS) and converts inactive angiotensin I to a potent vasopressor and aldosterone-stimulating peptide angiotensin II. Levels of AC

20. Association of polymorphisms within the Renin-Angiotensin System with metabolic syndrome in a cohort of Chilean subjects
ABSTRACT Objective Metabolic syndrome (MetS) is associated with hypertension, obesity and dyslipidemia. Thus, genetic variants related with these conditions may modulate its development. We evaluated the effect of polymorphisms in the renin-angiotensin system (RAS) on metabolic syndrome risk in a cohort of Chilean subjects. Subjects and methods A total of

21. Sociodemographic characteristics and clinical features of patients with adult polycystic kidney disease undergoing hemodialysis; Características sociodemográficas e aspectos clínicos de pacientes com doença renal policística do adulto submetidos a hemodiá
AIMS: To analyze the sociodemographic and clinical characteristics of patients with adult polycystic kidney disease admitted to hemodialysis services in Northwestern Paraná state, Brazil. METHODS: This was an observational, descriptive and retrospective longitudinal study. Medical records of patients with polycystic kidneys who initiated hemodialysis betwee

Introduction: Autosomal dominant polycystic kidney disease is the most common hereditary renal disease in humans. Objective: To examine the prevalence, clinical and laboratory characteristics of patients with polycystic kidneys and relate disease manifestations by gender. Methods: This was an observational and retrospective study. All the medical records of

23. Resveratrol inhibits the intracellular calcium increase and angiotensin/endothelin system activation induced by soluble uric acid in mesangial cells
Resveratrol (Resv) is natural polyphenol found in grapes. This study evaluated the protective effect of Resv against the effects of uric acid (UA) in immortalized human mesangial cells (ihMCs). ihMCs were preincubated with Resv (12.5 µM) for 1 h and treated with UA (10 mg/dL) for 6 or 12 h. The intracellular calcium concentration [Ca2+]i was quantified by f

24. Combined aliskiren and L-arginine treatment has antihypertensive effects and prevents vascular endothelial dysfunction in a model of renovascular hypertension
Angiotensin II is a key player in the pathogenesis of renovascular hypertension, a condition associated with endothelial dysfunction. We investigated aliskiren (ALSK) and L-arginine treatment both alone and in combination on blood pressure (BP), and vascular reactivity in aortic rings. Hypertension was induced in 40 male Wistar rats by clipping the left rena
