BACKGROUND G-CSF is a critical regulator of hematopoietic cell proliferation, differentiation and survival. It has been reported that G-CSF attenuates renal injury during acute ischemia-reperfusion. In this study we evaluated the effects of G-CSF on the renal and cardiovascular systems of 2K1C hypertensive mice. METHODS Male C57BL/6 mice were subjected to(More)

Coronary artery disease is the leading cause of death in the developed world and in developing countries. Acute mortality from acute myocardial infarction (MI) has decreased in the last decades. However, the incidence of heart failure (HF) in patients with healed infarcted areas is increasing. Therefore, HF prevention is a major challenge to the health(More)
BACKGROUND/AIM Granulocyte colony-stimulating factor (G-CSF) reduces myocardial injury and improves cardiac function after myocardial infarction (MI). We investigated the early alterations provided by G-CSF and the chronic repercussions in infarcted rats. METHODS Male Wistar rats (200-250g) received vehicle (MI) or G-CSF (MI-GCSF) (50 μg/kg, sc) at 7, 3(More)
BACKGROUND Hypertension and metabolic syndrome are cardiovascular risk factors associated with increased adiposity. In a previous study, waist-to-stature ratio (WSR) was identified as the best obesity index associated with left ventricular hypertrophy. OBJECTIVE In this study we compared the ability of this index to identify hypertension and metabolic(More)
BACKGROUND The growing epidemic of metabolic syndrome has been related to the increased use of fructose by the food industry. In fact, the use of fructose as an ingredient has increased in sweetened beverages, such as sodas and juices. We thus hypothesized that fructose intake by hypertensive rats would have a worse prognosis in developing metabolic(More)
The main purpose of this study was to investigate the effects of short-term L-NAME treatment on the contractile function of left ventricle (LV) myocytes and the expression of proteins related to Ca(2+) homeostasis. Data from Wistar rats treated with L-NAME (L group, n = 20; 0.7 g/L in drinking water; 7 days) were compared with results from untreated(More)
Our aim was to evaluate the effects of granulocyte colony-stimulating factor (G-CSF) on early cardiac arrhythmias after myocardial infarction (MI) and the impact on survival. Male Wistar rats received repeated doses of 50 mug/kg G-CSF (MI-GCSF group) or vehicle (MI group) at 7, 3, and 1 days before surgery. MI was induced by permanent occlusion of left(More)
BACKGROUND Cardiovascular diseases are the leading cause of death in the majority of developed and developing countries. African countries are currently facing an increase in both cardiovascular and transmitted diseases. In addition, cardiovascular risk varies among different socioeconomic groups. Thus, we determined the prevalence of modifiable(More)
BACKGROUND There is no data concerning the epidemiology of hyperuricemia in Brazilian population-based studies. OBJECTIVE To investigate the distribution of serum uric acid and its relationship with demographics and cardiovascular variables. METHODS We studied 1,346 individuals. Hyperuricemia was defined as ≥ 6.8 and ≥ 5.4 mg/dL for men and women,(More)
This work assessed the influence of the autoregressive model order (ARMO) on the spectral analysis of the heart rate variability (HRV). A sample of 68 R-R series obtained from digital ECG records of young healthy adults in the supine position was used. Normalized spectral indexes for each ARMO were compared by Friedman test followed by the Dunn's procedure(More)
