The metabolic syndrome is associated with insulin resistance, a systemic low-grade inflammatory state, and endothelial dysfunction. These disorders may arise at a very early age in obese children. The aim of this study was to confirm changes in endothelial dysfunction and inflammatory biomarkers in obese prepubertal children and to evaluate the effect of(More)
The ability of a bacterial population to survive in different niches, as well as in stressful and rapidly changing environmental conditions, depends greatly on its genetic content. To survive such fluctuating conditions, bacteria have evolved different mechanisms to modulate phenotypic variations and related strategies to produce high levels of genetic(More)
The aim of this study was to detect the presence and degree of impairment of cardiovascular disease (CVD) risk factors, grouped as metabolic cardiovascular syndrome (MCS), in obese prepubertal children. We also assessed the influence of high fasting insulin levels in this pathological status. A cross-sectional study was performed on obese children based on(More)
Obesity is an independent risk factor for the development of cardiovascular disease frequently associated with hypertension, dyslipemia, diabetes, and insulin resistance. Higher homocysteine (Hcy) levels are observed in the hyperinsulinemic obese adults and suggest that Hcy could play a role in the higher risk of cardiovascular disease in obesity. We(More)
Vibrio cholerae O1 biotype El Tor (ET), the cause of the current 7th pandemic, has recently been replaced in Asia and Africa by an altered ET biotype possessing cholera toxin (CTX) of the classical (CL) biotype that originally caused the first six pandemics before becoming extinct in the 1980s. Until recently, the ET prototype was the biotype circulating in(More)
Vibrio cholerae O1 classical (CL) biotype caused the fifth and sixth pandemics, and probably the earlier cholera pandemics, before the El Tor (ET) biotype initiated the seventh pandemic in Asia in the 1970s by completely displacing the CL biotype. Although the CL biotype was thought to be extinct in Asia and although it had never been reported from Latin(More)
Chronic inflammation of the intestinal mucosa is characteristic of inflammatory bowel diseases such as ulcerative colitis and Crohn's disease. Helminth parasites have developed immunomodulatory strategies that may impact the outcome of several inflammatory diseases. Therefore, we investigated whether Taenia crassiceps infection is able to decrease the(More)
BACKGROUND/AIMS The metabolic syndrome (MS) is associated with insulin resistance (IR), inappropriate fibrinolysis and high plasma leptin concentrations. The aim of this study was to quantify fibrinolysis and MS-related variables in obese prepubertal children and to evaluate changes in these variables as a result of improved body mass index (BMI), IR and(More)
