Retinol binding protein 4 (RBP4) is an adipokine that may contribute to the development of insulin resistance. However, how this adipokine is affected and its possible involvement in lipid metabolism in obese patients with varying degrees of insulin resistance is yet to be determined. A total of 299 middle-aged morbid obese patients (BMI>40 kg/m(2)) were(More)
A limited amount of research suggests that oral ingestion of pinitol (3-O-methyl-d-chiro-inositol) positively influences glucose tolerance in humans. This study assessed the effects of different doses of pinitol supplementation on glucose tolerance, insulin sensitivity and plasma pinitol concentrations. Thirty healthy subjects underwent two one-day trials(More)
Overproduction of reactive oxygen species (ROS) under pathophysiologic conditions is part of the disease process. These ROS are released from different sources, and in particular from mitochondria. Although the molecular mechanisms responsible for mitochondria-mediated disease processes are unclear, oxidative stress seems to play an important role. ROS are(More)
We have developed a new procedure for turbidimetric measurement of ferritin concentration in human serum, based on latex microparticle agglutination technology. The procedure has been automated using the Falcor 300 analyzer. Carboxilated latex particles (336 nm in diameter) were covalently coupled with immunopurified F(ab')2 fragments of anti-ferritin IgG(More)
OBJECTIVE Subclinical hypothyroidism (SCH) is a common condition associated with increased cardiovascular risk. A standard treatment is yet to be established, as there is no consensus on the TSH cut-off values which should be used as indicators. Thus, the aim of this study was to assess cardiovascular risk in patients with SCH and to differentiate it(More)
OBJECTIVE Diabetes is associated with oxidative stress and increased mortality, but a possible correlation between leukocyte-endothelium interactions, oxidative stress, and silent myocardial ischemia (SMI) is yet to be confirmed. RESEARCH DESIGN AND METHODS Mitochondrial dysfunction and interactions between leukocytes and human umbilical vein endothelial(More)
CML with exclusive expression of ALL-type bcr/abl has only been rarely described. In some cases, the presence of this fusion gene has been associated to a differentiated subtype of CML that share some features with CMML, while in another case this molecular hallmark has been associated to a bad prognosis of the disease with a blast phase as clinical(More)
Phytosterols, which are structurally related to cholesterol, are found in all plant foods with highest concentration occurring in vegetable oils and nuts. Phytosterols are known to reduce serum low-density lipoprotein cholesterol level without changing high-density lipoprotein cholesterol or triglyceride levels. Daily consumption of phytosterols-enriched(More)
BACKGROUND The measurement of small dense low-density lipoprotein (sdLDL) particles is relevant when assessing cardiovascular risk. However, there is as yet no referenced method for the determination of LDL subfractions or a standardized comparison of the methods currently available. Therefore, the aim of this study was to compare the pattern of LDL(More)
