BACKGROUND Many health care centers worldwide use the Platelia Aspergillus enzyme immunoassay (PA-EIA; Bio-Rad Laboratories) for diagnosis of invasive aspergillosis (IA). A cutoff optical density (OD) index of 1.5 was originally recommended by the manufacturer, but in practice, most institutions use lower cutoff values. Moreover, a cutoff OD index of 0.5(More)
Cell lines are widely used to monitor drug pharmacokinetics and pharmacodynamics and to investigate a number of biochemical mechanisms. However, little is known about the genetic profile of these in vitro models. To analyze genetic profile of Thp1, U937, HL60, K562, HepG2, Kyn2, and Caco2 human cell lines with a focus on genetic variations within genes(More)
Endothelial cells and smooth muscle cells are the major cells that constitute blood vessels, and endothelial cells line the lumen of blood vessels. These 2 types of cells also play an integral role in the regional specialization of vascular structure. On the basis of these observations, we designed our study to investigate the effect of various statins on(More)
BACKGROUND Although numerous genetic studies have been performed, only 0.9% of blood pressure phenotypic variance has been elucidated. This phenomenon could be partially due to epistatic interactions. Our aim was to identify epistatic interaction(s) associated with blood pressure levels in a pre-planned two-phase approach. METHODS AND RESULTS In a(More)
BACKGROUND The extended role of vascular endothelial growth factor (VEGF) in human pathophysiology led us to evaluate pre-analytical parameters possibly influencing its levels in peripheral blood and tissues. The effects on VEGF protein levels and mRNA expression were measured after storage delay (blood and tissue), use of different types of anticoagulants(More)
Vascular endothelial growth factor (VEGF), a key regulator of blood vessel function during angiogenesis, has been related to various diseases including atherosclerosis, neurodegenerative disorders and cancers. However, data about genetic determinants of its concentration in blood are scarce. The present study aimed at estimating additive genetic(More)
BACKGROUND Human formyl peptide receptor 1 (FPR1) mediates inflammatory responses, recognized as important participants in the physiopathology of hypertension. Similarly, FPR1 C32T SNP is associated with inflammation and BP related pathways. Therefore, the relationship between FPR1 C32T SNP, BP and hypertension needs to be investigated.

BACKGROUND AND AIMS Genome-wide linkage analysis studies reported the importance of the long arm of chromosome 13 in systolic blood pressure regulation. Therefore, isolating a genetic variant related to this chromosomal region could be challenging. Klotho KL-VS allele is located on this chromosomal region and its relationships with cardio-vascular risk(More)
CONTEXT AND OBJECTIVE Previous in vitro studies have shown a relationship between epidermal growth factor (EGF) and lipid metabolism. Indeed, EGF is able to modulate lipoprotein fractions in human fetal intestine and hepatic-derived cell lines. The aim of this study was to search for potential associations between EGF concentrations and lipid parameters in(More)
