BACKGROUND Electronegative LDL [LDL(-)], a modified subfraction of LDL present in plasma, induces the release of interleukin-8 and monocyte chemotactic protein-1 from cultured endothelial cells. METHODS AND RESULTS We demonstrate that platelet-activating factor acetylhydrolase (PAF-AH) is mainly associated with LDL(-). LDL(-) had 5-fold higher PAF-AH(More)
The density distribution of electronegative LDL [LDL(-)], a cytotoxic and inflammatory fraction of LDL present in plasma, was studied in 10 normolipemic (NL), 6 FH, and 11 hypertriglyceridemic (HTG) subjects. Six LDL subclasses of increased density (LDL1 to LDL6) were isolated by density-gradient ultracentrifugation (DGU). NL and FH subjects showed(More)
Nanoinformatics has recently emerged to address the need of computing applications at the nano level. In this regard, the authors have participated in various initiatives to identify its concepts, foundations and challenges. While nanomaterials open up the possibility for developing new devices in many industrial and scientific areas, they also offer(More)
Electronegative low-density lipoprotein (LDL(-)) is a minor modified LDL subfraction that is present in blood. LDL(-) promotes inflammation and is associated with the development of atherosclerosis. We previously reported that the increase of cytokine release promoted by this lipoprotein subfraction in monocytes is counteracted by high-density lipoprotein(More)
Electronegative low density lipoprotein (LDL(-)) is a minor modified fraction of LDL found in blood. It comprises a heterogeneous population of LDL particles modified by various mechanisms sharing as a common feature increased electronegativity. Modification by oxidation is one of these mechanisms. LDL(-) has inflammatory properties similar to those of(More)
BACKGROUND Two-dimensional (2D) barcoding has the potential to enhance documentation of vaccine encounters at the point of care. However, this is currently limited to environments equipped with dedicated barcode scanners and compatible record systems. Mobile devices may present a cost-effective alternative to leverage 2D vaccine vial barcodes and improve(More)
UNLABELLED A Help Desk (HD) is crucial in a computerized hospital. OBJECTIVE to describe the performance of a HD. DESIGN retrospective cohort study. RESULTS the sociodemographic characteristics of users, as well as their relationship with the institution influence behaviour when requesting support to a HD. Also we observed a relationship between the(More)
Medication errors are responsible for most inpatient adverse events. Medication reconciliation emerged as an effective strategy to decrease these problems, enhancing patient safety. Electronic health records with reconciliation tools could improve the process, but many aspects should be considered in order to reach expected outcomes. In this paper we(More)
When a new Electronic Health Record is implemented or modifications are made, the full acceptance by end users depends on their expectations and perceptions about the possible benefits and the potential impacts on care quality. The redesign of an electronic nurse chart should consider the inherent characteristics of nurses' practice and the variables that(More)
In clinical practice, nurses perform different activities that exceed direct care of patients, and influence workload and time administration among different tasks. When implementing changes in an electronic nursing record, it is important to measure how it affects the time committed to documentation. The objective of this study was to determine the time(More)
