AIM To investigate the relationship between serum content of n-3 polyunsaturated fatty acids (PUFA) and the incidence of ventricular arrhythmias in patients with an implantable cardioverter defibrillator (ICD). METHODS We included 98 patients with ischaemic heart disease and an ICD. The numbers of ventricular fibrillation (VF) and ventricular tachycardia(More)
We report a functional characterization of the W23X and W66G low density lipoprotein (LDL) receptor gene mutations. The authors used two-color fluorescence flow cytometry to measure LDL receptor activity in stimulated T-lymphocytes, prepared from patients heterozygous for the W23X or W66G mutation, and compared the results with measurements of LDL receptor(More)
Fifteen anesthetised pigs (25-30 kg) were divided into three equal groups, sham, dopexamine (D) (10 micrograms/kg/min), and placebo (P). Sepsis was induced by fecal peritonitis in the D and P groups and colloid was infused to try to maintain mean arterial blood pressure (MABP) at a constant value and the hemodynamics measured at baseline and hourly for 8(More)
BACKGROUND Studies indicate that human peripheral blood mononuclear cells mirror low-density lipoprotein (LDL) receptor activity of other cells in the body. To measure LDL receptor activity in patients with heterozygous familial hypercholesterolemia (FH), we prepared peripheral blood mononuclear cells from individuals with molecularly verified LDL receptor(More)
The aim of this study was to evaluate whether the incidence of ventricular arrhythmias and heart rate variability were influenced by statin treatment and lipid levels in patients treated with an implantable cardioverter defibrillator (ICD). Heart rate variability measurements were performed in 86 patients with coronary heart disease and an ICD implant. The(More)
Mutations in genes are not necessarily pathogenic. Expression of mutant genes in cells can therefore be required to demonstrate that mutations in fact disturb protein function. This applies especially to missense mutations, which cause an amino acid to be replaced by another amino acid. In the present study of two families with familial hypercholesterolemia(More)
In a group of unrelated Danish patients with familial hypercholesterolemia (FH) we recently reported two common low-density lipoprotein (LDL) receptor mutations, W23X and W66G, accounting for 30% of the cases. In this study, we describe another common LDL receptor mutation, a G to C transition at cDNA position 1730 in exon 12, causing a tryptophan to serine(More)
We used a fluorescence flow cytometry assay with a monoclonal low density lipoprotein (LDL) receptor-specific antibody to detect LDL receptor expression on blood T lymphocytes and monocytes. We prepared peripheral blood mononuclear cells from patients with genetically verified LDL receptor-defective (Trp66-Gly mutation, n = 17) or receptor-negative(More)
To characterize disease-causing mutations in the low density lipoprotein receptor (LDL-R) gene, COS cells are transfected with the mutant gene in an EBV-based expression vector and characterized by flow cytometry. Using antibodies against the LDL-receptor the amount of receptor protein on the cell surface is quantitated. The receptor activity is measured by(More)
