We have measured the hepatic secretion of very-low-density-lipoprotein apolipoprotein B-100 (VLDL apo B) in 6 patients with heterozygous familial hypercholesterolaemia (FH) (4 males, 2 females, age 47.0 +/- 2.7 years (mean +/- S.E.M.), weight 71.0 +/- 5.3 kg) and 6 normocholesterolaemic subjects matched for age, weight and sex (4 males, 2 females, age 47.5(More)
To assess the potential of various plasma lipoprotein classes to contribute to the lipid content of the arterial intima, influx and efflux of these plasma lipoprotein fractions into and from the intima of human carotid arteries were measured in vivo. While low density lipoprotein (LDL) is known to transfer from plasma into the arterial wall, there is less(More)
The plasma lipid and lipoprotein responses to two modified isoenergetic diets including meat were studied in 15 free living men with hyperlipidaemia (mean plasma cholesterol and triglyceride concentrations 8.1 and 3.4 mmol/l). A reference diet (diet A, 42% energy from fat, ratio of polyunsaturated to saturated fatty acids (P:S ratio) 0.2) was compared with(More)
We studied six patients with heterozygous familial hypercholesterolaemia (FH) before and after 8 weeks of treatment with simvastatin (40 mg day-1), an inhibitor of 3-hydroxy-3-methyl-glutaryl-Coenzyme A. Simvastatin decreased plasma low-density lipoprotein (LDL) cholesterol by 43% (P = 0.002), triglycerides by 15% [corrected] (P = 0.05) and mevalonic acid(More)
Low density lipoproteins extracted from surgical specimens of human atherosclerotic plaques (A-LDL) showed altered electrophoretic mobility indicating a greater negative charge than that of plasma LDL (P-LDL). A-LDL but not P-LDL showed high affinity binding/degradation by human monocyte-derived macrophages; this was inhibited by acetylated LDL but not by(More)
Maintenance of the balance of electrolytes and hormones within their normal range is necessary for normal myocardial metabolism. Open heart surgery involving cardiopulmonary bypass produces metabolic disturbances which affect normal metabolic homeostasis. Several studies have suggested that pulsatile cardiopulmonary bypass causes less severe metabolic(More)
A new method is proposed for measuring in vivo the rates of transfer of plasma lipoprotein into and out of arterial intima in man. The technique requires the injection of a lipoprotein which can be labelled with two different tracers, followed by a single arterial sample during elective surgery. The feasibility of the method was tested by computer(More)
OBJECTIVE Our prespecified dose-response analyses of A Very Early Rehabilitation Trial (AVERT) aim to provide practical guidance for clinicians on the timing, frequency, and amount of mobilization following acute stroke. METHODS Eligible patients were aged ≥18 years, had confirmed first (or recurrent) stroke, and were admitted to a stroke unit within 24(More)
Normal myocardial function is dependent on the metabolic balance of a number of electrolytes and hormones. The calcium ion plays a major role in muscle contraction and is rigorously controlled within narrow limits. Open-heart surgery imposes metabolic disturbances on both electrolytes and hormones, especially ionized calcium. Normally, ionized calcium(More)
