Retinae from neonatal mice were explanted in toto, with or without the retinal pigment epithelium (RPE) and adjoining mesenchymal cells, and maintained in organ culture for up to 3 weeks. The explants remained flat, rosette formation was minimal and histogenetic changes followed in the normal sequence. After 11, 14 and 21 days in vitro the three cellular(More)
The elimination of two intravenously administered fat emulsions consisting of either 20% (wt:vol) soybean oil or 17% olive oil plus 3% soybean oil was studied in six normolipidemic young men according to a randomized crossover protocol. Slower elimination was found with the olive oil emulsion. A significantly lower maximal removal capacity (K1) and(More)
Normal subjects in steady state on a carbohydrate-rich diet (three equivalent meals a day at 9.00, 13.00 and 17.00 h), show a wave-like serum triglyceride (TG) pattern with a peak at 14.00 h. Post-heparin lipoprotein lipase (LPL) activity increased from a mean value of 49 mU/ml +/- 13 (SD) in the fasting state to 127 mU/ml +/- 18 in the fed state (P less(More)
BACKGROUND Intensive lowering of serum cholesterol may retard progression of coronary atherosclerosis in selected groups of patients. However, few data are available on the potential benefit of serum cholesterol reduction in the broad range of patients with coronary atherosclerosis and normal to moderately elevated serum cholesterol levels who undergo(More)
By lowering high density lipoprotein (HDL) cholesterol, testosterone contributes to the gender difference in HDL cholesterol and has been accused to be pro-atherogenic. The mechanism by which testosterone influences HDL cholesterol is little understood. We therefore investigated the effect of testosterone on the gene expression of apolipoprotein A-I(More)
To establish whether insulin resistance and/or postprandial fatty acid metabolism might contribute to familial combined hyperlipidemia (FCH) we have examined parameters of insulin resistance and lipid metabolism in six FCH kindreds. Probands and relatives (n = 56) were divided into three tertiles on the basis of fasting plasma triglycerides (TG).(More)
In the retina of mice homozygous for the retinal degeneration slow (rds) gene, receptor outer segments failed to develop and typical disc structures were never observed. However, cilia surrounded by a plasma membrane were regularly present. At the time when outer segments grew in the normal retina, the optic ventricle in the mutant showed an accumulation of(More)
Mice homozygous for the rds (retinal degeneration slow) gene fail to develop receptor outer segments and show a slow loss of visual cells that starts from 14-21 postnatal days and results in complete absence at 1 year. In the heterozygous rds/+ mice the development of receptor outer segments is initially retarded. Although a distinct layer of outer segments(More)
Cbl family members have an evolutionarily conserved role in attenuating receptor tyrosine kinase function. Their negative regulatory capacity depends on a Ring finger domain that interacts with ubiquitin conjugating enzymes. Cbl molecules constitute a novel type of E3 or ubiquitin ligase family that is recruited to phosphotyrosine motifs. Ubiquitination of(More)
Postprandial chylomicron remnant clearance was studied in six patients with familial combined hyperlipidemia (FCH) and seven control subjects by using an oral retinyl palmitate (RP) fat-loading test. The chylomicron remnant clearance (Sf < 1,000 fraction), expressed as the area under the RP curve (AUC-RP), was delayed in FCH subjects (65.05 +/- 12.84 hours(More)
