A moderate fish intake increases plasminogen activator inhibitor type-1 in human volunteers

For a period of 6 weeks, 76 healthy male volunteers consumed during their daily main meal the contents of one tin (~ 135 g) of either fish (mackerel) paste or meat paste. Fibrinolytic parameters were determined in plasma samples obtained at the beginning and at the end of the experimental period. No changes were found in plasminogen, α2...

Effects of vehicle handling characteristics on driving strategy

The time-to-line-crossing (TLC) concept has been used as a time-related measure to describe driving strategy. The purpose of this research is to analyze whether TLC might enlarge our understanding of the relationship between vehicle handling characteristics and a driver's looking and lateral control strategy in a straight-lane-keeping task....

Renal and hepatic handling of endogenous tissue-type plasminogen activator (t-PA) and its inhibitor in man

In eight male patients with normal liver and kidney function fibrinolytic components were measured in arterial blood and in renal and hepatic vein blood, obtained during catheterization for analysis of hypertension. Blood samples were collected simultaneously from veins und corresponding arteries before and 5 minutes after the completion of...

The negative effect of amplitude compression in multichannel hearing aids in the light of the modulation transfer funtion

The article deals with the question of why multichannel amplitude compression appears to have a negative rather than a positive effect no speech intelligibility by hearing-impaired listeners. It is argued that the small time constants of amplitude compression diminish the temporal as well as the spectral contrasts in the speech signal. According...

Effects of moderate alcohol consumption on platelet aggregation, fibrinolysis, and blood lipids

To investigate the effect of moderate alcohol consumption on blood constituents related to cardiovascular disease, 12 male volunteers consumed (instead of their usual alcoholic drinks) four different standardized amounts of red wine in addition to their habitual diet. Each dose was given to the subjects during a period of 5 weeks in a randomized...

Urinary excretion of 3-methylhistidine and creatinine by healthy Dutch children during day and night. The influence of age and sex

The urinary excretion of 3-methylhistidine and creatinine and the urinary 3-methylhistidine to creatinine excretion ratio during day and night were investigated in a group of 103 healthy, normally fed Dutch children (52 boys and 51 girls) aged 2-17 years. The 3-methylhistidine to creatinine ratio of the night urine appeared to be significantly...

Vehicle control during curve driving

Based on a preview-predictor model, the time-to-line crossing (TLC) description was developed to quantify the potential role of error-neglecting strategies in driving. In a previous study the usefulness of the TLC concept was illustrated for straight lane keeping. In the present analysis TLC was applied to describe steering through a curve. When...

Vitamins and endurance training: Food for running or faddish claims?

The inter-relationship of food and physical performance, food is considered as a conglomerate of nutrients and man is depicted as a kind of organic pudding. This 'machine' concept of human performance in combination with the mysticism surrounding vitamins, has led to the faddish belief that additional vitamins are necessary to improve physical...

Effect of low-dose oral contraceptives on lipoproteins and lipolytic enzymes: Differences between two commonly used preparations

Changes in circulating lipoproteins, which may be related to the risk for atherosclerotic vascular disease, were studied in a control group and in two groups of 24 or 26 women using different preparations of low-dose oral contraceptives for 3 months. One preparation contained 150 μg levo-norgestrel and 30 μg ethinylestradiol (Stediril-d 150/30);...
