Pressure-volume (p-V) relationships of a segment of the forearm circulation have been measured in nine male healthy subjects. Forearm volume was measured using electrical impedance plethysmography, arterial transmural pressure by subtracting mean arterial pressure measured contralaterally in a finger from the pressure in a cuff placed over the...

Both in 6- and 12-year-old Dutch children the prevalence of dental caries has declined remarkably between 1970 and 1985. However, in 6-year-olds the decline terminated after that period, while it continued in the 12-year-olds. In 1986 a national dental survey of the caries prevalence of older age categories was executed. As no comparable caries...

A previous study has shown five-year-old children of parents originating from Turkey or Morocco to have twice as much dmfs as children of parents from The Netherlands, Surinam or various other countries. In the present study, other risk indicators and factors for the prevalence of caries amongst these children were studied by interviewing their...

4-Aminopyridine (4-AP) has a favorable effect on the disability of certain patients with MS. We investigated the effect of 4-AP on neuropsychological performance in 20 MS patients using a randomized, double-blind, placebo- controlled, crossover design. Although there was a trend for improved performance with 4-AP for two of the tests, we could...

Impaired fibrinolytic activity has been reported in the elderly and is thought to play a role in the etiology of cardiovascular disease, one of the leading causes of death in most Western countries. Since restriction of energy intake has been demonstrated to act beneficially on the aging process in a variety of species, we studied the effect of...

Postprandial response curves of β-carotene and retinyl esters in a triglyceride-rich lipoprotein (TRL) fraction were evaluated as a potential measure of β-carotene uptake and cleavage. β-Carotene, retinyl ester, and triglyceride concentrations in the TRI, fraction (density < 1.006 kg/L) and plasma were measured in 10 men for 8 or 16 h after an...

This study was designed to investigate local reactions after the intracutaneous (i.c.) administration of two human menopausal gonadotrophin preparations. For this purpose, 20 healthy female volunteers received six i.c. injections simultaneously, viz. three different batches of both Humegon (Organon, Oss, The Netherlands) and Pergonal (Serono,...

We investigated the effect of heparin on urinary albumin excretion in patients with insulin-dependent diabetes mellitus. 39 patients with persistent urinary albumin excretion of 30-300 mg/24 h were randomly treated for 3 months with subcutaneous injections twice daily of isotonic saline, 5000 IU unfractionated heparin, or 2000 anti-Xa IU low...

A high intake of β-carotene has been associated with a decreased risk for cardiovascular disease. To evaluate whether β-carotene may exert a protective effect through an impact on haemostasis a randomized, placebo-controlled trial was conducted in male smokers (n = 149) using 20 mg/day β-carotene for 14 weeks. For comparisons, haemostatic...

In this article the importance of mineral suppletion for teeth and jawbone is explained in a step-wise manner. The steps discussed are the pre-eruptive phase of teeth and the growth, adult and ageing phase of the skeleton. Mineral suppletion should be seen as a measure to prevent dental caries (fluoride) and to ensure a maximal resistance...

Restriction of energy intake (ER), without malnutrition of essential nutrients, has repeatedly been demonstrated to increase longevity in rodents. In the antioxidant theory of aging the lack of balance between the generation of free radicals and free radical scavenging was thought to be a main causal agent in the aging process. From this point...

OBJECTIVE - To assess possible changes in the incidence of diabetes in all age-groups in The Netherlands during a 10-year period (1980-1983/1990-1992). RESEARCH DESIGN AND METHODS - Since 1970, a network of sentinel stations (the Dutch Sentinel Practice Network) consisting of ∼1% of the Dutch population has been in operation to gain insight into...

The pathogenesis of multiple sclerosis (MS), the major neurological disease of young adults in the Western world, is still poorly understood, and no effective therapy to block MS is available as yet. The clinical symptoms of MS result from inflammatory damage to the insulating myelin sheath of axons in the CNS and - at later stages - to axons...

To assess the level of exposure to food contaminants (cadmium, lead, PCBs, DDT, hexachlorobenzene, nitrate and malathion) a total-diet study was carried out. A total of 226 food products were analysed individually; the concentration of contaminants in products not selected for analysis was estimated with the help of published data. The results...

Background. Experiments in animals, international correlation comparisons, and case-control studies support an association between dietary fat intake and the incidence of breast cancer. Most cohort studies do not corroborate the association, but they have been criticized for involving small numbers of cases, homogeneous fat intake, and...

The Equiratio Mixture Model predicts the psychophysical function for an equiratio mixture type on the basis of the psychophysical functions for the unmixed components. The model reliably estimates the sweetness of mixtures of sugars and sugar-alchohols, but is unable to predict intensity for aspartame/sucrose mixtures. In this paper, the...

Background: Disturbances of the fibrinolytic system that lead to decreased removal of fibrin deposits may be important risk factors for coronary thrombosis. There is as yet no consensus on the prognostic value of fibrinolytic parameters, which may be attributed in part to the choice of confounding variables controlled for. Methods and Results:...

Apolipoprotein E (apoE) is one of the major protein constituents of chylomicron and very low density lipoprotein (VLDL) remnants and plays a central role as a ligand in the receptor-mediated uptake of these particles by the liver. Here we describe a new variant of apoE, apoE1-Hammersmith, which is associated with dominantly expressed type III...

1. In order to study the antigenotoxic potential of eugenol in humans, ten healthy non-smoking males ingested a daily amount of 150 mg eugenol or the placebo for seven consecutive days. After a washout period of one week, groups ingesting eugenol or the placebo were crossed and received the other treatment for seven consecutive days. 2. On days...
