In a previous study we demonstrated that beta-endorphin (beta-end) may stimulate rat T-cell proliferation via triggering of non-opioid receptors, whereas this stimulatory effect is abrogated by interaction of beta-end with opioid receptors. In the present study we provide evidence for this dualistic nature of beta-end by the identification of...

Metabolism of thyroid hormones was investigated in WAG/MBL rats that had been exposed to hexachlorobenzene (HCB). Serum thyroxine (T4) levels were lowered by 35.5%, whereas triiodothyronine (T3) levels were not changed. Bile flow, as well as T4 excretion in bile were increased by HCB treatment. Analysis of bile by HPLC revealed a more than 3...

Modification of auditory evoked startle responding using prepulse inhibition was used to examine the effects of trichloroethylene (TCE) exposure on auditory thresholds. Rats were exposed by inhalation to 0, 1500, or 3000 ppm TCE for 18 hours per day, 5 days a week for 3 weeks. Auditory thresholds for 5 and 20 kHz tones were measured before...

In previous studies we have shown that in HepG2 cells, as compared with fibroblasts, the low-density lipoprotein (LDL) receptor is only weakly down-regulated upon incubation of the cells with LDL. To explain this difference in down-regulation of the LDL-receptor activity, we studied simultaneously the intracellular processing of 125I-labelled...

We measured plasma levels of lipoprotein(a) (Lp(a)) in a sample of 152 Dutch adolescent mono- and dizygotic twin pairs and their parents. The distribution of Lp(a) levels was skewed, with the highest frequencies at low levels and was similar for adult men and women and their children. The relationship of Lp(a) concentrations with other...

In 1983 werd door de Geneeskundige Hoofdinspectie (GHI) een landelijke registratie van seksueel overdraagbare aandoeningen (SOA's) ingevoerd, naast het registratiesysteem van wettelijk aangifteplichtige ziekten. De gegevens voor de registratie worden door sociaal-verpleegkundigen, werkzaam bij GGD'en en geslachtsziekten-poliklinieken, verzameld....

This chapter provides a descriptive background of the driving task. Specifically it deals with those aspects of the driving context that are of special relevance to the human driver. This context is structurally determined by the triad driver-vehicle-road and functionally by situation-action elements that are revealed by driving task analyses....

The aim of the present study was to investigate whether hypothyroidism would affect the components of the rat plasma fibrinolytic system. Hypothyroidism was induced by feeding rats a thiouracil-containing diet for 2 weeks. During this period, half of the animals received subcutaneous injections of L-thyroxine (20 μg/kg daily) to restore thyroid...

An experiment was carried out to measure the vapour resistance of two-layer clothing ensembles as a function of air permeability of the outer layer, open or closed apertures, wind, and walking, both for the total ensemble and for the outer garment alone. Six subjects walked on a treadmill (0.0, 2.5, and 5 km.h-1) which was placed in a wind...

This paper delineates mental load and stress as two related concepts that originate from different theoretical frameworks. A proper distinction between the two concepts is important, not only for theory building, but because it may lead also to different interpretations of experimental results, and, conse-quently, to different recommendations in...

A knowledge based system "lifting-ADVISOR" is developed for health and safety practitioners to analyse manual lifting based on the revised NIOSH-equation. Furthermore a system to generate ideas for improvement was developed. Based on the specific results of the NIOSH-analysis, the system searches for those improvements which best fit the...
