The vitamin B6 status of women suffering from premenstrual symptoms (PMS, n = 19) and a group of matched controls (n = 19) has been investigated. The women volunteering in the study were selected on strictly defined criteria. Several biochemical parameters of the metabolism of vitamin B6 and tryptophan were studied in blood and urine samples...

When the eyes pursue a fixation point that sweeps across a moving background pattern, and the fixation point is suddenly made to stop, the ongoing motion of the background pattern seems to accelerate to a higher velocity. Experiment I showed that this acceleration illusion is not caused by the sudden change in (i) the relative velocity between...

Combinations of dietary factors were studied in relation to breast-cancer occurrence among 133 breast cancer cases and 289 population controls in The Netherlands. Dietary factors were classified according to their possible mechanism of action, i.e., relating either to the intestinal microflora (total fat, fiber, fermented milk products) or to...

Eind 1990 verschenen in dit tijdschrift twee artikelen over het aantal met HIV geïnfecteerden in Nederland. Hieruit bleek dat het aantal HIV-seropositieven lager lag dan eerder werd aangenomen, maar dat desondanks een stijgend aantal AIDS-patiënten verwacht mocht worden. In uitkomsten liepen de twee onderzoeken niet ver uiteen. Jager et al....

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....

The objective was to compare the course of teenage pregnancies and deliveries with those of women between the ages of 20 and 29, using data from the 1989 National Obstetric Database (LVR) when approximately 76% of cases conducted by obstetricians were registered. 4500 teenage pregnancies were studied to compare the risk of preterm birth, low...

Induction and removal of cyclobutane thymine dimers and (6-4)photoproducts were studied in epidermal DNA isolated from UV-exposed hairless mice. For the detection of DNA damage, lesion-specific monoclonal antibodies were used in an immunoslotblot assay. Following the exposure of mice to 3.0 kJ m-2 UV-B, substantial removal of both thymine dimers...

Background. The validity of the results of studies using retrospectively collected information on exposures is often criticized, because cases may report differently from controls even if their true exposure status is the same. This study was performed to quantify the extent to which this effect (differential misclassification) may occur for...

Social class and ethnicity are important risk factors for small-for-gestational-age and preterm delivery in many countries. This study was performed to assess whether this is also the case in the Netherlands, a country with a high level of social security, relatively small income differences and easy access to medical care for all its...

Objective: To determine whether the sleeping position and the use of duvets in infants in 1994 had changed in comparison with earlier years. Design: Questionnaire survey. Setting: Nationwide investigation in infant welfare centres. Method: 194 infant welfare centres participated in the investigation. In November a questionnaire was completed...

Fluorescent contact chemical allergens provoke sensitization after application on both syngeneic and allogeneic skin grafts in mice. We attempted to determine whether the functional activity in a contact sensitization response of human skin graft was affected at the level of antigen uptake and migration. After xenogeneic skin transplantation, we...

SCID mice engrafted with human fetal thymus and liver tissue fragments (SCID-hu mice) are currently considered as a new tool in human immunotoxicological risk assessment. Testing of various immunotoxicants exerting thymotoxicity via different intrathymic target cell types is necessary for validation of this model. Therefore, SCID-hu mice were...

Background and objective. A low activated protein C (APC) response increases the risk of venous thrombosis, and possibly arterial disease. Apart from the factor V Leiden mutation, other factors may determine the level of APC response. In most studies on the association with arterial disease, cardiovascular risk factors were not appropriately...

In order to investigate the role of the hemostatic, fibrinolytic and inflammatory system in unstable angina, we assessed the levels of thrombin-antithrombin III (TAT), Prothrombin Fragment 1+2 (F1+2), plasmin-antiplasmin (PAP) and D-Dimer (DD) and of C-reactive protein (CRP) in 51 patients admitted to our CCU with severe unstable angina. Thirty...

The genetic component of human longevity is estimated at 30%. Which genes are involved in determining human longevity, however, is largely unknown. Genes that may affect human survival are susceptibility loci for major age related pathologies. Many studies are being performed to identify such loci for cardiovascular disease, dementia and...

To elucidate how the apolipoprotein (apo)E polymorphism and modifiable factors interact in explaining plasma lipid and apolipoprotein levels, we studied 1448 young adults (18 to 26 years old), participating in the European Atherosclerosis Research Study (EARS). Venous blood was collected after an overnight fast. Modifiable factors, eg, body mass...

Amifostine (Ethyol, WR-2721) is in use in the clinic as a protector against platinum-induced toxicities. We have previously reported that amifostine induced a potentiation of the antitumour activity of carboplatin in human ovarian cancer xenografts. An influence of amifostine on the pharmacokinetics of carboplatin, resulting in higher platinum...

Biomarkers of dietary exposure or nutritional status are sought actively to overcome limitations of traditional dietary methodology. We compared plasma and adipose tissue biomarkers for carotenoids and tocopherols. The data consisted of samples from 91 men and 122 women, ages 45-70 years, from the control group of the European Community...
