We conducted two experiments with preruminant calves weighing 80 to 240 kg to study the long-term nutritional regulation of circulating IGF-I, thyroxine (T4), and triiodothyronine (T3). The two experiments were similar in design but were performed with calves of two live weight ranges: 80 to 160 kg (Exp. 1) and 160 to 240 kg (Exp. 2). In each...

The objective of this study was to evaluate the association of factor VII with dietary factors while also considering the R/Q353 polymorphism. Nutrition is an important determinant of coagulation factor VII, which is also genetically determined by the R/Q353 polymorphism. High levels of coagulation factor VII clotting activity (FVII:C) are...

Objective. Major mental disorders occur more frequently in deprived urban areas. This study examines whether this occurs for all mental disorders, including less serious ones. It further assesses whether such a concentration can be explained by the socioeconomic status (SES) of the residents concerned or that a cumulation of problems in deprived...

The toxicokinetics of the four stereoisomers of the nerve agent C(±)P(±)-soman were studied in anesthetized, atropinized guinea pigs for nose-only exposure to soman vapor. During exposure the respiratory minute volume (RMV) and respiratory frequency (RF) were monitored. Blood samples were taken for chiral gas chromatographic analysis of the...

Roundwood as a construction material is becoming more and more interesting to users. Using this wood in construction will increase the value of the material and may open new opportunities for construction design. In order to use roundwood for this application, suitable connectors and/or joints have to be developed, but before all, the strength...

This study examines the quality of life (QOL) of community living elderly people aged 55-74 with chronic, episodic or sporadic pain in the hip or knee and of a reference group without pain (total n = 306). Firstly, it was hypothesized that the experienced QOL is lower in people with more chronic pain. Secondly, the potential mediating and...

The term 'D-dimer assay' suggests, that these assays report the concentrations of the end-stage degradation product of crosslinked fibrin. This hardly occurs in patients. Degradation products of crosslinked fibrin rather occur with a wide range of molecular weights, and comprise various numbers of the D-dimer motif. Moreover, the numerical...

Coagulation factor VII activity (FVII:C) is a risk indicator for cardiovascular disease. It is related to serum-triglycerides and the R/Q353 polymorphism (alleles R and Q) in the gene coding for factor VII is strongly associated with factor VU[. The association of serum-triglycerides with factor VII may differ between the genotypes, but the...

Objective. To evaluate the effects of in utero and lactational exposure to polychlorinated biphenyls (PCBs) and dioxins on the mental and psychomotor development of infants. Design.

Autoantibodies against oxidized low-density lipoprotein (LDL) have been reported to be associated with atherosclerosis. However, data are not consistent. We compared the titres of autoantibodies to malondialdehyde-modified LDL in three groups, a case group with angiographically documented severe coronary stenosis (> 80% stenosis in at least 1...

To investigate the effects of the altered composition of the helper T cell compartment in ageing on the humoral response to influenza vaccine, we investigated correlations between helper T cell subsets and anti-influenza antibody responses in 23 JUNIEUR healthy young and 41 SENIEUR healthy elderly subjects. Naive helper T cell numbers (CD4...

Objectives: In studies on diet and cancer, diet assessment should address long-term intake. Therefore, the authors determined the 5-year reproducibility of a self-adminstered 150-item food frequency questionnaire (FFQ) used to assess dietary habits in the Netherlands Cohort Study on diet and cancer. Since the FFQ was repeated more than once, the...
