Polychlorinated biphenyls (PCBs) dissolved in dietary fat are absorbed in the gastrointestinal tract by the enterocytes in combination with the fatty acid proceeding from the lipid hydrolysis in the gut lumen. The effect of fatty acid absorption on the uptake and transport of 14 PCBs in enterocytes was studied using monolayers of the human...

Organosilicon coatings provide good optical and mechanical properties and are excellent candidates for the modification of the surface energy of polymers. These coatings can be deposited by plasma polymerization of hexamethyldisiloxane (HMDSO) under atmospheric pressure and at room temperature. The resulting films can range from soft,...

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...

Numerical models are proposed that are able to describe the current-voltage (I-V) behaviour of two Cu2ZnGeSe4 (CZGSe) solar cells measured under different illuminations at 300 K. In the model, the doping density of the CZGSe layer and the mobility of carriers are determined by capacitance-voltage (C-V) profiling and AC field Hall effect...

Environmental research is ongoing to predict and to mitigate the noise impact of heavy weapons or explosives. In the densely populated area of the Netherlands this is of particular interest for the Ministry of Defence as the shock waves can propagate over large distances. In this research program the mitigation of shock waves by means of a sound...

Purpose: Home-based rehabilitation is a promising alternative to regular center-based stroke rehabilitation. The objective of this study was to identify what is currently known about determinants that influence the implementation of home-based stroke rehabilitation (HBSR) in clinical practice. Methods: A systematic review of determinants of HBSR...

In this review, we briefly summarize the possible signals crossing the placental barrier and discuss the molecular mechanisms of epigenetic programming in the developing fetus leading to increased athero-susceptibility of the vessel wall. © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Here, controlled p-type doping of poly(2-methoxy-5-(20-ethylhexyloxy)- pphenylene vinylene) (MEH-PPV) deposited from solution using tetrafluorotetracyanoquinodimethane (F4-TCNQ) as a dopant is presented. By using a co-solvent, aggregation in solution can be prevented and doped films can be deposited. Upon doping the current-voltage...

AMOLED displays using oxide TFTs and high-quality moisture barrier were fabricated on ultrathin, flexible plastic substrates to give maximum mechanical flexibility. Total display thickness is below 150μm, and repeated rollability at 1 cm roll radius has been demonstrated. Electrical/Mechanical characteristics and reliability of the flexible...

The charge injection barriers in organic field-effect transistors (OFETs) seem to be far less critical as compared to organic light-emitting diodes (OLEDs). Counter intuitively, we show that the origin is image-force lowering of the barrier due to the gate bias at the source contact, although the corresponding gate field is perpendicular to the...

A proper understanding of coastal development during periods of rapid sea-level rise is a prerequisite for the prediction of future coastal response to the expected acceleration in sea-level rise. However, the development of back-barrier basins, especially in river-mouth areas, during such periods is still not well understood. Here we show the...

Objective: external cephalic version (ECV) is a relatively simple and safe manoeuvre and a proven effective approach in the reduction of breech presentation at term. There is professional consensus that ECV should be offered to all women with a fetus in breech presentation, but only up to 70% of women eligible for ECV undergo an ECV attempt. The...

Aim: The aim of this study was to gain insight into contraception practised and related to breastfeeding duration. Methods: Mothers with infants up to 6 months received a questionnaire on infant feeding (breast or formula feeding) and contraception (hormonal or non-hormonal methods). Estimates of the time interval between resuming contraception...

In the development of multiple sclerosis (MS), (re)activation of infiltrating T cells by myelin-derived Ags is considered to be a crucial step. Previously, αB-crystallin has been shown to be an important myelin Ag to human T cells. Since αB-crystallin is an intracellular heat shock protein, the question arises at what stage, if any, during...

Dietary fiber intake is associated with lower incidence and mortality from disease, but the underlying mechanisms of these protective effects are unclear.We hypothesized that β2→1-fructan dietary fibers confer protection on intestinal epithelial cell barrier function via Toll-like receptor 2 (TLR2), and we studied whether β2→1-fructan chain...

We report on a low substrate temperature (110°C) remote microwave plasma-enhanced chemical vapor deposition (PECVD) process of silicon nitride barrier layers against moisture permeation for organic light emitting diodes (OLEDs) and other moisture sensitive devices such as organic photovoltaic cells (OPVs). Specifically, the influence of the SiH4...

The availability of a high performance thin-film barrier is the most critical challenge in upscaling and commercializing flexible OLED products. We report a flexible thin-film-barrier technology that meets lifetime specifications for OLED lighting, and demonstrate it in rollable QVGA a-IGZO AMOLED displays. Roll-to-roll manufacturing of this...

Pharmaceuticals and chemicals are subjected to regulatory safety testing accounting for approximately 25% of laboratory animal use in Europe. This testing meets various objections and has led to the development of a range of 3R models to Replace, Reduce or Refine the animal models. However, these models must overcome many barriers before being...

Older people with intellectual disability (ID) are characterized by low physical activity (PA) levels. PA is important for reducing health risks and maintaining adequate fitness levels for performing activities of daily living. The aim of this study was to explore preferences of older adults with ID for specific physical activities, and to gain...

Flooding of the southern part of the North Sea occurred between 9000 and 8000 BP, when the rate of relative sea-level rise was on the order of 0.7 cm per year for the Dover Strait Region and 1.6 cm per year for the area north of the Frisian Islands, forcing the shoreline to recede rapidly. When relative sea-level rise decelerated after 7000 BP...
