Estimation of the dissociation rate of unlabelled ligand-receptor complexes by a 'two-step' competition binding approach.
radioligand and monitoring its receptor binding after a fixed time. Based on the rationale that binding of both ligands is mutually exclusive and that they bind according to the law of mass action to a single ...
Multiple risk behaviour: increasing socio-economic gap over time?
behaviours, has been analysed with the purpose to assess socio-economic changes in multiple risk behaviour over time. METHODS: Cross-sectional data from the Belgian Health Interview Surveys 1997, 2001 and 2004 ...
Ligands, their receptors and... plasma membranes.
Bilayers Protein Structure, Secondary Receptors, Cell Surface Time Factors Abstract: Ligand-receptor interactions are customarily described by equations that apply to solutes. Yet, most receptors are present ...
Molecular mechanisms for the persistent bronchodilatory effect of the beta 2-adrenoceptor agonist salmeterol.
competing ligands. PURPOSE AND APPROACH: Computer-assisted simulations were performed to follow the receptor-occupation by a salmeterol-like ligand and a competing ligand as a function of time. The aptness of ...
Antagonist-radioligand binding to D2L-receptors in intact cells.
Dopamine D2 Spiperone Time Factors Abstract: D(2)-dopamine receptors mediate most of the physiological actions of dopamine and are important recognition sites for antipsychotic drugs. Earlier binding studies ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
phenol (NP) and tert-octylphenol (OP) in human placenta samples. After a short sample preparation time the extracts are analysed by UHPLC- MS / MS using negative electrospray ionization. Labeled internal ...
Optimising the case-crossover design for use in shared exposure settings.
time-varying confounding.We illustrated the consequences of different RSS using a simulation study informed by data on meteorological variables and Legionnaires’ disease. By randomising the events and exposure ...
Quantifying the burden of stillbirths before 28 weeks of completed gestational age in high-income countries: a population-based study of 19 European countries.
gestation in 2015 was 0·53 per 1000 births and did not significantly changed over time (RR 0·97, 95% CI 0·80-1·16) although changes varied widely between countries (RR s 0·62-2·09). Wide variation in the ...
Prevalence and incidence of anti-SARS-CoV-2 antibodies among healthcare workers in Belgian hospitals before vaccination: a prospective cohort study.
and 308 (36%) the December visit. OUTCOME MEASURES: A semiquantitative ELISA was used to detect IgG against SARS-CoV-2 in serum (Euroimmun) at 10 time points. In seropositive samples, neutralising ...
