Nanopore sequencing technology: a new route for the fast detection of unauthorized GMO.

system for unauthorized GMO, we have recently developed a new workflow based on DNA walking to amplify unknown sequences surrounding a known DNA region. This DNA walking is performed on transgenic ...

Relative contributions of recommended food environment policies to improve population nutrition: results from a Delphi study with international food policy experts.

facilitate benchmarking of the implementation of food environment policies globally. DESIGN: A two-round Delphi study was performed in 2015, whereby international food policy experts (n Round1 27, n Round2 21) ...

Prevalence of drug use during sex amongst MSM in Europe: Results from a multi-site bio-behavioural survey.

Multivariable multi-level logistic random-intercept model (random effect of study site) was estimated to identify factors associated with the use of alcohol, cannabis, party drugs, sexual performance enhancement ...

Relationships between aeroallergen levels and hospital admissions for asthma in the Brussels-Capital Region: a daily time series analysis.

were performed. Effects up to 6 days after exposure were captured by combining quasi-Poisson regression with distributed lag models, adjusting for seasonal and long-term trends, day of the week, public ...

Time-and-motion tool for the assessment of working time in tuberculosis laboratories: a multicentre study.

1060 specimens were tested using four laboratory assays. The number of specimens per batch varied from one to 60; a total of 64 recordings were performed. Theoretical hands-on times per specimen (TTPS) ...

Performance of in silico models for mutagenicity prediction of food contact materials

these predictions, the capacity of the prediction models to generate (sufficiently) reliable results for a particular type of compounds needs to be evaluated. In the current study, performance parameters to predict ...

Short-term effects of nitrogen dioxide on hospital admissions for cardiovascular disease in Wallonia, Belgium.

hospitals. Analyses were performed using the quasi-Poisson regression model adjusted for seasonality, long-term trend, day of the week, and temperature. Our study confirms the existence of an association ...

Seroprevalence and risk factors related to small ruminant lentivirus infections in Belgian sheep and goats.

hobbyist sector makes it difficult to evaluate the risk of SRLV transmission from non-certified to SRLV free certified farms. We performed a nationwide SRLV seroprevalence study based on a stratified ...

Identification of coffee leaves using FT-NIR spectroscopy and SIMCA.

in order to identify coffee leaves taxa. Investigation by Fourier — Transform near infrared spectroscopy (FT- NIRS) was performed on nine Coffea taxa leaves harvested over one year in a tropical ...

Development and validation of an integrated DNA walking strategy to detect GMO expressing cry genes

additional GMO and additional sequences of interest. Results The performance of the proposed bidirectional DNA walking method anchored on the CryAb/c genes has been evaluated in a first time for its ...
