Identification of Flavouring Substances of Genotoxic Concern Present in E-Cigarette Refills

genotoxic substances in e-liquid flavours. 77 e-liquids, representative for the different flavour categories, were collected on the Belgian market and screened for their chemical composition using GC- MS. By ...

Allergic Asthma Favors Growth in the Lungs of Infected Mice.

a growing number of people worldwide. The impact of infections and microbiota composition on allergic asthma has been investigated frequently. Until now, however, there have been few attempts to investigate ...

Complete coding sequence of a novel picorna-like virus in a blackbird infected with Usutu virus.

specific for ORF1 confirmed the presence of high levels of this novel virus in the original sample. Nucleotide composition analysis suggests that blackbird arilivirus is of dietary (plant) origin. Health ...

Invasion by the Alien Tree Alters Ecosystem Functions in a Temperate Deciduous Forest

properties, litter quantity, litter species composition, and tree species composition. In invaded stands, average respiration rates were 5.6% higher for soil (without litter) and 32% higher for soil and litter ...

Fat-soluble vitamin intake from the consumption of food, fortified food and supplements: design and methods of the Belgian VITADEK study.

facilitate the recall of the consumed food items and portion pictures were used to facilitate the reproduction of the consumed portion sizes. Finally a composition table was compiled allowing for the ...

Development and validation of a HS/GC-MS method for the simultaneous analysis of diacetyl and acetylpropionyl in electronic cigarette refills

analytical methods have been published for determining e-liquid compositions, but concerns exist with respect to the lack of analytical evaluation. Hence in this study, a new HS / GC- MS-based method was ...

Sample substitution can be an acceptable data-collection strategy: the case of the Belgian Health Interview Survey.

2707 households (RR hh: 55.5%) participated. For the three successive (matched) substitutes, the RR dropped to 45%. The composition of the net sample resembles the one of the initial samples. Applying ...

Discrimination of three genetically close Aspergillus species by using high resolution melting analysis applied to indoor air as case study.

Abstract: BACKGROUND: Indoor air pollution caused by fungal contamination is suspected to have a public health impact. Monitoring of the composition of the indoor airborne fungal contaminants is therefore ...

Outbreak investigations and molecular characterization of foot-and-mouth disease viruses circulating in south-west Niger.

herd composition (presence of both cattle and small ruminants) was significantly associated with FMDV seropositivity as defined by NSP-positive results (p-value = .006). Of these positive sera, ...

An application of mass spectrometry for quality control of biologicals: Highly sensitive profiling of plasma residuals in human plasma-derived immunoglobulin.

prothrombotic FXI a was assessed with confident identification of a 1ng/mg spike. Moreover, different residuals compositions were profiled for various commercial Ig products. Using a quantitative label free ...
