Investigation of migrating substances from textile used as food contact material
overcome this issue, migration experiments were carried out using food simulants. Consequently, the bread bag was brought into contact with the simulants for bread using accelerated time and temperature ...
Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids
limit the transfer of the matrix to the column. The headspace temperature was chosen in order to obtain an optimal transfer of the target components to the headspace with minimal transfer of the matrix ...
Failure to Remove Bluetongue Serotype 8 Virus (BTV-8) From Produced and Derived Bovine Embryos and Subsequent Transmission of BTV-8 to Recipient Cows After Embryo Transfer.
and derived bovine blastocysts to BTV-8 followed by different washing protocols, including longer exposure times (up to 120 s) to 0.25% trypsin at room temperature or at 37°C. None of the washing ...
The Use of Tenax® as a Simulant for the Migration of Contaminants in Dry Foodstuffs: A Review
come into contact with food specifies the use of the adsorbent poly(2,6‐diphenylphenylene oxide) or Tenax® as a simulant for dry foodstuffs. Already in 2010, Tenax® migration profiles in the temperature ...
A simple dilute-and-shoot method for screening and simultaneous quantification of nicotine and alkaloid impurities in electronic cigarette refills (e-liquids) by UHPLC-DAD
excluded. In addition, small changes to the column temperature, pH and molar concentration of the mobile phase buffer were deliberately introduced in order to assess the robustness of the method. Only ...
European all-cause excess and influenza-attributable mortality in the 2017/18 season: should the burden of influenza B be reconsidered?
mortality was estimated using the FluMOMO algorithm, incorporating influenza activity based on clinical and virological surveillance data, and adjusting for extreme temperatures. Results Excess mortality was ...
Occurrence and identification of spore-forming bacteria in skim-milk powders
various tests. Of the isolates identified, 68% were Bacillus licheniformis, a facultative anaerobe that can survive and grow at mesophilic and thermophilic temperatures, making it difficult to eliminate in ...
Temperature-related changes in airborne allergenic pollen abundance and seasonality across the northern hemisphere: a retrospective data analysis
might, through rising temperatures, alter allergenic pollen biology across the northern hemisphere. We aimed to analyse trends in pollen seasonality and pollen load and to establish whether there are ...
Sensitivity of African swine fever virus (ASFV) to heat, alkalinity and peroxide treatment in presence or absence of porcine plasma.
Swine Fever Virus Animals Antacids Hot Temperature Hydrogen Peroxide plasma Swine Virus Inactivation Abstract: African swine fever virus (ASFV) is a highly resistant viraemic virus with devastating ...
Relationships between aeroallergen levels and hospital admissions for asthma in the Brussels-Capital Region: a daily time series analysis.
holidays, mean temperature and relative humidity. Effect modification by age and air pollution (PM, NO, O) was tested. RESULTS: A significant increase in asthma hospitalizations was observed for an ...
