Effects of tree pollen on throughfall element fluxes in European forests
linear mixed-effects modelling (LME). TF was measured in 1990–2018 during the main pollen season (MPS, arbitrary two months) in 61 managed, mostly pure, even-aged Fagus, Quercus, Pinus, and Picea stands ...
Comparison of 6 DNA extraction methods for isolation of high yield of high molecular weight DNA suitable for shotgun metagenomics Nanopore sequencing to detect bacteriaAbstractBackgroundResultsConclusion
must be able to isolate pure high molecular weight (HMW) DNA from complex metagenomics samples, without introducing any bias. New methods released on the market, and protocols developed at the research ...
Aluminium intake through the consumption of selected baby foods and risk characterization in a population of Brazilian infants aged 0 to 36 months
combining mean levels of Al in 171 samples of baby foods (infant formula, meat/vegetable purees, fruit purees, petit-suisse and cereals), analytically determined by inductively coupled plasma optical emission ...
Metagenomic Characterization of Multiple Genetically Modified Bacillus Contaminations in Commercial Microbial Fermentation Products
frequently employed for manufacturing microbial fermentation products such as food enzymes or vitamins. Although the fermentation product is required to be pure, GMM contaminations have repeatedly been ...
CHROMATOGRAPHIC FINGERPRINT DEVELOPMENT FOR THE DETECTION OF TRIBULUS TERRESTRIS IN PLANT FOOD SUPPLEMENTS
used to obtain chromatographic fingerprints. The pure plant extract was screened and optimized to develop a suitable method to obtain a specific fingerprint. The suitability of the method was evaluated ...
Analytical characterization of "etonitazepyne," a new pyrrolidinyl-containing 2-benzylbenzimidazole opioid sold online.
H NMR, and FTIR. The chromatographic data, together with the FTIR data, indicated the presence of a highly pure compound and already indicated a benzimidazole structure. The specific benzimidazole ...
Does arsenic pose a health concern after consumption of clay products?
arsenic (As) toxicity, because — certainly in case of pure clay- all arsenic in these supplements is expected to be present in the most toxic inorganic form (As). In terms of risk, the most important ...
Estimating the prevalence of diabetes mellitus and thyroid disorders using medication data in Flanders, Belgium.
Flanders (Belgium) for 2008: a purely administrative database containing data on dispensed medication, the Belgian National Health Interview Survey for self-reported medication and diagnoses, and a patient ...
Proof-of-concept study of a new LC-ESI-MS/MS-based assay to identify Aspergillus spp. in artificially mixed samples using species/genus-specific proteotypic peptides
prepared with strains of verified identity. The principle of the LC- ESI- MS / MS assay was based upon the detection of targeted Aspergillus species/genus-specific proteotypic peptide markers. Both pure ...
Generation and Characterization of Six Recombinant Botulinum Neurotoxins as Reference Material to Serve in an International Proficiency Test.
comparison. In conclusion, highly pure recombinant BoNT reference materials were produced, thoroughly characterized and employed as spiking material in a worldwide BoNT proficiency test organized by the EQ ...
