Limits of Fat Quantification in the Presence of Iron Overload [PDF]

open access: yesJournal of Magnetic Resonance Imaging, 2021
BackgroundChemical shift encoded magnetic resonance imaging (CSE‐MRI)‐based tissue fat quantification is confounded by increased R2* signal decay rate caused by the presence of excess iron deposition.PurposeTo determine the upper limit of R2* above which it is no longer feasible to quantify proton density fat fraction (PDFF) reliably, using CSE‐MRI ...

Determination of the limit of quantification of the calorimeter using a mixture of benzoic acid and silicon dioxide [PDF]

open access: yesHemijska Industrija, 2011
In recent years quality control has received a great attention in laboratory work. Implementation of the international standard ISO/IEC 17025 is necessary for any laboratory that wishes to establish quality control in its work.

Combining multiple markers significantly increases the sensitivity and precision of eDNA‐based single‐species analyses

open access: yesEnvironmental DNA, 2023
The analysis of environmental DNA (eDNA) is becoming integrated as an established biomonitoring tool, often characterized by detection limits exceeding those of conventional counterparts. However, further improving the sensitivity of these methods may be

Limitations and challenges of genetic barcode quantification [PDF]

open access: yesScientific Reports, 2017
AbstractGenetic barcodes are increasingly used to track individual cells and to quantitatively assess their clonal contributions over time. Although barcode quantification relies entirely on counting sequencing reads, detailed studies about the method’s accuracy are still limited.

A statistical model for calibration and computation of detection and quantification limits for low copy number environmental DNA samples

open access: yesEnvironmental DNA, 2021
Environmental DNA (eDNA) has been increasingly utilized by academic, industry, and government groups for environmental monitoring due to its efficiency in regards to both time and cost, as well as non‐invasiveness to target organisms, and reduced ...

The lower limit of quantification in pharmacokinetic analyses [PDF]

open access: yesJournal of Veterinary Pharmacology and Therapeutics, 2019
Pharmacokinetic (PK) analyses rely fundamentally on independent measurements of drug concentrations in biological matrices, traditionally using chromatographic analytical methods. These methods have imperfect performance and introduce measurement error to the experiment.

Statement on the risk assessment of maximum residue levels (MRLs) for oxamyl in view of consumer protection

open access: yesEFSA Journal, 2023
In accordance with Article 43 of Regulation (EC) No 396/2005, the European Commission requested EFSA to perform a risk assessment of the existing maximum residues levels (MRLs) for oxamyl considering the new toxicological reference values.

Optimization of limit of detection in Taylor dispersion analysis: Application to the size determination of vaccine antigens

open access: yesTalanta Open, 2023
The development of a new vaccine requires the precise characterization of all the physicochemical parameters of the vaccine antigens, which are the molecules that induce the immune response.
