In a method for preparing a blood sample for subsequent processing in a mass spectrometry laboratory, substances of interest are extracted from whole blood, blood plasma or blood serum immediately after the blood sample has been taken from a subject. The extraction is carried out by means of ...
Interestingly, while no differences in PFAS levels occurred in whole fish by capture location, fillets had differences that were dependent upon catch location. In contrast to lipophilic organic pollutants such as PCBs, the binding of PFOS to liver and blood proteins contributes to the higher levels...
investigated the metabolic profiling of urine and blood plasma in rat models of drug addiction and found that TCA cycle intermediates significantly changed in the urine of morphine addicted rats, while 3-hydroxybutyric acid, l-tryptophan, cystine levels significantly decreased in plasma31. Similarly, ...
Blood samples from 2373 individuals were randomly chosen for PFAS analysis and PFAS levels could be detected in >95% of the study population. PFAS (PFHxS, PFOA and PFOS) were analyzed in plasma by non-targeted metabolomics (Metabolon Inc, Morrisville, NC; UAS). After the analysis, the PFAS...
Fetal blood group genotyping from DNA from maternal plasma: an important advance in the management and prevention of haemolytic disease of the fetus and ne... The cloning of blood group genes and subsequent identification of the molecular bases of blood group polymorphisms has made it possible to...
Blood samples were centrifuged and/or fractionated at the local sampling center and afterwards transported to the central laboratory where they were stored at − 80 °C in a biobank within 12 h after sampling. Plasma and serum were conserved at − 80 °C. All laboratory analyses were ...
(2021, 2022a), but estimated by translating external doses to internal blood concentrations using kinetic models. For assessment of risks upon combined exposure to PFASs, such RPFs may be of use to take potency differences in PFASs into account. In that regard, external RPFs may be of use...
Ginger charcoal can warm meridians and stop bleeding, and is mainly used to treat vomiting, epistaxis, metrorrhagia and blood loss due to yin deficiency”. Ginger can be used for medicinal purposes by simmering. Roasted ginger appears as a common method of fresh ginger medicine, and has the ...
Given that one measurement of PFAS in blood is indicative of cumulative exposure spanning 5–10 years [85], and considering the prolonged development period of RA, this approach may overlook crucial long-term chemical influences, thereby introducing potential confounding variables. This study conducted...
The blood samples were collected by research nurses via venipuncture using K2-EDTA vacutainers (Fisher Scientific). Subsequently, the collected samples were centrifuged at 2000×g for 10 min, and the resulting plasma was transferred into polypropylene tubes for storage at − 20 °C until furth...
