Probabilistic quotient’s work and pharmacokinetics’ contribution: countering size effect in metabolic time series measurements [PDF]

BMC Bioinformatics, 2022
Abstract Metabolomic time course analyses of biofluids are highly relevant for clinical diagnostics. However, many sampling methods suffer from unknown sample sizes, commonly known as size effects. This prevents absolute quantification of biomarkers.

The Potential of Biochar Made from Agricultural Residues to Increase Soil Fertility and Microbial Activity: Impacts on Soils with Varying Sand Content

Agronomy, 2021
Different types of soil respond variably to biochar amendment. Soil structure and fertility are properties which strongly affect the impacts of biochar on soil fertility and microbial activity.

The Metabolism and the Respiratory Quotient of Excised Renal Tissue.

Experimental Biology and Medicine, 1926
Conclusions1. It is shown by complete double respiratory quotients that in the case of renal tissue, the error of the Warburg-Barcroft manometers is, on the average, ±0.014.2. The quotients were all between 0.7 and 1.0, and are fully accounted for by the oxidation of foodstuffs, without postulating the transformation of one into another.3. As evidenced

Temperature legacies predict microbial metabolic quotient across forest biomes

Global Ecology and Biogeography, 2022
AbstractAimPalaeoclimate legacies have been reported to influence microbial communities and carbon (C) stocks even after thousands of years. However, the direct and indirect influences of climate legacies on microbial C processes remain poorly understood and thus limit our capacity to predict how climate legacies regulate C cycling.

Tri-Parametric Assessment of α-Galactosidase A Activity, lysoGb3 and X-Inactivation Aids Genotype-Phenotype Categorization of Fabry Disease Female Patients. [PDF]

J Inherit Metab Dis
ABSTRACT Fabry disease (FD, OMIM 301500) is an X‐linked lysosomal storage disorder caused by deficient activity of lysosomal alpha‐galactosidase A (AGAL, E.C. 3.2.1.22) due to pathogenic variants in the GLA gene (HGNC:4296, Xq22.1). Plasmatic deacylated globotriaosylceramide (lysoGb3) is elevated in FD patients as a reflection of lysosomal accumulation
